TENNYSON Secmmry I have enclosed a set of plans, a PCN application for NWP #14, and a vicinity map relative to the proposed bridge replacement project on SR 1397 Surrett Cove Road, Buncombe County, NC. We propose to replace the existing 28' timber/steel bridge with a double barrel box culvert (2@ 10' x 4') with low flow barrel and sills. Stream slope at the site is 3.00%. Culvert installation will result in permanent impact to 52 linear feet of Bald Fork Creek; floodplain bench construction will pennanently impact an additional 83 linear feet. Temporary impacts to 130 feet of the stream are necessary for dewatering and an onsite detour culvert. The stream is approximately 10 feet wide with a predominately gravel/cobble/boulder substrate. Bald Fork Geek is classified as Class C. Existing channel morphology will be maintained upstream and downstream of the culve�rt. Riparian vegetation will be reestablished along disturbed areas associated with the project. Stonnwater will be diverted through grass-lined ditches or vegetated buffers prior to entering streams. This project may impact potentially suitable northern long-eared bat (Myotis septentrionalis) (NLEB) summer roosting habitat via bridge and tree removal. Therefore, a may affect, not Iikely to adversely affect is requested for the NLEB. Minor tree clearing will be performed for the project. The existing bridge is constructed of steel and timber. The crown to bed measurement (distance from travel surface to streambed) is 5 feet. Clearance between the bottom of the bridge and the stream surface is approximately 2-3 feet. A survey of the bridge did not reveal any evidence of usage by bats. For the proposed action, NCDOT has committed to the conservation measures listed below: !`/'Nothing Compares�- S�a�e of Noith Ca�olinn I Depm1menl ofTrensporla�ion I Di ision Thi�teen 55 Orenge S�ae� � PO Box i2]9 � Ashe�ille, NC 28802-3279 828 251 GI71 '1' Ms. La�i Qeckwith Page —2 [3ridge 100677, [3uncombe County �ebrua�y 29,2016 I) No alterations of a known hibernaculum's entrance or interior environment if it impairs an essential behavioral pattern, including sheltering No�rthern long-eared bats (January I through December 31); 2) No tree removal within a 0.25 mile radius of a known hibernacula (Jauuary I through December 31); and 3) No cutting or destroying a known, occupied maternity roost tree, or any other trees within a I50-foot radius from the known, occupied maternity U�ee during the period from June 1 lhrough and including July 31. NCDOT has determined that the proposed action does not require separate consultation on the grounds that the proposed action is consistent with the final Section 4(d) rule, codified at 50 C.F.R. § 17.40(0) and effective February 16, 2016. Section 7 responsibilities are therefore considered fiilfilled. No effect on tl�e remaining Buncombe Counry list of federally protected species (threatened or endangered) or designated critical habitat will occur. Andrew Henderson of US Fish and Wildlife Service is copied on the application for review. As a pait of the 401 Certification process, the project was processed through the D07' Programmatic Agreement for Minor Project as required by Section 106 of the National Historic Preservation Act of 1966 and GS 121-12(a). No Historic Resources will be affected. Qy copy of this letter, we request Marla Chambers, North Carolina Wildlife Resow�ces Commission Western Region Coordinator, to comment directly to the Corps eoncerning the permit request. By copy of this letter, we are asking the Area Roadside Field Operations Engineer, to comment on the above project. Bald Fork Creek is classified as Class C. The project will not require a trout buffer variance. By copy of this letter, I am forwarding one electronic copy of the application package to Kristi Lynn Carpenter, NC Division of Water Resources, Transportation PermitCing Unit with ec to Kevin Barnett, NC DWR Asheville Regional Office for review and comment. Please charge the application fee of $240.00 to WBS element # 17BP.13.R.151. Please forward comments directly to the Corps with copy to Division 13 Enviromnental Officer.

File no. and date of response letter: � Other information (please specify): 1. The Corps of Engineers believes that there may be jurisdictional waters of the United States on the subject site, and the permit applicant or other affected party who requested this preliminary JD is hereby advised of his or her option to request and obtain an approved jurisdictional determination (JD) for that site. Nevertheless, the permit applicant or other person who requested this preliminary JD has deciined to exercise the option to obtain an approved JD in this instance and at this time. 2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General Permit (NWP) or other general permit verification requiring "pre-construction notification" (PCN), or requests verification for a non-reporting NWP or other general permit, and the permit applicant has not requested an approved JD for the activity, the permit applicant is hereby made aware of the following: (1) the permit applicant has elected to seek a permit authorization based on a preliminary JD, which does not make an official determination of jurisdictional waters; (2) that the applicant has the option to request an approved JD before accepting the terms and conditions of the permit authorization, and that basing a permit authorization on an approved JD could possibly result in less compensatory mitigation being required or different special conditions; (3) that the applicant has the right to request an individual permit rather than accepting the terms and conditions of the NWP or other general permit authorization; (4) that the applicant can accept a permit authorization and thereby agree to comply with all the terms and conditions of that permit, including whatever mitigation requirements the Corps has determined to be necessary; (5) that undertaking any activity in reliance upon the subject permit authorization without requesting an approved JD constitutes the applicanYs acceptance of the use of the preliminary JD, but that either form of JD will be processed as soon as is practicable; (6) accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps permit authorization based on a preliminary JD constitutes agreement that all wetlands and other water bodies on the site affected in any way by that activity are jurisdictional waters of the United States, and precludes any challenge to such jurisdiction in any administrative or judicial compliance or enforcement action, or in any administrative appeal or in any Federal court; and (7) whether the applicant elects to use either an approved JD or a preliminary JD, that JD will be processed as soon as is practicable. Further, an approved JD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331, and that in any administrative appeal, jurisdictional issues can be raised (see 33 C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary to make an official determination whether CWA jurisdiction exists over a site, or to provide an official delineation of jurisdictional waters on the site, the Corps wili provide an approved JD to accomplish that result, as soon as is practicable. This preliminary JD finds that there "may be" waters of the United States on the subject project site, and identifies all aquatic features on the site that could be affected by the proposed activity, based on the following information: IMPORTANT NOTE: The information recorded on this form has not necessarilv been verified bv the Corps and should not be relied uaon for later iurisdictional determinations.

Miles Culvert Width/Diameter (ft): 10 Surface Water Body: (1)Bald Creek Culvert Height (ft): 4 Culvert T e: Concrete Box Culvert Culvert Length (ft) 52 Avoidance and Minimization Efforts: The proposed culvert has two barrels with one functioning as a low flow barrel. As such, under low flow (bankfull) conditions, the existing stream (Bridge to Culvert) is approximately 17 feet in width whereas the low flow culvert opening is only 10 feet in width. This results in a somewhat higher velocity in the culvert at the upstream end. However, at the downstream end of the culvert, the backwater from the 60" pipe downstream results in a proposed outlet velocity that is less than existing. The proposed culvert slope is flatter than existing to reduce outlet velocities and minimize erosion.

Culvert/Stream Alignment Stream Patterns Upstream and NA Downstream of the Culvert that Could Affect Fish Passage and Bank Stability: Bed Forms Impacted by Culvert (riffles, NA pools, glides, etc.): Low Flow Floodplain Bench Required? Yes Culvert overtops at less than 5 year event. Floodplain bench has been provided to separate low flow and high flows through the (provide justification) two culvert barrels. The low flow event is the flow which resulted in 1 foot of depth at the upstream end of the low flow culvert Sharp Bends at Inlet/Outlet? Yes Inlet to the culvert has a sharp bend, hence extended wing walls are proposed to channelize water and prevent erosion. describe culvert ali nment with stream Stream Realignment Necessary?
