9. PROJECT DESCRIPTION:
The project site is located at 9 Convention Center Drive, adjacent to the Cape Fear River, in Wilmington, New
Hanover County. To find this project site from the Wilmington Regional Office, head northwest on N Cardinal
Drive Extension for 0.2 miles. Turn left onto Market Street and travel approximately 0.4 miles. Turn right onto
US -74 W/Martin Luther King Jr. Parkway and proceed 5.5 miles towards Downtown Wilmington. Continue onto
N. 3' St. for 0.2 miles and then turn right onto N Front St. Continue 0.4 miles then turn right onto Hanover St.
Travel approximately 0. 15 miles and the property will be located on the left at the end of Hanover St.
The project site is located on the east bank of the Cape Fear River and consists of a single lot with a total area of
approximately 122,404 ftz or 2.81 acres. Existing structures on this property include a concrete walkway, bulkhead
and riprap shoreline, timber boardwalk that serves as part of the Cape Fear Riverwalk, and fixed concrete pier. The
existing fixed concrete pier is 115' in length and 19.5' in width with brick topping connected to two (2) 100' in
length by 10' in width timber piers with two (2) approximately 23' diameter cellular mooring cofferdams, one at
each ends. The existing pier also includes three (3) aluminum gangways leading to a 74' in length by 11' in width
float and two (2) 70' in length by 14' in width floats. The property lies west of the Wilmington Convention Center
and 4 level parking garage owned by the City of Wilmington. The subject parcel also lies west of the new Embassy
Suites Hotel. Port City Marina lies to the north of the property, and the Greater Wilmington Chamber of Commerce
to the South. There are two adjacent public piers to the south of the existing pier off the Riverwalk with the closest
pier located approximately 50' from the southern cofferdam. The application states that project site has
approximately 635 linear feet of shoreline frontage and averages 6.5' above the Normal Water Level. The upland
area of the project site contains maintained lawn grass, an oak tree, and a few ornamental bushes. On the waterward
side of the bulkhead, within the Cape Fear River and below Normal High Water (NHW), is low marsh vegetation
consisting of common reed (Phragmites australis). The Cape Fear River is approximately 700' wide at the project
site.
The project site was previously the location of some sort of shipping terminal. The historical aerial photography
(1956 and 1966) indicates that the site contained several man-made boatslips or canals at the northern edge of the
tract, a piling supported building extending over the water and additional buildings and port related structures. The
existing pier is also seen within these photographs. Aerial photography from 1984 indicates the presence of railroad
tracks, a large storage tank, and the existing pier. In 1999, the site was cleared and graded under State Permit #91-
99 in preparation for commercial development. A pre-existing soil remediation project approved by the N.C.
Division of Water Quality — Groundwater Section was completed under Permit# SR0800073. In 2002, several
improvements proposed by Live Oak Development were authorized for this site under State Permit #15-02.
Authorized structures included, an upland extension of the City's Riverwalk, a concrete bulkhead, and changes to
the original pier which replaced the old diagonal access pier with a new straight access to the T -head and added
three floats. 7 multi -story commercial/retail and multi -family residential buildings and two additional docks were
authorized but were never built. State Permit # 15-02 was transferred to River Ventures, LLC on Jun 14, 2004 and
subsequently renewed on December 1, 2005. State Permit #15-02 was transferred from River Ventures, LLC to
City of Wilmington on June 21, 2007 and then renewed and modified on October 31, 2007. Modifications included
the construction of the convention center, parking garage, and motel, the relocation of an unbuilt pier, and the
removal of the Riverwalk decking. State Permit # 15-02 was modified again on May 12, 2008 for the installation
of stormwater outfall pipes and bulkhead repairs. Another modification was authorized on June 25, 2008 to
construct new bulkhead and extend the Riverwalk. An authorized renewal could not be located after the permit
expired on December 31, 2009, however, State Permit #15-02 was modified on January 12, 2012. Modifications
included the replacement of the two cofferdams and installation of dolphins and mooring pilings. State Permit # 15-
02 expired on December 31, 2013.
The City of Wilmington 2016 Land Use Plan classifies the highground as Central Business District the adjacent
waters of the Cape Fear River are classified SC;Sw by the Division of Water Resources. They are designated as a
Primary Nursery Area by the N.C. Division of Marine Fisheries and they are CLOSED to the harvest of shellfish.

PROPOSED PROJECT:
The applicant proposes to replace two existing pier cofferdams with steel H -piles and timber framing within the
existing footprint. The applicant states that the existing approximately 23' cellular cofferdams (steel sheetpile) will
be removed 1 ft below the mudline and the existing concrete cap will also be removed. The cofferdams will be
removed by crane on a floating barge which will be stabilized by spuds. The contractor will drive 14 new H -piles
with a pile driving attachment on the crane. Timber framing will be installed on the new steel piles to create a deck
that will connect with the existing timber T -head.
10. ANTICIPATED IWACTS:
The proposed cofferdam replacement would incorporate approximately 771.1 ft' of Estuarine Waters and Pubic
Trust Area located within the same footprint as the existing structure. The replacement would facilitate the
continued use of the pier by the public for fishing and transient boat dockage. The position of the new H -piles
would not encroach on the 15' riparian corridor of either adjacent riparian property, however, the replacement would
result in an encroachment within the Army Corps Harbor Line but would not extend any farther waterward than the
existing structures. Each existing cofferdam appears to encroach approximately 5' within the Harbor Line for a
total area of approximately MOW. Replacement of the existing cofferdams would result in the same area of
encroachment within the Harbor Line and could potentially restrict vessel navigation in the Cape Fear River. The
proposed structure would extend approximately 125' in to the Cape Fear River, which measures approximately 700'
across, thus meeting the '/< width rule. Work on this project would not cause any adverse impacts to coastal wetlands
but may cause minor turbidity within the river during construction. The applicant states that care will be made to
prevent any debris during construction and any sawdust from demolition and new construction from falling in to
the river. No dredging is being requested in this application.
