1.0 Introduction
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.
On -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. Vile Creek flows into Little River near the
downstream project boundary. The land adjacent to the project streams and wetlands is primarily
maintained cattle pasture and forest. 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.
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 final Baseline
Monitoring Document was completed in April 2017. The Site is currently in Monitoring Year 5 (MY5).
Overall, the Site is geomorphically stable, and riparian and wetland vegetation are performing well.
Performance criteria for stream hydrology has been met, and all wetland groundwater gauges met their
success criteria during MY4. However, isolated stream and vegetation problems areas do exist on -site.
One of these areas consisting of erosion on the outside meander bend of Vile Creek Reach 2 was
observed during MY1 and discussed during an IRT site walk conducted on July 18, 2017. The remainder
of the stream problem areas have occurred and been documented in subsequent monitoring year
reports (MY2 — MY4) including damage that occurred during a hurricane and a tropical storm in the fall
of 2018 (MY2). In addition, areas of concern related to vegetation performance have been documented.
Three supplemental plantings have already occurred. The first was completed to correct the planting of
trees in shrub zones, which were intended to minimize shade on the bog areas. Trees were removed
from the shrub zones and shrubs were planted to replace them during the winter of 2017. The second
supplemental planting consisted of 300 1-gallon trees and was completed in the spring of 2020 on the
right bank UT1 R2 starting at UT1C and continuing down to Vile Creek Reach 2. Elderberry live stakes
were also planted along the top of bank of UT1 to further shade out the stream. All of the 1-gallon
plantings were considered unsuccessful because the deer population located on -site grazed the newly
planted stems causing a mortality rate of greater than 50% of the supplementally planted stems. A third
supplemental planting was the performed to replace the grazed container plants during the winter of
2021. This planting consisted of 854 1-gallon and 3-gallon containerized plants in the same area along
UT1 R2 and tree cones were used to prevent deer browse. When these new trees were planted, a
pepper pellet was also placed beneath the root ball of many of the trees which gives the leaves and
branches a bad taste, also to discourages deer browse.
An IRT site visit was conducted on June 24, 2021. During this site visit, potential repairs were discussed
with the members of the IRT. A determination was made to move forward with on -site repairs including
bank stabilization of four areas, repairs to certain failing structures, reconstruction of a failing angled -log
riffle, and multiple small areas of replanting. These repairs are discussed in Section 3.0 of this
document.

2.0 Monitoring Years 3 and 4 Assessments
Annual monitoring and quarterly Site visits have been conducted since project completion 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). Stream and
vegetative monitoring features and locations are shown in Figures 1 to 3 in Appendix 1.
2.1 Performance Criteria
2.1.1 Vegetation
The vegetative success criteria for the Site consists of species survival in three designated zones (trees,
shrubs, and bogs) along the open, planted riparian corridor. The vegetative success criteria for tree
species will be the final survival of 210 planted stems per acre at the end of the required seventh
monitoring period, as well as an interim criteria of the survival of at least 320 planted stems per acre at
the end of MY3 and at least 260 stems per acre at the end of MY5. Planted tree height must average 6
feet in height by MY5 and 8 feet in height at the end of the MY7. The vegetative success criteria for
shrub species will be the final survival of 105 planted stems per acre at the end of MY7, of at least 160
planted stems per acre at the end of MY3, and at least 130 stems per acre at the end of MY5. There is
no height requirement for shrub species. The vegetative success criterium for bog areas is at least 80%
herbaceous cover.
2.1.2 Stream
Stream channels should maintain a stable pattern and profile considering the hydrologic and sediment
inputs to the system, the landscape setting, and the watershed conditions. Bank height ratios should
stay below 1.2. Visual assessments should indicate a progression towards stability. Entrenchment ratios
should be >1.4 for restored B channels and >_2.2 for C/E channels. Cross -sections should show little
change in bankfull area and width -to -depth ratio.
2.2 MY3 and MY4 Assessment Results
2.2.1 Vegetation
MY4 (2020) was a reduced monitoring year that does not require detailed vegetation inventory and
analysis; therefore, no vegetation plot monitoring was performed in 2020. Visual assessments were
conducted in MY4 and indicated isolated areas of low stem density and height. Detailed vegetative
inventories were completed in MY3 (September 2019). This resulted in an average planted stem density
of 445 stems per acre for woody tree species, 284 stems per acre for shrubs species, and approximately
99% herbaceous cover in bog areas, which exceed the interim requirement of 320 stems per acre for
trees and the 160 required for shrub species at MY3, as well as the final 80 percent cover for bog areas.
Of the 25 vegetative plots monitored, twelve of the fifteen plots designated for monitoring tree species,
both of the plots designated for monitoring shrub species, and all eight plots designated for monitoring
herbaceous cover in bog areas, individually met the success criteria with a stem density ranging from
364 to 728 stems per acre for trees and 162 to 405 stems per acre for shrubs and a vegetative cover of
95 — 100% for bog areas. Vegetation plots five, nine, and fourteen did not meet stem density
requirements. See Appendix 2 (Tables 2 and 3a-b) for the MY3 vegetation plot monitoring results.
2.2.2 Stream
MY4 was a reduced monitoring year that does not require full morphological surveys; therefore, no
cross -sectional surveys were performed in 2020; however, pebble counts were conducted and found no
significant change in stream bed material throughout the site. Morphological cross -sectional surveys
conducted in MY3 (April 2019) indicated, in general, that streams within the Site appeared stable with
some areas exhibiting minor bank scour. In general, site streams showed little change in the bankfull

