DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 1 August 2026
1 Introduction
This document constitutes an Addendum to the certified City of Cathedral City 2040 General Plan Environmental Impact Report (General Plan EIR) (SCH #2018081012), dated July 15, 2019, for the City’s proposed update of Title 9, Planning and Zoning, of the City of Cathedral City Development Code, also referred to as the City’s Zoning Code.

1.1 Project Location
A Development Code Update (“proposed Project” or “Project”) is proposed for the City of Cathedral City (City), located in the central portion of Riverside County, California, within the Coachella Valley. The City encompasses approximately 14,557 acres (approximately 22.7 square miles), with land on both sides of Interstate 10 (I-10). The area north of I-10 and east of the City’s corporate limits is within the City’s Sphere of Influence. The City of Palm Springs borders the City to the west and southwest; the City of Rancho Mirage borders the City to the east and southeast; unincorporated Riverside County borders the City to the north and east (north of I-10); and the City of Desert Hot Springs is located farther to the northwest. The majority of the City is developed with or planned to be developed with residential and commercial uses (approximately 60 percent) with the remainder of the area including industrial, open space and public uses. Refer to Exhibit 1, Regional Project Location.

1.2 Project Description
The Project consists of a technical update to Title 9, Planning and Zoning, of the City of Cathedral City Development Code (herein referred to as “Development Code Update” or “Project”). The Project would bring the City’s Zoning Code into compliance with California Government Code Section 65860(a), which requires that a jurisdiction’s zoning ordinance be consistent with its General Plan and subsequent updates to its General Plan. Therefore, the City is proposing to amend its existing Zoning Code to ensure (1) compatibility with its adopted 2040 General Plan & Active Transportation Plan (adopted July 28, 2021); (2) create consistency with State housing law and reduce regulatory barriers to the construction of housing; (3) reflect changes in State law; (4) create contemporary zoning provisions; (5) make the Zoning Code easier to use and implement; and (6) implement changes to address issues identified by City staff. The City’s updated Zoning Code would therefore implement the goals and policies of the General Plan by regulating the use of land and structures within the City.

This Addendum, therefore, analyzes the changes and potential environmental impacts related to the adoption of the Development Code Update, and is intended to demonstrate the consistency of the Project with the existing General Plan to comply with CEQA. The City’s 2040 General Plan underwent extensive environmental review in the form of an Environmental Impact Report (EIR) (SCH #2018081012). The EIR for the City of Cathedral City General Plan is a comprehensive document and includes discussion of alternatives and growth-inducing impacts associated with urban development in the City at the time it was developed. In particular, and in line with Public Resources Code Section 21083.3, this Addendum assesses whether the Development Code Update, as a policy and programs document, includes impacts not addressed or previously analyzed in the General Plan EIR.

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 2 August 2026

1.3 Discretionary Actions
Implementation of the Development Code Update would require the following discretionary actions by the City of Cathedral City Planning Commission and/or City Council:
• Amendment of the Cathedral City Municipal Code (CCMC) to add the updated Zoning Code (Title 9); and
• Adoption of this Addendum to the certified General Plan EIR.

1.4 Consistency Analysis
The City, as the lead agency for the Project, must determine if or to what degree the proposed Development Code Update (current Project) requires additional documentation under CEQA. CEQA authorizes a Lead or Responsible Agency to prepare an addendum to the EIR if a proposed action is within the scope of a previously analyzed Project and none of the conditions described in State CEQA Guidelines Section 15162 requiring the preparation of a Subsequent EIR or State CEQA Guidelines Section 15163 requiring the preparation of a Supplement to an EIR are met. If none of the conditions in Sections 15162 or 15163 are met, then the most appropriate CEQA documentation for the proposed Project is an Addendum to the General Plan EIR under State CEQA Guidelines Section 15164.

1.5 CEQA Compliance

1.5.1 Supplemental or Subsequent EIR
CEQA authorizes a Lead or Responsible Agency to determine if a proposed action is within the scope of a previously analyzed project and none of the conditions described in State CEQA Guidelines Section 15162 requiring the preparation of a Subsequent EIR or State CEQA Guidelines Section 15163 requiring the preparation of a Supplement to an EIR are met.

Pursuant to State CEQA Guidelines Section 15162:
(a) When an EIR has been certified or negative declaration adopted for a project, no subsequent EIR shall be prepared for that project unless the lead agency determines, on the basis of substantial evidence in the light of the whole record, one or more of the following:
(1) Substantial changes are proposed in the project which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects;
(2) Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or (3) New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete or the negative declaration was adopted, shows any of the following:
(A) The project will have one or more significant effects not discussed in the previous EIR or negative declaration;
(B) Significant effects previously examined will be substantially more severe than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or
(D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.
(b) If changes to a project or its circumstances occur or new information becomes available after adoption of a negative declaration, the lead agency shall prepare a subsequent EIR if required under subdivision (a). Otherwise the lead agency shall determine whether to prepare a subsequent negative declaration, an addendum, or no further documentation. (c) Once a project has been approved, the lead agency's role in project approval is completed, unless further discretionary approval on that project is required. Information appearing after an approval does not require reopening of that approval. If after the project is approved, any of the City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 6 August 2026
conditions described in subdivision (a) occurs, a subsequent EIR or negative declaration shall only be prepared by the public agency which grants the next discretionary approval for the project, if any. In this situation no other responsible agency shall grant an approval for the project until the subsequent EIR has been certified or subsequent negative declaration adopted. (d) A subsequent EIR or subsequent negative declaration shall be given the same notice and public review as required under Section 15087 or Section 15072. A subsequent EIR or negative declaration shall state where the previous document is available and can be reviewed.

Pursuant to State CEQA Guidelines Section 15163:
(a) The lead or responsible agency may choose to prepare a supplement to an EIR rather than a subsequent EIR if:
(1) Any of the conditions described in Section 15162 would require the preparation of a subsequent EIR, and
(2) Only minor additions or changes would be necessary to make the previous EIR adequately apply to the project in the changed situation. (b) The supplement to the EIR need contain only the information necessary to make the previous EIR adequate for the project as revised.
(c) A supplement to an EIR shall be given the same kind of notice and public review as is given to a draft EIR under Section 15087.
(d) A supplement to an EIR may be circulated by itself without recirculating the previous draft or final EIR.
(e) When the agency decides whether to approve the project, the decision-making body shall consider the previous EIR as revised by the supplemental EIR. A finding under Section 15091 shall be made for each significant effect shown in the previous EIR as revised.

Based on the analysis provided in Section 4 of this document, the proposed Project does not involve changes that will result in new or increased environmental effects, new significant impacts, or the need for additional or increased mitigation beyond those identified in the previously certified General Plan EIR; thus, none of the conditions identified in State CEQA Guidelines Section 15162 or 15163 will be triggered by the Project. Therefore, the City may analyze the Project in an Addendum according to State CEQA Guidelines Section 15168 to document consistency with the approved EIR. The Addendum must be supported by substantial evidence.

1.5.2 Addendum to an EIR
Provisions related to preparing an Addendum to an EIR are found in Section 15164 of the State CEQA Guidelines, subsections (a) and (b) as summarized below:
(a) The lead agency or responsible agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred. (b) An addendum to a certified EIR may be prepared if only minor technical changes or additions are necessary or none of the conditions described in Section 15162 calling for the preparation of a subsequent EIR or negative declaration have occurred. To determine if an Addendum is the most appropriate CEQA compliance document for the proposed project, the project will be City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 7 August 2026
compared to the requirements of State CEQA Guidelines Section 15162 (sub-sections 1 through 3 below). When an EIR has been certified, no subsequent EIR shall be prepared for that project unless the lead agency determines, on the basis of substantial evidence in the light of the whole record, one or more of the following occurs.
(1) Substantial changes are proposed in the project which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects. (2) Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects.
(3) New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete, shows any of the following:
(A) The project will have one or more significant effects not discussed in the previous EIR;
(B) Significant effects previously examined will be substantially more severe than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or
(D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.

In addition, the project must be evaluated relative to the State CEQA Guidelines Section 15163 regarding preparation of a supplement to an EIR rather than a subsequent EIR. The lead or responsible agency may choose to prepare a supplement to an EIR rather than a subsequent EIR if: (1) Any of the conditions described in Section 15162 would require the preparation of a subsequent EIR, and (2) Only minor additions or changes would be necessary to make the previous EIR adequately apply to the project in the changed situation.

1.5.3 Summary of Results
The analyses in Sections 4.1 through 4.15 of this document establish that the proposed project is consistent with the General Plan EIR and would not result in new or more severe impacts when compared to those identified in the General Plan EIR.

The changes associated with the proposed Project are best documented using an Addendum to the General Plan EIR consistent with State CEQA Guidelines Section 15164. The City has, therefore, prepared this Addendum to evaluate the changes proposed by the Project. If approved, a Notice of Determination (NOD) will be filed with the County Clerk and State Clearinghouse to fully document this CEQA compliance action.

2 Project Context

2.1 City of Cathedral City General Plan
State law mandates that each town, city, and county in California adopt "a comprehensive, long-term general plan,” for the physical development of its planning area. The Cathedral City General Plan planning area includes all lands within the City limits and Sphere of Influence (SOI). The purpose of the General Plan is to plan for important community issues such as new growth, housing needs, and environmental protection. Furthermore, the General Plan is used to project future demand for services such as sewer, water, roadways, parks, and emergency services.

The Cathedral City General Plan, adopted in July 2021, is a long-term document which identifies the community’s vision for the future and provides a framework that will guide decisions on growth, development, and conservation of open space and resources in a manner that is consistent with the quality of life desired by the City’s residents and businesses.

The General Plan policy document contains the goals and policies that will guide future decisions within the City and identifies action items (implementation measures) to ensure the vision and goals of the General Plan are carried out. The General Plan also contains a Land Use Map, which serves as a general guide to the distribution of land uses throughout the City.

State law requires that every General Plan, at a minimum, address certain subject categories (called "elements"), which include land use, circulation, housing, conservation, open space, noise, safety, and environmental justice. A General Plan may also address other subjects that are of importance to the community future, such as sustainability, community design, and public art. Cathedral City’s General Plan includes the following elements:
• Land Use Element
• Circulation and Mobility Element
• Housing Element
• Parks and Recreation Element
• Community Design Element
• Arts and Culture Element
• Economic and Fiscal Health Element
• Environmental Justice Element
• Healthy and Sustainable Community Element
• Open Space and Conservation Element
o Biological Resources Sub-Element
o Cultural Resources Sub-Element
o Water Resources Sub-Element
o Energy and Mineral Resources Sub-Element
• Air Quality and Climate Stability Element

2.3 Development Code Update
The Development Code Update represents a comprehensive modernization of the City’s regulatory framework, aligning land use and development standards with the vision set forth in the Cathedral City 2040 General Plan. While the following highlights capture many of the most significant changes, they are not exhaustive. Collectively, these updates are intended to advance implementation of the General Plan, stimulate economic development, reflect City Council priorities, ensure consistency with evolving State and Federal law, and incorporate best practices in contemporary planning and urban design. The result is a clearer, more flexible, and more predictable Code that supports high-quality development, improves livability, and better responds to the City’s unique context. The proposed major updates and improvements include the following:
• Creation of a Unified Downtown Mixed-Use Zone (MU-DT):
o The existing DRN and MXC zoning districts have been consolidated into a single Mixed-Use Downtown (MU-DT) zone. This change simplifies the regulatory framework for the downtown area, encourages a cohesive mix of uses, and supports a more vibrant, walkable urban core. • Incorporation of Mixed-Use Zone (MU-N and MU U) and Industrial (I-1) Zoning Districts from the North City Specific Plan (NCSP):
o The existing mixed-use and industrial zoning districts were carried over from the North City Specific Plan (NCSP) and incorporated into Division 2.
• Renaming of Residential Zoning Districts:
o Residential zones have been renamed to more clearly communicate the intended development typologies and density ranges. This improves transparency for property owners, developers, and residents, and aligns zoning terminology with modern planning conventions. • Alignment of Parcel Sizes with General Plan Densities:
o Minimum parcel size requirements have been recalibrated across all zoning districts to ensure consistency with allowable densities in the 2040 General Plan. This resolves existing inconsistencies and enables more predictable and achievable development outcomes. • Consolidation of Commercial Zoning Districts:
o Multiple commercial zones have been streamlined into a more cohesive single zoning district that better reflects the range and intensity of commercial uses citywide, reducing redundancy and improving usability of the Code.
• Creation of the Professional Office (PO) District:
o Business park and office zones have been merged into a single Professional Office (PO) zoning district, providing flexibility for a range of office and employment-generating uses while simplifying zoning classifications.

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 11 August 2026
• Elimination of the Commercial Tourist and Recreation (CTR) District:
o The Commercial Tourist and Recreation (CTR) zoning district has been removed and incorporated into the Mixed-Use Downtown Zoning District. Given its limited geographic application, this change ensures consistency with surrounding land uses and supports integrated development patterns.
• Citywide Land Use Consolidation:
o Land use categories have been standardized and consolidated across zoning districts to reduce duplication, clarify permitted uses, and improve administrative efficiency. • Streamlined Permitting Processes:
o The Code increases the number of ministerial approvals, reducing discretionary review where appropriate. This facilitates faster review by City staff and review bodies, reduces uncertainty, and supports economic development.
• Centralized Development and Design Standards:
o Similar standards have been consolidated into unified sections, making the Code easier to navigate and apply.
• New Shade Standards:
o A new section addresses shade provisions to mitigate the urban heat island effect and enhance comfort in the desert environment. These standards apply to both private development and the public realm and will be supplemented by additional forthcoming regulations. • Updated Landscaping Requirements:
o Landscaping standards now require layered planting (trees, shrubs, and groundcover), prohibit artificial turf, and establish objective limits on impervious surfaces. The standards also incorporate water-efficient landscaping practices consistent with regional water district guidance. • Refined Open Space Standards:
o Open space requirements have been enhanced, including updated screening standards for private open space to improve usability and privacy in residential developments. • Revised Development Standards:
o Setbacks and other dimensional standards have been reduced or adjusted in both residential and commercial zoning districts to encourage more efficient land use and better site design. • Modernized Parking Standards:
o Parking requirements have been reduced where appropriate to address over-supply, particularly in commercial areas. New procedures and findings provide a clear pathway for parking reductions, reflecting community input gathered during 2025 walking tours. • Innovative Parking Strategies:
o The Code introduces flexible solutions such as valet parking and shared parking arrangements for multi-tenant developments, promoting more efficient use of land.

