1. Introduction
The City of La Quinta is proposing an update to the housing element of its general plan. The housing
element is one of the seven general plan elements mandated by the State of California, as articulated in
Sections 65580 to 65589.8 of the Government Code. To comply with state law, La Quinta prepares a housing
element every five years or in conjunction with the release of the Regional Housing Needs Assessment
(RHNA). The La Quinta Housing Element must contain goals, policies, and programs to facilitate the
development, improvement, and preservation of housing. State law prescribes the scope and content of the
housing element pursuant to Section 65583 of the California Government Codes. The element also provides
a comprehensive evaluation of programs and regulations related to priority goals, objectives, and program
actions that directly address the needs of La Quinta residents. The housing element is only one facet of the
City's overall planning program. The California Government Code requires that general plans contain an
integrated, consistent set of goals and policies. The housing element is, therefore, affected by development
policies contained in other elements of the general plan.
The City of La Quints, as lead agency for the project, is responsible for preparing environmental
documentation in accordance with the California Environmental Quality Act (CEQA), as amended, to
determine if approval of the discretionary actions requested could have a significant impact on the
environment. This Initial Study will provide the City of La Quinta with information to document potential ��
impacts of the proposed project.
1.1 PROJECT LOCATION
Figure 1, Regional Location, shows the location of the City of La Quints in the Riverside County region. La
Quinta is one of nine cities in the Coachella Valley subregion of Riverside County. The Coachella Valley
includes the cities of Cathedral City, Coachella, Desert Hot Springs, Indian Wells, Indio, La Quinta, Palm
Desert, Palm Springs, and Rancho Mirage, as well as large areas of unincorporated Riverside County. La
Quinta is bordered by Indian Wells, Palm Desert, Indio, and unincorporated Riverside County. Regional
access is provided by Interstate 10 (I-10) and State Route 86 (SR-86), located outside of La Quinta's
boundary. State Route 111 (SR-111), near the City's northern boundary, is the only state system in the City s
limits.
1.2 ENVIRONMENTAL SETTING
1.2.1 Existing Land Use
The draft housing element pertains only to the area within the incorporated City limits (20,672.6 acres),
excluding the City's sphere of influence area and two planning areas, as shown in the City of La Quinta
General Plan Land Use Map. Based on the 2002 General Plan Land Use Element, 57.4 percent of the land
area is devoted to residential development, 4.9 percent to commercial uses, 1.1 percent to industrial, 0.8
percent to major community facility uses, and 35.8 percent to parks, open space, and golf course open
space.
2008 La Quinta Housing Element Update Initial Study City of La Quinta • Page 1
1. Introduction
1.22 Surrounding Land Use
The City of La Quints is one of nine cities in the Coachella Valley subregion of Riverside County. The cities of
Indian Wells and Palm Desert share the western border with the City and the City of Indio shares the City's
eastern border (see Figures 2 and 3). Most of Indian Wells abutting La Quints, is mountainous and
undeveloped. Uses in Palm Desert and Indio include various residential (rural residential to suburban type
residential uses), recreational, commercial, and industrial, especially along major corridors like the 1-10 and
SR-111. Unincorporated Riverside County bounds much of the City south of Avenue 52, including the Santa
Rosa Mountains to the east. The Bermuda Dunes Airport is in unincorporated Riverside County to the north
of the City and south of 1-10.
1.3 PROJECT DESCRIPTION
The housing element is one of the seven general plan elements mandated by the State of California.
Jurisdictions within the Southern California Association of Governments (SCAG) region must complete the
statutory housing element update for a seven -and -one -half -year planning period that extends from January
1, 2006, through June 30, 2014.
The proposed project is the draft housing element; which contains policy guidance and a list of potential
actions and development project The housing element does not represent actionable proposals for
individual, subsequent housing development projects or required general plan amendments, and/or zone
changes needed to implement the respective projects. This initial study, therefore, is not required to provide
a detailed evaluation of the subsequent projects or provide mitigation for the impacts that may be associated
With implementation of those projects. This Initial study, does, however, provide an overall evaluation of the
Impacts that would likely occur to successfully Implement the proposed housing element. Each individual
development project and zone change required to implementthe housing element will be subject to its own
subsequent review and processing under CEQA.
The housing element of the La Quints. General Plan Identifies vacant and underutilized sites for potential
residential and residential over commercial development that could accommodate any unmet portion of the
RHNA by 2014 and establishes the City's policy relative to the maintenance and development of housing.
The goals, policies, and programs of the housing element will guide housing -related decision making and
facilities attainment of the 2006-2014 RHNA housing targets.
Regional Housing Needs Assessment
SCAG prepares housing construction needs goals for each city in Southern California as part of the RHNA.
As set forth in state law, all local governments are required to identify sufficient land, adopt programs, and
provide funding, to the extent feasible, to facilitate and encourage housing production commensurate with
that need.
As shown in Table 1, the City's total RHNA allocation is 4,327 units for the 2DO6-2014 planning period. The
production goal for each income category Is: 1,065 units affordable to very low Income households, 724
affordable to low income households, 796 affordable to moderate income households, and 1,741 above
moderate income units.

Accommodating the RHNA
California housing element law allows local governments to obtain construction credits toward its RHNA
housing goals in three ways: housing construction, available land for housing, and housing preservation. The
housing element has identified resources through new construction and available vacant or underutilized
land to demonstrate an ability to accommodate the RHNA. It is important to note that, for the purposes of
accommodating the RHNA, the State Department of Housing and Community Development allows
jurisdictions to list the very low and low income categories as one combined income category referred to as
"lower income" or "very low and low income."
Housing Construction
As shown in Table 2, the City has constructed or approved 516 very low income units, 60 low income units,
569 moderate income units, and 4,530 above moderate housing units but still has the allocation balance of
1,440 units (549 very low Income units, 664 lower income units, and 227 moderate income units).

1. Introduction
Development Potential on Vacant and Underutilized Land
To address the remaining RHNA, the City has identified available land for future construction as shown In
Figure 4, Vacant and Underutilized Land Inventory. Vacant land includes vacant residential sites, vacant sites
zoned for nonresidential uses that also allow residential development, and nonresidential vacant sites that
must be rezoned for residential use. As shown in Table 3, the housing element Identifies 110.9 vacant acres
with a total expected yield of 1,165 units at a realistic capacity based on existing development trends. This
unit yield includes 21.4 acres, identified as Site #2 in Figure 4, to be rezoned from RL to RM (residential low
density to residential medium density). The zoning changes, when they do occur, could add additional
housing potential in the amount of approximately 281 units. The current project does not Include the actual
zoning amendment; the rezoning is anticipated to occur concurrent with the City's 2009/2011 general plan
update.
Underutilized sites are nomracant sites that contain stalled or severely underperforming projects, or vacant
sites that have obsolete entitlements or need to be rezoned, and are likely to be available for housing
development during the planning period. The underutilized sites Inventory is made up of 131.6 acres of RM
land (including 16.8 acres to be rezoned from RL), 53.7 acres of RMH (residential medium -high density) land
(Including 19.7 acres to be rezoned from RM to RMH), and 21.6 acres of neighborhood commercial (CN) and
village commercial (VC) land. The total acreage in the underutilized land Inventory Is 206.9, 199.9 acres of
which are already zoned to accommodate residential development at or above 8 units per acre. The total
expected yield of these sites Is 1,651 units at a realistic capacity based on existing development trends and
densities. The zoning changes, when they do occur, could add additional housing potential In the amount of
approximately 203 units.

Summary of Development Potential
Table 4 summarizes the housing and land resources available to the City and demonstrates an ability to
accommodate its RHNA allocation. Table 5 provides a summary of the City's quantified objectives for new
construction and rehabilitation or housing assistancefor La Quinta residents during the planning period. The
City's quantified objectives for new construction do not have to match the RHNA figures; they can be lower
or higher than the RHNA figures. State law only requires that the City demonstrate an ability to potentially
accommodate the RHNA allocation, as shown in Table 4. Moreover, the quantified objectives do not
represent proposals for the new housing projects and thus do not constitute projects under CECI&
The City also maintains or participatesin many other programs that will assist in the rehabilitation and
Improvement of housing in La Quinta that are not listed in Table 5. At this time, these other programs do not
have quantified objectives. For example, it is currently unknown how many La Quints households will utilize
County of Riverside rehabilitation grants or how much money may be available from new state and federal
resources, and there are not any unit targets by income level for housing condition monitoring.
Table 4
K1
' The number of constructed and approved projects represents active projects In the City of La 0ubda that have been constructed after January 1, 2006
or are expected to be constructed during the 2006-2014 planning period. Some of the units restricted to very low Income households may be
Inhabited by households earning 0 to 30 percent of the Area Median Income (AMI), (mown as extremely low income households.
f Assisted projects on vacant and underodlWd lands could also have the potential to provide housing for extremely low income households should 0he
ellillbOhy range Include households earning 0 to 30 percent of the AMI.
3 The affordability of levels of future second unWguest houses Is an estimate based on a rents survey and City pogctes. For example, If all of the units
am guest houses they will be affordable to extremely low Income households, since they mind be provided free of rent, per the Municipal Code.

