Subject: COMMENTS ON DRAFT CITY OF DEL MAR SAFETY ELEMENT AS
THEY RELATE TO BLUFF-FRONTING PROPERTIES ABOVE NORTH
BEACH IN THE CITY OF DEL MAR AND IMMEDIATELY ADJACENT
TO DEVELOPED PROPERTIES IN THE CITY OF SOLANA BEACH
Dear Ms. Whalen, Ms. Lazier, and Mr. El Khourey:
In accordance with your request, we have reviewed the draft City of Del Mar Safety Element dated December 2025. This document has been recommended for adoption by the City Planning Commission and is targeted for consideration by the City Council this spring.
The purpose of our review was to summarize selected portions of the Safety Element and provide a professional opinion and general comments regarding its applicability to the geotechnical aspects of the bluff-fronting properties above North Beach in the City of Del Mar. These properties are immediately south of extensive residential development that continues north in the City of Solana Beach. The parcels studied are predominantly vacant and intended for residential use, with one parcel developed with a single-family residence (Parcels). The Parcels are identified as the following:
APNs 298-241-34 & 298-241-35
APNs 298-241-06, 298-241-07 (929 Border Avenue) & 299-030-14 APN 299-030-15 (101 Border Avenue)
Specifically, our comments focus on the Coastal Hazards, Vulnerability, and Risk Assessment (CHVRA) section of the draft Safety Element as they apply to the North Bluff properties and the recommended building setback presented in Geocon’s geotechnical reports dated September 6, 2019, and March 29, 2023. Additional information is also provided to explain the geologic differences between the bluffs along North Beach (North Bluff) and South Beach (South Bluff) generally located between Powerhouse Park south to the Los Peñasquitos inlet.
In summary, the City is scientifically mistakenly associating the North Bluff properties with CoSMoS Phase 1 data in the City’s draft Safety Element in lieu of relying upon site-specific geologic and May 19, 2026 Item 8
- 2 - February 18, 2026
geotechnical investigations for this area that the City has in its public records for several years. This work includes the site-specific building setback to be applied to future North Bluff development based on an 87-year record of bluff erosion as well as subsurface geotechnical investigations and engineering analysis in this area conducted by Geocon. These studies should remain the primary basis for setback determination and development planning for all North Bluff properties as the primary factor controlling sea cliff erosion in this area is the overall relative strength of the geologic units as evidenced in the peer-reviewed, published geologic literature.
BACKGROUND
The Safety Element is a state-mandated component of the City of Del Mar’s Community Plan (General Plan) that identifies natural and anthropogenic hazards with the potential to affect the City over both short- and long-term timeframes. Its purpose is to establish a policy framework to help the City anticipate and plan for these hazards. The overarching goal is to reduce the community’s exposure to risks associated with fires, floods, droughts, earthquakes, landslides, climate change, and other hazards that may result in life-threatening injuries, property damage, and economic or social disruption. The Safety Element also serves as the basis for adaptation planning.
The Safety Element is one of seven required elements of the City’s General Plan. With respect to community development, it works in conjunction with the Land Use Element, which establishes the location, type, intensity, and distribution of land uses throughout the City and defines land use buildout potential. This includes identifying areas designated for residential, commercial, office, open space, and building-restricted uses, particularly in areas subject to natural hazards.
A section of the draft Safety Element refers to a Coastal Hazards, Vulnerability, and Risk Assessment (CHVRA), which evaluates the City’s vulnerability to coastal hazards. The City prepared the CHVRA in 2016, followed by a supplemental addendum in 2018, which included the preparation and approval of an Adaptation Plan. These assessments evaluated the projected timing and extent of vulnerability affecting City beaches, lagoons, coastal bluffs, visitor-serving amenities, public access areas, residential and commercial development, and public infrastructure. The findings have been used by the City to guide local planning efforts aimed at adaptation, risk minimization, and future response to projected hazards such as sea level rise, flooding, and erosion.
