Grand Isle, ME
Grand Isle, ME's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Grand Isle at the 10th national percentile for risk to structures, among the lower wildfire-risk places nationally — a score built from 203 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Grand Isle at the 9th national percentile — 0 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Grand Isle's buildings actually sit
USFS puts 51.7% of Grand Isle's 203 buildings in the Indirect exposure zone, versus 48.3% Direct and 0% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
How Grand Isle compares
Within Maine, Grand Isle ranks higher (46th percentile) than it does nationally (10th) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Grand Isle ranks 28,493 for wildfire risk (1 is highest) and 24,733 by building count (1 is largest). Within Maine alone, it ranks 84 of 155 places by risk. See the full county-by-county picture for Maine on its state page.
Grand Isle and the insurance market
At the 10th national percentile, Grand Isle 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
Grand Isle's 51.7% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
