East Porterville, CA
How exposed is East Porterville to wildfire?
USFS's Wildfire Risk to Communities model puts East Porterville at the 86th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 1,961 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts East Porterville at the 89th percentile, close to its 86th-percentile risk score.
Where East Porterville's buildings actually sit
43.4% of East Porterville's 1,961 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 38.4% Direct and 18.3% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
Where East Porterville ranks

Within California alone, it ranks 735 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in East Porterville
East Porterville 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 86th-percentile score like East Porterville's can end up mattering for.

Lowering exposure, not just insuring around it
Because 43.4% of East Porterville's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
More on how this number was built
East Porterville's 86th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond East Porterville, see the exposure-zones guide.
