Wilsonville, IL
Wilsonville wildfire risk explained
USFS scores Wilsonville at the 17th national percentile for wildfire risk to structures (among the lower wildfire-risk places nationally), a figure built from 389 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Wilsonville's burn probability — fire likelihood with no building count factored in — sits at the 18th percentile nationally.
What "at risk" means for the buildings here
Most of Wilsonville's buildings (78.7%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.

Shopping for coverage in Wilsonville
Wilsonville's low wildfire rating (17th 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.
Hardening a home in Wilsonville
With ember exposure the dominant pattern in Wilsonville (78.7% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
Where Wilsonville's figures come from
Wilsonville's 17th-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 Wilsonville's dominant indirect exposure actually means, with real examples from across the dataset.
