H&L Contracting, LLC of Bay Shore, NY, has won a $4.4 million maintenance dredging contract for the Hampton Harbor project in New Hampshire.
According to the Army Corps, dredging and disposal operations are anticipated to take about 4 to 5 months to complete and will occur between Oct. 15, 2019 and March 1, 2020.
During the project, approximately 150,000 cubic yards (CY) of sandy material will be hydraulically dredged from the 8-ft channel, and three 6-ft anchorages at the mouth of the river and material pumped onto adjacent beaches in Hampton and Seabrook, NH.
This work will allow project users to maintain safe navigation in Hampton Harbor. Natural shoaling processes have reduced available depths to as little as 1.0 foot in the 8-foot MLLW channel in Seabrook and 8-foot MLLW anchorage in Hampton, as little as 2.5 feet in the 8-foot Seabrook Anchorage, and approximately 4.0 feet in the 8-foot MLLW cross channel, 6-foot MLLW Hampton Anchorage and 6-foot state of New Hampshire Anchorage making navigation hazardous or impossible at lower stages of the tide.
An optional bid item is included in the contract to hydraulically dredge approximately 2,500 cubic yards of sandy material from the state anchorage in Hampton with placement on Hampton State Beach.
