Report #: 2512-5738
TITLE
San Antonio Road Area Plan Land Use and Transportation Alternatives Study Session. CEQA
Status: Exempt under CEQA Guidelines Section 15262.
RECOMMENDATION
Staff recommends the Architectural Review Board (ARB) conduct a study session to:
1. Review and comment on the draft San Antonio Road Area Plan land use and mobility
alternatives; and
2. Provide feedback to staff on preferred land use and mobility alternatives to inform City
Council discussion.
EXECUTIVE SUMMARY
The San Antonio Road Area Plan (Area Plan) draft land use and mobility alternatives (illustrated
in Attachment A) provide high-level options for development in the plan area. Topics include
allowed uses, bicycle/pedestrian facilities, residential density, building heights, commercial
office and retail development areas, outdoor space, and roadway improvements. ARB feedback
on key project considerations and approaches are critical for the City Council to select the
preferred alternatives.
PROJECT DESCRIPTION
The purpose of the Area Plan is to develop an integrated land use and transportation approach
to guide new development in the 275.3-acre plan area along and adjacent to San Antonio Road.
The Area Plan objectives include increased housing production, transportation and mobility
improvements, outdoor space, commercial and retail nodes, infrastructure, and sustainability
measures. The creation of this plan implements policies and programs of the City’s
Comprehensive Plan and the 2023-2031 Housing Element (Housing Element). The Area Plan will
establish policies, development standards, design guidelines, and the public infrastructure
necessary to accelerate the envisioned growth and development. The Area Plan builds on other
Item 2
Item 2 Staff Report

Item No. 2. Page 2 of 7
planning efforts, including the 2030 Comprehensive Plan, the 2022 Sustainability and Climate
Action Plan, the Housing Element, the 2025 Safe Streets for All (SS4A) Safety Action Plan, and
the 2026 Bicycle and Pedestrian Transportation Plan update (currently in process).
BACKGROUND
1 PDAs are locally created to support regional
goals set forth by the Association of Bay Area Governments (ABAG) and the Metropolitan
Transportation Commission (MTC), as described in Plan Bay Area. Plan Bay Area outlines the
Bay Area’s Regional Growth Framework, Regional Transportation Plan, and Sustainable
Community Strategies through 2050 and beyond. Key goals of PDAs include encouraging and
guiding growth around transit and connecting housing to jobs and areas of interest.
2 Pedestrian and Bicycle Advisory Committee; and
City/School Transportation Safety Committee in 2025. A Community Survey was conducted in
October 2025, and the first Community Workshop was held on October 23, 2025.

