Norristown, PA
Norristown, PA's wildfire risk, in USFS's own numbers
USFS scores Norristown at the 7th national percentile for wildfire risk to structures (among the lower wildfire-risk places nationally), a figure built from 5,428 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Norristown's burn probability — fire likelihood with no building count factored in — sits at the 8th percentile nationally.
What "at risk" means for the buildings here
Only 2.9% of Norristown's 5,428 buildings carry Direct exposure and 0% carry Indirect; the remaining 97.1% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure. At 5,428 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Norristown against the rest of the country
There's little gap between Norristown's 7th national percentile and its 4th percentile inside Pennsylvania, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Norristown ranks 29,392 for wildfire risk (1 is highest) and 3,185 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,914 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
Norristown's low rating (7th percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Lowering exposure, not just insuring around it
With 97.1% of buildings rated Minimal exposure, Norristown gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
