The Redistricting Process

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 underrepresented and non-English-speaking communities. The City of Costa Mesa is asking for your help to plan and draw new City districts.

The finalized maps that you will help us create will define the six City of Costa Mesa district borders, and these new districts will impact how you elect your Council Members 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?
