Darien, IL

Darien, IL's wildfire risk, in USFS's own numbers

Moderate
39thpercentile nationally

USFS scores Darien at the 39th national percentile for wildfire risk to structures (close to the middle of USFS's national wildfire-risk range), a figure built from 7,098 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 Darien at the 40th percentile, close to its 39th-percentile risk score.

Where Darien's buildings actually sit

7,098Total buildings
2.1%Direct exposure
0%Indirect exposure
97.9%Minimal exposure

USFS classifies 97.9% of Darien's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 2.1% Direct and 0% Indirect — a landscape-level risk rather than a building-by-building one. At 7,098 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.

Where Darien ranks

Within Illinois, Darien ranks higher (91st percentile) than it does nationally (39th) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Darien ranks 19,339 for wildfire risk (1 is highest) and 2,416 by building count (1 is largest). Within Illinois alone, it ranks 131 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.

What this risk score means for insurance

At the 39th national percentile, Darien rates moderate for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.

Lowering exposure, not just insuring around it

With 97.9% of buildings rated Minimal exposure, Darien gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.

Where Darien's figures come from

Darien's 39th-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 Darien's dominant minimal exposure actually means, with real examples from across the dataset.
