Boulder Hill, IL
Boulder Hill, IL's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Boulder Hill at the 10th national percentile for risk to structures, among the lower wildfire-risk places nationally — a score built from 3,122 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Boulder Hill's burn probability — fire likelihood with no building count factored in — sits at the 11th percentile nationally.
Boulder Hill's building exposure, zone by zone
Only 0.5% of Boulder Hill's 3,122 buildings carry Direct exposure and 0% carry Indirect; the remaining 99.6% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure.
Boulder Hill against the rest of the country
Compare Boulder Hill's two percentiles: 42nd within Illinois, only 10th nationally — a gap of 32 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Boulder Hill ranks 28,513 for wildfire risk (1 is highest) and 5,261 by building count (1 is largest). Within Illinois alone, it ranks 842 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Boulder Hill and the insurance market
At the 10th national percentile, Boulder Hill rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
What would actually reduce this score
Even with 99.6% of Boulder Hill 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 Boulder Hill's figures come from
Boulder Hill's 10th-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 Boulder Hill's dominant minimal exposure actually means, with real examples from across the dataset.
