Wildlands Yadkin Valley Umbrella Mitigation Bank – Critcher Brothers Mitigation Site
Fifth Credit Release (Monitoring Year 3 Completion)
Dear Mr. Kichefski:
This correspondence is in reference to the Critcher Brothers Mitigation Site, part of the Wildlands Yadkin Valley
Umbrella Mitigation Bank. The 72.46-acre site is in the Upper Yadkin Watershed of the Upper Pee Dee River
Basin (03040101) and is located 7 miles east of Wilkesboro in southeast Wilkes County, North Carolina. The
purpose of this letter is to request the fifth release of credits (Year 3 Monitoring Complete) for this mitigation
site.
Monitoring year 3 (MY3) site assessments were conducted between January and December 2023. Overall, the
Site has met the required stream, vegetation, and hydrology success criteria for MY3. The project streams are in
good condition and functioning as intended, with only minor instances of scour or aggradation identified. At
least one bankfull event has been documented on all the required project reaches since the completion of
construction. Vegetation assessments indicated an average planted stem density of 497 stems per acre and
overall, the Site has met the MY3 requirement of 320 stems per acre. While about 96% of the Site is free of
invasive species, a few small populations of invasive plant species were identified in 2023. Wildlands will
continue monitor all areas of concern and document repairs and management activities in the MY4 report.
Pursuant to the Umbrella Mitigation Banking Instrument and the site-specific Critcher Brothers Final Mitigation
Plan, successful completion of monitoring year 3 activities and demonstration that interim performance
standards are being met for all parcels within the bank grants ten percent (10%) of the mitigation site’s total
stream restoration and enhancement credits be available for sale. We are requesting 2,010.21 stream mitigation
units (SMUs) be released. With this release, 60% of the total stream restoration and enhancement credits and
100% of the total stream preservation credits will have been released.
Please contact us at 704-332-7754 if you have any questions.
Thank you,

Monitoring Year 3 Annual Report - FINAL i
EXECUTIVE SUMMARY
Wildlands Engineering, Inc. (Wildlands) implemented the Critcher Brothers Mitigation Site (Site) as part
of the Yadkin Valley Umbrella Mitigation Bank. The Site is located in Wilkes County, North Carolina
within the Yadkin River Basin Hydrologic Unit Code (HUC) 03040101. The Site was selected to provide
stream mitigation credits to compensate for permitted impacts to Waters of the United States within
the Yadkin River Basin 03040101 (Yadkin 01) service area. The project includes the restoration,
enhancement, and preservation of 27,938 linear feet (LF) of stream on South Fork Fishing Creek, West
Fork Fishing Creek, and 22 tributaries. At the time of As-Built, the Site was determined to generate
20,578.400 cool stream mitigation units (SMUs). With additional enhancement II work completed on
Magnolia Tributary at the IRT’s request, the net credits have increased by 13.333 SMU to a total of
20,591.733 SMU. The Site is protected by a 72-acre conservation easement spanning three parcels.
Cattle farming, timber harvesting and other agricultural activity in the Yadkin River Valley has negatively
impacted stream function throughout the basin. Major stream stressors to the Site included
concentrated agricultural runoff inputs, degraded instream habitat, active stream incision, bank erosion
and failure, and a lack of stabilizing streamside vegetation and bedform diversity. The effects of these
stressors resulted in degraded water quality and habitat throughout the Site compared to reference
conditions. The project approach focused on evaluating the existing functional condition, potential for
recovery, and need for intervention.
The project goals defined in the Mitigation Plan (Wildlands, 2019) were established with careful
consideration of 2009 Upper Yadkin River Basin Restoration Priorities (RBRP) goals and objectives to
address stressors identified in the watershed. The established project goals included:
 Reducing pollutant inputs to streams including fecal coliform, nitrogen, and phosphorus;
 Reducing inputs of sediment into streams from eroding stream banks;
 Returning networks of streams to a stable form that is capable of supporting hydrologic,
biologic, and water quality functions;
 Raising local groundwater elevations and allow for more frequent overbank flows to reduce
shear stress on channels during larger flow events;
 Improving aquatic habitat in project streams;
 Creating and improving riparian habitats to provide a canopy to shade streams and reduce
thermal loadings, to create a source of woody inputs for streams, to reduce flood flow velocities
on the floodplain, and to improve long-term lateral stability of streams; and
 Ensuring that development and agricultural uses that would damage the site or reduce the
benefits of project are prevented.

The Site construction and as-built surveys were completed between April 2020 and February 2021.
Planting and baseline vegetation data collection occurred during February 2021. Monitoring Year (MY) 3
assessments and site visits were completed between January 2023 and December 2023 to assess the
conditions of the project.
Overall, the Site has met the required stream, vegetation, and hydrology success criteria for MY3. The
overall average planted stem density for the Site is 497 stems per acre and is on track to meet the MY5
requirement of 260 stems per acre. Geomorphic surveys indicate that cross-section bankfull dimensions
closely match the baseline monitoring with some minor adjustments, and streams are functioning as
intended. At least one bankfull event was documented on all required project reaches since the
completion of construction and 15 of 19 reaches have documented 2 or more bankfull events in 3
separate years. The MY3 visual assessment identified a few areas of concern including small populations
of invasive plant species or minor instances of scour, erosion, or aggradation. Adaptive management will

be implemented as necessary throughout the seven-year monitoring period to benefit the ecological
health of the Site.

