River Heights, UT
How exposed is River Heights to wildfire?
USFS's Wildfire Risk to Communities model puts River Heights at the 90th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 776 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 River Heights at the 86th percentile, close to its 90th-percentile risk score.
River Heights's building exposure, zone by zone
776 buildings are counted in River Heights, and 77.8% of them are Indirect exposure — ember-driven risk rather than the 18.4% in Direct exposure or the 3.7% rated Minimal.
How River Heights compares
River Heights's 90th national percentile looks worse in isolation than its 55th ranking inside Utah does — this place is on the milder end for its own state, by 35 points. Among the 31,521 US communities USFS scores, River Heights ranks 3,164 for wildfire risk (1 is highest) and 13,860 by building count (1 is largest). Within Utah alone, it ranks 148 of 326 places by risk. See the full county-by-county picture for Utah on its state page.
River Heights and the insurance market
River Heights's very high rating (90th percentile) puts it among the places where the national carrier-pullback trend is most relevant — not a guarantee of a coverage problem, but a reason to shop rather than assume.
Lowering exposure, not just insuring around it
River Heights's 77.8% 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
River Heights's 90th-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 River Heights, see the exposure-zones guide.
