River Sioux, IA
River Sioux, IA's wildfire risk, in USFS's own numbers
USFS scores River Sioux at the 76th national percentile for wildfire risk to structures (well above the national norm for wildfire risk), a figure built from 66 real buildings rather than raw vegetation cover. (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 Sioux at the 71st percentile, close to its 76th-percentile risk score.
River Sioux's building exposure, zone by zone
Most of River Sioux's buildings (86.4% of 66) 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.
Where River Sioux ranks
Compare River Sioux's two percentiles: 98th within Iowa, only 76th nationally — a gap of 22 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, River Sioux ranks 7,628 for wildfire risk (1 is highest) and 30,418 by building count (1 is largest). Within Iowa alone, it ranks 19 of 1,017 places by risk. See the full county-by-county picture for Iowa on its state page.
Shopping for coverage in River Sioux
River Sioux's high rating (76th 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
With 86.4% of buildings rated Minimal exposure, River Sioux gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