Critcher Brothers Mitigation Site
Monitoring Year 3 Annual Report - DRAFT 1-1
Section 1: PROJECT GOALS, BACKGROUND, AND ATTRIBUTES
The Yadkin Valley Umbrella Mitigation Bank (Bank) sites are located in Wilkes, Watauga, and Surry
Counties. The site described in this Annual Monitoring Report is the Critcher Brothers Mitigation Site
(Site) which is located approximately 7 miles east of the Town of Wilkesboro in Wilkes County in the
Yadkin River Basin 14-digit hydrologic unit code (HUC) 03040101060060, and the North Carolina Division
of Water Resources (NCDWR) Sub-basin 03-07-01 (Figure 1). The Site is protected by a 72-acre
conservation easement spanning three parcels.
The main stem of the project, South Fork (SF) Fishing Creek, flows generally northwest through the
center of the Site and drains 3,942 acres of surrounding land. SF Fishing Creek has a gently sloped
alluvial valley that ranges from unconfined to moderately confined. Critcher Tributary, Antioch
Tributary, Chicken Tributary 1, Robin Hill Tributary, and Oak Tributary each have steep, confined valleys
that widen at the downstream end as the streams enter the floodplain of SF Fishing Creek. West Fork
(WF) Fishing Creek has a gently sloped alluvial valley with an unconfined floodplain. Magnolia Tributary,
Ironwood Tributary, Shew Ridge Tributary, and Timber Tributary have steep confined valleys that widen
as they enter the flatter receiving floodplain of WF Fishing Creek. WF Fishing Creek joins SF Fishing Creek
towards the downstream limits of the Site. Located within the Inner Piedmont lithotectonic belt of the
Piedmont physiographic province, the Site topography and relief are typical for the region (NCGS, 1985).
Generally, the project watershed is dominated by agricultural and forested land.
Prior to construction activities, the Site was used for livestock grazing, crop production, and maintained
as managed herbaceous cover or forested lands. Vegetation in project reaches with partially wooded
riparian buffers was largely overwhelmed by invasive species and cattle impacts. Cattle farming and lack
of well-established riparian buffers, associated with current and historical agricultural use, contributed
to major stream impairments across the Site including bank erosion, stream incision, excess fine
sediment and nutrient loading, and poor in-stream habitat. Pre-construction conditions are outlined in
Table 4 of Appendix 1.
The final mitigation plan was submitted and accepted by the North Carolina Interagency Review Team
(NC IRT) in July 2019. Construction activities were completed in February 2021 by Wildlands
Construction and Land Mechanic Designs. Kee Mapping and Surveying PA completed the as-built survey
in February 2021. Planting was completed in February 2021 by Bruton Natural Systems, Inc. Refer to
Appendix 1 for detailed project activity, history, contact information, and watershed/site background
information.
Directions and a map of the Site are provided in Figure 1, and project components are illustrated for the
Site in Figure 2.
1.1 Project Goals and Objectives
The Site is providing numerous ecological benefits within the Yadkin River Basin. The project goals were
established with careful consideration to address stressors that were identified in the RBRP (EEP, 2009).
Improvements to water quality and ecological processes are outlined below as project goals and
objectives.

Ensure that development and agricultural
uses that would damage the Site or
reduce the benefits of project are
prevented.

Establish conservation easements on the Site.
1.2 Monitoring Year 3 Data Assessment
Annual monitoring for MY3 was conducted between January and December 2023 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 Critcher Brothers Mitigation Plan (Wildlands, 2019).

