Jurisdictions

Complete accounting of all incorporated cities and unincorporated county areas, including the boundary and name of each individual jurisdictions. From 2009 to 2022 CAL FIRE maintained an incorporated city dataset by processing and digitally capturing annexations sent by the state Board of Equalization (BOE). In 2022 CAL FIRE began sourcing data directly from BOE in order to allow the authoritative department to provide data directly. This data is then adjusted so it resembles the previous formats. Processing includes: Clipping the dataset to traditional state boundaries Dissolving each polygon into a single feature Calculating the County field to remove the word 'County' Calculating the Jurisdiction field for unincorporated areas to include the county name and and '(Unincorporated)' Adding and calculating a field to denote jurisdiction type Other aspects of the dataset, including overlapping topology and misalignment with county parcels, are generally accepted 'as-is,' and minimal effort has been made to correct them. Version 26_1 is based on BOE_CityCounty_20260330, and includes all annexations present in BOE_CityAnx2026_20260330. Note: The Board of Equalization represents jurisdictional boundaries as extending significantly into waterways, including beyond coastal boundaries. To see the representation in its original form please reference the datasets listed above.