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 12 August 2026
• Accessory Use Enhancements:
o New standards address accessory uses such as storage containers, providing clear criteria for their placement and use.
• Updated Lighting Standards:
o Lighting regulations have been modernized to promote dark sky principles, reduce light pollution, and improve energy efficiency. Standards include curfews, dimming requirements, shielding, and automated controls.
• Expanded and Tiered Use Permissions:
o Use regulations now better reflect intensity by scaling permissions (by right, ministerial, or conditional) based on factors such as size and operational characteristics. • New and Updated Use-Specific Standards (Division 4):
o Several new and revised sections provide detailed guidance for specific uses, including:
 Integration of the recently adopted Accessory Dwelling Unit (ADU) ordinance  Standards for outdoor storage, displays, and sales
 Updated regulations for drive-through and drive-in uses (circulation, stacking, hours, screening)
 New standards for alcohol beverage manufacturing
 Regulations for community gardens, including operations and maintenance  Development standards for bed and breakfast inns
 Expanded and modernized home occupation allowances
 New standards for small grocery stores and neighborhood markets to maintain communityserving scale  Regulations for restricted retail uses with buffers from sensitive receptors and design measures to deter crime
 Updates to Density Bonus provisions to reflect current State law • Planned Unit Development (PUD) Overhaul:
o The Planned Unit Development (PUD) ordinance has been comprehensively revised to improve clarity, flexibility, and alignment with current development practices. • Objective Standards for Multifamily and Mixed-Use Development:
o New objective design and development standards provide clear expectations and support streamlined approvals.
• Updated Subdivision Regulations:
o The subdivision ordinance has been fully modernized to align with State law and eliminate reliance on outdated Riverside County standards.

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 13 August 2026
• Expanded Definitions:
o Definitions have been clarified and expanded to reduce ambiguity and improve consistent interpretation of the Code.
• Refined Permit Structure:
o The permit framework has been reorganized and clarified, including updates to discretionary processes such as PUD approvals.
• Removal of Outdated Provisions:
o Obsolete language, standards, and terminology have been eliminated to reflect current policy direction and priorities.
• Enhanced Use of Tables and Graphics:
o The Code incorporates more visual tools to improve readability, usability, and comprehension. • Improved Organization and Formatting:
o A restructured format enhances navigation and clarity for all users of the Code. • Implementation of the 2040 General Plan Land Use Framework:
o The updated Code directly translates the General Plan’s land use vision into actionable regulations, ensuring consistency between policy and implementation.

2.4 Preliminary Environmental Constraints
The Development Code Update, in and of itself, does not propose or approve any specific development project. Instead, the proposed project codifies zoning rules, standards, processes, and procedures that guide future growth in Cathedral City. Each future development project would be subject to separate review to determine potential impacts on the environment related to each project as potential impacts are location-specific and cannot be assessed in a meaningful way until a project site and development proposal are identified. Furthermore, development within the City may be approved ministerially or by right under existing State law (i.e., Government Code Section 65852.2 and 65913.4, Assembly Bill 2011, Senate Bill 423, etc.). Pursuant to State CEQA Guidelines Section 15268, Ministerial Projects, ministerial approvals are statutorily exempt from CEQA, and no project-level CEQA review would be required. This Addendum does not rely on subsequent project-level CEQA review to assess the impact associated with such projects. Instead, the proposed Development Code Update would identify applicable General Plan EIR mitigation measures as a standard that would apply during the plan check process to both ministerial and discretionary projects in compliance with City procedures.

When a specific development proposal is considered for approval, that project would be subject to adopted development guidelines and standards and be required to incorporate applicable mitigation measures and alternatives developed in the General Plan EIR certified in 2019 (in accordance with State CEQA Guidelines Section 15168[c][3]). If a subsequent activity (in this case a specific development proposal that requires discretionary approval) would have effects not identified in the program EIR (the General Plan EIR and this Addendum), the lead agency must prepare additional CEQA documentation. This Addendum evaluation includes the analysis of the changes and potential impacts related to the adoption of the Development Code Update. This Addendum evaluation is intended to demonstrate the project’s consistency with the existing City of Cathedral City General Plan and General Plan EIR to satisfy the requirements of CEQA. In particular, and pursuant to Public Resources Code Section 21083.3, this Addendum evaluation assesses whether the updated Zoning City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 14 August 2026
Code, as a policy and programs document, includes impacts not addressed or analyzed as significant effects in the certified EIR.

3.2 Determination
On the basis of this initial evaluation:

I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared.

I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.

I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required.

I find that the proposed project MAY have a “potentially significant impact” or “potentially significant unless mitigated” impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets.

An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed.

I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

4.1 Aesthetics
Summary of Analysis in the General Plan EIR
Aesthetics, visual, and scenic resources are discussed in Section 2.2, Aesthetics, of the General Plan EIR. The General Plan EIR states that natural scenic vistas within the City includes the Santa Rosa, San Jacinto, and Little San Bernardino Mountains. Additionally, other notable scenic vistas includes, but is not limited to, the Cathedral Cove, backdrop of the Santa Rosa Mountains, Edom Hill, and Indio Hills.

Implementation of the General Plan EIR would encourage new development in areas that are vacant and redevelopment in existing urbanized areas. The General Plan EIR determined that the General Plan includes policies and programs that protect the existing view and maintain existing scenic vistas.

Additionally, the Project includes development standards to reduce impact on scenic vistas from new and redevelopment projects (Community Design Element Policies 1.1, 1.2, and 2.1). Furthermore, the General Plan includes policies that ensure the harmony of the development design and the natural environment as well as the preservation of natural resources (Community Design Element policies 2.1,

2.2, and 3.2; Open Space and Conservation Element policies 4 and 11). With implementation of applicable General Plan policies, the General Plan EIR determined that implementation of the General Plan would have a less than significant impact on scenic vistas.

With respect to state scenic highways, the General Plan EIR determined that no state scenic highways run through the city. As such, the General Plan EIR determined that implementation of the proposed General Plan would not damage scenic resources along or visible from a state scenic highway.

Nevertheless, the General Plan EIR stated that scenic resources in the form of streetscapes, parks, and open spaces are vital resources of the City’s scenic corridors. Thus, the policies from the General Plan (Community Design Element Policies 1.1, 1.2, 2.1, and 2.2) would ensure the protection and enhancement of scenic resources along the city’s scenic corridor. With implementation of applicable General Plan policies, the General Plan EIR determined that implementation of the General Plan would have a less than significant impact on scenic resources along state scenic highways.

The General Plan EIR determined that policies and programs in the General Plan are consistent and would enhance the existing character of development in the city. Specifically, the Community Design Element outlines policies and regulations that would enhance the visual character along public rightsof-way. Furthermore, the General Plan EIR determined that the City’s Architectural Review Committee would review the architectural and landscaping design for all future development. In addition to conformance with the Community Design Element, all future development would adhere to design standards and guidelines contained in the Cathedral City Municipal Code (CCMC). With adherence to General Plan policies, architectural and landscape review by the Architectural Review Committee, and adherence to design standards and guidelines, the General Plan EIR determined that implementation and buildout of the General Plan would have a less than significant impact on the visual character of the City.

The General Plan EIR states that light and glare impacts are associated with increased urbanization and that most of the planning area are developed. The General Plan would encourage development patterns similar to existing conditions. Nevertheless, the General Plan EIR states that regulations and policies contained in the CCMC Chapter 9.89, Outdoor Lighting Standards, and General Plan (Community Design Element Policy 2.3) would minimize light and glare impacts associated with existing and new development. With implementation of applicable regulations and General Plan policies, the General Plan EIR determined that implementation of the General Plan would have a less than significant impact on light and glare impacts within the City.

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 19 August 2026
The General Plan would encourage the continued urbanization within the city and would assist in minimizing aesthetic impacts through applicable General Plan policies, Architectural Review Committee review, and regulations contained in the CCMC. While the General Plan EIR determined that the General Plan would have a less than significant impact on aesthetics (i.e., impacts on scenic vistas, scenic corridors, visual character, light and glare), Mitigation Measures AES-1 through AES-11, as described below in “Applicable General Plan EIR Mitigation Measures,” would ensure that impacts related to aesthetic continue to be less than significant.

Proposed Project Analysis
Policies and actions in the General Plan that were referenced in the General Plan EIR would reduce impacts to the greatest extent possible. These policies and actions would continue to be required with implementation of the Development Code Update. The proposed Project would update the Development Code for consistency with the 2040 General Plan. The update would result in the creation of new zoning districts as well as the elimination of existing districts; the renaming of existing districts; the consolidation of existing districts; as well as the modification or modernization of requirements for development and land uses within various other districts. However, these districts and their standards would be consistent with the 2040 General Plan. The proposed Project would update but not eliminate the fundamental regulations and requirements of the Development Code, such as meeting design and development standards. The proposed Project would align the Development Code with the General Plan and ensure it regulates the types of land uses and development envisioned in the General Plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same aesthetic impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

4.2 Agriculture and Forestry Resources
Summary of Analysis in the General Plan EIR
Agriculture and forestry resources are discussed in Section 2.3, Agriculture and Forestry Resources, of the General Plan EIR. The General Plan EIR identified that there are no prime or unique farmlands, or farmlands of statewide importance in the city, nor are there any lands that are under a Williamson Act contract. There are also no forest lands in the city. Due to the lack of these resources in the city, the General Plan EIR concluded that no impact would occur on such resources and no mitigation is required.

Thresholds of Significance
The following significant thresholds or criteria are derived from Appendix G of CEQA, which is used to determine if and to what extent a project may have a potentially significant impact on agriculture and forestry resources. The City would consider the proposed Project to have a significant effect on agriculture and forestry resources if it is determined that the Project will:
a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance, as shown on the maps pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use.
b) Conflict with existing zoning for agricultural use, or a Williamson Act Contract. c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g)).
d) Result in the loss of forest land or conversion of forest land to non-forest use. e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to nonforest use.

Proposed Project Analysis
Since the proposed Project involves the same areas as the planning area identified in the General Plan EIR, and there are no prime or unique farmlands, farmlands of statewide importance, Williamson Act lands, or forest lands in the area, the proposed Project would similarly no have impact on such resources. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

No mitigation measures were identified in the General Plan EIR for agriculture and forestry resources.

4.3 Air Quality and Greenhouse Gases
Summary of Analysis in the General Plan EIR
Air Quality
Air quality impacts are discussed in Section 2.4, Air Quality and Greenhouse Gases, of the General Plan EIR. The City is located within the Salton Sea Air Basin (SSAB) which is governed by the South Coast Air Quality Management District (SCAQMD). As it relates to air quality plan consistency, the General Plan EIR states that all development within the SSAB, including the development within the City, would be subject to the 2016 SCAQMD Air Quality Management Plan and 2003 PM10 Coachella Valley State Implementation Plan. Conformity with an adopted air quality plan is determined if a project adheres to the requirement of the South Coast Air Quality Management Rule Book and Air Quality Management Plan. A project is conforming if it complies with all applicable rules and regulations, adopted and forthcoming control measures, and is consistent with the growth forecasts.

According to the General Plan EIR, the city has a population of approximately 54,4666 residents. Based on the Southern California Association of Governments (SCAG), the city’s population forecast for the year 2040 would be approximately 68,100 residents. Based on the additional 33,396 dwelling units under the General Plan and the city’s average of 3.16 persons per household, full buildout of the General Plan would result in a population of approximately 159,998 residents. As such, the General Plan EIR determined that the General Plan’s population forecast would not be consistent with the SCAG’s population projection. An increase in population results in a correlated increase in the level of air quality emissions and thus, the General Plan would result in higher levels of air pollution than originally forecasted. Thus, the General Plan EIR determined that the General Plan has the potential to conflict with or obstruct implementation of future Air Quality Management Plans.

The General Plan includes policies and programs (Air Quality and Climate Stability Element Policies 1, 2, 4, 5, 6, 8, and Environmental Justice Element Policy 6.1) that would reduce impacts associated with construction and operational air pollutant emissions. Additionally, the General Plan EIR determined that adherence to the City’s Climate Action Plan and Green for Life program are expected to substantially reduce emissions of air quality pollutants and reduce the per capita emission contribution. Furthermore, the General Plan EIR implemented Mitigation Measures AQ-1 through AQ-22, as described below in “Applicable General Plan EIR Mitigation Measures,” which includes City programs designed to avoid and or reduce air quality impacts to less than significant levels. With implementation of policies, programs, adherence to the City’s Climate Action Plan and Green for Life program, and implementation of Mitigation Measures AQ-1 through AQ-22, the General Plan EIR determined that impacts were reduced to less than significant.

The General Plan EIR states that the SSAB is non-attainment for ozone (O3) and particulate matter (PM10). Construction and operational emissions associated with the buildout of the General Plan would result in increased emissions of criteria pollutants that the SSAB is non-attainment. The General Plan EIR determined that construction of the General Plan would result in short-term emissions of various air pollutants that may have the potential to substantially increase criteria pollutants. However, the General Plan EIR was unable to quantify emissions associated with construction since information pertaining to specific development projects would be required to quantify construction emissions. Nevertheless, the General Plan includes policies (Air Quality and Climate Sustainability Element Policy 1) that would control construction emissions. Furthermore, the General Plan EIR include Mitigation Measures AQ-5 through AQ-8, as described below in “Applicable General Plan EIR Mitigation Measures,” which would reduce construction-related emissions. Lastly, construction of future new development would be subject City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 23 August 2026
to applicable SCAQMD rules and regulations. With implementation of policies, Mitigation Measures AQ5 through AQ-8, and SCAQMD rules and regulations, the General Plan EIR determined that construction impacts were less than significant.

