Silvis, IL
How exposed is Silvis to wildfire?
USFS scores Silvis at the 32nd national percentile for wildfire risk to structures (close to the middle of USFS's national wildfire-risk range), a figure built from 3,827 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Silvis at the 33rd 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
Silvis rates 95% Minimal exposure against just 4.7% Direct and 0.3% Indirect — of 3,827 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually.
Where Silvis ranks
Compare Silvis's two percentiles: 83rd within Illinois, only 32nd nationally — a gap of 50 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Silvis ranks 21,423 for wildfire risk (1 is highest) and 4,400 by building count (1 is largest). Within Illinois alone, it ranks 256 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
Silvis's moderate rating (32nd percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
What would actually reduce this score
Even with 95% of Silvis 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
Silvis's 32nd-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 Silvis, see the exposure-zones guide.
