Description: Fire Hazard Severity Zone classes from the map dated February 24, 2025.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 is being phased by regional areas of the state. This data set represents Phase 2 or the process, and includes the following counties:[Alameda, Contra Costa, Del Norte, Humboldt, Marin, Mendocino, Merced, Napa, San Francisco, San Joaquin, San Mateo, Santa Clara, Santa Cruz, Solano, Sonoma, Stanislaus, Yolo] Details on the planned schedule and an index to all phase areas can be found at website: https://fire-hazard-severity-zones-rollout-calfire-forestry.hub.arcgis.com/pages/access-mapData was clipped to Solano County Boundaries by Solano DoIT GIS team.Per Solano County Board of Supervisors ordinance 2025-1862 effective July 4, 2025 this layer reflects the reviewed and accepted recommendations by the Office of the State Fire Marshal (OSFM) based on 2025 updates to the same.Created by Solano DoIT GIS Team 06/10/2025
