Memorandum To: John Dorney
From: Todd St. John
Subject: Lake Concord Road Bridge
Cabarrus County
DWQ# 010297
I have reviewed the submittal provided in order to meet condition no. 1 of the subject WQC
issued April 2, 2001. The condition requires that the channel shift must reflect the existing stream
profile and dimensions. It also requires a plunge pool at the end of the new stormwater pipe.
Two plunge pools are shown in the plans. Additionally, the plans for the channel realignment
show the channel will be straightened as it passes under the bridge. The channel will then be
hardened with rip rap. A flow analysis using HEC RAS appeared to show that hydraulics under the
bridge will change but not in a manner that is very different from what the model predicted for existing
conditions. The model also showed that conditions immediately upstream and down stream to be
similar between existing and proposed conditions. The channel under the bridge will also be slightly
widened and deepened. Because the area of deepening and widening is so short the overall effect
may be that of creating a pool which may balance the fact that the channel will be shortened by the
straightening. The results from the model seem to show this, assuming they ran it correctly with
adequate up and down stream stations (not provided). In any event, the new channel appears to
include and adequate flood way to relieve stresses on the channel under the bridge allowing larger
flows to access the flood plain and not be constricted to the channel. As such, I recommend that the
realignment plans be approved.

APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Paul Campbell
City of Concord
850 Hwy 601 South

Concord, NC 28026
Dear Mr. Campbell:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill material in 140 linear feet of streams for the purpose of improving Lake
Concord Road bridge over Three Mill Branch as described in your application dated
December 22, 2000 (received February 27, 2001). After reviewing your application, we have
decided that this fill is covered by General Water Quality Certification Number 3289. This
certification allows you to use Nationwide Permit Number 14 when the Corps of Engineers
issues it. In addition, you should get any other federal, state or local permits before you go
ahead with your project including (but not limited to) Sediment and Erosion Control, Coastal
Stormwater, Non-Discharge and Water Supply Water shed regulations. This approval will
expire when the accompanying 404 or CAMA permit expires unless otherwise
specified in the General Certification.
This approval is only valid for the purpose and design that you described in your
application except as modified below. If you change your project, you must notify us and you
may be required to send us a new application. If the property is sold, the new owner must be
given a copy of this Certification and approval letter and is thereby responsible for complying
with all conditions. If total wetland fills for this project (now or in the future) exceed one acre,
compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h) (6) and
(7). For this approval to be valid, you must follow the conditions listed in the attached
certification and any additional conditions listed below.
The 140 feet of channel shift must reflect the existing stream profile and dimensions and
have a plunge pool at the outlet of the new stormwater pipe. A detailed plan must be
submitted to DWQ (Mr. Todd St. John) for written approval before impacts occur.
2. Upon completion of the project, the applicant shall complete and return the enclosed
"Certification of Completion Form" to notify DWQ that all the work included in the 401
Certification has been completed. The responsible party shall complete the attached form
and return it to the 401/Wetlands Unit of the Division of Water Quality.

Comments:
The applicant is proposing to replace an existing bridge over Threemile Branch with a larger bridges.
accomadate a road widening project for Lake Concord Road in Concord. The existing bridge was
constructed parallel to the road causing the creek to turn slightly out of what appears to be its origjnal
pattern. The new bridge will be constructed so that the piers are parallel to the stream and the
stream will he realigned under the bridge with its original channel. Currently there is a large pool on
the upstream side of the bridge. a riffle complex under the bridge and a pool at the downstream side
of the bridge. There is also a large stormwater outfall on the upstream side that will be relocated to
the downstream side during contstruction of the new bridge.

Dear Mr. Dorney:

Attached is a Pre-Construction Notification Application for a Nationwide Permit
#14 and Section 401 Water Quality Certification for the replacement of the Lake
Concord Road bridge in Concord, NC. The bridge is located in Cabarrus County
0.45 mile south of I-85 spanning Threemile Branch on Lake Concord Road
approximately 225 feet south of the intersection with Mall Road (see attached
location map). The existing bridge, shown on the attached USGS map (Concord
quadrangle), is 78 feet long and 42 feet wide. Threemile Branch is
approximately 15-25 feet wide and approximately 1 foot deep in the project area.
The City of Concord has determined that traffic levels along Lake Concord Road
require widening the road. The existing bridge is too narrow for the proposed
road, and permit authorization is being requested to replace the bridge. The need
for a wider road arose from current traffic levels and expected increases in future
traffic levels. Additionally, Lake Concord Road will provide direct access to a
regional medical center from I-85 after the widening project. Currently, the
emergency vehicles must take an alternate, less direct route to the medical center.
The exiting bridge will be removed and replaced in its existing location by a
92'x78' bridge (see attached site plan) in order to address these needs.
The existing bridge will remain in place while half of the replacement bridge is
built. The existing bridge will then be removed, and the remainder of the
replacement bridge will be constructed. A stormwater outlet into Threemile
Branch will be relocated. In order to protect the new bridge structure, riprap will
be required on the upstream and downstream banks by the bridge. The channel
will also be shifted slightly to prevent erosion around the footings as it flows
beneath the ride. The bridge is located within the 100-year floodplain, but
significant fill will not be placed in the floodplain, and the 100-year flood

elevation will not be increased. No wetlands occur in the project area, therefore,
the project will have no wetland impacts.
In order to preserve water quality and reduce the impact of this project, sediment
erosion and control measures will be in place before construction. Additionally,
rip-rap placement will be the minimum required to protect the structure. Total
stream impact from rip-rap and the channel realignment will be 140 feet. No
damming of water will take place during construction and channel shifting. The
new channel will have a more natural pattern and profile than the existing altered
channel. Flood control measures have been designed into the project to avoid
changes in the 100-year flood level.
A site vicinity map, USGS quadrangle, and site plans have been included for
your reference.
Thank you very much for your attention to this project.
Very truly yours,

12. DESCRIPTION OF PROPOSED WORK INCLUDING DISCUSSION OF TYPE OF MECHANICAL
EQUIPMENT TO BE USED? (ATTACH PLANS; 81/2 BY 11 DRAWINGS ONLY)
The existing bridge will be replaced by a wider bridge to accommodate the road widening project on
Lake Concord Road. Half of the new bridge will be build next to the existing bridge. The existing
bridge will then be removed and the remaining half of the new bridge will be built in its place. A
crane will most likely be used to place footings. The new bridge will measure 78' wide by 92' long.
The existing bridge measures 42' wide by 70' long. Relocation of the channel will be necessary to
protect the new structure. Relocation will take place at the upstream entrance of the bridge and will
consist of a shift of approximately 10 feet. The minimum riprap necessary to protect the structure
will be placed along the banks on the upstream and downstream sides of the bridge. Temporary
damming of the stream will not take place during this project. However, some constriction to the
flow will occur during channel relocation. Total impacts from the bridge and rip-rap will be 140 feet.
13. PURPOSE OF PROPOSED WORK: The City of Concord has determined that Lake Concord Road
must be widened to accommodate current and expected future traffic levels. The road will serve as a
direct route for emergency vehicles from I-85 to a local hospital. The existing bridge is too narrow to
service the road after the widening project. It will be replaced with a wider structure.
