RE: Response to MY4 Draft Report Comments
Vile Creek Mitigation Project
DMS Project # 96582
Contract Number 5999
New River Basin - HUC# 05050001 - Alleghany County, North Carolina
Dear Mr. Tsomides:
Wildlands Engineering, Inc. (Wildlands) has reviewed the Division of Mitigation Services, (DMS) comments
from the Draft Monitoring Year 4 report for the Vile Creek Mitigation Project. DMS comments are noted
below in bold, Wildlands responses to DMS report comments are noted in italics.
DMS Comment: Please update the asset tables to reflect the current reporting format (Project
Components, Length and Area Summations, and Overall Assets Summary).
Wildlands, response: The project components and mitigation credits table were revised to reflect the
current reporting format (Table 1).
DMS Comment: Wildlands notes up to 12 bankfull events and up to 16 geomorphically significant
events for 2020 across the site. While it was a wetter than normal year, is there an explanation of
why such an unexpected number of apparent bankfull/geomorphic events occurred in 2020? Please
consider confirming bankfull elevations in the field in MY5 due to so many recorded events.
Wildlands, response: The top of banks and eye bolt elevation were surveyed at each stream's crest gage
during MY4. The crest gages were also resurveyed during the MY4 so a shift in elevation that effected
the whole project during the monitoring year is unlikely. During the stream survey in MY5 and
corresponding data will be adjusted if necessary, Wildlands will confirm bankfull elevations in the field.
The only current explanation for the abundance of bankfull/geomorphic events that occurred in 2020 is
the wetter than normal year. Wildlands' noted similar occurrences of above average
bankfull/geomorphic events throughout most, if not all, of our NC monitoring projects during 2020.
DMS Comment: Please double -side the final hard copy pages.
Wildlands, response: Wildlands has double -sided the final 8 %" x 11' hard copy pages.

Digital Support File Comments
DMS Comment: Last year DMS requested updated spatial features. The digital submittal addressed all
reaches and wetlands, except for UT1 Reach 1. The feature for UT1 Reach 1 does have a length that
matches the "As Built Footage/Acreage" column (1114 ft), but not the "Creditable As Built
Footage/Acreage" column (1088 ft). The notes state that the 25 ft differences between these 2
columns is due to the easement break, which is excluded in the digital submittal, but the feature is
still 1114 ft. Please update the feature to address this difference, or indicate why the feature is
different from the Creditable As Built Footage/Acreage column.
Wildlands, response: The current lengths for UT1 Reach 1 in the digital submittal shopefile are correct.
The issue is that the "As Built Footage/Acreage" and the "Creditable As Built Footage/Acreage" for UT1
Reach 1 in the Baseline Report were incorrectly reported in Table 1 and were subsequently carried
forward and reported incorrectly in MY1 — MY4's draft report. The correct lengths should have been
reported in the baseline reports as 1,139 for the "As Built Footage/Acreage" and 1,114 for the Creditable
AS Built Footage/Acreage'which excludes the 25 foot easement crossing break. Since the Project
Components and Mitigation Credits Table in the Final MY4 Report has been reformatted, the listed
lengths of 1,114 in the AS Built Footage/Acreage column is correct.
DMS Comment: If available, please include features that connect the creditable stream reaches (e.g.
stream segments in easement breaks). DMS wants to be able to have segmented, but continuous
stream shapes within a project's footprint.
Wildlands, response: Wildlands updated the shape file to include the stream segments in easement
breaks. The updated shape file is provided with the digital submittal data.
Enclosed please find two (2) hard copies and one (1) electronic copy on CD of the Final Monitoring
Report. Please contact me at 704-332-7754 x101 if you have any questions.

