Abstract: The U.S. Army Corps of Engineers proposes to dredge the St. Lucie Inlet entrance channel and impoundment basin in order to maintain safe navigation in the channel. The work would consist of routine maintenance dredging of an estimated 400,000 cubic yards of sand from portions of the entrance channel and impoundment basin as needed. The channel is 300 feet wide and 18 feet deep, tapering to 150 feet wide and 12 feet deep and then to 100 feet wide and 9 feet deep. The approximate length of the project is 9200 feet. The impoundment basin is 450 feet by 2500 feet and will be dredged to a required depth of 13 feet. Shoal material will be placed either in a newly proposed 10,000-foot nearshore disposal area located approximately 10 miles south of St. Lucie Inlet between State Monuments R-89 and R-99 or in a previously used beach disposal area located 4,000 feet south of the inlet and extending for 10,000 feet further south. It is to be decided which disposal area will be used, depending on the season during which the dredging and disposal activity is to take place, in order to avoid impacts to endangered and threatened species (ie. manatees, sea turtles, sea grasses, etc.).
