I have addressed the comments that you submitted on the draft report. My responses to your comments are the following: General • Wetland success has improved since MY2 and appears to be trending toward success. As a result, Task 9 will be paid in full. Please be aware that future task payments may be reduced if wetland gauges do not show signs of trending toward success and associated credits are deemed at risk. o Comment is noted. We will continue to monitor the wetland gauges throughout the winter and MY4 and record any changes in wetland performance. Table 2 • Please add June 2017 invasive treatment to table. o Invasive treatment was added to Table 2. • Please add July 2017 beaver dam removal to table o Beaver dam removal was added to Table 2. 797 Haywood Roadl Suite 2011 Asheville NC 28806 oma kasEMaN j�'SALLYPORT MBAKERINTL.CDM Off ice: 828.350.14o8IFax: 828.350.1409 CCPV or Figure 3 Table 5 Innovation Done Right ... We Make a Difference Modify either CCPV to show wetland components (R, E, Creation, riparian/non- riparian) or add well locations to Figure 3. The locations of the wells in relation to wetland component is valuable information for agency reviewers. o Both the CCPV and Figure 3 were modified to show both the wetland components and well locations on the site. This will make it easier to draw comparisons between the two maps in the future. Draft hard copy was missing Table 5, but it was in the PDF. Please QA/QC finals hard copies before submittal for completeness. o Table 5 was added to the hard copy of the report. Vegetation Plot Photos • Currently labeled as Figure 3 in hard copy. Should be Figure 4 according to Table of Contents. It is correctly labeled in PDF. o The Vegetation Plot Photos have been labeled Figure 4 in the report as well as the Table of Contents. Cross-sections • Cross-section 7 does not have MY3 data overlaid on graph. Please update and verify morphology data is correct on graph and corresponding tables. o MY3 data was added to Cross-section 7. Morphology data was correct on graph and corresponding tables. Profile Table 11 The UT2 profile and sections of UT3 indicates significant aggradation. As Baker is aware, the USACE will be looking at defined bed/bank and often denies credit for channels that have become filled with sediment. I am aware of the large upstream sediment sources from past mining activities on UT2. Does Baker have any corrective action or adaptive management planned for these. o No corrective actions are planned for the upcoming year. These sections of UT2 and UT3 will be monitored throughout the winter to see if high seasonal flows clear any of the deposited sediment from the channels and reevaluated in MY4. Consider increasing the significant digits on the Bank Height Ratio to two places. The BHR are shown this way on the cross-section plots (ex: XS1-1.06). This will help alleviate any problems with the IRT regarding calculating BHR and having "1.0" across the board. The IRT does not like to see 1.0 for BHR for every monitoring year. The IRT would like to see this number calculated for each monitoring year. o The significant digits on all Bank Height Ratios has been increased to two places on Tables 10 and 11. These will be presented this way going forward. Innovation Done Right ... We Make a Difference Table 12a Please double check the last column of data (Number of Instances where Water Table is 12 Inches from Ground Surface). I am unable to determine how the numbers shown are calculated when looking at the graphs. Consider removing this table from the report and just including in electronic deliverables. If you decide to remove from report, please update Table of Contents and Appendix E sheet. o The data in this column was still linked to earlier versions of the spreadsheet and had not updated. This has been corrected and the numbers now reflect data from MY3. This table was removed from the hard copy of the report but included in the electronic deliverables. The Table of Contents has been updated. If you have any questions or find any issues that need to be addressed, please contact me directly at (828) 412-6100. I am submitting an invoice for this task to Ms. Debby Davis in the Raleigh DMS Office and will be providing you an email copy.

III UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 NOVEMBER 2017, MONITORING YEAR 3 OF 5 1.0 EXECUTIVE SUMMARY Michael Baker Engineering, Inc. (Baker) restored or enhanced 5,186 linear feet (LF) of perennial stream channel along Silver Creek and three unnamed tributaries (UT 1, UT2, and UT3); and additionally restored, enhanced or created approximately 9.14 acres of wetlands that had been previously disturbed in Burke County, NC, (Appendix A). The Upper Silver Creek Stream and Wetland Restoration Project (Site) is located southeast of Morganton, NC, approximately 11 miles southeast of the intersection of Highway 64 and I-40 and to the north of the intersection of Highway 64 and Goldmine Road. The Site is located in the NC Division of Water Resources (NCDWR) sub -basin 03-08-31 