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 to 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 San Francisco Bay (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 22_1 is based on BOE_CityCounty_20220225, and includes all annexations present in BOE_CityAnx2022_20220225 and BOE_CityAnx2023_20220223.

Note: The Board of Equalization represents incorporated city boundaries as extending significantly into waterways, including beyond coastal boundaries. To see the representation in its original form please reference the datasets listed above.
