| dc.description.abstract | The U.S. Army Corps of Engineers (USACE), Jacksonville District proposes to dredge the St. Lucie Inlet entrance channel, and impoundment basin, any time of the year and on an “as-needed” basis in order to maintain safe navigation in the channel. The work would consist of routine operations and maintenance (O&M) 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 9,200 feet. The impoundment basin is 450 feet by 2,500 feet and will be dredged to a required depth of 13 feet. Shoal material will be placed either in the 10,000-foot nearshore disposal area located approximately 10 miles south of St. Lucie Inlet between State Monuments R-89 and R-99, in a previously used beach disposal area located 4,000 feet south of the inlet and extending for 10,000 feet further south; and/or within a 562 acre offshore disposal area identified as “Borrow Area B” (Figure 3). This borrow area is located offshore Jupiter Island, approximately between R-109 and R-118 as depicted in Figure 1 and Figure 2. Use of Borrow Area B would allow for storage of dredged material that may be utilized by others for future nourishment/renourishment events. The frequency of use of the offshore disposal site would coincide with the maintenance dredging frequency of every three to five years or as needed due to weather related shoaling. If material is not placed in Borrow Area B, the staging areas developed as part of the Peck’s Lake placement shall be utilized for beach renourishment. | en_US |
