Redistricting after the 2020 Census

Redistricting began in the later half of 2021, due to a delay in the release of the 2020 Census data. Because of the delay, redistricting has been occurring under different timelines. Precincts for the May 2022 Primary will be available Feb/Mar 2022. Special District zones for the Nov 2022 and May 2023 Election will be available in calendar year 2022.
