Riverdale, VA
How exposed is Riverdale to wildfire?
Riverdale sits at the 38th percentile nationally for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — per USFS's Wildfire Risk to Communities model, built from its 882 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Riverdale at the 39th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Direct exposure dominates in Riverdale: 73.1% of its 882 buildings, versus 26.9% Indirect and 0% Minimal. Clearing space around a structure changes the outcome here more than any single building-material swap.
How Riverdale compares
There's little gap between Riverdale's 38th national percentile and its 28th percentile inside Virginia, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Riverdale ranks 19,714 for wildfire risk (1 is highest) and 12,891 by building count (1 is largest). Within Virginia alone, it ranks 489 of 681 places by risk. See the full county-by-county picture for Virginia on its state page.
Riverdale and the insurance market
At the 38th national percentile, Riverdale rates moderate for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Lowering exposure, not just insuring around it
Riverdale's 73.1% Direct-exposure share means lot clearing around the structure typically outweighs any single material upgrade here. The home-hardening guide ranks the options for a place shaped like this.
Where Riverdale's figures come from
Riverdale's 38th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Riverdale's dominant direct exposure actually means, with real examples from across the dataset.
