The CAL FIRE Office of the State Fire Marshal provides and maintains the Fire Hazard Severity Zones (FHSZ) Map to identify areas throughout California with varying levels of wildfire risk. 

The map assesses potential wildfire hazards based on factors like vegetation, topography, weather patterns, and historical fire activity.

About the Map:

• Risk Levels: The map classifies areas into three categories:
  • Moderate: Areas with a low-to-moderate risk of wildfire due to vegetation type and density.
  • High: Areas with conditions that increase the likelihood of wildfire spread.
  • Very High: Areas where wildfire behavior is expected to be extreme, posing the highest risk to life, property, and natural resources.

The map allows users to enter an address to determine the fire hazard severity for specific locations.
