HomeMy WebLinkAboutPH-3 - 26-170 - Appendix B - Redline - 3/17/2026Appendix B: Sites Analysis B-0 ATTACHMENT 3 Sites Analysis (text updates to add two sites and remove 17 sites; a comprehensive update to be conducted following a No Net Loss analysis later in 2026) Appendix B Appendix B: Sites Analysis B-1 A. Candidate Sites Analysis Overview The Housing Element is required to identify potential candidate housing sites by income category to meet the City’s RHNA Allocation. The sites identified within the Housing Element represent the City of Costa Mesa’s ability to plan for housing at the designated income levels within the 6th housing cycle planning period (2021-2029). As described in this appendix, the development capacity for each site depends largely on its location within the City, a specific plan or urban plan area as well as known development factors. Where possible, property owners were consulted to help the City better understand potential future housing growth on candidate housing sites within the City. This appendix contains Table B-5, which identifies each candidate housing site within Costa Mesa’s sites inventory. The sites are identified by assessor parcel number (APN) as well as a unique identifier used to track sites within the inventory. Additionally, the following information is provided for each parcel.  Address  Ownership  Zoning (including Specific Plan areas, Urban Plans, and Overlays, if applicable)  Size (Net developable acres removing known development constraints)  Density  Vacancy status  Previous Housing Element identification  Potential Development Capacity (Dwelling Units) by income category  Description of existing use A summary of this information is included within the Housing Resources section (Chapter 3) of Costa Mesa’s 2021-2029 Housing Element. Table B-1 shows the City’s 2021-2029 RHNA need by income category as well as a summary of the sites identified to meet that need. The analysis within this appendix shows that the City of Costa Mesa has the capacity to meet their 2021-2029 RHNA allocation through a variety of methods, including:  Identification of development capacity on sites which either currently permit or will be rezoned to permit development of residential uses at or above 30 dwelling units per acre  Identification of City owned properties suitable for the development of housing  Future development of accessory dwelling units (ADUs) Appendix B: Sites Analysis B-2 Table B-1: Summary of RHNA Status and Sites Inventory (to be comprehensively updated following a No Net Loss analysis later in 2026) Very Low Income* Low Income Moderate Income* Above Moderate Income Total RHNA (2021-2029) 2,919 1,794 2,088 4,959 11,760 Units Constructed in Projection Period (Begins June 30, 2021) 3 19 9 8 39 Remaining Unmet RHNA 2,916 1,775 2,079 4,951 11,721 Large Sites Fairview Developmental Center 575 345 690 690 2,300 Sakioka Lot 2 120 60 120 900 1,200 Home Ranch 221 110 221 1,663 2,215 Senior Center Housing Project 40 20 0 0 60 Pacific Arts Plaza and Town Center 53 27 53 402 535 Total Potential Capacity - Large Sites 1,009 562 1,084 3,655 6,310 Overlays, Specific Plans, and Urban Plans North Costa Mesa Specific Plan 1,201 695 1,269 3,265 6,435 SoBECA Urban Plan 128 70 141 383 732 Mesa West Bluff Urban Plan 195 109 208 555 1,071 19 West Urban Plan 115 64 123 335 640 Harbor Mixed Use Overlay 270 151 286 778 1,485 Total Potential Capacity - Overlays, Specific Plans, and Urban Plans 1,909 1,089 2,027 5,316 10,363 Projected ADU Construction Projected ADU Construction 97 168 117 8 391 Sites Inventory Total Total Units towards RHNA 3,015 1,819 3,228 8,979 17,042 Total Capacity Over RHNA Categories 103% 102% 155% 181% 145% *The City’s Extremely Low Income (ELI) housing need is assumed to be 50% of the very low RHNA need for the planning period. 1. Approved Projects and Projects in the Pipeline Approved Projects since June 30, 2022 As shown in Table B-1, the City of Costa Mesa has approved residential development projects since the start of the projection period for the 6th Cycle. The projection period is the time in which development activity can count towards meeting the City’s 6th Cycle RHNA need. Cities within the Southern California Association of Governments (SCAG) region can begin taking credit for the 6th cycle for development that was approved on or after June 30th, 2021. Table B-2 contains projects that received approvals during that timeframe.

