Riverdale, IL
How exposed is Riverdale to wildfire?
Riverdale sits at the 45th percentile nationally for wildfire risk to structures — modestly above the national average for wildfire risk — per USFS's Wildfire Risk to Communities model, built from its 5,169 counted buildings, not vegetation cover alone. (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 47th percentile nationally.
Where Riverdale's buildings actually sit
USFS classifies 99.7% of Riverdale's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 0.3% Direct and 0% Indirect — a landscape-level risk rather than a building-by-building one. At 5,169 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Riverdale compares
Compare Riverdale's two percentiles: 96th within Illinois, only 45th nationally — a gap of 51 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Riverdale ranks 17,356 for wildfire risk (1 is highest) and 3,334 by building count (1 is largest). Within Illinois alone, it ranks 58 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Shopping for coverage in Riverdale
At the 45th national percentile, Riverdale rates elevated for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
What would actually reduce this score
Even with 99.7% of Riverdale outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
