Maintenance Dredging – Long Island, NY
The New York District of the U.S. Army Corps of Engineers (USACE) required maintenance dredging of the Long Island Intracoastal Waterway (LIIW) Federal Navigation Project at Moriches Bay. The proposed maintenance dredging would remove up to approximately 110,000 cubic yards (CY) of sand with placement along the shoreline of Smith Point County Park, with a 10,000 – 20,000 CY upland stockpile. The placement area is approximately 3 – 4 miles from the dredging area. Dredging would be required to a depth of -6 feet Mean Lower Low Water (MLLW) plus 2 feet allowable overdepth.
The work was performed by utilizing a hydraulic cutterhead dredge. Additionally, barges, tug boats, pipeline and land-based equipment such as dozers, were needed to perform the work during either the dredging or placement activities. The dredging and placement along the shoreline were required to meet all federal, state, and approved local criteria required by the government agencies having jurisdiction where the dredging and placement sites are located.
