Humboldt Hill, CA
Humboldt Hill, CA's wildfire risk, in USFS's own numbers
Humboldt Hill's 1,579 buildings earn a 53rd-percentile wildfire-risk score nationally under USFS's model — modestly above the national average for wildfire risk. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Humboldt Hill at the 56th national percentile — 3 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
USFS puts 60.9% of Humboldt Hill's 1,579 buildings in the Indirect exposure zone, versus 39.1% Direct and 0% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
Humboldt Hill against the rest of the country
Inside California, Humboldt Hill sits at just the 13th percentile even though it scores 53rd 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, Humboldt Hill ranks 14,678 for wildfire risk (1 is highest) and 8,837 by building count (1 is largest). Within California alone, it ranks 1,367 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Humboldt Hill
Humboldt Hill sits in California, one of two states that legally require a wildfire-risk disclosure at sale. California's FAIR Plan, the state's insurer of last resort, ended 2025 with 668,609 residential policies after adding 21,859 in Q4 alone — the kind of market shift a 53rd-percentile score like Humboldt Hill's can end up mattering for.

Lowering exposure, not just insuring around it
With ember exposure the dominant pattern in Humboldt Hill (60.9% 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
Humboldt Hill's 53rd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Humboldt Hill, see the exposure-zones guide.
