9. Project Description
The project is located along the waterward face of the existing wharf, Berths 1 - 9, of the N. C. State Ports
Facility (NCSPA), adjacent to the Cape Fear River, in Wilmington, in New Hanover County. The State
Ports Facility tract consists of 334 acres, and the port infrastructure was constructed between 1950 and 1972
to serve as a transport shipping terminal. The facility currently includes nine (9) ship berths which facilitate
operations for container transport, bulk products and wood pulp shipping, as well as; military supplies, steel
sheeting, and miscellaneous supplies and cargo. The shoreline is stabilized by approximately 6800 linear feet
of bulkhead adjacent to the Cape Fear River, and a pile supported, concrete hardstand or wharf extends into
the river to the berth areas. The wharf is accessible by rail, as well as, vehicular traffic and currently
supports the operation of two (2) container cranes, bulk products hopper system (under construction) and a
wood chip conveyor system. The Ports Authority currently holds State Permit #47-87 which authorizes the
maintenance dredging of the shipping basin and other activities around the port.
The waters of the Cape Fear River are classified SC by the NC Division of Water Quality. They are
designated as Primary Nursery (PNA) by the NC Division of Marine Fisheries. There is no shellfish
resource. The Wilmington/New Hanover County Land Use Plan classifies the upland area as Developed.
Prior to the deepening of the berth areas, in conjunction with the deepening of the federal channel
(Wilmington Harbor Project), the NC State Ports Authority (NCSPA) proposes to modify their existing
permit to authorize the construction of a toe wall along the waterward face of the existing wharf to stabilize
the sediment deposits that have, over the years, accumulated beneath the hardstand. (The NCSPA
commissioned a stability study which recommends a toe wall system that would allow the deeper dredge
depths, and would eliminate the need to remove the sediment build-up around the existing hardstand's piling
configuration.) Two types of toe walls are proposed. At Berths 1 -4, a king pile toe wall would be installed.
This system incorporates the use of steel H-pilings, approximately 6 feet on center, with interlocking steel
sheet piling between each H-piling. The king pile toe wall adjacent to Berths 1 - 4, would be 2795 feet in
length and average 11 feet in height above the new basin depth of -42 feet at mean low water. At Berths 5 -9,
an interlocking steel sheet pile toe wall is proposed. This wall accomplishes the same functions, but does not
require the steel H-pile reinforcement. The sheet pile toe wall adjacent to Berths 5 - 9, would be 2265 feet in
length and average 7 feet in height above the new basin depth of -42 feet at mean low water. Additional work
associated with this project would include the replacement of the curbing along the front face of the existing
hardstand and the replacement of the docking bollards at Berths 7 and 8. The installation of the new toe wall
would also require the modification of the existing fender system to extend the docking fenders beyond the
toe wall alignment.
10. Anticipated Impacts
There will be no change in the use of the State Ports Authority's facilities. The installation of the toe wall
project would incorporate approximately 20,100 square feet of river bottom within the State Ports basin.

Dear Mr. Br
The North Carolina State Ports Authority (NCSPA), Port of Wilmington is
requesting a modification to CAMA Major Permit No. 47-87, expiration date 12-31-02. This
modification will allow the Port of Wilmington to perform repairs and upgrades to Berths 1
through 9 in preparation of the Corps of Engineers deepening of the Wilmington Harbor.
The proposed project elements including toe walls, fendering and hardware
refurbishment are all in conjunction with the Wilmington Harbor Project. The toe wall systems
will serve multiple functions of allowing the deeper dredge depths, maintaining the current
berths piling configuration and eliminating the need to remove the sediment build up behind the
facility's dock structures. The installation of the toe walls below mean low water will not disturb
any uplands or tidal wetlands.
The North Carolina State Ports Authority, Port of Wilmington is requesting a
modification to the existing CAMA Permit No. 47-87. This modification will permit the
installation of a steel sheet pile toe wall allowing the safe operation of Berths 1 through 9 at the
Wilmington Harbor dredge depth of -42' MLLW. Attached is a detailed transmittal, completed
application, riparian notifications, associated drawings and the application processing fee of
$400.00. If additional information is needed or questions arise, please call me at [phone].

