EXECUTIVE SUMMARY
The acquisition of the SilverRock Resort project site was approved by the City’s then Redevelopment Agency in 2002 and was originally known as the Ranch. The current iteration of the project was approved in 2014 under, among other governing PUBLIC HEARING ITEM NO. 1
5 CLICK HERE to Return to Agenda
agreements, a recorded Development Agreement (DA) that governs the site and guides the development of hotels and residential units around the existing golf course. Golf course realignment, temporary clubhouse facilities, mass grading and various master site infrastructure improvements have been completed. After the project had been paused because of the COVID-19 pandemic, in 2021 construction began on the luxury hotel and amenities, luxury residential units connected to the hotel, and permanent golf clubhouse, among other proximate buildings, but construction has ceased due to, among other reasons, bankruptcy of the former developer.
Since the filing of bankruptcy in August 2024 by the former developer, the City has been actively involved with the proceedings in the Bankruptcy Court, which has included, among other matters, the formation of a subcommittee that includes city staff, legal counsel and two council members to meet with multiple investor and developer groups to find a replacement owner and developer of the SilverRock Resort. A Reinstated and Amended Development Agreement (ADA) for SilverRock Resort is proposed to reinitiate development of the project site with a new developer, TBE RE Acquisition Co II LLC., a subsidiary of the applicant, Turnbridge Equities, enclosed as Exhibit A to the proposed ordinance.
In conjunction with the ADA, an Economic Development Subsidy Report, Transient Occupancy Tax (TOT) Sharing Agreement, Option to Purchase Real Property Agreement (Option Agreement) with attached Repurchase Option Agreement (Repurchase Option Agreement) are provided to complete the financial documentation for the project.
The project, and the related approvals, all would be conditionally approved and contingent upon an order issued by the U.S. Bankruptcy Court for the District Delaware (Bankruptcy Court) authorizing the sale of the Phase 1 Property to Turnbridge Equities’ designated subsidiary.
FISCAL IMPACT
The SilverRock Resort project will require substantial investment by the applicant, Turnbridge Equities. The City has agreed that incentives are required to assure the successful completion of development and long-term economic viability of the project. Among other state laws, California Government Code Sections 53083 and 52201 authorize cities to provide public subsidies to further economic development and opportunities as long as, among other requirements, the City completes an analysis of both the amounts to be credited to the developer, and the returns that can be expected as a result of the project, prior to providing the incentives that would benefit the developer. In this case, the City has identified three incentives:
6 CLICK HERE to Return to Agenda
1) A Transient Occupancy Tax revenue sharing agreement whereby an amount equal to 90% of TOT collected on a portion of the project site will be used as a basis for providing “rebate” payments to the developer for 10 years, and equal to 60% of TOT collected on a portion of the project site for the following 5 years, after which time all TOT revenue sharing with the developer will expire.
2) A fixed purchase price of $17 million for “Phase 2” property, including the existing golf course, the Ahmanson Ranch House and the portion of the “Phase 2 Property” subject to an option to purchase, if certain conditions, including the successful completion of the luxury hotel, golf clubhouse and associated amenities of the Phase 1 project, are met by the developer.
3) A potential subsidy that would benefit development of the Phase 1 project, based on an amendment to a Debtor-In-Possession (DIP) financing arrangement (DIP Financing Agreement) between the City and debtors, in an amount up to $13 million, which provides the debtors with liquidity to sell the Phase 1 property, wind down their estate, and prosecute a plan of liquidation through the Bankruptcy Court. The City conservatively estimates that $5.5 million of the up to $13 million will be repaid, resulting in a net incentive of $7.5 million.
The City’s independent consultant has completed that analysis (Exhibit A of the attached Economic Development Subsidy Report Resolution), which shows that the City’s TOT sharing incentive will provide $106.6 million over 15 years, and that the City will receive net revenues over 30 years of $301.9 million ($263.6 million net of the amended DIP credit and Phase 2 property incentive). This includes TOT, sales tax and property tax generated by the project.
In addition, the project will generate 2,500 to 3,000 jobs during construction, and once open 445 full time equivalent permanent jobs, the indirect economic benefits of new guests’ and residents’ discretionary spending in the City, and the potential for increased investment in the City as a result of the project. This report satisfies the requirements of law under Government Code Sections 53083 and 52201.
BACKGROUND/ANALYSIS
Development Agreement
A detailed background and summary of the SilverRock Resort Area is included in the Recitals to the ADA (Exhibit A of the Ordinance), and incorporated into this report by reference.
Originally, the former La Quinta Redevelopment Agency purchased the approximate 525- acres project site, with the intention that its use and development would be a world-class destination golf resort/luxury residential and public amenities project, to act as a substantial revenue generator for the City. In 2012, after the construction of the Arnold Palmer Classic Golf Course was completed, the State dissolved redevelopment. The City, with the approval of the State, invested in the entire SilverRock Resort Area so as to maintain control and ultimately oversee its sale and development for those original purposes.
In 2014, SilverRock Development Company, Inc., the former developer, applied to the City for approval of DA 2014-1001, among other agreements, that were within the purview of the Council. DA 2014-1001 incorporated one of those other agreements, the Purchase, Sale, 7 CLICK HERE to Return to Agenda
and Development Agreement, as amended (collectively, PSDA), which governed the former project.
Generally, the former project consisted of approximately 132+/- acres conveyed to the former developer for the construction of a luxury hotel, a lifestyle hotel, spa, conference center and branded residential components, a permanent golf clubhouse, and a mix of commercial and residential areas to complement the existing golf course and a potential future golf course.
Since 2014 and per the PSDA, there have been parcel adjustments through lot-line adjustments, and there were various development permits issued for infrastructure, the luxury hotel and facilities, and the luxury residential component.
Development of the SilverRock Resort project was delayed due to, among other reasons, the bankruptcy of the former developer. The City, working with the former developer (referred to in the bankruptcy proceeding as the debtors) and its current controlling manager (a former Bankruptcy Court judge with expertise in bankruptcy work-outs), has been intricately involved with the proceedings in Bankruptcy Court to facilitate a sale of the properties owned and partially developed by the former developer to a new owner and developer.
As part of the bankruptcy proceedings, the City and debtors negotiated, and the Bankruptcy Court approved, a set of “Bid Procedures” that, among other provisions, authorized the marketing opportunity for the purchase of the debtors-owned property referred to as “Phase 1” and “Phase 1 Property”. The marketing opportunity also referenced City-owned property, referred to as “Phase 2” and “Phase 2 Property” that is comprised of approximately 195+/- acres. While the Phase 2 Property is subject to the SilverRock Resort Area Specific Plan, it is not owned by the former developer/debtors, but the former project included the possibility of an option “springing” into effect for the possible acquisition of the Phase 2 Property upon completion of specified project components in Phase 1.
Under the Bankruptcy Court-approved Bid Procedures and other relevant orders, as part of the purchase of Phase 1, the developer is required to enter into an ADA for development of the Phase 1 Property, along with several other documents that will implement the project.
Attachment 2 shows the vicinity map for the project area with the phases labeled.
The ADA is attached as Exhibit A of the Ordinance. The ADA describes the developer’s obligations for development, including the following major components (see Attachment 3 for proposed land plan):
Phase 1 Development Components:
Development of a 150± room luxury hotel in the area of the partially constructed Montage Hotel. The hotel must include a spa, restaurant, conference and banquet facilities, pool/recreation facilities, and “back of house” facilities. Development of a public golf clubhouse, relocated from its current location to an adjacent area of the luxury hotel and SilverRock/Talus Way. Residential lots branded to the hotel, in the area where the single-family units were partially developed, and allowing short-term vacation rentals (STVR) through the hotel’s centralized management.
A private clubhouse and pool/recreation area for residential units to be located where the former project’s public golf clubhouse would be. 8 CLICK HERE to Return to Agenda
Additional for sale residential units on the east half of the Phase 1 property, which may include STVRs.
Landscaping and trails within Phase 1 and along its perimeter adjacent to Avenue 52.
Construction of all infrastructure (roads, utilities, etc.) necessary to serve Phase 1.
Potential purchase of the land within Phase 2, the City-owned property in the east and south portion of the site.
The implementation of these development components will be undertaken separately, with future Site Development Permits, Tract Maps, or other means as needed to implement them, except to the extent that there are expedited permitting provisions proposed in the ADA to allow for the continued securing and clean-up, improvement, and removal of partially completed improvements to effectuate the Phase 1 Development Components. Pursuant to the proposed project, the developer will use components of the existing partially completed structures, while other parts, namely the partially constructed luxury residential homes and partially built spa, will be demolished to effectuate development.
The ADA also contains a number of provisions relating, but not limited to, the developer’s and the City’s responsibilities, financing of project components, implementation of CEQA mitigation measures, and minimization of impacts to golf play and operation.
There is a schedule of performance that includes “hard dates” for the commencement and completion of construction for the luxury hotel and amenities, and for the public golf clubhouse. For the luxury single family home sites, the ADA and schedule of performance require the delivery of finished lots that are utility ready and available for purchase as custom homesites that, when lots are purchased, must be constructed timely and in accordance with requirements of the luxury hotel operator. Dates for the luxury homesites are approximate for commencement and completion, but the ADA remains binding on these project components until 50% of the finished, utility-ready lots have homes constructed on them. The luxury condominiums component has similar allowances for market conditions to govern phasing of that project components’ development.
Once the luxury hotel and amenities are constructed and opened for marketing to regular guests, the ADA allows for the transfer of the golf course and Ahmanson Ranch House from the City to the developer, with land use covenants attached to both that, in general, require the continued availability of the golf course as part of the luxury hotel operations. Additionally, the ADA and land use covenants obligate the developer to maintain and operate the golf course with continued access to La Quinta residents at a reduced rate.
Also after the luxury hotel and amenities are constructed and opened for marketing to regular guests, the developer will have a right to purchase the Phase 2 Property – excluding the portion of this property that contains SilverRock Park and adjacent retention basin – pursuant to an Option Agreement. The developer cannot own the Phase 2 Property until specified conditions are met in the ADA and Option Agreement, which includes the requirement that the relocated public golf clubhouse has been constructed and open for use in connection with the golf course. However, the ADA does allow, at the election of the developer, for development of the Phase 1B single-family residential project to be integrated with “non9 CLICK HERE to Return to Agenda
vertical” development of the Phase 2 property, such as grading and infrastructure installation.
A separate license agreement with the City would be required, with insurance and indemnity protections (among other requirements), and the developer must provide sufficient evidence to the City for the financing and completion of any “non-vertical” development on Phase 2 prior to owning that property pursuant to the Option Agreement.
Additional Documents and Agreements
In addition to the ADA, other documents and agreements are provided to the Cit Council for review and approval, as follows:
1) Economic Subsidy Report pursuant to Government Code Sections 53083 and 52201; 2) TOT Revenue Sharing Agreement; and
3) Option to Purchase Real Property Agreement, which includes a City Repurchase Option Agreement.
California law authorizes cities to provide incentives that further economic development and opportunity. Government Code Section 53083 defines “economic development subsidies” broadly to include, and is not limited to, grants, loans, loan guarantees, land price subsidies, matching funds, tax abatements, tax exemptions, and tax credits. Whenever a subsidy is more than $100,000, a report is required that includes specified information, such as projected tax revenue resulting from a project and jobs created as a result of a project. Similarly, Government Code Section 52201 authorizes the sale or leasing of City-owned property for a value that takes into consideration covenants, conditions, and constraints to development unique to a site, in order to create an economic opportunity. A report likewise is required that includes, among other specified information, an explanation as to why the sale of the publicly owned property will assist in the creation of an economic opportunity.
The Economic Development Subsidy Report, summarized under “Fiscal Impacts,” above, provides a summary on the incentives being provided to the developer, the economic benefits to the City, and includes the information required under Government Code Sections 53083 and 52201. The Economic Development Report must be adopted by a resolution, and the incentives analyzed in that report would be implemented through two agreements described below (the TOT Revenue Sharing Agreement and Option Agreement), and a third pending item before the Bankruptcy Court involving a proposed amendment to the DIP Financing Agreement.
The TOT Revenue Sharing Agreement sets forth the terms and conditions under which TOT revenue will be used as a basis for determining a tax “rebate” amount that will then be paid by the City to the developer from available revenues for providing public subsidies. The TOT actually collected by the City from the “Phase 1A” area, as shown on the Vicinity Map, is the area of the project that would be used to calculate the amount of the tax rebate. This incentive would be provided to the developer for a period of 15 years following the completion of the hotel being open for marketing to guests. The agreement also provides rights to the City, including termination of the agreement and a day-for-day reduction in the TOT rebate payment to the developer, for failing to meet their obligations for completion and operation of the luxury hotel.
10 CLICK HERE to Return to Agenda
The Option Agreement sets forth the terms and conditions under which the developer may purchase from the City the Phase 2 Option Property, which is noted in the Vicinity Map and generally includes all of the real property, including the existing golf driving range, in the northeastern portion of the SilverRock Resort Area, except the existing SilverRock Park and adjacent retention basin, which the City will continue to own. Among other key conditions to being able to close an escrow for the purchase of the Phase 2 Option Property, the development of the hotel must be completed prior to the exercise of the Option and the public golf clubhouse must be completed prior to closing the escrow for developer’s purchase of this property. Additionally, prior to closing the escrow, the City and developer must have negotiated and entered into either an amendment to the ADA currently before the Council or a new statutory development agreement that will govern with more precision the phasing of development and other mutually agreed upon terms for the Phase 2 Option Property after the developer acquires it. The Economic Development Subsidy Report summarizes the purchase price and the significant constraints to development that support the subsidies due to substantial costs associated with any development at the site, such as legally imposed onand off-site improvements that include, among other utility costs, electric utility substation upgrades.
If escrow closes and the developer acquires the Phase 2 Option Property, there is a Repurchase Option Agreement that sets forth terms and conditions for the City to have the right to repurchase the Phase 2 Option Property if the developer falls into a material default regarding the development of the Phase 2 Option Property according to the required amended ADA or new development agreement (noted above).
Should the Council wish to enter into the ADA, these additional documents complete the implementation of the ADA and project as proposed by Turnbridge Equities, and are therefore a part of the ADA’s approval. A single Resolution is provided for the approval of these additional documents and agreements. The incentive relating to the amendment to the DIP Financing Agreement is controlled by the debtors and, as of the date of this public hearing, is pending in the Bankruptcy Court.
Bankruptcy Court Proceedings
On August 5, 2024, SilverRock Development Company (and affiliates) filed petitions for bankruptcy protection in the Bankruptcy Court. Per prior Council authorization, the City retained Special Counsel and has continuously been working with the debtors as the case moves forward. Pursuant to “Bid Procedures” that included an auction for the sale of the debtors’ estate, which is the “Phase 1 Property” that is part of the applicant’s project, the debtors must present to the Bankruptcy Court the “successful bidder,” selected purchaser and future developer of this property.
After a substantial marketing and interviewing phase, and after pre-auction negotiations between debtors, the City and potential bidders, and after the completion of the auction in August, the debtors received input from the City as to the most qualified bidder, as required by the Bid Procedures. The debtors have filed a Motion Approving the Sale of the Debtors Assets (Sale Motion), identifying the subsidiary of Turnbridge Equities as the “successful bidder” and recommended buyer and future developer of the Phase 1 Property. Because the Bankruptcy Court must approve the sale of the debtor’s assets before Turnbridge Equities 11 CLICK HERE to Return to Agenda
can own the Phase 1 Property, any Council action that would approve the ADA and related items must be conditioned on the Bankruptcy Court authorizing the sale of the debtors’ estate.
Along with the Sale Motion, a related Motion to Amend the DIP Financing Agreement is pending. That motion and its various attachments, filed in the Bankruptcy Court, are referenced as being part of this report because they have the terms and conditions that would implement the DIP Financing Agreement incentive, which is summarized above and in the Economic Development Subsidy Report.
Public Hearing Notices
The public hearing notice for the project was advertised in The Desert Sun newspaper on September 11, 2025, and distributed to properties within 500 feet of the site. At the time of publication of the agenda, staff had not received any written comments.
The public hearing notice for the Economic Development Subsidy Report was advertised in The Desert Sun newspaper on September 8, 11, and 18, 2025. At the time of publication of the agenda, staff had not received any written comments.
Planning Commission Review
The Planning Commission reviewed the ADA at its meeting of September 9, 2025. After considerable discussion, with one planning commissioner unable to participate and vote due to a financial conflict of interest based on the location of a real property interest within 500 feet of the project’s boundary, the Planning Commission unanimously recommended (6-0- 1) that the Council approve the Addendum to Environmental Assessment 2002-453, and adopt an Ordinance approving the ADA. The additional documents and agreements are not under the Planning Commission’s review authority.
ENVIRONMENTAL REVIEW
A Development Agreement is a “project” as defined by the California Environmental Quality Act. As a result, the City considered the Project and determined that an Addendum to the Mitigated Negative Declaration (MND) for Environmental Assessment 2002-453 has been prepared and is provided as Exhibit A of the EA Resolution.
ALTERNATIVES
The Council may elect to deny the ADA and supporting agreements or continue the item and provide staff with direction as to changes that it wishes to see implemented in any of the documents described in this staff report.

