1.1 CEQA Requirements
This project is subject to the requirements of the California Environmental Quality Act (CEQA). The lead
agency is City of La Quinta (City). The purpose of this Initial Study (IS) is to provide a basis for deciding
whether to prepare an Environmental Impact Report (EIR), a Mitigated Negative Declaration (MND), or a
Negative Declaration (ND). This IS is intended to satisfy the requirements of the CEQA (Public Resources
Code, Div 13, Sec 21000-21177) and the State CEQA Guidelines (California Code of Regulations, Title 14,
Sec 15000-15387). CEQA encourages lead agencies and applicants to modify their projects to avoid
significant adverse impacts.
Section 15063(d) of the State CEQA Guidelines states the content requirements of an IS as follows:
1. A description of the project including the location of the project;
2. An identification of the environmental setting;
3. An identification of environmental effects by use of a checklist, matrix, or other method, provided that
entries on a checklist or other form are briefly explained to indicate that there is some evidence to
support the entries;
4. A discussion of the ways to mitigate the significant effects identified, if any;
5. An examination of whether the project would be consistent with existing zoning, plans, and other
applicable land use controls; and
6. The name of the person or persons who prepared or participated in the IS.
Environmental Analysis Methodology
The State CEQA Guidelines present several "Special Situations" that include unique requirements for
environmental evaluation. Section 15183 discusses "Projects Consistent with a Community Plan, General
Plan, or Zoning." Subsection (a) states, "CEQA mandates that projects which are consistent with the
development density established by existing zoning, community plan, or general plan policies for which an
EIR was certified shall not require additional environmental review, except as might be necessary to
examine whether there are project -specific significant effects which are peculiar to the project or its site.
City of La Quinta Highway 111 Corridor Specific Plan 1-1
Project Information
This streamlines the review of such projects and reduces the need to prepare repetitive environmental
studies." This project is consistent with the City's current 2035 General Plan, which is included in Section 4,
References.
The proposed Highway 111 Corridor Specific Plan would enable proposed future projects to consider this
impact analysis when evaluating their potential environmental impacts. Where sufficiently addressed herein,
future development may be considered "within the scope" of this environmental analysis. As a
programmatic -level document, however, this CEQA analysis is not anticipated to provide sufficient detail to
fully address the project -specific impacts of all future development. Indeed, it is anticipated that additional
environmental technical studies or CEQA documentation may be needed for future projects once sufficient
details are known. In such cases, the necessary environmental studies and documentation may be
conducted at the time of proposal. It is anticipated that CEQA compliance for future projects would be tiered
from this document.
1.2 Project Background
The City is preparing a Highway 111 Corridor Specific Plan (hereinafter "Specific Plan" or "Project") and
Highway 111 Development Code to facilitate the establishment of Highway 111 as a vibrant mixed -use
corridor. The Highway 111 Corridor (Corridor) consists of a roughly two-mile stretch of businesses, mostly
retail, located along the La Quinta portion of Highway 111, between Washington and Jefferson Streets.
Approximately 75% of the City's sales tax is generated in the Corridor. The Specific Plan is intended to
guide the orderly development and redevelopment of local infrastructure, businesses, and housing within
the Corridor. The City intends that these improvements would provide a unifying blueprint for one
interconnected space to shop, live, work, and play, accessible via Highway 111, the Coachella Valley (CV)
Link, and other multi -use paths. The Highway 111 Development Code is a land use policy that establishes
development standards for the Corridor's expansion, incorporating location -specific guidelines like active
frontage, and offering detailed information on qualifying uses, as well as additional requirements and
permissions for future growth. The CV Link is a 40-mile pathway providing access to pedestrians, bicyclists,
and low -speed electric vehicles on a dual pathway that runs mostly parallel to Highway 111 along the
Whitewater Wash just north of the Project area. This regional pathway connects Palm Springs to Thermal
and is expected to draw 13,500-16,000 users annually (City of La Quinta, 2019).
Population growth anticipated by the Specific Plan is assumed to be captured within the City's current
General Plan; however, the new Specific Plan would supersede and effectively replace existing Specific
Plans that were previously adopted within the Project vicinity. Previously adopted Specific Plans are as
follows:
• SP 1987-011 Washington Park
• SP 1989-014 111 La Quinta Center
• SP 1996-027 Jefferson Plaza
• SP 1996-028 Dune Palms Center
• SP 1997-029 Centre at La Quinta
• SP 1999-036 La Quinta Corporate Center
• SP 2000-043 Point Happy
• SP 2000-047 La Quinta Court
• SP 2003-066 The Pavilion
• SP 2005-075 Komar Desert Center
• SP 2008-085 Coral Mountain Apartments
City of La Quinta Highway 111 Corridor Specific Plan 1-2
Project Information
Additional details regarding population growth are provided in Section 1.4 below.
This Initial Study/Mitigated Negative Declaration (IS/MND) has been prepared in accordance with CEQA to
provide a programmatic -level review of potential environmental impacts associated with the proposed
Highway 111 Corridor Specific Plan.
1.3 Project Location and Existing Setting
The Specific Plan project area is located along Highway 111 within the City of La Quinta, which is in the
County of Riverside. The City is located in the foothills of the Santa Rosa Mountains in the Coachella
Valley. The Valley extends about 45 miles southeast from the San Gorgonio Pass to the northern shore of
the Salton Sea and the neighboring Imperial Valley. Cities in the vicinity of La Quinta include the cities of
Palm Springs, Palm Desert, Rancho Mirage, and Indio, among others.
The Project area encompasses just over approximately 410 acres (-0.64 square miles) of the Highway 111
Corridor spanning from approximately Washington Street on the west end to Jefferson Street on the east;
and from the Whitewater flood control channel on the north to Avenue 47, and Vista Coralina Lane on the
south.
Development along Highway 111 in the Project area comprises a mix of uses, principally commercial (e.g.,
big box retail, strip center, grocery, restaurants, auto dealers) and large surface parking lots. Some
residential uses are located to the south. There are a few vacant parcels scattered throughout the Project
area. Landscaping consists of street trees and other ornamental xeriscape. Transportation facilities are
largely improved with a full street network, curbs and sidewalks, and crosswalks at major intersections.
Figure 1-1, Project Vicinity, presents the Project area within the context of the City. Figure 1-2, Current and
Potential Development Areas, presents the Highway 111 Corridor within the City and outlines the seven
development areas along the corridor.
1.4 Project Description
Purpose
The proposed Specific Plan provides guidance for implementing development within the Project area. The
draft Specific Plan is available for public review by contacting the City of La Quinta Design and
Development Department.
As noted above, the Specific Plan is consistent with the City's current 2035 General Plan (hereinafter
"General Plan") and furthers the objectives of the General Plan by providing a more detailed planning
document for development of specific sites and streetscape improvements. This Specific Plan is intended to
provide a comprehensive development approach for Highway 111 focused on public connectivity, mixed -
use development, and enhanced transportation options. Introduction of mixed -use development is essential
for the future of the Highway 111 Corridor. By combining commercial, residential, and recreational spaces,
the Highway 111 Corridor is intended to become a vibrant urban environment that encourages economic
growth and enhances the quality of life. Integration of pedestrian -friendly pathways and dedicated bike
lanes, for example, would ensure seamless connectivity between residential areas, commerce, and cultural
hubs, fostering a more engaged and active community. The Highway 111 Corridor is currently heavily
vehicle -centric, and this Specific Plan aims to promote public accessibility through residential and retail
densification and introduction of more compatible land uses to improve the Corridor's urban landscape. This
holistic development approach is anticipated to revitalize the region and serve as a catalyst for urban
renewal and community well-being.
City of La Quinta Highway 111 Corridor Specific Plan 1-3
Project Information
The City of La Quinta Municipal Code sets forth site -specific standards and regulations that govern the size,
shape, and type of use that would occur in accordance with the proposed Project. The proposed Specific
Plan is intended to be built out over the course of 20 to 25 years. Economically feasible buildout under the
Specific Plan could result in the following additional square footages (sf):
• Residential: 1,464,000 to 1,837,000 sf
• Retail: 107,000 to 194,000 sf
• Office: 82,000 sf
• Hotel: 150,000 to 250,000 sf
Population
In 2020, La Quinta's permanent population was estimated to be 40,660 individuals. However, during the
winter months, the seasonal population swells with an estimated additional 10,000 individuals, marking a
25% increase in the City's total population during that period (City of La Quinta, 2022). Population growth is
expected to rise along the Highway 111 Corridor over the next two decades and beyond. This Specific Plan
aligns with the objectives of the City's General Plan, which prioritizes mixed -use development while
promoting seamless public connectivity and optimal land use to accommodate future generations.
Embracing this growth is advantageous as it enables a more efficient and sustainable utilization of space,
enhancing the accessibility of amenities and services for residents while promoting economic vitality and
community engagement.
Furthermore, this Specific Plan aligns with the City's General Plan Housing Element Goal H1: Provide
opportunities that meet the diverse needs of the City's existing and projected population (City of La Quinta,
2022). The proposed densification along the Highway 111 Corridor aims to offer enhanced and abundant
housing options, including urban housing options, to accommodate an expanding population. This Specific
Plan would repurpose areas that were formerly underutilized, such as parking lots and large-scale retail
establishments, transforming them into vibrant residential spaces with pedestrian -friendly uses. By
maximizing the potential of these previously inefficiently utilized areas, the Project not only addresses the
pressing need for housing but also revitalizes the urban landscape, fostering a more dynamic and
sustainable community environment.
Development Strategy Areas
The proposed Specific Plan establishes seven Development Strategy Areas (DSAs), which provide a vision
for future land uses, development standards, and design guidelines as envisioned by the City. The seven
DSAs, and their development focus, are provided in Table 1.1.

City of La Quinta Highway 111 Corridor Specific Plan 1-6
Project Information
Highway 111 Development Code
The Highway 111 Development Code will govern land development along the Corridor and is designed to
achieve consistent and aesthetically pleasing urban environments by prioritizing physical structure over the
strict exclusion of land uses. Unlike traditional zoning codes, which focus mainly on dictating permitted land
uses and activity levels, the Highway 111 Development Code concentrates on ensuring that buildings
harmonize with their surroundings, allowing for a more diverse mix of activities within them. The Highway
111 Development Code seeks to integrate key land use and urban form objectives into adaptive
development policies under the Highway 111 Mixed Use (HMU) Zone.
These policies promote active frontages, where building facades engage with the street to create a vibrant
pedestrian environment with visible goods, services, and activities. At the same time, the code emphasizes
designing future development — whether new, infill, or replacement — to coexist harmoniously with existing
auto -oriented uses along the Corridor, ensuring the continued presence of commercial activities like drive-
thru establishments. Additionally, the code proposes a pedestrian -friendly block street network that
supports mixed -use, townhomes, and retail developments, encouraging off-street paths and using
roadways from signalized or roundabout intersections as access points and anchors for the block network.
This approach ensures that new developments align with the desired character and vision of a
neighborhood or community.
Implementing the Highway 111 Development Code in the Highway 111 HMU Zone would enhance the
community by offering clear guidelines that govern the visual aspects of development, ensuring a cohesive
aesthetic and harmonious atmosphere while simplifying and expediting the development process. By
focusing on the physical form and design of development, rather than simply regulating land use, the
Highway 111 Development Code will support the creation of walkable, diverse neighborhoods that reflect
the unique character and identity of each community.
1.5 Required Agency Approvals
The City's approval of the proposed Specific Plan would not require any permits or approvals by other
public agencies. Actions subsequent to the Specific Plan that support implementation of the General Plan
may require permits or approvals by other public agencies. The following permits and/or approvals will be
conducted concurrently with the proposed Specific Plan:
City of La Quinta —Zone Change and Development Code Update (Zoning Ordinance Amendment).
Future implementation of development proposed by the Specific Plan may require the following approvals:
• U.S. Army Corps of Engineers (USACE) — Section 404 of the Clean Water Act (applicable to fill
within jurisdictional waterways and wetlands).
• State Water Resources Control Board (SWRCB) — Construction General Permit and Storm Water
Pollution and Prevention Plan (SWPPP, applicable to certain construction activities greater than
one acre in disturbance).
• U.S. Fish and Wildlife Service (USFWS) — Biological Opinion or Letter of Concurrence, for
Endangered Species Act consultation (applicable to activities that adversely affect federally listed
species).
• California Department of Transportation (Caltrans) — Encroachment Permit (applicable to activities
that encroach within state highway facilities).
• Coachella Valley Water District (CVWD) — Development Services permits and approvals for
domestic water connections and Encroachment Permits for work within CVWD Right -of -Way.
City of La Quinta Highway 111 Corridor Specific Plan 1-7
Project Information
1.6 Mitigation, Monitoring, and Reporting Program
The Mitigation, Monitoring, and Reporting Program (MMRP) for this IS/MND is included in Appendix A. The
MMRP includes a summary of all mitigation measures and description(s) of how each mitigation measure
would be implemented to ensure all potential impacts associated with the Project or future development
projects would result in a less than significant environmental impact.
1.7 Tribal Consultation
CEQA requires that lead agencies determine whether a proposed Project would have a significant effect on
tribal cultural resources. The CEQA Guidelines define tribal cultural resources as: (1) a site, feature, place,
cultural landscape, sacred place, or object with cultural value to a California Native American Tribe that is
listed or eligible for listing on the California Register of Historical Resources (CRHR), or on a local register
of historical resources as defined in PRC Section 5020.1(k); or (2) a resource determined by the Lead
Agency, in its discretion and supported by substantial evidence, to be significant according to the historical
register criteria in PRC Section 5024.1(c), and considering the significance of the resource to a California
Native American Tribe.
Pursuant to Senate Bill 18 (SB 18), prior to the adoption or any amendment of a city or county's general
plan, proposed on or after March 1, 2005, the city or county shall conduct consultations with California
Native American Tribes that are on the contact list maintained by the Native American Heritage
Commission (NAHC) for the purpose of preserving or mitigating impacts to places, features, and objects
described in Sections 5097.9 and 5097.995 of the Public Resources Code (PRC) that are located within the
city or county's jurisdiction.
Similarly, pursuant to Assembly Bill 52 (AB 52), the CEQA Lead Agency for any project for which a Notice
of Preparation, Notice of Mitigated Negative Declaration, or Notice of Negative Declaration is filed on or
after July 1, 2015, must provide notification to tribes that may be traditionally and culturally affiliated to the
geographic area where the project is located. The City conducted concurrent SB 18 and AB 52
consultation. Seventeen Native American Tribes were contacted, pursuant to the list acquired from the
NAHC, and PRC § 21080.3.1 and Chapter 532 Statutes of 2014 (i.e., AB 52), as part of preparing this
environmental review document. Refer to Section 3.18, Tribal Cultural Resources, for additional
information.

Environmental Analysis — Aesthetics
3 Environmental Analysis
3.1 Aesthetics
Except as provided in Public Resources Code Section 21099, would the project:
a) Have a substantial adverse effect on a scenic ✓
vista?
b) Substantially damage scenic resources,
including, but not limited to, trees, rock ✓
outcroppings, and historic buildings within a
state scenic highway?
c) In non -urbanized areas, substantially degrade
the existing visual character or quality of public
view of the site and its surroundings? (Public
Views are those that are experienced from ✓
publicly accessible vantage point). If the project
is in an urbanized area, would the project
conflict with applicable zoning and other
regulations governing scenic quality?
d) Create a new source of substantial light or
glare which would adversely affect day or ✓
nighttime views in the area?
Existing Aesthetic
There are no adopted scenic vistas within the Project area. La Quinta is a desert resort city situated in
Riverside County, California. Positioned between Indian Wells and Indio, California, it is one of the nine
cities comprising the scenic Coachella Valley (CV), with vistas of the Little San Bernardino, Santa Rosa,
and San Jacinto Mountains. Views of the Indio Hills and other scenic hilly regions are present from various
locations within the City. The La Quinta General Plan land use designation for the Highway 111 Corridor is
General Commercial (GC), and consists of a mix of retail stores, office spaces, restaurants, and service -
oriented establishments (City of La Quinta, 2022). The Highway 111 Corridor contains a mix of zoning
including Regional Commercial (CR), Community Commercial (CC), Commercial Park (CP) and Medium
Density Residential (RM).
While the construction of new buildings and structures within the City may potentially obstruct views of the
surrounding natural landscape, the policies outlined in the Community Development, Land Use, Circulation,
and Natural Resources sections of the City of La Quinta 2035 General Plan are designed to mitigate such
impacts (City of La Quinta, 2022). These policies mandate that any future development carefully consider
the preservation of scenic vistas and resources. By integrating these considerations, the City ensures that
both growth and environmental stewardship are balanced, maintaining the aesthetic appeal and natural
beauty of the area for future generations. This approach not only supports sustainable urban planning but
also enhances the quality of life for all residents by preserving the visual access to nature amidst urban
expansion.
City of La Quinta Highway 111 Corridor Specific Plan 3-1
Environmental Analysis — Aesthetics
Furthermore, the implementation of the Highway 111 Development Code along the Highway 111 Corridor
would prioritize the physical form of buildings and public spaces over strict land use categories. As
previously described in Section 1.4, the Highway 111 Development Code is an aesthetic -focused approach
to development and land use planning. By emphasizing the design, scale, and appearance of buildings
within a specific area, the Highway 111 Development Code seeks to create cohesive and visually appealing
communities that reflect the character and identity of the region. This approach will ensure that new
construction along the Highway 111 Corridor aligns with the area's vision for growth and preserves its
unique character.
a) Have a substantial adverse effect on a scenic vista?
Less than Significant Impact: A scenic vista can be described as a picturesque scene of open space with
little or no intrusions. The Project encompasses various enhancements to the public infrastructure in order
to provide a more suitable environment for commercial enterprises to operate and serve the community,
residential, and hotel space, as well as streetscape beautification and other improvements to public rights -
of -way, sidewalks, and public open spaces. The Specific Plan outlines proposed urban design concepts
that showcase the planned streetscape and community improvements within the Project area.
The Project aims to improve the accessibility, function, and aesthetic of the Highway 111 Corridor, providing
a lasting community benefit. A guiding principle of the City of La Quinta's General Plan is that it remains a
resort -oriented community, which ensures maintenance and improvements of opportunities for La Quinta to
be recognized as a top resort and recreation destination (City of La Quinta, 2022). As a resort destination,
aesthetics are key and would be ideally improved upon with this proposed Project. Should the Project utilize
the Moderate scenario, impacts on public scenic views would be less than significant as the existing
aesthetic and scenery along the Highway 111 Corridor contains solely mixed commercial use parcels. The
corridor has limited land uses other than commercial (i.e., residential, office, and hotel) as well as improved
pedestrian and bicycle accessibility. The Moderate Scenario would also utilize lower density development,
thus reducing potential impacts on scenic resources. Should the Project utilize the Max Scenario, impacts
on scenic vistas may be slightly more than the Moderate Scenario as it would consist of greater density
development and increased pedestrian and bicycle traffic. Nonetheless, impacts to public views and the
surrounding environment would be less than significant.
Depending on the parcel/region of the Project area, the views of the Little San Bernardino, Santa Rosa, and
San Jacinto mountains may differ. Views of these mountain ranges may be partially blocked/impeded by
the new development along the corridor. The Municipal Code of the City includes standards for
development to protect the aesthetic quality of the City, while providing reasonable opportunities for
businesses and commercial development (City of La Quinta, 2022). The Project would comply with the City
of La Quinta General Plan and Municipal Code as it relates to the surrounding aesthetic and sense of
community. The Specific Plan aims to improve the look and feel of the Highway 111 Corridor by
redeveloping big -box retail stores with a more livable and walkable multi -use community, as appropriate. In
doing so, future development along the Highway 111 Corridor would better align with the principles of the
City's General Plan Open Space (OS) Goal OS-3: Preservation of scenic resources as vital contributors to
the City's economic health and overall quality of life (City of La Quinta, 2022). Although the redevelopment
of the Highway 111 Corridor may result in changes to the current aesthetic of the region (e.g., big -box retail,
large asphalt parking lots), impacts are anticipated to improve the function of the corridor and overall
community quality of life. Impacts are anticipated to be less than significant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-2
Environmental Analysis — Aesthetics
b) Substantially damage scenic resources, including, but not limited to, trees, rock
outcroppings, and historic buildings within a state scenic highway?
No Impact: The proposed Project area is the Highway 111 Corridor, which spans from approximately the
intersection of Highway 111 and Washington Street on the west end to Jefferson Street on the east. This
section of Highway 111 is not designated or eligible as a scenic resource by the California State Scenic
Highway System.
According to Caltrans, the nearest eligible State Scenic Highway is 7.4 miles west of the Project area, along
Highway 111 at the intersection of Monterey Avenue, Route 74, and Highway 111. From this point up until
Interstate 10, Highway 111 is designated "Eligible" as a State Scenic Highway. Route 74 is an Officially
Designated Scenic Highway in California. However, the proposed Project would not affect these Highways,
or enter a State Scenic Highway, nor would it interfere with or substantially damage scenic resources or
historic buildings within a State Scenic Highway. As such, no impacts to scenic resources are anticipated.
Mitigation Measures: No mitigation measures required.
c) In non -urbanized areas, substantially degrade the existing visual character or quality of
public view of the site and its surroundings? (Public Views are those that are experienced
from publicly accessible vantage point). If the project is in an urbanized area, would the
project conflict with applicable zoning and other regulations governing scenic quality?
No Impact: The area surrounding Highway 111 relevant to the Specific Plan is already an urbanized
environment. Proposed development scenarios do not conflict with the applicable zoning designation and
regulations. In the Land Use Element of the General Plan, the Highway 111 Corridor is encouraged to
become a mixed -use overlay district as defined in the City's Municipal Code (City of La Quinta, 2024a). The
purpose of a mixed -use (MU) area is to provide opportunities for multifamily residential development in
combination with commercial and/or office development in a cohesive and integrated manner (City of La
Quinta, 2024a). The Specific Plan would encourage and implement this and there is no conflict with
applicable zoning and regulations governing scenic quality, therefore no impact.
Mitigation Measures: No mitigation measures required.
d) Create a new source of substantial light or glare which would adversely affect day or
nighttime views in the area?
Less than Significant Impact: The proposed Specific Plan area development is intended to transform the
current landscape, dominated by big -box retail and expansive asphalt parking lots, into a vibrant, well-
connected urban space. This is designed to optimize land use by incorporating a diverse mix of upgraded
retail options and dining, moving away from the one-dimensional shopping experience currently offered.
The proposed Specific Plan area development, while introducing new sources of daytime glare and
nighttime illumination, is carefully designed to enhance views, rather than expand the amount of light
pollution. This development strategy focuses on utilizing lighting technologies that are energy -efficient
and/or designed to minimize unnecessary glare. Future development facilitated by the Specific Plan may
include low -impact lighting fixtures and reflective surfaces that are designed to reduce brightness, which
would enhance visual comfort and safety without contributing to light pollution. This approach ensures that
lighting serves both functional and decorative purposes, enriching the City's character at night and
improving navigability and security for the community.
City of La Quinta Highway 111 Corridor Specific Plan 3-3
Environmental Analysis — Aesthetics
Furthermore, future development would adhere to the policies and regulations outlined in the General Plan
as well as the City Municipal Code. Policy LU-2.3 in the Land Use Element of the General Plan states that
the City's outdoor lighting ordinance would be maintained. Section 9.100.150, Outdoor Lighting of the City's
Municipal Code, states that its purpose is to set the standards for allowing adequate energy efficient lighting
for public safety while minimizing adverse effects (City of La Quinta, 2022). Complying with the designated
policies would require that new light sources introduced along the Highway 111 Corridor be appropriately
shielded and directed away from open viewing spaces. This ensures that day and nighttime views are not
negatively impacted by the presence of these lights. By complying with these guidelines, the potential
impacts associated with light and glare can be minimized to a level that is deemed insignificant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-4
Environmental Analysis — Agriculture and Forest Resources
3.2 Agriculture and Forest Resources
Would the project:
a) Convert Prime Farmland, Unique Farmland, or
Farmland of Statewide Importance (Farmland),
as shown on the maps prepared pursuant to
the Farmland Mapping and Monitoring Program
of the California Resources Agency, to
non-agricultural use?
b) Conflict with existing zoning for agricultural use,
or a Williamson Act contract?
c) Conflict with existing zoning for, or cause
rezoning of, forest land (as defined in Public
Resources Code section 12220(g)), timberland
(as defined by Public Resources Code section
4526), or timberland zoned Timberland
Production (as defined by Government Code
section 51104(g))?
d) Result in the loss of forest land or conversion of
forest land to non -forest use?
e) Involve other changes in the existing
environment which, due to their location or
nature, could result in conversion of Farmland,
to non-agricultural use or conversion of forest
land to non -forest use?
J
J
The project area is situated within a highly urbanized section of the City, devoid of agricultural or forest
activities. Given its urban character, the area was not included in the Farmland Mapping and Monitoring
Program's surveys (California DOC, 2022). This section of the City comprises several zoning districts, all of
which exclude agricultural or forestry operations. The area is largely categorized as Urban and Built -Up
Land. Agricultural activities are not proposed as part of the Specific Plan development.
a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland),
as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program
of the California Resources Agency, to non-agricultural use?
No Impact: The area covered by the proposed Specific Plan is considered Urban and Built-up Land
according to the California Department of Conservation (DOC), Important Farmland Finder (California DOC,
2024b). Urban and Built -Up land refers to areas that are covered by structures and buildings with a
relatively high concentration. This is typically defined as having a building density of at least one (1) unit per
one and a half (1.5) acres of land, or approximately six (6) structures for every ten (10) acre parcel
(California DOC, 2024b). Prime Farmland is located adjacent to the Project area in two locations: northwest
of the West Gateway area; and southeast of the Dune Palms and Jefferson South area (California DOC,
2022). Proposed development under this Specific Plan would not enter these Prime Farmland areas and
both the West Gateway and the Dune Palms and Jefferson South areas are separated from Prime
Farmland by Washington Street at the northwest portion of the Project area and by Jefferson Street at the
City of La Quinta Highway 111 Corridor Specific Plan 3-5
Environmental Analysis — Agriculture and Forest Resources
southeast, respectfully. Furthermore, designated land uses within the Project area do not include
agricultural uses and the Project implementation would not result in conversion of existing farmland to non-
agricultural uses. Therefore, the Project does not affect an agricultural resource area and thus does not
impact designated Prime Farmland, Unique Farmland, or Farmland of Statewide Importance.
Mitigation Measures: No mitigation measures required.
b) Conflict with existing zoning for agricultural use, or a Williamson Act contract?
No Impact: As per the City of La Quinta Municipal Zoning Code, the Project area outlined in this Specific
Plan is not zoned for agricultural uses (City of La Quinta, 2024a). Therefore, the proposed Project would not
conflict with any lands zoned for agriculture uses. Additionally, the Project area is not under a Williamson
Act Contract; therefore, no impacts to Williamson Act contract lands are anticipated.
Mitigation Measures: No mitigation measures required.
c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public
Resources Code section 12220(g)), timberland (as defined by Public Resources Code section
4526), or timberland zoned Timberland Production (as defined by Government Code section
51104(g))?
No Impact: There are no anticipated changes to zoning of forest land, timberland, or timberland zoned
Timberland Production under the proposed Specific Plan. No Impact would occur.
Mitigation Measures: No mitigation measures required.
d) Result in the loss of forest land or conversion of forest land to non -forest use?
No Impact: The area covered under the Specific Plan does not contain forest land resources. Therefore,
development under the proposed Specific Plan would not result in the loss of forest land. No impact would
occu r.
Mitigation Measures: No mitigation measures required.
e) Involve other changes in the existing environment which, due to their location or nature,
could result in conversion of Farmland, to non-agricultural use or conversion of forest land
to non -forest use?
No Impact: The proposed developments outlined in the Specific Plan are designated to occur within the
specified area along Highway 111, stretching from approximately Jefferson Street to Washington Street in
La Quinta. These developments would not result in the conversion of any onsite or offsite farmland or forest
land to non-agricultural or non -forest uses. As such, there would be no impact.
Mitigation Measures: No mitigation measures required.

Environmental Analysis — Air Quality
3.3 Air Quality
Where available, the significance criteria established by the applicable air quality management district or air
pollution control district may be relied upon to make the following determinations. Would the project:
a) Conflict with or obstruct implementation of the
applicable air quality plan?
b) Result in a cumulatively considerable net
increase in any criteria pollutant for which the
project region is non -attainment under an
applicable federal or state ambient air quality
standard?
c) Expose sensitive receptors to substantial
pollutant concentrations?
d) Result in other emissions (such as those leading
to odors) adversely affecting a substantial
number of people?

The Project area is located within the Coachella Valley planning area of the Salton Sea Air Basin (SSAB)
and under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The SSAB
portion of Riverside County is currently designated as nonattainment for the federal and state ambient air
quality standards for ozone and PM1o. The Project area is designated as attainment or unclassified for all
other federal and state ambient air quality standards.
As described in Section 1, Project Information, the Project is consistent with the City's current 2035 General
Plan. Therefore, growth parameters, such as population and vehicle activity, are consistent with the
General Plan and have been previously analyzed in the certified General Plan EIR. The following General
Plan Air Quality policies and programs are applicable to and would be implemented by project:
Policy AQ-1.3: Work to reduce emissions from mobile sources by encouraging a decrease in the
number of vehicle trips and vehicle miles traveled.
— Program AQ-1.3.b: Encourage public and private schools to establish alternative transportation
programs for students.
— Program AQ-1.3.c: Adopt and implement a Transportation Demand Management Ordinance for
businesses with 50 or more employees.
— Program AQ-1.3.d: Expand routes for golf carts and other neighborhood electric vehicles and
plan for access and recharging facilities at retail, recreational, and community centers.
— Program AQ-1.3.e: Expand pedestrian and bicycle routes and provide safe and convenient
access to retail, recreational, and community centers.
— Program AQ-1.3.f.- Facilitate mixed use development concepts in specific identified areas of the
community to allow the combination of residential and non ---residential uses, such as live---
work---shop designs, as described in the Land Use Element.
— Program AQ-1.3.g: Where permitted by the Land Use plan, and where appropriate, encourage
high density residential development within walking distance to commercial, educational and
recreational opportunities.
City of La Quinta Highway 111 Corridor Specific Plan 3-7
Environmental Analysis — Air Quality
Policy AQ-1.4: Protect people and sites that are especially sensitive to airborne pollutants
(sensitive receptors) from polluting point sources.
— Program AQ-1.4.a: Uses such as manufacturing, auto body shops, and other point source
polluters should be reasonably separated from sensitive receptors.
Policy AQ-1.5: Ensure all construction activities minimize emissions of all air quality pollutants.
— Program AQ-1.5.a: All grading and ground disturbance activities shall adhere to established
fugitive dust criteria.
— Program AQ-1.5.b: Fugitive Dust Control Plans shall be reviewed and approved for
development projects.
Policy AQ-1.6: Proposed development air quality emissions of criteria pollutants shall be analyzed
under CEQA.
The impact analysis in this section is based on understanding that the population and jobs growth
anticipated under the Project is consistent with, and would not be in excess of, that anticipated by the City's
General Plan and as analyzed within the General Plan's certified EIR.
a) Conflict with or obstruct implementation of the applicable air quality plan?
No Impact: The SCAQMD has adopted multiple Air Quality Management Plans (AQMPs) to address state
and federal ambient air quality standards. Current AQMPs include:
2016 AQMP. The 2016 AQMP addresses the multiple ozone and PM2.5 standards.
2022 AQMP. The 2022 AQMP is focused on attaining the 2015 8-hour ozone standard.
2023 Coachella Valley PM,o State Implementation Plan.
According to the SCAQMD's CEQA Air Quality Handbook, the purpose of the consistency finding is to
determine if a project is inconsistent with the assumptions and objectives of the regional air quality plans,
and if it would interfere with the region's ability to comply with federal and state Ambient Air Quality
Standards (AAQS). Growth assumptions within the AQMP are based on growth assumptions and land use
designations included within local general plans. The SCAQMD's CEQA Air Quality Handbook contains the
following two key indicators of consistency with the AQMP:
1. Whether the project will not result in an increase in the frequency or severity of existing air quality
violations or cause or contribute to new violations or delay timely attainment of air quality standards or
the interim emission reductions specified in the AQMP.
2. If a project is consistent with the growth assumptions in the AQMP.
The first criterion is assessed in Impact c) below. As demonstrated in the analysis for Impact c), the
Project's potential to expose sensitive receptors to substantial air pollutant concentrations (i.e., generate
pollutant concentrations that would exceed an air quality standard) would be reduced to less than significant
with implementation of Mitigation Measure AIR-1. Therefore, the project is consistent with the first criterion.
Under the second criterion, the SCAQMD recommends that lead agencies demonstrate that a project would
not directly obstruct implementation of an applicable air quality plan and that a project be consistent with the
assumptions (typically land -use related, such as resultant employment or residential units) upon which the
air quality plan is based. The project is consistent with the City's adopted General Plan, which was adopted
in 2013, prior to the development of all the applicable AQMPs. The growth supported by development of the
Project would be consistent with the applicable General Plan, and the current General Plan was adopted
City of La Quinta Highway 111 Corridor Specific Plan 3-8
Environmental Analysis — Air Quality
prior to the current AQMP. Therefore, growth supported by the Project is accounted for in the AQMP. The
project is less than significant under this criterion.
As demonstrated above, the project would be consistent with both analysis criteria and, therefore, would not
conflict with the applicable AQMPs. The project would result in no impact.
Mitigation Measures: No mitigation measures required.
b) Result in a cumulatively considerable net increase in any criteria pollutant for which the
project region is non -attainment under an applicable federal or state ambient air quality
standard?
No Impact: As described above, the SSAB portion of Riverside County is currently designated as
nonattainment for the federal and state ambient air quality standards for ozone and PM1o.
The SCAQMD had adopted recommended air quality significance thresholds for project construction and
operation; however, these thresholds are applicable to the project level. Plan -level documents, such as the
proposed La Quinta Highway 111 Corridor Specific Plan, where no specific development is identified or
proposed and for which a construction schedule is not proposed, are not directly applicable to a plan -level
action. The Project is consistent with the General Plan and the General Plan's certified EIR. As described in
Impact a) above, the growth assumptions in the General Plan are accounted for in the applicable AQMPs.
The AQMPs demonstrate the path to attainment of the relevant air quality attainment standards. As the
Project is consistent with the General Plan, and the General Plan growth assumptions are incorporated in
and accounted for in the AQMPs, the growth that would occur within the Specific Plan area would not result
in a cumulatively considerable net increase in any criteria pollutant for which the Project region is
nonattainment.
This Specific Plan would provide a comprehensive development approach for Highway 111 focused on
public connectivity, mixed -use development, and enhanced transportation options. This Specific Plan
includes introduction of mixed -use development, integration of pedestrian -friendly pathways and dedicated
bike lanes, and other improvements to connectivity and accessibility. The project impact would be less than
significant.
Mitigation Measures: No mitigation measures required
c) Expose sensitive receptors to substantial pollutant concentrations?
Less Than Significant with Mitigation Incorporated: Sensitive receptors are defined as facilities or land
uses that include members of the population that are particularly sensitive to the effects of air pollutants,
such as children, the elderly, and people with illnesses. Examples of these sensitive receptors are
residences, schools, hospitals, and daycare centers. The California Air Resources Board (CARB) has
identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over
65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as
asthma, emphysema, and bronchitis.
Sensitive receptors near the area include the residences north, east, south, and west of the Project. Amelia
Earhart Elementary and John Glenn Middle School are adjacent to each other, about 1.5 miles north of the
proposed Project area, while La Quinta High School is located north of the Project area along the
Whitewater River. Additionally, James Madison Elementary School is located about 1.6 miles northeast of
the Specific Plan area.
City of La Quinta Highway 111 Corridor Specific Plan 3-9
Environmental Analysis — Air Quality
Localized Significance Thresholds
Localized Significance Thresholds (LSTs) were developed in response to SCAQMD Governing Boards'
Environmental Justice Enhancement Initiative (1-4). The SCAQMD provided the Final Localized Significance
Threshold Methodology (dated June 2003 [revised 2008]) for guidance (SCAQMD, 2008). The LST
methodology assists lead agencies in analyzing localized air quality impacts. The SCAQMD provides the
LST screening lookup tables for one, two, and 5-acre sites for the following pollutants: CO, NOX, PM2.5, and
PM1o. The LST methodology and associated mass rates are not designed to evaluate localized impacts
from mobile sources traveling over the roadways. The SCAQMD recommends that any project over 5 acres
should perform air quality dispersion modeling to assess impacts to nearby sensitive receptors. The Project
is located within Sensitive Receptor Area (SRA) 30, CV.
The SCAQMD LST methodology provides two approaches for performing the LST analysis. For projects of
5 acres or less where emissions would occur, the SCAQMD has developed a series of look up tables that
provide estimates of daily construction or operational emissions above which a project's emissions are
determined to have a significant air quality impact. These emission LSTs are provided for each
combination of pollutants (CO, NO2, PM1o, and PM2.5), SRA, size of the project emission area, and distance
to the nearest sensitive receptor. For projects where emissions occur over an area larger than 5 acres, the
localized significance impacts for construction and operation emissions can be derived by either applying
the LSTs for a 5-acre area, or by performing air dispersion modeling. Thus, the primary determinants for
the LST assessment, therefore, are the SRA where the project is located, the size of the emission area, and
distance to the nearest sensitive receptor.
The Specific Plan is a guidance -level document and does not include site -specific development plans.
Mitigation Measure AIR-1 is proposed to reduce the potential impact of future development to less than
significant. With implementation of Mitigation Measure AIR-1, future development supported by the
Specific Plan would not generate a significant localized impact.
Mitigation Measures: AIR-1
d) Result in other emissions (such as those leading to odors) adversely affecting a substantial
number of people?
No Impact: The SCAQMD recommends that odor impacts be addressed in a qualitative manner. Such an
analysis shall determine whether the project would result in excessive nuisance odors, as defined under the
California Code of Regulations and Section 41700 of the California Health and Safety Code and thus would
constitute a public nuisance related to air quality.
Land uses typically considered associated with odors include wastewater treatment facilities, waste -
disposal facilities, or agricultural operations. The Specific Plan area would not contain land uses typically
associated with emitting objectionable odors. Future development supported by the Project would involve
the use of diesel construction equipment and diesel trucks during construction. However, the Project area
has a predominance of commercial land uses and emissions from trucks are common throughout the
project vicinity. In addition, project -generated emissions would rapidly disperse in the atmosphere and
would not be noticeable to the nearby public. Therefore, the project would not generate a significant odor
impact during construction or operation.
Mitigation Measures: No mitigation measures required.

