Dear Mr. Tsomides:
As a reminder, monitoring providers are responsible for checking the easement integrity across the
project site for encroachments, missing markers, fence breaks, etc. Please confirm that the site was
checked and what the results are.
Wildlands Response: The Site was monitored for easement integrity in MY6. One easement encroachment
was observed along the upstream section of UT1. Wildlands was informed of additional issues after a DMS
easement inspection of the Site on October 12, 2022. In reference to listed action items, monument caps
with missing markings will be stamped in MY7 by the contracted surveyor per agency requirements.
Wildlands will repair damaged fencing along UT1 Reach 2 and the damaged sign along UT1c. There was
no vegetation trimming observed around the mobile deer stand in the easement along Vile Creek Reach 2
and no damage due to easement access. An explanation of UT1 and UT2 easement concerns is available
in the comment response below. Wildlands will continue to closely monitor these areas and conduct
detailed easement inspections in MY7. Refer to Appendix 2 for encroachment details and Appendix 6 for
email correspondence.
DMS' Comment: Thank you for summarizing the UT1 easement encroachment and planning additional
marking efforts to rectify the scalloping/mowing; however DMS is concerned that this continues to be
an issue headed into the final monitoring year, and during DMS site visit October 2022 it was evident
that the area is still being mowed. As a reminder, all encroachments and property issues need to be
resolved adequately in order for the project to be a) accepted into DEQ stewardship and b) closed by
the IRT. Have marking measures and landowner contact been completed yet? If possible please provide
a few photos of the area that has been a concern, showing the marking measures taken (or planned),
and please keep a close eye on this area (and the newly marked section along UT2) over the next 6-12
months to ensure that the landowner(s) are heeding the signage and avoiding those areas. In addition
please evaluate and advise on whether WEI feels additional plantings are warranted in this area.
Wildlands Response: Wildlands installed additional signage and horse tape in January 2023 to clearly mark
the boundary of the easement along UT1. The area will be replanted along with scheduled UT1
supplemental planting before the 2023 growing season. Wildlands investigated potential encroachment

along the left bank of UT2 in January 2023. Pasture mowing appeared to be up to the easement line and
no encroachment was observed. The landowner was notified, and additional signage will be added in MY7.
The mobile deer stand was located outside of the easement. Photograph of UT1 available in Appendix 2.
At the 2022 credit release IRT meeting, WEI noted that UT2 will be supplementally planted in the
future. The CCPV did not reflect any supplementally planting along UT2. Please advise or clarify.
Wildlands Response: Additional supplemental planting will occur before the onset of the 2023 growing
season in low stem density areas on Site (approximately 1 acre) including an area along the left bank of
UT1, and upstream sections of UT2. The areas will be replanted with one, three, and/or five -gallon
containerized trees. Species will include those approved in the Vile Creek Mitigation Site Final Mitigation
Plan and 2021 Vile Creek Mitigation Site Adaptive Management Plan (Wildlands 2016, 2021). The
planted species, sizes, wetland indicator status, and quantities will be documented in the MY7
monitoring report. Refer to CCPV Figures 3.1 and 3.3 in Appendix 2 and Section 1.2.5 for supplemental
planting locations and low stem density acreages.

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 (DIMS) 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) 6
assessments and Site visits were completed between April and October 2022 to assess the conditions of
the project.
The Site has largely met the required stream, vegetation, and hydrology success criteria for MY6 and is
on track to meet final MY7 performance standards. All restored and enhancement I streams are
geomorphically stable and functioning as designed. Bankfull and geomorphically significant event
criteria was met in MY2 with additional events recorded in MY6 including geomorphically significant
events for Vile Reach 2 on 3/23/2022 and 9/5/2022 and UT1 Reach 2 on 7/6/2022, 7/17/2022, and
8/9/2022. Fourteen of seventeen permanent vegetation plots and both transect plots met criteria. All
eight bog plots met appropriate percent cover. All ten gages in the wetland re-establishment, wetland
rehabilitation, and bog areas met or exceeded hydrology success criteria. Adaptive Management Plan
(AMP) tasks completed in MY5 are functioning as intended and MY6 supplemental planting appears
successful and will be closely monitored in MY7. Additional supplemental planting will occur before the
onset of the 2023 growing season in low stem density areas on the Site along sections of UT1 and UT2.
The MY6 Visual assessments revealed minor areas of concern including pockets of invasive plant species
and areas of low stem growth. The UT1 easement encroachment was addressed in January 2023 and all
other action items associated with the 2022 DMS easement inspection will be addressed in MY7. These
areas will continue to be monitored and adaptive management will be performed as needed.

