Port Huron, MI
How exposed is Port Huron to wildfire?
USFS's Wildfire Risk to Communities model puts Port Huron at the 8th national percentile for risk to structures, among the lower wildfire-risk places nationally — a score built from 12,492 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Port Huron's burn probability — fire likelihood with no building count factored in — sits at the 9th percentile nationally.
What "at risk" means for the buildings here
98% of Port Huron's 12,492 buildings sit in USFS's Minimal exposure zone, with only 2% rated Direct — risk here comes from regional burn probability more than proximity to burnable vegetation at the structure itself. At 12,492 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Port Huron ranks
Compare Port Huron's two percentiles: 24th within Michigan, only 8th nationally — a gap of 16 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Port Huron ranks 28,996 for wildfire risk (1 is highest) and 1,233 by building count (1 is largest). Within Michigan alone, it ranks 567 of 745 places by risk. See the full county-by-county picture for Michigan on its state page.
Port Huron and the insurance market
Port Huron's low rating (8th percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Hardening a home in Port Huron
With 98% of buildings rated Minimal exposure, Port Huron gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
Where Port Huron's figures come from
Port Huron's 8th-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 Port Huron's dominant minimal exposure actually means, with real examples from across the dataset.