Pursuant to the HCD Housing Element Site Inventory Guidebook Government Code Section 65583.2, for projects yet to receive their certificate of occupancy or final building permit, the element must demonstrate that the project is expected to be built within the planning period. The City believes that many of these “in the pipeline” housing units are likely to be developed within the planning period and could further the City’s efforts in reaching its required RHNA, if/once developed. Although “projects in the pipeline” are not included as “candidate housing sites”, they represent opportunities for future housing construction in Costa Mesa within the planning period. If/when these housing units are built, the units will count toward achieving the City’s RHNA allocation as mandated by State law. The below summary includes housing projects at various planning/development stages, and consist of potential housing developments of various sizes, types and housing affordability ranges. The summary includes recent housing projects that have been submitted for land use approvals at this time but are not yet “approved”; projects that are “approved” but no building permits have been issued or applied for; and other housing projects that City staff is working on in partnership with other entities or agencies to develop housing resources in the City.  Senior Housing Project at the Senior Center (Jamboree Housing ENA) – On July 21, 2020, the City Council approved an Exclusive Negotiating Agreement (ENA) with Jamboree Housing Corporation in determining the feasibility, and potential terms, for the right to acquire a long-term leasehold interest in an approximately 0.90-acre portion of the parking lot at the Senior Center property to develop a senior housing project. The conceptual density study plans envisioned the potential for Appendix B: Sites Analysis B-5 60 senior affordable dwelling units at the site. An application for an Urban Master Plan Screening for the proposed project was submitted in November 2021 and staff continues to work with the applicant to bring the project forward for a decision.  Urban Plan Screening Project (1711 & 1719 Pomona Avenue) – On November 16, 2021, the City Council considered an Urban Plan Screening of a Master Plan request for eight live/work units on a 0.46-acre lot. The proposed Master Plan includes a deviation request from the Urban Plan’s live/work standards for minimum lot size. The urban planning screening process is the City’s first stage of development review for projects proposed in mixed-use overlay districts. The Council generally supported the project’s concept, including the request for a deviation from minimum lot size and provided the applicant guidance for the project proposal to include in a future application for Planning Commission consideration.  Urban Plan Screening Project (1540 Superior Avenue) – On January 18, 2022, the City Council is scheduled to consider an Urban Plan Screening request for nine live/work units on a 0.44-acre lot. The Urban Plan screening process is the City’s first stage of development review for projects proposed in mixed-use overlay districts. After the City Council screening, the applicant will use the City Council’s guidance to include in a future application for Planning Commission consideration.  One Metro West (1683 Sunflower Avenue) – The proposed project is a mixed-use development and consists of residential, specialty retail, creative office, and recreational uses. The project is proposed to include up to 1,057 dwelling units (anticipated to be rental units), 25,000 square feet of commercial creative office, 6,000 square feet of specialty retail, and 1.5-acres of public open space. The proposed development includes three multi-family residential structures with a maximum building height of seven stories; one stand-alone office building up to four stories in height; tenant-serving commercial retail space integrated into one of the residential structures; open space; landscaping; streetscape improvements; and a Class-I bike trail system on Sunflower Avenue providing access to the Santa Ana River Trail. The project was approved by City Council in 2021. The project includes 10 percent (106 units) of the residential development project component to be affordable (67 very low income units and 39 low income units) for 40 years. The proposed Project is subject to Measure Y, as codified in Article 22, Chapter IX of Title 13 (Zoning) of the Costa Mesa Municipal Code. Pursuant to Measure Y, after final approval by the City Council, including all CEQA review, the voters must then approve the Project.  Costa Mesa Village (2540 Newport Boulevard) – Costa Mesa Village is an existing 97-unit SRO/efficiency development which was redeveloped many years ago from an existing motel. An application to update and amend the original entitlement (which allowed for the conversion of the former motel into an SRO/efficiency unit development) was submitted in November of 2021. The intent of the Conditional Use Permit amendment is to modify and update the conditions of the original entitlement while adhering to the City of Costa Mesa’s recent SRO policy. The update will include revisions to enhance project housing and social services to qualified low-income individuals and persons with disabilities. Up to 23 of the 97 housing units are anticipated to be supported by Section a 811 subsidy administered by the California Housing Finance Agency (CalHFA) for persons with developmental disabilities, with the remaining units to continue as affordable housing units for individuals living/working in the City of Costa Mesa. The project is expected to be heard by the Planning Commission on January 24, 2022, with the final decision by the City Council thereafter.  Project Homekey – On November 16, 2021, the City Council directed staff to collaborate with the County of Orange and associated development partners to submit application(s) for the Homekey Program grant funding for the acquisition, rehabilitation and conversion of one or two motel locations proposed for permanent supportive housing. City staff have been working with several existing motel owners of properties that range between approximately 40 to 90 units. The Appendix B: Sites Analysis B-6 proposals will provide direct permanent supportive housing with funding from the City of Costa Mesa, the County and (if awarded) Homekey grant funds from the State. The target population for these units would include at risk or currently homeless individuals and seniors, age 62 and over, and chronic homeless individuals and couples, with a subset of the units for eligible persons that qualify for Mental Health Services Act (MHSA) programs. Because the City operates the 72 bed Bridge Shelter on Airway Avenue, the Homekey Program could provide a seamless opportunity to stabilize this most vulnerable population where supportive services are provided on site, in the expedited Homekey permanent supportive housing model.  The Plant (765-767 Baker Street and 2972 Century Place) – This project consists of the proposed renovation of three existing commercial buildings (containing the former Car Mart and Plant Stand) totaling 19,100 square feet, for retail and restaurant uses surrounding a central courtyard area. In addition, new buildings are proposed consisting of two greenhouse structures which will contain food stall uses, and a four-story mixed-use building with 48 residential units, 14 live/work units, and 2,570 square feet of workshop/maker office space above a two-level parking structure. This project was approved by the City Council in 2019.  Families Forward (Pomona Avenue) – Families Forward, founded in 1984, is committed to preventing and ending family homelessness in Orange County. Families Forward has acquired and is working on plans to rehabilitate and expand a multi-family property on Pomona Avenue. At completion, the project will include the interior and exterior renovation of the existing 6 units and the addition of 2 new accessory dwelling units that will collectively house 8 families at risk of, or experiencing, homelessness. Families Forward has submitted preliminary plans to the City and are working to advance construction plans which are expected to be submitted to the City for expedited review in January 2022. The project will be owned and operated by Families Forward but is being constructed as a collaboration between Families Forward and HomeAid of Orange County. Families Forward will provide wrap-around services to low- to moderate-income family residents and provide a case manager, housing resource specialist, and other professionals to build a plan toward self-sufficiency. The families will also receive supportive services such as counseling, career coaching and access to our food pantry. In 2020, Families Forward helped house and bring an end to homelessness for 15 Costa Mesa families (49 adults and children), with 33 Costa Mesa families accessing the Families Forward food pantry and taking another step towards stability. When complete, the Pomona project will serve as an entry point for families in and near Costa Mesa. Also, on November 17, 2020, the City Council approved a Subrecipient Agreement with Families Forward to establish a Tenant Based Rental Assistance (TBRA) program to assist qualified, very low-income households who are current residents of Costa Mesa (or households with strong community ties to Costa Mesa). For a variety of reasons, not all projects in the pipeline complete the planning approval or building permit process and are built and occupied. However, these projects provide an indication of what future housing construction may include within the Housing Element planning period. As indicated above, City staff will continue to work with the aforementioned project applicants and other City housing efforts to reach the City’s goals.