Critcher Brothers Mitigation Site
Monitoring Year 3 Annual Report - DRAFT 1-3
1.2.1 Vegetation Assessment
Vegetation plot monitoring is being conducted in post-construction monitoring years 1, 2, 3, 5, and 7.
Permanent plots are monitored in accordance with the guidelines and procedures developed by the
Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008) and the 2016 USACE Stream and
Wetland Mitigation Guidance to assess the vegetation success. A total of 15 permanent vegetation plots
were established within the easement. All permanent plots were established as either a 10-meter by 10-
meter square plot or 5-meter by 20-meter rectangular plot. In addition, 10 mobile vegetation plots were
arbitrarily established in MY3 throughout the planted area to evaluate the random vegetation
performance for the Site. Mobile plots will be re-established at varying locations in monitoring years 3,
5, and 7. Mobile vegetation plot assessments will document stem count, species, and height using a
circular or 100-meter square/rectangular plot.
The final vegetative performance standard will be the survival of 210 planted stems per acre in the
planted riparian areas at the end of the required seven-year monitoring period. The interim measure of
vegetative success for the Site will be 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. It should be noted that no single planted or
volunteer species shall comprise more than 50% of the total stem density within any plot at year three,
five, or seven. In NC mountain counties, planted trees must average 6 feet in height in each plot at the
end of MY5 and 8 feet in height at MY7. For both permanent and random plots, all woody stems,
including exotic and invasive species, should be counted. Supplemental plantings and volunteer plants
must be present for at least two growing seasons before counting toward performance standards for
monitoring years five and seven. Invasive species will not count toward success of performance
standards.
The MY3 vegetation survey was completed in July 2023. The average planted stem density for the Site is
497 stems per acre. In MY3, 23 out of the 25 (92%) vegetation plots are on track to individually meet the
interim MY3 requirement of 320 planted stems per acre. Stem densities in monitored vegetation plots
ranged from 162 to 1,174 stems per acre. Refer to section 1.2.2 for further discussion about vegetation
plots that are not meeting the MY3 density requirements.
In MY3, the survival rate of monitored stems was approximately 95% in the permanent vegetation plots,
with red oak (Quercus rubra) and black cherry (Prunus serotina) exhibiting the highest mortality rates
among planted stems. Stems in permanent vegetation plots are thriving, with 91% of stems scoring a
vigor of 3 or greater indicating robust overall health and minimal stem damage. Approximately 2% of
stems scored a vigor of 2 or 1. This low vigor rating is likely due to suffocation from dense herbaceous
vegetation, poor soil conditions, storm damage, or other unknown factors.
Per IRT request, an additional shaded vegetation transect (SVT) was established in the shaded planting
area of SF Fishing Creek Reach 9. The MY3 assessment revealed that both planted and volunteer stems
are thriving and resulted in a density of 1,740 stems per acre in this area. This shaded vegetation
transect is not held to the vegetative performance standards for the Site. Refer to Appendix 2 for
vegetation plot photographs and Appendix 3 for vegetation data tables.
1.2.2 Vegetation Areas of Concern and Management Activity
Invasive Species
MY3 visual assessments indicate that over 96% of the Site is free of invasive species. Invasives were
generally seen growing in existing wooded buffers on Site and total 3.0 acres or approximately 4% of the
total easement acreage. Several patches of Chinese privet (Ligustrum sinense) were documented on
Robin Hill Tributary Reach 1, West Fork Fishing Reaches 1, 4 and 5 and SFFC Reaches 9 and 10.
Occurrences of Japanese honeysuckle (Lonicera japonica) were observed on Timber Trib Reach 2. Kudzu

Critcher Brothers Mitigation Site
Monitoring Year 3 Annual Report - DRAFT 1-4
(Pueraria montana) runners were identified along SFFC Reaches 2 and 3 but were swiftly treated upon
observation in July 2023. Targeted invasive species treatments including mechanical removal and
herbicide applications were completed by a contractor in October and November 2023. Wildlands will
continue to treat mapped invasive species in MY4. While the amount of Marsh dewflower (Murdannia
keisak) on Site was greatly reduced in MY3, smaller streams such as Robin Hill Trib A and Antioch Trib A
Reach 2 are still affected by in-stream vegetation and associated aggradation. These areas were treated
with herbicide applications in July 2023, and are likely to improve as the riparian buffer continues to
develop a riparian canopy. In-stream vegetation treatments did not result in any collateral damage to
the native planted woody stems along the banks. Vegetation areas of concern will continue to be
monitored in MY4, and invasive species will continue to be treated throughout the post-construction
monitoring period as needed. Invasive species and vegetation areas of concern are documented on
Table 7 and shown on the Current Condition Plan View (CCPV) Figures 3.0 – 3.7 in Appendix 2.
Supplemental Planting and Areas of Low Stem Density
In March 2023, Wildlands supplementally planted approximately 0.1 acres of low stem density areas
previously documented in MY2. These areas were located near the confluence of WF Fishing Creek
Reach 1 and Shew Ridge Tributary Reach 2, and SF Fishing Reach 3, and represented by mobile
vegetation plot (MVP) 2, and permanent vegetation plot (VP) 12, respectively. MY3 vegetation data
collection and visual assessment showed that the March 2023 supplemental plantings improved the
stem density in and around MVP2 and VP12. However, the improved stem density in VP12 is not
reflected in the MY3 vegetation data since new stems must be documented for 2 consecutive years
before counting towards success criteria in the permanent plots. The supplementally planted stems will
be included in the MY5 vegetation data assessment. MVP6 has a stem density of 283 stems per acre
which does not meet the interim success criteria of 320 stems per acre in MY3. However, this area of
low stem density is isolated to mobile plot location, where planted stems have been outcompeted by
dense herbaceous vegetation. This mobile plot is still meeting the MY5 and MY7 stem density criteria,
therefore is not an area of concern. Supplementally planted areas are shown on the Current Condition
Plan View (CCPV) Figures 3.0 – 3.7 in Appendix 2.
Conservation Easement Boundary
In MY3, Wildlands documented 6 instances of damaged easement fencing associated with downed
trees, high flood waters, and one hay bale that accidentally rolled into the easement fencing. In the
summer of 2023, Wildlands and the landowner removed debris and repaired damaged segments of
fencing. Damaged fencing resulted in minor cattle encroachment; however, the cattle were removed
within 24 hours, and damage to planted stems was minimal.
In December 2023, vegetation maintenance under the overhead power line, within the utility easement,
was observed on Magnolia Trib Reach 2. Approximately 0.009 acres within the project boundary was
disturbed, primarily affecting volunteer box elder (Acer negundo). Wildlands will supplementally plant
this area with shorter shrub species in 2024.
Clearing for logging operations has occurred outside of the easement area on upper Magnolia Trib
Reach 1. No encroachments have been documented, Wildlands anticipates a heavy sediment load may
affect the downstream reaches. Wildlands will install silt fencing to reduce aggradation in Magnolia
Tributary. A full boundary inspection has been completed, and all fences on the Site are intact. No
additional encroachments were present as of December 2023.
1.2.3 Stream Assessment
Riffle cross-sections on the restoration reaches should be stable and should show little change in
bankfull area and width-to-depth ratio. Per NC IRT guidance, bank height ratios shall not exceed 1.2 and

