MCCRORY GOVERNOR July 23, 201A Mr. Steven Kichefski Asheville Regulatory Field Office US Army Corps of Engineers 151 Patton Avenue, Room 208 Asheville, North Carolina 28801-5006 ANTHONY J. TATA SECRHTARY SUBJECT: Bridge #255 Replacement, SR 1207 (Wood Road), Cleveland County Dear Mr. Kichefski: The North Carolina Department of Transportation requests authorization To replace a deteriorating bridge on SR 1207 (Wood Road) in Cleveland County. NCDOT proposes to replace the existing triple span, 18 foot wide bridge with a 52-foot long, double 8 foot x 8 foot box culvert. Inlet and outlet riprap-faced floodplain benches (�60 feet) will be constructed to maintain `naturaP channel dimensions upstream and downstream of the proposed culvert. Coir fiber matting will be utilized to stabilize the benches. A total of 108 feet of an adjacent side tributary must relocated due to the culvert conshuction. The constructed channel will tie inTo the main channel at the end of the upstream bench. The slope of the side tributary is on a�5.6% slope; therefore, the entire length of the channel will be riprapped. The riprap will be embedded into the new channel (see detail2 on plan sheets) so as not to impede aquatic passage. A temporary diversion channel will be used to manage the stream flow stream around the construction site. Any areas affected by the temporary diversion will be restored To pre-project conditions. The total scope of the work will result in 160 feet of permanent impacts to two unnamed tributaries to Ashworth Creek, which is classified as Class C waters by the N.C. Division of Water Resources. The projecY is not located within'/z mile of any critical watershed azea nor is SR 1207 a rural or urban arterial; therefore, hazardous spill basins are not required. Enclosed is the hazardous spill basin checklist. The proposed project has been submitted/cleared by the cultural resources office. (Project Tracking # ll-10-0017). This office has conducted a threatened/endangered species survey within the project footprint. The federally listed species for Cleveland County (USFWS Listed date September 22, 2010) include dwarf-flowered heartleaf (Hexastylls nan�ora). National Heritage Program records document the nearest hearkleaf location 3.4 miles northwest of the proposed project area. The hearCleaf 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 unpact on this species is anticipated. Bridge #255, SR 1207, Wood Road Page 2 July 23, 2014 I have enclosed a pre-construclion notification for a NW#lA, sketches of planned activities and location maps relative to the project. Project information for fhe 401 Automated Payment Procedure is as follows: • Work order number: 150455-55120005-17BP12.R.102-3372 • TIP#: NA • Project Category: $240.00 Fee If you have any questions or concerns please feel free to contact me at (704) 480-9044.