The General Plan EIR states that daily activities during the operation of future development would result in emissions from the use of electricity, natural gas, area sources (use of consumer products, architectural coating, landscaping, etc.), and mobile vehicles. The SCAQMD does not have a methodology adopted to evaluate the cumulative emissions generated by multiple cumulative projects such as the proposed General Plan. However, the SCAQMD recommends the evaluation of a project’s potential contribution to cumulative impacts. Table 2, Existing and Proposed Land Use Operational Emissions, displays the existing and proposed operational emissions. As shown in Table 2, operational air quality emissions associated with the General Plan would have the potential to result in a cumulatively considerable net increase of carbon monoxide (CO), nitrogen oxides (NOx), particulate matter less than 10 micrometers (PM10), particulate matter less than (PM2.5), and reactive organic compounds (ROG). The General Plan EIR determined that most air quality pollutant emissions originate from mobile sources. The General Plan includes policies (Community Design Element Policy 5.1 and Open Space and Conservation Element Policy 2 and 5) that promote the reduction of mobile emissions through transportation planning.

Notes: CO = carbon monoxide; NOx = nitrogen oxides; ROG = reactive organic compounds; SOx = sulfur oxides; PM10 = particulate matter less than 10 micrometers; PM2.5 = particulate matter less than 2.5 micrometers Nevertheless, individual projects associated with the buildout of the General Plan would be evaluated on a project-by-project basis for their potential to result in a cumulatively considerable contribution to non-attainment criteria pollutants. Individual projects would have project-specific information and would be required to address, and to the extent feasible, mitigate any significant air quality impacts to a less than significant level. Additionally, the General Plan EIR determined that implementation of Mitigation Measure AQ-6, as described below in “Applicable General Plan EIR Mitigation Measures,” would help City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 24 August 2026
reduce project-specific air quality emissions. With implementation of policies and Mitigation Measure AQ-6, the General Plan EIR determined that the General Plan would not result in a cumulative considerable net increase of criteria pollutants on a case-by-case basis.

As it relates to the exposure of substantial pollutant concentrations to sensitive receptors, the General Plan EIR determined that the land use plan of the General Plan was designed to provide a buffer between sources of emissions and sensitive receptors. In addition to the land use plan, the General Plan includes a program (Air Quality and Climate Sustainability Element Program 3.C) which requires the City or project applicant to evaluate health risks when proposed development would locate new sensitive receptors near existing sources of substantial toxic air contaminants (TACs) or when proposed sources of TACs are located near existing sensitive receptors. Where proposed development would not meet California Air Resource Board’s (CARB) recommended separation distances between TAC sources and sensitive receptors, the City would require the applicant to demonstrate that TAC impacts remain below the carcinogenic threshold and below the non-carcinogenic threshold. Risk reduction measures would also be implemented such as locating TAC-emitting land uses as far as practicable from sensitive receptors, requiring diesel truck shutoff after five minutes of idling, and incorporating idlereduction technologies, electrified truck parking, and alternative energy sources for transport refrigeration units. Individual development projects would be required to address and, to the extent feasible, mitigate any significant air quality impacts to a less than significant level. With implementation of policies and programs, the General Plan EIR determined that the General Plan would not expose sensitive receptors to substantial pollutant concentrations and impacts were determined to be less than significant.

As it relates to odors, the General Plan EIR determined that the buildout of the General Plan would introduce land uses that have the potential to generate objectionable odors such as cannabis cultivation.

Nevertheless, CCMC Section 5.88.125, Odor Control Plan, requires that an odor control plan would be prepared and designed as performance-based systems for each cannabis business so cannabis-related odors are not detected off site. The odor control plan would identify administrative controls, engineering controls, process parameters, maintenance requirements, and training necessary to control cannabis odor. Furthermore, all future development would be evaluated on a project-by-project basis on their potential to generate odors and implementation of project specific mitigation or features. As such, the General Plan EIR determined that implementation of the General Plan would be unlikely to result in objectionable odors affecting a substantial number of people and a less than significant would occur.

Greenhouse Gases
Greenhouse gas impacts are discussed in Section 2.4, Air Quality and Greenhouse Gases, of the General Plan EIR. As it relates to construction greenhouse gas (GHG) emissions, the General Plan EIR determined that construction GHG emissions would directly or indirectly result in a temporary impact on the local and regional air quality. However, the General Plan EIR was unable to quantify GHG emissions associated with construction since information pertaining to specific development projects would be required to quantify construction GHG emissions individually. Future projects would be evaluated on a project-by-project basis to determine construction GHG impacts. Nevertheless, the General Plan EIR determined that the generation of GHG emissions from the buildout of the General Plan would be shortterm and construction impacts were determined to be less than significant.

As it relates to operational GHG emissions, the General Plan EIR states that five emission source categories (energy use, water use, solid waste disposal, area emissions, and mobile emissions) were quantified to determine GHG emissions. Existing operational GHG emissions from the existing General Plan land use plan and proposed land use plan were quantified in Table 3, 2040 Operational GHG Emissions Comparison. As shown in Table 3, the proposed General Plan would increase the City’s City of Cathedral City

existing GHG emissions and was determined to be inconsistent with Assembly Bill 32 GHG targets for the years of 2020, 2030, and 2050. Additionally, the proposed General Plan was also determined to be inconsistent with the GHG reduction targets in the City’s Climate Action Plan (CAP).

1. GHG emissions are presented as metric tons of carbon monoxide equivalent (CO2e) per year. GHG emissions are based on total “unmitigated” GHG emissions projections for existing and proposed General Plan Land Use.

2. Numbers within parentheses represent a net decrease from existing conditions.

3. Per capita assumptions based on the population estimates for the year of 2040 in the General Plan EIR. According to the General Plan EIR, the 2040 population would be reduced by 68,100 under existing conditions and 159,998 under the proposed land use conditions.

As such, the General Plan EIR determined that operational activities from the full buildout of the General Plan would result in the generation of GHG emissions that would have a significant impact on local and regional air quality. The General Plan includes policies (Air Quality and Climate Sustainability Element Policies 5, 6, 7, and 10) to reduce GHG emissions through the implementation of applicable CAP policies, promotion of alternative energy, and usage of alternative modes of transportation. Furthermore, the General Plan EIR implemented Mitigation Measures AQ-9 through AQ-42, as described below in “Applicable General Plan EIR Mitigation Measures,” which would reduce GHG emissions to the greatest extent possible. Nevertheless, based on projected GHG emissions, the General Plan EIR determined that the implementation of the General Plan would generate GHG emissions that would have a significant impact on the environment. As such, operational impacts were determined to be significant and unavoidable.

As it relates to conflicting with applicable plan, policy or regulation adopted for the purpose of reducing the emissions of GHG, the General Plan EIR determined that the proposed General Plan would result in higher GHG emissions when compared to existing land uses. Additionally, the buildout GHG emissions would fail to achieve State GHG reduction targets for the years of 2020, 2030, and 2050.

GHG emissions related to the buildout of the General Plan could be reduced with technology advancement, Best Management Practices (BMPs), and adherence to existing SCAQMD rules and regulations. The General Plan also includes policies (i.e., Air Quality and Climate Stability Element Policy 10, Hazards and Safety/Community Element Policy 2.2, Community Development Element Policy

3.1 and 5.1, and Open Space and Conservation Element Policy 1 through 6) that promote GHG reductions through transportation and land use planning, efficient use of energy resources, and adherence to policies, regulations, and plans. All future development would be evaluated on a projectby-project basis on their potential to generate GHG emissions and adherence to applicable plans, City of Cathedral City

policies, and regulations adopted for the purpose of reducing GHG emissions. Furthermore, the General Plan EIR implemented Mitigation Measures AQ-9 through AQ-42, as described below in “Applicable General Plan EIR Mitigation Measures,” which would reduce GHG emissions to the greatest extent possible. Nevertheless, the General Plan EIR determined that the proposed General Plan would still generate GHG emissions that are inconsistent with State reduction targets and impacts were determined to be significant and unavoidable.

The City would consider the proposed Project to have a significant effect on air quality if it is determined that the project will:
a) Conflict with or obstruct implementation of the applicable air quality plan. b) 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.
c) Expose sensitive receptors to substantial pollutant concentrations. d) Result in other emissions, such as those leading to odors adversely affecting a substantial number of people.

Additionally, the City would consider the proposed Project to have a significant effect on greenhouse gas emissions if it is determined that the project will:
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.

Proposed Project Analysis
Air Quality
Policies and actions in the General Plan that were referenced in the General Plan EIR would reduce impacts to the greatest extent possible. These policies and actions would continue to be required with implementation of the Development Code Update. The proposed Project would update the Development Code for consistency with the 2040 General Plan. The update would result in the creation of new zoning districts as well as the elimination of existing districts; the renaming of existing districts; the consolidation of existing districts; as well as the modification or modernization of requirements for development and land uses within various other districts. However, these districts and their standards would be consistent with the 2040 General Plan. The proposed Project would update but not eliminate the fundamental regulations and requirements of the Development Code, such as meeting design and development standards. The proposed Project would align the Development Code with the General Plan and ensure it regulates the types of land uses and development envisioned in the General Plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same air quality impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed City of Cathedral City

DEVELOPMENT CODE UPDATE

Project would not result in increased density or more development than was envisioned in the General Plan.

The Development Code Update, in and of itself, does not propose specific projects but aligns the Code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts on air quality emissions, expose individuals to substantial pollutants, or produce odors.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

4.4 Biological Resources
Summary of Analysis in the General Plan EIR
Biological resources are discussed in Section 2.5, Biological Resources, of the General Plan EIR. The General Plan EIR determined that while implementation of projects proposed under the General Plan may have the potential to result in impacts to special status species, impacts would be less than significant with implementation of mitigation measures. Future development projects facilitated under the General Plan would be evaluated on a project-by-project basis for potential adverse impacts to sensitive species and impacts to special status species would be mitigated through the payment of Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) mitigation fees (Mitigation Measures BIO-1 and BIO-2). The City is a Permittee to the CVMSHCP and cooperates with the Agua Caliente Band of Cahuilla Indians to implement the Tribal Habitat Conservation Plan (HCP) on Tribal lands within city boundaries. The General Plan includes Programs 1.B, 1.D, 1.E, and 4.A that provide for the City’s continued participation in both HCPs, including requiring future development projects to pay local development mitigation fees and protection of CVMSHCP Conservation Areas through implementation of land use adjacency guidelines (Mitigation Measures BIO-1 and BIO-2). In addition, land use adjacency guidelines would be implemented for projects within or adjacent to CVMSHCP Conservation Areas (Mitigation Measure BIO-1). Focused species surveys would be required in compliance with applicable state and federal requirements, as described below in “Applicable General Plan EIR Mitigation Measures” in Mitigation Measures BIO-3 through BIO-6.

As it relates to riparian habitat, the General Plan EIR concluded that implementation of projects proposed under the General Plan would have no or a limited potential impact on riparian habitat located in the City’s planning area, and development opportunities near riparian habitat in the planning area are limited. Along the East and West Cathedral Canyon Channels, land on the Cove side of the channels is already developed, and land on the mountain side of the channels is designated as Open Space. Along the Whitewater River, the channel itself is designated as Open Space, and most adjacent parcels are already developed. Nonetheless, the possibility exists for additional development to occur in the vicinity of riparian habitat. Impacts would be minimized by implementation of General Plan Biological Resources Sub-Element Policy 2, which requires the City to evaluate development projects for their impacts on existing habitat and wildlife, and for the land’s value as viable open space. The City may require sitespecific biological assessments to evaluate potential impacts to riparian habitat and the need for mitigation measures. Project-specific impacts would be less than significant with implementation of Mitigation Measures BIO-7 through BIO-10, described below in “Applicable General Plan EIR Mitigation Measures.”
As it relates to jurisdictional waters and wetlands, no designated wetlands have been identified in the planning area. Nonetheless, Policy 10 of the General Plan Water Resources Sub-Element requires new development to protect the quality of water bodies and natural drainage systems through sound design, source controls, storm water treatment, runoff reduction measures, and BMPs. As warranted based on location, proximity to potential wetlands, and other project-specific characteristics, the City may require assessments of hydrologic, soils and habitat conditions to determine whether and to what extent future development projects will impact wetlands, as well as the need for mitigation (see Mitigation Measures BIO-7 through BIO-10).

Relative to migratory wildlife corridors, most parcels on the valley floor in the General Plan area are developed and surrounded by elements of the built environment, including buildings, roads, walls and fences, and utility infrastructure. Any wildlife migratory corridors that may have existed have been largely removed or interrupted by urban development. The habitat value of scattered undeveloped parcels may City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 33 August 2026
have been diminished by the edge effects of surrounding development, such as trash dumping, offhighway vehicle use, and the presence of domestic pets. They are not known to serve as notable wildlife nursery sites but could serve as nesting sites for birds. Future development facilitated by the General Plan could impact nesting birds if construction occurs during nesting seasons; however, implementation of Migratory Bird Treaty Act (MBTA) surveys (Mitigation Measure BIO-4) would reduce potential impacts to less than significant levels.

