(Murrieta General Plan 2035 FEIR, Page 5.13-30 through Page 5.13-47) 2 Proposed Project - No Substantial Change From Previous Analysis With the scope of proposed changes under this code amendment, there are no changes in circumstances under which the project is undertaken and/or "new information of substantial importance" that result in one or more substantial adverse physical impacts associated with the violation of any water quality standards or waste discharge requirements; substantially deplete groundwater supplies or interfere with groundwater recharge; alter the existing drainage pattern of the site resulting in erosion or siltation; alter the existing drainage pattern of the site or increase the rate or amount of surface runoff in a manner that would result in flooding; create or contribute runoff water that would exceed the capacity of storm drain systems; degrade water quality; place of housing within, or impeding or redirecting flood flows, or expose people or structures to flooding; or inundate by seiche tsunami or mudflow. The Project is located within the planning area of the San Diego Regional Water Quality Control Board (RWQCB). To address stormwater and accidental spills within this environment, any new individual development project must ensure that site development implements an SWPPP and a National Pollutant Discharge Elimination System (NPDES) to control potential sources of water pollution. To address stormwater and accidental spills within this environment, any new development project must ensure that site development implements an SWPPP and a National Pollutant Discharge Elimination System (NPDES) to control potential sources of water pollution that could violate any standards or discharge requirements during construction and a Water Quality Management Plan (WQMP) to ensure that project-related after development surface runoff meets discharge requirements over the short- and long-term. Individual development projects would also have demonstrate compliance with water groundwater supplies consistent with State legislation and review for 100-year flood hazard areas as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map; analyzing a site for the potential for failure of a levee or dam; and inundation by seiche, tsunami, or mudflow. Individual projects would be reviewed for consistency with the Infrastructure, Conservation, and Safety Elements Goals and Policies for hydrology and water quality. Mitigation measures would be carried forward as applicable as described above and/or further customized based on the existing site’s characteristics.
Given this background, there is no evidence that the Project would require a major change to the ND and General Plan FEIR. The Project would not result in any new significant impacts which were disclosed and analyzed by the ND (Water) and General Plan EIR (Hydrology, Drainage and Water Quality) would result and no new or increased impacts are forecasted to result, nor would a substantial increase in the severity of impacts with implementation of the Hydrology, Drainage and Water Quality Goals, Policies, and Mitigation Measures on a project-level basis.

Individual development projects would still be subject to project and environmental review under CEQA and collection of mitigation fees to offset the increased demand for both public services and recreational opportunities. For Fire Protection, individual development projects would be subject to General Plan 2035 Goals and Policies.

Based on the foregoing discussion, there is no evidence that the Project would require a major change to the ND. The project would not result in any new significant impacts which were disclosed and analyzed by the 1997 Draft Comprehensive Development Code Negative Declaration for this issue area (Public Services) or General Plan 2035 FEIR (Police, Schools, Parks, Public Facilities), nor would a substantial increase in the severity of impacts from that described in the ND or FEIR would result.
XIV. RECREATION
Since the previous ND was adopted, and when certification of the EIR occurred, are there any changes in the project, changes in circumstances under which the project is undertaken and/or "new information of substantial importance" that cause effects to Recreation including: a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment?
Comprehensive Development Code Negative Declaration & Proposed Project Impacts to “Recreation” were determined to have a “Less Than Significant Impact” in terms of increasing the demand for neighborhood or regional parks or other recreational facilities, and affecting existing recreational opportunities.
This Project updates and clarifies existing administrative planning and engineering code processes and standards that currently exists within MMC which apply throughout the City and within hillside areas.

The Project updates and clarifies existing administrative planning and engineering code processes and standards that currently exists within MMC which apply throughout the City and within hillside areas.
Individual development projects would still be subject to subsequent environmental review under CEQA with a site-specific analysis. Based on the scope of these updates, one can reasonably conclude that it would not increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated, or create new recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment. Furthermore, individual development projects will be benchmarked against the Murrieta General Plan 2035 Goals and Polices with respect to Parks and Recreational Facilities for payment of impacts fees and/or constructing onsite recreational facilities.

XV. TRANSPORTATION/TRAFFIC -- Since the previous ND was adopted, and when certification of the EIR occurred, are there any changes in the project, changes in circumstances under which the project is undertaken and/or "new information of substantial importance" that cause effects to transportation/traffic including: (a) a conflict with an applicable plan, ordinance, or policy, establishing measures of effectiveness for the performance of the circulation system; (b) a conflict with an applicable congestion management program; (c) result in a change in air traffic patterns; (d) a substantial increase in hazards due to a design feature or incompatible use; (e) inadequate emergency access; or (f) conflicts with adopted policies supporting alternative transportation”
YES NO
Comprehensive Development Code Negative Declaration, General Plan EIR, and Proposed Project Negative Declaration
Impacts to “Transportation/Traffic” were analyzed under “Transportation/Circulation”. The outcome from this analysis was determined to have a “Less Than Significant Impact” in terms of increasing vehicle trips or traffic congestion; creating hazards to safety from design features (e.g. sharp curves or dangerous intersections), incompatible uses (e.g. farm equipment) or barriers for pedestrians or bicyclists; leading to inadequacy for emergency access or access to nearby uses; resulting with insufficient parking capacity on-site or off-site; conflicting with adopted policies supporting alternative transportation (e.g. bus turnouts, bicycle racks); creating air or rail traffic impacts.
As described within the ND:
..The document regulates the following uses in conformance with the General Plan and applicable local, state and federal laws. These include, but are not limited to: affordable housing, air quality, geologic/seismic hazards, hazardous materials storage, hillside development, infrastructure mitigation, landscaping, lighting on project sites and for the regional benefit of Mount Palomar, noise, nonconforming structures, parking and loading of vehicles, signage, solid waste/recycling, transportation demand management, tree preservation, and vibrations.
..Studies will be required at the time of project development to assess the individual impacts to these resources in compliance with the California Environmental Quality Act. (Comprehensive Dev. Code, IS11)1 General Plan 2035 SEIR (2020)
Impacts to Transportation/Traffic were assessed under the General Plan SEIR under “Traffic and Circulation” The impacts were determined to remain below a level of significance with the implementation of compliance with the goals and policies of the General Plan 2035:

Level of Significance Before Mitigation: Potentially Significant Impact ..Impact Conclusions:
Intersections:
With the potential improvements, traffic operations at most of the intersections are forecast to improve to either acceptable conditions (LOS D or better) or to a level considered less substantial (below “without project” levels). However, at the following intersections, feasible improvements were not identified, or improvement measures did not result in improved delays to below “without project” levels. Therefore, even with installation of the recommended improvements, implementation of the proposed Project would result in unavoidable traffic impacts at the following intersections:
Jefferson Avenue/Kalmia Street
Winchester Road (SR‐79)/Murrieta Hot Springs Road
Hancock Avenue/Los Alamos Road
Whitewood Road/Murrieta Hot Springs Road
Whitewood Road/Clinton Keith Road
Roadway Segments:
As discussed above, based on the results of the traffic impact analysis, seven (7) segments are forecast to be impacted as a result of the proposed Project’s land use modifications. Potential improvements to roadway segment operations are limited to roadway widening to increase capacity (as opposed to intersection improvements that include less impactful measures such as signal phasing modifications).
Thus, roadway segment improvements are not considered to be feasible. Therefore, implementation of the proposed Project would result in diminished levels
of service at the following roadway segments:
Clinton Keith Road east of California Oaks Road
California Oaks Road south of Clinton Keith Road
Jefferson Avenue south of California Oaks Road;
Los Alamos Road between Monroe Avenue and Hancock Avenue Murrieta Hot Springs Road between I-15 and I-215
Murrieta Hot Springs Road between Alta Murrieta Drive and Whitewood Road Murrieta Hot Springs Road between Whitewood Road and Margarita Road ..IMPLEMENTATION OF THE PROPOSED PROJECT COULD INCREASE HAZARDS DUE TO A GEOMETRIC DESIGN FEATURE OR INCOMPATIBLE USES.

..DEVELOPMENT ASSOCIATED WITH IMPLEMENTATION OF THE PROPOSED PROJECT AND
CUMULATIVE DEVELOPMENT COULD RESULT IN CUMULATIVELY CONSIDERABLE TRAFFIC AND CIRCULATION IMPACTS.
Level of Significance Before Mitigation: Significant Impact. ..With the potential improvements, traffic operations at most of the intersections are forecast to improve to LOS D or better, or to a level considered less than significant (below “without project” levels). However, at five (5) intersections, feasible improvements were not identified, or feasible improvement measures did not result in improved delays to below “without project” levels. In addition, seven (7) roadway segments are forecast to operate at LOS D, E, or F. Potential improvements to roadway segment operations are limited to roadway widening to increase capacity (as opposed to intersection improvements that include less impactful measures such as signal phasing modifications). Thus, roadway segment improvements are not considered to be feasible. Therefore, buildout of the proposed Project would result in cumulatively considerable traffic and circulation impacts.
Mitigation Measures: No mitigation measures beyond the goals and policies identified in the 2011 and/or proposed Project referenced above are available.
Level of Significance After Mitigation:
Roadway Segments: Significant Unavoidable Impact for the seven (7) roadway segments identified as LOS D, E, or F listed in table 4.2-11 above. Less Than Significant Impact for all other studied roadway segments identified as LOS A, B, or C on table 4.2-11 above. 428

The Project is not proposing housing units or resulting in the increase in resident population which would affect transportation related issues. Individual development projects would still be subject to environmental review under CEQA, provide site specific transportation which would analyze intersection impacts, level of service (LOS), Vehicles Miles Traveled (VMT) studies which would be benchmarked against City’s adopted VMT Guidelines, require review against the General Plan Circulation Element for both vehicular and nonvehicular access, and require collection of mitigation fees through the Transportation Uniform Mitigation Fee (TUMF) program, and identification of potential off-site improvements to reduce transportation level impacts to below a level of significance.