Selection of Sites The City of Costa Mesa has identified sites with capacity to accommodate the 2021-2029 RHNA. The City has identified 99 parcels within a variety of different zones, specific plan areas, urban plans, and overlays. Each of these either currently permit residential development or will be amended per Programs 3B and 3C to permit residential development at the densities specified in Table B-5. The identified sites have been evaluated to determine the extent to which on-site uses are likely to redevelop within the planning period. It was found that a number of the existing uses (identified in Table B-5) are either permanently closed or available for lease. Many of the uses are in multi-tenant commercial centers with one ownership and most show little to no evidence of recent investment or redevelopment. The City does not have access to most leasing information as these are generally private documents but has conducted an analysis to identify sites that show characteristics indicating they are likely to redevelop within the planning period. When possible, the City had discussions with property owners to determine interest in redevelopment for residential uses. The analysis also includes several letters of potential residential development interest in Appendix A. Community Input on Sites Selection Community input was an important component of the sites identification and selection process. The City conducted multiple public outreach meetings, including district specific meetings where community members gave input on areas of importance within their district. This information was collected as notes on maps of each district and can be found in Appendix C. Community members also provided feedback on potential housing development types and focus areas on the online community survey. Additionally, draft versions of the sites inventory were discussed at both Planning Commission and City Council study sessions, with decision makers providing input and community members able to make public comments. Lastly, the City held discussions with major property owners within the City to better understand their long- range plans for development of the properties under their ownership. The City used these discussions to more accurately determine potential unit yield and affordability assumptions for some of the identified candidate housing sites. Additional information is provided for specific properties in Table B-5. 3. Redevelopment of Non-Vacant Sites for Residential Uses The City of Costa Mesa does not have sufficient vacant land available to accommodate fifty percent of their low/very-low income RHNA. To accommodate the need at all income levels, the City has analyzed sites within non-residentially zoned areas that permit residential development through Specific Plans, Urban Plans, or Overlays. The City also evaluated and included parcels not currently within Urban Plans which will be added when those Urban Plans are amended as part of Programs 3B and 3C. As the City cannot accommodate 50 percent of the low/very low income RHNA, state law requires that the City analyze the following:  Analysis of leases that would prevent redevelopment of the site,  The extent to which existing uses may constitute an impediment to the future residential development within the planning period,  The City’s past experience with converting existing uses to higher density residential uses, Appendix B: Sites Analysis B-12  Current market demand for the existing use,  Development trends and market conditions, and  Regulatory or other incentives to encourage redevelopment. Lease Analysis Existing lease agreements on infill and non-vacant properties present a potential impediment that may prevent residential development within the planning period. State law requires the City to consider lease terms in evaluating the use of non-vacant sites, however the City does not have access to private lease agreements or other contractual agreements amongst parties because they are private documents. Therefore, the City has conducted an analysis to identify sites that show characteristics indicating they are likely to redevelop within the planning period, including past performance, an on-the ground existing use analysis and a market analysis to understand cost of land, construction, and development trends in Costa Mesa. Experience Developing Non-Vacant Sites for Residential Uses As part of the candidate housing sites analysis, the City has evaluated recent projects that have redeveloped within non-residentially zoned areas that included residential units. Those projects, including the zoning, use prior to redevelopment, and a project analysis of the approved development plan, are shown in Table B-3. The City’s analysis showed that prior uses on these redeveloped sites were similar in nature to the existing uses on sites identified within the sites inventory in Table B-6. Based on the information provided in Table B-3, the City has created a classification system for sites with characteristics that are applicable to the candidate sites inventory. The intent of this classification system is to draw parallels from past development and local knowledge and trends in development to the potential future development of the candidate housing sites identified. These classifications are based in real past development that has occurred within the City and while some comparisons may not be an exact match for the sites identified, they show a strong correlation with the understanding that every parcel is unique in terms of site characteristics, existing use, ownership, and other factors which can affect future development. The development classes are generally defined as:  Development Class A: Uses on these sites prior to redevelopment included either light industrial or office type uses. These are areas that previously served commercial or office businesses and have redeveloped throughout the city based on property owner interest and market trends. This also includes uses within the SoBECA Urban Plan area.  Development Class B: Uses on these sites prior to redevelopment included self-storage, vehicle storage, and industrial uses. Many of these sites are located within the Mesa West or 19 West Urban Plan areas which covers a large portion of the industrial areas within the City.  Development Class C: Uses on these sites prior to redevelopment included primarily commercial uses along Harbor Boulevard or another major city commercial corridor. These projects are typically in a mixed-use setting, whether within the same development or directly adjacent. Many of these sites are within the Harbor Mixed-Use Urban Plan area.  Development Class D: These sites are motel conversions within the City. The City is continuing to pursue Project Homekey funds to encourage redevelopment of specific motels within the City in coordination with property owners and operators of these buildings.  