Willow Grove, PA
How exposed is Willow Grove to wildfire?
Out of every US place USFS scores, Willow Grove lands at the 19th percentile for wildfire risk to structures — among the lower wildfire-risk places nationally — a figure built from its 4,518 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Willow Grove at the 19th percentile, close to its 19th-percentile risk score.
Where Willow Grove's buildings actually sit
Only 15.1% of Willow Grove's 4,518 buildings carry Direct exposure and 34.4% carry Indirect; the remaining 50.5% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure.
Where Willow Grove ranks
Willow Grove scores 19th nationally and 21st within Pennsylvania — close enough that its state context doesn't change the picture the national number already gives.

Within Pennsylvania alone, it ranks 1,583 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Shopping for coverage in Willow Grove
At the 19th national percentile, Willow Grove 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 Willow Grove
Even with 50.5% of Willow Grove outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
Where Willow Grove's figures come from
Willow Grove's 19th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Willow Grove's dominant minimal exposure actually means, with real examples from across the dataset.
