Bourbonnais, IL
Bourbonnais, IL's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Bourbonnais at the 8th national percentile for risk to structures, among the lower wildfire-risk places nationally — a score built from 6,162 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Bourbonnais at the 10th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Only 2.7% of Bourbonnais's 6,162 buildings carry Direct exposure and 0% carry Indirect; the remaining 97.3% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure. At 6,162 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Bourbonnais ranks
Compare Bourbonnais's two percentiles: 39th within Illinois, only 8th nationally — a gap of 31 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Bourbonnais ranks 28,860 for wildfire risk (1 is highest) and 2,813 by building count (1 is largest). Within Illinois alone, it ranks 882 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
Bourbonnais's low rating (8th 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
Bourbonnais's 97.3% 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.
