Section, Site 18A, added to address a slope failure adjacent to stream S113 (US to Beaver Creek). To
prevent further erosion, the installation of a new pipe to carry a portion of S 113 will result in additional
permanent and temporary impacts.
All changes in impacts due to the new pipe and the associated temporary dewatering impacts at Site
18A in the D Section are in red italics. Please see the enclosed revised DMS acceptance letter and
revised permit drawings for Section D.
Summary of R-2915 Jurisdictional Impacts:
Impacts for the overall (Sections A-E) project will include 3.05 acres of permanent wetland impacts,
0.28 acre of temporary wetland impacts, and 0.05 acre of hand clearing in wetlands. There will also be
9,467 linear feet of permanent stream impacts (7,805 linear feet of fill and 1,662 linear feet of bank
stabilization), and 0.46 acre of temporary stream impacts (see Tables 1 and 2 for a breakdown of impacts
by Section).

Permit Site 18A:
In 2021, a landowner alerted NCDOT maintenance staff of an issue adjacent/left of approximate Sta.
610+00 within Section D of R-2915 in Ashe County. Maintenance staff visited the site and reported a
long section of deeply incised and actively eroding stream bed. In addition, a large "island" of mature
trees on the slope was starting to slide because of the eroding stream. If this continues, the road shoulder
may collapse and cause a partial loss of the roadway. The area containing the issue is entirely within
NCDOT right of way, but is heavily wooded and did not receive any ground disturbance during
R-2915 Individual Permit Modification Application Page 6 of'8
construction of the D Section. Furthermore, the area of concern is below the roadway, so is completely
out of view to regular NCDOT maintenance activities. As a result, it may have occurred many years
ago. In contrast, the upper portion of the stream that is visible beside R-2915D is in good shape.
It was determined that the stream used to flow into a system of 12" corrugated metal pipes (CMPs) that
measured 113' in length (date of installation unknown, but pre-R-2519D), that carried the UT down a
steep rocky slope into the wooded ravine below, where the stream was once again free flowing. Pieces
of this pipe system are now separated and washed downstream, and the stream now flows down the
rocky slope. However, the area flowing over the steep hillside is in good shape/stable and has
naturalized with mosses, ferns, etc. As a result, NCDOT will leave this previously piped area unpiped,
to remain as daylighted stream reach. The erosion issue begins where this stream hits the valley floor.
There is a deeply incised stream section (20' deep in some places) that extends for approximately 320'.
This reach becomes less incised, and contains less erodible riparian area as you progress downstream.
As mentioned, a section of the adjacent hillside including trees is starting to slide.
To address this issue, NCDOT will install a temporary dewatering pipe that will start at the top of the
hillside beside R-2915D, and carry the stream along the right of way fence and back into the existing
stream channel directly below the proposed reach to be piped. This will result in 450 linear feet of
temporary dewatering. The 320' long incised portion of stream channel with then be filled with rock
and soil, and a series of four 36" high density polyethylene (HDPE) pipes will be buried near the surface
of this new fill. While the proposed pipes are all at a 10% grade, three drop inlets (spaced every 100'
along the pipe system) will be installed to reduce velocity, and convey runoff from the wooded hillside
along R-2915D and the large grassy field on the other side of the project into the pipe system. Along
with the proposed drop inlets, existing instream rock at the proposed outlet of the pipe system will
further help reduce the chances of scour. As mentioned, a previous pipe system (estimated to be a 113'
x 12" CMP) used to carry water down the steep slope to where this new pipe system will begin. We
will leave this area unpiped, and install an open throat catch basin at the start of the new pipe system,
which will collect the stream flowing down the steep slope and convey it into the new HDPE pipe. Once
complete, the stream will be turned into the new system and the temporary dewatering pipe will be
removed. All disturbed ground will be seeded and stabilized.
While piping a stream is not typically environmentally favorable, the existing stream condition is in very
poor shape (with a low NCSAM rating) and actively eroding. Furthermore, while we can't say the R-
2915D project, or historical work on HWY 221, didn't in some way cause all or part of this issue,
discussions with past staff have suggested that this stream section has been in poor shape for > 20 years.
As mentioned, one entire side of the UT is a large pasture with a couple houses and little to no riparian
area, and washouts on that side of the stream suggest high levels of runoff into the stream from that
direction. As such, it is plausible that historical issues (logging/clearing/development) not entirely
related to NCDOT may have in some ways resulted in the current situation.
The proposed work should drastically improve downstream conditions by removing additional sediment
from the stream, and should fix a hazardous situation regarding the potential loss of the roadway to a
future storm event. Furthermore, given the limitations within our right of way and possible solutions, a
better fix to the problem is not readily available.
Total impacts at this new site due to this modification are 320 linear feet of permanent stream impacts
due to the new pipe and 0.04 acre (450 lfi of temporary impacts to stream S113 (UT to Beaver Creek
Creek). *Of note, 320 linear feet of the temporary impacts to S113 overlap with the permanent
impacts, meaning that the dewatering activities only add 130 linear feet of impacts to the cumulative
total

MITIGATION
At this time, DMS is providing compensatory mitigation for all impacts. An additional 320 linear feet
of mitigation within the D Section is required due to the new pipe installation at Site 18A (described
above). Please see the revised DMS acceptance letter for the D Section dated April 7, 2022. Table 5
summarizes the total mitigation needs as 3.05 acres of wetland impacts and 7,805 linear feet of stream
impacts.

Dear Mr. Harris:

Subject: DMS Mitigation Acceptance Letter:
R-2915D, US 221 Widening from South of NC 194 to US 211 Bypass, Ashe County
References: USACE 404 Individual Permit issued January 7, 2015 (USACE Action ID 2012-00882)
NCDWR 401 Water Quality Certification issued September 8, 2014 (NCDWR ID
2014-0762)
The purpose of this letter is to notify you that the Division of Mitigation Services (DMS) will provide
the additional compensatory wetland mitigation for the subject project. Based on the information supplied by
you on April 6, 2022, the impacts are located in CU 05050001 of the New River basin in the Northern

*NOTE: Some of the stream impacts may be proposed to be mitigated at a 1:1 mitigation ratio. See permit application for details.
This additional impact and associated mitigation needs were not projected by the NCDOT in the 2022
impact data. DMS is currently providing stream and wetland mitigation for the impacts associated with this
project located in cataloging unit 05050001 of the New River basin as required by the 404 and 401 permits
issued in January 2015 and September 2014, as shown in the below table (in mitigation credits)

DMS will provide the amount of mitigation as determined by the regulatory agencies.
DMS commits to implementing additional 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