area, maximum depth ratio, and width -to -depth ratio, and fell within the parameters defined for
channels of the appropriate stream type (Rosgen, 1994 & 1996).
During MY3, cross -sectional survey results showed a bank height ratio greater than 1.2 for cross-section
(XS) 2 and XS7. XS7 had degraded during MY1, but remained stable in subsequent years. Cross section
two began to degrade in MY1 and continued to degrade through MY3. However, this cross-section is
located in between two logs in a log riffle and is expected to see some deepening of a scour pool in this
location of the riffle.
2.3 Areas of Concern
2.3.1 Vegetation
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.
Although their presence is not impacting survival rates of planted stems at this time, these areas will
likely continue to warrant additional treatment to prevent any advancement within the conservation
easement and future impacts to the Site.
During MY4 areas of low stem density and height were documented on -site and amounted to 18.2% of
the planted conservation easement. These areas included: 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 (this
area was replanted a second time during the winter of 2021), and along the left floodplain of UT2 just
below the BMP. During the 2021 IRT site visit, low tree density was also observed along both banks of Vile
Creek Reach 1 and portions of the left bank of Vile Creek Reach 3. See figures in Appendix 1 for locations
of low tree density discussed during the 2021 IRT site visit.
2.3.2 Stream
The site has been assessed quarterly since the completion of construction as discussed in Section 2 above.
The following areas are experiencing localized bank instability to varying degrees: Vile Creek Reach 1
station 103+90-104+20 (30 LF), Vile Creek Reach 2 stations 118+50-118+80 (30 LF), 120+50-121+00 (50
LF), 121+00 to 121+25 (25 LF), and 122+20-123+00 (80 LF), UT1 Reach 1 station 206+40-206+60 (20 LF),
UT2 stations 305+00-305+50 (50 LF), 306+30-306+70 (40 LF), and 310+00-310+15 (15 LF). Aggradation
along enhancement II reaches UT1b and UT1c has resulted in the 51 LF and a 115 LF loss of the single -
thread channels, respectively. The stormwater best management practice (BMP) at the top of UT2 has
formed a headcut at the inlet flowing into the BMP. An area of instability along UT1 Reach 1 (Station
205+10-205+60) that was previously mentioned in the MY3 report, naturally realigned itself (21 LF) in
MY4; thereby, abandoning an existing meander bend and creating an ox bow. The newly created channel
appears to be stable but resulted in a loss of 14 LF of stream. Stream structures currently failing include:
rock sill UT1 Reach 2 at station 220+98, log sill Vile Creek Reach 1 station 104+10, j-hook Vile Creek Reach
2 at station 118+80, rock sill Vile Creek Reach 2 at station 123+00. A constructed angled log riffle has
down -cut and has failing log sills on Vile Creek Reach 2 at station 122+25.