Past City Council Action to Protect the Private Property Interests of its Residents The CHVRA, which is comprised of the 2016 vulnerability study and 2018 addendum, as well as the City’s Adaptation Plan are locally adopted documents and not a part of the City’s certified Local Coastal Program (LCP). While once considered for incorporation into its LCP, in June 2021, the City Council voted to formally withdraw an LCP amendment just prior to the California Coastal Commission’s (CCC) consideration. The withdrawal was based on the City’s acceptance of several policy changes requested by the CCC including a provision for managed retreat (relocating homes) to address hazards associated with rising sea levels. The City disagreed with the CCC’s requests and determined they were not in the best interest of the City. As stated in the City’s letter to the CCC, “The Coastal Commission’s modifications reintroducing managed retreat for private property would irreversibly harm Del Mar, Del Mar beaches, the millions of beach visitors each year, and the 700+ homes in the beach community.
The modifications also include new deed restriction and altered bluff erosion rate calculation requirements for Coastal Bluff Overlay Zone with potential to further apply to another 500+ homes on May 19, 2026 Item 8

the South Bluff.”1 By withdrawing the LCP amendment, the City’s LCP does not have provisions for long-term adaptation policies to address coastal hazards along its shoreline or to protect the rights of the public and private property owners.
COASTAL HAZARDS, VULNERABILITY AND RISK ASSESSMENT and CoSMoS The 2018 CHVRA addendum compared the 2016 CHVRA assessments of beach erosion, bluff erosion, and coastal flood risk with results from the U.S. Geological Survey’s Coastal Storm Modeling System (CoSMoS 3.0 Phase 2, USGS 2017) and the Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS) and Flood Insurance Rate Maps (FIRM).
The addendum concluded that: (1) the CHVRA and CoSMoS flood hazard projections, both of which account for sea level rise, are generally consistent and appropriate for adaptation planning and coastal policy development; and (2) the CHVRA shoreline and bluff erosion projections are appropriate for adaptation planning and coastal policy development. Although CoSMoS Phase 2 bluff erosion projections indicate less erosion than the previous CoSMoS Phase 1 data (2016 study), the CHVRA bluff erosion projections (based on CoSMoS Phase 1), which were relied upon for the adopted Adaptation Plan, were deemed appropriate for the purposes of adaptation planning and coastal policy development “to ensure the City is not relying on an under-prediction of future bluff erosion.” However, contrary to the implication of this statement, use of CoSMoS Phase 1 projections for planning purposes is not merely a “conservative” option but an erroneous and scientifically unsubstantiated choice to use given that it is outdated and is based on unrealistic computer modeling, instead of current science as represented by the CoSMoS Phase 2 projections. Moreover, generalized, computer generated modeling projections are not a substitute for actual site-specific geotechnical investigation based on actual, local geology and structural characteristics, which is the most appropriate mechanism for determining appropriate and scientifically defensible site development parameters. In this instance, with respect to the North Bluff properties, site-specific geotechnical investigations have been completed (as discussed below) that represent the best available science as to those properties and the most appropriate planning mechanism for purposes of the Safety Element update as well as future development.
CoSMoS Phases 1 and 2 and Limitations
The Coastal Storm Modeling System (CoSMoS Phases 1 and 2) is a regional guidance tool developed by the U.S. Geological Survey to predict storm-induced coastal flooding, erosion, and cliff failures, and the authors of CoSMoS have made it well known in their published warnings and disclosures that CoSMoS is not intended for site-specific prediction of future bluff retreat and land use development.
Rather, it is intended to assist coastal planners in enhancing public safety and managing coastal resources in a very generalized way. Its primary purpose is hazard screening and regional planning.
CoSMoS Phase 1, used in the City’s 2016 CHVRA study, provides regional-scale assessments over broad coastal areas using lower-resolution data and generalized assumptions regarding coastal morphology (as opposed to site-specific geologic and geotechnical data considering the actual strength 1 June 8, 2021 Letter to CCC: https://www.delmar.ca.us/DocumentCenter/View/7622/City-of-Del-Mar-Notice-of-Withdrawal-of-SLRLCPA-682021#:~:text=Approved%20by%20City%20Council%20on,during%20the%20City%20Council%20direction:

and structural characteristics of the localized sea cliffs). Regional erosion rates presented in the document National Assessment of Shoreline Change, Part 4: Historical Coastal Cliff Retreat along the California Coast, U.S. Geological Survey Open-File Report 2007-1133 (Hapke & Reid, 2007) were used as the basis for the future cliff projections.
