Coulterville, IL
Coulterville wildfire risk explained
Out of every US place USFS scores, Coulterville lands at the 10th percentile for wildfire risk to structures — among the lower wildfire-risk places nationally — a figure built from its 639 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Coulterville at the 9th percentile, close to its 10th-percentile risk score.
What "at risk" means for the buildings here
78.6% of Coulterville's 639 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 15.8% Direct and 5.6% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
How Coulterville compares
Compare Coulterville's two percentiles: 42nd within Illinois, only 10th nationally — a gap of 32 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Coulterville ranks 28,483 for wildfire risk (1 is highest) and 15,339 by building count (1 is largest). Within Illinois alone, it ranks 838 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
What this risk score means for insurance
At the 10th national percentile, Coulterville rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Lowering exposure, not just insuring around it
Coulterville's 78.6% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
Where Coulterville's figures come from
