Cover: Please include the USACE Permit Action ID and the DWR Project Number on the report cover page. Done. General: Encroachment has been an issue on the 601 East site since MY1 (2015). EBX/ RES indicated in both 2015 and 2016 that the encroachment would be eliminated by working with the landowner, installing additional signage, and providing an alternate tractor crossing. The encroachment on the site needs to be resolved in 2018. In the revised report, please document 2015-2017 efforts to resolve the encroachment. Please also provide a firm 2018 date for the installation of these additional measures on the project site. DMS property staff is willing to provide assistance enforcing the recorded conservation easement if requested. Done. General: As noted in the report text; 601 East is one of the projects that the IRT has requested be reverted to the Mitigation Plan asset totals prior to the 2018 credit release. Total stream assets will be reduced to 3,681.67 SMUs per the approved mitigation plan. Please note that the approved mitigation plan had a minor rounding error. The project will provide 3,638.67 Stream Mitigation Units (SMUs) (R) and 43 SMUs (RE). Please update and QA/QC the report accordingly. Contract 004925 stipulates a total of 3,576 SMUs so this update will not affect the current invoicing payment schedule. Section 1.2 — Success Criteria: The success criteria documented in the monitoring report should be the same (verbatim) as the success criteria in the IRT approved mitigation plan. Please update this section accordingly. Done. Section 1.4.1 - Vegetation: Invasive species were noted in the report verbiage and the CCPV mapping. In the report verbiage, please indicate if an invasive treatment is planned for the site in MY4 (2018). Cattails and Parrot Feather are reported on the site; will these species be treated res.us 0 during the remaining monitoring efforts? Please include this information and update the report text accordingly. The following was added to the report: RES does not plan to treat cattails and parrot feather this monitoring year nor in future monitoring years as long as the populations continue to decrease. RES believes as the riparian vegetation grows, the cattails and parrot feather will be shaded out. As reported in Table 7, please report the MY3 (2017) estimated average planted stem tree height observed (in feet) in the report verbiage. Done. 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 early as possible in MY4 (2018). Beavers were trapped in May 2017 and dams will be removed in early 2018. This has been added to the report. Were any dry channels observed on the site in the MY3 monitoring period on Reach 1 or Reach 2? Please update the text accordingly as this is a DMS project concern. The following was added to the report: According to notes and photos, both reaches had seasonal flow during MY3. Both reaches had flow in April, lower Reach 1 and Reach 2 had flow in July, but both were dry in November. Dry conditions in the fall can be attributed to drought conditions in the area. According to rainfall data in Monroe, between August and November this area received 9.22 inches of rain compared to the average of 16.48 inches. Section 2 Methods — Please briefly describe the methodology for selecting the three (3) random temporary vegetation plots and the associated data collection methods in this section. The methodology for selecting temporary vegetation plot location and data collection was added to this section. Table 1: Please revert Table 1 back to the totals found in the Mitigation Plan. Please note that the approved mitigation plan had a minor rounding error. The project will provide 3,638.67 Stream Mitigation Units (SMUs) (R) and 43 SMUs (RE) for a total of 3,681.67 SMUs. Add a note at bottom of the table to acknowledge communications with the IRT regarding the change. Suggested table note: ``* Stream credit calculations were originally calculated along the as -built thalweg. Based on the April 3, 2017 IRT Credit Release Meeting, these stream credits have been reverted back to the amounts in the IRT approved mitigation plan." Table 2: Please list all invasive -exotic treatments and supplemental plantings in Table 2. Please also remove the guidance notes below the table. The guidance has been removed and the table remains the same as no invasive -exotic treatments have occurred since construction and the only supplemental planting is listed. Cross Sections / Cross Section Tables — A couple of methods are currently being utilized to calculate the BHR from year to year. To compare subsequent monitoring years to the As -built condition one can hold the bankfull depth static (denominator) while allowing the Low TOB max depth (numerator) to vary. Another method that has been proposed and is being evaluated is to hold the As -built cross sectional area static within each year's new cross section and allow that to determine the max bankfull depth for each year. However; if there are large changes in the W/D ratio either method can make for somewhat distorted BHR values depending upon the 0 direction and magnitude of the change in the W/D ratio. Please update the calculations to reflect changes observed in the overlays and explain in detail as a table footnote how the calculations were made. Be prepared to defend the method used for the 2018 credit release and justify through context whether or not any changes observed in a cross section represent an issue. Starting in MY3, BHR was calculated on riffles using the baseline bankfull elevation. This method was used because the dimension of the channels has not changed enough to alter the bankfull elevation. None of the riffle cross sections exceeded a 1.2 BHR. This has been added to the text and to Table 11 a. Table 14: Please provide estimated dates for the bankfull events reported in the table and provide the data collection dates. Were the gauges checked three times during MY3 to determine that 3 bankfull events occurred at each reach? Done. Yes, the gauges were checked three times during MY3 showing three separate bankfull events on each gauge.

