MCCRORY GOVEAIVOR Jtiily 28, 2014 Mr. Steven Kichefski Asheville Regulatory Field Office US Anny Corps of Engineers 151 Patton Avenue, Room 208 Asheville, North Carolina 28801-5006 ANTHONY J. TATA SECRETABY SUBJECT: Bridge #149 Replacement, SR 1664 (Middle Road), Alexander County Dear Mr. Kichefski: The North Carolina Department of Transportation requests authorization to replace a deteriorating bridge on SR 1664 (Middle Road) in Alexander County. NCDOT proposes to replace the existing single span, 20 fooY wide bridge with a 46-foot long, triple 10 foot x 8 foot box culvert. Inlet and outlet riprap-faced floodplain benches (�60 feet) will be constructed to maintain `naturaP channel dimensions upstreun and downstream of the proposed culvert. Coir fiber matting will be urilized to stabilize the benches. Due to the severe meander in the stream immediately upstream of the proposed culvert, approximately 17 feet of stream channel will be relocated to better align with the culvert and the outside meander bend adjacent to the roadway will be stabIlized with riprap (122 feet). Please note thaY the sixty feet of riprap faced bench impacts and the stream relocation impact on the upstream side is within the 122 feet of bank stabilizarion impacts. It is proposed ThaT the triple barrels of culvert will be constructed in stages and impervious dikes will be utilized to manage the stream flow thtough the barrels during conshuction. Any areas affected by the sTaging and temporary impervious dikes will be restored to pre-project conditions. The total scope of the work will result in 228 feet of permanent impacts to Big Branch, which is classified as a WS-1V watershed by Yhe N.C. Division of Water Resources. The project is not located within'/z mile of any critical watershed area nor is SR 1664 a rural or urban arterial; therefore, hazardous spIll basins are not required. Enclosed is the hazardous spill basin checklist. The proposed project has been submittedlcleared by the cultural resources office, (Project Tracking # 12-09-0053). This oifice has conducted a threatened/endangered species sarvey within the project footprint. The federally listed species for Alexander County (USFWS listed date September 22, 2010) include dwarf-flowered heartleaf (Hexastylis naniflora) and bog turtle (Glyptemys muhlenburgii). Nationa] HeriYage Program records documenY the nearest heartleaf location 113 miles south of the proposed project area. The heartleaf is usually found on dry to moist ravine slopes (usually north facing and of the oak-hickory-pine forest type) and in boggy areas near springheads. There is no suitable habitat in the proposed project area and no heartleaf species were observed within the project footprint No impact on this species is anticipated. Natural Heritage Program records document the nearest bog turtle location appro�mately 9.5 miles north of the proposed proj ect area. Bridge #149, SR 1664, Middle Road Page 2 July 28, 2014 Bog turtles are typically found in bogs, marshes, and wet pastures. There is no suitable habiYat located within the project footprint. T/SA species are not subject to Section 7 consultation; however, no impact on this species is anticipated. [ have enclosed a pre-construction notification for a NW#14, sketches of planned activities and location maps relative to the project. Project information for the 401 Automated Payment Procedure is as follows: • Work arder number: 150465-55120005-17BP.12.R.102-3372 • T1P#: NA • Project Category: $240.00 Fee If you have any questions or concerns please feel free to contact me at (704) 480-9044.