CoSMoS Phase 2 builds upon Phase 1 by incorporating higher-resolution nearshore data, improved wave transformation and runup calculations, and more refined representations of coastal processes such as wave-driven erosion, cliff failure, and beach-bluff interactions. Phase 2 is better suited for localized risk assessments and adaptation planning; however, it still does not replace site-specific geotechnical or engineering analyses because it does not incorporate or rely on actual site-specific geologic and geotechnical data concerning the actual strength and structural characteristics of the localized sea cliffs.
Although CoSMoS Phase 2 was better suited for localized risk assessment, it was not recommended for adoption as the primary policy to avoid revising previously adopted conservative erosion assumptions downward, as noted above. Modeled storm-driven erosion rates were used in the Phase 2 analysis in lieu of averaged low resolution measured historical retreat rates in Phase 1 largely derived from regional historic shoreline datasets (Hapke & Reid). Figure 1 (attached), from the CHVRA, presents a comparison of projected bluff-top positions from CoSMoS 3.0 Phase 1 and Phase 2 along North Beach, Del Mar, under various sea level rise scenarios.
These modeling tools are appropriate for screening-level analyses because they rely on overly generalized assumptions regarding bluff geometry, soil and bedrock properties, groundwater conditions, and erosion processes which are suitable for regional-level evaluation. Such assumptions cannot adequately represent localized conditions that control site-specific bluff failure mechanisms.
A proper, industry-standard, and legally defensible geotechnical investigation directly evaluates sitespecific conditions through direct measurements of bluff retreat rates from historical aerial photographs, field mapping, subsurface exploration, laboratory testing and engineering analysis to identify actual failure mechanisms, and risks. Accordingly, site-specific geotechnical studies provide the most reliable basis for setback and stability determinations, while CoSMoS outputs are best considered as background information rather than substitutes for site-specific analysis in development review.
As indicated above, the authors of Open-File Report 2007-1133 and CoSMoS provide several disclaimers, including the following:
“Rates of change are being published for the purpose of regional characterization. The results and products prepared by USGS are not intended for comprehensive, detailed site-specific analysis of cliff retreat” (Hapke & Reid).
"The results and products prepared by the USGS are not intended for comprehensive detailed site-specific analysis of cliff retreat, nor are they intended to replace any official sources of cliff erosion information identified by local or state government agencies, or other federal entities that are used for regulatory purposes. Retreat rates presented herein may differ from other published rates, and differences do not necessarily indicate that the other rates are inaccurate.
May 19, 2026 Item 8
- 5 - February 18, 2026
Some discrepancies are expected, considering the many possible ways of determining cliff edge positions and rates of change, and the inherent uncertainty in calculating these rates. Rates presented in this report represent cliff retreat under past conditions. The results are not intended for predicting future cliff edge positions or future rates of cliff retreat” (Hapke & Reid). "This interactive mapping tool, including its data (tool and data) are provided for informational purposes. The tool and data are not for the purpose of providing advice or guidance on issues or activities related to its content including, but not limited to navigation, investment, development or permitting." CoSMoS Phase 1 – Cliffs Mapping Tool webpage. "The CoSMoS cliff projections are large-scale, long-term estimates of cliff behavior. They project the long-term rate that results from multiple cliff failures accumulating through time, rather than the exact timing of individual cliff failure events. If you're looking at 1) short-term site-specific behavior, as in "how soon is this cliff likely to fail", or 2) how a site-specific crossshore cliff profile might evolve through time, CoSMoS cliffs are probably not the right tool and should be supplemented by local, more technically detailed investigations." CoSMoS Phase 1 – Cliffs Mapping Tool webpage.
“CoSMoS was not developed to support site-specific engineering projects (e.g., site design) and is not necessarily compatible with engineering design codes and guidance. CoSMoS was designed to assess community-scale vulnerabilities and for broadly identifying where more detailed geo-technical engineering studies may be required” USGS CoSMoS 3.0 Frequently Asked Questions (Southern California Region).
SITE-SPECIFIC GEOTECHNICAL STUDY
Geocon performed comprehensive site-specific geotechnical investigations of the properties above North Beach between 2016 and 2019, with updates completed in 2023. These site-specific investigations included excavating 43 borings and trenches, performing 160 laboratory tests, conducting detailed bluff-face mapping, development of 25 geologic cross-sections, and slope stability analyses evaluating both static and seismic conditions. This work, combined with analyses of historical and future predicted erosion rates considering sea level rise, formed the technical basis for recommending a conservative project setback in accordance with accepted standards of practice and CCC sea level rise guidance.