and the NCDEQ Division of Mitigation Services (NCDMS) Targeted Local Watershed (TLW) 03050101-050050 of the Catawba River Basin. The project involved the restoration and enhancement of a Piedmont/Mountain Mixed Bottomland Hardwood Forest system (NC WAM 2010, Schafale and Weakley 1990) from impairments within the project area due to past agricultural conversion, cattle grazing, gold mining and draining of floodplain wetlands by ditching activities. The project goals directly addressed stressors identified in the Catawba River Basin Restoration Priority (RBRP) Plan such as degraded riparian conditions, channel modification, and excess sediment and nutrient inputs. The primary restoration goals, as outlined in the approved mitigation plan, are described below: • Create geomorphically stable stream channels within the Upper Silver Creek project area including headwater tributaries in the Catawba River basin; • Restore, enhance, and expand wetland functions across the Site; • Improve and restore hydrologic connections between streams and degraded riparian wetland areas and overall ecosystem functionality; • Improve water quality within the Upper Silver Creek project area through reduction of bank erosion, improved nutrient and sediment removal, and stabilization of streambanks; and • Improve aquatic and terrestrial habitat. To accomplish these goals, we recommended the following actions: • Restore the existing incised, eroding, and channelized stream by creating a stable channel that has access to its floodplain; • Improve water quality by establishing buffers for nutrient removal from runoff and by stabilizing stream banks to reduce bank erosion; • Improve in -stream habitat by providing a more diverse bedform with riffles and pools, creating deeper pools, developing areas that increase oxygenation, providing woody debris for habitat, and reducing bank erosion; and • Improve terrestrial habitat by planting riparian areas with native vegetation and protecting these areas with a permanent conservation easement. The riparian area will increase storm water runoff filtering capacity, improve bank stability, provide shading to decrease water temperature and improve habitat. During early 2017, there was at least one high flow event that inundated the floodplain, depositing woody debris and other flotsam in wrack lines well away from the top of bank. This event does not appear to have significantly impacted the bank repairs that were made after the flood event in 2015, although one of the repaired areas is beginning to show erosion and undercutting (CPA -3). Year 3 (MY3) monitoring indicated MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 NOVEMBER 2017, MONITORING YEAR 3 OF 5 that the planted acreage was functioning well with no bank, bench or flood plain areas having bare areas of a significant size. Invasive Chinese privet and multiflora rose were noted in the MY2 Monitoring Report as a problem, and were treated in June 2017. We will continue to treat invasive vegetation within this area with herbicide to minimize new growth. The areas of mowing encroachment noted in MY2 were marked with t -posts and flagged early in 2017, and there were no new mowing encroachments noted when MY3 monitoring was conducted. We have established and are monitoring fourteen (14) vegetation plots at this site. The average density of total planted stems following the MY3 growing season is 720 stems per acre, with an additional average of 64 volunteer stems per acre. Based on the average density of 720 planted stems per acre, the Site is on track to meet the established success criteria. Stream geomorphological stability and performance during MY3 was assessed by surveying sixteen cross- sections, a profile of each channel, evaluating the bed particle size with five riffle pebble counts and by replicating channel location photographs. Channel cross-sections and profiles were similar to what was observed in the past with no major instability identified and the general morphology is responding as designed and meeting project goals. At least one significant flood event that was greater than bankfull occurred during MY3. This storm event caused valley wide flooding with wrack lines well away from the top of stream banks. Stream pebble data indicated that the shift to smaller particles on Silver Creek main stem had stabilized at sizes similar to what was seen in previous years. Pebble counts on UT2 and UT3 indicate that fine sediment has accumulated in the channels since MY2. This is likely due to several factors. Backwater from Silver Creek during high water events inundates the location of the pebble count along UT2. It is likely that suspended fine sediment drops out of the water column in this backwater. Also, low flows early in the year allowed herbaceous vegetation to encroach into the channel and impede flow. This prevented fine particulates that entered from upstream of the project from moving through the system and eventually filled sections of the streambed with a layer of fine silt and