Naperville, IL
How exposed is Naperville to wildfire?
Naperville's 42,276 buildings earn a 34th-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.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Naperville at the 31st percentile, close to its 34th-percentile risk score.
Naperville's building exposure, zone by zone
Naperville rates 95.2% Minimal exposure against just 2.9% Direct and 2% Indirect — of 42,276 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually. At 42,276 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Naperville ranks
Compare Naperville's two percentiles: 85th within Illinois, only 34th nationally — a gap of 51 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Naperville ranks 20,887 for wildfire risk (1 is highest) and 225 by building count (1 is largest). Within Illinois alone, it ranks 220 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Shopping for coverage in Naperville
At the 34th national percentile, Naperville rates moderate 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
With 95.2% of buildings rated Minimal exposure, Naperville gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