from late February through March 2026. The feedback from these advisory bodies and the
public will be presented to the City Council at a study session on April 6, 2026.
ANALYSIS
The development of land use and mobility alternatives is a critical step toward creation of an
area plan. These alternatives explore differing priorities and tradeoffs, including housing and
commercial mix, housing densities, building heights, outdoor spaces, retail, and bicycle and
pedestrian facilities. Once preferred alternatives are selected, the Area Plan will have its high-
level concepts in place which will be further developed in the draft plan. The Area Plan will
ultimately include more granular policies, and development standards will be developed in later
phases of the project.
Land Use
For the land use alternatives, the project team has divided the 275.3-acre plan area into
districts which could be seen as distinct development areas. Some of these areas are
considered not likely to redevelop during the next 25 years, due to factors such as how recently
the current property was developed, institutional uses, and disparate ownership. Other areas
have a higher probability of redevelopment. Please refer to the map in Attachment A, Page 18,
for the specific locations of these development areas. The development areas are:
Primary Sub-Areas (High Development Potential Areas)
The primary focus of the land use alternatives is on four high development potential areas
listed below. These areas are considered most likely to change. The project team has created a
series of options (or alternatives) to consider illustrated in Attachment A on pages 20-58.
Central San Antonio – is generally the area along San Antonio Road between East
Charleston Road and Byron Street, excluding the Greenhouse. This area includes several
pipeline residential development projects, additional sites likely to redevelop (such as
the Magnussen Toyota site at 690 San Antonio Road), and only a handful of sites
unlikely to redevelop (such as the two recently constructed hotels at 744 and 750 San
Antonio Road). Many properties contain one- to two-story commercial development.
These are explored in pages 22-26 of Attachment A.
South Fabian – The portion of Fabian Way on either side of Charleston Road, this area
includes the Taube Koret Campus for Jewish Life, a private school, and some of the most
Item 2
Item 2 Staff Report
Packet Pg. 9
Item No. 2. Page 4 of 7
recently constructed multi-family housing, none of which is likely to redevelop.
However, there are several low-rise commercial spaces and surface parking lots which
have high development potential. This area contains some pipeline residential
development projects. These are explored in pages 27-31 of Attachment A.
North Fabian – The portion of Fabian Way closest to U.S. 101; this area contains 2-3
story office buildings (including the Maxar Site at 3825 and 3875 Fabian Way) and a
private school. While the school is unlikely to redevelop, the owner of the Maxar Site is
currently seeking a buyer, with residential development likely to be considered as part
of any redevelopment. These are explored in pages 32-39 of Attachment A.
CTI – The area containing Commercial Street, Transport Street, and Industrial Avenue
(CTI), bounded by San Antonio Road, U.S. 101, East Charleston Road, and the City’s
border with Mountain View contains a number of small lot, one- to two-story
commercial buildings. While there are no active development applications in this area,
there is developer interest in consolidating lots in this area. A 16-acre mixed-use
development is currently proposed in Mountain View adjacent to this area, and there is
a unique opportunity to work across jurisdictions in developing a new neighborhood in
this area. These are explored in pages 40-58 of Attachment A.
Secondary Sub-Areas (Limited Development Potential Areas)
The Area Plan will also consider land use alternatives in other areas which have more limited
development potential, listed below. The project team has created a series of options (or
alternatives) to consider, described in more detail in Attachment A on pages 63-67.
East and West Bayshore – The area bounded by East Bayshore Road, San Antonio Road,
and the Baylands Nature Preserve currently contains a number of low-rise office
buildings and the HomeKey transitional housing site. Separated from the rest of the Plan
Area by U.S. 101 and in close proximity to the Bay, this area is less desirable for
increased residential development. The single parcel along West Bayshore Road
adjacent to the U.S. 101 bike/ped bridge also currently has a commercial office use and
is not well connected to the surrounding community.
Alma – The portion of the Plan Area along Alma Street contains a small townhouse
development and two faith-based organizations with larger parking lots. While state
laws have made it easier to develop housing in proximity to Caltrain stations, this area is
still considered less likely to redevelop, with the possible exception of the two faith-
