Castella, CA
How exposed is Castella to wildfire?
Castella's 218 buildings earn a 100th-percentile wildfire-risk score nationally under USFS's model — in USFS's highest wildfire-risk band nationally. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Castella at the 100th national percentile — 0 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Castella's buildings actually sit
USFS classifies 78.9% of Castella's buildings as Direct exposure, higher than its 21.1% Indirect share and far above its 0% Minimal share — a profile where 172 structures sit close enough to vegetation that lot clearing matters most.
How Castella compares
Castella scores 100th nationally and 98th within California — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Castella ranks 52 for wildfire risk (1 is highest) and 24,182 by building count (1 is largest). Within California alone, it ranks 29 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Castella and the insurance market
Castella's 100th-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.
Lowering exposure, not just insuring around it
Castella's 78.9% Direct-exposure share means lot clearing around the structure typically outweighs any single material upgrade here. The home-hardening guide ranks the options for a place shaped like this.
More on how this number was built
Castella's 100th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what direct exposure implies beyond Castella, see the exposure-zones guide.