EXECUTIVE SUMMARY
Wildlands Engineering, Inc. (Wildlands) completed a full -delivery stream and wetland mitigation project
at the Vile Creek Mitigation Site (Site) for the North Carolina Division of Mitigation Services (DMS) to
restore and enhance a total of 8,056 linear feet (LF) of perennial and intermittent stream and to restore
6.40 acres of riparian wetlands in Alleghany County, NC. The Site is expected to generate 5,053.000
stream mitigation units (SMUs) and 5.703 riparian wetland mitigation units (WMUs) for the New River
Basin (Table 1). The Site is located approximately one mile east of the Town of Sparta, NC in the New
River Basin eight -digit Hydrologic Unit Code (HUC) 05050001 and the 14-digit HUC 05050001030020
(Figure 1). The Site streams consist of Vile Creek and five unnamed tributaries (UT) to Vile Creek
including UT1, UT1b, UT1c, UT2, UT3, and a portion of Little River (Figure 2). Vile Creek flows into Little
River near the downstream project boundary. The land adjacent to the streams and wetlands is
primarily maintained cattle pasture and forest.
The Site is within a Targeted Local Watershed (TLW) identified in the New River Basin Restoration
Priority (RBRP) plan (NCDENR, 2009). The Site is also located within the planning area for the Little River
& Brush Creek Local Watershed Plan (LWP). The LWP identified the following stressors to watershed
function: Heavily grazed deforested buffer, livestock access to the streams, heavily eroded stream
banks, land -disturbing activities on steep slopes, non -point source pollution from the Town of Sparta
and surrounding areas, and drained and deforested wetland areas (NCDENR, 2007).
The project goals defined in the Mitigation Plan (Wildlands, 2016) were established with careful
consideration of goals and objectives that were described in the RBRP and to meet DMS mitigation
needs while maximizing the ecological and water quality uplift with the watershed. The project goals
established in the Mitigation Plan focused on permanent protection for the Site, re-establishing natural
hydrology and vegetation, reducing water quality stressors, and enhancing terrestrial and aquatic
habitat.
The Site construction and as -built survey were completed in February 2017. Monitoring Year (MY) 4
assessments and Site visits were completed between April and November 2020 to assess the conditions
of the project.
Overall, the Site has partially met the required stream, vegetation, and hydrology success criteria for
MY5 and is on track to meet MY7 performance standards/success criteria. All restored and
enhancement I streams are geomorphically stable and functioning as designed. During MY4, 9 bankfull
events were recorded on Vile Creek Reach 2 and 7 bankfull events were recorded on UT1 Reach 2.
However, bankfull event criteria was already met in MY2. Multiple geomorphically significant events
were recorded on Vile Creek Reach 2 and UT1 Reach 2. Pebble counts reflect no significant change in
restoration and enhancement I stream substrate material. All ten gages in the wetland re-establishment
and rehabilitation areas are either meeting or exceeding hydrology success criteria.
Invasive species continue to be present within and around the site. Currently, 11.6 % of the conservation
easement contains an invasive species population. Treatments performed in September MY4 will be
evaluated in MY5.

Section 1: PROJECT OVERVIEW
The Site is located approximately one mile east of the Town Sparta in eastern Alleghany County, NC. The
project is within the New River Basin eight -digit HUC 05050001 and the 14-digit HUC 05050001030020
(Figure 1). Located in the Blue Ridge Belt of the Blue Ridge Province (USGS, 1998), the project watershed
primarily includes managed herbaceous, mixed upland hardwoods, and other forested land. The
drainage area for the project streams range from 0.01 square miles to 2.69 square miles.
The project streams consist of Vile Creek and five unnamed tributaries (UT) to Vile Creek including UT1,
UT1b, UT1c, UT2, UT3, and a portion of Little River. Stream restoration reaches include Vile Creek
(Reaches 1 and 2) and UT1 Reach 2, which together comprise 3,047 linear feet (LF) of perennial stream
channel. Stream enhancements reaches include UT1 Reach 1, UT1b, UT1c, UT2, UT3, and a portion of
Little River, totaling 5,009 LF. Wetland components include 3.02 acres of wetland rehabilitation and 3.38
acres of wetland re-establishment.
Construction activities were completed by Land Mechanic Designs, Inc. in February 2017. Planting and
seeding activities were completed by Bruton Natural Systems, Inc. in February 2017. The land required
for construction, management, and stewardship of the mitigation project included portions of five
parcels resulting in 25.04 acres of the conservation easement. The project is expected to generate
5,053.000 stream mitigation units (SMUs) and 5.703 riparian wetland mitigation units (WMUs). Annual
monitoring will be conducted for seven years with close-out anticipated to commence in 2024 given the
success criteria are met.
1.1 Project Goals and Objectives
The Site is intended to provide numerous ecological benefits within the New River Basin. While many of
these benefits are limited to the Vile Creek project area, others, such as pollutant removal, reduced
sediment loading, and improved aquatic and terrestrial habitat, have farther -reaching effects. Expected
improvements to water quality and ecological processes are outlined below as project goals and
objectives. These project goals and objectives were established with careful consideration of goals and
objectives that were described in the RBRP and to address stressors identified in the LWP.
The following project specific goals established in the Mitigation Plan (Wildlands, 2016) include:

