Area-Based Elections
Redistricting based on New Census Data

In November 2020, Central San transitioned from an at-large to an area-based election system which will be in effect for the 2022 election cycle. With the 2020 Census now complete, the District will review the boundaries and reshape the division map with the latest data as required and will hold a series of public hearings.

The purpose of the public hearing is to receive public input regarding the REDISTRICTING of Director Division map boundaries that were formed in the fall of 2020 that set a preliminary election boundary map and sequence. With the 2020 Census completed, the District will review the boundaries and reshape the map as required with the latest data.
