The Peninsula's Fire Record, Honestly Told
The night Portuguese Bend burned
On the evening of August 27, 2009, a brush fire broke out near Portuguese Bend in Rancho Palos Verdes and moved upslope into Rolling Hills. By morning it had burned roughly 230 acres of coastal sage and canyon fuel.
More than a thousand residents were evacuated from Portuguese Bend and streets including Amber Sky Drive, Southfield Drive, and Crest Road. Hundreds of firefighters from LA County, LA City, and Torrance responded, backed by helicopters and fixed-wing aircraft dropping ocean water. Homes on Cinchring Road and Quail Ridge Road in Rolling Hills were damaged. No homes were destroyed. No one was injured.
The after-action lesson was blunt: county fire officials noted that where homes were saved, owners had completed proper brush clearance and planted fire-resistant vegetation. The homes that were prepared before the fire were the homes that made it.
Why Zone 0 matters on terrain this lucky, and this fragile
The Peninsula's biggest fire asset is also its biggest fuel bed. The Portuguese Bend landslide, moving since 1956, kept the area from being built out. What remains is the largest block of natural coastal sage scrub on the Peninsula, much of it now within the Palos Verdes Nature Preserve, roughly 1,400 acres of protected habitat managed with the Palos Verdes Peninsula Land Conservancy.
That habitat shelters species found almost nowhere else on the mainland coast. It also stands, dry for most of the year, directly against fences and rail lines from Portuguese Bend up through the canyons of Rolling Hills, where equestrian properties keep barns, hay, and long wood rail runs close to open fuel.
The land movement adds a complication no other South Bay community has: the slide has repeatedly broken roads and utilities, and in 2024 accelerating movement forced utility shutoffs in parts of Portuguese Bend. Fewer intact routes means evacuation and fire access planning matter more here, not less. The Peninsula cities run a shared evacuation-zone program, PVPready, for exactly this reason.
Fire history questions, answered
Has the Peninsula ever had a catastrophic fire?
Not on the scale of Malibu or the Palisades, and this site will not pretend otherwise. The Peninsula's defining event is the August 2009 Portuguese Bend fire: roughly 230 acres, more than a thousand residents evacuated, homes damaged in Rolling Hills, none destroyed. The record shows real risk with narrow escapes, not devastation.
What happened in the August 2009 Portuguese Bend fire?
A brush fire broke out on the evening of August 27, 2009 near Portuguese Bend in Rancho Palos Verdes and pushed into Rolling Hills, burning roughly 230 acres. More than a thousand residents were evacuated from Portuguese Bend and surrounding streets, hundreds of firefighters responded with helicopters and fixed-wing aircraft, and homes on Cinchring Road and Quail Ridge Road were damaged. No homes were destroyed and no injuries were reported.
Why does the Portuguese Bend landslide matter to fire risk?
The active landslide keeps the Portuguese Bend area lightly developed, which preserves the largest block of coastal sage scrub habitat on the Peninsula, standing fuel that runs up against homes. Land movement has also broken roads and utilities at times, which complicates both evacuation routes and firefighting access. Fire planning here has to respect the geology.
If no homes were destroyed in 2009, why does Zone Zero apply here?
Because the 2009 outcome was earned, not guaranteed. Firefighters credited the aircraft attack and the properties that had already done brush clearance and planted fire-resistant vegetation. Zone Zero turns that voluntary preparation into a baseline, and the 2025 CAL FIRE remap confirms Very High hazard zones exist on the Peninsula.

In 2009, preparation decided which homes came through. A free assessment tells you exactly what yours needs.
