Master Plans
Guidelines for master plans are included in section 17.36.050 of the Atherton Municipal Code and require that “where such master plans are prepared, they should be general enough to allow flexibility and adjustment of the facilities’ locations but shall have specific projections such as enrollment or floor space proposed. It is further requested that the schools involve interested neighbors, residents, town representatives, and others in the preparation of such master plans. Suggested content of master plans includes:

A. Land uses, their location, and extent;
B. Circulation patterns;
C. Locations for parking and parking standards;
D. Current enrollment projections and maximum enrollment anticipated; E. A list of possible facilities to be developed;
F. A schedule or priority of development;
G. Identification of historic or other unique facilities, heritage trees, and their disposition;
H. Identification of uses and their days and hours of operation, including evenings; and
I. Identification of other institutions or uses at the facility.

Where master plans have been prepared and adopted by schools, it is requested that they be filed with the office of the town planner for public record. The town planner shall report annually to the planning commission at a regular meeting on the status of school master plans, their availability, and contents. Each private school in Atherton shall report to the planning commission meeting to provide input on the status of master plan preparation and implementation. In addition, the annual meeting shall be noticed to all property owners within five hundred feet of the boundaries of the schools.” While the master plan process requirements are vague, they stand as a constraint to housing production as all multi-family housing developments on PFS zoned sites, the only sites where multi-family housing is allowed, are required to develop a master plan through the master planning process. The master planning process involves developing master plans that allow for flexibility and adjustment of locations, as well as a plan that involves “interested neighbors, residents, town representatives, and others”. All multi-family housing development projects on PFS sites are also required to be on areas highlighted by the master plan to include multi-family developments and must also be reviewed in a public hearing and location and environmental review. While the processes are themselves, and individually not to lead to a denial of multi-family projects, the inclusion of an initial master plan review period and a subsequent location and environmental review period for any planned multi-family developments extends the timeline of

approval for projects and stand as timeline constraints to housing production and development.

Affordable Housing Streamlining Process (SB 35)
The Town does not have an Affordable Housing Streamlining process and all applications for affordable housing units must comply with the development review process for all other applications and developments. Additionally, the Town does not have any sites eligible for streamlined approval under SB-35.

Program 3.818 directs the development of an Affordable Housing Streamlining process compliant with Government Code section 65913.4 in such case so the Town is prepared should it be subject to SB 35 streamlining in the future.

Local Ordinances
Chapter 17.50 of the Atherton Municipal Code requires landscape screening on most development projects. Landscape screening involves the development of a landscape screening plan to be reviewed by the Town Arborist, as well as a landscape screening agreement which outlines conditions for installation and maintenance of landscape screens on the property. The requirement of the installation, maintenance, and review of a landscape screen can be considered a constraint on the timeline and cost of housing development. Program 3.819 will clarify that landscaping requirements will be revised to as to be objective and not a constraint on affordable and/or multi-family residential development (including deed-restricted ADUs).

3.516 Constraints on Persons with Disabilities
Chapter 17.17 of the Atherton Municipal Code provides for reasonable accommodation to people with disabilities and complies with the Fair Housing Amendments Act of 1988 and the California Fair Employment and Housing Act.

The applicant requesting a reasonable accommodation must provide (17.17.030):

A. A completed town application indicating, among other things, the applicant’s name, address, and telephone number
B. The address of the property for which the request is being made C. The current actual use of the property
D. The zoning code provision, regulation, or policy from which reasonable accommodation is being requested
E. The basis for the claim that the person(s) for whom the reasonable accommodation is sought is/are considered disabled under the Fair Housing Act and why the accommodation is reasonably necessary to make specific housing available to the person(s)
F. Such other relevant information as may be requested by the town planner or his or her designee

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
133
F is a constraint and will be removed by Program 3.822(C).

17.17.040 outlines procedures guiding Town Planning staff for how to respond to requests for modifications or exceptions to Town land use, zoning, rules, policies, and procedures that act as barriers to equal opportunity to housing. When a request for reasonable accommodation is made and “related to a physical improvement that cannot be constructed to conform to the Town’s setback or design standards”, the Town Planner must, within 30 days after receiving the request, make a written determination regarding modifications or exceptions to Town regulations, or the request must be referred to the Planning Commission.

Requested accommodations that are not “’staff-level’ in nature” are to be deferred to the planning commission via a conditional use permit process. This is a constraint, and Program 3.822 (C) directs the rewriting of the Reasonable Accommodation process to make all decisions ministerial.

Section 17.17.040 gives the applicant the opportunity to appeal, in which case a new 30- day period of Town Planner review is provided.

The application submittal materials and process require a brief written narrative describing the development standard in which an exception is requested, why the reasonable accommodation is being requested and a brief statement from the applicant’s doctor stating the person’s disability.

Chapter 17.17 also provides a process for requests for reasonable accommodation relating to increased occupancy of a group home.

The Town does not define the term “family” and does not limit the number of unrelated individuals who may reside in a residence. Group homes for six or fewer residents are allowed by right in the single-family residential districts. The Town does not have any spacing or concentration requirements. The Town has only two residential zoning districts; both of which are for single family residences. Therefore, allowances for group homes with more than six residents specifically for the disabled in other zoning districts are not necessary. The Town does not have any parking standards therefore there is no need for relaxed parking standards for persons with disabilities.

Atherton uses the 2022 California Building Code. The adopted Code does not include any amendments that might reduce the ability to accommodate persons with disabilities. Accessibility retrofits are handled through the standard permit process.

However, permits are not required unless thresholds of health, life, and safety are exceeded. The California Building Code provides an option for meeting code requirements, whereby an applicant submits an alternative “methods and means” checklist to the Building Official noting the proposed design, the conventional design, and the rationale for the request.

Given that less than 10% of the population in Atherton has a disability, which per ABAG’s Data Viewer is comparable to most of the surrounding San Mateo County jurisdictions, the current approach serves this specialized population well and does not act as a constraint towards this population.

3.517 Constraints on Emergency Shelters
There is one parcel located within the Town Civic Center property, 2.46 acres in size. The latest Point-in-Time count, in 2022, identified 3 unsheltered persons in the town. This is an increase from recent counts, which alternated between 1 person and 0 people in the biannual counts from 2011-2019.

Program 3.824(A) directs Zoning Code Section 17.36.060, which describes standards for emergency shelter operation, to be updated as follows to meet current law:

A. Size. Emergency shelters shall not exceed one thousand square feet in floor area.

Analysis: Because 500 square feet per unsheltered person is required as per Government Code section 65583(a)(4), and Atherton had 3 unsheltered persons in its last Point-in-Time count, the 1,000 square foot size limit is now a constraint. It will be removed.

B. Beds and Population. The maximum number of client beds permitted in each emergency shelter shall be three and the maximum client population permitted to be served nightly by the facility shall be three.

Analysis: Three beds is a constraint on feasibility. This limit will be increased to 15 beds allowed by-right, with more allowed with a conditional use permit.

C. Location. Each emergency shelter shall not be located within a one-thousandfoot radius of another emergency shelter.

Analysis: No modifications are necessary.

D. Parking. At least one standard size car parking space per emergency shelter bed shall be provided within fifty feet of the emergency shelter.

Analysis: Requiring parking is a constraint. This will be modified to set parking standards at “at a number sufficient to accommodate staff and not exceeding the standards for other uses in the PFS zone.”
E. Waiting and Client Intake Areas. On-site waiting and client intake areas shall be located within the emergency shelter and shall not exceed two hundred fifty square feet in floor area.

Analysis: The size limit is a constraint and will be removed.

F. Handicap Accessibility. Each emergency shelter shall be completely handicap accessible.

Analysis: No modifications are necessary.

G. On-Site Management. Space for on-site management shall not exceed five hundred square feet and shall not include more than two beds.

Analysis: This section is a constraint and will be removed.

H. Exterior Lighting. All exterior lighting shall be shielded or downlit so the source of light is not visible from other properties.

Analysis: This section is a constraint and will be removed.

Siting
The 2.46-acre parcel where emergency shelters are allowed by-right are subject to a siting analysis, reviewing proximity to transit and services, hazardous conditions, habitability, and feasibility of emergency shelter construction per AB 2339 (2022). This parcel is zoned PFS, which will be modified to allow residential as part of housing element Program 3.813 Thus, the City’s parcels which allow emergency shelters as a permitted use meet the requirement under AB 2339 to also allow residential use.

Proximity to Transportation and Services
The parcel currently designated for emergency shelter use is very close (700 feet) to El Camino Real, the only road in Atherton with bus service. Although there are no services to support unsheltered persons in Atherton as of yet, the Samtrans busses on El Camino Real can connect individuals to commercial and health services in neighboring Redwood City and Menlo Park, as well as further afield.

Hazardous Conditions
The parcel was recently redeveloped, and in the course of redevelopment no hazardous conditions were identified.

Human Habitability
The parcel is home to Atherton’s city departments, post office, and library. In addition to El Camino Real 700 feet to the parcel’s south, Holbrook-Palmer Park – the largest park in Atherton – is less than a quarter-mile to the parcel’s east.

Feasibility
Atherton recently completed a site redevelopment plan for the Town Center, which began in 2014 and concluded in 2022. An emergency shelter was not part of this redevelopment, but there remains sufficient open space on the parcel for an emergency shelter of appropriate size to be developed, should the Town identify a partner organization that could support such a project.

3.520 Non-Governmental Constraints Analysis

3.521Land Prices
Land scarcity and high real estate prices are the most significant non-governmental constraints to affordable housing in Atherton. There are virtually no vacant lots in Atherton. Property values in Atherton greatly outpace average land cost in other jurisdictions in San Mateo County. Land currently sells for approximately $8 million dollars

per acre and can only be acquired by purchase of a developed parcel or by subdividing the property, which also most likely involves the removal of an existing residence. The Town believes that the high cost of land deters development opportunities for large-scale affordable housing projects. A distributed approach through the use of an ADU and JADU development and rental program (Programs 3.812 (A) and (B)) mitigates the high cost of land and will ultimately be more successful. The Town has also identified several properties for rezoning to permit multifamily housing. Figure HE – 38 below shows the radical difference in home values in Atherton that reflect the high cost of land as compared to other jurisdictions in San Mateo County and throughout the Bay Area.

FIGURE HE – 38: HOME VALUES IN ATHERTON, SAN MATEO, AND THE BAY AREA Source: Zillow
According to the California Department of Housing and Community Development AFFH Data Viewer (HCD data viewer), Atherton does not have public housing buildings.

Atherton also does not have a significant share of households using housing vouchers.

Compared to nearby Redwood City and Menlo Park, to the Town’s knowledge, the Town does not have housing stock available to renters with housing vouchers. The lack of presence of housing voucher users could indicate limited or no rental supply to house these residents.

Bay Area policies are interconnected; Atherton’s land use policies that limit the parcel size and restrict multifamily development contribute to housing shortages in other areas of the county. Due to the high cost of housing, town employees and service workers are forced to other areas in search of affordable housing that is not found in the town in

which they work. However, the Town is including multifamily housing as a rezoning strategy in the housing element and will introduce deed restricted ADUs to expand rental housing opportunities in Atherton.

FIGURE HE - Figure HE – 39 shows that Atherton has fewer renter-occupied households compared to San Mateo County and the Bay Area. 40% of San Mateo County households are renters compared to only 7% in Atherton. This suggests that workers who cannot afford to own homes in Atherton must rent elsewhere in the county, given the very limited numbers of rental units in Atherton. There are only 150 renter households in Atherton compared to 2,065 owner-occupied households in Atherton. These statistics do not include multi-family rental opportunities at school sites. Both numbers have stayed relatively stagnant since 2000. Renters in Atherton are young: 74% of those aged 15-24 and 88% of those aged 25-34 are renters. Unless they benefit from familial wealth, these renters must leave the town to purchase homes. Data is from ACS 5-year data (2015- 2019).

According to ACS data, there are no multi-family homes, boats, RVs, vans or other types of housing in Atherton. 93% (2,021) of detached single-family homes are owner-occupied and 7% (150) are renter-occupied—providing the only rental stock in Atherton. All

attached single-family homes (38) and mobile homes (6) are owner-occupied. Attached single-family homes have grown by only 30 homes and single family detached homes have lost 61 units in the past decade. The California Department of Finance counts six multi family homes with two to four units built in 2020.3.522 Construction Costs Construction costs include both hard costs, such as labor and materials, and soft costs, such as architectural and engineering services, development fees and insurance. For multi-family homes in San Mateo County, hard costs account for approximately 65 percent of the building cost and soft costs average around 21 percent (the remaining 14 percent is land costs). For single family homes, hard costs often are roughly 44-59% of the total cost, soft costs are 14-17%, and land is 24-42% of the total cost60.

While multi-family construction is less relevant in most of the town, it is relevant on school facilities. According to housing developers in San Mateo County, construction costs for multi-unit buildings vary based on the form of parking (structured vs. surface) in addition to other environmental factors such as topography, pre-existing structures etc. For smaller and larger multi-unit buildings, costs can range from $672,500-$846,500 per unit61.

For a 2,600 square foot single-family home the average cost of construction is approximately $420/sf. For a more expensive, 5,000 square foot home, however, the construction costs can average $525/sf. In general, soft costs add another approximate 20-25% to the subtotal62. Such costs are not particularly higher in Atherton than in other surrounding jurisdictions.

3.522 Availability of Financing
The availability of capital to finance new residential development is a significant factor that can impact both the cost and supply of housing. Two types of capital are involved in the housing market: 1) capital used by developers for initial site preparation and construction and 2) capital for financing the purchase of units by homeowners and investors. Interest rates substantially impact home construction, purchase, and improvement costs. Fluctuation in interest rates can have a significant impact on costs for construction or purchase, as well as impact whether a potential buyer can qualify for a loan.

Because interest rates are determined by national policies and economic conditions, there is little that local governments, including the Town, can do to affect the interest 60Century Urban LLC, Memo to Baird + Driskell, San Mateo and Santa Clara Counties Development Cost & San Mateo Unit Mix Research, April 7, 2022.

rates. In general, financing for both construction and long-term mortgages is available in San Mateo County, subject to normal underwriting standards.

Table HE - 34 summarizes the total number of home loans applied for, approved (and originated), and denied within the San Jose-San Francisco-Oakland MSA. In 2020, a total of 97,147 applications for home loans were submitted within the MSA. Of these loan applications, over 66% were approved and originated while approximately 11% of applications were denied. While there are many potential reasons for denial, this percentage of loan approvals and denials vary throughout the MSA by income group.

As anticipated, there is a direct relationship between household incomes and home loan application approvals and denials.

As depicted in Table HE - 34 as household incomes rise, the percentage of home loans denied decreases and the percentage of loans approved increases. Similarly, as household income falls, the percentage of home loan applications denied increases and the percentage of loan governs approved decreases. This data suggests it is much more difficult for lower-income households in the MSA to obtain home loan financing than higher-income households. This difficulty has the potential to directly affect the production and rehabilitation of housing units serving lower-income households, throughout the MSA.

Most homes in Atherton are custom-built homes funded by individual households.

Fluctuations in recent years due to the pandemic have caused caution among lenders and may have lasting effects on the availability of financing throughout this Housing Element planning period. Financing for this type of construction is more difficult to obtain now that banks have increased their requirements. While financing is no more of a constraint in Atherton than in other communities in the Bay Area, the availability of financing for developers under these economic conditions may pose a constraint on development outside of the Town’s control.

3.600 REVIEW OF 2015-2022 HOUSING ELEMENT

PERFORMANCE

3.610 Effectiveness of the Element
This update of the Atherton housing element provides an opportunity to reflect on past achievements and challenges, identifying what is working and what is getting in the way in meeting Atherton’s housing needs. This section reviews the previous cycle’s progress in meeting RHNA, reviews the previous (5th Cycle) Housing Element programs, and discusses the implementation of those previous cycle programs.

3.620 2015-2022 RHNA Progress in Implementation
A comparison of the number of projected or planned housing units (i.e., 2015-2022 Housing Need Allocation) with what was actually achieved is summarized in Table HE -35 below. The Town’s Regional Housing Needs Allocation (RHNA) for the prior (2015- 2022) period was 93 units. This included 35 very low income units, 26 low income units, 29 moderate income units, and 3 above moderate income units as seen in Table HE –

35. Actual housing construction during the 2015-2022 period was 247 units.

Note: Totals through Dec. 2021
There were a number of notable accomplishments related to implementation of the Atherton housing element over the past eight years:

ADUs (often referred to as second units or in-law units) have become increasingly popular after the Town adopted amendments to the ADU ordinance, most recently in 2020. Prominent Ordinance revisions which support this projection and increased production trend from prior years beyond those amendments as prescribed by

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
141
Government Code Sections 65852.2 and 65852.22 included additional floor area exemption up to 1,200 square feet beyond the first 800 square feet and increased public education on the construction of ADUs. It is noted that throughout 2022, a total of 27 new single-family permits were issued and these permits included a total of 26 new ADUs, and 5 ADU conversions. This nearly one to one ratio is a direct correlation to the Town’s encouragement to produce ADUs. The total number of ADUs permitted and/or constructed between 2015 and 2022 (the last year with data available) was more than 115. This exceeded the Town’s RHNA allocation. This is important, not only because ADU construction is the most viable form of new housing in Atherton, but also because rental surveys of ADUs show that these kinds of units are more affordable.

These ADUs were categorized under the RHNA Income Groups of Very Low, Low, and Moderate. The 115 ADUs exceeded the Town’s RHNA allocation of these RHNA categories by 25 units (the total RHNA allocation for Very Low, Low, and Moderate groups was 90 units). Additionally, results from a recent Town-wide survey indicate significant support for the development of ADUs over the next 8 years showing a more than 200 property owner commitment to do so.

The Town approved dormitory housing consisting of 147 units or a total of 291 beds at Menlo College. Of these, 19 of the units were dedicated for low-income students with incomes at or below 80% of the Area Median Income (AMI). The new dormitory housing alleviated demand for other units from students and housed a number of students who were previously unhoused. As student housing not open to the public at large, these units do not count towards meeting RHNA.

Construction of new Above Moderate market rate housing also exceeded the Town’s RHNA allocation. A total of 9 net new Above Moderate market housing units were constructed during the 2015-2022 cycle. On the required CA Department of Housing and Community Development (HCD) form the summary Table B only counts newly constructed units and does not account for demolished units. There were 132 new units constructed and 123 existing units demolished.

3.630Review of Prior Housing Element Programs
The following summary highlights key accomplishments and challenges from the previous housing element’s planning period (2015 to 2022). This information will help ensure that the updated element for 2023 to 2031 builds on success, responds to lessons learned and positions us to better achieve our community’s housing priorities.

A more detailed program-by-program review of progress and performance is in Table HE -36.

Accomplishments
As noted in Section 3.620, ADUs have become increasingly popular after the Town adopted amendments to the ADU ordinance. Prominent Ordinance revisions support this increased production trend from prior years as prescribed by Government Code Sections 65852.2 and 65852.22. ADUs are a Town asset in accomplishing RHNA goals and providing more affordable housing units for low-income and special needs populations.

The Town’s approval of dormitory housing for Menlo College contributed to the market-rate and below market-rate units in the Town of Atherton. Not only does dormitory housing provide additional housing options for students, but it also alleviates the student-demand for other units and frees up non-dormitory housing for other Town residents.

