Innovative Solutions to the Disposal Challenge: Beneficial Reuses of Dredged Material for the Pier T Marine Terminal Port of Long Beach, California

The Pier T Marine Terminal is a new 375-acre (152-hectare) container terminal being developed by the Port of Long Beach at the site of the former Long Beach Naval Complex. Development includes demolition of an extensive array of upland and in-water facilities, import of fill material, site grading, and construction of new utility systems and container terminal facilities. In-water improvements in the West Basin include dredging the approach channel, turning basin, and berths to a minimum depth of -50 feet (15.2 meters) mean-lower-low-water, and construction of an approximately 20-acre (8-ha) landfill for the intermodal rail yard, a rock revetment slope, and a 5,000-foot (1,520 m) deep-draft concrete wharf. Phased project dredging includes removal of nearly 2.3 million cubic yards (1.8 million cubic meters) of clean sediments and over 3 million cy (2.3 million cm) of sediments unsuitable for unconfined aquatic disposal because of chemical contamination. Project planning and permitting emphasized reuse of dredged material as much as possible in order to support Pier T construction and other Port terminal improvements and to provide appropriate disposal of unsuitable sediments.