The potential for sensitive biological resources to occur (federally or state listed or state special status
plants and wildlife, Sensitive Natural Communities (SNCs), and wetlands) were evaluated within the areas
planned for development within the Project area, as well as a 100-foot buffer around the Project area for
potential wildlife impacts. The Project area comprises seven DSAs, as outlined in Table 1.1 and Figure 1-2,
which are planned to be developed with various focuses in mind and differ among each distinct area.
The following information is based on the Biological Reconnaissance Technical Memorandum (Appendix B)
that was prepared in support of the proposed La Quinta Highway 111 Specific Plan. The technical
memorandum documents the results of a site visit conducted on February 4, 2023 that covered the Project
area and the 100-foot buffer. The following information is also based on the results of two protocol -level
floristic surveys that were conducted separately on April 26 through April 27, 2023, and October 24, 2023 in
one area of the Project, encompassing a 15-acre parcel embedded within the ADN DSA (Figure 1-2), and
documented in a separate Botanical Technical Memorandum (Appendix B).
City of La Quinta Highway 111 Corridor Specific Plan 3-12
Environmental Analysis — Biological Resources
The Project area with 100-foot wildlife buffer is located entirely within the City of La Quinta. Land cover is
primarily classified as developed, interspersed with shrub/scrub (USGS, 2016). The 100-foot wildlife buffer
extends into the Whitewater River Watershed. The Project area is bordered by the Whitewater River to the
north and is bisected by Highway 111. The landscape surrounding the Project area is highly urbanized and
developed, with high amounts of vehicular traffic.
There are seven areas planned for development with various focuses ( Table 1.1; Figure 1-2). Depending
on the parcel/region proposed for development within the Project area, there are two scenarios that are
being assessed: a Moderate Scenario, which would utilize lower density development, and a Max Scenario,
which would utilize higher density development. In all cases of potential impact, the "high" scenario would
consist of increased pedestrian and bicycle traffic, which may result in slightly higher impacts to potential
sensitive resources in those areas. The areas planned for development are surrounded by commercial
businesses, residential areas, and roadways. A few areas planned for development within ADN, DJN, and
DJS contain variable extents of natural habitat (Figure 1-2 through Figure 1-4). The DJS area contains only
marginally suitable habitat features due to the limited extent of land and closer proximity to commercial
buildings and roads. The other areas planned for development within WAN, ADS, and WAS have been
graded or altered from their natural state and generally have less potential to support sensitive biological
resources.
Although the Project area is within a developed landscape, there are shrubs and dune habitat within select
areas (WG, ADN, DJN, and DJS) that may support special status species and do support common species.
Within the more natural areas, small mammal burrows were observed within the Project area, which can be
used by other taxa such as birds and reptiles. The Project area and 100-foot wildlife buffer also supports
common avian species protected by the federal Migratory Bird Treaty Act (MBTA) and California Fish and
Game Code (FGC). A brief summary of each area planned for development is included below, oriented
from west to east, and north to south.
3.4.1 West Gateway
The WG Development Area has minimal trees and shrubs, with limited vegetation overall. It includes Point
Happy, an undeveloped elevated area (183 feet) bordered by Highway 111 to the south, Whitewater River
to the north, and businesses and restaurants to the east and west. While special status species are not
expected, nesting birds may be present.
3.4.2 Washington and Adams North
The areas proposed for development within the WAN Development Area have no trees or shrubs present.
They have limited vegetation within them and are surrounded by commercial businesses and concrete
parking lots. Special status species are not expected to occur here.
3.4.3 Washington and Adams South
The areas proposed for development within the WAS Development Area are clustered at the southern edge
bordering Avenue 47. These areas consist of a movie theatre and paved parking lot bordered by a small
margin of open space that has already been graded and has fences around it. There are trees along the
edges of the areas proposed for development, and roads. Special status species are not expected to occur
here, but nesting birds may occur.
3.4.4 Adams and Dune Palms North
The area proposed for development within the ADN Development Area is a 15-acre parcel that contains
natural habitat features that may support sensitive species and does support common species as well as
City of La Quinta Highway 111 Corridor Specific Plan 3-13
Environmental Analysis — Biological Resources
nesting birds. Trees and shrubs are present. A separate report for this area has been prepared by GHD
(Appendix B). The parcel is bordered by commercial development and concrete parking lots.
3.4.5 Adams and Dune Palms South
The areas proposed for development within the ADS Development Area are clustered at the southwest
corner and bordered by two major roads, with a discrete and disjointed area at the east edge within an
already paved parking lot and also bordered by a major road. The areas proposed for development are
already graded, and there are trees and shrubs present along the edges and roads, some or all planted.
Special status species are not expected to occur here, but nesting birds may occur.
3.4.6 Dune Palms and Jefferson North
The area proposed for development within the DJN Development Area is at the westernmost edge, and
contains natural habitat features that may support sensitive species and does support common species as
well as nesting birds.
3.4.7 Dune Palms and Jefferson South
The area proposed for development within the DJS Development Area is at the northern edge and bordered
by Highway 111. This area is already paved on the east side. It contains marginal amounts of natural
habitat features that may support sensitive species and does support common species as well as nesting
birds.
Based on occurrence records, habitat availability, and the protocol -level site visit of the ADN Development
Area (Figure 1-2), and the reconnaissance -level site visit of the entire Project area, special status plants do
not have potential to occur in areas of the Project that are proposed for development. No special status
plants or SNCs were observed during surveys of the ADN Development Area or within the greater Project
area. Based on occurrence records, habitat availability, and the reconnaissance -level site visit of the entire
Project area, special status wildlife species have a potential to occur. The Project area is bordered to the
north by the channelized Whitewater River. No flowing water and minimal moisture within the riverbed was
observed. In addition, there is the Deep Canyon Stormwater Channel that bisects a small portion of the
northwest corner of the Project area. No impacts to jurisdictional wetlands or waters, or SNCs, are
expected.
a) Have a substantial adverse effect, either directly or through habitat modifications, on any
species identified as a candidate, sensitive, or special -status species in local or regional
plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish
and Wildlife Service?
Special -status Plant Species
Less than Significant Impact with Mitigation Incorporated: The database scoping detailed in the
botanical technical memorandum (Appendix B) produced a total of 66 plant species known to occur in the
nine USGS quads within and surrounding the Project area. Based on species -specific habitat requirements
and habitat availability within the Project area, three species were determined to have a low potential to
occur, and seven to have a moderate potential to occur (Table 3.1) based on the results of database
scoping.
The majority of areas planned for development in the Project area are already developed and do not have
potential for any special status plant species to occur. Three parcels in the Project area are undeveloped,
retain natural habitat, and have potential for special status plants to occur: ADN, DJN, and DJS; however,
City of La Quinta Highway 111 Corridor Specific Plan 3-14
Environmental Analysis — Biological Resources
no special status plant species were observed during protocol -level surveys of the ADN Development Area
in May and October of 2023, or in the reconnaissance survey of the entire Project area.
Desert plant communities can be ephemeral in nature given the variable precipitation of any given year and
species adaptations to this variability is resource availability. While the potential for sensitive plant species
to be present in the undeveloped spaces of the Project area is generally low, the suitability of these sites to
host sensitive species in subsequent years may change. With incorporation of Measure BIO-1 and 13I0-2,
the Project would have a less than significant impact on special status plant species.
Special -status Wildlife Species
Less than Significant with Mitigation Incorporated: The database scoping detailed in the biological
resources technical memorandum (Appendix B) returned a total of 87 species (Table 3.2). The potential for
sensitive wildlife species to occur was determined based on existing data and the reconnaissance level site
visit (Appendix B). Special status species are federally and/or state listed, a California Department of Fish
and Wildlife (CDFW) Species of Special Concern, CDFW Fully Protected, on the CDFW Special Animals
List, or any combination of these.
The majority of areas planned for development within the Project area (within WAN, WAS, and ADS
Development Areas) are developed and do not have potential for any special status wildlife species to
occur. However, common and urban adapted bird species protected by the FGC and MBTA may occur if
structures are present, or nesting features (such as shrubs and trees) are present within or adjacent to the
areas. Based on the reconnaissance -level site visit on February 4, 2023 and review of existing data, the
ADN, DJN, and DJS areas within the Project area may provide suitable habitat for special status wildlife
species and do support common species protected by the MBTA and FGC. However, habitat within DJS is
less suitable than the other two areas. The areas within the WAN, WAS, and ADS may also support
common and urban adapted bird species protected by the MBTA and FGC.
Three areas planned for development within the Project area contain discrete areas that are undeveloped,
retain natural habitat, and have potential for special status wildlife to occur, in addition to common bird
species protected by the FGC and MBTA: ADN, DJN, and DJS, for which the following species may occur:
• The Palm Springs Round -tailed Ground Squirrel (Xerospermophilus tereticaudus chlorusa; CDFW
Species of Special Concern) has a moderate potential to occur at all three Development Areas
(ADN, DJN, and DJS).
• The Burrowing Owl (Athene cunicularia; CDFW Species of Special Concern) has a moderate
potential to occur within ADN.
• The Coachella Valley Fringe -toed Lizard (Uma inornata; federally threatened and state
endangered) is a reptile species with a moderate potential to occur within ADN Development Area.
• Flat -tailed Horned Lizard (Phrynosoma mcallii; CDFW Species of Special Concern) is a reptile
species with a moderate potential to occur within ADN and DJN.
• Coachella Giant Sand Treader Cricket (Macrobaenetes valgum; CDFW Special Animals List) is an
insect with a moderate potential to occur at ADN and DJN.
• The Costa's Hummingbird (Calypte costae; CDFW Special Animals List), Abert's Towee (Pipilo
aberti; CDFW Special Animals List), Cooper's Hawk (Accipiter cooperii; CDWF Watch List), and
Vermillion Flycatcher (Pyrocephalus obscurus; CDFW Species of Special Concern) have a
moderate potential to occur at all three Development Areas (ADN, DJN, and DJS).
• The Black -tailed Gnatcatcher (Polioptila melanura; CDFW Watch List) has a moderate potential to
occur at ADN and DJN.
City of La Quinta Highway 111 Corridor Specific Plan 3-15
Environmental Analysis — Biological Resources
The Palm Springs Round -tailed Ground Squirrel, Burrowing Owl, Coachella Valley Fringe -toed
Lizard, Flat -tailed Horned Lizard, and Coachella Giant Sand Treader Cricket are species covered
by the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP). The Burrowing
Owl is a covered species under the CVMSHCP but is afforded additional protections under FGC
and the MBTA and would require additional minimization measures. According to the CVMSHCP,
authorization of take for all species with a moderate potential to occur, except the six bird species,
can be obtained through compliance with the CVMSHCP and the Local Development Mitigation
Fee (LDMF) paid to the Coachella Valley Conservation Commission (CVCC, 2023).
All Conservation Measures that are applicable within Section 4.4 (Required Avoidance, Minimization, and
Mitigation Measures) and Section 9 (Species Accounts and Conservation Measures) of the CVMSHCP
should be implemented by the Project to minimize impacts to plant and wildlife species within the Habitat
Conservation Plan's (HCP's) jurisdiction (CVMSHCP, 2016). Assuming there would be compliance with the
CVMSHCP and with incorporation of Mitigation Measure 113I0-1 through 13I0-5, potential impact to the five
species covered by the CVMSHCP would be less than significant.
Based on existing habitat and available data, certain areas (ADN, DJN, and DJS) may support special
status species and do support common species. Though, the area in DJS contains less suitable habitat and
extent than the other two areas. The entire Project area may support migratory and nesting birds.
With inclusion of Mitigation Measures 1131O-1, 113I0-2, 113I0-3, 1131O-4, and 1131O-5 impacts to special status
wildlife species, including native, migratory, and nesting birds not covered by the CVMSHCP, would be less
than significant.
The Project area does not overlap any federally designated critical habitat (USFWS, 2023a). No impact
would result.
With implementation of Mitigation Measures BIO-1, 113I0-2, 113I0-3, 131O-4, and 1131O-5 impacts to protected
wildlife species would be less than significant.
Mitigation Measures: BIO-1, BIO-2, BIO-3, BIO-4, and BIO-5.
b) Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations or by the California
Department of Fish and Game or US Fish and Wildlife Service?
Less than Significant Impact with Mitigation Incorporated: A query of the California Natural Diversity
Database (CNDDB) (CDFW, 2023a) returned multiple locations of Desert Fan Palm Oasis Woodland
(Washingtonia filifera) SNC (G3, S3.2) in the nine quads surrounding the Project area; however, the nearest
Desert Fan Palm Oasis to the Project area is over five miles to the northeast. No native fan palms are
present in the Project area. The undeveloped portions of the Project area are vegetated by Creosote Bush
Scrub (Larrea tridentata), a natural community that is not considered sensitive by CDFW (G5, S5). The
Project would not impact any SNCs, as none are present.
A small portion of DPJ Development Area is mapped as "stabilized shielded desert sand fields" per the
CVMSHCP's natural community characterization and mapping (CVCC, 2024); however, this area is not
within a designated conservation area and, therefore, is not an identified priority area for conservation per
Section 10.2.6 of the CVMSHCP (CVMSHCP, 2016). The Project would not impact natural communities
identified for conservation as described in the CVMSHCP.
The Whitewater River borders the northern edge of the Project area; however, the river has been
channelized, and the banks are cemented at the upslope edge. There was no riparian vegetation observed
along the length of the corridor within the Project area. This Specific Plan is not expected to affect riparian
City of La Quinta Highway 111 Corridor Specific Plan 3-16
Environmental Analysis — Biological Resources
habitat or other sensitive natural communities, as it is a planning -level document. However, future
development in the Highway 111 corridor could potentially impact the flow or banks of the nearby
Whitewater River. Consequently, future projects should incorporate Mitigation Measure 1131O-6 to minimize
potential impacts on the natural flow of streams or rivers.
Mitigation Measures: 131O-6.
c) Have a substantial adverse effect on state or federally protected wetlands (including, but not
limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological
interruption, or other means?
No Impact: No wetlands are documented in the Project area based on database searches (National
Wetlands Inventory [NWI]) (USFWS, 2023b), and none were observed in the Project area at the time of
surveys.
The Whitewater River is along northern border of the Project area. The section of river adjacent to a
majority of the Project area is classified as either a riverine intermittent streambed that is intermittently
flooded or a riverine unknown perennial with unconsolidated bottom that is semi -permanently flooded
(USFWS, 2023b). There is a small section of the Whitewater River that is within the Project area within the
DJN Development Area, but the river is also channelized in this section, with steep, bare slopes and
intermittently ponded water (not flowing). The Project is not expected to have an impact on state or federally
protected wetlands.
Mitigation Measures: No mitigation measures required.
d) Interfere substantially with the movement of any native resident or migratory fish or wildlife
species or with established native resident or migratory wildlife corridors, or impede the use
of native wildlife nursery sites?
No Impact: Wildlife corridors refer to established migration routes commonly used by resident and
migratory species for passage from one geographic location to another. Maintaining the continuity of
established wildlife corridors is important to: a) sustain species with specific foraging requirements, b)
preserve a species' distribution potential, and c) retain diversity among many wildlife populations.
The Project is approximately seven miles from the nearest "essential connectivity area" and one mile from a
"natural landscape block" and "small natural landscape area" identified by the California Habitat
Connectivity Project (CDFW, 2023c). The Project area is surrounded by existing development, Highway
111, and the highly modified Whitewater River. Habitat in the Project area is highly fragmented. No new
barriers to terrestrial wildlife movement would result from the Project, and the Project would not
substantially interfere with migratory birds, bats, or other species. Due to the level of development existing
surrounding the Project area, there would be no impact to the habitat access, connectivity, or migratory
corridors of wildlife species.
Mitigation Measures: No mitigation measures required.
e) Conflict with any local policies or ordinances protecting biological resources, such as a tree
preservation policy or ordinance?
Less than Significant Impact: The proposed Highway 111 Specific Plan does not include any site -specific
designs or proposals, nor does it grant any entitlements for development that would have the potential to
conflict with local policies or ordinances protecting biological resources. The City of La Quinta 2035 General
City of La Quinta Highway 111 Corridor Specific Plan 3-17
Environmental Analysis — Biological Resources
Plan (City of La Quinta, 2022) addresses natural resources within the City limits through its Biological
Resources Element. The goals, policies, and programs within this Element address the preservation of
valuable habitat and species which occur in the City and align with federal, state, and regional efforts
toward preservation. The City does not have an adopted tree ordinance.
Future development proposed to implement the Specific Plan would be required to comply with all
applicable policies included in the General Plan. Therefore, this impact would be less than significant.
Mitigation Measures: No mitigation measures required.
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community
Conservation Plan, or other approved local, regional, or state habitat conservation plan?
Less Than Significant Impact with Mitigation Incorporated: Habitat Conservation Plans (HCPs) and
Natural Community Conservation Plans (NCCPs) are site -specific plans to address effects on sensitive
species of plants and animals. The Project area is within the CVMSHCP (CVMSHCP, 2016), which is an
HCP and NCCP implemented by the CVCC (CDFW, 2023b; CVCC, 2023). The City of La Quinta has been
a participant in the CVMSHCP since 1996. If the project qualifies, the signatories to the CVMSHCP are able
to obtain coverage for incidental take for the 21 wildlife and plant species that the CVMSHCP covers
(CVCC, 2023).
The proposed Project area is urbanized and highly developed and is not located within any CVMSHCP
identified Conservation Areas; however, the westernmost extent of the Project area is less than one mile
east of a portion of the Santa Rosa and San Jacinto Mountains Conservation Area boundary (CVCC, 2024).
The plant species covered by the CVMSHP include the Coachella Valley milkvetch (Astragalus lentiginosus
var. coachellae), triple -ribbed milkvetch (Astragalus tricarinatus), Little San Bernardino Mountains linanthus
(Linanthus maculatus), Mecca aster (Xylorhiza cognata), and Orocopia sage (Salvia greatae). None of
these species have potential to occur in the Project area due to a lack of suitable habitat or a suitable
elevational range.
Wildlife species covered by the CVMSHCP that have a moderate potential to occur include Palm Springs
Round -tailed Ground Squirrel, Burrowing Owl, Flat -tailed Horned Lizard, Coachella Valley Fringe -tailed
Lizard, and the Coachella Giant Sand Treader Cricket (CDFW, 2023b).
With implementation of Mitigation Measure 13I0-7, the Project would not conflict with the provisions of an
adopted HCP/NCCP and, therefore, would have a less than significant impact.
Mitigation Measures: BIO-7
Biological Resources Mitigation Measures
• 13I0-1: Assessment of Biological Resources and Worker Environmental Awareness
Training
Prior to Project construction activities for all projects covered in this IS/MND, a complete and recent
inventory of rare, threatened, endangered, and other sensitive species located within the Project
footprint and within offsite areas with the potential to be affected, including California Species of
Special Concern and California Fully Protected Species (Fish and Game Code § 3511), will be
completed. Species to be addressed should include all those which meet the CEQA definition
(CEQA Guidelines § 15380). The inventory should address seasonal variations in use of the Project
area and should not be limited to resident species. Focused species -specific surveys, completed by
a qualified biologist and conducted at the appropriate time of year and time of day when the
City of La Quinta Highway 111 Corridor Specific Plan 3-18
Environmental Analysis — Biological Resources
sensitive species are active or otherwise identifiable are required. Acceptable species -specific
survey procedures should be developed in consultation with CDFW and the U.S. Fish and Wildlife
Service, where necessary. Note that CDFW generally considers biological field assessments for
wildlife to be valid for a one-year period, and assessments for rare plants may be considered valid
for a period of up to three years. Some aspects of the proposed Project may warrant periodic
updated surveys for certain sensitive taxa, particularly if the Project is proposed to occur over a
protracted time frame, or in phases, or if surveys are completed during periods of drought.
An environmental training program should be developed and presented by a qualified biologist to all
crew members prior to the beginning of all Project construction in natural areas planned for
development. The training should describe special -status plant and wildlife species and sensitive
habitats that could occur within the Project area, protection afforded to these species and habitats,
and avoidance and minimization measures required to avoid and/or minimize impacts from the
project.
All new construction personnel should receive this training before beginning work on this Project. A
copy of the training and training materials should be provided to construction crews for review and
approval at least 30 days prior to the start of construction. As needed, in -field training should be
provided to new on -site construction personnel by the qualified biologist or a qualified individual who
should be identified by the qualified biologist, or initial training should be recorded and replayed for
new personnel.
• 131O-2: General Measures for Plants and Wildlife
When working in the natural habitat areas, the number of access routes, number and size of staging
areas, and the total area of the activity should be limited to the minimum necessary to achieve the
project goal. Routes and boundaries outside of normal access roads should be clearly delineated
through fencing or flagging.
Food, trash, and other solid wastes should be disposed of in Common Raven proof/wildlife proof,
covered refuse containers and regularly removed from the various structures and facilities on a daily
basis to avoid offsite dispersal of waste and to avoid attracting wildlife onto the Project site.
Following covered activity work, all trash and debris should be removed from the work area.
Construction work should avoid direct destruction of burrows through chaining (dragging a heavy
chain over an area to remove shrubs), disking, cultivation, and urban, industrial, or agricultural
development.
Project -related excavations greater than 6 inches deep should be secured to prevent wildlife entry
and entrapment. Holes and trenches should be back -filled, securely covered, or fenced. Excavations
that cannot be fully secured should incorporate appropriate wildlife ramp(s) at a slope of no more
than a 3:1 ratio (horizontal: vertical, equivalent to a 33.3 percent or 18.4-degree slope), or other
means to allow trapped animals to escape.
Personnel on site should be required to check under their vehicles for sensitive species prior to
moving them and should exercise caution while driving on the Project site.
Before moving, burying, or capping, inspect for wildlife in any construction pipes, culverts, or similar
structures that are stored on the site for one or more nights. Alternatively, cap structures before
storing on the work site.
City of La Quinta Highway 111 Corridor Specific Plan 3-19
Environmental Analysis — Biological Resources
• BIO-3: Special Status and Migratory Birds
Construction should be conducted, if possible, during the fall and/or winter months and outside of
the avian nesting season (generally February 1 — August 31) to avoid any direct and or indirect
effects to protected nesting birds. Pre -construction surveys shall focus on both direct and indirect
evidence of nesting, including nest locations and nesting behavior. The qualified avian biologist will
make every effort to avoid potential nest predation as a result of survey and monitoring efforts. If
active nests are found during the pre -construction nesting bird surveys, a qualified biologist shall
establish an appropriate nest buffer to be marked on the ground. Nest buffers are species specific
and shall be at least 100 feet for passerines and 300 feet for raptors. A smaller or larger buffer may
be determined by the qualified biologist familiar with the nesting phenology of the nesting species
and based on nest and buffer monitoring results. Construction activities may not occur inside the
established buffers, which shall remain on -site until a qualified biologist determines the young have
fledged or the nest is no longer active. Active nests and adequacy of the established buffer distance
shall be monitored at least once a week or as needed by the qualified biologist until the qualified
biologist has determined the young have fledged or the Project has been completed. The qualified
biologist has the authority to stop work if nesting pairs exhibit signs of disturbance.
• BIO-4: Burrowing Owl Habitat Assessment and Focused and Pre -Construction Surveys
No less than 60 days prior to the start of Project -related activities for all projects covered in the
MND, a burrowing owl habitat assessment shall be conducted by a qualified biologist according to
the specifications of the Staff Report on Burrowing Owl Mitigation (Department of Fish and Game,
March 2012 or most recent version) for all projects covered under the MND.
If the habitat assessment demonstrates suitable burrowing owl habitat, then focused burrowing owl
surveys shall be conducted by a qualified biologist in accordance with the Staff Report on Burrowing
Owl Mitigation (2012 or most recent version) prior to vegetation removal or ground -disturbing
activities. If burrowing owls are detected during the focused surveys, the qualified biologist and
Project proponent shall begin coordination with CDFW and USFWS immediately, and shall prepare
a Burrowing Owl Avoidance and Monitoring Plan that shall be submitted to CDFW for review and
approval prior to commencing Project activities. The Burrowing Owl Plan shall describe proposed
avoidance and monitoring actions, including measures necessary to avoid take of burrowing owl
individuals, nests, and eggs. The Burrowing Owl Plan shall include the number and location of
occupied burrow sites (occupied site means at least one burrowing owl or its sign has been
observed within the last three years; may be indicated by owl sign including feathers, pellets, prey
remains, eggshell fragments, or excrement at or near a burrow entrance or perch site), acres of
burrowing owl habitat that will be impacted, details of site monitoring, and details on proposed
buffers and other avoidance measures. If impacts to occupied burrowing owl habitat or burrow(s) or
burrowing owl individuals, nests, or eggs cannot be avoided, appropriate California Endangered
Species Act (CESA) authorization (i.e., Incidental Take Permit under Fish and Game Code section
2081) should be obtained from CDFW prior to commencement of Project activities.
Preconstruction burrowing owl surveys shall be conducted no less than 14 days prior to the start of
Project -related activities and within 24 hours prior to ground disturbance, in accordance with the
Staff Report on Burrowing Owl Mitigation (2012 or most recent version). Preconstruction surveys
should be repeated when there is a pause in construction of more than 30 days. Preconstruction
surveys should be performed by a qualified biologist following the recommendations and guidelines
provided in the Staff Report on Burrowing Owl Mitigation. If the preconstruction surveys confirm
occupied burrowing owl habitat, Project activities shall be immediately halted. The qualified biologist
City of La Quinta Highway 111 Corridor Specific Plan 3-20
Environmental Analysis — Biological Resources
shall coordinate with CDFW and prepare a Burrowing Owl Avoidance and Monitoring Plan that shall
be submitted to CDFW and USFWS for review and approval prior to commencing Project activities.
• 113I0-5: Artificial Light Impacts
Throughout construction and the lifetime operation of all projects covered in the IS/MND the City
and Project proponents shall eliminate all nonessential lighting throughout the Project area and
avoid or limit the use of artificial light at night during the hours of dawn and dusk when many wildlife
species are most active. The City and Project proponent shall ensure that all lighting for the Project
is fully shielded, cast downward and directed away from surrounding open -space and agricultural
areas, reduced in intensity to the greatest extent possible, and does not result in lighting trespass
including glare into surrounding areas or upward into the night sky (see the International Dark -Sky
Association standards at http://darksky.org/). The City and Project proponent shall ensure use of
LED lighting, proper disposal of hazardous waste, and recycling of lighting that contains toxic
compounds with a qualified recycler.
• 113I0-6: CDFW Lake and Streambed Alteration (LSA) Program
Prior to construction and issuance of any grading permit, the Project Sponsor shall obtain written
correspondence from CDFW stating that notification under Section 1602 of the Fish and Game
Code is not required for the Project, or the Project Sponsor should obtain a CDFW-executed Lake
and Streambed Alteration Agreement, authorizing impacts to Fish and Game Code Section 1602
resources associated with the Project.
• 113I0-7: Project Adherence to the CVMSHCP
All Conservation Measures that are applicable within Section 4.4 (Required Avoidance,
Minimization, and Mitigation Measures) and Section 9 (Species Accounts and Conservation
Measures) of the CVMSHCP should be implemented by the Project to minimize impacts to plant and
wildlife species within the HCP's jurisdiction (CVMSHCP, 2016).
The Project is outside of a designated Conservation Area, and a Joint Review Project is not
required. However, the LDMF to the CVCC is required for development projects. Submission of the
LDMF to the CVCC is recommended before building or grading permits are submitted.
Prior to construction and issuance of any grading permit for all projects covered in the IS/MND, the
City shall ensure compliance with the CVMSHCP and its associated Implementing Agreement and
shall ensure the collection of payment of the CVMSHCP Local Development Mitigation Fee and
transfer of fees, at least quarterly and prior to impacts to Covered Species and their Habitats, to the
Coachella Valley Conservation Commission.
Prior to vegetation removal or ground -disturbing activities, for all project areas covered in the
IS/MND that contain suitable habitat for sand -dependent Covered Species, the City will collaborate
with the Coachella Valley Conservation Commission to plan and implement a salvage of sand -
dependent Covered Species within the Project site.

Potential to Occur:
No potential: Habitat in and adjacent to the Project area is clearly unsuitable for the species requirements (cover, substrate, elevation, hydrology, plant community, site history,
disturbance regime).
Low potential: Few of the habitat components meeting the species requirements are present, and/or the majority of habitat on and adjacent to the site is unsuitable or of very poor
quality. The species is not likely to be found in the Project area.
Moderate potential: Some of the habitat components meeting the species requirements are present, and/or only some of the habitat on or adjacent to the site is unsuitable. The
species has a moderate probability of being found in the Project area.
High potential: All of the habitat components meeting the species requirements are present and/or most of the habitat on or adjacent to the site is highly suitable. The species has a
high probability of being found in the Project area.

Historic Overview
La Quinta is nestled amidst the Santa Rosa Mountains and is situated on the base of the CV. Achieving
City status on May 1, 1982, La Quinta has witnessed continuous development, particularly along the
Highway 111 Corridor, fueled by a steadily increasing population that peaks during the winter season (City
of La Quinta, 2024b). La Quinta is within the ancestral lands of the Desert Cahuilla Indians, who have
resided in the Coachella Valley since immemorial, including areas such as the Martinez Canyon area of the
CV and what is known today as Point Happy. The Desert Cahuilla Indians were hunter and gatherers and
one of the few Native American Tribes to dig wells. The area held significant importance for the Cahuilla
people due to its role as a vital access point to water sources, including the Whitewater River. Notably,
within a distance of less than 300 yards from Point Happy, a well was excavated. This well later lent its
name to the present-day City of Indian Wells (City of La Quinta, 2024b; SCTCA, 2024).
For centuries, the Cahuilla people were the sole inhabitants of the CV, maintaining a permanent presence.
It wasn't until the early 19th century that Europeans started journeying through the valley. Spanish, and
later Mexican explorers, soldiers, and missionaries arrived with the sole aim of swiftly crossing the
challenging desert terrain (La Quinta Historical Society, 2017).
Record Search
This analysis is based on a cultural records investigation conducted at the California Historical Resources
Inventory System (CHRIS) Eastern Information Center (EIC) located at the University of California,
Riverside. The examination of records took place on January 22, 2024, encompassing a review of maps,
records, and reports from the EIC pertaining to the Project area. The assessment involved a review of the
U.S. Geological Survey (USGS) 1959 La Quinta 7.5 minute series quadrangle map, 1941 Toro Peak 15
minutes series, and 1959 Palm Desert 15 minute series topographic map to assess the Project site. In
addition, the California Points of Historical Interest, California Historical Landmarks, California Register of
Historic Places, National Register of Historic Places (NRHP), the California State Historic Resources
Inventory, and historic topographic maps were reviewed.
The findings revealed that there have been 92 studies on cultural resources conducted within the
approximately 410 acres of the proposed Project area. A total of 56 cultural resource properties are
documented within the Project area boundaries. According to the NRHP, there are no listed properties
located within the bounds of the Project area. Per results from the California Office of Historic
City of La Quinta Highway 111 Corridor Specific Plan 3-51
Environmental Analysis — Cultural Resources
Preservation's (OHP's) Archaeological Resources Directory (ARD), there is one property that is listed as
considered eligible for listing on the NRHP (P-33-001178 [CA-RIV-001178] La Quinta Evac. CH. AD).
According to the CHRIS records search, California OHP Built Environment Resource Directory (BERD)
indicates that two properties are listed as historically significant by local government (P-33-007263, PT.
Happy Ranch and P-33-023955, PT. Happy Ranch) located at the intersection of Highway 111 and
Washington Street. The term "Happy Ranch" is in reference to Point Happy, which is described above. The
West Gateway area includes Point Happy, which is an undeveloped elevated area (183 feet in elevation)
bordered by Highway 111 to the south, Whitewater River to the north, and restaurants and businesses to
the east and west. Point Happy is linked to nearby culturally and historically significant resources. Any
forthcoming development within the West Gateway area should consider Point Happy. It is advisable to
consult a cultural resources expert before engaging in any ground -disturbing activities near this site.
A previous study identified two prehistoric resources (P-33-008692/CA-RIV-006190, P-33-002936/CA-RIV-
002936) within the Project area, near the intersection of Dune Palms Road and Highway 111. P-33-
008692/CA-RIV-006190 consists of a 230 meter (east/west) by 170 meter (north/south) prehistoric -era
resource with the three large and three small loci comprised of ceramics, burned bone, Iithic debitage,
burned clay, and fire -affected rock. P-33-002936/CA-RIV-002936 consists of a 150 meter (north/south) by
60 meter (east/west) prehistoric -era resource comprised of ceramics, fire -affected rock, semi -fired clay,
animal bone, and shell fragments (Hallock et al., 2023).
Given the extensive amount of documented cultural resources within the Project area, it is conceivable that
yet -to -be -discovered cultural resources exist. However, it is important to note that the densely developed
environment and established infrastructure of the Project area may mitigate the probability of encountering
such unrecorded cultural resources. Since this Specific Plan serves as a guide for future development
along the corridor, forthcoming development endeavors within the Project area should undergo thorough
assessment by a cultural resource expert to evaluate any historical, archaeological, or cultural heritage
resources that have not been recorded and to offer suggestions regarding their importance and appropriate
management before any ground -disturbing activities commence. Individuals engaged in future development
along the Highway 111 Corridor are urged to recognize and respect the significance and irreplaceable value
of cultural resources. For assistance, a comprehensive list of cultural resource consultants statewide can be
accessed online at http://chrisinfo.org. Refer to Appendix C: Cultural Resources for the non -confidential
cultural records search report.
Sacred Lands File Search
The following analysis is based on a Sacred Lands File (SLF) record search by the NAHC received on
March 8, 2024. The results of the search were negative, meaning that no specific site information was
found in the SLF search. However, it is important to note that the absence of such information in the SLF
does not necessarily indicate the absence of cultural resources within the Project area. The letter from
NAHC along with a list of Native American Tribes who may have knowledge of cultural resources in the
Project area is provided in Appendix C: Cultural Resources.
a) Cause a substantial adverse change in the significance of a historical resource pursuant to
§15064.5?
Less than Significant with Mitigation Incorporated: A non -confidential CHRIS records request was
conducted by EIC to determine the presence of culturally and historically significant resources within and
near the Project area. According to the report (Appendix C: Cultural Resources), there have been 92
studies on cultural resources and there are 56 cultural resource properties documented in the Highway 111
City of La Quinta Highway 111 Corridor Specific Plan 3-52
Environmental Analysis — Cultural Resources
Corridor. Two historically significant properties were identified in the CHRIS records search, both being
Point Happy Ranch, which is located at the intersection of Highway 111 and Washington Street. Although
this is within the Project limits, potential impacts to historic resources would be mitigated through the
implementation of Cultural Resource mitigation measures CRA through CR-9.
The designated Project site was not identified as Sacred Land based on the examination conducted by
NAHC. However, as acknowledged previously, the absence of specific information about cultural resources
in the SLF does not necessarily imply the absence of such resources in the Project area. Before
development activities commence, it is necessary for a cultural resource expert to conduct a survey to
ascertain the existence or non-existence of culturally significant resources. Additionally, it is important to
coordinate with local Native American Tribes in the vicinity. Employing cultural resource mitigation
measures (CR-1 through CR-9) would aid in minimizing potential impacts on significant cultural and
historical resources that might be found within or close to the Project boundaries.
Furthermore, the Highway 111 Corridor is not designated on the NRHP, and it is advisable to conduct a
cultural resource study before initiating any development activities within the Project area. In the event that
archaeological resources are encountered during ground -disturbing activities, the construction contractor
would implement mitigation measures CR-1 through CR-9. The use of appropriate mitigation efforts would
help reduce potential impacts on historic and cultural resources to a less then significant level.
Mitigation Measures: CR-1 through CR-9.
b) Cause a substantial adverse change in the significance of an archaeological resource
pursuant to §15064.5?
Less than Significant with Mitigation Incorporated: Results from the non -confidential CHRIS records
request demonstrate that there are no recorded archaeological resources within the Project area.
This Specific Plan is a regulatory and policy document with the intention to guide development along the
Highway 111 Corridor. No development is proposed as part of this Specific Plan and, therefore, the Project
would not impact any unknown archaeological resources. This Specific Plan enables future projects to use
this impact analysis for environmental assessments. Although this programmatic CEQA analysis offers a
general overview, it may not cover all specific project impacts. Future developments may require site -
specific archaeological surveys and reports to assess and mitigate impacts on significant archaeological
resources, as outlined in mitigation measures CRA through CR-9.
Mitigation Measures: CR-1 through CR-9.
c) Disturb any human remains, including those interred outside of formal cemeteries?
Less than Significant with Mitigation Incorporated: The Project area consists of previously developed
land; thus it is unlikely for human remains to be exposed during any future construction activities.
Nonetheless, future development and ground excavations would be closely monitored to ensure the
identification of any previously undiscovered remains. Given that the proposed Specific Plan serves as a
regulatory and policy document with no current development plans, there is no immediate impact on any
unidentified human remains within the Project area. However, if such remains are encountered during
future development, implementation of mitigation measures CR-1 through CR-9 would provide appropriate
instruction on the treatment of any human remains discovered during construction to reduce potential
impacts to cultural and historic resources.
Mitigation Measures: CR-1 through CR-9.

Cultural Resources Mitigation Measures
Implementation of mitigation measures CR-1 through CR-9 would reduce potential impacts to a less -than -
significant level during future construction activities. Appropriate pre -construction training and a data
recovery plan (if needed) would be implemented to address potential discovery of unanticipated
archaeological resources and to preserve and/or record those resources consistent with appropriate laws
and requirements. Proposed mitigation measures for future development are outlined below.

shall include a description of the types of cultural material that may be encountered, cultural
sensitivity issues, the regulatory environment, and the proper protocol for treatment of the materials
in the event of a find. The WEAP training document shall include materials that convey the
information noted above, which shall be maintained in an area accessible to all construction
personnel so that it may be reviewed regularly by construction staff.
• CR-2: Pre -Excavation Agreement
Prior to the issuance of Grading Permits, the Applicant/Owner shall enter into a pre -excavation
agreement, otherwise known as a Tribal Cultural Resources Treatment and Tribal Monitoring
Agreement with consulting Tribal Monitor associated within the area. A copy of the agreement shall
be included in building and development plans and permit applications with the City. The purpose of
this agreement shall be to formalize protocols and procedures between the Applicant/Owner and the
consulting Tribal Monitor associated with the area for the protection and treatment of, including but
not limited to, Native American human remains, funerary objects, cultural and religious landscapes,
ceremonial items, and traditional gathering areas and tribal cultural resources located and/or
discovered through a monitoring program in conjunction with the construction of the proposed
project, including additional archaeological surveys and/or studies, excavations, geotechnical
investigations, grading, and all other ground disturbing activities. At the discretion of the consulting
Tribal Monitor, artifacts may be made available for 3D scanning/printing, with scanned/printed
materials to be curated at a local repository meeting the federal standards of 36CFR79.
• CR-3: Retention of Qualified Archaeologist and Tribal Monitor
Prior to the issuance of a Grading Permits, the Applicant/Owner or Grading Contractor shall provide
executed contracts or agreements with a Qualified Archaeologist and consulting Tribal Monitor, at
the Applicant/Owner or Grading Contractor's expense, to implement the monitoring program, as
described in the pre -excavation agreement.
• CR-4: Tribal Cultural Monitor Coordination During Ground Disturbing Activities
The Qualified Archaeologist and consulting Tribal Monitor shall attend all applicable pre -construction
meetings with the General Contractor and/or associated subcontractors to present the
archaeological monitoring program. The Qualified Archaeologist and consulting Tribal Monitor shall
be present on -site full-time during grubbing, grading, and/or other ground altering activities,
including the placement of imported fill materials or fill used from other areas of the Project site, to
identify any evidence of potential archaeological or tribal cultural resources. All fill materials shall be
absent of any and all tribal cultural resources.
City of La Quinta Highway 111 Corridor Specific Plan 3-54
Environmental Analysis — Cultural Resources
• CR-5: Controlled Grade Procedure
To detect important archaeological artifacts and cultural resources during monitoring, a "Controlled
Grade Procedure" must be created by a Qualified Archaeologist. This will be done in consultation
with the consulting Tribal Monitor, relevant consulting Tribes, and the Applicant/Owner, and needs
approval from City representatives. The procedure will set guidelines for machinery work in sensitive
areas identified during cultural resource monitoring. It will cover aspects like operating speed,
removal increments, weight, and equipment features. A copy of this procedure must be included in
the Grading Plan submissions for Grading Permits.
• CR-6: Discovery of Tribal Cultural Resources
The Qualified Archaeologist and consulting Tribal Monitor can stop ground -disturbing activities if
undiscovered tribal cultural resources or artifacts are found. All work must cease in the vicinity of
any archaeological discovery until the Qualified Archaeologist and Tribal Monitor can assess the
context of the find, including its significance, potential eligibility for the California Register of
Historical Resources (CRHR), and whether the project would have a direct impact on the resource.
If buried cultural deposits are encountered, the Archaeologist and Tribal Monitor may request that
construction halt nearby and must notify a Qualified Archaeologist within 24 hours for investigation.
Work will be redirected away from these areas for assessment. Minor finds will be documented and
secured for later repatriation; if items cannot be securely stored on -site, they may be stored off -site.
Minor finds include archaeological materials that are isolated, lack context, and are unlikely to
indicate a larger or significant site. If the discovered resources are deemed potentially significant,
the involved Tribes will be notified for consultation on their respectful treatment. Avoidance of
significant resources is preferred, but if not feasible, a data recovery plan may be required. The
consulting Tribes will be consulted on this plan as well.
For resources under a data recovery plan, a proper sample will be collected using professional
methods, reflecting tribal values. The Tribal Monitor must be present during any resource collection
or cataloging. If the Qualified Archaeologist does not collect the resources, the Tribal Monitor may
do so. Ground -disturbing work will not resume until the resources are documented and/or protected.
• CR-7: Treatment of Tribal Cultural Resources
The landowner shall relinquish ownership of all cultural resources unearthed during all ground
disturbing activities, and from any previous archaeological studies or excavations on the Project site
to the affiliated consulting Tribe, as determined through the appropriate process, for respectful and
dignified treatment and disposition, including reburial at a protected location on -site, in accordance
with the Tribe's cultural and spiritual traditions. All cultural materials that are associated with burial
and/or funerary goods would be repatriated to the Most Likely Descendant as determined by the
NAHC per California Public Resources Code Section 5097.98. No tribal cultural resources shall be
subject to curation.
• CR-8: Tribal Cultural Monitoring Report
A monitoring report and/or evaluation report, if appropriate, which describes the results, analysis,
and conclusions of the archaeological monitoring program (e.g., data recovery plan) shall be
submitted by the Qualified Archaeologist, along with the consulting Tribal Monitor's notes and
comments, to the City of La Quinta Planning Division for approval.
City of La Quinta Highway 111 Corridor Specific Plan 3-55
Environmental Analysis — Cultural Resources
• CR-9: Unanticipated Discovery of Human Remains
As specified by California Health and Safety Code Section 7050.5, if human remains are found on
the Project site during construction or during archaeological work, the person responsible for the
excavation, or his or her authorized representative, shall immediately notify the Riverside County
Coroner's Office by telephone. No further excavation or disturbance of the site or any nearby area
reasonably suspected to overlie adjacent remains shall occur until the Coroner Medical Examiner
has made the necessary findings as to origin and disposition pursuant to Public Resources Code
5097.98. If such a discovery occurs, a temporary construction exclusion zone shall be established
surrounding the area of the discovery so that the area would be protected, and consultation and
treatment could occur as prescribed by law. If suspected Native American remains are discovered,
the remains shall be kept in -situ, or in a secure location in close proximity to where they were found,
and the analysis of the remains shall only occur on -site in the presence of a Tribal Monitor. By law,
the Coroner Medical Examiner shall determine within two working days of being notified if the
remains are subject to his or her authority. If the Coroner Medical Examiner identifies the remains to
be of Native American ancestry, he or she shall contact the NAHC within 24 hours. The NAHC shall
make a determination as to the Most Likely Descendent. If human remains are discovered, notify the
consulting Tribe's Tribal Historic Preservation Officer.

Environmental Analysis — Energy Resources
3.6 Energy Resources
Would the project:
a) Result in potentially significant environmental
impacts due to wasteful, inefficient, or unnecessary
consumption of energy resources, during project
construction or operation?
b) Conflict with or obstruct a state or local plan for
renewable energy or energy efficiency?
Electricity in the City is provided by the Imperial Irrigation District (IID), which provides power to eastern CV
and Imperial County. IID derives over 60% of its power from various facilities, notably the Coachella Gas
Turbine facility in Coachella. Its transmission network encompasses the innovative Green Path system,
transmitting geothermal energy harnessed in Imperial County. Diversifying its portfolio, IID is committed to
achieving a minimum of 45% of its electricity from alternative sources like geothermal, solar, and wind
energy by 2027 (City of La Quinta, 2022; IID, 2024).
a) Result in potentially significant environmental impacts due to wasteful, inefficient, or
unnecessary consumption of energy resources, during project construction or operation?
Less Than Significant: Future enhancements along the Highway 111 Corridor would prioritize efficient
energy use and resource consumption. The proposed improvements under the Specific Plan would
necessitate collaboration with IID to assess their capacity to support and sustain future developments in the
corridor. Potential future developments along Highway 111 have the potential to increase the electrical
demands on IID's systems. Developers planning future projects would need to apply for electrical service
with IID, which would conduct evaluations of project design engineering and estimate costs associated with
potential increases in energy demand. Information required by IID includes detailed loading and panel size
specifications to assist in determining the requirements for supplying permanent power to improvements
within the Specific Plan area. Additionally, all development activities within the Specific Plan area must
undergo review and approval by the City, adhering to applicable local, state, and federal laws as well as
aligning with the City's General Plan and this Specific Plan. Given that this Specific Plan serves as a high-
level guide for the redevelopment of the Highway 111 Corridor, no site -specific electrical development plans
or proposals are included or granted within it. Consequently, impacts on critical energy resources are
expected to be less than significant.
Mitigation Measures: No mitigation measures required.
b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency?
No Impact: Senate Bill 100 (SB 100), passed in September 2018, aims to speed up the State's Renewable
Portfolio Standards Program. This involves directing electricity providers to increase their sourcing from
eligible renewable energy sources to 100 percent of their total retail sales by 2045. The proposed project
intends to use the current IID electricity grid. All construction facilitated by the proposed Project must
adhere to Title 24 standards and current building codes. Importantly, the Project aligns with the state plan
for renewable energy and does not pose any new impacts beyond what was anticipated and evaluated
City of La Quinta Highway 111 Corridor Specific Plan 3-57
Environmental Analysis — Energy Resources
under the Specific Plan. The Energy Element and Mineral Resource Element of the General Plan highlight
two policies along with their corresponding programs related to sustainable energy use, as detailed below
(City of La Quinta, 2022):
Policy EM 1.1: Strongly encourages conservation of energy resources.
— Program EM 1.1 a: Review and amend, as appropriate, Zoning Ordinance procedures and
standards to include site orientation, solar control and use of passive heating and cooling
techniques.
Policy EM 1.2: Supports the use of alternative energy and the conversion of traditional energy
sources to alternative energy.
— Program EM1.2a: Encourage installation of alternative energy devices on new and existing
development. Programs may include City -funded incentive programs; matching fund programs
with IID, The Gas Company and alternative energy providers, as well as other programs as
they become available.
— Program EM1.2b: As funding and applicability allows, incorporate Compressed Natural Gas
(CNG), hybrid or electric vehicles into the City fleet as vehicles are replaced, with a target to
complete the conversion by 2035.
— Program EM1.2c: Continue participation in the Sunline Transit Agency, and promote the use of
alternative fuel technologies for its buses.
— Program EM1.2d: As appropriate, incorporate LED or other energy -efficient lighting in signals
and lights throughout the City.
— Program EM1.2e: Explore opportunities to provide a CNG and other alternate fueling station in
the City.
— Program EM1.2f.- Implement, as appropriate, energy efficient improvements in City buildings
and facilities using Energy Efficiency Conservation Block Grant or similar funds.
The proposed Specific Plan would align with the energy policies outlined in the City's General Plan by
promoting sustainable and energy -efficient development along the Highway 111 Corridor. This approach
would facilitate better planning and adaptability for the corridor as development advances and the
population expands. As such, no impacts are anticipated.
Mitigation Measures: No mitigation measures required.