Meridian Consultants 1.0-3 SilverRock Resort Project Addendum September 2025
1.0 INTRODUCTION
This Addendum has been prepared to analyze the potential environmental effects associated with the proposed approval of agreements to implement the approved SilverRock Resort Project (SRR Project or Project). The City of La Quinta (City) is proposing to approve a Reinstated and Amended Development Agreement, an Option Agreement for the Phase 2 Land, a Transient Occupancy Tax revenue sharing agreement, and ancillary agreements or amendments to recorded covenants. The first phase of development currently proposed includes a 154-room Luxury Resort Hotel with supporting facilities, 192 single-family and condominium resort residential units and a new clubhouse for the existing public golf course in Planning Areas 2-7. Subsequently, approval of Site Development Permits (SDPs), amendments to previously approved SDPs, subdivision maps and other implementing approvals, will be requested to develop the 2025 SilverRock Master Plan Project (2025 Project; Project), which would allow the development of resort, recreational, retail/commercial, and residential uses as permitted by the SilverRock Resort Specific Plan as approved by the City for the SilverRock Resort site.
1.1 PRIOR ENVIRONMENTAL REVIEW
The SilverRock Resort Project has been reviewed by the City of La Quinta in a series of environmental review documents prepared since 2002, including a 2002 Mitigated Negative Declaration (MND), and Addenda to the Adopted MND in 2006 and 2014 (Previous Assessments). Background information on these Previous Assessments and approvals is presented below.
1.1.1 2002 Mitigated Negative Declaration (2002 MND)
In 2002, an Environmental Assessment (EA 2002-453) was prepared supporting the adoption of a Mitigated Negative Declaration (2002 MND) evaluating the acquisition of the 707-acre SilverRock Resort site by the City of La Quinta Redevelopment Agency. The site was acquired to meet the City’s goals of providing public recreation and generating recurring revenue by facilitating resort-oriented development. The 2002 MND evaluated a master development plan that included two 18-hole public golf courses, a hotel with a conference center, a clubhouse, timeshare or condo-hotel units, and supporting commercial uses. Approximately 160 acres of the western portion of the site within the Santa Rosa Mountains were identified for permanent preservation as open space. Following the adoption of the 2002 MND, the City constructed and opened the Arnold Palmer Classic Golf Course in 2005 on approximately 173 acres of the site.
1.1.2 2006 Addendum
In 2006, the City of La Quinta approved the SilverRock Resort Specific Plan to guide the phased development of approximately 546 acres of the SilverRock site with resort uses. An Addendum to the 2002 MND (2006 Addendum) was prepared to evaluate the proposed Specific Plan. 19 CLICK HERE to Return to Agenda
1.0—Introduction
Meridian Consultants 1.0-4 SilverRock Resort Project Addendum September 2025
The Specific Plan was prepared by the City to ensure quality development consistent with the goals, objectives, and policies of the City’s General Plan. The Specific Plan defines the location, type, and amount of development allowed within the Specific Plan Area, while providing a degree of flexibility to allow future development to respond to the opportunities in the marketplace for a unique resort development.
The Specific Plan established a land use framework by establishing eight Planning Areas (PAs) to guide the development of a master-planned resort community with two public golf courses, multiple hotels (including boutique and conference hotels), residential units, a mixed-use retail village, and supporting amenities as identified in Table 2-2. The plan included design and development standards aligned with the City’s General Plan and excluded the previously preserved 160-acre portion of the Santa Rosa Mountains.
The approved Specific Plan allows minor modifications without a Specific Plan amendment as follows:
• The addition of new information to the Specific Plan maps or text that do not change the effect of any regulation. The new information may include more detailed, site-specific information. If this information demonstrates that Planning Area boundaries are inaccurately designated, based upon the goals of the Specific Plan, said boundaries may be adjusted or redesignated to reflect a more accurate depiction of on-site conditions without requiring a Specific Plan Amendment.
Adjustments to the golf corridors may be made, resulting in a corresponding change to the adjacent development parcel, without the requirement of a Specific Plan Amendment. • Changes to the community infrastructure, such as drainage systems, roads, water, and sewer systems, etc., which do not have the effect of increasing or decreasing capacity in the project area beyond the specified density range nor increase the backbone infrastructure construction or maintenance costs.1
The 2006 Addendum concluded that the proposed Specific Plan would not result in any new or substantially more significant impacts than were identified in the Adopted 2002 MND.
1.1.3 2014 Addendum
In 2014, the City of La Quinta prepared a second Addendum to the 2002 Mitigated Negative Declaration (2014 Addendum) to evaluate a refined master plan for the SilverRock Resort project in response to evolving market conditions and support the approval of a series of agreements to implement the project, including a Development Agreement (DA) and a Purchase, Sale, and Development Agreement (PSDA) pursuant to California Government Code Section 65864 with a master developer for development of resort, recreational, retail/ commercial, and residential uses as permitted by the Specific Plan.

1.0—Introduction
Meridian Consultants 1.0-5 SilverRock Resort Project Addendum September 2025
The 2014 Master Plan as evaluated in the Addendum included a hotel, spa, banquet room, residential units, commercial/retail space, a golf clubhouse, and an additional 18-hole golf course As summarized in Table 2-2. The 2014 Addendum concluded that the proposed Specific Plan would not result in any new or substantially more significant impacts than were identified in the Adopted 2002 MND.
1.2 PREVIOUS APPROVALS
In 2006, the City of La Quinta approved the SilverRock Resort Specific Plan to guide the phased development of the approximate 546 acre the SilverRock site. An Addendum to the 2002 MND (2006 Addendum) was prepared to evaluate the proposed Specific Plan. The 2014 DA, PDSA and amendments to the PSDA allowed development in Planning Areas 2 to 9 as defined in the approved Specific Plan. The PSDA and subsequent amendments addressed financing, construction timelines, performance schedules, and financial incentives for the phased construction of luxury hotels, branded residences, golf villas, a new golf clubhouse, a conference center, and related infrastructure. PSDA Amendment No. 3, November 2018, amended and restated key terms of the original PSDA between the City and the Developer and included an updated master plan (2018 Master Plan) shown Figure 1-1: 2018 SilverRock Resort Master Plan.
A series of Site Development Permits (SDPs) approved site, architectural, and landscaping plans for Planning Areas 2-7 as delineated in the 2025 Project in accordance with the SilverRock Specific Plan and applicable zoning and environmental regulations. The SDPs established project conditions, design requirements, environmental compliance measures, and public infrastructure obligations.
1.3 PROPOSED 2025 SILVERROCK RESORT MASTER
PLAN
The 2025 SilverRock Resort Master Plan, as shown below in Figure 2-4: 2025 SilverRock Master Plan, includes hotel and resort residential uses as permitted by the SilverRock Specific Plan along with the second 18-hole golf course and related support and amenity facilities. Development of one hotel is now proposed with resort residential units. Overall, the 2025 SilverRock Master Plan reflects a reduced intensity of hotel and residential development compared to the 2018 Master Plan as shown in Table 2-2: Comparative Land Use Summary: Prior Environmental Reviews and the 2025 SilverRock Master Plan.

1.0—Introduction
Meridian Consultants 1.0-6 SilverRock Resort Project Addendum September 2025
1.4 PURPOSE OF AN ADDENDUM
The California Environmental Quality Act (CEQA) and State CEQA Guidelines define standards and the procedure for determining the level of additional environmental review required when an Environmental Impact Report (EIR) has been certified or a Negative Declaration adopted for a project.2
An Addendum to an adopted MND is appropriate where the lead agency has determined that changes to the project, changed circumstances, or new information would not result in the identification of new significant impacts or a substantial increase in the severity of impacts identified in the adopted MND. An Addendum is appropriate where a lead agency has determined that none of the conditions described in CEQA Guidelines Section 15162 call for the preparation of a subsequent EIR or negative declaration have occurred.
Public review of an Addendum is not required by CEQA. Instead, the information in an Addendum is to be considered with the adopted MND prior to a decision being made on actions proposed.
This Addendum provides:
1. An update to the information in the adoptedMND on the existing environmental conditions under which the SRR Project will be undertaken.
2. An analysis of the potential environmental effects of the 2025 Project as compared to the environmental effects of the SRR Project as analyzed in the 2002 MND and prior Addenda.
An Addendum is the appropriate document to update the information in the adopted MND for the following reasons:
1. No substantial changes are proposed to the SRR Project that will require major revisions of the adopted MND because there are no new significant effects or any substantial increase in the severity of previously identified significant impacts.
2. No substantial changes in circumstances under which the SRR Project will be undertaken have been identified that will require major revisions of the adopted MND as there are no new significant environmental effects or any substantial increase in the severity of previously identified effects.
3. No new information of substantial importance has been discovered that was not known and could not have been known with the exercise of reasonable diligence at the time the adopted MND was prepared. Specifically, a review of the current existing conditions and the 2025 Project demonstrates the following:
2 CEQA Guidelines, Sections 15162–15164.

Table 2-4: 2025 SilverRock Master Plan Summary provides an overview of the development included in the 2025 Project. PAs 1, 11 and 12 are City owned land, and as shown in Table 2-3, are proposed for recreational use. PAs 9 and 10 in the 2018 Master Plan included resort residential units and commercial space. The intensity of residential units and commercial space is reduced in the 2025 Project and PAs 9 and 10 were combined into PA 8 in the 2025 Project, as shown in Table 2-2.
The 2025 Project includes a revised development program for the first phase of the Project. This first phase includes the development of a 154-room Luxury Resort Hotel with supporting facilities, 192 single-family and condominium resort residential units and a new clubhouse for the existing public golf course in PAs 2-7. The 2025 Project reduces the intensity of development in these planning areas compared to the 2018 Master Plan.
The second phase includes the future development of an 18-hole private golf course, 253 resort residential units and 40,000 square feet of commercial development in PA 8. This second phase of 31 CLICK HERE to Return to Agenda

2.0—Project Description
Meridian Consultants 2.0-10 Addendum to the SilverRock Resort Project September 2025
Further description of the development proposed in each Planning Area is provided below.
Planning Area 1
Planning Area 1 includes the existing 173-acre Arnold Palmer Classic Golf Course and golf course maintenance facility site. The Project proposes to upgrade the existing golf course and realign a portion of SilverRock Way adjacent to the proposed public golf clubhouse in Planning Area 4 (PA 4).
The southern segment of SilverRock Way would be removed to allow clubhouse guests to access the golf course directly without crossing a vehicular roadway. To maintain circulation, the Project would extend Ahmanson Way between PA 4 and PA 5 to connect with the northern segment of SilverRock Way.
Planning Area 2
In Planning Area 2 the re-use or demolition of the partially constructed homes is proposed to allow the development of 29 luxury branded resort residences, each with four to five bedrooms and ranging from approximately 4,000 to 6,000 square feet in size. These residences will be privately owned but maintain a direct affiliation with the adjacent luxury hotel. The hotel owner and future residential owner(s) will have the option to make their units available for short-term vacation rental through a hotel-managed rental program. The purchase and sale agreement and property covenants would require that all rentals must be managed through the hotel reservation system, subject to applicable laws.
Planning Area 3
In Planning Area 3, the re-use or demolition of the partially constructed hotel buildings is proposed to allow the development of a 154-unit luxury hotel, with approximately 250,000 SF of total space.
The existing Ahmanson House property is intended to be renovated for use as a restaurant or other hotel amenity, consistent with the existing project approvals. The luxury hotel would use the new Back of House and Banquet facilities in Planning Area 5.
Planning Area 4
In Planning Area 4, development of a new approximately 17,000 SF golf clubhouse is proposed to serve the golf course(s) on the Project Site. It will replace the partially constructed golf clubhouse currently occurring in Planning Area 8 (see below).
Planning Area 5
In Planning Area 5, the partially constructed one-story 81,000 SF conference/shared services buildings would be demolished to allow for the development of a 25,000 SF banquet facility and a 30,000 SF back of house (BOH) facility.
34 CLICK HERE to Return to Agenda
2.0—Project Description
Meridian Consultants 2.0-11 SilverRock Resort Project Addendum September 2025
Planning Area 6
In Planning Area 6 the demolition of the partially constructed public golf clubhouse is proposed to allow for the development of 70 luxury branded resort condominium units, each with two to five bedrooms, and ranging from approximately 2,000 to 4,000 SF in size. Development in this Planning Area would also include an approximately 20,000-SF clubhouse building that would provide amenities for residents along with other amenities like pools, tennis, pickleball, and padel, among others. These residences will be privately owned but maintain a direct affiliation with the adjacent luxury hotel. The hotel owner and future residential owners will have the option to make their units available for short-term vacation rental through a hotel-managed rental program. The purchase and sale agreement and property covenants would require that all rentals must be managed through the hotel reservation system, subject to applicable laws.
Planning Area 7
Planning Area 7 is proposed to allow for the development of 93 luxury branded resort residences.
These residences will be privately owned but maintain a direct affiliation with the adjacent luxury hotel. Future residential owners will have the option to make their units available for short-term vacation rental through a hotel-managed rental program. The purchase and sale agreement and property covenants would require that all rentals must be managed through the hotel reservation system, subject to applicable laws.
Planning Area 8
In Planning Area 8, a second 18-hole golf course is proposed with up to 253 private residences and 40,000 SF of commercial uses. This is the same program of development for this area included in the 2018 Master Plan. Planning Area 8 as defined in the 2025 Plan includes PAs 8, 9 and 10 as defined in the 2018 Plan.
Planning Areas 11 and 12
PAs 11 and 12, City owned land planned for recreational use, are not part of the proposed 2025 project. These PAs include SilverRock park, which has been developed, and the other recreational elements will be considered by the City as development occurs.
2.4 SCHEDULE
Construction of the 2025 Project would consist of two phases – Phase I and Phase II. Phase I would include the development of PAs 1 to 7 and Phase II would include the development of PA 8. Each phase would include site preparation (including clearing, grubbing, and grading), infrastructure construction (including internal street development, electric, natural gas, and telecommunications improvements), and construction of individual buildings. No building construction timeline is available because the Specific Plan Area would be built out depending on market conditions. 35 CLICK HERE to Return to Agenda
2.0—Project Description
Meridian Consultants 2.0-12 SilverRock Resort Project Addendum September 2025
Phase I is anticipated to occur over the course of seven years, with a start in November 2026 and completion by April 2033. A breakdown of each PA in Phase I detailed below. • Development of PAs 1, 3, 4 and 5 is anticipated to be from November 2026 to May 2029. • PA 2, which would develop approximately 29 single-family homes, is estimated to start in early 2027. Construction of each house is expected to have a duration of 20 months, but they will not all start at the same time. The last house is estimated to begin construction in late 2029 and finish mid-2031.
• PA-6, which would develop 70 luxury condo units, is estimated to start early 2027 and have a 24- month duration per building and with a total of 10 buildings. Assuming each building is one month behind the next, Building 1 is estimated to start in Jan 2027 and Building 10 is estimated to be complete by Oct 2029. Overall, condo building construction would start in January 2027 and be completed in October 2029.
• PA 7, which would develop 93 single-family homes, is anticipated to begin in 2030 and be built in phases over 38 months, into April 2033.
Phase II, which would include the development of PA 8, is anticipated to be over the course of 11 years following the completion of Phase I, from 2035-2045. 36 CLICK HERE to Return to Agenda
Meridian Consultants 3.0-1 Addendum to the SilverRock Resort Project September 2025
3.0 IMPACT ANALYSIS
This section includes separate subsections for each environmental topic addressed in the 2002 MND. Each topical section presents a summary of the information and conclusions of the analysis in the Previous Assessments. Updated information reflecting any changes in the circumstances under which the proposed Project will occur is presented for each topic, followed by analysis of the environmental impacts of fully developing the uses as proposed by the proposed Project and as compared to the Previous Assessments. The following environmental topics addressed in the previous environmental review documents are addressed in this Addendum:
• Land Use and Planning • Hazards
• Population and Housing • Noise
• Geology and Soils • Public Services
• Water • Utilities and Service Systems
• Air Quality • Aesthetics
• Transportation/Circulation • Cultural Resources
• Biological Resources • Recreation
• Energy and Mineral Resources • Greenhouse Gases
The adopted 2002 MND identified the environmental effects of the 2002 Project that would be less than significant, avoided, or substantially reduced to less than significant levels by the implementation of the adopted mitigation measures.
The 2006 and 2014 Addenda evaluated the environmental effects of the development analyzed in the addendum as compared to the development analyzed in the 2002 MND and determined the revisions as proposed would not result in any new or substantially more severe significant impacts than identified in the 2002 MND.

3.0—Impact Analysis
Meridian Consultants 3.0-2 Addendum to the SilverRock Resort Project September 2025
3.1 LAND USE AND PLANNING
3.1.1 Thresholds
a. Physically divide an established community?
b. Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect?
c. Conflict with any applicable habitat conservation plan or natural community conservation plan?
3.1.2 Summary of Findings in Previous Assessments
The Adopted MND and prior Addenda concluded that the development of the SilverRock Resort Project would not disrupt or divide the existing community because the Project Site consisted of vacant and partially developed land situated within a developed area. The Project Site is surrounded on the north, east and south by similar golf course communities including the Citrus Club at PGA West golf course and residential community north of Avenue 52; the Mountain View Country Club golf course and residential community north of Avenue 52 and east of Jefferson Street; the Hideaway golf club and residential community east of Jefferson Street; and the PGA West golf course and residential community south of the Project Site. The western 160 acres of the site adjacent to the Santa Rosa Mountains is preserved as open space. The prior project was planned to be compatible with these adjacent resort and residential communities.
Consistent with the General Plan designations for the Project Site of Open Space – Recreation (OSR), Tourist Commercial (TC), and Open Space – Natural (OS-N) the Project has long been envisioned as a golf resort with complementary residential, hotel, and commercial uses. The proposed resort, residential, and commercial land uses were found to be compatible with surrounding land use patterns, and buffers such as golf courses were planned along the periphery to ensure compatibility and transition with adjacent neighborhoods.
The uses permitted by the Specific Plan were determined to be consistent with the City’s General Plan land use designations and zoning. No inconsistencies with applicable plans or policies were identified. Subsequent refinement of the Project over time has reduced the overall intensity of the allowed uses, including fewer residential units, fewer hotel room keys, and less commercial space than previously analyzed. The Project remained consistent with the General Plan and Specific Plan.
In addition, the Prior Assessments concluded the Project would not conflict with the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) and identified mitigation measures (MM) BIO-2 (building bighorn sheep fencing) to ensure compliance with the CVMSHP by focusing on the protection and separation of bighorn sheep that live in the Santa Rosa Mountains west of the Project Site from urban development.
38 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-3 SilverRock Resort Project Addendum September 2025
The Project Site is not located directly within the CVMSHCP Conservation Areas, but the Project Site is located adjacent to the Santa Rosa and San Jacinto Mountains Conservation Area, and the project would be required to pay the CVMSHCP/Natural Community Conservation Plan Mitigation Fee as required by design feature 1 identified in the 2035 General Plan.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to land use and planning. All impacts remained less than significant, and no mitigation measures specific to land use and planning were identified in the Previous Assessments.
3.1.3 Existing Conditions
The City consists of residential, resort, and commercial development surrounded by hillside and mountain open space areas. Most of the land within the City has been developed with a few undeveloped infill lots located throughout the urbanized area.
As detailed in Section 2: Project Description, the 2014 DA, PDSA and subsequent amendments, and SDPs allowed development in PAs 2 to 9. Construction began on several buildings, including the conference center/shared services facility, golf clubhouse, hotel, spa, guest rooms, and branded hotel residences, but was not completed, leaving partially constructed and unoccupied structures on the Project Site. The Project Site currently includes the Arnold Palmer Classic Golf Course, the Ahmanson House, and these partially constructed buildings.
The General Plan land use and zoning designations for the Project Site remain unchanged since the 2014 Addendum. As depicted in Figure 3.1-1: General Plan Land Use Map, most of the Project Site has a General Plan land use designation of OS-R, with the central western portion designated as TC, and the Coachella Canal area designated as OS-N. As depicted in Figure 3.1-2: Zoning Map, corresponding zoning designations include Golf Course (GC) and Park and Recreation (PR) for OS-R, Tourist Commercial (CT) for TC, and Floodplain (FP) for OS-N.
The Tourist Commercial designation allows tourism-related land uses, including resort hotels, hotels and motels, and resort commercial development, such as conference centers, restaurants, resortsupporting retail and services. The Recreational Open Space designation applies to parks, recreation facilities, including driving ranges, club houses, and athletic facilities, as well as public and private golf courses. The Natural Open Space designation is applied to areas of natural open space, whether owned by private parties or public entities. Little development is permitted in this designation with the exception of trail or trailhead development.

