The Brief

An unusually strong storm system has reached Southern California, raising fears that the rain could unleash a threat that has been lingering in the burn scars of wildfires that ravaged Los Angeles communities in recent years.

Called debris flows, these fast-moving slurries of floodwater and sediment can hurtle down slopes carrying cars, trees and even boulders with them.

They’re like “a flood on steroids,” said Jason Kean, a research hydrologist with the U.S. Geological Survey’s landslide hazards program. “It’s really hard to stop these things. The best thing to do is get out of the way.”

Forecasters expect the heaviest rain Friday into Saturday night; predictions are for wet days through next week. Storms may stretch from Santa Barbara County south to Los Angeles County, and could spread inland to parts of Orange County and the Inland Empire.

Burn scars — slicked by fire and stripped of plants — are especially vulnerable. A storm after the Thomas Fire in 2018 spurred debris flows in Montecito that killed 23 people. And in February, a debris flow in the Palisades Fire burn zone swept a Los Angeles Fire Department member and his SUV into the Pacific Ocean.

The Los Angeles County Department of Public Works warns that there’s a risk of moderate debris and mudflows capable of blocking roadways and endangering some structures in the burn scars of almost a dozen fires — including January’s Eaton, Hurst and Palisades fires.

The county has issued evacuation warnings, as well as some targeted evacuation orders for specific properties “at higher risk for mud and debris flows impacts.”

The public works department says that most burned properties have been cleared of fire debris, and the rest have been shored up with gravel bags and other materials to keep debris in place.

Gov. Gavin Newsom also announced today that more than 400 personnel and resources including fire engines, helicopters and search and rescue teams have been pre-deployed to Southern California counties.

“It’s a pretty serious situation,” said National Weather Service meteorologist David Gomberg.

By Friday morning, the storm had already unleashed up to 5 inches of rain in parts of Santa Barbara County, Gomberg said, and Southern California is bracing for more.

There’s also the possibility of thunderstorms, small tornadoes, and a worrying amount of rain hitting the Eaton and Palisades burn scars. Even just a half-an-inch to 0.6 inches of rain could trigger a debris flow in these areas, said Gomberg, who added that his office is forecasting between half an inch to one inch per hour in these areas.

“And the more you exceed the threshold, the probability of a more damaging debris flow increases,” he said.

We spoke with the U.S. Geological Survey’s Kean, an expert on debris flows after wildfires, about what to expect. This conversation has been edited and condensed.

As this storm really takes hold in LA and Southern California, I'm hearing a lot of concern about it hitting areas that burned this past year, including in the Eaton and Palisades fires. Why is this such a big concern? What could happen?

Last January those fires removed much of the vegetation on really steep slopes, and that made those slopes really vulnerable to erosion during intense rainfall. That protective blanket of vegetation is gone, and heavy rain can rapidly make a flash flood. And that flood, in some cases, can pick up material and turn into what we call a debris flow — which is like a flood on steroids.

Photo by Joel Angel Juarez for CalMatters These burn areas are still vulnerable, even though it's now many months after the fire and there have been flows already. There's still plenty of material that could be mobilized. So the threat’s still there. And so we know they're bad actors, and we’re concerned they could be bad actors again.

I’m hearing a lot of different terms: mudslide, debris flows, landslide. What are the differences, and which ones are the burn scars at risk for? 

Landslide is an umbrella term that captures all kinds of mass movements, from rock falls to debris flows — these floods on steroids — to big, slow movers. The type of flow that we're most concerned about in a recent burn area is a debris flow. It's also called a mudslide. But geologists don't like to use the word mudslide as much because it sounds like there's some mud on your driveway — not a big issue, not something that could kill you. And these things, if you're in the wrong spot at the wrong time, they can cause serious damage.

You called it a flood on steroids. What happens in a debris flow? 

Flash floods are bad, and they can cause lots of problems, too. They can get even worse if they pick up enough sediment to turn into the consistency of wet concrete. But it's worse than just concrete, because it can contain boulders the size of cars. And, very close to the mountain front, it can move very quickly — faster than you can run. And when it gets all bulked up with debris, the rocks, the gravel, the mud, trees, the flow can be a lot bigger. It just turns into a different animal.

Now, debris flows pack a bigger punch than floods, but thankfully, they don't have as long of reach. So usually, the debris flows are confined really close to the mountain fronts. That's where they put those debris basins to catch them. But if there isn't one protection like that, then they can travel downslope and impact neighborhoods, and then flooding can extend even further down.

Is there something about Southern California that makes it higher risk?

Southern California's kind of the world capital for these kinds of events. It's got this combination of very steep topography, like the San Gabriel Mountains that just shoot right up, Santa Monica mountains, Santa Ynez — very steep topography. It burns fairly frequently. And then there are a lot of people living very close to the mountain front, so that's what puts the risk up.

The thing about a burn area is it takes much less rainfall to cause a problem than it would in unburned conditions. So we've now made the slopes really vulnerable. They're extra steep. There's a lot of people there. That's why the risk is so high.

