Oceanside’s Small Craft Harbor District has sued the U.S. Navy, seeking at least $378,688 for damage it blames on sediment-laden stormwater from Camp Pendleton during storms in January 2024. The lawsuit alleges sediment-laden stormwater from Camp Pendleton flowed into Oceanside Harbor during the storms.
The suit names the U.S. Navy as a defendant, according to the San Diego Union-Tribune. Oceanside alleges sediment-laden stormwater from Camp Pendleton damaged the harbor. The city is seeking recovery for damage.
Sediment Still Clogging the Channel
According to the lawsuit, the sediment accumulation has inhibited navigation, berthing, slip usage and docking activities throughout the harbor.
Camp Pendleton officials did not respond to a request for comment on the lawsuit, the newspaper reported.
A Harbor Already Buried in Sand
The lawsuit lands amid a long-running struggle to keep Oceanside Harbor’s channel navigable. The city manager declared a local emergency over sand buildup on Nov. 18, 2025, and the City Council later ratified that declaration unanimously, the Union-Tribune reported at the time.
Oceanside sought an early dredge, and the Army Corps of Engineers was working to move the 2026 dredge date up to as early as March.
A January 2026 report from KPBS found sand buildup had cut the depth at the harbor’s mouth to between 7 and 14 feet, far short of the ideal 30-foot depth. The outlet noted the Corps declined Oceanside’s emergency dredge request after determining the harbor remained navigable, and that the Corps was working to move the 2026 dredge date up to as early as March, after typically dredging the harbor each spring around April.
City Pushes for a Fall Dredging Schedule
Oceanside’s annual dredging schedule has shifted from spring to fall. The city’s harbor dredging page confirms the 2026 operation served as a trial run of the adjusted fall timetable, meant to restore depth that had narrowed since the Corps’ last dredge in May 2026. That fall project was expected to remove roughly 380,000 cubic yards of sand from the channel.
The scale of the problem has grown over the years. During the 2024 dredging cycle, which began the week of April 22 and wrapped up by June 4, crews removed 266,000 cubic yards of material from the channel, placing more than 150,000 cubic yards of it on Oceanside beaches south of the pier, according to a city update at the time. Separately, Oceanside and Camp Pendleton have worked together over the past year to explore improved access to the Capistrano residential neighborhood, located just east of Interstate 5 near the base’s main entrance.