1.3.1 General Plan Consistency
State law requires that a general plan be internally consistent. Goals, policies, and implementation measures
in the general plan elements must support and be consistent with one another. The City of La Quanta's draft
housing element builds on the other nine elements in the La Quinta General Plan and is consistent with goals
and policies set forth therein. The City will continue to maintain consistency between general plan elements
by ensuring that proposed changes in one element will be reflected in otherelements through amendmentof
the general plan. The City's housing element identifies programs and resources required for the
preservation, improvement, and development of housing to meet the existing and projected needs of Its
population.
1.4 GENERAL PLAN AND ZONING
Figure 5, Existing Zoning Map, shows existing zoning designations within the City of La Quinta. The update to
the City's general plan housing element consists of an updated determination of housing needs in the City,
and revisions to policies and programs the City would implement to address those needs. It identifies
adequate vacant and underutilized sites for potential residential development that could accommodate any
unmet portion of the RHNA by 2014.
Several of the sites identified in the housing element currently have general plan designations and zoning in
place that would facilitate higher density development in the area, and the housing element does not
propose any changes to land use and zoning in that area. In other cases, upzoning and amendments to the
municipal code would take place to accommodate all of the unmet need forthe RHNA. Therefore, concurrent
with the 2009/2011 general plan update, the City would evaluate the feasibility of policy and program
changes to redesignate higher density development and permit residential above nonresidential uses.
Therefore, with the adoption of the 2006-2014 housing element, the City of La Quanta is not redesignating
land or amending zoning that would directly result in the construction of any housing units or accelerate the
rate of development on existing sites that could presently accommodate such development. However,
subsequent implementation of the 2006-2014 housing element would require rezoning that would induce
growth. At that time, the City would conduct environmental review of the impacts associated with that action.
Moreover, any future projects proposed in accordance with the draft housing element would be subject to
CEQA review.
1.5 CI YACTION REQUESTED
Approval of the General Plan housing element and adoption of the Negative Declaration for compliance with
CEQA by the La Quinta City Council.

Mandatory Findings of Significance
2.3 DETERMINATION fro BE COMPLETED BY THE LEAD AGENCI9
On the basis of this initial evaluation:
I find that the proposed project COULD NOT have a significant effect on the environment, and a
NEGATIVE DECLARATION will be prepared.
I find that although the proposed project could have a significant effect on the environment, there will
not be a significant effect in this case because revisions in the project have been made by or agreed to by
the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.
❑ I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
I find thatthe proposed project MAY have a "potentially significant impact" or "potentially significant
unless mitigated" impact on the environment, but at least one effect t) has been adequately analyzed in an
earlier document pursuantto applicable legal standards, and 2) has been addressed by mitigation measures
based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT Is
required, but it must analyze only the effects that remain to be addressed.
F1I find that although the proposed project could have a signficant effect on the environment, because
all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE
DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that
earlier El or NEGATIVE DECLARATION, Including revisions or mitigation measures that are Imposed upon
the proposed project,. nothing further is required:

2. Environmental Checklist
24 EVALUATION OF ENVIRONMENTAL IMPACTS
1) A brief explanation is required for all answers except "No Impact" answers that are adequately
supported by the information sources a lead agency cites in the parentheses following each
question. A "No Impact" answer is adequately supported if the referenced information sources show
that the impact simply does not applyto projects like the one involved (e.g., the project falls outside
a fault rupture zone). A "No Impact" answer should be explained where it is based on project -
specific factors, as well as general standards (e.g., the project would not expose sensitive receptors
to pollutants, based on a project -specific screening analysis).
2) All answers must take account of the whole action involved, including offske as well as onsite,
cumulative as well as project -level, indirect as well as direct, and construction as well as operational
impacts.
3) Once the lead agency has determined that a particular physical impact may occur, the checklist
answers must Indicate whether the impact is potentially significant, less than significant with
mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is
substantial evidence that an effect may be significant. If there are one or more "Potentially Significant
Impact" entries when the determination is made, an EIR is required.
4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the
incorporation of mitigation measures has reduced an effectfrom "PotentiallySignificent impact" to a
"Less Than Significant Impact." The lead agency must describe the mitigation measures, and briefly
explain how they reduce the effect to a less than significant level. emN
5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process,
an effect has been adequately analyzed in an earlier EIR or negative declaration per Section
15063(c) (3) (D) of the CEQA Guidelines. In this case, a brief discussion should Identify the following:
a) Earlier Analyses Used. Identify and state where they are available for review.
b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the
scope of and adequately analyzed in an earlier document pursuant to applicable legal
standards, and state whether such effects were addressed by mitigation measures based on the
earlier analysis.
c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures
Incorporated," describe the mitigation measures which were incorporated or refined from the
earlier document and the extent to which they address site -specific conditions for the project.
6) Lead agencies are encouraged to incorporate into the checklist references to information sources
for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or
outside document should, where appropriate, include a reference to the page or pages where the
statement is substantiated. A source list should be attached, and other sources used or individuals
contacted should be cited in the discussion.
7) Supporting Information Sources: A source list should be attached, and other sources used or
individuals contacted should be cited in the discussion.

8) This is only a suggested form, and lead agencies are free to use different formats; however, lead
agencies should normally address the questions from this checklist that are relevant to a project's
environmental effects In whatever format is selected.
9) The explanation of each issue should identify:
a) the significance criteria or threshold, if any, used to evaluate each question; and
b) the mitigation measure Identified, If any, to reduce the impact to less than significant.

3. Environmental Analysis
Section 2.2 provided a checklist of environmental impacts. This section provides an evaluation of the impact
categories and questions contained in the checklist.
3.1 AESTHETICS
a) Have a substantial adverse effect on a scenic vista?
No Impact. The draft housing element identifies opportunity areas for housing development and strategies
to achieve the regional housing needs production goals. Much of the Coachella Valley subregion has views
of the desert and mountains. Increased residential density allowed by the updated housing element would
after visual qualities in the area and potentially have impact on a scenic vista. The location of properties that
would support densities where buildings would be greater than one story in height are limited to commercial
areas or the Village District —locations that already contain and allow for multistory buildings. However, the
housing element is a policy document and itself would not result in actual construction of housing units.
Therefore, it would not result in the individual or subsequent housing development projects. The proposed
project would not create any significant impacts and no mitigation measures are necessary.
b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and
historic buildings within a state scenic highway?
No Impact. According to the California Scenic Highway Mapping System of the California Department of
Transportation, the City is not located near a major state -designated scenic highway. The nearest officially
designated state scenic highway is State Route 74 near the City of Palm Desert. The proposed updates to
the housing element would not have any substantial damage to scenic resources. No mitigation measures
are necessary.
c) Substantially degrade the existing visual character or quality of the site and Its surroundings?
No Impact. The draft housing element identifies opportunity areas for housing development and strategies
to achieve the regional housing needs production goals. The proposed project is the draft housing element,
not the individual, subsequent housing development projects or required zone changes needed to
implement the respective projects. Therefore, although the existing visual character or quality of the City may
change subsequent to the adoption of the draft housing element, the current project would have no Impact
on the visual character. No mitigation measures are necessary.
d) Create a new source of substantial light or glare, which would adversely affect day or nighttime
views in the area?
No Impact. The draft housing element identifies opportunity areas for housing development and strategies
to achieve the regional housing needs production goals. Development of projects in accordance with the
City's draft housing element would create new sources of light and glare in the City. As potential units are
developed, greater intensity and density of development would result in increased light and glare in the City
due to exterior lighting, lighting of streets and walkways, and interior lighting. The City of La Quints. is in the
boundaries of the Mount Palomar Nighttime Lighting Policy Area and the effect of nighttime lighting on star-
2008 La Quinta Housing Element Update Initial Study City of La Quinta • Page 29
3. Environmental
gazing and open space areas will become more pronounced with additional housing development.
However, it should be noted that the proposed project is the draft housing element, not the individual,
subsequent housing development projects or required zone changes needed to implement the respective
projects. In addition, the City has an Outdoor Light Control Ordinance (Municipal Code Chapter 9.100.150,
Outdoor Lighting) to protect night sky and light impacts on sensitive receptors. Future development or zone
changes to implement the draft housing element would be subject to subsequent CEQA review. No impact is
anticipated and no mitigation measures are necessary.
2.2 AGRICULTURE RESOURCES
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?
Lose Than Significant Impact. According to the Farmland Mapping and Monitoring Program, there are
special status farmlands in the City of La Quints. However, these areas are already zoned residential by the
La Quints Zoning Map. As shown in Figure 6, there are prime farmland, unique farmland, and farmland of
local importance In the City of La Quints, and some of the vacant and underutilized lands identified by the
housing element are designated as special status farmland. Adopting the updated housing element would
allow vacant and underutilized land to be developed with higher density development. However, these lands
are already designated and zoned residential by the general plan and the zoning map. Therefore, adoption
of the updated housing element Itself would not result in conversion of special status farmland to
nonagricultural uses. Impact would be less than significant and no mitigation measures are necessary.
b) Conflict with existing zoning for agricultural use, or a wUllamson Act contract?
No Impact. Adopting the updated housing element would allow vacant and underutilized land to be
developed with higher density development. However, these lands are already designated and zoned
residential by the general plan and the zoning map. The City of La Quinta Zoning Map does not designate
any areas in its planning area as agricultural except for the Low Density Agricultural/Equestrian Residential
zone. However, these areas would not be affected by the draft housing element. In addition, no properties
within the City are impacted by a Williamson Act contract. Conflict with existing agricultural zoning is not
anticipated and no mitigation measures are necessary.
Q Involve other changes in the existing environment which, due to their location or nature, could
result in conversion of Farmland, to non-agricultural use?
Less Than Significant impact. The City of La Quints zoning map does not show any agricultural uses within
the City limits. Although the housing element identifies vacant and underutilized sites to rezone, they are
already zoned for nonagricultural uses. Therefore, zone changes would not result in conversion of farmlands
to agricultural uses. In addition, the housing element itself would not result in the actual development. Future
development projects would be subject to CEQA review and potentially significant impacts to agricultural
resources would be analyzed. Adoption of the housing element would not have a significant Impact on
conversion of farmland. No mitigation measures are necessary.

