TROGDON, III GOVERNOR SECRETARY Brad Shaver, NCDOT Coordinator Joanne Steenhuis, NCDOT Coordinator Wilmington Regulatory Field Office NC Department of Environmental Quality US Army Corps of Engineers Division of Water Resources 69 Darlington Avenue 127 Cardinal Drive Ext. Wilmington, NC 28403 Wilmington, NC 28405 Subject: SR 1403 Middle Sound Loop Road Near Interesection w/ SR 1926 Northbend Road WBS#: 3.206511 (DWQ Permit Fee: $240) Dear Mr. Shaver and Ms. Steenhuis: The North Carolina Department of Transportation recently replaced an existing 24" in diameter by 60' in length RCP at location Lat: 34.26841, Long: -77.78326 on SR 1403 Middle Sound Loop Road where it crosses a UT to Pages Creek (SA; HQW) near the intersection with SR 1926 Northbend Road in New Hanover County. The proposed replacement structure is (1) @ 30" in diameter x 56.5' in length RCP. 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 inverts of the new 30" RCP 6" below the natural streambed elevation would result in a greater than 3 percent pipe slope, causing a high flow erodible condition. NCDOT replaced the pipe leaving approximately 2' of fall on the outlet end to the natural stream grade. Approximately 6 LF of additional riprap is proposed to be placed in the stream channel to protect from fiuther 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.

Source of Map: Natural Resources Conservation Service 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.

Soil Survey Area: New Hanover County, North Carolina Survey Area Data: Version 19, 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—Oct 31, 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.
