Layer: Counties (ID:4)

View In: Map Viewer

Name: Counties

Display Field: COUNTY

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The original County GIS layer was created by dissolving the county and city boundary dataset created by the California State Board of Equalization to represent county boundaries that are inclusive of incorporated cities in May 2023. The source GIS layer is updated regularly and contains the boundaries of the unincorporated county and incorporated cities within the state of California based on statement of boundary change filings received by the Board of Equalization per Government Code 54900. The boundaries are aligned to the State Board of Equalization's tax rate area maps.Next, the layer was intersected with the GIS layer Wildfires_Dissolve using the intersect tool to create Wildfires_Dissolve_Intersect. Wildfires_Dissolve was created from the Wildfires GIS layer by using the dissolve tool to dissolve overlapping wildfire perimeters into combined polygons. After calculating the area in US Survey Acres for each feature in the Wildfires_Dissolve_Intersect layer, summary statistics were used to add up the total area affected by wildfires per county (with COUNTY being the summary field). The summary statistics were joined with the Counties layer in order to calculate the percentage of total county area impacted by wildfires. The percentage was saved in field WILDFIRE_Area_Percent and used to create graduated colors symbology for the Counties layer. Geoprocessing performed by Amelie Schaefer, 12/12/2024