3,3 AiR QUALiiY
a) Conflict with or obstruct Implementation of the applicable air quality plan?
No Impact. The City of La Quints lies in the Salton Sea Air Basin (SSAB), which spans the Coachella Valley
portion of Riverside County and ail of Imperial County. Air quality management of the Riverside County
portion of the SSAB is overseen by the South Coast Air Quality Management District (SCAQMD). The air
quality plan in effect in the SSAB is the SCAQMD's 2007 Air Quality Management Plan (AQMP). The
SCAQMD and SCAG are the agencies responsible for preparing the AQMP. Regional population, housing,
and employment projections developed by SCAG, which are based on the land use designations of the
City's General Plan form, in part, the foundation for the emissions inventory of the AQMP. These
demographic trends are incorporated Into the Regional Transportation Plan (RTP) compiled by SCAG to
determine priority transportation projects and determine vehicle miles traveled within the SCAG region.
The draft housing element designates adequate sites for development that could potentially accommodate
any unmet portion of the RHNA through 2014. Since the housing assessment in the RHNA is determined by
SCAG, the proposed project would accommodate increases In population based on SCAG s demographic
projections. The project would be consistentwith the AQMP because it Is based on demographic projections
forthe City of La Quints from which SCAQMD creates the regional emissions Inventory. Therefore, no impact
Is anticipated and no mitigation measures are necessary.
b) Violate any air quality standard or contribute substantially to an existing or projected air quality
violation?
Loss Than SlgniBcarrt. The draft housing element designates adequate sites for potential future
development that could accommodate any unmet portion of the RHNA through 2014. New development
could potentially generate pollutant emissions due to new vehicletrips, use of equipment, and oftslte power
and natural gas generation. During the construction phases of individual development projects, emissions
would also be generated by construction vehicles and activities. Air pollutant emissions associated with the
project could occur over the short tens for demolition, site preparation, and construction activities. In
addition, emissions could result from the long-term operation of the potential additional units.
Construction Impacts
Air quality impacts may occur during the site preparation and construction activities of individual projects
anticipated under the draft housing element. Major sources of emissions during this phase Include exhaust
emissions generated during demolition of an existing structure, site preparation, and subsequent structure
erection, and fugitive dust generated as a result of soil disturbances.
To minimize construction -related air quality Impacts, future development projects would be required to
comply with SCAQMD Rules and Regulations, including Rule 403 for fugitive dust control. Chapter 6.16 of
the City of La Quints Municipal Code also requires local dust control plans for projects, which is modeled on
Rule 403 and 403.1. Additionally, any future development projects would be subject to CEQA review and
evaluated for potential constructlon-related air quality impacts.
Operational Impacts
Long-term air quality impacts are those associated with the emissions produced from project -generated
vehicle trips as well as from stationary sources related to the use of natural gas for heating and to electricity
for lighting and ventilation. Any future developments would be subject to CEQA review on a project-by-

project basis, and impacts would be disclosed and mitigated as feasible. However, impactsto any air quality
standard due to the adoption of the housing element would result in a less than significant impact.
Greenhouse Gas Emissions
Assembly Bill 32 (AB 32), the Global Warming Solutions Act, was passed by the California state legislature
on August 31, 2006, to place the state on a course toward reducing its contribution of greenhouse gas
(GHG) emissions. The California Air Resources Board adopted the Proposed Climate Change Scoping Plan
(Scoping Plan) to reduce GHG emissions on a statewide level. Construction and operational phase activities
associated with individual projects that Implement the objectives of the housing plan would directly and
indirectly generate GHG emissions from stationary sources (water heaters, gas stoves, landscape
equipment, etc.), transportation, water use, energy use, and waste disposal. Future development in the City
would be subject to CEQA review on a project -by -project basis, to evaluate the contribution of GHG
emissions and consistency with the Scoping Plan. Impacts of the individual development projects would be
disclosed and mitigated as feasible. However, the cumulative contribution of GHG emissions due to the
adoption of the housing element would result in a less than significant impact.
c) Result Ina cumulatively considerable net Increase of any criteria pollutant for which the project
region is non -attainment under an applicable federal or state ambient air quality standard
(Including releasing emissions which exceed quantitative thresholds for ozone precursors)?
Less Than Significant. The draft housing element designates adequate sites for potential future
development that could accommodate any unmet portion of the RHNA through 2014. New development
would generate pollutant emissions due to new vehicle trips, use of equipment, and ofisite power and natural
gas generation. Future projects would be subject to CEQA review, and computer modeling would be
completed for each development to track whether any emissions would be in excess of state or federal
ambient air quality standards. Additionally, any new development would be required to comply with
SCAQMD regulations to mitigate or preventthe generation of criteria pollutant emissions or GHG emissions.
Impacts to air quality due to the adoption of the housing element would be less than significant.
d) Expose sensitive receptors to substantial pollutant concentrations?
Less Than Significant. Approval of the housing element would not modify land uses and would riot result in
an air quality impact. Implementation of the housing element relies, however, on future development
assumptions. The potential future development of additional housing units through 2014 could lead to
fugitive emissions and other pollutants affecting adjacent sensitive land uses. Increased traffic volumes on
City streets could also lead to Increases in associated vehicle emissions. Air quality analysis would be
completed on a project -by -project basis to determine whether emissions from proposed development would
expose sensitive receptors to substantial pollutant concentrations. Impacts to air quality due to the adoption
of the housing element would be less than significant.
e) Create objectionable odors affecting a substantial number of people?
No Impact. Land uses that are sources of objectionable odors that may affect substantial numbers of people
include wastewater treatment facilities, landfills, refineries, chemical manufacturing facilities, feed lots, and
dairies. Approval of the housing element would not create objectionable odors and would not result in an
impact. Implementation of the housing element is reliant, however, on future development assumptions. Itis
unlikely that any future residential/mixed-use development would create objectionable odors; however, any
project would be subject to CEQA review. Adoption of the housing element would not create odors and no
impact would occur.

