Picture the minute hand at about 8 previous the hour. That’s the slope of Viet’s yard in southern Los Angeles County. It’s a bit too aggressive for a slip-and-slide. In truth, Viet doesn’t even let his 7-year-old daughter play on the household’s small again patio.

“I don’t need her falling down that hill,” he stated.

When Viet and his spouse purchased their house-on-a-hill 5 years in the past, it was a win, their piece of “the Hollywood Riviera,” as actual property brokers wish to name the world. (A self-employed marketer in his forties, Viet requested that his final identify not be used to guard his household’s privateness.)

Viet’s avenue runs horizontally throughout an enormous incline that begins the Palos Verdes Peninsula, a marvel of steep cliffs and Mediterranean-style houses on the south hook of Santa Monica Bay. If you squint, it could possibly be the terraced hills of Tuscany or, certainly, a stretch of the Côte d’Azur. The tackle was a stable funding and housing insurance coverage not an issue, although components of the peninsula have been recognized to shape-shift, cracking roads and knocking homes off foundations. But not day-after-day. The household loved some simple SoCal years on their perch with its nice views and delicate, dry local weather.

“Whenever it rained, we’d be happy: ‘We’re not in a severe drought anymore, yay!’” Viet stated. “But after this, every time it rains, I get scared.”

“This” was the atmospheric river storms that hit LA with a one-two punch (the primary, a jab, the second, a wallop) within the first week of February. The ordinary winter wet season in California has been amped up this yr by a parade of such storms. This week once more, Santa Barbara, Ventura, and LA counties are within the midst of high-volume, road-cracking, flash-flooding, climate-amplified downpours juiced by hotter Pacific Ocean temperatures. The storms are inflicting an uncommon quantity of high-profile harm, setting everybody on edge, particularly Viet.

After the preliminary rain burst on February 1, he observed that the highest of his yard slope, swathed in a hand-high succulent referred to as “ice plant,” regarded odd. A patch of mushy soil appeared to be shrugging off its floor cowl. He requested a gardener to try to repair it. That was a Friday. Then the monster rain cells moved in on Sunday, February 3.

“All night, all I could hear was pounding on the roof, the wind blowing sideways,” he stated. “It was unsettling, so when I woke up at 7:30, the first thing I did was try to go look at the rain drains and make sure everything was doing fine.”

Viet circled his house in sneakers as a result of he’d by no means had trigger to purchase rain boots.

“I walked around to the backyard, looked down, and I was like, ‘Ohhhhh myyyyyy goooood.’”

A 40-foot-wide river of mud, rock, and roots was in full circulation down his hill, already jamming up a metropolis street 70 toes beneath the place Viet stood, by some means secure, on the precipice.
