The meeting began at 1:30 p.m. with introductions and NCDOT Hydraulics giving a brief
description of the project. It was noted that curb and gutter was eliminated as much as
possible through out the project length. The following items were discussed:
Sheet 4:
NCDOT needs to verify if there is a wetland located right of station 25+50 -L-. A new
building has been constructed in this area, possibly impacting all or part of the wetland.
NCDOT noted that their design strategy is to provide as many storm water outfalls as
possible in an effort to minimize concentrating the storm water runoff.

Sheet 5:
NCDOT is proposing to replace the existing 2 @ 8 foot 2 inch by 5 foot 9 inch
corrugated steel pipe arches on Woodward Branch with an estimated 2 @ 12 foot by 6
foot reinforced concrete box culvert buried a foot.
NCDOT will investigate providing wetland mitigation by regrading the area upstream of
the new culvert on Woodward Branch down to the natural ground elevation from left of
station 33+00 -L- to 35+00-L-.
NCDOT will also investigate providing wetland mitigation on the property located
downstream of the new culvert on Woodward Branch from right of station 34+00 -L- to
35+00 -L-.
NCDOT will investigate piping the catch basin at station 16+00 -Y- (US 17 BUS.) to
station 17+00 -Y- to avoid outleting it directly into the wetland.
NCDOT will investigate if any of the drainage on the south east side of US 17 Bus. From
station 16+00 -Y- to 19+00 -Y- can be drained to the other side of the road instead of
directly into Woodward Branch. It was noted that due to elevation constraints that this
probably was not possible.
Sheet 6:
NCDOT discussed the impact of the project on the wet detention pond located around
station 53+00 -L-. NCDOT had originally planned on relocating the pond to the south
side of the road. Hydraulics noted that the NCDOT Right of Way Department had
discussed this option with the Attorney General's Office and determined that we could
not purchase or condemn land from a third party for a replacement pond.
Hydraulics then noted another option was to rebuild the pond on the original property
owner's land on the north side of the road. Two locations on the north side were
investigated. One location was to the west of the existing pond left of station 50+00 -L-
on commercial property of the Shallotte Crossings development. It was determined that
right of way cost associated with this location would be enormous. The other location
would be just north and east of the existing pond on a designated retention pond easment
between the proposed roadway and the Shallotte Crossings development. In order to
rebuild the pond in this location approximately 850 feet of stream (Unnamed Tributary to
Sharon Branch) would have to be piped around the new pond.
The third option discussed was to revise the Roadway alignment to the south of the pond
in order to avoid the pond. This option required a reduction in the design speed of the
proposed road from 40 mph to 35 mph. The Roadway Design Unit noted that although
this option was not preferred that it would be an acceptable design for the project. It was
estimated that this option would impact approximately 200 feet of stream (Unnamed

Tributary to Sharon Branch). It was not known if additional wetland impacts would be
incurred due to the new alignment. A site visit will be required to determine if there are
additional wetlands located where the new alignment is proposed.
After discussing the options, the team members agreed that revising the roadway
alignment to the south of the pond in order to avoid relocating the pond would be the best
option pending the investigation of wetlands in this area.
Sheet 7:
Hydraulics will use a grass swale along the right side of the road from approximately
station 57+00 -L- to station 61+00 -L-.
Hydraulics may have to pipe the storm drainage at station 64+00 -L- and 62+00 -L- back
to station 60+00 -L- in order to avoid ditching through the wetlands right of station
62+00 -L-.
Other comments:
NCDCM had previously noted that there are no Areas of Environmental Concern
(AEC's) located in the project area. They noted that the proposed project will not require
a CAMA Permit but will be processed by the Division of Coastal Management through
concurrence with a Consistency Determination to be submitted by the DOT as part of
any request for a federal permit. NCDCM will double check to make sure that this is
still the case.
Post meeting Activities
DCM has confirmed that no AECs will be impacted in the project area. The project will
not require a CAMA permit but will be processed by DCM through concurrence with a
consistency determination.

STORMWATER MANAGEMENT PLAN
U-3462, WBS No.: 93453.1.1
Brunswick County
Hydraulics Project Manager: Andrew Nottingham, PE
ROADWAY DESCRIPTION

Date:8-01-07
The project involves the widening and extension of SR 1357 (Smith Ave) in Shallotte.
The project begins on Smith Ave. just west of the US 17Bus/NC 130 intersection and
extends Smith Ave. from this intersection in a eastward direction for approximately 0.87
miles on new location and ends at NC 130 approximately 0.4 miles east of US 17Bus.
The overall length of the project is 1.23 miles. The proposed typical section varies along
the project and generally consists of a 4-lane roadway section. Curb and gutter is used in
the vicinity of the intersection of existing US 17Bus/NC 130 and shoulder section is used
on the rest of the project.
ENVIRONMENTAL DESCRIPTION
The project is located in the Lumber River Basin in the Coastal Physiographic Province.
There is one major stream crossing (Charles Branch) on this project, located on SR 1357
(Smith Ave.), approximately two hundred feet west of US 17Bus/NC 130. In addition to
this crossing, there are two other areas of noted concern. A tributary to Charles Branch
paralleling SR 1357 (Smith Ave.) on the west side and a tributary to Sharron Branch
behind the Home Depot approximately 0.30 miles west of the project's eastern terminus.
Charles Branch is classified as Class C, Sw, and HQW waters. Sharron Branch is
classified as SC and HQW waters. The existing stream crossing at Charles Branch will
be replaced with a new RCBC on new location to the west of existing. The existing 6' x
5' culvert on US 17Bus will also be extended upstream.
A 72" rcp, buried 1.0 foot, on new location will be used to convey the tributary of
Sharron Branch, located southeast of the detention pond for Home Depot.
Approximately 380 feet of existing stream will be impacted due to the project. Seven
wetland sites will be impacted. Approximately 0.15 acres of wetlands will be impacted
due to this project.
BEST MANAGEMENT PRACTICES AND MAJOR STRUCTURES
Best Management Practices (BMPs) and measures used on the project are an attempt to
reduce the stormwater impacts to the receiving streams due to erosion and runoff.
Grassed swales were used to treat stormwater runoff prior to entering the streams. The
inverts of all new culverts on jurisdictional streams or wetlands will be buried 20% of the
pipe diameter up to 1 foot deep. There is one major stream crossings consisting of a new
reinforced concrete box culvert and one major stream crossing consisting of a reinforced
concrete box culvert extension.
