Section 1.4.2: Please notify DMS when the erosional area has been fixed and the reported beaver dams have been removed. DMS recommends removing beaver dams as soon as possible to avoid potential project damage and additional maintenance. RES will notify DMS when these problem areas are repaired. Section 1.4.3: The report indicates that both crest gauges malfunctioned and no bankfull events were recorded in MY5. Although two (2) bankfull events have been recorded in separate years, please continue to repair equipment and document bankfull events for the remainder of the monitoring period. This section also reports dry channel above the crossing on Reach 1 during RES site visits in July and October 2019. RES should consider adding a stream flow gauge (pressure transducer) or a field camera to document at least 30 days of continuous flow on the intermittent portions of the reach. RES will add a flow gauge to the intermittent section of Reach 1 to document at least 30 days of continuous flow and replace the crest gauges with pressure transducers to avoid future maintenance. Table 6: The table reports 100% of all projects reaches visually assessed are stable and performing as intended. Please confirm that this is an accurate reflection of the MY5 project conditions. Even with the beaver dams and parrot feather in the channel, RES believes the project streams are stable and performing as intended. res.us Digital Support File and General Report Comments: 1. Please provide visual assessment excel tables. Done. 2. Please provide CVS entry tool data. Done. 3. CCPV needs to be segmented to match asset table and restoration types need to be symbolized in map and legend. Done. 4. Please provide segmented GIS to match comment 3. Segmented GIS is provided to the best of RES' ability. RES does not possess any CAD or GIS data from the mitigation plan/design (which the asset table is based off of). 5. XS Morphology Table - The direction of change in BHR calculations were correct using the fixed AB XSA method, but the magnitude appeared to differ in some cases from independent runs for a subset of riffle cross sections using a modified Mecklenburg spreadsheet (see attached). Please check. Alternatively, "<1" can be used if BHR is below 1. Calculation of XSA and Max depth are to be completed using TOB in keeping with methods specified in the Industry Technical Work group memorandum. Please include the Bankfull and LTOB elevations used in years 3 and 5. For clarity make sure the reader is aware that these methods are being employed. Include a footnote: "Bank Height Ratio is calculated based on the As -built (MYO) cross -sectional area as described in the Standard Measurement of the BHR Monitoring Parameter document provided by NCIRT and NCDMS (9/2018). The remainder of the bankfull dimensions are calculated based on the current year's low bank height." Done.

Goals and Objectives The project goals address stressors identified in the TLW and include the following: • Reduce water quality stressors originating in and around the project area affecting the project • reaches and downstream watercourses, which include population of the Savannah Lilliput • (Toxolasma pullus) and the Carolina Creekshell (Vilosa vaughiana), both listed species of concern. Specifically involving: o Reducing turbidity and sediment loading o Input reductions of nutrients and crop protection chemicals o Improving thermoregulation • Improving aquatic habitat quality and diversity within project reaches • Improving recruitment of instream fine organic matter (FOM) in the near term and both FOM and • large wood in the long term • Improving terrestrial habitat diversity and quality in the vicinity of project reaches • Establishing habitat continuity between the reach headwaters and Lanes Creek • Improving flood flow attenuation and floodplain interaction The project goals are addressed through the following project objectives: • Restore or enhance reach pattern, dimension, and profile • Stabilize eroding stream banks • Install stream structures to maintain grade and improve bed form complexity • Implement BMP detention devices on lateral agricultural drainages • Install diverse native riparian buffer • Removal of invasive exotic plant species • Secure a protective conservation easement and establish fencing as needed 1.2. Success Criteria The success criteria for the 601 East Stream Restoration Site follows accepted and approved success criteria presented in the USACE Stream Mitigation Guidelines and subsequent NCDMS and agency guidance. Specific success criteria components are presented below. 1.2.1. Stream Restoration Morphologic Parameters and Channel Stability — Restored and enhanced streams should demonstrate morphologic stability to be considered successful. Stability does not equate to an absence of change, but rather to sustainable rates of change or stable patterns of variation. Restored streams often demonstrate some level of initial adjustment in the period that follows construction and some subsequent change/variation is also to be expected. However, the observed change should not be unidirectional such that it represents a robust trend. If some trend is evident, it should be modest or indicate migration to another stable form. Annual variation is to be expected, but overtime this should demonstrate equilibrium on the reach scale with the maintenance of or even a reduction in the amplitude of variation. Lastly, all of this must be evaluated in the context of hydrologic events to which the system is exposed and the design type/intent (i.e. threshold versus free form alluvial channels). Dimension — General maintenance of a stable cross-section and hydrologic