Riverdale, NJ
How exposed is Riverdale to wildfire?
USFS's Wildfire Risk to Communities model puts Riverdale at the 33rd national percentile for risk to structures, close to the middle of USFS's national wildfire-risk range — a score built from 1,202 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 Riverdale at the 32nd percentile, close to its 33rd-percentile risk score.
Riverdale's building exposure, zone by zone
USFS puts 74.4% of Riverdale's 1,202 buildings in the Indirect exposure zone, versus 22.9% Direct and 2.8% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
Riverdale against the rest of the country
Riverdale scores 33rd nationally and 31st within New Jersey — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Riverdale ranks 21,150 for wildfire risk (1 is highest) and 10,641 by building count (1 is largest). Within New Jersey alone, it ranks 487 of 700 places by risk. See the full county-by-county picture for New Jersey on its state page.
What this risk score means for insurance
At the 33rd 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.
Hardening a home in Riverdale
Riverdale's 74.4% 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.
Where Riverdale's figures come from
Riverdale's 33rd-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 indirect exposure actually means, with real examples from across the dataset.
