San Francisco Bay Region Jurisdictions (Incorporated Places and Unincorporated County Lands)

The San Francisco Bay Region Jurisdictions feature set was developed by the Metropolitan Transportation Commission so tables containing values for both incorporated and unincorporated areas could be joined to a spatial feature set for mapping and analysis. County-level, 2020 TIGER/Line shapefiles, current as of May 28, 2021, were used to develop this feature set. Incorporated places (cities and towns) were erased from the county shapefile for the region. The remaining county areas (unincorporated lands) were then added to the incorporated places to produce a full, incorporated-unincorporated feature set for the region. For the final processing step, major water features were clipped from the jurisdiction feature set so only land areas remained.
