Westmont, CA
Westmont, CA's wildfire risk, in USFS's own numbers
Westmont sits at the 37th percentile nationally for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — per USFS's Wildfire Risk to Communities model, built from its 8,960 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Westmont at the 46th percentile, close to its 37th-percentile risk score.
Westmont's building exposure, zone by zone
Most of Westmont's buildings (100% of 8,960) fall outside USFS's Direct and Indirect zones entirely — that doesn't zero out the score above, it means the risk is regional, not structure-by-structure. At 8,960 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Westmont against the rest of the country
Westmont ranks lower within California (5th percentile statewide) than its 37th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Westmont ranks 19,720 for wildfire risk (1 is highest) and 1,859 by building count (1 is largest). Within California alone, it ranks 1,491 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
Westmont's 37th-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
With 100% of buildings rated Minimal exposure, Westmont gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
More on how this number was built
Westmont's 37th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what minimal exposure implies beyond Westmont, see the exposure-zones guide.