3.0 Corrective Measures for Implementation
3.1 Site Assessment
As previously mentioned in Section 1.0, an IRT site visit was conducted on June 24, 2021. During this
visit, areas within the project's conservation easement were discussed for stream repair and additional
supplemental planting. Key points discussed during this visit are outlined below and resulted in the
proposed corrective measures for implementation. Supplemental planting and stream repair measures
are discussed in further detailed in Sections 3.2 and 3.3.
• Wildlands to repair the lower end of Vile Creek Reach 2 including bank repairs and
repair/replace log sills and a boulder sill.
• Wildlands to install container sized plants and live stakes within the bare spots along Vile Creek
Reach 1 to provide shade for cold water stream habitat.
• Wildlands will not remove and/or repair aggradation areas along UT1b and UT1c.
• Wildlands will continue to treat invasives on the project site including multiflora rose, Chinese
privet, and Japanese barberry, as needed.
• Since cattails are not negatively affecting the performance of the stormwater BMP at the top of
UT2, Wildlands is not planning to treat them at this time.
• Wildlands will add rock to stabilize the headcut at the inlet to the stormwater BMP.
• Wildlands to stabilize the erosion and replant the overflow channel on Vile Creek Reach 3.
• Wildlands will perform supplemental planting along the left bank of Vile Creek Reach 3 during
the next dormant season.
3.2 Replanting
3.2.1 Areas to Be Replanted
A fourth replanting will be completed on a portion of the site during the upcoming dormant season
(winter 2022). This planting will focus on the areas discussed at the recent IRT site visit and will include:
Vile Creek Reach 1
• Replant with containerized trees within the riparian planting zone (extending 15 feet from top of
bank) along both banks of the stream along the entire reach.
• Install additional live stakes to streambanks to help with shading the stream.
Vile Creek Reach 3
• Replant with containerized trees along the left bank of the stream from approximately station
125+00 to 126+00 and 127+00 to 128+25.
• Install additional live stakes on left bank of the secondary high -flow channel on Vile Creek Reach
3 from approximately station 124+80 to 125+60.
See Section 3.2.2 and 3.2.3 below for the list of the proposed planted tree and live stake species.
3.2.2 Container Plantings
Approximately 200 containerized trees will be replanted during the next dormant season (winter 2022)
along both banks of Vile Creek Reach 1 and a small area on the left bank of Vile Creek Reach 3 as shown
on the figures in Appendix 1. The total area of the replanting will be approximately 1 acre. The trees
will be a combination of one -gallon and three -gallon containers, depending on the availability of stock.
The species for replanting were selected based on recent experience with planting similar sites and are
listed below. Many of these species were not in the approved Final Mitigation Plan (Wildlands, 2016)
and these species are noted below with an asterisk. The proposed trees to plant include:
W Vile Creek Mitigation Site
Adaptive Management Plan
DMS ID#: 96582
August 2021
Page 3-1

• Box elder (Acer negundo)* - FAC — 10%
• American sycamore (Platanus occidentalis) — FACW — 15%
• River birch (Betula nigra) — FACW — 15%
• Persimmon (Diospyros virginiana) — FAC— 15%
• Red oak (Quercus rubra)* - FACU — 15%
• White oak (Quercus alba)* - FACU — 15%
• Black gum (Nyssa sylvatica)* - FAC — 15%
Potential alternate species will be used if any of the above are not available and include:
• Black cherry (Prunus serotina)* - FACU
• Tag alder (Alnus serrulata) - OBL
• Yellow buckeye (Aesculus flava)* - FACU
See Appendix 3 for the approved planting list from the Final Mitigation Plan (Wildlands, 2019).
3.2.3 Live Stakes
Live stake plantings will also be conducted during the winter of 2022. The additional live stakes will be
placed primarily in areas where repairs are being done. Live stakes will consist of a mix of black willow
(Salix nigra), silky willow (Salix sericea), and silky dogwood (Cornus amomum). Both silky willow and silky
dogwood were included in the approved Final Mitigation Plan (Wildlands, 2019); however, black willow
was not. Wildlands believes that adding black willow as an additional species to the live stake planting
list will aid stream bank stabilization with their ability to become quickly established and will further
increase species diversity.
See Appendix 3 for the approved planting list from the Final Mitigation Plan (Wildlands, 2019).
3.2.4 Soil Amendments
Soil amendments will also be applied to the newly planted areas at a rate of approximately 3 ounces to
the base of each planted tree. Soil amendments will include humic acid, biochar, dried molasses, slow -
release fertilizer (2-4-3), rock phosphate, and azomite (a trace mineral supplement). Beyond boosting
macro- and micronutrients in the soil, the addition of these amendments will improve other soil
properties including cation exchange capacity, pH, and microbial communities. Expected improvements
include greater moisture -holding capacity, organic matter, and nutrient availability for plants.
3.3 Stream Repairs
3.3.1 Areas to be Repaired
The following areas will be repaired as described:
Vile Creek Reach 2
• Repair eroding right stream bank from station 118+50 to 118+80.
• Repair existing J-Hook at station 118+80.
• Repair eroding right stream bank from station 120+70 to 121+00.
• Repair eroding left stream bank from station 121+00 to 121+25.
• Repair eroding right stream banks from station 122+20-123+00.
• Rebuild log riffle from station 122+20 to 123+00.
• Repair rock sill at station 123+00.
Vile Creek Reach 3
• Repair eroding left bank of overflow channel from station 125+00 to 125+60 and replant with
bare roots.