project are prevented.
1.2 Monitoring Year 4 Data Assessment
Annual monitoring and quarterly Site visits were conducted during MY4 to assess the condition of the
project. The stream, vegetation, and hydrologic success criteria for the Site follows the approved success
criteria presented in the Vile Creek Mitigation Plan (Wildlands, 2016).
1.2.1 Stream Assessment
MY4 is a reduced monitoring year that does not require morphological surveys; therefore, no cross -
sectional survey was performed this year. Pebble counts were conducted in MY4 and found no
significant change in stream bed material throughout the site.
1.2.2 Stream Hydrology Assessment
At the end of the seven-year monitoring period, two or more bankfull events and geomorphically
significant (60% of bankfull flow) events must have occurred in separate years within the restoration and
enhancement reaches.
During MY4, Twelve bankfull events and sixteen geomorphically significant events were documented on
UT1 Reach 2, while nine bankfull events and fourteen geomorphically significant events were
documented on Vile Creek Reach 2. With at least three bankfull events occurring in separate years
documented on UT1 Reach 2 and at least two bankfull events occurring in separate years documented
on Vile Creek, the success criteria for bankfull and geomorphically significant events has been met on all
monitored reaches.
Refer to Appendix 5 for hydrology summary data and plots.
WVile Creek Mitigation Site
Monitoring Year 4 Annual Report — Final 1-3
1.2.3 Vegetative Assessment
MY4 is a reduced monitoring year that does not require detailed vegetation inventory and analysis;
therefore, no vegetation plot monitoring was performed this year. Visual assessments in MY4 indicate
isolated areas on -site are exhibiting low stem heights and vigor. See the Adaptive Management Section
below for more detail.
Refer to Appendix 2 for vegetation plot photographs.
1.2.4 Wetland Assessment
A total of ten groundwater hydrology gages (GWG) and two soil temperature gages were established
during baseline monitoring within the wetland rehabilitation, wetland re-establishment, and bog areas.
A barotroll logger, used to measure barometric pressure and aid in the calculation of groundwater
levels, was also installed on -site. Groundwater monitoring gages are downloaded on a quarterly basis
and maintained as needed. Under typical precipitation conditions, the final performance success criteria
for groundwater hydrology is the documentation of free groundwater within 12 inches of the ground
surface for 14 consecutive days (8.5%) of the defined 169-day growing season (April 26 — October 11) for
wetlands and 20 consecutive days (12%) of the defined 169-day growing season (April 26 — October 11)
for bog areas.
All the Site's GWGs met the success criteria for MY4, with the measured hydroperiod ranging from 26%
to 100% of the growing season. The attainment criteria for hydrologic success for all the wells increased
or remained the same in comparison to previous years. A manual measurement of each GWG water
elevation was taken during MY4. GWGS 5 and 9 show inconsistencies with the manual measurement
and the barotroll gage data. Multiple manual measurements will be conducted at each GWG in MY5 to
further evaluate any inconsistencies in data.
Rainfall data collected from the NC-AG-1-Sparta 3.5 SSW(NCCRONOS) rain gage, showed average to
above average rainfall for a majority of the growing season. Refer to the CCPV Maps in Appendix 2 for
the groundwater gage locations and Appendix 5 for groundwater hydrology and average rainfall
summary data and plots.
1.2.5 Areas of Concern/Adaptive Management Plan
Overall, the streams are geomorphically stable and riparian and wetland vegetation is performing well.
However, isolated stream and vegetation problem areas do exist on -site. The following areas are
experiencing localized bank instability and include: Vile Creek Reach 1 station 103+90-104+20, Vile Creek
Reach 2 stations 118+50-118+80, 120+70-121+00, and 122+80-123+00, UT1 Reach 1 station 206+40-
206+60, UT2 stations 305+00-305+50, 306+30-306+70, and 310+00-310+15. Localized areas of
aggradation along enhancement II reaches, UT2 (Stations 309+70 (32'), UT1b (station 251+20 (51')), and
UT1c (Station 271+50 (115')), have resulted in sheet flow onto the floodplain rather than maintaining flow
