Coraopolis, PA
Coraopolis wildfire risk explained
USFS's Wildfire Risk to Communities model puts Coraopolis at the 30th national percentile for risk to structures, close to the middle of USFS's national wildfire-risk range — a score built from 3,017 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Coraopolis at the 30th percentile, close to its 30th-percentile risk score.
Coraopolis's building exposure, zone by zone
Most of Coraopolis's buildings (90.4%) 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 Coraopolis ranks
Coraopolis's risk sits at a similar level relative to Pennsylvania (38th percentile statewide) as it does nationally (30th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Coraopolis ranks 22,071 for wildfire risk (1 is highest) and 5,406 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,226 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Coraopolis and the insurance market
At the 30th national percentile, Coraopolis rates moderate for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
What would actually reduce this score
With ember exposure the dominant pattern in Coraopolis (90.4% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
