Redistricting is the regular process of adjusting the lines of voting districts in accordance with population shifts. In California, public agencies and other organizations must redivide (or redraw) the lines of their districts every ten years once the results of the Census are released so that each district is substantially equal in population. This ensures that each elected official represents about the same number of constituents.
All district lines must be reviewed to meet strict requirements for population equality, voting rights protections, and in accordance with the California FAIR MAPS Act.
Redistricting determines which neighborhoods and communities are grouped together into a district for purposes of electing Supervisors. The Board of Supervisors will seek input in selecting the next district map for electing Supervisors. You have an opportunity to share with the Supervisorial District Lines Advisory Commission how you think district boundaries should be drawn to best represent your community either during the public hearings or by submitting comments to firstname.lastname@example.org.

The Board of Supervisors will reach out to local media to publicize the redistricting process. Also, we will make a good faith effort to notify community groups of various kinds about the redistricting process. Our public hearings and workshops will be provided in applicable languages if residents submit a request in advance to email@example.com.
The Board of Supervisors will notify the public about redistricting hearings and workshops, post maps online before adoption, and maintain this dedicated web page for all relevant information about the redistricting process.

No, you do not need to submit a fully completed map. You can draw boundaries for only your neighborhood or only a portion of the county. It is helpful if you submit written commentary with your map describing why the particular neighborhood or area should be kept together in a single district.
Yes, you may submit more than one map. Please draw as many maps as you like.
After you submit your map, the demographic consultants will generate the population and other demographic details for your proposed map. Maps can be viewed on the Draft Maps page or on the Interactive Review Map.
Once submitted, maps are considered public records.
