Clinton County's mean annual burn probability is at or above 4% of U.S. counties (national percentile rank, USDA Forest Service, Wildfire Risk to Communities).

It is a county figure, not a forecast for any one home. About 59% of the county's buildings sit in the minimal-exposure zone, where the chance is lower.
No Wildland-Urban Interface class is published for Clinton County in our dataset, so none is shown. Homes in WUI areas face elevated wildfire exposure due to proximity to fire-prone vegetation.

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.
