Subject: SR 1545 Coy Smith Road Hurricane Florence Pipe Replacement, Duplin County NC
WBS#: DF15403.2031222
(DWQ Permit Fee: $240)
Dear Mr. Shaver and Ms. Steenhuis:
The North Carolina Department of Transportation plans to replace an existing 54" in diameter by 70' in
length CMP which suffered damage as a result of Hurricane Florence at location Lat: 35.10286, Long:
-77.79154 on SR 1545 Coy Smith Road where it crosses Juniper Branch approximately 1 miles west of SR
1543 Guy Sanderson Road in Duplin County . The proposed replacement structure is (1) @ 84" in diameter
x 70' in length CMP w/Headwalls (See Attached Documents). NCDOT would like to request a waiver from
the depth specifications of the regional conditions 3.6.1 of the Nationwide Permit 3 and the corresponding
General Condition 11 of the Water Quality General Certification No. 4132. Due to the existing
geomorphologic fall of the stream channel, burying both of the inverts of the 84° CMP 1' would result in a
greater than 7 percent pipe slope, causing a high flow erodible condition. NCDOT plans to place the pipe on
a 3 percent slope leaving approximately 2' of fall on the outlet end to the natural stream grade.
Approximately 5 LF of additional rip rap used in conjunction with flowable fill is proposed to be placed in
the stream channel to protect from further scour and destabilization. (See Attached Permit Drawing).
By copy of this letter and enclosures, NCDOT is requesting issuance of Nationwide 3 approval from the US
Army Corps of Engineers and 401 Water Quality Certification (WQC) #4132 approval from the Division of
Water Resources (DWR). A method of debiting $240 to process the WQC request has been provided as
noted in the subject line of this application.
If you have any questions or need any additional information, please contact me at (910) 341-2033 or
at scfarrell@ncdot.gov.
Sincerely,
c�Q�CLrL �G� 22�

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 soi�s that cou�d have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Web Soil Survey URL:
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
of the version date(s) listed below.
Soil Survey Area: Duplin County, North Carolina
Survey Area Data: Version 14, Sep 10, 2018
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Mar 7, 2015—Oct 26,
2017
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.