To evaluate historic bluff retreat, a high precision orthophotograph was produced from a commissioned aerial survey conducted in 2019, supplemented by historical aerial photographs from 1932 and 1953. This provided an 87-year analysis period, compared to the 65-year timeframe used in CoSMoS Phase 1 which their time span ended in 2000. A photogrammetrist geo-referenced the historical imagery used by Geocon to ensure accuracy. Geocon’s analysis utilized 66 measurement stations at 20-foot intervals, compared to 4 low-resolution data points spaced approximately 300 feet apart along North Bluff in the CoSMoS Phase 1 study. Geocon’s historical rate calculation combined with the predicted future erosion rate over the life of the project, considering sea level rise incorporated into the slope stability analysis, supported the recommended building setback line. Figure 2, attached, presents the recommended building setback line based on Geocon’s site-specific study as well as the 2.0m SLR future cliff retreat positions published in CoSMoS 3.0, Phase 1 and Phase 2.
May 19, 2026 Item 8

LiDAR
Policy 5.8 of the draft Safety Element calls for coordination with the Scripps Institution of Oceanography (SIO) to obtain monitoring data related to ocean conditions and beach and bluff erosion to “inform plans for avoidance and minimization of shoreline hazards.” Scientists from SIO have been performing direct, high-resolution monitoring of the South Bluff portion of the Del Mar bluffs for roughly 25 years using LiDAR (Light Detection and Ranging) to measure erosion and cliff change.
Early datasets were episodic and not uniform in resolution using airborne LiDAR, followed by intermittent airborne and terrestrial surveys.
Since 2018, high-frequency truck-mounted mobile LiDAR has been used which produces very high resolution, short interval change detection of bluff failures and retreat. This is the work most people are referring to when they hear “Scripps LiDAR measurements” today, and it is typically discussed in the context of bluff instability along South Beach and the LOSSAN rail corridor along the South Bluff. While Geocon understands that SIO has recorded episodic slope failures along North Bluff, to our knowledge, no peer-reviewed, long-term bluff-top retreat rates that are based on site-specific data have been published or adopted by regulatory agencies for setback determination at North Bluff, and therefore should not be relied upon, on its own, in lieu of a site-specific geotechnical investigation.
With respect to the North Bluff, it is Geocon’s opinion that the observational and event-based nature of the SIO data has not been developed, validated, or adopted as a regulatory or engineering basis for long-term bluff-top setback determination, and does not provide the engineering framework or sitespecific geotechnical investigation required for development-level setback decisions by the City of Del Mar. Additionally, the shorter duration of LiDAR monitoring does not capture the long-term episodic nature of bluff retreat along North Bluff evaluated in Geocon’s 87-year analysis.
NORTH BLUFF vs. SOUTH BLUFF
It appears that SIO researchers have recently focused their effort on South Bluff since it poses the greatest risk for instability due to its composition and has threatened the LOSSAN rail corridor with bluff collapse for some time. Geocon believes it’s important to provide some supplemental information to point out the differences in bluff composition and failure mode between South Bluff (rail corridor) and North Bluff considering the publicity that South Bluff is experiencing due to the rail line slope instability and bluff stabilization projects.
The South Bluff has a documented history of slope instability that has periodically affected the LOSSAN rail corridor, most recently prompting emergency repairs by SANDAG. Instability is primarily driven by exposed weak mudstone of the Del Mar Formation at the base of the South Bluff, which is highly susceptible to wave erosion and accelerated bluff retreat. Overlying low-cohesion terrace deposits are prone to toppling once this mudstone is undermined. This pattern of erosion and slope failure is recurrent along South bluff and is expected to intensify with sea level rise and major storm events. Groundwater migration from up-gradient irrigation and meteoric sources further exacerbates instability, with seepage commonly observed along the bluff face despite the installation of horizontal drains. As summarized in the City’s June 2021 letter to the CCC, there are over 500 homes along the South Bluff.
