INTRODUCTION
This document is an Addendum to the certified Final Environmental Impact Report (Final FIR) for the
Country Club of the Desert Specific Plan (CCDSP) SP 99-035 project. This introduction describes the
background of the planning and environmental review process for the CCDSP and the purpose and
organization of this addendum addressing the proposed amendment to the CCDSP.
PURPOSE OF AN ADDENDUM
When a Final FIR has been certified for a project, the California Environmental Quality Act (CEQA) and
the CEQA Guidelines define standards and the procedure for additional environmental review. Sections
1516215164 of the CEQA Guidelines define the standards for determining the level of additional
environmental review required when an FIR has been certified for a project.
When it can be determined that neither the proposed changes to the project, changed circumstances, nor
new information result in the identification of new significant impacts, or the substantial increase in the
severity of significant impacts identified in the certified FIR, an Addendum to an EIR may be prepared.
If new significant impacts or a substantial increase in the severity of impacts would result, then
preparation and circulation of a Subsequent or Supplemental FIR for additional public review is required
by CEQA and the CEQA Guidcl ines. Public review of an Addendum is not mandated by CEQA.
This Addendum to the certified CCDSP Final FIR has been prepared because (1) no substantial changes
are proposed in the project which will require major revisions of the previous EIR due to the occurrence
of new significant effects or a substantial increase in the severity of previously identified significant
impacts; (2) no substantial changes in circumstances under which the project is undertaken will occur
which will require major revisions of the previous EIR due to the occurrence of new significant
environmental effects or a substantial increase in the severitv of previously identified effects; and (3) no
new information of substantial importance which was not known and could not have been known with
the exercise of reasonable diligence at the time the previous FIR was prepared, shows any of the
following: (A) the project will have one or more significant effects not discussed in the previous EIR; (B)
significant effects previously examined will be substantially more severe than shown in the previous EIR;
C) mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and
would substantially reduce one or more significant effects of the project, but the project proponents
lecline to adopt the mitigation measure or alternative; or, (D) mitigation measures or alternatives which
re considerably different from those analyzed in the previous FIR would substantially reduce one or
pnct Scirnees, 1" . ] Add, ndwn Po the
id0 CounhyCluh of the Desert Spectfic Pbm Fiord EIR
Decnnber 2004
Bitroduction
more significant effects on the environment, but the project proponents decline to adopt the mitigation
measure or alternative.
The analysis of the proposed Specific Plan Amendment contained in this Addendum demonstrates that
neither the proposed changes to the project or the circumstances under which the project will occur will
result in any new significant impacts nor any substantial increase in the severity of the impacts identified
in the certified CCDSP Final EIR. This is because the proposed Specific Plan Amendment would
maintain the original development concept with changes to the configuration of the residential and golf
course uses while decreasing the residential density. No new land uses are proposed, and the concept
remains a mix of residential and golf uses. Additionally, no new information of substantial importance
has been identified that indicates the Specific Plan Amendment as currently proposed would result in
any new significant impacts nor any substantial increase in the severity of the impacts identified in the
certified CCDSP Final FIR.
This Addendum provides environmental review of the proposed CCDSP Amendment, comparing the
environmental impacts of this proposal with the impacts identified in the certified CCDSP Final EIR. The
Addendum is structured to provide the following information for each environmental topic area
discussed in the certified EIR: first, a summary of impacts identified in the certified CCDSP Final EIR is
provided. This is followed by an analysis of the proposed CCDSP Amendment project, and these impacts
are compared with the impacts identified in the certified CCDSP Final EIR. This analysis includes, where
applicable, discussion of the City's updated 2002 General Plan as well as other new City, state or local
rules, regulations and ordinances. Last, mitigation measures recommended by this Addendum and
mitigation measures that were adopted for the certified CCDSP Final EIR and are applicable to the
proposed Specific Plan Amendment are provided.
REGIONAL AND LOCAL SETTING
The City of La Quinta encompasses approximately 31 square miles of land area located in the
southwestern portion of the Coachella Valley, in eastern Riverside County. The Coachella Valley is
located between the San Bernardino Mountains and the Santa Rosa Mountains, as shown in Figure 1. La
Quinta is located approximately 18 miles southeast of the resort community of Palm Springs. It is
surrounded by the cities of Indian Wells and Palm Desert to the northwest, Indio, Coachella, the
Augustine Indian Reservation and Thermal to the east, and the Santa Rosa Mountains to the south and
west. The Interstate 10 Freeway (I-10) provides regional east -west access to the Coachella Valley
communities. State Highway 111, a four- and six -lane east -west state highway, provides the primary
regional access to La Quinta and is a major intra-regional and inter -regional route for the Coachella

Valley. Of the five key roadways in the City's circulation network, Jefferson Street provides primary
access to the project site.
The adopted CCDSP Area is shown in Figure 2. The CCDSP Area presently includes 988 acres located in
the southeastern area of the City. The irregular -shaped CCDSP Area is generally bordered by Avenue 52
on the north, Avenue 54 on the south, Monroe Street on the east, Jefferson Street on the west, and the
Coachella Canal on the northwest. The eastern portion of the site is partially bisected in an east -west
direction by Avenue 53, which terminates before the alignment of future Madison Street, and which
would be largely vacated. The existing Avenue 53 right-of-way terminates at the center of Section 10
west of Monroe Street at the property's east boundary. Madison Street intersects with Avenue 52 and
Avenue 54, but does not currently extend across the CCDSP Area.
The land uses in the vicinity of the CCDSP Area include active and fallow agricultural fields,
undeveloped properties, horse stables, and polo fields. A custom home residential subdivision is located
north of the project site beyond Avenue 52. The 1,650-acre PGA West golf and residential community is
located to the south of the project site. Landscape setbacks leading to solid masonry walls with an
average height of 6 feet are located along the outside boundaries of these residential developments. An —_
80-acre, 203-lot single-family residential community is in the process of being developed at the southwest
corner of Monroe Street and Avenue 52, adjacent to the northeast corner of the CCDSP Area. A 40-acre
parcel located along the eastern boundary at Monroe Street has been approved and will record a final
map shortly. In addition, several other properties in the vicinity have approvals and/or are currently
being improved for residential use.
BACKGROUND OF ADOPTED CCDSP
The City of La Quinta prepared an EIR in 2000 for the proposed CCDSP project. The EIR was prepared to
assess the potential environmental impacts associated with the planned development of a golf and
residential community in the City of La Quinta. Approval of a Specific Plan, Tentative Tract Map, a
Conditional Use Permit for Resort Residential uses, as defined by the La Quinta Municipal Code, and
vacation of a portion of public street, Avenue 53, within the project site were requested. The EIR served
as the environmental review document for these actions and the future development of the golf and
residential uses that would be allowed by the proposed Specific Plan. The Draft EIR was circulated for
public review in August 2000 and the Final FIR was completed in November 2000. The Final EIR was
certified on November 21, 2000, and the City adopted the Specific Plnrl.

Introduction
Prior to mitigation, significant effects of the project were identified with regard to consistency with
certain policies of the General Plan, loss of agricultural land, potential geotechnical impacts, hydrology
and water quality impacts, biological resource impacts, traffic and circulation impacts, air quality and
noise impacts, and impacts to public service and utility systems. Measures were identified to mitigate all
of these project impacts to a less than significant level with the exception of the loss of agricultural land,
temporary noise impacts during construction, and air quality impacts. The EIR identified that the project
would contribute to significant cumulative impacts, including the loss of mesquite hummock habitat in
the area and demand for landfill space. A Statement of Overriding Considerations was adopted with
approval of the project which addressed these significant impacts which could not be mitigated to a less
than significant level.
DESCRIPTION OF ADOPTED CCDSP
The adopted CCDSP Area consists of approximately 988 acres. For purposes of development, the CCDSP
Area is divided into the two areas shown on Figure 3. The areas consist of The Hideaway, 636 acres
located between Jefferson and Madison Streets, and Madison Creek, 352 acres located between Madison
and Monroe Streets. The Hideaway has been under development for the past four years in conformance
with the adopted CCDSP. Madison Creek will be built on the remaining undeveloped property lying east
of Madison Street that comprises the balance of the CCDSP Area.
The CCDSP allows golf -related development on 525 acres of the 988-acre site of a private golf course
country club with three 18-hole golf courses and related clubhouse facilities. The adopted CCDSP
currently allows the development of two golf courses with associated clubhouse facilities and a golf
course maintenance area west of Madison Street, and one golf course with associated clubhouse facilities
east of Madison Street.
The CCDSP currently allows development of a variety of single-family homes including custom homes,
detached production homes, detached villas, and attached casitas on 405 acres. The adopted CCDSP
allows development of a total of 819 dwelling units. Of these, 509 were planned for development in The
Hideaway portion of the CCDSP Area, and 310 were to be developed east of Madison Street. The
remaining 61 acres of the Specific Plan Area were to be developed with arterial roadways.
The Hideaway development area is served by a network of roadways, including perimeter roadways and
internal streets serving the golf courses, clubhouse, and residential neighborhoods within the site itself.
Primary access to the Specific Plan Area is provided from an entrance on Jefferson Street. Secondary
access is provided from Avenue 52. Public trails, including multi -use and Class II bicycle

Introduction
trails are planned within the public right of way adjacent to the CCDSP Area, with a portion of these
facilities built or under construction in conjunction with The Hideaway. As of December 2004, 34 homes
are complete, including 32 semi -custom villas and 2 custom homes. Thirteen more villas are under
construction and scheduled to be completed in February 2005 and 23 custom homes are in various stages
of completion. Both golf courses (18 holes each) have been developed, and the main clubhouse is under
construction. Also, the planned infrastructure, consisting of sewer, water, drainage and roadways, is
approximately 75 percent complete.
PROJECT DESCRIPTION
At this time, the City has received an application to amend the CCDSP to add approximately 120 acres of
adjacent land, increasing the size of the Specific Plan Area to 1,108 acres from 988 acres, and to revise the
pattern of allowed land uses within the eastern portion of the CCDSP Area. The applicant is also
requesting that the City approve the following related discretionary actions necessary to implement the
proposed Specific Plan Amendment: (1) a Tentative Tract Map, (2) amendment of the City of La Quinta
General Plan Land Use Plan Map, (3) amendment of the City of La Quinta Zoning Map, and (4) vacation of
a portion of public street, Avenue 53, within the project site. This Addendum serves as the
environmental documentation for these actions and the future development of the golf and residential
uses that would be allowed by the proposed Specific Plan Amendment. The adopted CCDSP Area and
proposed amended CCDSP Area are shown in Table 1, Comparison of Adopted and Proposed CCDSP,
and described, below.