Based on the foregoing discussion, there is no evidence that the Project would require a major change to the ND or the General Plan 2035 SEIR. The Project would not result in any new significant impacts which were disclosed and analyzed by the Comprehensive Development Code Negative Declaration for this issue area (Transportation/Circulation). the General Plan 2035 SEIR (Traffic and Circulation) did identify “significant unavoidable impacts” for five intersections and seven road segments; however these updates are outside the scope of creating new significant impacts or increase the severity of a previously identified significant impacts as previously analyzed in the Murrieta General Plan 2035 SEIR and no further environmental review is necessary for this topic. The SEIR identified mitigation measures to reduce the impacts to Traffic and Circulation which would be carried forward on future site-specific projects.
XVI. TRIBAL CULTURAL RESOURCES
Since the previous ND was adopted, and when certification of the General Plan 2035 EIR occurred, are there any changes in the project, changes in circumstances under which the project is undertaken and/or "new information of substantial importance" that cause effects to tribal cultural resources including: a) 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 b) 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 Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.
YES NO
Comprehensive Development Code Negative Declaration, General Plan EIR, and Proposed Project California Environmental Quality Act (CEQA) Guidelines, Section 15128, allows environmental issues for which there is no likelihood of a significant impact to not be discussed in detail or analyzed further in the ND. While “Tribal Cultural Resources” was not analyzed in detail, as outlined in CEQA Section 15128, there is no new information available that would indicate that these issues would result in new significant impacts based on the scope of the Project. The code updates under this Project modify and clarify existing planning and engineering standards to support future development throughout the City does not propose changes to existing land uses or density. Individual development projects would still be require compliance with both Assembly Bill 52 and Senate Bill 18 tribal consultation and be reviewed for consistency under CEQA. Through this process, site-specific Tribal Cultural Resources Mitigation Measures would be developed and implemented as required.
XVII. UTILITIES AND SERVICE SYSTEMS -- Since the previous ND was adopted, and when certification of the EIR occurred, are there any changes in the project, changes in circumstances under which the project is undertaken and/or "new information of substantial importance" that cause effects to utilities and service systems including: (a) exceedance of wastewater treatment requirements; (b) construction of new water or 430

Furthermore, individual development projects will be benchmarked against the Murrieta General Plan 2035 Goals and Polices with respect to Wastewater, Water Supply, and Solid Waste. For Wastewater, this includes Goals INF-1, CSV-1 and corresponding Policies INF-1.1 through INF-1.10, INF1.21, CSV-1.1 through CSV-1.4, CSV-1.6. For Water Supply, this includes Compliance with Goals CSV-1, CSV-2, CSV-9, CSV-15, INF-1 and corresponding Policies CSV-1.1 through CSV-1.6, CSV-2.1 through CSV-2.5, CSV-9.1 through CSV-9.9, CSV-15.5 through CSV-15.6, INF-1.1 through INF-1.10, INF-1.21 through INF-1.24. For Solid Waste, this includes Goal CSV-13 and corresponding Policies CSV-13.1 through CSV-13.7. Furthermore, the Project is not proposing housing units resulting in an increase in resident population which would affect utility and infrastructure-related issues. Individual development projects would still be subject to project and environmental review under CEQA, provide site-specific water capacity studies, septic/sewer capacity studies, provide Best Management Practices for drainage, demonstrate compliance with solid waste disposal needs; and demonstrate compliance with federal, state, and local statutes and regulations. Provided this background with these updates, there would not be any new information of substantial importance that would cause effects to utilities and service systems including: exceedance of wastewater treatment requirements; construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects; construction of new storm water drainage facilities or expansion of existing facilities which would cause the construction or which could cause significant environmental effects; availability of sufficient water supplies to serve the project from existing entitlements and resources; adequate wastewater treatment capacity to serve the project’s projected demand in addition to the provider’s existing commitments; sufficient permitted landfill capacity to accommodate the project’s solid waste disposal needs; or compliance with federal, state, and local statutes and regulations related to solid waste.
Based on the foregoing discussion, there is no evidence that the Project would require a major change to the ND or General Plan 2035 FEIR. The project would not result in any new significant impacts which were disclosed and analyzed by the Comprehensive Development Code Negative Declaration for this issue area (Utilities and Service Systems) or General Plan 2035 FEIR (Wastewater, Water, Solid Waste), nor there be a substantial increase in the severity of impacts that would result with compliance for review and implementation of the above described Goals and Policies. 439

Project Title: Hillside Ordinance Updates (DCA-2021-2396) Project Applicant: City of Murrieta
Description of Project: The “Project” is an ordinance amendment to revise Chapters 8.20 and 15.52 of the Municipal Code, and amend the City’s Development Code for the purpose of revising and updating Chapters 16.08, 16.14, 16.18,
16.22, 16.24, 16.28, and to add a new Sections 16.24.080, entitled “Exceptions”, 16.24.090, entitled “Reserved”, and
16.24.100, entitled “Hillside Overlay Map”. The main objective for bringing forward these updates is that when the hillside development standards were originally adopted in conjunction with the Comprehensive Development Code in 1997, these standards may have been over time misapplied and misinterpreted by project proponents and City staff as it relates to project review. The proposed updates will clarify and assist project proponents and City staff in the implementation of existing hillside criteria within an objective framework. This would be consistent with recent State housing legislation. Also, it should be noted that individual projects will still be subject to subsequent environmental review and site-specific analysis. Additionally, the updates being considered under Chapters 8.20 “Nuisances Generally” and 15.52, “Grading, Erosion and Sediment Control”, are proposed to be modified for consistency and referencing with the proposed modifications under Title 16.
The proposed action was reviewed for consistency with the adopted Negative Declaration for implementation of the Comprehensive Development Code on October 28, 1997, and the more recently benchmarked against the certified Murrieta General Plan Final FEIR in 2011 and Subsequent SEIR in 2021. These updates have been evaluated for consistency for the current “Project” proposal utilizing this Negative Declaration and the Murrieta General Plan Final FEIR and Subsequent SEIR in 2021 (SCH No. 2010111084), by the City of Murrieta.
Pursuant to Public Resources Code Section 21166 and CEQA guidelines 15162, the City has determined that: (1) there is substantial evidence that none of the conditions requiring preparation of a subsequent Negative Declaration exist, and (2) the City will rely on the previous environmental document, which adequately addresses this Project.
The proposed project _ would, or X would not introduce additional impacts or increase the severity of impacts beyond those already analyzed in the 1997 Comprehensive Development Code Negative Declaration.
Project Site Size: Citywide
Project Location: Citywide
Public Agency Approval: On September 15, 2026, the City of Murrieta City Council made the determination that the project qualified for 15162 Consistency Determination pursuant to Public Resources Code Section 21166 and California Environmental Quality Act (CEQA) guidelines Section 15162, Subsequent EIRs and Negative Declarations, with the second reading and consideration of adoption scheduled for October 6, 2026. 440
Statement of Reasons Supporting the Finding for an Addendum:
1. No substantial changes were proposed to the Project that would require major revisions of the previous ND and certification 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. No substantial changes would occur with respect to the circumstances under which the project is undertaken, which will require major revisions to the previous ND and EIR due to the involvement of any new significant environmental effects or a substantial increase in the severity of previously identified significant effects; and,
3. No new information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the ND was adopted and certification of the EIR occurred, shows any of the following:
(A) The project will have one or more significant effects not discussed in the previous ND and EIR; (B) Significant effects previously examined will be substantially more severe than shown in the previous ND and 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 measures or alternative; or
(D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous ND and EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.

