Lewis, WI
Lewis wildfire risk explained
USFS scores Lewis at the 41st national percentile for wildfire risk to structures (modestly above the national average for wildfire risk), a figure built from 171 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 Lewis at the 42nd percentile, close to its 41st-percentile risk score.
Where Lewis's buildings actually sit
59.7% of Lewis's 171 buildings sit in USFS's Direct exposure zone, roughly 102 structures close enough to burnable vegetation for flame contact, not just embers — 40.4% fall in the Indirect, ember-only zone and 0% are Minimal.
Where Lewis ranks
Within Wisconsin, Lewis ranks higher (92nd percentile) than it does nationally (41st) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Lewis ranks 18,645 for wildfire risk (1 is highest) and 26,007 by building count (1 is largest). Within Wisconsin alone, it ranks 64 of 808 places by risk. See the full county-by-county picture for Wisconsin on its state page.
Lewis and the insurance market
Lewis's elevated rating (41st percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Lowering exposure, not just insuring around it
Lewis's 59.7% Direct-exposure share means lot clearing around the structure typically outweighs any single material upgrade here. The home-hardening guide ranks the options for a place shaped like this.
Where Lewis's figures come from
Every one of the two percentiles behind Lewis's 18,645-place national rank traces to USFS's Wildfire Risk to Communities dataset — see the methodology guide. The exposure-zones guide covers what Lewis's dominant direct exposure actually means, with real examples from across the dataset.
