BOARD SELECTS "90195" AS THE SUPERVISORIAL DISTRICT MAP
December 7, 2021
The County of Santa Clara Board of Supervisors voted to approve new supervisorial district boundaries at its meeting Tuesday. The new supervisorial district boundaries balance population amongst districts based on data from the 2020 US Census. A vote on the final resolution for adoption to implement the new maps will be Tuesday, Dec. 14. The new supervisorial district boundaries will take effect on January 13, 2022, thirty-days after adoption by the Board of Supervisors. County staff will update county resources and information post-adoption to reflect the new boundaries.
Draft Plan 90195
The population of each district is different by 4.1% across all boundaries (standard deviation), maintains a majority-minority Asian and Pacific Islander voter representation in District 3 (50.6%) and has a Latino influence in District 2 (49.5%). There are several changes from previous district boundaries that will be instituted on Jan. 13. The most notable changes are:
- The City of Sunnyvale will be entirely located in District 3,
- previously it was split into Districts 3 and 5; and
- The Town of Los Gatos, the City of Monte Sereno, the Lexington Hills area, and the Almaden Valley neighborhood in the City of San José will move from District 1 to District 5; and
- The community of Evergreen in the City of San José will move from District 3 to District 1.
Highlights of the plan include:
- Total Plan Deviation: 4.14%
- API CVAP: District 3- 50.6%
- Latino Influence: District 2- 49.5%
- 1 City/CDP Splits
- City of San José: All 5 Districts
- Unincorporated: All 5 Districts

County of Santa Clara's 2021 Redistricting Process
Every 10 years, the County redraws supervisorial district boundaries, taking into account population changes reflected in the decennial Census. The County has appointed the 2021 Advisory Redistricting Commission for the 6-month redistricting effort to redraw the County’s five supervisorial district boundaries. The Board of Supervisors established the formation of a 15-member commission to hold virtual public hearings and mapping sessions, collect community input, and recommend to the Board updated placement of the district boundaries.
The 2021 Advisory Redistricting Commission received over 200 pieces of community of interest testimony, draft maps, and public comments. Draft maps submitted through the public portal can be reviewed at https://districtr.org/event/Santa_Clara_County. The Commission presented their recommendations to the Board of Supervisors on November 2, 2021 regarding the placement of the supervisorial district boundaries and serve until the completion of the 2021 supervisorial redistricting process.
This website will be updated as the redistricting process moves forward, so please check back for more information. If you would like to receive updates and additional information, please email [email protected].
