Rock City, IL
Rock City, IL's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Rock City lands at the 7th percentile for wildfire risk to structures — among the lower wildfire-risk places nationally — a figure built from its 194 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Rock City at the 7th percentile, close to its 7th-percentile risk score.
Rock City's building exposure, zone by zone
Only 18.6% of Rock City's 194 buildings carry Direct exposure and 0% carry Indirect; the remaining 81.4% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure.
Where Rock City ranks
Rock City's 36th-percentile standing inside Illinois outpaces its 7th 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, Rock City ranks 29,181 for wildfire risk (1 is highest) and 25,067 by building count (1 is largest). Within Illinois alone, it ranks 926 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Rock City and the insurance market
Rock City's low rating (7th 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
Rock City's 81.4% Minimal-exposure share means structure-level hardening matters less here than it would elsewhere — still worth the low-cost basics, per the home-hardening guide.
More on how this number was built
Rock City's 7th-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 Rock City, see the exposure-zones guide.