Critcher Brothers Mitigation Site
Monitoring Year 3 Annual Report - DRAFT 1-5
entrenchment ratios shall be at least 1.4 for restored B-type channels and 2.2 for restored C-type
channels to be considered stable. All riffle cross-sections should fall within the parameters defined for
channels of the appropriate stream type. If any changes do occur, these changes will be evaluated to
assess whether the stream channel is showing signs of instability. Indicators of instability include a
vertically incising thalweg or eroding channel banks. Changes in the channel that indicate a movement
toward stability or enhanced habitat include a decrease in the width-to-depth ratio in meandering
channels or an increase in pool depth. Remedial action would not be taken if channel changes indicate a
movement toward stability.
Morphological surveys for MY3 were conducted in June 2023. Cross-section survey results indicate that
channel dimensions are stable and functioning as designed on all restoration and enhancement I
reaches with minimal adjustments. All 49 cross-sections are generally stable, with bank height ratios at
or near 1.0. Changes occurring within some cross-sections include slight variations in cross-sectional
areas and bankfull depths.
Pool cross-section 1 (SF Fishing Reach 2), riffle cross-section 22 (Critcher Tributary C), and pool cross-
section 34 (Robin Hill Tributary Reach 1) exhibited a reduction in depth and cross-sectional area in MY3
due to localized aggradation. MY3 survey revealed that cross-section 22 has maintained a similar cross-
sectional area and max depth when compared to as-built, and the riffle appears to have stabilized with
no signs of active instability. Though pool cross-section 1 has displayed some filling, it has maintained a
max depth and cross-sectional area within the reach’s design parameters. The cross-sectional area at
cross-sections 34 was significantly reduced in MY3 due to excess sediment along Robin Hill Tributary
Reach 1 from an off-project sediment source.
Visual sediment assessments revealed Oak Trib and Antioch Trib Reaches 2 and 3 also exhibited an
excess fine sediment load in MY3. Consistent channel bed and bank are still present on these reaches
and are still functioning as streams and not considered an area of concern. MY4 is a reduced monitoring
year; however, Wildlands will continue to visually monitor these reaches for signs of aggradation. Refer
to section 1.2.5 for a larger discussion about this area of concern Refer to Appendix 4 for morphological
tables and cross-section plots.
1.2.4 Stream Hydrology Assessment
Nineteen automated pressure transducers were installed on restoration and enhancement reaches
across the Site and are used to document stream hydrology throughout the seven-year monitoring
period. Automated transducers are programmed to record every 2 hours. Fifteen gages are
documenting bankfull events and are referred to as “crest gages” (CG). The remaining four gages
document both baseflow and bankfull events and are referred to as “stream gages” (SG).
Annual precipitation data is derived from the NC Cronos Station, North Wilkesboro 5.5 SE, NC. This rain
gage is located approximately 4 miles from the Site which is sufficiently close to provide accurate
precipitation data for the Site.
Bankfull Events
At the end of the seven-year monitoring period, four or more bankfull flow events must have occurred
in separate years within the restoration and enhancement level I reaches. At least one bankfull event
was documented on all required project reaches since the completion of construction and 15 of 19
(78%) reaches have documented 2 or more bankfull events in 3 separate years. 5 of 19 (26%) reaches
have documented 3 or more bankfull events in 3 separate years. Therefore, the performance standard
for bankfull events has been partially met for all reaches. Though several reaches, including Timber Trib
Reach 2, Robin Hill Trib Reach 1, and Robin Hill Trib B, have not yet recorded a bankfull event with the
pressure transducers, visual bankfull indicators have been documented on those reaches. In February

