We need your help to build a community map!

Communities of Interest are the building blocks of the redistricting process.

Communities of Interest are concentrated populations which share common social and economic interests that should be included within a single district for purposes of effective and fair representation. The 2021 Advisory Redistricting Commission (Commission) and the Board of Supervisors invite community members to submit a Community of Interest (COI) Forms and/or Maps. Submissions will become part of the public record, posted on this page, and reviewed by the Commission to inform the drawing of new supervisorial lines. Community members are also encouraged to submit a draft map at https://districtr.org/event/Santa_Clara_County. Maps must be submitted by October 25, 2021 to be considered by the 2021 Advisory Redistricting Commission at their final meeting on October 27, 2021. To view public community and draft maps submitted by the community, please visit  www.sccgov.org/2021redistricting/COI.

Present Your Community

Sign up to speak at a meeting of the 2021 Advisory Redistricting Commission by emailing the redistricting team at [email protected].

Inform Your Community

Help spread the word so your neighbors and friends can participate in the redistricting process. The County will be sharing content after each Commission meeting and below is sample content that can be used:


 As the community submits Public Comment, Community of Interest Forms, Communities of Interest maps, and proposed district maps they will be added to the redistricting website. They will also be noticed at the next scheduled meeting of the 2021 Advisory Redistricting Commission.

What is a Community of Interest?

California law defines a Community of Interest as a population which shares common social and economic interests that should be included within a single district for effective and fair representation. We need you to submit your Community of Interest Form describing where people with your shared social and economic interests live to inform the drawing of new supervisorial districts.


Some examples of Communities of Interest may be:

  • Senior citizens

  • Recent immigrants from the same country/region

  • LGBTQIA+ communities

  • College students living near campus

  • Residents who share a common language or culture

  • People who use the same public transportation

  • People who live in an industrial, rural or urban area

  • People who use the same parks and recreation areas


How Communities of Interest shape future County of Santa Clara’s Supervisorial Districts

Every ten years, U.S. Census data is used to redraw the County of Santa Clara's supervisorial district boundaries. The Board of Supervisors established the 2021 Advisory Redistricting Commission to ensure robust community participation in the redistricting process. Communities that share common interests, cultural ties, or other social and economic similarities are the building blocks of supervisorial districts, The Commission wants to ensure the County’s districts consider your community and wants to hear from you how boundaries should be drawn. Complete this form to tell the Commission about your community of interest and help ensure one person, one vote.


Why is Your Community of Interest important in the redistricting process?

The County serves the community in many ways: providing safety net services such as access to affordable housing, healthcare, and child welfare services; overseeing land use in unincorporated areas; and protecting public health and safety. Communities of interest are kept together in districts as much as possible to ensure they can influence those policy decisions of the Board of Supervisors. The Commission wants to know:

  1. Does your community have a shared culture, interests, activity, business, or bond?

  2. Does your community live in a concentrated area? Can you draw your community on a map? Is there density within your community (many people in your community living closely together)?

  3. Describe how your community is affected by policy decisions made by the Board of Supervisors. (County services include housing, health care, elections, parks and recreation, child welfare, and public benefits)

It is important to remember that your input can best be used by the Commission to draw new maps if it addresses all three of these questions to describe your community of interest.