Challenges
While the Town has several achievements, there is still work to be done. Some of the challenges that kept the Town from achieving all of its housing goals include:
• The Town does not have any commercial activity – which means there are no retail sales taxes, commercial development impact fees or other related sources of revenue available to other cities. The Town has very restricted tax revenue. This restricts the option of financial incentives or participation by the Town in building new and affordable housing.
• During the 2015-2022 Planning Period, it was anticipated that new housing would be constructed at Menlo School and Menlo College. A net of eleven new faculty units affordable to very low- and moderate-income households were planned at Menlo School and 79 new units affordable to lower income and moderate-income households were planned at Menlo College. Although the plans for these units remain on the Master Plans for these institutions there were insufficient funds available to construct them during the Planning Period.

It is recommended that this program be carried forward to the 2023-2031 Planning Period.

Ongoing Efforts
The Town continues to move forward with its goals and actions outlined in the prior cycle’s Housing Element. In addition, the trends and lessons learned from the prior cycle have been thoroughly analyzed and considered for effective incorporation in this Sixth Cycle Housing Element. These include:

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
143
• Imposition of an affordable housing impact fee on single family building permits to fund programs to assist in development and assistance for affordable housing.
• Implementation and promotion of SB 9 lot splits.
• Expansion of ADU programs through the consideration of various development and incentive programs.
• Amendment of PFS zoning to permit multi-family housing by right • Creation of a new multi–family zoning district RM 10
• Adoption of a new affordable housing Inclusionary Ordinance The following describes how the objectives and programs of the 5th Cycle Housing Element will be updated and how changes will be incorporated resulting from the evaluation.

The program of providing new construction of Above-Moderate income units has, in the past, depended on the construction of single-family detached homes throughout the Town’s R1-A and R1-B lots. The program has been hampered by the lack of available land and the low-density character of the community. New construction invariably results in the demolition of an existing unit, leading to nearly a net zero increase in housing units. The adoption and implementation of SB 9 by the State of California is projected to allow the creation of additional lots with higher densities and thus permit the development of a greater number of Above-Moderate housing units during the 2023-31 planning period. Further, the Town will create two new multi-family zoning districts, RM 20 and RM 10 that will facilitate the development of additional above-moderate income units.

Program 3.712: New Construction of Affordable Units - The program of providing new construction of affordable units has, in the past, depended primarily on the construction of ADUs and JADUs. While the objective was met in the 2015-22 planning period, the RHNA objectives for 2023-31 is markedly higher.

Consequently the 2023-31 Update includes Housing Program 3.813 addressing multifamily housing development on school and other properties and creation of two new multifamily zoning districts, RM 20 and RM 10 that will be applied to several properties. In addition, an Inclusionary Zoning Ordinance will be adopted which requires a percentage of units to be set aside for lower-income housing. These new programs should be sufficient to meet the 2023-2031 objectives for affordable units.

Program 3.712a: Conduct Affordability Surveys - While housing affordability surveys during the 2015-22 planning period have been required as a condition of approval,

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
144
they typically reflect anticipated rent, and therefore affordability, as opposed to actual affordability. Changes in the 2023-31 Update are proposed that require a survey every two years of actual rents in order to determine the actual affordability level of low and moderate income ADUs, JADUs, multifamily and other known affordable units. This change will provide data that can be used to adjust programs during the planning period, if necessary.

Program 3.712b: Faculty and Student Housing – The program of providing additional faculty and student housing on or near school campuses and there appears to be a desire on the part of the schools to construct additional faculty and student housing.

The 2023-2031 Update includes new programs such as Inclusionary Zoning Ordinance that could assist in funding construction and zoning changes such as increased height, reduction of setbacks and similar changes that could allow increased densities, all helping to reduce barriers to development of new faculty and student housing.

Program 3.712c: Maintain Contact with Affordable Housing Developers – Atherton management and planning staff have regular contact with developers of affordable housing, exchanging ideas and proposals about expanding affordable housing opportunities in Atherton. This program continues into the 2023-31 planning period in order to take advantage of affordable housing opportunities as they arise.

Program 3.713: Conservation and Rehabilitation of Existing Units -– The Atherton Planning Department works closely with the Building Department to encourage the conservation and rehabilitation of housing in Town, with particular attention to affordable housing. The Town will continue to assist the property owners and development community in the housing development, conservation and rehabilitation process. The Town will establish a building inspector ombudsman to assist property owners navigate the rehabilitation process. This program continues into the 2023-31 planning period with a projected 50 to 100 permits being issued for improvement, rehabilitation and conservation projects.

Program 3.720: Special Housing Needs
Program 3.721: Seniors – The Town has a number of programs supportive of Seniors.

These programs include permitting residential care facilities and providing information on home repairs assistance and the Property Tax Postponement Program. The Town will continue these programs and others, in support of senior populations in the 2023- 2031 Housing Element.

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
145
Program 3.722: Disabled and Developmentally Delayed Persons – The Town has a number of programs supportive of persons with disabilities. These programs include, enforcing ADA compliance in new residential developments and major remodels, providing referrals and information to the County’s Housing Accessibility for Disabled Persons Program, and providing information on housing and services for persons with developmental disabilities. These programs will continue in the 2023-2031 Housing Element.

Program 3.723: Equal Housing Opportunity – The Town will continue to refer housing discrimination complaints to the appropriate groups, as well as disseminate fair housing information at Town Hall and on the Town website. The 2023-2031 Housing Element will include additional program elements that expand on the implementation of the outreach campaign, zoning code amendments, adoption of an affordable housing impact fee, increase awareness of equal housing resources for eligible population and increase the number of housing available to lower income renters/residents.

Program 3.724: Emergency Shelters, Transitional and Supportive Housing – The Town will continue to support the possibility of Emergency Shelters, Transitional Housing, and Supportive Housing in Atherton. The 2023-2031 Housing Element will also include a program expanding on the protocol in the event such housing is needed.

Program 3.730: Consistency with State Requirements
Program 3.731(a-c): Energy Conservation – The Town has regulations that encourage energy conservation. These regulations include permitting solar installations, and promoting through various public education programs, energy efficient design. The Town also requires native landscaping to the greatest extent feasible, which reduces the need for both water and energy. All of these policies and regulations will continue.

Program 3.731d: Employee Housing – The Town will continue to ensure compliance with State Health and Safety Code Sections 17021.5. Furthermore, the Town will expand on this program and the code will be revised consistent with Section 17021.6.

Program 3.740: Other Housing Programs
Program 3.741: Shared Housing – The Town will continue to support the Human Investment Program (HIP) and continue to make information available at Town Hall and on the Town website. This program will continue into the next planning cycle. The Town will include additional housing programs in the 2023-2031 Housing Element. These are reflected in Section 3.800.

Cumulative Evaluation of Effectiveness of 5th Cycle Element in Addressing Special Housing Needs
The State Department of Housing and Community Development has requested that the Town “analyze the cumulative effectiveness of the previous Housing Element goals, policies, and programs on special needs populations (e.g., elderly, persons with disabilities, large households, female-headed households, farmworkers, and persons experiencing homelessness).”
Of the special needs populations, the 5th Cycle Housing Element particularly focused on seniors, who make up 22.4% of Atherton’s population. There were four programs specific to seniors (Program 3.721a-3.721d). These were related to residential care facilities, home repairs assistance, property tax postponement, and creating a senior friendly plan. The last program was not implemented due to lack of funding and interest in this type of program. The first three programs however, were implemented and are continued into the 2023-2031 Housing Element. Many older Atherton residents have been able to age in place, modify their homes, and continue living in the Town as a result of these programs and policies. Understanding how seniors might be costburdened is of particular importance due to their special housing needs, particularly for low-income seniors. Senior households often experience a combination of factors that can make accessing or keeping affordable housing a challenge. They often live on fixed incomes and are more likely to have disabilities, chronic health conditions, and/or reduced mobility. The 2023-2031 Housing Element supports diverse housing options that allow senior households to have more mobility as well as programs that support seniors in maintaining their homes.

There were three programs specific to disable and developmentally delayed persons in the 5th Cycle Housing Element (Program 3.722a-3.722c). People with disabilities can face additional housing challenges. Encompassing a broad group of individuals living with a variety of physical, cognitive, and sensory impairments, many people with disabilities live on fixed incomes and need specialized care, yet often rely on family members for assistance due to the high cost of care. The three programs were implemented and are continued into the 2023-2031 Housing Element.

In the 2022 San Mateo County One Day Homeless Count and Survey, there were 3 homeless individuals counted in Atherton, less than 1% of the Town’s population.

Atherton historically has one of the lower homeless counts in San Mateo County.

Shelters and homeless assistance programs are the main resources available to homeless residents of San Mateo County. Program 3.724a of the 5th Cycle Housing

Element supports the facilitation of interested developers pursuing Emergency Shelters, Transitional Housing, and Supportive Housing in Atherton.

Large family households often have special housing needs due to a lack of adequately sized affordable housing available. In Atherton 13% of households are large households with five or more people sharing the same income. The higher costs required for homes with multiple bedrooms can result in larger families experiencing a disproportionate cost burden than the rest of the population and can increase the risk of housing insecurity.The 2023-2031 Housing Element facilitates the development of multifamily housing, as well as SB 9 lot splits and ADUs, that provide a variety of housing options for large family households.

In Atherton, 5.4% of households are female-headed households with children present (i.e., a household unit with one female head of house only, and at least one person under 18 years of age). Households headed by one person are often at greater risk of housing insecurity, particularly female-headed households, who may be supporting children or a family with only one income. Difficulty in finding affordable housing can result in disproportionate cost burden on female headed families compared to the rest of the population and can also increase the risk of housing insecurity. The 2023-2031 Housing Element includes programming that supports HIP Housing in facilitating secure housing for female-headed households.

All of these factors were considered in the evaluation of related programs from the past cycle and informed the recommendations as noted below in Section 3.640, as well as the development of new programs in Section 3.800.

The Town’s 5th Cycle Housing Element included specific goals addressing the needs of seniors, disabled persons, and homeless (emergency shelters). Cumulatively, these measures have contributed to the health, safety, and welfare of all Atherton residents and to the quality of life and condition of housing in the town. However, the 5th Cycle could have been better in including programs addressing the needs of the remaining special needs populations, including large households and female-headed households. There were the affordable housing programs (Program 3.712), one program related to Equal Housing Opportunity (Program 3.723a), and one program related to Shared Housing (Program 3.741a). The Town will expand its programs related to special needs populations in the 6th Cycle Element by doing the following:
• Expanding the programs related to Equal Housing Opportunity with eight additional programs.
• Continuing the program to support the possibility of Emergency Shelters, Transitional Housing, and Supportive Housing in Atherton from the 5th Cycle

Element (Program 3.724a), and expanding the specifics of this with an additional program in the 6th Cycle Element.

TABLE HE - 38: SIXTH CYCLE PROGRAMS AND OBJECTIVES
Name of Program Objective
Program 3.810: New Construction, Conservation and Rehabilitation

3.811 (A) New Single
Family Housing
Development
Continue to facilitate and expediate the development of new singlefamily housing units.

Timeframe: Ongoing
Agency Responsible: Planning Department
Funding Sources: General Fund
Reason for Edit: No need to give a quantified objective for this category separate from the Quantified Objectives Table HE-37

3.811 (B) New Single
Family Housing
Development from
SB9 Implementation
The Town adopted an SB9 ordinance consistent with State Law provisions in 2022. The Town projects approximately 48 new above moderate-income housing units to result from lot splits and new housing facilitated by SB9 (24 completed lot splits).

Atherton has already completed 6 recorded SB 9 lot splits and has 3 more currently under review. If, at mid-cycle (late 2027) there are identified constraints on SB 9 lot splits, the Planning Department will prepare an ordinance to further incentivize lot splits with fee waivers, prioritized review, or other incentives. The ordinance will be presented to Council by August 2028, if necessary.

Timeframe: Ongoing, with mid-cycle check-in late 2027 that could result in a revised ordinance presented to Council by August 2028, if applicable.

Agency Responsible: Planning Department
Funding Sources: General Fund
AFFH Metric: 24 SB 9 lot splits completed and two above-moderate units on each lot split during the planning period, for 48 new above moderate income units
Addresses AFFH Issue C: High land acquisition Cost
Reason for Edit Committing to an AFFH metric to meet HCD requirements and adding a mid-cycle check-in to support furthering the AFFH metric

3.811 (C) New MultiFamily Housing
Development
The Town will adopt RM-10, RM-20, and RM-40 multifamily residential overlays that allow a maximum of 10 du/ac, 20 du/ac, and 40 du/ac, respectively. These overlays will cover sites that permit by-right multifamily development per the Objective Design Standards

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
163
adopted concurrently to the overlay zones. The Town projects at least 96 multifamily housing units to be developed through this program.

The Objective Design Standards will be adopted after substantial input from the affordable housing development community as well as the Atherton community. In addition to by-right development, multifamily housing will be incentivized with:
• Prioritized development review
• Reduced fees
• Financial support from SFR Impact Fees (Program 3.823 (D)) and Inclusionary Fees (Program 3.814) for affordable housing developments
This would allow multifamily rental housing in Atherton for the first time in the Town’s history. The General Plan land use designations will be amended to facilitate multifamily residential development, as appropriate.

This program will rezone to accommodate a minimum of 22 lower income units on a maximum of 1.1 acres (22 units at 20 du/ac). The program would require sites identified for rezoning to meet the following requirements:
• Permit owner-occupied and rental multi-family uses by-right in which 20% or more of the units are affordable to lower
income households
• Permit a minimum density of 20 units per acre
• Allow a minimum of 16 units per site
• Accommodate at least 50 percent of the lower income need on sites designated for residential use only, otherwise allow 100% residential use and require residential to occupy at least 50% of the floor area in a mixed-use project.

Timeframe: Objective Design Standards are initiated and the Town is considering expanding the sites identified in the adopted housing element. The Objective Design Standards and rezoning will be adopted by the end of 2024.

Agency Responsible: Planning Department, Planning Commission, City Council, City Manager
Funding Sources: General Fund
AFFH Metric: Facilitate the development of at least 96 units at the following affordability levels on sites with RM-20 and RM-40 overlay zoning:
• Very Low Income: 57 units

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
164
• Low Income: 14 units
• Moderate Income: 25 units
• Above Moderate Income: 0 units
In addition, facilitate the development of up to 95 units of multifamily residential housing on sites with RM-10 overlay zoning.

Addresses AFFH Issue A: Lack of housing that accommodates lower income households
Addresses AFFH Issue B: Predominance of single-family housing Addresses AFFH Issue C: High land acquisition Cost
Reason for Edit:

Committing to an AFFH metric to meet HCD requirements and clarifying the connection between rezoning and Objective Design Standards

3.811(D) Mid-Cycle
Check-In
The Town will review development on RM-10 multi-family residential overlay sites at the end of December 2026. If fewer than four of the 11 sites have development or active development proposals at that time, the Town will modify its zoning mid-cycle to allow additional multifamily development. This could include:
• Identification of at least three new RM-10 multifamily residential overlay sites
• Adoption of an SB 10 overlay that allows at least three identified sites to be developed with up to 10 units and a process for individual property owners to apply for an SB 10 overlay on their property
• A different rezoning that would allow additional housing mobility, including multifamily housing, in Atherton
If this action is necessary, City Council will adopt this mid-cycle rezoning by the end of December 2027, to be effective in January 2028.

Timeframe: Review of development by end of December 2026. New strategy, if necessary, to be adopted by City Council by end of December 2027, to go into effect in January 2028.

Town of Atherton 2023-2031 Housing Element – DRAFT
September 2024
165
Reason for Inclusion: Per preliminary HCD feedback received on September 9, 2024, the Town’s RM-10 strategy requires additional monitoring and alternative actions to meet HCD requirements.

3.812 (A) New
Construction of
Affordable
Accessory Dwelling
Units
Continue to encourage the development of ADUs and approve ADUs ministerially in conformance with State Law provisions. The Town projects ADU development at a rate of 26 new ADUs per year, for a total of 280 during the planning period. The Town projects that 124 ADUs will be available to very low- and low-income households and 62 ADUs will be available to moderate income households.

The Town has not identified any constraints to ADU construction. ADU plans are approved ministerially with minimal objective design standards, the Town does not impose impact fees and, given the large size of Atherton properties, there is adequate land available to build attached and detached ADUs and JADUs.

The Town will take the following actions to further incentivize ADU production:
• Amend the zoning code to allow pool houses and guest
houses to be rented as ADUs (there is currently a 30-day occupancy per year limit). The Town will distribute a town wide mailer informing property owners of this change and encouraging rental of their units. (December 2024)
• Adopt a program for pre-approval of ADUs plans to
streamline the review and approval process and reduce the cost to prepare detailed plans. (June 2025)
The Town will take the following actions to further improve outreach regarding ADU construction:
• Distribute, at least annually, community outreach mailing and social media posts (Annually, first by end of 2024)
• Host at least one community workshop on new ADU
development standards during the planning period
(December 2027)
• Provide information on the Town’s website and at the Town counters on the ease of ADU development. (December 2024) • Distribute a Town-wide mailer to create an inventory of existing pool houses and guest houses. Using this inventory, the Town would work with a non-profit (HIP) to connect
homeowners to prospective renters (see program 3.812 (B):

ADU Rentals) (Distribute by March 2025, create inventory by September 2025 and initiate collaboration by December
2025)

Town of Atherton 2023-2031 Housing Element – DRAFT

AFFH Metric: Development of 208 ADUs by the end of the planning period. Outreach goals include: 7 mailers, 1 workshop, 1 complete inventory of pool and guest houses
Addresses AFFH Issue A: Lack of housing that accommodates lower income households
Addresses AFFH Issue B: Predominance of single-family housing Reason for Edit:

Committing to an AFFH metric to meet HCD requirements; Providing more detail to HCD on steps and timing to incentivize ADUs and provide additional outreach; Bringing in previous Program 3.845 to improve ease of implementation of program (no two separate programs on same issue)

3.812 (B) Affordable
ADU Rentals
The Town will take the following actions to further incentivize belowmarket-rate rentals of ADUs:
• The Town will continue to request the owner fill out an ADU rental survey indicating the amount of rent to be charged for the unit at the time of construction or conversion. By
comparing this rent to the San Mateo County monthly
maximum affordable housing cost by household chart, the affordability level of each unit is determined.
• To encourage rental of ADUs and JADUs, the Town will
develop a comprehensive incentive ADU/JADU rental
program and partner with a non-profit organization (HIP) to facilitate the rental advertising, screening and partnering process.

Amend the zoning code to allow two ADUs to be constructed on a property if the second ADU is deed-restricted to a lower-income household for 10 to 15 years, depending on availability. The deedrestricted ADU would be exempt from ADU floor-area limitations, and could be a detached unit or attached to the principal dwelling, a garage, or another ADU. This would only be applicable on lots that are 2 acres or larger.

PROMOTING HOUSING MOBILITY
In addition to meeting RHNA through quantified objectives, as shown in Table HE-37, Atherton has several housing element AFFH-focused programs that promote housing mobility by improving equitable access to opportunity, addressing Atherton’s fair housing issues as defined in Section 3.390: Fair Housing Issues, Contributing Factors, and Town Actions. Promoting housing mobility primarily improves Fair Housing Issues A (lack of lowerincome housing) and B (diversity of housing types). Fair Housing Issue C (high land acquisition cost) is a lower priority and programs addressing this fair housing issue can enable more productive programming options for future cycles, as there are simply few opportunities for a small jurisdiction to mitigate the high land acquisition costs within its boundaries.

