How You Can Help Shape Sonoma County’s Future
Every 10 years, local governments use new data from the Census to redraw their district lines to reflect how local populations have changed. State law requires cities and counties to engage communities in the redistricting process by holding public hearings and doing public outreach, including to non-English-speaking communities. The County of Sonoma is asking for your help to plan, draw, and redivide new County districts.
The Board of Supervisors established the Sonoma County Advisory Redistricting Commission (ARC) at their February 23, 2021 meeting to advise and assist the Board with redrawing supervisorial district boundaries. The ARC has 19 members, comprised of two appointees per district and nine at-large members.
The finalized maps that you will help us create will define the five Sonoma County district borders, and these new County districts will impact how you elect your Sonoma County Supervisors for the next 10 years.
Our primary goal when developing election districts is to draw lines that respect neighborhoods, history and geographical elements. So we want to know: What do you consider the boundaries of your neighborhood?
Share your specific thoughts, draw a map or attend a public hearing to get involved!
