Grand River, IA
Grand River wildfire risk explained
USFS's Wildfire Risk to Communities model puts Grand River at the 72nd national percentile for risk to structures, well above the national norm for wildfire risk — a score built from 183 actual buildings. (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 River at the 74th percentile, close to its 72nd-percentile risk score.
Grand River's building exposure, zone by zone
67.2% of Grand River's 183 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 32.8% Direct and 0% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
How Grand River compares
Within Iowa, Grand River ranks higher (95th percentile) than it does nationally (72nd) — 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 River ranks 8,855 for wildfire risk (1 is highest) and 25,496 by building count (1 is largest). Within Iowa alone, it ranks 49 of 1,017 places by risk. See the full county-by-county picture for Iowa on its state page.
Grand River and the insurance market
At the 72nd percentile nationally, Grand River carries the 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
Because 67.2% of Grand River's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
