The New York District of the U.S. Army Corps of Engineers announced a contract for the provision of maintenance dredging of the Red Hook Flats Anchorage, New York Harbor, Federal Navigation Project.
The sediment from this project was tested and meets the criteria for remediation material at the Historic Area Remediation Site (HARS) and is therefore proposed to be placed at the HARS. The proposed maintenance dredging would remove up to approximately 793,000 cubic yards of sediment (approximately 104,000 cubic yards as basic work, and the remaining 689,000 cubic yards as options), subject to the availability of funds.
Dredging in the project work areas will be required to depths of 35, 40, and 45 feet below Mean Lower Low Water (MLLW) with 2 feet allowable over-depth, in their respective reaches.
The estimated range for this project is $7,5 mln and $12,5 mln.