Thresholds of Significance
The following significant thresholds or criteria are derived from Appendix G of CEQA, which is used to determine if and to what extent a project may have a potentially significant impact on biological resources. The City would consider the proposed Project to have a significant effect on biological resources if it is determined that the Project will:
a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service.
b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service.
c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means.
d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites.
e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance.
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same biological resources impacts from new development as evaluated in the certified General Plan EIR. In addition, City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 34 August 2026
the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

The Development Code Update, in and of itself, does not propose specific projects but aligns the Code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts to biological resources such as special status species, riparian or sensitive habitats, protected wetlands, wildlife corridors, or conflict with local policies, ordinances, or conservation plans.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

BIO-1 Mitigation Related to the CVMSHCP To the extent applicable, the City shall comply with all terms and conditions of the CVMSHCP and Implementing Agreement including, but not limited to: implementation of the “Land Use Adjacency Guidelines” as described in Section 4.5 of the CVMSHCP and collection of approved CVMSHCP land development mitigation fees.

BIO-2 Mitigation Related to the Tribal HCP The City shall cooperate and coordinate with the Agua Caliente Band of Cahuilla Indians to help assure the development on Tribal lands in the planning area conforms to the provisions of the Tribal Habitat Conservation Plan.

BIO-3 Mitigation Related to Burrowing Owl For projects that contain suitable habitat for Burrowing Owl, a “take avoidance survey” for the burrowing owl no less than 14 days (in accordance with the Staff Report on Burrowing Owl Mitigation [CDFW 2012]) and no more than 30 days prior to groundbreaking activities shall be required. Additionally, a final survey must be conducted within 24 hours of the initiation of ground disturbance activities in accordance with the CDFW 2012 protocol.
a. If no burrowing owls are detected during those surveys, implementation of ground disturbance activities could proceed without further consideration of this species assuming there is no lapse between the surveys and construction as the protocol states “time lapses between Project activities trigger subsequent take avoidance surveys including but not limited to a final survey conducted within 24 hours prior to ground disturbance."
b. If burrowing owls are detected during the take avoidance surveys, avoidance and minimization measures would then be required and could include the establishment of a buffer zone, the passive or active relocation of the individual(s) or other measures approved by the CDFW.

BIO-4 Mitigation Related to MBTA If ground disturbance, tree or plant removal is proposed between February 1st and August 31st, a qualified biologist shall conduct a nesting bird survey within 7 to 10 days of initiation of grading onsite focusing on MBTA covered species. If active nests are reported, then species-specific measures shall be prepared.

At a minimum, grading in the vicinity of a nest shall be postponed until the young birds have fledged. For construction between September 1st and January 31st, no pre-removal nesting bird survey is required.

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 35 August 2026
a. In the event active nests are found, exclusionary fencing shall be placed 200 feet around the nest until such time as nestlings have fledged. Nests of raptors and burrowing owls shall be provided a 500-foot buffer. Ground disturbance between September 1 and January 31 shall be exempt from this requirement.

BIO-5 Mitigation Related to Bats Focused surveys shall be conducted to ensure that bats are not present to avoid or minimize harm or disturbance by construction activities. Potential roost sites include, but may not be limited to, bridges associated with I-10, UPRR, and the Whitewater River Stormwater Channel, and any other structures in the project area that could provide roosts for bats.

BIO-6 Mitigation Related to Casey’s June Beetle Projects in the USFWS-designated CJB survey area shall be required to conduct preconstruction site assessments and species surveys in accordance with USFWS protocols and requirements. Should the species be detected onsite, an appropriate mitigation program shall be developed in cooperation with the project proponent, USFWS, and other appropriate parties.

BIO-7 Mitigation Related to Jurisdictional Waters and Wetlands Prior to the initiation of any construction within areas determined by a Jurisdictional Delineation to be waters of the US, a permit or permits shall be approved and issued by the USACE under Section 404 of the CWA to authorize the discharge of dredged or fill material into waters of the US.

BIO-8 Mitigation Related to Jurisdictional Waters and Wetlands Prior to the initiation of any construction within areas determined by a Jurisdictional Delineation to be waters of the US or the State, a Water Quality Certification shall be approved and issued by the Colorado River RWQCB (Region 7) under Section 401 of the CWA.

BIO-9 Mitigation Related to Jurisdictional Waters and Wetlands Prior to the initiation of any construction within areas determined by a Jurisdictional Delineation to be waters of the State, a permit or permits shall be approved and issued by the Colorado River RWQCB (Region 7) under the Porter Cologne Water Quality Control Act.

BIO-10 Mitigation Related to Jurisdictional Waters and Wetlands Prior to the initiation of any construction within areas determined by a Jurisdictional Delineation to be waters of the State, a 1602 Streambed Alteration Agreement shall be approved and issued by the California Department of Fish and Wildlife.

4.5 Cultural Resources and Tribal Cultural Resources
Summary of Analysis in the General Plan EIR
Biological resources are discussed in Section 2.6, Cultural and Tribal Cultural Resources, of the General Plan EIR. The General Plan EIR determined that the city includes several historic properties that have been recorded in the California Historical Resource Information Center (CHRIS), although some have been demolished or significantly altered. The City’s 2017 Historic Resource Context and Historic Resource Program determined that some buildings are related to the eight local historic context categories (identified in the Historic Resource Program) and retain some level of architectural integrity, and they may be eligible for inclusion in a future register. Therefore, the General Plan EIR concluded that implementation of its land use plan and various policies and programs could impact the treatment of historical resources. However, the Cultural Resources Sub-Element of the General Plan includes policies and programs intended to protect significant historic resources. Policy 1 ensures that sites in historically sensitive areas are surveyed prior to development. Programs 1.A through 1.G establish specific requirements and parameters for the identification and evaluation of archaeological and historic sites. Policy 2 seeks to protect sensitive historic resources from vandalism and illegal collection. Policy 3 encourages the Cathedral City Historical Society to establish a program to list locally significant resources, and Policy 4 encourages the public’s appreciation of historic resources. Policy 5 requires the City to consider offering owners of historical buildings and sites economic incentives for property rehabilitation and maintenance. In addition, required project-specific pre-construction surveys that identify historic resources and set forth treatment measures to minimize potential impacts (Mitigation Measures CUL-1, CUL-2 and CUL-3, described below) would reduce impacts to historic resources to a less than significant level.

As it relates to archaeological resources, the City includes known archaeological resources and areas of potential Native American cultural significance. It includes land within the Agua Caliente Band of Cahuilla Indians Reservation and the Traditional Use Area of Native Americans. Although the valley floor has low sensitivity for archaeological resources, the foothills and canyons of the Santa Rosa Mountains and mesquite dunes between Seven Palms Valley and Edom Hill, and Edom Hill itself, are highly sensitive for potential archaeological resources. Therefore, the General Plan EIR concluded that implementation of its land use plan could impact archaeological resources. However, the Cultural Resources Sub-Element of the General Plan sets forth policies and programs that provide for the longterm protection of archaeological resources. Policy 1 and Program 1.A ensure that culturally sensitive areas are surveyed prior to development and that the City coordinates with the Eastern Information Center for review and input. Program 1.E requires that, in the event that archaeological resources are identified during construction, development cease and the site be examined and documented by a professional archaeologist to examine and document the site and determine subsequent actions. Policy 2 calls for the protection of sensitive archaeological resources from vandalism and illegal collection.

Policy 3 encourages the Cathedral City Historical Society to establish a program to qualify and list locally significant resources on available state and federal registers, and Policy 4 encourages public participation and appreciation of archaeological resources. In addition, future development projects would be evaluated on a project-by-project basis to determine the presence of archaeological resources and determine their significance. Impacts of individual development projects on archaeological resources would be reduced to less than significant levels through pre-construction surveys (Mitigation Measure CUL-4, described below), impact avoidance and/or proper procurement and documentation of unearthed archaeological resources (Mitigation Measure CUL-5, described below). Lastly, should human remains be discovered in conjunction with individual development projects in the planning area, City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 37 August 2026
the provisions of California Health and Safety Code Sections 7050.5 - 7055 and Mitigation Measure CUL-6, described below, would ensure that impacts would be mitigated to less than significant levels.

Relative to Tribal Cultural Resources, the Agua Caliente Indian Reservation, belonging to the Agua Caliente Band of Cahuilla Indians (ACBCI), is partially located in the City of Cathedral City. The Reservation consists of approximately 31,500 acres generally distributed in Sections of land in a checkerboard pattern within the boundaries of Palm Springs, Cathedral City, Rancho Mirage, and unincorporated Riverside County. The City and ACBCI maintain a close and cooperative relationship to monitor and regulate the use and development of property belonging to, held, leased from, or under agreement with any Indian Allottee or the ACBCI. An archaeological rock ring feature that has been listed in the CHRIS and six locations of potential Native American cultural significance (shown on Exhibit

2.6-1 of the General Plan EIR) have been identified by anthropologists and Cahuilla cultural authorities.

Four are located along the base of the San Jacinto and Santa Rosa Mountains, one in the Whitewater River in the same general vicinity, and one near Edom Hill.

The General Plan EIR determined that site disturbances on vacant land, such as grading and subsurface excavations, may unearth previously unknown Tribal Cultural Resources during implementation of future development under the General Plan, particularly in culturally sensitive areas north of I-10. However, the Cultural Resources Sub-Element of the General Plan includes Policies 1, 2, and 4 and their respective programs, that would protect cultural resources from development, vandalism, and illegal collection, and encourage public participation in the appreciation and protection of cultural resources.

Program 4.A requires the City’s continued coordination and cooperation with the ACBCI in the protection of cultural resources, which will reduce impacts to Tribal resources. In addition, General Plan EIR Mitigation Measures CUL-4, CUL-5, and CUL-6 will assure that potential impacts of individual development projects within the City’s planning area on Tribal Cultural Resources are reduced to less than significant levels.

The City would consider the proposed Project to have a significant effect on cultural resources if it is determined that the Project will:
a) Cause a substantial adverse change in the significance of a historical resource pursuant to § 15064.5.
b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5.
c) Disturb any human remains, including those interred outside of dedicated cemeteries.

The following significant thresholds or criteria are derived from Appendix G of CEQA, which is used to determine if and to what extent a project may have a potentially significant impact on Tribal resources.

The City would consider the proposed Project to have a significant effect on Tribal resources if it is determined that the Project will:
a) Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 38 August 2026
i) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k), or ii) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same cultural and Tribal Cultural Resources impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

The Development Code Update, in and of itself, does not propose specific projects but aligns the Code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts on cultural resources such as historical or archaeological resources, Tribal Cultural Resources, or human remains.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

CUL-1 In instances where maintenance, repair, stabilization, rehabilitation, restoration, preservation, conservation or reconstruction of an historical resource will be conducted in a manner consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings (1995), the project's impact on the historical resource shall generally be considered mitigated below a level of significance and thus is not significant.

CUL-2 Where appropriate and in conjunction with other measures, require documentation of an historical resource by way of historic narrative, photographs or architectural drawings, prior to impacting the resource, and require additional mitigation where necessary to City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 39 August 2026
ensure that adequately mitigate the effects to a point where impacts are clearly less than significant.

CUL-3 Whenever feasible, seek to avoid damaging effects on any historical resource of an archaeological nature. The following factors shall be considered and discussed in CEQA documentation for a project involving such an archaeological site:
(A) Preservation in place shall be the preferred manner of mitigating impacts to archaeological sites. Preservation in place maintains the relationship between artifacts and the archaeological context. Preservation may also avoid conflict with religious or cultural values of groups associated with the site. (B) Preservation in place may be accomplished by, but is not limited to, the following:

1. Planning construction to avoid archaeological sites;

2. Incorporation of sites within parks, greenspace, or other open space;

3. Covering the archaeological sites with a layer of chemically stable soil before building tennis courts, parking lots, or similar facilities on the site.

4. Deeding the site into a permanent conservation easement. (C) When data recovery through excavation is the only feasible mitigation, a data recovery plan, which makes provision for adequately recovering the scientifically consequential information from and about the historical resource, shall be prepared and adopted prior to any excavation being undertaken. Such studies shall be deposited with the California Historical Resources Regional Information Center. Archaeological sites known to contain human remains shall be treated in accordance with the provisions of Section 7050.5 Health and Safety Code. If an artifact must be removed during project excavation or testing, curation may be an appropriate mitigation.
(D) Data recovery may not necessarily be required for an historical resource if the City, as CEQA lead agency determines that testing or studies already completed have adequately recovered the scientifically consequential information from and about the archaeological or historical resource, provided that the determination is documented in the project EIR and that the studies are deposited with the California Historical Resources Regional Information Center.

CUL-4 Pre-Construction Surveys The City shall require intensive-level cultural resources surveys by qualified archaeologists, historians, and/or architectural historians, where deemed necessary and especially in areas of high sensitivity for cultural resources, as shown on Exhibit 2.6-1 [of the General Plan EIR]. Studies should include in-depth records search at the EIC, historic background research, intensive-level field survey, and consultation with the Cathedral City Historical Society, Native American representatives, and/or other relevant parties, as well as impact evaluation and mitigation programs, as needed. The City shall monitor and enforce recommended mitigation measures.

CUL-5 Archaeological and/or Tribal Resource Procurement and Documentation Should unknown archeological or tribal cultural resource materials become unearthed, the area of potential resources shall be cordoned off and protected from further disturbance until a qualified archeologist can investigate the discovery. The qualified archaeologist shall City of Cathedral City

The submittal of the report to the City and Tribal representative, as appropriate, along with final curation of the recovered artifacts, will signify completion of the monitoring program and, barring unexpected findings of extraordinary significance, the mitigation of potential project impacts on cultural and Tribal resources.

CUL-6 Human Remains Should buried human remains be discovered during grading or other construction activity, in accordance with State law, the County coroner shall be contacted. If the remains are determined to be of Native American heritage, the Native American Heritage Commission and the appropriate local Native American Tribe shall be contacted to determine the Most Likely Descendant (MLD).

