1.0 PROJECT DESCRIPTION
Construction of the new Bonner Bridge for NCDOT TIP B-2500 requires relocation of existing Cape
Hatteras Electric Cooperative (CHEC) transmission cable. A new transmission circuit is required to be
installed to provide uninterrupted electrical service to CHEC customers during and after the construction
of the NCDOT TIP B-2500 Bonner Bridge project. CHEC will install a new underground transmission
power line in Cape Hatteras National Seashore onto the new Bonner Bridge over Oregon Inlet in Dare
County. CHEC proposes to replace the existing circuit within its existing and NC DOT's right-of-way
easements granted by the National Park Service (NPS) and Fish and Wildlife Service (FWS). The existing
power line is encased in a cement "duct bank" (two feet by four feet (2'X4') concrete vault) on the
eastern side of NC Highway 12 which will be left in place after the new construction. The proposed
work detailed below comes after consideration of numerous line routes and construction methods. The
proposed route avoids as much environmental impact as practical. Through the course of design, the
alignment has been simplified by utilizing NC DOT right-of-way. Conflicts with road access to the nearby
fishing center and area wetlands are mitigated as much as practical by utilizing a horizontal directional
bore installation method for a portion of the transmission power circuit route.
The project consists of constructing the following:
1. A ten foot (10') wide temporary access road using removable matting from Oregon Inlet Road to the
existing CHEC substation north of Bonner Bridge (approximately 365 feet in length). This road will
mitigate impacts to the maintained wetlands around the substation to allow access for large utility
vehicles and construction equipment. Hand clearing (if needed) and between fifteen to thirty feet of
matting around the substation will be used to support this construction effort. After construction the
temporary access road and matted areas south and east of the substation will be converted to a
permanent gravel drive with turnaround for future maintenance access to the substation.
2. Installation of a new underground 115kV transmission power circuit consisting of:
a. A total of five (5) conduits in duct bank— four 6" conduits and one 2" inch conduit
b. Approximately 1,225 linear feet of four (4) foot wide and one (1) foot tall concrete duct bank
— utilizing a high early mix design for faster setting to close open trench sooner than typical
c. Approximately 420 linear feet of horizontal directional bore under Oregon Inlet Road and
maintained wetlands to inside the expanded substation fence
d. One below-grade utility vault — approximately ten (10) feet x twenty (20) feet x six (6) feet tall
e. No less than three (3) feet below grade to top of duct bank/vault
f. Duct bank to be open-cut trenched the total length of circuit from the new proposed bridge
end bent #2 to Oregon Inlet Road
Once the new transmission power circuit is installed and commissioned, power shall be transferred off
the existing circuit to the new. The existing CHEC duct bank is planned to be abandoned in place, with
the understanding that the National Park Service may require its removal at a future date. Any required
wetland mitigation resulting from transmission circuit relocation will be covered by the NCDOT B-2500
wetland restoration site.

Proposed land disturbance will be limited to the existing right of way areas adjacent to NC 12, the
existing substation, and near an existing overhead line on Pea Island where the cable will be connected
to a new overhead riser structure. Soil disturbing activities will include: installing erosion and sediment
controls, obstruction hand clearing, directional boring, open trenching, pole installation, a gravel access
road, and any necessary seeding and stabilization. Timber matting and hand-clearing will be used to
ensure wetland protection. Silt fencing and coir wattle will be used to prevent sediment from flowing to
nearby drainage ditches, riparian buffers, wetlands, and waterways. The total project limits north and
south of the bridge include 2.21 acres, of which 1.56 acres includes land disturbance. Impacts to
wetlands were minimized and include temporary hand clearing for pole construction and removal
access, as well as fill for a gravel drive. The built-upon area is only 7.6% of the total project area. Please
reference Appendix H for the Erosion and Sedimentation Control Plan drawings for more location and
design details.

2.0 EXISTING SITE CONDITIONS
This project site is located within the Tidewater Region of the Coastal Plain Physiographic Province in
Dare County. Terrestrial upland communities in the project corridor are represented by three major
community types: Man- Dominated (maintained/disturbed), Maritime Shrub Thicket, and Maritime
Shrub Grassland. The delineated wetland community types located within the corridor include: Man-
Dominated, Maritime Grassland, Maritime Shrub Thicket, and Maritime Shrub/Grassland. Neither
streams nor open water are affected by construction within the corridor. Land use is classified as
Parks/Bare Land - Outdoor Cultural, Public Assembly, and Recreation. Current site conditions are
disturbed for ongoing NCDOT construction. Shoreline erosion and nourishment are ongoing on Pea
Island. Cape Hatteras National Seashore wetlands adjacent to NC 12 and near the substation are
maintained by mowing.
The Corps issued the original DA permit SAW-2012-00715 to NC DOT on May 4, 2012 and SAW-1993-
03077 issued to NC DOT on August 20, 2013, with modifications approved October 21, 2015 for impacts
associated with TIP B-2500, replacement of the Bonner Bridge over Oregon Inlet. Impacts assessed for
the project in the 2008 Final Environmental Impact Statement and 2010 Environmental Assessment
included areas of study where relocation of utilities will be required by this project. Wetlands identified
in the 2012 delineation by CZR are shown on the Erosion and Sedimentation Control Plan drawings in
Appendix H. Please reference Appendix C for details on existing permits and wetland delineations.
The USGS Hydrologic Atlas indicates that the parcel is located fully within the Albemarle sub-basin of the
Pasquotank River basin of hydrologic unit code 03010205. The landscape slopes from an elevation of 13
feet to sea level and has an elevation of 3 feet AMSL at the substation up to 6 feet AMSL through the
transmission corridor. The project site is mostly flat draining into Oregon Inlet (30-22-1), Motts Creek
(30-21-13), and Roanoke Sound (30-21), which are in respective Classes SA/HQW, SC, and SA/HQW.
Coastal Area Management Act impacts were assessed on site to be avoided and no buffer rules are
applicable. Federal Emergency Management Agency (FEMA) DFIRM Flood Data lists the site in Panels #
373007 (2600J, 2500J, 3400J, and 3500J). Please reference the FEMA maps in Appendix D.