M4 BIOLOGICAL RESOURCES
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?
No Impact. The housing element designates adequate sites for potential future housing development to
meet the RHNA allocation. The City of La Quints contains a variety of unique habitat types, including
blowsand habitat, mesquite hummocks, alluvial habitat, desert dry wash, and rocky slopes that potentially
support a wide variety of sensitive plant and animal species, some of which have been listed as threatened
or endangered by federal and state governments. Therefore, future development projects would be subject
to CEQA review and potentially significant Impacts to biological resources would be analyzed. However,
adoption of the housing element itself would have no Impact on any species identified as a candidate,
sensitive, or special status species. No mitigation measures are necessary.
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 U.S. Fish and Wildlife Service?
No Impact. The housing element designates adequate sites for potential future housing development to
meet the RHNA allocation. The City of La Quint& contains a variety of unique habitat types, including
blowsand habitat, mesquite hummocks, alluvial habitat, desert dry wash, and rocky slopes that potentially
support a wide variety of sensitive plant and animal species, some of which have been listed as threatened
or endangered by federal and state governments. Mesquite hummocks are a native plant community that
consists of large clumps of honey mesquite formed over sand dunes or level terrain. Mesquite hummocks 88
are generally associated with high soil moisture or natural springs. However, adoption of the housing
element itself would have no impact on any riparian habitat or other sensible natural community. No
mitigation measures are necessary.
c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the
Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct
removal, filling, hydrological interruption, or other means?
Less Than Significant. There are a number of water bodies in the City: the Whitswater River, La Quinta
Evacuation Channel, and Coachella Canal being the most prominent. The housing element designates
adequate sites for potential future housing development to most the RHNA allocation. it Is unlikely that
housing development would result in direct removal, filling, or hydrological interruption of any federally
protected wetlands. However, future development or subsequent zone changes would be subject to CEQA
review. Adoption of the housing element itselfwould have no adverse impact on federally protected
wetlands. No mitigation measures are necessary.
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?
Less Than Significant. The'City hosts a'wide variety of state and federally protected sensitive plant and
animal species. Future development projects would be subject to CEQA review and potentially significant
impacts to biological resources would be analyzed. However, adoption of the housing element itself would
have no impact on any species identified as a candidate, sensitive, or special status species. No mitigation
measures are necessary.
2008 La Quinta Hooting Element Update Initial Study City of La Quetta • Page 35
3. Environmental Analysis
e) Conflict with any local policies or ordinances protecting biological resources, such as a tree
preservation policy or ordinance?
Less Than Significant. The City hosts a wide variety of state and federally protected sensitive plant and
animal species. Future development projects would be subject to CEQA review and potentially significant
impacts to biological resources would be analyzed. However, adoption of the housing element itself would
have no impact on any species identified as a candidate, sensitive, or special status species. No mitigation
measures are necessary.
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. The City of La Quinta lies within the Multi -Species Habitat Conservation Plan
(MSHCP), which replaced the Coachella Valley Fringe -Toed Uzard Habitat Conservation Plan and the
Peninsular Bighorn Sheep Critical Habitat. Implementation of the draft housing element would require
amendment to the zoning map and the zoning ordinance to accommodate the unmet RHNA allocation.
However, the vacant and underutilized areas identified in the draft housing element are already designated
as residential or commercial uses, and increased development density proposed by the draft housing
element would not convert land designated for natural open space to urban land uses. Additionally, each
development project would be required to comply with the applicable habitat conservation implementation
plan. Impacts would be less than significant and no mitigation measures are necessary.
&S CULTURAL RESOURCES
a) Cause a substantial adverse change In the significance of a historical resource as defined in
§ 15064.5?
Less Than Significant. The draft housing element identifies underutilized and vacant sites for potential
future developmentthat could accommodate any unmet portion of the RHNA through 2014. Underutilized
parcels in the City may contain substandard historic structures. Afthough the recycling of such properties is
an opportunity to create a positive aesthetic impact, each future development would be reviewed to
determine impacts to historical resources. If necessary, appropriate mitigation measures designed to protect
historic structures would be implemented. Impacts to historical resources duetothe adoption ofthe housing
element would be less than significant. No mitigation measures are necessary.
b) Cause a substantial adverse change In the significance of an archaeological resource pursuant to
§ 15064.5?
Less Than Significant. The City of La Quinta contains one of the densest concentrations of archaeological
sites anywhere in California, because it straddles the shoreline of ancient Lake Cahuilla, a naturally occurring
freshwater lake formed by overflow from the Colorado River. The cultural resources element of the general
plan indicates that372 archaeological sites, both prehistoric and historic, have been identified and recorded
in and around the City. Development of housing projects has the potential to disturb potentially significant
archaeological resources. However, the proposed project itself would not involve ground -disturbing activities
and would not adversely affect archaeological resources. The proposed project would not cause a
substantial adverse change to archaeological resources and no mitigation measures are necessary.
Page 36 • The Planning Center September 2009
3. Environmental A
c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
Less Than Significant. Paleontological resources are nonrenewable, with potential significancetothe area's
natural history. Five soil types occur in the City and its planning area, each with a different history and
potential sensitivityfor paleontological resources: Mesozoicgranitics, Pleistocene older alluvium and terrace
deposits, Lake Cahuilia beds, recent alluvium, and recent dune sand. Of these soil types, Pleistocene older
alluvium and terrace deposits and Lake Cahuilla beds are expected to be highly sensitive for paleontological
resources. Each development that occurs as anticipated by the draft housing element would be considered
on an individual basis during subsequent CEQA review to determine potential impacts to any paleontological
resources. Impacts to paleontological resources due to the adoption of the housing element would be less
than significant.
d) Disturb any human remains, including those Interred outside of formal cemeteries?
No Impact. Any future development that occurs as anticipated by the draft housing element update would
be subject to subsequent review under CEQA—on a project -by -project basis —to determine If any human
remains exist. Moreover, any required general plan amendment, specific plan, or specific plan amendment
would be subject to Native American consultation under Senate Bill (SB 16). However, adoption of the
housing element would not disturb any human remains and there would be no impact
3.6 GEOLOGYAND SOILS
a) Expose people or structures to potential substantial adverse effects, Including the risk of loss,
Injury, or death Involving:
9 Rupture of a known earthquake fault, as delineated on the most recent Alqutst-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. According to the city's general plan master environmental assessment, no active or
potentially active faults are known to occur within the city of La Quints. or Its planning area. Additionally,
California Department of Conservation's Calffomla Geological Surrey lists cities affected byAlquist-Priolo
Earthquake Fault Zones and the City of La Quirts is not included in the list. Therefore, adoption of the
housing element would have no impact and no mitigation measures are necessary.
11) Strong seismic ground shaking?
Less. Than Significant. No active or potentially active faults are known to occur within the City. However,
two of southern Califomia's most active faults, the San Andreas and San Jacinto, are in the vicinity and
would likely generate the most severe ground shaking. The Elsinore Fault, approximately 30 miles
southwest of the City, also has the potential to affect the region. The San Andreas Fault is the closet
major fault system to the City, approximately three miles northeast of the City, and has the potential to
generate a magnitude 7 earthquake. The San Jacinto Fault system is about 10 miles southwest of the
City and is capable of producing a 6.5 to 7.5 magnitude earthquake. Anyfuture developmentthat occurs
in conjunction with the proposed project would be required to adhere to the most recent seismic
standards in the Calffomia Building Code (CBC) adopted by the City of La Quints and would be subject
to CEQA review. Impacts to seismic ground shaking due to the adoption of the housing element would
be less than significant.
2008 La Qainta Housing Element Update Initial Study City of La Quinta • Page 37
3. Environmental Analysis
III) Seismic -related ground failure, including liquefaction?
Less Than Significant. Liquefaction refers to loose, saturated sand or sift deposits that lose their load -
supporting capability when subjected to Intense shaking. Liquefaction is largely limited to lands
containing groundwater (within 50 feet of the ground surface) and sandy, silty soils. Modified Mercalli
Intensities of VII or higher are believed to be required for liquefaction to occur. According to the City's
general plan, much of the eastern portion of the planning area contains groundwater within 30feetofthe
ground surface and is susceptible to liquefaction. lands in the northern and central portion of the
planning area may also be subject to potential liquefaction hazards; however, groundwater is generally
more than 30 feet below the surface in these locations. The Santa Rosa and Coral Reef Mountains and
their slopes are underlain by bedrock and not susceptible to liquefaction. Any future development that
occurs under the draft housing element would be subject to future CEQA review and consideration of
potential soil -related impacts. Impacts to seismic ground failure due to the adoption of the housing
element would be less than significant.
Iv) Landslides?
Less Than Significant. Rock slides and landslides can be expected to occur on steep slopes in the
south-central portion of the planning area and western region of the City. Developments at the base of
the Santa Rosa and Coral Reef Mountains, where bedrock is intensely fractured or jointed, are
particularly vulnerable to selsmically induced rockfali. Manufactured slopes mayalso be subjectto failure
f not engineered to resist seismic groundshaking. Therefore, adequate building setbacks are necessary
to provide a protective buffer between development and unstable slopes. Each development project
occurring within the City limits is required to prepare a site -specific geotechnkal study and comply with
the Uniform Building Code (UBC). In addition, the City's hillside conservation zone ordinance limits
development in areas with slopes greater than 20 percent, and defines permitted land uses in areas with
slopes less than 20 percent. Adoption of the housing element would result in upzoning of some vacant
and underutilized lands in the City limits to accommodate additional lower income housing units per
RHNA allocation. However, these areas are already zoned residential and subject to standard
environmental review process when development occurs. Therefore, site -specific landslide impacts
would be addressed at the time of development and the adoption of the proposed housing element
would not adversely impact the slope stability. Impacts to landslides due to the adoption of the housing
element would be less than significant.
b) Result in substantial soil erosion or the loss of topsoil?
Less Than Significant. The Coachella Valley is highly vulnerable to wind erosion. The extreme aridity of the
region and the coastal air masses that are funneled through the San Gorgonio Pass create strong winds that
transport large quantifies of sand through the valley. The northern portion of the planning area is most
susceptible to blowsand. Future developments anticipated bythe draft housing element would involve land
disturbance that would result in soil erosion and the loss of topsoil. However, future development projects
would be required to prepare erosion control plans and/or incorporate best management practices to
minimize potential erosion and sedimentation Impacts. The vacant and underutilized lands identified in the
draft housing element are already zoned residential and the adoption of the housing element would not
increase the area of disturbance. Impacts to soil erosion due to the adoption of the housing element would
be less than significant.
Page 38 • The Planning Center September 2009
3. Environmental A
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 -she landslide, lateral spreading, subsidence,
liquefaction, or collapse?
Less Than Significant. Rocks and sediments that underlie the City include granite associated with the Santa
Rosa Mountains, lacustrine (lake) deposits from former bodies of water in the Coachella Valley, alluvium
(stream deposits) shed from local mountains, and blowing sand deposits. Granite (go functions as the
foundation for regional soils. The Santa Rosa Mountains consist of hard crystalline granite. Granitic outcrops
are found in steep hills and slopes in the south-central and western portions of the City. Although these rocks
are generally stable, they can pose a rockfall hazard to areas that are adjacent and downslope. Quaternary
conglomerate (Qc) and quaternary terrace (Qt) deposits occur on top of the granite foundation, along the
margins of the valley. Surface outcrops of quaternary terrace deposits are found immediately south of Lake
Cahuilla. The next layers of sediment that compose the valley floor are Interbedded quaternary lake and
alluvial deposits (QVQal). These units consist of deposits from ancient Lake Cahuilla and other large lakes,
imbedded with alluvial (stream -deposited) deposits. Sand -dune deposits (Qsd) primarily occur immediately
south of Highway 111. Ground subsidence is the gradual settling of the ground surface with little or no
horizontal movement Earthquakes can cause abrupt changes in the elevation of the ground surface,
depending on the Intensity and duration of ground shaking and the density of subsurface soils. Ground
subsidence is also associated with the extraction of oil, gas, or groundwater.
The draft housing element identifies opportunity areas for housing development and strategies to achieve the
regional housing needs production goals. The proposed project is the draft housing element, not the
Individual, subsequent housing development projects or required zone changes needed to implement the
respective projects. Therefore, the proposed project would not result in any housing construction; future
development that occurs underthe draft housing element would be subjectto CEQA review, consideration of
potential soil -related Impacts, and any necessary improvements to ensure long-term gootechnical stability.
Impacts related to soil due to the adoption of the housing element would be less than significant.
d) Be located on expansive soil, as defined In Table 18-1-B of the Uniform Building Code (1994),
creating substantial risks to life or property?
Less Than Significant. Expansive soils shrink or swell as the moisture content decreases or increases.
Structures built on these soils may experience shifting, cracking, and breaking as soils shrink and subside or
expand. The lacustrins deposits of ancient take Cahuilla and other large lakes that once existed in the
Coachella Valley contain significant amounts of clay. As a result, expansive soils constitute a potential hazard
In areas near Lake Cahuilla. Any future development that occurs under the draft housing element would be
subject to future CEQA review and consideration of potential soli -related Impacts. Necessary improvements
to ensure long-term geotechnical stability would be required. Impacts related to soil due to the adoption of
the housing element would be less than significant.
e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water
disposal systems where sewers are not available for the disposal of waste water?
No Impact. Although individual septic tanks are being used in some areas of the City, future residential
developments that occur in conjunction with the draft housing element would be required to connect to the
local sewer system provided by Coachella Valley Water District. Future developments that occur in
conjunction with the proposed project would utilize the local sewer system. Therefore, no significant impacts
would result from septic tanks or other onsite wastewater disposal systems.

