Delleker, CA
Delleker, CA's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Delleker lands at the 99th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 439 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Delleker at the 98th percentile, close to its 99th-percentile risk score.
Where Delleker's buildings actually sit
USFS puts 57.4% of Delleker's 439 buildings in the Indirect exposure zone, versus 42.6% Direct and 0% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
Delleker against the rest of the country
There's little gap between Delleker's 99th national percentile and its 86th percentile inside California, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Delleker ranks 468 for wildfire risk (1 is highest) and 18,472 by building count (1 is largest). Within California alone, it ranks 214 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
What this risk score means for insurance
Because Delleker is in California, a wildfire-hazard disclosure is legally required before a sale closes here — unusual nationally, since only these two states mandate it. The state's FAIR Plan alone carried 668,609 policies by the end of 2025. Full detail in the disclosure-law guide.
What would actually reduce this score
Because 57.4% of Delleker's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
More on how this number was built
Delleker's 99th-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 Delleker, see the exposure-zones guide.