access to the floodplain features over the course of the monitoring period will generally represent success in dimensional stability. However, some change is natural and expected and can even indicate that the design was 601 East Stream Restoration Project 5 RES NCDMS Project No. 95756 Annual Monitoring Report Monitoring Year 5 of 7 January 2020 successful and appropriate for the hydrologic and sediment regime. Examples include depositional processes resulting in the development of constructive features on the banks and floodplain such as an inner berm, a slightly narrower channel, modest natural levees, and general floodplain deposition. For stream dimension, cross -sectional overlays and key parameters such as cross -sectional area, and the channel's width to depth ratios should demonstrate modest overall change and patterns of variation. Significant widening of the channel cross-section or trends of increase in the cross -sectional area generally represent concern, although some adjustment in this direction is acceptable if the process is arrested after a period of modest adjustment. In the case of riffle cross sections, maintenance of depths that represent small changes to target competence (e.g. consistently low BHRs <1.2) would also reflect stability. Although a pool cross-section may experience periodic infilling due to watershed activity and the timing of events relative to monitoring, the majority of pools within a project stream reach/component should demonstrate maintenance of greater depths and low water surface slopes over time. Rates of lateral migration need to be moderate. Bank pins will be installed to monitor rates of erosion. Pattern and Profile — Pool depths may vary from year to year, however the majority of pools should maintain depths that are distinct in the profile and are readily observed. Pattern measurement will not be collected unless observations indicate a detectable change based on observations and/or dimension measurements. Substrate — Generally it is anticipated that the bed materials will coarsen over time. The majority of riffle pebble counts should indicate maintenance or coarsening of the substrate. The D50 and D84 of the substrate should show a coarser distribution of bed materials in riffles and finer size class distribution in pools. Sediment Transport — Depositional features should be consistent with a stable stream that is effectively managing its sediment load. Point Bar and inner berm features should develop without excessive encroachment of the restored channel. Trends in the development of systemic robust mid - channel or alternating bar features will be considered a destabilizing condition and may require intervention. The tributaries outside of the conservation easement will be observed yearly and the monitoring report will document the function of the upstream basins in capturing excess sediment produced by observed degradation in the narrative. A specific performance standard has not been added. 1.2.2. Surface Water Hydrology Monitoring of stream water stages through a staff gauge should show recurrence of bankfull flow on average every 1 to 2 years. Throughout the monitoring period, the surface water stage should achieve bankfull or greater elevations at least twice. The bankfull events must occur during separate monitoring years. 601 East Stream Restoration Project 6 RES NCDMS Project No. 95756 Annual Monitoring Report Monitoring Year 5 of 7 January 2020 1.2.3. Vegetation The vegetation monitoring will be conducted according to the Carolina Vegetation Survey (CVS) — EEP protocol Version 4.2 (Lee et al 2008). Vegetation monitoring plots will be 100 square meters in size and will be conducted according to the Level I protocol which has a focus on planted stems only. The purpose of this level of monitoring is to determine the pattern of installation of plant material with respect to species, spacing, density, and to monitor the survival and growth of those installed species. The success criteria for the preferred species in the restoration areas will be based on annual and cumulative survival and growth over seven (7) years. Survival on preferred species must be at a minimum 320 stems/acre at the end of the three years of monitoring and 260 stems/acre after five years. At year 7, density must be no less than 210 seven -year -old planted stems/acre. Level II of the CVS protocol, which includes natural stems and planted stems, will be followed for the monitoring year 2 and subsequent years until the project close out year. 1.3. Project Setting and Background The 601 East Stream Restoration Site is located in Union County, approximately 13 miles south of Monroe, NC (Figure 1). The site encompasses 12.8 acres of formerly agricultural land and includes portions of Tanyard Branch, a tributary of Lanes Creek. The Site is located within the Yadkin River Basin, United States Geological Survey (USGS) 14-digit Hydrologic Unit 03040105081010 and the North Carolina Division of Water Resources (NCDWR) sub -basin 03-04-14. The drainage area of Tanyard Branch at the downstream end of the site is 0.56 square mile (354 acres). Land use within the watershed is predominately agriculture with the remaining land use composed of low density residential and forested areas. Following 2016 monitoring the NCIRT requested a review of the differential between the Approved Mitigation Plan and Baseline Monitoring Report. The table below details the discrepancies by reach. The primary cause of increased baseline SMUs is survey methodology (thalweg vs. centerline). The Mitigation Plan lengths were based on centerline. Additionally, there were likely minor field adjustments during construction.

