Public Input is a critical component of the County Supervisorial Redistricting process. The following provides an outline of the type of input.

Communities of Interest (COI)

State law defines a “community of interest” as “a population that shares common social or economic, geographic, or cultural 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 of interest across the County and to the extent practicable, to try to keep community of interest together in a district.

Through the Districtr mapping tool, you can make sure the County knows about your community by telling us what is important to you, drawing your community on a map, and submitting your community directly to the County. Learn more about Communities of Interest.

District Map Proposals

Every ten years, supervisorial districts must be redrawn so that each district is substantially equal in population. Members of the public may submit their own proposed redistricting plans or draft maps directly to the County. The input from the public will help the County develop its redistricting plans.