May 19, 2026 Item 8
- 7 - February 18, 2026
In contrast, the lower portions of the North Bluff that are exposed to wave erosion are composed of dense, well cemented siltstone and sandstone of the Del Mar Formation, overlain by very dense Torrey Sandstone. These competent materials form an approximately 30-foot-high near-vertical erosionresistant bluff face that functions similarly to a natural “sea wall,” resulting in substantially lower erosion and retreat rates compared to South Bluff. While six small sea caves have been identified at the base of the North Bluff, they are limited in size and generally oriented subparallel to the bluff face.
Due to their orientation, these features do not affect the site-specific building setback applied to future North Bluff development.
Bluff retreat at South Bluff is more rapid than that which occurs at the North Bluff because the failure modes are distinctly different. Bluff retreat at South Bluff is primarily due to rotational and translational landsliding resulting from a combination of inherently soft, highly fractured mudstone and heavy groundwater seepage. Bluff retreat at North bluff is primarily by infrequent small to moderate-sized block falls controlled by widely spaced bluff- parallel fractures and slow grain-by-grain erosion in wellcemented sandstone and siltstone.
SUMMARY
In summary, while the City’s draft Safety Element and its supporting CHVRA and CoSMoS analyses provide an appropriate regional framework for identifying coastal hazards and informing long-term policy and adaptation planning, it is Geocon’s position that these tools are not intended to replace sitespecific geotechnical evaluation for development-level decision making by the City. For the vacant and developed North Bluff properties, the comprehensive geotechnical investigations by Geocon, including detailed subsurface exploration, long-term historical and future erosion analysis considering the influence of sea level rise, bluff mapping, and slope stability modeling provides the most reliable and technically sound basis for evaluating bluff retreat and establishing building setbacks.
Additionally, regional modeling tools and observational LiDAR datasets, including those developed by USGS and SIO, are valuable for screening and monitoring purposes, but they have not been developed or validated with the duration and engineering analysis required to characterize localized geologic conditions, long-term recession rates and failure mechanisms, and determine building setback criteria for future development along North Bluff.
In conclusion, it is Geocon’s opinion that it would be inappropriate for the City to rely solely upon CoSMoS data in the City’s draft Safety Element for the North Bluff properties. Further, it is also Geocon’s opinion that the CoSMoS Phase 1 data should not be incorporated into the City’s policy framework. The City has copies of all site-specific investigations of the North Bluff properties, including the site-specific building setback to be applied to future North Bluff development. Accordingly, the sitespecific geotechnical studies by Geocon should remain the primary basis for setback determination and development planning for all North Bluff properties.

I wanted to express my opposition to the Seaside Ridge project. I find it to be an inappropriate location and as well it would add to the major traffic congestion on Via De La Valle due to all the events held at the Del Mar Fair Grounds throughout the year, especially the Country Fair and the Horse Races.
During events at the Del Mar Fair Grounds traffic on Via De La Valle is already backed up way beyond the 5 Freeway exit at Via De La Valle and because of this it takes an extraordinary amount of time just to get to the intersection of Via De La Valle and Coast Highway.
This project would add many, many more cars on Via Del La Valle and cause major congestion at the intersection of Via De La Valle and Coast
Highway.
Due to the congestion it would make it difficult if not impossible for emergency vehicles to get to where they need to get to in a timely manner.

Dear City Council,
I see that you will be discussing Affordable Housing (Item 9), and would like to remind you again in regards to parcel 3 and 1 that what we need down here in Old Del Mar is families. We need more kids and young people. Please make these affordable housings for families. An upgraded Shores park is on the horizon with hopefully a playground, basketball court and run-around area - plus area for dogs.Let's bring in families that will appreciate all that. Instead of squeezing in 8 miniature studios on ONE lot, please make parcel number 1 available too for affordable housing and put 4 good size units on each.
Why has parcel 1 been taken out of the equation? Put it back in. It's the same size as parcel 3 and not to mention the amazing view they will get there. If you don't want to put parcel 1 in, please give me a good explanation why that parcel is sacred and untouchable for Affordable housing, because to me and everyone else, it makes no sense. The only other reason that could make sense was that we need somewhere for the Alonzo house to be situated to free up more land for the park. But in all honesty, the Alonzo house comes from 10th Street and if we were to choose whether it should go to parcel 1 or 3, it should be placed on the parcel that sits on 10th street - parcel 3, out of historical reasons. Then build 4 family affordable units on parcel 1.