17 HAZARDS AND HAZARDOUS MATERIALS
a) Create a significant hazard to the public or the environment through the routine transport, use or
disposal of hazardous materials?
Less Than Significant. The draft housing element designates adequate sites for potential future residential
development that could accommodate any unmet portion of the RHNA through 2014. Common household
items such as fertilizers, paint, chlorine products, and other cleaners and solvents may be considered
hazardous or toxic. However, these items would be used in small amounts and would not require routine
transport, use, or disposal in large quantities that could result in a significant hazard. Use of hazardous
materials adjacent to residential uses is minimal and any regular use in large amounts would be subject to
subsequent CEQA review and regulatory requirements. Therefore, impacts would be less than significant.
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. Future developments anticipated by the draft housing element may be located In the
vicinity of sites where hazardous materials are contained.
Releases of hazardous materials may occur during a natural disaster. Likewise, improperly stored containers
of hazardous substances may overturn or break, pipelines may rupture, and storage tanks may fail.
However, future development projects would be subject to CEQA review and analyzed for the potential
release of hazardous materials Into the environment. Impacts associated with hazardous materials dueto the
adoption of the housing element would be less than significant.
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. The proposed project consists of an updated determination of housing needs in the
City. The proposed project would not directly emit hazardous emissions and would not involve the handling
of hazardous or acutely hazardous materials. There are schools in the City limits, but the updated housing
element would not result In hazardous air emissions within one -quarter mile of these schools. Impacts
associated with hazardous materials due to the adoption of the housing element would be less than
significant.
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. No known hazardous materials sites are listed for the City. However, a project -
specific records search would be required through the City s environmental review process to confirm the
absence of any known hazardous material site. Impacts associated with hazardous materials due to the
adoption of the housing element would be less than significant.
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
for people residing or working In the project area?
Less Than Significant. The Bermuda Dunes Airport is approximately 3,000 feet north of the City of La
Quinta, and Jacqueline Cochran Regional Airport is approximately 3.5 miles east of the City. The City is not
Page 40 • The Planning Center September 2009
3. Environmental
in the airport influence policy area. Impacts from airport -related hazards due to the adoption of the housing
element would be less than significant.
f) For a project within the vicinity of a private airstrip, would the project result Ina safety hazard for
people residing or working in the project area?
No Impact. There are no private airstrips in the City of La Quinta; therefore, the proposed project would not
result in any significant safety hazards from activity related to a private airstrip/airport. The project would not
cause safety hazards and no impact would occur.
g) Impair implementation of or physically interfere with an adopted emergency response plan or
emergency evacuation plan?
Less Than Significant An emergency operations center (EOC) is the base of operations during emergency
situations and is considered a critical facility. The La Quints Civic Center building has been designated as the
City's primary EOC, and the Senior Center has been designated as an alternative EOC. The Riverside County
Administrative Centers in Riverside and Indio, which have been designated as the county's EOCs, and the
county's mobile EOC may also be employed to provide assistance during an emergency. Adoption of the
draft housing element would not impair operation of EOC9 or physically interfere with the emergency
response plan. Adoption of the housing element would have a less than significant impact on emergency
response plans.
h) Expose people or structures to a significant risk of loss, Injury or death involving wildland fires,
Including where wlldlands are adjacent to urbanized areas or where residences are Intermixed
with wildlands?
No Impact. According to the County of Riverside General Plan, the City of La Quinta and its vicinity have low
wildfire susceptibility. The City is built out with urban uses and does not contain wildland vegetation. The
project would not create any hazards arising from wildland fires, and therefore no impact would occur.
IS HYDROLOGYAND WATER QUALITY
a) Violate any water quality standards or waste discharge requirements?
Less Than Significant. The draft housing element designates adequate sites for potential future
development that could accommodate any unmet portion of the RHNA through 2014. As these potential sites
are developed, wastewater would be discharged into the local sewer system and onsits drainage would flow
into the City's existing storm drain system. As part of Section 402 of the Clean Water Act (CWA), the U.S.
Environmental Protection Agency (EPA) has established regulations under the National Pollution Discharge
Elimination System (NPDES) program to control direct stormwater discharges. Future development would be
required to comply with the NPDES program and the standards under the Colorado River Basin Regional
Water Quality Control Board (Region 7). Additionally, through the City's development review process, future
projects would be evaluated for potential water quality impacts. Where needed, future development projects
would be required to prepare water quality plans and/or Incorporate best management practices (BMP) into
their construction operations to reduce potential water quality impacts. Impacts to water quality due to the
adoption of the housing element would be less than significant.

