Grand Detour, IL
How exposed is Grand Detour to wildfire?
Grand Detour sits at the 22nd percentile nationally for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — per USFS's Wildfire Risk to Communities model, built from its 331 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Grand Detour's burn probability — fire likelihood with no building count factored in — sits at the 23rd percentile nationally.
What "at risk" means for the buildings here
Grand Detour rates 64.1% Minimal exposure against just 36% Direct and 0% Indirect — of 331 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually.
Where Grand Detour ranks
Within Illinois, Grand Detour ranks higher (66th percentile) than it does nationally (22nd) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Grand Detour ranks 24,477 for wildfire risk (1 is highest) and 20,788 by building count (1 is largest).

What this risk score means for insurance
Grand Detour's moderate rating (22nd percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Lowering exposure, not just insuring around it
Grand Detour's 64.1% Minimal-exposure share means structure-level hardening matters less here than it would elsewhere — still worth the low-cost basics, per the home-hardening guide.