Environmental Analysis - Geology and Soils
3.7 Geology and Soils
Would the project:
a) Directly or indirectly cause potential substantial
adverse effects, including the risk of loss, injury, or
death involving:
i. Rupture of a known earthquake fault, as
delineated on the most recent Alquist-Priolo
Earthquake Fault Zoning Map issued by the
State Geologist for the area or based on other
substantial evidence of a known fault? Refer to
Division of Mines and Geology Special
Publication 42?
ii. Strong seismic ground shaking?
iii. Seismic related ground failure, including
liquefaction?
iv. Landslides?
b) Result in substantial soil erosion or the loss of
topsoil?
c) Be located on a geologic unit or soil that is
unstable, or that would become unstable as a
result of the project, and potentially result in on, or
off, site landslide, lateral spreading, subsidence,
liquefaction or collapse?
d) Be located on expansive soil, as defined in Table
18-1-B of the Uniform Building Code (1994),
creating substantial direct or indirect risks to life or
property?
e) Have soils incapable of adequately supporting the
use of septic tanks or alternative wastewater ✓
disposal systems where sewers are not available
for the disposal of wastewater?
f) Directly or indirectly destroy a unique
paleontological resource or site or unique geologic ✓
feature?
Geologic Setting
The natural landscape of the City exhibits significant variation, with elevations ranging from 130 feet below
sea level to over 1,700 feet above sea level in the foothills of the Santa Rosa Mountains. Predominantly
situated in a valley, the City experiences hot, arid summers and relatively mild winters. This climate
influences the composition of soils. La Quinta contains predominantly sandy, well -drained soils, with rocky
terrain prevalent in the Santa Rosa foothills. Soil composition in the Project area is mainly characterized by
fine sandy loam with alluvial sand and gravel of the Whitewater River at the northeastern portions of the
project area and a mix of alluvial sand and clay and wind -laid dune sand throughout the rest of the Project
area (City of La Quinta, 2022; USDA, 2024).
City of La Quinta Highway 111 Corridor Specific Plan 3-59
Environmental Analysis — Geology and Soils
The Project site is not within any of the State of California designated Alquist-Priolo Earthquake Fault
Rupture Zones (California DOC, 2024a). Nevertheless, the region is susceptible to seismic activity due to
the presence of active faults nearby. Notably, the historically active San Andreas Fault lies approximately 5
miles northwest of the City, while the San Jacinto Fault is situated about 17 miles southwest (City of La
Quinta, 2002). In 1972, California implemented the Alquist-Priolo Earthquake Fault Zoning Act to reduce the
risk of fault rupture. This law prohibits building structures intended for human use over the trace of an active
fault.
The Project area is subject to strong seismic activities and is situated within Zone 4, the most intense
seismic shaking zone (Title 24 of the California Code of Regulations). Strong ground shaking has the
potential to cause hazards including landslides, liquefaction, and structural damage, although liquefaction is
not considered a hazard to development at the Project site, mainly due to the significant depth of
groundwater. Zone 4 jurisdictions are responsible for diligently identifying any structures that could
potentially pose hazards or fall below standard safety requirements. Subsequently, they are obligated to
develop and execute thorough mitigation programs aimed at reducing the risks associated with such
structures, and ensuring the safety and well-being of residents and infrastructure within their jurisdiction
(City of La Quinta, 2002; 2022).
The following policies outlined in the City's General Plan would ensure that the impacts of seismic hazards
are carefully considered and mitigated alongside future development efforts:
Policy GEO-1.1: The City shall maintain and periodically update an information database and
maps that identify local and regional geologic and seismic conditions.
— Program GEO-1.1a: The City shall periodically confer with the California Division of Mines and
Geology, Riverside County, neighboring communities, and other appropriate agencies to
improve and routinely update the database.
Policy GEO-1.2: The City shall continue to require that development in areas subject to rockfall,
landslide, liquefaction and/or other geotechnical hazards described in this Element, prepare
detailed geotechnical analyses that include mitigation measures intended to reduce potential
hazards to less than significant levels.
Policy GEO-1.3: The City shall require that development in areas subject to collapsible or
expansive soils conduct soil sampling and laboratory testing and implement mitigation measures
that minimize such hazards.
— Program GEO-1.3a: The Building and Safety Department shall review and determine the
adequacy of soils and/or other geotechnical studies conducted for proposed projects and
enforce the implementation of mitigation measures.
Policy GEO-1.4: The City shall require that all new structures be built in accordance with the latest
adopted version of the Building Code.
Policy GEO-1.5: The City shall continue to require that structures that pose a safety threat due to
inadequate seismic design are retrofitted or removed from use, according to law.
Policy GEO-1.6: The City shall coordinate and cooperate with public and quasi -public agencies to
ensure that major utilities continue to be functional in the event of a major earthquake.
— Program GEO-1.6.a: The City shall maintain working relationships and strategies between the
Public Works Department, utility providers, and other appropriate agencies to strengthen or
relocate utility facilities and take other appropriate measures to safeguard major utility
distribution systems.
City of La Quinta Highway 111 Corridor Specific Plan 3-60
Environmental Analysis — Geology and Soils
a.i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo
Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other
substantial evidence of a known fault? Refer to Division of Mines and Geology Special
Publication 42.
No Impact: There are no Alquist-Priolo zoned faults in the City (City of La Quinta, 2022). The prospect of
future development in the proposed Project area carries a seismic risk given its proximity to the San
Andreas Fault, a well-known and active fault line, as outlined in the most recent Alquist-Priolo Earthquake
Fault Zoning Map (State of California, 2022). The San Andreas Fault, positioned approximately 5 miles
north of the City, represents a significant geological feature considered the "master fault" in southern
California. Additionally, the region is influenced by the San Jacinto Fault Zone approximately 17 miles to the
southwest of the Project area, the Burnt Mountain Fault roughly 15 miles north of the City, and the Indio
Hills Fault situated approximately 2 miles east of the San Andreas Fault. These faults collectively shape the
seismic characteristics of the area. As seismic events can lead to ground shaking, displacement, and other
hazards, thorough consideration of these geological factors is crucial for informed decision -making in land -
use planning and construction practices. Adherence to the City's General Plan and seismic building codes
are imperative to enhance the resilience and safety of any future infrastructure projects. As such, rupture of
known earthquake faults in the area are not expected to generate substantial adverse effects to future
development along the Highway 111 Corridor. No impacts are anticipated.
Mitigation Measures: No mitigation measures required.
a.ii) Directly or indirectly cause potential substantial adverse effects, including the risk of loss,
injury, or death involving strong seismic ground shaking?
Less Than Significant Impact: The Project is situated within a seismically active area close to several
seismic sources capable of generating moderate to strong ground shaking. Given the proximity of the San
Andreas Fault and other significant active faults (San Jacinto Fault Zone, Burnt Mountain Fault, and Indio
Hills fault), as well as other active faults within California, the Project area could experience strong ground
shaking during future development along the Highway 111 Corridor. Shaking intensity could range from
moderate to strong and would be expected to result in moderate to extensive damage, especially to
buildings that are older or poorly constructed. The Project area is anticipated to encounter moderate to
intense earthquakes throughout its design lifespan. Nevertheless, the Project would be engineered to meet
the highest mandated standards, ensuring resilience against potential seismic activity as per the most
recent specifications from the State of California Building Code and Department of Transportation.
Furthermore, the Local Hazard Mitigation Plan (LHMP) outlines the specific risks linked to earthquakes and
outlines measures for mitigation, preparedness, response, and recovery in case of seismic activity within
the City. By addressing both natural and man-made hazards, the LHMP aims to reduce La Quinta's
susceptibility and underscores the City's dedication to safeguarding residents, property, and critical
infrastructure (City of La Quinta, 2023). Moreover, the City's Emergency Operations Plan (EOP) details the
coordinated responses to various emergencies, encompassing natural disasters, technological incidents,
and national security threats that could impact the City. The EOP establishes protocols aligned with the
California Standardized Emergency Management System and designates evacuation routes for different
scenarios (City of La Quinta, 2010). Following and executing these plans would safeguard and direct
development along the Highway 111 Corridor, averting negative consequences for the community and City
infrastructure in future development initiatives. Project -related impacts associated with seismic ground
shaking would be less than significant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-61
Environmental Analysis — Geology and Soils
a.iii) Directly or indirectly cause potential substantial adverse effects, including the risk of loss,
injury, or death involving seismic related ground failure, including liquefaction?
Less Than Significant Impact: Liquefaction occurs when ground shaking of relatively long duration and
intensity over 0.2 g occurs in areas of loose, unconsolidated soils with relatively shallow groundwater
depths (50 feet or less). The sudden increase in water pressure in pores between soil grains may
substantially decrease soil shear strength. This creates a condition where soil takes on the qualities of a
liquid or a semi -viscous substance. Liquefaction can result in ground settlement, ground undulation, lateral
spreading or displacement, and flow failures. Structures may sink or tilt as bearing capacity decreases,
causing substantial damage (City of La Quinta, 2022). The City's General Seismic Hazard Map shows that
the Project area is not considered to be in a moderate or high Liquefaction Susceptibility area. Therefore,
impacts would be less than significant.
Mitigation Measures: No mitigation measures required.
a.iv) Directly or indirectly cause potential substantial adverse effects, including the risk of loss,
injury, or death involving landslides?
Less Than Significant Impact: Landslides and rockfall can occur when unstable slope conditions are
worsened by strong ground motion caused by seismic events. Conditions that lead to landslide vulnerability
include high seismic potential; rapid uplift and erosion that creates steep slopes and deeply incised
canyons; folded and highly fractured rock; and rock with silt or clay layers that are inherently weak. Rockfall
and rockslides are also common on very steep slopes. Landslides have been recorded after periods of
heavy rainfall, and rockfall has been associated with slope failure during drier periods (City of La Quinta,
2022). The City's General Seismic Hazard Map shows that the Project Area is not an Earthquake Induced
Instability Area of Concern. Although the Project area is primarily flat, northwest of the Project area is
susceptible to rock falls. Nonetheless, by adhering to the City's General Plan and standards of the LHMP,
impacts involving the risk of landslides are anticipated to be less than significant.
Mitigation Measures: No mitigation measures required.
b) Result in substantial soil erosion or the loss of topsoil?
Less Than Significant Impact: The Specific Plan does not encompass existing development proposals,
nor does it provide entitlements for development. While the Specific Plan itself would not cause soil erosion,
activities such as land clearing, grading or excavations, and future development could potentially lead to
soil erosion. Future construction activities, including cut, fill, removal of vegetation, and operation of heavy
machinery would disturb soil and, therefore, have the potential to cause erosion.
State law mandates that new development projects must comply with the statewide General Construction
Permit (CGP) under the National Pollutant Discharge Elimination System (NPDES). This program oversees
discharges from construction activities and monitors stormwater quality in municipal systems. Projects must
submit a Stormwater Pollution Prevention Plan (SWPPP) as part of their permit application.
Additionally, according to the City's General Plan, the Project area has a very high wind erodibility rating
caused by strong winds in the CV. As such, any future development activities within the Highway 111
Corridor should be performed in compliance with the BMPs prescribed in the City's Municipal Code and
General Plan, including Policies GEO-1.1 through GEO-1.6a, as referenced above (City of La Quinta, 2021;
2022). Therefore, impacts are expected to be less than significant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-62
Environmental Analysis — Geology and Soils
c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a
result of the project, and potentially result in on, or off, site landslide, lateral spreading,
subsidence, liquefaction or collapse?
Less Than Significant Impact: According to the City's General Plan, the proposed Project Area consists
of three different geological units. Directly to the north of Highway 111 in the Project area, the soil consists
of alluvial sand and clay and just north that is alluvial sand and gravel of Whitewater River. The southern
section of the Project area south of Highway 111 consists of a combination of alluvial sand and gravel as
well as wind -laid dune sand (City of La Quinta, 2022). Future development along the Highway 111 Corridor
should be consistent with the City's General Plan and must adhere to established state and local
regulations to mitigate risks related to unstable and expansive soils. As such, impacts are expected to be
less than significant.
Mitigation Measures: No mitigation measures required.
d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994),
creating substantial direct or indirect risks to life or property?
Less Than Significant Impact: Expansive soils are soils containing fine-grained materials such as silts
and clays in varying amounts. With changes in moisture content, clay minerals can shrink or swell, creating
pressure that may affect structures or other surface improvements. Prior to any future ground -disturbing
activities within the Highway 111 Corridor, it is recommended that soil properties and type be identified to
ensure compliance with the Uniform Building Code. Furthermore, by adhering to the City's General Plan
Policy GEO-1.3, potential impacts to property development due to expansive soils would be less than
significant.
Mitigation Measures: No mitigation measures required.
e) Have soils incapable of adequately supporting the use of septic tanks or alternative
wastewater disposal systems where sewers are not available for the disposal of wastewater?
Less Than Significant: Development under the proposed Specific Plan would continue to be connected to
the CVWD's wastewater treatment system. Future wastewater treatment proposed for development must
comply with Regional Water Control Board regulations to prevent any potential discharge into local water
sources. The installation, use, sizing, and location of wastewater treatment systems to support future
development would undergo review and approval by both the Riverside County Environmental Health
Department and the Regional Water Quality Control Board (RWQCB). Additionally, it is likely that
geotechnical engineering analysis may be required to secure future building permits to ensure the safe and
proper installation of wastewater treatment systems.
Subsequent development may necessitate additional CEQA assessment of project -specific impacts before
proceeding, alongside adherence to local laws and regulations. The potential wastewater impacts stemming
from the adoption of the Specific Plan are expected to be less than significant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-63
Environmental Analysis — Geology and Soils
f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic
feature?
Less Than Significant With Mitigation Incorporated: Paleontological resources encompass not only
fossil remains but also fossil sites and geological formations that have yielded fossil material. The proposed
Specific Plan does not entail specific development projects or confer entitlements for development.
Moreover, the proposed land use blueprint would align with the current land use designations outlined in the
City's General Plan. As the Specific Plan functions as a policy and regulatory framework, it would not
directly cause the disturbance of paleontological resources. However, potential future enhancements to
execute the Specific Plan could potentially impact these resources. Though there are no known unique
paleontological resources, site, or unique geologic feature present within the Project area, that does not
mean undiscovered paleontological resources do not exist. To address this, mitigation measure GEO-1 has
been proposed to mitigate potential impacts on undiscovered paleontological resources. As such, impacts
are expected to be less than significant.
Mitigation Measures: GEO-1.
Geology and Soils Mitigation Measures
• GEO-1: Protect Paleontological Resources during Construction Activities
Prior to ground disturbing activities, all field personnel will receive training on paleontological
resources, including potential fossils that may be discovered and response steps, while a qualified
paleontologist will prepare a Paleontological Resources Monitoring and Mitigation Plan (PRMMP).
If fossils (like bones, teeth, or well-preserved plants) are found during construction, the City will stop
work within 50 feet and notify a paleontologist to document and assess the find. The paleontologist
may allow work to continue or recommend salvaging the fossils if necessary and will suggest
appropriate treatment methods. Collected fossils will be sent to an accredited institution for curation
and preservation.
All earth -moving operations deeper than two feet must have a qualified paleontological monitor.
Continuous monitoring is needed if fossil -rich lakebed sediments are found. The monitor can stop
work to identify and salvage fossils and may halt equipment for large specimens. A monitoring plan
must be submitted to the City before any permits are issued or soil is disturbed. Grading and
excavation must comply with La Quinta Code and regulations.
After ground disturbing activities and any necessary fossil curation, the project paleontologist will
prepare a final report detailing the results of the PRMMP.

3.8 Greenhouse Gas Emissions
Would the project:
a) Generate greenhouse gas emissions, either
directly or indirectly, that may have a significant ✓
impact on the environment?
b) Conflict with an applicable plan, policy or
regulation adopted for the purpose of reducing the ✓
emissions of greenhouse gases?
As described in Section 1, Project Information, the Project is consistent with the City's current 2035 General
Plan. Therefore, growth parameters such as population and vehicle activity are consistent with the General
Plan and have been previously analyzed in the certified General Plan EIR. The following General Plan
policies and programs are applicable to and would be implemented by project:
Policy AQ-1.7: Greenhouse gas emissions associated with a development project shall
demonstrate adherence to the City's GHG Reduction Plan.
The City adopted the Greenhouse Gas Reduction Plan (GHG Plan) in 2013. The City's GHG Plan includes
emission reduction targets for year 2020 and year 2035 that are consistent with the State's Assembly Bill 32
(AB 32) reduction targets. Specifically, the City's reduction targets are:
10 percent below 2005 levels by 2020, and
28 percent below 2005 levels by 2035
a,b) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant
impact on the environment, conflict with an applicable plan, policy, or regulation adopted for
the purpose of reducing the emissions of greenhouse gases?
Less Than Significant Impact: The applicable greenhouse gas reduction plan is the City's GHG Plan,
which demonstrates a community -wide emissions reduction strategy consistent with the AB 32 reduction
goals. Therefore, if a project is consistent with the City's GHG Plan, the project would not generate
greenhouse gas emissions that may have a significant impact on the environment. The Specific Plan's
consistency with the City's GHG Plan is assessed in Table 3.3, below. As demonstrated in the table, the
Specific Plan is consistent with the City's GHG Plan. Therefore, the Project would not conflict with an
applicable GHG plan; the Specific Plan's greenhouse gas emissions generation impact would be less than
significant.

Environmental Analysis — Hazards and Hazardous Materials
3.9 Hazards and Hazardous Materials
Would the project:
a) Create a significant hazard to the public or the
environment through the routine transport, use, or
disposal of hazardous materials?
b) Create a significant hazard to the public or the
environment through reasonably foreseeable upset
and accident conditions involving the release of
hazardous materials into the environment?
c) Emit hazardous emissions or handle hazardous or
acutely hazardous materials, substances, or waste
within one -quarter mile of an existing or proposed
school?
d) Be located on a site which is included on a list of
hazardous materials sites compiled pursuant to
Government Code Section 65962.5 and, as a
result, would it create a significant hazard to the
public or the environment?
e) For a project located within an airport land use
plan or, where such a plan has not been adopted,
within two miles of a public airport or public use
airport, would the project result in a safety hazard
or excessive noise for people residing or working
in the project area?
f) Impair implementation of or physically interfere
with an adopted emergency response plan or
emergency evacuation plan?
g) Expose people or structures, either directly or
indirectly, to a significant risk of loss, injury or
death involving wildland fires?
* A material is considered hazardous by the state of California Health and Safety Code as any material that, because of quantity,
concentration, or physical or chemical characteristics, poses a significant present or potential hazard to human health and safety or
to the environment (CA HSC, 2022.). California categorizes hazardous materials into four categories. These include if the material
or waste is poisonous (toxicity), can be ignited by open flame (ignitability), can corrode other materials (corrosivity), or can react
violently, explode, or generate vapors when mixed with water (reactivity) (CCR, 2023b).
Future development along the Highway 111 Corridor would facilitate expansion of commercial activities that
may manufacture, transport, store, use, or dispose of hazardous materials and waste. Prior to any related
ground disturbing activities, developers may need to conduct site -specific research and technical studies to
assess the presence of hazardous materials and potential hazards within the Specific Plan area. This
information would ensure that future developers are well-informed about the necessary protocols for safely
handling, storing, and disposing of hazardous substances, as well as understanding any environmental
risks that could impact development projects in the area.
The following policies within the City's General Plan aim to address and mitigate health hazards associated
with hazardous materials in future development:
City of La Quinta Highway 111 Corridor Specific Plan 3-68
Environmental Analysis — Hazards and Hazardous Materials
Policy HAZ-1.1: The storage, transport, use and disposal of hazardous materials shall comply with
all City, County, State, and federal standards.
— Program HAZ-1.1. a: Continue to coordinate with all appropriate agencies to assure that local,
State and federal regulations are enforced.
— Program HAZ-1.1.b: Development plans for projects which may store, use or transport
hazardous materials shall continue to be routed to the Fire Department and the Department of
Environmental Health for review.
— Program HAZ-1.1.c: The City's Emergency Services Division shall maintain a comprehensive
inventory of all hazardous waste sites within the City, including underground fuel storage tanks.
Policy HAZ-1.2: To the extent empowered, the City shall regulate the generation, delivery, use and
storage of hazardous materials.
— Program HAZ-1.2.a: All facilities which produce, utilize, store or transport hazardous materials
shall be constructed in strict conformance with all applicable Building and Fire Codes.
Policy HAZ-1.3: Support Household Hazardous Waste
— Program HAZ-1.3.a: Continue to work with the County to assure regular household hazardous
waste disposal events are held in and around the City.
— Program HAZ-1.3.b: Educate the City's residents on the proper disposal of household
hazardous waste through the City's newsletter and by providing educational materials at City
Hall.
The analysis described in this section includes data on hazardous sites sourced from the San Diego
RWQCB GeoTracker Database and the California Department of Toxic Substances Control EnviroStor
Database, accessed as of June 2024.
a) Create a significant hazard to the public or the environment through the routine transport,
use, or disposal of hazardous materials?
Less Than Significant Impact with Mitigation Incorporated: Construction activities associated with the
Specific Plan may involve the handling of incidental amounts of hazardous materials such as fuels,
hydraulic liquids, oils, and solvents. Handling, storage, and transportation of hazardous materials would be
conducted in accordance with applicable federal and state laws and any hazardous waste materials would
be disposed of offsite. Given the proposed densification of the corridor and new commercial activities, there
would be greater potential for the transport of hazardous materials in Specific Plan area streets, increasing
the likelihood of potential spills or leaks from mobile sources. Changes in land use, such as modification,
increased activity, and reorganization, can potentially expose the public to environmental hazards
associated with the transportation, disposal, or use of hazardous materials. Furthermore, future
development or construction activities may also present risks to public health and the environment by
disturbing contaminated groundwater, soils, or hazardous building materials already present.
Future development within the Highway 111 Corridor would be required to adhere to the Specific Plan's
policies, the City's General Plan, and applicable federal and state laws and local regulations. As such,
environmental impacts associated with the handling and disposal of hazardous material would be mitigated
through the implementation of HAZ-1 and impacts are anticipated to be less than significant.
Mitigation Measures: HAZ-1.
City of La Quinta Highway 111 Corridor Specific Plan 3-69
Environmental Analysis — Hazards and Hazardous Materials
b) Create a significant hazard to the public or the environment through reasonably foreseeable
upset and accident conditions involving the release of hazardous materials into the
environment?
Less Than Significant Impact with Mitigation Incorporated: The Specific Plan would adhere to the
County's Hazardous Waste Management Plan (HWMP), which addresses the proper disposal, processing,
handling, storage, and treatment of hazardous materials. The City also has adopted this HWMP and
implements it at a local level.
In future redevelopment projects involving demolition of structures built more than 30 years ago, there is a
possibility of encountering asbestos materials. Therefore, an Asbestos Survey shall be conducted prior to
the commencement of any demolition activities, in compliance with Title 8 of the California Code of
Regulations. Title 8 of the California Code of Regulations, overseen by the California Division of
Occupational Safety and Health (Cal/OSHA), encompasses safety standards in the workplace, including
regulations related to hazardous materials such as asbestos. Title 8 addresses the handling, removal, and
disposal of asbestos during demolition activities. (CCR, 2023a).
Furthermore, future development within the Highway 111 Corridor shall comply with the City's General Plan
policies HAZ-1.1 through HAZ-1.3 to ensure impacts related to health hazards from hazardous materials
are taken into consideration and reduced or minimized in conjunction with future development.
All future development under the proposed Specific Plan would be required to comply with applicable
federal and state laws and local regulations pertaining to the transport, use, disposal, and accidental
release of hazardous materials, including but not limited to the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA), the Resource Conservation and Recovery Act (RCRA),
California Hazardous Waste Control Law, California Health and Safety Code, California Fire Code,
California Department of Public Health, South Coast AQMD, RCRA regulations, the City's Municipal Code
along with the General Plan policies listed above. Compliance with these laws, regulations, and policies
aims to mitigate potential environmental impacts associated with hazardous materials and hazards.
Through the inclusion of mitigation measure HAZA, future improvements within the Highway 111 Corridor
would be minimized to levels deemed insignificant.
Mitigation Measures: HAZ-1
c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances,
or waste within one -quarter mile of an existing or proposed school?
Less than Significant Impact with Mitigation Incorporated: La Quinta High School is about 0.18 miles
north of the Specific Plan area, while James Madison Elementary School is roughly 1.6 miles northeast.
Additionally, Amelia Earhart Elementary School and John Glenn Middle School are situated adjacent to
each other, approximately 1.5 miles north of the proposed Project development area. The Specific Plan is a
guidance -level document and does not include site -specific development plans, however, future
developments within the Specific Plan area may involve the release or handling of hazardous materials,
substances, or waste within a quarter -mile radius of any existing or proposed school. Therefore, future
development in the Highway 111 Corridor should adopt mitigation measure HAZA to reduce potential
impacts from hazardous materials, substances, or waste on nearby schools.
Mitigation Measures: HAZ-1.
City of La Quinta Highway 111 Corridor Specific Plan 3-70
Environmental Analysis — Hazards and Hazardous Materials
d) Be located on a site which is included on a list of hazardous materials sites compiled
pursuant to Government Code Section 65962.5 and, as a result, would it create a significant
hazard to the public or the environment?
Less Than Significant Impact with Mitigation Incorporated: The provisions in Government Code
Section 65962.5 are commonly referred to as the "Cortese List." A search of the Cortese List was
completed for the Project to determine if any known hazardous waste sites have been recorded on or
adjacent to the Specific Plan area. These include:
• Department of Toxic Substances Control EnviroStor database;
• List of Leaking Underground Storage Tank Sites from the Water Board GeoTracker database;
• List of solid waste disposal sites identified by the Water Board with waste constituents above
hazardous waste levels;
• List of "active" Cease and Desist Orders and Cleanup and Abatement Orders from the Water
Board; and
• List of hazardous waste facilities subject to corrective action pursuant to Section 25187.5 of the
Health and Safety Code.
Database searches conducted within a one -mile radius of the Specific Plan area returned two LUST
(Leaking Underground Storage Tank) Cleanup Sites within the Specific Plan area (Regional Water Board
Cases # 7T2253006; and 7T2253014 [DTSC, 2024; SWRCB, 2024]). LUST site 7T2253006 is located at
78611 Highway 111, La Quinta, CA 92253 and LUST site 7T2253014 is located at 46150 Washington
Street, La Quinta, CA 92253. The LUST sites, 7T2253006 and 7T2253014, are located where future
development may occur within the Highway 111 Corridor; however, the cases were closed in 2001 and
2003, respectively. The known contaminant for both LUST sites was gasoline, which was found in soil at
both LUST sites. Excavation cleanup activities were conducted shortly after the leaks were detected and
the cases were closed with no further regulatory action required. As such, it is likely that the closed sites
have little to no potential to present a lasting impact or adverse consequences that would impede the
feasibility of the proposed Specific Plan development.
As there are no other known hazardous sites or ongoing clean-up activities within the Project area that
would pose a hazardous risk, the implementation of the Specific Plan would not create significant hazards
to the public or environment. To prevent potential hazards to the public or environment from future
development under the Specific Plan, any construction or site disturbance in areas with recorded Cortese
List sites would require additional environmental assessment, such as Phase I or Phase II Environmental
Site Assessments, before excavation or major construction begins, as outlined in Mitigation Measure
HAZ-2.
Mitigation Measures: HAZ-2.
e) For a project located within an airport land use plan or, where such a plan has not been
adopted, within two miles of a public airport or public use airport, would the project result in
a safety hazard or excessive noise for people residing or working in the project area?
No Impact: The development area outlined in the Specific Plan is situated outside of an airport land use
plan and beyond a two-mile radius from any public use airport. The closest airport, Bermuda Dunes Airport,
is approximately four miles north of the Specific Plan area and is a public airport that is privately owned.
Additionally, the Jacqueline Cochran Regional Airport is a public county -owned airport located
approximately eight miles southeast of the Specific Plan area. Despite this proximity, it is expected that the
proposed development would not negatively affect airport operations or safety. Since the Highway 111
City of La Quinta Highway 111 Corridor Specific Plan 3-71
Environmental Analysis — Hazards and Hazardous Materials
Corridor is located outside any Airport Influence Area, it is not subject to an Airport Land Use Compatibility
Plan requirements (Riverside County Airport Land Use Commission, 2004). Therefore, no impacts related
to airport land use plans or safety hazards are expected to occur.
Mitigation Measures: No mitigation measures required.
f) Impair implementation of or physically interfere with an adopted emergency response plan or
emergency evacuation plan?
Less Than Significant: Highway 111 serves as an arterial route through the City and can be utilized as an
evacuation path. Implementation of the proposed Specific Plan would not hinder access along Highway 111
and to nearby neighborhoods. The City's Emergency Management Division has established an EOP
detailing mitigation, preparedness, response, and recovery efforts in emergencies (City of La Quinta, 2010).
Additionally, the City operates a Community Emergency Response Team (CERT) Program, educating
residents on disaster preparedness and basic response skills such as fire safety and rescue operations.
The City's LHMP further reduces risks from natural and man-made hazards, emphasizing protection for
residents, property, and critical infrastructure (City of La Quinta, 2023).
The proposed Highway 111 Corridor Specific Plan includes transportation and street enhancements aimed
at improving multi -modal connectivity and pedestrian -friendliness without disrupting traffic flow or
emergency access. All future development would undergo review and approval by the City of La Quinta Fire
Department to ensure compliance with fire safety standards and non-interference with emergency access.
Adherence to the General Plan policies ensures that local emergency plans are regularly updated with the
latest disaster preparedness information and evacuation procedures. By aligning with the goals of the EOP,
CERT Program, LHMP, and General Plan, development along Highway 111 would proceed responsibly,
minimizing impacts on emergency response and evacuation protocols and promoting community safety.
Therefore, the Project is expected to have a less than significant impact on established emergency plans
and evacuation procedures.
Mitigation Measures: No mitigation measures required
g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or
death involving wildland fires?
No Impact: The Project area is situated outside of wildland fire hazard zones and is not prone to wildfires
(CAL FIRE, 2023). Development along the Highway 111 Corridor would adhere to the City's LHMP and
comply with Building and Fire codes established to ensure adequate fire safety standards. These standards
consider factors such as building type, design, intended occupancy, and usage. Additionally, the City has
partnered with the Riverside County Fire Department to enhance fire safety measures under a
comprehensive fire services agreement. By following the guidelines set forth in the City of La Quinta's
LHMP, the Project is expected to have no impact on fire safety, ensuring compliance and safety standards
are met.
Mitigation Measures: No mitigation measures required.
Hazards and Hazardous Materials Mitigation Measures
• HAZ-1: Hazardous Materials Handling and Planning
New development projects in the Specific Plan area must comply with local, state, and federal
regulations by submitting development plans and permits to the City for review. Projects intending to
City of La Quinta Highway 111 Corridor Specific Plan 3-72
Environmental Analysis — Hazards and Hazardous Materials
use or store hazardous materials must prepare a Spill Prevention Countermeasure Contingency
(SPCC) Plan outlining spill containment protocols, along with maintaining an onsite SPCC spill kit.
Additionally, developments proposing storage and use of hazardous materials above reporting
thresholds must create a Hazardous Materials Business Emergency Plan (HMBEP) as per Chapter
6.95 of the California Health & Safety Code and Title 19, Division 2 of the California Code of
Regulations. The HMBEP requires approval from the County of Riverside Certified Unified Program
Agency (CUPA) and the Department of Environmental Health prior to business operation
commencement.
• HAZ-2: Phase I and/or Phase II Site Assessment
Projects within the Specific Plan area that involve excavation at locations with recorded Cortese List
sites must undergo a Phase I Environmental Site Assessment, and where necessary, Phase II
sampling. If the Phase I assessment identifies the need for remediation, the project sponsor must
adhere to all remediation and abatement directives specified by the DTSC, RWQCB, or relevant
regulatory agencies.

Hydrology of the Region
The City is situated in the CV and exhibits a distinct hydrological profile shaped by its desert environment
and unique geological characteristics. The City experiences a hot desert climate, characterized by low
annual precipitation and high temperatures, which significantly influence its hydrology.
La Quinta receives minimal precipitation, averaging 3-5 inches annually, mostly during winter months (City
of La Quinta, 2022). High evaporation rates from intense solar radiation limit surface water resources and,
as such, the City heavily depends on groundwater from CV aquifers. The City's hydrology is shaped by the
San Andreas Fault system and nearby mountain ranges, influencing groundwater recharge and aquifer
sustainability. Given its arid climate and groundwater reliance, the City prioritizes sustainable water
management through conservation, monitoring groundwater levels, and exploring alternative water sources
to address potential challenges from droughts and growing water demands (City of La Quinta, 2022).
Sustainable water management practices are essential to support the City's growth and development while
safeguarding its water resources.
City of La Quinta Highway 111 Corridor Specific Plan 3-74
Environmental Analysis — Hydrology and Water Quality
Water Management and Flood Controls
The Riverside County Flood Control and Water Conservation District (RCFC) oversees the design of flood
control structures across the region. These structures manage runoff from areas beyond the City, such as
the surrounding mountains. The CVWD holds extensive responsibilities for flood control management,
encompassing planning, maintenance, and construction of enhancements for regional facilities. This
includes managing facilities such as the Coachella Valley Stormwater Channel (CVSC, Whitewater River),
the La Quinta Evacuation Channel, the Bear Creek System, the East La Quinta Channel, and Lake
Cahuilla. CVWD is an independent special district that is responsible for protecting and conserving local
water resources in the CV. CVWD provides water to its customers via groundwater, recycled water, and
imported water from either the Colorado River (via Coachella Canal) or through the State Water Project
(CVWD, 2024). As groundwater is an important resource in the region, the CVWD has adopted several
strategies, including groundwater recharge, imported water utilization, and water conservation initiatives,
aimed at reducing groundwater extraction.
The Whitewater River/CVSC, which is managed by CVWD, serves as the primary drainage route within the
City and while usually dry, it can flood during storms. Spanning approximately 50 miles, the CVSC
averages 260 feet in width and is channelized in some portions and contains levees (City of La Quinta,
2022). The channel mostly aligns with its historical natural course, except for a deviation within the City's
boundaries.
The City maintains and manages stormwater-related facilities that gather and transport runoff from streets
and properties to regional channels and basins. The City's Master Drainage Plan serves as a tool for
managing and documenting the status and locations of existing stormwater management facilities (City of
La Quinta, 2009). The Project area includes regions identified by the Federal Emergency Management
Act's (FEMA's) National Flood Hazard Layer (NFHL) as Zone X and Zone A. Zone X denotes areas with a
reduced flood risk due to the presence of levees, while Zone A represents areas situated within the 100-
year floodplain (FEMA, 2024).
Compliance with the following policies outlined in the City's General Plan would promote efficient use and
conservation of the City's valuable water resources:
Policy WR-1.1: Support the Coachella Valley Water District in its efforts to supply adequate
domestic water to residents and businesses.
— Program WR-1.1.a: The City shall continue to implement its Water Efficient Landscaping
Ordinance and Building Codes, and update them as needed to meet or exceed State standards
for water efficiency and conservation.
— Program WR-1.1.b: Continue to work with CVWD to implement independent and joint
programs, rebates, and discounts that promote water conservation, subject to available
funding.
Policy WR-1.2: Support the Coachella Valley Water District in its efforts to recharge the aquifer.
— Program WR-1.2.a: Support CVWD's efforts to increase recharge at its La Quinta facility and
elsewhere in its district.
— Program WR-1.2.b: Work with CVWD to implement new or improved recharging techniques in
golf course and lake design, turf and agricultural irrigation methods, and the use of tertiary
treated water for irrigation and other uses.
Policy WR-1.3: Support the Coachella Valley Water District in its efforts to expand tertiary treated
(i.e. reclaimed) water distribution.
City of La Quinta Highway 111 Corridor Specific Plan 3-75
Environmental Analysis — Hydrology and Water Quality
— Program WR-1.3.a: Work with CVWD to provide tertiary treated water for future recreational
facilities and landscaping irrigation to the greatest extent possible.
Policy WR-1.4: Protect stormwater from pollution and encourage its use to recharge the aquifer.
— Program WR-1.4.a: Implement federal, regional and local standards pertaining to the discharge
and treatment of pollutants in surface water for all development projects.
— Program WR-1.4.b: Coordinate with CVWD in its review of projects which impact drainage
channels.
— Program WR-1.4.c: Require on -site retention for new development projects to the greatest
extent possible, to provide added recharge of the aquifer.
Policy WR-1.5: Development within drainage areas and stormwater facilities shall be limited to
recreational uses such as golf courses, lakes, sports or play fields and similar uses.
Policy WR-1.6: Encourage the use of permeable pavements in residential and commercial
development projects.
a) Violate any water quality standards or waste discharge requirements or otherwise
substantially degrade surface or ground water quality?
Less Than Significant with Mitigation Incorporated: Future development along the Highway 111
Corridor would lead to the construction of new structures. This expansion of mixed -use development and
densification of the Highway 111 Corridor would introduce more impermeable surfaces, as well as an
increase in population and vehicles. Consequently, there would be a rise in urban pollutants like oils, heavy
metals, pesticides, and fertilizers entering the storm drain systems.
The SWRCB regulates water quality through the NPDES program, established under the Clean Water Act.
This program aims to control and reduce pollutants entering water bodies from both point and non -point
sources, covering long-term and construction -related activities. NPDES permits for discharges to water
bodies are issued and enforced by the Colorado River RWQCB.
Projects that disturb more than one acre of land during construction must submit a notice of intent to be
covered under the NPDES General Permit for Storm Water Discharges Associated with Construction
Activity. Project applicants must propose control measures consistent with this permit, as well as with local
agency recommendations and RWQCB standards. Development that exceeds one acre in disturbance
requires a notice of intent submission to the RWQCB. The State NPDES General Construction Permit
mandates the development and execution of a SWPPP. This plan utilizes BMPs for controlling runoff,
erosion, and sedimentation from project sites, both during and after construction.
Adhering to the NPDES General Permit requirements would significantly mitigate potential impacts on water
quality to below a significant level. Additionally, any future development of wastewater treatment systems
could affect groundwater quality, however, treatment of wastewater must be in accordance with RWQCB as
well as state regulations. As such, impacts to surface waters or ground water quality can be reduced to a
less than significant level through the implementation of mitigation measure HWQ-1.
Mitigation Measures: HWQ-1.
City of La Quinta Highway 111 Corridor Specific Plan 3-76
Environmental Analysis — Hydrology and Water Quality
b) Substantially decrease groundwater supplies or interfere substantially with groundwater
recharge such that the project may impede sustainable groundwater management of the
basin?
Less Than Significant: CVWD manages and protects groundwater resources in the CV and implements
groundwater recharge to conserve water for the region. However, despite CVWD's consistent increase in
groundwater basin recharge (from 1,813 acre-feet in 2000 to 21,735 acre-feet in 2009), persistent drought
conditions and rising demand have prevented CVWD from sustaining positive recharge levels. CVWD
intends to intensify recharge endeavors as the City expands (City of La Quinta, 2022; CVWD, 2024). Future
development across the CV and the Highway 111 Corridor would necessitate domestic water for indoor use
and landscaping irrigation, which would likely result in an increased demand on constrained water
resources. The City has initiated water conservation measures and must sustain and broaden those efforts
to safeguard its water reserves in the future. The City is also working with property owners along the
corridor to remove non-functional turf and replace with desertscape to conserve water resources.
The proposed Specific Plan will enable future projects to use this impact analysis for environmental
assessments, providing a programmatic overview that will likely be tiered from this document. Future
growth and development along Highway 111 should align with the goals, policies, and programs outlined in
the City's General Plan, particularly water resource policies WR-1.1 through WR-1.6. Projects in the area
will need to adhere to water efficiency standards, including Building Code mandates, and should
incorporate drought -tolerant landscaping with minimal irrigation. These measures, along with other
applicable requirements, are expected to effectively mitigate water -related impacts to less than significant
levels.
Mitigation Measures: No mitigation measures required.
c.i) Substantially alter the existing drainage pattern of the site or area, including through the
alteration of the course of a stream or river or through the addition of impervious surfaces, in
a manner which would result in substantial erosion or siltation on- or off -site?
Less Than Significant: Development facilitated by this Specific Plan would likely involve grading and
construction in areas already developed, and undeveloped areas, potentially altering drainage patterns and
increasing impervious surfaces. This could lead to increased stormwater runoff, potentially causing erosion,
siltation, or exceeding the capacity of storm drain systems, thereby posing flood hazards to surrounding
lands. However, these impacts related to altered drainage patterns and stormwater runoff would remain
insignificant if future development adheres to the policies of the City's General Plan and complies with
existing federal, state, and local regulations. As such, impacts are anticipated to be less than significant.
Mitigation Measures: No mitigation measures required.
c.ii, c.iii) Substantially increase the rate or amount of surface runoff in a manner which would
result in flooding on- or off -site? Create or contribute runoff water which would exceed
the capacity of existing or planned stormwater drainage systems or provide substantial
additional sources of polluted runoff?
Less Than Significant with Mitigation Incorporated: The Specific Plan does not include specific site
designs, nor does it include development plans that may increase surface runoff rates and flooding. The
document is intended to guide future land use and propose development scenarios and aesthetic
improvements (Highway 111 Development Code) to the Highway 111 Corridor. However, potential future
improvements in the area covered by the Specific Plan may alter runoff rates, possibly causing flooding or
City of La Quinta Highway 111 Corridor Specific Plan 3-77
Environmental Analysis — Hydrology and Water Quality
exceeding the capacity of the drainage system. The Highway 111 Corridor is largely developed, and any
new buildings or facilities must be designed to manage stormwater by directing it into the City's drainage
system or retaining it onsite. Adhering to City's development standards would help mitigate impacts related
to surface runoff and drainage system overload. Furthermore, future improvements that disturb over one
acre of land would be required to develop and implement a SWPPP under NPDES (as mentioned above),
which would mitigate impacts associated with stormwater runoff on the environment. Moreover,
developments that generate more than 5,000 square feet of new impervious surface are generally required
to adhere to Water Quality Management Plan (WQMP) regulations, which call for post -construction controls
to manage stormwater runoff and safeguard water quality (RCFCWCD, 2015b). Finally, integrating General
Plan policy WR-1.6 into future construction and design along the Highway 111 Corridor would promote the
adoption of permeable pavements, thereby reducing stormwater impacts caused by runoff. Therefore,
impacts are expected to be less than significant with incorporation of Mitigation Measure HWQ-1.
Mitigation Measures: HWQ-1.
c.iv) Impede or redirect flood flows?
Less Than Significant: The Project area includes regions identified by FEMA's NFHL as Zone X and Zone
A. Zone X denotes areas with a reduced flood risk due to the presence of levees, while Zone A represents
areas situated within the 100-year floodplain. There are no FEMA-regulated floodways in the Project area
(FEMA, 2024). Future improvements in flood hazard areas would undergo City Engineer review to ensure
compliance with all development requirements. Future improvements would be required to prepare project -
specific hydrology studies and water quality management plans. Thus, adherence to City development
standards would mitigate impacts related to impeding or redirecting flood flows, and as such, impacts are
anticipated to be less than significant.
Mitigation Measures: No mitigation measures required.
d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project
inundation?
Less Than Significant: According to FEMA, the Whitewater River, located along the northern boundary of
the Project area, is classified as Zone A. Only a relatively small and select portion of the Project area
(approximately one acre area) is located within a flood hazard area (Zone A). This Zone A area is situated
along the Whitewater River channelized wash, which lies in the northwest portion of the Project area, where
Highway 111 crosses over the wash. However, the Project area outlined in this Specific Plan is an inland
area that is not near a large body of water that could release or carry pollutants from a tsunami or seiche.
As described above, any future development improvements along the Highway 111 Corridor would be
reviewed by City staff for compliance with flood hazard development standards. Additionally, future
development may be required to prepare project -specific hydrology and water quality management plans,
as needed, to align with City development standards. As such, impacts related to the potential release of
pollutants due to project inundation would be reduced and impacts are anticipated to be less than
significant.
Mitigation Measures: No mitigation measures required.
e) Conflict with or obstruct implementation of a water quality control plan or sustainable
groundwater management plan?
Less Than Significant with Mitigation Incorporated: As mentioned above, the City's Master Drainage
Plan documents the status and locations of all stormwater management facilities (City of La Quinta, 2009).
The Whitewater River Region Stormwater Management Plan outlines the activities and programs
City of La Quinta Highway 111 Corridor Specific Plan 3-78
Environmental Analysis — Hydrology and Water Quality
undertaken by permittees to effectively manage urban runoff in accordance with the NPDES municipal
separate storm sewer system (MS4) permit, specifically tailored for the Whitewater River Region
(RCFCWCD, 2015a). Additionally, the Whitewater River Region Water Quality Management Plan Guidance
Document was created to aid projects in meeting the obligations for addressing post -construction urban
runoff from new development and redevelopment projects within the region (RCFCWCD, 2015b).
Development planned within the Specific Plan area shall adhere to mitigation measure HWQ-2, which
includes water efficiency standards, compliance with development codes, and the use of drought -tolerant
landscaping and restricted irrigation methods. Compliance with these requirements would ensure that future
enhancements along the Highway 111 Corridor do not hinder the implementation of water quality control or
sustainable groundwater management plans. Therefore, impacts are anticipated to be less than significant
with mitigation incorporated.
Mitigation Measures: HWQ-2.
Hydrology and Water Quality Mitigation Measures
• HWQ-1: Stormwater Management Practices
Prior to the issuance of City building permits, all projects within the Specific Plan area that disturb
one acre or more of land must prepare a SWPPP. This plan shall outline suitable BMPs for
managing and treating runoff from future development site(s). The applicant is accountable for both
preparing and executing the SWPPP in accordance with NPDES requirements. Additionally, the
applicant must submit a Notice of Intent to the SWRCB, obtain a Waste Discharge ID Number
(WDID), and ensure a copy of the SWPPP is present at the development site throughout the
construction phase.
• HWQ-2: Water Conservation Measures
Future development in the Highway 111 Corridor must integrate water -saving appliances and
fixtures, such as low -flush toilets, low -flow showerheads, and faucets, in compliance with Section
17921.3 of the Health and Safety Code, Title 20 of the California Administrative Code Section
1601(b), and relevant sections of Title 24 of the California State Code. Additionally, the City would
enforce its Water Efficient Landscape ordinance, requiring development projects within the Specific
Plan area to adopt water -efficient landscaping plans that meet or exceed current criteria. These
measures are aimed at conserving water resources while addressing the needs of residents and
businesses.