All in all - we need families! We need diversity in age AND economical situations. We want to see kids around around and growing up enjoying del Mar and growing up by the ocean. And soon there will also be a safe crossing close by over/under the railroad on the bluff. Give some kids the chance to grow up here! Best,

Dear Mayor Martinez, Council members Spelich, Quirk, and Gaasterland, Item #9 includes an update and discussion about the affordable housing plans for the 10th Street lot. The City has been working on this for many years, but unfortunately many neighbors still have not been told about this.
State law requires that notices be mailed to all property owners within 300 feet whenever there is to be a City Council vote related to the development of this property. This has not been done; so I hope that in the future the City will mail out the required notices and start posting them on their website.
It would also be very helpful if there was an Affordable Housing portal that included notices of the meetings and all of the available public records, documents and studies related to this property.
Thank you,
Joy Shadle Ehrenfeld

Re: Red Dot — May 19, 2026 City Council Agenda, Item 9
Dear Mayor Martinez and Members of the City Council:
This correspondence comments on behalf of Carol Lazier (“Owner”) as trustee of the Stensrud Lazier Holding Trust 10-17-11, owner of two parcels of real property identified as 929 Border Avenue, APNs 298-241-06 and -07 (herein, the “Property”) and discussed in the Staff report for Item 9 on your May 19, 2026, agenda.
While we appreciate and support the City’s efforts to meet its Regional Housing Needs Assessment (RHNA) targets, the Staff recommendation not only risks potential new violations of State housing laws by proposing to rezone the Property to a lower density than what was assumed in the City’s Housing Element and subjecting future development to discretionary review, but also proposes to do so in a manner that may significantly increase the timeframe to accomplish rezoning and delivery of housing by requiring extensive environmental review, notwithstanding recent changes in State law that exempt rezoning to implement the schedule of actions contained in an approved housing element. We therefore urge the City Council to proceed in accordance with State housing law to implement Program 1E to rezone the Property to the Housing Element Implementation Overlay Zone (“HEI-OZ”), codified at Del Mar Municipal Code (DMMC) Chapter
30.92, certified by the Coastal Commission and created “in anticipation of applying it to various parcels during the City’s 6th Housing Element Cycle (2021-2028)” including the Property (“up to six parcels along Border Avenue/North Bluff and up to three vacant parcels at the south end of Stratford Court”)1 to allow housing by right at a density of up to 25 dwelling units per acre (du/ ac).2
1 See Coastal Commission staff report, May 11-13, 2022, Item W16b, at w16b-5-2022-report.pdf. 2 The Staff report and recommendation also ignore the City’s obligations under State housing laws to approve the proposed Seaside Ridge Project (PDA 220-1/ CDP 23-008), which qualifies as a Builder’s Remedy project as defined in the Housing Accountability Act, Government Code section 65589.5(h)(11).
As the State Department of Housing and Community Development has advised, the City must continue to process housing development applications submitted during the time the City’s housing element was out of compliance, pursuant to Government Code section 65585, subdivision (d)(5). As the California Department of Justice has advised, regardless of the City’s motivation, evading a lawful Builder’s Remedy application would be a violation of Government Code section 65589.5, subdivisions (f)(6)(E) and (k)(1)(A)(ii)(IV). Further, the City cannot avoid its obligation pursuant to Government Code section 65583(g)(1), under State law to approve the Project, which includes at least 49% affordable units, because May 19, 2026 Item 9
May 19, 2026
The City is obligated to proceed with rezoning the Property to allow a maximum density of 25 du/ac pursuant to its Housing Element, Program 1E. The City has failed to meet the deadline to rezone the Property pursuant to Government Code section 65583.2(c) and has failed to meet the requirements of Housing Element Program 3A to secure a binding agreement with the 22nd District Agricultural Association (“22nd DAA”) for the siting of housing on the State Fairgrounds property by April 2024. Although the Staff report asserts that these mandates do not apply because the Property is a “contingency” site, Housing Element Appendix B-1 “Candidate Sites Analysis” includes the Property (Table B-7, “Low and Very Low-Income Sites”), and past City correspondence also identifies the Project site as a “candidate” site. The State Housing and Local Land Development Opportunities Map also identifies the Project site as a “Housing Element Site to be Rezoned” (see, Exhibit A). As such, the Property is required to be rezoned pursuant to Program 1E and State law.
