Subject: Letter of Authorization for the Use of Radio Island
Property in Support of the Radio Island Shoreline and
Infrastructure Protection Project
Dear Mr. Foxworth,
On. behalf of the North Carolina State Ports Authority (NCSPA), please use
this letter to serve as official authorization for Carteret County to utilize
property on the southern. portion of Radio Island to be utilized as a dredged
material containment area (DMCA). It is the understanding of the NCSPA
that a DMCA will only be necessary if hydraulic dredging is the selected
construction methodology for the project. A DMCA will be required to be
able to control hydraulically dredged material on the recipient beach. The
DMCA to be constructed will be comprised of two areas- the primary
material containment area and, the water clarification area.
It is the understanding of the NCSPA that Carteret County and its agent,
Moffatt & Nichol, will coordinate with the NCSPA prior to construction and
once . a construction methodology is determined. The NCSPA will coordinate
with Carteret County and its selected contractor for full access to the site
during the timeframe of construction, anticipated to be December 1, 2021 -
May 1, 2022. This timeframe includes the time for demobilization of
equipment and restoration of the area to original condition. to match grades
and vegetation.
Sincerely, .1

Dear Ms. York,
SUBJECT: MARINE ROAD ACCESS AUTHORIZATION
Joint Expeditionary Base Little Creek -Fort Story (JEBLCFS) is pleased that Carteret County is
moving forward with its permit application for Radio Island's shoreline and infrastructure protection
project. We are in receipt of your request for the County's selected contractor to use Marine Road
for access, movement, and placement of heavy equipment to construct related improvements.
Please be advised that a section of Marine Road, approximately 630 feet in length, has been
undermined by erosion and programmed for repair. As a result, concrete jersey barriers have been
installed to divert traffic from these undermined pavement sections and onto a bypass road.
Therefore, the County's selected contractor will be required to work around the damaged sections, as
well as provide cribbing and pallets to protect existing pavement froin further damage.
In closing, all construction activity will need to be coordinated with the installation's Port
Operations Department to ensure continuity of access to the road and avoid disruptions to its training
requirements. Authorization of the County's selected contractor to use Marine Road as requested is
therefore contingent upon its recognition of and compliance with the herein stated conditions.
Please contact niy Community Planning and Liaison Officer, Mr. Earnest McDonald, AICP, at
caniest,iiiedonald('ii,',tiavy.miI with questions or other concerns relating to this authorization.
Sincerely,

8. PROJECT SUMMARY:
The applicant is proposing a major modification to major permit 35-20 issued on
3/27/2020. The applicant wants to reuse the previously permitted dredge material that
would be removed from the east end of Taylors Creek for beach nourishment along the
eastern shoreline of Radio Island and would also like to locate the spoil disposal site on the
property along the southwest portion of Marine Drive for the DMCA. All original depths,
channel location and dredge calculations would remain as previously permitted.
9. Narrative Description
The Carteret County Radio Island Shoreline and Infrastructure Protection Project is
located along the eastern shoreline of Radio Island and on the property located at the

