Housing Element Update for 2023-2031
The Town of Portola Valley Housing Element identifies and analyzes existing and projected housing needs and contains the official policies for the preservation, conservation, rehabilitation, and production of housing in the Town of Portola Valley. The current Housing Element covers the Planning Period from January 2023 through January 2031. It was adopted in its current form by Town Council on January 24, 2024, and certified by the State Department of Housing and Community Development (HCD) on January 30, 2024. It was re-certified on May 28, 2025 following Zoning Code amendments to implement the updated Housing Element. The Town has made good faith compliance progress on Housing Element implementation.
The Draft Housing Element Amendment (Draft Amendment) was developed in late 2025 and was available for public review beginning on Tuesday, December 23, 2025 through Wednesday, January 14, 2026. The Draft Amendment includes changes to the Sites Inventory to remove the Dorothy Ford Park and Open Space from the Sites Inventory and reallocating the same number of potential housing units on that site to three other sites.
The proposed revisions to the Sites Inventory consist of adding two sites. These include Village Square at 884 Portola Rd and Skyline Open Space (North of 19501 Skyline Blvd). Modifications to the unit count and income levels are proposed for the Christ Church at 815 Portola Valley Rd, which is already included in the Sites Inventory. The three sites are proposed to be zoned as Mixed‐Use High Density, which will be a new zoning district. The total number of units on the Sites Inventory, after removing the Dorothy Ford Park and Open Space and making the changes described above, has not changed and remains the same at 120 total units.
On December 4, 2025, the proposed Draft Amendment was presented for preliminary review at a special Town Council meeting to receive information and provide direction to staff. Public comment was also received during this meeting.
On December 23, 2025, the Draft Amendment was posted for public review and the public was invited to submit written comments on the Draft Amendment during the public review period from Tuesday, December 23, 2025 to Wednesday, January 14, 2026.
On January 7, 2026, at 7:00 PM, the proposed Draft Amendment was presented for preliminary review at a Planning Commission meeting to receive information. Public comment was also received during this meeting.
On January 14, 2026, at 7:00 PM, the proposed Draft Amendment was presented at a Town Council meeting and the public was invited to make comments. At this meeting, the Town Council authorized staff to send the Draft Amendment to HCD.
On January 23, 2026, the Town sent the Draft Amendment to HCD for review.
On March 25, 2026, the Town received a comment letter from HCD outlining its review of the Draft Amendment. The letter can be found here.
The agendas and staff reports are posted on the Town Calendar webpage.
There will be additional public meetings on the Draft Housing Element Amendment in 2026 before the Council considers taking final action to approve it. If you would like to receive future updates, please subscribe to the Town eNotice for Housing News.