Page 3-2

Pre -repair photos of the locations described above are included in Appendix 1. All completed repairs
listed above will be documented in the MY5 report. Most other areas of concern listed in Sections 2.3.2
are minor and will continue to be monitored by Wildlands and discussed in upcoming monitoring
reports for monitoring years 5 through 7. According to IRT members, the aggradation of UT1b and UT1c
may result in the change of credit type from stream to linear wetland. Wildlands will coordinate with
the IRT and DMS prior to closeout to determine the mitigation approach, credit ratios, and acreage of
these wetlands so that the appropriate amount of wetland credit can be added to the site and the
necessary amount of stream credit can be removed.
3.3.2 Description of Repairs
The repairs will be conducted with a small excavator during late summer or early fall of 2021. All of the
areas to be repaired are located on the lower half of Vile Creek Reach 2 and access will be limited to one
route in and out of that location. All of the bank repairs will consist of building geolifts to stabilize the
eroding areas. Live stakes will be installed during the winter of 2022 to add stability to the geolifts. The
log riffle to be repaired will be rebuilt to the original design elevation and all of the angled logs will be
replaced and keyed into the bank sufficiently to remain stable. The rock sill and j-hook will be repaired
by replacing the rocks that washed out and keying them into the bank sufficiently so that they remain
stable.
3.3.3 Permitting
Wildlands discussed permitting requirements with the U.S. Army Corps of Engineers (USACE) and the NC
Division of Water Resources (NCDWR). The project's 401 and 404 permits expired in 2017. However,
the USACE indicated that the work would be covered under a non -reporting NW3 and GC4132 because
these permits allow for maintenance work on previously authorized modifications, as outlined in
paragraph (a) of the NW3. Because the repair work is located within the project's previously permitted
stream restoration construction area and with proposed in -stream structures and bank stabilizations
consistent with the original restoration design, DWR considers the proposed work to be temporary
impacts not requiring written 401 approval. Therefore, for these repairs, no additional 401 or 404
notifications are required. The project repairs will comply with trout moratorium rules. Any other
necessary permits will be obtained. A land disturbance permit should not be necessary because less
than 1 acre will be disturbed.

4.0 Proposed Monitoring
4.1 Vegetative
Wildlands will continue to monitor Site vegetation as previously planned. If the monitoring requirements
are not met during MY7 in any of the planted areas, including ones with supplemental planting,
Wildlands proposes to add another year of vegetation monitoring for those areas. Vegetation
monitoring will continue until success criteria are met. We will include two transects in the
supplemental planting area that was recently planted in March of 2021 to monitor success for MY5, and
MY6, and MY7. Full vegetation monitoring at the site will be conducted in MY6. MY6 is a reduced
monitoring year and does not typically include vegetation monitoring.
4.2 Stream
Wildlands will continue to monitor the stream as previously planned. However, the portions of UT1C
and UT1B that are functioning as wetlands will be tracked in linear footage to determine if the aggraded
areas are increasing or decreasing in length. An additional photo point will be added on each of these
two reaches and on UT1 Reach 1 at station 205+10-205+60 where the stream realigned itself and
formed an oxbow where the channel used to be. In addition, a photo point will be added at each of the
seven stream repair areas. This data will be added to the MY5, MY6, and MY7 reports. If other areas of
concern begin to threaten the stability of the project, then remedial actions will be implemented and
documented for all future reports.

5.0 Conclusion
In summary, Wildlands proposes to repair damage that has occurred since construction was completed
in 2017 to the lower part of Vile Creek Reach 2 during the late summer of 2021. Additional replanting
will be done during the following dormant season (Winter 2022). Soil amendments will be placed
around each supplementally planted bare root to aid in growth and establishment. Stability of repair
areas and growth and health of supplementally planted areas will be reevaluated in the Monitoring Year
5 to 7 reports along with pictures of the addressed areas.

The reduction in wetland re-establishment acreage from design to as -built stages was mainly due to Vile Creek
Reaches 1 and 2 having wider top widths in the as -built survey than in the design wetland area calculations. Thus,
Vile Creek cut more into the wetland area in the as -built plans than it did in the design calculations, resulting in
lower as -built wetland acreage.
1 Creditable As -Built footage excludes conse vation easement breaks and a section along UT3 that exists outside of conservation easement.
'As -Built credits (SMUs) have been adjusted where the easement is restricted and the full buffer width and/or bankfull width is not fully contained within the conservation easement. The reductions are greater in the as -built compared to
the mitigation plan. The as -built credit reductions follows the updated 2016 USACE Wilmington District Stream and Wetland Compensatory Mitigation update.
'Stream mitigation credits and stationg noted above are based on the as -built stream centerline.

MY2 - MY7 Bank Height Ratio was calculated based on the As -built (MVO) cross -sectional area as de cribed in the Standard Measurement of the BHR Monitoring Parameter document provided by the NCIRT and NCDMS (9/2018). The remainder of the cross-section dimension parameters were calculated based on
the current year's low bank height.
ER in MY3 is based on the width of the cross-section, in lieu of assuming the width across the floodp ain as was done in previous monitoring years.
Prior to MY2, bankfull dimensions were calculated using a fixed bankfull elevation.
