Existing law requires the State Fire Marshal to identify areas of the state as moderate, high, and very high fire hazard severity zones based on specified criteria. Existing law requires the State Fire Marshal to periodically review the areas in the state identified as very high fire hazard severity zones, as specified. Existing law requires a local agency, within 30 days after receiving a transmittal from the State Fire Marshal that identifies those fire hazard severity zones, to make the information available for public review and comment, and to present the information in a format that is understandable and accessible to the general public, including, but not limited to, maps. Existing law requires a person who owns, leases, controls, operates, or maintains an occupied dwelling or structure in a very high fire hazard severity zone to take certain fire risk management measures, including maintaining defensible space of 100 feet from each side of the structure, except as provided. Existing law requires the Office of the State Fire Marshal to develop a model defensible space program, as provided, that includes, but is not limited to, specified components, including enforcement mechanisms for compliance with and maintenance of defensible space requirements. Existing law includes among these enforcement mechanisms, among other things, site inspections.
This bill would require the factors on which the fire severity zones are based to include areas within the perimeter of a wildfire that burned 1,000 or more acres, destroyed more than 10 structures, or resulted in a fatality, and to include areas at risk for an urban conflagration that accounts for the potential for structures to serve as a fuel source that extends the ember cast outside of wildland areas and areas where agricultural land affects fire hazard. The bill would require the State Fire Marshal to publish the model and methodology used to develop the fire hazard severity zones on its internet website at least 60 days before finalizing those designations and to publish the model and methodology for specified factors whenever the State Fire Marshal reviews the fire severity zones.
This bill would require the State Fire Marshal to designate any area that is within the perimeter of a wildfire described above occurring on or after January 1, 2025, as a post-wildfire safety area, as defined, and to transmit a map of the post-wildfire safety area to any local agency with jurisdiction over territory in the designated area within a specified timeframe. Within a certain timeframe following the transmission of the map by the State Fire Marshal, this bill would require the designation of a post-wildfire safety area to trigger the application of state fire protection standards, as defined, in the area. The bill would exempt any designation of a post-wildfire safety area by the State Fire Marshal from the rulemaking provisions of the Administrative Procedure Act. The bill would require a local agency to, within 10 business days of receiving the map, post a notice at the office of the county recorder, county assessor, and city or county planning agency identifying the location of the post-wildfire safety area, and to post the map on its internet website. By requiring local agencies to take specified actions regarding post-wildfire safety areas, this bill would impose a state-mandated local program.
The Planning and Zoning Law requires the legislative body of a city or county to adopt a comprehensive, long-term general plan that includes various elements, including, among others, a safety element for the protection of the community from specified risks. Existing law requires, upon the next revision of the housing element on or after January 1, 2014, the safety element to be reviewed and updated as necessary to address the risk of fire for land classified as state responsibility areas and land classified as very high fire hazard severity zones, as defined.
This bill would additionally require the safety element to be reviewed and updated as necessary to address the risk of fire for land classified as a post-wildfire safety area. By requiring local entities to take specified actions regarding the safety elements of their general plans, this bill would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
