Donora, PA
Donora wildfire risk explained
Out of every US place USFS scores, Donora lands at the 31st percentile for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — a figure built from its 2,442 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Donora's burn probability — fire likelihood with no building count factored in — sits at the 32nd percentile nationally.
Where Donora's buildings actually sit
2,442 buildings are counted in Donora, and 92.8% of them are Indirect exposure — ember-driven risk rather than the 7.2% in Direct exposure or the 0% rated Minimal.
Where Donora ranks
Donora's risk sits at a similar level relative to Pennsylvania (41st percentile statewide) as it does nationally (31st) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Donora ranks 21,725 for wildfire risk (1 is highest) and 6,417 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,178 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Shopping for coverage in Donora
Donora's moderate rating (31st percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Lowering exposure, not just insuring around it
Because 92.8% of Donora's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
More on how this number was built
Donora's 31st-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Donora, see the exposure-zones guide.
