Five (5) Supervisoral Districts of San Diego County

Redistricting takes place every 10 years after the federal census. District boundaries for federal, state and local elected offices are redrawn to reflect new population data and shifting populations. The County’s district boundaries will change so the five County supervisors elected to represent those districts each serve about 650,000 residents and reflects the County’s diverse population. Fourteen people were selected for the County's IRC. The process will act independently from the influence of the Board of Supervisors and reasonably represent the County’s diversity.

On January 12, 2022, the IRC approved technical changes to the 2021 Redistricting Plan and Final Report adjusting boundaries of the supervisorial districts of the County of San Diego Board of Supervisors(https://www.sandiegocounty.gov/content/sdc/redistricting/2021-redistricting-plan-map1.html)

The Board adopted the redistricting ordinance on December 14, 2021 (https://www.sandiegocounty.gov/content/dam/sdc/redistricting/docs/ircmeetings/irc-meeting-12-14-21/Item%2005%20-%20Resolution%20Adopting%20Final%20Report%20re-%20Final%20Redistricting%20Plan%20-%20SIGNED.pdf)

The dataset was geoprocessed using SDE.JUR_COUNTY as the input and added to with the BOS districts from SDEP Atlantic. The input dataset was verified as having the correct features from the 1/12/2022 IRC District update. The geoprocessing function was IDENTITY using the JUR_COUNTY as the IDENTITY layer used to cut the DIST_SUPERVSIOR dataset. All data was downloaded to process in local FBGDB. The full size of the incorrect land area IRC dataset is 4525.8 sq. miles in area. This was reduced down 264.8 sq. miles to the true and correct county boundary size of 4261 sq. miles for the County of San Diego. This size removed the ocean areas (mentioned below). As discussed in the summary, there were at least 511 acres of land area incorrectly attributed to either no BOS District area or for having overlaps into surrounding Counties and Countries (Mexico). These errors all resulted from where the US Census data used in the BOS IRC linework was not in agreement with JUR_COUNTY (being on either side of any line in JUR_COUNTY is an error). All were corrected back to the be within and match exactly the County boundary and the actual vector line work (100% match). Interior linework or linework separating the boundaries between BOS districts 1-5 were not altered in anyway. Preserving these vectors preserves the spirit and intention of the IRC committee work to its original state. Areas in the ocean were removed from the BOS coastal district data as they confused the land use and land ownership values and distribution of area that is associated with the BOS districts. These ocean areas and all the original IRC linework are preserved with 100% fidelity in the DIST_SUPERVISOR SDE dataset at SanGIS.