Critcher Brothers Mitigation Site
Monitoring Year 3 Annual Report - DRAFT 1-6
2023, Wildlands installed two additional crest gages on Timber Trib Reach 2 (CG18) and Robin Hill Trib
Reach 2 (CG19) to supplement existing crest gage data on these tributaries. CG19 recorded a bankfull
event on 6/20/2023. CG18 did not record a bankfull event, but visual bankfull evidence was documented
on Timber Trib Reach 2 on 12/14/2023. Wildlands will continue to document bankfull indicators such as
floodplain sediment deposits and debris wracklines on project reaches. In MY2, Wildlands requested the
bankfull requirement on Robin Hill Trib B (CG16) be omitted due to its steep A3 channel type. Wildlands
visually documented a bankfull event on this reach on 2/2/2023. Wildlands will continue to monitor in-
stream flow events on this reach. Per IRT request, Wildlands will install a game camera downstream of
CG16 in early MY4. Refer to Appendix 5 for hydrology summary data, and photographs of bankfull
evidence.
Baseflow Monitoring
During the seven-year monitoring period, consistent baseflow must be documented every year for at
least 30 consecutive days in low flow/intermittent channels that receive restoration or enhancement I
level approaches. Automated SGs were installed on the upper third of Critcher Tributary Reach 1,
Critcher Tributaries C and D, and Robin Hill Tributary A. In MY3, 4 of 4 (100%) low flow reaches exceeded
the success criteria for baseflow monitoring. Days of consecutive stream flow ranged from 109 days on
Critcher Trib Reach 1 to 305 days on Critcher Trib C. Refer to Appendix 5 for hydrology summary data
and plots.
1.2.5 Stream Areas of Concern and Proposed Management Activity
The MY3 visual assessment revealed that the majority (between 98% and 100%) of the project reaches'
bed and banks are stable and performing as intended with only minor instances of bank erosion,
localized aggradation and isolated structure issues. One beaver dams was documented and removed on
SF Fishing Reach 7 in MY3.
Bank Erosion
SF Fishing Reach 11, station 179+20 to 179+50 and Magnolia Trib Reach 2, station 809+95 to 810+15
exhibited approximately 20 to 30 LF of erosion and scour in MY3. Lack of established woody vegetation
resulted in localized segments of right bank erosion and scour. To stabilize these reaches, Wildlands will
implement bank repairs at these isolated locations. Repairs will likely include grading, matting, seeding
and adding livestake fascines to the floodplain and bank.
Aggradation
Robin Hill Tributary A, station 551+20 to 552+20 and Antioch Trib A, station 348+00 to 349+00
exhibited approximately 100 LF of aggradation in MY3. Loss of stream power due to reduction in
channel gradient promoted deposition of upstream sediments within the channel. Fine grain sediments
now dominate the channel bed, resulting in some loss of defined bed and bank on these reaches. To
address these issues, Wildlands will mobilize sediment along these reaches and install additional
livestakes on the banks to better define the channels.
Structure Erosion
A log sill on SF Fishing Reach 3, station 122+60 exhibited erosion around the structure, threatening the
bank stability due to concentrated flow vectors. A log sill on Robin Hill Trib Reach 2, station 508+75
became dislodged in MY3 and caused minor incision downstream of the dislodged log sill. To address
these issues, Wildlands will make hand repairs on the degraded structures.
The culvert at SF Fishing Reach 9, station 159+45 overtopped during large flow events and is exhibiting
erosion. The private property owner is responsible for maintenance and upkeep of the culvert.

Critcher Brothers Mitigation Site
Monitoring Year 3 Annual Report - DRAFT 1-7
Wildlands will closely monitor the area to ensure that erosion does not extend beyond the easement
exclusion area and into the conservation easement.
Wildlands will continue to monitor all areas of concern and document repairs and management
activities in the MY4 report. Refer to Appendix 2 for stream stability tables, area of concern photos,
CCPV Figures 3.0 – 3.7, and the Areas of Concern (AOC) and Management Activities Tables.
1.2.6 Completed Stream Adaptive Management Activities
Each of the MY2 areas of concern have been stabilized, except for one structure issue on Robin Hill Trib
Reach 2, which has been added to the MY3 Areas of Concern list. Refer to Appendix 2 for stream the
AOC and Management Activities Tables and the Stream Management Activity Photographs.
 MY2-4 – SFFC Reach 3, station 121+55 to 121+70 – Wildlands added live stakes to the affected
bank in February 2023. The area has stabilized and is no longer an area of concern.
 MY2-5 – SFFC Reach 11, station 168+90 to 169+20 – Wildlands periodically mobilized sediment
on the edges of the bar. Vegetation growing on the bar received herbicide applications in June
2023. While portions of the bar are still present, the area has stabilized and is no longer an area
of concern.
 MY2-6 – WFFC Reach 3, station 714+00 to 714+15 – Wildlands cut several low hanging branches
and cleared the debris jam. Live stakes were added to the affected bank in February 2023. While
portions of the downed tree are still present, the area has stabilized and is no longer an area of
concern.
 MY2-7 – Robin Hill Trib Reach 1, station 503+00 – Wildlands added tree branches above the
swale to diffuse the flow path, and the swale was re-seeded in March 2023. The area has
stabilized and is no longer an area of concern.
 MY2-8 – Robin Hill Trib Reach 2, station 508+75 – Wildlands replaced the filter fabric on the log
sill to prevent it from piping. In MY3, the log sill became dislodged. This area has been added to
the MY3 AOC list and will be addressed in MY4.
 MY2-9 – Critcher Tributary Reach 3 BMP, station 209+00 – Wildlands filled the void space
behind the log sill with rock, woody debris, and soil in May 2023. The area has stabilized and is
no longer an area of concern.
In MY3, Wildlands documented several areas of concern that required hand repairs in MY3.
 MY3-1 – Ironwood Trib Reach 1, station 1002+00 – Wildlands observed rilling in the right
floodplain and stabilized the area by installing coir logs in April 2023 to diffuse the flow path.
The area has stabilized and is no longer an area of concern.
 MY3-2 – Robin Hill Trib Reach 1, station 500+60 – Wildlands observed excess sediment
throughout Robin Hill Run Reach 1 and determined it was caused by an erosional feature
upstream of the jurisdictional stream. Wildlands installed coir logs upstream of the jurisdictional
stream in November 2023 to diffuse the flow path and capture sediment.
1.3 Monitoring Year 3 Summary
Overall, the Site has met the required stream, vegetation, and hydrology success criteria for MY3. The
overall average planted stem density for the Site is 497 stems per acre and is on track to meet the MY5
requirement of 260 stems per acre. Geomorphic surveys indicate that cross-section bankfull dimensions
closely match the baseline monitoring with some minor adjustments, and streams are functioning as
intended. At least one bankfull event was documented on all required project reaches since the
completion of construction and 15 of 19 reaches have documented 2 or more bankfull events in 3
separate years. The MY3 visual assessment identified a few areas of concern including small populations