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 3 of 7 January 2018 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 crosssectional 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 3 of 7 January 2018 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 3 (MY3) data was collected from April to October 2017. Monitoring activities included visual assessment of all reaches and the surrounding easement, 20 permanent photo stations, 10 permanent vegetation monitoring plots, three temporary vegetation plots, 18 cross-sections, 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 (http://portal.ncdenr.org/web/eep). 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 that with the exception of a few bare areas, totaling 0.06 acres, vegetation is becoming well established throughout the easement. The number and size of the bare areas has decreased as the vegetation continues to establish. These areas will be monitored in subsequent site visits. Invasive populations have remained stable at the site. There are eight invasive species areas on site totaling 0.44 acres. The invasive species include Chinse privet (Ligustrum sinense), Parrot Feather (Myriophyllum aquaticum), and Cattails (Typha angustifolia). Japanese honeysuckle (Lonicera japonica) was also noted on site but is not considered a problem in MY3 as it is not hindering the growth of the trees. While no treatments were performed during MY3, treatment of these areas will be scheduled as needed in coming monitoring years. Easement encroachment was noted in two areas on Reach 3. The first area, near Vegetation Plot 5, appears as if a tractor has been cutting the corner continually forming a new road as well as herbicide spraying with some drifting into the easement and damaging the trees. The second area is at the end of Reach 3 where a thin strip has been cleared in between easement markers. Encroachment problem area photos can be found in Figure 4. RES plans to repair the crossing built near the first encroachment area so the farmer can access his fields without cutting through the easement. RES will be installing additional signage marking the easement boundary as well as replanting the affected areas. RES plans to have this work completed by the end of April 2018. Monitoring of the 10 permanent vegetation plots was completed during October 2017. Summary tables and photographs associated with MY3 monitoring are located in Appendix C (Table 7, 8 & 9; Figure 5). Stem densities for MY3 ranged from 405 to 1,012 stems per acre with a mean of 635 stems per acre across all plots. When volunteer stems are included, the annual mean increases to 919 stems per acre. A total of 17 species were documented within the monitoring plots. The average planted stem height observed in the plots was 141 cm (4.6 ft). Three temporary random plots were set up to monitor the effects of the re -planting, one on Reach 1 (Plot 1), Reach 2 (Plot 2), and Reach 3 (Plot 3). In each temporary plot, all of the woody stems located within the plot were counted to determine stem densities. Temporary plot 1 had 33 stems, temporary plot 2 had 23 stems, and temporary plot 3 had 47 stems which led to 1336, 931, and 1902 stems/acre, respectively in each plot. 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). Previously reported stream problem areas were visited again in MY3 and all are stable and no longer problems. The problems noted in MY3 include an erosion feature downcutting through the floodplain near Cross-section 8 and two beaver dams on 601 East Stream Restoration Project 8 RES NCDMS Project No. 95756 Annual Monitoring Report Monitoring Year 3 of 7 January 2018 Reach 4 (Figure 2; Figure 4). Beaver management was performed in May 2017 but did not include dam removal. The erosional feature needs livestakes and the beaver dams will be removed in early 2018. Geomorphic data for MY3 was collected during July 2017. 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 MY2 and MY3 data collection efforts (Table 11a; Figure 6), as well as minimal change in overall reach dimensions (Table 11b). Starting in MY3, BHR was calculated on riffles using the baseline bankfull elevation. This method was used because the dimension of the channels has not changed enough to alter the bankfull elevation. None of the riffle cross sections exceeded a 1.2 BHR. Substrate monitoring was performed during MY3. Pebble count D5o was coarse gravel for Reach 1, medium gravel for Reach 2, small cobble 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 with the exception the array at Cross-section 17. Field observations indicated that there was localized erosion around these two pins due to a beaver dam being built a few feet downstream and changing the hydrology in that area (Table 13). 1.4.3. Stream Hydrology During MY3 bankfull events were documented on both the Reach 2 and Reach 3 crest gauges (Table 14; Figure 7). Project site precipitation data can be found in Table 15 and Figure 8. 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 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 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 601 East Stream Restoration Project 9 RES NCDMS Project No. 95756 Annual Monitoring Report Monitoring Year 3 of 7 January 2018 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. 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.
