Supervisorial District Boundary Information

County of Plumas Redistricting Process

Every ten years, local governments use new census data to redraw their district lines to reflect how local populations have changed. Assembly Bill 849 (2019) requires cities and counties to engage communities in the redistricting process by holding public hearings and/or workshops and doing public health outreach, including to non-English-speaking communities. 

What is redistricting?

Every ten years, districts must be redrawn so that each district is substantially equal in population. This process, called redistricting, is important in ensuring that each board member represents about the same number of constituents. In Plumas, the Board of Supervisors is responsible for drawing supervisorial districts. Redistricting is done using U.S. Census data, which was released on August 12, 2021. For the County of Plumas, the redistricting process will be completed by December 7, 2021. 

Why does redistricting matter to me?

Redistricting determines which neighborhoods and communities are grouped into a district for the purpose of electing a board member. 

Community members are encouraged to provide information regarding their communities of interest. A community of interest can be a neighborhood, network, or group of people who have common interests in the community and would benefit from being grouped into a single district. Keeping communities of interest together is an important principle in redistricting.

What criteria will our Board of Supervisors use when drawing district lines?

To the extent, practicable, district lines will be adopted using the following criteria: (1) geographically contiguous districts (each supervisorial district should share a common border with the next), (2) the geographic integrity of local neighborhoods or communities shall be respected in a manner that minimizes its division, (3) geographical integrity of a city shall be respected in a manner that minimizes its division, (4) easily identifiable boundaries that follow natural or artificial barriers (rivers, streets, highways, rail lines, etc.) and (5) lines shall be drawn to encourage geographic compactness. In addition, boundaries shall not be drawn for purposes of favoring or discriminating against a political party. 

How will our Board of Supervisors notify the public about redistricting?

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. 

The Board of Supervisors will notify the public about redistricting hearings, post maps online before adoption, and create a dedicated web page for all relevant information about the redistricting process. 

How can I get involved?

The Board of Supervisors will be holding public hearings to receive public input on where district lines should be drawn. Below is a timeline of the redistricting process and the dates public hearings will be held:


During the public hearings, you can submit public comments. In addition, you can submit public comments, including draft maps, via email to through November.