RE: AIRPORT LAND USE COMMISSION (ALUC) DEVELOPMENT REVIEW – DIRECTOR’S
DETERMINATION
File No.: ZAP1147FV26
Related File No.: MA26228 (Zoning Text Amendment)
APN: Citywide
Dear Mr. Tracy,
As authorized by the Riverside County Airport Land Use Commission (ALUC) pursuant to its Resolution No. 2011-02, as ALUC Director, I have reviewed City of Murrieta Case No. MA26228 (Zoning Text Amendment), a proposal to modify the City of Murrieta Hillside Development Code to improve clarity, establish more objective standards, and provide greater consistency in the review of development on sloped properties. Additionally, the amendments establish methodology for measuring building heights on sloped lots, and requirements related to retaining walls, landscaping, and fuel modification areas.
The proposed amendments do not involve changes in development standards or allowable land uses that would increase residential density or non-residential intensity. Therefore, these amendments have no possibility for having an impact on the safety of air navigation within airport influence areas located within the City of Murrieta.
As ALUC Director, I hereby find the above-referenced project CONSISTENT with the 2012 French Valley Airport Land Use Compatibility Plan.
This determination of consistency relates to airport compatibility issues and does not necessarily constitute an endorsement of the proposed amendment.
If you have any questions, please contact me at (951) 955-6893.
Sincerely,
RIVERSIDE COUNTY AIRPORT LAND USE COMMISSION

ORDINANCE NO. 26-__
AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF MURRIETA, CALIFORNIA, AMENDING TITLE 16 OF THE MURRIETA MUNICIPAL CODE TO AMEND THE CITY’S DEVELOPMENT CODE CHAPTERS 16.08,
16.14, 16.18, 16.22, 16.24, AND 16.28. RELATED TO HILLSIDE
DEVELOPMENT STANDARDS
Summary: This Ordinance updates the City’s existing hillside regulations to promote and guide the orderly development of hillside areas through standards, which are specifically designed to address the unique challenges of such terrain. These updated regulations include, but are not limited to, provisions related to the measurement of building height on a slope with new graphics, clarification of applicability of a hillside area, the basis for a slope determination, when a hillside development permit is required, undeveloped and developed review criteria and applicability, updated definitions, hillside application materials, review procedures, slope grading techniques, the placement and height of retaining walls in hillside areas, site access, aesthetic and landscape treatments, exceptions to a permit, and incorporation of new hillside overlay into the municipal code.
WHEREAS, the City of Murrieta (“City”) proposes an amendment to the City's Development Code for the purpose of revising and updating Chapters 16.08, 16.14, 16.18, 16.22,
16.24, and 16.28 (“Development Code Amendment”); and
WHEREAS, with an effective date of December 18th, 1997, the City Council, after extensive public input, adopted Ordinance No. 182-97, which is generally known as the City of Murrieta Development Code, which contained provisions for hillside development regulations; and
WHEREAS, the purpose of this Ordinance is to promote and encourage the orderly development of hillside areas of the City by the application of regulations and requirements established to meet the particular problems associated with the development of hillside areas, including, but not limited to clarification of where hillside areas apply and related review processes, slope grading techniques, placement and height of structures, retaining walls, access, and atheistic treatments; and
WHEREAS, it was discovered by public input and verified by staff that these provisions are being applied Citywide, whereas the original intention was for these provisions to be applied to properties within the designated Hillside Overlay; and WHEREAS, DCA-2021-2396 includes updates in order to provide consistency and eliminate errors within the sections of the City's Development Code as identified for hillside areas and related development criteria; and
444
Ordinance No. 26-___
WHEREAS, on March 29, 2022, the City Council directed staff to review the hillside development standards and explained to staff that they were never meant to apply on a citywide basis; and
WHEREAS, on December 14th, 2022, the City held a first public workshop. This item was continued from that meeting and re-noticed for the January 25, 2023, meeting. No report or presentation was provided; and
WHEREAS, on January 25th, 2023, the City held a second public workshop at its Planning Commission meeting to provide and receive input from local residents and the Commission concerning hillside development standards in the City. Areas that were covered were inclusive of existing and proposed Hillside Overlay applicability, height allowances for structures, height measurement criteria, hillside slope applicability, average slope calculation, Prominent Ridgeline Overlay, and retaining wall criteria. The other items presented by staff were potential techniques to improve the readability of the existing Murrieta Municipal Code (MMC), examples of graphic exhibits that could be incorporated, highlights of areas to resolve code inconsistencies, ways to incorporate best practices, and suggestions from staff on how to simplify the standards to make them more user-friendly to both staff and applicants; and WHEREAS, on April 11th, 2023, staff hosted a presentation on the existing and proposed hillside standards. Staff held the workshop to obtain additional feedback from the community on the proposed hillside development standards. This additional outreach was conducted per direction from the prior Planning Commission for further community input and to provide transparency. Areas that were covered were inclusive of existing and proposed Hillside Overlay applicability, height allowances for structures, height measurement criteria, hillside slope applicability, average slope calculation, Prominent Ridgeline Overlay, and retaining wall criteria. There was time provided for questions/answers at the end of the presentation for feedback on the proposed updates from the public; and
WHEREAS, on June 28th, 2023, the City of Murrieta Planning Commission held a duly noticed public hearing on the proposed Development Code Amendment, at which the staff report was presented as well as written comments from the public regarding the need for the proposed code amendment and providing evidence in the record to support the findings required by the Murrieta Development Code Section 16.58.080; and
WHEREAS, on August 15, 2023, the City Council hosted its first workshop on this item.
The City Council requested additional information. Council members and staff discussed key standards for retaining wall heights, specifically discussing a 6-foot baseline and the balance between aesthetic landscaping and mandatory fire safety fuel modification zones. The session aimed to replace subjective guidelines with objective criteria for building on slopes, ensuring that new developments preserve the city’s visual ridgelines while providing a clearer, more predictable path for project approvals. The workshop was continued to a future meeting date; and WHEREAS, on March 5, 2024, the City Council hosted a second workshop on this item.
The discussion centered on a potential review process for retaining walls, clarifying building 445
Ordinance No. 26-___
height measurements on sloped terrain, and ensuring the "Hillside Overlay" maps accurately reflect local topography to avoid unnecessary burdens on flat-land homeowners. Crucially, the Council worked to harmonize aesthetic screening requirements with mandatory state fire safety and fuel modification mandates, prioritizing the protection of prominent ridgelines while ensuring the code aligns with current California law. Due to additional time needed for the discussion and feedback, the workshop was continued for a second time; and WHEREAS, on June 17, 2025, the City Council hosted a third workshop on this item. The direction/feedback from the Council was that detailed examples of standards from other localities and more of them were needed in order to assist the Council with moving forward; and WHEREAS, on October 21, 2025, the City Council held its fourth workshop on this item. The discussion centered on the following areas, where the Council reached consensus on key Focus Topics with the Applicability of Standards; Identifying The City’s Hillside Areas: 20 Percent Slope Versus 25 Percent; 25 Percent Slope Criteria; Specific Plans; and the use of Geographic Info. Systems (GIS) And Average Slope Formula; and WHEREAS, on November 18, 2025, the City Council conducted its fifth workshop on this item, during which several key policy directions and considerations were identified, including, but not limited to, the following: that updates to retaining wall regulations should be addressed on a citywide basis rather than limited to Hillside Areas; that standards should provide both flexibility through defined options and sufficient specificity, particularly with respect to retaining wall design; that retaining wall design standards should be implemented citywide; that color palettes for retaining walls should generally consist of muted tones, with specific shades or blends established in advance to ensure a consistent and desirable aesthetic; that earthtone colors may be appropriate for hillside structures; that retaining walls exceeding six feet in height may, in certain circumstances, be excessive on a citywide basis; that tiered retaining walls incorporating landscaping are a preferred design feature; that Keystone-style walls with integrated landscaping are also desirable; that landscaping is a priority consideration for the Council, including the establishment of larger plant sizes earlier in the development process; that additional clarification from the Fire Department is necessary regarding planting requirements within Fuel Modification Plans; and that distinctions between rural residential and tract home front-yard setbacks should be more clearly defined; and, WHEREAS, on February 3, 2026, the City Council held its sixth and final workshop on the topic. The Murrieta City Council discussed key topics, including retaining walls, landscaping standards, fire severity zones, distinctions between developed and undeveloped properties, and the relationship between hillside and citywide standards. Public input raised concerns about the visual and regulatory impacts of retaining walls, tree removal credits, definitions of undisturbed land, conditions of approval, and broader issues such as Senate Bill 9 and insurance implications.
Following that discussion, the Council reached consensus to provide direction on specific retaining wall types (including geogrid, CMU, and keystone walls) for hillside areas, suggested requiring earlier installation of larger landscaping, and that a separate ordinance was needed on a city-wide basis as it relates to retaining walls, along with direction to staff that the definitions of developed and undeveloped land for hillside areas need to be clearly defined. 446

SECTION 4. Section 16.18.080 (Height Measurement and Height Limit Exceptions) of the Murrieta Municipal Code is hereby amended in its entirety to read as follows:
“All structures shall meet the following standards relating to height, except for fences and walls, which shall comply with Chapter 16.22 (Fences, Hedges, and Walls).
A. Maximum Height. The height of structures shall not exceed the standard established by the applicable zoning district in Article II (Zoning Districts and Allowable Land Uses) or for structures within a Hillside Area under Section 16.24.020.A. In addition, the maximum height for structures on a specific parcel shall be measured as follows:
1. Establishing the high point and low point on the property as reference grade points as follows:
a. A measurement is taken from the lower of existing or proposed grade, 5 feet away from the lowest grade point around the structure in accordance with Figure 16.18-1. This point shall be the low reference grade point. The highest point anywhere on the structure may not exceed the elevation of that low grade point by more than the allowable height plus the grade differential between the low point of structure and high point of structure (excluding items as detailed under Section 16.18.080(B) (Exceptions to Height Limits)), but in such case where the actual grade differential exceeds 10 feet, only a maximum of 10 feet may be added to the maximum allowable height per the zone. The measurement is the difference in elevation between the highest and the lowest adjacent ground elevation surrounding the building.
FIGURE 16.18-1
MEASUREMENT LOCATIONS
b. If the difference in elevation is 10 feet or less, the reference grade point is established at the highest adjacent ground elevation. See Figure 16.18-2. If the difference in elevation is greater than 10 feet, the reference grade point is established at 10 feet above the lowest adjacent ground elevation. See Figure 16.18-3. For stepped or terraced buildings, the building height is the overall height as illustrated in Figures 16.18-4 and Figure 16.18-5.

