Fire History
San Luis Obispo County's wildfire risk is concentrated in its eastern mountain communities and coastal range terrain. The 2021 Alisal Fire (18,000 acres) shut down Highway 101 near Gaviota at the county's southern border. The 2021 Riggi Fire burned near Paso Robles. Fires in the Los Padres National Forest backcountry regularly threaten communities along Highway 58 and the Carrizo Plain corridor. The county's combination of annual grasses, oak woodland, and chaparral creates persistent seasonal fire risk.
Local Compliance Notes
CAL FIRE San Luis Obispo Unit serves unincorporated SRA areas. Communities in the Santa Lucia Range foothills, areas east of US-101, and communities adjacent to the Los Padres National Forest face the most significant Zone Zero obligations. The relatively sparse WUI development in this county means fewer total properties affected, but those in FHSZ areas face the same compliance requirements as larger counties.
Neighborhoods in Zone Zero
High-FHSZ communities in SLO County include Atascadero foothills, Templeton area, Paso Robles eastern foothills, Santa Margarita, Creston, communities along Highway 58, Arroyo Grande foothills, and unincorporated areas adjacent to the Los Padres National Forest.