The 120 acres would be added to the northeastern corner of the CCDSP Area, as shown in Figure 4. The
120 acres of land to be added to the CCDSP Area with the proposed Specific Plan Amendment have
physical characteristics similar to the land within the CCDSP Area, prior to development of The
Hideaway. The majority of the 120 acres are fallow agricultural land; however, portions of the site are
currently used as grazing land. An abandoned house and associated structures are also present within
the 120-acre site.

Introduction
The proposed Specific Plan Amendment is referred to as the Madison Creek Specific Plan Amendment.
The proposed Specific Plan Amendment addresses the 352 acres within the CCDSP Area east of Madison
Street and the 120 acres proposed for addition to the CCDSP. The proposed Specific Plan Amendment
would maintain the original development concept, with changes to the configuration of the residential
and golf course uses, and decrease the residential density. No new land uses are proposed, and the
concept remains a mix of residential and golf uses.
The proposed Specific Plan Amendment Area land use plan is shown in Figure 5. Approximately 272
acres would be developed with one private championship golf course and country club uses,
approximately 200 acres would be developed with residential uses and roadways. Primary access would
be from Avenue 52, secondary access from Avenue 54 and additional emergency access from Madison
Street.
Currently, 446 dwelling units are planned for development in The Hideaway portion of the CCDSP Area.
This is 63 fewer than allowed by the adopted CCDSP, which allows these units to be transferred for
development within the CCDSP Area east of Madison Street. Because of this, a total of 373 dwelling units
are currently allowed to be developed within the CCDSP Area east of Madison Street.
The Specific Plan Amendment would allow development of 275 dwelling units, including 225 custom lots
and detached homes and 50 detached villas, in the CCDSP Area east of Madison Street. As noted above,
373 dwelling units are currently allowed to be developed. Therefore, the number of dwelling units that
would be allowed to be developed by the Specific Plan Amendment would be 98 fewer than are allowed
to be developed by the adopted CCDSP.
In addition, the existing 2002 General Plmr and Zoning classifications for the 120 acres currently allow
development of up to 360 residential units to be developed in this 120-acre area. Therefore, the revised
CCDSP Area proposes a total reduction of 458 units from the total be allowed by the adopted Specific Plan
and the existing General Plan and zoning designations for the 120-acre area proposed for addition to the
Specific Plan Area.
The 120-acre area to be added to the CCDSP Area was originally considered for inclusion in the adopted
CCDSP Area. However the land could not be acquired at that time, and was not included in the adopted
CCDSP Area. Because the 120-acre area was originally considered for inclusion in the adopted CCDSP
Area, the biological and cultural resources studies incorporated into the certified FIR address the
proposed expansion area. One exception is a 40-acre portion of the proposed additional 120-acres that
were not accessible for a physical reconnaissance when the cultural resource studies were prepared. A
physical reconnaissance was performed for the 40 acres in April 2004, and is discussed under the
Cultural Resources heading of this Addendum.

ENVIRONMENTAL ANALYSIS
LAND USE PLANNING & AGRICULTURE RESOURCES
Summary of Analysis in the Certified CCDSP Final EIR
The 988-acre project site was historically used for agricultural purposes, including crop production,
grazing, and horse farming. The majority of the site was fallow agricultural land, although
approximately 70 acres were used to grow grapes, sod, and dates. Approximately 100 acres in the eastern
half of the site were used for grazing, horse corrals, and stables at the time the EIR was prepared.
Sonoran desert scrub, the only native plant community on the project site, occupied 490 acres. The
remaining 318 acres were disturbed and include fallow or abandoned agricultural and pasture land as
well as a few abandoned structures, including at least one residential structure.
According to the 1992 City of La Quiuta General Plan EIR, prime agricultural soils were identified in the
southwestern, northeastern, and southeastern corners of the project site. At the time the EIR was
proposed, only 25 acres of the prime agricultural soils on the site had been recently used for agricultural
purposes, although these areas were basically fallow. In addition, the Agricultural Lands map of the La —
Quinta General Plan EIR identified Williamson Act parcels, labeled "SP 90-019 Agricultural Preserve — 72,"
along the southern portion of the project site. However, the Williamson Act contracts for these parcels
were scheduled to expire on January 1, 2000.
The proposed golf uses and 819 residential units were determined to be consistent with the existing
General Plan and Zoning Code designations for the site, and no impact with regard to General Plan and
Zoning Code designations would occur.
The 1992 General Plan Open Space Policy Diagram identified a conceptual location for a future park
facility within the project site along Avenue 54 between Jefferson Street and Madison Street. This park
was not included in the proposed project. Mitigation was adopted requiring payment of applicable
Quimby fees, reducing this potential impact to a less than significant level.
The original Specific Plan was determined to be consistent with all but one of the applicable policies from
the 1992 General Plan. The proposed Specific Plan was found to be inconsistent with Land Use Element
Policy 2-1.2.3, which requires that the front yard setbacks of all structures in areas subject to the Rural
Residential Overlay designation be increased beyond the minimum specified in the applicable zoning
district. The minimum front yard setback required by Section 5 of the Draft Specific Plan is 20 feet. As the
I pact Seim...., Inc. 12 Aodendnrn to thr
'°3-10 Counl.Y Club nttlrc Desrrt Sp,c /f c Plan Ftimt L1R
Drumm, 2004
Environmental Analysis
minimum required front yard setback in the corresponding zoning district is 30 feet, the Specific Plan was
not consistent with this policy. Mitigation was recommended requiring the applicant to revise the Specific
Plan to provide for front yard setbacks that are larger than the minimum required by the applicable
zoning for that portion of the site subject to the Rural Residential Overlay, reducing this potential impact
to a less than significant level.
The EIR identified that development of the proposed project would convert all of the prime agricultural
soils on the site, including the 25 acres most recently used for agriculture, to residential and golf course
uses. However, it was noted that the grapevines and date palms present on the site were relatively old,
not well maintained, and had reached the end of their productive lives. No feasible mitigation was
identified for the conversion of the prime agricultural soils. The City adopted a Statement of Overriding
Considerations for this unavoidable significant impact.
Analysis of Proposed Specific Plan Amendment
In 2002, the City of La Quinta updated its General Plan. The City of La Quinta Land Use and Zoning Map
designates the adopted CCDSP Area as Low-Densitv Residential, which allows up to 4 dwelling units per
acre (du/ac), and Golf Course Open Space. The adopted CCDSP allocates a maximum of 819 dwelling
units and an overall density of 0.83 du/ac. The current Land Use and Zoning Map designates the 120
acres proposed for addition to the CCDSP as Low -Density Residential with an Agricultural/Equestrian
Land Use and Rural Residential Zoning Overlay permitting zero to three du/ac, allowing development of
up to 360 dwelling units on this 120-acre site.
With the addition of the 120 acres to the CCDSP Area, this area would be subject to the requirements of
the CCDSP. The adopted CCDSP allows development of a total of 819 dwelling units. With the
development of the 446 units in The Hideaway and the 275 units proposed by the Specific Plan
Amendment, the overall number of residential units allowed within the enlarged CCDSP Area would be
721 units, which 98 fewer than are allowed by the adopted CCDSP. While the CCDSP Area would be
increased by 120 acres, the residential density within this enlarged CCDSP Area would less than and,
therefore, consistent with the density currently allowed in the CCDSP.
The proposed Specific Plan Amendment would be consistent with the existing General Plan and Zoning
Code designations for the site, and no impact with regard to General Plan and Zoning Code designations
would occur.

Environmental Analysis
The 2002 General Plan Open Space Policy Diagram no longer identifies a conceptual location for a future
park facility within the CCDSP Area along Avenue 54 between Jefferson Street and Madison Street.
Consistent with City policy, the Specific Plan Amendment project will be required to pay applicable
Quimby fees, reducing potential impacts to parks to a less than significant level.
Mitigation adopted for the Certified CCDSP Final EIR required that the Development Regulations of the
adopted CCDSP establish minimum front yard setbacks of 30 feet for houses with forward facing
garages. The adopted CCDSP does establish minimum front yard setbacks of 30 feet for houses with
forward facing garages. With implementation of mitigation measures for parks and front yard setbacks
adopted for the Certified CCDSP Final FIR, the adopted CCDSP is consistent with all of the applicable
policies in the 2002 General Plan. The 120 acres proposed for addition to the CCDSP Area will be
governed by the requirements of the CCDSP. Therefore, the proposed Specific Plan Amendment would
be consistent with all of the applicable policies from the 2002 General Plait.
The majority of the 120 acres proposed for inclusion as part of the CCDSP amendment are fallow
agricultural land and the remaining portions of the site are currenty used as grazing land. The
Department of Conservation currently designates the 120 acres as Prime Farmland and Farmland of Local
Importance on the 2002 State Important Farmland Maps. Approximately 40 acres within the 120-acre
area are also under Williamson Act contract. Notices of non -renewal have been filed and the current
contract will expire in 2012. However, contracts may be cancelled upon the mutual agreement of the
landowner and the local planning jurisdiction following the appropriate cancellation process. A request
for cancellation of a Williamson Act contract will be acted upon by the City as part of the development
approval process for the Specific Plan Amendment.
Development of the proposed project would convert all of the farmland on the site to residential and golf
course uses. The 2002 General Plan designates the 120 acres as Low -Density Residential with an
Agricultural/Equestrian Land Use and Rural Residential Zoning Overlay, thus, permitting residential
development. The CCDSP EIR identified the conversion of agricultural land to urban uses as an
unavoidable significant impact, and the City adopted a Statement of Overriding Considerations for it.
For these reasons, the conversion of an additional 120 acres by the proposed Specific Plan Amendment
will not result in any new or substantially more severe impacts to land use planning and agricultural
resources than those identified in the Certified CCDSP Final EIR.

