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 outreach, including to non English-speaking communities. 


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 city council member represents about the same number of constituents. As required by State Laws, the Chino Hills City Council is responsible for adopting Chino Hills council districts. Redistricting is completed using U.S. Census data, which is released around October 2021. For the City of Chino Hills, the redistricting process must be completed by April 17, 2022. 

Why does redistricting matter to me?

Redistricting determines which neighborhoods and communities are grouped together into a district for the purposes of electing a council member.

The City Council will seek input in selecting the next district map for our City Council. You have an opportunity to share with the City Council how you think district boundaries should be drawn to best represent your community.

You can contact the City Clerk at (909) 364-2624 to find out more about how the process works. 

What do the existing council districts look like?

Residents can look up their current district by using an interactive map online.  Please follow these directions:

  • Single-Family Homes: enter street address in search box.
  • Condominiums: enter street address in search box.
  • Apartment Homes: type “apartment” in the search box for a list of apartment complexes (scroll through list).
  • Mobile Homes: type “mobile home” in the search box for a list of mobile home parks (scroll through list).

What criteria will our City Council use when drawing district lines? 

To the extent practicable, district lines will be adopted using the following criteria: (1) geographically contiguous districts (each City Council 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) geographic 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 City Council notify the public about redistricting? 

The City Council 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. Translators will be provided for Public Hearings if residents submit a request 72 hours in advance. The community will be notified about redistricting Public Hearing dates and the City will post maps online before adoption. This dedicated web page will be kept up to date for all relevant information about the redistricting process.
