Marietta, PA
Marietta wildfire risk explained
Marietta sits at the 7th percentile nationally for wildfire risk to structures — among the lower wildfire-risk places nationally — per USFS's Wildfire Risk to Communities model, built from its 883 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Marietta at the 6th percentile, close to its 7th-percentile risk score.
What "at risk" means for the buildings here
USFS puts 85.1% of Marietta's 883 buildings in the Indirect exposure zone, versus 15% Direct and 0% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
How Marietta compares
Marietta scores 7th nationally and 4th 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, Marietta ranks 29,452 for wildfire risk (1 is highest) and 12,881 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,916 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Marietta and the insurance market
At the 7th national percentile, Marietta rates low 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
Because 85.1% of Marietta's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
