Deltana, AK
Deltana wildfire risk explained
USFS's Wildfire Risk to Communities model puts Deltana at the 96th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 2,220 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Deltana at the 96th percentile, close to its 96th-percentile risk score.
Deltana's building exposure, zone by zone
USFS classifies 95.2% of Deltana's buildings as Direct exposure, higher than its 4.7% Indirect share and far above its 0.1% Minimal share — a profile where 2,114 structures sit close enough to vegetation that lot clearing matters most.
Where Deltana ranks
Deltana's risk sits at a similar level relative to Alaska (89th percentile statewide) as it does nationally (96th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Deltana ranks 1,215 for wildfire risk (1 is highest) and 6,881 by building count (1 is largest). Within Alaska alone, it ranks 37 of 322 places by risk. See the full county-by-county picture for Alaska on its state page.
Deltana and the insurance market
Deltana's 96th-percentile, very high rating is the kind of score behind a broader national pattern: insurers pulling back from the highest wildfire-risk markets, non-renewing or declining new policies outright, most visibly in California. Shopping around, not assuming automatic renewal, tends to matter here.
Hardening a home in Deltana
Because Direct exposure dominates in Deltana (95.2%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
Where Deltana's figures come from
Deltana's 96th-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 Deltana's dominant direct exposure actually means, with real examples from across the dataset.
