Scusset sand transport to be expensive

The long-proposed sediment dredging at the Scusset Beach Basin north of the canal will be costly, Sandwich Town Manager Bud Dunham told selectmen last week.

The town wants to dredge sediment and transport it to Town Neck Beach, which is suffering from erosion and needs to be renourished.

Dunham said the Woods Hole Group, performing subcontract technical work for the Army Corps of Engineers on that agency’s federal Section 1-11 study into east end canal jetties impacts, has provided transport estimates.

He said the project figures, which come from the Cashman Dredging and Marine Contracting Co. of Quincy and Great Lakes Dredge and Dock Co. of Illinois, range from $8.5 million to $10 million.

Dunham remains optimistic the Army Corps will ultimately determine that the canal jetties interrupt the littoral drift of sediment along Cape Cod Bay with sand accumulating off Scusset. Optimism aside, tapping the Scusset basin has been municipally frustrating and time-consuming when it comes to securing approval, he said.

State environmental authorities support basin dredging, but the Army Corps still has not afforded Sandwich a sand-bypass final permit to tap and transport Scusset sediment. And a $10 million transport project cost might near the $15 million mark, Dunham said.
