Isleton, CA
Isleton wildfire risk explained
Isleton's 447 buildings earn a 65th-percentile wildfire-risk score nationally under USFS's model — well above the national norm for wildfire risk. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Isleton at the 63rd national percentile — 2 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Isleton's buildings actually sit
95.3% of Isleton's 447 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 4.7% Direct and 0% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
How Isleton compares
Isleton ranks lower within California (23rd percentile statewide) than its 65th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Isleton ranks 11,150 for wildfire risk (1 is highest) and 18,325 by building count (1 is largest). Within California alone, it ranks 1,213 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Isleton
Because Isleton 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
Isleton's 95.3% 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.
Where Isleton's figures come from
Isleton's 65th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Isleton's dominant indirect exposure actually means, with real examples from across the dataset.