Environmental Analysis — Land Use and Planning
3.11 Land Use and Planning
Would the project:
a) Physically divide an established community? ✓
b) Cause a significant environmental impact due to a
conflict with any land use plan, policy, or regulation ✓
adopted for the purpose of avoiding or mitigating
an environmental effect?
Highway 111, traversing the Project area, is recognized as a primary arterial route, featuring a width of six
lanes. The City's General Plan Land Use Designation for the Project area is GC. The Specific Plan would
continue to implement the mixed -use overlay district, as outlined in the General Plan. The overlay
strategically considers the area's ideal location, in close proximity to public facilities, commerce, and major
roads. By integrating mixed use development, the Specific Plan aims to create a dynamic blend of
commercial, residential, and recreational spaces that can serve the diverse needs of the community.
The Project encompasses enhancements to transportation infrastructure, featuring the integration of
dedicated bike lanes, enhancements to pedestrian pathways and potentially roundabouts at strategic points
of the corridor area. These upgrades aim to facilitate seamless connectivity along the corridor, fostering
smoother traffic flow and ensuring safer and more accessible travel options for all users. The proximity to
key transportation routes and essential services makes the Project area an ideal location for such
development, enhancing accessibility and convenience for residents and visitors alike. The implementation
of the Specific Plan is designed to create a more dynamic, interconnected, and sustainable urban setting,
aligning with the vision of a vibrant, pedestrian -friendly downtown center.
a) Physically divide an established community?
No Impact: The Specific Plan outlines seven DSAs that serve as a blueprint for future land use,
development standards, and design guidelines in accordance with the City's vision. Development would
occur within the existing boundaries of the City without physically dividing any existing neighborhoods in La
Quinta. The Specific Plan aims to transform the downtown area into a vibrant and pedestrian -friendly center
that serves as the focal point for the community. It envisions a walkable environment that encourages foot
traffic and creates a lively atmosphere. The proposed mix of land uses within the Specific Plan is designed
to be compatible with the existing uses in the surrounding downtown area and its main thoroughfares. This
compatibility ensures a harmonious integration of new developments with the established character and
activities of the immediate vicinity. The proposed Project would not physically divide any established
community and would result in a negligible impact on the surrounding area.
Mitigation Measures: No mitigation measures required.
b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or
regulation adopted for the purpose of avoiding or mitigating an environmental effect?
No Impact: The proposed Project would be consistent with the land use plans, policy and regulations set
forth by the City including the Land Use Element of the General Plan as well as the City's Municipal Code.
Consistency with the General Plan Goals and Policies:
City of La Quinta Highway 111 Corridor Specific Plan 3-80
Environmental Analysis — Land Use and Planning
The City's General Plan largely consists of a set of guidelines and policies that are in support of improved
land use. As per the General Plan, Highway 111 presents the City with a prime opportunity for targeted
diverse -purpose development, emphasizing increased housing choices and the creation of pedestrian -
friendly spaces that prioritize public accessibility. Highway 111's convenient access to transit options and its
proximity to employment centers, schools, and various services make it an ideal location for mixed -use
projects. This combination of factors creates a favorable environment for the integration of residential,
commercial, and possibly other uses, fostering a vibrant and interconnected community along Highway 111.
Within this framework, the vision of the Highway 111 Corridor Specific Plan aligns with the policies
established for La Quinta, particularly those related to land use. Therefore, any future project would need to
adhere to the goals, policies, and actions outlined in the General Plan to ensure consistency and
compliance with the established framework.
The Specific Plan would be consistent with the following relevant goals and implementation policies from
the General Plan Land Use Element:
Goal Land Use (LU)-5: A broad range of housing types and choices for all residents of the City.
— Implementation Policy LU-5.2 Consider changes in market demand in residential product type
to meet the needs of current and future residents.
■ Program LU-5.2a: Periodically review and update, as needed, the standards of the Zoning
Ordinance to allow for changes in residential product types without the need for a Specific

Highway 111 Specific Plan would adhere to its policies including:
Mixed Use Overlay District (9-110.120)
Purpose and intent:
— To provide opportunities for multifamily residential development in combination with
commercial and/or office development in a cohesive and integrated manner.
— To facilitate mixed use nodes that minimize vehicle trips and enhance proximity to services and
mass transit, consistent with implementation measures CI-13 and ND-4 of the City's GHG Plan,
as well as Transportation Demand Management principles.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-82
Environmental Analysis — Mineral Resources
3.12 Mineral Resources
Would the project:
a) Result in the loss of availability of a known mineral
resource that would be of value to the region and
the residents of the state?
b) Result in the loss of availability of a locally -
important mineral resource recovery site ✓
delineated on a local general plan, specific plan or
other land use plan?
a) Result in the loss of availability of a known mineral resource that would be of value to the
region and the residents of the state?
No Impact: According to the City's General Plan, the only mineral resources in the region are composed of
primarily sand and gravel for construction. However, these resources have not been mined in the City for
many years. The California DOC, Division of Mines and Geology, has conducted mapping of the City's
resources and recognized the presence of three mineral resource zones within the region:
MRZ-1 consists of land where no significant mineral deposits are present, or where it is judged that
little likelihood for their presence exists.
MRZ-2 consists of land where significant mineral deposits are present, or where it is judged that a
high likelihood for their presence exists.
MRZ-3 consists of land containing mineral deposits, but the significance cannot be evaluated from
available data.
The designated region outlined in the Specific Plan is labeled as MRZ-1, suggesting a low probability of
substantial mineral resources being present (City of La Quinta, 2022). Therefore, the loss of known mineral
resources is not expected and as such, impacts to mineral resources are not anticipated.
Mitigation Measures: No mitigation measures required.
b) Result in the loss of availability of a locally -important mineral resource recovery site
delineated on a local general plan, specific plan or other land use plan?
No Impact: No locally important mineral resource recovery site is located in the designated Project area
covered by the Specific Plan (City of La Quinta, 2022). Therefore, no impacts related to mineral resources
are anticipated.
Mitigation Measures: No mitigation measures required.

Environmental Analysis — Noise
3.13 Noise
Would the project:
a) Result in generation of a substantial temporary or
permanent increase in ambient noise levels in the
vicinity of the project in excess of standards
established in the local general plan or noise
ordinance, or applicable standards of other
agencies?
b) Result in generation of excessive groundborne
vibration or noise levels?
c) For a project located within the vicinity of a private
airstrip or an airport land use plan or, where such a
plan has not been adopted, within two miles of a
public airport or public use airport, would the
project expose people residing or working in the
project area to excessive noise levels?
Noise, considered an unwanted sound, can have severe physiological and psychological effects, including
sleep disturbances and hearing loss. Sound is typically measured in decibels (dB), which quantify changes
in air pressure. Traffic noise, however, is usually measured in A -weighted decibels (dBA) since this scale
aligns closely with human hearing. It emphasizes mid -range frequencies while giving less importance to
very low and very high frequencies, reflecting our natural experience of sounds like traffic. As most noise is
measured in dB, people notice a 3 dB increase in noisy areas, a 5 dB rise is clearly noticeable, and a 10 dB
increase feels like doubling the loudness. Traffic noise impacts are deemed significant if predicted levels
exceed existing noise by 12 dBA or approach within 1 dBA of the noise abatement criterion (NAC) for
sensitive areas, with evaluations considering the setting, receptor sensitivity, noise increase magnitude,
number of affected residences, and absolute noise level. In California, under Federal Highway
Administration (FHWA) protocol, the NAC is 67 dBA for residences, places of worship, and schools.
Construction activities and associated equipment can register up to 110 dBA (FHWA, 2024; City of La
Quinta, 2022).
Table 3.4 below illustrates the impact of loudness on people's subjective perception.

The ambient noise level in a community is the total background sound at any given time, including noise
from sources such as traffic, birdsong, conversations, and other environmental sounds. A linear source of
noise, such as a roadway, affects a broader area along its length, while a point source, like a factory
exhaust, impacts a more localized area around its specific location (USEPA, 1978). In the City, traffic noise
is the primary noise source, with levels rising when heavy trucks are more prevalent compared to
passenger cars. Other contributors include commercial activities such as air compressors, compactors,
landscaping equipment, and daily business operations. Additionally, aircraft noise from Jacqueline Cochran
Regional Airport, though infrequent, can impact nearby residential areas.
The City's General Plan includes the following policies to manage and reduce noise impacts from future
development:
• Policy N-1.1: Noise standards in the City shall be consistent with the Community Noise and Land
Use Compatibility scale described in this Element.
• Policy N-1.2: New residential development located adjacent to any roadway identified in Table IV-4
as having a build out noise level in excess of 65 d8A shall continue to be required to submit a
noise impact analysis in conjunction with the first Planning Department application, which
demonstrates compliance with the City's noise standards.
• Policy N-1.3: New non-residential development located adjacent to existing residential
development, sensitive receptors or residentially designated land, shall be required to submit a
noise impact analysis in conjunction with the first Planning Department application, which
City of La Quinta Highway 111 Corridor Specific Plan 3-85
Environmental Analysis — Noise
demonstrates that it will not significantly impact the adjacent residential development or residential
land.
• Policy N-1.4: All Mixed Use projects shall be required to submit a noise impact analysis in
conjunction with the first Planning Department application, which demonstrates compliance with
the City's noise standards.
• Policy N-1.5: All noise impact analysis will include, at a minimum, short-term construction noise
and noise generated by the daily operation of the project at build out.
• Policy N-1.6: The City may require remedial noise control plans and/or improvements for areas
experiencing noise in excess of adopted City standards.
• Policy N-1.7: Noise impact analysis shall be included in all City Capital Improvement Plan (CIP)
and developer -required roadway widening projects to demonstrate compliance with City noise
standards.
• Policy N-1.8: Maintain a truck route plan restricting truck travel to arterial roadways.
a) Result in generation of a substantial temporary or permanent increase in ambient noise
levels in the vicinity of the project in excess of standards established in the local general
plan or noise ordinance, or applicable standards of other agencies?
Less than Significant Impact with Mitigation Incorporated: In the City, traffic noise - especially from
heavy trucks - is the most prevalent source of noise, with additional noise coming from commercial activities
and daily operations. Section 9.100.210 of the La Quinta Municipal Code sets noise standards, allowing 60
dBA from 7 AM to 10 PM and 50 dBA from 10 PM to 7 AM for sensitive uses, and 75 dBA and 65 dBA,
respectively, for nonresidential areas. Construction projects often use heavy equipment that generates
noise between 68 dBA and over 100 dBA at 50 feet, with levels decreasing by about 6 dBA for each
doubling of distance. However, heavy equipment near sensitive areas can still cause brief periods of
excessive noise. To address this, the City's noise ordinance limits construction activities during evenings,
weekends, and holidays. To mitigate construction -related noise impacts associated with the Highway 111
Corridor Specific Plan, projects within the Specific Plan area shall implement NOI-1. Additionally,
developments near sensitive receptors would include a construction noise analysis.
The addition of mixed use and residential areas along Highway 111 is intended to create a vibrant,
interconnected, and pedestrian -friendly downtown. Future development, as outlined by the Specific Plan
may temporarily generate construction noise as well as increase longer -term operational noise along the
corridor Noise levels are anticipated to be compatible with the urban environment. For future developments
along the Highway 111 Corridor, the City may require a noise impact study. Based on this study, projects
may need to include noise mitigation measures as per General Plan policies NS-1.1 through NS-1.8,
ensuring that noise levels remain acceptable and impacts are minimal. Future development would follow
the City's Municipal Code and General Plan policies to ensure traffic noise remains within acceptable
levels, preventing exposure beyond these standards. As such, impacts are expected to be less than
significant.
Mitigation Measures: NOI-1.
b) Result in generation of excessive groundborne vibration or noise levels?
Less Than Significant Impact: None of the permitted uses in the proposed Specific Plan area involve
excessive vibration or groundborne noise. However, construction of future developments in the area may
temporarily cause short-term noise or vibration impacts. The City's General Plan notes that groundborne
vibration primarily comes from construction equipment, train activity, and heavy truck traffic. However,
City of La Quinta Highway 111 Corridor Specific Plan 3-86
Environmental Analysis — Noise
unlike noise, there is no standardized method for measuring vibration. In the City, most vibration is caused
by construction and heavy trucks, as there are no train tracks within the City or its surrounding areas. Over
time, the introduction of new vibration sources is not anticipated. While construction equipment and heavy
trucks may cause brief, localized vibrations, these are not expected to have a significant impact on the City.
The implementation of the Specific Plan would not directly increase groundborne vibration or noise levels.
Future development under the Plan would require additional CEQA review and noise/vibration analysis. As
such, impacts related to excessive groundborne vibration or noise levels are anticipated to be less than
significant.
Mitigation Measures: No mitigation measures required.
c) For a project located within the vicinity of a private airstrip or an airport land use plan or,
where such a plan has not been adopted, within two miles of a public airport or public use
airport, would the project expose people residing or working in the project area to excessive
noise levels?
No Impact: The Bermuda Dunes Airport is approximately 2.7 miles north of the study area and the
Jacqueline Cochran Regional Airport is situated in the community of Thermal approximately 8 miles
southeast of the Project area. The Bermuda Dunes Airport is a public use airport that is privately owned.
The Jacqueline Cochran Regional Airport is also a public use airport and primarily handle business and
private air traffic. As airport activity is expected to grow in the future, noise impacts would vary depending
on the runway used. One runway, aligned north -south, primarily generates noise to the north and south.
The other runway, oriented northwest -southeast, produces noise mainly around the immediate area.
Consequently, noise from the airport is not expected to impact areas west of Harrison Street, about 7 miles
southeast of the Specific Plan limits. Any future development along the Highway 111 Corridor would not be
affected by this airport as the Specific Plan area is northwest of this airport. Due to the distance from the
airport, the Specific Plan area is unlikely to experience excessive noise from airport operations. No impacts
would occur.
Mitigation Measures: No mitigation measures required.
Noise Mitigation Measures
• N0I-1: Noise Reduction
All construction activities shall adhere to the City Construction Hours/Quality Assurance Program for
designated construction hours, and equipment with internal combustion engines must be equipped
with manufacturer -recommended mufflers. Future development projects shall use noise -reducing
paving materials during temporary construction activities, such as open -grade asphalt, for all road
surfacing, as feasible.

Environmental Analysis — Population and Housing
3.14 Population and Housing
Would the project:
a) Induce substantial unplanned population growth in
an area, either directly (for example, by proposing
new homes and businesses) or indirectly (for ✓
example, through extension of roads or other
infrastructure)?
b) Displace substantial numbers of existing people or
housing, necessitating the construction of ✓
replacement housing elsewhere?
Currently, the City of La Quinta has a vibrant population (estimated at 40,000 residents), with expectations
of growth in the years ahead. As the City continues to attract new residents and businesses, there is a
pressing need to develop its areas thoughtfully, particularly focusing on sustainable practices. The Highway
111 Corridor, a central hub for commercial activities, is slated for development that integrates mixed -use
spaces and fosters walkability and connectivity. This approach aims to streamline City functions, ensuring
that as the City expands, it does so in a sustainable and community -oriented manner that enhances the
overall quality of life for its residents.
Through the implementation of the Specific Plan, the Highway 111 Corridor would integrate residential
development and mixed -uses alongside its current commercial development, promoting a community
design that prioritizes pedestrians and cyclists to enhance overall quality of life and mobility throughout the
City.
The City must participate in regional efforts mandated by Senate Bill 375 (SB 375), a California state law
focused on curbing urban sprawl, promoting sustainable community planning, and cutting down on vehicle
trips and air emissions to reduce greenhouse gases. This law mandates "Sustainable Community
Strategies" crafted by the Southern California Association of Governments (SCAG), aiming to promote
concentrated development, mixed -use areas near job centers, bus routes, and commercial services (City of
La Quinta, 2022).
The proposed Project's Development Moderate Scenario is projected to introduce around 1,000 residential
units (equivalent to 1,464,000 GSF) and approximately 339,000 GSF of additional retail, commercial, hotel,
restaurant, and civic spaces within the Specific Plan area. In contrast, the Specific Plan's Development Max
Scenario aims to incorporate roughly 1,600 residential units (totaling 1,837,000 GSF) and about 526,000
GSF of new retail, commercial, hotel, restaurant, and civic spaces into the area. The Development
Moderate Scenario estimates a total development of approximately 1,803,000 GSF, while the Development
Max Scenario estimates approximately 2,363,000 GSF — a 31.08% increase in developed area along the
Highway 111 Corridor. See Figure 1-3 and Figure 1-4 for more information on development area scenarios
and land use build out.
City of La Quinta Highway 111 Corridor Specific Plan 3-88
Environmental Analysis — Population and Housing
a) Induce substantial unplanned population growth in an area, either directly (for example, by
proposing new homes and businesses) or indirectly (for example, through extension of
roads or other infrastructure)?
Less than Significant Impact: The Specific Plan is intended to provide guidance for the organized
development and redevelopment of local infrastructure, businesses, and housing along the Highway 111
Corridor. The City aims to create a cohesive blueprint that integrates shopping, living, working, and
recreational spaces in one interconnected area. This space would be accessible through Highway 111, the
CV Link, and other multi -use paths. The implementation of the Specific Plan is expected to take place
gradually over a period of 20 to 25 years. If economically feasible, the completion of Specific Plan build out
could result in an additional residential area from 1,464,000 GSF (Development Moderate Scenario) to
1,837,000 GSF (Development Max Scenario) for the Highway 111 Corridor. Moreover, including residential
units along the Highway 111 Corridor would create housing opportunities in an area traditionally focused on
commercial activities, thereby introducing a more diverse and beneficial mix of uses in the region in a
sustainable manner.
As a guidance document, the proposed Specific Plan does not contain detailed designs or specific
proposals for particular sites, nor does it provide authorization for any development activities. Nevertheless,
potential enhancements within the Specific Plan area could involve the construction of new residential or
commercial properties, which may result in a direct or indirect population increase within the designated
area. Even if all the residential, commercial, and hotel developments envisioned by the Specific Plan were
built, the population growth associated with these developments would occur gradually over an extended
period. Furthermore, any future improvements would likely reference and tier off of this CEQA document to
evaluate potential impacts related to population growth and development. Therefore, the overall impact on
population growth would be deemed less than significant.
Mitigation Measures: No mitigation measures required.
b) Displace substantial numbers of existing people or housing, necessitating the construction
of replacement housing elsewhere?
Less than Significant Impact: The proposed Project area along the Highway 111 Corridor is currently
zoned primarily for commercial purposes, featuring shopping centers, restaurants, and office spaces. This
area has traditionally focused on big box retail with limited residential options. However, the proposed
Project aims to increase residential opportunities in alignment with the La Quinta General Plan and
Municipal Code. This approach ensures that the Specific Plan would not displace individuals or housing but
rather diversify land use to accommodate additional residential development. Given its inefficient use of
space and sprawling commercial developments, the Highway 111 Corridor presents an opportunity to
improve its walkability and accessibility. The proposed development outlined in the Specific Plan seeks to
revitalize the area by drawing more people and optimizing land use in the region, thereby encouraging a
more dynamic and accessible environment. By promoting land use types that support residential growth,
the Specific Plan mitigates potential significant impacts on population resulting from the proposed
development scenarios and improvements along the Highway 111 Corridor. As such, impacts are
anticipated to be less than significant.
Mitigation Measures: No mitigation measures required.

Highway 111 serves as a crucial arterial corridor in the City of La Quinta, facilitating essential routes for
emergency services and access to public facilities. It not only connects the northern residential
neighborhoods with the bustling southern commercial core but also links other residences, schools, and
public facilities along its path. Highway 111 intersects with Washington Street, a prominent north -south
thoroughfare within the City that links Highway 111 to the Civic Center Campus located to the south. Public
facilities encompass City -owned buildings such as City Hall, the Library, and the Senior Center, which
collectively form the Civic Center Campus. Additionally, facilities include schools operated by either the
Desert Sands Unified School District or the Coachella Valley Unified School District. The City is supported
by the Riverside County Fire Department (RCFD), offering fire protection and emergency medical services
not only to the City itself but also to neighboring areas within Riverside County. Law enforcement services
and the protection of public safety are overseen by the Riverside County Sheriffs Department (RCSD).
The City features 12 parks that offer a variety of recreational activities and amenities, ensuring both
residents and visitors have numerous opportunities for outdoor enjoyment and community gatherings (City
of La Quinta, 2022). However, there are no parks located within the Specific Plan area. Most of the City's
parks and greenspaces are located outside the Highway 111 Corridor; this route acts as a vital connection,
allowing residents to seamlessly access these recreational areas beyond the urban commercial core.
Residents of the City currently enjoy access to 72 acres of parks, 146.75 acres of nature preserves with
recreational parkland, and 845 acres of regional parks. The City also has joint use agreements with Desert
Sands, neighboring cities, and the Desert Recreation District for the use of additional recreation facilities
(City of La Quinta, 2022).
The proposed development under this Specific Plan seeks to enhance connectivity throughout the City,
transforming Highway 111 from a principally vehicular thoroughfare into a unified, integrated corridor for
active transportation. The emphasis would be on fostering mixed -use developments that cater to pedestrian
and multimodal transportation needs, thereby creating a cohesive urban environment. This approach aims
City of La Quinta Highway 111 Corridor Specific Plan 3-90
Environmental Analysis — Public Services
to blend residential, commercial, and recreational spaces seamlessly, promoting a more vibrant and
accessible cityscape.
As development progresses along the Highway 111 Corridor, there may be heightened demand for fire
protection, emergency services, and public facilities, including parks. This growth could necessitate the
hiring of additional staff and the construction of new facilities to adequately support the expanding corridor.
The General Plan's Emergency Services Element, Public Facilities Element, and Parks and Recreation
Element specifically address future requirements for fire, emergency response, and public amenities.
a) Would the project result in substantial adverse physical impacts associated with the
provision of new or physically altered governmental facilities, need for new or physically
altered governmental facilities, the construction of which could cause significant
environmental impacts, in order to maintain acceptable service ratios, response times or
other performance objectives for public services?
Less Than Significant Impact: Possible improvements within the designated Specific Plan area might
entail the development of new or expanded residential or commercial properties, potentially leading to a
population increase, either directly or indirectly. This may increase the demand for the following public
services:
1. Fire Protection and Emergency Services: The proposed Project is aimed at promoting
development, which could lead to a rise in demand for fire protection services. As a result, there
would likely be a need for both additional personnel and new facilities to accommodate the
anticipated growth in the Specific Plan area. The City's General Plan acknowledges the need for
expanded fire protection services to meet demands associated with future population growth.
Although strategic placement of fire stations is present, additional fire stations would likely be
needed in areas where growth occurs (City of La Quinta, 2022). Future development under the
Specific Plan could increase the need for additional fire protection and emergency services. Impacts
are anticipated to be less than significant as future development would be required to pay
Development Impact Fees (DIF) to help offset impacts to fire and emergency services and would be
required to be consistent with the following policies from the City's General Plan:
Policy ES-1.1: The City shall continue to work with the Riverside County Fire Department to
accurately forecast future needs and provide adequate and timely expansion of services and
facilities based on service capabilities and response times.
- Program ES-1.1a: Maintain the Fire Facilities component of the City's Development Impact
Fee to assure that new development pays its fair share of future fire stations.
Policy ES-1.2: New Development proposals shall continue to be routed to the Fire Department
to assure that project access and design provide for maximum fire and life safety.
Program ES- 1.8a: Periodically review and update the Emergency Operations Plan to address
the City's growth in population and built environment, as well as new emergency response
techniques.
2. Police Protection: The development proposed in the Specific Plan could act as a catalyst for
growth, potentially increasing the demand for police protection services. Therefore, there may be a
necessity for additional personnel and the construction of new police facilities to adequately
accommodate the growth along the Highway 111 Corridor. The City's General Plan acknowledges
the potential need for increased police protection services to accommodate population growth. The
City follows the standard of one police officer per 1,000 residents (City of La Quinta, 2022). Should
City of La Quinta Highway 111 Corridor Specific Plan 3-91
Environmental Analysis — Public Services
future development prompted by this Specific Plan result in a rise in residential units and population,
additional officers may be necessary. Impacts on police protection services are expected to be less
than significant as future development would be required to pay DIF fees to help offset impacts to
police services and development would be required to be consistent with the following policies from
the City's General Plan:
Policy ES- 1.5: The City shall continue to work with the Riverside County Sheriff's Department
to accurately forecast future needs and provide adequate and timely expansion of services
and facilities.
Policy ES- 1.6: New development proposals shall continue to be routed to the Police
Department to assure that project access and design provide for defensible space and
maximum crime prevention while maintaining City design standards and codes.
3. Schools: Local schools are managed by two public school districts that offer education from
kindergarten through Grade 12: the Desert Sands Unified School District and the Coachella Valley
Unified School District (City of La Quinta, 2022). The Desert Sands Unified School District currently
serves the corridor area. Although there are no public schools from these districts in the Specific
Plan area, population growth, including an increase in school age children, is possible with
development facilitated by the Specific Plan. The anticipated population growth could increase the
demand for school services and potentially create the need for new or physically altered school
facilities. Schools could be built on properties near the Highway 111 Corridor or on sites within the
corridor that are served by existing infrastructure. Future development within the corridor area would
be required to pay school fees, in the amount set at the time of building permit issuance, to offset
any impacts created by additional residential units. As such, impacts on schools are anticipated to
be less than significant.
The Specific Plan would be consistent with the following policies from the City's General Plan:
Policy PF-1.6: The City shall coordinate with the Desert Sands and Coachella Valley Unified
School Districts and encourage the Districts to plan for and construct new schools to meet
demand.
4. Parks: No parks are located within the Specific Plan area; however, the CV Link is a multi -modal
trail system that runs along the Whitewater River at the north boundary of the corridor area and
would be available for new residents and patrons in the corridor. It is assumed that population
growth would result in an increase in demand for neighborhood and regional parks and other
recreational facilities. This Specific Plan supports the creation of additional recreational spaces and
pocket parks along the Highway 111 Corridor and a trail connector along the northern side of
Highway 111 to connect with the CV Link. The proposed development outlined by this Specific Plan
would enhance and potentially expand recreational facilities within the City without causing impacts
beyond those anticipated by the City's General Plan. The City's General Plan includes goals and
policies to maintain current parks and facilities and to acquire additional parkland for future
population growth, as listed below. Section 3.16, Recreation, provides a more detailed overview of
the City's recreational assets.
The Specific Plan would be consistent with the following policies from the City's General Plan:
Goal PR-1: A comprehensive system of parks and recreation facilities and services that meet
the active and passive needs of all residents and visitors.
Policy PR-1.1 Expand or modify community services to meet the health, well-being, and
recreational needs of the community.
City of La Quinta Highway 111 Corridor Specific Plan 3-92
Environmental Analysis — Public Services
• Policy PR-1.2: Continue to provide a minimum standard of 5 acres of parkland for every 1,000
residents.
• Policy PR- 1.3: Identify all viable financing mechanisms for the funding of construction,
maintenance, and operation of parks and recreational facilities.
• Policy PR- 1.4: The design and construction of parks and recreational facilities shall comply
with all the development standards that apply to privately constructed facilities.
• Policy PR- 1.5: Coordinate with partner agencies and neighboring communities to expand
recreational opportunities and access to recreational facilities.
• Policy PR- 1.6: Encourage patterns of development that promote safe pedestrian and bicycle
access to schools, public parks, and recreational areas.
• Policy PR-1.7: Identify opportunities to integrate public health concerns into parks and trails
planning.
• Policy PR- 1.8: Promote a healthy and active lifestyle for all residents.
5. Other Public Facilities: Public facilities include City -owned buildings, such as City Hall, the
Wellness Center, and the Library, also known as the Civic Center Campus. The General Plan
acknowledges that an increase in population would likely require the expansion of public facilities to
serve the City's anticipated future growth. The City's CIP is updated annually and would play a key
role in the planning and construction of future facilities (City of La Quinta, 2022). Future
development would be subject to DIF fees which would offset impacts to public facilities
Additionally the Specific Plan would be consistent with the following policies from the City's General
Plan:
• Policy PF-1.1: The City shall expand or modify municipal services to meet the needs of the
community.
• Policy PF-1.2: Periodically evaluate the demand for municipal services and facilities, and
include construction and expansion of these facilities to assure timely completion.
• Policy PF-1.3: The City shall identify all viable financing mechanisms for the funding of
construction, maintenance and operation of municipal facilities.
• Policy PF-1.4: The design and construction of municipal facilities shall comply with all the
processes and development standards that apply to privately constructed facilities.
• Policy PF-1.5: The City shall coordinate with the County of Riverside to assure that library
facilities and services are expanded as demand warrants.
• Policy PF-1.6: The City shall coordinate with the Desert Sands and Coachella Valley Unified
School Districts and encourage the Districts to plan for and construct new schools to meet
demand.
• Policy PF-1.7: The City shall continue to explore the potential for the joint purchase or use of
recreational facilities with the Desert Sands and Coachella Valley Unified School Districts, as
well as the Coachella Valley Recreation and Park District.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-93
Environmental Analysis — Recreation
3.16 Recreation
Would the project:
a) Increase the use of existing neighborhood and
regional parks or other recreational facilities such
that substantial physical deterioration of the facility
would occur or be accelerated?
b) Include recreational facilities or require the
construction or expansion of recreational facilities,
which might have an adverse physical effect on the
environment?
The City currently operates 12 City parks, the Civic Center Campus, and three nature preserve areas. La
Quinta Park is the closest park to the Project area outlined in this Specific Plan. Most City parks have
children's playground facilities, and the nature preserves offer hiking and bicycling trails for public
recreation. The CV Link is currently under construction which would provide a multi -modal trail for La Quinta
and CV residents. In addition, many existing subdivisions include public pocket parks. Two regional parks —
La Quinta Community Park (6.5 acres) and Lake Cahuilla Regional Park (845 acres) — are managed by the
Desert Recreation District and Riverside County Parks Department, respectively. Lake Cahuilla Regional
Park charges user fees for day visitors, fishing, and camping. The City collaborates with the Desert Sands
Unified School District to share recreational facilities on school grounds, such as the Sports Complex at La
Quinta Middle School and soccer fields at Colonel Mitchell Paige Middle School. The City is also home to
one public and 22 privately owned and operated golf courses, with seven courses available for public use.
In total, La Quinta has approximately 5,259 acres designated as recreational open space (City of La Quinta,
2022).
a) Increase the use of existing neighborhood and regional parks or other recreational facilities
such that substantial physical deterioration of the facility would occur or be accelerated?
Less Than Significant Impact: The objective of the proposed Specific Plan is to offer a clear direction for
the systematic development and redevelopment of local infrastructure, businesses, and housing. This may
lead to a population increase, which may increase the use of existing neighborhood and regional parks and
other recreational facilities. However, by adhering to the City's General Plan, which recognizes that a
population increase would necessitate the expansion of public facilities to accommodate growth, no
substantial physical deterioration of such facilities would occur (City of La Quinta, 2022). The Parks and
Recreation Element of the General Plan identifies current and projected demand for parks as the City
grows. Adherence to the City's General Plan would ensure that existing park and recreational facilities are
expanded in parallel with population increases. Therefore, impacts on neighborhood and recreational
facilities are anticipated to be less than significant.
Relevant Policies from the General Plan:
Policy PR- 1.1 through PR- 1.8
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-94
Environmental Analysis — Recreation
b) Include or require the construction or expansion of recreational facilities, which might have
an adverse physical effect on the environment?
Less Than Significant Impact: Population growth resulting directly or indirectly from the implementation of
development scenarios in the Specific Plan may necessitate the construction or expansion of recreational
facilities. The Quimby Act, also known as the Quimby Act of 1975 (California Government Code Sections
66477-66484), mandates that local governments require developers to either dedicate land or pay fees for
park and recreational purposes when subdividing land or securing a residential development permit. The
Act's aim is to guarantee sufficient park and recreational facilities and accompany new residential
developments, thereby balancing urban expansion with the demand for public open spaces. The Quimby
Act empowers local governments to manage the impact of new residential projects on community parks and
recreational amenities.
The Quimby Act sets a minimum threshold of 3.0 acres of parklands per 1,000 residents; however, the City
has a policy of providing a minimum of 5.0 acres of open space per 1,000 residents. The General Plan
acknowledges that expansion of recreational facilities would be needed as the City grows and would be
regularly updating the City's Community Service Master Plan to consider a growing demand for services
well in advance of need. By adhering to the Land Use, Natural Resources and Parks and Recreational
Elements of the City's General Plan, as well as the Community Service Master Plan, impacts to recreational
facilities are expected to be less than significant.
Relevant Policies from the General Plan:
Policy PR- 1.1 through PR- 1.8
Mitigation Measures: No mitigation measures required.

Roadways
Highway 111
The Highway 111 Corridor is a six -lane roadway that accommodates upwards of 28,700 vehicles daily
(Replica: Hwy 111 WB W/O Washington St, 2023). Within the study area, Highway 111 has a six -lane
divided cross-section with 50-mph posted speed limits. There are eight signalized intersections, located at
Highway 111 and Washington Street, Simon Drive, La Quinta Center Drive, Adams Street, La Quinta Drive,
Dune Palms Road, Costco Drive, and Jefferson Street. Dedicated left turn lanes are provided at all
signalized intersections, with nearly all providing dedicated right turn lanes as well.
Highway 111 serves as a primary east -west connection through the CV between the City of La Quinta and
communities to the northwest, including Palm Springs, Cathedral City, Rancho Mirage, Palm Desert, and
Indian Wells, and communities to the southeast, including Indio, Coachella, and communities surrounding
the Salton Sea and the Imperial Valley.
Washington Street
Within the study area, Washington Street is a divided six -lane major arterial with a landscaped median, with
three left turn lanes and right turn pockets in both directions respectively at the intersection with Highway
111. This portion of Washington Street has a 50-mph posted speed limit and accommodates upwards of
17,900 vehicles daily (Replica: Washington St NB S/O Hwy 111, 2023). Washington Street does not
accommodate on -street parking, as the surrounding land use is inward -facing residential and surface lot -
facing retail. Signage instructs bicyclists to share the sidewalk on the east side of Washington Street with
pedestrians.
Ad;;mG Strppt
Within the study area, Adams Street is a divided four -lane secondary arterial with a landscaped median
between Highway 111 and Avenue 48, with two left turn lanes and right turn pockets in both directions
respectively at the intersection with Highway 111. This portion of Adams Street has a 45-mph posted speed
limit and accommodates upwards of 3,540 vehicles daily (Replica: Adams St NB N/O Hwy 111, 2023).
Adams Street does not accommodate on -street parking due to lane configuration and widths north of
City of La Quinta Highway 111 Corridor Specific Plan 3-96
Environmental Analysis — Transportation
Highway 111 and the presence of Class II bike lanes, both buffered and non -buffered, south of Highway
111.
Dune Palms Road
Within the study area north of Highway 111, Dune Palms Road is an undivided four -lane secondary arterial
with two left turn lanes and a right turn pocket at the intersection with Highway 111. South of Highway 111,
Dune Palms Road is a divided four -lane arterial with two left turn lanes and a right turn pocket at the
intersection with Highway 111. This portion of Dune Palms Road has a 45-mph posted speed limit and
accommodates upwards of 2,890 vehicles daily (Replica: Dune Palms Rd NB N/O Hwy 111, 2023). Dune
Palms Road does not accommodate on -street parking between Highway 111 and Avenue 48 as there are
Class II bike lanes on either side. Partial Class II bike lanes and adjacent land use preclude on -street
parking north of Highway 111.
Jefferson Street
Within the study area, Jefferson Street is a divided six -lane major arterial with a landscaped median, with
three left turn lanes and right turn pockets in both directions respectively at the intersection with Highway
111. This portion of Jefferson Street has a 55-mph posted speed limit and accommodates upwards of
18,300 vehicles daily (Replica: Jefferson St SB N/O Hwy 111, 2023). Jefferson Street does not
accommodate on -street parking due to the presence of Class II bike lanes.
Bicycle & Pedestrian Facilities
With the suburban nature of the City of La Quinta, multimodal infrastructure is available, including sidewalk
and bicycle lanes along and adjoining Highway 111, however, it is often disconnected and distances
between destinations are spread out due to the auto -oriented land use patterns along the corridor. Within
the study area, pedestrian infrastructure is located along both sides of Highway 111, apart from segments
with sidewalk gaps along undeveloped parcels, including east of La Quinta Drive (north side) and east of
Dune Palms Road (north side). Sidewalks are most often 8 feet wide, exhibit serpentine alignment, and are
separated from motor vehicle traffic by landscape buffers. Crosswalks are provided at signalized
intersections of Highway 111/Washington Street (east side only), Highway 111/Simon Drive, Highway
111/La Quinta Center Drive, Highway 111/Adams Street, Highway 111/La Quinta Drive, Highway 111/Dune
Palms Road, Highway 111/Costco Drive (east side crossing only), and Highway 111/Jefferson Street.
Existing bicycle facilities are sporadic and disconnected, with most portions of Highway 111 containing
some form of bicycle facilities in at least one direction, but few, if any, connected to form a complete
segment. Class II bicycle lanes are provided along portions of Highway 111 west and east of Washington
Street (eastbound only), east of Simon Drive (eastbound only), east of La Quinta Center Drive (eastbound
only), west of Adams Street (westbound only), between Adams Street and Dune Palms Road (both
directions), and between Dune Palms Road and Jefferson Street (westbound only). Due to the number of
vehicle lanes, high speeds, and bike infrastructure lacking physical separation between active modes and
motor vehicles, the segment level of traffic stress on nearly all study area roadways is LTS 4 or LTS 3.
Segment LTS 1 is found on Simon Drive and La Quinta Center Drive due to fewer lanes and slower speeds.
Construction is ongoing for the planned CV Link project, an alternative transportation project connecting
eight cities and two tribes in the CV, providing a regional multi -use path for bicycles and pedestrians that
parallels the Highway 111 Corridor to the north throughout the Specific Plan area. The CV Link would
provide an alternative to automobile travel for residents and visitors, reducing vehicle trips and vehicle miles
traveled (VMT) and providing alternative mobility options for people of all ages and abilities.
City of La Quinta Highway 111 Corridor Specific Plan 3-97
Environmental Analysis
Public Transit
Existing regional transit routes in the study area include Route 1 EV, Route 7, Route 700, and Route 701, all
operated by SunLine Transit Agency. Route 1 EV runs on Highway 111, connecting Town Center Way in
Palm Desert (and connecting transit routes, like Route 1 WV) with the City of Coachella. Route 7 provides
transit service between the communities of Bermuda Dunes and La Quinta, connecting with the Highway
111 Corridor along Adams Street. Routes 700 and 701 are school "tripper buses" providing supplemental
transit service to and from La Quinta High School on school days.
Airports
The Bermuda Dunes Airport is a public use airport located along Avenue 42 adjacent to the Jefferson
Street/1-10 interchange approximately 2.7 miles north of the study area. Additionally, the Jacqueline
Cochran Regional Airport is approximately 8 miles southeast of the study area in Thermal, California.
a) Conflict with a program plan, ordinance or policy addressing the circulation system,
including transit, roadway, bicycle and pedestrian facilities?
No Impact: The Highway 111 Corridor Specific Plan includes urban design concepts that outline the
proposed streetscape enhancements envisioned for the Highway 111 Corridor area. The Specific Plan
would potentially increase traffic in the area along Highway 111. The CV Link's proximity to Highway 111
brings several advantages. First and foremost, it allows for enhanced accessibility, with multiple access
points and entryways along the route, making it convenient for users to connect to various neighborhoods,
businesses, parks, and other points of interest throughout the region. Additionally, being closely aligned
with the highway can increase visibility and awareness, promoting the usage of the pathway among the
public.
The Project proposes several complete street improvements in the study area to create a multimodal
corridor that is safe and comfortable for all users. Transportation improvements include reduced vehicular
travel lane widths, signs, and pavement markings, enhanced bicycle and pedestrian facilities like Class II
bike lanes, green conflict striping, widened sidewalks, curb extensions (bulb -outs), high visibility crossing
treatments, and reduced vehicular conflict zones. Additionally, the Specific Plan would be consistent with
the City's General Plan Circulation Goal, CIR-1, as outlined below:
CIR-1: A transportation and circulation network that efficiently, safely and economically moves
people, vehicles, and goods using facilities that meet the current demands and projected needs of
the City.
Mitigation Measures: No mitigation measures required.
b) Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)?
No Impact: The Highway 111 Corridor Specific Plan is not anticipated to conflict with CEQA Guidelines
Section 15064.3 criteria for analyzing transportation impacts effective July 1, 2020 concerning VMT.
The VMT screening described below meets the requirements stipulated by CEQA Guidelines Section
15064.3 (b) and incorporates relevant advice contained in the Technical Advisory on Evaluating
Transportation Impacts in CEQA published by the Governor's Office of Planning & Research (OPR) in
December 2018. Section 15064.3 of the State CEQA Guidelines describes the requirements for assessing
transportation impacts based on VMT that applied statewide beginning July 1, 2020. As described in
Section 15064.3:
City of La Quinta Highway 111 Corridor Specific Plan 3-98
Environmental Analysis
"Vehicle miles traveled" refers to the amount and distance of automobile travel "attributable to a
project." Other relevant considerations may include the effects of the project on transit or
nonmotorized travel. As described separately in the Technical Advisory on Evaluating
Transportation Impacts in CEQA (OPR, December 2018), VMT re-routed from other origins or
destinations as the result of a project would not be attributable to a project except to the extent that
the re-routing results in a net increase in VMT. For example, OPR guidelines note that retail
projects typically re-route travel from other retail destinations, and therefore a retail project may
lead to increases or decreases in VMT, depending on previously existing travel patterns. Similarly,
a large share of retail trips are "pass -by trips" that would not be considered attributable to a retail
project.
Lead agencies have discretion to choose the most appropriate methodology to evaluate a project's
vehicle miles traveled, including whether to express the change in absolute terms, per capita, per
household, or any other measure.
If existing models or methods are not available to estimate the vehicle miles traveled for the
particular project being considered, a lead agency may evaluate the project's vehicle miles
traveled qualitatively.
A lead agency may use models to estimate a project's vehicle miles traveled and may revise those
estimates to reflect professional judgment based on substantial evidence.
VMT Screening
The City's Vehicle Miles Traveled Analysis Policy indicates that residential and office projects located within
a low VMT-generating area may be presumed to have a less than significant impact absent substantial
evidence to the contrary. In addition, other employment -related and mixed -use land use projects may
qualify for the use of screening if the project can reasonably be expected to generate VMT per resident, per
worker, or per service population that is similar to the existing land uses in the low VMT area.
The Highway 111 Corridor Specific Plan covers multiple Traffic Analysis Zones (TAZs) of the Riverside
County Transportation Model (RIVTAM/RIVCOM), including TAZ 913, 920, 926, 929, 930, and 937. Based
on the model, the citywide VMT per Capita is 14.98 while the VMT for the Specific Plan area TAZs are as
follows:
• TAZ 913: 12.92
• TAZ 920: 12.50
• TAZ 926: 12.74
• TAZ 929: 0.00
• TAZ 930: 11.45
• TAZ 937: 0.00
The VMT for each TAZ is lower than the City threshold for the base year (2018). Based on these findings,
the Specific Plan does not require a VMT analysis as there is no impact.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-99
Environmental Analysis
c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or
dangerous intersections) or incompatible uses (e.g., farm equipment)?
No Impact: The Highway 111 Corridor Specific Plan is not anticipated to substantially increase hazards
due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses
(e.g., farm equipment).
The Highway 111 Corridor Specific Plan recommends the implementation of protected intersections, curb
extensions, lane width reductions, turn lane reductions, Class II bike lanes with green conflict markings,
high -visibility crosswalks, and Class I shared -use paths along the Highway 111 Corridor. Transportation
improvements along other key corridors in the study area include roundabouts, curb extensions, reduced
lane widths, Class II bike lanes with green conflict markings, and high -visibility crosswalks. With these
recommended infrastructure improvements, the Specific Plan aims to reduce hazards by reducing
pedestrian crossing distances, providing high visibility crossing treatments, and reducing vehicular conflict
zones.
The General Plan includes policies that would ensure efficient circulation and adequate access are
provided in the City. Future development under the Highway 111 Corridor Specific Plan, as part of the City's
project approval process, would be required to comply with existing regulations, including General Plan
policies and zoning regulations that have been prepared to minimize impacts related to design features.
Adherence to state and City requirements, combined with compliance with the City's General Plan and
zoning regulations, would ensure that the adoption of the proposed Highway 111 Corridor Specific Plan
would result in no impact with respect to an increase in hazards due to a geometric design feature or
incompatible uses.
Mitigation Measures: No mitigation measures required.
d) Result in inadequate emergency access?
No Impact: The Highway 111 Corridor Specific Plan is not anticipated to result in inadequate emergency
access. The Highway 111 Corridor Specific Plan proposes mixed -use development along the corridor,
enhancing pedestrian and bicycle access, implementing parking solutions, and increasing the density of
residential and commercial spaces. This aims to foster a more connected and community -centered
downtown area. Roadway improvements proposed under the Specific Plan would enhance the connectivity
and mobility of the downtown area and would not impede emergency vehicle access. As previously stated,
transportation improvements along the Highway 111 Corridor focus on enhancing safety for pedestrians
and vehicles through improved visibility at crosswalks and minimizing areas of vehicular conflict.
Furthermore, the City's General Plan includes policies that would ensure adequate emergency access.
Future development within the Highway 111 Corridor Specific Plan, as part of the City's project approval
process, must adhere to current regulations. These include General Plan policies and zoning regulations
specifically designed to mitigate impacts concerning emergency access. The City, throughout the multi -year
buildout period of the Highway 111 Corridor Specific Plan, would ensure relevant coordination with local
emergency response providers. Adherence to state and City requirements, combined with compliance with
the City's General Plan and zoning regulations, would ensure that the adoption of the proposed Specific
Plan would result in no impact with respect to inadequate emergency access.
Mitigation Measures: No mitigation measures required.

