The U.S. Army Corps of Engineers’ Los Angeles District has received a permit application from the City of Redondo Beach, California, for the proposed King Harbor Maintenance Dredging project.
According to the Corps, the King Harbor project calls for maintenance dredging at two different areas.
Dredging Area I is the shoal fronting the north portion of King Harbor North Breakwater. Dredging Area II is the shoal fronting the inner portion of South Breakwater at the entrance of Basin 3.
The proposed depth for Dredging Area I is -18 feet MLLW and the approximate dredging area is 4.1 acres. The proposed depth for Dredging Area II is -15 feet MLLW, with dredging area of approximately 0.35 acre.
In total, the estimate dredging quantity for the two dredging areas is 46,300 cubic yards (cy) to the design depth. However, with a 2-foot OD allowance, the estimate dredging quantity for the two areas comes to approximately 62,000 cy.
Due to the location and area being dredged, the applicant is planning to use mechanical or hydraulic dredge equipment.