EX: Existing proposed project or anticipated project. Appendix B: Sites Analysis B-13 The City has also conducted a parcel specific analysis of existing uses for each of the identified sites. This analysis of existing uses, including indicators of a likelihood that the existing use will redevelop within the next eight years, are provided in Table B-6. This analysis is based on information readily available to the City and research that can be found through online research. The City does not always have access to private lease information but has included information that property owners have shared regarding individual sites. The following residential development projects have been constructed on parcels that were either non- residentially zoned or had an existing non-residential use on-site within Costa Mesa. Table B-3: Example Development of Non-Vacant Sites for Residential Uses Project Address Dwelling Units Zoning Use Prior to Redevelopment Project Analysis Development Class 125 Baker St. 240 PDR - HD Industrial use This development is a 240-unit wrap apartment complex on a 4.2-acre parcel in a largely industrial and office area of Costa Mesa. The project was built at a density of approximately 57 du/ac. The site was previously a light industrial and office uses use similar to some of the identified candidate housing sites. The project was rezoned from CL to PDR-HD. A 1957 Newport Blvd. 38 PDR - HD Self-storage use and trailer storage lot This development is a 38-unit condominium project along the Newport Blvd commercial corridor. The site was previously a self- storage and trailer storage use similar to some of the identified candidate housing sites. The project was rezoned from C1 to PDR-HD. B 2277 Harbor Blvd. 200 PDR - HD Motel use This development is a 200-unit apartment complex on a previous motel use site. This development is located on Harbor Boulevard and shares many existing characteristics with sites identified within this corridor in the candidate sites inventory. The project was rezoned from C1 to PDR-HD. D 671 W. 17th St. 177 MG Brownfield development (Argotech Industries) This development is 177 live/work and loft residential units and was developed on a site that was previously largely surface parking area.

This development is in the Mesa West Bluffs Urban Plan area along Placentia Avenue and previous uses are consistent with sites identified within the sites inventory. B This analysis of recent sample development projects shows that residential development occurs within the City on sites that have existing non-residential uses. As indicated in the analysis notes, these example sites share many characteristics with the candidate housing sites in Table B-6. This demonstrates that there is development potential on these sites as well as interest in developing these types of sites for residential uses within Costa Mesa. Existing Uses on Candidate Sites and Redevelopment Opportunity The City has identified and analyzed existing use on candidate sites in Table B-6 below. As the City is a built- out community, consisting mainly of commercial retail, industrial and single-family housing, a primary goal was to identify sites compatible for the development of multifamily and mixed-use housing as well as not displace existing residents. Therefore, the City identified the best possible sites with the most feasible opportunity for redevelopment over the next 8 years. In additional to the analysis in Table B-6 the City utilized locally available SCAG data to identify the following key indicators that the sites included for low and very low-income opportunity are the most appropriate: Nine percent of the sites are within areas identifies as Highest Resource by the TCAC 55 percent of the sites are within areas identified as moderate resource On average, there are 90 healthcare facilities within a one-mile drive from the identified sites On average, there are 4 grocery stores or markets within a one-mile drive from the identified sites 97 percent of the sites identified are within a High-Quality Transit area, meaning the 97 percent of sites are within one half-mile of a well-serviced transit stop or a transit corridor with 15-minute or less service frequency during peak commute hours. Housing Market Analysis In addition to an on-the-ground existing use analysis, the City of Costa Mesa has market conditions to facilitate the redevelopment of non-vacant sites for residential. Table B-3 above shows that a total of 1,167 dwelling units have been constructed through redevelopment in the City. Additionally, a California Association of Realtors report for Historic Housing trends shows that the average time a unit spends on the market in Orange County is just 18.6 days in the last four years (2017-2021) and just 13.3 days in the last Appendix B: Sites Analysis B-16 two years.1 Specifically in Costa mesa, homes spent just over one month on market and the sale-to-list price ratio was 100.14%, indicating a sellers’ market and the need for more housing.2 According to the New Homes Directory (online resource), historical Housing Market data, the average price for an attached unit, 1,500 square feet or less, increased by 48 percent over the last planning cycle ($434,87 in 2014 to $645,000 in 2021).3 Additionally, the according to the CAR Current Sales and Price Statistical Survey, the median cost of a home for sale in Orange County increased by 20 percent from 2020-2021 (from $930,000 in October 2020 to $1,120,000 in October 2021).4 The indicators above signify an increased market demand for new housing. 4. Development of Small Site Parcels The City of Costa Mesa has identified several candidate housing sites that are smaller than half an acre in size. Assembly Bill 1397 identifies general size requirements for candidate housing sites of greater than half an acre and less than 10 acres in size. The City has only identified sites smaller than half an acre which show the likelihood of redeveloping in conjunction with other parcels which collectively meet the half acre requirement or where the property owner/developer has provided a draft development proposal to the City. The likelihood of redevelopment was based primarily on common ownership amongst adjacent parcels which share a property line. In most instances, these parcels are currently developed as a single use and it is reasonable to anticipate that the collection of parcels will redevelop as one new development to maximize efficiency and design of the new use. Candidate sites less than half an acre in size represent a small portion of the City’s overall RHNA need. A total of nine sites comprise the potential for 114 units, which is 1 percent of the City’s total RHNA need for the period of 11,760. The potential candidate sites which are anticipated to be consolidated into a single development are identified within Table B-6. The candidate sites that are smaller than half an acre are shown in Table B-4 below along with descriptions of their likelihood to redevelop that go beyond the descriptions in Table B-6. 1 Median time on Market of Existing Detached Homes, Historical Data, California Association of Realtors (CAR), Accessed online: December 9, 2021. https://www.car.org/marketdata/data 2 Realtor.com, Housing Market Summary, Costa Mesa.