3.18 Tribal Cultural Resources
Would the project:
a) Cause a substantial adverse change in the
significance of a tribal cultural resource listed or
eligible for listing in the California Register of ✓
Historic Resources, or in a local register of historic
resources as defined in Public Resources Code
section 5020.1(k)?
b) Cause a substantial adverse change in the
significance of a tribal cultural resource that is a
resource determined by the lead agency, in its
discretion and supported by substantial evidence,
to be significant pursuant to the criteria set forth in
subdivision (c) of the Public Resources Code ✓
section 5024.1? In applying the criteria set forth in
subdivision (c) of the Public Resources Code
section 5024.1, the lead agency shall consider the
significance of the resource to a California Native
American Tribe.
The La Quinta area is home to the Desert Cahuilla Indians, who were the first ancestors of the La Quinta
area, settling into the Martinez Canyon in the early 1800s (SCTCA, 2024).
The CEQA Guidelines define a tribal cultural resource as: (1) a site, feature, place, cultural landscape,
sacred place, or object with cultural value to a California Native American Tribe that is listed or eligible for
listing on the California Register of Historical Resources, or on a local register of historical resources as
defined in Public Resources Code Section 5020.1(k); or (2) a resource determined by the Lead Agency, in
its discretion and supported by substantial evidence, to be significant according to the historical register
criteria in Public Resources Code Section 5024.1(c), and considering the significance of the resource to a
California Native American Tribe.
AB 52 established a formal consultation process for California tribes within the CEQA process. AB 52 must
be completed before a CEQA document can be certified. AB 52 specifies that any project may affect or
cause a substantial adverse change in the significance of a tribal cultural resource that would require a lead
agency to "begin consultation with a California Native American Tribe that is traditional and culturally
affiliated with the geographic area of the proposed Project." Section 21074 of AB 52 also defines a new
category of resources under CEQA called "tribal cultural resources." Tribal cultural resources are defined as
"sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California
Native American Tribe" and is either listed on or eligible for the California Register of Historic Resources
(CRHR) or a local historic register, or if the lead agency chooses to treat the resource as a tribal cultural
resource. California Native American Tribes to be included in the process are those that have requested
notice of projects proposed within the jurisdiction of the Lead Agency.
Native American Consultation
On March 14, 2024, the City initiated the tribal consultation process for the purposes of AB 52, in
conjunction with SIB 18 consultation for the Specific Plan, for the proposed Project. Initial consultation letters
were sent to all of the Native American tribal governments listed on the NAHC contact list, per the City's AB
City of La Quinta Highway 111 Corridor Specific Plan 3-101

52 protocol (Appendix C: Cultural Resources). The letters provided a summary of the Project and requested
information regarding comments or concerns the tribal governments might have regarding the proposed
Project. Letters were sent to the following tribal governments:
• Agua Caliente Band of Cahuilla Indians
• Augustine Band of Cahuilla Indians
• Cabazon Band of Mission Indians
• Cahuilla Band of Indians
• Campo Band of Diegueno Mission
Indians
• Ewiiaapaayp Band of Kumeyaay Indians
• La Posta Band of Diegueno Mission

Reservation
• Ramona Band of Cahuilla
• Santa Rosa Band of Cahuilla Indians
• Soboba Band of Luiseno Indians
• Torres -Martinez Desert Cahuilla Indians
• Twenty -Nine Palms Band of Mission

The City received responses from two tribes: the Morongo Band of Mission Indians and the Agua Caliente
Band of Cahuilla Indians (Appendix C: Cultural Resources). The Morongo Band stated that the project site
is not within their ancestral territory or traditional use area. The Agua Caliente Band indicated that, although
the project area is outside their reservation boundaries, it lies within their Traditional Use Area, and a
records search identified nearby surveys that confirmed the presence of cultural resources.

Code section 5024.1, the lead agency shall consider the significance of the resource to a
California Native American Tribe?
Less than Significant with Mitigation Incorporated: As discussed in Section 3.5, Cultural Resources, the
analysis relies on a search of the SLF conducted by the NAHC on March 8, 2024. The search included a
review of the CRHR as well as local registers yielding no specific site information, indicating a negative
result. However, it is essential to understand that the absence of such information in the SLF search does
not necessarily imply the absence of cultural resources within the Project area. Due to the negative result,
the tribes (referenced above) were contacted to satisfy the AB 52 consultation requirement under CEQA.
This analysis is also based on a review of cultural records accessed through the CHRIS EIC at the
University of California, Riverside. The examination of records occurred on January 22, 2024 involving a
comprehensive review of maps, documents, and reports relevant to the Project area. The findings revealed
that there have been 92 studies on cultural resources conducted within the approximately 410 acres of the
proposed Project area, with 56 documented cultural resource properties identified within its boundaries.
City of La Quinta Highway 111 Corridor Specific Plan 3-102
Environmental Analysis
Refer to Appendix C: Cultural Resources for the SLF search results and the Non -Confidential Cultural
Records Search report.
Potential future development may be required to prepare cultural resources reports to assess site -specific
impacts. As mentioned previously, a prior study identified two prehistoric resources (P-33-008692/CA-RIV-
006190, P-33-002936/CA-RIV-002936) in the Project area near Dune Palms Road and Highway 111
(Hallock et al., 2023). As such, if tribal cultural resources are disturbed or discovered during future
development, it could result in a significant impact. Therefore, implementing Mitigation Measures CR-1
through CR-9 during subsequent development phases would mandate further documentation of any tribal
cultural resources within the Project area, thereby minimizing impacts to a level deemed less than
significant.
Mitigation Measures
• CR-1: Workers Environmental Awareness Program
A Qualified Archaeologist who meets or exceeds the Secretary of Interior's Professional
Qualification Standards for archaeology (NPS, 1983) shall conduct Workers Environmental
Awareness Program (WEAP) training on archaeological sensitivity for all construction personnel
prior to the commencement of any ground -disturbing activities. Archaeological sensitivity training
shall include a description of the types of cultural material that may be encountered, cultural
sensitivity issues, the regulatory environment, and the proper protocol for treatment of the materials
in the event of a find. The WEAP training document shall include materials that convey the
information noted above, which shall be maintained in an area accessible to all construction
personnel so that it may be reviewed regularly by construction staff.
• CR-2: Pre -Excavation Agreement
Prior to the issuance of Grading Permits, the Applicant/Owner shall enter into a pre -excavation
agreement, otherwise known as a Tribal Cultural Resources Treatment and Tribal Monitoring
Agreement with consulting Tribal Monitor associated within the area. A copy of the agreement shall
be included in building and development plans and permit applications with the City. The purpose of
this agreement shall be to formalize protocols and procedures between the Applicant/Owner and the
consulting Tribal Monitor associated with the area for the protection and treatment of, including but
not limited to, Native American human remains, funerary objects, cultural and religious landscapes,
ceremonial items, and traditional gathering areas and tribal cultural resources located and/or
discovered through a monitoring program in conjunction with the construction of the proposed
project, including additional archaeological surveys and/or studies, excavations, geotechnical
investigations, grading, and all other ground disturbing activities. At the discretion of the consulting
Tribal Monitor, artifacts may be made available for 3D scanning/printing, with scanned/printed
materials to be curated at a local repository meeting the federal standards of 36CFR79.
• CR-3: Retention of Qualified Archaeologist and Tribal Monitor
Prior to the issuance of a Grading Permits, the Applicant/Owner or Grading Contractor shall provide
executed contracts or agreements with a Qualified Archaeologist and consulting Tribal Monitor, at
the Applicant/Owner or Grading Contractor's expense, to implement the monitoring program, as
described in the pre -excavation agreement.

• CR-4: Tribal Cultural Monitor Coordination During Ground Disturbing Activities
The Qualified Archaeologist and consulting Tribal Monitor shall attend all applicable pre -construction
meetings with the General Contractor and/or associated subcontractors to present the
archaeological monitoring program. The Qualified Archaeologist and consulting Tribal Monitor shall
be present on -site full-time during grubbing, grading, and/or other ground altering activities,
including the placement of imported fill materials or fill used from other areas of the Project site, to
identify any evidence of potential archaeological or tribal cultural resources. All fill materials shall be
absent of any and all tribal cultural resources.
• CR-5: Controlled Grade Procedure
The Qualified Archaeologist and consulting Native American Monitor shall attend all applicable pre -
construction meetings with the General Contractor and/or associated subcontractors to present the
archaeological monitoring program. The Qualified Archaeologist and consulting Tribal Monitor shall
be present on -site full-time during grubbing, grading, and/or other ground altering activities,
including the placement of imported fill materials or fill used from other areas of the Project site, to
identify any evidence of potential archaeological or tribal cultural resources. All fill materials shall be
absent of any and all tribal cultural resources.
• CR-6: Discovery of Tribal Cultural Resources
The Qualified Archaeologist and consulting Tribal Monitor can stop ground -disturbing activities if
undiscovered tribal cultural resources or artifacts are found. All work must cease in the vicinity of
any archaeological discovery until the Qualified Archaeologist and Tribal Monitor can assess the
context of the find, including its significance, potential eligibility for the California Register of
Historical Resources (CRHR), and whether the project would have a direct impact on the resource.
If buried cultural deposits are encountered, the Archaeologist and Tribal Monitor may request that
construction halt nearby and must notify a Qualified Archaeologist within 24 hours for investigation.
Work will be redirected away from these areas for assessment. Minor finds will be documented and
secured for later repatriation; if items cannot be securely stored on -site, they may be stored off -site.
Minor finds include archaeological materials that are isolated, lack context, and are unlikely to
indicate a larger or significant site. If the discovered resources are deemed potentially significant,
the involved Tribes will be notified for consultation on their respectful treatment. Avoidance of
significant resources is preferred, but if not feasible, a data recovery plan may be required. The
consulting Tribes will be consulted on this plan as well.
For resources under a data recovery plan, a proper sample will be collected using professional
methods, reflecting tribal values. The Tribal Monitor must be present during any resource collection
or cataloging. If the Qualified Archaeologist does not collect the resources, the Tribal Monitor may
do so. Ground -disturbing work will not resume until the resources are documented and/or protected.
• CR-7: Treatment of Tribal Cultural Resources
The landowner shall relinquish ownership of all cultural resources unearthed during all ground
disturbing activities, and from any previous archaeological studies or excavations on the Project site
to the affiliated consulting Tribe, as determined through the appropriate process, for respectful and
dignified treatment and disposition, including reburial at a protected location on -site, in accordance
with the Tribe's cultural and spiritual traditions. All cultural materials that are associated with burial

and/or funerary goods would be repatriated to the Most Likely Descendant as determined by the
NAHC per California Public Resources Code Section 5097.98. No tribal cultural resources shall be
subject to curation.
• CR-8: Tribal Cultural Monitoring Report
A monitoring report and/or evaluation report, if appropriate, which describes the results, analysis,
and conclusions of the archaeological monitoring program (e.g., data recovery plan) shall be
submitted by the Qualified Archaeologist, along with the consulting Tribal Monitor's notes and
comments, to the City of La Quinta Planning Division for approval.
• CR-9: Unanticipated Discovery of Human Remains
As specified by California Health and Safety Code Section 7050.5, if human remains are found on
the Project site during construction or during archaeological work, the person responsible for the
excavation, or his or her authorized representative, shall immediately notify the Riverside County
Coroner's Office by telephone. No further excavation or disturbance of the site or any nearby area
reasonably suspected to overlie adjacent remains shall occur until the Coroner Medical Examiner
has made the necessary findings as to origin and disposition pursuant to Public Resources Code
5097.98. If such a discovery occurs, a temporary construction exclusion zone shall be established
surrounding the area of the discovery so that the area would be protected, and consultation and
treatment could occur as prescribed by law. If suspected Native American remains are discovered,
the remains shall be kept in -situ, or in a secure location in close proximity to where they were found,
and the analysis of the remains shall only occur on -site in the presence of a Tribal Monitor. By law,
the Coroner Medical Examiner shall determine within two working days of being notified if the
remains are subject to his or her authority. If the Coroner Medical Examiner identifies the remains to
be of Native American ancestry, he or she shall contact the NAHC within 24 hours. The NAHC shall
make a determination as to the Most Likely Descendent. If human remains are discovered, notify the
consulting Tribe's Tribal Historic Preservation Officer.

As the City continues to grow, the provision of essential public and quasi -public services becomes
increasingly critical. This is especially true for areas like the Highway 111 Corridor, where utilities play a
pivotal role in supporting future development. Adequate utilities — such as water, sewer, electricity, natural
gas, and telecommunications — are fundamental for implementing the Specific Plan. Without these services,
the planned development and expansion could be significantly hindered or even unachievable. Ensuring
robust and reliable utility infrastructure is, therefore, essential for accommodating growth and achieving the
City's long-term vision for development.
The Specific Plan would create a mix of land uses guided by site -specific development standards (i.e.,
Highway 111 Development Code) to ensure alignment with the City's General Plan. It would also
encourage water conservation features, such as low -flow plumbing fixtures, drought -tolerant native
landscaping, and efficient irrigation systems. The City's General Plan recognizes the need for sufficient
water, sewer, and other utilities to support planned growth and anticipated population increases in the
coming years. The Water, Sewer and other Utilities Element as well as the Natural Resources: Water
Resources Element of the General Plan establishes goals, policies, and programs to ensure these services
are provided as the City grows (City of La Quinta, 2022). Relevant General Plan policies are outlined in
detail below in response to question b).
City of La Quinta Highway 111 Corridor Specific Plan 3-106
Environmental Analysis
Domestic Water
The City of La Quinta relies primarily on groundwater from the CV Groundwater Basin for its domestic water
supply. This groundwater is extracted through a network of wells managed by the CVWD, which also
oversees the City's irrigation and water distribution services.
In addition to groundwater, CVWD supplements the City's water needs with imported water, delivered via
regional canals. This imported water is stored or recharged into the aquifer through basins located in the
west end of the Valley, such as the Whitewater River northwest of Palm Springs, as well as through
facilities in Martinez Canyon and a dike in the southeastern section of the City.
CVWD operates and maintains an extensive water distribution system, primarily located beneath existing
streets in the public right-of-way. CVWD also manages water storage tanks throughout the area with
capacities ranging from 250,000 to 10 million gallons (City of La Quinta, 2022).
Under the California Water Code, CVWD is responsible for assessing both current and future water
supplies to ensure that adequate resources are available for the City's land uses. This includes the
preparation of an Urban Water Management Plan (UWMP) to address and plan for the City's ongoing and
future water needs.
Sanitary Sewer
CVWD also manages sanitary sewer collection and treatment for the City, with most areas served by sewer
systems, though some parts of the City still use septic systems. The City is served by two wastewater
treatment plants. Wastewater from the northern part of the City, north of Miles Avenue, is directed to Water
Reclamation Plant 7 on Madison Street and Avenue 38, which has a capacity of 5 million gallons per day
(mgd). Wastewater from areas south of Miles Avenue is treated at the Mid -Valley Water Reclamation Plant,
located southeast of the City, with a capacity of 9.5 mgd.
Water Reclamation Plant 7 currently produces 2.5 mgd of tertiary treated water for irrigation, with the
potential to expand to 7.5 mgd. The Mid -Valley plant does not yet provide tertiary treated water, but there
are plans to extend this system to other areas (City of La Quinta, 2022).
Electricity
Power in the City is supplied by the IID, a public utility serving various parts of Southern California. IID
delivers power through its own generation and contractual agreements, with electricity transmitted at 92 or
161 kilovolts to its substations and then reduced to 12 kilovolts for distribution (City of La Quinta, 2022).
Natural Gas
Natural gas is the main energy source in the City of La Quinta, supplied by Southern California Gas
Company (SoCalGas), the largest natural gas utility in the U.S. with extensive coverage across southern
California. Major gas supply lines run along Washington Street and Highway 111. However, natural gas
service is less extensive in the southern part of the City, especially south of Airport Boulevard and east of
Monroe Street (City of La Quinta, 2022; City of La Quinta, 2024c).
Solid Waste Management
Burrtec Waste and Recycling Services, LLC (Burrtec) manages solid waste disposal in La Quinta. Burrtec
collects waste and transport it to the Edom Hill Transfer Station in Cathedral City, where it is then sent to
regional landfills with sufficient long-term capacity: Lamb Canyon, Badlands, or El Sobrante. Burrtec also
oversees recycling for residential and commercial sectors, covering paper, plastic, glass, aluminum, and
City of La Quinta Highway 111 Corridor Specific Plan 3-107
Environmental Analysis
green waste. The City meets its requirement to recycle at least 50% of its waste. Additionally, Burrtec
handles special programs for household hazardous waste, construction and demolition materials, medical
sharps, and commercial recycling (City of La Quinta, 2022; City of La Quinta, 2024c).
Telecommunications
In the City, Verizon serves as the primary landline telephone provider, while Time Warner is the main cable
TV provider. The City has seen a range of communication options evolve due to advancements in
technology and changes in regulations. Residents and businesses now have access to various services,
including cellular, internet-based communication, fiber optic networks, and cable -based solutions. Several
telecommunications companies such as Spectrum, which offers cable TV, internet, and phone services,
AT&T, which provides internet, phone, and TV services, and Frontier Communications, which delivers
internet and phone services with varying availability, cater to these needs (City of La Quinta, 2022). As the
City continues to grow, it is anticipated that new technologies would further enhance communication and
data transfer capabilities for both its residents and businesses.
a) Require or result in the relocation or construction of new or expanded water, wastewater
treatment or storm water drainage, electrical power, natural gas, or telecommunications
facilities, the construction or relocation of which could cause significant environmental
effects?
Less Than Significant Impact: Under the Specific Plan, if the proposed buildout is economically feasible,
it is expected to lead to a substantial increase in the construction of new buildings and utilities as well as the
expansion of existing ones. This growth would entail the addition of significant square footage dedicated to
various purposes, including residential, retail, office spaces, and hotels. Consequently, there would be a
heightened demand for essential utilities and infrastructure to support these developments effectively.
To accommodate the increased requirements of such development, various utility facilities would need to
be constructed or expanded. These utilities may encompass water supply and distribution systems,
wastewater treatment plants, stormwater drainage systems, electrical power infrastructure, natural gas
distribution networks, and telecommunications facilities. Each of these systems plays a crucial role in
providing the necessary resources for the functioning of residential and commercial properties, ensuring
that businesses can thrive and residents have access to essential services.
To address the potential environmental impacts associated with this buildout, the Specific Plan emphasizes
the importance of adhering to the Water, Sewer, and Other Utilities Element within the City's General Plan.
This element outlines comprehensive guidelines and regulations regarding the development and
management of utility facilities based on current and future projected population growth within the City.
Additionally, the Natural Resources: Water Resources Element of the City's General Plan is another crucial
aspect considered in this context, which focuses on water resource management and conservation to meet
the needs of current and future development within the City. By adhering to these General Plan guidelines
and the goals outlined by this Specific Plan, developers and authorities can ensure that future construction
and expansion of utility facilities are conducted in sustainable manner. Additionally, future development in
the Specific Plan area will utilize this impact analysis for environmental assessments, offering a
programmatic overview that will likely be tiered from this document to evaluate impacts on new or expanded
utilities within the area. As such, impacts on utility systems as a result of this Specific Plan implementation
are anticipated to be less than significant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-108
Environmental Analysis
b) Have sufficient water supplies available to serve the project and reasonably foreseeable
future development during normal, dry and multiple dry years?
Less Than Significant Impact with Mitigation Incorporated: As the new developments under the
Specific Plan commence, they would require a reliable and adequate water supply to meet the needs of
their occupants and operations. This includes not only the water required for residential purposes but also
for commercial activities, hotel services, landscaping, and other essential functions within these structures.
To accommodate the heightened demand, proper planning and management of water resources become
crucial. This may involve assessing the existing water infrastructure and identifying potential upgrades or
expansions to ensure sufficient supply to meet the new demand. It might also require exploring sustainable
water management practices, such as rainwater harvesting, water recycling, or implementing water -efficient
technologies and fixtures, to minimize excessive water consumption.
CVWD is responsible under the California Water Code for evaluating current and future water supplies to
meet district needs. The UWMP is regularly updated to ensure it remains current. Due to ongoing growth
and increased demand, CVWD has overdrafted from the Lower Thermal subarea since the 1980s. To
address this, CVWD is expanding recharge facilities and emphasizing water conservation, crucial for
managing overdraft as the city continues to grow. Additionally, all new residential and nonresidential
buildings in California must follow the CalGreen Codes. These codes mandate a 20% reduction in indoor
water use through efficient fixtures and require irrigation systems that prevent waste by monitoring soil and
weather conditions. Please refer to California Department of General Services for the most recent CalGreen
Codes (DGS, 2024). Over the next 25 years, the codes would become progressively stricter to further
conserve water (City of La Quinta, 2022).
All new development projects would necessitate domestic water for indoor use and landscaping irrigation,
which would put additional strain on the already limited water resources. To address this, the City has
already taken steps to implement water conservation initiatives and would need to persistently and further
expand these efforts to safeguard its water resources (City of La Quinta, 2022). By adhering to the goals
and objectives outlined in the City's General Plan as well as this Specific Plan, future development can
reduce potential impacts on water resources to a less than significant level with the incorporation of
proposed mitigation measure HWQ-2.
Relevant Policies from the General Plan:
• Policy WR-1.1: Support the Coachella Valley Water District in its efforts to supply adequate
domestic water to residents and businesses.
• Policy WR-1.2: Support the Coachella Valley Water District in its efforts to recharge the aquifer.
• Policy UTL-1.1: The City should coordinate with the Coachella Valley Water District to assure that
sufficient water supplies are available to sustain current and future development.
• Policy UTL-1.2: The City should encourage the conservation of water.
— Program UTL-1.2a: Develop programs, both in conjunction with the Coachella Valley Water
District and independently, to allow and encourage the retrofitting of existing water -intensive
appliances and irrigation systems in existing development
— Program UTL-1.2b: City and private sector development projects shall implement water
efficient landscaping plans which meet or exceed current water efficiency standards.
City of La Quinta Highway 111 Corridor Specific Plan 3-109
Environmental Analysis
Policy UTL-1.3: New development shall reduce its projected water consumption rates over
"business -as -usual" consumption rates.
Policy UTL-1.4: Review and amend Development Standards to require that all new development
demonstrate a reduction of domestic water consumption equivalent to, or exceeding, the CalGreen
Tier One standards in effect at the time of development.
Mitigation Measures: HWQ-2.
c) Result in a determination by the wastewater treatment provider which serves or may serve
the project that it has adequate capacity to serve the project's projected demand in addition
to the provider's existing commitments?
Less Than Significant Impact: Future development scenarios outlined in the Specific Plan would likely
increase the need and demand for wastewater treatment. Future development would need to adhere to
Building Code requirements that mandate the incorporation of water -efficient fixtures in new homes or
businesses and in those undergoing major remodeling. These regulations also apply to water features, and
fountains, as they can be a significant source of water loss, especially considering the evaporation that
occurs in the City's desert environment.
The City also mandates that all development projects must manage and regulate rainwater runoff that flows
through a developed site, typically achieved by constructing retention basins. These basins are often
landscaped and designed to enable stormwater to soak into the ground, promoting natural percolation (City
of La Quinta, 2022). Therefore, future development under the Specific Plan would be required to adhere to
these requirements.
The Specific Plan offers conceptual guidance for future development. Developers can reference this
Specific Plan and if needed, create a tiered CEQA document to further assess the need for expanding
existing wastewater treatment facilities or adding individual septic systems to accommodate growth in the
area. As such, impacts are expected to be less than significant.
Relevant Policies from the General Plan:
Policy WR-1.3: Support the Coachella Valley Water District in its efforts to expand tertiary treated
(i.e. reclaimed) water distribution.
Policy WR-1.4: Protect stormwater from pollution and encourage its use to recharge the aquifer.
Policy WR-1.6: Encourage the use of permeable pavements in residential and commercial
development projects.
Mitigation Measures: No mitigation measures required.
d, e) Generate solid waste in excess of State or local standards, or in excess of the capacity of
local infrastructure, or otherwise impair the attainment of solid waste reduction goals?
Comply with federal, state, and local management and reduction statutes and regulations
related to solid waste?
Less than Significant Impact: As development continues to grow under the Specific Plan, there would be
a corresponding rise in the volume of solid waste generated. Burrtec provides waste disposal services
under a franchise agreement with the City, collecting solid waste and transporting it to the Edom Hill
Transfer Station in Cathedral City. From there, waste is taken to one of three regional landfills — Lamb

Environmental Analysis
Canyon, Badlands, or El Sobrante — which have sufficient capacity for long-term needs (City of La Quinta,
2022). Thus, impacts are expected to be less than significant.
All future developments would be required to comply with the diversion requirements, Municipal Code
requirements and the City's General Plan policies. These requirements would maximize waste stream
diversions and help reduce solid waste disposal impacts related to compliance with federal, state, and local
regulations related to the solid waste generated from future development in accordance with the Specific
Plan.
The City is committed to recycling at least 50% of its solid waste, a target it currently meets. Burrtec
manages specialized programs for household hazardous waste, construction materials, medical "sharps,"
and commercial recycling (City of La Quinta, 2022). Future site -specific development would be required to
abide by relevant laws and regulations governing solid waste disposal treatment. As such, impacts
associated with solid waste are expected to be less than significant.
Mitigation Measures: No mitigation measures required.
Utilities and Service Systems Mitigation Measures
• HWQ-2: Water Conservation Measures
Future development in the Highway 111 Corridor must integrate water -saving appliances and
fixtures, such as low -flush toilets, low -flow showerheads, and faucets, in compliance with Section
17921.3 of the Health and Safety Code, Title 20 of the California Administrative Code Section
1601(b), and relevant sections of Title 24 of the California State Code. Additionally, the City would
enforce its Water Efficient Landscape ordinance, requiring development projects within the Specific
Plan area to adopt water -efficient landscaping plans that meet or exceed current criteria. These
measures are aimed at conserving water resources while addressing the needs of residents and
businesses.

3.20 Wildfire
Would the project:
a) Substantially impair an adopted emergency
response plan or emergency evacuation plan?
b) Due to slope, prevailing winds, and other factors,
exacerbate wildfire risks, and thereby expose
project occupants to pollutant concentrations from
a wildfire or the uncontrolled spread of a wildfire?
c) Require the installation or maintenance of
associated infrastructure (such as roads, fuel
breaks, emergency water sources, power lines or
other utilities) that may exacerbate fire risk or that
may result in temporary or ongoing impacts to the
environment?
d) Expose people or structures to significant risks,
including downslope or downstream flooding or
landslides as a result of runoff, post -fire slop
instability, or drainage changes?
The Project area is located in the City's urban core and is not in proximity to a Fire Hazard Severity Zone
(CAL FIRE, 2023). The nearest moderate Fire Hazard Severity Zone is approximately 5 miles southwest of
the Project area.
a) Substantially impair an adopted emergency response plan or emergency evacuation plan?
Less Than Significant Impact: The LHMP for the City underscores a commitment to construction
regulations that prioritize safety. This involves adopting and rigorously enforcing existing building codes,
with provisions for promptly amending them when local deficiencies are identified, all aimed at ensuring the
community's safety. All new construction projects are required to adhere to the City's Building or Fire Codes
to ensure all future development meets the prescribed minimum standards for fire safety. These standards
are determined by factors such as the building type, design, intended occupancy, and usage. To further
enhance fire safety measures, the City has entered into an agreement with the RCFD for comprehensive
fire services. These services encompass not only firefighting capabilities but also extend to community
outreach initiatives aimed at promoting fire safety awareness and prevention strategies (City of La Quinta,
2022). Future developments would be required to implement the LHMP and General Plan policies regarding
emergency response and evacuation; therefore, impacts are anticipated to be less than significant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-112
Environmental Analysis
b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby
expose project occupants to pollutant concentrations from a wildfire or the uncontrolled
spread of a wildfire?
Less Than Significant Impact: The proposed area under the Specific Plan is not considered a Fire Hazard
Severity Zone (CAL FIRE, 2023). While the City itself may not be situated within a wilderness expanse, the
potential for wildland fires within its vicinity remains substantial due to the juxtaposition of wildland and
urban zones. The extensive development in the City and surrounding environment has resulted in what is
known as the Wildland-Urban Interface (WUI), a terrain that presents a heightened susceptibility to wildland
fires. This vulnerability is exacerbated by the prevalence of extended drought periods and the prevalent
aridity in these locales, rendering them particularly prone to wildfires (City of La Quinta, 2022).
Furthermore, the influence of Santa Ana winds provides an additional fire safety concern. These winds
possess the capability to swiftly propagate wildfires across the community. The threat of wildland fire
occurrences extends far beyond isolated areas; it blankets approximately 90% of Riverside County,
reaching into the City. This includes open spaces, parklands, and agricultural regions. Therefore, the issue
of wildland fire hazards is a complex concern with wide -reaching implications for the entire region. This
underscores the need for comprehensive attention and strategic actions to effectively manage and mitigate
the associated risks. (City of La Quinta, 2022).
Development under the Specific Plan would include the development of Medium -Hazard Occupancies as
defined by the National Fire Protection Association (NFPA), however, by adhering to and enforcing
established mandates, such as the California Building Code, California Fire Code, La Quinta Municipal
Codes, CEQA Statutes and Guidelines, and other pertinent fire safety regulations, the mitigation of fire -
related risks can be effectively managed (La Quinta, 2022). Therefore, less than significant impacts are
anticipated.
Mitigation Measures: No mitigation measures required.
c) Require the installation or maintenance of associated infrastructure (such as roads, fuel
breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk
or that may result in temporary or ongoing impacts to the environment?
Less Than Significant Impact: The Specific Plan serves as a policy -level document designed to guide
future development along the Highway 111 Corridor. Consequently, any future projects within the Specific
Plan area will likely reference and tier off of this CEQA document to further assess infrastructure constraints
related to fire risks. Additional discussion of water sources and utilities can be found in Section 3.19 of this
IS/MND. Future projects may necessitate additional infrastructure to adequately support new development.
Any future development would require further CEQA review to ensure that proposed improvements do not
entail infrastructure that could worsen wildfire risks. The adoption and implementation of developments
under the Specific Plan would not significantly exacerbate wildfire risks above existing conditions. As such,
impacts are considered to be less than significant.
Mitigation Measures: No mitigation measures required.
City of La Quinta Highway 111 Corridor Specific Plan 3-113
Environmental Analysis
d) Expose people or structures to significant risks, including downslope or downstream
flooding or landslides as a result of runoff, post -fire slope instability, or drainage changes?
Less than Significant Impact: As described previously, the Specific Plan does not include any site -
specific designs for development and is only intended to serve as a guidance document for the City in
implementing future development along the Highway 111 Corridor. The Specific Plan area occupies a
predominantly flat terrain and is generally not susceptible to downslope flooding or landslides due to its
topographic features. As such, future development along the Project area is not anticipated to expose
people or structures to significant risks, including downslope or downstream flooding or landslides, as a
result of runoff, post -fire slope instability, or drainage changes. Portions of the Project area that are
adjacent to the Whitewater River Wash are located within Special Flood Hazard Areas; however, these
areas have between 0.2% and 1 % annual chance of flooding with average depths of less than one foot or
with drainage areas of less than one square mile. There are no FEMA-regulated floodways identified within
the Project area (FEMA, 2024). Impacts are deemed less than significant.
Mitigation Measures: No mitigation measures required.

plant or animal or eliminate important examples of the major periods of California history or
prehistory?
Less Than Significant Impact with Mitigation Incorporated: As outlined in Section 3.4, Biological
Resources, the proposed Specific Plan is expected to have no direct impact on biological resources. Future
improvements under the Specific Plan would comply with relevant federal, state, and local regulations. The
implementation of Mitigation Measure 131O-1 would ensure construction personnel receive environmental
awareness training to mitigate potential impacts on special -status species and their habitats. Similarly, 1310-
2 would establish best practices to minimize impacts on natural habitats and wildlife. Furthermore,
implementation of 131O-3 would guide the protection of special -status and migratory birds during
construction, and 131O4 would provide specific guidance on focused burrowing owl surveys. Mitigation
Measures 131O-5 and 131O-6 offer strategies for reducing nonessential lighting to safeguard wildlife at the
Project site, as well as guidance on securing approval from CDFW under Section 1602 of the Fish and
Game Code for any impacts to a stream or riverbed. Lastly, 131O-7 would emphasize adherence to
conservation measures specified in the CVMSHCP. Together, these measures would effectively reduce
impacts to species and their habitats to less than significant levels.
Similarly, as detailed in Section 3.5, Cultural Resources, the proposed Specific Plan is not expected to
impact significant periods of California history or cultural and historic resources. Future developments
City of La Quinta Highway 111 Corridor Specific Plan 3-115
Environmental Analysis
outlined in the Specific Plan would be subject to mitigation measures CR-1 through CR-9, ensuring that any
unearthed resources are properly managed. With the implementation of these cultural mitigation measures,
impacts to cultural and historic resources are anticipated to be reduced to less than significant levels.
Mitigation Measures: BIO-1 through BIO-7, and CR-1 through CR-9.
b) Does the project have impacts that are individually limited, but cumulatively considerable?
("Cumulatively considerable" means that the incremental effects of a project are
considerable when viewed in connection with the effects of past projects, the effects of other
current projects, and the effects of probable future projects)?
Less Than Significant Impact with Mitigation Incorporated: Cumulative impacts are defined as "two or
more individual effects which, when considered together, are considerable or which compound or increase
other environmental impacts" (CEQA Guidelines Section 15355). Cumulative impacts can result from
individually minor, but collectively significant actions taking place over a period of time.
This Specific Plan aligns with the City's General Plan policies and goals as well as City Codes. Evidence in
this Finding of Consistency shows no new significant environmental effects beyond those identified in the
City's General Plan. The General Plan envisions the Highway 111 Corridor evolving into a prime mixed -use
area, reflecting its goals for innovative development. This Specific Plan would guide the transformation of
Highway 111 to improve quality of life for residents, employees, and visitors, envisioning it as a standout
destination offering a variety of memorable experiences.
Future development guided by this Specific Plan may have cumulative impacts on air quality, natural
resources, hazards, cultural/tribal resources, public services, and population and housing. While future
development along the Highway 111 Corridor would lead to some environmental changes, potential impacts
associated with these environmental disciplines are expected to be minor or mitigated to a less significant
level through recommended measures in the Specific Plan. This approach would also ensure that any
contribution to cumulative impacts remains minimal.

