Poso Park, CA
Poso Park wildfire risk explained
Out of every US place USFS scores, Poso Park lands at the 99th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 19 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Poso Park's burn probability — fire likelihood with no building count factored in — sits at the 99th percentile nationally.
Poso Park's building exposure, zone by zone
19 buildings are counted in Poso Park, and 100% of them sit in USFS's Direct exposure zone — flame contact, not just ember cast, is the live possibility for most of them, against 0% rated Minimal. This is a small settlement by building count — 19 total — so these shares describe a handful of structures, not a statistical average across thousands.
Where Poso Park ranks
Poso Park scores 99th nationally and 88th 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, Poso Park ranks 375 for wildfire risk (1 is highest) and 31,463 by building count (1 is largest). Within California alone, it ranks 186 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Poso Park
Poso Park 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 99th-percentile score like Poso Park's can end up mattering for.

Lowering exposure, not just insuring around it
Because Direct exposure dominates in Poso Park (100%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
More on how this number was built
The methodology guide shows exactly how USFS turned 19 counted buildings into the percentiles shown above for Poso Park. At 19 buildings, Poso Park is close to the size where USFS's data gets thin — the data-quality guide explains why 517 places nationally get no score at all.