Monitoring Year 3 Annual Report - DRAFT 1-8
of invasive plant species or minor instances of scour, erosion, or aggradation. Adaptive management will
be implemented as necessary throughout the seven-year monitoring period to benefit the ecological
health of the Site.

2.  Pattern and profile will be assessed visually during semi-annual site visits. Longitudinal profile was collected during as-built baseline monitoring survey only, unless observations indicate widespread lack of vertical stability (greater than
10% of reach is affected) and profile survey is warranted in additional years to monitor adjustments or survey repair work.
1.  Cross-sections were permanently marked with rebar to establish location. Surveys include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and thalweg.
3. Riffle 100-count substrate sampling were collected during the baseline monitoring only. Pebble counts will not be conducted during the remaining monitoring years unless requested by the IRT or deemed necessary based on best
professional judgement.
4.  Crest gages and/or stream gages will be inspected and dowloaded quarlerly or semi-anually, evidence of bankfull events will be documented with a photo when possible. Transducers, if used, will be set to record stage once every 2
hours. The transducer will be inspected and downloaded semi-annually.
5.  Both mobile and permanent vegetation plots will be utilized to evaluate the vegetation performance for the open areas planted. 2% of the open planted acreage will be monitored with permanent plots and mobile plots. Permanent
vegetation monitoring plot assessments will follow CVS Level 2 protocols. Mobile vegetation monitoring plot assessments will document number of planted stems, height, and species using a circular or 100 meter square/rectangular plot.
Planted shaded areas will be visually assessed.
6. Locations of exotic and nuisance vegetation will be mapped.
7. Locations of vegetation damage, boundary encroachments, etc. will be mapped.

MEMORANDUM FOR RECORD

SUBJECT: Action ID # SAW-2017-01913, NCIRT Review Comments on the Wildlands
Yadkin Valley Umbrella Mitigation Bank, Critcher Brothers Year 2 Monitoring Report

Todd Bowers, USEPA:

I have reviewed the Monitoring Year 2 (MY2) monitoring report for the Critcher
Brothers mitigation site (a component of the Yadkin Valley Umbrella Mitigation
Bank) dated February 2, 2023 submitted by Wildlands Engineering, Inc (WEI). The
project includes the restoration, enhancement, and preservation of 27,938 linear feet
(LF) of stream on South Fork Fishing Creek, West Fork Fishing Creek, and 22
tributaries. At the time of as-built, the Site was determined to generate 20,578.400 cool
stream mitigation units (SMUs). With additional enhancement II work completed on
Magnolia Tributary at the IRT’s request, the net credits have increased by 13.333 SMU
to a total of 20,591.733 SMU.

Per WEI, MY2 site assessments were conducted between January 2022 and January
2023. Overall, the Site has met the required stream, vegetation, and hydrology success
criteria for MY2. The project streams are in good condition and functioning as intended,
with only minor instances of scour identified. At least one bankfull event has been
documented on 80% of the project reaches since the completion of construction.
Vegetation assessments indicated an average planted stem density of 429 stems per
acre and the Site is on track to meet the MY3 requirement of 320 stems per acre. While
over 99% of the Site is free of invasive species, a few small populations of invasive
plant species were identified in 2022. Wildlands will continue to monitor all areas of
concern and document repairs and management activities in the MY3 r eport. Wildlands
is requesting 2,010.21SMUs be released for successful completion of MY2 activities
and demonstrating that interim performance standards are being met.

