Grafton, WI
How exposed is Grafton to wildfire?
Grafton's 4,350 buildings earn a 23rd-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.)
Fire likelihood alone (USFS's burn-probability figure) ranks Grafton at the 24th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
Grafton's building exposure, zone by zone
Most of Grafton's buildings (91.6% of 4,350) fall outside USFS's Direct and Indirect zones entirely — that doesn't zero out the score above, it means the risk is regional, not structure-by-structure.
Grafton against the rest of the country
Within Wisconsin, Grafton ranks higher (43rd percentile) than it does nationally (23rd) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Grafton ranks 24,221 for wildfire risk (1 is highest) and 3,934 by building count (1 is largest). Within Wisconsin alone, it ranks 462 of 808 places by risk. See the full county-by-county picture for Wisconsin on its state page.
Grafton and the insurance market
Grafton's moderate wildfire rating (23rd percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
Hardening a home in Grafton
Even with 91.6% of Grafton 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 Grafton's figures come from
Grafton's 23rd-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 Grafton's dominant minimal exposure actually means, with real examples from across the dataset.
