Willowbrook (Will), IL
How exposed is Willowbrook (Will) to wildfire?
USFS scores Willowbrook (Will) at the 59th national percentile for wildfire risk to structures (modestly above the national average for wildfire risk), a figure built from 645 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Willowbrook (Will) at the 62nd percentile, close to its 59th-percentile risk score.
Where Willowbrook (Will)'s buildings actually sit
72.1% of Willowbrook (Will)'s 645 buildings sit in USFS's Minimal exposure zone, with only 27.9% rated Direct — risk here comes from regional burn probability more than proximity to burnable vegetation at the structure itself.
How Willowbrook (Will) compares
Compare Willowbrook (Will)'s two percentiles: 100th within Illinois, only 59th nationally — a gap of 41 points that marks it as unusually exposed for its own state.

What this risk score means for insurance
At the 59th national percentile, Willowbrook (Will) rates elevated 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 72.1% of Willowbrook (Will) 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 Willowbrook (Will)'s figures come from
Willowbrook (Will)'s 59th-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 Willowbrook (Will)'s dominant minimal exposure actually means, with real examples from across the dataset.