Further, the public record is clear that no binding commitment to site housing on the State Fairgrounds property has been made. Notwithstanding the State Department of Housing and Community Development’s (“HCD”) correspondence with the City regarding the City’s continuing efforts to accommodate housing at the State Fairgrounds property, the 22nd DAA is not expected to complete its Master Plan efforts until 2027 and cannot feasibly make a commitment to a ground lease by November 2026. We also understand that a ground lease would require special legislation to extend the maximum time for a ground lease on the Fairgrounds property in order to make a project feasible, and which would not be effective (if adopted at all) until January 2027 at the earliest. Regardless, the fact remains that the express language of the City’s Housing Element requires a “binding commitment” to site such housing by April 2024 in order to avoid rezoning pursuant to Program 1E, a timeline that lapsed over two years ago. Accordingly, notwithstanding its continuing efforts regarding housing on the Fairgrounds property, the City is legally obligated to implement Housing Element Program 1E by rezoning the Property to allow a maximum density of 25 du/ acre.
CEQA (Pub. Res. Code §§ 21000 et seq.), as amended by Senate Bill (SB) 131 (2025), expressly exempts rezoning that implements the schedule of actions contained in an approved housing element. (Pub. Res. Code § 21080.085(a) [“This division does not apply to a rezoning that implements the schedule of actions contained in an approved housing element pursuant to subdivision (c) of Section 65583 of the Government Code.”].) To fit the exemption, the rezoning must exclude “Natural and protected lands” as defined in Public Resources Code section 21067.5 [“Subdivision (a) applies to a rezoning that contains within its boundaries any natural and protected lands as defined pursuant to Section 21067.5 if those natural and protected lands are excluded from the rezoning.”]. As demonstrated by the technical studies submitted for the proposed Seaside Ridge Project (PDA 220-1/ CDP 23-008), the areas of the Property proposed for development are not in a conserved or protected area, a Very High Fire Hazard Severity Zone, a hazardous waste site, wetlands or prime farmland, or a regulatory floodway as determined by FEMA in its official maps and do not contain an “environmentally sensitive area” as defined in Public Resources Code section 30107.5 (“area in which plant or animal life or their habitats are either rare or especially valuable”). SB 131 became effective as urgency legislation in June 2025, with the express intent to remove a major regulatory hurdle and prevent CEQA litigation from delaying critical housing sites. A full environmental impact report or extensive consistency evaluation is not necessary in light of the new statutory exemption and technical studies the Project is located on a site required to be rezoned pursuant to the City’s Housing Element. Please reference our full comments relating to the Project submitted with respect to Item 8 on today’s agenda.
May 19, 2026 Item 9
May 19, 2026
demonstrating the Property qualifies for the exemption, and would result in unnecessary delays in delivering housing in the City. Therefore, the City should proceed with rezoning the Property to the HEI-OZ to implement Program 1E subject to a statutory exemption under CEQA section 21080.085(a).
The Staff recommendation to initiate rezoning of the Property at a density of 20 dwelling units per acre would unduly reduce affordable housing capacity identified in the City’s 6th Cycle Housing Element and put the City at risk of violating the State’s “No Net Loss Law”, Government Code section 65863, unless the City demonstrates that it has adequate capacity to accommodate its RHNA or rezones alternative sites to accommodate the loss. The recommended action to initiate rezoning of the Property to allow housing development subject to future discretionary approval and CEQA review also violates the mandates of State Housing Element Law (Gov. Code § 65583.2(h)(1)) which requires the City to accommodate 100 percent of the need for housing for lower income households on sites that “shall be zoned to permit owner-occupied and rental multifamily residential use by right for developments in which at least 20 percent of the units are affordable to lower income households during the planning period.” (Emphasis added.) As such, the recommended action subjects the City’s Housing Element to potential decertification. (New Commune DTLA LLC v. City of Redondo Beach (2025) 115 Cal. App. 5th 111, 130.) The City should rezone the Property to the HEI-OZ to accommodate housing by right in accordance with State housing laws.
On behalf of the Owner, we therefore request the City Council proceed to rezone the Property to the HEI-OZ, subject to the statutory exemption from CEQA under Public Resources Code § 21080.085(a), to implement its Housing Element Program 1E. We appreciate the City’s efforts to further housing in the Coastal region and look forward to future cooperation with respect to development of the Property.
Sincerely,
Brooke Miller
