The U.S. Army Corps of Engineers, New England District is proposing to perform maintenance dredging of the Annisquam River federal navigation project (FNP) in Gloucester, Massachusetts. The city of Gloucester is the local sponsor and requested this dredging.
The proposed work involves maintenance dredging of portions of the 8-foot-deep Mean Lower Low Water (MLLW) channel and anchorage, plus authorized overdepth dredging in the Annisquam River FNP.
“Natural shoaling processes have reduced available depths to as little as 1.0 foot in portions of the 8-foot MLLW channel and anchorage making navigation hazardous or impossible at lower stages of the tide,” said Project Manager Erika Mark, Programs/Project Management Division. “Maintenance dredging of approximately 140,000 cubic yards of sand and some gravel from approximately 20 acres of the authorized project area will restore the FNP to authorized dimensions.”
A private contractor, under contract by the government, will use a mechanical dredge and scows to remove the material and then transport it for placement at the Ipswich Bay Nearshore Disposal Site (IBNDS) and the Gloucester Historic Disposal Site (GHDS). Approximately 132,500 cubic yards of sandy material will be placed at the IBNDS and the remaining 7,500 cubic yards of sand and gravel material will go to the GHDS. Construction is expected to take between 3-4 months between Oct. 1, 2019 and March 15, 2020.
An Environmental Assessment is being prepared.
The public notice, with more detailed information, is available for review on the Corps' website at http://www.nae.usace.army.mil/Missions/Navigation/Public-Notices/. Public comments were accepted through March 6.
