Dear Mr. Biddlecome,
The North Carolina Department of Transportation is requesting a GP 31 permit for an Emergency
Bridge support project. The proposed work will occur on bridge # 11, which is located over Oregon Inlet
along NC 12 in Dare County. This project proposes to restore bottom elevations to minimum embedment
for the bridge pile supports between bents 156 - 166 on the south side of the Inlet. During recent depth
soundings and bridge survey reviews, it was discovered that bridge pilings at bent # 156 through bent # 166
are below the minimum pile embedment depth. This means that the bottom contour has eroded away to a
critical point around the pile structure. This lack of ground support around the piles is very concerning to
bridge structural engineers and warrants immediate action. In order to reduce the scour and restore bottom
contours to minimal embedment, NCDOT has designed a precast concrete current dissipater, which will
allow sediment to settle out around the pilings, restoring bottom contour elevations and preventing
additional scour. The concrete current dissipater unit is made up of a 6 arm structure, which individually
measures 4 feet by 4 feet. In order to reduce the erosive current around the piles these concrete units will be
interlocked in an'arrangement that creates a continuous row. The row will be 8 feet wide at the base and
layer to a height of approximately 6 feet, resulting in a pyramid shaped row. The individual concrete units
will be interlocked and bound together using a high strength polypropylene rope. The provided permit
drawings and photographs illustrate the arrangement. These interlocked units will be placed parallel to the
bridge on the east and west side, beginning at bent # 156 and continuing 676 feet to bent # 166. The
proposed alignment is off set approximately 5 feet from the outside pile. The clusters will be placed by a
barge/tug and diving operation. Once the clusters are placed on the bottom they are tied together to create
one continuous row of interlocked clusters. The total footprint on the bottom will be 10.800 square feel.
After the row placement and predicted sand collection, the minimum depth between bent 155 and 156 will
be approximately 15 feet from Mean Low Tide.
The barge and tug operation will utilize an old existing emergency ferry landing on the south side
of Oregon Inlet. This landing has been used in the past and provides efficient barge access. The existing
paved roadway that leads to the old ramp will need to be temporary extended approximately 60 feet to
accommodate barge access. This will be done by the placement of 4 feet by 4 feet sandbags, layered with a
rubber mat and wooden palate. This will result in a temporary impact of 0.011 acres of open water. Once
the project is complete, the roadway/ramp extension will be entirely removed. A permit detail and
photograph illustration depicts the proposed temporary roadway/ramp improvement.
113 Airport Drive, Suite 100, Edenton, NC 27932, Phone [phone], Fax [phone]
NCDOT is also requesting a modification to CAMA Major Permit # 128-04, which was originally
issued in 2004 for a very similar project on the Bonner Bridge at Bents 146 and 147.
NCDOT is coordinating with the USFWS on this project. This will be done through a Special Use
permit issued by the USFWS Marten office.
The PCN, vicinity map, photographs and permit drawings are included with this letter. If you need
any additional information or have any questions concerning this project please call me at 252-482-7977.

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The project site's only structure consist of the Bonner Bridge, which crosses Oregon Inlet. On the southside of the inlet
there is a rock terminal groin that extends from the soundside to the ocean. The bridge is bordered on the north by the
National Park Service Property (Bodie Island) and the south by the USFWS property (Pea Island). General land use is in
conservation and is used by recreational fisherman, beach tourism, bird watchers, and boating.
3b. List the total estimated acreage of all existing wetlands on the property:
2 acres
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
0
3d. Explain the purpose of the proposed project:
Emergency response to reestablish minimum embedment above critical scour points at pile supports, between bents 157
and 166 on the southend of Bonner Bridge. This will be done by inducing sand collection around bridge piles.
3e. Describe the overall project in detail, including the type of equipment to be used:
The project proposes to place two 676 foot long rows of concrete jacks paralell to the bridge beginning at Bent # 156 and
extending south to Bent # 166. The rows of concrete jacks will be placed on the east and west sides of the bridge,
opposite of each other. Each row will be approximately 8 feet in width at the base (3 jacks wide) and pyramid to 4 feet
wide at the top row (2 jacks wide). These jacks will be placed a distance of approximately 5 feet away from the outside
support piles as shown on the diagrams. The jacks will be interlocked and cabled together to insure anchoring and
stability. They will be placed by use of a crane and diving operation. The crane operation will be conducted from a floating
which will manuever as directed. The barge loading site will be on the southside of the inlet at the Old
barge and tug
,
which has been utilized in past Bonner Bridge repair work. This loading site will have to be temporarily
Ferry Ramp
,
improved to allow for a barge loading operation. The old roadbed will be extended approximately 33 feet as shown in the
attached detail. The extension will involve placing 4'X4' sand bags as a base, layered with a rubber mat and timber pallet
riding surface. The attached detail illustrates the improvement. Once the project is complete, this temporary road
extension will be completely removed. There will be no wetland impacts associated with the proposed work.
This project will require transport equipment/ trucks, tugs, barge, and crane.