based sites. State law has also made development of 100% affordable housing projects
easier on such sites, however, given the current scarcity in federal and state funds for
affordable housing, local funds would likely be required to make projects on these sites
feasible.
Stability Areas (redevelopment not anticipated)
Item 2
Item 2 Staff Report
Packet Pg. 10
Item No. 2. Page 5 of 7
There are also sub-areas within and adjacent to the plan area which are considered highly
unlikely to redevelop due to factors such as lot size, ownership, and/or historic designation. See
Sub Area Alternatives map on page 18 of Attachment A.
Greenhouse – The Greenhouse (777 San Antonio Road) and the Greenhouse II (765 San
Antonio Road) are a series of individually owned townhomes constructed in the 1970s.
Green Meadow – Green Meadow is one of Palo Alto’s mid-century subdivisions
designed by Joseph Eichler. While it is listed on the National Register, it is not a
designated district on Palo Alto’s Inventory. Green Meadow is outside of the plan area,
but within the Senate Bill 79 (2025) development area.
South San Antonio – South San Antonio is generally the area along San Antonio Road
between Byron Street and Nita Avenue. This area contains individually owned
townhomes, low-rise apartment buildings, and private schools.
Mobility
San Antonio Road (E. Charleston Road to Middlefield Road) – This segment currently
includes an approximately 100+ foot public right-of-way (ROW), four travel lanes (two in
each direction), a raised median, and on-street parking that transitions to turn lanes at
intersections. Sidewalks are provided on both sides of the street. Bicycle travel is
currently accommodated via Class III shared-lane markings (“sharrows”), where people
bicycling and motor vehicles operate in the same travel lane – there are no dedicated
on-street bicycle lanes or separate bicycle facilities on this segment. The alternatives
Item 2
Item 2 Staff Report
Packet Pg. 11
Item No. 2. Page 6 of 7
presented in pages 92-99 of Attachment A provide three concepts to enhance
pedestrian and bicycle facilities while maintaining existing general-purpose vehicle
travel lanes along the City’s east-west truck route.
E. Charleston Road (south of San Antonio Road) – This segment functions as a key
connection to the City of Mountain View and currently provides pedestrian and bicycle
accommodations along the corridor (e.g., sidewalks and bike lanes). The alternatives
presented on pages 106-113 of Attachment A present two concepts to enhance
pedestrian and bicycle facilities along this segment.
Staff is requesting feedback on which of the Area Plan alternatives are preferred, and which are
not preferred. Additional feedback is welcome on other alternatives explored in Attachment A.
This feedback will be provided to the City Council at a study session scheduled for April 6, 2026.
NEXT STEPS
Feedback from the ARB, other appointed boards, committees, and commissions, and the
community (through the Community Advisory Group (CAG), community workshop, online
survey, and other public outreach efforts) will be presented to the City Council at a study
session scheduled for April 6, 2026. Once the City Council provides direction, the project team
will next begin creating more detailed policies and standards which will return to the
community and advisory bodies, likely in late 2026.
POLICY IMPLICATIONS
Several of the City’s 2030 Comprehensive Plan policies relate directly to the Area Plan. Policies
L-1.10, L-2.2, L-2.3, L-2.4, L-2.6, L-2.11, L-2.12, and L-3.4 relate to growth management,
sustainable communities, and neighborhood character. Policies L-4.5, L-4.16, and L-5.4 relate to
commercial centers and employment districts. Policies L-6.6 and L-6.7 relate to the design of
buildings and public space. Policies L-8.6, L-9.3, L-9.6, and L-9.7 relate to parks, streets, and
public spaces. Additionally, the 2023-2031 Housing Element includes Program 6.6(C) calling for
the City to prepare an area plan for the San Antonio Road Corridor and increase housing
opportunities. The Housing Element also identifies 53 Housing Opportunity Sites within the Plan
Area and emphasizes increasing housing in close proximity to the San Antonio Caltrain station.
The City has also adopted a Housing Incentive Program (HIP) in 2019, which was updated in
2025, as a local alternative to encourage multi-family and mixed-use residential development.
The HIP currently covers significant parts of the Plan Area.
STAKEHOLDER ENGAGEMENT
The project team understands that Community Engagement is the key to the success of the
planning effort, in addition to the technical, design, and expertise provided by subject matter
experts. The project team has created a robust community engagement strategy, which
includes a dedicated webpage, social media and email announcements, formation of the CAG
and Technical Advisory Group (TAG), stakeholder interviews, community workshops, surveys,

