III UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 DECEMBER 2016, MONITORING YEAR 2 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 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 the winter of 2015/2016, there were a number of high flow events. At least one of those inundated the floodplain, depositing woody debris and other flotsam in wrack lines well away from the top of bank. This flooding caused a number of channel and structure issues that are presented in the CCPV, tables and photos included with the e -file. These were all repaired in March of 2016 and functioned well through the summer with no further problems. Year 2 (MY2) monitoring indicated that the planted acreage was functioning well with no bank, bench or flood plain areas having bare areas of a significant size. The only invasive vegetation with significant coverage was Chinese privet, which was located in the existing forested area on the right bank MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 DECEMBER 2016, MONITORING YEAR 2 OF 5 of Silver Creek, downstream of the confluence with UT2. We will continue to treat privet within this area with herbicide to minimize the population. We continue to have a minor issue with mowing encroachments. Most of the sites where mowing encroachments occurred last year were avoided this year; however, we still have some mowing affecting the easement and will mark these areas to limit mowing access. We have established and are monitoring fourteen (14) vegetation plots at this site. The average density of total planted stems following the MY2 growing season is 740 stems per acre (n=14), with an additional average 43 volunteer stems per acre. Based on the average density of 740 stems per acre, the Site is on track to meet the established success criteria. Stream geomorphological stability and performance during MY2 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 MY2. 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 and on the three UTs had stabilized at sizes similar to what was seen last year. This indicates a properly functioning system, as there were no mid -channel bars or other sediment transport issues. Wetland monitoring during MY2 demonstrated that three of the thirteen 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 (USAW5, USAW7 and USAW13) demonstrated consecutive hydroperiods of 12 percent or greater, ranging from 26.7 to 37.3 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 2.4 percent to 6.5 percent of the growing season. Rainfall near the project (Morganton, NC) was determined to be at or below the 30th percentile for six of the twelve months of the year. The last half of September, October, and November, were almost completely dry at all four monitoring sites and Burke County was classified as being in a Severe Drought throughout November (NC Drought Management Advisory Council). Therefore, 2016 is considered to be below the normal precipitation range 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 A. The Year 2 monitoring data were collected in October and November 2016. Site photographic data was collected in August 2016. MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 DECEMBER 2016, MONITORING YEAR 2 OF 5 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 2 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 2 growing season was 740 stems per acre (n=14). There were also an average of 43 volunteer stems per acre, composed of seven different tree species. With an average density of 740 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. There was only one Vegetation Problem Area observed during MY2 and it is associated with the invasive species Chinese privet, Ligustrum sinense. Our observations indicated that the area of primary infestation by this species was the floodplain along the right bank of Silver Creek, downstream of the confluence with UT2. To control this invasive species, this area will be treated in 2017 during the appropriate treatment window. We identified four Mowing Encroachment Areas. There were two areas along the easement line where the landowner encroached into the easement while attempting to mow outside of the easement line. We think this occurred because he is mowing with a 15 foot wide bush -hog and it crosses the line in a couple of spots were trees (outside the easement) limit its movement. Encroachment in two other areas indicate that the landowner did not understand where the line was located. These areas will be pointed out to the landowner and the easement line at all encroachment areas will be better marked with witness posts before the landowner needs to mow again. No other areas of concern regarding the existing vegetation was observed along Silver Creek or the tributaries. Year 2 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. 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. 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 MY2 survey. Morphological survey data is presented in Appendix D. MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 DECEMBER 2016, MONITORING YEAR 2 OF 5 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 MY2 was assessed by surveying sixteen (16) cross-sections (7 on Silver Creek, 2 on UT1, 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 prevailing severe to extreme drought conditions that existed during the 4 to 5 months preceding our survey. 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 and performing at 100 percent for all parameters on all reaches. Flooding at this site during MY2, as described below, caused bank scour (8 locations) and damage to structures (5 locations) at the site. The locations, descriptions and photos of this damage are included in the Stream Problem Areas Table on the MY2 data electronic file. These sites were repaired in March 2016 and have functioned well during the rest of MY2. Overall, channel morphology is responding as designed and meeting project goals. Pebble count data for MY2 indicates that the shift to smaller particles on Silver Creek and on the three UTs has stabilized at sizes similar to what was seen last year. This indicates that smaller native bed material is being transported into project reaches and has shifted pebble size classes away from the constructed riffle particle sizes, seen in the As -built data. This indicates a properly functioning system, as there were no mid -channel bars or other sediment transport issues. 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 15 inches and 5 inches above bankfull, respectively. Physical indicators of bankfull flows, such as wrack lines and debris on the bank, were observed throughout the reach. We present at least five possible high water events, which could have caused the high flow recorded on project site crest gauges and shown in Table 9, the bankfull verification information. The most significant flow recorded was on December 29, 2015 and this storm event most likely caused valley wide flooding and the evidence of flooding that we observed in February. 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. MICHAEL BAKER ENGINEERING, INC. UPPER SILVER CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 94645 DECEMBER 2016, MONITORING YEAR 2 OF 5 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 USACE protocols (USACE 1997). Groundwater data collected during Year 2 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 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 MY2 demonstrated that three of the thirteen 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 (USAW5, USAW7 and USAW 13) demonstrated consecutive hydroperiods of 12 percent or greater, these ranged from 26.7 to 37.3 percent of the growing season. The gauges that did not meet success criteria (USAW1, USAW2, USAW3, USAW4, USAW6, USAW8, USAW9, USAW 10, USAW 11, and USAW 12) demonstrated consecutive hydroperiods of 12 percent or less, with a range from 2.4 percent to 6.5 percent of the growing season. The rain data for the region (Figure 8) shows that rainfall throughout the year was, at times, well below average. Baker will continue to monitor the groundwater hydrology of the Site during Monitoring Year 3. To evaluate annual rainfall in the project vicinity we utilized four USGS data recording stations that are within close proximity (11.3 to 15.7 miles from the site) to the project site. The CHRONOS stations that were used in the previous report had recorded several gaps in the data, and two were offline at the time this report was developed. The data from these stations was not sufficient to use in this yearly analysis of rainfall for the county, so the USGS stations were used instead. These data indicate that 2016 was relatively dry through winter, spring and summer with the exception of April and August, which were both above normal. Many of the months, especially later in the year, were exceptionally dry and were well below the 30th percentile. Rainfall near the project (Morganton, NC) was determined to be at or below the 30th percentile for six of the twelve months of the year. The last half of September, October, and November, were almost completely dry at all four monitoring sites and the region was classified as being in an Extreme Drought. Therefore, 2016 is considered to be below the normal range 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. 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 2 of wetland monitoring, ten of thirteen wells did not exhibit a hyrdroperiod of 12% or greater during the growing season. These wells will be observed closely throughout monitoring Year 3. 12 In-Situ groundwater monitoring dataloggers (1-12) 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.