Field Investigation Report:
Carteret County Radio Island Shoreline and Infrastructure Porject
Page 02
southwest side of Marine Drive in Beaufort, Carteret County. The eastern shoreline of
Radio Island is leased by Carteret County from The NC State Ports Authority and is 2,775'
in length. This area of Radio Island serves the public as a recreational beach. The NC State
Ports Authority has also given permission to use their south west property for the DMCA.
The us government owns a 3.9-acre portion at the south end of Marine Drive that supports
the US Navy/Marine Corps Landing Craft Utility operations. There are private properties
located along the north portion of Radio Island.
The Town of Morehead City's Land Use Plan classifies this area as Port Mixed -use and
Conservation. This section of Taylors Creek and the west side of Radio Island (Newport
river) is not designated as Primary Nursery Area, is closed to the taking of shellfish and
carries a water classification of HQW. Riparian corridors were not determined.
10. Project Description:
The current proposal is for the reuse of beach compatible dredge material permitted through
CAMA major permit 35-20 through beach nourishment as well as construction of a new
location for spoil disposal with the creation of a DMCA on the south western property along
Marine Drive that is owned by the NC State Ports Authority. Marine Drive is heavily utilized
by the public and the US military for training therefore according to the applicant this project
would promote compatible land use by preserving the established public access beach area
on the island, restore natural habitat and serve as a barrier to protect critical infrastructure
that provides accessibility to the US Navy's LCU ramp and utility service.
Carteret County would like to reuse beach compatible dredge material from the East
Taylors Creek dredge project to nourish the 2,820 southeast section of Radio Island. The
design template for restoring and stabilizing the shoreline consists of placing 10 cubic
yards per linear foot of material along the shoreline. The placement geometry consists of a
dune system (8' above existing grade) of varying top width (20 to 35') that transitions to a
beach berm that varies between 20' to 60' . Per the applicant the beach berm transitions to
existing grade between +3' NAVD88 and -5' NAVD88. The design template would vary
as placement progresses continuously along the beach, with changes to the top width of the
dunes and beach berm to match existing grades and nearshore slopes. The county believes
this project would help improve and ensure the protection to the county infrastructure that
supports public access to the beach along the northern extent of the project.
There would be two primary methods of dredging and transporting the material for
placement on the beach. Hydraulic dredging with mechanical placement or mechanical
dredging with mechanical placement. The county is proposing both methods in order to
present both of the options to the selected dredge contractor, who would then select the
most advantageous option based upon equipment needs, availability, schedule and cost.
The mechanical dredging would consist of a clamshell or excavator type that would
remove the spoil material from East Taylors Creek for placement at Radio Island. The
spoil would be placed on a barge for transport and dewatered during transport. Once the
spoils are at the site they would be placed along the beach strand via an excavator or
clamshell within the beach fill template and final shaping would occur using an excavator

or bulldozer on the beach.
There would be four main aspects to the hydraulic construction methodology; dredged
material containment area (DMCA), pipeline conveyance, hydraulic dredging and beach
fill placement.
a. DMCA
In order to stabilize the material on Radio Island and be able to control the
dredged material the applicant is proposing a DMCA. There would be two areas
for the DMCA; the primary containment area and the water clarification area.
The primary containment area would be constructed utilizing a series of dikes
that would be built to have a crest elevation of + 28' NAVD88. The material
used to construct the dikes would be excavated from the proposed DMCA site.
The hydraulically pumped spoil material would be placed into the primary
containment area, in slurry form, where it would remain while the material
settles. The effluent would run off through a fixed elevation water control
structure into the water clarification area. The material in the primary placement
area would be stockpiled to a maximum elevation of +34' NAVD88 however the
level of any ponded area would only be allowed to pond at a maximum elevation
of +26' NAVD88 in order to maintain 2' of freeboard within the primary
placement containment dikes. Pipe lines would be used that would adjust the
ponding elevation through the use of weir boards to maximize the ponding
elevation needed for clarification of the effluent. Due to the existing topography,
in order to maintain 2' of freeboard the maximum elevation of the water would
be allowed to be ponded at +10' NAVD88, which per the applicant should allow
for over 24 hours of retention time prior to discharge of the effluent. After
removal the dredge material from the primary placement area dikes would be
shaped as close as possible to pre-existing conditions and the clarification area
would be drained of any freestanding water.
b. Pipeline Conveyance
The material dredged from East Taylors Creek would be hydraulically pumped
in a slurry from through a pipeline that would be placed between Carrot Island
and the Taylors Creek navigation channel. The contractor would determine the
best location for pipeline crossing the Bulkhead channel based on pipeline size
and surrounding bathymetry to help ensure the pipeline does not impede on
advertised navigation depths. The pipeline would come ashore within the project
area and then would be laid beneath Marine Drive by open cut and cover
placement to reach the DMCA. Once dredging is concluded the pipeline would
be removed.
c. Hydraulic Dredging
A hydraulic dredge would excavate the material from East Taylors Creek using a
rotating cutter head that would loosen the material and then would be suctioned
into the pipeline in slurry from. The material would be transported to the DMCA

Carteret County Radio Island Shoreline and Infrastructure Project

site through the pipeline.
d. Beach fill Placement
After the material is placed within the DMCA has sufficiently dewatered it
would be excavated from within the dike area with excavators or front end
loaders and loaded into off road trucks which would transport the material to the
beach nourishment site and down to the beach area. The material would be
dumped within the beach profile with the final profile and grading occurring
with bulldozers and excavators on the beach.
11. Anticipated Impacts:
The beach nourishment would fill 352,800 sf of estuarine shoreline with the DMCA filling
550,000 sf of high ground for spoil containment. Depending on the dredging method, the
spoils would be contained within a transfer barge or at an upland area., Future beach
nourishment would be anticipated.