MEASUREMENT WITH PAD CONFIGURATION
B. Exceptions to Height Limits. Exceptions to the height limits identified in this development code shall apply in the following manner:
1. Roof-mounted Features. Roof-mounted features including chimneys, cupolas, clock towers, elevator equipment rooms, equipment enclosures, and similar architectural features shall be allowed, up to a maximum of fifteen (15) feet above the allowed structure height. The total square footage of all structures above the heights allowed in the zoning districts shall not occupy more than twenty-five (25) percent of the total roof area of the structure. Greater height or area coverage may be allowed subject to the approval of a minor conditional use permit in compliance with Chapter 16.52.
2. Parapet Walls. Fire or parapet walls may extend up to four feet above the allowable height limit of the structure.
3. Public Assembly, Hotels, Class "A" Office and Public Structures. Places of public assembly including churches, schools, assembly halls, Class "A" office buildings greater than three (3) stories, hotels and other similar structures may exceed the established height limit by one (1) foot for every two (2) feet that the minimum required front, rear and side yard setbacks are increased. The increase in the front, rear and side yard setbacks is determined by averaging the total of the increased building setbacks at the closest point on all sides. The maximum additional height allowed is thirty (30) feet above the height limit established for the applicable zoning district.

“16.24.010 Purpose.
The purpose of this chapter is to provide regulations for the development of areas in the City that, because of their topography, require special consideration to ensure that they are developed in a way that substantially maintains their natural character and environmental and aesthetic values to implement the City’s General Plan, and to provide for the safety, health, and welfare of the public by:
A. Providing guidelines and standards for development in visually sensitive Hillside Areas to minimize the adverse impacts of grading and to promote the goals and objectives of the City’s General Plan;
B. Maintaining an environmental equilibrium consistent with existing vegetation, wildlife, soils, geology, slopes, and drainage patterns, and to preserve natural topography and scenic character, including canyons, creeks, knolls, rock outcrops, and ridgelines whenever feasible; C. Reasonably consider development proposals that feature water conservation and aquifer recharge techniques;
D. Reasonably consider development proposals that are sensitive to fire, flood, slide, erosion, pollution, or other safety hazards;
E. Reasonably consider sensitive development through flexible design and innovative arrangement of building sites by utilizing variable lot sizes, clustering, and setback variations; F. Utilizing nontraditional design standards for streets and hillside grading where development quality and public safety are not affected;
G. Reasonably consider developments that incorporate desirable existing features of land (e.g., natural vegetation, viewsheds, topographic features);
H. Protecting significant natural areas for ecologic purposes, educational, and other scientific study purposes; 1. Encouraging the use of drought-tolerant plant material to protect slopes from soil erosion and slippage, preserve natural watershed, minimize fire hazard, and minimize the scarring and deformation of the natural landscape;
I. Limiting the impact of cut slopes on adjacent developed and undeveloped properties; and J. Providing for appropriate intensity of development (e.g., density, massing, etc.) through a variety of design techniques to ensure that development intensity decreases as slopes become steeper (e.g., lot sizes appropriate for steeper topography and separation of structures sufficient to preserve a viewshed).

TABLE 16.24-2
HILLSIDE DEVELOPMENT STANDARDS
% Natural
Slope
Category
Standards
465
Ordinance No. 26-___
Under 25% This is not considered a hillside condition. Please note that slope calculations shall not be rounded to the nearest whole number.
25% and
Over but
less than
50%
This is a hillside condition. Development within this slope category is limited to the less visually prominent slopes of a subject site, where it can be demonstrated that grading, vegetation removal, safety, aesthetic, and other environmental impacts are minimized. Potential impacts from site access and roadways shall be minimized by following natural contours or using grade separations. Proposed structures shall blend with the natural landform through their shape, material, and utilization of natural occurring color(s). Please note that slope calculations shall not be rounded to the nearest whole number.
50% and
over(1)
This is an excessive slope condition, and development is prohibited. (1) This applies to the property as a whole.
B. Site Design.
1. Projects shall incorporate clustering, variable setbacks, multiple orientations, and other site planning techniques to preserve open spaces, protect natural features, and offer views to residents.
2. When clustering techniques are utilized, the minimum lot sizes may be decreased to five thousand (5,000) square feet when it is necessary to preserve sensitive lands (e.g., hillsides, creeks, habitat areas, etc.). Lots may be allowed smaller than five thousand (5,000) square feet, but not smaller than four thousand (4,000) square feet, for up to twenty (20) percent of the total approved lots and only under an approved specific plan when necessary to preserve sensitive and Hillside Areas. Lots under five thousand (5,000) square feet are prohibited in slope areas of twenty-five (25) percent or greater.
C. Driveways and Roadways.
1. Driveways shall be designed in a manner as to when a vehicle is entering a public and /or private streets, adequate sight distance shall be maintained as determined by the City Engineer or their designee.
2. Driveways shall not be located within three feet of a side property line. Exceptions to this standard may be considered based on lot size, percentage of slope, drainage facilities and use as a common driveway by the City Engineer or their designee.
3. Only slopes less than fifty (50) percent (2:1) shall be permitted adjacent to driveways.
4. Driveway grades above fifteen (15) percent may only be considered by the City Engineer or their designee when driveways are aligned with the natural contours of the land, and are necessary to achieve site design, and safety considerations to the satisfaction of the building and safety official, City Engineer, or designee, and fire code official. Design considerations shall be employed, including the use of vertical curves. On proposed driveways with a slope greater than fifteen (15) percent, a coarse, all-weather paving material (e.g. asphalt or concrete), or grooves for traction, shall be incorporated into the design.
5. Roadways shall conform to the natural landform. Significant alterations to the physical and visual character of a hillside shall be avoided by eliminating large notches in ridgelines and wide straight alignments. Modified or reduced-width road sections and split sections shall be considered in the layout of hillside streets to reduce grading and cuts in topography while allowing access for fire trucks and other emergency vehicles.