Mitigation Measures
The following mitigation measure, identified in the Certified CCDSP Final FIR and adopted for the
CCDSP project, is applicable to the proposed Specific Plan Amendment project.

GEOTECHNICAL CONSIDERATIONS
Summary of Analysis in the Certified CCDSP Final FIR
The EIR determined that based on the results of the geotechnical evaluation of the site, development of
the proposed project was feasible from a geotechnical perspective. The site had the potential to
experience strong ground motions due to earthquakes on nearby active faults. There was a potential for
liquefaction and associated dynamic settlement, and the soils at the site had the potential for
hydroconsolidation with the addition of water, such as the results of substantial irrigation. This could
result in settlement of the soils on the site. Also, loose soils observed on the site had a potential for
settlement if subjected to structural loads and if left in their present condition. These loose surflcial soils
were also subject to wind erosion and transport. The EIR recommended mitigation measures to reduce
these potential impacts to less than significant levels.
Analysis of Proposed Specific Plan Amendment
Geotechnical impacts would be similar to those identified for the originally proposed project. Any
development on the site would be exposed to the same geologic hazards and is subject to current
building codes. The reduction in the total number of dwelling units will reduce the total number of
people potentially exposed to any geologic hazard. Based on this information, the proposed Specific Plan
Amendment would not result in any new or substantially more severe impacts with regard to
geotechnical considerations than those identified in the Certified CCDSP Final EIR.

Mitigation Measures
The following mitigation measures, identified in the Certified CCDSP Final FIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.
4.2-1. Prior to the design and construction of any structural improvements, the project developers shall
have comprehensive design level geotechnical evaluations conducted that include subsurface
exploration and laboratory testing. Recommendations for grading/earthwork, surface and
subsurface drainage, foundations, pavement structural sections, and other pertinent geotechnical
design considerations shall be formulated and implemented based on the findings of this
evaluation.
4.2-2. In order to safeguard against major seismic -related structural failures, all buildings within the
project site shall be constructed in conformance with the Uniform Building Code, as adopted by
the City of La Quinta.
4.2-3. The presence of liquefiable soils on the site shall be confirmed during the comprehensive design
level geotechnical evaluations identified in Mitigation Measure 4.2-1. If such soils are found on
the site, they shall be addressed by remedial grading, deep dynamic compaction, vibro-
compaction, stone columns, and/or mat or deep foundations to the specifications of a qualified
geotechnical engineer.
4.2-4. The potential for liquefaction and/or dynamic settlement of "dry sands" on the project site soils
shall be evaluated during the comprehensive design level geotechnical evaluations identified in
Mitigation Measure 4.2-1. If on -site soils have a potential for liquefaction and/or dynamic
settlement, they shall be addressed to the specifications of a qualified geotechnical engineer.
4.2-5. Loose surficial soils on the site shall be removed during site grading. Reuse of the soils as
compacted fill shall be pursuant to the specifications of a qualified geotechnical engineer.
4.2-6. The potential for hydroconsolidation of project site soils shall be determined during the
comprehensive design level geotechnical evaluations identified in Mitigation Measure 4.2-1. If
on -site soils have a potential for hydroconsolidation, they shall be addressed through remedial
grading, deep dynamic compaction, large-scale wetting of the subsurface soils, and/or other
means as specified a qualified geotechnical engineer.

4.2-8. The potential for lateral spreading on the project site with development shall be determined
during the comprehensive design level geotechnical evaluations identified in Mitigation
Measure 4.2-1. If on -site soils have a potential for lateral spreading, they shall be addressed to
the specifications of a qualified geotechnical engineer.
4.2-9. The potential for expansive soils (as defined in Table 18-1-B of the Uniform Building Code [19941)
on the project site shall be determined during the comprehensive design level geotechnical
evaluations identified in Mitigation Measure 4.2-1. If on -site soils have a potential for expansion,
they shall be addressed to the specifications of a qualified geotechnical engineer.
4.2-10. The potential for on -site subsidence during groundwater withdrawal shall be determined during
the comprehensive design level geotechnical evaluations identified in Mitigation Measure 4.2-1.

HYDROLOGY AND WATER QUALITY
Summary of Analysis in the Certified CCDSP Final EIR
The Coachella Valley Water District (CVWD) supplies potable water to the City of La Quinta. Water is
pumped from an underground aquifer beneath the City and treated for domestic use. The quality of
groundwater is variable at depths greater than 500 feet below the ground surface where the potable water
was withdrawn. Three groundwater wells were located on the site at the time the EIR was prepared;
water quality from these wells was expected to be relatively good.
The nearest surface water to the project site is the Coachella Canal, which carries water from the Imperial
Reservoir on the Colorado River, through the City, to Lake Cahuilla. This water has a higher mineral
content than the local groundwater supply and is not suitable for drinking without treatment. Instead, it
is primarily used for irrigation purposes, including golf course and agricultural irrigation.
The primary water quality concern during construction activities was excessive erosion and
sedimentation; however, other pollutants of concern included metals, nutrients, soil additives, pesticides,

construction chemicals, and miscellaneous wastes from construction sites. The FIR stated that demolition
of existing structures and properties on the project site could also indirectly introduce existing pollutants
into the ground or surface waters. Mitigation measures were recommended to reduce these impacts to a
less than significant level.
Potable water would be provided to the project by the CVWD. Water for irrigation would also be
provided to the project by the CVWD via the Coachella Canal. At the time the FIR was prepared, CVWD
staff indicated that adequate supplies of water could be provided to the project without impacting the
quality of surface or groundwater. Based on this information, impacts were determined to be less than
significant and no mitigation measures were required or recommended.
The control of local storm water drainage is under the jurisdiction of the City of La Quinta. As proposed,
runoff would be collected via private storm drains and conveyed to numerous, localized retention basins
within the project site. For the most part, these retention basins would be constructed in conjunction with
the golf course water features. Therefore, no increase in runoff to areas outside of the project site,
including the City storm drainage system, was expected from the project. Impacts were found to be less
than significant and no mitigation measures were required or recommended. —.
Water quality concerns associated with the proposed golf course and landscaped areas addressed in the
FIR related to the use of fertilizers, pesticides, and herbicides in these areas, and their entering protected
bodies of water, as well as the golf course ponds via stormwater and irrigation runoff. Due to the high
cost of water and the high cost of maintaining golf courses in southern California, modern golf course
design, construction, and management incorporates many features to minimize the use of fertilizers,
pesticides, and herbicides, as well as irrigation water runoff. Mitigation measures were recommended to
reduce this impact to a less than significant level.
It was expected that the man-made ponds on the site would be lined with either artificial or clay material
and that no infiltration of pond water into the groundwater basin would occur. This was common
practice in golf course design and construction in the project vicinity (i.e., PGA West). Impacts were
determined to be less than significant and no mitigation measures were required or recommended.
The FIR noted that non -point sources of pollutants may enter nearby water bodies via stormwater or wet
weather flows, or during dry weather flows. Mitigation measures were recommended to reduce this
potential impact to a less than significant level.

Environmental Analysis
Analysis of Proposed Specific Plan Amendment
Demand for groundwater in the Coachella Valley has annually exceeded the limited natural recharge of
the groundwater basin, which has created overdraft conditions. As the largest user of the groundwater
basin, the CVWD is responsible for the management and recharge of the groundwater basin. The CVWD
has adopted a management plan for the underground aquifer. As part of its implementation of the
management plan, the CVWD has, for example, entered into agreements with the State Water Project
(SWP) and the Metropolitan Water District (MWD) to import additional water to reduce overdraft
conditions. The City of La Quinta will continue to cooperate with the CWMD to ensure adequate water
supply for all uses in the Coachella Valley.
The reduction in the total number of residential units allowed by the Specific P1ali would reduce the
overall consumption of potable water, compared to the current CCDSP. The CVWD will provide
irrigation water for the golf course. The Coachella Valley aquifer has historically provided water for
irrigating golf courses in the Upper and Lower Valleys. However, in the future, golf courses in the City
of La Quinta will be required to irrigate landscaping with imported Coachella Canal water, consistent
with the CVWD management plan for the aquifer. Land uses allowed in the expanded CCDSP would
rely on imported canal water to irrigate the golf course and landscaping. The available canal allotment
will be apportioned between The Hideaway and Madison Creek in consultation with the CVWD.
As proposed, runoff would be collected via private storm drains and conveyed to numerous, localized
retention basins within the project site, as proposed in the original Specific Plan. For the most part, these
retention basins would be constructed in conjunction with the golf course water features.
Golf course design would be consistent with golf course design in The Hideaway portion of the CCDSP
Area. Mitigation measures recommended for the CCDSP project to minimize the impacts resulting from
runoff contamination and hazards would be applicable to the Specific Plan Amendment project.
Based on the above information, the proposed Specific Plan Amendment would not result in any new or
substantially more severe hydrology and water quality impacts than those identified in the Certified
CCDSP Final EIR.

