Ambridge Heights, PA
Ambridge Heights, PA's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Ambridge Heights at the 33rd national percentile for risk to structures, close to the middle of USFS's national wildfire-risk range — a score built from 770 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Ambridge Heights at the 32nd national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.
Ambridge Heights's building exposure, zone by zone
Most of Ambridge Heights's buildings (67.8%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
Where Ambridge Heights ranks
Ambridge Heights scores 33rd nationally and 45th 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, Ambridge Heights ranks 21,158 for wildfire risk (1 is highest) and 13,917 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,102 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Ambridge Heights and the insurance market
Ambridge Heights's moderate rating (33rd 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
Ambridge Heights's 67.8% 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.
