Oceanside beaches are expected to receive about 380,000 cubic yards of sand from the harbor this fall as officials test a new dredging schedule designed to strengthen the shoreline ahead of winter.
The U.S. Army Corps of Engineers, in consultation with the city, is moving this year’s dredging to fall in an effort to improve beach resilience heading into winter, according to a city announcement. The Corps retains the option of returning to a spring schedule in future years.
City officials said the experiment is intended to take advantage of winter wave patterns, which could gradually redistribute newly placed sand toward heavily eroded stretches farther south. A wider beach could also provide additional protection for coastal infrastructure and recreational areas during what forecasters expect could be a strong El Niño winter.
The dredging also serves a second purpose: maintaining safe vessel navigation through the Oceanside Harbor inlet. Shoaling since the Army Corps’ previous dredging operation in May has reduced the channel’s safe navigable depth, according to the city.
Equipment mobilization began Sept. 12, closing Harbor Lot No. 12 at the end of the harbor for the duration of the project. Initial sand placement was expected to begin around Sept. 15, reach the vicinity of the Oceanside Pier by about Sept. 18 and then continue south toward Tyson Street Park, depending on weather and ocean conditions.
The overall operation is expected to continue until about Oct. 20. City officials are asking beachgoers to use caution around heavy equipment, staging areas and marked access routes during the work.
The dredging also will overlap with other construction along Oceanside’s waterfront this fall.
Bracing work on the fire-damaged Oceanside Pier’s hammerhead is scheduled to begin in October, while the second phase of the Downtown Water and Sewer Replacement Project will continue along the Strand. Heavy equipment associated with the Strand project will restrict North Strand to residents and emergency vehicles, according to the city.
