Dear Sir:
6si~o~ v.2
Subject: Nationwide 23 & 33 Permit Application and Neuse Riparian Buffer
Authorization Request for the Replacement of Bridge No. 60 (Alfred
Cunningham Bridge) over the Trent River on US 70 Business (East Front Street);
Craven County; TII' Project B-2532; Federal Aid Project No. BRSTP-070B(4);
State Project No.8.1172401; WBS 32649.1.1.
Please find enclosed the Preconstruction Notification (PCN), permit drawings, half-size plans,
and the Categorical Exclusion (CE) for the above-mentioned project. The North Carolina
Department of Transportation proposes to replace existing Bridge No. 60 over the Trent River on
US 70 Business in Craven County. The project involves replacement of the existing swingspan
bridge, related approaches, and traffic control devices with a bascule bridge, new approach
structures, and new traffic control devices. The new bridge will feature two 11-foot lanes with a
4-foot shoulder along the northbound lane and atwo-foot gutter along the southbound lane. A
sidewalk (5.5 feet in width on the bridge and 5 feet in width on the roadway approaches) will be
provided adjacent to the southbound lane for the entire project length. Total project length is
2,480 feet with the bridge comprising 1,762 feet. The project schedule calls for a January 16,
2007 let with a review date of December 12, 2006. Proposed permanent impacts include 6,049
sq. feet of surface water impacts for drilled piers and Bascule footings. Proposed temporary
impacts to surface water will be 630 sq. feet for cofferdams to construct the piers.
Impacts to Water of the United States
General Description: The Trent River is located in the 03020204 CU of the Neuse River Basin.
The Division of Water Quality (DWQ) has assigned the Trent River a Stream Index Number of
03-04-10. DWQ has assigned a best usage classification of SB Sw NSW.

The Trent River is not designated as a North Carolina Natural or Scenic River, or as a national
Wild and Scenic River, nor is it listed as a 303(d) stream. No designated Outstanding Resource
Waters (ORW), High Quality Waters (HQW), Water Supply I (WS-I), or Water Supply II (WS-
II) waters occur within 3.0 miles of the project study area.
Permanent Impacts: As stated above, permanent impacts consist of drilled shaft piers and
Bascule bridge footings. The total amount of surface water impacts is 0.139 acre.
Temporarypacts: Temporary impacts to surface waters for this project is 0.014 acre for coffer
dams needed to construct the footings for the bridge. The size and shape of the workbridge is
generally left to the contractor.
Utilitv Impacts: There will be no impacts to jurisdictional waters due to utilities. The only
utilities associated with this project will serve the Bascule bridge and the bridge tender's house
only.
Neuse Buffer Rules: This project lies within the Neuse River Basin; therefore, the regulations
pertaining to the Neuse River Buffer Rules will apply. Because the bridge is located within an
urban area, most of the buffer zones have pre-existing bulk-heads and/or rip-rap. To comply with
the Neuse River Riparian Buffer requirements, all improvements associated with B-2532 will
remain inside the limits of the existing transportation facility and, therefore, this project is
considered exempt from the buffer rules.
Bridge Demolition
The superstructure for Bridge No. 60 will allow removal without dropping components into the
water. Likewise, it should be possible to remove the timber piles without dropping them into the
water. The concrete piers may result inasmuch as 10 cubic yards of fill depending on the
method of removal to be determined after a contractor is selected. Best Management Practices
for Bridge Demolition and Removal will be implemented. Any component of the bridge dropped
into the water shall be immediately removed.
Avoidance and Minimization
To avoid impacts, NCDOT is replacing Bridge No. 60 in place and utilizing anoff--site detour.
NCDOT is also minimizing impacts to surface waters by utilizing longer spans with less bents
than the existing bridge.
NCDOT will observe an in-stream construction moratorium from February 15 to June 30 and
utilize Stream Crossing Guidelines for Anadromous Fish Passage.
To avoid temporary impacts due to a workbridge, NCDOT will utilize a barge for demolition and
bridge construction where feasible.
2

To minimize impacts to submerged aquatic vegetation (SAVs), efforts will be made to avoid
barge contact with the substrate and minimize shading during the growing season (May -
September). Logistics associated with minimizing shading include maintaining an elevation of at
least three feet above normal high tide (+0.7 feet) for work bridges and avoiding or minimizing
long term mooring of construction barges during the growing season. Reasonable efforts will also
be made to avoid bottom disturbances in areas of SAV beds during the growing season.
Mitigation
Mitigation is not proposed for this project. Permanent impacts are due to piers and the temporary
impacts are due to the workbridge and coffer dams. There are no impacts to the Neuse River
Riparian Buffers since the project is staying within the existing transportation facility.
Federally Protected Species
As of March 8, 2006, the US Fish and Wildlife Service (LJSFWS) lists six federally protected
species for Craven County. The following table lists these species.