Mitigation Measures
The following mitigation measures, identified in the Certified CCDSP Final EIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.
4.3-1. Prior to the initiation of any construction activity on the project site, the project developer shall
file for an NPDES permit from the RWQCB. A Notice of Intent (NOI), Storm Water Pollution
Prevention Plan (SWPPP), and Monitoring Plan are requirements of the NPDES permit. The
SWPPP shall include Best Management Practices (BMPs) in compliance with the NPDES program
requirements.
4.3-2. Prior to the initiation of any construction activity on the project site, the project developer shall
have a hazardous materials study or Phase I Environmental Site Assessment prepared for the site
to determine the presence of existing or prior storage and/or use of potentially hazardous
materials at the site. All recommendations of such a study shall be implemented to the
satisfaction of the RWQCB.
4.3-3. Anv existing groundwater wells located on the site that are no longer in use shall be abandoned
in accordance with federal, state, and local laws and regulations prior to the issuance of building
permits.

federal, state, and local laws and regulations prior to the issuance of building permits.
4.3-5. Prior to operation of the golf course, the golf course operator shall prepare a Golf Course
Management Plan that includes an irrigation plan, water usage plan, and chemical management
plan in order to reduce, to the extent feasible, golf course irrigation runoff and percolation into
the groundwater basin.
4.3-6. Design of new roads, golf courses, man-made ponds, common landscape areas, stormwater
basins, and other facilities shall incorporate proper engineering controls to channel storm and
irrigation runoff into detention/retention facilities that are sized to accommodate design year
storms and that incorporate filtration systems or other devices to reduce the potential for
herbicides, pesticides, fertilizers, and other contaminants to percolate to groundwater or surface —
water runoff.

BIOLOGICAL RESOURCES
Summary of Analysis in the Certified CCDSP Final EIR
The EIR identified four vegetation communities occurring on the CCDSP project site: Sonoran desert
scrub, pasture, agricultural, and disturbed vegetation. Sonoran desert scrub, the only native plant
community on the project site, occupied 490 acres of the 988-acre site. A component of this community,
mesquite hummocks, occupied 25 of those 490 acres. Agricultural areas occupied 70 acres of the site.
Crops planted on this acreage included grapes, sod and dates. Grazed pasture encompassed 110 acres of
the site. The remaining 318 acres were disturbed habitat and contained fallow or abandoned agricultural
and pasture land as well as residences. The vegetation communities present on the project site provided
habitat for a variety of common wildlife species.
No areas under the jurisdiction of the ACOE or the CDFG were present within the project site, and the
project site did not act as linkage between large open spaces and, for this reason, did not serve as a
movement corridor for wildlife.
The EIR determined that the original CCDSP project would directly affect the entire site, resulting in the
conversion of 490 acres of Sonoran desert scrub, 110 acres of irrigated pasture, 70 acres of agricultural
land and 318 acres of disturbed habitat to residential and golf course uses.
A number of common and special -status bird species (particularly raptors) were identified as potentially
being affected as a result of construction or other site -preparation activities. Such activities could result in
the direct loss of active nests or the abandonment of active nests by adult birds. Bird nests with eggs or
young are protected under the Migratory Bird Treaty Act and the California Fish and Game Code.
Portions of the project site constituted suitable habitat for the Coachella Valley milk -vetch, a federally
listed Endangered species, but no occurrences of this plant were found on the site.
The Specific Plan as originally proposed was identified as impacting approximately 25 acres of mesquite
hummocks, a distinct component of the Sonoran desert scrub habitat occurring on the original CCDSP
site. This vegetation community was considered "Threatened" by the California Department of Fish and
Game and was recognized by the 1992 City of La Quinta General Plan as second only to wash habitats in
significance and general habitat value within the City. Mesquite hummocks are also known to provide
suitable habitat for the Coachella Valley milk -vetch, an Endangered plant species. Based on this
information, the loss of 25 acres of this community was identified as a significant impact.

Environmental Analysis
The original CCDSP project was not expected to impact the flat -tailed horned lizard, Coachella Valley
fringe -toed lizard, Palm Springs pocket mouse, and Palm Springs (Coachella Valley) round -tailed ground
squirrel since surveys for these species were negative. The project was not expected to reduce regional
populations of Coachella Valley grasshopper, and no suitable habitat for the Coachella giant sand treader
cricket was present on site.
The EIR identified that development of the original CCDSP project would increase the extent of nighttime
light and glare on the natural areas surrounding the proposed project. Nighttime light can disturb
breeding and foraging behavior and can potentially alter breeding cycles of birds, mammals and reptiles.
However, the project would be subject to the City's "Dark Sky' Ordinance which required that light
standards within parking lots, and exterior lights on buildings be directed downward and appropriately
shielded to prevent light spillage and glare to adjacent properties. With these controls, the potential
impacts associated with light and glare were not expected to be significant.
Implementation of the recommended mitigation measures reduced the potential direct project -related
impacts on plant communities, special -status plants, and common and special -status bird nests to less
than significant levels. —
Implementation of recommended mitigation would reduce the project -related impacts of the project on
mesquite hummock habitat to a less than significant level. However, the loss of 25 acres of mesquite
hummocks combined with that associated with ongoing development in the area represented a net
cumulative loss of mesquite hummock habitat that could not be mitigated to a less than significant level.
The City adopted a Statement of Overriding Considerations for this cumulative unavoidable significant
impact.
Analysis of Proposed Specific Plan Amendment
The 120-acre area to be added to the CCDSP Area was originally considered for inclusion in the CCDSP
Area and, for this reason, the biological resources studies incorporated into the certified EIR address the
proposed expansion area. In addition, an Impact Sciences biologist visited the 120-acre site in November
2004 and performed a field reconnaissance survey to verify conditions have not changed substantially
since the original surveys were completed.
The four vegetation communities present within the original CCDSP Area also occur on the Specific Plan
Amendment project site: Sonoran desert scrub, pasture, agricultural, and disturbed vegetation.
Approximately 10 acres of mesquite hummocks are present on the 120-acre site proposed for addition to

the CCDSP Area; an approximately 9-acre stand is located near the northeast corner of the site, and an
approximately 1-acre stand is located near the west side of the site. The field reconnaissance determined
that no burrowing owls are present on the 120-acre site.
The 2002 General Plan exhibits do not indicate the potential distribution of any species of concern on the
proposed project site with one exception; as shown in 2002 General Plan Exhibit 6.5, Palm Springs Ground
Squirrel, the Palm Springs round tailed ground squirrel (also called the Coachella Valley round tailed
ground squirrel) (Spec mophihis tereticaudus clilonts) has the potential to be present on the project site. The
project site, inclusive of the 120 acres proposed for addition to the Specific Plarr, was surveyed for this
species as part of the biological resources studies incorporated into the certified EIR. No Palm Springs
round -tailed ground squirrels were observed or detected, and the potential for this species to occur
within the project site is considered low for this reason.
The U.S. Fish and Wildlife Service proposed a rule on December 14, 2004, to designate critical habitat for
the federally Endangered Coachella Valley milk -vetch. Neither the adopted CCDSP Area nor proposed
amended CCDSP are within the proposed designated area.I
The EIR prepared for the originally proposed CCDSP project identified the net cumulative loss of
mesquite hummock habitat as an unavoidable significant impact and adopted a Statement of Overriding
Considerations for the impact. The conversion of an additional 10 acres of mesquite hummock by the
proposed Specific Plan Amendment is not considered to result in any new or substantially more severe
impacts to biological resources than those identified in the Certified CCDSP Final EIR.
Based on the information above, the proposed Specific Plan Amendment would not result in any new or
substantially more severe impacts to biological resources than those identified in the Certified CCDSP
Final EIR.

Mitigation Measures
The following mitigation measures, identified in the Certified CCDSP Final FIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.
4.4-1. The project developer shall implement the following program if site grading and/or construction
will occur during the nesting/breeding season (typically February through July) of native bird
species potentially nesting on the site:
Prior to construction or site -preparation activities, a field survev shall be conducted by a qualified
biologist to determine if active nests of special -status birds (e.g., loggerhead shrike) or common
bird species protected by the Migratory Bird Treaty Act and/or the California Fish and Game
Code, are present in the construction zone or within 50 feet of the construction zone. If active
nests are found, a minimum 50-foot (this distance may be greater depending on the bird species
and construction activity, as determined by the biologist) fenced buffer shall be established
around the nest site. No construction activities will be permitted within this nest zone until the
young birds have fledged, as determined by the project biologist.
4.4-2. Prior to construction or site preparation activities, the project developer shall enter into a
Memorandum Of Understanding (MOU) with CDFG and an appropriate non-profit organization
whose purpose is to acquire and manage land for the purpose of protecting special status plants
and wildlife. This MOU shall provide the organization chosen the financial resources necessary
to purchase and manage 25 acres of mesquite hummock habitat in the Willow Hole area where
the habitat is contiguous and large preserves already protect much of this habitat type. The exact
location and cost shall be determined through consultation with CDFG and the selected
organization. CDFG has indicated that sufficient mesquite hummock habitat is available for
acquisition and preservation. Because Coachella Valley milk -vetch can occur with mesquite
hummocks, the acquisition and preservation of mesquite hummock habitat is also proposed to
mitigate for the loss of habitat on the site that may be suitable for the milk -vetch.
CULTURAL RESOURCES
Summary of Analysis in the Certified CCDSP Final FIR
A Phase I Cultural Resource Investigation (September 1, 1999) and a Phase II Cultural Resources Testing
Program (June 7, 2000) were prepared for the CCDSP project site and included in the Certified EIR.
Preparation of each report involved an archaeological records check, historic background research,

