Post Mountain, CA
How exposed is Post Mountain to wildfire?
Post Mountain's 401 buildings earn a 100th-percentile wildfire-risk score nationally under USFS's model — in USFS's highest wildfire-risk band nationally. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Post Mountain at the 100th national percentile — 0 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
Of Post Mountain's 401 counted buildings, 100% carry Direct exposure and only 0% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
Where Post Mountain ranks
Post Mountain scores 100th nationally and 98th within California — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Post Mountain ranks 65 for wildfire risk (1 is highest) and 19,179 by building count (1 is largest). Within California alone, it ranks 42 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Post Mountain and the insurance market
Post Mountain sits in California, one of two states that legally require a wildfire-risk disclosure at sale. California's FAIR Plan, the state's insurer of last resort, ended 2025 with 668,609 residential policies after adding 21,859 in Q4 alone — the kind of market shift a 100th-percentile score like Post Mountain's can end up mattering for.

Lowering exposure, not just insuring around it
With 100% of Post Mountain 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.