3. Environmental Analysis
b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge
such that there would be a net deficit in aquifer volume or a lowering of the local groundwater
table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would
not support existing land uses or planned uses for which permits have been granted)?
Less Than Significant. The Coachella Valley Water District (CVWD) provides water service to the City. The
City's primary domestic water sources are irrigation canal water and groundwater. The anticipated
development under the draft housing element update would increase water consumption in the City as well
as increase dependence on local and imported supplies of groundwater. However, the proposed project is
the draft housing element, not the individual, subsequent housing development projects or required zone
changes needed to implement the respective projects. Therefore, although the subsequent housing
development may have adverse impact on groundwater supplies, the proposed project would have no
impact on the water supplies. Any future development would be subject to CEQA review and potential
impacts to groundwater supply and recharge would be analyzed. Impacts to groundwater due to the
adoption of the housing element would be less than significant. No mitigation measures are necessary.
c) Substantially alter the existing drainage pattern of the site or area, including through the alteration
of the course of a stream or river, in a manner which would result In a substantial erosion or
siltation on- or off -site.
Less Than Significant. The development discussed by the draft housing element could require substantial
alteration of drainage patterns. None of the housing sites identified in the draft housing element are located
within the vicinity of or would after the course of a stream or river. Considering the avid condition of the area
soils, substantial erosion impact is anticipated. However, future development projects would be subject to
CEQA review and would adhere to the City's standard practices designed to prevent erosion and siltation
during the construction phase. Impacts to the drainage pattern due to the adoption of the housing element
would be less than significant
d) Substantially alter the existing drainage pattern of the site or area, including through the alteration
of the course of a stream or river, or substantially increase the rate or amount of surface runoff in
a manner which would result in flooding on- or off -site?
Less Than Significant. The development discussed bythe draft housing element could require substantial
alteration of drainage patterns. None of the housing sites identified in the draft housing element are located
within the vicinity of or would alter the course of a stream or river. The majority of the City is built out and
served by an established storm drainage system. Future developments may involve changes to the existing
drainage network. However, any future development would be subject to CEQA review and potential
drainage patterns and surface runoff impacts would be analyzed. Therefore, impacts due to the adoption of
the housing element are less than significant.
e) Create or contribute runoff water which would exceed the capacity of existing or planned storm
water drainage systems or provide substantial additional sources of polluted runoff?
Less than Significant. Approval of the housing element would result in increased residential density in some
vacant and underutilized lands in the City limits. Increased areas of impervious surfaces In the City limits
would create additional sources of potentially polluted runoff. However, future development would be subject
to CEQA review and would comply with the City and NPDES regulations regarding stormwater pollution
prevention measures during construction and operation. Therefore, Impacts from runoff water due to the
adoption of the housing element would be less than significant.
Page 42 • The Planning Center September 2009
3. Environmental
f) Otherwise substantially degrade water quality?
Less Than Significant. The draft housing element designates adequate sites for potential future
development that could accommodate any unmet portion of the RHNA through 2014. Construction activities
and long-term operation of the future development have the potential to degrade water quality through an
increase in water pollutants, including sediments. Future projects would be evaluated on an individual basis
for their potential to degrade water quality, and projects must comply with any applicable water quality
standards and regulations. Impacts to water quality due to the adoption of the housing element would be
less than significant.
g) Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary
or flood Insurance Rate Map or other flood hazard delineation map?
Less Than Significant. According to the Federal Emergency Management Agency (FEMA), some areas of
the City are in the 100-year flood zone. However, potential development as anticipated under the draft
housing element would be evaluated on a project -by -project basis and would be required to comply with the
City's building codes and regulations. No mitigation measures are necessary.
h) Place within a 100-year flood hazard area structures which would Impede or redirect flood flows?
Less Than Significant. See 3.89.
1) Expose people or structures to a significant risk of lose, Injury or death involving flooding,
Including flooding as a result of the failure of a levee or dam?
No Impact. According to the Western Coachella Valley Area Plan, the City of La Quinta is not in the dam
hazard zone. Adoption of the draft housing element would not expose people or structures to significant
inundation impact due to the failure of a levee or dam. No impact would resultfrom the proposed project. No
mitigation measures are necessary.
J) Inundation by selche, tsunami, or mudflow?
Less Than Significant. A selche Is a surface wave created when a body of water Is shaken, usually by
earthquake activity. Seiches are of concern relative to water storage facilities because inundation from a
selche can occur lithe wave overflows a oontainmentwall, such as the wall of a reservoir, water storagetank,
dam, or other and icial body of water. Flood control and reservoir facilities that experience seiching could
pose a threat to nearby development by falling and inundating developed lands. Lake Cahutllaand recharge
basins southeast of Lake Cahuilla have the potential of seiching. However, each development project would
be subject to site -specific environmental review and, If near Lake Cahuilla or recharging basins, additional
analysis based on issues such as distance, Intervening development, and topography would be provided.
La Quints is approximately 00 miles from the nearest coastline; therefore, a tsunami does not pose a hazard
to the City. No impact is anticipated.
Mudflows are landslide events in which a mass of saturated soil flows downhill as a very thick liquid. Granite
soil functions as the foundation for regional soils; especially near steep hills and slopes. Since granite soils
have low potential for saturation, it Is unlikely that housing development would be adversely Impacted by
mudflows. Future development projects would be evaluated on an individual basis and would be required to
comply with the City's building codes and regulations. Impacts to water quality due to the adoption of the
housing element would be less than significant.