The impacts associated with the proposed Specific Plan would not add appreciably to any existing or
foreseeable future significant cumulative environmental impact. Incremental impacts, if any, would be
negligible. All potential direct and indirect impacts of the Project can be avoided or minimized to a level that
is considered insignificant, as summarized in Appendix A: Mitigation Monitoring and Reporting Program
(MMRP). Consequently, the proposed Project's cumulative impacts are not considered significant, as any
applicable impacts it may contribute to would be mitigated to a less than significant level.
Mitigation Measures: BIO-1 through BIO-7, CR-1 through CR-9, AIR-1, GEO-1, HAZ-1, HAZ-2, HWQ-1,
HWQ-2, and NOI-1.
c) Does the project have environmental effects which would cause substantial adverse effects
on human beings, either directly or indirectly?
Less Than Significant Impact with Mitigation Incorporated: Future development contemplated by the
proposed Specific Plan could potentially lead to environmental impacts related to air quality, geology and
soils, hazardous materials, water quality, noise, and utilities. While the Specific Plan itself does not involve
construction, it serves as a guide for future development. The IS/MND for the Specific Plan ensures
compliance with regulations to mitigate these potential impacts. Mitigation Measures AIR-1, GEO-1, HAZA,
HAZ-2, HWQ-1, HWQ-2, and NOI-1 would help lessen environmental impacts by minimizing pollutants and
conserving natural resources, thereby reducing direct health risks and indirect effects on important
ecosystems that support human well-being. With these measures in place, the Specific Plan is expected to
avoid significant adverse effects on human health and the environment.
Mitigation Measures: AIR-1, GEO-1, HAZ-1, HAZ-2, HWQ-1, HWQ-2, and NOI-1.
City of La Quinta Highway 111 Corridor Specific Plan 3-117
Environmental Analysis
Mandatory Findings of Significance Mitigation Measures:
• BIO-1: Assessment of Biological Resources and Worker Environmental Awareness
Training
Prior to Project construction activities for all projects covered in this IS/MND, a complete and recent
inventory of rare, threatened, endangered, and other sensitive species located within the Project
footprint and within offsite areas with the potential to be affected, including California Species of
Special Concern and California Fully Protected Species (Fish and Game Code § 3511), will be
completed. Species to be addressed should include all those which meet the CEQA definition
(CEQA Guidelines § 15380). The inventory should address seasonal variations in use of the Project
area and should not be limited to resident species. Focused species -specific surveys, completed by
a qualified biologist and conducted at the appropriate time of year and time of day when the
sensitive species are active or otherwise identifiable are required. Acceptable species -specific
survey procedures should be developed in consultation with CDFW and the U.S. Fish and Wildlife
Service, where necessary. Note that CDFW generally considers biological field assessments for
wildlife to be valid for a one-year period, and assessments for rare plants may be considered valid
for a period of up to three years. Some aspects of the proposed Project may warrant periodic
updated surveys for certain sensitive taxa, particularly if the Project is proposed to occur over a
protracted time frame, or in phases, or if surveys are completed during periods of drought.
An environmental training program should be developed and presented by a qualified biologist to all
crew members prior to the beginning of all Project construction in natural areas planned for
development. The training should describe special -status plant and wildlife species and sensitive
habitats that could occur within the Project area, protection afforded to these species and habitats,
and avoidance and minimization measures required to avoid and/or minimize impacts from the
project.
All new construction personnel should receive this training before beginning work on this Project. A
copy of the training and training materials should be provided to construction crews for review and
approval at least 30 days prior to the start of construction. As needed, in -field training should be
provided to new on -site construction personnel by the qualified biologist or a qualified individual who
should be identified by the qualified biologist, or initial training should be recorded and replayed for
new personnel.
• BIO-2: General Measures for Plants and Wildlife
When working in the natural habitat areas, the number of access routes, number and size of staging
areas, and the total area of the activity should be limited to the minimum necessary to achieve the
project goal. Routes and boundaries outside of normal access roads should be clearly delineated
through fencing or flagging.
Food, trash, and other solid wastes should be disposed of in Common Raven proof/wildlife proof,
covered refuse containers and regularly removed from the various structures and facilities on a daily
basis to avoid offsite dispersal of waste and to avoid attracting wildlife onto the Project site.
Following covered activity work, all trash and debris should be removed from the work area.
Construction work should avoid direct destruction of burrows through chaining (dragging a heavy
chain over an area to remove shrubs), disking, cultivation, and urban, industrial, or agricultural
development.
City of La Quinta Highway 111 Corridor Specific Plan 3-118
Environmental Analysis
Project -related excavations greater than 6 inches deep should be secured to prevent wildlife entry
and entrapment. Holes and trenches should be back -filled, securely covered, or fenced. Excavations
that cannot be fully secured should incorporate appropriate wildlife ramp(s) at a slope of no more
than a 3:1 ratio (horizontal: vertical, equivalent to a 33.3 percent or 18.4-degree slope), or other
means to allow trapped animals to escape.
Personnel on site should be required to check under their vehicles for sensitive species prior to
moving them and should exercise caution while driving on the Project site.
Before moving, burying, or capping, inspect for wildlife in any construction pipes, culverts, or similar
structures that are stored on the site for one or more nights. Alternatively, cap structures before
storing on the work site.
• BI0-3: Special Status and Migratory Birds
Construction should be conducted, if possible, during the fall and/or winter months and outside of
the avian nesting season (generally February 1 — August 31) to avoid any direct and or indirect
effects to protected nesting birds. Pre -construction surveys shall focus on both direct and indirect
evidence of nesting, including nest locations and nesting behavior. The qualified avian biologist will
make every effort to avoid potential nest predation as a result of survey and monitoring efforts. If
active nests are found during the pre -construction nesting bird surveys, a qualified biologist shall
establish an appropriate nest buffer to be marked on the ground. Nest buffers are species specific
and shall be at least 100 feet for passerines and 300 feet for raptors. A smaller or larger buffer may
be determined by the qualified biologist familiar with the nesting phenology of the nesting species
and based on nest and buffer monitoring results. Construction activities may not occur inside the
established buffers, which shall remain on -site until a qualified biologist determines the young have
fledged or the nest is no longer active. Active nests and adequacy of the established buffer distance
shall be monitored at least once a week or as needed by the qualified biologist until the qualified
biologist has determined the young have fledged or the Project has been completed. The qualified
biologist has the authority to stop work if nesting pairs exhibit signs of disturbance.
• BIO-4: Burrowing Owl Habitat Assessment and Focused Pre -Construction Surveys
No less than 60 days prior to the start of Project -related activities for all projects covered in the
MND, a burrowing owl habitat assessment shall be conducted by a qualified biologist according to
the specifications of the Staff Report on Burrowing Owl Mitigation (Department of Fish and Game,
March 2012 or most recent version) for all projects covered under the MND.
If the habitat assessment demonstrates suitable burrowing owl habitat, then focused burrowing owl
surveys shall be conducted by a qualified biologist in accordance with the Staff Report on Burrowing
Owl Mitigation (2012 or most recent version) prior to vegetation removal or ground -disturbing
activities. If burrowing owls are detected during the focused surveys, the qualified biologist and
Project proponent shall begin coordination with CDFW and USFWS immediately, and shall prepare
a Burrowing Owl Avoidance and Monitoring Plan that shall be submitted to CDFW for review and
approval prior to commencing Project activities. The Burrowing Owl Plan shall describe proposed
avoidance and monitoring actions, including measures necessary to avoid take of burrowing owl
individuals, nests, and eggs. The Burrowing Owl Plan shall include the number and location of
occupied burrow sites (occupied site means at least one burrowing owl or its sign has been
observed within the last three years; may be indicated by owl sign including feathers, pellets, prey
remains, eggshell fragments, or excrement at or near a burrow entrance or perch site), acres of
burrowing owl habitat that will be impacted, details of site monitoring, and details on proposed
City of La Quinta Highway 111 Corridor Specific Plan 3-119
Environmental Analysis
buffers and other avoidance measures. If impacts to occupied burrowing owl habitat or burrow(s) or
burrowing owl individuals, nests, or eggs cannot be avoided, appropriate California Endangered
Species Act (CESA) authorization (i.e., Incidental Take Permit under Fish and Game Code section
2081) should be obtained from CDFW prior to commencement of Project activities.
Preconstruction burrowing owl surveys shall be conducted no less than 14 days prior to the start of
Project -related activities and within 24 hours prior to ground disturbance, in accordance with the
Staff Report on Burrowing Owl Mitigation (2012 or most recent version). Preconstruction surveys
should be repeated when there is a pause in construction of more than 30 days. Preconstruction
surveys should be performed by a qualified biologist following the recommendations and guidelines
provided in the Staff Report on Burrowing Owl Mitigation. If the preconstruction surveys confirm
occupied burrowing owl habitat, Project activities shall be immediately halted. The qualified biologist
shall coordinate with CDFW and prepare a Burrowing Owl Avoidance and Monitoring Plan that shall
be submitted to CDFW and USFWS for review and approval prior to commencing Project activities.
• 113I0-5: Artificial Light Impacts
Throughout construction and the lifetime operation of all projects covered in the IS/MND the City
and Project proponents shall eliminate all nonessential lighting throughout the Project area and
avoid or limit the use of artificial light at night during the hours of dawn and dusk when many wildlife
species are most active. The City and Project proponent shall ensure that all lighting for the Project
is fully shielded, cast downward and directed away from surrounding open -space and agricultural
areas, reduced in intensity to the greatest extent possible, and does not result in lighting trespass
including glare into surrounding areas or upward into the night sky (see the International Dark -Sky
Association standards at http://darksky.org/). The City and Project proponent shall ensure use of
LED lighting, proper disposal of hazardous waste, and recycling of lighting that contains toxic
compounds with a qualified recycler.
• 113I0-6: CDFW Lake and Streambed Alteration (LSA) Program
Prior to construction and issuance of any grading permit, the Project Sponsor shall obtain written
correspondence from CDFW stating that notification under Section 1602 of the Fish and Game
Code is not required for the Project, or the Project Sponsor should obtain a CDFW-executed Lake
and Streambed Alteration Agreement, authorizing impacts to Fish and Game Code Section 1602
resources associated with the Project.
• BI0-7: Project Adherence to the CVMSHCP
All Conservation Measures that are applicable within Section 4.4 (Required Avoidance,
Minimization, and Mitigation Measures) and Section 9 (Species Accounts and Conservation
Measures) of the CVMSHCP should be implemented by the Project to minimize impacts to plant and
wildlife species within the HCP's jurisdiction (CVMSHCP, 2016).
The Project is outside of a designated Conservation Area, and a Joint Review Project is not
required. However, the LDMF to the CVCC is required for development projects. Submission of the
LDMF to the CVCC is recommended before building or grading permits are submitted.
Prior to construction and issuance of any grading permit for all projects covered in the IS/MND, the
City shall ensure compliance with the CVMSHCP and its associated Implementing Agreement and
shall ensure the collection of payment of the CVMSHCP Local Development Mitigation Fee and
transfer of fees, at least quarterly and prior to impacts to Covered Species and their Habitats, to the
Coachella Valley Conservation Commission.
City of La Quinta Highway 111 Corridor Specific Plan 3-120
Environmental Analysis
Prior to vegetation removal or ground -disturbing activities, for all project areas covered in the
IS/MND that contain suitable habitat for sand -dependent Covered Species, the City will collaborate
with the Coachella Valley Conservation Commission to plan and implement a salvage of sand -
dependent Covered Species within the Project site.
• CR-1: Workers Environmental Awareness Program
A Qualified Archaeologist who meets or exceeds the Secretary of Interior's Professional
Qualification Standards for archaeology (NPS, 1983) shall conduct Workers Environmental
Awareness Program (WEAP) training on archaeological sensitivity for all construction personnel
prior to the commencement of any ground -disturbing activities. Archaeological sensitivity training
shall include a description of the types of cultural material that may be encountered, cultural
sensitivity issues, the regulatory environment, and the proper protocol for treatment of the materials
in the event of a find. The WEAP training document shall include materials that convey the
information noted above, which shall be maintained in an area accessible to all construction
personnel so that it may be reviewed regularly by construction staff.
• CR-2: Pre -Excavation Agreement
Prior to the issuance of Grading Permits, the Applicant/Owner shall enter into a pre -excavation
agreement, otherwise known as a Tribal Cultural Resources Treatment and Tribal Monitoring
Agreement with the consulting Tribal Monitor associated within the area. A copy of the agreement
shall be included in building and development plans and permit applications with the City. The
purpose of this agreement shall be to formalize protocols and procedures between the
Applicant/Owner and the consulting Tribal Monitor associated with the area for the protection and
treatment of, including but not limited to, Native American human remains, funerary objects, cultural
and religious landscapes, ceremonial items, and traditional gathering areas and tribal cultural
resources located and/or discovered through a monitoring program in conjunction with the
construction of the proposed project, including additional archaeological surveys and/or studies,
excavations, geotechnical investigations, grading, and all other ground disturbing activities. At the
discretion of the consulting Tribal Monitor, artifacts may be made available for 3D scanning/printing,
with scanned/printed materials to be curated at a local repository meeting the federal standards of
36CFR79.
• CR-3: Retention of Qualified Archaeologist and Tribal Monitor
Prior to the issuance of a Grading Permits, the Applicant/Owner or Grading Contractor shall provide
a written and signed letter to the City of La Quinta Planning Division stating that a Qualified
Archaeologist and consulting Tribal Monitor have been retained at the Applicant/Owner or Grading
Contractor's expense to implement the monitoring program, as described in the pre -excavation
agreement.
• CR-4: Tribal Cultural Monitor Coordination During Ground Disturbing Activities
The Qualified Archaeologist and consulting Tribal Monitor shall attend all applicable pre -construction
meetings with the General Contractor and/or associated subcontractors to present the
archaeological monitoring program. The Qualified Archaeologist and consulting Tribal Monitor shall
be present on -site full-time during grubbing, grading, and/or other ground altering activities,
including the placement of imported fill materials or fill used from other areas of the Project site, to
City of La Quinta Highway 111 Corridor Specific Plan 3-121
Environmental Analysis
identify any evidence of potential archaeological or tribal cultural resources. All fill materials shall be
absent of any and all tribal cultural resources.
• CR-5: Controlled Grade Procedure
To detect important archaeological artifacts and cultural resources during monitoring, a "Controlled
Grade Procedure" must be created by a Qualified Archaeologist. This will be done in consultation
with the consulting Tribal Monitor, relevant consulting Tribes, and the Applicant/Owner, and needs
approval from City representatives. The procedure will set guidelines for machinery work in sensitive
areas identified during cultural resource monitoring. It will cover aspects like operating speed,
removal increments, weight, and equipment features. A copy of this procedure must be included in
the Grading Plan submissions for Grading Permits.
• CR-6: Discovery of Tribal Cultural Resources
The Qualified Archaeologist and consulting Tribal Monitor can stop ground -disturbing activities
undiscovered tribal cultural resources or artifacts are found. All work must cease in the vicinity of
any archaeological discovery until the Qualified Archaeologist and Tribal Monitor can assess the
context of the find, including its significance, potential eligibility for the California Register of
Historical Resources (CRHR), and whether the project would have a direct impact on the resource.
If buried cultural deposits are encountered, the Archaeologist and Tribal Monitor may request that
construction halt nearby and must notify a Qualified Archaeologist within 24 hours for investigation.
Work will be redirected away from these areas for assessment. Minor finds will be documented and
secured for later repatriation; if items cannot be securely stored on -site, they may be stored off -site.
Minor finds include archaeological materials that are isolated, lack context, and are unlikely to
indicate a larger or significant site. If the discovered resources are deemed potentially significant,
the involved consulting Tribes will be notified for consultation on their respectful treatment.
Avoidance of significant resources is preferred, but if not feasible, a data recovery plan may be
required. The consulting Tribes will be consulted on this plan as well.
For resources under a data recovery plan, a proper sample will be collected using professional
methods, reflecting tribal values. The Tribal Monitor must be present during any resource collection
or cataloging. If the Qualified Archaeologist does not collect the resources, the Tribal Monitor may
do so. Ground -disturbing work will not resume until the resources are documented and/or protected.
• CR-7: Treatment of Tribal Cultural Resources
The landowner shall relinquish ownership of all cultural resources unearthed during all ground
disturbing activities, and from any previous archaeological studies or excavations on the Project site
to the affiliated consulting Tribe, as determined through the appropriate process, for respectful and
dignified treatment and disposition, including reburial at a protected location on -site, in accordance
with the Tribe's cultural and spiritual traditions. All cultural materials that are associated with burial
and/or funerary goods would be repatriated to the Most Likely Descendant as determined by the
NAHC per California Public Resources Code Section 5097.98. No tribal cultural resources shall be
subject to curation.
• CR-8: Tribal Cultural Monitoring Report
A monitoring report and/or evaluation report, if appropriate, which describes the results, analysis,
and conclusions of the archaeological monitoring program (e.g., data recovery plan) shall be
City of La Quinta Highway 111 Corridor Specific Plan 3-122
Environmental Analysis
submitted by the Qualified Archaeologist, along with the consulting Tribal Monitor's notes and
comments, to the City of La Quinta Planning Division for approval.
• CR-9: Unanticipated Discovery of Human Remains
As specified by California Health and Safety Code Section 7050.5, if human remains are found on
the Project site during construction or during archaeological work, the person responsible for the
excavation, or his or her authorized representative, shall immediately notify the Riverside County
Coroner's Office by telephone. No further excavation or disturbance of the site or any nearby area
reasonably suspected to overlie adjacent remains shall occur until the Coroner Medical Examiner
has made the necessary findings as to origin and disposition pursuant to Public Resources Code
5097.98. If such a discovery occurs, a temporary construction exclusion zone shall be established
surrounding the area of the discovery so that the area would be protected, and consultation and
treatment could occur as prescribed by law. If suspected Native American remains are discovered,
the remains shall be kept in -situ, or in a secure location in close proximity to where they were found,
and the analysis of the remains shall only occur on -site in the presence of a consulting Tribal
Monitor. By law, the Coroner Medical Examiner shall determine within two working days of being
notified if the remains are subject to his or her authority. If the Coroner Medical Examiner identifies
the remains to be of Native American ancestry, he or she shall contact the NAHC within 24 hours.
The NAHC shall make a determination as to the Most Likely Descendent. If human remains are
discovered, notify the consulting Tribe's Tribal Historic Preservation Officer.
• AIR-1: Localized Significance Assessment
Prior to the issuance required discretionary permits, new development projects in the Specific Plan
area, if subject to CEQA compliance, must demonstrate that the proposed development would either
not exceed applicable the SCAQMD's LST lookup tables or not exceed the respective ambient air
quality thresholds for CO, NOx, and PM10 and PM2.5.
• GEO-1: Protect Paleontological Resources during Construction Activities
Prior to ground disturbing activities, all field personnel will receive training on paleontological
resources, including potential fossils that may be discovered and response steps, while a qualified
paleontologist will prepare a Paleontological Resources Monitoring and Mitigation Plan (PRMMP).
If fossils (like bones, teeth, or well-preserved plants) are found during construction, the City will stop
work within 50 feet and notify a paleontologist to document and assess the find. The paleontologist
may allow work to continue or recommend salvaging the fossils if necessary and will suggest
appropriate treatment methods. Collected fossils will be sent to an accredited institution for curation
and preservation.
All earth -moving operations deeper than two feet must have a qualified paleontological monitor.
Continuous monitoring is needed if fossil -rich lakebed sediments are found. The monitor can stop
work to identify and salvage fossils and may halt equipment for large specimens. A monitoring plan
must be submitted to the City before any permits are issued or soil is disturbed. Grading and
excavation must comply with La Quinta Code and regulations.
After ground disturbing activities and any necessary fossil curation, the project paleontologist will
prepare a final report detailing the results of the PRMMP.
City of La Quinta Highway 111 Corridor Specific Plan 3-123
Environmental Analysis
• HAZ-1: Hazardous Materials Handling and Planning
New development projects in the Specific Plan area must comply with local, state, and federal
regulations by submitting development plans and permits to the City for review. Projects intending to
use or store hazardous materials must prepare a Spill Prevention Countermeasure Contingency
Plan (SPCC) outlining spill containment protocols, along with maintaining an onsite SPCC spill kit.
Additionally, developments proposing storage and use of hazardous materials above reporting
thresholds must create a Hazardous Materials Business Emergency Plan (HMBEP) as per Chapter
6.95 of the California Health & Safety Code and Title 19, Division 2 of the California Code of
Regulations. The HMBEP requires approval from the County of Riverside CUPA and the
Department of Environmental Health prior to business operation commencement.
• HAZ-2: Phase I and/or Phase II Site Assessment
Projects within the Specific Plan area that involve excavation at locations with recorded Cortese List
sites must undergo a Phase I Environmental Site Assessment, and where necessary, Phase II
sampling. If the Phase I assessment identifies the need for remediation, the project sponsor must
adhere to all remediation and abatement directives specified by the Department of Toxic
Substances Control (DTSC), Regional Water Quality Control Board (RWQCB), or relevant
regulatory agencies.
• HWQ-1: Stormwater Management Practices
Prior to the issuance of City building permits, all projects within the Specific Plan area that disturb
one acre or more of land must prepare a Storm Water Pollution Prevention Plan (SWPPP). This
plan shall outline suitable Best Management Practices (BMPs) for managing and treating runoff from
future development site(s). The applicant is accountable for both preparing and executing the
SWPPP in accordance with NPDES requirements. Additionally, the applicant must submit a Notice
of Intent to the State Water Resource Control Board, obtain a Waste Discharge ID Number (WDID),
and ensure a copy of the SWPPP is present at the development site throughout the construction
phase.
• HWQ-2: Water Conservation Measures
Future development in the Highway 111 corridor must integrate water -saving appliances and
fixtures, such as low -flush toilets, low -flow showerheads, and faucets, in compliance with Section
17921.3 of the Health and Safety Code, Title 20 of the California Administrative Code Section
1601(b), and relevant sections of Title 24 of the California State Code. Additionally, the City will
enforce its Water Efficient Landscape ordinance, requiring development projects within the Specific
Plan area to adopt water -efficient landscaping plans that meet or exceed current criteria. These
measures are aimed at conserving water resources while addressing the needs of residents and
businesses.
• N0I-1: Noise Reduction
All construction activities shall adhere to the City Construction Hours/Quality Assurance Program for
designated construction hours, and equipment with internal combustion engines must be equipped
with manufacturer -recommended mufflers. Future development projects shall use noise -reducing
paving materials, such as open -grade asphalt, for all road surfacing.

Mitigation Monitoring and Reporting
Program (MMRP)
Highway 111 Corridor Specific Plan
Mitigation Monitoring and Reporting Program (MMRP)
The California Environmental Quality Act (CEQA) requires the adoption of feasible mitigation measures to reduce the severity and magnitude of potentially significant environmental impacts associated with project development.
CEQA Guidelines Section 15091(d) states:
When making the findings required in subdivision (a)(1), the CEQA Lead Agency shall also adopt a program for reporting on or monitoring the changes which it has either required in the project or made a condition of approval to avoid or
substantially lessen significant environmental effects. These measures must be enforceable through permit conditions, agreements, or other measures.
CEQA Guidelines Section 15097(a) states:
This section applies when a public agency has made the findings required under paragraph (1) of subdivision (a) of section 15091 to adopt a mitigated negative declaration in conjunction with approving a project. In order to assure that
the mitigation measures and project revisions identified in the negative declaration are implemented, the public agency shall adopt a program for monitoring or reporting on the revisions which it has required in the project and the
measures it has imposed to mitigate or avoid significant environmental effects.
Mitigation Measures
Air Quality
AIR-1: Localized Significance Assessment
Prior to the issuance required discretionary permits, new development projects in the Specific Plan area, if subject to CEQA
compliance, must demonstrate that the proposed development would either not exceed applicable the SCAQMD's Localized
Significance Thresholds (LST) lookup tables or not exceed the respective ambient air quality thresholds for CO, NOx, and PM,o
and PM2.s.
Biological Resources
BIO-1: Assessment of Biological Resources and Worker Environmental Awareness Training
Prior to Project construction activities for all projects covered in this IS/MND, a complete and recent inventory of rare, threatened,
endangered, and other sensitive species located within the Project footprint and within offsite areas with the potential to be
affected, including California Species of Special Concern and California Fully Protected Species (Fish and Game Code § 3511),
will be completed. Species to be addressed should include all those which meet the CEQA definition (CEQA Guidelines § 15380).
The inventory should address seasonal variations in use of the Project area and should not be limited to resident species.
Focused species -specific surveys, completed by a qualified biologist and conducted at the appropriate time of year and time of
day when the sensitive species are active or otherwise identifiable are required. Acceptable species -specific survey procedures
should be developed in consultation with CDFW and the U.S. Fish and Wildlife Service, where necessary. Note that CDFW
generally considers biological field assessments for wildlife to be valid for a one-year period, and assessments for rare plants may
be considered valid for a period of up to three years. Some aspects of the proposed Project may warrant periodic updated
surveys for certain sensitive taxa, particularly if the Project is proposed to occur over a protracted time frame, or in phases, or if
surveys are completed during periods of drought.
An environmental training program should be developed and presented by a qualified biologist to all crew members prior to the
beginning of all Project construction in natural areas planned for development. The training should describe special -status plant
and wildlife species and sensitive habitats that could occur within the Project area, protection afforded to these species and
habitats, and avoidance and minimization measures required to avoid and/or minimize impacts from the project.
All new construction personnel should receive this training before beginning work on this Project. A copy of the training and
training materials should be provided to construction crews for review and approval at least 30 days prior to the start of
construction. As needed, in -field training should be provided to new on -site construction personnel by the qualified biologist or a
qualified individual who should be identified by the qualified biologist, or initial training should be recorded and replayed for new
personnel..
Future development in the Highway 111 Prior to
Corridor must demonstrate compliance Construction

BIO-2: General Measures for Plants and Wildlife
When working in the natural habitat areas, the number of access routes, number and size of staging areas, and the total area of
the activity should be limited to the minimum necessary to achieve the project goal. Routes and boundaries outside of normal
access roads should be clearly delineated through fencing or flagging.
Food, trash, and other solid wastes should be disposed of in Common Raven proof/wildlife proof, covered refuse containers and
regularly removed from the various structures and facilities on a daily basis to avoid offsite dispersal of waste and to avoid
attracting wildlife onto the Project site. Following covered activity work, all trash and debris should be removed from the work
area.
Construction work should avoid direct destruction of burrows through chaining (dragging a heavy chain over an area to remove
shrubs), disking, cultivation, and urban, industrial, or agricultural development.
Project -related excavations greater than 6 inches deep should be secured to prevent wildlife entry and entrapment. Holes and
trenches should be back -filled, securely covered, or fenced. Excavations that cannot be fully secured should incorporate
appropriate wildlife ramp(s) at a slope of no more than a 3:1 ratio (horizontal: vertical, equivalent to a 33.3 percent or 18.4-degree
slope), or other means to allow trapped animals to escape.
Personnel on site should be required to check under their vehicles for sensitive species prior to moving them and should exercise
caution while driving on the Project site.
Before moving, burying, or capping, inspect for wildlife in any construction pipes, culverts, or similar structures that are stored on
the site for one or more nights. Alternatively, cap structures before storing on the work site..
BIO-3: Special Status and Migratory Birds
Construction should be conducted, if possible, during the fall and/or winter months and outside of the avian nesting season
(generally February 1 — August 31) to avoid any direct and or indirect effects to protected nesting birds. Pre -construction surveys
shall focus on both direct and indirect evidence of nesting, including nest locations and nesting behavior. The qualified avian
biologist will make every effort to avoid potential nest predation as a result of survey and monitoring efforts. If active nests are
found during the pre -construction nesting bird surveys, a qualified biologist shall establish an appropriate nest buffer to be marked
on the ground. Nest buffers are species specific and shall be at least 100 feet for passerines and 300 feet for raptors. A smaller or
larger buffer may be determined by the qualified biologist familiar with the nesting phenology of the nesting species and based on
nest and buffer monitoring results. Construction activities may not occur inside the established buffers, which shall remain on -site
until a qualified biologist determines the young have fledged or the nest is no longer active. Active nests and adequacy of the
established buffer distance shall be monitored at least once a week or as needed by the qualified biologist until the qualified
biologist has determined the young have fledged or the Project has been completed. The qualified biologist has the authority to
stop work if nesting pairs exhibit signs of disturbance.
Conduct pre -construction surveys to
check for nesting activity no later than
14 days before Project activities begin.
Construction activities and equipment to
be kept within designated areas. Proper
storage and handling of materials.
Pre -construction surveys, If active nests
or burrows are found within 500 feet of
construction, an ornithologist should
mark a buffer around them, and
construction should avoid these areas
until the young have fledged or nesting
activity has ended. Activities that may
disturb nesting shall be prohibited from
the buffer zone.

BIO-4: Burrowing Owl Surveys
No less than 60 days prior to the start of Project -related activities for all projects covered in the MND, a burrowing owl habitat
assessment shall be conducted by a qualified biologist according to the specifications of the Staff Report on Burrowing Owl
Mitigation (Department of Fish and Game, March 2012 or most recent version) for all projects covered under the MND.
If the habitat assessment demonstrates suitable burrowing owl habitat, then focused burrowing owl surveys shall be conducted by
a qualified biologist in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent version) prior to
vegetation removal or ground -disturbing activities. If burrowing owls are detected during the focused surveys, the qualified
biologist and Project proponent shall begin coordination with CDFW and USFWS immediately, and shall prepare a Burrowing Owl
Avoidance and Monitoring Plan that shall be submitted to CDFW for review and approval prior to commencing Project activities.
The Burrowing Owl Plan shall describe proposed avoidance and monitoring actions, including measures necessary to avoid take
of burrowing owl individuals, nests, and eggs. The Burrowing Owl Plan shall include the number and location of occupied burrow
sites (occupied site means at least one burrowing owl or its sign has been observed within the last three years; may be indicated
by owl sign including feathers, pellets, prey remains, eggshell fragments, or excrement at or near a burrow entrance or perch
site), acres of burrowing owl habitat that will be impacted, details of site monitoring, and details on proposed buffers and other
avoidance measures. If impacts to occupied burrowing owl habitat or burrow(s) or burrowing owl individuals, nests, or eggs
cannot be avoided, appropriate California Endangered Species Act (CESA) authorization (i.e., Incidental Take Permit under Fish
and Game Code section 2081) should be obtained from CDFW prior to commencement of Project activities.
Preconstruction burrowing owl surveys shall be conducted no less than 14 days prior to the start of Project -related activities and
within 24 hours prior to ground disturbance, in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent
version). Preconstruction surveys should be repeated when there is a pause in construction of more than 30 days.
Preconstruction surveys should be performed by a qualified biologist following the recommendations and guidelines provided in
the Staff Report on Burrowing Owl Mitigation. If the preconstruction surveys confirm occupied burrowing owl habitat, Project
activities shall be immediately halted. The qualified biologist shall coordinate with CDFW and prepare a Burrowing Owl Avoidance
and Monitoring Plan that shall be submitted to CDFW and USFWS for review and approval prior to commencing Project activities..
BIO-5: Artificial Light Impacts
Throughout construction and the lifetime operation of all projects covered in the IS/MND the City and Project proponents shall
eliminate all nonessential lighting throughout the Project area and avoid or limit the use of artificial light at night during the hours of
dawn and dusk when many wildlife species are most active. The City and Project proponent shall ensure that all lighting for the
Project is fully shielded, cast downward and directed away from surrounding open -space and agricultural areas, reduced in
intensity to the greatest extent possible, and does not result in lighting trespass including glare into surrounding areas or upward
into the night sky (see the International Dark -Sky Association standards at http://darksky.org/). The City and Project proponent
shall ensure use of LED lighting, proper disposal of hazardous waste, and recycling of lighting that contains toxic compounds with
a qualified recycler.
BIO-6: CDFW Lake and Streambed Alteration (LSA) Program
Prior to construction and issuance of any grading permit, the Project Sponsor shall obtain written correspondence from CDFW
stating that notification under Section 1602 of the Fish and Game Code is not required for the Project, or the Project Sponsor
should obtain a CDFW-executed Lake and Streambed Alteration Agreement, authorizing impacts to Fish and Game Code Section
1602 resources associated with the Project.

1131O-7: Project Adherence to the CVMSHCP
All Conservation Measures that are applicable within Section 4.4 (Required Avoidance, Minimization, and Mitigation Measures)
and Section 9 (Species Accounts and Conservation Measures) of the CVMSHCP should be implemented by the Project to
minimize impacts to plant and wildlife species within the HCP's jurisdiction (CVMSHCP, 2016).
The Project is outside of a designated Conservation Area, and a Joint Review Project is not required. However, the LDMF to the
CVCC is required for development projects. Submission of the LDMF to the CVCC is recommended before building or grading
permits are submitted.
Prior to construction and issuance of any grading permit for all projects covered in the IS/MND, the City shall ensure compliance
with the CVMSHCP and its associated Implementing Agreement and shall ensure the collection of payment of the CVMSHCP
Local Development Mitigation Fee and transfer of fees, at least quarterly and prior to impacts to Covered Species and their
Habitats, to the Coachella Valley Conservation Commission.
Prior to vegetation removal or ground -disturbing activities, for all project areas covered in the IS/MND that contain suitable habitat
for sand -dependent Covered Species, the City will collaborate with the Coachella Valley Conservation Commission to plan and
implement a salvage of sand -dependent Covered Species within the Project site.
Cultural Resources
CRA : Workers Environmental Awareness Program
A Qualified Archaeologist who meets or exceeds the Secretary of Interior's Professional Qualification Standards for archaeology
(NPS, 1983) shall conduct Workers Environmental Awareness Program (WEAP) training on archaeological sensitivity for all
construction personnel prior to the commencement of any ground -disturbing activities. Archaeological sensitivity training shall
include a description of the types of cultural material that may be encountered, cultural sensitivity issues, the regulatory
environment, and the proper protocol for treatment of the materials in the event of a find. The WEAP training document shall
include materials that convey the information noted above, which shall be maintained in an area accessible to all construction
personnel so that it may be reviewed regularly by construction staff.
CR-2: Pre- Excavation Agreement
Prior to the issuance of Grading Permits, the Applicant/Owner shall enter into a pre -excavation agreement, otherwise known as a
Tribal Cultural Resources Treatment and Tribal Monitoring Agreement with consulting Tribal Monitor associated within the area. A
copy of the agreement shall be included in building and development plans and permit applications with the City. The purpose of
this agreement shall be to formalize protocols and procedures between the Applicant/Owner and the consulting Tribal Monitor
associated with the area for the protection and treatment of, including but not limited to, Native American human remains,
funerary objects, cultural and religious landscapes, ceremonial items, and traditional gathering areas and tribal cultural resources
located and/or discovered through a monitoring program in conjunction with the construction of the proposed project, including
additional archaeological surveys and/or studies, excavations, geotechnical investigations, grading, and all other ground
disturbing activities. At the discretion of the consulting Tribal Monitor, artifacts may be made available for 3D scanning/printing,
with scanned/printed materials to be curated at a local repository meeting the federal standards of 36CFR79.
CR-3: Retention of Qualified Archaeologist and Tribal Monitor
Prior to the issuance of a Grading Permits, the Applicant/Owner or Grading Contractor shall provide a written and signed
letter to the City of La Quinta Planning Division stating that a Qualified Archaeologist and consulting Tribal Monitor have
been retained at the Applicant/Owner or Grading Contractor's expense to implement the monitoring program, as described

CR-4: Tribal Cultural Monitor Coordination During Ground Disturbing Activities
The Qualified Archaeologist and consulting Tribal Monitor shall attend all applicable pre -construction meetings with the Genera
Contractor and/or associated subcontractors to present the archaeological monitoring program. The Qualified Archaeologist an
consulting Tribal Monitor shall be present on -site full-time during grubbing, grading, and/or other ground altering activities,
including the placement of imported fill materials or fill used from other areas of the Project site, to identify any evidence of
potential archaeological or tribal cultural resources. All fill materials shall be absent of any and all tribal cultural resources.
CR-5: Controlled Grade Procedure
To detect important archaeological artifacts and cultural resources during monitoring, a "Controlled Grade Procedure" must be
created by a Qualified Archaeologist. This will be done in consultation with the consulting Tribal Monitor, relevant consulting
Tribes, and the Applicant/Owner, and needs approval from City representatives. The procedure will set guidelines for machiner
work in sensitive areas identified during cultural resource monitoring. It will cover aspects like operating speed, removal
increments, weight, and equipment features. A copy of this procedure must be included in the Grading Plan submissions for
Grading Permits.
CR-6: Discovery of Tribal Cultural Resources
The Qualified Archaeologist and consulting Tribal Monitor can stop ground -disturbing activities if undiscovered tribal cult
resources or artifacts are found. All work must cease in the vicinity of any archaeological discovery until the Qualified Archaeolo
and Tribal Monitor can assess the context of the find, including its significance, potential eligibility for the California Registe
Historical Resources (CRHR), and whether the project would have a direct impact on the resource. If buried cultural deposits
encountered, the Archaeologist and Tribal Monitor may request that construction halt nearby and must notify a Quali
Archaeologist within 24 hours for investigation.
Work will be redirected away from these areas for assessment. Minor finds will be documented and secured for later repatriatio
items cannot be securely stored on -site, they may be stored off -site. Minor finds include archaeological materials that are isola
lack context, and are unlikely to indicate a larger or significant site. If the discovered resources are deemed potentially signific
the involved Tribes will be notified for consultation on their respectful treatment. Avoidance of significant resources is preferred,
if not feasible, a data recovery plan may be required. The consulting Tribes will be consulted on this plan as well.
For resources under a data recovery plan, a proper sample will be collected using professional methods, reflecting tribal valL
The Tribal Monitor must be present during any resource collection or cataloging. If the Qualified Archaeologist does not collect
resources, the Tribal Monitor may do so. Ground -disturbing work will not resume until the resources are documented an(
protected.
CR-7: Treatment of Tribal Cultural Resources
The landowner shall relinquish ownership of all cultural resources unearthed during all ground disturbing activities, and from an
previous archaeological studies or excavations on the Project site to the affiliated consulting Tribe, as determined through the
appropriate process, for respectful and dignified treatment and disposition, including reburial at a protected location on -site, in
accordance with the Tribe's cultural and spiritual traditions. All cultural materials that are associated with burial and/or funerary
goods would be repatriated to the Most Likely Descendant as determined by the NAHC per California Public Resources Code
Section 5097.98. No tribal cultural resources shall be subject to curation.
CR-8: Tribal Cultural Monitoring Report
A monitoring report and/or evaluation report, if appropriate, which describes the results, analysis, and conclusions of the
archaeological monitoring program (e.g., data recovery plan) shall be submitted by the Qualified Archaeologist, along with the
consulting Tribal Monitor's notes and comments, to the City of La Quinta Planning Division for approval.

As specified by California Health and Safety Code Section 7050.5, if human remains are found on the Project site during
construction or during archaeological work, the person responsible for the excavation, or his or her authorized representative,
shall immediately notify the Riverside County Coroner's Office by telephone. No further excavation or disturbance of the site or
any nearby area reasonably suspected to overlie adjacent remains shall occur until the Coroner Medical Examiner has made the
necessary findings as to origin and disposition pursuant to Public Resources Code 5097.98. If such a discovery occurs, a
temporary construction exclusion zone shall be established surrounding the area of the discovery so that the area would be
protected, and consultation and treatment could occur as prescribed by law. If suspected Native American remains are
discovered, the remains shall be kept in -situ, or in a secure location in close proximity to where they were found, and the analysis
of the remains shall only occur on -site in the presence of a Tribal Monitor. By law, the Coroner Medical Examiner shall determine
within two working days of being notified if the remains are subject to his or her authority. If the Coroner Medical Examiner
identifies the remains to be of Native American ancestry, he or she shall contact the NAHC within 24 hours. The NAHC shall
make a determination as to the Most Likely Descendent. If human remains are discovered, notify the consulting Tribe's Tribal
Historic Preservation Officer.
Geology
GEO-1: Protect Paleontological Resources during Construction Activities
Prior to ground disturbing activities, all field personnel will receive training on paleontological resources, including potential fossils
that may be discovered and response steps, while a qualified paleontologist will prepare a Paleontological Resources Monitoring
and Mitigation Plan (PRMMP).
If fossils (like bones, teeth, or well-preserved plants) are found during construction, the City will stop work within 50 feet and notify
a paleontologist to document and assess the find. The paleontologist may allow work to continue or recommend salvaging the
fossils if necessary and will suggest appropriate treatment methods. Collected fossils will be sent to an accredited institution for
curation and preservation.
All earth -moving operations deeper than two feet must have a qualified paleontological monitor. Continuous monitoring is needed
if fossil -rich lakebed sediments are found. The monitor can stop work to identify and salvage fossils and may halt equipment for
large specimens. A monitoring plan must be submitted to the City before any permits are issued or soil is disturbed. Grading and
excavation must comply with La Quinta Code and regulations.
After ground disturbing activities and any necessary fossil curation, the project paleontologist will prepare a final report detailing the
results of the PRMMP.
Hazards
HAZ-1: Hazardous Materials Handling and Planning
New development projects in the Specific Plan area must comply with local, state, and federal regulations by submitting
development plans and permits to the City for review. Projects intending to use or store hazardous materials must prepare a Spill
Prevention Countermeasure Contingency Plan (SPCC) outlining spill containment protocols, along with maintaining an onsite
SPCC spill kit. Additionally, developments proposing storage and use of hazardous materials above reporting thresholds must
create a Hazardous Materials Business Emergency Plan (HMBEP) as per Chapter 6.95 of the California Health & Safety Code
and Title 19, Division 2 of the California Code of Regulations. The HMBEP requires approval from the County of Riverside CUPA
and the Department of Environmental Health prior to business operation commencement.
HAZ-2: Phase I and/or Phase II Site Assessment
Projects within the Specific Plan area that involve excavation at locations with recorded Cortese List sites must undergo a Phase I
Environmental Site Assessment, and where necessary, Phase II sampling. If the Phase I assessment identifies the need for
remediation, the project sponsor must adhere to all remediation and abatement directives specified by the Department of Toxic
Substances Control (DTSC), Regional Water Quality Control Board (RWQCB), or relevant regulatory agencies.

La Quinta 15-acre Mixed Use Development — Project no. 11219378
Biological Reconnaissance Site Visit to Support
CEQA IS/MND
The City of La Quinta (City) is proposing a mixed -use development in La Quinta, California (hereafter
Project). To assist with preparation of the Project's Initial Study/Mitigated Negative Declaration (IS/MND) in
accordance with the California Environmental Quality Act (CEQA), GHD evaluated the potential for
sensitive biological resources (federal or state listed or state special status plants and wildlife, Sensitive
Natural Communities, and wetlands) to occur within the Project area and potential impacts to these
resources. Based on occurrence records, habitat availability, and the reconnaissance -level site visit, special
status wildlife species have a potential to occur in the Project area. Special status plants may have the
potential to occur but would require protocol -level surveys in appropriate blooming seasons to determine
presence/absence. No impacts to jurisdictional wetlands or waters, or Sensitive Natural Communities are
expected.

Sara Moriarty -Graves
Wildlife Biologist
The Power of Commitment
11219378
1. Introduction
The City of La Quinta (City) is proposing a mixed -use development in La Quinta, California (hereafter
Project; Appendix A, Figure 1). The proposed Project plan includes development of up to 280 low-income
apartment units along the north side of the parcel, and a commercial development on the south side of the
parcel, along Highway 111. As part of the development, Corporate Center Drive would be extended to be
continuous and separate the residential and commercial portions of the Project area.
The 280 residential units are proposed to be a mix of one, two and three bedrooms and would require
approximately 350-375 parking spaces. The average unit would be about 850 square feet in area. The
residential buildings would be four stories with the units accessed off of a central interior hallway. Each
story would have approximately 62 or 63 units. The parking spaces would be provided in three levels of
parking (two story structure with parking on the roof). Bridges would be provided to link the 2nd and 3rd
levels of parking to the corresponding residential level. The complex would include common amenities such
as a swimming pool, play structures, common areas, operational and maintenance offices, and trash
rooms. The commercial development would provide an approximate 85,000 square foot large retail building
and 15,000 square foot separate drive through building. The sizes and configuration may vary based on the
final commercial establishments.
GHD evaluated the potential for sensitive biological resources (federally or state listed or state special
status plants and wildlife, Sensitive Natural Communities [SNCs], and wetlands) to occur within the Project
Study Boundary (PSB) and Biological Study Area (BSA; defined as the PSB and a 100-foot buffer to
account for associated impacts from the Project; Appendix A, Figure 2). In addition, potential Project
impacts to these resources were evaluated.
Special status species and resources are the primary focus of this evaluation. Common species or
resources without special protections are not considered. The purpose of this biological reconnaissance
technical memorandum is to document the results of the February 4, 2023, site visit and provide information
to support the Project's Initial Study/Mitigated Negative Declaration (IS/MND) in accordance with the
California Environmental Quality Act (CEQA) to provide a programmatic -level review of potential
environmental impacts associated with the proposed Project.
1.1 Project Location and Existing Setting
The BSA is located in the City of La Quinta, which is in the County of Riverside, in between Highway 111
and the Whitewater River (Appendix A, Figure 2). Land cover is classified as shrub/scrub and is
surrounded by open developed space to high level of intensity (USGS 2016).
The City is located in the Coachella Valley, which is in between the Santa Rosa Mountains and Jacinto
Mountains (to the west), Joshua Tree National Park (to the east), and approximately 40 miles from the
Salton Sea (to the southeast). The BSA is located within the Whitewater River Watershed. The PSB is 15
acres, and is surrounded by retail stores, businesses, Highway 111, and other roads. The northern section
of the BSA borders the Whitewater River. The landscape surrounding the BSA is highly urbanized and
developed, with high amounts of vehicular traffic.
2. Survey Methods
The following subsections summarize the desktop and field methods utilized to produce this technical
memorandum.
2.1 Database Searches (CNDDB, CNPS, EFH, IPaC, NOAA Critical
Habitat, and NWI)
A database search for sensitive biological resource records in the Project vicinity was conducted by GHD
on January 24, 2023. Database searches (Appendix B) included the California Natural Diversity Database
(CNDDB; CDFW 2023a), California Native Plant Society (CNPS) Inventory of Rare and Endangered
11219378
Vascular Plants (CNPS 2023), U.S. Fish and Wildlife Service (USFWS) Information for Planning and
Consultation (IPaC; USFWS 2023), National Oceanic and Atmospheric (NOAA) Fisheries Essential Fish
Habitat (EFH; NOAA 2023a), and NOAA Critical Habitat (NOAA 2023b).
The search encompassed the La Quinta U.S. Geological Survey 7.5-minute quadrangle and surrounding
eight quads (Rancho Mirage, Cathedral City, Myoma, West Berdoo Canyon, Indio, Valerie, Martinez
Mountain, and Toro Peak). Appendix A, Figure 3 shows all special status species records tracked by the
CNDDB that are known to occur within a three-mile radius of the Project. A search of the USFWS National
Wetlands Inventory (NWI) for the Project vicinity was completed on January 24, 2023 (Appendix A, Figure
4; USFWS 2023b).
2.2 Field Survey
A reconnaissance field survey was conducted by Sara Moriarty -Graves, GHD Wildlife Biologist, on
February 4, 2023, from 09:30 to 11:00. Weather conditions were clear and with light air (Beaufort scale 1),
about 60 to 65 degrees Fahrenheit. The survey included walking the entire PSB (Appendix A, Figure 2).
The BSA was assessed visually from the public street right-of-way. The survey methods were intended to
assess the potential for special status resources and habitats that occur within the BSA. The survey
involved a physical search of the area, including visual inspections of the ground, holes, and vegetation for
the presence of any wildlife species, special status plant species, or SNCs. Additionally, the bark of
vegetation and the ground layer under vegetation were visually inspected for evidence of wildlife species,
such as feathers, pellets, whitewash, scat, tracks, etc. No protocol -level surveys for wetlands, SNCs,
special status plants, or wildlife were conducted.
3. Results
The following sub -sections summarize the results of the desktop research and field survey performed for
this technical memorandum.
3.1 Summary of General Biological Resources
The PSB is a vacant lot located within the city of La Quinta and is surrounded by commercial businesses.
There was litter, and signs of foot traffic and vehicle use observed within the BSA. The dominant vegetation
within the PSB consisted of creosote (Larrea tridentata). The BSA is bordered to the north by the
channelized Whitewater River. No flowing water and minimal moisture within the riverbed was observed.
Commercial businesses surround the BSA to the east, south, and west. The other side of the Whitewater
River is also developed.
Although the BSA is within a developed landscape, there are shrubs and dune habitat that may support
special status species. Many small mammal burrows were observed within the BSA, which can be used by
other taxa such as birds and reptiles. The BSA also supports common avian species protected by the
federal Migratory Bird Treaty Act (MBTA) and California Fish and Game Code (FGC). Photos from the site
visit are included in Appendix C (Site Visit Photos). Lists of all species observed within the BSA are
provided in Appendix D, Tables D1 to D4.
3.2 Wetlands and Waters
The Whitewater River is adjacent to the northern portion of the BSA. The section of river adjacent to the
BSA is classified as a riverine intermittent streambed that is intermittently flooded (USFWS 2023b).
However, the Whitewater River in the Project vicinity is channelized and is highly modified from its original
form. To reduce sedimentation and maintain flows, it is frequently maintained by the Coachella Valley
Water District (City of La Quinta 2017). It is characterized as having a mixture of earthen and concrete
bottom and slopes and supports some vegetation growth. The channel conveys surface storm water runoff
during rain events (City of La Quinta 2017). During the site visit, there was limited puddled water observed
within the river (Appendix C, Site Visit Photos). No flowing water was observed, and there were signs of
vehicular use within the riverbed.
11219378
The Project does not involve alteration of the Whitewater River, including the channel and floodplain. There
will be no impact to the Whitewater River or jurisdictional wetlands.
3.3 Sensitive Natural Communities (SNCs)
A query of CNDDB returned multiple locations of Desert Fan Palm Oasis Woodland (Washingtonia filifera)
SNC (G3, S3.2) in the nine quads surrounding the PSB; however, the nearest Desert Fan Palm Oasis to
the PSB is over five miles to the northeast. No native fan palms are present in the PSB.
The PSB is mainly vegetated by Creosote Bush Scrub (Larrea tridentata), a natural community which is not
considered sensitive by CDFW (G5, S5).
The Project would not impact any SNCs, as none are present
3.4 Habitat Conservation Plans and Natural Community
Conservation Plans
Habitat Conservation Plans (HCPs) and Natural Community Conservation Plans (NCCPs) are site -specific
plans to address effects on sensitive species of plants and animals. The BSA is within the Coachella Valley
Multiple Species Habitat Conservation Plan (CVMSHCP), which is an HCP and NCCP implemented by the
Coachella Valley Conservation Commission (CVCC; CDFW 2023b, CVCC 2023). The City of La Quinta has
been a participant in the CVMSHCP since 1996. If the project qualifies, the signatories to the CVMSHCP
are able to obtain coverage for incidental take for the 21 wildlife and plant species that the CVMSHCP
covers (CVCC 2023).
The Project is outside of a designated Conservation Area, and a Joint Review Project is not required.
However, the Local Development Mitigation Fee (LDMF) to the CVCC is required for development projects.
Submission of the LDMF to the CVCC is recommended before building or grading permits are submitted.
3.5 Critical Habitat
The BSA does not overlap any federally designated critical habitat (Appendix B, IPaC Report). No impact
would result.
3.6 Habitat Connectivity and Access
Wildlife corridors refer to established migration routes commonly used by resident and migratory species for
passage from one geographic location to another. Maintaining the continuity of established wildlife corridors
is important to: a) sustain species with specific foraging requirements, b) preserve a species' distribution
potential, and c) retain diversity among many wildlife populations. Therefore, resource agencies consider
wildlife corridors to be a sensitive resource.
The Project is approximately seven miles from the nearest "essential connectivity area" and one mile from a
"natural landscape block" and "small natural landscape area" identified by the California Habitat
Connectivity Project (CDFW 2022c). The BSA is surrounded by existing development, Highway 111, and
the highly modified Whitewater River. Due to the level of development existing surrounding the BSA, there
would be no impact to the habitat access, connectivity, or migratory corridors of wildlife species. Habitat in
the Project vicinity is highly fragmented. No new barriers to terrestrial wildlife movement would result from
the Project, and the Project would not substantially interfere with migratory birds, bats, or other species.
3.7 Special Status Plants
The database scoping detailed in Section 2.1 produced a total of 66 plant species known to occur in the
nine USGS quads surrounding the PSB. Based on species specific habitat requirements and habitat
availability within the PSB, three species have a low potential to occur, and seven have a moderate
potential to occur (Table 1). Due to the disturbed and isolated nature of the habitat in the PSB, no special
status plant species have a high potential to occur.
No special status plant species were observed during the site visit on February 4, 2023; however, no
protocol level surveys have been conducted and the site visit was outside of the blooming season for some
11219378
plant species with potential to occur in the PSB. Protocol level surveys will be required to determine if
special status plants are present. A list of all plant species detected during the reconnaissance -level site
visit are presented in Appendix D, Table D1.

Potential to Occur:
No potential: Habitat in and adjacent to the PSB is clearly unsuitable for the species requirements (cover, substrate, elevation, hydrology, plant community, site history, disturbance
regime).
Low potential: Few of the habitat components meeting the species requirements are present, and/or the majority of habitat on and adjacent to the site is unsuitable or of very poor
quality. The species is not likely to be found in the PSB.
Moderate potential: Some of the habitat components meeting the species requirements are present, and/or only some of the habitat on or adjacent to the site is unsuitable. The
species has a moderate probability of being found in the PSB.
High potential: All of the habitat components meeting the species requirements are present and/or most of the habitat on or adjacent to the site is highly suitable. The species has a
high probability of being found on in the PSB.

3.8 Special Status Wildlife
The database scoping detailed in Section 2.1 returned a total of 86 species (Table 2). The potential for
sensitive wildlife species to occur was determined based on existing data and the reconnaissance level site
visit. Special status species are federally and/or state listed, a CDFW Species of Special Concern, CDFW
Fully Protected, on the CDFW Special Animals List, or any combination of these.
The Coachella Valley Fringe -toed Lizard (federally threatened and state endangered) is a listed reptile
species with a moderate potential to occur within the BSA based on recent nearby observations (Naturalist
2023). In addition, there is one special status rodent species (Coachella Valley Round -tailed Ground
Squirrel), six bird species, one other reptile species (Flat -tailed Horned Lizard), and one insect (Coachella
Valley Giant Sand Treader Cricket) with a moderate potential to occur (Table 2). The Burrowing Owl is a
covered species under the CVMSHCP, but is afforded additional protections under FGC and the MBTA and
would require additional minimization measures. According to the CVMSHCP, authorization of take for all
species with a moderate potential to occur, except the six bird species, can be obtained through
compliance with the CVMSHCP and the LDMF paid to the CVCC (CVCC 2023). Minimization measures to
reduce impacts to bird species are included in Section 5. Although compliance with the CVMSHCP
authorizes take for the covered species, state and federal regulations could require additional minimization
measures in subsequent review of CEQA documents.
Terrestrial wildlife observed on site are included in Appendix D, Table D2. A lizard and ground squirrel
were briefly observed during the site visit and were not able to be identified to species. A list of all bird
species detected during the site visit and their associated breeding codes are presented in Appendix D,
Tables D3 and D4. As many neotropical avian species have migrated south by fall, Table D4 is not a
comprehensive list of all species that could occur throughout the breeding season. In addition, no protocol -
level surveys have been conducted.
Based on existing habitat and available data, the BSA may support special status species and does
support common species. With implementation of the proposed avoidance and minimization measures
(Section 5), in addition to compliance with the CVMSHCP, impacts to special status wildlife species would
be less than significant.