4.0 DESIGN APPROACH
In order to prevent sediment from leaving the project site, several erosion and sediment control devices
are to be installed. Construction entrances will be properly installed and any sediment tracked onto the
roadway will be cleaned up immediately. The disturbed site will have silt fencing installed around its
perimeter. In areas upslope of sensitive water bodies, it is recommended that standard silt fence
outlets be installed.
Care has been taken in design to avoid direct impact to wetlands; however the project site is in close
proximity to some wetlands. Impacts to park land were minimized in design by relocating the duct bank
into the NC DOT right of way, boring under Oregon Inlet Road, and boring under wetlands in front of the
substation adjacent to NC 12. CHEC has been working in coordination with NCDOT, Cape Hatteras
National Seashore, Pea Island National Wildlife Refuge, and associated permitting authorities to have
construction on the electric transmission cable ready to be attached to the new bridge structures in
accordance with the NCDOT project timeline. Construction on TIP B-2500 will continue for the next
several years; therefore, limited access for shared equipment laydown areas and construction access
require sequencing of permit approvals and bid schedules. Booth & Associates, LLC began interagency
coordination meetings between the NPS, FWS, NCDOT, CHEC, for the collaborative design of the Cape
Hatteras Electric Cooperative utility relocation in August 2016. A timeline was established for
coordination of using NCDOT right-of-way and having the cables installed and ready to pull onto the new
Bonner Bridge by December 2019. All disturbed areas will be stabilized by seeding and mulching. After
construction has ceased and the site is stabilized with permanent vegetation, the temporary erosion
control measures will be removed and stabilized with vegetative covering. The Owner, along with
NCDEQ shall determine when permanent vegetation is well established. For further detail, please see
Section 5.0 Construction Sequence and Section 6.0 General Construction Notes & Maintenance.
5.0 CONSTRUCTION SEQUENCE
5.0 Obtain all applicable permits. Contact NCDEQ Washington Regional Land Quality at 252-946-

disturbed areas will be limed, fertilized, or reseeded as necessary according to the rates
provided.
5.9 All erosion and sediment control measures will be inspected weekly and after each significant
rainfall event. Needed repairs will be made immediately and indicated on the stormwater
inspection forms kept in inspection box on site. The following items will be checked in
particular:
5.9.1 The silt fencing will be checked regularly for failures and repaired immediately. If
sediment accumulates to one-half (1/2) of the fence height, the sediment shall be
removed.
5.9.2 All seeded areas will be checked regularly to see that a good stand is maintained.
Areas will be fertilized and reseeded as needed.
5.9.3 Roadside culverts will be checked to ensure that sediment has not accumulated in
accumulated in the ditch. If so, remove the sediment and stabilize the ditch
immediately.
5.9.4 If sediment is found on road at any time during construction, it will be removed
immediately.
5.10 The following must be kept on site until the ESCP Plan has been closed out by Land Quality: 30
days of self-inspection records, rain gauge, approval certificate/letter, approved plan and
NPDES permit. These items should be located near the main construction entrance. Failure to
maintain these items on site violates the NPDES permit.
5.11 After the site is stabilized, coordinate with NCDOT to remove/reposition all temporary
sediment control measures and determine areas to apply permanent vegetation. After the silt
fences have been cleared of accumulated sediment, stabilize immediately with permanent
vegetation. All accumulated sediment shall be removed off-site to a NCDEQ permitted
location. The silt fencing is to remain until all construction is complete and permanent
vegetation is established. Silt fencing to be removed by owner.
5.12 Estimated time before phase 1 final stabilization is six (6) months. Estimated time before
phase 2 final stabilization is twelve (12) months. Estimated time before phase 3 final
stabilization is twenty-four (24) months.

6.6.10 Refer to the Park's annual Hurricane Plan for an outline of steps to be taken
under certain storm events and evacuations. The terms and conditions of this
plan and all directives issued by the Incident Command must be followed.
6.6.11 From May 1 through November 15, all lighting associated with the Project shall
be limited to the immediate area of active construction only and shall be the
minimal lighting necessary to comply with safety requirements. Only lights
approved in the Biological Opinion and subsequent Section 7 consultations are
required to minimize illumination of the nesting beach and nearshore waters.
Shielded low pressure sodium vapor lights are highly recommended for lights on
offshore equipment.
6.6.12 Discovery of Previously Unknown Remains and Artifacts requires halting
construction and must immediately be reported to the park's Cultural Resource
Specialist 252-475-9021 and District Engineer 252-475-8308. The district
engineer will initiate the Federal, Tribal, and state coordination required to
determine if the items or remains warrant a recovery effort or if the site is
eligible for listing in the National Register of Historic Places.

MAP INFORMATION
The soil surveys that comprise your AOI were mapped at
1:24,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as

The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