clay. Lastly, all three pebble counts on the unnamed tributaries were taken in constructed riffles which were designed to be immobile. The constructed riffle material is designed to be much coarser than the natural sediment load than the stream receives. The natural, finer sediment load, is often then deposited on top of the constructed riffles, which shifts the bed material to a finer grain size distribution as compared to the as -built condition. Overall, these data indicate a properly functioning system, as there were no mid -channel bars or other sediment transport issues. Wetland monitoring during MY3 demonstrated that nine of the thirteen groundwater monitoring wells located on the Site met the wetland success criteria as stated in the Site Mitigation Plan (up from three of thirteen in MY2). The gauges that met success criteria (USAW1, USAW2, USAW5, USAW7, USAW8, USAW9, USAW10, USAW11, and USAW13) demonstrated consecutive hydroperiods of 12 percent or greater, ranging from 21.2 to 57.2 percent of the growing season. The gauges that did not meet success criteria demonstrated consecutive hydroperiods of 12 percent or less, with a range from 5.3 percent to 10.1 percent of the growing season. To rectify the wide range of rainfall data available from several nearby weather stations, a recording rain gauge was placed on-site and will be used in future monitoring years. Summary information/data related to the Site and statistics related to 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 and in the Mitigation Plan available on the NCDMS website. All raw data supporting the tables and figures in the appendices are available from NCDMS upon request. MICHAEL BAKER ENGINEERING, INC. 2 UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 NOVEMBER 2017, MONITORING YEAR 3 OF 5 2.0 METHODOLOGY The monitoring plan for the Site includes criteria to evaluate the success of the stream, wetland and vegetation components of the project. The methodology and report template used to evaluate these components adheres to the NCDMS monitoring guidance document dated December 1, 2009 and other mitigation guidance (NCDMS 2009 and USACE 2003), which will continue to serve as the template for subsequent monitoring years. The specific locations of monitoring features: vegetation plots, permanent cross-sections, monitoring wells, flow gauges, and the crest gauge, are shown on the CCPV sheets found in Appendix A. The Year 3 monitoring data and site photographs were collected in October 2017. 2.1 Vegetation Assessment In order to determine if vegetation success criteria are achieved, vegetation monitoring quadrants (veg plots) were installed and are monitored across the Site in accordance with the CVS-NCDMS Protocol for Recording Vegetation, Version 4.1 (CVS 2007 and Lee, Peet, Roberts and Wentworth 2007). The vegetation monitoring plots are a minimum of two percent of the planted portion of the Site with 14 plots established randomly within the planted riparian buffer and wetland area, per CVS Monitoring Level 2. No veg plots were established within the undisturbed wooded areas along the right bank of Silver Creek. The size of individual quadrants is 100 square meters for woody (tree) species and 1 square meter for herbaceous vegetation. Herbaceous quadrants were established in one corner of the larger woody plots and are monitored by comparing photographs taken year to year. Year 3 monitoring found that all vegetation was in good condition. All vegetation monitoring quadrants indicated that vegetation was growing and in good to excellent condition. The average density of planted stems following the Year 3 growing season was 720 stems per acre. There was also an average of 64 volunteer stems per acre, composed of six different tree species. With an average density of 720 planted stems per acre, the Site has met the minimum interim success criteria of 320 stems per acre by the end of Year 3, and is on track to meet the final success criteria of 260 stems per acre by the end of Year 5. The Vegetation Problem Area that was observed and noted in the MY2 monitoring report was addressed in Year 3. The Chinese privet found along the right floodplain of Silver Creek downstream of UT2 was treated during June 2017. All existing privet and new growth was treated with glyphosate in this area, and various other invasive vegetation was treated as necessary. Other target species included multiflora rose and Japanese honeysuckle. At the end of MY3, invasive vegetation growth is under control and will continue to be treated as necessary. The four previously identified mowing encroachment areas from MY2 were marked using t -posts, PVC pipe and flagging in March 2017 before the landowner began mowing. The easement boundary is now easy to see and avoid encroachment. At the end of MY3 no areas of encroachment have been noted. No other areas of concern regarding the vegetation were observed along Silver Creek or the tributaries. Year 3 vegetation assessment information is provided in Appendix C. 2.2 Stream Assessment The