Housing Element Sites Inventory Revision
The certified Sites Inventory includes the vacant portion of the Dorothy Ford Park and Open Space. This site was identified as having the potential to be developed with up to 50 units of Very Low-Income housing units. The Town explored alternative sites within the Town that could accommodate the number of units specified for the Dorothy Ford Park and Open Space. Additionally, as the Town staff analyzed the feasibility of development of this site with housing to implement the certified Housing Element, issues were identified that affected the feasibility of the development of up to 50 units at this site. The primary reasons for this conclusion are the limited development area when creek and scenic setbacks were considered and the irregular shape of the remaining area.
To ensure continued compliance with State Housing Element law, the Draft Amendment will remove the vacant portion of the Dorothy Ford Park and Open Space site from the Sites Inventory and reallocate the units to a combination of newly identified housing opportunity sites and an existing site with increased development capacity. These sites are proposed to be rezoned at densities sufficient to accommodate the Town’s remaining RHNA at all income levels, including Very Low-income units. The Draft Amendment reflects these changes.
The proposed revisions to the Sites Inventory include the following three replacement sites:
- Village Square - 884 Portola Rd. The 2.3-acre parcel is currently developed with older one-story low intensity commercial uses. The Sites Inventory being considered identifies the potential for the site to accommodate 20 Very Low Income (VLI) units and 5 Above Moderate Income (AMI) on a 1.25-acre developable area. The property owner, who is a local developer, has expressed interest in developing housing that is compatible with the main commercial building and tenants.
- Christ Church - 815 Portola Valley Rd. The 2.93 acre site is already identified in the Sites Inventory to be able to accommodate 6 Above Moderate Income units. The proposed changes would result in the site being identified to accommodate one (1) Above Moderate Income unit and 14 VLI units on a 0.75-acre developable area. The Church has received a grant to explore housing development and is currently reviewing potential options.
- Skyline Open Space (North of 19501 Skyline Blvd). The 14.65 acre parcel is currently vacant, but has an approximately 0.8-acre developable area based on the Housing Element and State law site criteria. This area is identified to accommodate 16 VLI units.
Collectively, the proposed replacement sites maintain the total number of housing units identified in the Sites Inventory and continue to demonstrate the Town’s ability to meet its RHNA. The overall number of projected housing units in each income category will remain the same as in the existing Housing Element adopted in March 2024.
All three replacement sites are proposed to be zoned as Mixed-Use High Density, which to date is not present in the Town’s zoning ordinance. A new Mixed-Use High Density district will be created to accommodate a new density range proposed only for the Village Square, Christ Church, and Skyline Open Space sites. This new mixed-use zoning provides flexibility to property owners and could result in new commercial services to meet the needs of any future residents and the surrounding area. It could also increase the potential tax revenue for the Town.
On December 4, 2025, the Draft Amendment was presented at a special Town Council meeting for Town Council to receive information and provide direction to staff on the Draft Amendment. Town Council agreed with the sites inventory revision, which proposed removing the vacant portion of the Dorothy Ford Park and Open Space site from the Sites Inventory and reallocating the units to Village Square, Christ Church, and Skyline Open space sites. Town Council’s direction included changing the density range for the new draft Mixed-Use High Density zoning district from 20-23 du/acre to 20-25 du/acre, which would be applied to the Village Square, Christ Church, and Skyline Open Space sites.
Draft Housing Element Amendment and Associated Items
The Draft Amendment and associated items to implement it are being prepared concurrently, and include the following that require Town Council approval:
- Draft Housing Element Amendment
- General Plan Amendment
- New Mixed-Use High Density Land Use Classification for the Village Square, Christ Church, and Skyline Open Space sites. Amendments to the Town General Plan Comprehensive Plan Diagram and classifications will be prepared in early 2026.

- The Town staff and consultants anticipate preparing an addendum to the approved Initial Study/Mitigated Negative Declaration (MND)[1] that was prepared for the Housing Element to include the new sites and rezonings. Fehr & Peers will work closely with the project team to review the Vehicle Miles Traveled (VMT) analysis prepared for the MND and prepare a quantitative narrative letter. Environmental Collaborative will work with the project team to review and update the Biological Resources analysis with an updated memo and updates to the California Natural Diversity Database (CNDDB) records and maps.
All these items will be presented for Planning Commission and Town Council consideration and action in 2026.
The Opt-in Housing Diversification Program in a Program in the Town's Housing Element. It was created to satisfy the State housing element law requirement that the Town provide housing opportunities dispersed throughout the community. The main goal of the Opt-in Housing Diversification Program is to help encourage diverse housing development and types across Portola Valley.
Note the program is not currently available and is targeted to go into effect in September 2025. Before the program can go into effect, objective design and development standards, incentives, and process to implement the program needs to be established, which is anticipated to be completed by June 2025.
Please view the comprehensive FAQ document below. The map of potentially elligible parcels is a rough estimate of sites elligible for the program. Any property owner wishing to participate in the program will be required to conduct actual site anlysis in advance to confirm elligibility.

What is a Housing Element?
Housing Elements are housing plans that are one part of the General Plan – a guide to all the ways each city, town or county is planned and managed, from our roads to our parks and neighborhoods. With an update required every eight years by the State of California, this Housing Element update will create a foundation for all the policies and programs related to housing.
While city governments do not build housing themselves, they create the rules that affect where housing can be built, how much, and how it gets approved. Each jurisdiction’s housing plan needs to help ensure that there will be enough capacity and supportive policies to meet the projected need over the next 10 years.
The Housing Element update is an opportunity to address what has happened before and change course based on what a community needs and values now.