Monitoring Year 6 Annual Report - FINAL

Section 1: PROJECT OVERVIEW
The Site is located approximately one mile east of the Town of Sparta in eastern Alleg hany 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 ranges 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 gains are limited to the Vile Creek project area, other benefits are anticipated to create more
widespread impacts including pollutant removal, reduced sediment loading, and improved aquatic and
terrestrial habitat. Expected enhancements to water quality and ecological processes are outlined below
as project goals and objectives. These intentions were established with careful consideration of targets
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:

1.2 Monitoring Year 6 Data Assessment
Annual monitoring and quarterly Site visits were conducted during MY6 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
MY6 is a reduced monitoring year that does not require morphological surveys therefore the stream
assessment was not performed this year. Visual Assessments revealed that project streams are
functioning as designed. Refer to Appendix 2 for visual assessment tables, Current Conditions Plan View
(CCPV) Figures 3.0-3.2, and reference photographs.
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.
The success criteria for bankfull and geomorphically significant events has been met on all monitored
reaches with at least five bankfull events occurring in separate years documented on UT1 Reach 2 and at
least four bankfull events occurring in separate years documented on Vile Creek. Two geomorphically

Monitoring Year 6 Annual Report FINAL 1-2

significant events were recorded in MY6 including Vile Creek Reach 2 on 3/23/2022 and 9/5/2022 and
on UT1 Reach 2 on 7/6/2022, 7/17/2022, and 8/9/2022. No bankfull events were recorded in MY6. Crest
gage (CG) 1 and CG2 probes experienced freezing temperatures and recorded incorrect water level data
during these times. Bankfull or geomorphically significant events recorded during freezing temperatures
were disregarded if they were not associated with rainfall events. Refer to Appendix 5 for hydrology
summary data and plots.
1.2.3 Vegetative Assessment
A total of 25 vegetation monitoring plots were installed during baseline monitoring throughout the
project easement to measure the survival of the planted trees, shrubs, and herbaceous vegetation.
Seventeen of the plots were established to evaluate woody species composition, density, and survival
rates, while 8 of the plots were established to evaluate percent coverage of herbaceous species of bog
areas. The size of individual quadrants is 100 square meters (10m x 10m or 5m x 20m) for woody tree
and shrub species and 20 square meters (5m x 4m) for herbaceous vegetation bog plots. In MY5 two
transect vegetation plots were added to evaluate a supplemental planting area from March 2021.
Transect vegetation monitoring plot assessments will document number of planted stems and species
using a circular or 100 square meters/rectangular plot.
Tree and shrub assessments are conducted following the 2006 Carolina Vegetation Survey (CVS) Level 2
Protocol for Recording Vegetation. The final planted stem vegetative success criterion for the Site is the
survival of 210 planted stems per acre in the planted riparian and wetland corridor at the end of the
required monitoring period (MY7). The interim measure of vegetative success for the Site is the survival
of at least 320 planted stems per acre at the end of the third monitoring year (MY3) and at least 260
stems per acre at the end of the fifth monitoring year (MY5). In addition, planted trees must average 8
feet in height in each plot at the end of the seventh year of monitoring according to the 2021 Vile Creek
Mitigation Site Adaptive Management Plan. Vegetation plots one and two contain only shrub species;
therefore, shrub stem density success criteria of 160 surviving plants per acre at the end of year 3, 130
at the end of year 5, and 105 at the end of year 7 is used for these plots. There are no height criteria for
shrubs. The bog plots are assessed by visually estimating the percent herbaceous coverage within each
plot and must have at least 80% coverage success criteria.
MY6 is typically a reduced monitoring year that does not require vegetation plot monitoring, but the
survey was completed in August 2022 as described in the 2021 Adaptive Management Plan (AMP). The
MY6 permanent plot vegetation monitoring resulted in an average planted stem density of 402 stems
per acre for woody tree species and 284 stems per acre for shrubs species, both of which exceed the
final requirement of 210 stems per acre for tree species and 105 stems per acre required for shrub
species and are on target to meet the requirements for MY7. In addition, 14 of the 17 plots individually
met the success criteria with a stem density ranging from 121 to 567 stems per acre for tree species and
243 to 324 for shrub species. Vegetation plots (VP) five, nine, and fourteen did not meet stem density
requirements at 202, 162, and 121 stems per acre respectively. Two of fifteen tree plots are meeting or
exceeding MY7 average height requirements and average height across all woody plots (excluding shrub
plots) is below the MY7 requirement at 5.6 feet. All herbaceous bog plots are exceeding success criteria
with each reaching a minimum of 98% herbaceous cover. Both transect vegetation plots added to the
supplemental planting area in March 2021 exceed the final requirement with an average of 445 stems
per acre and are on target to meet the tree density requirements for MY7.
The Gray's Lily (Lilium grayi) GPS locations are included in the CCPV. Photographs from the last known
occurrence on the Site are included in Appendix 2. The two locations will be surveyed in during peak
blooming season in June and July of MY7. Refer to Appendix 2 for vegetation plot photographs and
Appendix 3 for vegetation data tables.