Upper Silver Creek Site approach is for restoration of a stable morphology that allows for the transport of water and sediment through the Site and allows stream flows larger than bankfull flows to spread onto the floodplain. Stream monitoring efforts focus on visual observations, a crest gauge to document bankfull flooding events, surveying established stream cross-sections and channel profiles to assess channel stability and pebble counts to assess if proper sediment transport is taking place. MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 NOVEMBER 2017, MONITORING YEAR 3 OF 5 Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy using Leica TS06 Total Station and was georeferenced to the NAD83 State Plane Coordinate System, FIPS3200 in US Survey Feet, which was derived from the As -built Survey. 2.2.1 Morphologic Parameters and Channel Stability Cross-sections were classified using the Rosgen Stream Classification System (Rosgen 1994) and all cross-sections were evaluated to determine if they meet design expectations. Cross-sections were also compared to the baseline cross-section plots to evaluate change between construction and the MY3 survey. Morphological survey data is presented in Appendix D. A longitudinal profile was surveyed for the entire length of each channel to document changes from the as -built baseline conditions during the first year of monitoring. The survey was tied to a permanent benchmark and measurements included thalweg, water surface, and top of low bank. Each of these measurements was taken at the head of each feature (e.g., riffle, pool) and at the maximum pool depth. Stream geomorphological stability and performance during MY3 was assessed by surveying sixteen (16) cross-sections (7 on Silver Creek, 2 on UT 1, 2 on UT2 and 5 on UT3) and a profile of these channels as described above. The bed particle size was evaluated with five riffle pebble counts (2 on Silver Creek and 1 on each of the tributaries) and by observation and replicating channel location photographs. Cross-sections of all the channels were very similar to past years especially at riffle cross-sections. Most pool cross-sections showed some level of deposition. This was likely due to low levels of flow during dry periods of the year. There was little change from past profile surveys and profiles of each channel do not indicate any instability issues. The Visual Morphological Stability Assessment indicates that the Site is stable with only minor CPAs identified. Two instances of piping were noted at two log vanes along the mainstem. These structures are called out in the CCPV as CPA -1 and CPA -2. There is also one instance of bank erosion and bank undercutting (CPA -3). The locations, descriptions and photos of this damage are included in the Stream Problem Areas Table in Appendix D and in the MY3 data electronic file. These sites will be monitored in the coming year and repaired if necessary. Overall, channel morphology is responding as designed and meeting project goals. Pebble count data for MY3 indicates that the shift to smaller particles on Silver Creek mainstem has stabilized at sizes similar to what was seen in previous years. Pebble counts on UT2 and UT3 indicate that fine sediment has accumulated in the channels since MY2. This is likely due to several factors. Backwater from Silver Creek during high water events inundates the location of the pebble count along UT2. It is likely that suspended fine sediment drops out of the water column in this backwater. Also, low flows early in the year allowed herbaceous vegetation to encroach into the channel and impede flow. This prevented fine particulates that entered from upstream of the project from moving through the system and eventually filled sections of the streambed with a layer of fine silt and clay. Lastly, all three pebble counts on the unnamed tributaries were taken in constructed riffles which were designed to be immobile. The constructed riffle material is designed to be much coarser than the natural sediment load than the stream receives. The natural, finer sediment load is often then deposited on top of the constructed riffles, which shifts the bed material to a finer grain size distribution as compared to the as -built condition. We will monitor these reaches to determine whether this problem resolves itself as the herbaceous vegetation dies back and high winter flows begin to move through the system. Overall, these data indicate a properly functioning system, as there were no mid -channel bars or other sediment transport issues. Two beaver dams were removed from the site during MY3 near the lower end of Reach 2 (Station 22+50 and Station 25+50). These dams backed up water in the stream, but do not appear to have MICHAEL BAKER ENGINEERING, INC. 4 UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 NOVEMBER 2017, MONITORING YEAR 3 OF 5 done permanent damage to streambanks or structure. Photos of the dams can be found in the Photolog. 