We've seen debris flows in Northern California burn areas as well. It's not just a Southern California problem, and it's not just a California problem.

Is there anything that could have been done to reduce this risk? Anything that should be done now? 

Not long after the fires, in particular the Palisades Fire, (there were) a number of fairly widespread debris flows that disrupted the roads. There were also, in the Eaton fire, floods and debris flows there. Thankfully there's a dense network of LA County debris basins, which are designed to catch the material before it enters neighborhoods, and those largely saved the day.

Planners have planned ahead and put in these debris basins — these big, giant holes in the ground — designed to catch the material. That's the best defense against these. They're not everywhere, but there is a good network of protection. Other than that, it's really hard to stop these things.

What should people who live near the recent burn scars know? What should they do now, as the rain starts? 

The best thing you could do is, if you're really close to a drainage in one of these burn areas, is to get out of the way. You're going to get a heads up from the National Weather Service, who's closely monitoring the rainstorms. They know how much rain it's going to take to cause a problem, and they'll get out warnings, and local authorities will reach out to get people out of the way. So there's a lot of eyes on the situation. And so at this point, the best thing to do is listen to the weather service, listen to local authorities.

If they ask you to get out of the way, take their advice. These things can happen really fast if there is an intense burst of rain, a flash flood, where debris flow can start within minutes.

So there is no escaping a debris flow once it starts? 

It's pretty difficult. If you have a two-story home and you happen to be there at the wrong time, get up to that second floor for sure. Fight like heck if you get trapped in one. But best to be out of the way.

Since 1977, Richard Santillan has been to every Opening Day game at Dodger Stadium. 

“The tradition goes from my father, to me, to my children and grandchildren. Some of my best memories are with my father and children here at Dodger Stadium,” Santillan told The LA Local, smiling under the shade of palm trees near the entrance to the ballpark Wednesday morning. He was there to protest the team less than 24 hours before Opening Day.

Santillan, like countless other loyal Dodgers fans, is grappling with his fan identity over the team’s decision to accept an invitation to the White House and owner Mark Walter’s ties to ICE detention facilities.

More than 30 people joined Santillan on Wednesday morning for a press conference held near 1000 Vin Scully Drive to convey a message directly to the team. 

“We are demanding the Dodgers stop participating in funding of inhumane treatment of families and do not go to the White House to celebrate with the criminal in chief,” Evelyn Escatiola told the crowd. “Together, we have the power to make a change.”

Escatiola, a former dean of East Los Angeles College and longtime community organizer, urged fans to flex their economic power by “letting the Dodgers know that we do not support repression.”

Jorge “Coqui” Rodriguez, a lifelong Dodgers fan, spoke to the crowd and called on Dodgers ownership to divest from immigration detention centers owned and operated by GEO Group and CoreCivic.

In a phone interview a day before the protest, Rodriguez told The LA Local he did not want the Dodgers using his “cheve” or beer money to fund detention centers. 

“They can’t take our parking money, our cacahuate money, our cheve money, our Dodger Dog money and invest those funds into corporations that are imprisoning people. It’s wrong,” Rodriguez said. 

Rodriguez considers the Dodgers one of the most racially diverse teams and said the players need to support fans at a time when heightened immigration enforcement has become more common across L.A.

The team’s 2025’s visit to the White House drew ire from the largely Latino fan base, citing the Trump administration’s ongoing attacks on immigrants. 

In June, the team came under further scrutiny when rumors swirled online that federal immigration agents were using the stadium’s parking, which immigration authorities later denied in statements posted on social media accounts.

The team again came under fire after not releasing a statement on the impacts of ICE raids on its mostly Latino fan base at the height of immigration enforcement last summer. The team later agreed to invest $1 million to support families affected by immigration enforcement.

When he learned the Dodgers were pledging only $1 million to families in need, Rodriguez called the amount a  “slap in the face.” 

“These guys just bought the Lakers for billions of dollars and they give a million dollars to fight for legal services? That’s a joke,” Rodriguez said. “They need to have a moral backbone and not be investing in those companies.”

According to reporting from the Los Angeles Times, former Dodgers pitcher Clayton Kershawsaid last week that he is looking forward to the trip.

“I went when President [Joe] Biden was in office. I’m going to go when President [Donald] Trump is in office,” Kershaw said. “To me, it’s just about getting to go to the White House. You don’t get that opportunity every day, so I’m excited to go.”

The Dodgers have yet to announce when their planned visit will take place. 

Santillan sometimes laments his decision to give up his season tickets in protest of the team. His connection to the stadium and the memories he has made there with family and friends will last a lifetime, he said. On Thursday, he will uphold his tradition and be there for the first pitch of the season, but with a heavy heart.

“It’s a family tradition, but the Dodgers have a lot of work to do,” he said.

A local favorite mom-and-pop bookshop in Eagle Rock is facing displacement due to a steep rent hike. The owners say theirs is just one of several small businesses along Eagle Rock Boulevard struggling to keep up with lease increases.