Due to the small size of the town and lack of distinguishing fair housing characteristics between its neighborhoods, there is no program-by-program geographic targeting.

Some programs (such as multi-family residential overlays and SB 9 lot splits) target specific parcels and will have a neighborhood effect. But because the fair housing issues are so acute throughout the town, as described in sections 3.320 through 3.380, there is no area of Atherton that requires more mitigation than other areas of the town.

Through Program 3.811 (C), the Town is committed to facilitating the development of 96 multifamily units at the following affordability levels:
• 57 for Very Low income
• 14 for Low income
• 25 for Moderate Income
Other notable programs with specific commitments towards promoting housing mobility, increasing housing choice and affordability throughout the city, include:
• Program 3.811 (B) – SB 9 Implementation: 24 SB 9 lot splits • Program 3.812 (A) – ADU Construction: 208 ADUs to be developed (186 affordable units and 22 market-rate units)
• Program 3.812 (B) – Deed-Restricted ADUs: 18 ADUs deed-restricted to lowerincome households (as part of 186 affordable units identified in Program 3.812 (A))
• Program 3.815 – Unit Rehabilitation: 4 rehabilitated units • §Program 3.841 – Shared Housing: 8 shared home agreements

3.900 EFFORTS TO ACHIEVE COMMUNITY ENGAGEMENT
Extensive public engagement is an essential component to the housing element update process. During this Planning Period, Atherton held several public meetings to discuss the proposed strategies with the community. The Town also partnered with 21 Elements and the Let’s Talk Housing effort to engage with current and potential beneficiaries of housing programs and services and their advocates (e.g., lower income representatives, tenants of affordable complexes, groups targeted for special housing needs consideration, community-based organizations, health and human service providers, homeless shelter and service providers) in the update process. The participation of development professionals including local buildings, for and nonprofit developers, architects, trade labor unions, realtors, mortgage bankers and brokers, areas lenders and others have been invited to participate.

The Town also created a Housing Element webpage to advertise meetings, post resources, the Draft Housing Element and a portal to provide public comments.

The community outreach effort coordinated with 21 Elements included virtual community meetings and webinars on the following topics: Introduction to the Housing Element, All About RHNA Webinar, Stakeholder Listening Sessions and Creating an Affordable Future webinars (four-part series).

In addition to the 21 Elements coordinated outreach efforts, the Town held several public meetings to discuss Housing Element programs, policies and strategies as follows:
• City Council meeting on November 4, 2020 to discuss the RHNA allocation process.
• A Joint meeting with the Planning Commission and City Council was held on April 28, 2021 to discuss key strategies to meet the RHNA obligation. • City Council meeting held on January 12, 2022 to refine the housing element strategies.
• City Council meeting on February 24, 2022 to discuss the housing element strategies.
• City Council meeting on March 16, 2022 to discuss the housing element strategies.
• City Council meeting on May 18, 2022 to review comments from the community outreach meeting and further discuss the housing element strategies.
• Special City Council meeting on May 24, 2022 to provide further direction on the housing element strategies.

The Town held a public engagement/discussion meeting in the evening on April 26, 2022.

A special edition of the Town newsletter was prepared and physically mailed to every address in Town describing the proposed Housing Element programs and announcing the community meeting. The event was also promoted through the Town’s email newsletter list, Town website and posted at the Town’s Civic Center. Approximately 60 community members attended. An open discussion/engagement format was used rather than the typical presentation/public hearing and response format. Community leaders (City Council members and others) mixed with community members to discuss a wide variety of housing issues. Some engagement issues included:
• Education on the magnitude of the challenge facing the Town, the need for collaborative solutions, and the impact of non-compliance. • Issues relating to a proposed multifamily overlay zone, proposed locations and details about the zoning district.
• Some community members truly want to solve the housing problem by adding or registering their ADU or JADU.
• Other community members were interested in being a part of the proposed multifamily overlay zone.
• Questions were raised about how the multifamily overlay zone works for numbers of units produced.
• Better definition of how a density bonus works.
• There were concerns raised about aesthetics and design, however that was not a primary issue for most.
• There was a lingering issue about diminished property values; single-family home adjacent to multifamily complex.

The meeting eventually transitioned to a question-and-answer format, which was helpful, but only after an extensive engagement format which provided an opportunity for education and discussion.

Key lessons from the meeting were that senior housing is an important topic for residents.

Many residents feel passionately that they want to continue to live in Atherton as they age. Some are worried that their current houses do not meet their needs and are looking for options to stay.

The Draft Housing Element was published on the Town’s website for a 30-day public review and comment period on June 10, 2022. Notice of the availability of the document was provided via email to Housing Advocates, published in the Almanac Newspaper and announced to residents via the Town’s e-notify system and social media outlets. The City Council, at its June 15, 2022 regular meeting discussed comments they have received individually and provided an opportunity for the public to provide comments.

During the 30-day public review period, the Planning Commission held a Special meeting on June 23, 2022 to receive comments from Commissioners and the public. The Town received over 300 written comments on the Draft Housing Element in addition to verbal comments provided at the meetings listed above.

At the July 20, 2022 City Council meeting, the Council discussed public comments received on the Draft Housing Element and directed staff to revise the Draft Housing Element to incorporate public feedback. Specifically, with respect to the overwhelming public comments in opposition of the multi-family overlay concept, the Council directed this program be removed from the Element. Council also requested revisions to several housing programs as suggested by the Housing Leadership Council, including expanding the Accessory Dwelling Unit program.

The City Council, at its July 27, 2022 Special meeting reviewed the revised Draft Housing Element and authorized transmission to HCD for its preliminary review and comments.

Public meetings on the housing element were re-initiated in 2024. A Planning Commission/ City Council workshop was held on April 29, 2024 to discuss new revisions regarding sections 3.100, 3.200, 3.300, and 3.600 – focusing on issues of feasibility, fair housing, and geographic equity. An additional ADU-focused workshop took place on May 20, 2024. The revised housing element (including revisions directed at the April 29 and May 20 meetings) was presented to Planning Commission on July 24, 2024 and August 28, 2024 for recommendation on adoption alongside Zoning Code changes and new Inclusionary requirements. These documents were then brought to City Council for adoption on September 18, 2024.

Re: Town of Atherton Adopted Housing Element
Please find herein the Town of Atherton’s Housing Element for the 2023-31 period (Sixth Cycle). The City Council found that the Housing Element substantial complies with Housing Element laws, and on that basis, certified and adopted the Housing Element on January 31, 2023 and directed staff to submit the document to the State. The Town believes that it has made a good faith effort to address the Regional Housing Needs Allocation with a creative yet comprehensive plan that considers the uniqueness of this community.

Atherton is a 100% built-out community with limited needs and resources. Plus, property owners have unequivocally expressed that they will neither sell their property nor develop them into multifamily lots. However, they committed to the construction of Senate Bill 9 lots (and the Town has received much interest) and Accessory Dwelling Units (with the Town seeing actual ADUs being built and requests for more). Based on this untenable position, but mindful of its obligations to plan for its RHNA, the Town found that upzoning existing, built-out, properties would not result in those properties actually being developed into multifamily units. Unlike other communities, the Town also has extremely limited public property, all of which is either built out (civic center, police station, small corporation yard) or gifted to it and under deed restrictions for use (Holbrook-Palmer park). In other words, planning for Atherton's RHNA is incomparable to other communities and required creative solutions.

As such, the 6th Cycle Housing Element addresses the identified needs of the community using upzoning in portions of the Town where property owners have expressed interest, along with a combination of accessory dwelling units, lot splits pursuant to Senate Bill 9, vacant lot development.

This solution provides a distributed approach in a way that best prevents segregation, racial or ethnic concentration of housing, or results in a disparate impact to access or opportunities for housing.

Specifically, the adopting Housing Element implements goals, policies and programs to incentivize and promote adequate housing opportunities for people at all income levels. For example, it includes:
• Upzoning at Menlo College to allow affordable housing for students and teachers. The college has committed to a "centennial campaign" that is already underway and states that local donors have committed to contributing the necessary funds to actually design a four story 40-60 unit multifamily complex. (See Appendix 6). This demonstrates not just planning for additional housing, but seeking commitments to effectuate its construction; Town of Atherton

• Upzoning at 23 Oakwood to allow 10 dwelling units/acre with a 20% affordability requirement to result in the construction of up to 16 new units. (See, Housing Element at p. 68-69).

Furthermore, similar to Menlo College, the Town obtained a willingness and commitment from the property owner to actually develop. (See Appendix 7); • Local policies to incentivize ADU development and rental programs to facilitate affordable housing, including, but not limited to, partnering with HIP housing, allowing multiple ADUs on parcels that are at least 2 acres, and offering fee reductions; • Streamline the construction of affordable housing by offered an expedited review process • Adopting an affordable housing fee, which fees will be used to provide rental assistance for very-low income housing.

To comply with public participation requirements pursuant to AB 215 (Chapter 342, Statutes of 2021), a draft of this document was made available for public comment on January 23, 2023 with copies provided to individuals and organization who previously requested copies. The draft was posted on the Town’s website and physical copies made available at Town Hall and the Library. The Town exceeded the minimum public participation requirements by establishing additional workshops, community meetings, and multiple public hearings to solicit public comment. The Housing Element was promoted via the Town’s email newsletter, public notices posted at the Town Center, public notification in the newspaper, email outreach to interested parties, and physical mailings to affected properties. The Atherton City Council reviewed public comments received during the public review period at its January 31, 2023 meeting, directed specific modifications in response to public comments, and authorized transmittal of the then adopted and certified Housing Element to HCD. The final version of the Housing Element has also been posted on the website with copies provided to interested parties.

Thank you for your time and attention in reviewing this document.

3.000 HOUSING ELEMENT (2023-2031 UPDATE)

3.100 INTRODUCTION

3.110 Purpose of the Housing Element
The State of California Government Code1 requires that all cities within the San Francisco Bay Area update the Housing Element of their General Plan by January 31, 2023. The purpose of this document is to meet this requirement by evaluating the existing and projected housing needs of all economic segments of Atherton, evaluating existing policies and programs aimed at the preservation, improvement and development of housing and where appropriate, identifying new priorities.

The contents of this update include an analysis of housing needs, statements of goals and policies, a schedule of programs and actions and an estimate of the number of housing units the Town expects to be developed, improved and maintained in the local housing stock. Programs and policies included in the existing Housing Element were evaluated and modified where necessary to reflect changing market conditions and policy priorities.

Atherton is a residential community of approximately 7,200 residents with a land area of approximately six square miles. The Town is bordered by Menlo Park, Woodside, Redwood City and unincorporated San Mateo County. Founded in the early 1920’s, Atherton is characterized by large lot residential land use, where minimum lot size is 1/3 to 1 acre throughout the Town. There is no commercial or industrial land use in Atherton.

There are eight schools in Town, three of which are private.

3.120 Definition of Income Categories
Since the determination of housing need is often discussed in terms of income categories, it is important to define the categories used in this update at the outset. The California Department of Housing and Community Development (HCD) has established household income categories based on a proportion of the area’s median family income as summarized below:

TABLE HE-1: HCD INCOME CATEGORIES DEFINED
Income Category Definitions
Acutely Low 0 – 15% of area median income
Extremely Low 15% - 30% of area median income
Very Low 30%-50% of area median income

3.130 RHNA (Regional Housing Needs Allocation) 2023 - 2031 (6th Cycle) The Regional Housing Needs Allocation in the Bay Area is a process managed by ABAG (Association of Bay Area Governments) and MTC (Metropolitan Transportation Commission), whereby the housing needs for the Bay Area are distributed to the various County and city jurisdictions. The 2023 - 2031 period is the 6th RHNA cycle since the beginning of the process. The Town of Atherton has been assigned the allocations by income category, listed below for this cycle:

Very Low Income 94 dwelling units
Low Income 54 dwelling units
Moderate Income 56 dwelling units
Above Moderate Income 144 dwelling units

3.140 Relation to Other Elements (including General Plan Consistency Analysis) The Housing Element is closely related to the Land Use, Open Space and Circulation Elements. In the Housing Element, residential land use is translated into terms of household units to be accommodated in the future. Lands designated for residential use are identified in the Land Use Element; the location, site area and terrain suitable for housing is related to both open space and land use; and the capability of serving residential neighborhoods by an efficient circulation system is discussed in the Circulation Element.

State law requires that all elements of the general plan be consistent with each other.

The General Plan was reviewed to ensure that the goals and policies of this Housing Element are consistent with the other elements of the Town’s General Plan

3.200 ASSESSMENT OF HOUSING NEEDS

3.210 Housing Needs Detailed Analysis
See Appendix for detailed Housing Needs Analysis.

3.211 Summary of Key Facts
People
● Population – Unlike the rest of the Bay Area, Atherton’s population has been declining. The Town’s population decreased by 2.3% from 2000-2020, while both the county and the Bay Area’s populations have increased (by 9% and 15% respectively). In Atherton, this has been the result of almost complete buildout of the Town in accordance with the General Plan, aging population, and policies that restrict land use to low density residential and minimum lot sizes to 1 acre or ⅓ acre. This increase throughout the region is mostly due to natural growth (births minus deaths) and a strong economy drawing new residents to the region. ● Income – Atherton has a lower percentage of lower income households than the rest of the county and region, with 17% of households earning less than 80% of the Area Median Income (AMI)3 compared to 40% of households in San Mateo County and 39% of households in the Bay Area as a whole. Of those that are considered lower income in Atherton, approximately 6% are considered very low-income (earning less than 50% of AMI) and 6.5% are considered extremely low income (earning less than 30% of AMI).
● Age – Community members in Atherton are overall older than they were in the past. The median age has increased from 45.2 in 2000 to 47 in 2019. In 2019, 22.3% of the population was under 18 and 22.4% was over 65.
● Race/Ethnicity – Atherton is less diverse than the Bay Area as a whole. In 2019, 69% of the population was White, 21% was Asian, 4.4% was Latinx, and 0.8% was African American (see chart).
● Poverty – Currently, people of color in San Mateo County are more likely to experience poverty. The group with the highest poverty rate in Atherton is 3 The Area Median Income is the middle spot between the lowest and highest incomes earned.

The AMI for the county is $104,700 for a single person, $119,700 for a household of two and $149,600 for a family of four.

5-Year Data (2015-2019), Table B03002.

Jobs
● Employment – Generally, having a similar number of jobs and employed residents produces more benefits for a community, such as reducing traffic and climate impacts, and allowing people who work in the community to also live there. San Mateo County is job rich, meaning it has more jobs than employed residents.

In contrast, Atherton is job poor. Based on ABAG/MTC data, of 7,200 residents there are 2,870 employed residents and 2,726 jobs5 in Atherton, resulting in a jobsto-resident-workers ratio of 0.95. However, the estimation of jobs likely includes commercial enterprises within the nearby County-unincorporated area as the Town has no commercial land use. The Town believes that a more accurate number for jobs in Atherton is far less and has advised ABAG/MTC of this concern during each Plan Bay Area review. Actual jobs with physical locations in Atherton are limited to Town employees, public and private school employees, country club employees and CalWater employees. There are, however, a number of service industry jobs that are located in Atherton, such as construction, delivery, and household. Unfortunately there is no data readily available to more accurately represent local jobs.
4Some demographic groups do not have reported poverty rates or may have over/underestimated rates as a result of having a limited sample for the particular group. 5 Employed residents in a jurisdiction are counted by place of residence (they may work elsewhere) while jobs in a jurisdiction are counted by place of work (they may live elsewhere).

● Unemployment – Jurisdictions throughout the region experienced a sharp rise in unemployment in 2020 due to impacts related to the COVID-19 pandemic, though with a general improvement and recovery in the later months of 2020. As of January 2021, Atherton’s unemployment rate was 6.1%, which was slightly lower than the regional unemployment rate of 6.6% and much lower than its pandemicrelated high rate of 14.6% in April 2020. Atherton’s pre-pandemic unemployment rate was 2.8% (January 2020). (Source: California Employment Development Department, Local Area Unemployment Statistics (LAUS), Sub-county areas monthly updates, 2010-2021).

Housing and Households
● New Homes Built – The number of new homes built in the Bay Area has not kept pace with the demand, resulting in longer commutes, increasing prices, and exacerbating issues of displacement and homelessness. The number of homes constructed in Atherton decreased 1% from 2010 to 2020, which is below the growth rate for San Mateo County and below the housing growth rate of the region’s housing stock during this period (4% and 5% respectively). ● Home Prices and Rents –
Housing prices in Atherton are
not seen as affordable to most
residents and workers in the
region. Given high job growth
and low housing growth in the
county, the cost of housing in
Atherton has increased
significantly in the past decade:
o Sales Price – In 2020, the average sales price of a single-family home in Atherton was approximately $7,897,800. Home prices increased by 196% from 2010 to 2020.6
o Rental Prices – Rental prices increased by 60% from 2009 to 2019. The median rent in 2019 was $3,200. To rent a typical apartment without cost burden, a household would need to make $128,320 per year.7 6 San Mateo Association of REALTORS Annual Reports 2010-2020 7 Note that contract rents may differ significantly from, and often being lower than, current listing prices.

January 2023
● Housing Type – In 2020, 98% of homes in Atherton were single family detached, 2% were single family attached, 0.2% were small multifamily (2-4 units), and 0% were medium or large multifamily (5+ units). Atherton’s housing consists of more detached single-family homes than the region as a whole (98% as compared to 52% in the Bay Area).
● Housing for Large Families - Large families are generally served by homes with 3 or more bedrooms, of which there are 2,093 units in Atherton (94% of the housing).

Among these 3+ bedroom units, 6% are renter-occupied and 94% are owneroccupied. ● Cost Burden – The U.S. Department of Housing and Urban Development (HUD) considers housing to be affordable for a household if the household spends less than 30% of its income on housing costs. A household is considered “costburdened” if it spends more than 30% of its monthly income on housing costs.

Those who spend more than 50% of their income on housing costs are considered “severely cost-burdened.” In Atherton, 14% of households are cost burdened, while an additional 18% of households are severely cost burdened. ● Neighborhood Equity – Some neighborhoods are identified as “Highest Resource” or “High Resource” by the State of California based on a range of indicators such as access to community resources–quality schools, proximity to jobs and economic opportunities, low pollution levels, and other factors.8 Neighborhoods do not always receive an equitable share of these community resources and may be designated as “Low Resource” if they lack these amenities. Approximately 40% of residents in Atherton live in neighborhoods identified as “Highest Resource” or “High Resource”, while no residents live in areas identified by this research as “Low Resource”.
● Displacement & Gentrification – Displacement, or the inability of residents to afford to remain in their homes, is a major concern in the Bay Area due to increasing housing prices. Displacement has the most severe impacts on low- and moderateincome residents. When individuals or families are forced to leave their homes and communities, they lose their support network. A related concern is the impact of gentrification or exclusion—when neighborhoods have limited or no housing opportunities for low- and moderate-income residents.

Town of Atherton 2023-2031 Housing Element – DRAFT 11
January 2023
Low-income households are excluded from virtually all of Atherton's neighborhoods due to the high cost of land. The notable exception to this is accessory dwelling units (ADUs) and junior ADUs (JADUs) throughout town. The Town supports and encourages an active and successful home-sharing program through HIP Housing. Lastly, Menlo College provides extensive dormitory use for students that would otherwise be housed and renting affordable units off campus.

