Valle Vista, CA
Valle Vista wildfire risk explained
USFS scores Valle Vista at the 99th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 6,577 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Valle Vista at the 99th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
80.4% of Valle Vista's 6,577 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 13.9% Direct and 5.7% Minimal. Vent screens and roofing material matter more here than lot clearing alone. At 6,577 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Valle Vista compares
Valle Vista's risk sits at a similar level relative to California (87th 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, Valle Vista ranks 410 for wildfire risk (1 is highest) and 2,637 by building count (1 is largest). Within California alone, it ranks 200 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 Valle Vista 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
Valle Vista's 80.4% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
