Arroyo Grande, CA
Arroyo Grande wildfire risk explained
Out of every US place USFS scores, Arroyo Grande lands at the 84th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 8,039 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Arroyo Grande at the 84th percentile, close to its 84th-percentile risk score.
Arroyo Grande's building exposure, zone by zone
USFS puts 44.9% of Arroyo Grande's 8,039 buildings in the Indirect exposure zone, versus 13.3% Direct and 41.8% Minimal — a place where the fire doesn't need to reach the structure directly for embers to. At 8,039 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Arroyo Grande compares
Inside California, Arroyo Grande sits at just the 47th percentile even though it scores 84th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Arroyo Grande ranks 5,129 for wildfire risk (1 is highest) and 2,099 by building count (1 is largest). Within California alone, it ranks 840 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Arroyo Grande and the insurance market
Because Arroyo Grande 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
With ember exposure the dominant pattern in Arroyo Grande (44.9% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
