Sewickley, PA
Sewickley, PA's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Sewickley lands at the 32nd percentile for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — a figure built from its 1,698 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Sewickley's burn probability — fire likelihood with no building count factored in — sits at the 32nd percentile nationally.
Where Sewickley's buildings actually sit
Indirect exposure is dominant in Sewickley (90.8% of 1,698 buildings): far enough from burnable vegetation to avoid flame contact, close enough for wind-blown embers. Only 9.2% sit in the Direct zone.
Where Sewickley ranks
Sewickley scores 32nd nationally and 42nd within Pennsylvania — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Sewickley ranks 21,573 for wildfire risk (1 is highest) and 8,426 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,161 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Shopping for coverage in Sewickley

What would actually reduce this score
Sewickley's 90.8% 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.