3. A “vegetative backdrop” shall be maintained by replanting the site with native trees and/or providing the same vegetation that was removed, consistent with City landscaping standards. As demonstrated in the project plans, the proposed vegetation shall be sized and spaced appropriately to screen structures from the growth of the species at maturity and to preserve the appearance of the natural skyline.
474
Ordinance No. 26-___
4. The surface of graded or disturbed slopes with three feet or greater vertical height shall be protected against damage by erosion through the planting of deep rooted ground cover as demonstrated on the project plans. Slopes exceeding eight feet in vertical height shall be planted with ground cover and a combination of shrubs and trees that have a high "root-to-shoot" ratio. The size of shrubs and trees shall be determined based on the individual project area as deemed appropriate by the department and/or Planning Commission.
5. Jute mesh or an equivalent shall be required when planting occurs between August fifteenth and April fifteenth, and when determined, as necessary, by a soils engineer and/or licensed landscape architect. Jute mesh shall be used in combination with required plantings as outlined in the slope landscaping guidelines available on the City of Murrieta’s website for optimal long-term slope stabilization.
6. Indigenous, native vegetation shall be retained and supplemented within canyons and along natural drainage courses where grading does not occur, provided that it conforms with fuel modification and tire prevention plans.
7. Common open space areas, front, and side yards adjacent to a street shall be landscaped and irrigated consistent with City landscaping and fire protection standards. These areas shall be provided with native plant materials that blend with the natural character of the surrounding landscape.
8. In order to protect slopes from soil erosion and failure, and to facilitate revegetation, and automatic irrigation system shall be installed on slopes with planting. Design and operation of the irrigation system shall respect the special conditions that exist in hillside situations specific to maintaining slope stabilization and integrity. In all cases, the emphasis shall be toward using plant materials that may eventually not need to be irrigated; therefore, temporary irrigation systems may be used as approved by the City’s landscape architect and City Engineer. Water and energy conservation techniques shall be utilized (e.g. drip irrigation, alluvial rockscape, etc.). Where irrigation systems are installed above ground, ultraviolet light-resistant brown line, or other approved color, shall be used.
9. A permanent fuel modification area shall be required around projects that are located within high or very-high fire severity zone, adjacent to a high or very-high fire severity zone, or exposed to hazardous fire areas for the purpose of fire protection. The fuel modification area shall be maintained by its owners, a homeowners' association, or other public nonprofit agency, or conveyed within a public easement.
Adequate provisions shall be made for the continual maintenance of these areas, and the fire code official may require brush, vegetation, combustible item(s), or debris to be removed, cleared, and maintained, consistent with the provisions of Chapter 8.32 of the Municipal Code. Where feasible, fuel modification areas shall be designated as common open space rather than private open space. The recommended width of the fuel modification area shall be based on applicable building and fire codes and the recommendations of the fire code official with consideration given to:
a. A worst-case Santa Ana wind condition;
b. The natural ungraded slope of the land within the project and in the areas adjacent to the project; c. Fuel load;
d. All weather access to the project by fire suppression equipment and personnel, access directly to the fuel modified area, and egress out of the project area in case of evacuation; 475
Ordinance No. 26-___
e. The on-site availability of water that can be used for firefighting purposes with regard to fire flows, water pressure, and duration;
f. "Built-in" fire protection within structures (i.e., sprinklers etc.); g. Soil erosion and sediment control measures;
h. The fire department fuel modification policy and the Wild Urban Interface Undesirable Plants & Trees list;
i. Fuel modification zones for landscaping as outlined by the California Department of Forestry and Fire Protection.
10. Fuel modification areas shall also incorporate soil erosion and sediment control measures to alleviate permanent scarring and accelerated erosion.
G. Grading.
1. Grading shall not take place on natural slopes that exceed fifty (50) percent.
2. Slopes created by grading of the site shall not exceed fifty (50) percent or 2:1. Slopes exceeding 2:1 but less than or equal to 1.5:1 may be considered upon additional analysis by a licensed geotechnical engineer. Slopes shall not exceed thirty (30) feet in height between terraces or benches, except that the Planning Commission may permit slopes exceeding these dimensions where the slopes will result in a natural appearance and will not create geological or erosion hazards. The soils report and stabilization study shall be subject to third-party review prior to approval by the City.
3. In order to help address visual impacts at Prominent Ridgelines, the use of the combination of naturally occurring vegetation (trees/shrubs) and proposed landscaping shall be implemented to screen proposed structures at these locations. Alternatively, earth tone colors can be used as a design option if landscape screening is not feasible. Additionally, any required Fuel Modification Zone and California Fire Code standards shall be considered in the design of this screening method, blending with the terrain and existing vegetation.
4. Clearing and/or grubbing, excavation, and other earth disturbances shall not be initiated on hillside areas prior to the issuance of a grading permit, with the exception of county/state authorized soils remediation operations, drill holes, and exploratory trenches for the collection of geologic and soil data or for weed abatement activities. Trenches are to be backfilled and erosion treatment provided where slopes exceed twenty-five (25) percent.
5. Manufactured cut and fill slopes exceeding ten feet in height which would be either exposed to public view, or are adjacent to environmentally sensitive areas, shall be landform or contour graded, where physically feasible, so that their ultimate appearance will resemble a natural slope. This will include slopes adjacent to streets and highways, slopes, adjacent to parks, schools, open spaces, and other public facilities and other prominent slopes.
6. Landform grading shall be used where zero to twenty-five (0-25) percent (non-hillside) slopes intersect with twenty-five to fifty (25-50) percent (hillside) slopes. Proper transitioning from manufactured slopes created by conventional grading methods to natural slopes shall be achieved 476
Ordinance No. 26-___
gradually and naturally through the use of radii or irregular curvilinear shapes that will blend into the adjoining topography tangentially and not create abrupt changes.
7. Fill slopes shall not be placed perpendicularly across a canyon. Straight line cut of fill slopes shall not be made to appear like a dam. The terminus of the fill shall, instead, be concave in shape to restore the canyon appearance. This concave configuration shall be in combination with the use of substantially flatter slope ratios (4:1, 3.5:1, 3: I) at or near the center of this indentation. Symmetrical or unsymmetrical con-cave configurations shall be used depending upon the adjoining or underlying topographic characteristics.
8. Minimal radius rounding at the edges of cut and fill slopes is not an acceptable method.
Transitioning from manufactured slopes to natural slopes shall be achieved gradually and naturally through the use of radii or irregular curvilinear shapes that will blend into the adjoining topography tangentially and not create abrupt changes.
9. In the planning, design, and development of public utilities and infrastructure, every reasonable effort as demonstrated shall be made to minimize grading impacts and incorporates a design that follows the natural contours and character of the land.
10. Side yard slopes and rear yard slopes (less than twenty (20) feet in height) whose view is blocked by future structures need not have landform design applied.
11. Grading shall be phased so that prompt revegetation or construction will control erosion. Where possible, only those areas that will be built on, resurfaced, or landscaped shall be disturbed. Top soil shall be stockpiled during the rough grading phase and utilized on pads or revegetated habitat areas, upon the recommendation of the soils engineer.
12. Applicable requirements of the City and state shall be complied with in conjunction with the latest National Pollution Discharge Elimination System (NPDES) permit prior to the issuance of a grading permit. This may include, but is not limited to, a Grading Plan, and Erosion Control Plan, Best Management Plan (During Construction and Post-Construction Phases) and Construction Monitoring Program.
H. Drainage.
1. Debris basins, energy-dissipating devices, and down drains shall be provided, where necessary, to reduce erosion when grading is undertaken in the hillside areas. Natural drainage courses shall be retained where health and safety can be maintained. Drainage courses retained in a natural state shall be protected from grading activity. In instances where a crossing is required, a natural crossing and bank protection shall be a design option over steel and concrete systems. Where drainage structures are required, they shall be naturalized with coloration, plant materials, native rocks and/or concealment with grading techniques.
2. Drainage channels, slope drainage devices, interceptor drains and terrace drains shall be placed in less visible locations as demonstrated on the project plans and evaluated for erosion. Down drains shall be hidden in swales diagonally or curvilinear across a slope face. In this manner they will be built into the overall landform of the slope. They shall also receive a naturalizing treatment, which may include native rock, colored concrete, and/or landscaping so that the structure appears as an integral part of the environment. In all cases, a concrete liner shall be used in addition to a naturalizing treatment as demonstrated on the project plans and evaluated for erosion. 477
Ordinance No. 26-___
FIGURE 16.24-9
NATURALIZED VERSUS CONVENTIONAL LANDFORMING
3. Cross-lot drainage usage shall be minimized. In situations where this is not possible using conventional design, optional techniques (e.g., single loaded streets, reduced densities, etc.) shall be considered. Use of cross-lot drainage may be considered only after demonstration that this method will not adversely affect the proposed lots or adjacent properties, and that it is required in order to minimize the amount of grading which would result with conventional drainage practices.
4. Where cross lot drainage is utilized, the following shall apply:
a. Project Interiors. One lot may drain across one other lot if a maintenance easement is provided within either an improved, open “V”-swale gutter which has a naturalized appearance, or within a closed drainage pipe that shall be a minimum twelve (12) inches in diameter. This drainage shall be conveyed either to a public street or to a drainage easement. If drainage is conveyed to a private easement, it shall be maintained by its owners or a Homeowners' Association; otherwise, the drainage shall be conveyed to a public easement. The easement width shall be determined on an individual basis and shall be dependent on appropriate hydrologic studies and access requirements. Irrigation lines shall be placed above swales to minimize the impacts in the event of a system failure. When irrigation lines cross an open “V”-swale they shall be placed into a galvanized pipe, which is to be clamped to the soil on both sides of the swale subject to the review of the City Engineer or their designee. b. Project Boundaries. On-site drainage shall be conveyed in an improved open “V”-swale gutter, which has a naturalized appearance, or within an underground pipe in either a private drainage easement, that is to be maintained by its owners or a homeowners' association, or it shall be conveyed in a public easement. The easement width shall be a minimum of ten feet. A greater width may be determined necessary on an individual basis and shall be dependent on appropriate hydrologic studies and access requirements.
I. Public Safety.
478
Ordinance No. 26-___
1. Residential developments shall be constructed in a manner so as to reduce the potential for spread of wildfires as follows:
a. In the case of a conflict where more restrictive provisions are contained in the adopted and/or locally adopted version(s) of the California Building Code or in the California Fire Code, the more restrictive provisions shall apply.
b. Roofs shall be covered with noncombustible materials (e.g., clay tile, concrete shake, tile, or similar materials). Open ends shall be stopped in order to prevent bird nests, or other combustible material, lodging within the roof and to prevent entry of flames. c. Exterior walls and fences shall be surfaced with noncombustible or flame resistive materials.
Alternate surface materials may be approved subject to the approval of the fire code official and building official. Except as otherwise provided herein, exterior walls shall extend to the ground. d. Balconies, patio roofs, eaves and other similar overhangs shall be of noncombustible or flame resistive materials.
e. Plastic webbing, split or whole bamboo, reed or straw-like materials, corrugated plastic or fiberglass materials, and similar flammable materials are not permitted for use on patio covers. f. Vents for attics and underfloor areas shall be designed and located to minimize the likelihood of the spread of fire.
g. Chimneys shall be provided with approved spark arresters.
2. Adequate water supply and pressure for the proposed development shall be required in compliance with the fire department Standards.
3. The fire code official shall require brush, vegetation, or combustible debris to be removed and cleared within ten feet on each side of every roadway and access drive, and may enter upon private property to do so. This requirement shall not apply to single specimens of trees, ornamental shrubbery, or cultivated groundcover provided they do not form a means of readily transmitting fire.
4. If the fire code official determines in a specific case that difficult terrain, danger of erosion, or other unusual circumstances make strict compliance with the clearance of vegetation undesirable or impractical, he or she may suspend enforcement thereof and require reasonable alternative measures designed to advance the purposes of this chapter.
5. Site design shall provide for all-weather equipment access to publicly maintained slope areas for maintenance and emergency purposes. Secondary access shall be provided, or an alternative method may be considered by the fire code official with evidence to ensure public safety.
6. Structures and facilities shall be restricted in geologically hazardous areas.
7. Special construction features shall be required in the design of structures where site investigations confirm potential geologic hazards.
479
Ordinance No. 26-___
8. Development not on public sewers shall be permitted only after site specific investigations have been conducted that demonstrate the soils are suitable for on-site wastewater disposal and the disposal of wastewater will not degrade the subsurface water quality.
9. Due to the hazard associated with saturated soils in areas of steep slopes, irrigation systems in critical areas that have the potential for failure in the judgement of the City Engineer, or their designee, shall be required to be equipped with potentiometers to make sure that the systems will not operate when there is sufficient moisture in the soil.
16.24.070 Hillside Development Guidelines.
The hillside development guidelines are intended to illustrate and amplify the appropriate development concepts for designated hillside areas. The guidelines are not intended to be an exhaustive list of standards, but rather policy statements, to encourage development that is sensitive to the unique characteristics common to hillside properties. The guidelines allow for flexibility and they encourage creativity, especially where a specific plan is prepared. However, the objective development standards provided in Section 16.24.060 shall be considered as a "benchmark" against which hillside development proposals will be reviewed for compliance with the purposes of this chapter.
The guideline's purpose is to allow for innovative or alternate methods of design in hillside areas.
Innovation is encouraged as long as the end result is one that respects the natural character of the hillside and is consistent with the purposes of this chapter and the goals, objectives and policies of the City’s General Plan .
Conformance with the guidelines shall be incorporated in the preparation and approval of subdivisions and individual site developments. During the application review process, the City will evaluate the consistency of the proposal with the purposes of this chapter. Prior to the start of the design effort, it is recommended that the project design team members read the City’s General Plan and become familiar with its policies.
A. Site Design.
1. Design of building sites shall be sensitive to the natural terrain. Structures shall be located in a way that minimizes grading and preserves natural features (e.g., prominent knolls, ridgelines, etc.)
2. Preserve views of significant visual features.
3. Where possible, graded areas should be designed with manufactured slopes located on the uphill side of structures.
480
Ordinance No. 26-___
FIGURE 16.24-10
EXHIBIT 2 - BUILDING PLACEMENT AT A SITE
4. To the extent possible, the width of a building, measured in the direction of the slope, shall be minimized. The degree of the slope will dictate how this is accomplished and shall be demonstrated on the project plans (See Figure 16.24-11 Exhibit 3 – Building Placement at a Site.” 481
Ordinance No. 26-___
FIGURE 16.24-11
EXHIBIT 3 - BUILDING PLACEMENT AT A SITE
5. Clustering of development is encouraged.
B. Driveways and Roadways.
1. Driveways that serve more than one parcel are encouraged as a method of reducing grading, paving, and site disturbance.
FIGURE 16.24-12
ROADWAY PLACEMENT AT A SITE
C. Architecture.
1. The form, mass, and profile of the individual buildings and architectural features shall be designed to blend with the natural terrain and preserve the character and profile of the natural slope.
Techniques to accomplish this include:
a. Detaching the garage from the residence; and
b. Integrating retaining walls into garage walls on sloping lots to reduce gradingand minimize visibility of walls; and
c. Including architectural enrichments and variations in roof massing. Roofs shall incorporate low profiles (for example 3:12 slope) to minimize their visual impact. On sloping land, the roof pitch shall 482
Ordinance No. 26-___
follow the slope of the hillside, instead of being perpendicular to the hillside or opposing hillside slope.
Gable ends shall not be used on downhill elevations. Upper stories shall not be cantilevered out of the opposite direction of the hillside slope.
2. The design of the structure shall give consideration to the lot's size and configuration in order to avoid the appearance of building scale and to minimize the blocking of views as demonstrated on the project plans. For example, within a development, the majority of the units should not be designed with minimum setback to minimum setback. See additional criteria as provided under Section 16.08.030 “Single-family Residential Design Standards and Design Features” and Section 16.08.040 “Multi-family Residential Design Standards”.
D. Walls and Fences.
1. When possible, walls and fences shall be designed as an integral part of the building in order to minimize the visual impact on surrounding areas.
E. Landscaping.
1. Street trees shall be provided in select areas to enhance the natural character of the areas and to create a more rural appearance. Street tree species selection, and spacing of trees, shall be sensitive to the context in which they are planted. Species selection shall be considered to minimize potential impacts to infrastructure improvements (i.e. root damage to streets, sidewalks, etc.).
2. Slopes shall be designed with informal clusters of trees and shrubs to soften and vary the slope planes, consistent with landform grading concepts.
483
Ordinance No. 26-___
FIGURE 16.24-13
BUILDING ENVELOPE ON SLOPE
F. Grading.
There are three distinct types of grading proposed in these guidelines, each with a unique quality, and each with an individual and appropriate application as determined by the City Engineer or designee.
Larger sites will most likely incorporate all three concepts in various parts of the plan.
1. Minimal Grading. This is typically used for large lot single family homes, custom homes with variable foundations that conform to the existing slopes, and other uses that utilize the least amount of grading in order to get the facility and structures built. This technique embraces the following concepts:
a. Grading shall be limited to individual flat graded pad areas for residential building sites.
Grading shall be limited to only the required building areas and adjacent outdoor amenities in steep hillside areas;
b. Foundation systems that require little or no grading are encouraged, forcing the architecture to conform to the land rather than the land to conform to the dwelling; c. Cut and fill lines delineating the grading activity whereby cut areas adjoining next to fill areas shall be situated outside of areas where differential settlement is not desirable (e.g., roadways, building pads, driveways, etc.);
d. The balancing of grading is the concept to minimize the volume of cubic yards of earth excavated and filled.
2. Contour Grading. This concept results in post-development landforms that exhibit many of the characteristics present within natural landforms. Contour grading is typically used in situations where conventional, terraced, grading with benches and slopes might be used but a "softened" grading look is desired. This would be desirable for areas that are limited in public view (i.e. concealed rear yards). 484
Ordinance No. 26-___
Typically, contour grading can reduce required cut and fill volumes as compared with traditional, terraced, grading. The design elements associated with this type of grading include: (See Figure 16.24-14 “Contour Grading”)
a. The use of horizontal and vertical curve variations for slope banks creating a curvilinear pattern; b. Post-development landforms that exhibit natural terrain characteristics (without the heavy modeling effects of landform grading);
c. A general rounding of slopes at slope intersections and transition zones with natural grade; d. Pad configurations that are curvilinear; and
e. Slopes that are designed with contour grading techniques (e.g., the location of slopes behind structure (not in side yards), slopes in hidden locations, or slopes less than ten feet in height).
FIGURE 16.24-14
CONTOUR GRADING
485
Ordinance No. 26-___
FIGURE 16.24-15
LANDFORM GRADING
3. Landform Grading. Graded slopes in this category will replicate the irregular shapes of natural slopes. Landform grading techniques shall be used whenever slopes are created that will be open to public view.
The intent of these grading guidelines is to incorporate the basic principles of the landform grading concept as the preferred method in the design and construction of hillside development projects. (See Figure 16.24-15 “Landform Grading”)
Landform grading techniques shall incorporate the following concepts:
a. Land plans shall flow with the natural topography rather than against it. This means that street patterns and building pad configurations shall follow the underlying topographic features rather than cutting across them;
b. Landform graded slopes are characterized by continuous series of concave and convex forms interspersed with mounds that blend into profiles with varying slope gradients and with significant transition zones between man-made and natural slopes;
c. Slope drainage devices either follow natural lines of the slopes or are tucked away in special Swale and berm combinations in order to conceal the drains from view. Exposed segments in visible areas are treated with natural rock for a more aesthetically pleasing appearance; d. This technique shall be used wherever possible to provide for a variety of slope percentage, slope direction, and topographical detailing in a three-dimensional, undulating pattern similar to existing terrain; and
486
Ordinance No. 26-___
e. Manufactured cut and fill slopes in excess of ten feet in height that will be either exposed to permanent public view or are adjacent to environmentally sensitive areas, shall be designed with features characteristic of natural slopes. This design shall be implemented, as determined by the City Engineer based on the project plans so that the ultimate appearance will resemble a natural slope. This is applicable to, but not limited to, slopes along streets, highways, adjacent to parks, schools, open spaces, other public facilities, and other prominent and visible slopes.
4. The following grading guidelines and techniques serve to implement preferred landform grading techniques and help avoid unnecessary cut and fill:
a. Cuts. When grading into convex landforms (i.e., outward-projecting features), the resulting cuts shall maintain a similarly projecting form and be contoured to blend seamlessly with the undisturbed portions, thereby preserving a natural-appearing landform. b. Use of variable slope ratios. Because landform grading designs require the use of variable slope ratios, this may result in loss of usable area near building pads. Therefore, only cut slopes may be steeper than 2:1, but not steeper than 1.5:1 and shall meet the following guidelines:
1) A geotechnical engineer shall certify that slopes will meet standard stability requirements; 2) A licensed landscape architect shall certify the plantability of the slopes, with an emphasis on the slopes steeper than 2:1; and
3) The overall ratio from top to toe will be 2:1 or flatter; and 4) Ratios flatter than 2:1 will also be used in the slope design. c. Grading operations shall occur to avoid the rainy season, October fifteenth (15th) to April fifteenth (15th). Grading permits shall only be issued when a plan for erosion and sediment control has been approved by the City without regard to time of year. Additionally, those projects also requiring a Storm Water Pollution Prevention Plan (SWPPP) shall obtain approval of the SWPPP prior to any grading permit issuance.
d. Rounded and smooth transitions shall occur where man-made and natural slopes intersect.
Where cut or fill conditions are created, slopes shall be varied. The angle of a graded slope shall be gradually adjusted to the angle of the natural terrain. e. Manufactured slopes adjacent to roadways shall be consistent with the landform grading and revegetation techniques.
f. Slopes shall implement drainage measures as detailed within Sub-article 11 of the City of Murrieta Grading Manual.
G. Drainage.
1. Natural drainage courses shall be preserved and enhanced to the maximum extent per the associated National Pollution Discharge Elimination System (NPDES) permit associated with the project site.
487
Ordinance No. 26-___
2. The NPDES Permit also requires that a project’s stormwater runoff be retained on-site through filtration to the maximum extent permitted by State law. Runoff not retained on-site shall be conveyed off-site in accordance with City standards, codes, and policies.
16.24.080 Exceptions.
A. Residential Accessory Structures and Accessory Dwelling Units. This Chapter shall not apply to the development of residential accessory structures and accessory dwelling units on parcels with existing development approvals when the new construction:
1. Does not require the use of a retaining wall; and
2. Meets the criteria as described within Section 16.44.150 (Residential Accessory Uses and Structures) and Section 16.44.160 (Accessory Dwelling Units) and Section 16.02.020 (Exemptions from Land Use Permit Requirements).

