What "at risk" means for the buildings here
86.1% of Trabuco Canyon's 613 buildings sit in USFS's Direct exposure zone, roughly 528 structures close enough to burnable vegetation for flame contact, not just embers — 13.9% fall in the Indirect, ember-only zone and 0% are Minimal.

What this risk score means for insurance
Trabuco Canyon'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.
What would actually reduce this score
With 86.1% of Trabuco Canyon in Direct exposure, defensible-space clearing and ember-resistant construction (vents, Class-A roofing) address the exposure this page's own numbers describe, not a generic checklist. See the home-hardening guide.
