S. Army Corps of Engineers 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 JAMES H. TROGDON, III SECRETARY Subject: Nationwide 14 Pernut Application Replace Bridge 95 on SR 1103 (Anderson Creek Road) over Anderson Creek Graham County State Project No. 17BP.14.R.91 (DWQ Minor Permit Fee $240.00) Dear Ms. Beckwith: The North Carolina Department of Transportation (NCDOT) is proposing to replace bridge no. 95 over Anderson Creek in Graham County. The existing structure will be replaced with a 2@ 7' W x 4'H x 96'L reinforced concrete box culvert (RCBC) on the same location. The culvert will be stage constructed to handle traffic during construction. The culvert slope will be about 4.9%, but sills, distinct base flow and high flow barrels, and native material culvert backfilling will be incorparated to mimic the natural morphology of this relatively steep cobble-bed stream. Enclosed are a PCN application, preliminary jurisdiction form, marked-up plan sheets showing the proposed work and impact sites, a USGS quad map, photographs, and other pertinent project information to assist in your consideration of this request. The U.S. Fish and Wildlife Service and North Carolina Natural Heritage Program databases were checked for records of threatened and endangered species in Graham County. Carolina northern flying squirrel (Glaucomys sabrinus coloratus), spotfin chub (Erimonax monachus), Appalachian elktoe (Alasmidonta raveneliana), Virginia spiraea (Spiraea virginiana), rock gnome lichen (Gymnoderma lineare), northern long-eared bat (Myotis septentrionalis, NLEB), gray bat (Myotis grisescens) and Indiana bat (Myotis sodalis) are listed as either threatened or endangered and are known from current records or anticipated to occur in the county. Appalachian elktoe and spotfin chub only occurs in Graham County in the Cheoah River downstream Lake Santeetlah. Anderson Creek is many miles upstream of the lake and is too small and cold to support mussels. Therefore, the project will not affect these species. Mailing Address: Telephone.• (828)586-2141 Locarion: NC DEPARTMENT OF TRANSPORTATION Fax: (828)586-4043 NC DEPARTMENT OF TRANSPORTATION Division 14 CustomerService: 1-877-368-4968 Division 14 253 Webster Road 253 Webster Road Sylva, North Carolina 28779 Website: www.ncdot.¢ov Sylva, North Carolina 28779 Graham 95 Replacement Page 2 July 6, 2017 Virgnia spiraea also only occurs in Graham County along the Cheoah River downstream Lake Santeetlah. There are no scoured banks or gravel bars at the bridge that could support this plant and it was not seen during the bridge scoping. This project should have no effect on Virgnia spiraea. Gray bats usually roost in caves or in/on structures year-round while Indiana bats and NLEB only winter in caves or mines. During warm seasons Indiana bats and NLEB usually roost on/in structures, under the shaggy bark of live trees such as white oaks, sycamores, and hickories, ar in cavities or under the loose peeling bark of dead trees. This project should not require blasting, but it will require the removal of approximately 6 trees and demolition of an old timber bridge. There was no evidence of bats or roosting on the bridge during the field scoping; absence of bats will be confirmed prior to demolition. The bridge is not situated in a"red HUC" where known NLEB maternity roosts and/or hibernacula are a concern and it is several miles from the nearest "red HUC". To protect Indiana bats, the obstructing trees will be removed from October 15 to April 15 (winter clearing). With the clearing restriction, we recommend a"may affect, not likely to adversely affect" determination for Indiana bat due to the potential loss of roost habitat. The Carolina northern flying squirrel and rock gnome lichen are found in spruce-fir forests and other isolated high elevation locations in western North Carolina. However, rock gnome lichen can occasionally be found at lower elevations in deep river gorges with high humidity or on some vertical rock faces that are periodically wet. The bridge site is much too low in elevation and lacks rock faces and other habitat conditions required by these species. The project is small in scale. Erosion and sedimentation control measures will be used to minimize adverse effects of the work on aquatic habitats. Habitats for listed species appear lacking at the project site and none of the species known from Graham County were observed during field visits. For these reasons and those discussed above, we recommend that a determination of "no effect" on listed species, with exception to Indiana bats, apply to this project. This project was reviewed by NCDOT's Human Environment Unit and it was determined that there are no National Register eligible or listed archaeological resources present. A survey for historic architectural resources was not required. NCDOT best management practices will be used to minimize and control sedimentation and erosion on this project. Impacts to Waters of the United States Anderson Creek (DWQ Class: WS-III) is shown on the USGS topographic map as a perennial stream. It has a well-defined channel approximately 7 feet in width with a substrate of gravel and cobble. Anderson Creek flows about 0.2 mile to Tallulah Creek, which then flows about 4.5 miles to the Cheoah River (upstream of Lake Santeetlah). The Cheoah River meets the definition of a Traditional Navigable Water (TNW). For these reasons, we believe Anderson Creek is a Relatively Permanent Water (RPV� and is under the jurisdiction of the U.S. Army Corps of Engineers. In order to construct the project, it will be necessary to impact waters of the United States in the Little Tennessee River Basin (CU 06010204) as follows: Graham 95 Replacement Page 3 July 6, 2017 Net Site No. Existing Condition Proposed Condition Impacts (feet) 1 Anderson Creek 2@ ��W x 4'H x 96'L RCBC 96 and Bridge 95 Abutments Impervious Dikes and Temporary 2 Anderson Creek Flow Diversions 60 (u and down from erm.