Regulatory Approvals
Section 404 Permit: This project is being processed by the Federal Highway Administration as a
"Categorical Exclusion" in accordance with 23 CFR 771.115(b). Therefore, we do not anticipate
requesting an individual permit but propose to proceed under a Nationwide 23 and 33 as
authorized by a Nationwide Permit 23 (67 FR 2020; January 15, 2002).
Section 401 Permit: We anticipate 401 General Certification numbers 3403 and 3366 will apply
to this project. In accordance with 15A NCAC 2H, Section .0500(a) we are providing two copies
of this application to the North Carolina Department of Environmental and Natural Resources,
Division of Water Quality, for their review.
Neuse River Riparian Buffer Authorization: This project lies within the Neuse River Basin;
therefore, the regulations pertaining to the Neuse River Buffer Rules will apply. However, all
improvements associated with B-2532 will remain inside the limits of the existing transportation
facility and, therefore, this project is considered exempt from the buffer rules.

Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that maybe appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.

• Bridge No. 60 on US 70 Bus. over the Trent River
Hydraulics Project Manager: Andrew Nottingham, PE
STORMWATER MANAGEMENT PLAN
PROJECT DESCRIPTION
The NC Department of Transportation proposes to replace bridge no. 60 with a
bridge. US 70 Business in the vicinity of the project is an urban local route that connects
historic New Bern at the northern terminus of the project to James City at the southern
terminus of the project. The existing roadway cross section varies from two lanes with an
overall width of 36' across the bridge to 72' at the southern terminus where it intersects
with US 70 Bypass.
The existing structure consists of multiple 35' approach spans north and south of a
220' main swing span. The overall bridge length is 1760'. The proposed structure will
have multiple spans north and south of a 166' bascule span. The overall bridge length
will be 1762' .
Bridge deck drainage is accomplished with deck drains on both the existing bridge
and the proposed bridge. Proposed deck drains will be eliminated from the first 3 spans
of the bridge (282'), except directly above the rip rap slope protection at the southern
abutment. Similarly, deck drains will be eliminated from the last four spans of the bridge
(285') except directly above the rip rap slope protection at the northern abutment.
The existing concrete and timber bulkheads will be retained on either end of the
bridge. The relatively flat area between the bulkhead and the bridge abutment will be
amended with rip rap to provide scour protection. This area will also act as an infiltration
area for the deck drains mentioned above.
The existing bridge has two 3' sidewalks on either side of the bridge. The new
bridge will have just one 5'6" sidewalk along the western side of the bridge. 300' of
existing sidewalk will be removed along the roadway at the northeast end of the bridge.
A 570' sidewalk with curb and gutter will be added along the western side of the roadway
from a drive at the southern project terminus to the beginning of the bridge. The
difference in the sidewalk improvements will add approximately 1350 square feet
(0.031acre) of impervious area within the project limits.
Traffic will be detoured off-site during the bridge construction.
ENVIRONMENTAL DESCRIPTION
The surrounding land use consists of residential, commercial, and industrial uses. The
project area is located in the Neuse River Basin at the confluence of the Trent River with
the Neuse River. The surrounding terrain is generally flat to very flat. The natural
ground elevation at the site is approximately 4' NGVD. The water depth at the site is
approximately 14' in the channel. The best usage classification is NSW, SB, Sw. No
watershed critical areas, HQW, or ORW waters are located within one mile of the project
site.

• The bridge replacement will be accomplished with a road closure that will minimize
construction time and on-site impacts.
• The roadway typical section is a fill section with slopes no steeper than 3:1.
• The added curb and sidewalk section will use a level spreader device for additional
treatment.
• Proposed deck drains will be eliminated from the first 3 spans of the bridge (282'),
except directly above the rip rap slope protection at the southern abutment. Similarly,
deck drains will be eliminated from the last four spans of the bridge (285') except
directly above the rip rap slope protection at the northern abutment.
• Discharge from the deck drains will be allowed to infiltrate the natural ground behind
the existing bulkheads.
• Placement of rip rap beneath both bridge ends between the bulkhead and the bridge
abutment will control erosion from deck drains and storm event scour.
• To avoid impacts to SAV's, bridge construction in shallow water will be limited to a
work bridge.

NCDOT will also need to perform a pile test drive as part of the site characterization. The pile drive test
will be performed in the river from a barge using equipment provided by and operated by the NCDOT
Bridge Maintenance Unit or one of its consultants. The planned pile type to be driven is a 12 x 53 Steel
H-pile. There are two possible locations for driving the test pile. The location closest to the Convention
Center is preferred but it will not be known until the equipment arrives on site if it will be feasible to
work at that location. The location on the East side of the existing bridge should not present any
problems for equipment access. The equipment used to drive the pile will be similar to the following: a
40 foot by 80 foot work barge, a 50 ton track mounted crane, and aDel-Mag model D12-32 diesel drive
hammer. The test pile will be driven with no jetting. The pile will be pulled back out if possible. If it
cannot be pulled out then it will be cut off below the river bottom, which would require some disturbance
of the riverbed. The maximum area that may be disturbed from the test pile drive and removal is
estimated to be 706 Ft2.
In order to ensure compliance with best management practices, all attached General and Regional
Conditions associated with Nationwide Permit 6 and WQC #3494 will be followed. The NCDOT
anticipates that these activities are authorized under Nationwide Permit 6, therefore we are not requesting
written verification. NCDOT will follow the conditions set by a Nationwide Permit 6 and by NCDWQ
Water Quality Certification # 3494. In accordance with 15A NCAC 2H.0501 (a), we are providing two
copies of this letter to the NCDWQ for their records.
If you have any questions or would like additional information, please call Mr. Chris Underwood at (919)
715-1451. Thank you in advance for your help in this matter.
Sincerely,
