A hillside crisis on the California coast—and what it means for Marin
In Rancho Palos Verdes, an ancient landslide complex has started moving again, and lately, it’s picked up speed—sometimes as much as a foot per week. The area’s clay-heavy soils and closeness to the ocean make it especially prone to sliding, and those relentless 2023–24 rains just made things worse.
Now, the landslide spans about 700 acres—almost twice what experts thought before. Houses have split, floors slant, and property lines don’t mean much when the ground won’t stay put.
If you’re in Marin County, here’s the uncomfortable truth: living on or near a coastal hillside means you’re rolling the dice, no matter how long you’ve called it home. In places like Mill Valley, Fairfax, Tiburon, and San Rafael, shifting ground isn’t just some disaster headline—it can mean blackouts, mortgage chaos, and tough calls about fixing up or moving out.
Impact on homes, insurance, and the real estate market
At least 24 homes are now unlivable, and thousands have lost gas and electricity as utility companies cut off large chunks of the neighborhood. Around 172 homes lost service, so many families are running on generators and whatever off-grid hacks they can manage while the earth keeps moving.
Property values have tanked. Insurance companies aren’t eager to cover landslide damage, and lenders have started clamping down, worried about falling prices and the cost of repairs. Still, bargain hunters keep showing up.
Since 2024, at least 11 homes inside the slide zone have sold. Some buyers see a deal in coastal real estate, but whether they can actually live there long-term is anyone’s guess.
One buyer, Eilen Stewart, took a big gamble. She’s put about $200,000 into upgrades—solar panels, propane, and a steel-beam “raft” under her house—to try and keep her home stable and livable while the ground keeps shifting.
Community response and ongoing mitigation efforts
Neighbors have stepped up, building a sort of DIY support network. They run dewatering wells every morning to lower groundwater and turn them off at night. When cracks open up, they haul in dirt to patch things over.
Sharing generators and trading supplies has become routine. This crisis has pulled people together, even as it tests everyone’s patience and nerves.
The city’s thrown serious cash at the problem—about $65 million on mitigation since 2022, which is way more than the usual annual budget. Officials have stopped new home construction in the slide zone and keep chasing state and federal emergency funds, though that’s been a slow grind.
Southern California Edison says they won’t restore power unless the ground slows to under one inch per week. SoCalGas uses advanced modeling to decide if it’s safe to turn the gas back on.
- Resilience in action: neighbors share resources, tackle dewatering, and rig up temporary power to keep homes running.
- Long odds, long timelines: funding is still up in the air, and new building is on hold in the danger zone.
- Real estate shift: it’s a blunt reminder for Marin buyers—coastal properties come with real geotechnical risks.
What Marin County can learn from this California coastline saga
If you live in San Rafael, Mill Valley, Larkspur, Sausalito, or anywhere nearby, the Portuguese Bend situation should get your attention. It’s a good reminder to check your hillside’s geology and drainage—especially if you’re up in the slopes above Corte Madera or tucked along San Anselmo’s winding streets.
Don’t wait until something goes wrong to prepare for utility interruptions or tricky insurance claims. Take photos of your home improvements, stash away reliable back-ups for power and heat, and maybe set aside a little for losses insurance won’t cover.
It’s also worth connecting with your city or town. Find out what mitigation programs or emergency plans they offer, and ask about flood or landslide risk disclosures if you’re buying or selling property.
In Marin, folks take pride in the mix of natural beauty and practical know-how. Here, proactive maintenance and solid emergency plans matter just as much as whatever the weather brings.
Engineers, policymakers, and neighbors in Fairfax, San Rafael, and Tiburon all have a say in future protections. If you’re a resident, it pays to stay in the loop, build neighborhood connections, and look at coastal real estate with a bit of curiosity—and maybe a dash of caution.
Whether you’re near the hills of Mill Valley or the bluffs of Sausalito, the Portuguese Bend story is a nudge to stay alert, invest in resilience, and keep those community ties strong—even when you’d rather not think about the ground shifting under your feet.