Over the past 19 years, many in the neighborhood have come to love READ Books for its eclectic collection of used titles and shop dog Florence.

Co-owner Jeremy Kaplan said it’s been a delight to grow with the community over the years.

“Like seeing kids come back in, who were in grade school and now they’re in college,” Kaplan said.

But the building where Kaplan and wife Debbie rent was recently sold, and the rent increased by more than 130% to $2,805 a month, Kaplan said. He told LAist it was an increase his small business simply could not absorb.

Kaplan said he originally was given 30 days notice of the rent increase. After some research, assistance from Councilmember Ysabel Jurado’s office and some pro-bono legal help, Kaplan said he pushed back and got the 90-day notice he’s afforded by state law.

California Senate Bill 1103 requires landlords to give businesses with five or less employees 90 days’ notice for rent increases exceeding 10%, among other protections.

Systems Real Estate, the property management company, did not immediately respond to LAist’s request for comment.

What can small businesses do? 

Nadia Segura, directing attorney of the Small Business Program at pro bono legal aid non-profit Bet Tzedek said California law does not currently allow for rent control for commercial tenancies.

Outside of the protections under SB 1103, Segura said small businesses like READ Books don’t have much other recourse. And even then, commercial landlords are not required to inform their tenants of their protections under the law.

“There’s still a lot of people that don’t know about SB 1103. And then it’s very sad that they tell them they have these rent increases and within a month they have to leave,” Segura said.

She said her group is seeing steep rent hikes like this for commercial tenants across the city.

“We are seeing this even more with the World Cup coming up, the Olympics coming up. And I will say it was very sad to see that also after the wildfires,” Segura said.

Part of Bet Tzedek’s ongoing work is to advocate for small businesses, working with landlords who are increasing rents to see if they are willing to give business owners longer leases that lock in rents.

What’s next 

After READ Books posted about their situation on social media, commenters chimed in to express their outrage and love for the little shop.

While he looks for a new spot, Kaplan says he’s forming a coalition of local businesses and activist groups to see what can be done to help other small businesses facing similar displacement. He wants to address the displacement issue for businesses like his, which have made Eagle Rock the distinctive neighborhood that it is today.

Owl Talk, a longtime Eagle Rock staple selling clothing and accessories in a unit in the same building as READ Books, is facing a “more than double” rent increase, according to a post on their Instagram account.

Kaplan said he’s been in touch with the office of state Assemblywoman Jessica Caloza and wants to explore the possibility of introducing legislation to set up protections for small businesses like his, including rent-control measures or a vacancy tax for landlords. Kaplan said he also reached out to the office of state Sen. Maria Durazo.

By his count, Kaplan said there are about a dozen businesses within surrounding blocks that are at risk of closing their doors or have shuttered due to rent increases or other struggles.

When READ Books was founded during the Great Recession, Kaplan said he knew it was a longshot to open a bookstore at the same time so many were struggling to stay in business.

“It was kind of interesting to be doing something that neighborhoods needed. That was important to me growing up, that was important to my children, that was important to my wife growing up,” Kaplan said.

“And then somebody comes in and says, ‘We’re gonna over double your rent.”

Topline:

Frozen budget: Most of the city’s Bureau of Street Lighting budget comes from an assessment that people who own property illuminated by lights pay on their county property tax bill. The amount people pay depends on the kind of property they own and how much they benefit from lighting. A typical single-family home currently pays $53 annually, and in total, the assessments bring in about $45 million annually for the city to repair and maintain streetlights. Changing the amount the Bureau of Street Lighting gets from the assessment requires a vote among property owners who benefit from the lights.

Ballots: L.A. City Council’s vote gives city staff the green light to prepare and send out those ballots. Miguel Sangalang, who oversees the bureau, said at a committee meeting earlier this month that he expects to send out ballots by April 17. Notices about the ballots will be sent out prior to the ballots themselves.

Near unanimous vote: L.A. City Councilmember Monica Rodriguez was the only “No” vote Tuesday, saying she wanted to see a more current strategic plan for the bureau. Sangalang said the bureau developed a plan in 2022 that lays out how money will be spent. Councilmember Imelda Padilla was absent for the vote.

Vote count: Votes will be weighted according to the assessment amount. Basically, the more you’re asked to pay yearly to maintain streetlights, the more your vote will count. Ballots received before June 2 will be tabulated by the L.A. City Clerk.

How much more money: According to a report, the amount needed in assessments from property owners to meet the repair and maintenance needs of the city’s streetlighting in the next fiscal year is nearly $112 million.

Use of the money: Sangalang said at a March 11 committee meeting that the extra funds would be used to double the number of staff to handle repairs and procure solar streetlights, which don’t face the threat of copper wire theft. That would all potentially reduce the time it takes to repair simple fixes down to a week. Currently, city residents wait for months to see broken streetlights repaired. The assessment would come with a three-year auditing mechanism.
