Riverdale, IA
Riverdale, IA's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Riverdale at the 50th national percentile for risk to structures, modestly above the national average for wildfire risk — a score built from 349 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Riverdale's burn probability — fire likelihood with no building count factored in — sits at the 54th percentile nationally.
What "at risk" means for the buildings here
USFS classifies 78.8% of Riverdale's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 21.2% Direct and 0% Indirect — a landscape-level risk rather than a building-by-building one.
Riverdale against the rest of the country
Compare Riverdale's two percentiles: 69th within Iowa, only 50th nationally — a gap of 19 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Riverdale ranks 15,720 for wildfire risk (1 is highest) and 20,334 by building count (1 is largest). Within Iowa alone, it ranks 317 of 1,017 places by risk. See the full county-by-county picture for Iowa on its state page.
What this risk score means for insurance
Riverdale's elevated wildfire rating (50th percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
Lowering exposure, not just insuring around it
With 78.8% of buildings rated Minimal exposure, Riverdale gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