Re: North Carolina State Ports Authority
Berth Repairs and Upgrades, Berths 1 - 9
Accommodating -42' MLLW Dockside Depths
Port of Wilmington
Dear Mr. Brooks:
The North Carolina State Ports Authority (NCSPA) is requesting a modification to the Division
of Coastal Management (DCM) Major Permit No. 47-87, expiration date 12-31-02. This
modification will allow the Port of Wilmington to perform repairs and upgrades to Berths 1
through 9 in preparation for the Corps of Engineers deepening of the Wilmington Harbor. The
Corps of Engineer's Harbor Project will result in inner harbor navigational channel depths of -42'
MLLW with F of required overdredge in rock areas and an additional 2' allowable throughout
the project area.
In response to the channel deepening, the NCSPA is preparing to accept the new channel dredge
depth at the face of Berths 1 through 9. To accomplish this, the Port commissioned a study of
the stability of the existing berths at an EL -42' MLLW dredge depth. This study indicated that
Berths 8 and 9 are presently capable of being dredged to EL -42' MLLW without any structural
improvements. Berths 1 through 7 however do require modifications to allow dredging to EL -
42' MLLW. The NCSPA is presently preparing plans and specifications for the repair and
upgrade of Berths I through 9 at the Wilmington Terminal, see Figure 1. Moffatt & Nichol
Engineers has been selected to perform the design work.
The proposed approach to upgrade Berths 1 through 7 is to install an underwater steel sheet pile
cutoff wall. The toe wall systems will serve multiple functions in allowing the deeper dredge
depths, maintaining the current berths' piling configuration and eliminating the need to remove
the sediment build up behind the facility's concrete pile configuration. Two types of cutoff wall
are proposed. The first type, provided for Berths 1 through 4, is a king pile toe wall, see Figures
2, 4, and 6. This type of wall consists of steel HZ575 piles with intermediate AZ13 steel sheet
piles. The King Pile Toe Wall will consist of steel HZ King Piles driven into the river bottom's
rock strata. The King Piles will be spaced at approximately 6 feet 2 inches center-to-center with
intermediate AZ steel sheet piles installed between the king piles. The intermediate sheet piles

do not provide any lateral resistance to the wall, but they do serve to distribute the lateral earth
pressures to the king piles.
The second type of cutoff wall, provided for Berths 5 through 7 and 26'-6" of Berth 8, consists
entirely of AZ13 steel sheet piles, see Figures 3, 5, and 7. This wall functions in exactly the
same fashion as the previously described wall but does not require the HZ-pile. The steel sheets
can be driven to adequate embedment to allow them to transfer all the lateral load directly into
the underlying soils. These sheets are capable of reaching the required embedment length due to
the fact that the hard cemented sand layer generally slopes from a higher elevation at Berth 1 to a
lower elevation at Berth 9.
With the installation of the underwater cutoff walls, the fender systems must be modified to
minimize the likelihood of ship impact with the cutoff wall. As such, new concrete fender panels
are to be constructed onto which will be mounted either new or existing fender elements. Each
fender panel will be supported by two new 14 inch square precast prestressed concrete piles.
The piles will be driven under the existing berths and behind the new steel sheet pile cutoff wall.
The new concrete fender panels will project approximately 2'-6" beyond the front face of the
wharf. This distance, in conjunction with the fender elements, will be large enough to minimize
the potential of an impact between the underwater cutoff wall and a ship during berthing
operations. New concrete fender panel build-outs will also be provide for the full length of
Berths 8 and 9. This is necessary in order to maintain a consistent fender alignment along Berths
7, 8, and 9 in light of the fact that Berth 7 requires a new toe wall.
Additional work associated with this project will include the removal of timber curbing along the
front face of the wharf and replacement of this curbing with fiberglass reinforced plastic timbers.
These timbers will not rot and will be UV rated so as not to deteriorate in direct exposure to
sunlight. In addition, the bolts and plate washers associated with the mooring hardware along
the front face of the wharf will be removed and replaced. The cleats and bollards will also be
cleaned and painted. Finally the bollards on Berths 7 & 8 will be removed and replaced with
new bollards due to insufficient strength on the part of the existing bollards to carry the loads
associated with the larger ships, which may call at the Port of Wilmington. There will be no
utility work associated with this project.
The proposed project elements including the toe walls, fendering and hardware refurbishments
are all in conjunction with the Wilmington Harbor Project. The proposed efforts are within the
scope of the previously submitted environmental documentation meeting both the National
Environmental Policy Act (NEPA) and the State Environmental Policy Act (SEPA). The
following are excerpts, from the US Corps of Engineers' document, "Final Feasibility Report
And Environmental Impact Statement On Improvement Of Navigation" Volume One, June 1996