WHEREAS, on January 25th, 2023, the City held a second public workshop at its Planning Commission meeting to provide and receive input from local residents and the Commission concerning hillside development standards in the City. Areas that were covered were inclusive of existing and proposed Hillside Overlay applicability, height allowances for structures, height measurement criteria, hillside slope applicability, average slope calculation, Prominent Ridgeline Overlay, and retaining wall criteria. The other items presented by staff were potential techniques to improve the readability of the existing Murrieta Municipal Code (MMC), examples of graphic exhibits that could be incorporated, highlights of areas to resolve code inconsistencies, ways to incorporate best practices, and suggestions from staff on how to simplify the standards to make them more user-friendly to both staff and applicants; and WHEREAS, on April 11th, 2023, staff hosted a presentation on the existing and proposed hillside standards. Staff held the workshop to obtain additional feedback from the community on the proposed hillside development standards. This additional outreach was conducted per direction from the prior Planning Commission for further community input and to provide transparency. Areas that were covered were inclusive of existing and proposed Hillside Overlay applicability, height allowances for structures, height measurement criteria, hillside slope applicability, average slope calculation, Prominent Ridgeline Overlay, and retaining wall criteria. There was time provided for questions/answers at the end of the presentation for feedback on the proposed updates from the public; and
WHEREAS, on June 28th, 2023, the City of Murrieta Planning Commission held a duly noticed public hearing on the proposed Development Code Amendment, at which the staff report was presented as well as written comments from the public regarding the need for the proposed code amendment and providing evidence in the record to support the findings required by the Murrieta Development Code Section 16.58.080; and
WHEREAS, on August 15, 2023, the City Council hosted its first workshop on this item.
The City Council requested additional information. Council members and staff discussed key standards for retaining wall heights, specifically discussing a 6-foot baseline and the balance between aesthetic landscaping and mandatory fire safety fuel modification zones. The session aimed to replace subjective guidelines with objective criteria for building on slopes, ensuring that new developments preserve the city’s visual ridgelines while providing a clearer, more predictable path for project approvals. The workshop was continued to a future meeting date; and WHEREAS, on March 5, 2024, the City Council hosted a second workshop on this item.
The discussion centered on a potential review process for retaining walls, clarifying building 495
Ordinance No. 26-___
height measurements on sloped terrain, and ensuring the "Hillside Overlay" maps accurately reflect local topography to avoid unnecessary burdens on flat-land homeowners. Crucially, the Council worked to harmonize aesthetic screening requirements with mandatory state fire safety and fuel modification mandates, prioritizing the protection of prominent ridgelines while ensuring the code aligns with current California law. Due to additional time needed for the discussion and feedback, the workshop was continued for a second time; and WHEREAS, on June 17, 2025, the City Council hosted a third workshop on this item. The direction/feedback from the Council was that detailed examples of standards from other localities and more of them were needed in order to assist the Council with moving forward; and WHEREAS, on October 21, 2025, the City Council held its fourth workshop on this item. The discussion centered on the following areas, where the Council reached consensus on key Focus Topics with the Applicability of Standards; Identifying The City’s Hillside Areas: 20 Percent Slope Versus 25 Percent; 25 Percent Slope Criteria; Specific Plans; and the use of Geographic Info. Systems (GIS) And Average Slope Formula; and WHEREAS, on November 18, 2025, the City Council conducted its fifth workshop on this item, during which several key policy directions and considerations were identified, including, but not limited to, the following: that updates to retaining wall regulations should be addressed on a citywide basis rather than limited to Hillside Areas; that standards should provide both flexibility through defined options and sufficient specificity, particularly with respect to retaining wall design; that retaining wall design standards should be implemented citywide; that color palettes for retaining walls should generally consist of muted tones, with specific shades or blends established in advance to ensure a consistent and desirable aesthetic; that earthtone colors may be appropriate for hillside structures; that retaining walls exceeding six feet in height may, in certain circumstances, be excessive on a citywide basis; that tiered retaining walls incorporating landscaping are a preferred design feature; that Keystone-style walls with integrated landscaping are also desirable; that landscaping is a priority consideration for the Council, including the establishment of larger plant sizes earlier in the development process; that additional clarification from the Fire Department is necessary regarding planting requirements within Fuel Modification Plans; and that distinctions between rural residential and tract home front-yard setbacks should be more clearly defined; and, WHEREAS, on February 3, 2026, the City Council held its sixth and final workshop on the topic. The Murrieta City Council discussed key topics, including retaining walls, landscaping standards, fire severity zones, distinctions between developed and undeveloped properties, and the relationship between hillside and citywide standards. Public input raised concerns about the visual and regulatory impacts of retaining walls, tree removal credits, definitions of undisturbed land, conditions of approval, and broader issues such as Senate Bill 9 and insurance implications.
Following that discussion, the Council reached consensus to provide direction on specific retaining wall types (including geogrid, CMU, and keystone walls) for hillside areas, suggested requiring earlier installation of larger landscaping, and that a separate ordinance was needed on a city-wide basis as it relates to retaining walls, along with direction to staff that the definitions of developed and undeveloped land for hillside areas need to be clearly defined. 496