Native American consultation, archaeological field surveys/testing, and analysis of the data compiled. In
August of 2000, an addendum to the previous studies was prepared in order to assess 200 acres of land
not previously accessible. The reports and the addendum are provided in Appendix 4.5 of the Draft EIR
prepared for the original CCDSP project. The two cultural resource reports assessed 1,300 acres of land
rather than the 988 acres proposed for the CCDSP site. This was because the cultural resource analyses
were initiated when the applicant was considering a larger project than the 988-acre CCDSP Area as
finally approved. Nonetheless, the two reports covered the entire site of the proposed Specific Plan Area
as well as two areas totaling 80 acres beyond the Specific Plan limits.
During the preparation of the Phase I cultural resource investigation, 43 isolated finds and six prehistoric
archaeological sites were identified within the study area. Thirty-five of these isolates were located
within the current project boundary. In addition, five previously recorded sites were identified within
the project site. Five residential complexes were also identified as having potential historic origin. It was
concluded that additional analysis in the form of Phase II subsurface testing be conducted on the six sites
and a historical evaluation be conducted on the residential complexes to determine their significance.
Phase II testing determined all of these sites to be insignificant and, therefore, not eligible for listing on
the national Register of Historic Places nor the California Historical Landmark listing. As a result,
development of the originally proposed CCDSP project was determined not to significantly impact any
cultural resources located within the project site.
The FIR identified a potential for unidentified subsurface components within or near the identified sites
to be located during future ground altering activities, including demolition of the existing modern
structures and facilities. Mitigation measures were recommended to reduce these potential impacts to
less than significant levels.
Analysis of Proposed Specific Plan Amendment
The Specific Plan Amendment proposes to add 120 acres to the adopted CCDSP Area. As noted above,
the two cultural resource reports assessed 1,300 acres of land rather than the 988 proposed for the CCDSP
site, including 80 acres of the 120 acres proposed for addition to the Specific Plan Area. A Phase I
Cultural Resource Investigation was prepared in April 2004 for the 40 acres not addressed by the original
surveys. This report is provided in Appendix A of this Addendum. Preparation of the report involved a
historical/archaeological research records check, historical background research, and an intensive -level
field survey. No previously recorded sites were located in the immediate vicinity of the 40-acre area
surveyed. A residential building dating to circa 1954, trailers, the remains of horse corrals, standpipes, an
irrigation system, and trash were identified within the 40-acre area surveyed. This building was

determined not to meet the definition of a "historical" resource as provided in CEQA, or the criteria for
inclusion in the City's historic resources inventory per the City's ordinance. As a result of studies
prepared for the CCDSP project and the Specific Plan Amendment, development of the proposed Specific
Plan Amendment Area is not expected to significantly impact any cultural resources located within the
project site. However, there is always a potential for unidentified subsurface components during future
ground altering activities, including demolition of the existing structures. This is a potentially significant
impact; however, mitigation recommended for the proposed Specific Plan Amendment and mitigation
adopted for the Certified CCDSP Final EIR would reduce this potential impact to below a level of
significance.
A paleontological records search by the Natural History Museum of Los Angeles County was conducted
for the CCDSP Area east of Madison Street and for the 120 acres proposed as part of the Specific Plan
Amendment. The letter from the Natural History Museum is provided in Appendix A.
Surface deposits in the proposed Specific Plan Amendment Area are composed of soil and younger
Quaternary Alluvium that are unlikely to contain significant vertebrate fossils, at least in the uppermost
lavers, and there are no localities anywhere nearbv from these surface deposits. The proposed Specific
Plan Amendment Area lies just east of the exposures of Quaternary deposits of the ancient Lake Cahuilla
and just west of high shoreline of the ancient Lake Cahuilla. The entire proposed Specific Plan
Amendment Area probable will have subsurface lacustrine and fluvial (lake and stream channel)
deposits of Late Pleistocene or Holocene age known as the Lake Cahuilla beds. Several fossil localities
are present in the Lake Cahuilla beds south of the Specific Plan Amendment Area on both sides of
Madison Street north of 58th Avenue. Collections from these localities produced a significant fauna of
terrestrial and freshwater vertebrates as well as diatoms, land plants, clams, snails, and crustaceans. A
nearby locality produced a single jaw of the bighorn sheep. Subsurface excavation below the uppermost
layers of soil and younger Quaternary Alluvium may well encounter significant fossil remains from the
Quaternary Lake Cahuilla beds. According to the 2002 General Plan, Exhibit 6.8, Paleontological
Sensitivity Map, much of the City of La Quinta, including the project site, lies within the historic beds of
Lake Cahuilla. The City requires monitoring for paleontologic resources during earth -moving activities,
and will condition the project to monitor for paleontology resources during earth -moving activities. With
this condition, potentially significant impacts to paleontological resources are reduced to a less than
significant level.
Based on the information above, the proposed Specific Plan Amendment would not result in any new or
substantially more severe impacts to cultural resources than those identified in the Certified CCDSP Final
EIR.

TRAFFIC AND CIRCULATION
Summary of Analysis in the Certified CCDSP Final EIR
City policies stated Level of Service (LOS) D was acceptable at the intersections within La Quinta. At the
time the EIR was prepared, under existing conditions, the 10 study area intersections operated at LOS C
or better during the peak traffic hours. At the time the EIR was prepared, traffic signals were warranted
at two of the study intersections, and improvements to these intersections were under way as part of the
City's Jefferson Street Improvement Project.
The CCDSP project was projected to generate a total of approximately 9,690 trip -ends per day, with 731
vehicles per hour during the A.M. peak hour and 965 vehicles per hour during the P.M. peak hour.
Under future 2005 conditions with the CCDSP project, two study intersections were projected to operate
at unacceptable levels of service during the peak hours with the proposed project and no roadway or
intersection improvements. Therefore, the addition of project -generated traffic was projected to cause a
significant impact under that scenario, without mitigation. With the development of intersection

peak hours and potentially significant traffic and circulation impacts were reduced to less than significant
levels.
At General Plan buildout with the CCDSP project, all of the study area intersections were projected to
operate at unacceptable levels of service with the proposed project and no roadway or intersection
improvements without mitigation. With the development of the intersection improvements to be funded
by the City's Development Impact Fee, and other improvements to be made by individual development
projects, all of the study area intersections were projected to operate at LOS D or better during the peak
hours and potentially significant traffic and circulation impacts were reduced to less than significant
levels.
Analysis of Proposed Specific Plan Amendment
A traffic study to evaluate traffic generation that would occur as a result of uses that would be allowed by
the proposed Specific Plan Amendment was prepared, and is provided in Appendix B of this
Addendum. Seven intersections were studied, including four that were studied for the originally
proposed CCDSP project. The uses that would be allowed by the Specific Plan Amendment are estimated
to generate a total of approximately 3,275 trip -ends per day, with 246 vehicles per hour during the A.M.
peak hour and 328 vehicles per hour during the P.M. peak hour. As noted above, the overall number of
residential units allowed within the enlarged CCDSP Area would be 98 fewer units than are allowed by
the adopted CCDSP. Therefore, traffic generation would be reduced, and the resulting traffic impacts
would be lessened, when compared to the current Specific Plan.
For future 2009 conditions with the proposed Specific Plan Amendment project, one intersection would
operate at LOS D or better during the peak hours, and six intersections would operate at Level of Service
E or F during peak hours without mitigation. Implementation of the improvements recommended below
for site circulation and access would ensure that all of the study area intersections would operate at LOS
D or better during the peak hours.
Recommended improvements for site circulation and access for the area east of Madison Street include:
1. Construct Avenue 52 from Madison Street to the easterly Specific Plan Amendment project
boundary at its ultimate half -section as a Primary Roadway -A in conjunction with the Specific
Plan Amendment project development.
2. Construct Monroe Street from Avenue 54 to the project boundary at its ultimate half -section as a —
Primary Roadway -A in conjunction with the Specific Plan Amendment project development.

3. Construct Madison Street from Avenue 54 to Avenue 52 at its ultimate half -section as a Primary
Roadway -A in conjunction with the Specific Plan Amendment project development.
4. Construct Avenue 54 from Madison Street to Monroe Street at its ultimate half -section as a
Secondary Roadway in conjunction with the Specific Plan Amendment project development.
5. Construct a traffic signal at the intersection of the Specific Plan Amendment project northerly
access and Avenue 52, when warranted.
In addition, the project would be required to pay fees for its fair share of improvements at those
intersections where traffic signals are warranted. With implementation of the recommended site
circulation and access improvements and payment of fees, potentially significant traffic and circulation
impacts would be reduced to less than significant levels.
The Specific Plan Amendment proposes to allow 98 fewer dwelling units than are allowed in the adopted
CCDSP. The 2002 General Plena and Zoning classifications for the 120 acres currently allow development
of up to 360 residential units within the 120-acre area proposed for addition to the Specific Plan Area.
Therefore, the amended CCDSP Area proposes a total reduction of 458 units from what would be
allowed by the adopted Specific Plan in combination with that allowed in the 120 acres proposed for
addition to the Specific Plan. The proposed Specific Plan Amendment Project would reduce residential
development, which would reduce traffic generation, compared to the current General Plan. Also, with
mitigation, all of the study intersections would operate at acceptable Levels of Service. Based on this
information, the proposed Specific Plan Amendment would not result in any new or substantially more
severe traffic and circulation impacts than those identified in the Certified CCDSP Final EIR.
Mitigation Measures
The following mitigation measures, identified in the Certified CCDSP Final EIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.
4.6-7. Prior to the approval of final grading, landscaping, and street improvement plans, the project
developer shall submit plans that demonstrate that the sight distance of each project entrance
meet City of La Quinta and Caltrans sight distance standards.
4.6-8. The project developer shall submit traffic signing/striping plans in conjunction with detailed
construction plans for the project site.
4.6-9. The project developer shall contribute towards a citywide roadway and traffic signal
improvement program through the payment of required Infrastructure Development Fees. These

