Sullivan, IL
Sullivan, IL's wildfire risk, in USFS's own numbers
USFS scores Sullivan at the 5th national percentile for wildfire risk to structures (among the lower wildfire-risk places nationally), a figure built from 2,524 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Sullivan at the 5th percentile, close to its 5th-percentile risk score.
Where Sullivan's buildings actually sit
Only 3.5% of Sullivan's 2,524 buildings carry Direct exposure and 0% carry Indirect; the remaining 96.5% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure.
How Sullivan compares
Sullivan's 27th-percentile standing inside Illinois outpaces its 5th 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, Sullivan ranks 30,034 for wildfire risk (1 is highest) and 6,258 by building count (1 is largest). Within Illinois alone, it ranks 1,058 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
Sullivan's low wildfire rating (5th 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 96.5% of Sullivan 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.
More on how this number was built
Sullivan's 5th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what minimal exposure implies beyond Sullivan, see the exposure-zones guide.
