CONTI, JR. 3ECREraRY I1~~~~ The North Carolina Department of Transportation (NCDOT) proposes to remove a broken wingwall, drive sheetpiles and place Class II riprap in the stream to improve severely perched downstream end of an existing culvert in Guilford County. The proposed work is necessary in order to stop severe scouring at the end of the culvert and therefore maintain the structural integrity of the culvert and ultimately improve the roadway. This activity will result in permanent impacts to an UT of Big Alamance Creek. The NCDOT anticipates that the activity will be authorized under Nationwide Permit (NWP) 14. This application is intended as a request for written authorization from the US Army Coppe of Engineers for the Nationwide 14. This package is also being forwarded to the NC Division of Water Quality for authorization as prescribed under General Water Quality Certification 3820. Although the project falls within the Jordan Lake watershed, all work involving buffered area is proposed to be within the existing transportation facility. The following information is being provided to satisfy conditions of the Nationwide Permit and General Water Quality Certification. P.O.