4.6 Energy and Mineral Resources
Summary of Analysis in the General Plan EIR
Energy
Energy resources are discussed in Section 2.7, Mineral and Energy Resources, of the General Plan EIR. The General Plan EIR determined that while implementation of projects proposed under the General Plan would increase overall demand for electricity, natural gas, and transportation fuel at buildout, this increase would not result in wasteful, inefficient, or unnecessary consumption of energy resources. Table 4, General Plan EIR Energy Consumption displays the energy consumption (electricity, natural gas, and vehicle fuel demand) associated with the existing and proposed General Plan. The proposed General Plan Land Use Plan would result in modest increases in electricity demand (total consumption of approximately 697 million kWh/year at buildout) and natural gas demand (total consumption of approximately 16.1 million therms/year at buildout) compared to the existing land use plan. However, increased land use efficiencies under the proposed General Plan would reduce overall vehicle miles traveled (VMT) at buildout, resulting in a slight reduction in annual transportation fuel consumption compared to the existing land use plan.

Table 4: General Plan EIR Energy Consumption

Notes: kWh = kilowatt-hour

1. Annual energy consumption is from Table 2.7-3 through 2.7-5 of General Plan EIR.

2. Numbers within parentheses represent a net decrease from existing conditions.

The General Plan EIR found that implementation of Policies 1 through 6 of the Energy and Mineral Resources Element would encourage energy conservation, promote use of local renewable resources including wind and solar, and minimize VMT through efficient land use patterns and circulation system design. Future development projects would be evaluated on a project-by-project basis to ensure compliance with applicable energy-related regulations, including the California Building Code and California Green Building Code. Additionally, the General Plan EIR determined that implementation of Mitigation Measures ME-1 through ME-6, as described below in “Applicable General Plan EIR Mitigation Measures,” would ensure that energy impacts associated with the implementation of the General Plan are reduced to less than significant.

The General Plan's Energy and Mineral Resources Element policies actively support energy conservation, participation in regional renewable energy efforts, and exploration of policies to increase energy efficiency. Future development facilitated by the General Plan would be required to comply with all applicable state and local energy standards on a project-by-project basis. The General Plan EIR determined that the General Plan would not interfere or conflicts with any state or local renewable energy or energy efficiency plans and thus, no impact would occur.

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 42 August 2026
Mineral Resources
Mineral resources are discussed in Section 2.7, Mineral and Energy Resources, of the General Plan EIR. The General Plan EIR determined that the planning area contains no known mineral resources and future development projects facilitated under the General Plan would not result in the loss of availability of a known resource of value to the region or to the residents of the state. According to the California Department of Conservation, the planning area is designated as Mineral Resource Zone 3 (MRZ-3) which contains known or inferred mineral occurrences of undetermined mineral resource significance.

However, the General Plan EIR states that land within the city is not designated for mineral resources and no mineral resource recovery sites are delineated on the General Plan.

According to the General Plan EIR, the nearest mapped mineral resource zone is located in Indio Hills near the community of Thousand Palms. However, this mineral resource zone is located outside the City’s sphere of influence (SOI). Additionally, future development and redevelopment facilitated by the General Plan would increase the demand for sand and gravel resources, however, these resources would be derived from the regional Coachella Valley market. The demands associated with the buildout of the General Plan are not considered significant when compared to available regional resources.

The General Plan EIR determined that adherence to Goal 1 of the Energy and Mineral Resources Element of the General Plan and its associated policies would minimize potential impacts to mineral resources. Impacts were determined to be less than significant.

The City would consider the proposed Project to have a significant effect on energy resources if it is determined that the project will:
a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation. b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency.

Additionally, the City would consider the proposed Project to have a significant effect on mineral resources if it is determined that the project will:
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.

Proposed Project Analysis
Energy Resources
The proposed Project would update the Development Code for consistency with the 2040 General Plan.

The update would result in the creation of new zoning districts as well as the elimination of existing districts; the renaming of existing districts; the consolidation of existing districts; as well as the modification or modernization of requirements for development and land uses within various other districts. However, these districts and their standards would be consistent with the 2040 General Plan.

The proposed Project would update but not eliminate the fundamental regulations and requirements of City of Cathedral City

the Development Code, such as meeting design and development standards. The proposed Project would align the Development Code with the General Plan and ensure it regulates the types of land uses and development envisioned in the General Plan.

The proposed Project would implement the 2040 General Plan and thus would result in the same energy demand from new development and redevelopment as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan. The proposed Project would not introduce land uses beyond those previously analyzed in the General Plan EIR. Accordingly, the assumptions underlying electricity, natural gas, and vehicle fuel demand projections established in the General Plan EIR would remain unchanged.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations, including applicable energy efficiency standards such as the California Building Code and California Green Building Code. Furthermore, compliance with Mitigation Measures ME-1 through ME-6 would ensure energy efficiency is promoted at the project, local agency, and city levels. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Mineral Resources
The proposed Project would implement the 2040 General Plan, thereby resulting in the same mineral resources impacts from new development as evaluated in the certified General Plan EIR. The planning area is designated MRZ-3 by the California Department of Conservation, reflecting an area where development has limited the ability to determine the presence or amount of mineral resources. No known mineral resources exist within the city or its sphere of influence, and no locally important mineral resource recovery sites are delineated on any applicable land use plan. Additionally, the proposed Project would not expand the existing planning area into areas with existing mineral extraction. Lastly, the proposed Project would not designate any land for mineral production or convert any mineral resource land to a different land use.

The Development Code Update, in and of itself, does not propose specific projects but aligns the zoning code to match the General Plan. As such, the Development Code Update would not directly or indirectly result in the loss of availability of a known mineral resource or a locally important mineral resource recovery site. Future development facilitated by the Development Code Update would undergo projectspecific developmental review and would be subject to adopted development regulations, including adherence to Goal 1 of the Energy and Mineral Resources Element and its associated policies.

Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

ME-1 The City shall require new developments to reduce energy consumption through appropriate building technologies, promotion of non-auto transportation modes, support for greater use of alternative energy sources, and dissemination of public information regarding energy conservation techniques.

ME-2 The City shall work with utility providers to provide incentives for energy- and waterefficient building projects, e.g. by giving green projects priority in plan review, processing, and field inspection services.

ME-3 The City shall develop or otherwise make available information to developers on energy efficient and conserving building design and technologies, addressing enhanced wall and ceiling insulation, thermally efficient glazing, and efficient heating and cooling equipment and household appliances.

ME-4 The City shall periodically assess the local transportation system and plan or maintain improvements that enhance the efficient movement of people and goods through the community.

ME-5 The City shall continue to participate in the transportation planning efforts of SunLine Transit Authority and shall encourage the expanded use of public transit, vehicles fueled by compressed natural gas and hydrogen, buses with bike racks and other system improvements that enhance overall transportation system operations and energy conservation.

4.7 Geology and Soils
Summary of Analysis in the General Plan EIR
Geology and soils are discussed in Section 2.8, Geology and Soils, of the General Plan EIR. The General Plan EIR determined that future development facilitated by the General Plan be exposed to seismic hazards including fault rupture, ground shaking, ground failure, or landslide from the San Andreas (Coachella segment), Garnet, or San Jacinto Faults. These earthquake faults pose surface rupture hazards to developments proposed over the fault traces and ground shaking hazards due to regional earthquake events could lead to the damage of buildings, parking lots, and utility lines, and resulting fires, falling objects, and other structural hazards, which could cause property damage and personal injuries. Ground-shaking hazards are not unlike the potential hazards in other areas of the region. However, compliance with the Alquist-Priolo Act would minimize surface rupture hazards to new development and redevelopment in the planning area. In addition, General Plan EIR Mitigation Measures GEO-1 through GEO-5 include both site-specific requirements for future development under the General Plan and recommended City actions, which would reduce seismic hazard impacts to less than significant.

Future development and redevelopment pursuant to the General Plan would involve grading and excavation activities on individual sites, which would result in changes to the area’s existing geology and soils conditions. Development sites that are relatively flat would remain flat, while hillside development would require cut and fill, manufactured slopes, and changes to the natural topography.

Future development and redevelopment in the city’s planning area would be designed and built in accordance with applicable standards in the California Building Code (CBC), including pertinent seismic design criteria. Existing buildings would be rehabilitated in accordance with the CBC and local building regulations. This will allow structures to withstand ground shaking and to maintain hazards at acceptable levels. Site-specific geologic hazards would be addressed by geotechnical investigations required by the City for each future development proposal. Investigations would identify the geologic and seismic characteristics of a site and provide guidelines for engineering design and construction to ensure the structural integrity of the proposed development. Compliance of individual projects with the recommendations of the geotechnical investigation would prevent potential hazards associated with unstable soils, landslides, lateral spreading, liquefaction, soil collapse, expansive soil, soil erosion, and other geologic issues. In addition, General Plan EIR Mitigation Measures GEO-5 through GEO-20 include both site-specific requirements for future development under the General Plan and recommended City actions, which would reduce impacts relative to soil erosion, unstable geologic units/soils, landslide, lateral spreading, subsidence, liquefaction or collapse, and expansive soils, to less than significant.

Relative to septic tanks and/or alternative wastewater disposal systems, the City passed Ordinance 572 in 2000 to prohibit issuance of permits for new septic tank installation within the City. All new and existing buildings and structures with plumbing facilities are required to be connected to an available public sewer system. The ordinance included provisions to fine people that did not connect to the sewer system. Additionally, Ordinance 626 (passed in 2006) states that, where developers install sewer improvements that subsequently benefit other properties located between the sewer improvements and the point of connection to an existing main, they shall be eligible to enter into a reimbursement agreement with the City. Therefore, the General Plan EIR concluded that the General Plan would not violate or alter City ordinances pertaining to sewer system connections. The General Plan would facilitate new development in the planning area. Where existing sewer lines are available, development would connect to the public sewer system (Policy 5 - Water Resources Element). Where no sewer lines City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 46 August 2026
are present, the public sewer system would need to be expanded to serve development. No mitigation measures were identified in the General Plan EIR for this impact and compliance with City standards would ensure that impacts relative to septic tanks and/or alternative wastewater disposal systems remain less than significant.

As it pertains to unique paleontological or geologic features, the city is not known to contain unique paleontological or geologic features. The majority of city soils are composed of recently deposited alluvium which has a low potential to contain paleontological resources. The planning area is largely developed south of I-10, and the urban landscape is a mix of residential, commercial, industrial, and other development, as well as roadways, utilities, and other infrastructure. Any paleontological or geologic sites or resources would likely have been disturbed already by urban development. Land north of I-10 is generally undeveloped and could harbor unknown resources.

The General Plan Land Use Plan would allow for development and redevelopment in the planning area that could result in direct and/or indirect impacts to paleontological and geologic resources. Grounddisturbing activities could have the potential to damage or destroy paleontological resources that may be present below the ground surface. Any future projects that would be allowed under the General Plan would be subject to CEQA analysis on a project-by-project basis to identify potential impacts and establish appropriate mitigation measures, as needed. Overall, the General Plan EIR concluded that impacts would be less than significant, and no mitigation is required.

The City would consider the proposed Project to have a significant effect on geology and soils if it is determined that the Project will:
a) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving:
i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault. Refer to Division of Mines and Geology Special Publication

42. ii) Strong seismic ground shaking.
iii) Seismic-related ground failure, including liquefaction. iv) Landslides.
b) Result in substantial soil erosion or the loss of topsoil. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on-or off-site landslide, lateral spreading, subsidence, liquefaction or collapse.
d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property. e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water. f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature.

EIR Addendum PAGE 47 August 2026
Proposed Project Analysis
Policies and actions in the General Plan that were referenced in the General Plan EIR would reduce impacts to the greatest extent possible. These policies and actions would continue to be required with implementation of the Development Code Update. The proposed Project would update the Development Code for consistency with the 2040 General Plan. The update would result in the creation of new zoning districts as well as the elimination of existing districts; the renaming of existing districts; the consolidation of existing districts; as well as the modification or modernization of requirements for development and land uses within various other districts. However, these districts and their standards would be consistent with the 2040 General Plan. The proposed Project would update but not eliminate the fundamental regulations and requirements of the Development Code, such as meeting design and development standards. The proposed Project would align the Development Code with the General Plan and ensure it regulates the types of land uses and development envisioned in the General Plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same geology and soils impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

The Development Code Update, in and of itself, does not propose specific projects but aligns the Code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts to geology and soils such as causing potential adverse effects involving fault rupture, ground shaking, liquefaction, and landslides, nor would the update result in loss of topsoil, cause a geologic unit to become unstable, be located on soils incapable of supporting septic tank use, or destroy a unique paleontological resource.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

GEO-1 The City shall establish and maintain an information database containing maps and other information which describe seismic and other geotechnical hazards occurring within the planning area.

GEO-2 The City shall actively promote public education, research, and information dissemination on seismic and geotechnical hazards.

GEO-3 New development in the planning area shall be constructed in accordance with the prevailing seismic design requirements contained in the most recently adopted edition of the Uniform Building Code/International Building Code and as otherwise required by the City.

GEO-4 The City shall continue to incorporate seismic risk analysis into the City's on-going building inspection program.

GEO-5 On sites where threats from seismic hazards cannot be adequately mitigated through the application of existing regulatory requirements and Updated General Plan policies and implementation programs, the City shall use open space easements and/or other related regulatory measures to limit development and thus avoid public safety hazards.

EIR Addendum PAGE 48 August 2026
GEO-6 Proposals for development on wind or stream-deposited sediment on the valley floor shall include site-specific subsurface geotechnical investigations that address settlement, liquefaction, and collapsible soils. These hazards can generally be mitigated by proper excavation, compaction and foundation design.

GEO-7 The City shall continue to require expansive soils testing as part of its grading and building codes, and shall assure the implementation of mitigation measures which minimize these hazards, such as the use of reinforcing steel in foundations, drainage control devices, overexcavation and backfilling with non-expansive soils.

GEO-8 The City shall continue to support and encourage local and regional groundwater conservation measures in an effort to mitigate potential subsidence resulting from groundwater overdraft. (see also Water Resources discussion in Section 2.10, Hydrology and Water Quality [of the General Plan EIR]).

