How exposed is Illinois City to wildfire?
USFS scores Illinois City at the 53rd national percentile for wildfire risk to structures (modestly above the national average for wildfire risk), a figure built from 130 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Illinois City's burn probability — fire likelihood with no building count factored in — sits at the 55th percentile nationally.
What "at risk" means for the buildings here
Of Illinois City's 130 counted buildings, 58.5% carry Direct exposure and only 0% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
