Riverton, WY
Riverton wildfire risk explained
Out of every US place USFS scores, Riverton lands at the 66th percentile for wildfire risk to structures — well above the national norm for wildfire risk — a figure built from its 5,229 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Riverton at the 63rd national percentile — 3 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Riverton's buildings actually sit
Indirect exposure is dominant in Riverton (56% of 5,229 buildings): far enough from burnable vegetation to avoid flame contact, close enough for wind-blown embers. Only 8.8% sit in the Direct zone. At 5,229 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Riverton compares
Riverton's 66th national percentile looks worse in isolation than its 23rd ranking inside Wyoming does — this place is on the milder end for its own state, by 43 points. Among the 31,521 US communities USFS scores, Riverton ranks 10,702 for wildfire risk (1 is highest) and 3,298 by building count (1 is largest). Within Wyoming alone, it ranks 148 of 192 places by risk. See the full county-by-county picture for Wyoming on its state page.
What this risk score means for insurance
At the 66th percentile nationally, Riverton 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.
What would actually reduce this score
Riverton's 56% 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.
