PROJECT DESCRIPTION:
Stage I of the 2020 Plan of the Port of Los Angeles (also known as the Pier 400 Project) included channel improvements to depths of 45 and 63 feet. Stage II deepened the channels to 82 feet. The project incorporated selectively dredging ten classifications of material including silts, clays, sands, mixed materials, and foundation materials, and placing these materials in the most suitable area for dike formation, specific landfill use, transportation corridor and shallow water habitat (for mitigation purposes). The project resulted in the removal of 58 million cubic yards of harbor bottom, the creation of the 590-acre landfill and the creation of 250 acres of shallow water habitat.
