Fire Hazard Severity Zones

CAL FIRE’s office of the State Fire Marshal is hard at work updating the Fire Hazard Severity Zones for rural, unincorporated areas all across our expansive state. The map of these zones identifies the likelihood an area will experience wildfire events.

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 factors that influence fire likelihood and fire behavior. The zones fall into three categories: moderate, high, and very high.

The evolving draft map and more relevant information is available here. The public comment period closed on August 9, 2023. At this time, CAL FIRE Office of the State Fire Marshal is reviewing all comments received during the public comment period. For further information regarding the adoption process, please visit the OSFM FHSZ Maps page.