SECTION 4. Section 16.18.080 (Height Measurement and Height Limit Exceptions) of the Murrieta Municipal Code is hereby amended in its entirety to read as follows:
“All structures shall meet the following standards relating to height, except for fences and walls, which shall comply with Chapter 16.22 (Fences, Hedges, and Walls).
A. Maximum Height. The height of structures shall not exceed the standard established by the applicable zoning district in Article II (Zoning Districts and Allowable Land Uses) or for structures within a Hillside Area under Section 16.24.020.A. In addition, the maximum height for structures on a specific parcel shall be measured as follows:
1. Establishing the high point and low point on the property as reference grade points as follows:
a. A measurement is taken from the lower of existing or proposed grade, 5 feet away from the lowest grade point around the structure in accordance with Figure 16.18-1. This point shall be the low reference grade point. The highest point anywhere on the structure may not exceed the elevation of that low grade point by more than the allowable height plus the grade differential between the low point of structure and high point of structure (excluding items as detailed under Section 16.18.080(B) (Exceptions to Height Limits)), but in such case where the actual grade differential exceeds 10 feet, only a maximum of 10 feet may be added to the maximum allowable height per the zone. The measurement is the difference in elevation between the highest and the lowest adjacent ground elevation surrounding the building.
FIGURE 16.18-1
MEASUREMENT LOCATIONS
b. If the difference in elevation is 10 feet or less, the reference grade point is established at the highest adjacent ground elevation. See Figure 16.18-2. If the difference in elevation is greater than 10 feet, the reference grade point is established at 10 feet above the lowest adjacent ground elevation. See Figure 16.18-3. For stepped or terraced buildings, the building height is the overall height as illustrated in Figures 16.18-4 and Figure 16.18-5.

1. Roof-mounted Features. Roof-mounted features including chimneys, cupolas, clock towers, elevator equipment rooms, equipment enclosures, and similar architectural features shall be allowed, up to a maximum of fifteen (15) feet above the allowed structure height. The total square footage of all structures above the heights allowed in the zoning districts shall not occupy more than twenty-five (25) percent of the total roof area of the structure. Greater height or area coverage may be allowed subject to the approval of a minor conditional use permit in compliance with Chapter 16.52.
2. Parapet Walls. Fire or parapet walls may extend up to four feet above the allowable height limit of the structure.
3. Public Assembly, Hotels, Class "A" Office and Public Structures. Places of public assembly including churches, schools, assembly halls, Class "A" office buildings greater than three (3) stories, hotels and other similar structures may exceed the established height limit by one (1) foot for every two (2) feet that the minimum required front, rear and side yard setbacks are increased. The increase in the front, rear and side yard setbacks is determined by averaging the total of the increased building setbacks at the closest point on all sides. The maximum additional height allowed is thirty (30) feet above the height limit established for the applicable zoning district. This exception shall not apply when the site is adjacent to single-family zoned property. This exception may be used in conjunction with the height exception for rooftop equipment.
4. Telecommunications Facilities. Telecommunication facilities, including antennae, poles, towers, and necessary mechanical appurtenances, may be authorized to exceed the height limit established for the applicable zoning district, subject to the approval of a conditional use permit in compliance with Chapter
16.52. 5. Basement. A basement is defined as a story that has its floor surface below the adjoining finished grade as both conditioned and unconditioned space per the California Building and Residential Codes.” SECTION 5. Section 16.22.050 (Measurement of Fence or Wall Height) of the Murrieta Municipal Code is hereby amended in its entirety to read as follows:
“16.22.050 Measurement of Fence or Wall Height.
Where there is a difference in the ground level between two adjacent parcels, the height of a fence or wall constructed along the property line shall be determined by using the finish grade of the highest contiguous parcel.”