The property owner/developer provided a pre-application and rezoning application for a 10-unit residential development project. In February 2026, the property owner/developer requested to have the site added to the Housing Element. 42543103 20 1666 Superior Ave 19 West 0.29 These are all adjacent parcels in a contiguous block bounded by E 16th Street, Superior Avenue, E 17th Street, and Newport Blvd. All parcels within this block have been identified as candidate housing sites and total 4.70 acres. Sites 22 and 23 are owned by the same property owner. The existing uses are all car-related industrial uses which are single-story. As shown in Table B-2, the City worked with property owners of parcels along Industrial Way (Specifically 132, 134, and 140 Industrial Way, less than a quarter mile southwest of these identified parcels) to facilitate the development of residential uses on parcels previously occupied with the same types of uses as these three parcels (boat and auto repair uses). These parcels are located within the 19 West Urban Plan area and are permitted to develop in the same manner as the parcels along Industrial Way. 42543105 22 126 E 16th St 19 West 0.42 42543106 23 126 E 16th St 19 West 0.35 41817101 208 754 Saint Clair St SoBECA 0.27 These parcels are occupied by warehouse and light industrial uses within the SoBECA Urban Plan area. The SoBECA Urban Plan focuses on residential as a mixed-use component and promoting the development of residential in addition to the existing commercial anchors in the Mall and the Camp. The City has established Program 3D to update the Urban Plans within the City to focus more heavily on residential uses at the identified densities. As identified in Table B-2, the City developed Baker Block on industrial parcels which previously occupied similar light industrial uses in a largely industrial corridor approximately one-third of a mile from the 41817102 179 752 Saint Clair St SoBECA 0.26 41820202 182 841 Baker St SoBECA 0.33 41820205 185 2969 Century Pl SoBECA 0.09 13931321 203 1590 Adams Ave SoBECA 0.27 Appendix B: Sites Analysis B-18 Table B-4: Analysis of Candidate Housing Sites Under 0.5 acres APN Unique ID Address Specific Plan/Urban Plan Area Size (Ac) Use Description SoBECA area.

Home Ranch is currently a mostly vacant site within the North Costa Mesa Specific Plan area that has an existing development agreement and is currently planned for residential development. The City has actively worked with the property owner throughout the 6th Cycle Housing Element update process to identify an appropriate number of residential units to allocate towards the site. The property owner has indicated they intend to develop residential uses on the Home Ranch site and they are permitted to alter their development agreement or develop outside of it, meaning there are no unit caps in place. While this individual parcel is less than half an acre, it is in common ownership with the larger Home Ranch site which exceeds the half acre standard. This parcel is currently vacant. Additionally, Policy LU-2.10 of the City of Costa Mesa’s Land Use Element within the General Plan promotes lot consolidation of residential properties. While the sites identified in the table above are commercial in nature, the intent of the policy remains effective in consolidating smaller parcels towards the creation of a larger residential development. 5. Development of Large Site Parcels The 2021-2029 sites inventory includes several sites that are larger than 10 acres. These sites exceed the AB1397 size requirement and require additional analysis. The following background and analysis relates to each site in the inventory that exceeds that inventory. The City has conducted meetings with each of these major property owners to determine their future interest in developing housing on the identified properties. These properties when developed pursuant to the densities included within this Housing Element would be subject to the City’s inclusionary housing requirements which are in process and anticipated to be adopted per Program 2A. This supports the City’s assumptions of affordability on the sites described below. The housing element also includes Program 3R which commits the City to take actions to promote the development of large parcels at the densities and affordability levels identified Appendix B: Sites Analysis B-19 within the housing element. There are no unit caps within the City which would limit the number of units which can be developed on these sites. That is subject to the densities provided within the City’s zoning code. Fairview Developmental Center The Fairview Developmental Center (FDC) is a State-owned property that is approximately 109 acres in size and located on Harbor Boulevard within Costa Mesa. The FDC currently serves as one of the largest residential facilities for developmentally disabled persons in the State of California. The FDC was previously identified in the City’s 5th cycle Housing Element (2013-2021) and the City has continued discussions with the State to determine the potential residential yield of the area taking into consideration the existing uses. In January 2020, the Costa Mesa Fairview Developmental Center Ad Hoc Committee met to discuss potential development yields for the site. The Committee presented a report to the City Council which summarized its strategic engagement in the development of the local vision, priorities, and reasoning behind the stated preliminary vision of a solutions-based, housing-first model for the site. The Committee took into consideration the City’s recent efforts to open a homeless shelter and identified opportunities for permanent supportive housing and integrated workforce housing within the City. Conceptual yield studies and draft plans have also been compiled for the property and helped to inform development capacity assumptions. There are no current development agreements or density caps on the property as residential uses are not currently permitted. The City will need to come to an agreement with the State of California for future use of the site and then solicit input from the development community on potential entitlement, likely through a competitive bid process. The City is confident that there is significant interest in redeveloping the property once it becomes available based on informal discussions with developers during the housing element update process. FDC was discussed multiple times in public workshops by local housing advocacy groups in support of residential uses on the site for primarily affordable housing developments and workforce housing. The City has established Program 3B to work with the State of California to establish the FDC area as a