fees will be paid at the building permit stage of development. The project developer shall be
solely responsible for new traffic signals at all project entrances, when warranted.
AIR QUALITY
Summary of Analysis in the Certified CCDSP Final EIR
Implementation of the original CCDSP project was projected to generate both construction -related and
operation -related pollutant emissions. Construction -related emissions were projected to be generated by
on -site stationary sources, heavy-duty construction vehicles, construction worker vehicles and energy
use. During the site preparation phase, emissions of particulate matter (10 micron) (PM,,,) were projected
to exceed thresholds of significance adopted by the South Coast Air Quality Management District
(SCAQMD). During the construction phase, emissions of volatile organic compounds (VOC) were
projected to exceed thresholds of significance adopted by the SCAQMD. This was a result of emissions
associated with the application of architectural coatings. However, it was assumed that architectural
coatings would comply with SCAQMD Rule 1113 for such materials. Emissions of carbon monoxide
(CO), nitrogen oxide (NO,) and SO, were not projected to exceed the recommended thresholds during
site preparation and construction, and were not considered significant. —
The EIR indicated that operation -related emissions would be generated by on -site and off -site stationary
sources and by mobile sources. At buildout, operational emissions of PM,,, VOC, and NO, were
projected to exceed the City's thresholds. Localized CO levels near intersections were projected to be
well below state and tederal standards. Localized emissions could also be generated by the clubhouse
which may include a restaurant and beauty salon. Local emissions from these or similar uses were
required to comply with SCAQMD Regulation XIII. The project's emissions were, however, considered
to be consistent with those projected in the AQMP and the EIR indicated that the project should not
jeopardize attainment of state and federal ambient air quality standards in the Coachella Valley. In
addition, the project was determined to meet the SCAQMD's assumption for a one percent reduction in
annual emissions for new projects. Nonetheless, operational emissions of PM,,1, VOC, and oxides of
nitrogen NO, were considered significant.
The population growth attributed to the CCDSP project was included within the Coachella Valley
Association of Governments growth forecasts that formed the basis for the land use and transportation
control portions of the Air Quality Management Plan (AQMP). Because the original CCDSP project was
within the AQMP growth forecasts for the City, it was considered to be consistent with the AQMP, which
ImpaY Scientc, Lr.. 30 Addcndan. to thr
113_70 Cometni Cho of thr Drsert Spt cd,, PI,u Final LR
Drrudcr]00d
Environinenta i Analysis
indicated that approval and implementation of the project would not jeopardize attainment of state and
federal ambient air quality standards in Riverside County.
While the mitigation measures recommended in the EIR were projected to reduce the construction and
operational air emissions the original CCDSP project was expected to generate to the greatest extent
feasible, the construction and operation air quality impacts of the project were considered to remain
significant. The City adopted a Statement of Overriding Considerations for this unavoidable significant
impact.
Analysis of Proposed Project
Since the EIR was prepared, the SCAQMD has adopted a plan to address PM,„ emissions in the Coachella
Valley. In 1999 the annual average for PM,,, concentrations had risen significantly. As mandated by the
Environmental Protection Agency (EPA), each air district was required to maintain PM,,, standards
through 2001. The SCAQMD was not going to meet this requirement in the Coachella Valley, and the
2003 Coachella Vallee State Implementation Plan was prepared outlining new methods aimed at
attaining the PM,, standard, as well as requesting an extension to the 2001 EPA deadline for PM,,,
attainment. The City will condition the project to comply with these updated standards and methods.
With regard to PM,,, emissions generated from grading activities, construction activities are required to
comply with SCAQMD Rules 403 - Fugitive Dust, and Rule 403.1 - Supplemental Fugitive Dust Control
Requirements for Coachella Valley Sources, as amended in April 2004, Both SCAQMD Rules require the
use of stringent best available control measures to minimize the PM,,, emissions during grading and
construction activities. The City will condition the project to comply with these updated requirements.
The proposed Specific Plan Amendment project would result in grading and construction activities
occurring on an additional 120 acres. At the same time, additional mitigation measures to reduce PM,,
emissions have been identified and would be required. Therefore, construction impacts would be similar
to those of the original CCDSP project evaluated in the EIR. During the site preparation phase, emissions
of PM,,, are projected to exceed thresholds of significance adopted by the SCAQMD. During the
construction phase, emissions of VOC would exceed thresholds of significance adopted by the SCAQMD.
The overall number of residential units allowed within the enlarged CCDSP Area by the Specific Plan
Amendment project would be 98 fewer units than are allowed by the adopted CCDSP. Nonetheless, even
with the reduced density proposed by the Specific Plan Amendment at project buildout, operational
emissions of PM,,,, VOC, and NO, would exceed the City's thresholds. While the recommended

mitigation measures would reduce the air emissions the project would generate to the greatest extent
feasible, the air quality impacts of the project would remain significant even with reduced density.
The mitigation measures identified in the Certified CCDSP Final EIR and adopted for the CCDSP project
and recommended for the Specific Plan Amendment project would reduce the construction and
operational air emissions the Specific Plan Amendment project would generate to the greatest extent
feasible. Nonetheless, the construction and operational air quality impacts of the Specific Plan would
remain significant with the proposed amendment. The City adopted a Statement of Overriding
Considerations for this unavoidable significant impact. Thus, the proposed Specific Plan Amendment
would not result in any new or substantially more severe air quality impacts than those identified in the
Certified CCDSP Final EIR.
Mitigation Measures
The following mitigation measures, identified in the Certified CCDSP Final EIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.

Environmental Analysis
existing and future on- and off -site mobile source noise involved the calculation of existing and future
vehicular noise levels along individual roadway segments in the vicinity of the project site
Noise levels generated during the construction phase were projected to primarily affect the occupants of
nearby residential uses immediately to the south of Avenue 54. Construction activities would be
restricted on a daily basis in accordance with the La Quinta Municipal Code. Even with implementation
of all feasible mitigation measures to reduce construction noise, it was anticipated that construction noise
would result in temporary impacts at the nearest residences.
Noise levels adjacent to on -site residences along evaluated roadways within the proposed CCDSP Area
were not projected to exceed City of La Quinta Noise Standards for Land Use Compatibility under
General Plan buildout conditions. The increase in noise levels attributable to project -generated traffic at
off -site locations was not expected to exceed thresholds. Future noise levels at the residential units on the
project site were projected to be below the City's 60 dB(A) CNEL standard. Operational impacts, both on
and off site, were determined to be less than significant, and no mitigation measures were required or
recommended.
Golf course tournaments held at PGA West were projected to generate additional mobile and stationary
source noise impacts in the project area. At the time the FIR was prepared, these tournaments typically
occurred once per year, lasted approximately one week, and typically included traffic management
strategies to direct traffic and keep it flowing freely along area roadways. This did not, however,
preclude the possibility of short-term mobile and stationary source noise impacts on noise sensitive uses
on the project site that may occur close to one of these roadways. Mitigation was recommended to reduce
this potential impact to a less than significant level.
A Statement of Overriding Considerations was adopted by the City for the unavoidable construction
noise impacts identified for the project.
Analysis of Proposed Specific Plan Amendment
Short-term construction impacts would be similar to those associated with the development of the
residential and golf uses proposed in the CCDSP project examined in the 2000 Final EIR. The proposed
Specific Plan Amendment project would mean that grading and construction activities would occur on an
additional 120 acres. At the same time, fewer homes would be constructed. Noise levels generated
during the construction phase would primarily affect the occupants of nearby residential uses
immediately to the south of Avenue 54 and those residences in the residential community in the process

of being approved for development at the southwest corner of Monroe Street and Avenue 52, adjacent to
the northeast corner of the CCDSP Area. Construction activities would be restricted on a daily basis in
accordance with the La Quinta Municipal Code. Even with implementation of all feasible mitigation
measures to reduce construction noise, it is anticipated that construction noise will result in temporary
impacts at the nearest residences.
The Specific Plan Amendment proposes to allow 98 fewer dwelling units than are allowed in the adopted
CCDSP. The 2002 General Plan and Zoning classifications for the 120 acres currently allow development
of up to 360 residential units to be developed in the 120-acre area proposed for addition to the Specific
Plan Area. Therefore, the amended CCDSP Area proposes a total reduction of 458 units from what
would be allowed by the adopted Specific Plan in combination with that allowed in the 120 acres
proposed for addition to the Specific Plan. Noise from traffic, both on and off site, would be reduced as a
direct result of the reduction in traffic generation, and operational noise impacts would remain less than
significant. As the overall development intensity has decreased, the operational noise resulting from the
project would also decrease from that which was identified in the original documentation.
Mitigation adopted to reduce potential noise impacts from golf course tournaments held at PGA West to —
less than significant levels would be applicable to the proposed Specific Plan Amendment.
As noted above, a Statement of Overriding Considerations was adopted by the City for the unavoidable
construction noise impacts. Based on the above information, the proposed Specific Plan Amendment
would not result in any new or substantially more severe noise impacts than those identified in the
Certified CCDSP Final FIR.
Mitigation Measures
The following mitigation measures, identified in the Certified CCDSP Final FIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.
4.8-1. Between May 1 and September 30, all construction activities on the project site shall only occur
between the hours of 6:00 A.M. and 7:00 P.M. Monday through Friday, and from 8:00 A.M. to
5:00 P.M. on Saturday, and shall be prohibited on Sundays and public holidays. Between
October 1 and April 30, all construction activity on the project site shall only occur between the

PUBLIC SERVICES
Summary of Analysis in the Certified CCDSP Final EIR
Public Parks
With the exception of Lake Cahuilla County Park, the City of La Quinta is responsible for providing and
maintaining public parks within the City.
Using the City's 3.0 acres of park land per 1,000 population standard, the original CCDSP project was
projected to generate the need for approximately 7.9 acres of new Neighborhood and Community Park
land. The Open Space Policy Diagram of the 1992 City of La Quinta General Plan identified a conceptual
location for a future park facility within the project site along Avenue 54 between Jefferson Street and
Madison Street. This park facility was not proposed as part of the Specific Plan.
The Specific Plan stated that the project developers would pay Quimby Act in -lieu fees to the City as
required by the Nexus Fee Ordinance established for parks. These fees would be used to rehabilitate
existing or develop new Neighborhood Park, Community Park, or recreational facilities within the
service area of the most proximate existing or future Neighborhood or Community Park. Payment of the
fees would mitigate the impact of the CCDSP project to a less than significant level.