Monitoring Year 6 Annual Report FINAL 1-3

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. The original site Barotroll failed on 9/22/2021 and was replaced on
2/11/2022. Groundwater monitoring gages are downloaded on a quarterly basis and maintained as
needed. Calibration is completed by manually measuring water levels on all gages to confirm the
downloaded data. Under typical precipitation conditions, the final performance success criteria for
groundwater hydrology includes 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
wetland re-establishment and wetland rehabilitation areas and 20 consecutive days (12%) of the defined
169-day growing season (April 26 — October 11) for bog areas.
All 10 GWGs met MY6 success criteria with an overall hydroperiod ranging from 14% to 100% of the
growing season. The failed barotroll resulted in minor dormant season data loss. Manual measurements
of GWG water levels were recorded quarterly during MY6. Instances of uncharacteristically low water
levels on several hydrographs in May 2022 signify readings directly after a well was pumped to remove
unwanted bentonite from the bottom of the well and does not reflect true hydrologic conditions.
Rainfall data was collected from the NIC-AG-1-Sparta 3.5 SSW(NICCRONIOS) rain gage. Average rainfall
was recorded in March, April, and June. Higher than average rainfall occurred in February, May, July,
and August while below average rainfall occurred in January and July. Refer to the CCPV Maps in
Appendix 2 for groundwater gage locations and Appendix 5 for groundwater hydrographs and rainfall
summary plots.
1.2.5 Areas of Concern
The UT1 Reach 1 (Station 205+10-205+60) natural stream realignment that occurred in MY4
(approximately 21-feet) appears to be stable and will remain closely monitored.
Stream repairs addressed in the IRT approved MY5 Adaptive Management Plan (AMP) and completed in
September 2021 are stable and functioning as designed as shown in the Repair Photo Log in Appendix 2.
Supplemental planting occurred along Vile Creek Reaches 1 and 3 in April 2022 in accordance with the
MY5 AMP. Approximately 200 one -gallon and 3-gallon container plants were planted in four areas
totaling one acre. Some planted species were not in the approved Final Mitigation Plain but were
subsequently approved in the MY5 AMP (Wildlands 2016, 2021). These include boxelder (Acer negundo),
red oak (Quercus rubra), white oak (Quercus alba), and black gum (Nyssa sylvatica). Additionally, soil
amendments comprised of humic acid, biochar, dried molasses, slow -release fertilizer (2-4-3), rock
phosphate, and azomite were added to the base of each planted tree in June 2022 to improve moisture -
holding capacity, organic matter, and nutrient availability. These areas will remain closely monitored in
M Y7.
Additional supplemental planting will occur before the onset of the 2023 growing season in low stem
density areas on Site (approximately 1 acre) including an area along the left bank of UT1 and upstream
sections of UT2. The areas will be replanted with one, three, and/or five -gallon containerized trees.
Species will include those approved in the Vile Creek Mitigation Site Final Mitigation Plan and 2021 Vile
Creek Mitigation Site Adaptive Management Plan (Wildlands 2016, 2021). The planted species, sizes,
wetland indicator status, and quantities will be documented in the MY7 monitoring report. Refer to
Appendix 2 for supplemental planting locations and low stem density acreages.
WVile Creek Mitigation Site
Monitoring Year 6 Annual Report FINAL 1-4