B. Where a BP or IG zoning district abuts another zoning district, a solid masonry wall six feet in height shall be constructed on the zone boundary line;
C. Walls shall be of solid masonry construction and shall be of a decorative design when in view of public rights-of-way subject to approval of the director; and 505
Ordinance No. 26-___
D. The director may waive or modify requirements for walls between different zoning districts where a solid masonry wall already exists on the contiguous property if the following findings can be made:
1. The existing wall meets or can be modified to conform to the intent of this chapter;
2. Suitable landscaping can be installed adjacent to the existing wall to supplement and enhance the desired physical separation;
3. The existing wall can be protected to prevent vehicle damage, if necessary, and
4. Concurrence of the adjacent property owner can be obtained, to modify the existing wall to meet the requirements of this chapter.”
SECTION 7. Chapter 16.24 (Hillside Development) is hereby amended in its entirety to read as follows:
“16.24.010 Purpose.
The purpose of this chapter is to provide regulations for the development of areas in the City that, because of their topography, require special consideration to ensure that they are developed in a way that substantially maintains their natural character and environmental and aesthetic values to implement the City’s General Plan, and to provide for the safety, health, and welfare of the public by:
A. Providing guidelines and standards for development in visually sensitive Hillside Areas to minimize the adverse impacts of grading and to promote the goals and objectives of the City’s General Plan;
B. Maintaining an environmental equilibrium consistent with existing vegetation, wildlife, soils, geology, slopes, and drainage patterns, and to preserve natural topography and scenic character, including canyons, creeks, knolls, rock outcrops, and ridgelines whenever feasible; 506
Ordinance No. 26-___
C. Reasonably consider development proposals that feature water conservation and aquifer recharge techniques;
D. Reasonably consider development proposals that are sensitive to fire, flood, slide, erosion, pollution, or other safety hazards;
E. Reasonably consider sensitive development through flexible design and innovative arrangement of building sites by utilizing variable lot sizes, clustering, and setback variations; F. Utilizing nontraditional design standards for streets and hillside grading where development quality and public safety are not affected;
G. Reasonably consider developments that incorporate desirable existing features of land (e.g., natural vegetation, viewsheds, topographic features);
H. Protecting significant natural areas for ecologic purposes, educational, and other scientific study purposes; 1. Encouraging the use of drought-tolerant plant material to protect slopes from soil erosion and slippage, preserve natural watershed, minimize fire hazard, and minimize the scarring and deformation of the natural landscape;
I. Limiting the impact of cut slopes on adjacent developed and undeveloped properties; and J. Providing for appropriate intensity of development (e.g., density, massing, etc.) through a variety of design techniques to ensure that development intensity decreases as slopes become steeper (e.g., lot sizes appropriate for steeper topography and separation of structures sufficient to preserve a viewshed).
16.24.020 Applicability.
A. Location Consideration for Analysis. Notwithstanding any other provisions of this Code, the standards contained in this chapter apply to uses and structures within Hillside Areas that have a slope twenty-five (25) percent or greater and as designated within the boundaries of a Hillside Overlay Map.

Ordinance No. 26-___
Grading. To bring an existing surface to a designed form by excavating, filling, or landforming operations.
Contour Grading. A grading concept designed to result in earth shaping that resembles natural terrain characteristics.
Conventional Grading. A grading concept that results in simple, straight forward, cut and fill lines and even slopes.
Landform Grading. A grading method that replicates the irregular shapes of the natural ground surface.
Landform graded land surfaces are characterized by continuous series of concave and convex forms interspersed with mounds that blend into profiles, nonlinearity in plan view, varying slope gradients, and significant transition zones, between man-made and natural land surfaces.
Hillside Area. Means those areas specifically designated on a Hillside Overlay Map as adopted by the City Council under Section 16.24.100.
Mass Grading. The movement of large quantities of earth over large areas. Disruption of the majority of the on-site surface terrain resulting in a successive pad/terrace configuration.
Minimal Grading. A grading concept designed to minimize excavation and filling. Allows the movement of earth for projects (e.g., as individual building foundations, driveways, local roads, and utility excavation). The concept is associated with roads conforming closely to natural contours and with structures being built on natural terrain.
Pad. A level area created by grading to accommodate development.
Prominent Ridge. A ridge or hill location that is visible from Interstate 15, Interstate 215, or from an arterial or secondary street, that forms part of the skyline or is seen as a distinct edge against a backdrop of land.
Ridge. An extended, narrow, conspicuous elevation of land generally between valleys.
Slope. An inclined ground surface, the inclination of which is expressed as a ratio of the vertical distance (rise), or change in elevation, to the horizontal distance (run). The percent of a given slope is determined by dividing the rise by the run, multiplied by one hundred (100).
Undeveloped. Means land within a hillside area that remains in a substantially natural state and has not been significantly altered by grading, construction, paving, or installation of infrastructure improvements. 512
Ordinance No. 26-___
Slope, Man-made. A manufactured slope consisting wholly or partially of either cut or filled material.
Slope, Natural. A slope that is not man-made.
Slope, Natural. A slope that is not man-made that exceeds twenty-five (25) percent.
Slope Ratio. The relationship of a slope's horizontal length to vertical height, with the height specified as one (e.g. 2:1).
Slope Transition. The area where a slope plane changes to meet the natural terrain or a level graded area either vertically or horizontally.
16.24.040 Application Submittal Requirements.
Applications for development shall comply with the submittal requirements of this chapter. When a development project is a specific plan or master development plan, the submittal requirements shall be incorporated in the appropriate sections of the corresponding documents. If adequate detailed studies are provided with the specific plan and/or master development plan, subsequent implementing development applications shall be reviewed for substantial conformance with these plans.
Application filing requirements are as follows:
A. Natural Features Map. This map shall identify slope banks, ridgelines, canyons, natural drainage courses, United States Geological Survey (U.S.G.S.) blueline streams, rock outcroppings, sensitive biological habitats, cultural resources, and other natural features for the purposes of project review and California Environmental Quality Act (CEQA) analysis.
513
Ordinance No. 26-___
B. Overall Conceptual Grading Plan. An overall conceptual grading plan shall be submitted at a minimum scale of one (1) inch equals twenty (20) feet). The plan shall include the following items:
1. A legend with symbols identifying the following, but not limited to: high point, low point, spot elevations, pad, top of wall, top of footing, top of curb, top of ground surface on both sides of a retaining wall, and planned drainage improvements;
2. A separate map shall be provided with proposed cut and fill areas, depths of these identified areas shown in five-foot topographic lines. Quantities of each cut and fill area shall be identified and calculated as a percentage of the total site area. The cut and fill areas shall be either colored green and red, crosshatched, or screened to delineate each respective area;
3. Contours for existing and proposed topographic conditions shall be provided within submitted plan exhibits. Existing contours shall be depicted with continuous screened lines and proposed contours shall be depicted as above except with a solid line. Contours shall be shown at minimum intervals of two feet of change in elevation. Elevations of less than two feet shall be depicted with spot elevations; and
4. Additional information as required to assist with review of the project.
C. Drainage Map. A conceptual drainage and flood control facilities map describing planned drainage improvements. The map shall utilize City standards or an acceptable alternate as determined by the City Engineer or their designee.
D. Slope Profile Drawings. Cross-section slope profiles shall be included with the slope analysis.
Additional profiles may be required as determined by the City Engineer or their designee. The slope profiles shall:
1. Be drawn at the same scale and indexed, or keyed, to the slope analysis map, grading plan, and project site map. Both vertical and horizontal scales shall be indicated;
2. Show existing and proposed topography, structures, and infrastructure. Proposed topography, structures, and infrastructures shall be drawn with a thin, solid line. Existing topography and features shall be drawn with a dashed line;
3. Extend at a minimum of one hundred (100) feet outside the project site boundary to clearly show the impact on adjacent property. Additional distance may be necessary to determine off-site terrain and features;
4. Be drawn along those portions of the subject site where:
a. The greatest portion of the site where alteration of existing topography is proposed; b. The most intensive or massive portion of the site where development is proposed (e.g. where structures are proposed);
c. Where proposed grading would potentially impact existing natural drainage conditions. 514
Ordinance No. 26-___
5. At least two of the slope profiles shall be roughly parallel to each other and roughly perpendicular to existing contour lines. At least one other slope profile shall be roughly at a ninety (90) degree angle to the other slope profiles and existing contour lines.
F. Indicate Source of Data. Indicate the datum, source, data, and scale.
G. Geotechnical Report. A geotechnical and soils report shall be prepared by a registered geotechnical engineer to City standards and provide in sufficient detail to substantiate and support the design concepts presented in the application. Additional environmental technical studies and investigations, including, but not limited to, hydrologic, seismic, access/circulation, cultural, tribal cultural, and biological resources may be required to help in the determination of the buildable area of a subject site for consistency with project review and for California Environmental Quality Act (CEQA) analysis.
H. Objective Design Guidelines. Objective design guidelines shall be provided for projects that are to be reviewed by the Planning Commission. Otherwise, illustrative building elevations showing all sides of the structure shall be provided.
I. No Grading Proposed. See 16.24.080 (Exceptions) for applicability.
