Local government can add additional VHFHSZs. CAL FIREs fire scientists and wildfire mitigation experts developed the map using a science based and field-tested model that assigns a hazard score based. Local government has 120 days to designate, by ordinance, very high fire hazard severity zones within its jurisdiction after receiving the recommendation. The process of finalizing these boundaries involved an extensive local review process, the details of which are available at (click on "Continue as guest without logging in"). This specific map is based on a geographic information system dataset that depicts final CAL FIRE recommendations for Very High FHSZs within the local jurisdiction. It is likely that the fire hazard severity zones will be used for updates to the safety element of general plans. The updated zones will also be used to identify property whose owners must comply with natural hazards disclosure requirements at time of property sale and 100 foot defensible space clearance. The updated very high fire hazard severity zones will be used by building officials for new building permits in LRA. These new codes include provisions to improve the ignition resistance of buildings, especially from firebrands. In late 2005 to be effective in 2008, the California Building Commission adopted California Building Code Chapter 7A requiring new buildings in VH FHSZs to use ignition resistant construction methods and materials. Local Responsibility Area VHFHSZ maps were initially developed in the mid-1990s and are now being updated based on improved science, mapping techniques, and data. Details on the project and specific modeling methodology can be found at. In December 2022, CAL FIRE began a public comment period for the regulatory adoption process to update the existing map that captures Fire Hazard Severity Zones (FHSZ), which is a comprehensive map that ranks California’s State Responsibility Area (SRA)or rural, unincorporated areasbased on the likelihood different areas will experience wildfire. Mapping of the areas, referred to as Very High Fire Hazard Severity Zones (VHFHSZ), is based on data and models of, potential fuels over a 30-50 year time horizon and their associated expected fire behavior, and expected burn probabilities to quantify the likelihood and nature of vegetation fire exposure (including firebrands) to buildings. Government Code 51175-89 directs the California Department of Forestry and Fire Protection (CAL FIRE) to identify areas of very high fire hazard severity zones within Local Responsibility Areas (LRA).
