Data Sources & Methodology
Burn probability and the national percentile ranks come from the USFS Wildfire Risk to Communities (WRC) county summary, 2026 release (doi.org/10.2737/RDS-2024-0030). Fire hazard severity zones are from CalFire FRAP. Insurance discount estimates follow the California Department of Insurance Safer from Wildfires framework. Hardening cost estimates are reference ranges informed by IBHS guidance with a regional cost multiplier; they are estimates, not contractor quotes. Financial projections use a discount rate based on the 10-year Treasury yield and an insurance price inflation assumption; each paid answer reports the exact rates it used. All calculations are deterministic with no AI-generated content.
