CAL FIRE Fire Hazard Severity Zone Map Update

CAL FIRE Fire Hazard Severity Zone Map Update

CAL FIRE – Office of the State Fire Marshal is in the process of updating the state’s Fire Hazard Severity Zones for rural, unincorporated areas. The map of these zones identify the likelihood an area will experience wildfire.

CAL FIRE’s fire scientists and wildfire mitigation experts developed the map using a science-based and field-tested model that assigns a hazard score based on the factors that influence fire likelihood and fire behavior. The zones fall into three categories: moderate, high and very high.

The draft map and other information is available at