Other Statuses (other federal or state listings may include):
CDFW FP (CDFW Fully Protected Animal): "This classification was the State of California's initial effort to identify and provide additional protection to those animals that were rare
or faced possible extinction. Lists were created for fish, amphibians and reptiles, birds and mammals. Most of the species on these lists have subsequently been listed under the
state and/or federal endangered species acts." (CDFW 2023c);
CDFW SSC (CDFW Species of Special Concern): "It is the goal and responsibility of the Department of Fish and Wildlife to maintain viable populations of all native species. To this
end, the Department has designated certain vertebrate species as 'Species of Special Concern' because declining population levels, limited ranges, and/or continuing threats have
made them vulnerable to extinction. The goal of designating species as 'Species of Special Concern' is to halt or reverse their decline by calling attention to their plight and
addressing the issues of concern early enough to secure their long-term viability" (CDFW 2023c);
CDFW WL (California Department of Fish and Wildlife Watch List): "The CDFW maintains a list consisting of taxa that were previously designated as "Species of Special Concern"
but no longer merit that status, or which do not yet meet SSC criteria, but for which there is concern and a need for additional information to clarify status" (CDFW 2023c).
Potential to Occur:
No potential: Habitat in and adjacent to the PSB is clearly unsuitable for the species requirements (cover, substrate, elevation, hydrology, plant community, site history, disturbance
regime).
Low potential: Few of the habitat components meeting the species requirements are present, and/or the majority of habitat on and adjacent to the site is unsuitable or of very poor
quality. The species is not likely to be found in the PSB.
Moderate potential: Some of the habitat components meeting the species requirements are present, and/or only some of the habitat on or adjacent to the site is unsuitable. The
species has a moderate probability of being found in the PSB.
High potential: All of the habitat components meeting the species requirements are present and/or most of the habitat on or adjacent to the site is highly suitable. The species has a
high probability of being found on in the PSB.
Present: Detected or documented on -site.
11219378 32
4. Discussion
Based on the reconnaissance -level site visit on February 4, 2023, and review of existing data, the BSA may
provide suitable habitat for special status wildlife species. In addition, several common avian species were
observed on -site that are protected by the MBTA and FGC (Appendix D, Table D2 and D4). Vegetation
within and directly adjacent to the BSA could provide suitable nesting habitat for migratory bird species, and
other common terrestrial species.
No special status plant species were observed during the site visit on February 4, 2023 (Appendix D,
Table D1); however, no protocol level surveys have been conducted and the site visit was outside of the
blooming season for some plant species with potential to occur in the PSB. Protocol level surveys will be
required to determine if special status plants are present. No SNCs were observed during the site visit.
Since the Project is within the CVMSHCP's boundaries, and within an authorized take area, mitigation for
four special status species would be accounted for with compliance with the CVMSHCP and through
purchase of LDMF's from the CVCC (CVCC 2023). However, the CVMSHCP does not cover the six special
status bird species with a moderate potential to occur, nor birds protected by the MBTA and FGC.
Additional measures are recommended in Section 5 for these bird species.
5. Proposed Avoidance and Minimization Measures
All Conservation Measures that are applicable within Section 4.4 (Required Avoidance, Minimization, and
Mitigation Measures) and Section 9 (Species Accounts and Conservation Measures) of the CVMSHCP
should be implemented by the Project to minimize impacts to plant and wildlife species within the HCP's
jurisdiction (CVMSHCP 2016). Specifically, species with a moderate potential to occur that are
encompassed within the CVMSHCP include: Palm Springs Round -tailed Ground Squirrel, Burrowing Owl,
Flat -tailed Horned Lizard, Coachella Valley Fringe -tailed Lizard, and the Coachella Giant Sand Treader
Cricket (CDFW 2023b).
In addition, the following measures are recommended for implementation to reduce impacts to a less than
significant level.
5.1 Measure 1310-1: Worker Environmental Awareness Training
An environmental training program should be developed and presented by a qualified biologist to all crew
members prior to the beginning of all Project construction. The training should describe special -status plant
and wildlife species and sensitive habitats that could occur within the BSA, protection afforded to these
species and habitats, and avoidance and minimization measures required to avoid and/or minimize impacts
from the project.
All new construction personnel should receive this training before beginning work on this project. A copy of
the training and training materials should be provided to construction crew for review and approval at least
30 days prior to the start of construction. As needed, in -field training should be provided to new on -site
construction personnel by the qualified biologist or a qualified individual who should be identified by the
qualified biologist, or initial training should be recorded and replayed for new personnel.
5.2 Measure 1310-2: Protect Special Status Plants
Avoidance measures for special status plant species are addressed collectively for all species. Impacts to
special -status plant species present or likely to be present onsite shall be minimized, avoided, and (if
necessary) compensated by complying with the following:
- Seasonally appropriate pre -construction surveys for special status plant species should occur prior
to construction within the planned area of disturbance for the project, during the appropriate
blooming time (spring and summer) for the target species. Survey methods should comply with
CDFW rare plant survey protocols and should be performed by a qualified field botanist. Surveys
The Power of Commitment
11219378 33
should be modified to include detection of juvenile (pre -flowering) colonies of perennial species
when necessary. Any populations of special status plant species that are detected should be
mapped. Populations should be flagged if avoidance is feasible and if populations are located
adjacent to construction areas.
- The locations of any special status plant populations to be avoided should be clearly identified in
the contract documents (plans and specifications).
- If special status plant populations are detected where construction would have unavoidable
impacts, a compensatory conservation plan should be prepared and implemented in coordination
with CDFW. Such plans may include salvage, propagation, on -site reintroduction in restored
habitats, and monitoring.
5.3 Measure Bio-3: General Measures for Plants and Wildlife
- When working in the dune habitat areas, the number of access routes, number and size of staging
areas, and the total area of the activity should be limited to the minimum necessary to achieve the
project goal. Routes and boundaries outside of normal access roads should be clearly delineated
through fencing or flagging.
- Food, trash, and other solid wastes should be disposed of in Common Raven proof/wildlife proof,
covered refuse containers and regularly removed from the various structures and facilities on a
daily basis to avoid offsite dispersal of waste and to avoid attracting wildlife onto the project site.
Following covered activity work, all trash and debris should be removed from the work area.
- Construction work should avoid direct destruction of burrows through chaining (dragging a heavy
chain over an area to remove shrubs), disking, cultivation, and urban, industrial, or agricultural
development.
- Project -related excavations greater than 6 inches deep should be secured to prevent wildlife entry
and entrapment. Holes and trenches should be back -filled, securely covered, or fenced.
Excavations that cannot be fully secured should incorporate appropriate wildlife ramp(s) at a slope
of no more than a 3:1 ratio (horizontal: vertical, equivalent to a 33.3 percent or 18.4-degree slope),
or other means to allow trapped animals to escape.
- Personnel on site should be required to check under their vehicles for sensitive species prior to
moving them and should exercise caution while driving on the Project site.
- Before moving, burying, or capping, inspect for wildlife in any construction pipes, culverts, or similar
structures that are stored on the site for 1 or more nights. Alternatively, cap structures before
storing on the work site.
5.4 Measure Bio-4: Special Status and Migratory Birds
Potential Project impacts to six special status birds and common birds protected by the MBTA and FGC
during construction may include visual disturbance, habitat destruction, and noise disturbance. The
following measures are proposed to avoid potential impacts.
Construction should be conducted, if possible, during the fall and/or winter months and outside of
the avian nesting season (generally February 1 — August 31) to avoid any direct effects to protected
birds.
A qualified ornithologist should conduct pre -construction surveys within the vicinity of the BSA, to
check for nesting or burrowing activity of native birds and to evaluate the site for presence of
raptors and special status bird species. The ornithologist should conduct at minimum a one -day
pre -construction survey within the seven-day period prior to construction activities beginning. If
construction work lapses for seven days or longer during the breeding season, a qualified
ornithologist should conduct a supplemental avian pre -construction survey before Project work is
reinitiated.
- If active nests or burrows are detected within the construction footprint or up to 500 feet from
construction activities, the ornithologist should flag a buffer around each nest (assuming property
access). Construction activities should avoid nest or burrows sites until the ornithologist determines
11219378 34
that the young have fledged or nesting activity has ceased. If nests or burrows are documented
outside of the construction (disturbance) footprint, but within 500 feet of the construction area,
buffers would be implemented as needed (buffer size dependent on species). Buffer sizes for
common species would be determined on a case -by -case basis in consultation with the CDFW
and, if applicable, with USFWS. Buffer sizes would consider factors such as:
• (1) noise and human disturbance levels at the construction site at the time of the survey
and the noise and disturbance expected during the construction activity;
• (2) distance and amount of vegetation or other screening between the construction site and
the nest; and
• (3) sensitivity of individual nesting species and behaviours of the nesting birds.
If active nests or burrows are detected during the survey, the qualified ornithologist should monitor
all nests or burrows at least once per week to determine whether birds are being disturbed.
Activities that might, in the opinion of the qualified ornithologist, disturb nesting activities (e.g.,
excessive noise), should be prohibited within the buffer zone until such a determination is made. If
signs of disturbance or distress are observed, the qualified ornithologist should immediately
implement adaptive measures to reduce disturbance. These measures may include, but are not
limited to, increasing buffer size, halting disruptive construction activities in the vicinity of the nest
until fledging is confirmed or nesting activity has ceased, placement of visual screens or sound
dampening structures between the nest and construction activity, reducing speed limits, replacing
and updating noisy equipment, queuing trucks to distribute idling noise, locating vehicle access
points and loading and shipping facilities away from noise -sensitive receptors, reducing the number
of noisy construction activities occurring simultaneously, and/or reorienting and/or relocating
construction equipment to minimize noise at noise -sensitive receptors.
If Burrowing Owls are detected, buffers following guidance from Section 4 of the CHMSHCP would
be adopted. The buffer distance during the non -breeding season is 160 feet, and 250 feet during
the breeding season. Buffers would be staked and flagged. No Project work would be permitted
within the established buffered distances. No development or operation and maintenance activities
would be permitted within the buffer until the young are no longer dependent on the burrow. If the
burrow is unoccupied, the burrow could be made inaccessible to owls, and the Covered Activity
may proceed.
6. Conclusion
Based on occurrence records, habitat availability, and the reconnaissance -level site visit, special status
wildlife and plant species may occur within the BSA. With compliance with the CVMSHCP (see Section
3.4), and the recommended minimization measures in Section 5, impacts are expected to be less than
significant. The minimization measures are recommended to be implemented within the Project's IS/MND
document and associated Mitigation Monitoring and Reporting Program.

EFH Data Notice
EFH Mapper Report
Essential Fish Habitat (EFH) is defined by textual descriptions contained in the fishery management plans developed by the regional fishery
management councils. In most cases mapping data can not fully represent the complexity of the habitats that make up EFH. This report should
be used for general interest queries only and should not be interpreted as a definitive evaluation of EFH at this location. A location -specific
evaluation of EFH for any official purposes must be performed by a regional expert. Please refer to the following links for the appropriate
regional resources.

Project Code: 2023-0037535
Project Name: La Quinta PW HWY 111 Planning and Engineering Project
January 24, 2023
Subject: List of threatened and endangered species that may occur in your proposed project
location or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and final designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. The species list fulfills the
requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the
Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website at regular intervals during project planning and
implementation for updates to species lists and information. An updated list may be requested
through the ECOS-IPaC system by completing the same process used to receive the enclosed list.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A biological assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a biological
01/24/2023
evaluation similar to a biological assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a biological assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation, that
listed species and/or designated critical habitat may be affected by the proposed project, the
agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service
recommends that candidate species, proposed species and proposed critical habitat be addressed
within the consultation. More information on the regulations and procedures for section 7
consultation, including the role of permit or license applicants, can be found at the Fish and
Wildlife Service's Endangered Species Consultation website at:
https://www.fws.gov/endangered/what-we-do/faq.html
Migratory Birds: In addition to responsibilities to protect threatened and endangered species
under the Endangered Species Act (ESA), there are additional responsibilities under the
Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to
protect native birds from project -related impacts. Any activity, intentional or unintentional,
resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by
the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more
information regarding these Acts see https://www.fws.gov/birds/policies-and-regulations.php.
The MBTA has no provision for allowing take of migratory birds that may be unintentionally
killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to
comply with these Acts by identifying potential impacts to migratory birds and eagles within
applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan
(when there is no federal nexus). Proponents should implement conservation measures to avoid
or minimize the production of project -related stressors or minimize the exposure of birds and
their resources to the project -related stressors. For more information on avian stressors and
recommended conservation measures see https://www.fws.gov/birds/bird-enthusiasts/threats-to-
birds.php.
In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies
to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities
that might affect migratory birds, to minimize those effects and encourage conservation measures
that will improve bird populations. Executive Order 13186 provides for the protection of both
migratory birds and migratory bird habitat. For information regarding the implementation of
Executive Order 13186, please visit https://www.fws.gov/birds/policies-and-regulations/
executive-orders/e0-13186. php.
We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Code in the header of
this letter with any request for consultation or correspondence about your project that you submit
to our office.

Re: Cultural Resources Records Search for City of La Quinta Highway I I I Corridor Specific Plan
Proiect
Dear Ryder Bwliss,
We received your request on November 28, 2023, for a cultural resources records search for the City of La
Quinta Highway l I I Corridor Specific Plan project, located in Sections 19, 30, 29, and 28, T.5S, R.7E,
SBBM, in the southern area of the Whitcwatcr River in the City of La Quinta in Riverside County. We
have reviewed our maps, records, and reports against the project area defined on the map you provided.
Our records indicate that 92 cultural resource studies have been conducted within your project area.
Fifty-six cultural resource properties are recorded within the boundaries of the project area.
Additional sources of information consulted are identified below.
National Register of Historic Places (NRHP): no listed properties are located within the boundaries of the
project area.
California Office of Historic Preservation (OHP), Archaeological Resources Directory (ARD): One
property is listed as determined eligible for listing in the NRHP (P-33-001178 [CA-RIV-001178] La Quinta
Evac. CH. AD.)
California Office of Historic Preservation (OHP), Built Environment Resources Directory (BERD): Two
properties are listed as recognized as a historically significant by local government (P-33-007263, PT.
Happy Ranch and P-33-023955, PT. Happy Ranch). One property is listed as not eligible for listing or
designation as specified (P-33-017259, Coachella Valley Stonnwater Channel). One property is listed as
not evaluated for NRHP or CRHR or needs revaluation (P-33-007264, 46370 Cameo Palms Dr).
Note: not all properties in the California Historical Resources Information System are listed in the OHP
ARD and BERD; the ARD and BERD comprise lists of properties submitted to the OHP for review.
The 1941 USGS Toro Peak 15' minute series, 1959 USGS La Quinta 7.5' minute series, and 1959 USGS
Palm Desert 15' minute series topographic maps show about 30 historical structures or features present
within the boundaries of the project area.
Based on the information reviewed, 56 cultural resources properties have been recorded within the
boundaries of the project area, thus additional cultural resources may be present within the boundaries of
the project area. It is recommended that these resources undergo an evaluation of their significance to
determine appropriate mitigation measures. However, this assessment does not rule out the possible
presence of previously unidentified cultural resources, thus, it is recommended that the project area be
examined systematically by a cultural resource professional to identify all historical, archaeological, and
cultural heritage resources that have not been recorded, and to provide recommendations regarding their
significance and management prior to any development of the project area. Persons involved in
development of the project area should be sensitive to the significant and irreplaceable nature of cultural
resources. A statewide list of cultural resources consultants can be found online at http://chrisinfo.org.
State and federal law requires that if any cultural resources are found during construction, work is to stop
and the lead agency and a cultural resources professional be consulted to determine the importance of the
find and its appropriate management.
Due to processing delays and other factors, not all of the historical resource reports and resource records
that have been submitted to the Office of Historic Preservation are available via this records search.
Additional information may be available through the federal, state, and local agencies that produced or paid
for historical resource management work in the search area. Additionally, Native American tribes have
historical resource information not in the California Historical Resources Information System (CHRIS)
Inventory, and you should contact the California Native American Heritage Commission for information
on local/regional tribal contacts.
The California Office of Historic Preservation (OHP) contracts with the California Historical Resources
Information System's (CHRIS) regional Information Centers (ICs) to maintain information in the CHRIS
inventory and make it available to local, state, and federal agencies, cultural resource professionals, Native
American tribes, researchers, and the public. Recommendations made by the IC coordinators or their staff
regarding the interpretation and application of this information are advisory only. Such recommendations
do not necessarily represent the evaluation or opinion of the State Historic Preservation Officer in carrying
out the OHP's regulatory authority under federal and state law.

Hiahwav 111 SP Proiect Description
The project area is located in the City of La Quinta and spans the Highway 111 corridor
from approximately Washington Street on the west end to Jefferson Street on the east;
and from a Whitewater flood control channel/wash on the north to Avenue 47, and Vista
Coralina Lane on the south.
Development along Highway 111 in the project area comprises a mix of uses, principally
commercial (e.g., big box retail, strip center, grocery, restaurants, auto dealers) and large
surface parking lots. Some residential uses are located to the south. There are a few
vacant parcels scattered throughout the project area. Landscaping consists of street trees
and other ornamental xeriscape. Transportation facilities are largely improved with a full
street network, curbs and sidewalks, and crosswalks at major intersections.
The proposed Highway 111 Corridor Specific Plan provides guidance for implementing
development within the planning area. The Specific Plan furthers the objectives of the
City of La Quinta General Plan (hereinafter "General Plan") by providing a more detailed
planning document for development of specific sites and streetscape improvements.

Re: Highway 111 Specific Plan - SP2022-0002
Dear Ms. Cheri Flores,
03-003-2025-002
The Agua Caliente Band of Cahuilla Indians (ACBCI) appreciates your efforts to include the
Tribal Historic Preservation Office (THPO) in the Highway 111 Specific Plan project. The
project area is not located within the boundaries of the ACBCI Reservation. However, it is
within the Tribe's Traditional Use Area. A records check of the ACBCI registry identified
previous surveys in the area that were positive for the presence of cultural resources. In
consultation, the ACBCI THPO requests the following:
* Please send all consultation letters to ACBCI-THPO@aguacaliente.net.
* Instead of "Traditionally and Culturally Affiliated" Native American monitor,
consulting Native American monitor would make sense for tribes in consultation
requesting their own monitors.
* There are several TCR's within the project boundary: CA-RIV-8835 is within
DJN-I, CA-RIV-5832 is adjacent to DJS-I, CA-RIV-6190 and CA-RIV-2936 is
partially within AND-01, CA-RIV-4752 is within ADS-2. Those are counting for
the undeveloped areas within the project.
* Please send us a copy of the Archaeological report from recent surveys if there
were any and include consulting tribes into surveys for projects.
Again, the Agua Caliente appreciates your interest in our cultural heritage. If you have questions
or require additional information, please call me at (760) 883-1137. You may also email me at
ACBCI-THPO@aguacaliente.net.

Public and Agency Comments
Public and Agency Comments
The City of La Quinta, serving as the CEQA Lead Agency, prepared a Draft Initial Study/Mitigated
Negative Declaration (IS/MND) for the Highway 111 Corridor Specific Plan Project. CEQA requires a
30-day public review period for the Draft IS/MND document. The public comment period allows public
agencies and interested parties the opportunity to review and comment on the document.
The Draft IS/MND was released for public comment on May 19, 2025, and the review period closed
on June 19, 2025. In accordance with the requirements of CEQA, the City of La Quinta provided a
Notice of Intent (NOI) to adopt a Mitigated Negative Declaration to the public, responsible agencies,
and the San Diego County Clerk. The City of La Quinta published a notice in The Desert Sun (a
newspaper of general circulation in the area affected by the proposed Project). The Draft IS/MND was
submitted to the State Clearinghouse for review by state agencies, and to responsible and trustee
agencies with jurisdiction by law over resources affected by the Project. The Draft IS/MND was made
available for public review at www.laquintaca.gov/111 corridor.
CEQA Guidelines Section 15074(b) states that prior to approving a Project, the Lead Agency must
consider the proposed IS/MND together with any comments received during the public review
process. Written responses to comments are not required; however, the City of La Quinta, as Lead
Agency, has prepared a written response to the comments received for consideration by the Planning
Commission and/or City Council. At the end of the 30-day public review period, a total of four
comments were received. The table below identifies a number for each comment letter received, the
author of the comment letter, and the date received.

and each separate issue raised by the commenter, if more than one, has been assigned a number.
The responses to each comment identify first the number of the comment letter, and then the number
assigned to each issue (Response 1-1, for example, indicates that the response is for the first issue
raised in Comment Letter 1). Responses are provided in this IS/MND as a matter of public disclosure
and transparency.
Based on the evaluation in the IS/MND, the City of La Quinta, as Lead Agency, has determined that
all potential environmental impacts associated with the Project are less than significant with
incorporation of identified mitigation measures. A Mitigation Monitoring Program has also been
prepared and will be implemented for the Project. Therefore, the City of La Quinta has determined
that a Mitigated Negative Declaration in accordance with CEQA is the appropriate environmental
document for the Project.

The Riverside County Flood Control and Water Conservation District (District) does not normally recommend
conditions for land divisions or other land use cases in incorporated cities. The District also does not plan check
City land use cases or provide State Division of Real Estate letters or other flood hazard reports for such cases.
District comments/recommendations for such cases are normally limited to items of specific interest to the
District including District Master Drainage Plan facilities, other regional flood control and drainage facilities
which could be considered a logical component or extension of a master plan system, and District Area Drainage
Plan fees (development mitigation fees). In addition, information of a general nature is provided.
The District's review is based on the above -referenced project transmittal, received May 19, 2025. The District
has not reviewed the proposed project in detail, and the following comments do not in any way constitute or
imply District approval or endorsement of the proposed project with respect to flood hazard, public health and
safety, or any other such issue:
❑X This project would not be impacted by District Master Drainage Plan facilities, nor are other facilities
of regional interest proposed. The project is located within Coachella Valley Water District's (CVWD)
jurisdiction. CVWD is the responsible agency to review and comment on regional flood control
drainage systems within their jurisdictional limits.
❑ This project involves District proposed Master Drainage Plan facilities, namely, The
District will accept ownership of such facilities on written request by the City. The Project Applicant
shall enter into a cooperative agreement establishing the terms and conditions of inspection, operation,
and maintenance with the District and any other maintenance partners. Facilities must be constructed
to District standards, and District plan check and inspection will be required for District acceptance.
Plan check, inspection, and administrative fees will be required. All regulatory permits (and all
documents pertaining thereto, e.g., Habitat Mitigation and Monitoring Plans, Conservation
Plans/Easements) that are to be secured by the Applicant for both facility construction and maintenance
shall be submitted to the District for review. The regulatory permits' terms and conditions shall be
approved by the District prior to improvement plan approval, map recordation, or finalization of the
regulatory permits. There shall be no unreasonable constraint upon the District's ability to operate and
maintain the flood control facility(ies) to protect public health and safety.
❑ This project proposes channels, storm drains larger than 36 inches in diameter, or other facilities that
could be considered regional in nature and/or a logical extension a District's facility, the District would

❑ The Districts previous comments are still valid.
GENERAL INFORMATION
The project proponent shall bear the responsibility for complying with all applicable mitigation measures defined
in the California Environmental Quality Act (CEQA) document, and/or Mitigation Monitoring and Reporting
Program, and with all other federal, state, and local environmental rules and regulations that may apply, such as,
but not limited to, the Multiple Species Habitat Conservation Plan (MSHCP), Sections 404 and 401 of the Clean
Water Act, California Fish and Game Code Section 1602, and the Porter Cologne Water Quality Control Act.
The District's action associated with the subject project triggers evaluation by the District with respect to the
applicant's compliance with federal, state, and local environmental laws. For this project, the Lead Agency is
the agency in the address above, and the District is a Responsible Agency under CEQA. The District, as a Co-
permittee under the MSHCP, needs to demonstrate that all District related activities, including the actions
identified above, are consistent with the MSHCP. This is typically achieved through determinations from the
CEQA Lead Agency (if they are also a Co-permittee) for the project. For the MSHCP, the District's focus will
be particular to Sections 6.1.2, 6.1.3, 6.1.4, 6.3.2, 7.3.7, 7.5.3, and Appendix C of the MSHCP. Please include
consistency determination statements from the Lead Agency/Co-permittee for the project for each of these
sections in the CEQA document. The District may also require that an applicant provide supporting technical
documentation for environmental clearance.
This project may require a National Pollutant Discharge Elimination System (NPDES) permit from the State
Water Resources Control Board. Clearance for grading, recordation, or other final approval should not be given
until the City has determined that the project has been granted a permit or is shown to be exempt.
If this project involves a Federal Emergency Management Agency (FEMA) mapped floodplain, then the City
should require the applicant to provide all studies, calculations, plans, and other information required to meet
FEMA requirements, and should further require that the applicant obtain a Conditional Letter of Map Revision
(CLOMR) prior to grading, recordation, or other final approval of the project and a Letter of Map Revision
(LOMR) prior to occupancy.

Response to Comment Letter #1, Riverside County Flood Control and Water Conservation
District, May 23, 2025
Comment 1-1: The City appreciates the Riverside County Flood Control and Water Conservation
District's (District) comments and the information provided regarding the proposed project. The City
agrees with the District's assessment that the proposed development outlined in the IS/MND for the
Highway 111 Corridor Specific Plan would not be impacted by District Master Drainage Plan facilities
and does not propose facilities of regional interest.
The City acknowledges that the project is located within the jurisdiction of the Coachella Valley Water
District (CVWD), which is the appropriate agency to review and provide input on regional flood control
and drainage systems. The City, along with any future development within the Specific Plan area, will
coordinate with CVWD, as appropriate, to ensure consistency with applicable flood control and
drainage requirements.
Comment 1-2: The City appreciates the District's detailed comments and guidance regarding
regulatory compliance. Through this IS/MND, the City advises that future projects and development
within the Specific Plan area refer to and follow the applicable mitigation measures, as well as comply
with all relevant federal, state, and local environmental regulations identified in the comment.
Future development within the Specific Plan area, as outlined in this IS/MND, will be required to meet
the applicable requirements of the District and the Coachella Valley Multiple Species Conservation
Plan (CVMSHCP). The City understands that future development may also be required to provide
consistency determinations to demonstrate compliance with the provisions of the CVMSHCP. In
addition, supporting technical documentation or supplemental environmental studies may be required
to satisfy environmental clearance requirements. The Biological Resources section of the IS/MND
addresses the Coachella Valley MSHCP, identifies potentially occurring covered species, and
outlines relevant conservation measures.
Additionally, the City recognizes that any future development in the Specific Plan area may require
permits such as NPDES or FEMA-related documentation and will ensure those requirements are
addressed prior to project approvals.

Councilwoman Fitzpatrick,
Thank you for your reply. The plan clearly calls for not just increased density but increased
vertical density, which is the very definition of urban. To throw some street trees into the mix is
like putting lipstick on a pig. Indeed, the levels of density that this plan and the code changes
would allow for are unlike anything presently along Highway 111 and are entirely out -of -character
for La Quinta if not the desert as a whole. To replace empty parking lots with an 'El Paseo' or an
'Old Town' type low density 2-story commercial development would be one thing, but that is not
what is contained in this plan.
As for the affordable housing elements of the plan, La Quinta is only required to meet the
requirements of the RHNA by not standing in the way of affordable housing --no less and no
more. The RHNA certainly does not require the city to purchase land to build public housing on a
mass scale; it seems the only way that things have gotten this far is that the city started this
process in 2022 during the Covid years when residents' attention was focused elsewhere.
As for mass transit, I have personally experienced the supposed benefits of such where my
neighbors and I have been forced to repeatedly call the city to complain about shopping carts
ditched at Sunline bus stops, and for homeless individuals making their way from the commercial
corridor who decide to camp in them. There is zero question that this plan to fundamentally alter
the 111 corridor would exacerbate these kinds of issues in the neighborhoods of North La Quinta.
I assure you that as word gets out, you will find more and more residents contacting council about
this attempt to turn La Quinta into Los Angeles.
Sincerely,
Justin Marlles

Justin,
Your letter will become part of the public record but I just wanted to acknowledge it
and encourage you to look more closely at the plan during the coming presentations.
The plan, I believe, takes into account existing conditions that could be greatly
improved to be LESS urban, less paving for parking, more landscape and better
circulation, tying the areas of north La Quinta to those areas south of 111.
Yes, it does call for additional housing but it is incumbent on the city to help in the
development of more "work force" housing. That housing needs to be where public
transportation exists. Again, not arguing your point just expressing another way to
look at the whole picture while we review the plans.

Mayor Evans, Members of Council, and Ms. Flores:
After reviewing La Quinta's Highway 111 Corridor Specific Plan as well as the draft
Highway 111 Development Code along with the city's Notice of Intent and draft
Mitigated Negative Declaration, it's now plain that the city leadership has lost touch
with its own residents.
Nobody wants an "urban" La Quinta. Indeed, to the contrary, many of us left cities
such as Los Angeles and San Diego to escape dense urban environments and
everything that comes with it. Yet, in what is plainly the result of some city planner's
fever dream, the entire purpose of the Highway 111 Corridor Specific Plan and the
proposed Highway Highway 111 Development Code is to create a newly dense and
"urban" La Quinta complete with hundreds of low income housing units which
presumably will be built on city land.
As a resident of North La Quinta who lives just down Adams Street from this
proposed new urban La Quinta, I assure you that nobody here wants to see our
small city disfigured with numerous 6 story tall buildings (CSP pgs. 27 and 34), high
density city -owned public housing (CSP pgs. 33, 43), or massive mixed -use
developments (CSP pgs. 27, 42, 49, and DG pgs. 5, 15-19) more suitable for LA -or
perhaps Orange County where you hired your engineering team- than La
Quinta. Indeed, it seems the engineering company that authored this totally
unsuitable plan is happy to feather its nest by offering an expensive "on -call
architect/urban designer" who can help destroy La Quinta (CSP pg. 116).
Comment
2-1 (cont.)
It is likewise absurd for the city to claim, as it does in its Notice of Intent to Adopt a
Mitigated Negative Declaration, that this plan "will not have a significant effect on the
environment" or that adequate mitigating measures have somehow been included.
Increasing density in such a severe manner is not only like to lead to stresses on
limited regional water supplies, but could also result in significant traffic issues
throughout the Highway 111 corridor such that emissions will be increased rather
than decreased. As a result, a full Environmental Impact Review would appear more
appropriate and the city's failure to conduct one is of significant concern. This
communication, on which Ms. Cheri Flores has been included, stands as a written
comment from the public in opposition to the project that has been submitted within
the public review period.
The residents of La Quinta are not going to sit by and let city planners with delusions
of grandeur accompanied by out-of-town engineering company destroy the character
of our city. Highway 111 may need a facelift but turning La Quinta into LA isn't it.
You must reject this ill-considered and unsuitable plan.
Respectfully,
Justin Marlles

Response to Comment Letter #2, Justin Marlles, June 6, 2025
Comment 2-1: The Highway 111 Corridor Specific Plan is a long-range planning tool meant to guide
future development that supports La Quinta's evolving needs while preserving its unique character. It
does not call for immediate or large-scale densification, nor does it propose city -built high-rises.
Instead, it supports gradual, infill development to create more diverse and attainable housing options.
Public improvements, like better streetscapes, pedestrian and bike access, and open spaces, often
rely on a stronger residential and business base to be economically viable. A more balanced mix of
uses helps support local businesses and community investment.
The Specific Plan is a flexible guide, not a fixed blueprint. It reflects community input and sets a
framework for thoughtful, context sensitive growth.
The IS/MND was prepared in accordance with CEQA guidelines and supported by technical
analyses. Regarding traffic and utilities, the IS/MND includes analysis based on current data and
regional planning forecasts, confirming that infrastructure and resource capacity can support the
proposed development in line with the City's General Plan.

Subject: RE: The Urbanization Project is a Mistake!
Dear Mayor Evans and City Counsel Members,
I have been a supporter of your campaign for the bulk of your tenure, and I implore you to take a very
careful look at this new Urbanization Project —which will destroy the heart of La Quinta to the
detriment of loyal nearby residents.
After my teams' review of the "Highway 111 Corridor Specific Plan;' the draft "Highway 111
Development Code;' and the associated environmental notices, it is with great concern that I am
writing to express my strenuous opposition to this project. The vision of an "urban" La Quinta, as
detailed in these documents, is a fundamental betrayal of the city's character and the beautiful
nature surrounding it.
La Quinta is a culturally rich city with a view and atmosphere that is unrivaled in many parts of the
world. It is a honeymoon resort town, and many of us chose to make La Quinta our home to escape
the crux of what this project intends to bring and create. The proposal seeks to erect six -story
buildings in an area surrounded by beautiful mountain scenery, and wishes to introduce high -
density housing, and communities for the impoverished. While all this is fine and well in the right
place, La Quinta is not it. This is a radical departure from the suburban, resort -style community we
love and cherish deeply. The notion that this will not have a significant negative impact on our
property values is, frankly, also unbelievable. The unique character of our city is a primary driver of
its desirability; eroding that character will inevitably lead to a decline in property values for those of
us who invested in a different vision for La Quinta.
Furthermore, the plan completely disregards the impact it will have on our already strained
infrastructure. It is a known fact, reported in the news as recently as this past February, that La
Quinta's electrical substations are at or near capacity. [Emphasis Added]. Building a large and
exceptionally dense project of homes with shops will only result in further fracturing of our fragile
power grid and water supply.
Comment

Comment
3-3
In July of 2024 alone, over 1,000 homes in the La Quinta and Indio area experienced power outages
because there was not a stable power supply during the hot summer months. Our valley reached
record highs for multiple days and even hit 126 degrees on some days as a regular occurrence. This
power outage number also does not reflect the planned power outages by the electrical company
used to conserve resources and maintain the grid. In the summer of 2022, the valley had various
"Conserve Alerts" for both electricity and water use.
The Imperial Irrigation District has not been shy about admitting they are underfunded and needing
more infrastructure. IID even backed away from cost -sharing solutions for necessary upgrades. To
add hundreds of new residential units and significant commercial development to this already
fragile system is very irresponsible and invites more frequent and prolonged power outages, while
further stressing our water supply for existing residents.
The assertion in the Mitigated Negative Declaration that this project will not have a significant effect
on the environment is simply not credible, and frankly laughable. A project of this magnitude, with
its focus on dramatically increasing density, will undoubtedly lead to increased traffic congestion, a
greater strain on our precious water resources, heightened crime, and a decline in our quality of life.
A full Environmental Impact Report is not only warranted but essential to fully understand the
detrimental consequences of this plan. I simply cannot support this measure. It will ruin our town
and appears to be nothing more than a deeply concerning money grab for the contractors and
those involved. While I appreciate the heart for progress, this is not the right kind of progress for La
Quinta.
This correspondence serves as a formal public comment in opposition to the "Highway 111
Corridor Specific Plan." We, the residents of La Quinta, will not stand idly by while our city is
transformed into a pale imitation of the urban centers many of us left behind. Highway 111 may
need revitalization, but this ill-conceived and unwanted urbanization is not the answer.
We implore you to listen to your constituents and reject this plan.
Thank you,
Gregory Gruszecki

Response to Comment Letter #3, Gregory Gurszecki, June 9, 2025
Comment 3-1: The City appreciates this comment and acknowledges concerns about the potential
impact of the Highway 111 Corridor Specific Plan on La Quinta's character.
To clarify, the Specific Plan does not significantly increase development intensity beyond what was
established under the City's 2016 zoning overlays. Rather, it provides updated guidance for future
development that aligns with patterns already emerging in surrounding communities in the Coachella
Valley.
The Specific Plan will not increase building height limits and will maintain a 50-foot (4-story) cap in the
proposed Highway Mixed Use Zone. Since 2016, the City's Mixed Use Overlay has allowed similar or
greater heights, and base zoning has long permitted 2- to 4-story buildings in parts of the Specific
Plan area. This ensures future development remains consistent with La Quinta's existing character.
While the Plan allows for greater density than what currently exists — such as big -box stores and large
surface parking lots — it does not significantly alter the City's development pattern. A shift in the land
use mix, informed by real estate market analyses, prioritizes housing over retail, resulting in denser
building types like stacked flats and rowhouses. These may have more bulk than older low-rise retail
and office buildings but still conform to the established height limits.
The Specific Plan also supports the public realm improvements frequently mentioned by the
community — such as signage, lighting, landscaped parkways, pedestrian amenities, and plazas or
patios near new retail. These improvements often depend on infill development to be economically
feasible. Increasing the availability of housing, including more affordable and diverse options, helps
create the residential base needed to support local businesses and justify investments in the public
realm. A Specific Plan that ties these improvements to anticipated development helps make them
more achievable.
While the Specific Plan outlines potential building heights and long-term development capacity, full
build -out across the entire corridor is not expected. The Specific Plan also improves planning
flexibility over time rather than represent guaranteed or immediate changes.
Comment 3-2: The City acknowledges concerns regarding infrastructure capacity, including
electrical and water systems. The Specific Plan references publicly available information and planning
guidance from the Imperial Irrigation District (IID) and Coachella Valley Water District (CVWD), and is
designed to align with the scope and scale of development outlined in the City's General Plan. The
General Plan, which underwent its own environmental review, provides the long-range framework for
growth and infrastructure planning.
It is important to note that future development under the Specific Plan will be subject to additional
project -level review to confirm that adequate utility infrastructure is available prior to construction.
While IID has acknowledged regional infrastructure challenges, it continues to implement phased
improvements and long-term planning efforts to meet growing demand. Additionally, all new
development must comply with current State energy efficiency and water conservation standards,
which help reduce overall resource use compared to older buildings.
The Specific Plan includes policies to support infrastructure planning and long-term sustainability. The
level of growth proposed is consistent with regional forecasts, and the City will continue working with
utility providers to ensure services are maintained and upgraded as needed.
Comment 3-3: The IS/MND thoroughly evaluates potential environmental impacts associated with
the development and implementation of the Specific Plan, including traffic, water resources, public
safety, and community character. Where impacts were identified as potentially significant, the IS/MND
includes mitigation measures for future development projects to reference to reduce these effects to
less -than -significant levels, consistent with CEQA requirements.
It is important to note that this Specific Plan itself does not constitute or approve any development;
rather, it serves as a guidance document to help shape future growth as the City evolves. All
individual development projects proposed under the Specific Plan will be reviewed against CEQA
requirements as applications are received.,.
Regarding traffic and utilities, the IS/MND includes analyses based on current data and regional
planning forecasts to confirm that infrastructure capacity and resource availability can support the
proposed development, consistent with the City's General Plan. The Specific Plan focuses on
enhancing the Highway 111 Corridor by improving the community's overall aesthetic and promoting
safe, walkable neighborhoods. It plans for items including pedestrian and bicycle lanes, pocket parks,
and open spaces for public gatherings, while creating opportunities for local businesses to grow.
Additionally, the Specific Plan offers diverse potential housing options with a variety of configurations,
supporting residents who live and work within the City.
CEQA sets clear guidelines for when an EIR is needed, based on evidence of significant impacts. In
this case, the City determined that the IS/MND with mitigation is appropriate and sufficient.
The City remains committed to a transparent planning process for the Specific Plan and encourages
continued public participation to ensure all community voices are heard.

Historic Overview
J
t%
La Quinta is nestled amidst the Santa Rosa Mountains and is situated on the base of the CV. Achieving
City status on May 1, 1982, La Quinta has witnessed continuous development, particularly along the
Highway 111 Corridor, fueled by a steadily increasir�q population that peaks during the winter season (City
of La Quinta, 2024b). La Quinta is also home to thel'�riginal settlers of th�,area, the Desert Cahuilla Indians.
The Cahuilla people have inhabited the Martinez Canyon area of the CInce the early 1800s and lived
near an area known today as Point Happy. Th Desert Cahuilla Indians were hunter and gatherers and one
of the few Native American Tribes to dig wellNoint Happy held significant importance for the Cahuilla
people due to its role as a 'tal access point to water sources. [ llotably, within a distance of less than 300
yards from Point Happy, a dell was excavated, serving as a pivotal resource for the community. This well
later lent its name to the present-day City of Indian Wells (City of La Quinta, 2024b; SCTCA, 2024).
For centuries, the Cahuilla people were the sole inhabitants of the CV, maintaining a permanent presence.
It wasn't until the early 19th century that Europeans started journeying through the valley. Spanish, and
later Mexican explorers, soldiers, and missionaries arrived with the sole aim of swiftly crossing the
challenging desert terrain (La Quinta Historical Society, 2017).
Record Search
This analysis is based on a cultural records investigation conducted at the California Historical Resources
Inventory System (CHRIS) Eastern Information Center (EIC) located at the University of California,
Riverside. The examination of records took place on January 22, 2024, encompassing a review of maps,
records, and reports from the EIC pertaining to the Project area. The assessment involved a review of the
U.S. Geological Survey (USGS) 1959 La Quinta 7.5 minute series quadrangle map, 1941 Toro Peak 15
minutes series, and 1959 Palm Desert 15 minute series topographic map to assess the Project site. In
addition, the California Points of Historical Interest, California Historical Landmarks, California Register of
Historic Places, National Register of Historic Places (NRHP), the California State Historic Resources
Inventory, and historic topographic maps were reviewed.
The findings revealed that there have been 92 studies on cultural resources conducted within the
approximately 410 acres of the proposed Project area. A total of 56 cultural resource properties are
documented within the Project area boundaries. According to the NRHP, there are no listed properties
located within the bounds of the Project area. Per results from the California Office of Historic

Environmental Analysis — Cultural Resources
Cultural Resources Mitigation Measures
Implementation of mitigation measures CRA through CR-9 would reduce potential impacts to a less -than -
significant level during future construction activities. Appropriate pre -construction training and a data
recovery plan (if needed) would be implemented to address potential discovery of unanticipated
archaeological resources and to preserve and/or record those resources consistent with appropriate laws
and requirements. Proposed mitigation measures for future development are outlined below.
• CR-1: Workers Environmental Awareness Program
A qualified archaeologist who meets or exceeds the Secretary of Interior's Professional Qualification
Standards for archaeology (NPS, 1983) shall conduct Workers Environmental Awareness Program
(WEAP) training on archaeological sensitivity for all construction personnel prior to the
commencement of any ground -disturbing activities. Archaeological sensitivity training shall include a
description of the types of cultural material that may be encountered, cultural sensitivity issues, the
regulatory environment, and the proper protocol for treatment of the materials in the event of a find.
The WEAP training document shall include materials that convey the information noted above,
which shall be maintained in an area accessible to all construction personnel so that it may be
reviewed regularly by construction staff.
• CR-2: Pre -Excavation Agreement
Prior to the issuance of Grading Permits, the Applicant/Owner shall enter into a pre -excavation
agreement, otherwise knovW as a Tribal Cultural Resources Tre tment and Tribal Monitoring
Agreement with consulting Wative American Monitor associated 14ith local tribes. A copy of the
agreement shall be included in building and development plans and permit applications with the
City. The purpose of this agreement,§hall be to formalize prot cols and procedures between the
Applicant/Owner and the consultingl4ative American Monitor Ussociated with local tribes for the
protection and treatment of, including but not limited to, Native American human remains, funerary
objects, cultural and religious landscapes, ceremonial items, and traditional gathering areas and
tribal cultural resources located and/or discovered through a monitoring program in conjunction with
the construction of the proposed project, including additional archaeological surveys and/or studies,
excavations, geotechnical ipvestigations, grading, and all other ground disturbing activities. At the
discretion of the consulting %tive American Monitor, artifacts may be made available for 3D
scanning/printing, with scanned/printed materials to be curated at a local repository meeting the
federal standards of 36CFR79.
• CR-3: Retention of Qualified Archaeologist and Ulative American Monitor
Prior to the issuance of a Grading Permits, the Applicant/Owner or Grading Congctor shall provide
executed contracts or agreements with a Qualified Archaeologist and consultinggative American
Monitor, at the Applicant/Owner or Grading Contractor's expense, to implement the monitoring
program, as described in the pre -excavation agreement.
• CR-4: Tribal Cultural Monitor Coordination During Ground Disturbing Activities
Fl
The Qualified Archaeologist and consultinggative American Monitor shall attend all applicable pre -
construction meetings with the General Contractor and/or associated subcontra5ors to present the
archaeological monitoring program. The Qualified Archaeologist and consulting 9 ative American
Monitor shall be present on -site full-time during grubbing, grading, and/or other ground altering
activities, including the placement of imported fill materials or fill used from other areas of the Project

shall be absent of any and all tribal cultural resources.
• CR-5: Controlled Grade Procedure
To detect important archaeological artifacts and cultural resources during monitoring, a "Controlled
Grade Procedure" [qust be created by a Qualified Archaeologist. This will be done in consultation
with the consulting4-0ative American Monitor, relevant consulting Tribes, and the Applicant/Owner,
and needs approval from City representatives. The procedure will set guidelines for machinery work
in sensitive areas identified during cultural resource monitoring. It will cover aspects like operating
speed, removal increments, weight, and equipment features. A copy of this procedure must be
included in the Grading Plan submissions for Grading Permits.
• CR-6: Discovery of Tribal Cultural Resources
Fi
The Qualif d Archaeologistur consulting dative American Monitor can stop ground -disturbing
activities if9nknown tribal cultural resources or ifacts are foV5E

vicinity of any archaeological discovery until theUrchaeologistn assess its significance and
potential eligibility for the (�qlifornia Register of Historical Resources (CRHR). If buried cultural
deposits are encountered, LAe monitor may request that construction halt nearby and must notify a
qualified archaeologist within 24 hours for investigation.
Fi
Work will be redirected away from these areas for assessment. Winor finds laill be documented and
secured for later repatriation; if items cannot be securely stored on -site, they may be stored off -site.
If the discovered resources are deemed potentially significant, the involved Tribes will be notified for
consultation on their respectful treatment. Avoidance of significant resources is preferred, but if not
feasible, a data recovery plan may be required. The consulting Tribes will be consulted on this plan
as well.
Ur resources under a data recovery n, a proper sample will be collected using professional
methods, reflecting tribal values. The 11 tive American Monitor must be present durin ny resource 1z

may do so and ensure they are treated respectfully according to tribal traditions. Ground -disturb
work will not resume until the resources are documented and/or protected.
• CR-7: Treatment of Tribal Cultural Resources
15 e landowner shall relinquish or hip of all tribal cultural resourc _ 14 rthed during the cultural
resource mitigation monitor �ucted during all ground disturbing�L"tivities, and from any
previous archaeological stuor excavations on the Project site to the affiliated consulting Tribe,
as determined through the appropriate process, for respectful and dignified treatment and
disposition, including reburial at a protected location on -site, in accordance with the Tribe's cultural
and spiritual traditions. All cultural materials that are associated with burial and/or funerary goods
would be repatriated to the Most Likely Descendant as determined by the NAHC per California
Public Resources Code Section 5097.98. No tribal cultural resources shall be subject to curation.
• CR-8: Tribal Cultural Monitoring Report
A monitoring report and/or evaluation report, if appropriate, which describes the results, analysis,

Highway 111 Corridor Specific Plan and Development Code Project (PROJECT)
Mitigated Negative Declaration (MND)
SCH# 2025050964
Dear Cheri Flores:
The California Department of Fish and Wildlife (CDFW) received a Notice of Intent to
Adopt a Mitigated Negative Declaration from the City of La Quinta (City) for the Project
pursuant to the California Environmental Quality Act (CEQA) and CEQA Guidelines.'
Thank you for the opportunity to provide comments and recommendations regarding
those activities involved in the Project that may affect California fish and wildlife.
Likewise, we appreciate the opportunity to provide comments regarding those aspects
of the Project that CDFW, by law, may be required to carry out or approve through the
exercise of its own regulatory authority under the Fish and Game Code.
CDFW ROLE
CDFW is California's Trustee Agency for fish and wildlife resources and holds those
resources in trust by statute for all the people of the State. (Fish & G. Code, §§ 711.7,
subd. (a) & 1802; Pub. Resources Code, § 21070; CEQA Guidelines § 15386, subd.
(a).) CDFW, in its trustee capacity, has jurisdiction over the conservation, protection,
and management of fish, wildlife, native plants, and habitat necessary for biologically
sustainable populations of those species. (Id., § 1802.) Similarly, for purposes of
CEQA, CDFW is charged by law to provide, as available, biological expertise during
public agency environmental review efforts, focusing specifically on Projects and related
'CEQA is codified in the California Public Resources Code in section 21000 et seq. The "CEQA
Guidelines" are found in Title 14 of the California Code of Regulations, commencing with section 15000.

activities that have the potential to adversely affect fish and wildlife resources.
CDFW is also submitting comments as a Responsible Agency under CEQA. (Pub.
Resources Code, § 21069; CEQA Guidelines, § 15381.) CDFW expects that it may
need to exercise regulatory authority as provided by the Fish and Game Code. As
proposed, for example, the Project may be subject to CDFW's lake and streambed
alteration regulatory authority. (Fish & G. Code, § 1600 et seq.) Likewise, to the extent
implementation of the Project as proposed may result in "take" as defined by State law
of any species protected under the California Endangered Species Act (CESA) (Fish &
G. Code, § 2050 et seq.), the Project proponent may seek related take authorization as
provided by the Fish and Game Code.

