A platform for research: civil engineering, architecture and urbanism
Little River Inlet Navigation Project, Brunswick County, North Carolina and Horry County, South Carolina. Revision
The recommended plan of improvement consists of the following: dredging an entrance channel, 300 feet wide and 12 feet deep through the offshore bar, a distance of approximately 5,160 feet; providing an inner channel, 90 feet wide and 10 feet deep from the entrance channel to the Atlantic Intracoastal Waterway, a distance of 11,000 feet; dredging the lower 5,200 feet of the inner channel; dredging an upcoast deposition basin adjacent to the weir section of the north jetty to a depth of -20 feet to provide a capacity of 200,000 cubic yards; constructing a north jetty 3,385 feet long with a low weir section for sand bypassing; constructing sand dikes on both sides of the inlet to tie the jetties to the existng dune line; and possibly constructing a fishing walkway on top of the south jetty. The adverse environmental effects will be temporary increase in turbidity; alteration of existing vegetation during construction of south sand dike; temporary disturbance of birds and mammals in the area; destruction of some benthic organisms by dredge cutterhead; smothering of invertebrates under jetty stone and in beach disposal area; and possible displacement of wildlife species.
