Review Of Reports Charleston Harbor South Carolina Text Wando River Extension Revision PDF Download

The South Carolina State Ports Authority dredged a channel 325 feet by 450 feet in the Wando River from the Charleston Harbor Federal Navigation Project to its newly constructed terminal facilities adjacent to Hobcaw Creek in the summer of 1981. This report presents the engineering, economic, and environmental studies conducted to determine the advisability of maintaining and deepening this locally-dredged channel. Since the site of the terminal facilities and channel is set, the usual technique of analyzing conditions and solutions by examining a wide range of alternatives was not considered necessary. The only alternatives were Federal adoption of the existing 35-foot deep channel and channel deepening. Based on the results of this study, it is concluded that the most economically feasible plan for satisfying future harbor needs consists of maintaining and deepening the locally-dredged channel to -40 feet mean low water datum in the Wando River. It is, therefore, recommended that the Charleston Harbor Navigation Project be modified to add the State's Wando channel to the project and to deepen this segment to 40 feet when similar depths are provided in ocean connecting reaches.
