About Fire Hazard Severity Zones

The dataset used in this online map was provided by CalFire

(Last Update: SRA 2024 and LRA 2025)

To enhance wildfire resiliency measures in California, Governor Gavin Newsom signed an executive order in February 2025 that fast-tracked the release of updated Fire Hazard Severity Zone mapping in local responsibility areas. These LRAs are areas protected by local fire districts, such as the Quincy Fire Department. The State Fire Marshal is mandated to classify lands within State Responsibility Areas into Fire Hazard Severity Zones (FHSZ). Fire Hazard Severity Zones fall into one of the following classifications:

• Moderate
• High
• Very High

The California laws that require Fire Hazard Severity Zones include California Public Resources Code 4201-4204, California Code of Regulations Title 14, Section 1280 and California Government Code 51175-89.

Materials and Construction Methods for Exterior Wildfire Exposure:

California's WUI building code (CBC Chapter 7A) apply to the design and construction of new buildings located in High and Very High FHSZs in Local Responsibility Areas. These materials and construction methods increase the ability of a building located in any Fire Hazard Severity Zone or any Wildland-Urban Interface Fire Area to resist the intrusion of flame or burning embers. Check with Plumas County's building department to determine which ignition resistant building codes apply to your project.

In addition, Government Code Section 51182 calls for defensible space clearance and other wildland fire safety practices for buildings. Owners are also required to make a natural hazard disclosure as part of a real estate transfer. For information regarding "home hardening" and defensible space clearance, visit www.ReadyForWildfire.org.

The Plumas County Building Department has adopted the latest cycle of the California Building Code which now requires the ASCE Hazard Tool (7-22) for building design criteria. To access this new tool, please click here: ASCE Hazard Tool

Be aware the snow load values are mapped to a 0.5 mile resolution which can create a mismatch between the mapped elevation and the site-specific elevation.

Consult the Building Department for locations where the reported "elevation" and the "mapped elevation" differ significantly.