mixed-use village that prioritizes housing and promotes development at the densities and affordability levels identified within this housing element. As stated in Program 3B, the City envisions a two-year process to negotiate future residential development use on the site. If not established within two years, the City will identify additional sites to accommodate a potential shortfall in sites to accommodate the remaining RHNA. The City’s 6th Cycle analysis includes an assumption of 2,300 dwelling units broken down into the very low, low, moderate, and above moderate-income categories. Sakioka Lot 2 Sakioka Lot 2 is a 30.93-acre site located north of the 405 Freeway with General Plan Land Use designation that allows up to 660 residential units, 863,000 Square feet of office or retail use and a Floor Area Ratio of 1.0. The property is also located in the North Costa Mesa Specific Plan. The site is currently under a development agreement (DA) that was recently extended for ten years until May of 2031. The City has had continued discussions with the property owners who have indicated there is the potential for future housing development on the site in strategic areas. This development would occur pursuant to the new densities identified within the Housing Element, which may lead to the development of more units than currently established under the DA. The property owner and City could Appendix B: Sites Analysis B-20 potentially amend the current DA or the property owner may develop outside of the DA but under the zoning requirements of the North Costa Mesa Specific Plan in order to achieve more than 660 residential units in the future. Therefore, the existing DA does not present a cap or restriction on the future number of potential units on the Sakioka Lot 2 parcel. Furthermore, there are not affordability caps within the current DA which would limit the number of units which may be affordable. The City’s 6th Cycle analysis includes an assumption of 1,200 dwelling units broken down into the very low, low, moderate, and above moderate-income categories. The property owner has expressed interest in communications with the City in developing for residential uses within the 8-year planning cycle. Home Ranch Segerstrom Home Ranch is a 43-acre site located north of the 405 Freeway with a General Plan land use designation that allows up to 1.2 million square feet of office and up to 0.64 Floor Area Ratio. The property is also located in the North Costa Mesa Specific Plan. The site is currently under a development agreement that was executed in 2002 and extended in 2010 for additional 20 years until July of 2030. The City has had continued discussions with the property owners who have indicated there is the potential for future housing development on the site in strategic areas. The property owner has expressed that there are future scenarios which consider fully developing the site for residential uses with some support commercial, which exceeds the assumptions in the housing element. The City conservatively analyzed the potential for a range of uses on the Home Ranch site. This would require a modification of the existing DA, which is possible with property owner and City support. The City’s 6th Cycle analysis includes an assumption of 2,215 dwelling units broken down into the very low, low, moderate, and above moderate-income categories. The property owner has expressed interest in communications with the City in developing for residential uses within the 8-year planning cycle. South Coast Plaza South Coast Plaza is a large regional mall in the North Costa Mesa area. The mall has ample surface parking and as of adoption of this Housing Element, has a large, big box component which is currently vacant. The City has had continued discussions with the property owners who have indicated there is the potential for future housing development on the site in strategic areas. The sites analysis makes a conservative potential redevelopment assumption of approximately 15 acres of the 128-acre property. The City’s 6th Cycle analysis includes an assumption of 1,959 dwelling units broken down into the very low, low, moderate, and above moderate-income categories. Pacific Arts Plaza Pacific Arts Plaza project is an 18.3-acre site located in South Coast Plaza Town Center currently developed with a variety of office buildings and restaurants. The site is designated Cultural Arts Center (CAC) by the General Plan and has a zoning designation of Town Center (TC). The property is also located in the North Costa Mesa Specific Plan. Portions of the site are under a Development Agreement. The existing development approvals referenced in the original Development Agreement that allows for a maximum Floor Area Ratio (FAR) of 1.55 and maximum building square footage of 1,227,978. The Development Agreement was recently extended for two years and will expire in August of 2023. The City has had continued discussions with the property owners who have indicated there is the potential for future housing development on the site in strategic areas. Appendix B: Sites Analysis B-21 The City’s 6th Cycle analysis includes an assumption of 535 dwelling units broken down into the very low, low, moderate, and above moderate-income categories. 6. Accessory Dwelling Units Accessory dwelling units, or ADUs, are housing units which may be developed in addition to an existing single- or multi-family residential use. These housing units can be free-standing or attached to a primary structure and are intended to provide additional housing on an existing residential lot. Often ADUs provide housing for family members or are rented to members of the community. As a result of new legislation and an increased effort by the City to promote ADUs, the City has seen an increase in applications so far in 2022. The City approved/permitted the following number of ADUs since 2018:  2018 – 4 ADUS  2019 – 6 ADUS  2020 – 19 ADUs  2021 – 43 ADUs  2022 – 68 ADUs Of the 41 permits issued in 2021, 1 was available at the extremely-low income level, 3 were available at the very-low income level, 25 were available at the low-income level, and 12 were available at the moderate income level. As of the end of April 2022, the City of Costa Mesa has seen an increase in ADU activity. The City has approved and is in the process of issuing permits for 27 ADUs through approximately one-third of the year. Projected out over 2022, this demonstrates the continued trend of ADU growth and puts the City on pace for 81 approved ADUs in 2022. This exceeds the City’s 2022 projection of 50 units by 31 units and positions the City well to exceed its projected ADUs within the planning period. In compliance with State law, ADUs are allowed in