Description: Fire Hazard Severity Zone (FHSZ) classifications and map, as mandated by California law and implemented by the State Fire Marshal. The latest FHSZ map, issued on September 29, 2023, was formally adopted on January 31, 2024, and became effective on April 1, 2024. It delineates lands within state responsibility areas into three fire hazard levels: moderate, high, and very high. These designations are determined based on an array of factors such as fuel loading, slope, fire weather, and wind patterns that contribute to wildfire spread.Developed through a science-based model, the FHSZ assessments consider fire history, potential fuel sources, predicted fire behavior, terrain, and typical fire weather conditions, aiming for a predictive outlook over 30 to 50 years. Unlike risk evaluations, these hazard classifications do not account for mitigative actions like home hardening, wildfire history, or fuel reduction efforts but focus on inherent physical conditions that influence fire likelihood and potential intensity.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. 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).Regulatory adherence mandates that this classification system and its accompanying maps follow the procedures set by the Administrative Procedures Act, transitioning from Title 14, Section 1280.01 to Title 19, Section 2201 of the California Code of Regulations. This shift signifies an administrative update without altering the geographic portrayal of FHSZs. The updated regulations are integral to enhancing wildfire preparedness and mitigation strategies across California, rooted in rigorous evaluation and a comprehensive understanding of fire behavior and hazards.Fields:sra - SRA: Classifications for State Responsibility Area (SRA)fhsz - FHSZ: Classifications from Moderate, High, Very High fhsz_description - FHSZ_Description matching classification as 1, 2, 3Data Uploaded 4/15/2024, DMachado, Solano County Department of Information Technology
