Williamson, IL
Williamson, IL's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Williamson at the 11th national percentile for risk to structures, among the lower wildfire-risk places nationally — a score built from 186 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Williamson at the 11th national percentile — 0 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
Most of Williamson's buildings (64% of 186) fall outside USFS's Direct and Indirect zones entirely — that doesn't zero out the score above, it means the risk is regional, not structure-by-structure.
Williamson against the rest of the country
Williamson's 44th-percentile standing inside Illinois outpaces its 11th national percentile — this is a hotter spot than most of its own state, even though the state as a whole runs cooler nationally. Among the 31,521 US communities USFS scores, Williamson ranks 28,198 for wildfire risk (1 is highest) and 25,384 by building count (1 is largest). Within Illinois alone, it ranks 806 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
Williamson's low wildfire rating (11th percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
What would actually reduce this score
Even with 64% of Williamson outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
Where Williamson's figures come from
Williamson's 11th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Williamson's dominant minimal exposure actually means, with real examples from across the dataset.
