Cromberg, CA
Cromberg wildfire risk explained
USFS scores Cromberg at the 99th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 246 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Cromberg's burn probability — fire likelihood with no building count factored in — sits at the 99th percentile nationally.
Where Cromberg's buildings actually sit
Of Cromberg's 246 counted buildings, 100% carry Direct exposure and only 0% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
Cromberg against the rest of the country
Cromberg's risk sits at a similar level relative to California (91st percentile statewide) as it does nationally (99th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Cromberg ranks 243 for wildfire risk (1 is highest) and 23,257 by building count (1 is largest). Within California alone, it ranks 134 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Cromberg
Cromberg's 99th-percentile score lands in California, the only two states requiring a wildfire disclosure at sale. California's surplus-lines homeowners market passed 300,000 policies for the first time in 2025, driven by carriers pulling back from wildfire-exposed areas statewide. The disclosure-law guide covers what it requires.
What would actually reduce this score
Because Direct exposure dominates in Cromberg (100%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
