General: The 2018 credit release meeting was held on April 24, 2018. Invasives on the site; beaver and beaver dams on the site; and encroachment on the site were discussed. RES indicated that all of the issues reported in the 2017 monitoring report (MY3) were resolved in early 2018 (March). The IRT requested a memo from RES to document the resolutions discussed. The IRT agreed to release the credits on the site as proposed upon approval of the 601 East memo. The requested memo was submitted to the IRT as requested and is included as Appendix F in the MY4 (2018) report. The IRT made a credit release site visit on July 12, 2018. Please document the IRT credit release site visit in the revised MY4 report. Any IRT comments, questions or concerns should be included in the meeting minutes. Meeting minutes can be included briefly in the report text or as a report Appendix in the final MY4 report. The IRT decided to forgo the July 12, 2018 site visit therefore there are no meeting minutes. General: Conservation Easement encroachment has been an issue on the 601 East site since MY1 (2015). DMS understands that the encroachment areas were remarked and replanted in March 2018. In the revised report, please confirm that encroachment has been eliminated based on RES's November 2018 site visit and monitoring data collection. If encroachment has not been eliminated, please discuss areas, issues and proposed resolutions in the revised MY4 report. As of November 2018, the encroachment has been eliminated. This has been added to Section 1.4.1. Section 1.4 — Project Performance: The NCDMS website for the project document portal should be updated to: https://deq.nc.gov/about/divisions/mitigation-services/dms-projects Done. Section 1.4.1 — Vegetation: The aquatic invasive "Parrot Feather" was a point of discussion during the July 12, 2018 IRT site visit. The May 3, 2018 adaptive management memo states that invasive treatment results will be described in the MY4 report. Please describe MY4 treatment efforts and results for the invasive species reported on the site and discuss proposed MY5 (2019) invasive treatment efforts. res.us 0 RES used an aquatic safe herbicide to the treat the Parrot Feather in the spring and fall of 2018. The Parrot Feather was still present in the areas noted on the CCPV during the November 2018 site visit. RES will reevaluate the efficacy of the aquatic herbicide in early 2019 and continue to treat the Parrot Feather if determined to be necessary. This has been added to the report. Section 1.4.2 — Stream Geomorphology: Please note that beaver should be trapped, and the associated dams removed from the project site for the entirety of the monitoring term. This should be completed as quickly as possible to avoid project damage and abnormal monitoring data. Beaver management, including trapping and dam removal, will be performed again in MY5. This has been added to the report. Were any dry channels observed on the site in the MY4 monitoring period on Reach 1 or Reach 2? Please update the text accordingly as this has been a previous DMS project concern. RES made site visits in March and November 2018. Dry channels on Reach 1 or Reach 2 were not observed during either site visit. Photo documentation from November 2018 is in Appendix B. This has been added to the report. Section 1.4.3 — Stream Hydrology: The report indicates that MY4 (2018) bankfull events were documented via wrack lines and only one event was noted at each location. Please confirm that the two (2) crest gauges installed on the site are functioning properly and have been maintained. Based on the precipitation data it appears likely that the site had more than 1 bankfull event in 2018. If the installed crest gauges are not capturing accurate yearly bankfull events, DMS recommends installing self -recording transducers. Both crest gauges were overrun with ants in MY4. RES cleaned the crest gauges out and expects them to record bankfull events in MY5. CCPV Sheets/ Report Text: In the report text, please describe/ discuss the erosional feature shown on Figure 2b (Reach 1). The erosional feature is a small headcut that formed at the edge of the easement from a field drain. The feature has stabilized with the maturation of vegetation in the buffer. If conditions worsen, RES will stabilize the headcut with rock and add coir logs along the feature. This has been added to the report. Table 2: Please list all invasive -exotic treatments, supplemental plantings, maintenance activities and beaver removal efforts in Table 2. The table should report all efforts post construction. Done. Table 13: Two (2) of the table entries in Year 3 have " * "; however, there are no footnotes included. Please include the footnotes. In the report text (or the missing footnote), please describe the difference in measurements for XS -17 between Year 2, Year 3 and Year 4. In MY3, the beaver dam directly downstream caused unusually high water and localized bank erosion. This footnote has been added back to Table 13. Electronic Deliverables: Please provide ALL project GIS shapefiles (stream layer, TOB, etc.) in the FINAL MY4 electronic deliverable CD. 