A dredging contract in Mianus River

A contract for the dredging of the clogged Mianus River channel in Greenwich town is being signed.

The work includes dredging about 50,000 cubic yards of sediment from the federal channel, which has not been dredged in more than 30 years. The project must be carried out between Oct. 1 and Jan. 31 owing to environmental conditions.

The river was last dredged in 1985 which removed 53,000 cubic yards of sediment. In recent years, much silt has built up, the channel is barely passable in sections at low tide, and boats with a big draft in the water would be hitting the bottom. So the Army Corps of Engineers plans to dredge the Mianus River so that those boats can’t dock there.

The project will restore the channel to its dimensions of 6 feet deep and 100 feet wide, running from Cos Cob Harbor up the Mianus River to about 400 feet downstream of the Boston Post Road Bridge. After this dredging, the channel would be 75 feet wide. The sediment will be placed in the Western Long Island Sound Disposal Site.
