GOVERNOR - SECRETARY June 3, 2011 Ms. Lori Beckwith, NCDOT Regulatory Project Manager U.S. Army Corps of Engineers 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 Subject: Nationwide 14 Permit Application Modification Action ID No. 2011-00926 DWQ Project No. Certification Not Issued SR-1145, Shoal Creek Road Cherokee County State Project No.: 42550.1..1 Dear Ms. Beckwith: The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade„drain and pave SR 1145; Shoal Creek Road, in Cherokee County. This proposal entails widening and paving the existing gravel road to a standard 18-foot roadway. The original permit application dated December 1, 2010, included the extension and/or replacement of six corrugated metal culverts. Once the project was under construction, it was discovered that we needed to extend two additional pipes, site 7 and site 8. This will increase the total stream impacts from 183 linear feet to 262 linear feet. 1 have enclosed a revised impact table to the PCN application and plan sheets for the two additional culverts, photographs, and a USGS quad map. We propose to install the new culverts slightly below the existing streambed elevation where bedrock is not encountered to minimize impacts to aquatic habitats and allow the existing stream gradient to remain as unchanged as physically possible. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all erosion control measures daily to ensure sedimentation and erosion is being controlled effectively. If the planned devices are not functioning as intended, they will be replaced immediately with better devices. _` + nu Fotik&hit _DMsioi Office- '' Telephone: (828) 586-2141 253 Webster Road, Silva, North Carolina 28779 rax: (828) 586}4043 SR 1145, Shoal Creek Road Page 2 June 3, 2011 Impacts to Waters of the Ueitetl States The unnamed tributary of South Shoal Creek (DWQ Class C; Tr) at site 2 is shown on the USGS topographic map as a perennial stream. The streams at permit sites I, 3, 4 and 7 are not shown on the topographic map. The unnamed tributaries of Rocky Ford Creek (DWQ Class C) at sites 5, 6 and 8 are not shown on the topographic map. The seven unnamed tributaries that are not shown on the USGS map are small, but they have well-defined channels. The channel substrate of the streams to be effected is primarily composed of gravel, sand and silt. All five unnamed tributaries of South Shoal Creek flow into South Shoal Creek within 0.5 mule of the road crossings. South Shoal Creek flows into Appalachia Lake approximately 11.5 to 13.0 miles downstream from sites I and 4 respectively. The three unnamed tributaries of Rocky Ford Creek flow into a larger unnamed tributary within approximately 650 feet of the road crossings. The unnamed tributary then flows approximately 0.5 mile downstream to Rocky Ford Creek. Rocky Ford Creek flows approximately 4.8 miles to Turtletown Creek. In turn, Turtletown Creek flows approximately 10.6 miles to the Hiwassee River. Appalachia Lake and Hiwassee River meet the definition of Traditional Navigable Water. For these reasons, we believe that the unnamed tributaries of South Shoal Creek and Rocky Ford Creek are Relatively Permanent Waters and are under the jurisdiction of the U.S. Army Corps of Engineers. In order to make the needed safety improvements to SR 1145, it will be necessary to impact waters of the United States in the Hiwassee River Basin. Specifically, NCDOT is requesting to replace and/or extend two additional culverts; the proposed modifications are listed below.