Meridian Consultants 3.0-6 SilverRock Resort Project Addendum September 2025
General Plan land use designations surrounding the Project Site include OS-R and Medium and High Density Residential (MHDR) to the north; OS-R, MHDR and OS-N to the east; OS-R and Low Density Residential (LDR) to the south; and OS-R, LDR and OS-N to the west. Zoning designations surrounding the Project Site include GC and Low Density Residential (RL) to the north; GC, Medium High Density Residential (RMH), RL and FP to the east; GC and RL to the south; and Open Space (OS), RL, and GC to the west.
3.1.4 Analysis of the Proposed Project
The 2025 Project would reconfigure the planned hotel, residential and related uses in PAs 1 to 8. The Project Site has been planned for the development of a golf course and complementary hotel, residential and commercial land uses and implementation of the SilverRock Resort Project as allowed by the SilverRock Resort Specific Plan would not physically divide an established community for this reason.
As detailed in Table 2-2: Comparative Land Use Summary: Prior Environmental Reviews and the 2025 SilverRock Master Plan, the 2025 Project includes approximately 599 hotel/residential units, 40,000 SF of commercial uses, 55,000 SF banquet/shared facilities, 36 golf holes and a new clubhouse for the Arnold Palmer Classic Course, which would reduce overall development intensity, including fewer residential units, fewer hotel room keys, and less commercial square footage than analyzed in the Previous Assessments. The 2025 Project would remain consistent in terms of use and character with the surrounding golf and residential uses. Therefore, the 2025 Project would not result in any new significant or substantially more severe land use impacts than were identified in the Previous Assessments.
The 2025 Project would not conflict with the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP), which was approved in 2007. The CVMSHCP is a joint regional planning effort of the USFWS, California Department of Fish and Game (CDFG), Bureau of Land Management (BLM), US Forest Service (USFS), National Park Service (NPS), as well as Riverside County and local jurisdictions within the Coachella Valley, including the City of La Quinta. As required by MM BIO-2, a fence was constructed to reduce potential adverse impacts to bighorn sheep to less than significant by precluding access to the Project Site. With the implementation of MM BIO-2, the 2025 Project would not adversely affect any sensitive natural community identified in the General Plan, the CVMSHCP policies and regulations or by the California Department of Fish and Wildlife (CDFW) or US Fish and Wildlife Service (USFWS). The City of La Quinta participates in the CVMSHCP mitigation fee for new development to offset potential biological impacts as discussed further in Section 3.7, Biological Resources, and the 2025 Project remains subject to the CVMSHCP fee.
Land use and planning impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the Project, new information, or changes to the circumstances under which the Project will be undertaken.

3.2 POPULATION AND HOUSING
3.2.1 Thresholds
a. Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
b. Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere?
c. Displace substantial numbers of people, necessitating the construction of replacement housing?
3.2.2 Summary of Findings in Previous Assessments
Previous Assessments found that development of the Project would allow land uses that are consistent with the General Plan Land Use designations and as permitted by the approved Specific Plan. The Specific Plan allows for timeshares, hotels, resort casitas, and privately owned residential units. The prior Addenda discussed that these units may typically be occupied on a seasonal basis, which is typical for privately owned units in resort communities in the Coachella Valley. The Previous Assessments concluded the project would not induce substantial growth in the area. Previous Assessments identified that the proposed development intensities would result in fewer units, hotel keys and commercial space when compared to what is permitted by the Specific Plan. Previous Assessments identified that the reduction in intensity of land uses would generate fewer visitors to the Specific Plan Area. The 2035 General Plan growth projections accounted for the Specific Plan.
Accordingly, no new expansion of existing utility or infrastructure improvements would be needed.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to population and housing. All impacts remained less than significant.
3.2.3 Existing Conditions
The California Department of Finance (DOF) annually updates the latest population and housing numbers. As of January 1, 2025, DOF estimates that the City has a population of approximately 38,796 residents and 24,700 housing units.3 The Project Site does not contain any habitable residential units nor contains anyone living on the site.
3.2.4 Analysis of Proposed Project
The Project Site was approved for the development of hotel and residential units. The 2025 Project includes approximately 599 hotel/residential units, which is less hotel/residential units analyzed in the Previous Assessments. Of those 599 hotel/residential units, there would be 154 hotel units and 3 California Department of Finance. “E-5 Population and Housing Estimates for Cities, Counties, and the State, 2020- 2025.” Accessed July 2025. https://dof.ca.gov/forecasting/demographics/estimates/e-5-population-and-housingestimates-for-cities-counties-and-the-state-2020-2025/. 43 CLICK HERE to Return to Agenda

192 branded residences. For purposes of assessment in this Addendum, it is assumed that all residential and hotel units would be occupied full time. The 346 hotel units and branded residences would generate a population increase of 976 people.4 The remaining 253 residential units in PA 8 would generate a population increase of 714 people, for a total population increase of 1,690 people.5,6
As mentioned above, the City has a current population of approximately 38,796 residents and 24,700 housing units. The City’s projected 2050 population is 55,836, an increase of 17,040 residents within 25 years.7 The addition of 1,690 people would not represent a substantial increase, representing approximately 9.9 percent of the City’s projected population growth from 2025 to 2050. The City currently has 24,700 housing units. The City’s 2035 General Plan EIR found that at General Plan build out, there would be 31,603 dwelling units at full occupancy within the City, an increase of 6,903 units.8 The 2025 Project’s 599 units would represent approximately 8.7 percent of the growth from 2025 to the General Plan build out.
The 2025 Project’s proposed residential uses would not induce substantial population and housing growth within the City. No existing populations reside within the Project Site nor are there any existing habitable housing units within the Project Site. Therefore, development of the 2025 Project would not displace substantial numbers of people, as the Project Site does not contain existing housing and would not require the construction of replacement housing elsewhere.
Population and housing impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes associated with the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.

3.3 GEOLOGY AND SOILS
3.3.1 Thresholds
a. Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving:
i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42.
ii) Strong seismic ground shaking?
iii) Seismic-related ground failure, including liquefaction? iv) Landslides?
b. Result in substantial soil erosion or the loss of topsoil? c. Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in an onsite or off-site landslide, lateral spreading, subsidence, liquefaction or collapse?
d. Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water?
3.3.2 Summary of Findings in Previous Assessments
Previous Assessments found no evidence of an Alquist-Priolo Zone, or potential active faulting within the City, or the Project Site. Therefore, the potential for surface rupture as a result of fault plane displacement during the design life of the Project Site was determined to be less than significant. As also described in Prior Assessments, there are no active or potential faults within the City. However, geological analyses conducted for the 2035 General Plan indicated the City could experience moderate to very high ground shaking from earthquakes along the San Andreas Fault. Strong ground shaking could result in indirect hazards, such as slope instability, liquefaction, settlement, landslides, and flood inundation. All new buildings in the City are required to reinforce masonry, and new construction must comply with the Uniform Building Code (UBC). Compliance with the UBC would allow structures to resist major earthquakes without collapsing. As identified in MM GEO-1 and MM GEO-2, a comprehensive design level geotechnical evaluation and compliance with applicable building codes would minimize structural damage to buildings and ensure safety in the event of a moderate or major earthquake, respectively. Potential impacts would be reduced to a less than significant level with implementation of MM GEO-1 and MM GEO-2.
Previous Assessments determined the Project Site is not located on a geologic unit that is considered unstable, and liquefaction and ground subsidence due to the lowering of the existing groundwater table is considered unlikely due to the minimum depth of 50 feet below ground surface for groundwater on the site. Previous Assessments found that the Project Site is not within areas with high or moderate liquefaction susceptibility and impacts would be less than significant. The southern and western portions of the Planning Area near the base of steep slopes associated with the Santa 45 CLICK HERE to Return to Agenda

Rosa and San Jacinto Mountains are at risk due to seismically induced slope instability. Lands downslope of mountain slopes and hillsides may be susceptible to risks associated with landslide and rockfall. The western edge of the Project Site has potential for soil slumps and rock fall to occur as it is adjacent to the Santa Rosa Mountains; however, the western portion of the Project Site consists of the existing Arnold Palmer Classic Golf Course and is not designated for additional development. Previous Assessments found that the potential impact to structures from earthquake induced slope instability would be less than significant.
Unconsolidated soils occur in many areas of the City and are subject to erosion, including wind erosion. Previous Assessments identified MM AQ-1 through MM AQ-3 for dust control. Further, as identified in the SilverRock Soil Stabilization Project, Previous Assessments described the incorporation of vegetation to stabilize and avoid the loss of loose soils.9 Thus, impacts related to erosion, including wind erosion would be less than significant.
Previous Assessments also identified that there would be no use of septic tanks or alternative wastewater disposal systems because all uses would be connected to existing sanitary sewer lines.
No impacts related to alternative wastewater disposal systems would occur.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to geology and soils. All impacts remained less than significant with incorporation of MM GEO-1 and MM GEO-2.
Previously Identified Mitigation Measures
MM GEO-1 Prior to the design and construction of any structural improvements, a comprehensive design level geotechnical evaluation shall be prepared that includes 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.
MM GEO-2 All buildings planned as a result of the proposed Project shall be constructed in conformance with the Uniform Building Code (UBC), as adopted by the City of La Quinta.
9 At the time the 2006 Addendum was being prepared, the SilverRock Soil Stabilization Project was being implemented to avoid the loss of loose soils in the Specific Plan Area. The SilverRock Soil Stabilization Project included stabilizing approximately 245 acres of undeveloped land within the Specific Plan Area with vegetation. The stabilization project involved minor grading, clearing and grubbing, planting of barley seed and supplying temporary irrigation in order to grow the seed for approximately 3 weeks. Once the barley was established the irrigation was removed and the barley would stabilize the soil together for 2 to 3 years. This was done as a dust mitigation measure until the site is completely developed.

3.3.3 Existing Conditions
The City consists of residential, resort, and commercial development surrounded by hillside and mountain open space areas. Most of the land within the City has been developed with a few undeveloped infill lots located throughout the urbanized area.
As detailed in Section 2: Project Description, the Project Site is fully graded and is developed with the Arnold Palmer Classic Golf Course, the Ahmanson House, and partially constructed buildings.
A Technical Background Report for the Safety Element of the La Quinta 2035 General Plan was completed in 2010.10 The report identified earthquake-triggered geologic effects including ground shaking, surface fault rupture, landslides, liquefaction, subsidence, and seiches. Seismic hazards include areas susceptible to earthquake-induced slope instability and liquefaction. Geological hazards identified within the City in the 2035 General Plan EIR included landslides, slope instability, compressible, collapsible, or expansive soils, soil corrosivity, ground subsidence, erosion, and windblown sand. Potential geology and soils hazards identified on the Project Site include liquefaction, landslides, slope instability, and ground subsidence. No Alquist-Priolo Zones, or evidence of active or potentially active faulting have been identified within the City.
3.3.4 Analysis of Proposed Project
The 2025 Project would develop hotel, residential, commercial, and related uses in PAs 1 to 8. The Project Site has been planned for the development of a golf course and complementary hotel, residential and commercial land uses. As detailed in Table 2-2, the 2025 Project includes approximately 599 hotel/residential units, 40,000 SF of commercial uses, 55,000 SF banquet/shared facilities, 36 golf holes and a new clubhouse for the Arnold Palmer Classic Course, which would reduce overall development intensity, including fewer residential units, fewer hotel room keys, and less commercial square footage than analyzed in the Previous Assessments.
There is no evidence of an Alquist-Priolo Zone, or active or potential active faulting encountered anywhere within the boundaries of or near the Project Site. Therefore, the potential for surface rupture as a result of fault plane displacement during the design life of the 2025 Project would be less than significant.
Although there are no active or potential faults within the City, geological analyses conducted for the 2035 General Plan indicate that the City could experience moderate to very high ground shaking from earthquakes along the San Andreas Fault. Strong ground shaking can result in indirect hazards, such as slope instability, liquefaction, settlement, landslides, and flood inundation. All new buildings in the City are required to reinforce masonry. Additionally, new construction must comply with the UBC, and compliance with the UBC would allow structures to resist major earthquakes without collapsing, 10 City of La Quinta.

even if structural damage occurs.11 The 2025 Project would be designed in compliance with a comprehensive design level geotechnical evaluation and adherence to applicable building codes (as identified in MM GEO-1 and MM GEO-2) to minimize structural damage to buildings and ensure safety in the event of a moderate or major earthquake and reduce this potential impact to a less than significant level.
The Project Site is not located in areas with high or moderate liquefaction susceptibility because the groundwater level found at the Project Site is lower than 50 feet below ground surface (bgs). Impacts would be similar to impacts identified in the Previous Assessments resulting in less than significant impacts.
Areas at risk due to seismically induced slope instability occur within the southern and western portions of the Planning Area near the base of steep slopes associated with the Santa Rosa and San Jacinto Mountains. Lands downslope of mountain slopes and hillsides may be susceptible to risks associated with landslides and rockfall. The 2025 Project is not located in areas with very high, high, or moderate earthquake-induced slope instability. The western edge of the Project Site is located adjacent to the base of the Santa Rosa Mountains, where soil slumps and rock falls occur. This area of the Project Site contains the existing Arnold Palmer Classic Golf Course and is not designated for development. As such, the potential impact to structures from earthquake induced slope instability would be less than significant.
Unconsolidated soils occur in many areas of the City and are particularly subject to erosion, including wind erosion. Erosion can result in loss of topsoil and diminish soil productivity. A majority of the City is located within an active wind erosion zone. The 2025 Project would continue to adhere to the mitigation measures related to erosion and dust control for the Project Site that were identified in Previous Assessments, MM AQ-1 through MM AQ-3. Therefore, impacts related to erosion would be less than significant.
The Project Site is not within a geologic unit that is considered unstable, and ground subsidence due to the lowering of the existing groundwater table is considered unlikely as the groundwater table is a minimum of 50 feet below the ground surface on the site. A portion of the Coachella Canal within the Arnold Palmer Classic Golf Course experienced localized subsidence due to its location atop two different types of ground materials: bedrock and alluvial soils. These materials settle at different rates over time, causing uneven ground movement that led to the sinking of the canal in certain areas.
To address this issue, the Coachella Valley Water District (CVWD), in coordination with the City of La Quinta, implemented a canal realignment project in 2014. The project involved constructing a new, parallel segment of the canal approximately 4,600 feet in length to bypass the unstable section. This realignment restored the full conveyance capacity of the canal and eliminated the subsidence11 City of La Quinta. 2035 La Quinta General Plan EIR. 48 CLICK HERE to Return to Agenda

related deficiencies. Construction was completed by September 2014. The 2025 Project will not impact any portion of the realigned canal.
The 2025 Project would not include the use of septic tanks or alternative wastewater disposal systems, as it would connect to existing sanitary sewer. As such, no impacts would occur with the implementation of the Project.
Geology and soil impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant with the incorporation of MM GEO-1, MM GEO-2, and MM AQ-1 through MM AQ-3. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken. 49 CLICK HERE to Return to Agenda

a. Violate any water quality standards or waste discharge requirements? b. Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of preexisting nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)?
c. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of stream or river, in a manner, which would result in substantial erosion or siltation on or off site?
d. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner, which would result in flooding on or off site? e. Create or contribute runoff water which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff? f. Otherwise substantially degrade water quality?
g. Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? h. Place within a 100-year flood hazard area structures which would impede or redirect flood flows?
i. Expose people or structures to a significant risk of loss, injury, or death involving flooding, including flooding as a result of the failure of a levee or dam? j. Inundation by seiche, tsunami, or mudflow?
3.4.2 Summary of Findings in Previous Assessments
The Previous Assessments found that construction and operation of the project could result in potentially significant erosion, runoff, and water quality impacts. However, implementation of MM W-2, MM W-3, MM W-5, and MM W-8 would reduce construction and operation erosion runoff and water quality impacts to less than significant levels. MM W-2 would ensure that water trucks are used during construction for dust control; MM W-3 would ensure the development of a hydrology master plan prior to issuance of grading permits to ensure that proposed storm drainage and hydrologic improvements would conform to applicable regulations; MM W-5 would ensure the development of a Storm Water Pollution Prevention Program (SWPPP) to develop Best Management Practices (BMPs) that would reduce erosion, runoff, and water quality impacts to acceptable threshold levels; and MM W-8 would ensure that the design of the project would incorporate proper engineering controls to accommodate design year storms that would incorporate filtration systems and protect groundwater or surface water runoff.
Domestic and irrigation water is provided throughout La Quinta and the eastern Coachella Valley by the Coachella Valley Water District (CVWD). The main source of potable water provided to the City is 50 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-15 SilverRock Resort Project Addendum September 2025
from an underground aquifer, known as the Whitewater River Subbasin, beneath the valley floor.
Irrigation water is supplied from this same aquifer and from the Colorado River via the Coachella Canal and is consumed generally in the area from Indio and La Quinta south to the Salton Sea. Water consumption related to the project’s residential, commercial and irrigation uses could potentially result in significant water use.
A Water Supply Assessment (WSA) and Water Supply Verification (WSV) approved by the Coachella Valley Water District (CVWD) for the project confirmed that CVWD had sufficient water supplies available to meet the demands of the project. Additionally, the Project would incorporate MM W-1, MM W-4, and MM W -7 to further minimize water use, resulting in less than significant water use impacts. MM W-1 would require the use of non-potable sources of water for irrigation at such time it becomes available to the Project Site; MM W-4 would require drought tolerant landscaping as feasible to reduce water consumption; and MM W-7 would require a Golf Course Management Plan to reduce irrigation runoff and percolation into the groundwater basin.
At the time of the 2002 MND, there were groundwater wells within the site and MM W-6, which required abandoning groundwater wells no longer in use was implemented. No groundwater wells exist on the site.
The Project Site is not within a 100-year flood hazard area, nor near a large body of water that would be able to cause a significant seiche, tsunami or mudflow to the site. The General Plan considers the Coachella Canal, which bisects the Project Site, as a levee. However, the General Plan EIR confirms that no significant inundation would occur if the canal banks fail.
No new information or changed circumstances was identified in the Previous Assessments that resulted in new or more severe impacts related to water. All impacts remained less than significant with the incorporation of MM W-1 through MM W-8.
Previously Identified Mitigation Measures
MM W-1 At such time that non-potable water sources become available to the Project Site, the Project shall be connected to this resource and utilize the non-potable water for irrigation purposes.
MM W-2 During construction activities, water trucks are to acquire water from non-potable water sources, such as reclaimed water and/or canal water.
MM W-3 A hydrology master plan shall be prepared for the Project Specific Plan. Further, a hydrology study shall be prepared for the hydrology master plan and submitted to the City of La Quinta for approval prior to the issuance of grading permits. This study shall demonstrate that the Project would construct storm drainage and hydrologic improvements, such as on-site stormwater retention basins, that conform to the 51 CLICK HERE to Return to Agenda

City‘s master hydrology and storm drain improvement program as well as implement regional and local requirements, policies, and programs.
MM W-4 Drought tolerant landscaping shall be utilized as a means of reducing water consumption.
MM W-5 Prior to the initiation of any construction activity on the Project Site, a Notice of Intent (NOI) to conduct construction activities under the general NPDES construction permit shall be filed. Under the conditions of this NPDES permit a Storm Water Pollution Prevention Plan (SWPPP), and Monitoring Plan are required. The SWPPP shall include Best Management Practices (BMPs) in compliance with the NPDES program requirements.
MM W-6 Any 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.
MM W-7 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.
MM W-8 Design of new roads, golf courses, man-made ponds, common landscape areas, storm water 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.
3.4.3 Existing Conditions
The Project Site is developed with the Arnold Palmer Classic Golf Course, Ahmanson House, partially developed hotel and residential buildings, and has been mass graded and vegetated to minimize soil erosion. The hydrology design includes the use of the golf course as part of the storm water control system. The golf course has sufficient capacity to accommodate existing on-site drainage quantities.
On-site drainage systems have been constructed since the development of the site in 2002.
A major storm drain exists along the northerly property frontage within Avenue 52 which extends 2,200 feet to the Calle Rondo storm drain from the northwesterly corner of the site to a point just past the Avenue 52/SilverRock Way entrance and then back onto the resort property into the second golf course envelope (Planning Area 8).