By supporting multi-family housing on campus, the Town is able to assist in opening up scarce affordable housing resources throughout the region. ● Special Housing Needs – Some population groups may have special housing needs such as mobility and accessibility barriers. For instance, individuals with disabilities are often unable to work and live off of a fixed income, such as Supplemental Security Income. They also may require accessibly designed housing to accommodate needs related to their specific disabilities. In Atherton,

7.8% of residents have a disability of any kind. While there are not any housing units in the Town that are specifically tailored to the needs of individuals with disabilities, such as supportive housing or assisted living facilities, the data appears to indicate that Town residents with disabilities are housed, typically with family members who are able to provide for their needs.

Seniors (individuals 64 years of age or older) are another segment of the population with special housing needs. As previously mentioned, 22.4% of Atherton’s population, or 1,596 individuals, were seniors in 2019. Currently, there are no senior housing units in Atherton. However, as the population of the Town continues to age, there may be a greater need for more senior housing (i.e. smaller, multifamily units, or accessible units), spurred by a growing trend by many to age-in-place or downsize to remain in their communities.

Additionally, 13% of Atherton households are larger households with five or more people, who likely need larger housing units of three bedrooms or more. Since 0% of the large households in the Town are considered very low-income and 94% of the units in the Town are three or more bedrooms, the high cost of housing in the Town has not prevented a majority of these large families from securing adequate housing.

Finally, 5.4% of households in the Town are female-headed families, which can be of greater risk of housing insecurity, or losing their home. In the Town, 7.8% of female-headed households with children and 0% of female-headed households without children, or a total of 11 households, fall below the Federal poverty line.

Development of deed-restricted affordable units may help to ensure these households are able to remain in the Town.

3.300 ATHERTON FAIR HOUSING ASSESSMENT

3.310 Introduction – What is Fair Housing?
The State of California’s 2018 Assembly Bill (AB 686) requires that all public agencies in the state affirmatively further fair housing (AFFH) beginning January 1, 2019. Public agencies receiving funding from the U.S. Department of Housing and Urban Development (HUD) are also required to demonstrate their commitment to AFFH. The federal obligation stems from the fair housing component of the federal Civil Rights Act mandating federal fund recipients to take “meaningful actions” to address segregation and related barriers to fair housing choice. The Town does not receive HUD funding.

AB 686 requires all public agencies to “administer programs and activities relating to housing and community development in a manner that affirmatively furthers fair housing, and take no action inconsistent with this obligation”9
AB 686 also makes changes to Housing Element Law to incorporate requirements to AFFH as part of the housing element and general plan to include an analysis of fair housing outreach and capacity, integration and segregation, access to opportunity, disparate housing needs, and current fair housing practices.

Affirmatively Furthering Fair Housing
“Affirmatively furthering fair housing” means taking meaningful actions, in addition to combating discrimination, that overcome patterns of segregation and foster inclusive communities free from barriers that restrict access to opportunity based on protected characteristics. Specifically, affirmatively furthering fair housing means taking meaningful actions that, taken together, address significant disparities in housing needs and in access to opportunity, replacing segregated living patterns with truly integrated and balanced living patterns, transforming racially and ethnically concentrated areas of poverty into areas of opportunity, and fostering and maintaining compliance with civil rights and fair housing laws. The duty to affirmatively further fair housing extends to all of a public agency’s activities and programs relating to housing and community development. (Gov. Code, § 8899.50, subd. (a)(1).)”

History of segregation in the region. The United
States’ oldest cities have a history of mandating
segregated living patterns—and Northern
California cities are no exception. ABAG, in its
recent Fair Housing Equity Assessment, attributes
segregation in the Bay Area to historically
discriminatory practices—highlighting redlining
and discriminatory mortgage approvals—as
well as “structural inequities” in society, and
“self-segregation” (i.e., preferences to live near
similar people). The narrative below applies
regionally and is not solely specific to the Town
of Atherton.

Researcher Richard Rothstein’s 2017 book The
Color of Law: A Forgotten History of How Our
Government Segregated America chronicles
how the public sector contributed to the
segregation that exists today. Rothstein
highlights several significant developments in
the Bay Area region that played a large role in where the region’s non-White residents settled.

Pre-civil rights San Mateo County faced resistance to racial integration, yet it was reportedly less direct than in some Northern California communities, taking the form of “blockbusting” and “steering” or intervention by public officials. These local discriminatory practices were exacerbated by actions of the Federal Housing Administration which excluded low-income neighborhoods, where the majority of people of color lived, from its mortgage loan program.

According to the San Mateo County Historical Association. San Mateo County’s early African Americans worked in a variety of industries, from logging, to agriculture, to restaurants and entertainment. Expansion of jobs, particularly related to shipbuilding during and after World War II attracted many new residents to the Peninsula, including the first sizable migration of African Americans. Enforcement of racial covenants after the war forced the migration of the county’s African Americans into neighborhoods where they were allowed to occupy housing. Typically, this housing was segregated into less desirable areas, such as next to highways, and concentrated in public housing and urban renewal developments.

This history of segregation in
the region is important not
only to understand how
residential settlement
patterns came about—but,
more importantly, to explain
differences in housing
opportunity among residents
today. In sum, not all
residents had the ability to
build housing wealth or
achieve economic
opportunity. This historically
unequal playing field in part
determines why residents
have different housing needs
today.

January 2023
The private sector contributed to segregation through activities that discouraged (blockbusting) or prohibited (restrictive covenants) integrated neighborhoods. The segregationary effect of blockbusting activities in the County is most well-documented in East Palo Alto. In 1954, after a white family in East Palo Alto sold their home to an African American family, the then-president of the California Real Estate Association set up an office in East Palo Alto to scare white families into selling their homes (“for fear of declining property values”) to agents and speculators. These agents then sold these homes at over-inflated prices to African American buyers, some of whom had trouble making their payments. Within six years, East Palo Alto—initially established with “whites only” neighborhoods—became 82% African American. The FHA prevented reintegration by refusing to insure mortgages held by white buyers residing in East Palo Alto.

Throughout the county, neighborhood associations and city leaders attempted to thwart integration of communities. Although some neighborhood residents supported integration, most did not, and it was not unusual for neighborhood associations to require acceptance of all new buyers. Builders with intentions to develop for all types of buyers (regardless of race) found that their development sites were rezoned by planning councils, required very large minimum lot sizes, and\or were denied public infrastructure to support their developments or charged prohibitively high amounts for infrastructure.

The timeline of major federal acts and court decisions related to fair housing choice and zoning and land use appears on the following page.

As shown in the timeline, exclusive zoning practices were common in the early 1900s.

Courts struck down only the most discriminatory and allowed those that would be considered today to have a “disparate impact” on classes protected by the Fair Housing Act. For example, the 1926 case Village of Euclid v. Amber Realty Co. (272 U.S. 365) supported the segregation of residential, business, and industrial uses, justifying separation by characterizing apartment buildings as “mere parasite(s)” with the potential to “utterly destroy” the character and desirability of neighborhoods. At that time, multifamily apartments were the only realistic housing options for people of color, including immigrants.

The Federal Fair Housing Act was not enacted until nearly 60 years after the first racial zoning ordinances appeared in U.S. cities. This coincided with a shift away from federal control over low-income housing toward locally-tailored approaches (block grants) and market-oriented choice (Section 8 subsidies)—the latter of which is only effective when adequate affordable rental units are available.

3.321 Primary Findings
This section summarizes the primary findings from the Fair Housing Assessment for Atherton including the following sections: fair housing enforcement and outreach capacity, integration and segregation, access to opportunity, disparate housing needs, and contributing factors and the town’s fair housing action plan.

From 2017 to 2021, 57 fair housing complaints in San Mateo County were filed with the U.S. Department of Housing and Urban Development (HUD)—there were no complaints identified for Atherton. Compared to nearby Redwood City and Menlo Park, Atherton does not appear to have any housing stock currently used by renters with housing vouchers. The Town does not have an inventory of income assisted rental units and to our knowledge, no one has requested the use of vouchers.

Atherton stands out for the income level of its residents and high ownership rates.

Racial and ethnic minorities living in Atherton are wealthier compared to the county. However, in general:

Households of other or multiple races experience higher rates of cost burden—56% are extremely cost burdened, compared to 16% in Atherton overall (Figure IV-11). Lower income households are also more likely to experience housing cost burden. One out of seven households with income below 80% AMI are severely cost burdened (Figure IV-10).

Racial and ethnic minorities are more likely than non-Hispanic White households to experience overcrowding. Other races (21% of households), and Hispanic households (19%), experience the highest rates of overcrowding (Figure IV-17).

Disparities by race and ethnicity are prevalent for home mortgage applications, particularly in denial rates. Hispanic (60% denial rate) and Asian/API (29%) have the highest denial rates for mortgage loan applications in 2018 and 2019, compared to non-Hispanic White households (18%) (Figure IV-33).

Population growth in Atherton since 2010 has been slower than the County’s and the town has not reached the population level it had prior to the late 1900’s (Figure IV-1). Despite the low population growth, home values accelerated since 2014 (Figure IV-5). Atherton is part of Silicon Valley and home prices have been driven by the regional economy that has generated significant value. Atherton is one of

Town of Atherton 2023-2031 Housing Element – DRAFT 18
January 2023
the region's most expensive communities. Though it is separately incorporated, its economy and home prices are largely due to regional growth and demand.

However, growth in home prices has not translated to more building activity.

According to the ABAG Housing Data Workbook, the majority of the housing inventory in Atherton was constructed from 1940 to 1959, with 1,087 units built between 1940 to 1959 compared to 180 units built in 2010 or later (Figure IV-3).

However, actual Town building permit records reflect that from 2010 forward more than 320 new single-family home building permits were issued.

Atherton has relatively the same share of residents with a disability compared to the county (Figure III-17). In general, residents living with a disability are more likely to be unemployed and an aging population is putting a strain on paratransit access countywide.

Regionally, unemployment is disproportionately high among residents living with a disability at 11% compared to 5% for residents without a disability in Atherton—particularly when compared to the county (Figure III-20).

Atherton is served by the Menlo Park City, Redwood City, and Las Lomitas Elementary School Districts. The Town is split into thirds amongst these districts.

Countywide 27% of Hispanic students met or exceeded mathematics testing standards and 40% met or exceeded English testing standards. Hispanic students in Menlo Park City Elementary, Las Lomitas Elementary, and Redwood City Elementary, which includes Atherton’s Adelante Selby Spanish Immersion School, performed better compared to the county (55%, 44%, and 34% respectively in mathematics and 62%, 65%, and 43% in English).

Overall, 29% of public-school students in San Mateo County qualify for reduced lunch. This was substantially higher in Redwood City Elementary School District, where 56% of students qualify for reduced lunch which includes Atherton’s Adelante Selby Spanish Immersion School. County-wide, 20% of public-school students are English learners. Again, this rate is higher at Redwood City Elementary, where 38% of students are English learners. In contrast, the share of students who qualify for reduced lunch, are experiencing homelessness, or are English learners is lower and significantly lower at Menlo Park City Elementary and Las Lomitas Elementary, respectively, than the countywide share (Disparate Access to Educational Opportunities Appendix).

January 2023
At the high school level, Sequoia Union district has the highest dropout rate in the County (10%), with dropout rates among Pacific Islander (20%), Hispanic (16%), and Black (12%) students are being higher than amongst their peers of other races and/or ethnicities (Disparate Access to Educational Opportunities Appendix).

3.330 Fair Housing Enforcement and Outreach Capacity
This section discusses fair housing legal cases and inquiries, fair housing protections and enforcement, and outreach capacity.

Fair housing legal cases and inquiries. California fair housing law extends beyond the protections in the Federal Fair Housing Act (FHA). In addition to the FHA protected classes—race, color, ancestry/national origin, religion, disability, sex, and familial status—California law offers protections for age, sexual orientation, gender identity or expression, genetic information, marital status, military or veteran status, and source of income (including federal housing assistance vouchers).

The California Department of Fair Employment in Housing (DFEH) was established in 1980 and is now the largest civil rights agency in the United States. According to their website, the DFEH’s mission is, “to protect the people of California from unlawful discrimination in employment, housing and public accommodations (businesses) and from hate violence and human trafficking in accordance with the Fair Employment and Housing Act (FEHA), Unruh Civil Rights Act, Disabled Persons Act, and Ralph Civil Rights Act”.10
DFEH receives, evaluates, and investigates fair housing complaints. DFEH plays a particularly significant role in investigating fair housing complaints against protected classes that are not included in federal legislation and therefore not investigated by HUD. DFEH’s website provides detailed instructions for filing a complaint, the complaint process, appealing a decision, and other frequently asked questions.11 Fair housing complaints can also be submitted to HUD for investigation.

Additionally, San Mateo County has a number of local enforcement organizations including Project Sentinel, the Legal Aid Society of San Mateo County, and Community Legal Services in East Palo Alto. These organizations receive funding from the County and participating jurisdictions to support fair housing enforcement and outreach and education in the County.

January 2023
From 2017 to 2021, 57 fair housing complaints in San Mateo County were filed with the U.S. Department of Housing and Urban Development (HUD)—none of the complaints were in Atherton. The data below reflects complaint data submitted for the region.

Countywide, most complaints cited disability status as the bias (56%) followed by race (19%), and familial status (14%). No cause determination was found in 27 complaints followed by successful conciliation or settlement with 22 complaints. Fair housing inquiries in 2020 were submitted primarily from the City of San Mateo, Redwood City, Daly City, and Menlo Park.

Fair housing complaints filed with HUD by San Mateo County residents have been on a declining trend since 2018, when 18 complaints were filed. In 2019, complaints dropped to 5, increased to 11 in 2020, and had reached 6 by mid-2021.

Nationally, the National Fair Housing Alliance (NFHA) reported a “negligible” decrease in the number of complaints filed between 2019 and 2020. The primary bases for complaints nationally were nearly identical to San Mateo County’s: disability (55%) and race (17%). Familial status represented 8% of complaints nationally, whereas this basis comprised 14% of cases in the county.

NFHA identifies three significant trends in 2020 that are relevant for San Mateo County:

First, fair lending cases referred to the Department of Justice from federal banking regulators have been declining, indicating that state and local government entities may want to play a larger role in examining fair lending barriers to homeownership.

Second, NFHA identified a significant increase in the number of complaints of harassment—1,071 complaints in 2020 compared to 761 in 2019.

Finally, NFHA found that 73% of all fair housing complaints in 2020 were processed by private fair housing organizations, rather than state, local, and federal government agencies—reinforcing the need for local, active fair housing organizations and increased funding for such organizations.12 There were no complaints filed against the Town. Residents in Atherton are either not confronted by housing discrimination, or, if they are, have the financial power to overcome it without filing a complaint. There are affordable housing opportunities at Menlo College for students, staff, faculty, and their families; as well as accessory 12 https://nationalfairhousing.org/2021/07/29/annual-fair-housing-report-shows-increase-inhousing-harassment/

January 2023
dwelling units throughout Town rented at affordable rates. There too, there have not been any housing complaints filed.

In preparing this AFFH, the San Mateo County jurisdictions participating in 21 Elements participated in a discussion with the local fair housing organizations Legal Aid of San Mateo County and Project Sentinel to learn about fair housing trends and concerns, as well as to discuss best practices in AFFH. Following this discussion, the consultant team contacted local fair housing organizations to obtain local data on fair housing complaints and lawsuits beyond what was available in HCD and HUD datasets.

Consultants also obtained and analyzed data from HUD. These datasets were compared for duplicate cases and analyzed and appear in the graphics and tables in this section.

Outreach and capacity. The Town of Atherton has posted its Draft Housing Element for 2023-2031 and advertised to residents an ADU survey, held multiple special meetings and study sessions with the City Council, and held community forums in January to gain input on the final Housing Element. The outreach was conducted via direct mailers to each property owner, use of social media, e-blasts to the Town’s registered email list and emails to housing organizations requesting notification.

Atherton has and will improve the accessibility of fair housing information on its website and resources for residents experiencing housing discrimination. Information on housing resources has already been expanded on the town’s website as well as information or resources for residents experiencing discrimination in housing or the Fair Housing Act. This includes providing contact information for local fair housing organizations, legal assistance, and general information about the Fair Housing Act and discrimination.

The greatest barrier to construction of affordable housing in Atherton is the high cost of land. Property values in Atherton greatly outpace average land cost in other jurisdictions in San Mateo County. The current average cost of a developed acre is $7-$8 million. The Town believes that the high cost of land deters development opportunities for large-scale affordable housing projects. The Town believes that a distributed approach through the use of an ADU and JADU development and rental program mitigates the high cost of land and will ultimately be more successful. The Town has also identified several properties for rezoning to permit multifamily housing.

The graph below shows the radical difference in home values in Atherton that reflect the high cost of land as compared to other jurisdictions in San Mateo County and throughout the Bay Area.

According to the California Department of Housing and Community Development AFFH Data Viewer (HCD data viewer), Atherton does not have public housing buildings. Atherton also does not have a significant share of households using housing vouchers.

Compared to nearby Redwood City and Menlo Park, to the Town’s knowledge, the Town does not have housing stock being utilized by renters with housing vouchers. The lack of presence of housing voucher users could indicate limited or no rental supply to house these residents.

Town of Atherton 2023-2031 Housing Element – DRAFT 25
January 2023
Bay Area policies are interconnected; Atherton’s land use policies that limit the parcel size and restrict multifamily development contribute to housing shortages in other areas of the county. Due to the high cost of housing, town employees and service workers are forced to other areas in search of affordable housing that is not found in the town in which they work. However, the Town does support the expansion of multifamily housing for students, staff and faculty at its local school sites that opens up affordable housing found in other communities by housing these individuals locally.

The figure above shows Atherton lacks renter-occupied housing compared to San Mateo County and the Bay Area. 40% of San Mateo County households are renters compared to only 7% in Atherton. This suggests that workers who cannot afford Atherton must rent elsewhere in the county, given the very limited numbers of rental units in Atherton. There are only 150 renter households in Atherton compared to 2,065 owner-occupied households. These statistics do not include multifamily rental opportunities at school sites. Both numbers have stayed relatively stagnant since 2000.

Renters in Atherton are young: 74% of those aged 15-24 and 88% of those aged 25-34 are renters. Unless they benefit from familial wealth, these renters must leave the town to purchase homes. Data is from ACS 5-year data (2015-2019).

According to ACS data, there are no multi-family homes, boats, RVs, vans or other types of housing in Atherton. 93% (2,021) of detached single-family homes are owneroccupied and 7% (150) are renter-occupied—providing the only rental stock in

Town of Atherton 2023-2031 Housing Element – DRAFT 26
January 2023
Atherton. All attached single-family homes (38) and mobile homes (6) are owneroccupied. Attached single-family homes have grown by only 30 homes and single family detached homes have lost 61 units in the past decade. The California Department of Finance counts six multi family homes with two to four units built in 2020.

Local Data and Knowledge. The demographics seen today are rooted in the region's history. In the 1960s, continued disinvestment and urban renewal in areas surrounding Atherton, such as East Palo Alto, exacerbated housing and education inequality.

