Lisle, IL
Lisle wildfire risk explained
Lisle's 6,377 buildings earn a 30th-percentile wildfire-risk score nationally under USFS's model — close to the middle of USFS's national wildfire-risk range. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Lisle at the 31st 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
91.9% of Lisle's 6,377 buildings sit in USFS's Minimal exposure zone, with only 4.3% rated Direct — risk here comes from regional burn probability more than proximity to burnable vegetation at the structure itself. At 6,377 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Lisle against the rest of the country
Compare Lisle's two percentiles: 80th within Illinois, only 30th nationally — a gap of 50 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Lisle ranks 22,084 for wildfire risk (1 is highest) and 2,716 by building count (1 is largest). Within Illinois alone, it ranks 296 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Shopping for coverage in Lisle
Lisle's moderate rating (30th 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
With 91.9% of buildings rated Minimal exposure, Lisle gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
