- Business & Finance
The U.S. Army Corps of Engineers, New England District, is proposing to perform maintenance dredging of the Hampton Harbor Federal navigation project in Seabrook and Hampton, New Hampshire, and the state anchorage in Hampton.
The proposed work involves maintenance dredging of the 8-foot Mean Lower Low Water (MLLW) anchorage on the Seabrook side, the 8-foot and 6-foot MLLW anchorage areas on the Hampton side, and the 8-foot MLLW inner channels connecting both areas with the entrance channel, plus an authorized 1 foot of overdepth, in the Hampton Harbor FNP.
Additionally, the proposed work involves maintenance dredging of the state of New Hampshire’s 6-foot MLLW anchorage, plus authorized overdepth.
“Maintenance dredging of approximately 150,000 cubic yards of sandy material from the authorized project area will maintain the Federal Navigation Project and state of New Hampshire Anchorage to required and authorized dimensions,” said Project Manager Ms. Coral Siligato, of the Corps’ New England District, Programs/Project Management Division in Concord, Mass.
Dredging will be conducted with a hydraulic dredge, hopper dredge, or combination of the two. The state’s maintenance project involves dredging approximately 2,500 cubic yards of sand from the upper 6-foot anchorage area in Hampton.
Construction activities involving hydraulic dredging will be performed during a five-month period between Oct. 1 and March 15. Dredging of the inner harbor would be performed between Oct. 15 and Feb. 1, dredging and placement activities in the entrance channel would occur between Oct. 15 and March 15, and work on the receiving beaches would occur between Oct. 1 and March 15.
In the event that the government-owned hopper dredge performs work in Hampton Harbor, the work would be limited to the entrance channel and would occur between May 1 and July 31, of the year in which the work takes place.
The work is currently anticipated to be performed in 2019/2020.
