Subject: Brunswick County US-17 Bus. Hurricane Florence Pipe Replacement
WBS#: 15403.1010020
(DWQ Permit Fee: $240)

Dear Mr. Shaver and Ms. Steenhuis:

The North Carolina Department of Transportation plans to replace an existing 3’ x 3’ x 60’ in length concrete
box culvert with two (2) 60” in diameter by 60’ in length CMPs at location Lat: 34.056300, Long: -78.160496
on US 17- Bus. where it crosses a UT to Middle Swamp (C; Sw) across from the Brunswick County
Government Complex, 0.05 miles SW of SR 1401 Galloway Road. 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
geomorphologic fall of the stream channel, burying both of the inverts of the new (2) 60” CMPs 1’ below the
natural streambed elevation would result in a greater than 8% slope causing a high flow erodible condition.
NCDOT plans to bury the inlet 1’ and install the pipe on a 3 % slope, which would set the outlet
approximately 1.37’ perched above the natural streambed elevation. Approximately 10 LF of riprap grouted
with flowable fill is proposed to be placed in the stream channel as a flume to protect from further scour and
destabilization. (See Attached Permit Drawings).

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 [phone] or at
[e-mail].

Sincerely,

Sean Farrell

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
of the version date(s) listed below.
Soil Survey Area: Brunswick County, North Carolina
Survey Area Data: Version 22, 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: Dec 31, 2009—Sep
30, 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.