Frustrated families in East Palo Alto petitioned for redistricting to address their concerns about education. The lines were drawn and redrawn, and eventually many Black students were bussed to Menlo-Atherton high school. Entrenched housing segregation translated to tension within the school. Black students felt unwelcome and white students felt unsafe in what developed as a microcosm of the exclusionary housing debate formed outside the school walls. The District Board of Trustees representing Menlo-Atherton High responded by limiting the policy to include only students living two miles or more from the school, strategically excluding Black neighborhoods as white students mostly had their own transportation. Protests and fighting ensued.13 Housing and educational boundaries go hand in hand. Over the years, overt tension has abated, but the effects of District policies and land use decision-making can still be seen. The zoning code in Atherton limits parcel size to primarily 1-acre parcels. This land use policy impacts student demographics (1) by limiting the overall number of students and (2) by skewing upward the household income level of those students due to the extremely high land cost. The zoning code in Atherton has almost exclusively permitted 1-acre parcels and single-family developments. The population charts below show how Atherton’s history is reflected in the demographics today. Data is from ACS.

3.340 Integration and Segregation
This section discusses integration and segregation of the population by protected classes including race and ethnicity, disability status, familial status, and income status.

Integration and Segregation
“Integration generally means a condition in which there is not a high concentration of persons of a particular race, color, religion, sex, familial status, national origin, or having a disability or a particular type of disability when compared to a broader geographic area.

Segregation generally means a condition in which there is a high concentration of persons of a particular race, color, religion, sex, familial status, national origin, or having a disability or a type of disability in a particular geographic area when compared to a broader geographic area.”
Race and ethnicity. Atherton is a less diverse community compared to the county. The largest proportion of the population is non-Hispanic White (69% v. 39% countywide), followed by Asian/API (21% v. 30% countywide). Residents of other or multiple races make up 5% of the population, Hispanic residents make up 4% of the population, and

Town of Atherton 2023-2031 Housing Element – DRAFT 28
January 2023
Black or African American residents make up 1%.14 The chart below, informed by ACS 2019 5-year data, shows the differences in racial makeup between Atherton, San Mateo County, and the Bay Area. Note that diversity by age cohort varies—older residents are less diverse with 89% of the population older than 65 years identifying as White compared to 61% of the population for children under the age of 18 years old.

The Dissimilarity Index, or DI, is a common tool that measures segregation in a community. The DI is an index that measures the degree to which two distinct groups are evenly distributed across a geographic area. The DI represents the percentage of a group’s population that would have to move for each area in the county to have the same percentage of that group as the county overall.

DI values range from 0 to 100—where 0 is perfect integration and 100 is complete segregation. Dissimilarity index values between 0 and 39 generally indicate low segregation, values between 40 and 54 generally indicate moderate segregation, and values between 55 and 100 generally indicate a high level of segregation. 14 The share of the population that identifies as American Indian or Alaska Native is less than 1%.

Town of Atherton 2023-2031 Housing Element – DRAFT 29
January 2023
The isolation index is interpreted as the probability that a randomly drawn minority resident shares an area with a member of the same minority, it ranges from 0 to 100 and higher values of isolation tend to indicate higher levels of segregation.

Disability status. The share of the population living with at least one disability is 8% in Atherton, which is the same as in San Mateo County. This has changed little over time, as the population was 7% in 2012. The three most common types of disabilities among those Atherton residents who indicated they were disabled are ambulatory difficulties (4.5%), cognitive difficulties (3.0%) and hearing difficulties (3.0%). No census tracts in the Town with a share of the population living with a disability above 10%. Geographic concentrations of people living with a disability may indicate the area has ample access to services, amenities, and transportation that support this population.

In addition, there are an estimated 18 individuals in Atherton with developmental disabilities, which include Down's Syndrome, autism, epilepsy, cerebral palsy, and mild to severe mental retardation. Of those in Atherton with a developmental disability,

27.8% are children under the age of 18 and 72.2% are adults. The most common living situation for individuals with developmental disabilities in Atherton is the home of a parent, family member or guardian; the second most common is independent or supported living facilities.

Familial Status. Atherton is home to more married-couple families and families with children than the county with 74% households being married-couple families compared to only 55% in the County. The town is home to fewer single-person households (13% v. 22% countywide v. 25% for the Bay Area). This is up from 61.7% of married-couple families in Atherton in 2010. The large, expensive homes in the area may draw prosperous couples in while also making it necessary to have incomes of two people to be able to afford the cost of living. Atherton has a similar share of families with children as both the county and the region (35% v. 33% countywide v. 32% for the Bay Area). It would appear that the greater concentration of large, singlefamily homes in Atherton compared to the region has little impact on the presence of children in a household.

The vast majority of households in Atherton are homeowners (93%). The number of housing units available by number of bedrooms and tenure is consistent with the familial status of the households that live in Atherton.

Household income. The household income distribution by percent of area median income (AMI) in Atherton is much more concentrated at above 100% AMI compared

Town of Atherton 2023-2031 Housing Element – DRAFT 30
January 2023
to the county (79% v. 49% countywide). There are no census tracts in the town with concentrations of poverty rates over 10%.. The Town has fewer extremely low-income and very low-income households, both at 6%, than the County as a whole, at 13% and 11%, respectively.

Throughout the region, the number of low-income renters greatly outpaces the amount of housing available that is affordable for these households. In Atherton, however, the largest proportion of both renters and homeowners fall within the “greater than 100% of AMI” income group. Zoning exclusively for single family home development can drive up the area median income.

3.3550 Racially or ethnically concentrated areas of poverty and affluence Racially Concentrated Area of Poverty or an Ethnically Concentrated Area of Poverty (R/ECAP) and Racially Concentrated Areas of Affluence (RCAAs) represent opposing ends of the segregation spectrum from racially or ethnically segregated areas with high poverty rates to affluent predominantly white neighborhoods. Historically, HUD has paid particular attention to R/ECAPs as a focus of policy and obligations to AFFH.

Recent research out of the University of Minnesota Humphrey School of Public Affairs

Town of Atherton 2023-2031 Housing Element – DRAFT 32
January 2023
argues for the inclusion of RCAAs to acknowledge current and past policies that created and perpetuate these areas of high opportunity and exclusion.15 It is important to note that R/ECAPs and RCAAs are not areas of focus because of racial and ethnic concentrations alone. This study recognizes that racial and ethnic clusters can be a part of fair housing choice if they occur in a non-discriminatory market. Rather, R/ECAPs identify areas where residents may have historically faced discrimination and continue to be challenged by limited economic opportunity, and conversely, RCAAs are meant to identify areas of particular advantage and exclusion.

R/ECAPs
HCD and HUD’s definition of a Racially/Ethnically Concentrated Area of Poverty is:

A census tract that has a non-White population of 50 percent or more (majorityminority) or, for non-urban areas, 20 percent, AND a poverty rate of 40 percent or more; OR
A census tract that has a non-white population of 50 percent or more (majorityminority) AND the poverty rate is three times the average tract poverty rate for the County, whichever is lower.

Source: California Department of Housing and Community Development Guidance, 2021.

For this study, the poverty threshold used was three times the average tract poverty rate for the County—or 19.1%. In addition to R/ECAPs that meet the HUD threshold, this study includes edge or emerging R/ECAPs which hit two thirds of the HUD defined threshold for poverty—emerging R/ECAPs in San Mateo County have 2 times the average tract poverty rate for the county (12.8%).

In 2010 there were three census tracts that qualify as R/ECAPs (19.4% poverty rate) in the county and 11 that qualify as edge R/ECAPs (13% poverty rate). None of the R/ECAPs were located in Atherton in 2010.

In 2019 there are two census tracts that qualify as R/ECAPs (19.1% poverty rate) in the county and 14 that qualify as edge R/ECAPs (12.8% poverty rate). None of the 2019 R/ECAPs or edge R/ECAPs are located in Atherton. Below is the map for R/ECAPS in 2010.

There are two R/ECAPs bordering Atherton in the Redwood City area and several more edge R/ECAPs. The cluster of R/ECAPs on the border of Atherton is significant because it shows that 1) minority census tracts tend not to access resources west of Redwood City, including Atherton; and 2) there are stronger minority communities that choose to live outside of the affluent, neighborhoods in Atherton. Both of these options inform each other.

Town of Atherton 2023-2031 Housing Element – DRAFT 34
January 2023
In 2019, there remains a cluster of R/ECAPs and edge R/ECAPS on the border of Atherton. The only change in the maps regionally is the expansion of the East Palo Alto/ Menlo Park area as an edge R/ECAP.

RCAAs. HCD’s definition of a Racially Concentrated Area of Affluence is:

Town of Atherton 2023-2031 Housing Element – DRAFT 36
January 2023
A census tract that has a percentage of total white population that is 1.25 times higher than the average percentage of total white population in the given COG region, and a median income that was 2 times higher than the COG AMI.

Atherton is considered an RCAA (based on 2019 data) because its total white population is 67% while that of the Association of Bay Area Governments (ABAG) is 40%. The map below shows Atherton’s proximity to other RCAAs. Atherton is largely surrounded by communities that are also RCAAs. These include portions of Menlo Park, Woodside, Portola Valley, Palo Alto, and Redwood City. As one travels West on El Camino Real towards Redwood City, there are fewer RCAAs. Although maps are not available through time, analysis shows that the white population has remained the majority demographic throughout Atherton’s history. Atherton has consistently had high home prices compared to San Mateo County and the Bay Area, suggesting that high income people are drawn to the area and are willing to pay a high price for large homes in the residential town. The Stanford area has more racial and income diversity from its student body and staff. The Palo Alto area is still expensive, and many employees of the University likely bypass Atherton and Menlo Park for cheaper housing in Sunnyvale and Redwood City.

Although poverty rates within Atherton are very low, there are still minor disparities by race. For example, 5.3% of Asian and Asian Pacific Islanders are in poverty compared to 3.5% of white households. While the percentage is zero, Black, American Indian and Alaska Native populations may also face poverty in Atherton, but this should be interpreted with caution as the sample is far too small to draw conclusions. This chart shows that, although the area is considered a RCAA, within Atherton’s small Black Indigenous and People of Color (BIPOC) population there are variations of experience.

3.360 Access to Opportunity
This section discusses disparities in access to opportunity among protected classes including access to quality education, employment, transportation, and environment.

Access to Opportunity
“Access to opportunity is a concept to approximate place-based characteristics linked to critical life outcomes. Access to opportunity oftentimes means both improving the quality of life for residents of low-income communities, as well as supporting mobility and access to ‘high resource’ neighborhoods16. This encompasses education, employment, economic development, safe and decent housing, low rates of violent crime, transportation, and other opportunities, including recreation, food and healthy 16 Neighborhoods with the greatest access to public parks, transit, schools, grocery stores, and health facilities.

environment (air, water, safe neighborhood, safety from environmental hazards, social services, and cultural institutions).”
Source: California Department of Housing and Community Development Guidance, 2021, page 34.

The California Tax Credit Allocation Committee (TCAC) in collaboration with HCD developed a series of opportunity maps that help to identify areas of the community with good or poor access to opportunity for residents. These maps were developed to align funding allocations with the goal of improving outcomes for low-income residents—particularly children.

The opportunity maps highlight areas of highest resource, high resource, moderate resource, moderate resource (rapidly changing), low resource and high segregation and poverty. TCAC provides opportunity maps for access to opportunity in quality education, employment, transportation, and environment. Opportunity scores are presented on a scale from zero to one and the higher the number, the more positive the outcomes.

Education. TCAC’s education score is based on math proficiency, reading proficiency, high school graduation rates, and the student poverty rate. According to TCAC’s educational opportunity map, census tracts in Atherton score between 0.25 and

0.75—opportunity scores are presented on a scale from zero to one and the higher the number, the more positive the outcomes. The census tract scoring between 0.25 and

0.50 is located west of El Camino Real and the census tract to the east scores between

0.50 and 0.75.

Patterns within San Mateo County reveal that over the last decade, schools have become increasingly more diverse, with Hispanic students making up 38% of enrollments. Ravenswood and Redwood City, to the West and Northeast of Atherton respectively, have the highest number of Hispanic students in the County at 84% and 70%. In Redwood City Elementary, which includes Adelante Selby Spanish Immersion School in Atherton, more than one-third of students are English learners. Ravenswood serves the census tract that scored between 0.25 and 0.50. Therefore, the significant number of English learner students could be skewing down the educational outcomes in that census tract compared to schools with more proficient English speakers An astounding 30% of students at Ravenswood Elementary are experiencing homelessness compared to the county-rate of 2%. Without a stable place to complete schoolwork and, most importantly, feel safe and secure, students are unable to reach their full potential and thus have lower education scores. There are limited affordable

January 2023
housing options in Atherton and other jurisdictions surrounding Ravenswood for families to access once they are displaced.

Atherton is served by the Menlo Park City, Redwood City, and Las Lomitas Elementary School Districts; and the Sequoia Union Unified High School District.

Menlo Park City Elementary experienced an increase in enrollment of 6% from 2010 to 2020, while enrollment in Redwood City Elementary and Las Lomitas Elementary decreased 11% and 16% respectively. This represents a much larger decrease than the one percent decrease experienced in the county.

Enrollment in Sequoia Union Unified High School District increased by 18% from 2010 to 2020. Enrollment at Menlo Atherton High School is approximately 2,400 students, with 5% of those students residing in Atherton.

Enrollment composition by race and ethnicity varies by district. Menlo Park City Elementary and Las Lomitas Elementary have a higher share of White students than San Mateo County (55%, and 53% respectively, v. 26%). Redwood City Elementary has a much higher share of Hispanic students than San Mateo County (70% v. 38%). The enrollment composition in Sequoia Union High School District is similar to the countywide distribution.

Atherton has received an average of 18 short-term enrollments of migrant student workers per year according to California Department of Education data. This is significantly fewer than the county level, which sees an average of 416 per year.

Overall, 29% of public-school students in San Mateo County qualify for reduced lunch.

This number was substantially higher in Redwood City Elementary School District (which includes Atherton’s Adelante Selby Spanish Immersion School), where 56% of students qualify for reduced lunch. County-wide, 20% of public-school students are English learners. Again, this rate is higher at Redwood City Elementary, where 38% of students are English learners.

In contrast, the share of students who qualify for reduced lunch, are experiencing homelessness, or are English learners is lower in Menlo Park City Elementary and is significantly lower in Las Lomitas Elementary than the countywide share.

Countywide 27% of Hispanic students met or exceeded mathematics testing standards and 40% met or exceeded English testing standards. Hispanic students in Menlo Park City Elementary, Las Lomitas Elementary, and Redwood City Elementary, which includes Atherton’s Adelante Selby Spanish Immersion School, performed better

Town of Atherton 2023-2031 Housing Element – DRAFT 41
January 2023
compared to the county (55%, 44%, and 34% respectively in mathematics and 62%, 65%, and 43% in English).

Many high schoolers in the county met admission standards for a University of California (UC) or California State University (CSU) school. Of the high school districts in San Mateo County, Sequoia Union had the highest rate of graduates who met such admission standards at 69% followed by San Mateo Union High with 68%. Pacific Islander, Hispanic, and Black students in the Sequoia Union district were less likely than their peers of other races and ethnicities to meet the admission standards with rates of 38%, 55%, and 50%, respectively.

Despite the high share of students meeting college admission standards, Sequoia Union has the second to lowest college going rate in the County, at 70%. The highest rate was 77% in San Mateo Union High.

In addition, Sequoia Union district has the highest dropout rate in the County (10%) and dropout rates among Pacific Islander (20%), Hispanic (16%), and Black (12%) students are much higher. Students with disabilities and those learning English dropped out at the highest rate at 24% and 27%, respectively. This is a sign that the district does not offer adequate support for students facing barriers because of their race, language skill, and disability. However, there are promising increases in diversity of school staff that serve as an advantage to a diverse student body.

Another possible reason can be traced to chronic absenteeism, which means students miss more than 10% of school days. 17% of students in the Sequoia Union High School District struggle with chronic absenteeism, which drastically lowers test scores and social engagement with peers and mentors. Black and Hispanic students were more likely to be chronically absent. Schools with more homeless students also saw more chronic absenteeism, illuminating a connection between school performance and stable housing.

Menlo College has a student population of more than 825. Demographics of the College are 29% White, 6% Black, 22% Hispanic, 10% Asian, 1% American Indian/Alaskan, 2% Hawaiian/Pacific Islander, 8% Two or More races, 14% International and 9% Race Unknown.

Employment. According to ACS data, the top three industries by number of jobs in Atherton include professional and managerial services, health and educational services, and arts and recreation services. In the terms of job holders, the top industries are professional and managerial services, and health and educational services. The chart below shows employment by industry and region.

Town of Atherton 2023-2031 Housing Element – DRAFT 42
January 2023
Atherton has a lower job to household ratio at 1.14 when compared to the county at

1.59. The town has a slightly higher unemployment rate than the county, but saw a sharp incline in the unemployment rate in 2020 that has yet to return to pre pandemic levels.

TCAC’s economic opportunity score is comprised of poverty, adult educational attainment, employment, job proximity, and median home value. The entire town area scores more than 0.75 for economic opportunity—highest economic outcome.

HUD’s job proximity index shows the eastern part of the town in relatively close proximity to jobs (score between 60 to 80) while the western part scores between 40 and 60— on a scale from zero to 100 where 100 is the closest proximity to jobs.

There are several barriers to high paying jobs for protected classes, most of which can be traced back to educational opportunities and outcomes. As highlighted in the previous education section, Black, Hispanic, and English language learners have the highest school absenteeism and drop out rate in the school district covering Atherton.

The majority of employment in Atherton is in the financial and professional service sector and the health and educational services sector. Most of these jobs likely require education beyond high school. Because Black and Hispanic students are more likely

Town of Atherton 2023-2031 Housing Element – DRAFT 43
January 2023
to drop out, employment options that will provide adequate pay to financially qualify for housing in Atherton are drastically reduced.

In general, new jobs continue to outpace new homes, and especially new affordable homes, in the county. Since 2010, the county has added 100,000 jobs but only 10,000 new homes. Jobs are expected to increase 22 percent between 2020 and 2050. So while residents in the county may technically have more employment opportunities, the lack of affordable housing near these jobs will continue to act as a barrier to accessing these employment opportunities
Transportation. This section provides a summary of the transportation system that serves Atherton and the broader region including emerging trends and data relevant to transportation access in the town. The San Mateo County Transit District acts as the administrative body for transit and transportation programs in the county including SamTrans and the Caltrain commuter rail. SamTrans provides bus services in San Mateo County, including Redi-Wheels paratransit service.

In 2018, the Metropolitan Transportation Commission (MTC), which covers the entire Bay Area, adopted a coordinated public transit and human services transportation plan. While developing the coordinated plan, the MTC conducted extensive community outreach about transportation within the area. That plan—which was developed by assessing the effectiveness of how well seniors, persons with disabilities, veterans, and people with low incomes are served—was reviewed to determine gaps in services in San Mateo and the county overall. Below is a summary of comments relevant to San Mateo County. There were no comments specific to Atherton. “San Mateo’s PCC and County Health System, as well as the Peninsula Family Service Agency provided feedback. The most common themes expressed had to do with pedestrian and bicycle needs at specific locations throughout the county, though some covered more general comments such as parked cars blocking sidewalk right-of-way and a desire for bike lanes to accommodate motorized scooters and wheelchairs. Transportation information, emerging mobility providers, and transit fares were other common themes.

