RE: Response to Draft MY2 Monitoring Report Comments dated November 30, 2021
Greenbrier Stream Mitigation Site
Yadkin River Basin — CU# 03040101- Yadkin County, North Carolina
NCDMS Project # 100086, Contract # 7616
Dear Mr. Wiesner,
Ecosystem Planning and Restoration (EPR) has reviewed the comments on the Draft MY2
Monitoring Report provided November 30, 2021. The comments have been addressed as described
below and the Final Baseline Report and electronic deliverables have been revised in response to
this review.
• Table 1. Project Mitigation Quantities and Credits: The thermal regime for the project
streams is "warm". Please update the table accordingly.
• Thermal Regime in Table 1 has been updated. The Microsoft Excel version of Table
1 in the electronic support files has been updated as well.
• Section 2.2.1 Vegetation Monitoring Data - Please discuss the average tree heights in the
vegetation plots assessed and (although early) note if the project vegetation appears to be
on track to meet the year 5 interim height success criteria.
• A discussion regarding plot height has been added to Section 2.2.1.
• CCPV Maps: The overview map is incorrectly labeled as MYO: 2020. The aerial orthoimagery
is from 2018. Please update the maps if more recent aerial imagery is available. Please
QA/QC the CCPV maps and update as necessary.
• The date on the overview maps has been updated. The 2018 aerial orthoimagery
shown in the CCPV is the latest aerial image available for the project area. EPR will
update these images in future monitoring years as new imagery becomes available.
• Table 4 (a-d) & Table 5 - Please include the date that the project was visually assessed at the
top of each table. This was an IRT request at the 2021 credit release meeting.
• The project assessment dates have been included in Tables 4 and 5.

• Appendix A. Monitoring Year 2 (2021) -Photo Point Logs: Please provide dates for all
project photo points. If exact dates cannot be provided, please include the month and year for
each photo.
• Dates have been included for all project photo points.
• Report Text and Appendix 8: In the revised report (Appendix B), please provide a planting
map and species list from the March 2021 supplemental planting effort reported in Section
2.2.1 Vegetation Monitoring Data. Please reference the planting map and species list in the
report text.Please also report what percentage of the initial planted area was supplementally
planted in MY2(2021). The supplemental planting area should also be included on the MY2
CCPV maps.
• A planting species list has been included in Appendix B, and the planted areas are
now shown on the CCPV. The map and species list are referenced in section 2.2.1
Vegetation Monitoring Data. The approximate percentage of the original planted
area has also been included in this section.
Table 7. Vegetation Performance Standards Summary Table: Please report the average
vegetation plot height in the summary table.
• Average height has been included in Table 7. The average height reported in the
document was calculated from the stem height in the input file for the vegetation
tool. The vegetation tool rounds these heights to whole numbers so that is why
they are presented this way in the tables.
Electronic Support File Comments:
The submitted input template for the DMS Veg tool cannot reproduce the tables included in the
report. Several issues were identified:
The fixed plot data for years 0 and 1 are not consistent with previously submitted veg data.
This is likely because not all dead stems were retained in the plot specific excel sheets.
• Fixed plot data for years 0 and 1 have been updated in the input file and the plot
data is now consistent from year to year. The draft submittal only included stems
that were still living in MY2, but all stems will be included in this data moving
forward.
• A formula was used to calculate stems per acre for fixed plot 4 in the Post Mitigation Plan
Performance Standard section, the Current Year Stem Count was changed, and species count
was changed.
• The formula was used to calculate the total stems per acre for plot 4 because of a
misunderstanding about what the Post Mitigation Plan Performance Standard row

was meant to show. This has been corrected for the final submittal and only the
output that was produced by the DMS vegetation tool is included.
• One stem in the random plot 5 tab does not have a height.
• The stem in Random Plot 5 has been updated to include a height.
• Please do not edit the output of the tool — the logic used to calculate these output values is
based on the current IRT requirements. To ensure that output data is consistent for the
Vegetation Performance Standards Summary Table, be sure to maintain a record of each
stem in the input across monitoring years. If the stem dies, do not include a height in the
current monitoring year's height column but keep the record of the stem in the input. There
is an example dataset for reference that can be downloaded from the application. DMS has
also included an example using Greenbrier veg data for Fixed plot 1 and Random Plot Group
5.
• The output of the vegetation tool has not been edited for the final submission. This
practice will be used moving forward for future monitoring submittals.
Please include a feature representing the supplemental planting areas and display this in
the CCPV map/s.
• The shapefile Greenbrier _2021_Planting_Zones has been added to the electronic
submission CCPV folder. This shapefile has been included in the CCPV.
If you have any questions regarding the MY1 Monitoring Report, please contact me at 919-623-5411