The Arnold Palmer Golf Course is irrigated using Coachella Canal water. The Specific Plan Area is not located within a 100-year or 500-year floodplain.12
3.4.4 Analysis of Proposed Project
Construction and operation of the 2025 Project could potentially result in erosion, runoff, and water quality impacts. Although the 2025 Project involves reduced development intensity compared to the land uses analyzed in the Previous Assessments, these impacts may still occur. However, with the incorporation of mitigation measures MM W-2, MM W-3, MM W-5, and MM W-8, potential erosion, runoff, and water quality impacts would be reduced to less than significant levels.
As discussed above, a WSA and WSV were developed for the project analyzed in the Previous Assessments and confirmed that CVWD would be able to provide a sufficient amount of water for the demands of the original, more intense project. The 2020 Coachella Valley Regional Urban Water Management Plan confirms that CVWD has adequate water supplies to 2045 under normal, single, and multiple dry years.13
The water demand estimate for the SilverRock Resort Project in the 2006 Water Supply Assessment (WSA) approved for the project was approximately 2,361 acre-feet per year. The estimated water demand for the 2025 Project is approximately 2,376 acre-feet per year.14 This potable water demand is less than one percent greater than the demand estimate in the approved WSA. This incremental increase does not represent a substantial increase in water demand for the project. The 2025 Project would have a reduced development intensity, further reducing water demand. Additionally, the project would incorporate MM W-1, MM W-4, and MM W-7 to further minimize water use, resulting in less than significant water use impacts.
As mentioned above, the Project Site is not located within a 100-year flood zone, nor would the Project Site be significantly impacted by a levee/dam, or seiche, tsunami or mudflow from an open body of water.
Water impacts associated with the 2025 Project would be less intense than those identified in the Previous Assessments and would be less than significant with the incorporation of MM W-1 to MM W-5 and MM W-7 to MM W-8 and applicable regulatory requirements. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.

3.5 AIR QUALITY
3.5.1 Thresholds
a. Conflict with or obstruct implementation of the applicable air quality plan? b. Violate any air quality standard or contribute substantially to an existing or projected air quality violation?
c. Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)?
d. Expose sensitive receptors to substantial pollutant concentrations? e. Create objectionable odors affecting a substantial number of people?
3.5.2 Summary of Findings in Previous Assessments
The Previous Assessments concluded that the development of the Project Site would not conflict with the applicable air quality plan, because all construction and operational activities would remain below the South Coast Air Quality Management District’s (“SCAQMD”) recommended daily thresholds for all criteria pollutants. The Previous Assessments also found that previous projects would not violate any air quality standards with the incorporation of MM AQ-1 through MM AQ-13, listed below. MM AQ-1 to MM AQ-3 require dust control, MM AQ-3 also included measures for efficient construction traffic management, MM AQ-4, MM AQ-5, and MM AQ-7 through MM AQ-10 require the use of energy efficient materials and appliances, MM AQ-6 implemented trees for shading, MM AQ-11 and MM AQ-12 require expansion of transit and more efficient on-site circulation, and MM AQ-13 requires the use of low VOC paints.
Construction and operational air quality modeling previously conducted in the Previous Assessments were based on the expected location, size, and development of the Project Site.
According to SCAQMD, if an individual project results in air emissions of criteria pollutants that are below SCAQMD’s recommended daily thresholds for project-specific impacts, then the project would not result in a cumulatively considerable net increase of these criteria pollutants. The Previous Assessments concluded that emissions resulting from construction and operations were not projected to exceed any air quality emission significance thresholds with implementation of AQ-1 through 13, described above. Therefore, the Project would not result in a cumulative considerable net increase of any criteria pollutant for which the Project Site region is designated as being nonattainment.
The Project Site is developed with the Arnold Palmer Classic Golf Course and Ahmanson House, with the nearest sensitive receptors being the surrounding residential and golf communities to the north, east, and south. The nearest sensitive receptors were located in PGA West and the Hideaway residential and golf communities, approximately 125 feet and 150 feet to the south and east, respectively, of the boundaries of the Project Site. The localized significance thresholds (LSTs) were 54 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-19 SilverRock Resort Project Addendum September 2025
used to address potential air quality impacts to the nearby residents and neighborhoods surrounding the Project Site. The land uses included in the Previous Assessments were found to be typical of uses found throughout the City and were not found to generate on-site construction or operational emissions in excess of the site-specific LSTs. None of the uses were found to have any special concern with regards to harmful odorous pollutants that would negatively affect sensitive receptors located within the vicinity of the Project Site.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to air quality. All impacts remained less than significant with the incorporation of mitigation measures identified in the Previous Assessments.
Previously Identified Mitigation Measures
MM AQ-1 Construction equipment shall be phased and operated in a manner to ensure the lowest construction-related pollutant emission levels practical, and shall require the use of water trucks, temporary irrigation systems and other measures which will limit fugitive dust emissions during site disturbance and construction.
MM AQ-2 Air quality control measures identified in the Coachella Valley PM10 State Implementation Plan (SIP) shall be implemented.
MM AQ-3 A PM10Management Plan for construction operations shall be submitted prior to the issuance of grading permits. The plan shall include dust management controls such as:
• Water site and equipment morning and evening
• Spread soil binders on site, unpaved roads, and parking areas • Re-establish ground cover on construction site through seeding and watering • Pave construction roads, where appropriate
• Operate street-sweepers on paved roads adjacent to site The following measures shall be implemented to reduce construction related traffic congestion:
• Configure construction parking to minimize traffic disturbance • Minimize obstruction of through-traffic lanes
• Provide flag person to ensure safety at construction sites, as necessary • Schedule operations affecting roadways for off-peak traffic hours • Provide rideshare incentives to construction personnel MM AQ-4 Timeshare and golf facility construction shall utilize solar or low emission water heaters to reduce natural gas consumption and emissions.

3.5.3 Existing Conditions
The Project Site is located within the Salton Sea Air Basin within the jurisdiction of the SCAQMD. The City of La Quinta is subject to high intensity wind events year-round. During fall and winter months, high-pressure systems from the north can conflict with low-pressure systems from the south, and create a condition known as the Santa Ana winds, which can blow for multiple days at high speeds.
These strong winds sweep up, suspend and transport large quantities of sand and dust, reducing visibility, damaging property, and constituting a significant health threat.
The Federal and State Clean Air Act standards are the thresholds by which regional ambient air quality is measured. In the Coachella Valley air quality has exceeded state and federal standards for ozone and particulate matter. Areas where air pollution levels persistently exceed the state or national ambient air quality standards may be designated "nonattainment." For evaluation purposes, the SCAQMD territory is divided into 38 source receptor areas (SRAs). These SRAs are designated to provide a general representation of the local meteorological, terrain, and air quality conditions within 56 CLICK HERE to Return to Agenda

the particular geographical area. The Project Site is within SRA 30, Coachella Valley.15 The nearest air monitoring station SCAQMD operates is located at 46990 Jackson Street in the City of Indio and monitors O3, PM10, and PM2.5. The nearest monitoring station to the Project Site that monitors NO2 is the Palm Springs Fire Station located at 590 Racquet Club Road in the City of Palm Springs. The Coachella Valley portion of the Salton Sea Air Basin is currently designated as being in nonattainment for the federal ozone and PM10 and nonattainment for the State ozone and PM10.
As detailed in Section 2: Project Description, the Project Site consists of areas that have been previously graded, developed, or partially developed as shown in Figure 2-3: Project Site Aerial Photographs. SilverRock Park is located in the northwest; the Arnold Palmer Classic Golf Course, Ahmanson House, and a series of partially constructed buildings associated with the previous approvals are located in the western portion of the site, as described in Table 2-1: Partially Constructed Buildings, above.
3.5.4 Analysis of Proposed Project
SCAQMD is responsible for controlling emissions, primarily from stationary sources. SCAQMD, in coordination with the Southern California Association of Governments (SCAG), is also responsible for developing, updating, and implementing the Air Quality Management Plan (AQMP) for the air basins. An AQMP is a plan prepared and implemented by an air pollution district for a county or region designated as being in nonattainment of the National Ambient Air Quality Standards (NAAQS) or California Ambient Air Quality Standards (CAAQS). SCAQMD adopted the Final 2022 Air Quality Management Plan (2022 AQMP) on December 2, 2022.16 The AQMP includes transportation control measures developed by SCAG from its 2020−2045 Regional Transportation Plan / Sustainable Communities Strategy (2020−2045 RTP/SCS), as well as the integrated strategies and measures needed to meet the NAAQS. The AQMP demonstrates the attainment of the 1-hour and 8-hour ozone NAAQS, as well as the latest 24-hour and annual PM2.5 standards.
Projects considered to be consistent with the Air Quality Management Plan (AQMP) would not interfere with the attainment of the air quality levels identified in the AQMP because this growth is included in the projections utilized in the formulation of the AQMP. A project is consistent with the AQMP, in part, if it is consistent with the population, housing, and employment assumptions that were used in the development of the AQMP.

It should be noted that the Specific Plan was accounted for in the growth projections in the 2035 General Plan.17 As shown in Table 2-2: Comparative Land Use Summary: Prior Environmental Reviews and the 2025 SilverRock Master Plan, the 2025 Project would result in a reduced development intensity. As detailed in Section 3.2: Population and Housing, the 2025 Project would increase the population and housing well within the growth projections within the City.
As discussed further below, emission from construction and operation of the proposed Project would fall below the applicable thresholds with the implementation of MM AQ-1 through MM AQ-13.18 Therefore, the 2025 Project would not conflict with or obstruct the implementation of an applicable air quality plan.
Construction
The construction emissions for the 2025 Project were calculated using construction emission factors contained in the California Emissions Estimator Model (CalEEMod) model (Appendix A). The emission calculations assumed the use of standard construction practices, such as compliance with SCAQMD Rule 403 (Fugitive Dust), to minimize the generation of fugitive dust, SCAQMD Rule 403.1 (Supplemental Fugitive Dust Control Requirements for Coachella Valley Sources), and Rule 1113 (Architectural Coatings). Compliance with Rule 403, Rule 403.1, and Rule 1113 is mandatory for all construction projects. Specifically, Rule 403 and Rule 403.1 require watering of exposed surfaces and unpaved roads three times daily, which is estimated to reduce fugitive dust emissions of particulates less than 10 microns in diameter (PM10) and particulates less than 2.5 microns in diameter (PM2.5) by 61 percent, requires a fugitive dust control plan for construction projects, and requires reductions in the volatile organic compounds (VOC) content of coatings. Additionally, during construction, all off-road construction equipment greater than 50 horsepower must meet USEPA Tier 3 emission standards with Level 3 DPF to minimize emissions of NOx associated with diesel construction equipment.
As discussed above, construction of the 2025 Project would include two phases – Phase I and Phase II. Phase I would include the development of PAs 1 to 7 and Phase II would include the development of PA 8. Phase I is anticipated to occur over the course of seven years, with a start in November 2026 and completion by April 2033. Table 3.5-1: Project Construction Schedule provides estimates of the dates and durations of each of the activities that will take place during construction, as well as a brief description of the scope of work. Future dates represent approximations based on the general Project timeline and are subject to change, pending unpredictable circumstances that may arise. It is important to note Project delays that affect the corresponding time period in which construction activities would occur compared to the analysis time period would result in lower emissions due to newer equipment, regulatory requirements, and greater engine efficiencies. Therefore, the reported 17 City of La Quinta. 2035 La Quinta General Plan. Economic Development. 2013. p.

The estimated maximum daily emissions were estimated based on the construction schedule provided in Table 3.5-1 and are presented in Table 3.5-2: Highest Daily Construction Pollutant Emissions. These estimates are based on the expected location, size, and development of the proposed Project uses.

overlap. Therefore, the input values used in this analysis are considered conservative, as most equipment operates only a fraction of each workday and many of the activities would not overlap on a daily basis. As shown in Table 3.5-2, construction activities associated with the development of the 2025 Project would not result in an exceedance of VOC, nitrogen oxides (NOx), carbon monoxide (CO), sulfur oxide (SOx), PM10, and PM2.5 thresholds. Impacts with regard to these air pollutants would be less than significant, even when assuming overlapping construction activities which are unlikely to occur. Potential construction emission impacts on sensitive receptors are analyzed below.

Operation
Operational emissions were estimated using the CalEEMod software, which was used to forecast the daily regional emissions that would occur during long-term Project operations.
Operation of the 2025 Project has the potential to generate criteria pollutant emissions through vehicle trips traveling to and from the Project Site. In addition, emissions would result from area sources on site, such as landscaping equipment and use of consumer products. Area-source emissions are based on landscaping equipment and consumer products (including paint) usage rates provided in CalEEMod.
The estimated operational emissions based on development of all the proposed land uses are presented in Table 3.5-3: Operational Emissions. As shown in Table 3.5-3, the 2025 Project’s operational emissions would not exceed regional daily VOC, NOx, CO, SOx, PM10, and PM2.5 thresholds. Therefore, daily operational emissions generated by the proposed Project would be less than significant.

As shown in Table 3.5-3, operational emissions for the 2025 Project do not exceed the SCAQMD thresholds of significance. According to SCAQMD, if an individual project results in air emissions of criteria pollutants that are below the SCAQMD’s recommended daily thresholds for project-specific impacts, then the project would not result in a cumulatively considerable net increase of these criteria pollutants. By applying SCAQMD’s cumulative air quality impact methodology, implementation of the 2025 Project would not exceed the thresholds for these criteria air pollutants, and no significant cumulative impacts would occur. Therefore, the 2025 Project would not result in a cumulatively considerable net increase of criteria air pollutants. and would not result in a cumulative considerable net increase of any criteria pollutant for which the 2025 Project region is designated as in non-attainment.
Sensitive Receptors
SCAQMD considers a sensitive receptor to be a person in the population who is particularly susceptible to health effects due to exposure to an air contaminant. The nearest sensitive receptors are located in PGA West and the Hideaway residential and golf communities, approximately 125 feet and 150 feet to the south and east, respectively of the boundaries of the proposed Project Site.
Localized Significance Threshold
The localized significance thresholds (LSTs) used in this analysis address whether there are potential impacts to residents and neighborhoods located around and near the Project Site. The 2025 Project assumed up to 3 acres was disturbed each day. The allowable mass-rate emissions were determined using the specified thresholds for a 3-acre site at a distance of 50 meters (150 feet) from the nearest sensitive receptor as determined by SCAQMD.
The local significance thresholds are based on the SCAQMD’s Final Localized Significance Threshold Methodology (LST Methodology)19 guidance document for short-duration construction activities. 19 SCAQMD. Final Localized Significance Threshold (LST) Methodology. July 2008. Accessed March 2025. http://www.aqmd.gov/docs/default-source/ceqa/handbook/localized-significance-thresholds/final-lstmethodology-document.pdf?sfvrsn=2. 61 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-26 SilverRock Resort Project Addendum September 2025
The SCAQMD recommends the evaluation of localized air quality impacts to sensitive receptors in the immediate vicinity of the Project site because of construction activities.
The LST Methodology provides lookup tables of emissions that are based on construction projects of up to five acres in size. The threshold is a daily emissions level and thus the acreage is an approximation of the daily disturbed area.20 As such, the ambient conditions for a 3.0-acre site within SRA 30 were used for ambient conditions in determining appropriate threshold levels.
The construction and operation analysis for LSTs for the proposed Project are shown in Table 3.5-4:
Localized Construction and Operational Emissions. As shown in Table 3.5-4, the on-site emissions incorporate the required regulations for compliance with Rule 403 (Fugitive Dust), Rule 403.1, and Tier 3 engines for off-road construction equipment. The construction of the proposed Project would not generate on-site emissions in excess of the site-specific LSTs for NOx, CO, PM10, and PM2.5. Given this, the 2025 Project would result in a less than significant impact on sensitive receptors located north, east, and south of the Specific Plan Area.
According to the SCAQMD, while almost any source may emit objectionable odors, some land uses will be more likely to produce odors because of their operation. Land uses that are more likely to produce odors include agriculture, chemical plants, composting operations, dairies, fiberglass molding, landfills, refineries, rendering plants, rail yards, and wastewater treatment plants. The proposed Project does not contain any active manufacturing activities. Therefore, objectionable odors would not be emitted by the proposed Project.

3.6.1 Thresholds
a. Exceed the capacity of the existing circulation system, based on an applicable measure of effectiveness (as designated in a general plan policy, ordinance, etc.), taking into account all relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? b. Conflict with an applicable congestion management program including, but not limited to level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? c. Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? d. Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? e. Result in inadequate emergency access?
f. Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)?
3.6.2 Summary of Findings in Previous Assessments
The Previous Assessments found that the development of the planned golf courses and resort uses were consistent with the General Plan land use designations for the site. Based on trip generation rates for the planned uses, it was estimated that the land uses analyzed in the Previous Assessments would generate a total of approximately 20,020 daily trips with 1,420 AM peak hour trips and 1,830 PM peak hour trips, if internal trips are not accounted for. This worst case estimate overstates actual trip generation because it double counts some trips as many of the resort hotel, golf and retail village trips would be between these different uses and would stay within the Specific Plan Area for this reason.
The City’s General Plan established the level of service (LOS D) as the City’s minimum level of service for intersections. The site is bounded by Jefferson Street, Avenue 52, and Avenue 54. The 2035 forecasted intersection LOS during the peak season based on the recommended intersection improvements from the 2035 General Plan would result in LOS C during both peak hour periods at Washington Street and Avenue 52; LOS C during the AM Peak Hour and LOS D during the PM Peak Hour at Jefferson Street and Avenue 52; and LOS B during both peak hour periods with a new traffic signal at Jefferson Street and Avenue 54. It should be noted that a new traffic signal has been installed at the SilverRock Way and Avenue 52 intersection as outlined in MM TRANS-1, resulting in less than significant impacts to LOS.
The Previous Assessments determined that the project would not impact air traffic as it is not located in an area that is adjacent to an airport. The nearest airport was approximately 7 miles away from the Project Site.

Meridian Consultants 3.0-29 SilverRock Resort Project Addendum September 2025
The Previous Assessments concluded that development of the project would have less than significant impacts related to hazards and safety from design features (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment), inadequate emergency access to nearby uses, insufficient parking capacity on site or off site, and hazards or barriers for pedestrians or bicyclists. The 2002 MND also concluded that the 2002 MND Project would have no impacts in regard to conflicts with adopted policies supporting alternative transportation (e.g., bus turnouts, bicycle racks) and rail, waterborne, or air traffic impacts.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to transportation and circulation. All impacts remained less than significant with mitigation identified in the Previous Assessments.
Previously Identified Mitigation Measures
MM TRANS-1 A traffic signal shall be installed at the Project entrance and Avenue 52, the Project entrance and Jefferson Street and at the intersection of Avenue 54 and Jefferson Street when and if they are warranted. The developer of the site shall be responsible for payment of a fair share of the cost of installing these signals.
3.6.3 Existing Conditions
A traffic impact analysis (TIA) was prepared for the 2035 General Plan to assess the existing roadway network, collect data on and measure the level of use and service along the existing roadways in the General Plan study area.
The City has developed and maintains an extensive arterial roadway network, serving both local and inter-city traffic. The City road network has been built essentially along a north-south grid with interconnections with major arterials passing through adjacent jurisdictions.22 The Project Site is bounded by Jefferson Street, Avenue 52, and Avenue 54.
Jefferson Street is oriented in a north-south direction and consists of three lanes in each direction. It is classified as a Major Arterial north of Avenue 54 and as a Modified Secondary Arterial between Avenue 58 and Avenue 62. Jefferson Street provides access to State Highway 111, southern parts of the City and to Interstate 10 north of City limits.
Avenue 52 is oriented in an east-west direction and is classified as a Primary Arterial throughout the City and the City’s Sphere of Influence.
Avenue 54 is an east-west street consisting of two lanes in each direction between Jefferson Street to east of Monroe Street.