Fire Protection and Paramedic Services
Fire protection services are provided to the City of La Quinta under contract with the Riverside County
Fire Department. Fire Stations 32 and 70 provided first alarm and secondary response service to the
vicinity of the proposed project site. Both of these stations had average response times of five minutes or
less.
Project development was identified as increasing the demand for services by the Riverside County Fire
Department. Construction sites would be subject to Coachella Valley Water District and Riverside
County Fire Department standards relative to water availability and fire department fire fighting
equipment accessibility standards. Adherence to County and City codes and requirements during
construction were expected to reduce the potential for fire hazards at the project site during construction
to a less than significant level. According to the fire department, no additional fire department resources
would be needed to address the project's fire prevention and fire suppression needs; compliance with
standard project design and construction requirements would avoid potentially significant impacts.
Mitigation measures were recommended to reduce the potential for fire -related hazards at the site.
Paramedic services are provided in La Quinta by Springs Ambulance Service, which operated from
County Fire Station 70 on Madison Street. The FIR indicated that the proposed project could also
increase the demand for paramedic services due to the increased human activity at the site. However,
paramedic response times and service were adequate in the project area and were projected to remain so
with the project.
Based on this analysis, the FIR stated that the proposed project would not increase the demand for service
beyond the ability of the fire department and Springs Ambulance Service to provide timely and adequate
service to emergency calls and would not prevent the fire department and ambulance service from
providing adequate service to the rest of their service areas. Therefore, the project's potential impacts
were not considered significant.
Police Protection Services
Police protection services are provided to the City of La Quinta under contract by the Riverside County
Sheriff's Department. The City of Quinta and other areas of the eastern Coachella Valley are served by
the department's station located at 82-695 Dr. Carreon Boulevard, in Indio. At the time the FIR was
prepared, Sheriff's patrol deputies provided emergency response times of approximately five minutes
throughout the City.

Environmental Analysis
Project development was projected to increase the demand for services by the Riverside County Sheriff's
Department. The entire site was proposed to be gated, which was expected to minimize the potential for
criminal activity within the project site. The sheriff's department anticipated that there would be minimal
calls for service to the project site and that they could accommodate this increase in the number of service
calls without any significant impact to their present levels of service. The increase in population was
determined to result in increased demand for police protection services within the City and surrounding
vicinity. Using the City's planning standard of 1.5 deputies per 1,000 population, the proposed project
was projected to generate the need for four additional officers patrolling the City. Compliance with the
department's recommendations for crime prevention through project design were determined to increase
project security to an acceptable level. Mitigation measures were recommended to reduce the calls for
service to the site.
Public Schools
Public education services are provided to the project site and the areas of the City east of Jefferson Street
by the Coachella Valley Unified School District (CVUSD). None of the 15 schools administered by the
CVUSD are located within the City of La Quinta; the nearest schools are located in the City of Indio.
Overall, at the time the FIR was prepared, the CVUSD served 12,154 students and had a district -wide
permanent capacity for 8,961 students. As such, the CVUSD was overenrolled by 3,193 students at the
time the FIR was prepared.
Based on the student generation factors used by the Coachella Valley Unified School District (CVUSD),
the proposed 819 residential units were projected to generate up to approximately 549 elementary school
students, 147 middle school students, and 328 high school students. Since the permanent capacity of the
facilities was exceeded at the time the FIR was prepared, the potential generation of this many additional
students was considered a significant impact. Mitigation requiring the payment of developer fees was
recommended to reduce the direct impacts of the project to less than significant levels.
Analysis of Proposed Specific Plan Amendment
Public Parks
As a result of the reduced residential density proposed by the Specific Plan Amendment, demands for
park facilities would be reduced when compared to the currently proposed Specific Plan. Payment of
Quimby Act in -lieu fees would mitigate the impacts of the project to less than significant levels.

Environmental Analysis
Therefore, the proposed Specific Plan Amendment would not result in any new or substantially more
severe impacts to public parks than those identified in the Certified CCDSP Final FIR.
Fire Protection and Paramedic Services
As a result of the reduced residential density proposed by the Specific Plan Amendment, demands for
fire protection and paramedic services would be reduced when compared to the currently proposed
Specific Plan. In addition, a new Fire Station, Fire Station 93, located at 44-555 Adams Street in La Quinta,
is now operational in the northern area of the City. Therefore, the proposed Specific Plan Amendment
would not result in any new or substantially more severe impacts to fire protection and paramedic
services than those identified in the Certified CCDSP Final FIR.
Police Protection Services
As a result of the reduced residential density proposed by the Specific Plan Amendment, demands for
police services would be reduced when compared to the currently proposed Specific Plan. In addition, a
Riverside County Sheriff's Department substation, the Community Oriented Policing Office, located at
51351 Avenida Bermudas in La Quinta, is now operational. Therefore, the proposed Specific Plan
Amendment would not result in anv new or substantially more severe impacts to police protection
services than those identified in the Certified CCDSP Final FIR.
Public Schools
It is anticipated that buyers of the residences in the Specific Plan Amendment Area would be similar to
those purchasing residences at The Hideaway. Residences at The Hideaway have primarily been
purchased by active retirees or by families who spend weekends and holidays at the residences, but are
not permanent residents.2 As of November 2004, no students that would potentially attend CVUSD
schools reside at The Hideaway.'
The Specific Plan Amendment proposes 98 fewer dwelling units than were projected in the Certified
CCDSP Final EIR, which would be expected to lead to a reduction in the number of students projected in
the Final EIR. As noted above, thus far, development of the adopted Specific Plan project has not
generated any students. Based on the assumption that the residents in the proposed Specific Plan
Amendment project would be similar to residents in The Hideaway, student generation is expected to be

Summary of Analysis in the Certified CCDSP Final EIR
Water Supply and Distribution
The EIR stated that potable water would be provided to the original CCDSP project by the CVWD
through a system of wells, reservoirs, and water transmission lines. The originally proposed Specific Plan
stated that a series of 18-inch water lines would be installed in Avenue 52, Avenue 54, and Monroe Street
as part of the project. In addition, the existing 12-inch water line located in Jefferson Street was proposed
to be upsized to 18 inches. Two domestic water pressure zones were located within the CCDSP project
site. Therefore, the actual water improvements required for the project would be determined based upon
a review of the final site plan by the CVWD, including the CVWD's domestic water unit. The water
transmission and distribution lines would be required to be funded and installed by the project
developers subject to the CVWD's approval.

Environmental Analysis
Water for irrigation of the golf course and landscape setbacks would be obtained from the Coachella
Canal. At the time the EIR was prepared, there were existing irrigation delivery laterals within the
project site that would need to be replaced or relocated to serve the project. These irrigation laterals were
owned by the Bureau of Reclamation and were operated by the CVWD.
During the construction phases of development, non -potable water would be used to suppress dust
generated by earthmoving activities, the operation of vehicles on dirt surfaces, and exposed dirt surfaces.
This water would be obtained from the Coachella Canal. At the time the EIR was prepared, CVWD staff
indicated that the existing non -potable water supplies were adequate to serve the proposed project
during construction without causing any significant impacts.
The potable water demand of the proposed project was estimated to be approximately 479 acre-feet per
year. Demand for non -potable irrigation water was estimated to be 5,250 acre-feet per year. At the time
the EIR was prepared, CVWD staff indicated that the existing potable and non -potable water supplies
were adequate to serve the proposed project during operation without causing any significant impacts.
However, the CVWD indicated that specific water conservation measures for both landscaping and
irrigation and plumbing controls may be identified and placed as conditions on the connection of the
project to the CVWD's facilities. Mitigation measures were recommended to reduce this impact to a less
than significant level.
Wastewater Collection and Treatment
Wastewater generated within the project vicinity is collected and treated by the CVWD at the Mid -Valley
Water Reclamation Plant. An existing IS -inch force main was located in Jefferson Street and a portion of
Avenue 54. A wastewater collection system was proposed to be constructed within the original CCDSP
project site with one or two connection points to the existing force main. The EIR indicated that sewer lift
stations and force mains would be required at the collection points within the project site.
The proposed project was expected to generate approximately 212,575 gallons of wastewater per day. At
the time the EIR was prepared, CVWD staff indicated that the existing wastewater mains and treatment
plant had adequate capacity to serve the proposed project without causing any significant impacts on
their service levels. Impacts were determined to be less than significant, and no mitigation measures
were recommended or required.

Environmental Analysis
Solid Waste Disposal
The solid waste collection services for the City of La Quinta are operated and administered by Waste
Management of the Desert, a private hauler, under contract to the City. Waste Management of the Desert
is responsible for the collection and disposal of non -hazardous, mixed municipal waste. At the time the
EIR was prepared, the solid waste generated and collected within the City of La Quinta that was not
recycled, reused or otherwise diverted from landfill disposal was taken to the Edom Hill Sanitary Landfill
located northwest of Cathedral City. The Edom Hill Sanitary Landfill is operated by the Riverside
County Waste Management District.
The proposed project was projected to generate approximately 45,000 tons of construction wastes over its
build -out period. Using common recycling practices in effect at the time the EIR was prepared, this
amount could be reduced by at least 50 percent to 22,500 tons. To facilitate construction recycling efforts,
the City of La Quinta encourages developers to recycle the maximum amount of construction waste
possible.
The proposed project was projected to generate approximately 9,762 pounds per day (1,781 tons per year)
of solid waste. However, these numbers did not reflect any recycling activities on the part of the
generator. It was expected that participation in the City's residential solid waste recycling program, and
the recycling of green waste generated by landscaping and the golf course could exceed 50 percent, which
would comply with the goals specified in AB 939. Pursuant to the California Integrated Waste
Management Board's (CIWMB) "Model Ordinance" and the City's Zoning regulations, the proposed
projects individual project final site plans) are also required to provide adequate areas for collecting and
loading recyclable materials in concert with City of La Quinta efforts and programs to reduce the volume
of solid waste entering landfills.
At the time the EIR was prepared, the Riverside Countywide Integrated Management Plan indicated that
the existing landfills within the County could accommodate the volume of waste that is forecast to be
generated through the year 2008. After that, additional capacity would be needed to accommodate
existing as well as the future residents and businesses.
The impact of additional solid waste from development of the CCDSP project was identified as
potentially significant and measures were identified to mitigate this impact. However, because not all
solid wastes can be recycled, and because landfill space is a finite resource, the CCDSP project by itself
and in conjunction with cumulative development was considered to have an unavoidable and adverse