While some comments related to the use of car share, transportation network companies (TNCs), or autonomous vehicles as potential solutions, other

Town of Atherton 2023-2031 Housing Element – DRAFT 44
January 2023
comments called for the increased accessibility and affordability of these services in the meantime.”17
A partnership between the World Institute on Disability and the MTC created the research and community engagement project TRACS (Transportation Resilience, Accessibility & Climate Sustainability). The project’s overall goal is to, “stimulate connection and communication between the community of seniors and people with disabilities together with the transportation system– the agencies in the region local to the San Francisco Bay, served by MTC.”18
As part of the TRACS outreach process, respondents were asked to share their compliments or good experiences with MTC transit. One respondent who had used multiple services said, “it is my sense that SamTrans is the best Bay Area transit provider in terms of overall disability accommodation.”
The San Mateo County Transit District updated their Mobility Plan for Older Adults and People with Disabilities in 2018. According to the district, the county’s senior population is expected to grow more than 70% over the next 20 years and the district is experiencing unprecedented increases in paratransit ridership. The plan is targeted at developing effective mobility programs for residents with disabilities and older adults including viable alternatives to paratransit, partnerships, and leveraging funding sources.19
MTC also launched Clipper START—an 18-month pilot project— in 2020 which provides fare discounts on single transit rides for riders whose household income is no more than double the federal poverty level.20 Homeowners in the County are more likely to report that they cannot access public transit easily or safely. In 2020, Caltrain voted to close Atherton’s station due to low ridership. There were some residents that thought this would be harmful to those who do not have access to a car or cannot drive, such as the elderly and disabled community; however, there were alternative resources identified such as the nearby Menlo Park Train Station and associated bus lines on El Camino Real and Middlefield Road.21

Environment. TCAC’s opportunity areas environmental scores are based on the CalEnviroScreen 3.0 indicators, which identify areas disproportionately vulnerable to pollution sources such as ozone, PM2.5, diesel PM, pesticides, toxic release, traffic, cleanup sites, groundwater threats, hazardous waste, impaired water bodies, and solid waste sites.

According to TCAC’s opportunity map, census tracts in Atherton score between 0.25 and 0.75—opportunity scores are presented on a scale from zero to one and the higher the number, the more positive the outcomes. The census tract scoring between

0.25 and 0.50 is located west of El Camino Real and the census tract to the east scores between 0.50 and 0.75. The town scores the highest on the California Healthy Places Index (HPI) developed by the Public Health Alliance of Southern California (PHASC).

The HPI includes 25 community characteristics in eight categories including economic, social, education, transportation, neighborhood, housing, clean environment, and healthcare.22
Disparities in access to opportunity. Racial and ethnic minorities are more likely to live in moderate resource areas compared to non-Hispanic White residents. The chart below details the percentage of households by race living in resource areas. Note that there are no households in Atherton living in a low resource area. 71% of Hispanic households live in moderate resource areas compared with 29% in high resource areas. Similarly, 77% of Black households live in moderate resource areas and 23% live in high resource areas. Non-Hispanic, multiple race households have the highest population in high resource areas, however this population is relatively small with 323 households compared with 4,966 white households. Racial and ethnic minorities living in Atherton are wealthier compared to the county and Atherton is home to a disproportionately small share of residents with limited English proficiency (1% compared to 7% countywide).

TCAC’s composite opportunity score for Atherton shows census tracts west of El Camino Real fall within moderate resource areas while the rest is within high resource areas.

The Social Vulnerability Index (SVI) provided by the CDC—ranks census tracts based on their ability to respond to a disaster—includes four themes of socioeconomic status, household composition, race or ethnicity, and housing and transportation. The index shows Atherton as a low vulnerability area.

Atherton does not have any disadvantaged communities as defined under SB 535, “disadvantaged communities are defined as the top 25% scoring areas from CalEnviroScreen along with other areas with high amounts of pollution and low populations.”23
Disparities specific to the population living with a disability. Eight percent of the population in Atherton are living with at least one disability, the same share as in the 23 https://oehha.ca.gov/calenviroscreen/sb535

county. The most common disabilities in the town are ambulatory (4.5%), cognitive (3.1%), and hearing (3.0%).

Disability
“Disability types include hearing difficulty, vision difficulty, cognitive difficulty, ambulatory difficulty, self-care difficulty, and independent living difficulty.” Source: California Department of Housing and Community Development Guidance, 2021, page 36.

For the population 65 and over the share of the population with an ambulatory or independent living difficulty increases. As mentioned above under access to transportation, San Mateo County is rapidly aging, therefore this population with a disability is likely to increase.

Unemployment is disproportionately high among residents living with a disability at 11% compared to 5% for residents without a disability in Atherton—particularly when compared to the county. High unemployment rates among this population points to a need for increased services and resources to connect this population with employment opportunities.

3.360 Disparate Housing Needs
This section discusses disparate housing needs for protected classes including cost burden and severe cost burden, overcrowding, substandard housing conditions, homelessness, displacement, and other considerations.

Disproportionate Housing Needs
“Disproportionate housing needs generally refers to a condition in which there are significant disparities in the proportion of members of a protected class experiencing a category of housing need when compared to the proportion of members of any other relevant groups, or the total population experiencing that category of housing need in the applicable geographic area. For purposes of this definition, categories of housing need are based on such factors as cost burden and severe cost burden, overcrowding, homelessness, and substandard housing conditions.”

Housing needs. Population growth in Atherton has historically been driven by economic cycles. The town experienced a sharp loss in population between 1999 and 2000 and again between 2009 and 2010. Since 2010 population growth has been slower than the County’s and the town has not reached the population level it had prior to the 2008-09 financial crisis. However, the town does not appear to have experienced a sharp population decrease in 2020 with the COVID-19 pandemic.

Since 2015, the housing construction to accommodate growth has largely been priced for above moderate-income households with 78 units permitted for above moderate-income households compared to 35 for very low-income households, 15 for low-income households, and 3 for moderate income households. The Housing Needs Data Report for Atherton indicates new construction is slower than the rest of the Bay Area. 24One example of a group who has found workforce housing hard to come by are the employees of the Atherton Police Department. In 2018, employees advised the City Council that they faced long commutes on top of twelve-hour shifts and had little time to sleep. The commute was necessary because there are limited affordable options in the region for their families. In the past, the town had used a town-owned property in a deed-restricted park as a place for police to sleep. This solution was not sustainable for the town or police officers, who wanted to spend more time with their families instead of commuting.25 This makes recruitment and retention difficult.

The variety of housing types available in the town in 2020 are predominantly single family (98%). Six multi-family homes were added in 2020. Single family detached saw a decline in units and single family attached saw a small incline. Due to its land use 24 Housing Needs Data Report: Atherton, ABAG/MTC Staff and Baird + Driskell Community Planning, 2021.

zoning and high cost of land, Atherton has developed far fewer multifamily units than the region. 26
According to the ABAG Housing Data Workbook, the majority of the housing inventory in Atherton was constructed from 1940 to 1959, with 1,087 units built between 1940 to 1959 compared to 180 units built in 2010 or later (Figure IV-3). However, actual Town building permit records reflect that from 2010 forward more than 320 new single-family home building permits were issued. Compared to San Mateo County, the Town’s owner-occupied housing market has a greater share of units priced above $2 million.

Ninety percent (90%) of units in Atherton fall within this price range compared to 19% in the county. According to the Zillow home value index, home prices have experienced exponential growth in the town and the county. The town is an outlier, with the Zillow home value index at $6.6 million for Atherton compared to the county’s $1.4 million.

Given the small share of renters in the town, rental price trends are less accurate than the County’s, but appear to have experienced appreciation since 2014. Compared to the county, Atherton has more luxury rental units—67% of units rent for more than $3,000 in the town compared to 22% in the county. A point-in-time Google search found no home for rent under $5,000 per month. Workers would need higher incomes 26 Housing Needs Data Report: Atherton, ABAG/MTC Staff and Baird + Driskell Community Planning, 2021.

to qualify for rentals available in Atherton–and are thus inclined to seek out homeownership or lower cost rental opportunities in other communities. However, the Town is in the process of implementing a robust and inclusive ADU program that will facilitate, support, and encourage the development and rental of accessory dwelling units at affordable rates via a HIP Housing Program.

Resident survey data provide evidence of more rental inventory, reporting that owners are renting ADUs to senior family members, students, school faculty, and local service workers at significantly reduced or below market rental prices. Many of these rental opportunities are not marketed in the traditional way using Zillow, Craigslist or other platforms. Rather, because Atherton is a small community, property owners will reach out directly to those in need of such housing solutions or offer housing through a local school’s housing referral program.

Cost burden and severe cost burden. As expected, a low share of households in Atherton are cost burdened—spending more than 30% of their gross income on housing costs— compared to the county (28% v. 37% in the county).

Lower income households are more likely to experience housing cost burden. One out of seven households with income below 80% AMI are severely cost burdened— spending more than 50% of their gross income on housing costs. Cost burdened households have less money to spend on other essentials like groceries, transportation, education, healthcare, and childcare. Extremely cost burdened households are considered at risk for homelessness. Cost burden suggests that wages have not kept up with housing costs in the area.

When cost burden is broken down by Area Median Income (AMI), there are stark differences. The chart below indicates these disparities. Although those with greater than 100% AMI likely spend the most on housing, their incomes can meet these costs. 80% of those in this group spend 0-30% of their income on housing. In contrast, 88% of those earning 0-30% AMI spend over 50% of their income on housing costs.

As mentioned previously, racial and ethnic minorities living in Atherton are wealthier compared to the county. Asian/API and Hispanic households are less likely to be cost burdened than non-Hispanic white households. Households of other or multiple races experience higher rates of cost burden—56% are extremely cost burdened, compared to 16% in the town overall.

There are also differences by tenure. In San Mateo County, 29.6% of homeowners pay more than 35% of their income towards housing and 42.8% of renters pay more than 35% of their income towards housing costs. This is higher than in Atherton, likely because there are more people over 100% AMI. In Atherton, 29% of owner-occupiers pay more than 30% of income towards housing. Statistics on renter income to housing costs are difficult to calculate because of the low number of renters in Atherton, thus 51% of renter cost has not been calculated in ACS data. From what exists, 65% of renteroccupied households pay more than 30% of income on housing costs and 11% pay 30-50% of income on rent.

The map below shows cost burden by census tract. Discrepancies in the percentage of Atherton renters paying more than 30% of their income for rent may be attributed, as has been noted, to the difficulty of calculating these figures based on the low number of renters in Atherton. ACS 5-year 2019 data shows 20-40% of renters in Atherton are paying more than 30% of their income on rent. Atherton is largely surrounded by cost burdened communities. 60-80% of renters are cost burdened in the

East Palo Alto and Redwood City area. It could be that there are more renters in these adjacent communities because Atherton offers few renter-occupied units. Thus residents of San Mateo County who cannot yet afford a house are forced to pay a high cost of housing as renters in areas outside of Atherton.

January 2023

Town of Atherton 2023-2031 Housing Element – DRAFT 55
January 2023
Cost burden for homeowners is more significant in Atherton. This is not surprising given that there are more owner-occupied single-family homes in the town and therefore there is better data on owners than renters. At least 20% of homeowners in Atherton spend more than 30% of their income on housing costs. Southwest Atherton, which notably had fewer cost burdened renters than other areas of the town, has the town’s highest percentage of homeowners who are cost burdened in the town at 40-60%.

Again, Atherton is surrounded by communities where over 20% of homeowners are cost burdened, suggesting that homeownership is still unaffordable to those even with relatively high incomes.

Overcrowding. The vast majority of households (99%) in Atherton are not overcrowded—indicated by more than one occupant per room.

Racial and ethnic minorities are more likely than non-Hispanic White households to experience overcrowding. Other races (21% of households), and Hispanic households (19%), experience the highest rates of overcrowding.

In San Mateo County, 6.9% of households have more than one occupant per room.

This is slightly better than the state average of 8.2%.

Overcrowding is often related to the cost of housing with multiple households sharing a unit to make it possible to afford the unit. Below, the map shows where overcrowding in the Bay Area is more common. East Palo Alto and Redwood City have the highest percentage of overcrowding in the region, likely because of their high renter population. Multifamily rental units have less bedrooms than single family homes. There are also higher populations of Hispanic residents in these areas. Hispanic households tend to have larger, multigenerational households, which could account for the higher overcrowding rate.

Town of Atherton 2023-2031 Housing Element – DRAFT 58

Substandard housing. Data on housing conditions are very limited, with the most consistent data available across jurisdictions found in the American Community Survey (ACS)—which captures units in substandard condition as self-reported in Census surveys. According to data estimates, the share of housing units with substandard kitchen and plumbing facilities in Atherton is zero, despite an aging housing stock. This data estimate is further substantiated by direction from the Town’s Code Enforcement Officer. . This could be because all residents live in moderate or high resource areas where renovations are financially feasible and most residents are homeowners who are able to modify their units. San Mateo County also has a low rate of substandard housing; 99.9% of households have complete kitchen and plumbing facilities.

As shown in the map below, residents who do not have complete kitchen or plumbing utilities tend also to live in severely overcrowded conditions, and are severely cost burdened, Atherton has less than 20% of residents in substandard conditions. In East Palo Alto and Southeast Redwood City, however, 40-60% of all households selected at least one of the substandard housing issues. Substandard housing congregates in areas of low income because these residents do not have the financial leverage to improve housing conditions, have landlords who are unwilling to make improvements, or do not ask for improvements or report conditions in fear of retaliatory eviction.

Homelessness. In 2019, 1,512 people were experiencing homelessness in the county, 40% of these individuals were in emergency or transitional shelter while the remaining 60% were unsheltered. The majority of unsheltered people experiencing homelessness were in households without children. The majority of people in transitional housing were in households with children. These disparities may indicate there are more resources available in the County for families experiencing homelessness as compared to for single individuals experiencing homelessness.

People who identify as American Indian or Alaskan Native (6% homeless, less than 1% general population), Black (13%, 2%), White (67%, 51%), and Hispanic (38%, 28%) are overrepresented in the homeless population compared to their share of the general population. The disparities by race can be traced back to discrimination in the housing market and the exclusion of non-white populations from high resource areas. There are few housing options for low-income people in the region. Housing that is available at the market rate likely forces people to spend more than 50% of their income on housing, which puts households at risk for homelessness.

People struggling with chronic substance abuse (112 people), severe mental illness (305), and domestic violence (127) represent a substantial share of the homeless population in 2019. This indicates that there are not enough resources or beds for those experiencing mental illness, substance abuse, and domestic violence in the county.

Displacement. Owner households generally enjoy a greater amount of housing stability whereas renter households are more mobile. Atherton has no inventory of income assisted rental units. In San Mateo County, 417 units are at risk, accounting for 8% of the total assisted housing units in the county.

Displacement Sensitive Communities
“According to the Urban Displacement Project, communities were designated sensitive if they met the following criteria:

They currently have populations vulnerable to displacement in the event of increased redevelopment and drastic shifts in housing cost. Vulnerability is defined as:

Town of Atherton 2023-2031 Housing Element – DRAFT 62
January 2023
Share of very low-income residents is above 20%, 2017
AND
The tract meets two of the following criteria:
− Share of renters is above 40%, 2017
− Share of people of color is above 50%, 2017
− Share of very low-income households (50% AMI or below) that are severely rent burdened households is above the county median, 2017
− They or areas in proximity have been experiencing displacement pressures. Displacement pressure is defined as:
● Percent change in rent above county median for rent
increases, 2012-2017
OR
Difference between tract median rent and median rent for surrounding tracts above median for all tracts in county (rent gap), 2017” Source: https://www.sensitivecommunities.org/.

No census tracts in the town are vulnerable to displacement, however, housing cost burden is a risk for displacement and 88% of residents below 30% AMI pay more than 50% of their income on housing Atherton’s rent’s rental cost is far above regional median rent, suggesting that there is displacement pressure in place. Assuming this number trend applies to the Town, that would mean that of the Town’s 149 extremely low-income households, 131 are overburdened by their housing costs.

The chart below shows median rent in Atherton, San Mateo County, and the Bay Area.

Town of Atherton 2023-2031 Housing Element – DRAFT 63

As discussed in the previous section regarding R/ECAPs, Atherton is near edge R/ECAPs in Redwood City and Menlo Park. This suggests that people who may be displaced from Atherton may migrate to these areas and that people within Redwood City and Menlo Park who are displaced cannot access resources within Atherton.

Displacement can also occur because of natural disasters. Atherton is in San Mateo County, which is on the San Andreas fault and therefore has a high likelihood of severe earthquakes. Houses in California are generally made to withstand earthquakes, but those who spend more than 30% of their income on housing costs likely cannot save enough to repair severe damage. This means those of lower income are more at risk of displacement.

Access to mortgage loans. Disparities by race and ethnicity are prevalent for home mortgage applications, particularly in denial rates. Hispanic (60% denial rate) and Asian/API (29%) have the highest denial rates for mortgage loan applications in 2018 and 2019, compared to non-Hispanic White households (18%). These numbers suggest that traditional routes to homeownership are barriers to non-white households. Credit score, assets, and income disparities between races show in denial rates.

3.370 Site Inventory Analysis
There are no R/ECAPs or edge R/ECAPS located within the Town of Atherton. Edge R/ECAPS within unincorporated San Mateo County have proximity to portions of Atherton along the western edge of Town bounding El Camino Real.

The complete inventory of identified opportunity sites is included as Appendix 5 and expanded up in section 3.410.

3.380 Contributing Factors and Fair Housing Action Plan The factors contributing to fair housing challenges within Atherton is the high cost of land acquisition, zoning primarily for single family homes, and little affordable housing for those with moderate and low income who work in the town, other than ADUs and housing at local school sites. Per an analysis completed in 2022, the average land acquisition cost for a single acre in Atherton is approximately $7-8 million. The affordability of land is a high bar to the creation of affordable housing and the greatest barrier to development. The Town has taken a muti-pronged approach to address affordable housing. The best opportunities for affordable housing include ADUs and multi family units on school sites where the land is already owned by the entity. In addition, the Town has identified several properties for upzoning to permit multifamily housing. Coupled with the new multifamily zoning districts, the Town will adopt an inclusionary ordinance to ensure a portion of the new multifamily housing units are available as affordable housing to lower income households. These steps will address fair housing issues, including segregation.

The Town is continuing to see success in the creation of additional ADU units. The Town estimates that 60% of new rental ADU units will be rented at very low or low-income levels. Based on existing precedent, these units are often used for housing for a senior family member, employees of the homeowner, students, or in other similar circumstances where the renter would otherwise be unable to find similar accommodations locally. Consequently, the ADU occupants do not displace others from low-income housing that is available locally.

ADUs have several other advantages. They can be constructed at significantly lower cost than the cost to build a new multifamily unit. They can be located anywhere within the Town, which means such low-income units are geographically spread throughout Atherton. They are also politically popular and easy to permit.

The Town is implementing several strategies to further utilize ADUs as a tool for providing fair housing opportunities, including:
▪ Expanding community outreach to realize additional ADU development.

Town of Atherton 2023-2031 Housing Element – DRAFT 66
January 2023
▪ Developing assistance programs for JADUs to make alterations easier and more cost effective so that additional units can be developed within the existing building envelope of houses and made available at more affordable rates. ▪ Amending the Zoning code to eliminate the occupancy limitation on other accessory units, such as guest houses and pool houses.
▪ Creating an inventory of existing pool houses and guest houses, and then working with a nonprofit to connect homeowners to prospective renters. ▪ Amending the Zoning code to increase the height limit to allow ADUs to be constructed above garages.
▪ Amending the Zoning code to allow two ADUs to be constructed on parcels that are 2 acres or greater.
▪ Amending the Zoning code to allow multiple ADUs to be rented on a property. ▪ Amending the fee resolution to remove the planning review fees for ADUs. ▪ Adopt an affordable housing impact fee on single family construction. The Town will make available funds from this program to provide very low-income rental assistance for eligible households identified by HIP.