As discussed above, a portion of MM TRANS-1 has already been implemented with the installation of a traffic signal at the intersection of SilverRock Way and Avenue 52. The 2035 General Plan projected that the intersection of Jefferson Street and Avenue 54 would operate at Level of Service (LOS) B with a traffic signal in place. Currently, this intersection remains unsignalized. MM TRANS-1 will be implemented as warranted to ensure that surrounding intersections continue to operate at LOS D or better.
The 2025 Project would not impact air traffic as it is not located in an area that is adjacent to an airport. The nearest airport was approximately 7 miles away from the Project Site.
The 2025 Project would not substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses because the circulation pattern follows a similar circulation route planned in the Specific Plan. It should be noted that the 2025 Project proposes a minor re-alignment of internal roadways, including portions of SilverRock Way and Ahmanson Lane.
This adjustment would shift the road away from its current location between the proposed public golf clubhouse and the first hole of the Arnold Palmer Golf Course, rerouting it around the clubhouse to 66 CLICK HERE to Return to Agenda

improve pedestrian safety. As this modification involves internal circulation and does not affect external roadways, it would not introduce new hazards related to roadway design or circulation. It would, however, improve safety on-site, which represents a beneficial impact. Development of all roads and pedestrian facilities would comply with applicable City standards. The 2025 Project would adhere to the Project Site’s land use designations and would have a lower development intensity compared to the Previous Assessments, resulting in no conflicts with applicable transportation regulations and less than significant impacts.
Transportation and circulation impacts associated with the 2025 Project would be similar to those identified in the Previous Assessment and would be less than significant with the implementation of TR-1. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the Project, new information, or changes to the circumstances under which the Project will be undertaken.

3.7.2 Summary of Findings in Previous Assessments
Previous Assessments identified that the flat portion of the Project Site had historically been used for agricultural purposes and the majority of this portion of the site consisted of disturbed non-native vegetation. Five (5) vegetation communities were identified on the site including disturbed vegetation, agricultural lands, tamarisk groves, desert saltbush scrub, and mesquite hummocks.
A series of biological surveys were conducted on the Project Site between 1999 and 2002. Focused surveys for Coachella Valley fringe-toed lizard, flat-tailed horned lizard, Coachella Valley roundtailed ground squirrel, Palm Springs pocket mouse, Coachella Valley grasshopper and peninsular bighorn sheep were conducted based on the recommendation of the United States Fish and Wildlife Service (USFWS) and California Department of Fish and Game (CDFG) (now referred to as California Department of Fish and Wildlife (CDFW)) in 1999. None of these species were observed on the site.
All other sensitive species were surveyed for in conjunction with these surveys or the previous surveys.
One species of special concern, the Loggerhead shrike, was observed on the site during the 1999 surveys. A second special-status species, the black-tailed gnatcatcher, was observed on an adjacent site during 1999 surveys and, for this reason, was considered to have a high potential to be present on the Project Site. Suitable habitat for these two (2) species comprised very few acres and the Project Site was not likely to sustain a large population of either species. Previous Assessments determined the potential impact to these two (2) bird species was not significant. 68 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-33 SilverRock Resort Project Addendum September 2025
The 2002 MND identified that the Santa Rosa Mountains historically provided habitat for peninsular bighorn sheep, a state- and federally listed endangered species. Focused surveys performed in 1999 found no evidence of bighorn sheep in the vicinity of the 2002 MND Project Site. Essential habitat of the peninsular bighorn sheep in this area was defined by the USFWS to include the Santa Rosa Mountains down to the toe-of-slope. As no development was proposed to infringe above the toe-ofslope, no portion of the Project Site would have been developed in the essential peninsular bighorn sheep habitat. However, the Previous Assessments identified mitigation measures to protect the bighorn sheep. MM BIO-1 to MM BIO-10 were adopted to reduce potential impacts to bighorn sheep to less than significant levels. MM BIO-1 to MM BIO-10 included incorporating a buffer and fencing system into the project to prevent the Bighorn Sheep and other wildlife from entering the site, restricting access by pets into the adjacent open space area, and minimizing indirect impacts to this open space area from lighting, glare, noise, and harmful landscaping or chemicals. Construction and design features, including native landscaping, non-glare glass, controlled lighting, and restricted pesticide use are required by these mitigation measures.
Seven (7) special-status plant species were identified as known to occur in the general vicinity of the Project Site. A special-status plant survey was completed on the Project Site in April 2000. No individuals or populations of Coachella Valley milk-vetch were found during these focused surveys.
In addition, no other special-status plant species were observed on the site during these surveys.
One special-status vegetation community, known as mesquite hummocks, was identified within the Specific Plan Area and impacts to these hummocks were identified as significant. The 2002 MND identified mitigation to reduce this impact to a less than significant level. MM BIO-11 required that prior to any construction or site preparation activities that would impact the 3.4 acres of mesquite hummock, the agency or project developer enter into a Memorandum of Understanding (MOU) with the California Department of Fish and Wildlife and an appropriate non-profit organization whose purpose is to acquire and manage land for the purpose of protecting special status plants and wildlife. The MOU was to provide the organization chosen the financial resources necessary to purchase and manage 3.4 acres of mesquite hummock in the Willow Hole area or in another area where the habitat is contiguous and large preserves already protect much of this habitat type.
Previous Assessments found that the requirements of MM BIO-11 have been fulfilled, as a non-profit organization purchased contiguous mesquite hummock habitat in another area to offset the 3.4 acres of mesquite hummock on-site, resulting in less than significant impacts to mesquite hummocks.
The 2002 MND identified that a total of 5.29 acres of potential wetlands were present on the Project Site. A wetland delineation was completed in August 2000 and identified four (4) potential jurisdictional areas on the 2002 MND Project Site including a system of channels, a swale, and two (2) excavated retention basins.

3.0—Impact Analysis
Meridian Consultants 3.0-34 SilverRock Resort Project Addendum September 2025
The 2002 MND determined that because development of the Project Site had the potential to remove all or some of the potential wetlands on-site and because the area was regulated by state and federal resource agencies, this loss could be considered a significant impact without the incorporation of mitigation measures. With implementation of MM BIO-12, requiring federal and State permits for impacts to these features, impacts would be less than significant.
The Project Site was surrounded on two sides by mostly developed land, consisting of residences, agricultural crops, and fallow or abandoned cropland. The Santa Rosa Mountains borderthe western edge of the Project Site and constitute a large, natural open space area. There was one area adjacent to and east of the Project Site that contained some native scrub habitat at the time the 2002 MND was prepared. This area was not directly connected to any large open spaces and the native habitat adjacent to it was patchy and disjunctive. Subsequently, that area was developed. Therefore, Previous Assessments determined that the Project did not serve as a wildlife movement corridor between large open spaces and potential impacts to wildlife movement were less than significant.
Subsequent to the preparation of the 2002 MND, the Project Site was mass graded. MM BIO-12 was implemented prior to the commencement of on-site grading to mitigate potential impacts to wetland habitat. The majority of the remainder of the site was planted with barley as a dust control reduction measure.
The 2014 Addendum identified that the USFWS and CDFW provided the City a notice about urbanrelated impacts to the peninsular bighorn sheep in February 2014 because the bighorn sheep were using golf resort areas to forage and locate water, requiring the installation of a barrier to sheep access and required the City to provide wildlife agencies with a report with actions to be taken in order to implement the plan. Since that time, the exclusion fence has been constructed.
The 2014 Addendum found that any future development would be subject to compliance with specific goals and measures set forth in the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP). Although the Project Site is not directly within the CVMSHCP Conservation Areas, the Project Site is located adjacent to the Santa Rosa and San Jacinto Mountain Conservation Areas.
Thus, the 2035 General Plan requires the project to incorporate project design features (PDFs) BIO PDF-1, BIO PDF-6 and BIO PDF-9 by ensuring that the developer pay applicable mitigation fees and work to guarantee the safe protection of burrowing owls and migratory birds that may reside on the Project Site. With the incorporation of the PDFs, impacts to biological resources on the Project Site would be reduced to less than significant levels.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to biological resources. All impacts remained less than significant with implementation of MM BIO-1 through MM BIO-12 and with the incorporation of BIO PDFs 1, 6 and 9.

Previously Identified Mitigation Measures
MM BIO-1 A mountain toe-of-slope buffer/mitigation concept plan has been prepared to protect peninsular Bighorn Sheep, and other wildlife, from entering the nonmountainous portion of the site proposed for development. This concept plan illustrates a continuous buffer to the toe-of-slope in areas where development could occur adjacent to the mountain edge. The concept plan delineates the location, acreage and native plant species envisioned for the mitigation area. This plan shall be incorporated into the project design and shall be subject to review by the City prior to the issuance of grading permits. A copy of this mountain toe-of-slope buffer/mitigation concept plan is available for review at the City of La Quinta Community Development Department.
MM BIO-2 If Bighorn Sheep enter into the Project Site, an 8-foot fence (or the functional equivalent) between the development and the hillside shall be constructed. The gaps should be 11 centimeters (4.3 inches) or less. If determined necessary, the City shall construct temporary fencing while permanent fencing is constructed. The fence shall not contain gaps in which Bighorn Sheep can be entangled. If the Department transfer or disposes of any of the property adjacent to the hillside, the Department shall reserve an easement sufficient for the construction of fencing if needed in the future.
MM BIO-3 Dogs shall not be permitted to be loose within the Project area, and shall be kept away from the hillside areas through appropriate signage and fencing, where applicable.
MM BIO-4 Access into the hillside area from the site will be discouraged through the use of signs or barricades, if necessary, unless the access is provided as part of a trail system that is approved by the USFWS and CDFG.
MM BIO-5 A construction plan shall be prepared and provide, to the extent practicable, construction activities that emit excessive noise will be avoided adjacent to the hillside. In addition, during grading and construction activities any blasting or piledriving near the hillside will not occur during the period from January 1 through June
30. MM BIO-6 The final design of the Project shall insure that road and driveways are designed to minimize headlight shine from vehicles onto the hillside.
MM BIO-7 In all areas adjacent to the hillsides, non-glare glass shall be used in new construction. Exterior building lights shall not shine on the hillside. Exterior lighting shall be kept at the safest possible minimum intensity and aimed away from the hillside.
MM BIO-8 The landscape plan shall include only plants that are non-toxic to wildlife. All exotic plans such as tamarisk and fountain grass are prohibited. Existing trees may remain. 71 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-36 SilverRock Resort Project Addendum September 2025
MM BIO-9 All swimming pools located in the Project Site shall be fenced pursuant to City regulations.
MM BIO-10 Efforts shall be made to ensure that all pesticides, fungicides, herbicides, and fertilizers used during the construction and operation of the Project Site will not be harmful to wildlife.
MM BIO-11 Prior to any construction or site preparation activities that would impact the 3.4 acres of mesquite hummock, the agency or 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 3.4 acres of mesquite hummock in the Willow Hole area or in another area where the habitat is contiguous and large preserves already protect much of this habitat type.
MM BIO-12 Prior to the commencement of on-site grading, a 404 permit shall be obtained, if legally required, for alteration of areas under the Army Core of Engineers (ACOE) jurisdiction. In addition, if development activities are to take place within streambeds or drainages under the jurisdiction of the CDFG, a streambed alteration agreement shall first be obtained, if legally required.
Previously Identified Project Design Features
Previously identified project design features from the 2035 General Plan include:
BIO PDF-1 The City shall require payment of Coachella Valley Multiple Species Habitat Conservation Plan mitigation fees prior to issuance of occupancy permits for development projects required to pay such fees.
BIO PDF-6 Prior to the issuance of any ground disturbing permit for qualifying projects in a Conservation Area, the City shall require a protocol complaint survey for Burrowing Owl, in compliance with the MSHCP Section 4.4.
BIO PDF-9 In compliance with the requirements of the Migratory Bird Treaty Act (MBTA), the City shall continue to require that for development projects proposing removal of vegetation between March and August, a qualified biologist shall be retained to determine whether any bird nests or young occur on the site, and if they occur, to provide mitigation measures compliant with the MBTA.
3.7.3 Existing Conditions
The Project Site has been mass graded and contains the Arnold Palmer Golf Course, Ahmanson House, and partially developed hotel and residential buildings from previous approvals. The Arnold Palmer Golf Course is located on the most western portion of the site along the edge of the Santa Rosa Mountains, a known habitat for the peninsular bighorn sheep. There is no riparian habitat 72 CLICK HERE to Return to Agenda

Meridian Consultants 3.0-37 SilverRock Resort Project Addendum September 2025
present on the Project Site. A Bighorn sheep exclusion fence along the toe of slope has been constructed within the Project site.
The City is a signatory and participant for the CVMSHCP. The Project Site is located adjacent to the Santa Rosa and San Jacinto Mountains Conservation Area. The City collects a CVMSHCP fee for applicable projects and collects the fee at permit issuance.
3.7.4 Analysis of Proposed Project
As discussed above, the Previous Assessments incorporated MM BIO-11 and MM BIO-12 before mass grading the entire Project Site, resulting in less than significant impacts to biological resources within the Project Site. Those mitigation measures have now been satisfied and are no longer applicable to project implementation. At the time the 2014 Addendum was prepared, a notice was provided that bighorn sheep were seen grazing on the Project Site, prompting CDFW to require a fence built within a year. The fence has been built and completed. MM BIO-1 and MM BIO-10 are still applicable to the 2025 Project to ensure less than significant impacts to the bighorn sheep.
As the Project Site is located adjacent to the Santa Rosa and San Jacinto Mountain Conservation Areas, the General Plan requires the 2025 Project to incorporate BIO PDF-1, BIO PDF-6 and BIO PDF9 by ensuring that the developer pays all applicable mitigation fees not previously paid and ensuring the safe protection of burrowing owls and migratory birds that may reside on the Project Site through compliance with the requirements of the MBTA. With the incorporation of the PDFs, impacts to biological resources on the Project Site would be reduced to less than significant. Biological resource impacts associated with the 2025 Project would be similar to impacts identified in the Previous Assessments and would be less than significant with the implementation of mitigation measures and project design features. No new information, changed circumstances, or more severe impacts would occur with the implementation of the 2025 Project.

3.8 ENERGY AND MINERAL RESOURCES
3.8.1 Thresholds
a. Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state?
b. Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan?
3.8.2 Summary of Findings in Previous Assessments
As identified in the Previous Assessments, the uses proposed were determined to be consistent with the City’s General Plan. As all development analyzed in the Previous Assessments would conform to standard energy efficient building codes, no significant impacts to energy consumption would occur.
Non-renewable resources, such as natural gas, petroleum products, petrochemical construction materials, steel, copper and other metals, sand and gravel are considered to be commodities which are available in a finite supply. If not consumed by the Project, these non-renewable resources would likely be committed to other projects in the region intended to meet the anticipated growth outlined in the General Plan. Furthermore, the investment of resources in the development of the Specific Plan would be typical of the level of investment normally required for a project of similar scale.
The Previous Assessments identified that the Project Site is located within a MRZ (Mineral Resource Zone)-1, which is defined as areas where adequate information indicates that no significant mineral deposits are present, or where it is judged that little likelihood exists for their presence.23 Most of the developable areas in the City are located in areas with a minimal presence of significant mineral deposits, and no impacts to mineral resources were identified in the Previous Assessments.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to energy or mineral resources. All impacts remained less than significant.
3.8.3 Existing Conditions
The City’s Municipal Code requires that all utilities in new residential districts and subdivisions be undergrounded.24 All new construction of residential and non-residential buildings in the City is required to abide by the Energy Efficiency Standards implemented through California Building Code (CBC) Title 24 in place at the time construction occurs. 23 City of La Quinta, 2035 La Quinta General Plan.

The Project Site is located within the MRZ (Mineral Resource Zone)-1, which is defined as areas where adequate information indicates that no significant mineral deposits are present, or where it is judged that little likelihood exists for their presence.25
3.8.4 Analysis of Proposed Project
The 2025 Project would use less energy than analyzed in the Previous Assessments due to the reduction in intensity of land uses compared to the Previous Assessments. The 2025 Project would comply with the Energy Efficiency Standards set forth in the CBC, including the installation of solar panels on residential units, currently in effect. Energy efficiency standards for development have increased since the Previous Assessments and the 2025 Project would incorporate the latest CBC standards.
The Project Site is designated MRZ-1; therefore, implementation of the 2025 Project would not result in the loss of availability of a locally-important mineral resource considered valuable in the region and state.
Energy and mineral resource impacts associated with the 2025 Project would be similar to impacts identified in the Previous Assessments and would be less than significant. No new information, changed circumstances, or more severe impacts would occur with the implementation of the 2025 Project.

