Contra Costa County Redistricting Process Final Supervisorial Map Adopted

by ECT

Martinez, CA – Contra Costa County’s Redistricting effort is a once-a-decade process of redrawing the boundaries for Supervisorial districts after the U.S. Census.

As part of that process, the County’s fifth Public Hearing on Redistricting was held on Tuesday, November 23, 2021. At the November 23, 2021 Public Hearing, the Board of Supervisors voted unanimously to adopt a Supervisorial Map with new district boundaries for Contra Costa County.

Redistricting is the regular process of adjusting the lines of voting districts in response to accordance with population shifts within the County. Every ten years, after the decennial census, supervisorial districts must be redrawn so that each district is substantially equal in population. This process is important in ensuring that each Supervisor represents about the same number of people.

Redistricting is based on the U.S. Census data, which was released in legacy format on August 12, 2021. The actual drawing of Supervisorial District Maps requires the official California State Adjusted Redistricting data, which was released September 20, 2021 and includes updated data to ensure that individuals in the prison population are counted by each jurisdiction.

“The Contra Costa County Board of Supervisors thanks the community for its participation in this decennial process,” said Board Chair, Supervisor Diane Burgis. “We have been committed to a robust Redistricting and public outreach process with public hearings, a dedicated website at CoCoRedistricting.org, public workshops, and multiple ways for the public to share input, including an online mapping tool to draw maps and submit comments. We want to thank you for staying informed and playing a role in this important process.”
