After a long wait, the dredge of Mianus Channel has begun. On Wednesday it was possible to watch the work underway from the Dave Theis Bridge connecting Cos Cob to Riverside. According to Harbor Master Ian MacMillan, Patriot Marine is removing 6,000 cubic yards of “the worst of the material.”

MacMillan said that they’ll remove material to a depth of 7 ft and span a width of 100 ft.

“They want to put it in western Long Island Sound first so that they can bury it with the clear dredge they remove from the Mianus channel,” MacMillan said.

The federal navigation project (FNP) contract is with Patriot Marine, and they will remove 1,000 cubic yards a day, which MacMillan estimates will take two to three months, depending on weather conditions.

    Hope this is the last dredge ever using the outdated,expensive & wasteful techniques.
    Using the latest modeling techniques, scientists from the conservation, engineering and insurance sectors studied the impact of Hurricane Sandy in the Northeast United States in 2012, when New York and New Jersey were badly hit by storm surges.
    The study found more than $625 million in property damages were prevented during this natural catastrophe by coastal wetlands along the Northeast coast.
    Without wetlands, the damage bill would be much higher for Sandy and other predicted hurricanes. Where wetlands remain, the average damage reduction from Sandy was greater than 10 percent.
    GREENWICH TOWN PLAN incorporates these findings.
