Draw a Map for 2021 Redistricting Project
Return to 2021 Redistricting Project
Redistricting is different from most issues that come up in County government. Instead of being limited to saying you support or oppose a County-prepared ordinance or resolution, you can draw a map yourself!
There are different tools for different purposes, and different tools for different levels of technical skill and interest.

Mapping Tools Overview
How to Submit your Map
Maps should be submitted to redistricting2021@sonoma-county.org. 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.
It is helpful if you submit written comments with your map describing how your map was drawn to meet the required criteria. An example of this would be describing the specific neighborhoods or communities of interest that are kept within a single district.
Once the Advisory Redistricting Commission and Board of Supervisors have gone through the process to hear your thoughts and see your drawn maps, they will post drafted maps here for your consideration.
Important: Please share your feedback on draft maps at any of the upcoming public meetings on redistricting or submit written feedback to redistricting2021@sonoma-county.org