all zones that allow single dwelling unit or multiple dwelling unit development. Junior Accessory Dwelling Units (JrADUs) are permitted only in single dwelling unit zones. The City of Costa Mesa has determined based on past performance that it is appropriate to anticipate the development of 391 accessory dwelling units from 2021 to 2029 (approximately 50 per year through the planning period). Approximately 265 of these units are anticipated to be affordable at the low and very- low-income categories. A total of 117 ADUs are anticipated to be affordable at the moderate-income level and 8 ADUs are anticipated at the above moderate-income level. This affordability estimation is based on guidance from SCAG and HCD based on surveys of existing ADUs in the SCAG region between April and June 2020. Another local factor that contributes to the City’s anticipated overall ADU growth expectations is that the City’s ADU provisions are more flexible than the State ADU regulations, and therefore are more desirable for ADU development. For example, the State’s minimum standard related to ADU required parking is that ADU’s located within 500 feet of certain transit areas are not required to provide parking, whereas the City’s ADU standards allow ADUs to be constructed without any parking regardless of location. Also, the State’s minimum standard related to ADU height is that a local ADU ordinance shall allow an ADU Appendix B: Sites Analysis B-22 height a minimum of 16 feet, whereas the City’s ADU height standards allow a building height of 27 feet. Lastly, the State’s minimum floor area requirement for ADUs is 850 square feet for studio units and 1,000 square feet for one-bedroom units, whereas the City’s ADU floor area standards allow for larger ADUs in that a detached ADU can be constructed up to 1,200 square feet, and an attached ADU may be the greater of 1,000 square feet or 50 percent of the size of the existing residential unit. The City performed a trend analysis looking at the growth in ADUs from 2018 – 2021. That analysis is shown in the table below. Table B-5: ADU Assumption Analysis (2018 – 2021) Year ADU Permitted (2018-Based Strategy) Projection Period Total: 390 2028 50 2027 50 2026 50 2025 50 2024 50 2023 50 2022* 68 2021* 43 2020* 19 2019* 6 2018* 4 “*” indicates actual permitted ADUs within that year. As shown in Table B-4, Costa Mesa has seen sustained increases in ADU production each year since 2018 with the lowest being a 50% increase between 2018 and 2019 as new State laws and local processes were not common knowledge amongst homeowners. The City expects that they while ADU production is likely to continue to increase year after year, there may be some drop off in that increase as more property owners develop ADUs. The City anticipates approximately 50 ADUs will be permitted per year for the remainder of the planning period. A further indication of this is recent development trends observed by the City. Planning staff recently received and processed a development which included 13 ADUS which were conversions of existing garages. These units ranged from 152 to 363 square feet and consisted of a studio unit arrangement with one bathroom. This is a direct result of two actions: (1) developers and local property owners becoming educated on the new ADU laws and (2) the City of Costa Mesa making diligent efforts to discuss ADU potential and provide informational materials to the community. In addition to the methodology and concrete local data presented above, the City understands that ADU trends may change. In response, the housing element includes Program 3M to monitor ADU production every two years and has stated actions should production not match the anticipated amount in the housing element. To assist in furthering the recognition and understanding of ADUs potential within Costa Mesa and reach the City’s ADU development projections, Costa Mesa has included Program 3E, which identifies actions the City will take to promote and incentivize the development of ADUs during the planning period. As outlined in the program, these actions include: Appendix B: Sites Analysis B-23  Coordinating with the County on implementation of a permit-ready ADU program  Post a user-friendly FAQ on the City’s website to assist the public with the general questions.  Waiving specific permitting fees to make ADU development more feasible  Creating an expedited plan check review process to ease the process for homeowners  Research potential State and Regional funding sources for affordable ADUs and make the information found publicly available to homeowners 7. Water, Sewer, and Dry Utility Availability Each site has been evaluated to ensure there is adequate access to water and sewer connections as well as dry utilities. Each site is situated with a direct connection to a public street that has the appropriate water and sewer mains and other infrastructure to service the candidate site. The City has sufficient total water and sewer capacity (existing and planned) to accommodate the 2021-2029 regional housing need. The City plans for future housing growth through the Mesa Water District Urban Water Management Plan (UWMP). This was most recently updated in 2020. Future sewer capacity is planned for through the Costa Mesa Sanitary District Sewer System Management Plan (SSMP), which was most recently amended and recertified by the Board of Directors in January 2021. B. Calculation of Unit Capacity This section contains a description of the candidate sites identified to meet Costa Mesa’s RHNA need at all income levels. The full list of these sites is presented in Table B-6. 1. Realistic Capacity and Affordability Calculations Costa Mesa’s 2021-2029 Housing Element sites analysis assumes that each identified candidate housing site will develop with at a range of income levels. Primarily, it is assumed that sites identified within Table B-6 will redevelop with the following affordability characteristics:  30% of units available to residents in the low and very low-income categories  20% of units available to residents in the moderate-income category  50% of units available to residents in the above moderate-income category Costa Mesa recognizes that not all sites within the inventory will develop such that they meet these affordability assumptions and has included a 37% buffer on the total number of units to assist in accommodating potential differences in future housing development. This buffer is to accommodate the potential that sites may develop for 100% nonresidential uses, however recent development within Costa Mesa has indicated that is unlikely. The following developments have all occurred recently within the City’s urban plans, specific plans, overlays, or on non-residentially zoned sites. Many of these are described in more detail in Table B-2.  