The Town’s complete strategy related to encouraging ADU production and the rental of these units is provided in section 3.812.

Further to provide greater diversity in the housing stock and opportunities for lower income households, the Town has included programs to rezone several properties to allow multi-family housing. These properties have been strategically identified to be near transit and services.

Additionally, the Town will be providing additional fair housing resources and training for property owners, real estate agents, and tenants, per section 3.823 E. This will be provided through a collaboration with other cities and towns, Project Sentinel, or other similar organization. This will provide information on reasonable accommodation and issues related to income and other forms of discrimination. This training could be mandated for multi-family developers, property owners and any resident renting an ADU or similar unit. The Town will also create a webpage to host this information and improve awareness around fair housing training, issues and available programs. The webpage will also provide information on filing fair housing complaints with HCD or HUD.

Lastly, as part of its ADU rental strategy, the Town will implement a program to affirmatively market low-income units to households that are under-represented in the Town in comparison to neighboring jurisdictions and the County. To examine the effectiveness and interest in the ADU strategy, a survey of potential renters in the area, such as employees of homeowners, school and city staff, and elderly individuals is also being pursued.

3.400 HOUSING RESOURCES

3.410 Inventory of Sites Suitable for Residential Development

3.411 Parcel-specific List of Available Sites
This section contains an inventory of specific sites suitable for residential development so that a comparison may be made with Atherton’s new construction need by affordability category with its residential development capacity.

The accompanying table (Appendix 5) identifies lands suitable for residential development in Atherton. The HCD Electronic Housing Element Site Inventory Form has been used. Each site is identified by address and assessor’s parcel number and includes the site acreage and existing land use. Existing zoning falls into the categories listed below. It should be noted that Atherton has only four zoning districts, the three listed below plus a Parks and Open Space District.

R-1A (Residential District) - Limits land uses to single-family detached homes on minimum one-acre size lots.

R-1B (Residential District)-Limits uses to single-family detached homes on minimum size 13,500 square foot (0.31 acre) lots.

PFS (Public Facilities and Schools District) - Limits land uses to public and private schools including affiliated residential uses, town hall, library and other similar public and quasipublic uses without limitation on lot size. This district also permits single-family and multifamily residences pursuant to a master plan.

Multifamily Rezonings
A new multifamily overlay zoning district is proposed to be adopted following Housing Element certification to provide a range of housing opportunities to the community.

The RM 10 Multifamily District permits multifamily residential uses by right with a maximum density of 10 dwelling units per acre. The new multifamily zoning district will allow heights up to 40 feet, adequate setbacks to accommodate the maximum density, parking standards and objective design standards.

The property listed below was prioritized for rezoning because it is located close to services, transit, jobs with adequate access along a public right-of–way and the property owner is interested in development the site as multi-family housing. A letter from the property owner is included in the Appendix of the Housing Element.

Menlo College – 1000 El Camino Real
Menlo College is a private 4-year college located at 1000 El Camino Real sited on 31 acres of property (including 50% ownership of Cartan Athletic Field and Wunderlich Athletic Field) serving over 800 students. All freshman and sophomore students are required to live on campus in rental units. The campus is zoned Public Facilities and Schools (PFS) and abuts the Victoria Manor residential subdivision to the south (R1-A zoning), the MacBain Avenue residences to the west (R1-A zoning), Alejandro Avenue to the north and Menlo School to the south (PFS zoning). The policies within the Housing Element provide that the Town would allow the school development by right at 20 units per acre.

Menlo College currently has 567 beds in 5 residence halls for its students with an additional 288 beds added in the fall of 2022. These units free up existing affordable housing opportunities in the local community. The on-site student housing frees up housing units in the community and addresses the needs of very-low-income students that were experiencing homelessness. The College also has 25 housing units for its faculty and staff and has a waiting list for more rental needs. Most of those housing units are rented at rates affordable to low- and moderate-income households.

In recent discussions between the College President and Atherton Planning Staff, the President indicated that the College is very interested in providing additional housing on campus. He stated that there is always a demand for additional housing, that the existing units are almost always 100% occupied, and that shortage of affordable housing is a barrier to hiring. Funding has also been a barrier to housing production in the past. Through this Housing Element update process, a group of residents have been formed to assist the College with resources to prepare site feasibility studies and commitment to identify funding sources to build the housing. The attached letter from the College President indicates that the College could support 60 to 90 new multifamily housing units. Letter from the College President is included as an appendix. These sites would contribute to fair housing by accommodating moderate and low income school staff including accessible units. The Town will ensure that there are units for staff across the income spectrum, from teaching faculty to janitorial staff. This consideration applies to all premises willing to build affordable housing listed below.

The existing PFS zoning requires a conditional use permit for residential uses and allows multifamily residential uses by right (with the provision of very low and low-income units), subject to Planning Commission review of the location, size, proximity to heritage trees and environmental aspects of the project. There are seventeen existing buildings on the campus with a total floor gross area of approximately 307,700 square feet. The total building footprint area is 269,500 square feet resulting in 29% lot

Town of Atherton 2023-2031 Housing Element – DRAFT 70
January 2023
coverage. The PFS zone allows 40% lot coverage with no maximum floor area ratio.

The site can accommodate several new buildings. Based on discussions with the College President and a review of site improvements, there are multiple sites on campus that are viable locations for multifamily housing.

Site 1: The existing O’Brien surface parking lot at the southwest corner of El Camino Real and Alejandra Avenue is approximately 75,000 square feet (1.7 acres) in area. The site is level and currently contains a paved parking lot. The lot is surrounded by mature vegetation. Construction of a multi-family housing building is feasible at this location with podium parking at ground level and 3 stories of housing above, or below grade parking. The town does not have on-site parking requirements.

Parking would be replaced to meet the needs of the college. The Town will rezone this site to permit 40 units per acre by right with objective design standards. The College has expressed interest in developing 60 dwelling units at this site.

Site 2: There are four residences located on the campus in WWII barracks that are currently utilized for faculty housing. Demolition of these residences would accommodate 30 apartment units, resulting in a net increase of 26 multifamily housing units.

Site 3: In addition to the sites identified above, the College has identified a site interior to the campus that is viable for a multi-story multi-family development of 40 to 60 units. The site, near the Administration Building, is currently used as parking. Additional parking can be developed near the entry to the College off of El Camino Real.

The housing sites on the Menlo College campus are located near a public transportation route (SamTrans bus route on El Camino Real) and would therefore qualify for State mandated reduced parking provisions. To accommodate the new housing development, the zoning will be amended as follows:
● Rezone Site 3 to permit multifamily housing at a density of 40 units per acre and rezone Site 2 to permit multifamily housing at a density of 20 units per acre ● Reduce the minimum front yard setback to 30 feet
● Amend the height limit to allow 4 stories at 48 feet
● Permit multifamily housing by right with objective design standards With the zoning amendment, new multifamily housing would be feasible at the Menlo College campus and would provide housing for a range of income categories, most notable in the very-low to low and moderate income range. The new multifamily housing would also provide accessible units.

Menlo School – 50 Valparaiso Avenue
Menlo School is a private grade 6 - 12 school located at 50 Valparaiso Avenue sited on 26.7 acres of property (including 50% ownership of Cartan Athletic Field and Wunderlich Athletic Field) serving approximately 795 students. The school site is zoned

Town of Atherton 2023-2031 Housing Element – DRAFT 71
January 2023
Public Facilities School (PFS) and currently allows for the development of multifamily residential uses. The policies within the Housing Element provide that the Town would allow the school development by right at 20 units per acre.

The school property abuts the Victoria Manor residential subdivision to the east (R1-A zoning), the Michaels Way residential subdivision to the west (R1-A zoning) and Menlo College to the north (PFS zoning). There are eleven existing buildings on the campus with a total gross floor area of 311,574 square feet. Two housing sites have been identified on the Menlo School campus following a review of site improvements:

Site 1: An approximate 56,000 square foot (1.28 acre) surface parking lot located in the southwest corner of the campus with frontage on Valparaiso Avenue and the school entry drive. A 75-foot setback for buildings higher than 22 feet is required by the zoning along the west property line (adjacent to single family homes). An emergency access road required by the Menlo Park Fire District exists within this 75- foot setback (perimeter fire road). At a density of 20-units per acre, this site could yield 25 dwelling units. With the zoning amendment, new multifamily housing would be feasible at the Menlo College campus and would provide housing for a range of income categories, most notable in the very-low to low and moderate income range.

Parking to meet school demand would need to be provided either below grade or in a structure
Site 2: An approximate 44,000 square foot (1 acre) surface parking lot is located in the southeast corner of the campus with frontage on Valparaiso Avenue and the school entry drive. A 75-foot setback for buildings higher than 22 feet is required by the zoning along the east property line. An emergency access road required by the Menlo Park Fire District exists within this 75-foot setback (perimeter fire road). At a density of 20- units per acre, this site could yield approximately 20 dwelling units.

To accommodate the new housing development, the zoning will be amended as follows:
● Rezone sites 1 and 2 to permit multifamily housing at a density of 20 units per acre
● Reduce the minimum front yard setback to 30 feet (along Valparaiso Road) ● Amend the height limit to allow 4 stories of 48 feet
● Permit multifamily housing by right with objective design standards With the zoning amendment, new multifamily housing would be feasible at the Menlo School campus and would provide housing for a range of income categories, most notable in the very-low to low and moderate income range. The new multifamily housing would also provide accessible units.

Sacred Heart – 150 Valparaiso Avenue
Sacred Heart Schools is a private preschool, K - 12 institution located at 150 Valparaiso Avenue on 60 acres of property serving approximately 1,195 students. The school site currently allows for the development of multiple-family residential uses, and adjacent

January 2023
parcels that may be acquired by the school in the future would likely be rezoned for such a use. There are currently 5 apartment units on the campus and housing for retired Nuns at Oakwood. The school anticipates this facility being renovated in the future to accommodate faculty housing which would be allowed under the new proposed PFS Zoning at 20 units per acre. While the school has a need for faculty and staff housing, it is not anticipated that the school will develop new housing units during this housing element cycle.

Public Schools
Public schools in Atherton also have an identified critical need for teacher and faculty housing. These schools have the opportunity to create housing using the California Teacher Housing Act of 2016. While the Town’s Housing Element does not account for additional housing at these schools over the 2023-2031 Housing Cycle, it is highly likely that one or more of the institutions below will pursue such housing. All public school sites are shown within the PFS Zone on the following Housing Sites Map. Private school sites are circled.

Menlo-Atherton High School
Menlo-Atherton High School is a public four-year secondary school in the Sequoia Union High School District serving approximately 2,400 students. The school and its athletic fields occupy 38.5 acres at 555 Middlefield Road at the corner of Middlefield and Ringwood Avenue.

Laurel School Lower Campus
Laurel School is a public elementary school in the Menlo Park City School District. Its Lower Campus is on 6 acres at 95 Edge Road in Atherton at the corner of Edge and Ringwood Avenue. The Lower Campus serves approximately 326 students in grades K2.

Encinal School
Encinal School is a public K-5 elementary school in the Menlo Park City School District serving approximately 630 students. It is located on 10 acres at 195 Encinal Avenue at the corner of Encinal and Middlefield Road.

Las Lomitas School
Las Lomitas School is a public TK-3 elementary school in the Las Lomitas Elementary School District serving approximately 485 students. It is located on 9 acres at 299 Alameda de las Pulgas at the corner of Alameda de las Pulgas and Camino Al Lago.

Adelante Selby Spanish Immersion School
Adelante Selby Spanish Immersion School is a public K-5 elementary school in the Redwood City School District serving approximately 652 students. The portion of the campus within Atherton is located on 5.5 acres at 170 Selby Lane.

CalWater Bear Gulch Reservoir Site – 120 Reservoir Road CalWater owns and operates 99 acres at the Bear Gulch Reservoir in Atherton. The property is located within the Town’s Park and Open Space (POS) zoning district. This district currently allows caretaker housing with a Conditional Use Permit. Due to the high cost of housing and new employee recruitment, CalWater expressed interest in constructing four new affordable housing units at this site. However, this development is not currently planned within the current Housing Element cycle.

Underutilized Parcels (Further Subdivision and/or SB 9 Subdivision) Sixty-seven parcels listed on the table are residential parcels included as underutilized since they are of sufficient size to be further subdivided according to the existing zoning and lot size limits. Seven of these parcels are vacant and have the capacity to yield 8 new dwellings for above moderate-income households if subdivided and developed in accordance with existing zoning regulations or to yield 16 new dwellings for above moderate-income households if subdivided and developed in accordance with SB 9 regulations.

Sixty of these parcels are developed with one single-family house. Those parcels have the capacity to yield 91 net27 new dwellings for above moderate-income households if subdivided and developed in accordance with existing zoning regulations. Under the allowable provisions of SB 9, these 60 parcels could be split further, with each parcel further allowed development capacity of 2-3 net new dwelling units. It follows that under SB 9, if each parcel were to meet the required criteria for an urban lot split, the overall development capacity could yield a total of 91-242 dwelling units.

Including vacant properties, this puts the potential development capacity for the single-family properties listed on the sites inventory at up to 258 units. The Town projects it will net 10 new above moderate income units from the development of vacant parcels and another 48 above moderate units from traditional and SB 9 lot splits.

Complete Electronic Housing Element Site Inventory Form Included as Appendix 5 27 Each parcel contains an existing house which must be demolished to permit subdivision and development with two new houses. Therefore, net yield was determined by subtracting one existing house from the total site capacity.

3.414 Environmental Constraints Analysis
The analysis of environmental constraints to development of housing is provided in the discussion below.

1. Areas Subject to Flood Inundation in Event of Dam Failure The areas below Bear Gulch Reservoir and along Atherton Channel are subject to flooding if the Bear Gulch Dam were to fail. This dam is located within about 6,000 feet of the Cañada Fault zone and 10,500 feet of the San Andreas Fault zone28.

Residential development is precluded in the area immediately downstream from the dam by ownership by the California Water Service Company and by open space zoning and General Plan designation. None of these sites are included in the Town’s land inventory.

2. Areas Susceptible to Flooding
According to the Federal Insurance Administration, there are no areas in Atherton identified as flood prone. However, in the 1975 San Mateo County “Seismic and Safety Element” of the General Plan, a few areas in the Town of Atherton were identified as being located within the 100 Year Flood Zone. The main concentration of these areas is along the Atherton Channel with other scattered sites in the area west of El Camino Real. Areas susceptible to flooding do not have any impact on development potential.

3. Areas Subject to Wildland Fire Hazard
Areas identified on the Environmental Constraints map as subject to Wildland Fire Hazard are generally west of Alameda de las Pulgas in the vicinity of Bear Gulch Reservoir and along Walsh Road and Reservoir Road. However, none of the Town is in a High Fire Hazard Zone, as defined. Residential building is precluded around Bear Gulch Reservoir because of its ownership by the California Water Service Company, and the open space zoning and General Plan designation. The adopted Fire Code requires all buildings exceeding 1,000 square feet be sprinklered and that roofs be constructed of fire-resistant materials. All buildings in the wildland interface must have fire sprinklers to protect the interface from a dwelling fire incident. In addition, the Menlo Park Fire Protection District inspects the area annually and recommends homeowners to clear combustible vegetation near structures. This constraint requires mitigation but does not prevent residential construction.

4. Areas Subject to Seismic Activity
San Mateo County is in the vicinity of several known active and potentially active earthquake faults. These include the San Andreas and the Hayward faults. All 28 County of San Mateo Geotechnical Hazard Synthesis Map

Town of Atherton 2023-2031 Housing Element – DRAFT 77
January 2023
properties in Atherton have an equal exposure to seismic activity. This constraint requires mitigation but does not prevent residential construction.

3.415 Infrastructure Description
Adequate infrastructure exists throughout the entire Town to accommodate the existing and planned density of development. This includes existing paved streets, sewer, water supply for domestic and fire suppression purposes and drainage facilities.

Available public services include Police, Fire, Parks and Recreation, Public Works, Building Inspection and Town Administration.

There are no sites in the Town of Atherton identified as available for housing that are in areas not served by public sewer systems. Consequently, there are no sites identified as available for housing for any of the several income level households in areas not served by a public sewer system.

All the housing opportunity sites proposed in this Housing Element are on existing developed property connected or adjacent to all city services. Redevelopment of these infill sites may require infrastructure improvements by the city or the developer to upgrade aging infrastructure or to increase capacity. The provision of on-site improvements, such as streets, curbs, gutters, sidewalks, landscaping, utility undergrounding, drainage, water, and sewer infrastructure, are standard conditions of development approval and have not been barriers to housing development in the past. If off-site infrastructure improvements are required, these are the responsibility of the developer if the upgrade is not currently in the Capital Improvement Program.

Water is supplied throughout the town by the Bear Gulch District of the California Water Service. Most of the water provided (93%) is purchased or imported through the San Francisco Public Utilities Commission, with a remaining 7% supplied by Bear Gulch Reservoir. Cal Water’s 2020 Urban Water Management Plan provides detail on available capacity and allocations for each district, with sufficient planned volume through 2045. While planned water capacity is already sufficient to accommodate the town’s RHNA, the town also anticipates greater efficiency of water use resulting from the type of new development proposed. Atherton residences, compared to regional and state averages, use an inordinate amount of water, primarily due to landscaping. As properties are subdivided through SB 9 to create smaller lots, or new units are created with ADUs, the primary source of local water demand will not be increased. It is reasonable to project that new development of smaller units using ADUs and lot splits will serve to reduce average household water consumption. In addition, Cal Water’s management plan projects water consumption for singlePage 1407 of 1727 Town of Atherton 2023-2031 Housing Element – DRAFT 78
January 2023
family residences to decrease over time due to improved appliance standards, plumbing codes, and conservation programs.29
Most Atherton residents receive sewer services from West Bay Sanitary District, with a portion of the town served by the Fair Oaks Sanitation District operated by the County of San Mateo. Capacity for new development is generally analyzed on a case-by-case basis. Improvements to sewer infrastructure to accommodate development are incumbent on the developer and have not been a barrier to projects in the past.

Per Chapter 727, Statues of 2004 (SB 1087), upon completion of an amended or adopted Housing Element, a local government is responsible for immediately distributing a copy of the element to area water and sewer providers. In addition, water and sewer providers must grant priority for service allocations to proposed developments that include housing units affordable to lower-income households.

Chapter 727 was enacted to improve the effectiveness of the law in facilitating housing development for lower-income families and workers. To comply with SB 1087, upon adoption, this Housing Element will be forwarded to the city’s Public Works Department.

3.416 Zoning Appropriate to Accommodate the Development of Housing Affordable to Lower Income Households
The Town is required to provide sites suitable for construction of 204 lower income units (94 very low income, 54 low income and 56 moderate income). Using HCDs approved methodology, the Town assumes that 50 percent of the very low-income unit (47 of the 94) will be required to meet the needs of extremely low-income households.

