Army Corps of Engineers NCDOT Regulatory Project Manager 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 JAMES H. TROGDON, III SECRETARY Subject: Nationwide Permit 14 and 12 Application U.S. 23 Business (N. Main St.) and Walnut St. Round -About Shelton Branch, Haywood County, NC TIP No. U-5888, State Project No. 44625.1.1 Dear Ms. Amschler: The North Carolina Department of Transportation (NCDOT) is requesting authorization for stream and wetland impacts that are necessary for improvements to the intersection U.S. 23 Business (N. Main St.) and Walnut Street in Waynesville, Haywood County, NC. The state funded project involves replacement of a complex signalized intersection with a round -about to improve traffic flow. The work will require stream impacts to accommodate fill slopes, a culvert extension, utility crossings, and stream bank stabilization. Section 7 Carolina northern flying squirrel (Glaucomys sabrinus coloratus), gray bat (Myotis grisescens), Indiana bat (Myotis sodalis), northern long-eared bat (Myotis septentrionalis, NLEB), Appalachian elktoe (Alasmidonta raveneliana), spruce -fir moss spider (Microhexura montivaga), small whorled pogonia (Isotria medeoloides), spreading avens (Geum radiatum), and rock gnome lichen (Gymnoderma lineare) are known from current records and are listed as either threatened or endangered in Haywood County. Shelton Branch flows to Richland Creek, which then flows into Lake Junaluska. There are no known populations of Appalachian elktoe in these waters or in waters downstream of the project area, so there should be no effect of the project on this mussel. The project area is urban and there is no suitable habitat for small whorled pagonia, so the project will have no effect on small whorled pagonia. Mailing Address: Telephone: (828)586-2141 Location: NC DEPARTMENT OF TRANSPORTATION Fax: (828)586-4043 NC DEPARTMENT OF TRANSPORTATION Division 14 Customer Service: 1-877-368-4968 Division 14 253 Webster Road 253 Webster Road Sylva, North Carolina 28779 Webstte: www.ncdot.gov Sylva, North Carolina 28779 U-5888 Haywood County Page 2 May 3, 2019 The project area is too low in elevation or does not have damp rock faces or other habitats that would be suitable for rock gnome lichen, spruce -fir moss spider, spreading avens, or flying squirrel. Gray bats usually roost in caves or in/on structures year-round while Indiana bats and NLEB only winter in caves. 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, or in cavities or under the loose peeling bark of dead trees. This project will require tree removal and culvert demolition, but there are no caves or nearby the project. The potentially roost suitable culverts were inspected for bat usage on multiple occasions with the most recent check being on May 2, 2019. No bats or sign were detected. The project area is not situated in a region (i.e. "red HUC") where there are known NLEB maternity roosts and/or hibernacula and the nearest records are over a mile away. The construction work will require the removal of about 32 trees from the streambanks and yards. There will likely be percussive activities with the project (hoe -ramming and/or jack hammering) to break concrete and install guardrail, but this work should be intermittent and infrequent and limited to a few hours a day in some weeks. There are no areas where bedrock blasting is anticipated. To protect Indiana bats, obstructing trees will be removed between October 15 and April 15 (winter clearing) of any year. With the clearing restriction, a "may affect, not likely to adversely affect" determination for Indiana bat should apply to the project. This tree clearing restriction will protect other potentially roosting bats in the area from direct disturbance as well. Based on this and the preceding information, the project should have "no effect" on gray bats and be compliant with the Final Section 4(d) rule for NLEB, codified at 50 C.F.R. § 17.40(o) and effective February 16, 2016. Section 106 This project was reviewed by NCDOT's Human Environment Unit in 2016-2017 for potential effects to architectural and archaeological resources. There was a determination of "No Effect" for architecture and "No Survey Required" assessment for archaeology. Furthermore, the project area is not in an area known to harbor appreciable intact archaeological resources. Impacts to Waters of the United States Shelton Branch has a well-defined channel and banks. It flows downstream to Richland Creek, Lake Junaluska, and then on to the Pigeon River which meets the definition of a Traditional Navigable Water. Therefore, we believe the affected stream 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 Hiawassee River Basin (HUC 06010106030020). Impacts are listed in the PCN, in the impact summary table on sheet 8 of the attached plans, and summarized in the table below. A PJD has not been requested in accordance with prior Corps guidance since only one potential WOUS feature will be affected. Site Existing Proposed Impact New Permanent Impact 1 2@10'x8'x45' reinforced . 2@11'x9'x89' • 44' culvert concrete box culvert and rip reinforced box culvert extension rap streambank protection with sills and baffles • 120' rip rap benches and stabilization U-5888 Haywood County Page 3 May 3, 2019 • rip rap benching for single cell low flow and bank stabilization. • 3 subaqueous water and sewer lines 2 1@15'x5' bottomless arch . Open channel with 155' rip rap and cross culvert and rip rap cross vane and rip rap vane streambank protection stabilization • 1 subaqueous sewer line Compensatory Mitigation and Plan Compensatory mitigation is not proposed since the permanent stream losses are considered minimal. A NCSAM rating was also completed which returned a "low" rating due to water quality stressors, lacking vegetative buffers, and other factors attributed to this urban area. Permits Requested NCDOT hereby requests authorization under Section 404 of the Clean Water Act to proceed with the construction project outlined above. NCDOT requests authorization for the project under Section 401 of the Clean Water Act from the North Carolina Department of Environmental Quality, Division of Water Resources (DWR). The project area is within a "designated trout watershed" (as described in the Nationwide Regional Permit Conditions) and we would like comments on this request from the NC Wildlife Resources Commission. Please contact me at (828) 586-2141 if you have any questions or need additional information to evaluate this request. Your prompt attention to this request is greatly appreciated. el ed by: 2 v- 5/3/2019 8B673FBE42E5415...
