Chambersburg, PA
Chambersburg, PA's wildfire risk, in USFS's own numbers
Chambersburg sits at the 13th 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 6,603 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 Chambersburg at the 15th percentile, close to its 13th-percentile risk score.
What "at risk" means for the buildings here
Chambersburg rates 95.9% Minimal exposure against just 4.1% Direct and 0% Indirect — of 6,603 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually. At 6,603 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.

Chambersburg and the insurance market
At the 13th national percentile, Chambersburg rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Hardening a home in Chambersburg
With 95.9% of buildings rated Minimal exposure, Chambersburg gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