the improved channel. The principle construction item will be dredging and
bulkhead modification at the State Ports Authority docks."
The installation of the toe wall will not disturb any upland or tidal wetlands triggering the need
for an erosion control or stormwater permit. Good engineering practices will be implemented
throughout the project to assure responsible construction techniques and oversight.
The North Carolina State Ports Authority, Port of Wilmington is requesting a modification to the
existing CAMA Permit No. 47-87 allowing the installation of a steel sheet pile toe wall to allow
the safe operation of Berths 1 through 9 at the new Wilmington Harbor dredge depth of -42'
MLLW. The toe wall systems will serve multiple functions of allowing the deeper dredge
depths, maintaining the current berths' piling configuration and eliminating the need to remove
the sediment build up behind the facility's concrete pile configuration. Attached are the

Item 3: Description and Planned Use of Proposed Project
d. Give a brief description of purpose, use, methods of construction and daily
operations of proposed project.
The proposed approach to upgrade Berths 1 through 7 is to install an underwater steel sheet pile
cutoff wall to retain the active side soils and concrete piles associated with the wharf structure.
Installation of the toe wall will permit dredging to EL -12.0 (MLLW) along the dock face at the
Port of Wilmington. Berths 8 and 9 do not require a toe wall to accept the increase dredge depth.
Two types of cutoff wall are utilized. The first type, provided for Berths 1 through 4, is a king
pile toe wall. This system will be installed 9 inches in front of the existing front face of each
berth. The King Pile Toe Wall will consist of steel HZ King Piles driven into the hard cemented
strata.
The second type of cutoff wall, provided for Berths 5 through 7 and 26'-6" of Berth 8, consists
entirely of steel sheet piles. This wall functions in exactly the same fashion as the previously
described wall but does not require the HZ-pile as the steel sheets can be driven to adequate
embedment to allow them to transfer all the lateral load directly into the underlying soils.
With the installation of the underwater cutoff walls the fender systems must be modified to
minimize the likelihood of ship impact with the cutoff wall. As such, new concrete fender panels
are to be constructed onto which will be mounted either new or existing fender elements. Each
fender panel will be supported by two new 14 inch square precast prestressed concrete piles. The
piles will be driven under the existing berths and behind the new steel sheet pile cutoff wall. The
new concrete fender panels will project approximately 2'-6" beyond the front face of the wharf.
This distance, in conjunction with the fender elements, will be large enough to minimize the
potential of an impact between the underwater cutoff wall and a ship during berthing operations.
New concrete fender panel build-outs will also be provided for the full length of Berths 8 and 9.
This is necessary in order to maintain a consistent fender alignment along Berths 7, 8, and 9 in
light of the fact that Berth 7 requires a new toe wall.
Additional work associated with this project will include the removal of timber curbing along the
front face of the wharf and replacement of this curbing with fiberglass reinforced plastic timbers.
The cleats and bollards will also be cleaned and painted. Finally the bollards on Berths 7 & 8 will
be removed and replaced with new bollards due to insufficient strength on the part of the existing
bollards to cant' the loads associated with the larger ships, which may call at the Port of
Wilmington. There will be no utility work associated with this project.
Item 4: Land and Water Characteristics
a. Size of entire tract
The area for the entire tract (20,280 square feet) includes the total length of Berths 1 through 9
(6700 feet) and the width from the face of the wharf to the outermost waterside face of the steel
toe-wall (3 feet).