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 over time 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). 601 East Stream Restoration Project 5 RES NCDMS Project No. 95756 Annual Monitoring Report Monitoring Year 4 of 7 January 2019 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 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 4 of 7 January 2019 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 0304010508 10 10 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 4 (MY4) data was collected in November 2018. Monitoring activities included visual assessment of all reaches and the surrounding easement, 20 permanent photo stations, nine pebble counts, and nine bankpin arrays. Per the Approved Mitigation Plan, vegetation and cross-section monitoring was not performed in MY4. 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 (https:Hdeq.nc.gov/about/divisions/mitigation-services/dms-projects). 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. The bare areas and encroachment areas that were lacking vegetation were addressed in March 2018. 250 container trees were planted in these areas and the encroachment on Reach 3 and 4 was blocked off by t -posts. Additionally, the Chinese Privet and Parrot Feather areas were treated in the spring and fall of 2018. RES used an aquatic safe herbicide to treat the Parrot Feather. As of November 2018, it was still present in the areas noted on Figure 2. RES will reevaluate the efficacy of the aquatic herbicide in early 2019. These areas will continue to be monitored and treated as necessary. Per the November 2018 site visit, the encroachment has been eliminated. A memo from May 2018 that describes the Adaptive Management in more detail is attached in Appendix F. Monitoring of the 10 permanent vegetation plots was not completed in MY4. The vegetation plots will be monitored again in MY5 and MY7. 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 that formed at the edge of the easement from a field drain. The feature has stabilized with the maturation of vegetation in the buffer. If conditions worsen, RES will stabilize the headcut with rock and add coir logs along the feature. The major stream problem areas from MY3 were two beaver dams on Reach 4. These dams and beavers were removed in March 2018 and the dams were completely taken out and the banks were stabilized and replanted. The beavers, however, returned in MY4 and built new dams on Reach 4. Beaver management, including trapping and dam removal, will be performed again in MY5. Geomorphic data was not collected in MY4 and will be collected again in MY5 and MY7. Substrate monitoring was performed during MY4. Pebble count D50 was fine gravel for Reach 1, fine gravel for Reach 2, coarse gravel for Reach 3, and medium 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 4 of 7 January 2019 1.4.3. Stream Hydrology During MY4 bankfull events were documented on both the Reach 2 and Reach 3 via wrack lines (Table 14; Figure 7). Project site precipitation data can be found in Table 15. Dry channels were not observed in MY4 during either site visit in March and November 2018. Photo documentation of the stream from November 2018 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, MY5, 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, MY2, MY3, MY5, MY7) is being monitored using 10 permanent monitoring plots. Vegetation monitoring followed CVS-EEP Level 1 Protocol for MY1 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 4 of 7 January 2019 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.

Encroachment areas near Reach 3 and 4 RES addressed the encroachment areas on Reach 3 and 4. The work included adding posts and tape to block off the encroachment area as well as repairing the appropriate crossing outside of the easement near VP5. RES also found another encroachment area on Reach 4 during a site visit in early 2018. This area is near the end of the project and was remarked with additional posts. Both impacted areas were replanted with about 200 three -gallon container trees. 2. Beaver dams on Reach 4 RES removed the beaver dams on Reach 4. The dams were completely taken out and the banks were stabilized with seed, straw, and livestakes. 3. Invasive species RES treated the invasive species on site. The treatment included the Parrot Feather on Reach 2 and the Chinese Privet on Reach 4. The Parrot Feather was treated with an aquatic herbicide as an experiment and the results will be reported at the end of MY4. Cattails were not treated because populations are isolated and are not negatively affecting the growth of planted trees. 4. Bare area on Reach 1 RES replanted about 50 three -gallon container trees in the 0.05 -acre bare area on Reach 1. Attached are photos and maps associated with the activities described above. Invasive species treatment will continue throughout the monitoring period as needed and RES will continue to keep a close watch on possible encroachment and beaver issues.