As described in section 3.812, based on experience in the last three years of the 5th RHNA cycle, the Town expects an average construction rate of 35 Accessory Dwelling Units per year, or 280 new ADUs during the RHNA 6th cycle. The Town expects that these units will be divided between very low-, low- moderate- and above moderateincome categories. It is projected that the number of ADUs produced in the lower income levels would be 168 units; 112 very low to low income and 56 moderateincome units. The zoning code would be amended to accommodate construction of these ADUs with increased height limits, removal of occupancy restriction on pool houses and guest houses and permit two ADUs per property.

The Town's distributions of project ADUs by income category are largely based on data contained in ABAG’s technical assistance paper issued September 8, 2021 entitled, “Affordability of Accessory Dwelling Units.’ The paper was prepared based on a survey conducted by the Center for Community Innovation at UC Berkeley and utilized HCD’s affordability calculator to determine the appropriate income category. 29 https://www.calwater.com/docs/uwmp2020/MPS_2020_UWMP_FINAL.pdf

Town of Atherton 2023-2031 Housing Element – DRAFT 79
January 2023
Atherton is a well-established community with limited land availability, very high housing costs and limited public funding for housing programs. However, the existing land patterns and housing types are very conducive to a successful ADU program.

Minimum lot sizes are larger than average in Atherton thereby providing more opportunities for the construction of ADUs.

In the past two years, a total of 48 new single-family homes were built in Atherton and during this same time frame, there were 44 new ADUs, 3 JADUs, and 7 ADUconversions. The Town believes that this nearly one to one ratio exists because the Town recently modified its regulations to encourage the development of ADUs. In addition, a recent community survey with nearly 18% of households responding indicates an interest by over 200 property owners to construct an ADU on their property over the next 8 years. Accordingly, the Town believes that the construction rate of 35 new ADUs per year over the next 8 years is achievable.

While single-family homes and owner-occupied housing with four or fewer units are typically exempt from the federal Fair Housing Act, the California Fair Housing and Employment Act (FEHA) applies to any residence of one or more households that is being offered for rent or sale. If a homeowner occupies their home and rents out a portion of their home to a tenant, FEHA does not apply so long as only one tenant can live in the home with the owner. However, ADUs are considered separate units from the primary dwelling unit on the parcel and are therefore covered by FEHA. Owners of ADUs cannot discriminate against tenants or prospective tenants because of their status as a member of a protected class.

A second source of housing affordable to lower income households is construction of new multifamily housing on private property. One property has been identified for rezoning to multifamily zoning with density at 10 units per acre. The Town will also adopt an Inclusionary Zoning Ordinance that would require a minimum of 20% of the multifamily units to be affordable to lower-income households. It is projected that 12 new housing units affordable to above moderate-income households will be constructed on these properties during the 6th RHNA cycle, and 4 units would be constructed affordable to lower-income households pursuant to the Inclusionary Zoning ordinance. In addition to providing housing opportunities to lower income households, the Town will encourage the developer to include new accessible units to provide housing resources for disabled households.

A third source of housing affordable to lower income households is construction of multifamily housing on public and private schools. As described in section 3.813, current zoning permits multifamily housing development on properties in the PFS Zoning District (all public and private schools in Town are zoned PFS). The Town will amend the zoning code to accommodate the new housing development by rezoning the properties to permit 40 units per acre at Menlo College Site 1, 20 units per acre at Menlo College site 2 and 20 units per acre at two Menlo School sites. The zoning will also be amended to increase the height limit and reduce setbacks. The Town projects construction of 80 units of multifamily housing units at the private school campuses during the 6th RHNA cycle; 40 units for very-low-income and low income

Town of Atherton 2023-2031 Housing Element – DRAFT 80
January 2023
households, and 20 units for moderate-income households. These properties would also be subject to the Town’s Inclusionary ordinance, although the schools have expressed need to maintain a higher level of affordability to address their staff housing needs.

3.420 Analysis of Zoning that Encourages and Facilitates a Variety of Housing Types As required by State law, the Town allows factory-built housing or mobile homes on permanent foundations under the same terms applicable to other single-family homes in the R-1A and R-1B zones. The Town does not have architectural review/design review of new homes, nor any specific design guidelines new construction is mandated to follow, and consequently does not impose architectural review on factory-built housing. Lastly, and related, there are no on-site covered parking requirements associated with the construction of any type of new housing.

Currently, multifamily rental housing and single-room occupancy units are permitted in the PFS zones when included in an approved master plan and with a use permit.

The Town will amend the zoning code to allow development of multifamily rental housing by right at 20 units per acre or more on the private school sites and adopt a new multifamily overlay zoning district, RM 10 on one private property where there is developer interest to create multifamily housing. The rezoning to allow multifamily housing by right within the PFS zone will remove the private school master plan and use permit process and will streamline the review and approval process for new multifamily housing. Further, the creation of a new RM 10 zoning overlay district will permit multifamily housing by right subject to objective design guidelines. Adding a new multifamily zoning district in addition to the upzoning at the private schools will encourage and facilitate a variety of housing types available to the community including lower income and accessible units. The creation of these new zoning districts is a substantial step in affirmatively furthering fair housing in Atherton and providing a diversity of housing options for the community.

3.430 Identification of Adequate Sites for Emergency Shelters In 2010, Atherton established a zone that meets requirements set forth in SB2 relating to emergency shelters. The Town amended the existing PFS (Public Facilities and Schools) Zoning District to provide for emergency shelters as an allowable use when located within 500 feet of the Town Civic Center. Within this zone shelters are permitted without a conditional use permit or other discretionary action. The zone contains approximately 6 acres, which can accommodate up to three shelter beds, providing adequate capacity to meet the identified need. A typical shelter approximately 1,000 sq. ft. in size is allowed in this zone by right, and the Town has adopted management and other standards as permitted by State law. This site is strategically located in close proximity to transit and services. The site includes the Townpost office, Town hall and library. The library offers many services including free bike and computer loan program. The development standards for an emergency shelter include 34’ height limit, one parking space per bed and the facility is required to be ADA accessible.

3.440 Identification of Adequate Sites for Transitional and Supportive Housing

Town of Atherton 2023-2031 Housing Element – DRAFT 81
January 2023
In June 2010, Atherton amended the zoning code to explicitly state that any use is permitted if required by State law. Under this revision, supportive and transitional housing only need to obtain the same types of permits and approvals as the same type of residential development in that zone. Residential uses, including transitional and supportive housing, are permitted without discretionary permits in the following zones; R-1A and R-1B; and are permitted with a use permit in the PFS zone.

3.450 Identification of Adequate Sites for Farm Worker Housing As stated in previous sections, there are no agricultural jobs and no farm workers living in Atherton. The closest significant location of agricultural employment is located at least 30-minute drive away. Since there is no need for farm worker housing in Atherton, no sites are identified. See the Housing Needs section for more information on farm workers.

3.460 Other Housing Resources
The Town has no financial resources to spend on affordable housing. However, the Town is willing to consult with other agencies such as the County of San Mateo or nonprofit institutions in the County about resources that might be available to the Town for affordable housing. In addition, the Town has decided to develop a Housing Impact Fee that would be utilized by the Town to encourage and support the development of affordable housing opportunities in Town. The Housing Impact Fee would be collected and segregated by law for its intended purpose.

3.500 CONSTRAINTS ON HOUSING
This section contains analyses of potential governmental constraints contained in the Town ordinances, codes and policies that could constitute a barrier to the maintenance, improvement or development of housing for all income levels.

3.510 Governmental Constraints Analysis

3.511 Land Use Controls
The General Plan and Zoning Ordinance of a community are two primary tools for planning and regulating land use.

General Plan - The Town of Atherton updated its General Plan in 2020. The land use character of the Town has remained that of a mainly single family residential and institutional (e.g., schools) nature. The General Plan reveals that a significant constraint to housing development is land availability. There is little vacant developable land in the Town, and most of the Town's land acreage is developed at existing General Plan densities. The lack of land use categories and associated zoning districts that permit multifamily residential development is also considered a constraint to affordable housing development in its traditional sense.

Zoning Ordinance - The Atherton Zoning Ordinance designates land uses, height, bulk, density and parking standards throughout the town. The Zoning Ordinance was designed for consistency with the General Plan. The General Plan's four basic land use designations: Single-Family Residential, Single Family Residential Low Density, Public Facilities and Schools, and Parks and Open Space are directly reflected by the zoning districts of the R-1A (Single Family Residential one acre minimum), R-1B (Single Family Residential – 0.31 acre minimum), PFS (Public Facilities and Schools), and POS (Parks and Open Space). Table HE-4 presents the Atherton Zoning Categories and Standards of density, setbacks, height limits, floor area ratios, lot coverage and parking requirements.

The zoning categories reflect the Town's low-density residential, large lot, single-family character. Commercial and industrial land uses are prohibited. The standards require large setbacks, limited floor area ratios and height restrictions. However, some standards are quite unrestrictive compared to other cities. For example, Atherton does not require on-site parking, nor is architectural or design review required. New single family residential development permits are processed ministerially and most are submitted concurrently for zoning clearing to the Planning Department and building permit issuance to the Building Department which assists in greatly expediting the permitting process. Consistent with State law, the Town allows factory-built housing or mobile homes on permanent foundations under the same terms applicable to other single-family homes.

Currently multifamily residential uses are permitted in the PFS (Public Facilities and Schools) zoning district when associated with primary nonresidential use of property on the same site. As noted previously, multifamily uses in the PFS district would require issuance of a Use Permit by the Planning Commission, but following such approval for

Town of Atherton 2023-2031 Housing Element – DRAFT 83
January 2023
use, could subsequently follow the same concurrent Planning and Building Department development process as described above for single family residential uses. The Town will amend the Zoning Code to alter this process to allow development opportunity at 20 units per acre by right for multifamily residential development on the school properties. In addition, a portion of Menlo College’s parcel will be zoned for 40 units per acre to allow a higher density development to occur. Further, the Town will create a new multifamily zoning district, RM 10 that will permit 10 units per acre multifamily residential development by right subject to objective design standards and inclusionary housing requirements. This is a substantial step in affirmatively furthering fair housing in Atherton and providing a diversity of housing options for the community.

ADUs are permitted in both the R-1A and R-1B zoning districts. The zoning ordinance was amended in 2003 and again in 2020 to make Accessory Dwelling Units permitted by right in the R-1 districts, exempt the ADU from floor area, and for compliance with State law. An accessory dwelling unit is allowed to encroach on 20 percent of the setbacks as the main dwelling and setbacks may be reduced to 4 feet in compliance with State law, however, may be limited in size to that allowed by State law. Detached accessory dwelling units are limited to 16 feet in height and 1,200 square feet of floor area. The consequence of zoning changes has been a significant acceleration in the production of ADUs. SInce these changes have been implemented, approximately 100% of all new single-family homes (averaging 20-25 per year) include a new ADU.

Attached ADUs (additional living quarters inside homes) are permitted by right in both the R-1A and R-1B zoning districts. These may include a bedroom, a bath and kitchen elements (stove, sink, and refrigerator). Accessory dwelling units are commonly constructed in Atherton (approximately 30 - 35 per year).

Currently, the Zoning Title of the Atherton Municipal Code limits full time occupancy “guest houses”, pool houses and similar accessory buildings (occupancy is limited to a maximum of 30-days per year). This could be considered a constraint on the conversion or construction of such accessory buildings to an ADU. During the 2023- 2031 Housing Element cycle the Town will amend the Zoning title to eliminate this occupancy limitation, thus removing this constraint.

* 34’ maximum with increased setbacks and Special Structure Permit The Municipal Code and Ordinance provides a variety of lot sizes with densities ranging from one dwelling unit per five acres to three units per acre. Although the Town's low allowable densities constitute a potential constraint to affordable housing development, the impact is offset somewhat by the relatively large proportion of homes containing accessory dwelling units. In addition, Atherton's single family homes provide opportunities for home sharing. These characteristics of the local housing stock assists the Town in meeting its regional share of affordable housing. Housing associated with the underlying use (including multifamily rental housing and single room occupancy units) is permitted in the PFS (Public Facilities and Schools) Zoning District. As indicated above, the Town will amend the Zoning Code to include two new multifamily zoning districts to provide additional housing opportunities and affirmatively further fair housing. The new zoning districts will allow development up to 40 feet in height with adequate setbacks to accommodate the development and subject to objective design standards.

3.512 Codes and Enforcement
The latest edition of the Uniform Building Code is enforced in Atherton. The Town's Building Department sees that new residences, additions, auxiliary structures, etc., meet all of the latest construction and safety standards. Building permits are required for any construction work. The Town has not adopted any local amendments to the State Housing Law or the Uniform Building Code. The Uniform Building Code is imposed by State law and does not pose an unusually significant constraint to housing development, maintenance or the supply and affordability of housing.

The Town has instituted a code enforcement program. This is primarily a land use enforcement, complaint-based program. Typical complaints and violations relate to noise, construction activity without a Building Permit and parking of contractors’ vehicles and has not resulted in housing being deemed unfit for human habitation or vacated. The code enforcement program does not pose a constraint to housing development, maintenance or the supply and affordability of housing.

3.513 On and Off-Site Improvement Requirements
The on and off-site improvements required for residential development in Atherton are listed below.

Town of Atherton 2023-2031 Housing Element – DRAFT 85
January 2023
Street Width: 20 feet
Curbs and Gutters: Rolled curbs and gutters required for new subdivisions Sidewalks: Prohibited in new subdivisions.

Water and Sewer Connections: Required
Drainage: Storage improvements required to prevent increased runoff during storm conditions (required by the San Francisco Bay Area Regional Water Quality Control Board)
Since Atherton is a completely developed urban area, all streets are paved, water mains and sewer trunks have been installed and major drainage improvements are in place. Atherton’s improvement standards are substantially less restrictive than those imposed by many communities, which often require wider streets and additional offsite improvements. The on and off-site improvement requirements do not pose a constraint to housing development, maintenance or the supply and affordability of housing.

3.514 Fees and Exactions
To assist jurisdictions in meeting requirements for analysis of fees and permit processing, 21 Elements released a survey to all jurisdictions in San Mateo County. The survey asked about potential government constraints to housing, including impact fees, entitlement fees, building permit fees, and permit processing times. In conjunction with that survey, 21 Elements hired Century Urban, a San Francisco based real-estate consulting firm, to examine the cost of land and labor for new housing development in the County.

Combined, those two data sets provide a basis for a preliminary examination of constraints for jurisdictions in San Mateo County.

Participation in the 21 Elements government restraints survey was excellent, with 18 of 21 jurisdictions participating. While not all the respondents answered all the questions, the high overall participation results in a meaningful look at the landscape of government-imposed fees in San Mateo County. 21 Elements distributed the survey in November 2021 and accepted results through February 2022.

The survey asked jurisdictions to calculate fees for three hypothetical housing developments: a single-family house, a 10-unit apartment building, and a 100-unit apartment building.

Single-Family Home – Participants were asked to estimate fees for one of two, hypothetical single-family home developments:
● 2,600-square-foot house with 500-square-foot garage. The house is two stories tall with four bedrooms and two bathrooms. The house is constructed on an

Town of Atherton 2023-2031 Housing Element – DRAFT 86
January 2023
empty lot in an existing neighborhood and requires no significant grading or other complications.
● 5,000-square-foot house with 1,000-square-foot garage. House is two stories tall with four bedrooms and three bathrooms. The house is constructed on an empty lot in an existing neighborhood and requires no significant grading or other complications.

Atherton, along with Woodside, and Unincorporated San Mateo, chose to estimate fees for the larger house as more representative of the community.. All other respondents estimated fees for the smaller house. For purposes of comparison, all the data are presented in the same table, regardless of which size hypothetical house was chosen.

Small Multi-Family – Jurisdictions were asked to estimate the fees for a hypothetical development with 10 units with moderate complexity.

Large Multi-Family – Jurisdictions were asked to estimate fees for a 100-unit development.

The Atherton fees are estimated for the prototypical single-family project are shown in Table HE-5. As shown, Town entitlement fees are significantly lower than other communities due to the streamlined and efficient development review process currently practiced.

Development Impact Fees are one-time charges levied on new developments and serve as tools to mitigate the impacts of new development by funding a range of capital programs required to address needs related to that development, including transportation, parks, and utilities (such as water, sewer, and storm drain). Other than a park in lieu fee under the Quimby Act for subdivisions, the Town does not currently have any impact fees; however, projects that connect to either sewer district are charged fees and construction costs that are outside of the Town’s control.

In Atherton development fees are charged for both planning review and building permits. Planning fees are charged in order to recover the costs associated with the administration of the Town’s land use regulations. Planning fees for review of projects that do not require Planning Commission action (i.e., Staff level) are charged a flat fee shown in the table below.

Planning fees for projects that require Planning Commission action consist of a nonrefundable fee and a deposit, against which professional planning staff charge to provide review services. Charges currently range from $125 to $236 per hour depending upon the level of personnel involved in the review. Unused portions of the deposit are returned to the applicant at the end of the process. The fee structure reflects the Town’s actual cost for the service. The Town reviews its fee structure and levels on a regular basis to ensure they reflect the cost of delivering services. Typical planning fees are shown in the table below.

The Atherton planning fees are less than other San Mateo County jurisdictions, are consistent with similar charges in other small jurisdictions, and do not pose a significant constraint to housing development, maintenance or the supply and affordability of housing. The Town’s policy objectives propose to waive planning fees for new ADUs.

Building fees are charged to cover costs associated with checking that the building plans conform to requirements of the Uniform Building Code (UBC) as well as costs associated with conducting building construction inspections. Fees charged for building permits are based on the valuation of construction. The fee structure reflects the Town’s actual cost for the service. The Town reviews its fee structure and levels on a regular basis to ensure they reflect the cost of delivering services. Currently new construction valuation is determined by use of a standard factor of $350 per square foot for habitable space and $125 per square foot for non-habitable space. The same factor is used for remodeling projects; however, the Building Department has the option to adjust the permitted value to the actual cost of the remodeling provided evidence is presented in the form of an executed contract substantiating the value.

The actual building permit fee is determined using the following formula: where construction is valued over $1,000,000 the fee is calculated as $6,193.74 for the first $1,000,000 plus $4.03 for each additional $1,000 or fraction thereof. An additional 45% of the building permit fee is charged for plan checking. For example, where construction is valued over $1,000,000 the fee is calculated as $6,193.74 for the first $1,000,000 plus $4.03 for each additional $1,000 or fraction thereof. An additional 45% of the building permit fee is charged for plan checking.

While not imposed by the Town, local school districts charge a fee that is based on the square footage of new construction and must be paid prior to issuance of the building permits. The purpose of the fee is to compensate the school districts for the costs associated with the demand for additional services and classroom space generated by new residential construction. The Sequoia Union High School District collects the fees and distributes a portion to one of the three elementary school districts serving Atherton (i.e., Las Lomitas School District, Menlo Park City School District and Redwood City School District). Currently the Sequoia District is $3.79 per square foot of residential construction with $1.52 (40%) distributed to the Sequoia District and $2.27 (60%) distributed to the Menlo Park District, Las Lomitas or Redwood City Districts.

The Town does not have any park, open space, parking or other similar development or impact fees. Nor does it have any in-lieu housing or other fees, below-market-rate housing requirements or specific land dedication requirements for streets, public utility rights-of-way, easements, parks or open space.

A recent survey by 21 Elements30 revealed that a 5,000 square foot house built in Atherton would have construction fees of $16,941 and no entitlement or impact fees 30 21 Elements: Development Fees Survey Summary, April 2022
