III UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 APRIL 2016, MONITORING YEAR 1 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 (UT1,UT2, and UT3); and additionally, Baker 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 1-40 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; • 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; • 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 Year 1, our monitoring indicated that the planted acreage was functioning well with no banks, benches or flood plain areas having bare areas of a significant size. The only invasive with significant coverage was Chinese privet, which was located in the existing forested area on the right bank of Silver Creek, both upstream and downstream of UT2. Chinese Privet within these areas will be treated with herbicide in the spring of 2016. An additional issue affecting Site vegetation was mowing encroachment. There were six areas along the easement line where the landowner encroached into the easement while attempting to mow outside of the easement line. These areas were pointed out to the landowner and we discussed the need to avoid encroaching MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 APRIL 2016, MONITORING YEAR 1 OF 5 into the easement. The easement line in these areas will be better marked with witness posts before the landowner needs to mow again. As noted in the Baseline report, we added five additional vegetation monitoring plots at the Site to increase the total from 9 to 14. The location of these new plots can be seen on Figures 2A and 213, designated 10 through 14. The average density of total planted stems following the Year 1 growing season is 804 stems per acre (n=14). There were no volunteer stems growing at this time. With an average density of 804 stems per acre, the Site is on track to meet the minimum interim success criteria of 320 stems per acre by the end of Year 3, and the final success criteria of 260 stems per acre by the end of Year 5. Stream geomorphological stability and performance during Year 1 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 each channel, evaluating the bed particle size with 5 riffle pebble counts and by observation and replicating channel location photographs. Cross-sections of all the channels indicated that high flows had deposited sediment on the floodplain and decreased cross-sectional area slightly. Deposition was also shown on the profiles of each channel and these indicate that some pools decreased in maximum depth. This observed deposition is not unusual during the first year as pool depth reaches an equilibrium with sediment supply and discharge. The Visual Morphological Stability Assessment indicates that the Site is stable and performing at 100 percent for all parameters on most reaches. We did find that on Reach 2 of Silver Creek, 3 of the 21 structures in this reach were piping water under a vane arm. These structures were repaired on August 27 & 28, 2015. Channel morphology is responding as designed and meeting project goals. There were no bankfull event recorded on the crest gauge during Year 1 and there was no physical indication of over bank flooding. Stream pebble count data indicated a shift to smaller particle sizes at XS7 on Silver Creek and on UT2. There was an increase in smaller particle sizes for the fraction less than D35 at XS8 of UT3, but the fraction D50 and above was similar to that estimated in the baseline data. Pebble data from XS4 on Silver Creek and on UT 1 showed particle sizes were either the same as baseline data or slightly larger. This indicates that the smaller particle sizes of the native bed material are being transported into, and through, the project reaches. This indicates a properly functioning system, as there were no mid -channel bars or other sediment transport issues. Wetland monitoring during Year 1 demonstrated that four of the twelve groundwater monitoring wells located on the Site met the wetland success criteria as stated in the Site Mitigation Plan. The gauges that met success criteria (USAW1, USAW5, MSAW7 and MSAW9) demonstrated consecutive hydroperiods of 12 percent or greater, these ranged from 17.1 to 38.7 percent of the growing season. The gauges that did not meet success criteria (USAW2, USAW3, USAW4, USAW6, USAW8, USAW10, USAW11 and USAW12) demonstrated consecutive hydroperiods of 12 percent or less, with a range from 1.2 percent to 10.5 percent of the growing season. Baker will continue to monitor the groundwater hydrology of the Site wetlands into Year 2. In December 2015, after an amendment to the Mitigation Plan was approved, one (1) additional well (USAW13) was installed in an area of jurisdictional wetland being enhanced, designated JDWla (See CCPV). This well was installed to document the groundwater level of this non -riparian wetland area. To evaluate annual rainfall in the project vicinity we utilized four CRONOS data recording stations that are within close proximity (11.5 to 17.4 miles from the site) to the project site. These stations were all different concerning the "Type of Station", which indicates a difference in data collection methodology. However, in spite of these differences the data collected were very similar and certainly indicate the same pattern in rainfall. These data indicate that 2015 was relatively dry through winter, spring and summer with the exception of April, which was normal or slightly above normal. September through December were exceptionally wet months with rainfall that far exceeded the historic 70`h percentile of average rainfall. According to the 2015 rainfall data, a large portion of the year experienced definitively lower than normal amounts of precipitation. Rainfall near the project was determined to be at or below the 30`h percentile for seven of the first eight months of the year (exception of April), through the month of August. Therefore, 2015 is considered to be below the normal range MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 APRIL 2016, MONITORING YEAR 1 OF 5 for the growing season. The dry conditions documented in this area are likely the reason that many of our gauges failed to meet the established success criteria. 