Objective: The Project proposes the development of a Highway 111 Corridor Specific
Plan and Highway 111 Development Code. The Highway 111 Corridor (Corridor)
consists of a roughly two-mile stretch of businesses located along the La Quinta portion
of Highway 111, between Washington and Jefferson Streets. The Highway 111
Development Code is a land use policy that establishes development standards for the
Corridor's expansion, incorporating location -specific guidelines like active frontage, and
offering detailed information on qualifying uses, as well as additional requirements and
permissions for future growth. The MND has been prepared in accordance with CEQA
to provide a programmatic -level review of potential environmental impacts associated
with the proposed Highway 111 Corridor Specific Plan and provides guidance for
implementing development within the Project area.
Economically feasible buildout under the Specific Plan could result in the following
additional square footages (sf):
• Residential: 1,464,000 to 1,837,000 sf
• Retail: 107,000 to 194,000 sf
• Office: 82,000 sf
• Hotel: 150,000 to 250,000 sf
The proposed Highway 111 Corridor Specific Plan would enable proposed future
projects to consider this impact analysis when evaluating their potential environmental
impacts. As a programmatic -level document, however, this CEQA analysis is not
anticipated to provide sufficient detail to fully address the project -specific impacts of all
future development. It is anticipated that additional environmental technical studies or
CEQA documentation may be needed for future projects. It is anticipated that CEQA
compliance for future projects would be tiered from this document.

Location: The Project is located along Highway 111 within the City of La Quinta,
California, in the County of Riverside. The Project encompasses two miles along
Highway 111 between Washington Street on the west, Jefferson Street on the east, the
Whitewater Wash on the north, and Avenue 48 on the south. The Project area is just
over approximately 410 acres (-0.64 square miles).
Timeframe: The MND proposes build -out of projects over the course of 20 to 25 years.
COMMENTS AND RECOMMENDATIONS
CDFW has jurisdiction over the conservation, protection, and management of fish,
wildlife, native plants, and habitat necessary for biologically sustainable populations of
those species (i.e., biological resources). CDFW offers the comments and
recommendations below to assist the City in adequately identifying and/or mitigating the
Project's significant, or potentially significant, direct and indirect impacts on fish and
wildlife (biological) resources. The MND has not adequately identified and disclosed the
Project's impacts (i.e., direct, indirect, and cumulative) on biological resources and
whether those impacts are reduced to less than significant.
CDFW's comments and recommendations on the MND are explained in greater detail
below and summarized here. CDFW is concerned that the MND does not adequately
identify or mitigate the Project's significant, or potentially significant, impacts to
biological resources. CDFW requests that additional information and analyses be added
to a revised MND, along with avoidance, minimization, and mitigation measures that
avoid or reduce impacts to a level less than significant.
Comment
5-1 1 Existing Environmental Setting
Compliance with CEQA is predicated on a complete and accurate description of the
environmental setting that may be affected by the proposed Project. CDFW is
concerned that the assessment of the existing environmental setting has not been
adequately analyzed in the MND. CDFW is concerned that without a complete and
accurate description of the existing environmental setting, the MND may provide an
incomplete analysis of Project -related environmental impacts.
The MND lacks a complete and appropriate assessment of biological resources within
the Project site and surrounding area specifically as it relates special -status species
(see Assessment of Biological Resources Section), burrowing owl (Athene cunicularia),
and the Lake and Streambed Alteration Program. A complete and accurate assessment
of the environmental setting and Project -related impacts to biological resources is
needed to both identify appropriate avoidance, minimization, and mitigation measures
and demonstrate that these measures reduce Project impacts to less than significant.

CEQA requires that an MND include mitigation measures to avoid or reduce significant
impacts. CDFW is concerned that the mitigation measures proposed in the MND are not
adequate to avoid or reduce impacts to biological resources to below a level of
significance. To support the City in ensuring that Project impacts to biological resources
are reduced to less than significant, CDFW recommends revising the mitigation
measure for burrowing owl, nesting birds, and artificial nighttime lighting, and adding
mitigation measures for an assessment of biological resources and, as it relates to a the
Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP), the local
development mitigation fee and salvage of sand -dependent covered species.
1) Assessment of Biological Resources
Page 1-2 of the MND states that the "proposed Highway 111 Corridor Specific Plan
would enable proposed future projects to consider this impact analysis when evaluating
their potential environmental impacts. Where sufficiently addressed herein, future
development may be considered `within the scope' of this environmental analysis. As a
programmatic -level document, however, this CEQA analysis is not anticipated to
provide sufficient detail to fully address the project -specific impacts of all future
development. Indeed, it is anticipated that additional environmental technical studies or
CEQA documentation may be needed for future projects once sufficient details are
known. In such cases, the necessary environmental studies and documentation may be
conducted at the time of proposal. It is anticipated that CEQA compliance for future
projects would be tiered from this document." CDFW is concerned about the adequacy
of analysis in this MND to establish baseline conditions for biological resources, identify
impacts to biological resources, and determine appropriate avoidance, minimization and
mitigation measures for development projects covered in this MND. For example, page
3 of the Technical Memorandum, dated May 8, 2023 (Special -Status Species Report),
for the MND did not include any protocol -level surveys for special -status wildlife. Also,
note that CDFW generally considers biological field assessments for wildlife to be valid
for a one-year period, and assessments for rare plants may be considered valid for a
period of up to three years. Given the uncertainty in timelines for the implementation of
the various projects covered in this MND (over a period of 20-25 years per page 3-89 of
the MND)—and the ability for biological resources to change during intervening
periods—CDFW recommends that additional assessments of biological resources,
including, but not limited to, focused surveys for special -status species that have the
potential to occur on these project sites, are conducted and the results circulated to the
public in subsequent CEQA documentation to establish environmental baselines, inform
avoidance, minimization, and mitigation measures, and allow CDFW to conduct a
meaningful review and provide appropriate biological expertise.
To ensure impacts to biological resources associated with the projects covered in this
MND are adequately assessed and reduced to a level less than significant, CDFW
recommends the following mitigation measure is added to a revised MND:

Prior to Project construction activities for all projects covered in this MND, a
complete and recent inventory of rare, threatened, endangered, and other
sensitive species located within the Project footprint and within offsite areas with
the potential to be affected, including California Species of Special Concern
(CSSC) and California Fully Protected Species (Fish and Game Code § 3511), will
be completed. Species to be addressed should include all those which meet the
CEQA definition (CEQA Guidelines § 15380). The inventory should address
seasonal variations in use of the Project area and should not be limited to
resident species. Focused species -specific surveys, completed by a qualified
biologist and conducted at the appropriate time of year and time of day when the
sensitive species are active or otherwise identifiable are required. Acceptable
species -specific survey procedures should be developed in consultation with
CDFW and the U.S. Fish and Wildlife Service, where necessary. Note that CDFW
generally considers biological field assessments for wildlife to be valid for a one-
year period, and assessments for rare plants may be considered valid for a period
of up to three years. Some aspects of the proposed Project may warrant periodic
updated surveys for certain sensitive taxa, particularly if the Project is proposed
to occur over a protracted time frame, or in phases, or if surveys are completed
during periods of drought.
Pursuant to the CEQA Guidelines, section 15097(f), CDFW has prepared a draft
mitigation monitoring and reporting program (MMRP) in Attachment 1 for recommended
revisions to MM BIO-3, MM BIO-4, MM BIO-5 and CDFW-recommended MM BIO-[A],
MM BIO-[B], and MM BIO-[C].
Nesting Birds
It is the Project proponent's responsibility to comply with all applicable laws related to
nesting birds and birds of prey. Fish and Game Code sections 3503, 3503.5, and 3513
afford protective measures as follows: section 3503 states that it is unlawful to take,
possess, or needlessly destroy the nest or eggs of any bird, except as otherwise
provided by Fish and Game Code or any regulation made pursuant thereto. Fish and
Game Code section 3503.5 makes it unlawful to take, possess, or destroy any birds in
the orders Falconiformes or Strigiformes (birds -of -prey) or to take, possess, or destroy
the nest or eggs of any such bird except as otherwise provided by Fish and Game Code
or any regulation adopted pursuant thereto. Fish and Game Code section 3513 makes it
unlawful to take or possess any migratory nongame bird except as provided by rules
and regulations adopted by the Secretary of the Interior under provisions of the
Migratory Bird Treaty Act of 1918, as amended (16 U.S.C. § 703 et seq.).
With regard to the CVMSHCP, per its associated Implementing Agreement (IA) and
Permits from CDFW and the U.S. Fish and Wildlife Service (the Wildlife Agencies),
Take associated with Covered Activities will not be in violation of the Migratory Bird
Treaty Act and will be consistent with Fish and Game Code sections 3503 and 3503.5-1
therefore, all Covered Activities within and outside Conservation Areas must undertake

measures to avoid the take of individuals, nests, and eggs of nesting birds. The
CVMSHCP includes a general conservation measure that applies to all bird species to
avoid impacts to habitat for nesting birds during the nesting season (CVMSHCP Section
9.7). Per IA Section 13.2, the City is obligated to ensure the projects to which it confers
Take Authorization under the CVMSHCP comply with all terms and requirements of the
CVMSHCP, the Wildlife Agencies' Permits that create the CVMSHCP, and the IA,
including compliance with laws that protect nesting birds.
Pages 3-16 of the MND indicates that "the entire Project area may support migratory
and nesting birds." CDFW concurs that all the project locations covered in this MND
contain habitat for nesting birds due to the presences of shrubs on the undeveloped
vacant parcels and presence of landscaping trees and shrubs in the developed parcels.
Although the MND includes Mitigation Measure BIO-3 for nesting birds, CDFW
considers the measure inadequate in scope to reduce impacts to nesting birds to a level
less than significant. For example, CDFW considers proposed buffer distances for
burrowing owls, 160 feet during the non -breeding season and 250 feet during the
breeding season, to be inadequate. (See Burrowing Owl Section below for a burrowing
owl -specific measure recommended by CDFW.)
To support the City in reducing impacts to nesting birds to a level less than significant
Comment for all projects covered in the MND, CDFW recommends that the City revise Mitigation
5-3 (cont.) Measure BIO-3 with the following additions in bold and removals in strike+hreu h:
Mitigation Measure 131O-3: Nesting Birds
Regardless of the time of year, nesting bird surveys shall be performed by a
qualified avian biologist no more than 3 days prior to all vegetation removal or
ground -disturbing activities for all projects covered in this MND. Pre -construction
surveys shall focus on both direct and indirect evidence of nesting, including
nest locations and nesting behavior. The qualified avian biologist will make every
effort to avoid potential nest predation as a result of survey and monitoring
efforts. If active nests are found during the pre -construction nesting bird surveys,
a qualified biologist shall establish an appropriate nest buffer to be marked on
the ground. Nest buffers are species specific and shall be at least 300 feet for
passerines and 500 feet for raptors. A smaller or larger buffer may be determined
by the qualified biologist familiar with the nesting phenology of the nesting
species and based on nest and buffer monitoring results. Construction activities
may not occur inside the established buffers, which shall remain on -site until a
qualified biologist determines the young have fledged or the nest is no longer
active. Active nests and adequacy of the established buffer distance shall be
monitored daily by the qualified biologist until the qualified biologist has
determined the young have fledged or the Project has been completed. The
qualified biologist has the authority to stop work if nesting pairs exhibit signs of
disturbance. potential ❑rOjeGt imnaGts to siv snorial status birds and rnmmen hiriJs

2) Burrowing Owl
On October 10, 2024, the Fish and Game Commission determined that western
burrowing owl warrants protection as a candidate species under the California
Endangered Species Act (Fish & G. Code, § 2050 et seq.). During the candidacy period,
western burrowing owl will be afforded the same protection as threatened and
endangered species under CESA. If Project activities, including relocation, could result
in take, appropriate CESA authorization (i.e., Incidental Take Permit under Fish and
Game Code section 2081) should be obtained prior to commencement of Project
activities.
Take of individual burrowing owls and their nests or eggs is defined by Fish and Game
Code section 86, and prohibited by sections 3503, 3503.5, and 3513. Take is defined in
Fish and Game Code section 86 as "hunt, pursue, catch, capture or kill, or attempt to
hunt, pursue, catch, capture or kill." Fish and Game Code sections 3503, 3503.5, and
3513 afford protective measures as follows: section 3503 states that it is unlawful to
take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise
provided by Fish and Game Code or any regulation made pursuant thereto. Fish and
Game Code section 3503.5 makes it unlawful to take, possess, or destroy any birds in
the orders Falconiformes or Strigiformes (birds -of -prey) or to take, possess, or destroy
the nest or eggs of any such bird except as otherwise provided by Fish and Game Code
or any regulation adopted pursuant thereto. Fish and Game Code section 3513 makes it
unlawful to take or possess any migratory nongame bird except as provided by rules
and regulations adopted by the Secretary of the Interior under provisions of the
Migratory Bird Treaty Act of 1918, as amended (16 U.S.C. § 703 et seq.).
With regard to the CVMSHCP, the CDFW Natural Community Conservation Plan
(NCCP) Permit #2835-2008-001-06 does not provide Take Authorization for burrowing
owl individuals, nests, or eggs. To the contrary, section 3.5.6 of the NCCP Permit states
burrowing owl "pairs or individuals will not be Taken" and reiterates that the
"HCP/NCCP does not authorize Take of [burrowing owl] nests [or] eggs[.]" Therefore,
throughout the CVMSHCP area —both within and without Conservation Areas—
Permittees must ensure that activities occurring within their jurisdictions do not result in

the take, possession, or destruction of burrowing owl individuals, nests, or eggs. Any
activity occurring within the CVMSHCP area that results in the take of burrowing owl
individuals, nests, or eggs would be unlawful and would not be a Covered Activity under
the CVMSHCP. Per IA Section 13.2, the City is obligated to ensure the projects to which
it confers Take Authorization under the CVMSHCP comply with all terms and
requirements of the CVMSHCP, the Wildlife Agencies' Permits that create the
CVMSHCP, and the IA, including compliance with laws that protect burrowing owls.
Page 1-2 of the MND states that "as a programmatic -level document, however, this
CEQA analysis is not anticipated to provide sufficient detail to fully address the project -
specific impacts of all future development. Indeed, it is anticipated that additional
environmental technical studies or CEQA documentation may be needed for future
projects once sufficient details are known." CDFW agrees that a project -specific
analysis of impacts to burrowing owl, which is needed to inform project -specific
avoidance, minimization, and mitigation measures, is necessary for each of the projects
covered in the MND that contain suitable habitat for burrowing owl. Page 19 of the
Project's Special -Status Species Report indicates that burrowing owl have a moderate
potential to occur for projects covered in the MND. CDFW agrees that the project areas
that contain vacant land, including but not limited to potential development areas ADN-
01, DJN-1, DJS-1, WAS-01, and ADS-2 have suitable habitat for burrowing owl. Also,
potential development areas ADN-01, DJN-1, WAN-02, and WAN-01 are located
adjacent to the Whitewater River, which provides suitable habitat for burrowing owl.
Page 19 of the Special -Status Species Report states that the "nearest records on the
CNDDB are approximately three miles away, and are from 1927 to 2007 (CDFW 2022)."
CDFW adds that unprocessed data from the California Natural Diversity Database
include three recent observations, between 2021 and 2023, of burrowing owl using
burrows within 0.25 miles of Project site to the east in a channel associated with the
Whitewater River. Page 3 of the Biological Report indicates that a reconnaissance field
survey was conducted on February 4, 2023, and that "no protocol -level surveys for
wetlands, SNCs, special status plants, or wildlife were conducted." A habitat
assessment and focused surveys for burrowing owls have not been conducted for the
projects covered in this MND. Given the MND's lack of findings from a habitat
assessment and recent focused surveys for burrowing owl following the guidelines in
the Staff Report on Burrowing Owl Mitigation, the number and locations of suitable and
occupied burrows within the project areas covered in this MND are unknown. Given the
lack of results from a habitat assessment and focused surveys following recommended
protocols and the lack of survey reports, CDFW is limited in its ability to provide
biological expertise to support the City in reducing impacts to burrowing owl to a level
less than significant for the projects covered in this MND. CDFW recommends a habitat
assessment and focused surveys for burrowing owl are conducted for all of the projects
covered in this MND and that the survey results, including survey reports, are provided
in subsequent CEQA environmental review documents for the public and CDFW to
review.

The MND includes a general Mitigation Measure BIO-4 to be applied across projects
covered in the MND. CDFW finds Mitigation Measure B1O4 to be insufficient in scope
and timing to reduce impacts to burrowing owl to a level less than significant. For
example, Mitigation Measure BIO-4 indicates that burrowing owl relocation may be
implemented by the Project (page 3-20). Burrowing owl relocation is considered a
potentially significant impact under CEQA and should only be considered as a last
resort, after all other options have been evaluated. Burrowing owl relocation (i.e.,
eviction/passive and active relocation) can result in take of burrowing owl individuals,
nests, and eggs, which is not authorized under the CVMSHCP. Consultation with
CDFW is warranted to determine if an Incidental Take Permit is necessary to avoid a
violation of Fish and Game code section 2080.
CDFW recommends that the City revise general Mitigation Measure 131O-4 with the
following additions in bold and removals in strikethr,,y :
Mitigation Measure BIO-4: Burrowing Owl Habitat Assessment and Focused and
Pre -Construction Surveys
No less than 60 days prior to the start of Project -related activities for all projects
covered in the MND, a burrowing owl habitat assessment shall be conducted by a
qualified biologist according to the specifications of the Staff Report on
Burrowing Owl Mitigation (Department of Fish and Game, March 2012 or most
recent version) for all projects covered under the MND.
If the habitat assessment demonstrates suitable burrowing owl habitat, then
focused burrowing owl surveys shall be conducted by a qualified biologist in
accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most
recent version) prior to vegetation removal or ground -disturbing activities. If
burrowing owls are detected during the focused surveys, the qualified biologist
and Project proponent shall begin coordination with CDFW and USFWS
immediately, and shall prepare a Burrowing Owl Avoidance and Monitoring Plan
that shall be submitted to CDFW for review and approval prior to commencing
Project activities. The Burrowing Owl Plan shall describe proposed avoidance
and monitoring actions, including measures necessary to avoid take of burrowing
owl individuals, nests, and eggs. The Burrowing Owl Plan shall include the
number and location of occupied burrow sites (occupied site means at least one
burrowing owl or its sign has been observed within the last three years; may be
indicated by owl sign including feathers, pellets, prey remains, eggshell
fragments, or excrement at or near a burrow entrance or perch site), acres of
burrowing owl habitat that will be impacted, details of site monitoring, and details
on proposed buffers and other avoidance measures. If impacts to occupied
burrowing owl habitat or burrow(s) or burrowing owl individuals, nests, or eggs
cannot be avoided, appropriate CESA authorization (i.e., Incidental Take Permit

under Fish and Game Code section 2081) should be obtained from CDFW prior to
commencement of Project activities.
Preconstruction burrowing owl surveys shall be conducted no less than 14 days
prior to the start of Project -related activities and within 24 hours prior to ground
disturbance, in accordance with the Staff Report on Burrowing Owl Mitigation
(2012 or most recent version). Preconstruction surveys should be repeated when
there is a pause in construction of more than 30 days. Preconstruction surveys
should be performed by a qualified biologist following the recommendations and
guidelines provided in the Staff Report on Burrowing Owl Mitigation. If the
preconstruction surveys confirm occupied burrowing owl habitat, Project
activities shall be immediately halted. The qualified biologist shall coordinate with
CDFW and prepare a Burrowing Owl Avoidance and Monitoring Plan that shall be
submitted to CDFW and USFWS for review and approval prior to commencing

Page 12
Fish and Game Code section 1602 requires any person, state or local governmental
agency, or public utility to notify CDFW prior to beginning any activity that may do one
or more of the following: divert or obstruct the natural flow of any river, stream, or lake;
change the bed, channel, or bank of any river, stream, or lake; use material from any
river, stream, or lake; or deposit or dispose of material into any river, stream, or lake.
Note that "any river, stream, or lake" includes those that are episodic (i.e., those that a
dry for periods of time) as well as those that are perennial (i.e., those that flow year-
round). This includes ephemeral streams, desert washes, and watercourses with a
subsurface flow.
The MND is a programmatic -level document, and it is anticipated that additional
environmental technical studies or CEQA documentation may be needed for future
projects associated with this MND once sufficient details are known (page 1-2 of the
MND). Four of the projects covered in this MND are located adjacent to the Whitewater
River, including potential development areas WAN-01, WAN-02, ADN-01, and DJN-1.
Page 4 of the Biological Assessment indicates that the "Project does not involve
alteration of the Whitewater River, including the channel and floodplain. There will be no
impact to the Whitewater River or jurisdictional wetlands." CDFW is concerned about
the validity of this conclusion that projects adjacent to the Whitewater River will have not
impacts on fish and wildlife resources subject to Fish and Game Code section 1600 et
seq. CDFW notes that the MND lacks details on design plans for projects covered in the
MND, and that project -specific design plans are needed to inform if projects will result in
impacts on fish and wildlife resources subject to Fish and Game Code section 1600 et
seq. The MND includes Mitigation Measure BIO-6, indicating that "prior to construction
and issuance of any grading permit, the Project Sponsor shall obtain written
correspondence from CDFW stating that notification under Section 1602 of the Fish and
Game Code is not required for the Project, or the Project Sponsor should obtain a
CDFW-executed Lake and Streambed Alteration Agreement, authorizing impacts to
Fish and Game Code Section 1602 resources associated with the Project." Importantly,
CDFW notes that the MND does not provide information on the projects for which this
measure would apply. CDFW recommends that the MND is revised to indicate that for
all projects covered in this MND, subsequent CEQA documentation will include a
project -specific analysis of potential impacts to fish and wildlife resources subject to
Fish and Game Code section 1600 et seq. to inform if a notification of lake or streambed
alteration needs to be submitted to CDFW.
4) Coachella Valley Multiple Species Habitat Conservation Plan
Local Development Mitigation Fee
The Project is located within the CVMSHCP Plan Boundary and outside of a
Conservation Area and contains habitat for Covered Species and/or conserved natural
communities. Page 3-16 of the MND states that the "according to the CVMSHCP,
authorization of take for all species with a moderate potential to occur, except the six
bird species, can be obtained through compliance with the CVMSHCP and the Local

Development Mitigation Fee (LDMF) paid to the Coachella Valley Conservation
Commission". Per CVMSHCP Section 5.2.1.1 and IA Sections 12.2.1 and 13.2, the City
is obligated to impose a local development mitigation fee for new development within
the Plan Area that impacts vacant land containing Habitat for Covered Species and/or
conserved natural communities, including small vacant lots within urban areas that
contain natural open space, and to transmit collected fees to CVCC at least quarterly
and prior to impacts to Covered Species and their Habitats. To document the City's
obligation to impose and transmit a Local Development Mitigation Fee for projects
covered in this MND, CDFW recommends the City add the following mitigation measure
to a revised MND:
Mitigation Measure BIO-[B]: CVMSHCP Local Development Mitigation Fee
Prior to construction and issuance of any grading permit for all projects covered
in the MND, the City shall ensure compliance with the Coachella Valley Multiple
Species Habitat Conservation Plan (CVMSHCP) and its associated Implementing
Agreement and shall ensure the collection of payment of the CVMSHCP Local
Development Mitigation Fee and transfer of fees, at least quarterly and prior to
impacts to Covered Species and their Habitats, to the Coachella Valley
Conservation Commission.
Comment
5-6 (cont.) I Salvage of Sand -Dependent Covered Species
Section 6.6.1 of the CVMSHCP (Obligations of Local Permittees) states that within and
outside Conservation Areas "on parcels approved for Development, the Permittees shall
encourage the opportunity to salvage Covered sand -dependent species in accordance
with the Implementation Manual." Page 3-18 of the MND indicates that "Wildlife species
covered by the CVMSHCP that have a moderate potential to occur include Palm
Springs Round -tailed Ground Squirrel [(Xerospermophilus tereticaudus chlorus)],
Burrowing Owl, Flat -tailed Horned Lizard [(Phrynosoma mcallii)], Coachella Valley
Fringe -tailed Lizard [(Uta inornata)], and the Coachella Giant Sand Treader Cricket
[(Macrobaenetes valgum)]." The Project areas including potential development area
DJS-1 contain CVMSHCP modeled habitat for Coachella Valley fringe -toed lizard. To bE
consistent with CVMSHCP requirements, CDFW recommends that the City include in a
revised MND the following mitigation measure:
Mitigation Measure BIO-[C]: Salvage of Sand -Dependent Covered Species
Prior to vegetation removal or ground -disturbing activities, for all project areas
covered in the MND that contain suitable habitat for sand -dependent Covered
Species, the City will collaborate with the Coachella Valley Conservation
Commission to plan and implement a salvage of sand -dependent Covered
Species within the Project site.
5) Artificial Nighttime Lighting

Page 14
Several of the projects associated with this MND are located adjacent to the Whitewater
River, an area that provides suitable burrowing, nesting, roosting, foraging, and refugia
habitat for birds, migratory birds that fly at night, and other nocturnal and crepuscular
wildlife. Artificial lighting alters ecological processes including, but not limited to, the
temporal niches of species; the repair and recovery of physiological function; the
measurement of time through interference with the detection of circadian and lunar and
seasonal cycles; the detection of resources and natural enemies; and navigation.2 Many
species use photoperiod cues for communication (e.g., bird song3), determining when to
begin foraging,4 behavioral thermoregulation,5 and migration.6 Phototaxis, a
phenomenon that results in attraction and movement towards light, can disorient,
entrap, and temporarily blind wildlife species that experience it.10
Page 3-3 of the MND indicates that "future development facilitated by the Specific Plan
may include low -impact lighting fixtures and reflective surfaces that are designed to
reduce brightness, which would enhance visual comfort and safety without contributing
to light pollution." The MND includes Mitigation Measure 131O-5, requiring that "during
Project construction and operation, the City shall eliminate all nonessential lighting
throughout the Project area and avoid or limit the use of artificial light during the hours
of dawn and dusk when many wildlife species are most active. The City shall ensure
that lighting for Project activities is shielded, cast downward, and does not spill over
onto the properties or upward into the night sky following International Dark -Sky
Association standards." The MND lacks information on project(s) to which this mitigation
measure would apply. CDFW recommends the City revise Mitigation Measure 131O-5
with the following additions in bold and removals in strikethro unh:
Mitigation Measure BIO-5: Artificial Nighttime Lighting
Throughout construction and the lifetime operations of all projects covered in the
MND, the City and Project proponents shall eliminate all nonessential lighting
throughout the Project area and avoid or limit the use of artificial light at night
during the hours of dawn and dusk when many wildlife species are most active.
The City and Project proponent shall ensure that all lighting for the Project is fully
shielded, cast downward and directed away from surrounding open -space and
agricultural areas, reduced in intensity to the greatest extent possible, and does
not result in lighting trespass including glare into surrounding areas or upward

ENVIRONMENTAL DATA
CEQA requires that information developed in environmental impact reports and
negative declarations be incorporated into a database which may be used to make
subsequent or supplemental environmental determinations. (Pub. Resources Code, §
21003, subd. (e).) Accordingly, please report any special -status species and natural
communities detected during Project surveys to the California Natural Diversity
Database (CNDDB). The CNNDB field survey form can be filled out and submitted
online at the following link: https://wildlife.ca.gov/Data/CNDDB/Submitting-Data. The
types of information reported to CNDDB can be found at the following link:
https://www.wildlife.ca.gov/Data/CNDDB/Plants-and-Animals.
ENVIRONMENTAL DOCUMENT FILING FEES
The Project, as proposed, would have an impact on fish and/or wildlife, and assessment
of environmental document filing fees is necessary. Fees are payable upon filing of the
Notice of Determination by the Lead Agency and serve to help defray the cost of
environmental review by CDFW. Payment of the environmental document filing fee is
required in order for the underlying Project approval to be operative, vested, and final.
(Cal. Code Regs, tit. 14, § 753.5; Fish & G. Code, § 711.4; Pub. Resources Code, §
21089.)
CONCLUSION
CDFW appreciates the opportunity to comment on the MND to assist the City in
identifying and mitigating Project impacts to biological resources. CDFW concludes that
the MND does not adequately identify or mitigate the Project's significant, or potentially
significant, impacts to biological resources. CDFW recommends that revised and
additional mitigation measures and analysis as described in this letter be added to a
revised MND.
CDFW personnel are available for consultation regarding biological resources and
strategies to avoid and minimize impacts. Questions regarding this letter or further

Response to Comment Letter #5, California Department of Fish and Wildlife, June 23, 2025
Comment 5-1: The City appreciates the California Department of Fish and Wildlife's (CDFW)
comments and recommendations on the Draft IS/MND and shares CDFW's commitment to the
conservation and protection of biological resources.
As a planning -level environmental document, the IS/MND is intended to guide future development
within the Specific Plan area. It is supported by a biological technical report based on field
investigations and a review of habitat types, species occurrences, and the likelihood of special -status
species within the Specific Plan boundaries. The document identifies potential biological impacts at a
programmatic level and recommends mitigation measures that future development can reference.
Less than one-third of the Specific Plan area housing units will be on undeveloped land, further
focusing growth within already disturbed or developed areas. The IS/MND has been revised to
incorporate CDFW's suggested avoidance, minimization, and mitigation measures, which will help
inform and guide project -level environmental review. The City agrees that future development
projects should conduct project -specific biological resource assessments to further evaluate potential
impacts and develop site -specific measures that avoid or minimize effects on sensitive species and
habitats.
By incorporating CDFW's recommendations, the IS/MND provides a framework to ensure future
development remains consistent with CEQA and avoids or reduces biological impacts to less -than -
significant levels.
Comment 5-2: The City understands and appreciates CDFW's concerns regarding the adequacy of
the biological resources analysis and the importance of maintaining current, site -specific data to
support CEQA review.
The IS/MND is intended to provide a planning -level understanding of biological resources and habitat
conditions within the Specific Plan area. It draws upon field investigations and a biological technical
study to inform the analysis and offer a framework to guide future development. However, we
recognize that development will occur incrementally over the next 20-25 years, and site conditions
may change over time.
To address this, the IS/MND has incorporated the recommended mitigation measure related to the
Assessment of Biological Resources into the IS/MND to help ensure future projects establish
accurate environmental baselines and adequately address potential impacts to biological resources.
Comment 5-3: The City appreciates CDFW's detailed comments and recommendations regarding
protections for nesting birds and compliance with the Migratory Bird Treaty Act and California Fish
and Game Code sections. We understand and appreciate CDFW's concerns and agree that
protecting nesting birds and their habitat is essential.
In response, the City has revised Mitigation Measure BIO-3 to incorporate CDFW's recommended
additions, including updated buffer distances and avoidance measures. These revisions strengthen
the mitigation and better ensure that impacts to nesting birds are reduced to less than significant
levels.
Comment 5-4: Thank you for your comments regarding protections for the western burrowing owl
under California Endangered Species Act (CESA), the Fish and Game Code, and the CVMSHCP.
The City understands that burrowing owl is now a candidate species under CESA and must be fully
protected during the candidacy period and recognizes that take of individuals, nests, or eggs is not
authorized under the CVMSHCP and that any relocation or other activity resulting in take would
require consultation with CDFW and potentially an Incidental Take Permit under Fish and Game
Code Section 2081.
In response to CDFW's comments, the City has revised Mitigation Measure BIO-4 to incorporate
CDFW's recommended measures. These include requiring a habitat assessment and focused
surveys for future development following the Staff Report on Burrowing Owl Mitigation, applying
appropriate avoidance buffers, and ensuring relocation is only considered as a last resort and in
coordination with CDFW.
Comment 5-5: The City agrees and understands that all future development within the Specific Plan
area must evaluate potential impacts to the Whitewater River, particularly for sites adjacent to the
river, including WAN-01, WAN-02, ADN-01, and DJN-01. Mitigation Measure BIO-6 emphasizes that
future projects should consult with CDFW to determine if a Lake and Streambed Alteration
Agreement is necessary.
Comment 5-6: This comment is noted. The City recognizes the significance of adhering to the
requirements of the CVMSHCP and ensuring compliance. This includes obligations related to the
Local Development Mitigation Fee and the salvage of sand -dependent Covered Species where
applicable. The City has adopted Ordinance No. 487 (Chapter 3.34 of the La Quinta Municipal Code)
regarding the collection of the LDMF and does collect the LDMF at building permit issuance. The City
has revised Mitigation Measure 131O-7 to incorporate the suggested language provided by CDFW
regarding both the Local Development Mitigation Fee and salvage of sand -dependent species. This
will ensure that future development projects covered under the IS/MND remain consistent with the
CVMSHCP.
Comment 5-7: The City appreciates CDFW's detailed comments regarding the potential impacts of
artificial lighting on wildlife habitat adjacent to the Whitewater River. The City understands the
importance of minimizing light pollution to protect nocturnal and crepuscular species and their
ecological processes.
The IS/MND is consistent with the City's lighting standards as outlined in the Municipal Code and the
General Plan, which emphasize responsible lighting practices that reduce impacts on wildlife and
preserve night sky quality. In response to your recommendations, the City has revised Mitigation
Measure BIO-6 to strengthen the requirements for shielding, directing, and minimizing lighting
impacts.
These revisions will ensure that future development within the Specific Plan area follows best
practices for nighttime lighting to protect sensitive species and habitats near the Whitewater River.

The California Department of Transportation (Caltrans) Local Development Review (LDR) Branch
has completed its review of the Mitigated Negative Declaration (MND) for the Highway 1 1 1
Corridor Specific Plan and Development Code. This review involved a thorough evaluation of
the proposed project's potential impacts on the state transportation system, including
considerations related to traffic operations, safety, and compliance with applicable state
regulations. Caltrans' assessment ensures that necessary mitigation measures are identified to
minimize any adverse effects on regional mobility and public safety as the Specific Plan
advances toward implementation.
The City of La Quinta is developing a Highway 1 1 1 Corridor Specific Plan and Development
Code to transform a key two-mile retail corridor —responsible for 75% of the City's sales tax —into
a vibrant, mixed -use area. The plan promotes integrated commercial, residential, and
recreational development, supported by improved infrastructure and transportation access,
including Highway 1 1 1 and the Coachella Valley Link. The Development Code provides
location -specific standards and land use guidelines. Replacing previous plans, this initiative aligns
with the City's General Plan and aims to enhance connectivity, encourage economic growth,
and improve overall quality of life.
We applaud the City of La Quinta for taking proactive and forward -thinking steps to support
multimodal and transit -oriented development. By prioritizing integrated transportation options
and mixed -use planning, the City is fostering a more accessible, sustainable, and vibrant
community. These efforts not only enhance mobility and reduce reliance on single -occupancy
vehicles but also promote economic vitality, improve public health, and contribute to a higher
quality of life for residents and visitors alike.

Public Transit - We encourage the City of La Quinta to continue its strong coordination with
SunLine Transit Agency to ensure the Highway 1 1 1 Corridor remains accessible and well-
connected via public transit. Ongoing collaboration will be essential to developing a truly
multimodal transportation network that supports current and future transit needs, reduces
traffic congestion, and enhances mobility for all users, including residents, workers, and
visitors.
Future Developments - We encourage the City of La Quinta to continue supporting future
mixed -use and high -density residential development within and around the Specific Plan
area. Such efforts are key to reducing VMT and advancing more sustainable, efficient land
use patterns that align with regional housing and climate goals.
Bicycle Connectivity - We encourage the City of La Quinta to strengthen connections
between the Specific Plan area and the existing bike lane network to promote active
transportation. Enhancing bicycle infrastructure will support increased ridership among
employees and visitors, reduce vehicle dependency, and contribute to a more sustainable
and accessible community.
Bike Parking and End -of -Trip Facilities - To support and encourage bicycle commuting, the
project should incorporate secure bike parking —such as racks and lockers —at key
destinations throughout the Specific Plan area. Additionally, providing end -of -trip amenities
like showers and changing facilities at workplaces will further promote cycling as a practical
and convenient mode of transportation.
VMT Mitigation Measures - Property owners, building owners, and tenants are encouraged to
implement VMT reduction measures the maximum extent feasible, in order to support
sustainability goals and reduce VMT.

Section 2.0 - Project Description (PDF pp. 19-30) - The Project Description highlights Highway
1 1 1 as a "major arterial corridor," promoting walkability and multimodal improvements.
However, no details are provided on how access modifications or development impacts to
SR-1 11, especially at key intersections like Jefferson and Washington Streets, will be managed.
It is recommended that the MND specify whether access or signal timing will be modified and
clarify whether this would require Caltrans coordination.
Section 3.17 - Transportation (PDF pp. 154-160); Appendix G - The MND claims VMT
reductions due to mixed -use development but fails to quantify VMT or compare against
regional significance thresholds, as required under SB 743. A quantified VMT analysis using

Appendix G - Cumulative Impacts (Section 21) - Although cumulative impacts are dismissed,
the Plan increases urban density and potentially impacts SHS operations. The MND should
acknowledge and coordinate with SCAG's Connect SoCal RTP/SCS, CVAG's CV Link
Implementation Plan, and Caltrans' DSMP for SR-1 1 1 to assess growth impacts more
comprehensively.
tquitall Access
If any Caltrans facilities are impacted by the project, they must comply with American Disabilities
Act (ADA) Standards upon project completion. Additionally, the project must ensure the
maintenance of bicycle and pedestrian access throughout the construction phase. These
access considerations align with Caltrans' equity mission to provide a safe, sustainable, and
uitable transportation network for all users.

Response to Comment Letter #6, Caltrans, June 23, 2025
Comment 6-1: The City appreciates Caltrans' comments and support for the Highway 111 Corridor
Specific Plan and its goals to advance sustainable, multimodal, and transit -oriented development.
Ongoing coordination with SunLine Transit Agency remains a priority to ensure continued connectivity
and accessibility. The Specific Plan emphasizes mixed -use and high -density development, enhanced
bicycle infrastructure, and active transportation options to support sustainability, housing, and climate
goals. The City also supports incorporating secure bike parking, end -of -trip facilities, and feasible
VMT reduction measures to reduce vehicle dependency and promote more sustainable travel
choices.
Comment 6-2: The Specific Plan will have no impact on the State Highway System. Although the
roadway is still referred to as "SR 111" in La Quinta, it is no longer part of the State Highway System,
having been relinquished to the City in 2008. The continued use of the "SR 111" designation is due to
an agreement between the County of Riverside and the Cities of Cathedral City, Coachella, Indian
Wells, Indio, La Quinta, and Palm Desert to maintain the signage for consistency and driver
orientation along the original alignment. The nearest segment of SR 111 that remains part of the
State Highway System is located in Cathedral City, approximately 13 miles away — well beyond the
area where the Specific Plan would have any influence on traffic operations.
As this is a planning -level document, specific access or signal modifications are not yet determined.
Under CEQA Guidelines Section 15064.3(b)(4), the selection of VMT thresholds and methodologies
is at the discretion of the lead agency. The City has carefully considered its approach and determined
that the use of a qualitative analysis is appropriate for this planning -level document.
It is important to note that the project area is located within a low VMT area — defined as generating
less than 85% of the regional jurisdictional baseline — based on the Riverside County VMT model
(see: Riverside VMT Model Webmap). In addition, land use forecasting shows that anticipated
development in the corridor will generate less traffic than what is currently assumed in the City's
General Plan.
The City appreciates Caltrans' recommendations but maintains that the methodology used in the
IS/MND is consistent with CEQA and appropriate for this stage of planning. Additionally, the City
acknowledges Caltrans' suggestion to incorporate measurable multimodal performance standards
and references such as the Smart Mobility Framework, Level of Traffic Stress (LTS) indicators, and
Complete Streets design guidance. This feedback is noted for consideration in future planning and
project -level design efforts.
The City recognizes the suggestion to address freight circulation and potential conflicts with
pedestrians along SR-111. While this planning -level document does not include a detailed freight
analysis, the recommendation is noted for future project -level planning and design.
While the Specific Plan proposes increased urban densities, the City sees this as a positive outcome
— consistent with Caltrans' own acknowledgment in Bullet #2 under Local Development Review.
Higher -density, mixed -use development supports reduced VMT and more sustainable, multimodal
travel.
As a planning -level document, the IS/MND evaluates impacts at a programmatic scale. The City
acknowledges the recommendation to reference regional plans and will consider these in future
project -level efforts.
Comment 6-3: The City understands the need to comply with ADA standards for any impacted
Caltrans facilities and to maintain bicycle and pedestrian access during construction. These
considerations will be addressed in future project planning and implementation. We note, however,
that there are no Caltrans facilities in the area affected by the Specific Plan (see response to
Comment 6-2 regarding the relinquishment) and we do not anticipate any effects on Caltrans
facilities.
Comment 6-4: The City acknowledges that any permanent work or temporary traffic control within
Caltrans' right-of-way will require a Caltrans-issued encroachment permit. This requirement will be
advised for future project implementation. We note, however, that there are no Caltrans facilities in
the area affected by the Specific Plan (see response to Comment 6-2 regarding the relinquishment)
and we do not anticipate any encroachment onto Caltrans rights -of -way.
