Rye Harbor Maintenance Dregding

The Rye Harbor FNP consists of: a channel 100 feet wide by -10 feet deep MLLW from deep water northwesterly 600 feet through the entrance (between two breakwaters) then at -8 feet deep MLLW for 1,700 feet within the harbor; two 5-acre anchorages, one -8 feet deep MLLW south of the channel and the other -6 feet deep MLLW north of the channel. Work will also include dredging of the -8 feet deep State anchorage. The proposed work consists of dredging approximately 60,000 cubic yards (CY) of a mix of fine sand and silty material from shoaled areas Federal channels and anchorages. All areas of the FNP will be dredged to the authorized project depth, plus one foot allowable overdepth. A mechanical dredge will be used to remove material from the shoaled portions of the channels/anchorages, and dredged material will be transported in scows for placement at either the Cape Arundel Disposal Site (approximately 22 NM away) or the Isles of Shoals North Disposal Site (approximately 12.5 NM away). The anticipated allowable dredging window is between November 15 and March 15. Additional work includes removal of derelict moorings as necessary. In order to accomplish all dredging requirements within the specified dredging window the Contractor will need to meet a production rate of 25,000 CY per 30 calendar days. Environmental coordination and permitting has been completed by the U.S. Army of Engineers, New England District.
