Truckee staff outline new state fire-hazard maps, adoption deadline and local mitigation programs

Town of Truckee staff described Thursday night how updated California Fire Hazard Severity Zone (FHSZ) maps will affect local regulations, timelines and mitigation programs, and answered residents' questions about insurance, code changes and financial assistance.

The town received CAL FIRE'recommended maps on Feb. 10 and made them available for public review on Feb. 25; staff said state rules require local agencies to (1) make the maps available for public comment within 30 days of transmittal, and (2) adopt local ordinances designating moderate, high and very high FHSZs within 120 days. That 120-day deadline puts Truckee's ordinance-adoption deadline at June 10, 2025. The town must then submit adopted maps and the ordinance to the Board of Forestry and Fire Protection within 30 days of adoption.

The town presentation began with background from CAL FIRE and the Office of the State Fire Marshal on the history and modeling behind the updated zones. "Fire hazard severity zone maps are built to describe relative wildland and urban interface fire hazard potential over the long term," said Jamie, a member of the CAL FIRE modeling team, describing the three classes used statewide: moderate, high and very high. Jamie said model inputs included long-term burn probability (1991'020), vegetation, slope and the worst 5% of fire-weather observations to represent extreme conditions.

Why it matters: The state maps are hazard assessments, not parcel-level risk evaluations, and they trigger local regulatory steps. Town staff emphasized that hazard maps do not account for mitigations such as recent fuel treatments or home hardening; those measures affect risk but not the hazard…
