Document Description
The project involves construction of a new bulkhead and fender system at Berths VII and VIII to replace the existing dilapidated bulkhead. The construction of a new bulkhead requires it to be built outside of the existing bulkhead using a combination of 62 steel king piles, 379 linear feet of sheet piles, and 51 steel batter piles. The piling will be driven in place using an impact hammer. The proposed bulkhead will extend 4 feet from the existing bulkhead to accommodate the batter pile network and the approx. 0.04-acre void between the proposed and existing bulkhead will be backfilled with 837 cubic yards of cementitious slurry. A new fender pile system will be installed on the perimeter of the proposed bulkhead for continued accommodation of tugboats and skiffs and includes 45 steel H-piles that will be driven in place using a vibratory hammer. The Applicant will provide approx. 0.04 acre of restored bay floor from the removal of existing structures and debris within the shipyard leasehold to mitigate for the loss of jurisdictional area.