3.9 HAZARDS AND HAZARDOUS MATERIALS
3.9.1 Thresholds
a. Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials?
b. Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?
c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d. Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code, Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
e. For a project located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project site? f. For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project site? g. Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
h. Expose people or structures to a significant risk of loss, injury, or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands?
3.9.2 Summary of Findings in Previous Assessments
The Project Site previously contained an abandoned single-family residence and related agricultural buildings. As part of the 2002 MND, a Phase I Environmental Site Assessment (ESA) was prepared and determined that asbestos was present in some of the building materials of the abandoned single-family residence. The abandoned single-family residence and related agricultural buildings were then demolished, and the Ahmanson House was renovated with the implementation of MM HAZ-1, which ensured the safe removal of asbestos from the Project Site according to applicable regulations.
The Phase I ESA also indicated a potential hazard related to the presence of residual pesticides and herbicides related to previous agricultural uses of the site. Recommendations included mixing upper surface soils to reduce the concentration of residual pesticides and herbicides. Onsite soils were mixed to reduce these concentrations.
Previous Assessments found that the Project Site was located approximately one (1) mile from two underground storage tanks (UST), one at the Oak Tree West property and the other at the Landmark Lease site. The Oak Tree West property was included on the leaking underground storage tank (LUST) list and the Landmark Lease site was included on the historical UST list. The Oak Tree West site was remediated and is listed as a closed case. The Landmark Lease site had no reported violations, as 76 CLICK HERE to Return to Agenda

the underground tanks were removed and closed by the appropriate regulatory agency and no further study or investigation was warranted.
The development of the Project Site with the planned golf course and resort uses was not determined to pose a substantial risk of the release of hazardous materials. Further, Previous Assessments identified that the planned uses would not pose any health hazard or potential health hazard to visitors and nearby residences.
Previous Assessments identified that the Project Site is not within the vicinity of a public use airport or a private airstrip. The nearest public use airport is the Bermuda Dunes Airport, located approximately seven (7) miles north of the Project Site. Jacqueline Cochran Regional Airport, a County-owned public use airport, is located approximately 10 miles east from the Project Site.
The City contracts with Riverside County Fire Department (RCFD) for emergency services, and the City’s Emergency Services Division is responsible for preparing the community for disasters and emergencies. The 2035 General Plan will facilitate new development and consequently increase population within the City. Any increase in population has the potential to impact emergency response and evacuation plans. Previous Assessments concluded that development of the Project Site would not induce population growth.
Previous Assessments found that development of the Project Site would not interfere with any adopted emergency response or evacuation plan since development of the Project Site would not obstruct the existing or planned circulation network. The Project Site is within a low wildfire risk zone and as such, wildland fire impacts would be less than significant.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to hazardous and hazardous materials. All impacts remained less than significant.
Previously Identified Mitigation Measures

Plan (HWMP), which addresses the proper disposal, processing, handling, storage, and treatment of hazardous materials.27
The City’s Emergency Services Division is responsible for responses to disasters and emergencies.
The City has prepared the Emergency Operations Plan to plan and prepare for emergencies. The City established Code Red, which is an ultra-high-speed telephone communication service that provides emergency notifications to residents during emergencies. The City is also involved in the Community Emergency Response Team (CERT) program, which educates volunteers in the community about disaster preparedness and trains them in basic disaster response skills. The CERT group is organized to support the City during emergencies or disasters.
The California Department of Transportation (Caltrans), California Highway Patrol (CHP), and the US Department of Transportation regulate hazardous materials, and the cleanup and containment of accidents. Emergency evacuation and response plans, such as Code Red, are already developed in the City to provide automated notifications to residents during an emergency, including hazardous waste spills.28
The City is located at the base of the Santa Rosa Mountains; however, these areas are considered low wildfire zones as are the flat urbanized areas of the City. The Project Site is not on land classified as a Fire Hazard Severity Zone.29 The Project Site is not located within a site that is included on a list of hazardous materials sites compiled pursuant to Government Code, Section 65962.5 (Cortese List).
3.9.4 Analysis of Proposed Project
As discussed above, the Project Site no longer has hazards associated with it after the implementation of MM HAZ-1. The Project Site has been mass graded and contains the Arnold Palmer Golf Course, Ahmanson House, and partially developed hotel and residential buildings from previous approvals.
The uses included in the 2025 Project are similar to the surrounding land uses in proximity to the Project Site, which consists of other golf and residential communities. The 2025 Project could involve the temporary use of hazardous substances in the form of paint, adhesives, surface coatings and other finishing materials and cleaning agents, fuels, and oils typically used in construction. The transport, use and disposal of construction related hazardous materials would occur in conformance with all applicable local, State, and federal regulations governing such entities. Similar to the planned uses analyzed in Previous Assessments, the 2025 Project’s proposed uses would not pose a substantial risk of release of hazardous materials, and planned uses would not pose any 27 City of La Quinta. 2035 La Quinta General Plan EIR.

health hazard or potential health hazard to visitors or surrounding uses. The Project Site is not located within a site that is included on the Cortese List.30,31 The Project Site is not within one-quarter mile of an existing or proposed school. The nearest school is Harry S Truman Elementary School, located at 78870 Avenue 50, approximately 0.9 miles north of the Project Site.
The Project Site is not within the vicinity of a public use airport or a private airstrip. The nearest public use airport is the Bermuda Dunes Airport, approximately seven (7) miles from the Project Site.
The City contracts with RCFD for emergency services, and the City’s Emergency Services Division is responsible for preparing for disasters and emergencies. As described in detail in Section 3.2 Population and Housing, the 2025 Project would generate a population increase of approximately 1,690 people, which does not represent a substantial increase, as this increase would represent approximately 9.9 percent of the growth projected from 2025 to 2050. The 2025 Project’s proposed residential uses would not induce substantial population growth within the City, and the 2025 Project would reduce the overall residential and hotel uses when compared to the Previous Assessments.
The 2025 Project would not obstruct or interfere with the existing circulation network surrounding the Project Site because the 2025 Project would not alter the existing street system. Additionally, the 2025 Project would have a lower development intensity compared to the land uses analyzed in the Previous Assessments, which would reduce circulation impacts compared to the Previous Assessments. Therefore, the 2025 Project would not interfere with any adopted emergency response or evacuation plans.
The 2025 Project’s proposed uses would not create a fire hazard that has the potential to exacerbate the current environmental condition relative to wildfires. The 2025 Project would be developed in accordance with requirements pertaining to fire safety. The 2025 Project would not expose people or structures, directly or indirectly, to a significant risk of loss, injury, or death as a result of exposure to wildland fires.
Hazards and hazardous materials associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.

For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project site to excessive noise levels?
3.10.2 Summary of Findings in Previous Assessments
The Previous Assessments determined that construction noise would occur throughout development with most of the noise intensive activities occurring at the beginning of development when the site was cleared and graded. Noise intensive activities typically involve the use of heavy equipment, including scrapers, loaders, tractors, and concrete mixers. Trucks would be used during construction to deliver equipment and building materials, as well as haul away waste materials.
Additionally, the Previous Assessments noted that smaller equipment, including jack hammers, saws, pneumatic tools, and hammers, would also be used during construction. This equipment would generate steady state and episodic noise that could be heard on- and off-site, potentially causing construction noise impacts to the surrounding area. The site is surrounded by a residential subdivision and golf course to the north, a residential subdivision and golf course to the east, PGA west golf course and residential community to the south, and the mountains to the west. The noise generated during the construction phase would typically affect the occupants of nearby residences; however, the majority of development would take place at the interior of the site with activities for a planned golf course along the exterior of the site. The Previous Assessments noted that construction activity would be short-term and would not result in significant impacts with the incorporation of MM N-1 through MM N-3, which would restrict construction hours, add mufflers to noise equipment as applicable, and keep earth moving and hauling routes away from existing residences to the extent possible.
The 2035 General Plan projected noise levels on streets adjacent to the Project Site for 2035. The 65 A-weighted decibel Community Noise Equivalent Level (dBA CNEL) noise contour along Jefferson Street between Avenue 52 and Avenue 53 would be 239 feet from the centerline. The CNEL noise level 100 feet from the centerline of Jefferson Street between Avenue 52 and Avenue 54 would be 80 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-45 SilverRock Resort Project Addendum September 2025
70.7 dBA. The 65 dBA CNEL noise contour along Avenue 52 west of Jefferson Street would be 220 feet from the centerline. The CNEL noise level 100 feet from the centerline of Avenue 52 west of Jefferson Street would be 70.1 dBA. The Previous Assessments found that traffic noise impacts would not significantly impact the project. The proposed golf courses planned to be developed on the edges of the Project Site would serve as a buffer from adjacent noise sources. Additionally, the golf course would also attenuate noise levels from the uses proposed in the interior of the Project Site to uses off-site. However, operational noise from the project could potentially impact nearby sensitive receivers such as residences. With the incorporation of MM N-4 and MM N-5, which would strategically place and silence mechanical and outdoor equipment, operational noise impacts related to the project would be less than significant.
The Previous Assessments identified the nearest public use airport as Bermuda Dunes Airport, located approximately seven miles from the Project Site. The Project Site is not located within two miles of a public airport or public use airport and is not located within the vicinity of a private airstrip.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to noise. All impacts remained less than significant with the incorporation of mitigation measures identified in the Previous Assessments.

The primary source of noise in the City and sphere of influence is traffic. The nearest sensitive receptors to the Project Site are the residential uses to the east along Deacon Drive East, to the north along Avenue 52, to the east along Jefferson Street, and to the south along Avenue 54.
Noise standards in the City allow sensitive land uses to experience a maximum noise level of 65 dbA CNEL in outdoor living areas (patios, balconies, and rear yards).
3.10.4 Analysis of Proposed Project
Construction
Noise intensive construction activities would be similar to those previously analyzed. These construction activities typically involve the use of heavy equipment, including scrapers, tractors, loaders, and concrete mixers. Construction of buildings within the Project would involve less heavy equipment, because grading has occurred, but would still generate noise from the use of smaller equipment, including jackhammers, pneumatic tools, saws, and hammers. This equipment would generate both steady state and episodic noise that would be heard both on- and off-site, consistent with the analysis in the Previous Assessments.
Vibration levels due to on-site construction activities would not exceed the building damage significance threshold for vibratory rollers, large bulldozers, caisson drilling, loaded trucks, jackhammers, and small bulldozers at a reference distance of 50 feet or at the nearest sensitive receptors. The nearest sensitive receptors are located over 125 feet away to the west of the Project across Deacon Drive East. Construction would not generate excessive groundborne vibration.
The 2025 Project would comply with the standards set forth by the La Quinta Municipal Code which are identified in MM N-1. Furthermore, the surrounding uses have masonry walls which act as noise barriers which would reduce temporary noise during construction. Construction-related noise impacts would be similar to the impacts identified in the Previous Assessments and with the incorporation of MM N-1 through MM N-3 would be less than significant. Impacts would be less than significant and no new information, changed circumstances, or more severe impacts were identified for the 2025 Project.

Operation
Primary sources of noise throughout the City are caused primarily by motor vehicle traffic on City streets, particularly major roadways.32 Other noise generators in the City include those associated with commercial uses, including mechanical equipment, such as fans, motors, and compressors.
As discussed in Section 3.6: Transportation/Circulation, the proposed Project would reduce the number of daily vehicle trips by approximately 2,800 trips when compared to the 2014 Addendum.
The 2025 Project would have a reduced development intensity compared to the land uses analyzed in the Previous Assessment. However, the vehicles entering and exiting the site would follow similar trip distribution patterns as those identified in the Previous Assessments. Noise levels from vehicles would remain similar, but slightly reduced from noise levels identified in the Previous Assessments.
On-site sensitive uses include the hotel and resort residential units. The distance from the centerline between the golf courses and commercial uses surrounding the edges of the site and the sensitive on-site uses would reduce noise levels below 65 dBA CNEL.
As discussed previously, the City’s Municipal Code establishes base ambient noise level limits for noise sensitive and other non-residential uses based on time of day. The 2025 Project would adhere to the standards set forth by the Municipal Code and incorporate MM N-4 or MM N-5 to reduce operational noise impacts to less than significant levels.
The Project Site is not located within two miles of a public airport or public use airport and would not expose people residing or working in the Project Site to excessive noise levels.
Noise impacts would be similar to impacts identified in the Previous Assessments and would be less than significant with the incorporation of MM N-1 through MM N-5. No new information, changed circumstances, or more severe impacts would occur with the implementation of the proposed Project.

3.11.1 Thresholds
a. Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services:
i) Fire Protection?
ii) Police Protection?
iii) Schools?
iv) Libraries?
3.11.2 Summary of Findings in Previous Assessments
Fire Protection
Previous Assessments analyzed existing fire service and the potential demand for fire service with the development of the project. Development of the project could potentially cause significant fire service demands. Previous Assessments determined that with implementation of MM PUB-1, which requires projects to be reviewed by the Riverside County Fire Department (RCFD) to ensure adequate fire services would be provided at the time of site development, impacts would be reduced to a less than significant level. The project analyzed in Previous Assessments would pay applicable fire protection Development Impact Fees to ensure there is adequate funding of fire protection services.
Police Protection
Previous Assessments analyzed existing police protection services and the potential demand for police protection services with development of the project. Individual development projects are reviewed by the Riverside County Sheriff's Department (RCSD) to ensure adequate police services would be provided at the time of site development. Previous Assessments found that with the implementation of MM PUB-2, which requires the RCSD review new development proposals in order to evaluate the RCSD’s ability to provide adequate police protection, impacts would be reduced to a less than significant level.
Schools
There are two (2) public school districts that serve the City, Desert Sands Unified School District (DSUSD), and the Coachella Valley Unified School District (CVUSD). The Project Site is within the DSUSD service area. Previous Assessments identified that the Proposed Agreements would generate seasonal population growth and would incrementally introduce a small number of seasonal residents similar to those identified in the growth projections from the City’s 2035 General Plan. The proposed development analyzed in Previous Assessments would require payment of applicable school fees. No significant impacts would occur.

Libraries
The La Quinta Library, a city-owned library facility, would serve the Project Site. Previous Assessments identified that the Proposed Agreements would not introduce any permanent residents or result in permanent population growth. There would be a minimal demand for public library services. Any applicable developer fees would have been paid prior to the issuance of building permits.
No new information, changed circumstances, or more severe impacts were identified in Previous Assessments.
Previously Identified Mitigation Measures
MM PUB-1 The Riverside County Fire Department, in its review of new development proposals, shall evaluate project plans and the Department’s ability to provide proper fire protection. This review shall include, but shall not be limited to, internal circulation, project directories, street names, and numbering systems. New developments shall comply with all City and Fire Department standards.
MM PUB-2 The Riverside County Sheriff’s Department shall review new development proposals in order to evaluate project plans and the Department’s ability to provide adequate police protection. This review should include, but not be limited to internal circulation, project directories, street names, and numbering systems. New developments shall comply with all established City and Sheriff standards.
3.11.3 Existing Conditions
Fire Protection
Fire protection for the City is provided through a contract with the RCFD. The two closest City-owned fire stations located within the City are staffed with both full-time paid and volunteer firefighters. Fire Station Number 32 is located at 78-111 Avenue 52, approximately 0.7 miles west of the Project Site and is equipped with both primary and reserve fire engines, along with volunteer squad and rescue vehicles. Fire Station Number 70 is located at 54001 Madison Street, approximately 0.9 miles southeast of the Project Site and is equipped with a primary engine, a brush fire engine, and a volunteer squad vehicle. Currently, average RCFD response times are within the acceptable County standard and align with the National Fire Protection Association (NFPA) guidelines, between 5 and 7 minutes.33

Police Protection
The City contracts with the RCSD for police staffing. As detailed in the 2035 General Plan, the City contract provided for 51 sworn officers and 5 community service officers. The RCSD operates an office within City Hall. A regional station is located in Thermal, which acts as the department’s central facility. The La Quinta Police Department is located approximately 0.5 miles northwest of the Project Site.
The RCSD maintains a staffing level of one staff per 1,000 population; however, the City does not maintain a staffing ratio and staffing is based on the safety needs of the community and the available resources to provide for safety needs. As of January 1, 2025, DOF estimates that the City has a population of approximately 38,796 residents, which would place the level of police staffing at 1.31 staff per 1,000 population.34,35
Schools
The Project Site is within the DSUSD service area.
Libraries
The La Quinta Library, a city-owned library facility, is located at 78-275 Calle Tampico and operated by the County. The La Quinta Library is approximately 0.6 miles northwest of the Project Site.
3.11.4 Analysis of Proposed Project
Fire Protection
The 2025 Project includes the development of a golf course, hotel, residences, and commercial land uses that increase the fire protection services compared to existing conditions. However, development of the 2025 Project would have a lower development intensity compared to the land uses analyzed in the Previous Assessments. The 2025 Project would implement MM PUB-1, which would ensure that the 2025 Project adheres to all RCFD’s regulations for proper fire protection.
Additionally, the 2025 Project would pay the fire protection Development Impact Fee as applicable at the time building permits are issued. Therefore, fire protection impacts associated with the development of the 2025 Project would be similar to those previously analyzed, and less than significant with mitigation.
Police Protection
As was the case in Previous Assessments, individual development projects are reviewed by the RCSD to ensure that adequate police services would be provided to the 2025 Project at the time of 34 Staffing and service ratios for the RCSD were sourced from the City of La Quinta's 2035 General Plan, which provides the most recent available information.

development. As described in Previous Assessments, the implementation of MM PUB-2 would ensure impacts to police protection would be less than significant. The 2025 Project would pay applicable development fees that fund the expansion of essential public facilities such as police protection. Therefore, police protection impacts associated with the development of the 2025 Project would be less than significant with mitigation.
Schools
As mentioned above, the DSUSD district provides school services to the Project Site. The 2025 Project includes approximately 599 hotel/residential units. As described in Section 3.2: Population and Housing, the 2025 Project’s proposed 599 units would generate a population increase of 1,690 people. However, the addition of 1,690 people would not represent a substantial increase, as the 2025 Project’s increase in population would represent approximately 9.9 percent of the growth between 2025 to 2050.
Table 3.11-1: School District Generation Rates and Student Generation shows the projected number of students that would be generated by the 2025 Project. These projections are based on elementary, middle and high school student generation rates used by DSUSD. Student generation rates were derived from the DSUSD’s Fee Justification Study.36 As indicated in the table, the 2025 Project would generate an estimated total of 216 new students, consisting of 92 new elementary school students, 52 middle school students, and 72 high school students. It is possible that residents and students would relocate from elsewhere in the DSUSD service area; however, as a conservative measure, this analysis assumes all new students within this school district. 36 Desert Sands Unified School District (DSUSD). “Fee Justification Study for New Residential and Commercial/Industrial Development.” 2020.

As described in the Previous Assessments, the 2025 Project would comply with the State-mandated school impact fees under SB 50, which are deemed to be full and complete mitigation of the impacts of new development on schools. School impact fees would ensure that impacts of the 2025 Project would be less than significant.
Libraries
The Project Site would be served by the La Quinta Public Library. According to the American Library Association (ALA), the minimum standard for public library space was 1.0 square feet per resident in the library’s service area.38 As of January 1, 2025, DOF estimates that the City has a population of approximately 38,796 residents.39 The La Quinta Library has approximately 20,000 square feet of 37 The Fee Justification Study provides 2019 to 2020 data on student capacity and enrollment. 38 Brawner, Lee B., Donald L., Jr.” Determining Your Public Library’s Future Size: A Needs Assessment and Planning Model.” Institute of Education Sciences. 1996.

library space. Accordingly, the City is below the ALA standard of 1.0 square feet per resident, as the City has approximately 0.52 square feet per resident.
As discussed above, the 2025 Project would generate a population increase of 1,690 people. Using the ALA standard of 1.0 square feet per resident and considering the 2025 Project’s estimated addition of approximately 1,690 people, the ratio of library square feet per resident would be approximately 0.49 feet per resident. The 2025 Project would pay all applicable development fees that fund the expansion of libraries. Therefore, impacts would be less than significant.
Public services impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant through the payment of applicable fees and with the incorporation of MM PUB-1 through MM PUB-2. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.