impact, even with mitigation. The City adopted a Statement of Overriding Considerations for this
unavoidable significant impact.
Analysis of Proposed Specific Plan Amendment
Water Supply and Distribution
Potable water would be provided to the Specific Plan Amendment project by the CVWD through a
system of wells, reservoirs, and water transmission lines. During the construction phases of
development, non -potable water would be obtained from the Coachella Canal and on -site wells. In
conjunction with the development of The Hideaway, 18-inch water mains were installed in Avenue 52
and Avenue 54. A pressure zone booster station is currently under design as part of The Hideaway
project and will bridge the water delivery between the CVWD's 145 and 235 pressure zones.
Additionally, water lines may need to be installed within the Specific Plan Amendment project's
frontages along Avenue 52, Avenue 54 and Monroe Street. Actual water system improvements will be
based upon the conditions of the Specific Plan Amendment project's existing recorded Domestic Water
and Sanitation Agreements with the CVWD and anv subsequent amendments. Per CVWD standards, a
well site would be required for every 70 acres of developed property. The conditioned 14 well sites for
the expanded Specific Plan Area will be provided by a combination of on -site and off -site locations
consistent with the CVWD Domestic Water Agreement and exhibits.
Irrigation lines currently exist in the CCDSP Area east of Madison Street site and will be relocated. An
existing CVWD irrigation main located along Avenue 52 and Avenue 53 will serve as a potential point of
connection. Several local service laterals will be abandoned. The CVWD has indicated that it would be in
the Specific Plan Amendment project's best interest to utilize these lines, if possible, (i.e., golf course and
landscaping irrigation) as fixture connections may not be possible, as the canal becomes an item of
historical interest. On -site groundwater wells will be established to provide a redundant and
supplemental source of irrigation water.
As a result of the reduced residential density proposed by the Specific Plan Amendment, potable water
consumption would be reduced. Based on the information above, the proposed Specific Plan
Amendment would not result in any new or substantially more severe impacts with regard to water
supply and distribution than those identified in the Certified CCDSP Final EIR.

Enroironmental Analysis
Wastewater Collection and Treatment
A 27-inch gravity sewer main was installed in Madison Avenue in conjunction with development of The
Hideaway. The Specific Plan Amendment project will be serviced via gravity connections to the existing
sewer line in Madison Avenue and a proposed gravity line in Monroe Street. The eastern portion of the
Specific Plan Amendment project site will initially be serviced by a sewer lift station. Once the proposed
CVWD sewer trunk main is installed in Monroe Street, the eastern portion of the Specific Plan
Amendment project site will be connected to the gravity trunk main. Actual wastewater system
improvements will be based upon the conditions of the Specific Plan Amendment project's existing
recorded Domestic Water and Sanitation Agreements with the CVWD and any subsequent amendments.
As a result of the reduced residential density proposed by the Specific Plan Amendment, wastewater
generation would be reduced. Based on the information above, the proposed Specific Plan Amendment
would not result in any new or substantially more severe impacts with regard to wastewater collection
and treatment than those identified in the Certified CCDSP Final EIR.
Solid Waste Disposal
After passage of the California Integrated Waste Management Act in 1989, La Quinta became extremely
proactive in the recycling and reduction of solid waste. La Quinta met the Act's requirement of diverting
fifty percent of solid waste from landfills by the year 1997, eight years early. As of 2002, La Quinta had a
diversion rate of fifty-eight percent. The City of La Quinta offers a number of waste reduction, recycling
and community clean up programs, including green waste collection, curbside recycling and household
hazardous waste collection.
Solid waste collected in the City is tipped at either the Edom Hill Transfer Station or the Coachella Valley
Transfer Station. The waste is then transferred to either the Lamb Canyon Landfill located between the
City of Beaumont and the City of San Jacinto or the Badlands Landfill in Moreno Valley, with a small
portion of waste transferred to the El Sobrante Landfill located east of Interstate 15 south of the City of
Corona for disposal. All of these facilities are owned and operated by the County of Riverside, except for
the El Sobrante Landfill, which is owned and operated by USA Waste Services.
Per the Integrated Waste Management Act of 1989, the City's and County's Source Reduction and
Recycling Elements are required to project disposal capacity needs for a 15-year period. Riverside
County has identified capacity to handle the existing development and the growth projected for the next

Environmental Analysis
15 years, including development and growth in La Quinta Solid waste impacts are considered less than
significant with mitigation 5
As a result of the reduced residential density proposed by the Specific Plan Amendment, solid waste
generation would be reduced. The mitigation measures adopted for the Certified CCDSP Final FIR
would be applicable to the Specific Plan Amendment and would mitigate the potential significant
impacts associated with the Specific Plan Amendment to a less than significant level. Therefore, the
proposed Specific Plan Amendment would not result in any new or substantially more severe solid waste
disposal impacts than those identified in the Certified CCDSP Final FIR related to solid waste collection
and disposal. Because the City is in compliance with state waste diversion requirements, and because the
City has identified long-term landfill capacity, solid waste impacts are less than significant, with
mitigation.
Mitigation Measures
Water Supply and Distribution
The following mitigation measures, identified in the Certified CCDSP Final EIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.
4.10-1. To ensure that future land uses do not include activities which unnecessarily waste water or
which consume exceptional amounts of water, the City will direct the project developers to
consult with the CVWD to develop appropriate water conservation measures for both
landscaping/irrigation requirements and plumbing controls. Consistent with CVWD's existing
and future water conservation plans, policies and standards, the City will require that the
developers implement the water conservation measures that are devised from the consultations
with CVWD, and will require compliance with the City's water conservation programs and
ordinance, to the extent applicable.
Wastewater Collection and Treatment
No mitigation measures were recommended or required in the Certified CCDSP Final FIR, and none are
recommended in this Addendum.

The following mitigation measures, identified in the Certified CCDSP Final EIR and adopted for the
CCDSP project, are applicable to the proposed Specific Plan Amendment project.
4.10-2. During project construction, the project developers shall separate recyclable construction waste
materials in separate bins, and shall arrange for transport of recyclable materials to facilities
which accept the materials. A list of recyclable construction materials and recycling facilities is
available, and shall be obtained, from the City of La Quinta. All recyclable materials shall be
recycled.
4.10-3. Builders competing for construction contracts shall be required to include proposals for the use of
building products made of recycled materials.
4.10-4. Green waste generated on the project site shall be treated in such a way as to avoid disposal in
landfills. This may be accomplished, for example, by composting either on site or at approved
facilities and mulching for use on and off site.
4.10-5. Prior to the issuance of building permits for each phase of the project, the project developers shall
prepare a solid waste management program for that portion of the site or for larger areas if more
efficient, for review and approval by the City of La Quinta. These programs shall maximize the
recycling potential of packaging materials (cardboard), mixed papers, and scrap ferrous
materials, and shall include designated areas for trash separation bins which are accessible to
waste haulers, and identification of materials that are to be recycled. The following provisions
shall be considered in the preparation of the plans:
• Locate recycling/separation areas in close proximity to dumpsters for non-recyclables,
elevators, loading docks, and primary internal and external access points. (From CIWMB
Model Ordinance)
• Locations of recycling/separation areas shall not conflict with any applicable federal, state or
local laws relating to fire, building, access, transportation, circulation, or safety.
• Locate recycling/separation areas so they are convenient for those persons who deposit,
collect, and load the recyclable materials. (From CIWMB Model Ordinance)
• Place recycling containers/bins so that they do not block access to each other.
• Solid waste collection/recycling areas are to be compatible with nearby structures, secure,
protected against adverse environmental conditions, clearly marked, adequate in capacity,
number and distribution, and contain a sufficient number of bins, to serve the recvcling
needs of the development. (From CIWMB Model Ordinance)

AESTHETICS
Summary of Analysis in the Certified CCDSP Final EIR
The Draft Specific Plan proposes a list of development regulations that would regulate the design and
development within the project site. Height limitations are proposed for the residential and golf course
structures so that heights would not block the existing views of the Coral Reef and Santa Rosa Mountains
from areas around the project site. The project is also designed so that residents of the project site and
guests to the clubhouse would have views of these mountains. The 1992 General Plan identified primary,
secondary and agrarian image corridors and gateway treatments in the City, each with specified design
guidelines. The proposed streetscape and entry features were determined to be considered aesthetically
pleasing and were determined to be consistent with, and compatible with, the similar streetscape and
entries that have been provided just south of the site along the perimeter of PGA West. For this reason,
the proposed project was determined not to degrade the existing visual character or quality of the project
site or its surroundings. Therefore, no mitigation measures were required or recommended.
The development of the proposed project was determined to increase the extent of nighttime light and
glare on the project site and surrounding vicinity, but would be subject to the City's "Dark Sky"
Ordinance which requires that light standards within parking lots, and exterior lights on buildings be
directed downward without the light source visible and appropriate shielded to prevent light spillage
and glare to adjacent properties. No mitigation measures were recommended or required.
Analysis of Proposed Specific Plan Amendment
Aesthetics impacts would be similar to those identified for the originally proposed project. Uses
developed within the proposed Specific Plan Amendment Area would be subject to and consistent with
_ the development regulations and design guidelines of the adopted CCDSP. Based on this and the
reduction in the residential intensity that would be allowed by the proposed Specific Plan Amendment,