Aggradation on UT1b (Station 251+02 — 251+64 (62')) and UT1c (Station 271+66 — 272+81 (115')),
continues to result in sheet flow onto the floodplain rather than maintaining flow within a single thread
channel. Wetland vegetation and hydrology was observed in these areas in MY6. At MY7 Wildlands will
verify the jurisdictional limits of UT1C and UT1B and include it in the monitoring report. Wildlands will
coordinate with IRT and DIMS prior to closeout to determine the mitigation approach, credit ratios, and
acreage of these features so the appropriate amount of wetland credit can be added to the site and the
necessary amount of stream credit can be removed. Refer to Appendix 2 for photographs and Appendix
5 for hydrology data.
Small pockets of invasive species including multiflora rose (Rosa multiflora) and Chinese bittersweet
(Celastrus orbiculatus) exist on <1% of the Site and are not impacting survival rates of planted stems.
Targeted spray treatment conducted in June 2022 along most restoration and enhancement reaches
reduced the presence of multiflora rose within the easement. Additional treatments will continue as
needed to help manage and eliminate remaining invasive species populations.
One easement encroachment was observed along the upstream section of UT1. Wildlands installed
additional signage and horse tape in January 2023 to clearly mark the boundary of the easement along
UT1. The area will be replanted along with scheduled UT1 supplemental planting before the onset of the
2023 growing season. Wildlands was informed of additional issues after a DMS easement inspection of
the Site on October 12, 2022. In reference to listed action items, monument caps with missing markings
will be stamped in MY7 by the contracted surveyor per agency requirements. Wildlands will repair
damaged fencing along UT1 Reach 2 and the damaged sign along UT1c. There was no vegetation trimming
observed around the mobile deer stand in the easement along Vile Creek Reach 2 and no damage due to
easement access. Wildlands investigated potential encroachment along the left bank of UT2 in January
2023. Pasture mowing appeared to be up to the easement line and no encroachment was observed. The
landowner was notified, and additional signage will be added in MY7. The mobile deer stand was located
outside of the easement. Refer to Appendix 2 for encroachment details and Appendix 6 for email
correspondence.
Isolated stream areas of concern are noted on the CCPV. These areas are not negatively impacting
overall stream function or stability, but they will be monitored in MY7 for signs of instability. Refer to
Appendix 2 for vegetation and stream condition assessment tables and the CCPV maps.
1.3 Monitoring Year 6 Summary
The Site has largely met the required stream, vegetation, and hydrology success criteria for MY6 and is
on track to meet final MY7 performance standards. All restored and enhancement I streams are
geomorphically stable and functioning as designed. Bankfull and geomorphically significant event
criteria was met in MY2 with additional events recorded in MY6 including geomorphically significant
events for Vile Reach 2 on 3/23/2022 and 9/5/2022 and UT1 Reach 2 on 7/6/2022, 7/17/2022, and
8/9/2022. Fourteen of seventeen permanent vegetation plots and both transect plots met criteria. All
eight bog plots met appropriate percent cover. All ten gages in the wetland re-establishment, wetland
rehabilitation, and bog areas met or exceeded hydrology success criteria. Adaptive Management Plan
(AMP) tasks completed in MY5 are functioning as intended and MY6 supplemental planting appears
successful and will be closely monitored in MY7. Additional supplemental planting will occur before the
2023 growing season in low stem density areas on the Site along sections of UT1 and UT2. The MY6
Visual assessments revealed minor areas of concern including pockets of invasive plant species and

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 subject project site is an environmental restoration site of
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.
