Marina del Rey Dredging Project Details

Marina del Rey, California—The U.S. Army Corps of Engineers (USACE) is set to initiate a vital dredging project in Marina del Rey's harbor. The Los Angeles County Department of Beaches and Harbors has confirmed that the project will commence as planned.

The Sea Horse dredge vessel will be employed to remove 400,000 to 500,000 cubic yards of sediment from the Marina's entrance and the harbor's north jetty. This accumulation, equivalent to approximately a hundred Olympic-sized swimming pools, poses navigational challenges for boaters and first responders.

The five-month maintenance dredging effort aims to address shoaling issues along the north jetty, enhancing safety and accessibility. Operations by the Sea Horse, equipped with a clamshell bucket, will begin following necessary equipment inspections.

During dredging, the removed sediment will be loaded onto the Robert L dump scow and deposited in the Pacific Ocean nearshore of Dockweiler State Beach, just north of Imperial Highway in Playa del Rey. The Robert L is expected to make approximately four to five trips per day for efficient sediment disposal.

While dredging is underway, certain portions of the harbor entrance may become temporarily impassable. Boaters are encouraged to stay informed about accessibility conditions through the Department of Beaches and Harbors (DBH) social media sites or by contacting Harbormaster Sgt. Ron Nohles at; 310-482-6000 (Office); 323-893-6803 (Cell).

With a budget of $7.18 million funded through Federal Budget appropriations, this dredging project is essential for maintaining safe navigation for the U.S. Coast Guard, first responders, and the approximately 4,300 recreational vessels docked in Marina del Rey.
