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 & Table 3. Project Attribute Table: The thermal regime for the project streams is "warm". This was a typo/mistake in the approved mitigation plan that DMS did not catch in the review. Please update the tables accordingly." o Tables 1 and 3 have been updated to reflect warm thermal regime. • CCPV Maps: Since VP-4 is not meeting the MY3 interim success criteria of 320 stems/acre, it should be shown as "red"on the CCPV Maps. This should be updated in the MY2 report once the supplemental planting effort is completed and the plot meets the success criteria. o VP-4 and RVP-1 are now shown as red on the CCPV maps. • Table 6 & Table 7: Recommend showing the VP-4 stems/ acre cells (162 stems/ acre) as orange/red since it is not meeting the MY3 interim success criteria of 320 stems/acre. o The cells on Tables 6 and 7 showing the 162 stems/acre have been shaded red. Electronic Support File Comments: • Please provide the spatial feature used to display the vegetation problem area in Fig. 28. o The spatial feature shapefile Greenbrier Veg Problem Areas has been added to the digital submittal. • In an effort to ensure that DMS has features that represent the creditable lengths or areas, the mitigation plan features were reviewed. In the mitigation plan design features, UT18 has a length of 232 ft, but is reported as 247.5 ft in the asset table.

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 cattle damage.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 NCDMS Annual 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.

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 1.0, 2020). 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 1 monitoring cross-section survey indicates that the project streams are stable and restored channel dimensions have not changed significantly during Monitoring Year 1.The pool cross sections have deepened slightly since the as-built survey but do not appear to be degrading. The riffle cross- sections showed only minor fluctuations compared to the as-built condition and all restored streams meet the success criteria for restored stream channels as established in the mitigation plan and shown in Table A.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 the CCPV Greenbrier Stream Mitigation Project Year 1 Monitoring Report-FINAL 6 DMS Project ID#100086 r�� Yadkin County,North Carolina (Figure 2). Visual assessments of channel stability and in-stream structure condition were also made regularly throughout Monitoring Year 1. 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 after construction 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 material should wash through the channel during the dormant season. 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 will be compared with the gauge readings to determine whether the stream is flowing and if a bankfull event has occurred. Photos will be taken of flood indicators such as debris lines and sediment deposition on the floodplain whenever it is apparent that 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 1 and rainfall data is presented in Figure 3. Monthly Rainfall Summary Data and the flow gauge plots are in Appendix D. When the rain gauge was downloaded during MY1 monitoring in October 2020, there were several spider webs built inside the tipping bucket that could have been impacting the mechanism that records rainfall.This could have altered the rainfall data presented in Appendix D, but it is difficult to determine with certainty. Measures will be taken to ensure this will not happen in future monitoring years. Flow gauge data from MY1 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 consistent flow throughout the year and the gauge documented 6 separate bankfull events. SG-2, located in UT1A, documented consistent flow throughout the year as well as 4 bankfull events. SG- 3, which is installed in UT1B, documented 134 days of consecutive flow from June 16, 2020 to October 27, 2020 when the gauge was last downloaded. SG3 also recorded 10 separate bankfull events. These numerous events along UT1B are likely influenced by UT1B's proximity to a wetland area and strong ground water interaction. Additionally, these small headwater reaches have very low top of bank depths and flood flows can easily spill out onto the floodplain. This reach is performing as intended and the number of bankfull events is not concerning along this reach. Bankfull events were further documented by photographs of other flood indicators, which are provided in Appendix A.The date and timing of these bankfull events correlated with significant rainfall events recorded by the tipping bucket rain gauge. Greenbrier Stream Mitigation Project Year 1 Monitoring Report-FINAL 7 DMS Project ID#100086 r�� Yadkin County,North Carolina 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 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 year and the location of these plots is recorded using a GPS. All vegetation plots for MY1 are shown in the CCPV(Figure 2). Annual vegetation data was compiled and summarized using the DMS Vegetation Data Entry Tool. Year 1 vegetation monitoring occurred in October 2020 before leaf drop and more than 180 days after planting. Stem counts for the vegetation plots (fixed and random) ranged from 4 trees per plot(162 trees per acre) in VP-4 F (Fixed)to 24 trees per plot(972 trees per acre) in VP-6 R (Random).The average density of stems from all 6 vegetation plots (fixed and random)was 12 trees per plot (486 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. One vegetation problem area is noted in Figure 2. As indicated by the low stem count in VP-4 F (4 trees), the downstream riparian area of UT1 Reach 3 is covered in dense herbaceous vegetation that seems to have outcompeted the bare root trees that were planted in early 2020.This area covers around 1 acre and will be replanted in 2021. No other vegetation problem areas were noted in MY1. Riparian herbaceous and woody vegetation that was established after construction appears to be flourishing throughout the site. Additionally, no invasive species were noted within the conservation easement.