Surface Water Body: 1)Anderson Creek Barrel Height ft : 4 ft. Culvert T e: RCBC Culvert Len th ft 85 ft. +/- Avoidance and Minimization Efforts: Culvert maintains existing stream width and slope with sills and baffles and a floodplain bench through high flow barrel. (Bridge to Culvert) Stream Slope Fish and/or Aquatic Life Passage Existing Average Stream Slope (%): 4.90 % Existing Low Flow Channel Dimensions 9 ft. wide with a flow depth of 0.5 ft. Proposed Culvert Slope (%): 4.90 % in the Stream: Culvert Burial Proposed Culvert Burial Depth (ft): 1.5 ft. Existing Streambed Material: sand, gravel and medium boulders Proposed Low Flow Dimensions 7 ft. wide 0.5' deep Through the Culvert: Proposed Sills/Baffles: 1.5' sills with 6+/- 1.5' baffles in low flow barrel. 2.0' silis at inlet and outlet of high flow barrel. Existing Low Flow Velocities in the Stream (ft/s): 3.4 ft/s ropose ow ow e oci ies roug the Culvert (fUs): 4.2 fUs Alternating Low Flow Sills/Baffles: There will not be alternating sills and baffles as the width of the �ow flow barrel (7 ft.) closely approximates the natural stream width. Culvert/Stream Alignment Stream Patterns Upstream and Downstream None. Structure is in relatively staraight stretch of stream. of the Culvert that Could Affect Fish Passage and Bank Stability: Bed Forms Impacted by Culvert (riffles, Structure is in riffle section of stream. pools, glides, etc.): Low Flow Floodplain Bench Required? Yes Floodplain bench is provided at approach and exit of high flow barrel. This is to help maintain eisting patern and profile of existing (provide justification) stream. Bends at Inlet/Outlet? No (describe culvert alignment with stream) Stream Realignment Necessary? (provide No justification) Bank Stabilization: Standard rip rap bank stabilization is proposed at both the inlet and outlet of the culvert. Rip rap is also proposed for stabilization of the floodplain bench. Outlet Velocities Natural Stream Channel 2-yr Velocity (ft/s): 6.6 ft/s Natural Stream Channel 10-yr Velocity (ft/s): 8.5 ft/s Proposed Culvert 2-yr Outlet Velocity (ft/s): 7.6 ft/s Proposed Culvert 10-yr Outlet Velocity (ft/s): 10.3 ft./s Roadway Geometric Considerations Evaluate/Describe Roadway Geometric Constraints: The existing site and skew of the roadway in relation to the stream does not lend this site to a replacement bridge. A culvert is the most appropriate structure for this replacement.

Based on the information received on June 30, 2017, the impacts are located in CU 06010204 of the Little Tennessee River basin in the Southern Mountains (SM) Eco-Region, and are as follows: Little Tennessee Stream Wetlands Buffer (Sq. Ft.) 06010204 Non- Coastal SM Cold Cool Warm Riparian Zone 1 Zone 2 Ri arian Marsh Impacts g6A R 0 0 0 0 0 j 0 0 (feet acres ; � This impact and associated mitigarion need were under projected by the NCDOT in the 2017 impact data. DMS will commit to implement sufficient compensatory stream mitigation credits to offset the impacts associated with this project as determined by the regulatory agencies using the delivery timeline listed in Section F.3.c.iii of the In-Lieu Fee Instrument dated July 28, 2010. If the above referenced impact amounts are revised, then this mitigation acceptance letter will no longer be valid and a new mitigation acceptance letter will be required from EEP.

NCDOT should confirm that there are no structures impacted and follow the guidance provided in the 1982 Federal Highway Administration (FHWA) Memorandum of Understanding with the Federal Emergency Management Agency entitled "Procedures for Coordinating Highway Encroachments on Floodplains within the Federal Emergency Management Agency (FEMA)", and the September 1992 FHWA NS 23 CFR Part 650A, Transmittal 5. The final modeling does not reflect the constriction occurring at stream station 1002. At this location, the weir flow across the road is constricted between two knolls. Final LOMR modeling to establish flood levels should account for this constriction in the weir flow in order to more accurately derive the base flood elevation. FINAL DETERMINATION: SF-370095 is recommended for approval as an MOA Type 2B. Joh�i D. Brubaker, PE, CFM NFIP Engineer Page 1 of 1 Date