GEO-9 All grading permit requests shall include a PM10 Management Plan in conformance with the latest approved Coachella Valley PM10 requirements in place at the time construction occurs. Blowing dust and sand during grading operations shall be mitigated by adequate watering of soils prior to and during grading, and limiting the area of dry, exposed soils during grading (see also Air Quality discussion in Section 2.4 [of the General Plan EIR]).

GEO-10 Where development is proposed adjacent to or in close proximity to steep slopes, sitespecific geotechnical studies shall be conducted to evaluate the potential for rock falls and/or slope failure, and to establish mitigation measures which minimize these hazards.

GEO-11 All development proposed within Alquist-Priolo Earthquake Zones and City-designated study zones shall comply with State requirements for site-specific study, including trenching to locate fault traces, and to submit this analysis prior to any development approval for the property.

GEO-12 During site grading, all existing vegetation and debris shall be removed from areas that are to receive compacted fill. Any trees to be removed shall have a minimum of 95% of the root systems extracted or as prescribed by the project soils engineer. Man-made objects shall be overexcavated and exported from the site. Removal of unsuitable materials may require excavation to depths ranging from 2 to 4 feet or more below the existing site grade.

GEO-13 All fill soil, whether on site or imported, shall be approved by the individual project soils engineer prior to placement as compaction fill. All fill soil should be free from vegetation, organic material, cobbles and boulders greater than 6 inches in diameter, and other debris. Approved soil shall be placed in horizontal lifts of appropriate thickness, as prescribed by the soils engineer, and watered or aerated as necessary to obtain nearoptimum moisture content.

GEO-14 Fill materials shall be completely and uniformly compacted to not less than 90% of the laboratory maximum density as determined by ASTM test method D-1557-78. The project soils engineer shall observe the placement of fill and take sufficient tests to verify the moisture content, uniformity, and degree of compaction obtained. In-place soil density should be determined by the sand-cone method, in accordance with ASTM Test Method D-1556-64 (74), or equivalent test method recommended by the soils engineer and as acceptable to the City Building and Safety Department.

GEO-15 Finish cut slopes generally shall not be inclined steeper than 2:1 (horizontal to vertical).

Attempts to excavate near-vertical temporary cuts for retaining walls or utility installations in excess of 5 feet may result in gross failure of the cut and may possibly damage equipment and injure workers. All cut slopes must be inspected during grading to provide additional recommendations for safe construction.

GEO-16 Finish fill slopes shall not be inclined steeper than 2:1 (horizontal to vertical) or as approved by the project geotechnical engineer. Fill slope surfaces should be compacted to 90% of the laboratory maximum density by either over-filling and cutting back to expose a compacted core or by approved mechanical methods.

GEO-17 Foundation systems that utilize continuous and spread footings are recommended by the project soils engineer for the support of one and two-story structures. Foundations for higher structures must be evaluated based on structure design and on-site soil conditions.

GEO-18 Positive site drainage shall be established during finish grading. Finish lot grading shall include a minimum positive gradient of 2% away from structures for a minimum distance of three (3) feet and a minimum gradient of 1% to the street or other approved drainage course.

GEO-19 An adequate subdrain system shall be constructed behind and at the base of all retaining walls to allow for adequate drainage and to prevent excessive hydrostatic pressure.

GEO-20 Utility trench excavations in slope areas or within the zone of influence of structures should be properly backfilled in accordance with the following recommendations:
a) Pipes shall be bedded with a minimum of 6 inches of pea gravel or approved granular soil. Similar material shall be used to provide a cover of at least 1 foot over the pipe. This backfill shall then be uniformly compacted by mechanical means or jetted to a firm and unyielding condition.
b) Remaining backfill may be fine-grained soil. It shall be placed in lifts not exceeding 6 inches in thickness or as determined appropriate, watered or aerated to near optimum moisture content, and mechanically compacted to a minimum of 90% of the laboratory maximum density.
c) Pipes in trenches within 5 feet of the top of slopes or on the face of slopes shall be bedded and backfilled with pea gravel or approved granular soils as described above. The remainder of the trench backfill shall comprise typical on-site fill soil mechanically compacted as described in the previous paragraph.

4.8 Hazards, Hazardous Materials and Wildfires
Summary of Analysis in the General Plan EIR
Hazards, hazardous materials and wildfires are discussed in Section 2.9, Hazards, Hazardous Materials and Wildfires, of the General Plan EIR. The General Plan EIR determined that in the Coachella Valley, the potential for exposure to hazards and hazardous materials exists due to the presence of commercial uses, past and present agricultural activity, industrial operations, transportation and distribution of products, and use of hazardous materials by households and businesses. Major transportation corridors in the valley that facilitate transportation of hazardous materials include I-10, SR-74, SR-86, SR-62, State Highway 111, and the Union Pacific Railroad. Proximity to the Palm Springs International Airport, Bermuda Dunes Airport, and Jacqueline Cochran Regional Airport may also result in safety hazards. In addition, several sites in the valley are identified on the State Water Resources Control Board (SWRCB) and Department of Toxic Substances Control (DTSC) contaminated site lists. They generally include commercial businesses, such as gas stations, with fuel or oil leaks or spills; cleanup efforts are monitored by the appropriate agencies.

Relative to airport hazards, the General Plan EIR concluded that future development as a result of the adoption of the General Plan will be in compliance with regulations established by the State Department of Health Services and the Riverside County Airport Land Use Compatibility Plan (ALUCP), and policies and implementing actions found in the 2040 General Plan. The General Plan EIR did not identify applicable any mitigation measures regarding airport hazards and airport hazards are not discussed further.

Relative to wildfire hazards, the General Plan EIR identified that a small southwestern portion and an equally small area in the southeast in the vicinity of East Palm Canyon are designated by CALFIRE as a very high fire hazard severity zone (VHFHS) fire hazard zone within the Local Responsibility Area and State or Federal Responsibility Area, the State of California. No wildland fires have occurred within the City’s planning area. The City coordinates with CALFIRE on refinements to current fire hazard mapping in the City. Therefore, the General Plan EIR did not identify applicable any mitigation measures regarding wildfires due to the overall lack of wildfire hazards in the city’s planning area and wildfire hazards are not discussed further.

As it pertains to hazardous materials and based on the General Plan EIR, future development pursuant to the General Plan may utilize or generate hazardous materials or wastes; however, they are not expected to occur in quantities that would pose a significant hazard to the public or the environment.

The General Plan land use map does not include heavy industry or other land uses that would generate or use large quantities of hazardous materials. Existing regulations provide guidelines to users to prevent potential risks associated with hazardous materials. Compliance with existing hazardous material regulations would prevent undue hazards. The Hazards and Hazardous Materials Sub-Element of the General Plan includes goals, policies, and programs that promote a safe community and environment for its residents. The City is directed to utilize Riverside County’s and the Regional Water Quality Control Board’s (RWQCB) available resources to update data about contaminated sites and facilitate the adequate and timely cleanup of existing and future contaminated sites within the City and its sphere-of-influence (Policies 1 and 2). Policy 4 requires the City to designate appropriate access routes to facilitate the transport of hazardous and toxic materials and wastes. Policy 11 ensures sufficient distance of hazardous facilities and schools, hospitals, residential areas, and other sensitive receptors to minimize exposure to hazardous materials. Policies 12 through 15 require the City to discourage use of large quantities of hazardous materials and hazardous fuels in the planning area and City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 51 August 2026
to engage the community in programs to reduce and recycle hazardous materials, and to oversee remediation of toxic sites.

In addition, required project-specific mitigation measures to minimize potential impacts (Mitigation Measures HAZ-1 through HAZ-3, described below) would reduce impacts regarding hazards and hazardous materials to a less than significant level. Mitigation Measure HAZ-1 would require future development projects that propose to use large quantities of hazardous materials are reviewed by the City prior to issuance of building permits, for compatibility with existing and planned land uses, focusing on the location of existing and planned sensitive receptors (e.g., residential uses, schools, etc.) and for a determination whether the proposed usage would expose these sensitive receptors to unacceptable safety risks. Mitigation Measure HAZ-2 requires that the siting of industrial facilities which involve storage of hazardous, flammable or explosive materials be conducted in a manner that will ensure the highest level of safety in strict conformance with the Uniform Fire Code, California Fire Code and other applicable regulations. Mitigation Measure HAZ-3 requires that new and substantially renovated development at or near the slopes of the Santa Rosa Mountains or the Indio Hills be thoroughly reviewed for potential exposure to a wildfire risk, and also be assessed for the potential of urban development in these areas to facilitate the spread of a wildfire into other developed portions of the community.

Additionally, the General Plan EIR includes Mitigation Measures HAZ-4, HAZ-5 and HAZ-6, which identify actions that the City is responsible for to reduce these impacts, such as periodic review and update the Local Hazard Mitigation Plan and the Emergency Operations Plan; evaluation of the full range of physical and other constraints to the effective implementation of the Emergency Operations Plan; and the provision of information to residents to plant and maintain drought-resistant, fire-retardant landscape species to reduce the risk of brush fire and soil erosion in areas adjacent to canyons and stringent site design and maintenance standards for areas with high fire hazard or soil erosion potential.

Therefore, the General Plan EIR concluded that implementation of the above will assure that potential impacts of individual development projects within the city’s planning area relative to hazards, hazardous materials and wildfires are reduced to less than significant levels.

Thresholds of Significance
The following significant thresholds or criteria are derived from Appendix G of CEQA, which is used to determine if and to what extent a project may have a potentially significant impact relative to hazards and hazardous materials. The City would consider the proposed Project to have a significant effect regarding hazards and hazardous materials if it is determined that the Project will:
a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials.
b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment.
e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area.

f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan.
g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires.

The City would consider the proposed Project to have a significant effect regarding wildfires if it is determined that the project will:
a) Substantially impair an adopted emergency response plan or emergency evacuation plan. b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire.
c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment. d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same hazards, hazardous materials and wildfire impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

HAZ-1 Prior to issuance of building permits for any new development or substantial redevelopment within the planning area that proposes to use large quantities of hazardous materials, the City shall review the project application for compatibility with existing and planned land uses. The review process shall focus on the location of existing and planned sensitive receptors (e.g., residential uses, schools, etc.) and determine whether the proposed usage would expose these sensitive receptors to unacceptable safety risks. If necessary, the City shall condition the proposed hazardous materials user to incorporate appropriate protection measures.

4.9 Hydrology and Water Quality
Summary of Analysis in the General Plan EIR
Hydrology and water quality are discussed in Section 2.10, Hydrology and Water Quality, of the General Plan EIR. The General Plan EIR determined that future development and redevelopment pursuant to the General Plan would increase stormwater runoff and increases in impervious surfaces in the form of structures, roads, roofs, concrete or asphalt sidewalks, parking lots, and areas of compacted soil which would increase runoff with possible petroleum and other contaminants. However, General Plan Policies 1, 2, 3, 4, 5, 6, 7, 8, and 14 of the Flooding and Hydrology Sub-Element require the City to protect groundwater from a wide variety of potential threats, including on-lot septic tanks and hazardous materials spills. They also require new development and major redevelopment projects to prepare individual Water Quality Management Plans (WQMPs) that identify (1) the potential pollutants of concern that would be generated by the project and (2) the site and hydrologic conditions of concern at downstream locations. WQMPs will identify permanent site design, source control, and treatment control BMPs that would be implemented as part of the project, including maintenance responsibilities and funding sources, and would be signed as a notarized agreement between the City and the property owner to provide a long-term commitment to its implementation. Preparation and implementation of a WQMP for new development and redevelopment projects satisfies MS4 Permit requirements and allows the City to comply with the water quality standards for storm water runoff. Policy 6 of the Flooding and Hydrology Sub-Element requires new development to provide runoff control and onsite stormwater retention, where appropriate, and Policy 9 of the Water Resources Sub-Element requires new development to maximize stormwater filtration and/or infiltration by maximizing the natural drainage patterns. In addition, Policies 10 and 11 of the Water Resources Sub-Element require new development to protect the quality of water bodies and natural drainage systems through site design, source controls, storm water treatment, runoff reduction measures, BMPs, and by minimizing the impervious surfaces and stormwater runoff.

The General Plan also includes several policies and programs that address continued protection from stormwater exceedances and pollution. Program 1.A of the Flooding and Hydrology Sub-Element requires the City to establish local regulations and guidelines to direct the management of runoff and provide for local drainage facilities to minimize surface runoff. Future development facilitated by the General Plan would be evaluated on a case-by-case basis to assure potential impacts related to stormwater drainage and pollution are precluded. Standard requirements already in place address onsite retention basins, offsite drainage facilities and permits to minimize surface runoff. In addition, General Plan EIR Mitigation Measures HYD-1 through HYD-17 include both site-specific requirements for future development under the General Plan and recommended City actions, which would reduce these hydrology and water quality impacts to less than significant.

Relative to flooding, the General Plan EIR concluded that future development and redevelopment pursuant to the General Plan would potentially expose human lives and property to a variety of flooding hazards. However, General Plan policies and programs serve to avoid, minimize and mitigate these potential hazards. Emergency Preparedness Sub-Element Policy 1 requires maintaining and regularly updating the City’s Local Hazard Mitigation Plan as an integrated component of the General Plan, in coordination with Riverside County and other participating jurisdictions, to maintain eligibility for maximum grant funding. Policy 4 requires the City to coordinate with the Federal Emergency Management Agency (FEMA), state agencies, Riverside County, and other jurisdictions to update Flood Insurance Rate Maps for the city. Policy 6 of this element requires all new development to incorporate adequate flood mitigation measures, such as grading that prevents adverse drainage impacts to City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 55 August 2026
adjacent properties, on-site retention of runoff, and the siting and sizing of adequate structures located within flood plains. Policy 9 prohibits the construction of critical health and safety facilities within the 100- year flood plain unless flood-proofing or other mitigation measures are implemented. Policy 10 requires flood-prone areas to be considered inappropriate for conventional urban development without appropriate flood control facilities. Program 1.A of the Flooding and Hydrology Sub-Element requires the City to establish local regulations and guidelines to direct the management of runoff and provide for local drainage facilities to minimize surface runoff. In addition, General Plan EIR Mitigation Measures HYD-4 through HYD-8 include both site-specific requirements for future development under the General Plan and recommended City actions, which would reduce these flood-related impacts to less than significant.