3.9 LAND USE AND PLANNING
a) Physically divide an established community?
No Impact. Adoption of the draft housing element would result in increased housing capacity on vacant and
underutilized sites through rezoning for greater density. However, identified vacant and underutilized sites
are already zoned residential and the adoption of the draft housing element would not itself result in the
actual housing development. Therefore, it would not physically divide a community and no impacts are
anticipated. No mitigation measures are necessary.
b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over
the project (Including, but not limited to the general plan, specific plan, local coastal program, or
zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect?
Less Than Significant. The project is an update to the draft housing element of the City's general plan, and
would become the new housing element upon approval by the City Council. The City of La Quinta is not
within the coastal zone, and so is not subject to a local coastal program. Implementation of the draft housing
element would require amendment of the zoning map and the municipal code to accommodate the unmet
portion of the RHNA allocation. The housing element also proposes program and policy changes to create
development standards for residential -above -commercial development. However, the adoption of the draft
housing element would not itself result in housing development Future housing development as identified in
the draft housing element would be subject to project -specific CEQA review, including an evaluation of
conflicts with any applicable policies, programs, and regulations. Impacts associated with the adoption of the
draft housing element with respect to consistency to land use plans, policies, and regulations, therefore,
would be less than significant, and no mitigation measures are necessary. .
c) Conflict with any applicable habitat conservation plan or natural community conservation plan?
Less Than Significant Impact. The City of La Quinta lies within the Coachella Valley Multiple Specific
Habitat Conservation Plan. The City is also part of the Coachella Valley Fringe -Toed Lizard Habitat
Conservation Plan and a portion of the City Is included In the Peninsular Bighorn Sheep Critical Habitat.
Implementation of the draft housing element would require amendment to the zoning map and the zoning
ordinance to accommodate the unmet RHNA allocation. However, the vacant and underutilized areas
identified in the draft housing element are already designated as residential uses, and the increased
development density proposed by the draft housing element would not convert any natural open space area
to urban uses. Additionally, each development project would be required to comply with the applicable
habitat conservation implementation plan. Impacts would be less than significant and no mitigation
measures are necessary.
3.10 MINERAL RESOURCES
a) Result in the loss of availability of a known mineral resource that would be a value to the region
and the residents of the state?
Less Than Significant. According to the City of La Quints. General Plan, a small area southwest of Lake
Cahuilla is designated as mineral recovery zone 2 (MRZ-2), indicating that significant mineral deposits are
present. This site once functioned as a sand and gravel mine, but has since been converted to a residential
golf course development In addition, the Santa Rosa Mountains lie within mineral recovery zone 3 (MRZ3),
indicating the presence of mineral resources, the significance of which cannot be determined from available
data. However, Santa Rosa Mountain is designated as open space and would not be impacted by the draft
Page 44 • The Planning Center September 2009
3. Environmental
housing element. No additional construction is proposed in areas designated as potentially containing
mineral resources. In addition, future development would be required to go through the CEQA process and
any impacts would be assessed at that time. No impact is anticipated and no mitigation measures are
necessary.
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?
Less Than Significant. See 3.10a.
all NOISE
a) Exposure of persons to or generation of noise levels In excess of standards established In the
local general plan or noise ordinance, or applicable standards of other agencies?
Less Than Significant. The draft housing element designates adequate sites for potential future
development that could accommodate any unmet portion of the RHNA through 2014. Future construction
and operation activities would increase noise levels throughoutthe City. However, future development would
be evaluated on an individual basis and would comply with City, federal, and state guidelines on vehicle
noise, roadway construction, occupational noise and noise abatement, and insulation standards. Impacts
from noise due to the adoption of the housing element would be less than significant
b) Exposure of persons to or generation of excessive groundbome vibration or groundbome noise
levels?
Less Than Significant. It is possible that groundbome vibration or groundbome noise would occur during
the construction phase of future development projects articipated by the draft housing element Update.
Although groundborne vibration and groundbome noise are common results of the construction phase, each
development would be subject to CEQA review and consideration of potential groundbome vibration and
groundborne noise impacts. Impacts regarding noise due to the adoption of the housing element would be
less than significant., ., ' ,11
c) A substantial permanent Increase in ambient noise levels in the project vicinity above levels
existing without the project?
No Impact. The draft housing element designates adequate sites for potential future developmentthat could
accommodate any unmet portion of the RHNA through 2014. Traffic related to the future developments
would result in a long-term increase in ambient noise levels. However, depending on the size of each
development, this increase may be noticeable to some people but may not be substantial or significantly
Impact surrounding sensitive uses. Future development would be subjectto CEQA review and consideration
of potential noise impacts. Therefore, the Impacts regarding noise due to the adoption of the housing
element would be less than significant.
d) A substantial temporary or periodic Increase in ambient noise levels in the project vicinity above
levels existing without the project?
No Impact. See 3.110.
2008 La Quinta Housing Element Update Initial Study City of La Quinta • Page 45
3. Environmental Analysis
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 expose people residing
or working in the project area to excessive noise levels?
Less Than Significant. The Bermuda Dunes Airport is approximately 3,000 feet north of the City of La
Quinta, and Jacqueline Cochran Regional Airport is approximately 3.5 miles east of the City. There may be a
potential for future projects to be exposed to excessive noise levels. The projects would be required to go
through the CEQA process and comply with the airport land use plan. Impacts regarding excessive noise
levels due to the adoption of the housing element would be less than significant.
f) For a project within the vicinity of a private airstrip, would the project expose people residing or
working in the project area to excessive noise levels?
No Impact. There are no private airstrips in the City of La Quinta. Future development in La Quinta would not
be exposed to excessive noise levels due to a private airstrip. No impact is anticipated and no mitigation
measures are necessary.
M12 POPULATIONANDHOUSING
a) Induce substantial 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 The proposed project consists of an updated assessment of housing needs in the
City, and involves both changes to and continuation of policies and procedures the City uses in addressing
those needs. The project identifies sites in the City suitable for the development of housing and Involves
other efforts to facilitate the development of housing in the City. The draft housing element discusses the
City's housing production goal and how the City would achieve the regional housing needs production
goals. The City's RHNA housing goals are consistent with the existing general plan and SCAG regional
growth projections for the City of La Quinta. The draft housing element itself would not involve any
development projects and would not directly result in the construction of any housing units. However,
implementation of the housing element would require zone changes to allow development of higher density
housing than is currently permitted for some of the areas identified. Project -specific development to meetthe
goals identified in the draft housing element, however, would be subject to CEQA review, including an
assessment of population and housing impacts. Adoption of the housing element, therefore, would have a
less -than -significant impact and no mitigation measures are necessary.
b) Displace substantial numbers of existing housing, necessitating the construction of replacement
housing elsewhere?
Less Than Significant. Adoption of the draft housing element would not displace any housing, and would
not involve demolition of substantial numbers of existing housing units or other structures. However, any
future development projects proposed in accordance with the draft housing element would be subject to
CEQA review. Therefore, the adoption of the housing element would have a less -than -significant impact.
Page 46 • The Planning Center September 2009
3. Environmental
c) Displace substantial numbers of people, necessitating the construction of replacement housing
elsewhere?
No Impact. The proposed project itself would not displace any people and would not involve demolition of
any housing units or other structures. Any future projects proposed In accordance with the draft housing
element would provide housing to meet the RHNA housing goals for the City. No impacts would occur.
3.13 PUBLIC SERVICES
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 any of the public
services:
a) Fire protection?
Less Than Significant. Fire protection service is provided to the City of La Quints. by the Riverside County
Fire Department. The fire department maintains three fire stations: Station 32 at 78136 Frances Hack Lane,
Station 70 (PGA West) at 54001.Madison Street, and Station 93 (North La Quints) at 44555 Adams Street
Station 32 would be related to anew 7,500 square feet facility in 2010. New development anticipated to
achieve the draft housing element'goals would Increase fire protection service needs in the City, and may
require Improvements to existing facilities or increases in staffing and equipment Each future development
would be subject to CEQA review and evaluation of potential impacts to the fire department Adoption of the
housing element would not result in direct impacts to fire protection services, and therefore impacts would 88
be less than significant and no mitigation measures are necessary.
b) Police protection?
Less Than Significant. The City contracts with the County of Riverside to provide police services to the City.
The Riverside County Sheriff's Department provides patrol officers, motorcycle officers, school resource
officers, community service officers, investigators, gang task force members, a narcotics task force, a special
enforcement team, a traffic reconstruction unit, and a community policing officer. The patrol division for the
La Quints Police Department covers an area of approximately 35 square miles and provides service to an
estimated population of 44,000 residents. Uniformed patrol officers are assigned oaths initial responders for
all calls for service within the City of La Quints. In 2008, the patrol division responded to 30,548 calls for
service or approximately 83 calls for service per day, with an average response time of 4 minutes and 58
seconds for priority one calls. New developments anticipated to achieve the draft housing element goals
would increase police protection service needs in the City, and may require Improvements to existing
facilities or increases in staffing and equipment. Each future development would be subject to CEQA review
and evaluation of potential impacts on the police department Impacts to police protection due to adoption of
the housing element would be less than significant and no mltigation measures are necessary.
c) Schools?
Less Than Significant. School services are provided by the Desert Sands Unified School District for
students west of Jefferson Street and north of Avenue 48, and by the Coachella Valley Unified School District
for students east of Jefferson Street and south of Avenue 48. Development of additional housing would
increase the demand on schools; therefore, additional facilities and staffing would be necessary to
accommodate the growth. Future development would be subject to CEQA review and impacts on school
2008 La Qmnia Hooting Element Update Initial Study City of Is. Quinta • Page 47
3. Environmental Analysis
facilities would be considered. Impacts to schools due to adoption of the housing element would be less
than significant and no mitigation measures are necessary.
d) Parks?
Less Than Significant. Adoption of the draft housing element would result in additional demand on parks to
accommodate the growth, Future developments would be subject to CEQA reviewand impacts on local park
and recreational facilities would be considered. Impacts on parks due to adoption of the housing element
would be less than significant. No mitigation measures are necessary.
e) Other public facilities?
Less Than Significant. The draft housing element designates adequate sites for potential future
development that could accommodate any unmet portion of the RHNA through 2014. Future development
would be subject to CEQA review and impacts on other public facilities would be considered. Impacts on
other public facilities due to adoption of the housing element would be less than significant and no mitigation
measures are necessary.
a 14 RECREATION
a) Would the project 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. The range of parks and recreational facilities in the City includes parks, trails, and
community center facilities. The proposed project consists of an updated assessment of housing needs in
the City and changes to the policies and procedures the City uses in addressing those needs. The project
identifies sites in the City suitable for the development of housing and involves other efforts to facilitate the
development of housing in the City. The draft housing element itself would not involve any development
projects and would not directly result in the construction of any housing units. Future developments
anticipated by the draft housing element would be subject to CEQA review and would either be required to
pay residential development fees and in -lieu fees to the City for the development and maintenance of park
facilities or provide improved parks. If fees are necessary, the amount would be determined in conjunction
with the City's Community Services Department during the City's approval process for those projects.
Impacts to parks and recreational facilities due to the adoption of the housing element would be less than
significant.
b) Does the project Include recreational facilities or require the construction or expansion of
recreational facilities, which might have an adverse physical effect on the environment?
Less Than Significant. Approval of the housing element would not impact any recreational facility; however,
implementation of the housing element is reliant on future development assumptions. Future development
would increase the demand for parks and recreational facilities in the City. The Quimby Act allows local
governments to exact the dedication of parkland or in -lieu fees or both from developers based on a standard
of three acres per thousand population. The provisions of the Quimby Act apply only to neighborhood and
community parks and do not include regional parks. The General Plan indicates that the City needs an
additional 185.2 acres of parkland at general plan buiidout, Therefore, future projects would be subject to
CEQA review and would either be required to pay residential development fees and in -lieu fees to the Cityfor
the development and maintenance of park facilities or provide improved parks. If fees are necessary, the

