Fire Hazard Severity Zones

Fire Hazard Severity Zone (FHSZ) maps are created by the California Department of Forestry and Fire Protection (Cal Fire) to identify areas where a wildfire is more likely to occur. Scientific models are used to geographically identify FHSZ's through an analysis of factors, such as:

  • Predominant vegetation type (vegetation is the fuel for a wildfire)
  • Terrain (severity of slopes)
  • Fire history (past fires are good predictors of future fires)
  • Weather patterns (high winds, low humidity, and high temperatures contribute to fire severity)

The maps are updated periodically and are available for viewing.
