Port of Long Beach dredging project on the way

The U.S. Army Corps of Engineers Los Angeles District has prepared a Final General Conformity Determination for the proposed Port of Long Beach Deep Draft Navigation Project.

The purpose of the proposed project is to identify, evaluate, and improve existing navigation channels within the Port of Long Beach to improve conditions for current and future vessels.

The project is located at Port of Long Beach Federal channels and berths serving Pier J and Pier T/West Basin.

The project will deepen existing Federal channels and constructs a new Federal channel and turning basin by dredging and disposing up to approximately 7.4 million cubic yards of sediment.

According to the Corps, construction is expected to begin in 2024 with approximately 39 months needed to complete the works.

The proposed project, which will be undertaken jointly by the USACE and the POLB, is set to deepen the entrance to the Main Channel (the Approach Channel through Queens Gate) to a depth of -80 feet (ft) mean lower low water (MLLW), widen portions of the Main Channel (bend easing) to a depth of -76 ft MLLW, construct an approach channel and turning basin to Pier J South to a depth of -55 ft MLLW, and deepen portions of the West Basin and West Basin Approach to a depth of -55 ft MLLW.

The POLB also plans to deepen two additional locations within the harbor to a depth of -55 ft MLLW: the Pier J Slip, including berths J266-J270, and berth T140 on Pier T. Structural improvements will also be performed on the Pier J breakwaters at the entrance of the Pier J Slip to accommodate deepening of the Pier J Slip and Approach Channel to -55 ft MLLW.
