Service Description: Under the purpose of fire safety and prevention, and by statutory authority, The State Fire Marshal shall classify lands within Local Responsibility Areas (LRA) into fire hazard severity zones. Each zone shall embrace relatively homogeneous lands and shall be based on fuel loading, slope, fire weather, and other relevant factors present, including areas where winds have been identified by the department as a major cause of wildfire spread.
The California laws and regulations associated with Fire Hazard Severity Zones in LRA are found in California Government Code 51175-51189, and describe the objectives and and processes by which these data are developed, transmitted as a recommendation to local government agencies, and the subsequent required local ordinance adoption and documentation processes to see the zones finalized.
Delivery of Recommended LRA FHSZ data and maps was phased by 4 regional areas of the state. This data set represents all 4 phases combined into one dataset
