[ARCHIVED] Join Us for an Online Mapping Redistricting Workshop

Redistricting Map and URL

Redistricting is the once-a-decade process of redrawing the boundaries for Supervisorial districts after the U.S. Census. 

The Board of Supervisors is seeking input about Communities of Interest. State law defines a “Community of Interest" as "a population that shares common social or economic interests that should be included within a single supervisorial district for purposes of its effective and fair representation. Communities of interest do not include relationships with political parties, incumbents, or political candidates."

One of the guidelines for drawing district boundaries is to learn about communities across the County. To the extent practicable, the County will aim to keep each community of interest together in a district. Learn more about Communities of Interest.

 A series of Online Mapping Workshops will be held to assist residents in drawing and submitting Communities of Interest to be considered in the County’s Supervisorial Redistricting Process. The workshops will be hosted by DistrictR, the online mapping tool the County is making available to provide an easy way to draw and submit maps and comments. 

 The Online Mapping Workshop dates are: 

The County’s second Redistricting Public Hearing will be held on October 5, 2021 at 9 am. It will be available via Zoom, online, and on Contra Costa Television channels. Learn more, including how you can provide input, at
