Gulfport Harbor, Mississippi. Final Environmental Impact Statement
Abstract
The recommendation included the modification of the existing harbor dimensions, realignment of the channel through Ship Island Pass, and the construction of a deposition basin for littoral drift at the west end of Ship Island. A total of 23.79 million cubic yards of material would be removed during construction of the project; 8.15 million by hopper dredge for disposal in the Gulf of Mexico; and 15.64 million cubic yards would be deposited by pipeline dredge in Mississippi Sound. Two economically and engineering feasible methods were under consideration for disposal of the Mississippi Sound material: (1) placement in a thin layer over sound bottoms and (2) construction of three islands in the sound. During annual maintenance of the project, up to 3.74 million cubic yards of material would be deposited in open water on both sides of the sound channel and up to 0.44 million cubic yards would be hopper dredged in the gulf. The report recommended that authorization of Phase I design memorandum stage of advance engineering and design be accomplished rather than construction. (jhd)