1.0 PROJECT SUMMARY
Ecosystem Planning and Restoration, PLLC (EPR) implemented the Greenbrier Stream Mitigation Project
(Project; Site) for the North Carolina Division of Mitigation Services (NCDMS) to provide 2,300 stream
mitigation credits (SMCs) in the Yadkin River Basin, Hydrologic Unit Code (HUC) 03040101. The Project
was instituted via NCDEQ-DMS RFP # 16-007406. The Project restored and enhanced 2,530 linear feet
(LF) of one perennial (UT1) and three intermittent (UT1A, UT1A-1, and UT1B) unnamed tributaries (UT)
to South Deep Creek within a 6.7-acre conservation easement. Mitigation assets are listed in Table 1.
The Site is located in DMS targeted local watershed 03040101130020. The Site was historically utilized
for agricultural and cattle practices. As such, streams and existing wetlands in the project area were
adversely impacted by direct cattle access, farming activities, and stream channelization. The Site is
situated on once active pastureland in a WS-III watershed that is approximately 49% agricultural land,
42% forest, and 8% developed land, including open space and low intensity development. Prior to
construction activities, project streams were incised, straightened, and suffered from significant damage
from cattle. The adjacent wetlands were small, but similarly trampled, and heavily grazed. Pre -
construction, or pre-existing, site conditions are provided in Table 8 of Appendix C. Photos and a more
detailed description of Site conditions before restoration are available in the Mitigation Plan (Final
version submitted December 2019).
1.1 Goals and Objectives
The Project goals were established based on an assessment of site conditions and restoration potential
with careful consideration of the stressors identified in the Upper Yadkin Pee -Dee River Basin
Restoration Priorities (RBRP) report (NCEEP, 2009) and Yadkin Pee -Dee Basinwide Water Quality Plan
(NCDWQ, 2008). These goals and objectives are presented in Table 2.
Site construction, planting, and baseline vegetation data collection were completed in April 2020 and
the as -built survey was completed in May 2020. A detailed timeline of the Project activity and reporting
history is provided in Appendix E.
1.2 Performance Criteria
Project success criteria were established in accordance with the NCDMS Mitigation Plan Template (ver.
06/2017), and U.S. Army Corps of Engineers — Wilmington District Public Notice: Notification of Issuance
of Guidance for Compensatory Stream and Wetland Mitigation Conducted for Wilmington District
(October 24, 2016). The monitoring plan for the site follows the guidance NCDMSAnnual Monitoring
Report Format, Data, and Content Requirements (October 2020). Table 2 details the United States Army
Corps of Engineers (USACE) success criteria that evaluate whether project goals have been met
throughout the monitoring period.

Year 2 Monitoring Report - FINAL
DMS Project ID #100086
Yadkin County, North Carolina

