Project Description 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The project site is located in the right-of-way of Shadowline Drive owned by the Town of Boone. Watauga County, NC, (see Location Map) Temporary construction easements will be necessary from four adjacent parcels for access to the project area The project site consists of an upstream and downstream portion of an unnamed tributary to Winkler Creek connected by a 104 LF 24" CMP travelling under Shadowline Drive. The existing culvert is undersized causing sediment and debris accumulation at the upstream side leading to a large amount of deposition in the stream channel. Stream degradation has reached approx 40' upstream in the form of incised stream banks and head cutting. Project area includes 50 LF upstream of Shadowline Drive and 40 LF below the existing culvert downstream of Shadowline Drive. The unnamed tributary to Winkler Creek averages 3 ft in width, and 1-2 inches in depth. The surrounding area of the Project Site is commercial land. 3b. List the total estimated acreage of all existing wetlands on the property: WA: 0.053 acres (2322 ft2), WB: 0.003 acres (142 ft2). 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: Project Site encompasses approximately 280 linear feet of a perennial unnamed tributary (UT) to Winkler Creek (of which 104 LF is currently piped through 24" CMP culvert). 3d. Explain the purpose of the proposed project: The purpose of the Project is to install a 48" Steel Casing Pipe to replace an existing undersized 24" CMP. An upgrade in pipe sizing will eliminate sediment and debris accumulation and properly convey stream flows. Shadowline Drive Culvert Installation NWP #3 PCN Application February 10, 2017 Page 4 of 15 3e. Describe the overall project in detail, including the type of equipment to be used: The Shadowline Drive Culvert Installation project includes the bore and jack of approximately 118 LF of 48" Steel Casino Pipe (SCP) for the conveyance of UT Winkler Creek. The existing undersized 24" CMP pipe will be abandoned in place through pumping flowable fill and permanently capping the inlet and outlet. Approx. 40 LF of upstream restoration will be necessary to route the stream into the installed 48" culvert and restore stream channel function which is currently degraded and sediment laden (see Photo Sheets). To complete the project, a temporary 24" pipe will extend from the existing culvert past the construction area (upstream) to prevent sediment impacts to UT Winkler Creek during construction. A 40 FT by 10 FT bore pit will be excavated to house the bore and jack for installing the new 48" SCP. The 48" SCP will be embedded to a death equal to 20% of its diameter (Approx. 10") to allow for the development of natural stream substrate and passage of aquatic organisms. During bore and jack processes it is assumed that the bore pit will fill with water, therefore water will be pumped out of the bore pit, and filtered through a dewatering silt baa. Wattles for turbidity control will be placed between the dewatering silt bag and the stream (see Plan Sheet C-101). Upon completion of bore and jack process, a large boulder grade control, outlet protection structure will be installed on the downstream end of the 48" SCP. The outlet area will be -graded to meet up with the ori-ginal stream channel within 15 LF (see Plan Sheets C-103, C-104, and C-501). All rip rap in this area will be buried and/or'keved in' such that the stream elevation will maintain original flows. Additional boulders and rip rap will be installed on the ri-ght bank at the existing channel below the new pipe outlet. Once the downstream work is completed and stabilized, the 24" diversion pipe will be removed, and the 24" CMP pipe will be abandoned in place by pumping flowable fill and permanently capping both the inlet and outlet. The upstream section of UT Winkler Creek is currently sediment impacted with natural substrate buried due to sediment buildup caused by pipe blockage during storm flows. This section of stream will be impacted by the bore pit and stream diversion and will be restored in the final step of construction to match reference dimensions as well as bank and longitudinal profile slopes typical of streams of the same order magnitude (see Plan Sheets C). Durina restoration, the 24" pipe diversion will be utilized to ensure that all work occurs in the dry. Once stream restoration activities are completed, stream banks will be stabilized with coir matting and a native seed mix. All disturbed areas will be seeded and mulched per the specifications laid out on Plan Sheet G-002. Proposed project actions would temporarily impact 0.01 acres of wetland WA (Impact W-1) during bore pit excavation and 48" culvert installation. Excavated wetland material will be side cast and used as backfill when reestablishing impacted wetland areas. Disturbed wetland areas will be permanently stabilized using mulch and a native seed mix. Proposed project actions will include temporary impacts to UT Winkler Creek. Stream impact S-1 (53 LF) will result from the installation of the bore pit for bore and iack of the 48" culvert, stream restoration, and diversion. Upon completion of bore and lack, the bore pit will be filled with original material and the stream channel regraded to the invert of the 48" pipe (accounting for 20% embedment). Temporary impact S-2 (40 LF) will include installation of grade control and boulder protection below the pipe outlet and on the eroded stream bank below the pipe. Disturbed areas of stream bank will be stabilized following proposed work with coir matting, and temporary erosion control and native seed mix. Typical construction excavation eauipment will be used including a small excavator, trackhoe, and dump trucks. In addition. Bore and Jack will be used to drill culvert underneath of Shadowline Drive.

Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Disturbance is limited to the proposed areas required for culvert replacement. Access roads have been designed to avoid any trees 12" or larger DBH, and temporary devices have been proposed when possible to reduce footprint of project. The new pipe will be installed by the bore and lack method which will greatly reduce impacts to UT Winkler Creek and Shadowline Drive, and reduce project duration. Work will not commence until after the trout moratorium period, ending on April 15. b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Protective temporary diversion pipe will be installed to extend beyond the area of influence of the bore and jack pit to reduce sediment loading into the creek. Additionally, dewatering filter bag will be utilized to filter water pumped from the bore pit during construction. Excavated material from within wetland areas will be side cast and returned to wetland as back fill after pipe installation. 2.

Basis For Determination The site contains wetlands as determined by the 1987 Corps of Engineers Wetland Delineation Manual and the Interim Regional Supplement to the Corps of Engineers Wetlands Delineation Manual: Eastern Mountain and Piedmont Region. These wetlands are adjacent to stream channels located on the property that exhibit indicators of ordinary high water marks. The stream channels on the property are unnamed tributaries to Winkler Creek which flows into the South Fork New River which flows into the New River. The New River is located in the Kanawha Watershed and ultimately drains to the Gulf of Mexico. Specifically, the New River is formed by the joining of the North Fork and South Fork of the New River. The New River drains to the Gauley River and then to the Kanawha River. The Kanawha River drains to the Ohio River then to Mississippi River before entering the Gulf of Mexico. D. Remarks: The site visit was conducted on February 5, 2014 with John Vilas (ENV). Waters and wetlands are accurately depicted on the map labeled Shadowline, Inc. Delineation Map, dated March 20, 2014. The site include approximately 5421ft of a perennial an unnamed tributary to Winkler Creek and 0.12 acre of wetlands. E.