amount would be determined by the City during the City's approval process for those projects. Impacts to
recreational facilities due to the adoption of the housing element would be less than significant.
X 15 TRANSPORTATIONITRAFFiC
a) Cause an increase In traffic, which is substantial In relation to the existing traffic load and capacity
of the street system (I.e., result in a substantial increase in either the number of vehicle trips, the
volume to capacity ratio on roads, or congestion at Intersections)?
Less Than Significant The proposed project consists of an updated assessment of housing needs in the
City. Future development to meet the housing goals would result in an increase in vehicle trips that would
have the potential to affect traffic service levels and result in congestion at intersections in the City. Some of
the areas identified to potentially accommodate future housing would require zone change to facilitate
increased housing density. As with specific development proposals, zoning changes are discretionary
actions and subject to CEQA review. The development proposals and any required zone changes would be
required to evaluate potential traffic Impacts in comparison to applicable level of service standards for the
City of La Quinta and neighboring jurisdictions. Roadway and circulation improvements proposed as part of
the entitlements and projects would also be reviewed. it should be noted that the rezoning actions would be
considered as part of the City's General Plan update, which would include review of potential traffic Impacts
due to all proposed land use changes. Therefore, any impacts associated with traffic due to the adoption of
the housing element would be less than significant.
b) Exceed, either Individually or cumulatively, a level of service standard established by the county
congestion management agency for designated roads or highways? M
Less Than Significant Development anticipated by the draft housing element could contribute to — —
cumulative countywide traffic impacts. However, any future projects would be evaluated for potential traffic
Impacts through the CEQA process, and appropriate mitigation measures may be required. It should be
noted that the rezoning actions would be considered as part of the City's General Plan update, which would
Include review of potential traffic impacts due to all proposed land use changes. Therefore, impacts
associated with traffic due to the adoption of the housing element would be less than significant and no
mitigation measures are necessary.
c) Result Ina change in air traffic patterns, Including either an Increase in traffic levels or a change in
. location that results in substantial safety risks?
No Impact. The draft housing element itself would not involve building any structures and thus would not
result in any changes to air traffic patterns or in any substantial safety risks related to aircraft traffic.
Additionally, future development anticipated under the draft housing element would comply with the airport
land use plan and would not result in changes to air traffic patterns. Therefore, no impact would occur.
d) Substantially Increase hazards due to a design feature (e.g., sharp curves or dangerous
Intersections) or incompatible uses (e.g., farm equipment)?
Less Than Significant. The increased amount of traffic and turning movements associated with the
Increased housing development would increase hazards to motorists, pedestrians, and bicyclists. The draft
housing element itself would not involve building any structures. At the time of a zoning change or
development proposal, each project would be evaluated through the City's environmental review process.
Where needed, appropriate mitigation measures would be required. Adoption of the housing element would
have a less -than -significant impact and no mitigation measures are necessary.
2008 La Qxinta Hoxrmg Element Update Initial Study City of La Qxiwa • Page 49
3. Environmental Analysis
e) Result in inadequate emergency access?
Less Than Significant. Any future development that is anticipated underthe draft housing element would be
required to conform to traffic and safety regulations that specify adequate emergency access measures.
However, because adequate emergency access is impossible to determine with any precision without
specific details regarding each development, any future development would be evaluated to determine
adequacy of emergency access on a project -by -project basis. Impacts regarding inadequate emergency
access due to the adoption of the housing element would be less than significant.
f) Result in inadequate parking capacity?
Less Than Significant. Development of residential dwelling units is anticipated under the draft housing
element. Future development would be evaluated to determine adequacy of parking and would be required
to comply with City parking standards. Therefore, impacts associated with parking due to the adoption of the
housing element would be less than significant.
g) Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus
turnouts, bicycle racks)?
Less Than Significant. Public transit service is provided to the City of La Quinta by the Sunline Transit
Agency, and there are existing bicycle routes and shared routes within the City. The City is also developing
golf cart routes and design guidelines. The project itself would not have any significant impact on facilities for
alternative transportation, such as bus turnouts or bicycle racks. However, any future development would
comply with adopted policies, plans, or programs that support alternative transportation. Impacts to adopted
policies, plans, or programs due to the adoption of the housing element would be less than significant.
116 UTILMES AND SERVICE SYSTEMS
a) Exceed waste water treatment requirements of the applicable Regional Water Quality Control
Board?
Less Than Significant. The CVWD provides sewage collection and treatment service for the City.
Wastewater collected north of Miles Avenue is conveyed to the CVWD water reclamation plant (WRP) No. 7
at Madison Street and Avenue 38. Wastewater from the remaining area is conveyed to the WRP No. 4 on
Avenue 63, between Fillmore and Pierce Streets. Wastewater treatment at the CVWD facility is required to
meet applicable regional water quality control board standards. Through the City's environmental review
process, future development would be evaluated for potential impacts to wastewater treatment facilities.
Where needed, appropriate mitigation measures would be required to reduce potential impacts. Impacts to
wastewater treatment due to adoption of the housing element would be less than significant.
b) Require or result in the construction of new water or wastewater treatment facilities or expansion
of existing facilities, the construction of which could cause significant environmental effects?
Less Than Significant. The City's sewage is diverted to two water reclamation plants, WRP No. 7 and WRP
No. 4. WRP No. 4 is a 7-million-gallon-per-day (mgd) treatment facility in Thermal and is planned for
expansion in the near future to 9.9 mgd. WRP No. 7 is a 5 mgd secondary treatment facility with a current
tertiary treatment capacity of 2.5 mgd. CVWD plans to expand its tertiary treatment capacity to 7.5 mgd. The
draft housing element identifies adequate sites for potential future development that could accommodate any
unmet portion of the RHNA through 2014. Additional residential development in the City would increase the
wastewater treatment demand in the City and could require expansion or construction of wastewater
Page 50 •The Planning Center September 2009
3. Environmental Analysis
conveyance and treatment systems. Each development proposal would be required to prepare a site -specific
evaluation to demonstrate the adequacy of the existing sewer system in coordination with CVWD. Any future
projects would be required to consult with CVWD to estimate the level and type of demand to determine the
significance of impacts to existing and planned levels of service and to develop measures to avoid or reduce
potentially significant impacts to less than significant. The impacts would be less than significant.
c) Require or result in the construction of new storm water drainage facilities or expansion of
existing facilities, the construction of which could cause significant environmental effects?
Less Than Significant. The CVWD operates and maintains regional stormwater management facilities
extending from Cathedral City to Salton City, including the City of La Quints. The backbone of the CVWD
stormwatersystem is 25 miles of naturally occurring Whitewater River bed. Because the river spreads across
the lower valley during flooding, it was channelized. It is the Coachella Valley Stormwater Channel
downstream from Point Happy in to Quints near Highway 111 and Washington Avenue. The riverbed and
24.5-mile channel are fed by several smaller channels, dikes, and levees designed and builtto collect rapidly
moving floodwater as it pours from the adjacent mountains onto the valley floor. Within CV WD% boundaries
there are 16 stormwater protection channels. These and other facilities have a length of 133 miles.
Existing storm drain lines would be utilized by future developments proposed by the draft housing element.
Future development could Increase the amount of stormwater runoff over the long term as a result of
increases in impervious surfaces, which may require alterstion to existing stormwater drainage facilities in the
area. However, any future project would be subject to CEQA review and consideration of any potential
impacts on stormwater drainage facilities. Impacts to stormwater drainage facilities due to the adoption of the
housing element would be less than significant and no mitigation measures are necessary. MKh
d) Have sufficient water supplies available to serve the project from existing entitlements and
resources, or are new or expanded entitlements needed?
Less Than Significant. The principal water supplies of the Coachella Valley are local groundwater and
Colorado River water imported through the Coachella Canal. According to the CVWD's 2005 urban water
Management Plan, by 2015 CVWD is projected to receive approximately 60 percent of its water from the
Coachella Canal, 22 percent from the groundwater, 12 percent from the State Water Project, and
approximately 6 percent from recycled and desalinated sources. The draft housing element would allow
Increased residential density in the City and therefore generate additional water demand. However, adoption
of the housing element itself would not result in actual construction. Future development would be subject to
CEQA review and would need to demonstrate water availability. Impact on water supplies due to the
adoption of the housing element would be less than significant.
e) Result In a determination by the waste water treatment provider, which serves or may some 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. The CVWD provides wastewater treatment for the City. The City's sewage is diverted
to WRP No. 4 and WRP No. 7. Future development would be required to comply with the CEQA process to
determine the type and significance of Impacts to existing and planned levels of service and to develop
measures to avoid or reduce potentially significant.impacts to' less than significant, If possible. Impacts on
the capacity for wastewater treatment due to the adoption of the housing element would be less than
significant.
2008 La Quinta Housing Element Update Initial Study City of La Qutnta • Page 51
3. Environmental Analysis
f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste
disposal needs?
Less Than Significant. The City of La Quinta contracts with Burrtec Waste and Recycling Services for solid
waste hauling and disposal. The predominant receiving landfill isthe Lamb Canyon Sanitary Landfill at 16411
State Route 79 in the City of Beaumont, Riverside County. Other landfills in Riverside County used bythe City
are the El Sobrante Landfill in Moreno Valley and Badlands Sanitary Landfill. The Lamb Canyon Sanitary
Landfill has a permitted maximum disposal capacity of 3,000 tons per day and is scheduled to close in 2023.
The additional residential densityallowed bythe draft housing element would increase solid waste disposal
needs. However, the proposed project would not result in actual construction. Therefore, impacts regarding
solid waste due to the adoption of the housing element are less than significant and no mitigation measures
are necessary.
g) Comply with federal, state, and local statutes and regulations related to solid waste?
Less Than Significant. Any future development would comply with federal and state laws regulating solid
waste disposal. No adverse impact would occur, and no further analysis of this issue is required.
117 MANDATORY FINDINGS OF SIGNIFICANCE
a) Does the project have the potential to degrade the quality of the environment, substantially reduce
the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-
sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict
the range of a rare or endangered plant or animal or eliminate important examples of the major
periods of California history or prehistory?
No Impact. The proposed project is located in the City of La Quints. Adoption of the draft housing element
Itself would not result in the actual physical development of residential units. Therefore, no significant
biological or historical impacts are anticipated to result from implementation of the proposed project. No
mitigation measures are necessary.
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. The proposed project involves the implementation of the draft housing element for
the City of La Quints. The draft housing element is a policy document designed to assist the City in future
planning and would not result in the actual development of residential units. Through the City's
environmental review process, future development projects would be evaluated for potential cumulative
impacts at the time of actual zone change or project development. Therefore, no significant cumulative
impact is anticipated and no mitigation measures are necessary.
c) Does the project have environmental effects, which will cause substantial adverse effects on
human beings, either directly or Indirectly?
Less Than Significant. The draft housing element is a policy document designed to assistthe City in future
planning. Through the City's environmental review process, future development projects would be evaluated
for potential cumulative impacts. Where needed, appropriate mitigation measures would be required to
reduce potential impacts to a level of less than significant. No mitigation measures are necessary.