2.0 MONITORING DATA ASSESSMENT
Monitoring Year 2 (MY2) data was collected in July and October 2021. Current site conditions and
monitoring data are described in the following sections to evaluate whether the project is meeting the
success criteria established in the mitigation plan.
2.1 Stream Monitoring
Stream monitoring involves field data collection to assess the hydrologic and geomorphic functions of
UT1, UT1A, and UT1B. Monitored parameters, methods, schedule/frequency, and extent are
summarized in Table 2. These monitoring parameters follow USACE guidance but will also allow for
monitoring of other parameters to document site performance related to the project goals listed in
Table 2. The locations of the established monitoring cross sections and stream gauges are shown in
Figure 2 Current Condition Plan View (CCPV).
2.1.1 Stream Profile
A full longitudinal profile was surveyed for the entire length of the restored streams in May 2020 to
document as -built conditions. This survey was tied to a permanent benchmark and includes thalweg,
right bank, and left bank features. Profile measurements were taken at the head and tail of each riffle,
inverts of in -stream structures, and at the max depth of pools. The longitudinal profile will not be
surveyed during annual monitoring unless vertical channel instability has been observed during
monitoring and remedial actions or repairs are needed.
2.1.2 Stream Dimension
Eight (8) permanent cross sections were installed across the site; 6 on UT1 and 1 each on UT1A and
UT1B. Five (5) cross sections were installed in riffles and three (3) were installed in pools. Each cross-
section was marked using a length of rebar and steel t-posts on both streambanks. The location and
elevation of each pin was recorded to facilitate data comparison from year to year. Cross -sections were
surveyed using a Topcon RL-H5A Self Leveling Laser Level. Reported data includes measurements of
bankfull elevation (based on the as -built bankfull area), bank height ratio (based on the as -built bankfull
area), thalweg elevation, elevation of the low top of bank, maximum depth from the low top of bank,
and low top of bank cross -sectional area (Appendix C). Stream dimension measurements were made
using the NCDMS cross section tool (Version 5/11/2021). Reference photos were taken of both
streambanks to provide a visual assessment of any changes that may have occurred since the previous
monitoring year.
The Year 2 monitoring cross-section survey indicates that the project streams are stable and restored
channel dimensions have not changed significantly during Monitoring Year 2. Cross sections were shot in
October 2021 at the end of the growing season. At this time, portions of the stream channels still had
vegetation growing in them, which affected the cross-section plots slightly. Every effort was made to
survey the existing stream channel bottom and not the vegetation, but some of the cross -sections (XS3,
XS5, XS7, and XS8) indicate that the channels appear to be temporarily aggraded. EPR does not believe
this will be a long-term issue as the planted riparian trees and shrubs will begin to shade out the
herbaceous vegetation growing in the channels. The riffle cross -sections, apart from XS8, showed only
minor fluctuations compared to the as -built conditions and all restored streams meet the success
criteria for restored stream channels as established in the mitigation plan and shown in Table 2. The
cross-section plots, photos, and data summary (Table 9) are included in Appendix C.

2.1.3 Channel Stability
Channel stability is assessed on a yearly basis using photographs to visually document the condition of
the restored project streams. Photographs are taken from the same location in the same direction each
year. Sixteen (16) photo points were established during baseline monitoring and are shown in Appendix
A. The locations of each permanent photo point are shown in the CCPV (Figure 2). Visual assessments of
channel stability and in -stream structure condition were also made regularly throughout Monitoring
Year 2.
Stream photo points and visual assessments indicate that all restored channels and in -stream structures
are in good condition and performing as intended. No significant stream problem areas were observed.
The minor floodplain rilling along UT1 Reach 1 that was noted in the MY1 report has mostly stabilized
and these areas are covered with dense herbaceous vegetation. Some sections of the restored channels
also contain this herbaceous vegetation as well; however, it does not appear to be causing any
significant problems. EPR believes this is a temporary issue and the vegetation should wash through the
channel during the dormant season and eventually be shaded out by streamside trees and shrubs.
2.1.4 Stream Hydrology
Three (3) pressure transducers were installed in UT1, UT1A, and UT1B to document stream flow and the
occurrence of bankfull events within the monitoring period. The locations of these gauges are shown in
the CCPV (Figure 2). All three gauges were installed in the downstream end of pools. The constructed
bankfull elevation at each gauge was recorded, as well as the elevation of the downstream controlling
grade. These elevations are compared with the gauge readings to determine whether the stream is
flowing and if a bankfull event has occurred.
This Project utilizes a tipping bucket rain gauge installed at another EPR-completed stream restoration
approximately 0.75 miles to the southeast (Meadowbrook, DMS project no. 100024) to accurately
document rainfall at the Site. The rainfall data can be compared to the flow gauge data to verify that
high flows at the Site are correlated with rainfall events. The monitoring gauges were downloaded
regularly throughout Monitoring Year 2. Rainfall data is presented in Figure 3. Monthly Rainfall Summary
Data and the precipitation and water level hydrographs are included in Appendix D. When the rain
gauge was downloaded during MY2 monitoring in October 2021, it was determined that the batteries in
the logger had expired around 9/2/2021. For this reason, no rainfall data was collected for September
and October. The batteries were replaced in early November 2021.
Flow gauge data from MY2 indicate that all three project streams met the established success criteria of
30 days or more of consecutive flow throughout the year. According to the gauge for UT1 (SG-1), the
stream had 294 days of consecutive flow and 1 bankfull event during Monitoring Year 2. SG-2, located in
UT1A, documented consistent flow throughout the year, though bankfull events were difficult to
accurately verify. The water level shown by SG-2 exceeds the bankfull elevation for the entirety of June
through October, which is likely not accurate. EPR believes that vegetation growing in the channel
combined with fine sediment accruing around the gauge artificially increased the pressure that was
recorded. Because UT1A is such a small channel, any minor change in channel conditions could
significantly influence the gauge readings. All stream gauges will be manually cleaned out prior to MY3
monitoring to prevent this from becoming an ongoing issue. SG-3, which is installed in UT1B,
documented 186 days of consecutive flow. SG3 did not record any bankfull events.