g. Comply with federal, State, and local statutes and regulations related to solid waste?
3.12.2 Summary of Findings in Previous Assessments
Energy
Electric services are provided to the City from Imperial Irrigation District (IID) and natural gas services are provided to the City from Southern California Gas Company (SoCal Gas). As identified in the City’s General Plan, the IID and SoCal Gas would provide electrical and natural gas services to the Project Site. Additionally, incorporation of MM UTIL-1 and MM UTIL-2 would improve energy efficiency and further minimize the project’s energy demand, resulting in less than significant impacts.
Wastewater Services
CVWD provides wastewater treatment to the City. In the 2002 MND, there were septic tanks within the Project Site. Development of the project could lead to a significant impact on septic tanks. MM UTIL-7 was implemented to remove all septic tanks on the site in accordance with Federal, State and local regulations.
In 2005, the City entered into a Domestic Water and Sanitation System Installation and Irrigation Service Agreement (Water Agreement) with the CVWD for the Specific Plan Area. This Water Agreement required that several local improvements be made to the water delivery system to provide service to the Specific Plan Area. Sewer improvements proposed as part of the project included construction of a 12 inch sewer main in SilverRock Way from the existing Ahmanson House to Avenue 54, a 27 inch sewer main to run west in SilverRock Way to Jefferson Street in the Jefferson Street Access Road, and a 27 inch sewer main to connect to the 12 inch sewer main in SilverRock Way to 90 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-55 SilverRock Resort Project Addendum September 2025
an existing pump station MM UTIL-3 and MM UTIL-6 were implemented to connect the site to the City’s sewer system according to the Water Agreement and pay the developer fees associated with the development of sewer infrastructure.
Sewage generated from the project would be conveyed for treatment to the Mid-Valley Water Reclamation Plant. There were no plans for expansion at the Mid-Valley Water Reclamation Plant, as its capacity was approximately 10 million gallons per day (mgd) and an average of approximately 5 mgd per day was being processed. Therefore, impacts to wastewater service were determined to be less than significant with mitigation incorporated.
Storm Drain Infrastructure
CVWD is the regional authority responsible for the management of drainage within the Coachella Valley, while the City is responsible for storm water management within the City boundaries. The City has prepared a storm water management plan used to direct future management plans and policies.
The Previous Assessments determined that the existing and proposed golf courses within the Specific Plan Area had sufficient capacity to accommodate drainage without any off-site drainage impacts. With implementation of MM UTIL-3 and adherence to the Water Agreement impacts were determined to be less than significant
Water Services
Domestic water is provided to the City by CVWD. The primary source of water is groundwater, which is extracted from the Whitewater River Subbasin by means of a deep well system in the region and imported water from the Colorado River vis the Coachella Canal.
The Water Agreement required improvements to be made as part of the Specific Plan including an 18 inch water main in SilverRock Way from the Ahmanson House to Avenue 54, an 18 inch water main to run west from SilverRock Way to Jefferson Street in the Jefferson Street Access Road, two water well sites, and a pressure reducing/boosting station. All utility infrastructure improvement designs would comply with established CVWD standards and would be subject to CVWD review and approval. With the implementation of MM UTIL-3 and MM UTIL-6, impacts would be less than significant with regards to water service.
A WSA and Water Supply Verification (WSV) was prepared and approved for the project by CVWD that determined CVWD would be able to serve and meet the project water demand of approximately 2,361 acre-feet per year (afy), resulting in less than significant impacts.
Solid Waste
Previous Assessments identified that all solid waste within the Specific Plan Area would be taken to the Edom Hill Transfer Station and transported to either the Lamb Canyon Landfill, Badlands Landfill, or the El Sobrante Landfill. Previous Assessments stated the annual disposal rate at the Lamb 91 CLICK HERE to Return to Agenda

Canyon facility is 0. 46 million tons per year. The landfill is permitted to receive a maximum of 5, 000 tons per day and it is projected that current landfill capacity will extend to 2021, but the Lamb Canyon landfill has potential for expansion. The Lamb Canyon Landfill, Badlands Landfill and El Sobrante Landfill have capacity for the solid waste generated by the project analyzed in the Previous Assessments.
Previous Assessments noted that solid waste generated by construction and demolition sites may account for as much as 22 percent of the solid waste stream. Prior to the issuance of grading permits, the Previous Assessments required recycling of at least 50 percent of these materials, as required by MM UTIL-4. Previous Assessments also identified MM UTIL-5, which would reduce solid waste impacts through professional landscaping services who compost green waste. The proposed development analyzed in Previous Assessments would comply with federal, State, and local statutes and regulations related to solid waste, resulting in less than significant impacts.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to utilities and service systems. All impacts remained less than significant with incorporation of MM UTIL-1 and MM UTIL-7.
Previously Identified Mitigation Measures
MM UTIL-1 The most efficient furnaces, water heaters, pool heaters and other equipment that use natural gas shall be used in project construction. The use of kitchen appliances that use natural gas and alternative, renewable energy sources, including solar and wind turbine technologies, shall also be used to the greatest extent feasible.
MM UTIL-2 Title 24 of the California Administrative Code, which addresses energy conservation in all proposed uses, shall be strictly enforced in project design and construction.
MM UTIL-3 All planned uses shall be connected to the city-wide sewer system.
MM UTIL-4 A recycling program shall be developed for all proposed uses. Recycling provisions for commercial and business establishments should include separate recycling bins. Items to be recycled at commercial establishments may include white paper, computer legal paper, cardboard, and glass and aluminum cans.
MM UTIL-5 Professional landscaping services from companies which compost green waste shall be utilized.

MM UTIL-7 Any existing or historic septic systems located on the site shall be abandoned in accordance with federal, state, and local laws and regulations prior to the issuance of building permits.
3.12.3 Existing Conditions
Energy
Electric services are provided to the City from IID and natural gas services are provided to the City of SoCal Gas.
Wastewater Services
The CVWD is responsible for wastewater treatment in the City of La Quinta. The CVWD maintains a network of sewer trunk lines throughout the City ranging in size from 4 to 24 inches in diameter. An 18- inch main line is located adjacent to the Project Site in the Jefferson Street right-of-way. The MidValley Reclamation Plant would treat wastewater generated from the Project Site.
Storm Drain Infrastructure
As discussed in Previous Assessments, existing and proposed golf courses within the Specific Plan Area have sufficient capacity to accommodate drainage without any off-site drainage impacts.
The storm drain within Avenue 52 is designed to convey stormwater into the envelope of the proposed second golf course along Avenue 52 and Jefferson Street (Planning Area 8) to allow for percolation into the groundwater aquifer. The 2025 Project would incorporate similar amounts of open space as identified in the Specific Plan to allow for percolation of water runoff into the aquifer.
Water Services
The Project Site is within the CVWD service area. CVWD’s total water production reached 99,843 acre-feet per year (AFY) in 2020.40 CVWD’s domestic water system has 64 pressure zones. This consists of approximately 97 groundwater production wells, 2,000 miles of pipe, and 133 million gallons of storage in 65 enclosed reservoirs.41 The primary water supply for CVWD is groundwater from the Whitewater River Subbasin in the Coachella Valley and it supplements groundwater use with imported water and use of reclaimed water.

Approximately 19 acres of the Coachella Canal,42 are located within the boundaries of the Project Site. Up to 97 percent of the 2025 Project's water usage for irrigation purposes, which is by far the majority of the total water demand for the 2025 Project, may be obtained from the Coachella Canal in accordance with the terms of the existing Water Agreement between the City and CVWD.
Indirectly, canal water will be used for groundwater recharge and source substitution throughout the Coachella Valley. Water to the Specific Plan Area is provided by CVWD through the existing 18-inch water main beneath SilverRock Way.
Solid Waste
The City has a franchise agreement with Burrtec Waste and Recycling Services, LLC (Burrtec) for the provision of solid waste disposal within the City and the City’s Sphere of Influence. Non-hazardous household, commercial and most non-hazardous industrial solid waste collected in the City is taken to the Edom Hill Transfer Station in Cathedral City. From there, waste is transported to one of three landfills: the Lamb Canyon regional landfill; El Sobrante Landfill; or the Badlands Landfill. The Project Site would be served by Burrtec.
3.12.4 Analysis of Proposed Project
Energy
As detailed above, the City’s General Plan identified that IID and SoCal Gas would provide electrical service to the Project Site. Incorporation of MM UTIL-1 and MM UTIL-2 would improve energy efficiency and further minimize the project’s energy demand. Further, the 2025 Project would reduce development intensity compared to the land uses analyzed in the Previous Assessments. Therefore, impacts would be less than significant with mitigation incorporated.
Wastewater Services
As discussed above, the Project Site is connected to the City’s sewage system. These sewer lines would adequately serve the project as analyzed in the Previous Assessments. The 2025 Project would reduce overall development intensity, which would reduce wastewater generation. Therefore, sewage impacts would be less than significant.
Storm Drain Infrastructure
Storm drains to adequately serve the project analyzed in Previous Assessments have been constructed. The existing Project Site, including the existing and proposed golf courses within the Specific Plan Area have sufficient capacity to accommodate on-site drainage without off-site drainage impacts. The 2025 Project would incorporate similar amounts of open space for the golf 42 Note: The Coachella Canal is a branch of the All-American Canal that brings Colorado River water into the Imperial and Coachella Valleys.

course as identified in Previous Assessments, to allow for percolation of water runoff into the aquifer.
As a result, the 2025 Project would not require or result in the construction of new storm water drainage facilities or expansion of existing facilities. The 2025 Project would reduce overall development intensity compared to that analyzed in the Previous Assessments, which would reduce demand on storm drain infrastructure. Therefore, impacts would be less than significant.
Water Services
As described above, domestic water is provided in the City by CVWD. A WSA and WSV were developed for the project analyzed in the Previous Assessments, which confirmed that CVWD would have the current and future water supply necessary to provide water for the Specific Plan and other existing and planned future uses that would be served by the CVWD. The 2020 Coachella Valley Regional Urban Water Management Plan confirms that CVWD has adequate water supplies to 2045 under normal, single and multiple dry years.43 As previously described, a majority of the 2025 Project’s water usage is for irrigation purposes, which may be obtained from the Coachella Canal, in accordance with the terms of the existing Water Agreement between the City and the CVWD. Further, the 2025 Project would reduce overall development intensity compared to the project analyzed in the Previous Assessments, which would reduce water demand. The water demand estimate for the SilverRock Resort Project in the 2006 Water Supply Assessment (WSA) approved for the project was approximately 2,361 acre-feet per year. The estimated water demand for the 2025 Project is approximately 2,376 acre-feet per year.44 This potable water demand is less than one percent greater than the demand estimate in the approved WSA. This incremental increase does not represent a substantial increase in water demand for the project. The 2025 Project would not require water service improvements, as previously proposed water infrastructure improvements as part of the Specific Plan were already completed, including the 18-inch water main beneath SilverRock Way.
Impacts to water supplies and services would be less than significant.
Solid Waste
The City and Project Site are serviced by Burrtec. Solid waste generated in the Project Site would be taken to the Edom Hill Transfer Station and then transported to either the Lamb Canyon Landfill, Badlands Landfill, or the El Sobrante Landfill.

facility is approximately 50 million tons per year.45 The landfill is permitted to receive a maximum of 5,000 tons per day and is projected that the current landfill capacity will extend to 2029.46 The Previous Assessments determined that with the implementation of MM UTIL-4 and MM UTIL-5, which sets forth a recycling program for all proposed uses, and utilizes professional landscaping services to compost green waste, impacts would be less than significant. The 2025 Project would continue to implement those mitigation measures. Additionally, the 2025 Project would reduce development intensity compared to the project analyzed in the Previous Assessments, resulting in less solid waste generation. Therefore, the 2025 Project would be adequately served by solid waste services.
The 2025 Project would comply with federal, State and local statues and regulations related to solid waste, such as AB 341, SB 1016, Per Capita Disposal Rate and AB 939. Impacts to solid waste would be less than significant with mitigation incorporated.
Utilities and service systems impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant through the incorporation of MM UTIL-1, MM UTIL-2, MM UTIL-4, and MM UTIL-5. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.

3.13 AESTHETICS
3.13.1 Thresholds
a. Have a substantial adverse effect on a scenic vista? b. Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?
c. Substantially degrade the existing visual character or quality of the site and its surroundings?
d. Create a new source of substantial light or glare, which would adversely affect day or nighttime views in the area?
3.13.2 Summary of Findings in Previous Assessments
The Specific Plan contains design standards related to building heights, setbacks, scale and architectural treatments that require developments adjacent to the Santa Rosa and San Jacinto Mountains to maintain views from adjacent locations off-site. The Specific Plan has a range of maximum building heights that range from 28 to 60 feet tall and maximum stories ranging from two to five stories tall. Previous Assessments identified that the development of the Project Site would include 2- to 3-story buildings that would allow views of the Santa Rosa and San Jacinto Mountains from the adjacent buildings and the public rights-of-way. The planned development analyzed in Previous Assessments would go through the site plan review process to ensure enforcement of the City’s development standards. Previous Assessments found that the planned development would not obstruct views of the mountains and would result in less than significant impacts.
The 2035 General Plan identified Jefferson Street and Avenue 52 as image corridors. As roadways with these classifications are required to be improved and maintained with appropriate setbacks, landscaping materials and signage according to the Specific Plan, the planned development analyzed in Previous Assessments would provide landscaping and parkway treatments consistent with surrounding uses. This would be reviewed and enforced during site plan review. Previous Assessments identified that potential aesthetic impacts along Jefferson Street and Avenue 52 would be mitigated to less than significant levels through the implementation of MM AES-4, MM AES-6, and MM AES-7. MM AES-4 would limit signage sizing based on location, size and maintenance; MM AES6 would ensure proposed development along scenic highways, roadways and corridors is reviewed for compatibility with the natural and built environments; and MM AES-7 would regulate all grading and development within scenic viewsheds to assure maximum viewshed protection and pedestrian and vehicular activity.
There are no officially designated state scenic highways within the City, and the planned development in Previous Assessments would not substantially damage scenic resources within a state scenic highway. The Project Site does not contain scenic resources, including trees, rock outcroppings, or historic buildings. The Ahmanson House, built after 1950, is located within the Project Site. However, in Previous Assessments the Ahmanson House was not identified as a historic 97 CLICK HERE to Return to Agenda

landmark. Previous Assessments found that the development of the Project Site would not substantially damage scenic resources within a state scenic highway and impacts to scenic resources along a state scenic highway would be less than significant.
Previous Assessments identified that development of the Project Site would develop vacant portions of the Project Site and would improve the visual character of the undeveloped land with resort uses.
The development analyzed in Previous Assessments would be compatible with the Project Site’s surrounding uses and the visual character of the City, including golf communities. Previous Assessments incorporated MM AES-1, MM AES-2, and AES-5 to further minimize visual character impacts, resulting in less than significant impacts. MM AES-1 regulates landscape designs and materials, would ensure that project design would complement the native desert environment; MM AES-2 ensures that overhead utility lines would be undergrounded, subject to the review of the City Engineer and Public Works Department; and MM AES-5, requires safe circulation, screened areas, protected and enhanced outdoor seating areas, appropriate lighting levels, limited signage and landscaping designs.
Previous Assessments found that development of the Project Site would comply with the City’s Dark Sky Ordinance with implementation of MM AES-3. MM AES-3 states that any proposed lighting on a building or parking lot shall be shielded so that light is projected downward and not onto adjacent properties or the public right-of-way.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to aesthetics. All impacts remained less than significant with the incorporation of MM AES-1 through MM AES-7.
Previously Identified Mitigation Measures
MM AES-1 Landscape designs and materials that complement the native desert environment shall be utilized in project design and construction.
MM AES-2 Overhead utility lines shall be undergrounded to the greatest extent possible through the establishment of an undergrounding program and guidelines subject to the review of the City Engineer and Public Works Department MM AES-3 Outdoor lighting shall be limited to the minimum height, number of fixtures, and intensity needed to provide sufficient security and identification in each development, making every reasonable effort to protect the community’s night skies, consistent with the City Dark Sky Ordinance.
MM AES-4 Signage shall be limited to the locations, sizes, and maintenance requirements necessary to provide functional identification.
MM AES-5 Safe, convenient vehicular and pedestrian circulation, screened outdoor storage/loading and other unsightly areas, protected and enhanced outdoor seating 98 CLICK HERE to Return to Agenda

areas, appropriate lighting levels, limited signage, and landscaping designs that preserve and enhance visual resources shall be included in the design of any commercial area on the Project Site.
MM AES-6 Development proposed along designated scenic highways, roadways and corridors shall be reviewed for compatibility with the natural and built environments to assure maximum viewshed protection and pedestrian and vehicular activity.
MM AES-7 All grading and development proposed within scenic viewsheds shall be regulated to minimize adverse impacts to these viewsheds. All grading, development, and landscaping plans shall be submitted to the City for review and approval prior to the issuance of grading permits.
3.13.3 Existing Conditions
According to the City’s General Plan EIR, the existing visual character of the City is characterized as suburban, with residential neighborhoods, commercial shopping centers, office parks, golf courses, parks, and community facilities.47 Development within the City is generally lower density and buildings are typically low-rise structures. Surrounding uses near the Project Site include golf courses, residential communities and open space areas.
The Project Site has been mass graded and contains the Arnold Palmer Golf Course, Ahmanson House, and partially developed hotel and residential buildings from previous approvals. Scenic vistas surrounding the Project Site include views of natural features, such as the Santa Rosa Mountains.
The Project Site is adjacent to the Santa Rosa and San Jacinto Mountains, which are identified as visual resources in the City’s 2035 General Plan.
There are no state scenic highways within the City.48 The Project Site is adjacent to two (2) image corridors, Jefferson Street and Avenue 52.
Existing sources of light and glare near the Project Site are located along major arterials, such as Jefferson Street, produce light and glare from signalized intersections, street lamps, and vehicle headlights. Additionally, light from surrounding developments contribute to the ambient lighting of the Project area. Lighting within the Project Site includes lighting from the golf course and clubhouse for the purpose of nighttime visibility, safety, security and operation.
3.13.4 Analysis of Proposed Project
As discussed above, the Project Site is completely graded and partially developed. There are no existing scenic resources on the Project Site. Scenic vistas and resources near the Project Site 47 City of La Quinta, Environmental Impact Report for the City of La Quinta General Plan (2013). 48 Caltrans. “California State Scenic Highways.” Accessed July 2025. https://caltrans.maps.arcgis.com/apps/webappviewer/index.html?id=465dfd3d807c46cc8e8057116f1aacaa. 99 CLICK HERE to Return to Agenda

include the Santa Rosa and San Jacinto Mountains. The Project Site would adhere to design standards set forth in the Specific Plan, which require developments adjacent to the mountains to maintain views from adjacent locations off-site. These design standards regulate building height, setbacks, scale, and architectural treatments. The 2025 Project would allow the development of buildings with a maximum height of 60 feet, which would adhere to the Specific Plan design regulations and allow views of the Santa Rosa and San Jacinto Mountains from the adjacent buildings and the public rights-of-way. Review of the site plan for the 2025 Project would ensure compliance with the City’s development standards. Accordingly, the 2025 Project would not obstruct views of nearby scenic resources and vistas.
Jefferson Street and Avenue 52 are adjacent to the Project Site, which are both identified as image corridors in the 2035 General Plan. Development of the 2025 Project would adhere to roadway improvement requirements, which include appropriate setbacks, landscaping materials, and signage. The 2025 Project would provide landscaping and parkways consistent with surrounding uses. Site plan review of the 2025 Project would further ensure improvements are consistent with surrounding uses.
There are no officially designated state scenic highways within the City. Therefore, the 2025 Project would not substantially damage scenic resources within a state scenic highway.
In 2017, the City recorded a property covenant49 that recognizes the Ahmanson Ranch House as a historic resource and limits alterations to the building. This covenant requires the Ahmanson Ranch House property to be preserved as an historic resource, unless modifications are approved by the City Council under its regulatory and design review authority, in accordance with all applicable laws.
Under the proposed Reinstated and Amended Development Agreement, the Ahmanson Ranch House Property remains subject to these same protections. Any future proposal to modify the Ahmanson Ranch House would be subject to City Council review and all applicable requirements of CEQA.
The City’s 2023 Historic Resource Survey identifies the Ahmanson House as ahistoric resource.50 The existing Ahmanson House property is intended to be repurposed for use as a restaurant or other hotel amenity, consistent with the existing covenant. No significant aesthetic impacts would occur.
The 2025 Project would develop resort uses and a second golf course that would improve the visual character of the largely undeveloped Project Site. Surrounding uses near the Project Site include golf courses, residential communities and open space areas. The 2025 Project would be compatible with the site’s surrounding uses and visual character of the City.

the 2025 Project would adhere to MM AES-1, MM AES-2, MM AES-4, MM AES-5, MM AES-6, and MM AES-7, which would further ensure the 2025 Project is visually compatible with the surrounding land uses and the City’s visual character.
Due to the primarily urbanized nature of the area, a moderate level of ambient nighttime light already exists. Nighttime lighting sources include streetlights, vehicle headlights, and building illumination.
The 2025 Project would add new lighting sources within the Project Site. However, the 2025 Project would comply with the City’s Dark Sky Ordinance and MM AES-3, which states that any proposed lighting on a building or parking lot shall be shielded so that light is projected downward and not onto adjacent properties or the public right-of-way, resulting in less than significant light and glare impacts.
Aesthetics impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant through the incorporation of MM AES-1 through MM AES-7.

