Grantsville, UT
Grantsville wildfire risk explained
USFS's Wildfire Risk to Communities model puts Grantsville at the 98th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 4,901 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Grantsville at the 98th national percentile — 0 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Indirect exposure is dominant in Grantsville (67.1% of 4,901 buildings): far enough from burnable vegetation to avoid flame contact, close enough for wind-blown embers. Only 32.8% sit in the Direct zone.
How Grantsville compares
There's little gap between Grantsville's 98th national percentile and its 95th percentile inside Utah, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Grantsville ranks 645 for wildfire risk (1 is highest) and 3,492 by building count (1 is largest). Within Utah alone, it ranks 19 of 326 places by risk. See the full county-by-county picture for Utah on its state page.
Grantsville and the insurance market
At the 98th percentile nationally, Grantsville carries the very high rating that has pushed some carriers to limit new business in similarly-scored places elsewhere in the country. Worth comparing quotes rather than assuming last year's renewal terms still apply.
Lowering exposure, not just insuring around it
Grantsville's 67.1% 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.