Overall Design Strategy
Redevelop/infill existing low-density commercial with
high-density residential to create new neighborhoods
Create new outdoor spaces and "third spaces"
with neighborhood serving retail and amenities
Improve transit service to community destinations and
access to Caltrain
Improve ped/bike experience, safety and connectivity on all
streets and intersections
The overall urban design strategy is to take the areas with the most
potential for future development and create new neighborhoods in
those areas, including amenities such as parks and more street trees.

Focus on Corridors: Primary interventions will focus on the major
street corridors: San Antonio Rd, E. Charleston Rd. and Middlefield Rd.
Where possible, new connections will be made to increase walkability
Block Size: Reduce block size to create more walkable and connected
neighborhoods
Improve connectivity by adding mid-block pedestrian paths/paseos in
the following areas:
•CTI Area: At least one connection from: San Antonio to Commercial; Commercial to
Industrial; Industrial to MV Project
•North Fabian Way:
•One connection from Fabian Way to San Antonio Rd;
•Add pedestrian walkway or new street connecting to Fabian Way per the
Objective Design Standards (at least one ped connection every 300 feet)
•San Antonio Road: Explore connection to Wyandotte Street
•Caltrain access: Improve connections at Nita Avenue and coordinate with Google and

apartment buildings to achieve average density
•Alt M-B2: 60 du/ac (no building type with less than 30 du/ac net density)
•Would likely push development of more 3-8 story rental apartment buildings
•Would push for-sale component into denser “townhouse over podium” building type
Height
•Alt M-C1: Allow up to 60 feet (status quo)
•Alt M-C2: Allow up to 90 feet (maximize mid-rise constructure type)
•Alt M-C3: Allow high-rises, up to 160-250 feet
•Limited financially feasibility, but provides flexibility and could be desirable for the
right developer
•Hish-rise construction is more expensive, but often pencils out at 160+ feet

Challenges
•Parcels are small with multiple owners; ownership aggregation is

•Small parcels are less feasible for residential development
•Wider front setbacks are needed to improved sidewalks and
increase tree canopy
Opportunities
•Allow higher value land uses (office) in exchange for creating new
outdoor spaces
•Distribute new outdoor spaces evenly across all parcels (require
front yard “mini parks” on all parcels through requiring larger

Alt CTI -A3 | Configuration: Large Central Park
KEY CONSIDERATIONS
•Feasibility. A large outdoor space would
require maximum parcel aggregation and
additional height or higher-value land
uses such as office to “pay” for the
larger, consolidated outdoor space. This
configuration is likely hardest to achieve.
•Size. A 2-acre park may be very difficult
to achieve in one location. If one larger
outdoor space if preferred, the size may
need to be evaluated for feasibility.
•Programming of uses. A larger outdoor
space allows for a wider variety of
program elements, activities, and
increased greenery/ landscaping.
•Reduced noise and safety concerns.
Supports comfort and safety for passive
recreation, children’s activities, as well as
community events.

Land Use Trade-Offs in CTI
Allowing New Office Along with Residential for New
Mixed-Use Projects
Restricting New Office, Allowing Only
Residential/Residential Mixed-Use
Office is the most desirable use in much of Palo Alto from a
developer perspective, with townhouses most desirable in some
locations. By allowing a mixed-use project to include office in
addition to residential, the feasibility of a project increases, and
offers an opportunity to negotiate the provision of community
benefits such as outdoor space.
High-density residential and residential mixed-use projects
(residential above ground floor commercial) face
feasibility challenges in high-value markets such as Palo Alto.
Feasibility is further impacted if projects are required to provide
community benefits like outdoor space, new connections on
private property, etc.
Possible outcomes of allowing office:
-Improve project feasibility, ensuring that redevelopment
happens in the near future.
-Deliver residential units sooner as part of redevelopment.
-Provide more space for parks/plazas/outdoor space.
-Provide more space for new connections (using private
property)
-Provide other community benefits such as streetscape
improvements.
Possible outcomes of restricting office:
-Redevelopment would likely take longer.
-Larger residential projects may not develop without a
corresponding higher-value product (office or townhomes).
-Lower feasibility would likely mean smaller-scale development
on scattered parcels without lot consolidation.
-Incremental development without lot consolidation is unlikely
to produce community benefits such as
parks/plazas,infrastructure improvements.