3.14 CULTURAL RESOURCES
3.14.1 Thresholds
a. Cause a substantial adverse change in the significance of a historical resource b. Is defined in CEQA Guidelines Section 15064.5?
c. Cause a substantial adverse change in the significance of an archaeological resource pursuant to CEQA Guidelines, Section 15064.5?
d. Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
e. Disturb any human remains, including those interred outside of formal cemeteries?
3.14.2 Summary of Findings in Previous Assessments
The Project Site was originally undeveloped except for the abandoned single-family resident house and the Ahmanson House, the house belonging to the philanthropic Ahmanson family. A cultural study was conducted for the previous project and determined that none of the structures on the site had historic landmark status, nor were there any known cultural resources on the site. Since the initial 2002 MND, the Specific Plan Area has been mass graded and developed with the Arnold Palmer Golf Course; no paleontological resources, archeological resources or human remains were found during this time. However, as part of the 2035 General Plan Update, a Paleontological Resources Technical Report was completed, which found that the Project Site is in an area designated as having a high palaeontologic sensitivity. Additionally, the potential for encountering archeological and paleontological resources during development of the site was identified. Previous Assessments identified MM CUL-1, which requires the retainment of a qualified archaeological and paleontological monitor in order to reduce potential impacts to archaeological and paleontological resources to a less than significant level.
Previous Assessments stated that if human remains were discovered during ground-disturbing activities, all such activities within a 100-foot radius of the find would be halted immediately and the designated representatives would be notified. All development activities would be conducted in accordance with applicable regulations related to the discovery of human remains in California Health and Safety Code Sections 7050. 5 and 7052 and California Public Resources Code Section 5097.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to cultural resources. All impacts remained less than significant with mitigation incorporated.
Previously Identified Mitigation Measures
MM CUL-1 During any ground altering activities associated with project grading or construction, including demolition of existing modern structures and facilities, the project area shall be monitored by a qualified archaeological monitor and a qualified 102 CLICK HERE to Return to Agenda
3.0—Impact Analysis

paleontological monitor shall be required in the event of discovery of resources. The monitor shall have the authority to halt any activities impacting potentially significant cultural resources until the resources can be evaluated for significant and cleared or mitigated. The monitoring program shall also include consultation with the local Native American representatives (e.g., Torres-Martinez and/or Morongo Reservations) consistent with applicable statutes governing cultural resources.
3.14.3 Existing Conditions
In 2023, the City completed a Historic Resource Survey and Context Statement to evaluate the significance and integrity of historic-era properties within the City under the criteria of the National Register of Historic Places (NRHP), the California Register of Historical Resources (CRHR), and the La Quinta Historic Resources Inventory (Local Register). The survey identified 489 historic-era properties within the City boundaries. 363 sites were documented and evaluated, with 103 of these properties identified as significant and eligible for designation and listing on the Local Register, CRHR, or NRHP, either individually or as contributors to a local historic district. 259 properties were identified as not significant and ineligible for listing on the Local Register, CRHR or NRHP.51 The City’s 2023 Historic Resource Survey identifies the Ahmanson House as eligible for local listing and the National and California Registers.52 The nearest historic resource is approximately 1.5 miles west of the Project Site but is separated from the Project Site by the base of the Santa Rosa Mountains. The Arnold Palmer Classic Golf Course is located on the most western portion of the site alongside the edge of the Santa Rosa Mountains; however, this area has already been disturbed by previous development. The Project Site was previously mass graded, and portions of the Project Site have been disturbed and developed.
3.14.4 Analysis of Proposed Project
In 2017, the City recorded a property covenant53 that recognizes the Ahmanson Ranch House as a historic resource and limits alterations to this building. This covenant requires the Ahmanson Ranch House property to be preserved as a historic resource, unless modifications are approved by the City Council under its regulatory and design review authority, in accordance with all applicable laws.
Under the proposed Reinstated and Amended Development Agreement, the Ahmanson Ranch House Property remains subject to these same protections. Any future proposal to modify the Ahmanson Ranch House would be subject to City Council review and all applicable requirements of CEQA.

House as eligible for local listing or designation and as eligible for the NR and CR individually through survey evaluation.54 No impacts to historic resources were identified for the project. The Project Site was previously mass graded. However, there is potential for the unanticipated discoveries of archeological, paleontological resources and human remains with further development of the site.
The 2025 Project would implement MM CUL-1, which would ensure impacts to archaeological and paleontological resources would remain less than significant. Therefore, impacts would be less than significant with mitigation incorporated.
Although there is little potential for the accidental discovery of human remains at this point in time as the site has been fully graded and partially developed, if human remains were to be discovered during construction, the requirements of the California Health and Safety Code Section 7050.5 would apply, and disposition of the human remains and any associated grave goods would occur in accordance with PRC Section 5097.91 and 5097.98 would be implemented.
Cultural resource impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant with mitigation incorporated. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.

3.15 RECREATION
3.15.1 Thresholds
a. Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated?
b. Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment?
3.15.2 Summary of Findings in Previous Assessments
Previous Assessments identified that the Project Site would include two (2) public golf courses along with additional public park space, which would be considered recreational resources within the City.
Development of the Project Site could generate a small number of residents within the Specific Plan Area, as is typical for homes in resort communities in the Coachella Valley. Previous Assessments identified the Quimby Act fees, or an in-lieu parkland fee, would be paid to the City to offset potential resident use of parkland located outside of the Specific Plan Area. Development of the Project Site would provide additional public recreational services without significantly increasing the City’s population. Previous Assessments found that development of the Project Site would not result in increased demand on neighborhood or regional park facilities, nor would it affect existing recreational opportunities.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to recreation. All impacts remained less than significant.
3.15.3 Existing Conditions
The City owns and operates several park facilities including both active and passive recreational opportunities for residents and visitors. There are four (4) community parks in the City, including the
16.75-acre La Quinta Sports Complex, the 18-acre La Quinta Park (part of Old Town La Quinta), the
17.5-acre Civic Center Campus, and the 14-acre SilverRock Park located in the northwest portion of the SilverRock Specific Plan area. The City's four (4) neighborhood parks include Fritz Burns Park, Adams Park, Monticello Park, and Pioneer Park. The City has five (5) mini parks, including Eisenhower Park, Seasons Park, Saguaro Park, Desert Pride and Velasco Park. The City's Cove Oasis is a 114-acre natural open space area with trails, and the Fred Wolff Nature Preserve is a 20-acre natural open space area. Additionally, the City recently developed a skate park.
There are approximately 5,259 acres of open space areas set aside for recreational facilities within the City. These developed open-space recreational areas include a variety of City owned and maintained parks and facilities, County of Riverside-owned parks, Desert Recreation District facilities, and public and private golf courses. In addition, there are approximately 6,933 acres of 105 CLICK HERE to Return to Agenda
3.0—Impact Analysis

natural open space areas within the City, which include hiking trails, equestrian trails, and other passive recreation opportunities.
3.15.4 Analysis of Proposed Project
As further described in Section 3.2: Population and Housing, the 2025 Project would generate a population of 1,690 people from the proposed 599 hotel/residential units. The Quimby Act, established by state law, requires that every county and city meet the standard of 3 acres of parkland per 1,000 residents.55 The 2025 Project would require 5.07 acres of recreational space in order to adhere to the Quimby Act.56 The City’s 2035 General Plan’s Policy PR 1.2 aims to provide a minimum standard of 5 acres of parkland for every 1,000 residents, which would require 8.45 acres for the 2025 Project.57,58
The recreational amenities in the 2025 Project would include the approximately 173-acre Arnold Palmer Golf Course, the additional 18-hole golf course, a 20,000-SF clubhouse, and other amenities like tennis, pickleball, padel among others, which will well exceed the recreational acres required to adhere to the Quimby Act and Policy PR 1.2. Therefore, the 2025 Project would not be required to pay any Quimby Act fees. The 2025 Project would not result in increased demand on neighborhood or regional park facilities, nor would it affect existing recreational opportunities. Impacts on recreation would be less than significant.
Recreation impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.

3.16 GREENHOUSE GASES
3.16.1 Thresholds
a. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
b. Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
3.16.2 Summary of Findings in Previous Assessments
At the time of the preparation of the 2002 MND and 2006 Addendum, the topic of Greenhouse Gases (GHGs) and the associated checklist questions were not included in the CEQA Guidelines Appendix G Checklist and, therefore, analysis was not required. Greenhouse gas emissions thresholds were added in 2010, and as such, the 2014 Addendum addressed GHG emissions resulting from the 2006 Addendum and the 2014 Addendum.
The 2014 Addendum concluded that development of the Project Site with proposed land uses would not result in the generation of greenhouse gas emissions that would have a significant impact on the environment. Construction activities analyzed in the Previous Assessment were estimated to generate 8,595 metric tons of carbon dioxide equivalents (MTCO2e) GHG emissions. Operational emissions were estimated with the incorporation of the standard project design features (PDFs) identified in the City’s 2035 General Plan. Design features included GHG PDF-1 through GHG PDF-3 focused on efficient landscaping, GHG PDF-4 requiring efficient building design, GHG PDF-5 implementing renewable energy, GHG PDF-6 referring to recycling and composting, and GHG PDF7 through GHG PDF-9 to reduce reliance on traditional automobiles for transportation.
The development of the Project Site was found to be consistent with the targets set forth in the City’s Greenhouse Gas Reduction Plan (GGRP) by achieving 10 percent below 2005 emissions levels by 2020 and 28 percent below 2005 levels by 2035. For this reason, the 2014 Addendum also concluded that development of the Project Site would be consistent with the goals of AB 32 and the GGRP set forth by the City and would not conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases.
No new information or changed circumstances were identified in the Previous Assessments that resulted in new or more severe impacts related to greenhouse gas emissions. All impacts remained less than significant.
Previously Identified Project Design Features
The following design features were identified by the 2014 Addendum:
GHG PDF-1 Landscaping designs shall consider the use of trees and other vegetation to maximize the shading of buildings in order to reduce energy requirements for heating and cooling and provide carbon storage.
107 CLICK HERE to Return to Agenda
3.0—Impact Analysis
Meridian Consultants 3.0-72 SilverRock Resort Project Addendum September 2025
GHG PDF-2 Desert landscaping techniques shall be utilized, including the use of automated water efficient irrigation systems and devices.
GHG PDF-3 Smart scalping practices shall be encouraged to minimize fugitive dust emissions and reduce water demands.
GHG PDF-4 Building designs shall strive to exceed Title 24 requirements or achieve LEED or Energy Star standard equivalence ratings or better; buildings shall be equipped with energy efficient and water conserving appliances and fixtures; building design shall include natural lighting and ventilation; and light colored “cool” roofs and cool pavement shall be utilized.
GHG PDF-5 New buildings and substantial remodels including new roofs, should be designed to accommodate rooftop photovoltaic or above parking solar.
GHG PDF-6 Recycling and composting facilities and programs shall be readily available for all new and existing land uses and every effort shall be made to divert the landfill waste stream.
GHG PDF-7 Promote the use of electric vehicles and alternative modes of transport by providing safe and convenient bicycle, scooter and other non-motorized transport travel lanes, and parking, as well as preferential plug-in stations for electric vehicle parking.
GHG PDF-8 Assure all new development has safe and convenient access to public transit routes that include seated, shaded bus stop areas.
GHG PDF-9 Incorporate recreational open space adjacent to or as part of residential land uses.
3.16.3 Existing Conditions
The California State Legislature enacted Assembly Bill (AB) 32, the California Global Warming Solutions Act of 2006. AB 32 focuses on reducing greenhouse gas (GHG) emissions in California.
GHGs, as defined under AB 32, include carbon dioxide (CO2), methane, NOx, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. AB 32 requires that GHGs emitted in California be reduced to 1990 levels by the year 2020. The California Air Resources Board (CARB) approved a Climate Change Scoping Plan (Scoping Plan) on December 11, 2008, as required by AB 32. The Scoping Plan proposed a “comprehensive set of actions designed to reduce overall carbon GHG emissions in California, improve our environment, reduce our dependence on oil, diversify our energy sources, save energy, create new jobs, and enhance public health.”59 The Scoping Plan had a range of GHG reduction actions, including direct regulations; alternative compliance mechanisms; monetary and nonmonetary incentives; voluntary actions; market-based mechanisms, such as a cap-and-trade system; and an AB 32 implementation regulation to fund the program. 59 California Air Resources Board (CARB).

Meridian Consultants 3.0-73 SilverRock Resort Project Addendum September 2025
The most recent version of the Scoping Plan60 was approved on December 15, 2022, and is the most comprehensive and far-reaching Scoping Plan developed to date. It identifies a technologically feasible, cost-effective, and equity-focused path to achieve new targets for carbon neutrality by 2045 and to reduce anthropogenic GHG emissions to at least 85 percent below 1990 levels, while also assessing the progress California is making toward reducing its GHG emissions by at least 40 percent below 1990 levels by 2030, as called for in SB 32 and laid out in the 2017 Scoping Plan.61 The 2030 target is an interim but important stepping stone along the critical path to the broader goal of deep decarbonization by 2045.
The City adopted a GGRP in order to meet the requirements of AB 32. The GGRP establishes current emissions and sets targets for long-term reductions. The GGRP includes a comprehensive inventory of greenhouse gas emissions generated City-wide, including those generated by local government activities. Future emissions of greenhouse gases are projected, reduction targets set, and policies and programs are proposed as part of the GGRP in order for the City to meet mandated reductions.
To be consistent with AB 32, the reduction target is to achieve 1990 level emissions by 2020, and 80 percent below 1990 levels by 2050.62 Pursuant to AB 32, ARB established statewide 1990 greenhouse gas emissions as 427 million metric tons of carbon dioxide equivalents (MMTCO2e).63 Community-wide activities in the City generated an estimated 1,228,050 metric tons of carbon dioxide equivalents (MTCO2e) in 2005.
3.16.4 Analysis of Proposed Project
Construction and operational emissions were modeled in CalEEMod (Version 2022.1) for the land uses described in the 2014 Addendum and the land uses described in the 2025 Project to provide an accurate comparison of emissions.
Construction
Construction activity impacts are relatively short in duration, so they contribute a relatively small portion of the total lifetime GHG emissions of a project. The combustion of fossil fuels in construction equipment results in GHG emissions of CO2 and smaller amounts of CH4 and N2O.
Emissions of GHG would also result from the combustion of fossil fuels from vendor trucks delivering materials and construction worker vehicles commuting to and from the Project Site.

duty and medium-duty automobiles and trucks would be used for worker trips and heavy-duty trucks would be used for vendor trips. The vast majority of motor vehicles used for worker trips would rely on gasoline as an energy source, while motor vehicles used for vendor trips would primarily rely on diesel as an energy source.
As presented in Table 3.16-1: Construction Greenhouse Gas Emissions, construction activities associated with the 2025 Project would generate 15,397 MTCO2e GHG emissions. The SCAQMD recommends annualizing construction-related GHG emissions over a project’s lifetime, defined as a 30-year period, in order to include these emissions as part of the annual total operational emissions.
Therefore, construction-related GHG emissions have been annualized over this period and included in the annual operational emissions.
As described above, construction activities associated with the 2014 Addendum were modeled in CalEEMod (Version 2022.1) for the land uses described in the 2014 Addendum in order to provide accurate comparison of emissions to the 2025 Project due to updates in the modeling software.
Construction activities associated with the 2025 Project would generate a reduced amount of GHG emissions compared to those estimated in the 2014 Addendum as shown in Table 3.16-1. GHG would be reduced due to the reduction is land use intensity compared to the Previous Assessments.

Operation
Emissions from mobile and area sources and indirect emissions from energy and water use, wastewater, as well as waste management would occur every year after full development of the Project. A summary of the annual operational emissions of both the 2025 Project and the 2014 Addendum Project are provided in Table 3.16-2: Operational GHG Emissions. As described above, operational activities associated with the 2014 Addendum were modeled in CalEEMod (Version 2022.1) for the land uses described in the 2014 Addendum in order to provide an appropriate comparison of emissions to the 2025 Project due to updates in the modeling software. The operation estimates represent emissions with incorporation of the standard design features identified in the City’s 2035 General Plan during operations.
To provide guidance to local lead agencies on determining significance for GHG emissions in their CEQA documents, SCAQMD staff has proposed a tiered series of thresholds to be applied based on the amount of GHG emissions generated by a proposed project and the type of project. The first tier does not apply to the 2025 Project because the Project is not categorically exempt from CEQA. The second tier threshold of significance is applied if the project is subject to an adopted GHG reduction plan. The City has adopted a GGRP which applies to the 2025 Project. The analysis presented below compares the proposed Project’s GHG emission reductions from the 2014 Addendum Project. The 2025 Project’s GHG emission reduction will then be compared to the City’s GGRP reduction targets. 111 CLICK HERE to Return to Agenda

Abbreviations: MTCO2e = metric tons of carbon dioxide emissions. *N2O emissions account for 0.18 and 0.30 MTCO2e/year, respectively.
Community-wide activities in the City generated an estimated 1,228,050 MTCO2e in 2005. As such, the targets set forth in the GGRP are to achieve 10 percent below 2005 emission levels by 2020 and 28 percent below 2005 levels by 2035.64 To reach these targets, the GGRP includes a wide range of implementation tools which can be implemented by City officials, residents, and business owners.
As shown in Table 3.16-2, the operational GHG emissions for the 2025 Project would be 16,789 MTCO2e per year. When modeled in CalEEMod (Version 2022.1) for the land uses evaluated in the 2014 Addendum, the operational GHG emissions for the 2014 Addendum Project would result in 22,644 MTCO2e per year. The 2025 Project would reduce GHG emissions by 5,875 MTCO2e per year, approximately 26 percent, from the 2014 Addendum Project. Therefore, GHG emissions generated by the 2025 Project would be consistent with the targets set forth in the GGRP by achieving 10 percent below 2005 emissions levels by 2020 and 28 percent below 2005 levels by 2035. Impacts would be less than significant.
Conflict with an Applicable Plan, Policy, or Regulation The GGRP sets targets and identifies reduction measures to ensure that the City is consistent with AB 32 goals of reducing GHG emissions by 2020 and 2035. As previously identified, the GGRP identified that the City would need to achieve a 10 percent reduction from 2005 levels by 2020 and 28 percent reduction from 2005 levels by 2035. As indicated in Table 3.16-2, the 2025 Project would result in 16,694 MTCO2e per year. The 2025 Project would reduce GHG emissions by 5,970 MTCO2e per year, approximately 26 percent, compared to the emission estimate for the 2014 Addendum. The 2025 Project would be consistent with the goals of AB 32 and the GGRP set forth by the City for the 64 City of La Quinta. 2035 La Quinta General Plan.

purpose of reducing the emissions of greenhouse gases by 10 percent below 2005 levels and by 28 percent below 2005 levels in 2035. The 2025 Project would not conflict with AB 32 or the GGRP.
GHG impacts associated with the 2025 Project would be similar to those identified in the Previous Assessments and would be less than significant. No new significant impacts or increase in the severity of any previously identified significant impacts would result from changes to the 2025 Project, new information, or changes to the circumstances under which the 2025 Project will be undertaken.
