Glen Rock, NJ
Glen Rock wildfire risk explained
Out of every US place USFS scores, Glen Rock lands at the 20th percentile for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — a figure built from its 4,598 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Glen Rock at the 22nd national percentile — 2 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Glen Rock rates 61.8% Minimal exposure against just 38.2% Direct and 0% Indirect — of 4,598 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually.
Glen Rock against the rest of the country
Glen Rock's risk sits at a similar level relative to New Jersey (6th percentile statewide) as it does nationally (20th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Glen Rock ranks 25,124 for wildfire risk (1 is highest) and 3,709 by building count (1 is largest). Within New Jersey alone, it ranks 658 of 700 places by risk. See the full county-by-county picture for New Jersey on its state page.
Glen Rock and the insurance market
Glen Rock's moderate wildfire rating (20th percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
What would actually reduce this score
Even with 61.8% of Glen Rock 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 Glen Rock's figures come from
Glen Rock's 20th-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 Glen Rock's dominant minimal exposure actually means, with real examples from across the dataset.
