Ambridge, PA
Ambridge wildfire risk explained
Ambridge sits at the 31st 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 2,838 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Ambridge's burn probability — fire likelihood with no building count factored in — sits at the 30th percentile nationally.
Where Ambridge's buildings actually sit
Most of Ambridge's buildings (99.8%) 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.
How Ambridge compares
Ambridge's risk sits at a similar level relative to Pennsylvania (39th 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, Ambridge ranks 21,917 for wildfire risk (1 is highest) and 5,683 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,211 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Ambridge and the insurance market
At the 31st national percentile, Ambridge 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
With ember exposure the dominant pattern in Ambridge (99.8% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