Overall, I am very pleased with the report and the work that has been completed at the
site as well as efforts towards adaptive management and corrective actions for culvert
retrofits, stream repairs, beaver removal, supplemental planting plans and invasive
species treatments. The following additional items in the MY2 were noted:

• Areas of low stem density are located along WF Fishing Creek Reach 1, Shew
Ridge
Tributary Reach 2, and SF Fishing Reach 3 and are represented by mobile vegetation
plots 1 and 2, and permanent plot 12, respectively. Management activities are planned
for winter 2023, and areas of low stem density will be supplementally planted with
approved species from the project’s Final Mitigation Plan. No concerns.
-2-

• During MY2, Wildlands documented 3 instances of cattle encroachment within
the easement that have been resolved. Wildlands and landowner are actively
collaborating on repairs and prevention of further instances. No concerns.
• All 49 stream cross-sections are stable, with bank height ratios at or near 1.0.
Minor stream adjustments/instabilities and locations and outlined in the report
along with photos. Corrective actions were outlined in Section 1.2.5. No
concerns.
• Wildlands has requested that the bankfull requirement on Robin Hill Trib B
(CG16) be omitted. This tributary is a steep A3-type channel, and therefore
unlikely to have a bankfull event. I concur with this assessment and approve the
request.
• Only 75% (3 of 4) low flow reaches (intermitted flow regime) exceeded the
success criteria for baseflow monitoring with streams ranging from 4 to 365 days
of consecutive of stream flow. Noted; no concerns as last year all reaches
attained success.
• In July 2022, three beaver dams were identified and removed from SF Fishing
Reach 7 and WF Fishing Creek Reach 1. Wildlands is monitoring and removing
as needed. Noted.
• In the MY1 report, Wildlands documented several areas of concern that required
mechanical repairs in MY2. All repairs were completed in August 2022 and
repairs on WF Fishing Reach 5 included grading, matting, seeding, and adding
livestake fascines to the floodplain and banks. The photos are appreciated.
• No site visit requested.

Thank you for the opportunity to review and provide comments on the Critcher Brothers
Mitigation Site MY2 monitoring report. Having not been on-site, I really appreciated all
the photos in the report. I recommend the appropriate credit release for cool stream
SMUs for monitoring milestone 4. If you or the sponsor have any questions, please do
not hesitate to contact me.

Casey Haywood, USACE:
1. Repairs: Good photo documentation. The repairs on WF Fishing Reach 5 and
SG Fishing Reach 11 look good, and the seeding and soil amendments in 2022
on Critcher R3 appear to have been successful. Please include photos of the
2023 planned repairs in next year’s report.
2. Vegetation: Noted that three veg plots are not meeting MY3 success. Low stem
density areas will be supplementally planted in 2023. Please include a discussion
of the management activities in next year’s report to include any management of
herbaceous vegetation. Are the 77 American sycamore stems in permanent plot
4 a reporting error?
3. Cross-sections: Thank you for providing the detailed information regarding cross-
section observations. Several of the cross-sections appear to be stable from last
year. Noted minor aggradation on XS40, likely from the beaver dam. Please
continue to monitor these areas and note in future reports.
-3-

4. Stream AOC: To confirm, have all AOCs listed in the MY1 report been addressed
and/or stabilized on their own? These areas include: floodplain scour Antioch R4
STA 313+50, aggradation (possible mid-channel bar formation) SFFC R9
164+70, and left bank scour on SFFC R10 XS12. Given the number of repairs
and size of the site, it would be helpful to have the repairs listed in a tabular
format.
5. Murdannia was treated in 2022. If more treatments are anticipated, please pay
close attention to live stake survival, and supplementally plant additional live
stakes as needed. Please include these areas on the CCPV in next year’s report
if the problem worsens.
6. Three instances of cattle encroachment occurred during the monitoring year due
to fencing issues. These areas were repaired, and no damage was observed in
the easement. Noted.
7. Flow: SG2 on Critcher Trib R1 only recorded 4 days of consecutive flow (48
cumulative) but met last year. Recommend installing a game cam to help
supplement flow data if the reach doesn’t meet in MY3.
8. Culvert photo- Antioch Trib A R1: There is a large rock in front of the culvert. Has
it always been there? In last year’s photo it looked like a clump of fescue. Is the
culvert perched?
9. Bankfull: No bankfull events on Robin Trib B or R1, Timber R2, and SFFC R6 in
MY1 or MY2. However, bankfull indicators were observed on SFFC R6. Were
any bankfull indicators observed on the other reaches? Recommend including
photo documentation of observations to help supplement future reports.
10. Wildlands requested the bankfull requirement on Robin Hill Trib B (CG16) to be
omitted due to the steep A3-type channel. Since this is a restoration reach, the
crest gauge should remain in place and a camera needs to be installed to help
monitor flow. This reach was listed as perennial, but the graph indicates that the
system may be acting more as an intermittent tributary.