Project Performance Monitoring Year 5 (MY5) data was collected in July and October 2019. Monitoring activities included visual assessment of all reaches and the surrounding easement, 10 vegetation plots, 18 cross sections, 20 permanent photo stations, nine pebble counts, and nine bankpin arrays. Summary information and data related to the occurrence of items such as beaver activity or encroachment and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report appendices. A visual overview of the site can be seen in the Current Conditions Plan View Maps (Figure 2). Photographs taken at permanent stations throughout the project site also display general site conditions (Figure 3). Narrative background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly Restoration Plan) documents available on the NCDMS website. All raw data supporting the tables and figures in the appendices is available from DMS upon request. 1.4.1. Vegetation Visual assessment of the easement (Table 5; Figure 2) indicates vegetation is well established throughout the easement. There was no encroachment observed in MY5. The parrotfeather areas were treated in 2018 and were still present in MY5 though some were dying back with the dry conditions observed in October. The areas of cattails are still present but only in localized wetland areas. Invasive areas will continue to be monitored and treated as necessary throughout the monitoring period. Monitoring of the 10 permanent vegetation plots was completed during October 2019. Summary tables and photographs associated with MY5 monitoring are located in Appendix C. Stem densities for MY5 ranged from 364 to 971 stems per acre with a mean of 607 stems per acre across all plots. When volunteer stems are included, the annual mean increases to 874 stems per acre. A total of 17 species were documented within the monitoring plots. The average planted stem height observed in the plots was 8.6 feet. 1.4.2. Stream Geomorphology Visual assessment of the stream was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation (Table 6). The erosional feature noted in the right buffer of Reach 1 is a headcut is in need of repair. RES will stabilize the headcut with rock and add coir logs along the feature. The major stream problem areas from MY5 were two beaver dams on Reach 4 and three beaver dams on Reach 2. These dams and beavers will be removed in 2020. Geomorphic data for MY5 was collected during July 2019. Summary tables and cross-section plots related to stream morphology are located in Appendix D. Baseline stream summary data for reference can be found in Table 10. Cross -sectional overlays showed minimal dimensional change between MY3 and MY5 data collection efforts (Table lla; Figure 6), as well as minimal change in overall reach dimensions (Table llb). None of the riffle cross sections exceeded a 1.2 BHR. Substrate monitoring was performed during MY5. Pebble count D50was medium gravel for Reach 1, coarse gravel for Reach 2, medium gravel for Reach 3, and coarse gravel for Reach 4 (Table 12; Charts 1-5). The channel substrate will be monitored in future years for shifts in particle size distributions. The bank pin arrays indicate that no erosion is taking place in the pools at cross -sections (Table 13). 601 East Stream Restoration Project 8 RES NCDMS Project No. 95756 Annual Monitoring Report Monitoring Year 5 of 7 January 2020 1.4.3. Stream Hydrology During MYS, no bankfull events were documented. Both crest gauges had become infested with ants and will be replaced in MY6. Project site precipitation data can be found in Table 15. No dry channels were observed in April but the reaches above the crossing on Reach 1 were dry in July and October. RES plans to add a flow gauge to the intermittent section of Reach 1 to document at least 30 days of consecutive flow. Photo documentation of the stream is in Appendix B. Summary information/data related to the performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly Restoration Plan) documents available on NCDMS' website. All raw data supporting the tables and figures in the appendices is available from NCDMS upon request. 2.0 METHODS Visual assessments of the project were performed at the beginning and end of the monitoring year. Permanent photo station photos were collected during vegetation monitoring. Additional photos of vegetation or stream problem areas were documented with photographs throughout the project area. Geomorphic measurements (MYO, MY I, MY2, MY3, MYS, MY7) were taken during low flow conditions using a Topcon GTS-312 Total Station. Three-dimensional coordinates associated with cross-section and profile data were collected in the field and geo-referenced (NAD83 State Plane feet FIPS 3200). Morphological data was limited to 18 cross -sections. Survey data was imported into CAD, ArcGIS, and Excel for data processing and analysis. Channel substrate was characterized using a Wolman Pebble Count as outlined in Harrelson et al. (1994) and processed using Microsoft Excel. Vegetation success (MYO, MY1, MY 2, MY 3, MY5, MY7) is being monitored using 10 permanent monitoring plots. Vegetation monitoring followed CVS-EEP Level 1 Protocol for MY and is following Level 2 Protocol Version 4.2 for monitoring years 2-7 (Lee et al. 2008). Level 2 Protocol includes analysis of species composition and density of planted species. Data is processed using the CVS data entry tool. In the field, the four corners of each plot were permanently marked with rebar and photos of each plot taken from the origin each monitoring year. The locations of the three temporary plots surveyed in Years 2 and 3 were randomly selected within the replant areas. The plots were surveyed by pulling tapes to form 10 x 10 meter plots then counting all woody stems within the plots. Precipitation data was reported from the NCCRONOS station number 315771 in Monroe, NC. Two crest gauges were installed on the mainstem channel, one upstream of Lansford Road in Reach 2 and another downstream of Lansford Road in Reach 3. During quarterly visits to the site, the height of the cork -line was recorded. 601 East Stream Restoration Project 9 RES NCDMS Project No. 95756 Annual Monitoring Report Monitoring Year 5 of 7 January 2020 3.0 REFERENCES Resource Environmental Solutions, LLC. 2015. 601 East Stream Restoration, Baseline Monitoring Document and As -Built Baseline Report Final, Union County, North Carolina.