2277 Harbor Blvd – Previous motel use that underwent a rezone from C1 to PDR-HD and developed as a fully residential project with 200 apartment units.  671 W 17th Street – Previous industrial brownfield site in the Mesa West Bluff Urban Plan which developed as a fully residential project with 177 live/work units. Appendix B: Sites Analysis B-24  1620 and 1644 Whittier Avenue – Previous industrial use in the Mesa West Bluff Urban Plan which developed as a fully residential project with 89 live/work units.  1500 Mesa Verde East Drive – Commercially zoned parcel along Harbor Boulevard which developed as a fully residential project with 215 senior apartments.  Brickyard East and West – Previous industrial warehouse uses along Placentia Avenue which developed as a fully residential project with 29 townhouse units. Consistent with local housing market trends data presented earlier in this appendices, the City of Costa Mesa is seeing an increase in residential development and rarely receives requests for fully non-residential uses in the area identified within the candidate housing sites analysis. The City has established goals and programs within the Housing Element aimed at identifying funding opportunities and partnering with the development community to increase the amount of affordable housing built in future developments. If the City is able to identify partnerships leading to fully affordable projects, that would also help to cover any potential shortfall in capacity in any of the four income categories. The City of Costa Mesa recognizes that should a “No Net Loss” situation occur, they will be required to identify additional sites and has analyzed additional potential housing sites within the Housing Element’s environmental clearance document. There are several candidate housing sites in which the affordability assumptions differ from those presented above. Those sites include:  APN 418-181-11 (address to be assigned). This site was developed as a surface parking lot. The property owner/developer has applied for a pre-application and rezoning to accommodate a ten- unit residential development with one low income unit. The other nine units are assumed to be affordable to above moderate income households.  Costa Mesa Senior Housing Project (APN 424-211-01). This site is owned by the City of Costa Mesa who has had previous discussions with a developer on a fully affordable project on this site. This site assumes 60 units which are all affordable at the lower income levels.  Fairview Developmental Center. This site is analyzed previously in the large site analysis portion of this appendices. This site is owned by the State of California and the City anticipates working in collaboration with the State to support the goal of developing affordable housing. The City has assumed that approximately 40% of the units on this site will be available to residents at the lower income levels, while 30% will be available to residents at the moderate-income levels. The remaining units are anticipated to be market-rate.  Sakioka Lot 2. The City has conducted outreach meetings with this property owner and determined that it is realistic to assume that 15% of future units on this site may be available to residents at the lower income levels. This site has an existing development agreement.  Home Ranch. The City has conducted outreach meetings with this property owner and determined that it is realistic to assume that 15% of future units on this site may be available to residents at the lower income levels. This site has an existing development agreement.  Pacific Arts Plaza and Town Center. The City has conducted outreach meetings with this property owner and determined that it is realistic to assume that 15% of future units on this site may be available to residents at the low and very-low income levels. This site has an existing development agreement. Appendix B: Sites Analysis B-25 2. Specific Plan, Urban Plan, and Overlays As identified in Programs 3B and 3C, of the Housing Plan (Chapter 4), the City will be modifying some of the existing Specific Plans, Urban Plans, and Overlays within Costa Mesa. The densities identified in Table B-6 reflect revisions to many of these areas to permit residential development at a higher density than what the current zoning permits as of adoption of this document. As noted, the City has three years to complete these zoning amendments. The City is proposing to either analyze or modify the following areas:  North Costa Mesa Specific Plan  19 West Urban Plan  SoBECA Urban Plan  Mesa West Bluff Urban Plan  Residential Ownership Urban Plan (Propose to Remove)  Residential Incentive Overlay  Harbor Mixed-Use Overlay These areas, with the exception of the Residential Ownership Urban Plan, which is proposed to be removed, will be modified through Programs 3B through 3C to permit residential development at or above the default density for Costa Mesa of 30 dwelling units per acre. When considering appropriate densities, the City held outreach meetings with members of the community, decision-makers, the development community, and major property owners. As part of these meetings, the City discusses and analyzed what densities were appropriate to maintain the character of the surrounding neighborhoods while also presenting the opportunity for future residential development that can realistically facilitate the development of units available at the lower income levels. The City will continue to conduct community outreach post adoption of the Housing Element to discuss potential revisions to development standards within these areas with the goal of effectively planning for future affordable housing. Densities established as a part of future zoning changes must accommodate the densities shown in Table B-6 for the sites identified.

Class Plan Area has seen significant past ownership interest in conversion of existing commercial/light industrial/office into residential development with similar previous existing sites (including more than one-hundred multi-story residential loft units located immediately across 17th Street). Further, one of the main objectives of the 19 West Urban Plan is to “encourage commercial/residential mixed-use development” with an emphasis on “vertical mixed-use development” (i.e., multi-story). Based on past local development trends and future allowed increases in residential density, It is conceivable and likely that the economic return of a residential use will encourage the ownership to redevelop the existing storage use into either residential or residential mixed-use (similar to adjacent properties) within the planning period.
