trash-interceptor plan – Los Angeles and San Gabriel rivers would get trash-intercepting devices by 2028 to stop hundreds of tons of debris reaching the Pacific.
On a stretch of the San Gabriel or Los Angeles River. it is possible to spot more than weeds and sand: abandoned bottles. wrappers. golf balls. even shopping carts.. When rain comes to Southern California’s usually dry landscape, the debris does what people may never notice it doing.. It travels with the water into coastal communities and out to sea. carrying harm to an ecosystem shared by fish. sea lions and surfers.
City. county. state and private partners say they have a plan to change that by the 2028 Olympics. deploying trash-intercepting devices in both the Los Angeles River and the San Gabriel River.. Officials on Wednesday described the project as a major milestone toward preventing hundreds of tons of garbage from reaching the Pacific.
For Seal Beach City Councilmember Joe Kalmick, the effort has the feel of a long-promised fix. Living in the beach city for more than 50 years, he said he often wondered why nothing could be done about the trash arriving from the San Gabriel River.
“The problem always seemed to be too overwhelming and solutions out of reach,” Kalmick said at a news conference. “I kind of felt like Don Quixote.”
He said his interest turned into action about three years ago. after reading about a Dutch nonprofit called the Ocean Cleanup and reaching out to it.. At the time, the group was focused on cleaning up the Amazon River.. Kalmick later learned from reporting about an interceptor installed in Ballona Creek. between Playa del Rey and Marina del Rey. and that example pushed him to widen the circle of stakeholders.
A few months after he began contacting officials. Assemblymember Diane Dixon. a Republican representing coastal Orange County. helped create the San Gabriel River Working Group.. Feasibility studies for the San Gabriel and Los Angeles river projects are now complete. officials said. and the Ocean Cleanup has agreed to participate.
Even with that progress, the path to installation is not straightforward. Organizers said the project still depends on permits from numerous government agencies, a reminder that environmental solutions in a major metro area often hinge as much on bureaucracy as on engineering.
The stakes are not only about litter on beaches.. Stakeholders also pointed to a small population of green sea turtles living in a brackish area near the mouth of the San Gabriel River. a detail many Angelenos. they said. are unaware of.. Organizers emphasized the need to protect roughly 100 turtles as the project advances.
Trash can ensnare the animals. One rescued turtle, nicknamed Porkchop, was released into the river last year after a fishing line severely constricted one flipper. The Aquarium of the Pacific in Long Beach rehabilitated her and is currently caring for another turtle found anchored to debris.
This one is a 200-plus-pound turtle named Meatloaf, which suffered a flipper injury. Cassandra Davis, director of volunteer services for the aquarium, said staff are using therapies to support healing and described a routine of regular care.
“Our vet staff is using some really amazing therapies to help her with that healing,” Davis said. “She undergoes basically a spa treatment every Tuesday.”
Organizers said the interceptor would have to be placed carefully so it does not harm wildlife. James Patterson, who oversees Ocean Cleanup operations in Los Angeles, said the nonprofit is reviewing research from the aquarium and the National Oceanic and Atmospheric Administration to guide the plan.
“At every step of the way, these sea turtles are being considered,” Patterson said.
The devices themselves are designed to work quickly when rainfall turns waterways into highways for debris.. After the news conference. Patterson led reporters to see a working interceptor on Ballona Creek. where a model installed in 2022 carries the name 007.. From a nearby onshore path. it may not look like much. appearing like an oddly shaped structure with an arm of floaties extending toward a rocky shoreline.
When precipitation is forecast, divers are called out to attach a barrier at the other side of the creek.. The barrier forms a funnel, guiding trash toward the interceptor.. As the river flows. a conveyor system captures the material. which is then dumped into six bins at the center of the vessel.. Once the bins reach capacity. estimated by officials at about 20. 000 pounds. a boat hauls the trash to the harbor and a crane lifts it out in nets.
Since the 2022 installation, officials said, the interceptor has collected more than 200 tons of trash.
Patterson cautioned that 007 is not a one-size-fits-all solution. Different waterways require different arrangements, he said. The challenge in Los Angeles and the San Gabriel River, he said, is the volume of trash moving through them.
“One of the challenges with the L.A. River and San Gabriel River is the sheer volume of trash” flowing down, Patterson said. “We need a good extraction method that can actually pull trash out in a rapid amount of time.”
He said the best design for these rivers may be one that transfers trash directly to shore. The Ocean Cleanup is examining that approach.
The costs for each interceptor are expected to be steep. Public works officials estimated upfront costs between $5 million and $8 million per device, with ongoing operation costs up to about $3 million to $4 million per year. Los Angeles County would cover operations.
The timetable is set to align with a moment when attention will be focused on the Los Angeles region.. Long Beach is scheduled to host Olympic events including open-water swimming, rowing and sailing.. Organizers described the lead-up to the Games as an opportunity to make sure the coastline looks its best. not just in headlines but in real conditions for visitors and residents.
“Just as the sporting event has spurred upgrades of museums and the Metro, it’s an impetus to make sure the beaches are camera-ready,” Long Beach Mayor Rex Richardson said.
“We want to make sure we present the very best of Los Angeles and Long Beach, and that includes a cleaner, healthier, more beautiful coastline,” he added.
