FHSZ Map Timeline

The establishment of Local Response Area (LRA) Fire Hazard Severity Zones (FHSZ) was a result of the 1991 Oakland Hills Fire. The map was revised in 2007 and again in 2024, with its release on February 24, 2025 in accordance with Government Code 51178. In the current version the LRA is broken down into 3 categories: Moderate, High, and Very High.  The creation of the current map is based on new science, ember spread and local climate data.  The modeling looks at the probability of an area burning and expected fire behavior under extreme fuel and weather conditions to identify the “Hazard” level in each geographical area.

The City of Livermore and the City of Pleasanton are required under Government Code 51178.5 to make the maps available for public review and comment, and shall designate by ordinance their respective Moderate, High, and Very High Fire Hazard Severity Zones within 120 days of receiving the State Fire Marshal recommendations per Government Code 51179.

The LPFD FHSZ Map provides an interactive experience.  Search properties within the City of Livermore and the City of Pleasanton by Assessor's Parcel Number (APN) or Property Address to determine a property's fire hazard zone.
