The regulation can be found in Title 14 of the California Code of Regulations (CCR) section 1280.01 and entitled “Fire Hazard Severity Zones in the SRA”. Therefore, the fire hazard severity zone designations and accompanying maps must follow the Administrative Procedures Act (APA) and be approved by the Office of Administrative Law (OAL). Classification of all lands within State Responsibility Areas into fire hazard severity zones is required by law.Use the interactive viewer to compare where FHSZ has changed in SRA.

Fire Hazard Severity Zones viewer in State Responsibility Area “Risk” is the potential damage a fire can do to the area under existing conditions, accounting for any modifications such as fuel reduction projects, defensible space, and ignition resistant building construction. “Hazard” is based on the physical conditions that create a likelihood and expected fire behavior over a 30 to 50-year period without considering mitigation measures such as home hardening, recent wildfire, or fuel reduction efforts. They are like flood zone maps, where lands are described in terms of the probability level of a particular area being inundated by floodwaters, and not specifically prescriptive of impacts. Wildfires can be caused by human activities (such as arson or campfires) or by natural events such as lightning. There are three levels of hazard in the State Responsibility Areas: moderate, high, and very high.įire Hazard Severity Zone maps evaluate “hazard,” not “risk”. A wildfire is any uncontrolled fire occurring on undeveloped land that requires fire suppression. Many factors are considered such as fire history, existing and potential fuel (natural vegetation), predicted flame length, blowing embers, terrain, and typical fire weather for the area. The Fire Hazard Severity Zone (FHSZ) maps are developed using a science-based and field-tested model that assigns a hazard score based on the factors that influence fire likelihood and fire behavior.
