Portsmouth Navy Yard Seeks Corps Permit for Dredging

The Portsmouth Naval Shipyard is seeking a permit from the USACE, New England District, to conduct work in waters of the U.S. in conjunction with structural repairs to berths in the Piscataqua River at the shipyard in Kittery, Maine.

The proposed work involves structural repairs to berths 11, 12 and 13 of the shipyard’s dry docks including placing fill in 117,200 square feet (2.69 acres) of waterway in conjunction with the construction of a king pile and concrete shutter panel bulkhead system at berths 11, 12 and 13 and backfilling behind the bulkhead to increase the structural capacity of the piles.

The work also includes maintenance and new dredging of approximately 10,660 cubic yards of material over a 52,600 square foot (1.20 acres) area adjacent to the Dry Docks and berths 11, 12 and 13.

Dredged material that is suitable for reuse will be incorporated into the granular fill behind the bulkheads. Dredged material that is determined not suitable for reuse will be disposed of at an approved upland landfill.

The purpose of the project is to restore the crane rail support structure to allow portal cranes to operate at full capacity, extend the useful life of the existing 70-year-old steel piles, and repair deteriorated structural components.