within a single thread channel. The stormwater best management practice (BMP) at the top of UT2 has
formed a headcut at the intake from a natural crenulation flowing into the BMP. An area of instability
along UT1 Reach 1 (Station 205+10-205+60) that was previously mention in the MY3 report, naturally
realigned itself (Approximately 21-feet) in MY4; thereby, abandoning an existing meander bend and
creating an ox bow. The newly created channel appears to be stable and will be closely monitored for
instability. If necessary, soil amendments and live stakes will be added to the abandoned oxbow channel,
see areas of concern photos 7 & 8. Stream structures currently failing include: Log sill UT1 Reach 1 station
204+90, Rock Sill UT1 Reach 2 station 220+98, and Log sill Vile Creek Reach 1 station 104+10. Wildlands
plans to address areas of localized bank instability across the Site and further evaluate headcut/s,
structure failures, and aggradational areas of concern during winter 2020/2021. All completed repairs will
be included in MY5 monitoring report.
WVile Creek Mitigation Site
Monitoring Year 4 Annual Report — Final 1-4
The headcut at the intake of the BMP located at the top of UT2 was repaired with hand tools and live
stakes in March of 2020. The live stakes have started taking root; however, further repairs will be
needed to fix the headcut. In addition, a large undercut bank was repaired with live brush on UT2 at
station 306+30. These repairs will be further evaluated during MY5 site walks.
Though invasive species, including Japanese barberry (Berberis thunbergii), Oriental bittersweet
(Celastrus orbiculatus), and multiflora rose (Rosa multiflora) continue to be present within and around
the Site, previous invasive species treatments of cutting the plants and applying glyphosate to the
stumps or stems have reduced their populations from 13.2% in MY3 to 11.6% in MY4. Invasive
treatments were also conducted in September of MY4 and included spraying all fence lines and UT3 for
barberry. Although the presence of invasive species are not impacting survival rates of planted stems at
this time, these areas will likely warrant additional treatment to prevent any advancement within the
conservation easement and future impacts to the Site. Wildlands will continue to monitor the areas of
concern and take action as necessary.
Less than 1% of the easement contains areas of poor herbaceous cover. These areas are located
between GWGs 8 and 9, along the right bank of UT2 near station 305+00, and along the left bank
boulder toe on Vile Creek Reach 3 between stations 124+00 and 124+50. Although, these areas were
reseeded in June of MY3 and are starting to establish herbaceous vegetation, these areas were still
included MY4 as exhibiting poor herbaceous cover.
During winter MY3 and MY4 areas of low stem density and height were documented on site and amount
to 18.2% of the planted conservation easement. These areas include: A portion of the left floodplain on
UT1 Reach 1, an area along the right floodplain of UT1C, which continues downstream to Vile Creek
Reach 2, and along the left floodplain of UT2 just below the BMP. Supplemental planting of 300 1-gallon
trees were completed in the spring of 2020 on the right bank UT1 R2 starting at UT1C and continuing
down to Vile Creek Reach 2. Elderberry plugs were also planted along UT1 as streamside plantings to
further shade out the stream. All of the 1-gallon plantings were considered unsuccessful because the
deer population located on -site are grazing the tops off newly planted stems; therefore, causing a
mortality rate of greater than 50% of the supplementally planted stems. A second supplemental planting
in this area, as well as along the left floodplain of UT1 Reach 1 is proposed. Installation will be planned
when nursery stocks of deer resistance plant material becomes available.
Easement encroachment from mowing on the left floodplain of UT1 Reach 1 continues to be an issue. In
MY4, Wildlands further delineated the easement boundary in this area with additional signs. The
additional signs installed along the boundary helped reduce the mowing encroachment but did not
eliminate it. Wildlands will add additional signage between existing posts to help continue reduce
mowing within the easement.
Refer to Appendix 2 for the vegetation condition assessment table, the CCPV maps, and area of concern
photos.

