Full Public Notice Project Plans
The applicant proposes to amend the existing dredging
permit by adding the following components:
expansion of dredging area and depth; performing work, including
demolition of existing structures; installation of a sheet pile bulkhead,
installation of articulated concrete mat; construction of a dock and
appurtenances; mooring berthing dolphins; and performing other activities in
uplands. Specifically, the proposed
project includes the following components:
existing structures over waters of the U.S. including various buildings, paved
areas, and fencing; an existing 320-foot dock; three dry docks; and
920-linear-foot existing bulkhead.
1,193 linear feet of dock, including the maximum extent of mooring dolphins.
approximately 431,000 cubic yards from 2.2 acres of upland area and convert to
of a 9.2 acres berthing area to 47 feet below mean low tide (MLT). Dimensions of the currently authorized dredge
area for Dock 42 would be extended by 8.9 acres.
in waters of the U.S. will be accomplished by hydraulic cutter suction dredge
or mechanical dredge.
dredged material is proposed to be disposed of at Shoal Point Terminal Dredge
Material Placement Areas (DMPA)
Maintenance dredging: Based on
average shoaling rates of dredge areas in the vicinity, and with similar
configuration, the annual maintenance volume is estimated to be 12,800 cubic
yards of dredge material. The Shoal
Point Terminal DMPA’s have been authorized for placement under the previous
Installation of 840 linear feet of steel sheet pile bulkhead along the
proposed shoreline. No material is
proposed for backfill along this bulkhead.
Installation of 45,000 square feet of articulated concrete mat in front
of the bulkhead to prevent erosion along the bulkhead. The proposed bathymetry along the bulkhead
has been revised to include a 5’ horizontal span before sloping (3H:1V) to the
project depth of -47 MLT.
The dock and associated mooring dolphins, as measured
above, would extend 946 feet beyond the south facing bulkhead, or MHW. The total surface area is described in the
Dredge volumes and associated footprint are provided in