Relative to water resources and groundwater supplies, the City of Cathedral City obtains water services from the Coachella Valley Water District (CVWD) and Desert Water Authority (DWA), whose main water supply comes from the underlying Whitewater Groundwater Basin. Future development and redevelopment would increase the long-term demand for water for domestic purposes and landscape irrigation. This increased water demand may lead to an increase in groundwater pumping from local wells. However, the CVWD and DWA regulate groundwater pumping from the Whitewater Groundwater Basin, and comply with pumping rights, as required under the Sustainable Groundwater Management Act (SGMA). Thus, groundwater pumping that may lead to the depletion of local groundwater resources is not expected to occur. Goal 1 in the Water Resources Sub-Element of the General Plan calls for adequate, reliable, and sustainable water supplies to the community. Supporting policies direct the City to consult with the CVWD and DWA on water conservation throughout the community, including the use of drought-tolerant landscaping and low water-demanding appliances. They also direct the City to encourage the expanded use of recycled and reclaimed water, and the elimination of on-lot septic tanks to the greatest extent practicable. Promotion of water conservation by the City, in coordination with CVWD and DWA, is also mandated. In addition, General Plan EIR Mitigation Measures HYD-9 through HYD-13 include both site-specific requirements for future development under the General Plan and recommended City actions, which would reduce these groundwater and water resources impacts to less than significant.

EIR Addendum PAGE 56 August 2026
iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or
iv) impede or redirect flood flows.
d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation. e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same hydrology and water quality impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

The Development Code Update, in and of itself, does not propose specific projects but aligns the Code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts relative to hydrology and water quality such as resulting in a violation of water quality standards, decreased groundwater supplies or groundwater recharge, altered drainage patterns resulting in increased flooding, tsunami, or seiche hazard risks, or conflict with a water quality control plan.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

HYD-1 The City shall continue to partner with and support federal, State, and local agencies in regional planning and management initiatives to promote and enhance water quality in the Whitewater watershed. The City shall also participate in efforts to reduce storm water and urban runoff impacts to water quality, restoration efforts, and regional mitigation, monitoring, and public education programs.

HYD-2 The City shall require all new development to minimize the creation of new impervious to the maximum extent practicable. The City shall also prohibit post-project peak storm City of Cathedral City

4.10 Land Use and Planning
Summary of Analysis in the General Plan EIR
Land use and planning impacts are discussed in Section 2.11, Land Use and Planning, of the General Plan EIR. As it relates to the physical divide of an established community, the General Plan EIR determined that none of the proposed land use, goals, policies, and programs under the proposed General Plan Update would physically divide an established community. Instead, the General Plan Update would provide additional opportunities to create mixed-use and transit-oriented neighborhoods on vacant land. Additionally, no new roadways or neighborhood-dividing development would be facilitated by the General Plan Update. The General Plan Update includes goals and policies (Land Use Element Goal 1 and 2 and Policy 1 through 3) which promotes balanced and integrated pattern of land use. With implementation of goals and policies, the General Plan EIR determined that implementation of the General Plan Update would have a less than significant impact.

The General Plan EIR determined that the City is within jurisdiction of various land use plans, policies, and regulations such as the Santa Rosa and San Jacinto Mountains National Monument (National Monument), Coachella Valley Multiple Species Habitat Conservation, Palm Springs International Airport master plan, and the influence of Agua Caliente Band of Cahuilla Indian Tribal land. The proposed General Plan Update was determined to not conflict with these plans and would conform with applicable land use guidelines outlined in these plans and policies. Additionally, the General Plan Update was developed in conformance with the State General Plan Guidelines. As such, the General Plan EIR determined that implementation of the General Plan Update would have a less than significant impact.

While the General Plan Update would not physically divide an establish community and would not conflict with applicable plans and policies, the General Plan EIR identify Mitigation Measure LU-1, as described below in “Applicable General Plan EIR Mitigation,” which assures that potential changes in land use are adequately assessed. With implementation of Mitigation Measure LU-1, the General Plan EIR determined that implementation of the General Plan Update would have a less than significant impact on land use and planning.

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 60 August 2026
with the 2040 General Plan. The proposed Project would update but not eliminate the fundamental regulations and requirements of the Development Code, such as meeting design and development standards. The proposed Project would align the Development Code with the General Plan and ensure it regulates the types of land uses and development envisioned in the General Plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same land use and planning impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

LU-1 Individual proposed projects, especially those involving a mix of residential and other uses, as well as those located nearby or adjacent to sensitive lands or uses, shall be fully evaluated during the project review process to assure that all land use compatibility issues are addressed and mitigated.

4.11 Noise
Summary of Analysis in the General Plan EIR
Noise and vibration impacts are discussed in Section 2.12, Noise, of the General Plan EIR. As it relates to exterior noise levels, the General Plan EIR determined that future transportation noise would expose future noise-sensitive land to exterior noise levels greater than the normally acceptable exterior noise criteria. However, the General Plan EIR determined that noise management policies and programs in the General Plan and Mitigation Measures N-1 through N-11, as described below in “Applicable General Plan EIR Mitigation,” would reduce exterior transportation noise level.

As it relates to interior noise, the General Plan EIR determined that exterior noise levels along City transportation corridors have the potential to exceed 70 A-weighted decibel (dBA) Community Noise Equivalent Level (CNEL) and thus, standard building construction providing the minimum 25 dBA exterior-to-interior noise reduction may still result in interior noise levels exceeding the 45 dBA CNEL standard for residential units. As such, interior noise mitigation, as described below in “Applicable General Plan EIR Mitigation,” would be required for certain developments. With implementation of applicable policies and programs contained in the Noise Sub-Element and applicable mitigation measures, transportation noise impacts on interior noise levels were determined to be less than significant.

As it relates to long-term traffic noise from automobiles, trucks, buses, and motorcycles, the General Plan EIR determined that the buildout of the General Plan would generate traffic noise changes ranging from a decrease of 0.7 to an increase of 0.6 dBA CNEL along roadways. The noise level increases would not exceed applicable thresholds and the General Plan EIR determined that impacts were less than significant.

As it relates to vibration, the General Plan EIR determined that the noise-sensitive and non-noisesensitive uses within 50 to 150 feet of the Union Pacific Railroad (UPRR) may experience vibration levels that exceed the noise-sensitive threshold of 72 vibration decibel (Vdb) and non-noise-sensitive threshold of 75 Vdb. Thus, the policies and programs from the Noise Sub-Element, including Program

1.D, identifies and discusses the applicability of feasible measures to satisfy the 72 Vdb threshold for noise-sensitive uses. Additionally, the General Plan EIR identify Mitigation Measure N-4, as described below in “Applicable General Plan EIR Mitigation,” which would reduce and mitigate potential vibration impacts. Upon adherence to applicable policies and programs in the Noise Sub-Element and implementation of Mitigation Measure N-4, the General Plan EIR determined that implementation and buildout of the General Plan would have a less than significant impact.

The General Plan EIR determined that the 60 dBA CNEL contours of the Palm Springs International Airport (PSP) in the year of 2002 partially overlaps with the City boundaries east of San Joaquin Drive and north of Ramon Road. Furthermore, mapping of future noise conditions in the year of 2025 indicates that the 60 dBA CNEL contours of the PSP would shift to partially overlap with City boundaries east of San Joaquin Drive and north of Mission Drive. As such, the General Plan EIR determined that future (2025) noise associated with aircraft flyover events would be equal or less than existing conditions (2002). Nevertheless, the General Plan EIR determined that new or expanded school sites within two miles of PSP’s runway would be subject to review by the California Department of Transportation (Caltrans) Division of Aeronautics. Additionally, the PSP land use policies require noise reduction design features in residential dwelling units near the airport. Specifically, the PSP land use policies require that design features ensure an interior noise limit of 45 dBA CNEL and an exterior noise level of 60 dBA CNEL. Due to the location of the PSP’s noise contour overlapping with the City’s boundaries, the City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 62 August 2026
General Plan EIR determined that little or no specific mitigation would be required to ensure new residential development are below applicable noise thresholds. As such, upon adherence to applicable PSP land use policies, the General Plan EIR determined that implementation and buildout of the General Plan would have a less than significant impact.

The City would consider the proposed Project to have a significant effect on noise if it is determined that the project would result in:
a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies.
b) Generation of excessive groundborne vibration or groundborne noise levels. c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same noise impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan. As such, the proposed Project would not result in an increase in vehicular traffic nor would it introduce a substantial increase in stationary noise.

The Development Code Update, in and of itself, does not propose specific projects but aligns the Code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts to exterior and interior noise, transportation noise, vibration, or substantial aircraft noise.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

4.12 Parks and Recreational Resources
Summary of Analysis in the General Plan EIR
Parks and recreational resources impacts are discussed in Section 2.13, Parks and Recreational Resources, of the General Plan EIR. The General Plan EIR determined that future development and redevelopment facilitated by the proposed General Plan Update would result in a population of approximately 105,532 new residents in the City. As such, the General Plan Update would result in an increased demand for existing and future parks and recreational facilities. The General Plan EIR states that Section 9.106.040 of the CCMC requires the City to dedicate land and/or require payment of in-lieu fees for the provision of parkland at a standard of 3 acres per 1,000 residents. With payment of fees and dedication of parkland, the General Plan EIR determined that the City would meet the parkland standards even with the increased population growth. Furthermore, the General Plan Update includes goals, policies, and programs (Parks and Recreation Element Goal 1, Policy 1.4, and Program 1.4.2) which establishes alternative modes of transportation and therefore, provides new recreational opportunities. With implementation of goals, policies, and programs and payment of in-lieu fees, the General Plan EIR determined that implementation and buildout of the General Plan would have a less than significant impact.

As it relates to the expansion of construction of recreational facilities, the General Plan EIR determined that the proposed General Plan Update includes 3,760 acres of land dedicated as open space and 125 acres established for schools and libraries. Based on the projected population growth, a total of 317 acres of new parkland would be required and a total of 478 acres of parkland would be required to meet the city’s buildout population of 159,998 residents (existing and new residents combined). Each future recreational facility would be evaluated on a project-by-project basis to ensure that environmental impacts are minimized or mitigated, as needed. As such, the General Plan EIR determined that implementation and buildout of the General Plan would have a less than significant impact.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same parks and recreational facility impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

PR-1 The City shall maintain and, where appropriate, upgrade existing facilities and diversify activities programming.

PR-2 The City shall periodically conduct a needs assessment for recreation programs and services with local residents.

PR-3 The City shall maintain and where possible expand use of joint-use agreements with the Palm Springs Unified School District to use school properties for public use during nonschool hours.

4.13 Population, Housing and Socio-Economic Resources
Summary of Analysis in the General Plan EIR
Population, housing, and socio-economic impacts are discussed in Section 2.14, Population, Housing, and Socio-Economic Resources, of the General Plan EIR. As it relates to substantial unplanned population growth, the General Plan EIR determined that implementation of the General Plan Update would not in itself result in any population growth. However, implementation of the General Plan Update would include a land use plan and policies that would facilitate new housing and businesses. The General Plan EIR determined that the General Plan Update would accommodate up to approximately 33,396 additional residential units, resulting in a total population of 159,998 residents at buildout. The General Plan EIR determined that the population growth is considered substantial. However, the proposed General Plan Update would facilitate new development in vacant land. The projected population growth is planned and would occur over many years. As such, impacts were determined to be less than significant.

As it relates to the displacement of existing residents or housing, the General Plan EIR determined that implementation of the General Plan Update would not increase residential densities on currently developed land. Instead, buildout of the General Plan Update would occur primarily on currently vacant land. As such, the General Plan EIR determined that the General Plan Update would not displace existing residents or housing, and no replacement housing would be required. Thus, the General Plan EIR determined that implementation and buildout of the General Plan would have a less than significant impact.

According to the General Plan EIR, the planning area does not contain any disadvantaged communities, as designated by CalEPA. Thus, the General Plan EIR determined that implementation and buildout of the General Plan would have no impact on disadvantaged communities.

However, these districts and their standards would be consistent with the 2040 General Plan. The proposed Project would update but not eliminate the fundamental regulations and requirements of the Development Code, such as meeting design and development standards. The proposed Project would align the Development Code with the General Plan and ensure it regulates the types of land uses and development envisioned in the General Plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same population, housing, and socio-economic impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

As the planning area does not contain any disadvantaged communities, the proposed Project would not result in increased density or more development than was envisioned in the General Plan that would have an impact on disadvantaged communities.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

4.14 Public Utilities and Service Systems
Summary of Analysis in the General Plan EIR
Public Services
Public services are discussed in Section 2.15, Public Utilities and Service Systems, of the General Plan EIR. The General Plan EIR determined that implementation of the General Plan would result in development of up to 33,396 new dwelling units, an additional 8,937,897 square feet of new commercial structures, and an additional 15,564,546 square feet of industrial space within the city. As it relates to fire protection services, the introduction of new development and residents would increase the overall demand for fire services within the city. Funding for additional fire protection services would be provided via the City’s general fund which is maintained by the collection of taxes. Additionally, future projects within the city would be required to pay Development Impact Fees to offset the project-related demand for existing fire services. Furthermore, future developments would be required to be constructed consistent with current fire regulations and provide fire safety features. With implementation of policies, compliance with applicable design requirements, and payment of development fees, impacts on fire protection services were determined to be less than significant.

