Port Jefferson, NY
How exposed is Port Jefferson to wildfire?
Out of every US place USFS scores, Port Jefferson lands at the 32nd percentile for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — a figure built from its 2,824 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Port Jefferson at the 33rd national percentile — 1 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
Direct exposure dominates in Port Jefferson: 63% of its 2,824 buildings, versus 36.8% Indirect and 0.2% Minimal. Clearing space around a structure changes the outcome here more than any single building-material swap.

Port Jefferson and the insurance market
Port Jefferson's moderate wildfire rating (32nd 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.
Lowering exposure, not just insuring around it
With 63% of Port Jefferson in Direct exposure, defensible-space clearing and ember-resistant construction (vents, Class-A roofing) address the exposure this page's own numbers describe, not a generic checklist. See the home-hardening guide.