The outcome resulted in the focus on three primary morphological parameters of interest for the purposes of tracking channel change moving forward. They are the bank height ratio using a constant As-built bankfull area and the cross sectional area and max depth based on each years low top of bank. These are calculated as follows: -Bank Height Ratio(BHR)takes the As-built bankful area as the basis for adjusting each subsequent years bankfull elevation. For example if the As-built bankfull area was 10 ft2,then the MY1 bankfull elevation would be adjusted until the calculated bankfull area within the MY1 cross section survey=10 ft2. The BHR would then be calculated with the difference between the low top of bank(LTOB)elevation for MY1 and the thalweg elevation for MY1 in the numerator with the difference between the MY1 bankfull elevation and the MY1 thalweg elevation in the denominator. This same process is then carried out in each successive year. z -LTOB Area and Max depth-These are based on the LTOB elevation for each years survey(The same elevation used for the LTOB in the BHR calculation). Area below the LTOB elevation will be used and tracked for each year as above. The difference between the LTOB elevation and the thalweg elevation(same as in the BHR calculation)will be recroded and tracked above as LTOB max depth. Note:The smaller the channel the closer the survey measurements are to their limit of reliable detection,therefore inter-annual variation in morphological measurement(as a percentage)is by default magnified as channel size decereases. Some of the variability above is the result of this factor and some is due to the large amount of depositional sediments observed.

When the sites are planted,hundreds of bare-root stems that essentially look like sticks are mixed by hand into sacks so that workers can grab a stem out of the sack,use a dibble bar to open a hole in the ground and plant a bare root,take a couple step and repeat. Identifying which species a tree/shrub is when they essentially look like sticks poking out of the ground can be very difficult and inaccurate which is why we decided to wait until MY1 to identify the species accurately. Please let me know if you have any more questions.

Thanks for the response,Jake.I do have two questions: 1.Will you please verify that the new alignment did not impact the existing wetlands that were around UT1A-1? 2.Since this is the as-built,shouldn't you know which species of trees are in each plot since they were just planted?

Good morning, Please see the responses below to Erin's questions. Please let me know if you need any additional information. DWR Comments,Erin Davis: Given the realignment change for UT1A-1,was the proposed vegetative swale feature also constructed in a new location? The original proposed alignment was incorrect due to survey error. The original alignment did not connect to the low valley point and hydrology source. The realignment was needed to connect to the the existing swale and source of hydrology above UT1A-1. This existing swale impounds some water and is vegetated and buffered by woody vegetation. It was determined during construction that clearing the woody vegetation to grade and plant herbaceous vegetation would create less functional improvement than leaving this feature as is. Since the vegetative survey was completed in May(growing season),why weren't the stem species identified in the veg plots table? Very young bare-root tree species are quite difficult to identify,regardless if they are beginning to bud and leaf out. Making guesses of species of individual stems during MYO when it is unclear,can create unnecessary work and confusion during subsequent monitoring reports by having to change and update tables and counts possibly leading to inaccuracies. All trees will be accurately identified by species during monitoring efforts this fall.