that required mechanical repairs in MY2. All repairs were completed in August 2022 and repairs on
WF Fishing Reach 5 included grading, matting, seeding, and adding livestake fascines to the floodplain
and banks. The photos are appreciated.
Wildlands’ Response: Noted
Todd Bowers, USEPA Comment #9: No site visit requested.
Wildlands’ Response: Noted
Casey Haywood, USACE Comment #1: Repairs: Good photo documentation. The repairs on WF
Fishing Reach 5 and SG Fishing Reach 11 look good, and the seeding and soil amendments in 2022
on Critcher R3 appear to have been successful. Please include photos of the 2023 planned repairs
in next year’s report.
Wildlands’ Response: Repairs and management activities are reported in Section 1.2.5 and in Table 8.
Casey Haywood, USACE Comment #2: Vegetation: Noted that three veg plots are not meeting MY3
success. Low stem density areas will be supplementally planted in 2023. Please include a discussion
of the management activities in next year’s report to include any management of herbaceous
vegetation. Are the 77 American sycamore stems in permanent plot 4 a reporting error?
Wildlands’ Response: A discussion of vegetation management activities is located in Section 1.2.2. In
MY2, there were 77 volunteer American sycamore stems in permanent vegetation (VP) plot 4. In MY3,
there were 67 volunteer American sycamore stems in VP4. American sycamore volunteers are small and
are not interfering with the health of the planted stems.
Casey Haywood, USACE Comment #3: Cross-sections: Thank you for providing the detailed
information regarding cross- section observations. Several of the cross-sections appear to be stable
from last year. Noted minor aggradation on XS40, likely from the beaver dam. Please continue to
monitor these areas and note in future reports.
Wildlands’ Response: Cross-sections initially mentioned in the MY2 report have stabilized in MY3.
Wildlands will continue to monitor cross-sections throughout the Site, and report areas of concern in the
annual monitoring report. Refer to section 1.2.3 Stream Assessment in the MY3 report.
Casey Haywood, USACE Comment #4: Stream AOC: To confirm, have all AOCs listed in the MY1
report been addressed and/or stabilized on their own? These areas include: floodplain scour Antioch
R4 STA 313+50, aggradation (possible mid-channel bar formation) SFFC R9 164+70, and left bank
scour on SFFC R10 XS12. Given the number of repairs and size of the site, it would be helpful to have
the repairs listed in a tabular format.
Wildlands’ Response: All AOC’s reported in MY1 have stabilized. Wildlands has added Table 8: Areas of
Concern and Management Table to Appendix 2 of the report. The MY4 report will include a photolog of
all former areas of concern.

Wildlands Engineering, Inc.  phone [phone]  fax [phone]  1430 S. Mint Street, # 104  Charlotte, NC 28203

Casey Haywood, USACE Comment #5: Murdannia was treated in 2022. If more treatments are
anticipated, please pay close attention to live stake survival, and supplementally plant additional
live stakes as needed. Please include these areas on the CCPV in next year’s report if the problem
worsens.
Wildlands’ Response: On-site murdannia was greatly reduced after treatments in MY2. In June 2023,
murdannia was treated on SFFC Reaches 9 and 10, with no damage to livestakes. These areas are
mapped on the CCPV.
Casey Haywood, USACE Comment #6: Three instances of cattle encroachment occurred during the
monitoring year due to fencing issues. These areas were repaired, and no damage was observed in
the easement. Noted.
Wildlands’ Response: Noted
Casey Haywood, USACE Comment #7: Flow: SG2 on Critcher Trib R1 only recorded 4 days of
consecutive flow (48 cumulative) but met last year. Recommend installing a game cam to help
supplement flow data if the reach doesn’t meet in MY3.
Wildlands’ Response: SG2 on Critcher Trib Reach 1 recorded 109 days of consecutive flow in MY3.
Wildlands does not currently see a need for a game camera at this time.
Casey Haywood, USACE Comment #8: Culvert photo- Antioch Trib A R1: There is a large rock in
front of the culvert. Has it always been there? In last year’s photo it looked like a clump of
fescue. Is the culvert perched?
Wildlands’ Response: The MY1 report documented the culvert crossing located on Antioch Trib A Reach
1. The MY2 report documented the crossing located on Antioch Trib Reach 4 but was mislabeled. The
MY1 and MY2 reports did not document both culvert crossings located on the Antioch Tributaries. Both
culvert crossings have been documented in the MY3 report. The large rock in front of the Antioch Trib
Reach 4 culvert has always been there, and the culvert is not perched.
Casey Haywood, USACE Comment #9: Bankfull: No bankfull events on Robin Trib B or R1,
Timber R2, and SFFC R6 in MY1 or MY2. However, bankfull indicators were observed on SFFC
R6. Were any bankfull indicators observed on the other reaches? Recommend including photo
documentation of observations to help supplement future reports.
Wildlands’ Response: Wildlands will continue to document bankfull indicators on all reaches to
supplement or verify crest gage data.
Casey Haywood, USACE Comment #10: Wildlands requested the bankfull requirement on
Robin Hill Trib B (CG16) to be omitted due to the steep A3-type channel. Since this is a
restoration reach, the crest gauge should remain in place and a camera needs to be installed
to help monitor flow. This reach was listed as perennial, but the graph indicates that the
system may be acting more as an intermittent tributary.
Wildlands’ Response: Wildlands will install a game camera on Robin Hill Trib B in MY4.