1.3 Monitoring Year 4 Summary
The streams within the Site appear to be stable and functioning as designed. Multiple bankfull and
gemorphically significant events were documented for UT1 and Vile Creek; therefore, the site has met
the stream hydrological success criteria. All ten groundwater gages met the success criteria for MY4.
Planned management and maintenance will continue to address any areas of concerns that should
advance or arise.
Summary information and data related to the performance of various project and monitoring elements
can be found in the tables and figures in the report appendices. Narrative background and supporting
information formerly found in these reports can be found in the Mitigation Plan documents available on
DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS
upon request.

Section 2: METHODOLOGY
Geomorphic data were collected following the standards outlined in The Stream Channel Reference Site:
An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration: A Natural
Channel Design Handbook (Doll et al., 2003). All Integrated Current Condition Mapping was recorded
using either a Trimble or Topcon handheld GPS with sub -meter accuracy and processed using Pathfinder
and ArcGIS. Crest gages were installed in surveyed riffle cross sections and monitored quarterly.
Hydrologic monitoring instrument installation and monitoring methods are in accordance with the
United States Army Corps of Engineers (USACE, 2016) standards. Planted woody vegetation is being
monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation
Survey-EEP Level 2 Protocol (Lee et al., 2006).

the North Carolina Department of Environmental Quality (DEQ)
Division of Mitigation Services (DMS) and is encompassed
by a recorded conservation easement, but is bordered
by land under private ownership. Accessing the site
may require traversing areas near or along the easement
boundary and therefore access by the general public is not
permitted. Access by authorized personnel of state and
federal agencies or their designees/contractors involved in
the development, oversight,and stewardship of the restoration
site is permitted within the terms and timeframes of their
defined roles. Any intended site visitation or activity by
any person outside of these previously sanctioned roles
and activites requires prior coordination with DMS.
Directions to Site:
To reach the site from Raleigh, NC, take 1-40 West toward
US70/Greensboro/Winston-Salem. Keep right at the fork to
continue on 1-40 Business West/US-421 North. Take exit 6B for
US-52 North/US-311 North/NC-8 North toward Mount Airy/Smith
Reynolds/Airport. Merge onto US-311 North/US-52 North and
continue to follow US-52 North. Continue on 1-74 West. Take exit 6
for NC-89 toward Mount Airy. At the end of the exit ramp, turn left
onto NC-89 West. Travel 13.7 miles, turn left onto NC-18 South.
Travel 14.4 miles, cross over Vile Creek. Napco Road will be on
the right. Take the next left onto a gravel farm road to access the Site.

On July 18, representatives from Wildlands Engineering met with several members of the Inter -Agency Review
Team and NC Division of Mitigation Services on site to observe and discuss the construction and performance of
the bog habitat built on site. The key topics of the discussion are described below.
Break up flow paths in bog area
The middle bog area on the left floodplain along Vile Creek Reach 1 has some concentrated flow
paths that seem to consistently convey water through the bog. These are a risk for headcutting.
The flow will be dispersed by placing three coir logs across the concentrated flow paths. They
will be staked in place. The coir logs are only intended to be a temporary measure to prevent
erosion until the vegetation becomes fully established. The approximate location for the coir
logs is shown on the attached map.
Lowering of bog area berm
The most downstream bog area has approximately 6 to 10 inches of water backed up behind the
berm (see attached map). This particular berm was constructed slightly too high. Wildlands has
agreed to lower the spillway elevation on this berm by about six inches to reduce the depth of
water ponded behind the berm. This will be done with manual labor in order to minimize the
impacts on the surrounding wetlands and vegetation.
3. Transplant Gray's Lily
Because one or two specimens of Gray's Lily identified on site were graded over during
construction, Wildlands located a source for the flowers to transplant on the site. During the
site visit, a Gray's Lily was found adjacent to a bog area on the left floodplain of Vile Creek Reach
2. U.S. Fish and Wildlife Service representatives asked Wildlands to install the transplants in the
same area as the existing plant. On Thursday, July 20 Wildlands planted three Gray's Lily bulbs
in this location (see attached map).

4. Remove trees from shrub planting zones and replant with shrubs
In a couple of areas along Vile Creek, at least some trees were planted in shrub zones. This is a
problem because the shrub zones were planned to minimize shade on the bog areas. Trees will
create undesirable shade on the bogs. Wildlands will remove the trees from these areas and
replant with shrubs. The primary areas where trees are planted in shrub zones are shown on
the attached map. Action Item: Please review the attached map and coordinate with Jeff
Keaton if there are other areas where trees are planted in a shrub zone. Please also review
the approved planting plan map submitted with the final mitigation plan (also included) to
make sure the any additional areas are within planned shrub zones.
Improve floodplain outlet
At the upstream end of Vile Creek Reach 2, there is a floodplain outlet that is not functioning
properly (see attached map). Most of the water draining out of a nearby bog area is not
entering the channel through the constructed outlet but is draining over a brush toe where the
brush overlaps with the riffle. After some discussion, it seems like the best solution is to
relocate the outlet to the location where the water wants to flow. Wildlands will relocate the
outlet.
6. Meander bend erosion
At the downstream end of Vile Creek Reach 2 there is some erosion beginning on the outside of
a meander bend. The group agreed that this area does not need remedial action at this point
but Wildlands agreed to continue to watch this area going forward. If remedial action becomes
necessary, Wildlands will stabilize the bank and correct the problem.
