Koyuk, AK
Koyuk wildfire risk explained
USFS scores Koyuk at the 84th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 122 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Koyuk's burn probability — fire likelihood with no building count factored in — sits at the 84th percentile nationally.
What "at risk" means for the buildings here
Most of Koyuk's buildings (86.9%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
How Koyuk compares
Inside Alaska, Koyuk sits at just the 67th percentile even though it scores 84th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Koyuk ranks 5,158 for wildfire risk (1 is highest) and 28,046 by building count (1 is largest). Within Alaska alone, it ranks 108 of 322 places by risk. See the full county-by-county picture for Alaska on its state page.
Koyuk and the insurance market
Koyuk's very high rating (84th percentile) puts it among the places where the national carrier-pullback trend is most relevant — not a guarantee of a coverage problem, but a reason to shop rather than assume.
Lowering exposure, not just insuring around it
With ember exposure the dominant pattern in Koyuk (86.9% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
More on how this number was built
Every one of the two percentiles behind Koyuk's 5,158-place national rank traces to USFS's Wildfire Risk to Communities dataset — see the methodology guide. For more on what indirect exposure implies beyond Koyuk, see the exposure-zones guide.