2.2.2 Hydrology Two crest gauges were installed on the floodplain at this site, at the bankfull elevation. One is located along the left top of bank on Silver Creek, at approximately Station 19+00, and the second is on the left top of bank of UT3, at approximately Station 9+50. Crest gauges on Silver Creek and on UT3 recorded water levels of approximately .45 feet and .25 feet above bankfull, respectively. Physical indicators of bankfull flows, such as wrack lines and debris on the bank, were also observed throughout the reach. The event that occurred on 4/24/2017 was the highest flow recorded in the area, and likely caused the high flow recorded on project site crest gauges and shown in Table 9, the bankfull verification information. There was also a high flow recorded on 10/23/2017- 10/24/2017 that left debris piles and wrack lines above bankfull level throughout the site, but did not register on the crest gauge. Crest gauge readings are presented in Appendix D. 2.2.3 Photographic Documentation Reference transects were photographed at each permanent cross-section. The survey tape was centered in the photograph of the bank. The water line was located in the lower area of the frame, and as much of the bank as possible included in each photograph. Photographs were also taken at specific photo points established along each channel during baseline reporting. Photographs from these points will be replicated each year and used to document changes along the channel. Points were selected to include grade control structures as well as other structural components installed during construction. Annual photographs from the established photo points are shown in Appendix D and do not indicate any stability issues at the site and no failing structures. 2.3 Wetland Assessment Thirteen automated groundwater -monitoring stations were installed in the wetland restoration area to document the hydrologic conditions during the monitoring period. The installations followed USACE protocols (USACE 1997). Groundwater data collected during Year 3 monitoring are located in Appendix E. To meet the hydrologic success criteria, the monitoring gauge data must show that for each normal rainfall year within the monitoring period, the Site has been inundated or saturated for a certain hydroperiod. Criteria have been met when the wetland is saturated within 12 inches of the soil surface for 12 percent of the growing season when rainfall amounts approximate normal conditions. Alternatively, when dry conditions prevail, we may use the fourteen (14) or more consecutive days during the growing season when antecedent precipitation has been drier than normal for a minimum frequency of 5 years in 10 to 50 percent of the monitoring period (USACE, 1987 and 2005). Visual monitoring of wetland areas will be conducted annually. Photographs will be used to visually document system performance and identify areas of low stem density, invasive species vegetation, beaver activity, or other areas of concern. Reference stations will be photographed each year for a minimum of five years following construction. Photographs will be taken from a height of approximately five to six feet. Permanent well markers were established and used to ensure that the same locations (and view directions) on the Site are documented in each monitoring period. Wetland monitoring during MY3 demonstrated that nine of the thirteen groundwater monitoring wells located on the Site met the wetland success criteria as stated in the Site Mitigation Plan. Although four wells did not meet criteria, these data suggest a significant improvement in wetland performance since MY2. The gauges that met success criteria (USAW1, USAW2, USAW5, MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 NOVEMBER 2017, MONITORING YEAR 3 OF 5 USAW7, USAW8, USAW9, USAW 10, USAW 11, and USAW 13) demonstrated consecutive hydroperiods of 12 percent or greater, these ranged from 21.2 to 57.2 percent of the growing season. The gauges that did not meet success criteria (USAW3, USAW4, USAW6, and USAW12) demonstrated consecutive hydroperiods of 12 percent or less, with a range from 5.3 percent to 10.1 percent of the growing season. The rain data for the region (Figure 9) shows that rainfall in the early months of 2017 was at or below average. The early months of the growing season are generally when wetland water tables are highest on mitigation sites. This lack of early year rainfall may have contributed to the four unsuccessful gauges. Baker will continue to monitor the groundwater hydrology of the Site during Monitoring Year 4. An on-site recording rain gauge was installed at the site in August 2017. Data from this gauge will be used to measure local precipitation in the future to eliminate reliance on the nearby CRONOS stations. These stations often show a high level of variance across a small geographic area, which makes it difficult to determine the actual amount of rain the site receives. Having direct access to this data will allow accurate precipitation data to be collected and presented in future monitoring years. MICHAEL BAKER ENGINEERING, INC.
