Las Lomas, CA
How exposed is Las Lomas to wildfire?
Las Lomas's 839 buildings earn a 70th-percentile wildfire-risk score nationally under USFS's model — well above the national norm for wildfire risk. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Las Lomas's burn probability — fire likelihood with no building count factored in — sits at the 72nd percentile nationally.
Where Las Lomas's buildings actually sit
USFS puts 72.9% of Las Lomas's 839 buildings in the Indirect exposure zone, versus 27.1% Direct and 0% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
Las Lomas against the rest of the country
Las Lomas's 70th national percentile looks worse in isolation than its 28th ranking inside California does — this place is on the milder end for its own state, by 43 points. Among the 31,521 US communities USFS scores, Las Lomas ranks 9,319 for wildfire risk (1 is highest) and 13,255 by building count (1 is largest). Within California alone, it ranks 1,134 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Las Lomas and the insurance market
Las Lomas's 70th-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 72.9% of Las Lomas'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.
