Allison, PA
How exposed is Allison to wildfire?
Allison's 373 buildings earn a 33rd-percentile wildfire-risk score nationally under USFS's model — close to the middle of USFS's national wildfire-risk range. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Allison at the 35th percentile, close to its 33rd-percentile risk score.
Allison's building exposure, zone by zone
71.6% of Allison's 373 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 28.4% Direct and 0% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
Where Allison ranks
Allison's risk sits at a similar level relative to Pennsylvania (45th percentile statewide) as it does nationally (33rd) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Allison ranks 21,157 for wildfire risk (1 is highest) and 19,812 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,101 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
What this risk score means for insurance
Allison'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.
Hardening a home in Allison
Allison's 71.6% 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.
