The applicant proposes to dredge a 952 feet by 30 feet wide access channel to a depth of -4.0 ft.@ MLW, of which 750 linear feet was previously dredged, from the AIWW extending to a 60 feet long by 160 feet wide boat basin at the existing private docking facility (also to be dredged to a depth of -4.0 MLW). The proposed maintenance dredging would extend approximately 202 linear feet beyond the original dredge footprint within Outstanding Resource Waters (ORW) adjacent to the AIWW. Dredging would occur by a "bucket to barge" excavator. The proposed box cut from this dredging would result in approximately 38,160 sq. ft. of shallow bottom excavation. No wetlands are indicated within the limits of the proposed dredging. Approximately 2200 cubic yards of dredged spoil material will be deposited on an upland spoil disposal island (DA 228), which is located outside the ACOE Placement Areas and owned by the Northeast New Hanover Conservancy Spoil Island. The applicant has obtained written authorization from the owner of the spoil disposal island for this placement. The Federal agencies have completed review of the proposal as presented by the application and your field investigation report. We recommend that the following conditions be included in the State authorization: SPECIAL CONDITIONS 1.

This permit does not authorize temporary placement or double handling of excavated or fill material within waters outside the permitted area. 3. Work in wetlands are prohibited during the dredging, use of the disposal island or any other aspect of work associated with this project. 4.
