Grand Marsh, WI
How exposed is Grand Marsh to wildfire?
USFS scores Grand Marsh at the 32nd national percentile for wildfire risk to structures (close to the middle of USFS's national wildfire-risk range), a figure built from 133 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 Grand Marsh at the 31st percentile, close to its 32nd-percentile risk score.
What "at risk" means for the buildings here
Most of Grand Marsh's buildings (51.9%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
How Grand Marsh compares
Within Wisconsin, Grand Marsh ranks higher (73rd percentile) than it does nationally (32nd) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Grand Marsh ranks 21,385 for wildfire risk (1 is highest) and 27,602 by building count (1 is largest). Within Wisconsin alone, it ranks 224 of 808 places by risk. See the full county-by-county picture for Wisconsin on its state page.
Grand Marsh and the insurance market
Grand Marsh's moderate rating (32nd percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Hardening a home in Grand Marsh
Grand Marsh's 51.9% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
More on how this number was built
Grand Marsh's 32nd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Grand Marsh, see the exposure-zones guide.
