California Incorporated City Boundaries

Complete accounting of all incorporated cities, including the boundary and name of each individual city. From 2009 to 2022 CAL FIRE maintained this 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 provide data directly. This data is then adjusted so it resembles the previous formats. Processing includes: • Clipping the dataset to traditional state boundaries • Erasing areas that span the Bay Area (derived from calw221.gdb) • Querying for incorporated areas only • Dissolving each incorporated polygon into a single feature • Calculating the COUNTY field to remove the word 'County' Version 25_2 is based on BOE_CityCounty_20250113, and includes all annexations present in BOE_CityAnx2023_20250113. Note: The Board of Equalization represents incorporated city boundaries as extending significantly into waterways, including beyond coastal boundaries.