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. 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 (NCEEP 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 B. The Year 1 monitoring data were collected between October and early December 2015. Site photographic data was collected in February 2016. 2.1 Vegetation Assessment In order to determine if 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 sizes of individual quadrants are 100 square meters for woody (tree) species and 1 meter for herbaceous vegetation. Herbaceous vegetation quadrants were established in one corner of the larger woody vegetation plots and are monitored by comparative photographs taken each year. The existing trees were visually monitored during the annual site visits to document any mortality, due to construction activities or changes to the water table, which could negatively impact existing forest cover or favorable buffer vegetation. Year 1 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 1 growing season is 804 stems per acre (n=14). There were no volunteer stems growing at this time. With an average density of 804 stems per acre, the Site is on track to meet the minimum interim success criteria of 320 stems per acre by the end of Year 3, and the final success criteria of 260 stems per acre by the end of Year 5. Invasive species areas of concern were observed and documented accordingly during Year 1. Monitoring indicated that there were two areas found to contain the invasive species, Chinese privet. To control this invasive species, these areas are scheduled to be treated in 2016 during the appropriate treatment window by use of the herbicide Glyphosate. There were six areas along the easement line where the landowner encroached into the easement while attempting to mow the area outside of the easement line. The easement line in these areas will be better marked with witness posts to make clear the line location. MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 APRIL 2016, MONITORING YEAR 1 OF 5 No other areas of concern regarding the existing vegetation was observed along Silver Creek, UTI, UT2 or UT3. Year 1 vegetation assessment information is provided in Appendix C. 2.2 Stream Assessment The Upper Silver Creek Site approach for the channels the 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. Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy using Leica TSO6 Total Station and was georeferenced to the NAD83 State Plane Coordinate System, FIPS32OO in US Survey Feet, which was derived from the As -built Survey. This survey system collects point data with an accuracy of less than one tenth of a foot. 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 MY1 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. 2.2.2 Hydrology Two crest gauge were installed on the floodplain at the bankfull elevation along the left top of bank on Silver Creek approximately at Station 19+00 and on the right bank of UT3 approximately at Station 9+50. No bankfull-flow events were recorded on the two Site crest gauges during the MYl data collection period, which primarily extended from April 1, 2015 to November 30, 2015. This is commonly a drier time of the year in this part of North Carolina, which was the case during 2015. 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. 2.3 Wetland Assessment Thirteen automated groundwater -monitoring stations were installed in the wetland restoration area in order to document the hydrologic conditions during the monitoring period. The installations followed MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 APRIL 2016, MONITORING YEAR 1 OF 5 USACE protocols (USACE 1997). Groundwater data collected during Year 1 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. Success criteria for wetland hydrology will be based on standards for atypical wetland areas (USACE, 2005). 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 mimic 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. 3.0 REFERENCES Carolina Vegetation Survey (CVS) and NC Ecosystem Enhancement Program (NCEEP). 2007.

Growing season for Burke County is from April 3 to October 29 and is 208 days long. Growing season percentage for success is 12% of 208 days = 25 days; where water table is 12 inches or less from the ground surface HIGHLIGHTED indicates wells that did not meet the success criteria for the most consecutive number of days within the monitored growing season with a water 12 inches or less from the soil surface. Following Year 1 wetland monitoring, eight of twelve wells did not exhibit a hyrdroperiod of 12% or greater during the growing season. These wells will be observed closely throughout monitoring Year 2. All In -Situ groundwater monitoring dataloggers were installed on 3/17/2015. Installation of the dataloggers was completed following construction in spring 2015 when groundwater levels are normally closer to the ground surface. Figure 10.
