Description: Data as-is from SRA August 2024LRA Recommended November 2007 - December 2008 - February 2025FRA Adopted 2008California Fire Hazard Severity Zones (FHSZ), including both proposed Fire Hazard Severity Zones for State Responsibility Area lands and draft Very High Fire Hazard Severity Zones for Local Responsibility Area lands. Hosted on CAL FIRE Portal. SRA FHSZ adopted April 1, 2024A Fire Hazard Severity Zone (FHSZ) is a mapped area that designates zones (based on factors such as fuel, slope, and fire weather) with varying degrees of fire hazard (i.e., moderate, high, and very high). FHSZ maps evaluate wildfire hazards, which are physical conditions that create a likelihood that an area will burn over a 30- to 50-year period. They do not take into account modifications such as fuel reduction efforts.While FHSZs do not predict when or where a wildfire will occur, they do identify areas where wildfire hazards could be more severe and therefore are of greater concern. FHSZs are meant to help limit wildfire damage to structures through planning, prevention, and mitigation activities/requirements that reduce risk. The FHSZs serve several purposes: they are used to designate areas where California’s wildland urban interface building codes apply to new buildings; they can be a factor in real estate disclosure; and local governments consider fire hazard severity in the safety elements of their general plans.This service includes proposed Fire Hazard Severity Zones for State Responsibility Area lands and separate draft Very High Fire Hazard Severity Zones for Local Responsibility Area lands. Moderate, high, and very high FHSZs are found in areas where the State has financial responsibility for fire protection and prevention (SRA). Only very high FHSZs are found in Local Responsibility Areas (LRAs).This service represents the latest release of FHSZ. It will be updated when a new version is released. as of April 2024.PRC 4201 - 4204 and Govt. Code 51175-89 direct the California Department of Forestry and Fire Protection (CAL FIRE) to map areas of significant fire hazards based on fuels, terrain, weather, and other relevant factors. These zones, referred to as Fire Hazard Severity Zones (FHSZ), define the application of various mitigation strategies to reduce risk associated with wildland fires. CAL FIRE is remapping Fire Hazard Severity Zones (FHSZ) for State Responsibility Areas (SRA) and Very High Fire Hazard Severity Zones (VHFHSZ) in Local Responsibility Areas (LRA) to provide updated map zones, based on new data, science, and technology.
This specific dataset provides DRAFT boundaries for Very High FHSZs within LRA lands. Since these zones were the result of a model that considers influence of fire behavior and embers from adjacent lands, zones for SRA and FRA lands are included to assist in understanding the hazard zoning on LRA lands.