As it relates to police protection, the increase in development proposed under the General Plan would increase demands for police protection. The City’s Police Department’s Strategic Plan has a service ratio goal of no less than one officer for every 1,000 residents. As such, the General Plan EIR determined that future development has the potential to impact response times. The increase in police protection services would require the hiring of additional staff which would be funded by the City’s general fund and grant funding. New police stations or expansion of existing police facilities could be required, however, each future facility would be evaluated on a project-by-project basis to ensure that environmental impacts are minimized or mitigated, as needed. Furthermore, the General Plan includes a policy (Public Services and Facilities Element Policy 1.3) that requires the City to provide adequate and timely expansion of police protection capabilities, services and facilities to meet future development demands. With implementation of applicable policies, impacts on police services were determined to be less than significant.

As it relates to schools, the increase in dwelling units and subsequent population increase would increase the enrollment of students in schools within the city. The General Plan EIR determined that a worst-case scenario would result in approximately 4,983 new elementary/middle/high school students being generated during the buildout of the General Plan. While the buildout of the General Plan would generate new students, the Palm Spring Unified School District (PSUSD) would collect school impact fees as new development (residential, commercial, industrial, etc.) occurs in accordance with Senate Bill 50 and Policy 3.5 of the Public Services and Facilities Element. Upon collection of school impact fees, impacts associated with schools were determined to be less than significant.

The General Plan EIR determination on park impacts is summarized in Section 4.12, Parks and Recreational Resources, of this Addendum.

As it relates to library services, the increase in dwelling units and subsequent population increase in the City would gradually increase the demand for library services. The General Plan EIR determined that new library facilities or expansion of existing facilities could be required as library demands increase.

However, each facility would be evaluated on a project-by-project basis to ensure that environmental impacts are minimized or mitigated, as needed. Furthermore, the General Plan includes a policy (Public Services and Facilities Element Policy 3.4) which requires the City to coordinate with the Riverside City of Cathedral City

County Library System. With implementation of applicable policies, impacts on library services were determined to be less than significant.

While the General Plan EIR determined that the General Plan would have a less than significant impact on public services (i.e., impacts on fire protection, police services, parks, schools, libraries), Mitigation Measures PS-1 through PS-13, as described below in “Applicable General Plan EIR Mitigation Measures,” would ensure that impacts related to public services continue to be less than significant.

Mitigation Measures PS-1 through PS-13 were derived from the Public Services and Facilities Element and serves to reinforce actions taken by the City and project applicants.

Utilities Service Systems
Utilities service systems are discussed in Section 2.15, Public Utilities and Service Systems, of the General Plan EIR. As it relates to the construction, relocation, or expansion of utilities, the General Plan EIR would result in a population of approximately 159,998 residents and up to 33,396 new dwelling units, an additional 8,937,897 square feet of new commercial structures, and an additional 15,564,546 square feet of industrial space. Future development facilitated by the General Plan would connect to existing or expanded utility infrastructure. To ensure adequate capacity, utility providers have plans that would expand capacity, as needed, based on future demands. New utility facilities or expansion of existing facilities would be evaluated on a project-by-project basis to ensure that environmental impacts are minimized or mitigated, as needed. Additionally, the General Plan contains policies (Public Facilities Sub-Element Policy 4.1 and 4.2 and Water, Sewer and Utilities Sub-Element Policy 5.1 and 5.2) that encourages the City to work alongside providers to allocate budget, land, and sites for future infrastructure development. With implementation of applicable policies, the General Plan EIR determined that impacts are less than significant.

As it relates to sufficient water supplies, the General Plan EIR determined that buildout of the General Plan would result in an increase in population and land development when compared to the existing land use plan. Buildout of the General Plan would have a total water demand of approximately 20,769.86 acre-feet per year. The City is served by the Cucamonga Valley Water District (CVWD) and Desert Water Agency (DWA) which has adequate water supply to meet anticipated demands for normal, single dry, and multiple dry water years. The General Plan EIR determined that the projected water demands from the buildout of the General Plan would represent approximately 8.5 percent of the CVWD and DWA combined water demand for the year 2040. With implementation of policies (Water, Sewer and Utilities Sub Element Policy 6.2) that require coordination with water agencies and applicable policies that reduce water demands, the General Plan EIR determined that impacts are less than significant.

As it relates to wastewater, the General Plan EIR states that the City is currently served by CVWD and DWA. Wastewater generated by the city is treated at CVWD’s Cook Street wastewater reclamation plant which treats approximately 15 million gallons of wastewater a day. The General Plan EIR determined that buildout of the General Plan would potentially require new wastewater connections to existing wastewater treatment lines. Additionally, CVWD and DWA have plans for the expansion of existing facilities based on future demands. Additionally, the General Plan includes policies (Water, Sewer and Utilities Sub-Element Policy 6.1, 6.2, 6.3) which encourage an integrated, city-wide sewer system and monitoring of resource management activities. New wastewater facilities or expansion of existing facilities would be evaluated on a project-by-project basis to ensure that environmental impacts are minimized or mitigated, as needed. With implementation of applicable policies, the General Plan EIR determined that impacts are less than significant.

As it relates to solid waste and compliance with solid waste reduction regulations, the General Plan EIR determined that buildout of the General Plan would result in a generation of approximately 90,017 tons City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 72 August 2026
of solid waste per year after considering Assembly Bill 939. Assembly Bill 939 requires a 50 percent diversion of solid waste from landfills. Waste generated by the city is disposed of in three landfills which has a combined remaining capacity of 178.8 million cubic yards and thus, waste generated by General Plan buildout would not exceed the landfills’ remaining capacity. With adherence to Assembly Bill 939 and applicable policies within the General Plan, the General Plan EIR determined that impacts are less than significant.

While the General Plan EIR determined that the General Plan would have a less than significant impact on utilities service systems, Mitigation Measures PS-14 through PS-25, as described below in “Applicable General Plan EIR Mitigation Measures,” would ensure that impacts related to utilities service systems continue to be less than significant. Mitigation Measures PS-14 through PS-25 were derived from the Public Services and Facilities Element and serves to reinforce actions taken by the City and project applicants.

The City would consider the proposed Project to have a significant effect on public services if it is determined that the project will:
a) 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) Parks.
v) Other public facilities.

Additionally, the City would consider the proposed Project to have a significant effect on utilities service systems if it is determined that the project will:
a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects.
b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years. c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments.
d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals.

Proposed Project Analysis
Public Services
Policies and actions in the General Plan that were referenced in the General Plan EIR would reduce impacts to the greatest extent possible. These policies and actions would continue to be required with implementation of the Development Code Update. The proposed Project would update the Development Code for consistency with the 2040 General Plan. The update would result in the creation of new zoning districts as well as the elimination of existing districts; the renaming of existing districts; the consolidation of existing districts; as well as the modification or modernization of requirements for development and land uses within various other districts. However, these districts and their standards would be consistent with the 2040 General Plan. The proposed Project would update but not eliminate the fundamental regulations and requirements of the Development Code, such as meeting design and development standards. The proposed Project would align the Development Code with the General Plan and ensure it regulates the types of land uses and development envisioned in the General Plan.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same public services impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 74 August 2026
The Development Code Update, in and of itself, does not propose specific projects but aligns the zoning code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts to utilities service systems (i.e., wastewater, water, electricity, natural gas, etc.).

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

4.15 Transportation
Summary of Analysis in the General Plan EIR
Transportation impacts are discussed in Section 2.16, Transportation, of the General Plan EIR.

According to the General Plan EIR, the General Plan is not a land use nor a transportation project but instead, a broad-based policy document. The General Plan EIR utilized three methods to determine if the General Plan would result in conflict with State CEQA Guidelines Section 15064.3(b):
• Does the Project’s VMT exceed an applicable threshold of significance? o The City does not have an applicable VMT threshold however, the General Plan EIR determined that the General Plan would result in a net reduction in trips and VMT when compared to the existing General Plan.
• Is the Project within one-half mile of an existing major transit stop or stop along an existing high quality transit corridor?
o The city is served by existing transit services provided by the SunLine Transit Agency.

The General Plan would require continue coordination with SunLine Transit Agency to ensure that the transit system can adequately serve future development and population within the city.
• Does the Project decrease VMT in the project area compared to existing conditions? o While the General Plan would facilitate new development and growth within the city, the General Plan EIR determined that the General Plan would result in a net reduction in trips and VMT when compared to the existing General Plan.

The General Plan EIR determined that the proposed Circulation and Mobility Element include policies and programs (Policy 1, Policy 2, Program 5.A, and Policy 11) that would reduce the City’s VMT.

Mitigation Measures TM-1 through TM-7 are discussed below to further reduce the City’s impacts related to transportation and VMT. Furthermore, the General Plan EIR determined that the implementation of Complete Streets concepts provided in the City’s Active Transportation Plan would contribute to overall reduction in VMT, vehicle trip length, and vehicular delay. With implementation of these policies, programs, and implementation of Complete Streets concepts, the General Plan EIR determined that the General Plan would not conflict with or be inconsistent with CEQA Guidelines Section 15064.3(b) and a less than significant impact would occur.

The General Plan EIR determined that as future development is proposed, roadway design and improvements would be reviewed by City staff and other agencies, such as Caltrans, to ensure that sharp curves, dangerous intersections, or other hazardous design features are avoided. Circulation and Mobility Element Policy 4 requires development proposals generating traffic volumes or impacts beyond the scope of the General Plan analysis to conduct project-specific traffic studies to ensure impacts are adequately mitigated. The General Plan EIR further determined that implementation of the Circulation and Mobility Element and the Active Transportation Plan would expand the City's multi-modal network, integrating vehicular and multi-modal travel to maximize roadway safety for all users. Circulation and Mobility Element Policies 1, 2, 5, 6, and 7 serve to ensure a safe and compatible mix of transportation modes. The General Plan EIR noted that vehicular incompatibilities associated with farm equipment are not anticipated because the City does not contain farmland. With implementation of these policies and standard project-level review, the General Plan EIR determined that the General Plan would not City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 78 August 2026
substantially increase hazards due to geometric design features or incompatible uses and a less than significant impact would occur.

The General Plan EIR determined that the General Plan would not propose any land use designation or physical improvements that would result in inadequate emergency access. However, new development under the General Plan has the potential to affect emergency access during and after construction. Nevertheless, the General Plan EIR noted that the City Fire and Police Departments and other agencies, as appropriate, would continue to review plans and inspect development sites to ensure adequate emergency access is provided, including vehicular access, turn-around spaces, fire lanes, signage, secondary access points, and access to gated or locked entrances. In addition, the General Plan Emergency Preparedness Sub-Element addresses the identification, establishment, and maintenance of citywide emergency access and evacuation routes (Program 2.B, Policy 3, Program

3.A). With implementation of these General Plan policies and programs, along with standard City requirements, the General Plan EIR determined that the General Plan would have a less than significant impact on emergency access.

The City would consider the proposed Project to have a significant effect on transportation if it is determined that the project will:
a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities.
b) Conflict or be inconsistent with CEQA Guidelines § 15064.3, subdivision (b). c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment). d) Result in inadequate emergency access.

The proposed Project would implement the 2040 General Plan, thereby resulting in the same transportation impacts from new development as evaluated in the certified General Plan EIR. In addition, the proposed Project would not result in increased density or more development than was envisioned in the General Plan.

City of Cathedral City

DEVELOPMENT CODE UPDATE
EIR Addendum PAGE 79 August 2026
The Development Code Update, in and of itself, does not propose specific projects but aligns the Code to match the General Plan. Because it is a regulatory update, the Development Code Update would not, in and of itself, result in impacts to transportation such as conflicting with a program or plan addressing the circulation system, conflict with CEQA Guidelines § 15064.3, subdivision (b), substantially increase hazards from geometric design or incompatible uses, or result in inadequate emergency access.

Future development facilitated by the Development Code Update would undergo project-specific developmental review, including design review where applicable, and would be subject to adopted development regulations. Therefore, the proposed Project would not result in any new significant impacts or a substantial increase in the severity of the impacts identified in the General Plan EIR.

Applicable General Plan EIR Mitigation Measures:

TM-1 Cathedral Canyon Drive from Perez Road to Ramon Road shall be identified as a special study corridor for transportation/mobility. The City shall study this corridor and monitor its operations on an ongoing basis to develop recommendations for improvements. Specific tasks shall involve identifying the corridor’s strengths, weaknesses, and opportunities for improvements. Recommendations should balance the needs to improve mobility, safety, parking, and the area’s appearance.

TM-2 The Public Works Department shall establish and implement a prioritized roadway and intersection study and analysis program to assure the provision of adequate future rightsof-way and facilities at critical roadways and intersections. This program may be incorporated into the five-year Capital Improvements Program, which should be reviewed and amended, as necessary, annually.

TM-3 A planning and engineering project review checklist will be developed, which addresses all major roadway components and ensures compliance with the provisions of the Circulation and Mobility Element and the Active Transportation Plan. The checklist will be used in reviewing development proposals.

TM-4 Identified roadway segments and intersections with the potential to operate at LOS E or worse at General Plan buildout shall be designated as “Special Study Zones” where detailed analysis shall be conducted to minimize further degradation of operating conditions at these locations and to ensure that they operate at acceptable LOS at General Plan buildout.

TM-5 The City shall encourage and if necessary, require developers to explore alternative designs of streets and other transportation facilities by providing, as appropriate, information on Complete Streets design concepts and standards that may meet basic performance and safety needs, while still being responsive to the New Urbanism principles.

TM-6 The City shall apply to all development plans the adopted roadway classifications, and implement the Active Transportation Plan to maximize walking, bicycling, and use of LSEVs, and assure safe and efficient connections to City-wide and regional multi-modal facilities.

TM-7 When initiating review of development proposals, the City shall consult and coordinate with SunLine and solicit comments and suggestions on bus stops and other public transit facilities and design concepts, including enhanced handicapped access, that should be integrated into project designs.