2.2 Riparian Vegetation Monitoring
Riparian vegetation monitoring evaluates the growth and development of planted and volunteer
vegetation across the site. Monitored parameters, methods, schedule/frequency, and extent are
summarized in Table 2. These monitoring parameters follow USACE guidance but will also allow for
monitoring of other parameters to document site performance related to the project goals listed in
Table 2.
2.2.1 Vegetation Monitoring Data
Four (4) permanent vegetation monitoring plots were monitored across the site. The corners of the
permanent vegetation plots were marked using steel t-posts and the location of each plot was surveyed
during the as -built survey. The individual trees within each permanent plot were flagged and identified
to facilitate repeat monitoring each year. In addition to the 4 permanent plots, 2 randomly placed
vegetation plots are established each vegetation monitoring year and the location of these plots is
recorded using GPS. All vegetation plots for MY2 are shown in the CCPV (Figure 2). Annual vegetation
data was compiled and summarized using the DMS Vegetation Data Entry Tool (Version 8/23/2021).
The Greenbrier conservation easement area was supplementally planted in March 2021 in response to
areas of low growth and stem count in Monitoring Year 1. Vegetation across the majority of the site was
performing well in MY1 so these areas were only supplementally planted using a low stem density. Two
areas (the left terrace along UT1 Reach 1 and the floodplain along lower UT1 Reach 3) were replanted
using a higher number of stems because the trees in these areas had been smothered by dense
herbaceous vegetation in MY1. A total of 1.28 acres were replanted (500 stems per acre) and 3.19 acres
were supplementally planted (200 stems per acre). A total of 71% of the original planted area was
replanted in 2021, but most of this was done using a low stem density. The supplementally planted
areas are shown in the CCPV (Figure 2). A planted species list is provided in Appendix B and matches the
species in the approved mitigation plan that were originally planted after construction.
Year 2 vegetation monitoring occurred in July 2021 before leaf drop. Stem counts for the vegetation
plots (fixed and random) ranged from 10 trees per plot (405 trees per acre) in VP-4 F (Fixed) to 20 trees
per plot (810 trees per acre) in VP-6 R (Random). The average stem density from all 6 vegetation plots
(fixed and random) was 15 trees per plot (625 trees per acre). Therefore, the vegetation plot data
indicates that planted trees on the Site are meeting the interim success criteria of 320 stems/acre in
Monitoring Year 3. Average planted stem height for Monitoring Year 2 was 1.7 feet, which reflects the
fact that many of these trees were planted in early 2021 during the supplemental planting effort.
Success criteria for stem height does not take effect until MY5, but stem height will be continually
monitored for MY3 and MY5 to determine whether the site appears to be on track to meet the
performance criteria in MY5.
A small patch of Chinese privet (<0.1 acres) was observed on the right bank of UT1 Reach 2. This will be
sprayed and removed in early MY3. No other invasive species were found on the mitigation site.
