Subject: [External] USACE authorization of additional work - Watauga Bridge #83 bank failure Kevin, This message concerns the NWP verification letter that the USACE issued for the Bridge No. 83 project in Watauga County (SAW-2019-01984) on October 18, 2019, and your request to repair recent storm damage, as detailed in your email below and in the attachments. One of the activities authorized by this verification letter was placement of 95' of rip rap along the banks of the North Fork New River. Your request concerns placing an additional 15' of rip rap to repair the storm damage. I have coordinated this request with the USACE NCDOT Team Leader (Monte Matthews) and we have determined that the original NWP verification decision by the USACE is still valid in light of this additional work; as such, NCDOT is authorized to place an additional 15' of bank stabilization at the locations shown on the attachment titled "rip rap additional at Watauga bridge #83". Note that all conditions of the NWP VL issued for this project on October 18, 2019, remain valid. No additional work in waters of the U.S. is authorized other than (1) those impacts previously authorized, and (2) those impacts authorized by this email. Please let me know if you have any questions.

Subject: Watauga Bridge #83 bank failure Hey Dave and Lori, Last fall, we completed a bridge project in Watauga County — Bridge #83. Dave, you visited the site with me on 10/17/19. Despite finishing the project late in the year, we were able to get some vegetation growing on the newly sloped banks located upstream of the new bridge. However, a flood in February undermined both banks. As a result, we need to add rip rap to stabilize the banks. We plan to only put rip rap at the toe of the bank, leaving the existing vegetation and coir fiber matting. This will help narrow up the stream channel (mimicking conditions upstream and downstream of the site), and will stabilize the banks against future storm events. Also, since we are only putting rip rap at the toe of the bank, trees and shrubs will hopefully take root on the un-armored portions of the bank and provide shade. I've attached photos of the site —1) a couple months post construction when it was in good shape, 2) after the flood event showing the issue, and 3) a depiction of what we would like to do. I've also attached the 401 permit and the modified 404 (we had a modification to the permit, involving a channel change) for reference. I visited the site and took measurements earlier today, and we are in need of an additional 15 ft of riprap (we will be applying more than that, but from a permit standpoint, we only need 15 ft). I'm not sure if this requires a new permit, a permit modification, or just something to note in your files. The stream is naturally very rocky, and like most high gradient Watauga County streams, the banks are typically hardened by natural rock throughout. We installed a temporary detour pipe where the issue occurred, so much of the natural rock that occurred at the site may have been removed in order to get the pipe in place. That's all to say that the area in question was likely hardened naturally prior to the construction of the project. However, I wasn't around back then, so I do not have photos of the banks pre - construction to support that possibility. I'm more than happy to provide whatever additional information you might need. Also, if I need to fill out a PCN, or other formal process, just let me know. PS — NCDOT has asked me to work form home for the time being, to limit the number of employees in the building. have email access, but best to call my cell if you need to speak to me in person.
