Agoura Hills Fire History: The Woolsey Corridor

The fire came down the 101, and Agoura Hills was the crossing

At 2:22 pm on November 8, 2018, Southern California Edison logged an outage on its Big Rock 16 kV circuit at the Santa Susana Field Laboratory, in the hills south of Simi Valley. Two minutes later, a brush fire was reported. Investigators later concluded SCE electrical equipment started it.

Santa Ana winds did the rest. Overnight into the early hours of November 9, the fire crossed the 101 freeway near Liberty Canyon, the same wildlife corridor Agoura Hills is now famous for, and spread through the canyons on the city's southern edge.

By November 10 the region saw an unprecedented total evacuation: all of Agoura Hills, along with Oak Park, Malibou Lake, Bell Canyon, and Malibu. One of the fire's three deaths was discovered on Lobo Canyon Road in the Agoura area. Homes burned at the city's canyon edges and in the surrounding unincorporated communities; the nearby Seminole Springs mobile home park lost roughly 110 homes.

Landmarks this city grew up with burned too. Paramount Ranch's Western Town, the film set in the mountains just south of the city, was largely destroyed. Agoura Hills and Westlake Village were among the first communities repopulated, days later, to streets of ash-covered cars and standing homes that had held the line.

From the Woolsey run to the Zone 0 rule

Woolsey moved faster than any brush clearance rule anticipated: from ignition to the ocean in under 24 hours. What that speed proved is that the fight is not at the fire front. It is at each house, in the five feet where embers land.

Two years later the legislature passed AB 3074 and created the ember-resistant zone. The Santa Monica Mountains corridor has burned again since, Franklin in 2024 and the Palisades Fire in January 2025 to the east, and each event has pushed the state closer to final Zone 0 adoption, now expected late 2026.

Locally, the response layered up: the city's Community Wildfire Protection Plan and Community Wildfire Risk Assessment Project, the volunteer Agoura Hills Fire Safe Council, and the 2025 hazard remap that expanded the city's Very High zones. The maps now say what November 2018 already demonstrated.
