Monitoring Year 2 of 5 (2015) DMS Project Number 92633 December 2015 Cherokee County, North Carolina Table of Contents 1.0 PROJECT SUMMARY The North Carolina Department of Environmental Quality - Division of Mitigation Services (DMS) has established the Martin's Creek II Mitigation Project (Site) located in Cherokee County, just south of the town of Murphy. The Site includes a 93.87 -acre easement encompassed within 14 -digit Cataloging Unit 06020002170010 of the Hiwassee River Basin (Figure 1, Appendix B and Table 4, Appendix A). Land use at the Site, prior to mitigation activities, was composed of livestock pasture, open land, a residence, and forested areas. Martin's Creek and its tributaries were impaired by historical and current land management practices, which included timber harvesting, pasture, channelization, and livestock grazing. Completed project activities, reporting history, completion dates, project contacts, and project attributes are summarized in Tables 1-4 (Appendix A). The Site is located along Martin's Creek and several unnamed tributaries, which have been assigned Stream Index Number 1-49 and Best Usage Classification of C. Site streams are listed on the NCDWQ draft 2014 and final 2012 Section 303(d) list of impaired streams due to a fair bioclassification for reduced ecological/biological integrity and fish communities, and elevated levels of fecal coliform bacteria. The Site is located within a Targeted Local Watershed that has been identified for stream and buffer restoration opportunities (NCDMS 2008). The Site lies within the focus area of the Peachtree -Martins Creek Local Watershed Plan (LWP) and roughly corresponds to Restoration site #1 & Preservation site #1 of the LWP project atlas (NCDMS 2007). Goals of the LWP include implementation of wetland and stream restoration projects that reduce sources of sediment and nutrients by restoring riparian buffers, stabilizing stream banks, and restoring natural channel geomorphology, particularly in headwater streams. The project goals will directly address stressors identified in the Peachtree -Martins Creek LWP, namely lack of riparian vegetation, channel modification, excess sediment inputs, excess nutrient inputs, and bacterial contamination as follows. • Restore geomorphically stable stream channels within the Site; • Restore or enhance wetlands; • Exclude livestock from accessing project streams, wetlands, and riparian zones; • Improve and restore hydrologic connections and achieve uplift of ecosystem functions; • Improve water quality within the Site by reducing bank erosion, improving nutrient and sediment removal, and stabilizing stream banks; • Restore and preserve headwater tributaries to the Peachtree -Martins Creek Watershed and the Hiwassee River; and • Improve aquatic and terrestrial habitat by improving substrate and in -stream cover, adding woody debris, reducing water temperatures, and restoring riparian habitat. The Site mitigation plan was completed in March 2010 with the final design and construction plans completed in November 2010 (Table 2, Appendix A). Proj ect construction was completed between October 2012 and July 2013. The implemented mitigation is as follows (Figure 2, Appendix B and Table 1, Appendix A). Martin's Creek II (final) Axiom Environmental, Inc. Monitoring Year 2 of 5 (2015) DMS Project Number 92633 December 2015 Cherokee County, North Carolina page 1 8817 Stream Mitigation Units • Restoring approximately 3486 linear feet of stream channel through construction of stable channel at the historic floodplain elevation. • Enhancing (level I) approximately 832 linear feet of stream channel through cessation of current land use practices, installing grade control structures, repairing bank erosion, restoring proper channel dimension, and planting with native forest vegetation. • Enhancing (level II) approximately 1903 linear feet of stream channel through cessation of current land use practices, removing invasive species, and planting with native forest vegetation. • Preserving 21,327 linear feet of stream channel. 5.97 Riparian Wetland Mitigation Units • Restoring approximately 5.20 acres of riparian wetland by removing spoil castings, restoring stream inverts to historic elevations rehydrating stream -side wetlands, removing drain tile, eliminating land use practices, and planting with native forest vegetation. • Enhancing approximately 1.61 acres of riparian wetland by fencing livestock and supplemental planting. Planting a native woody riparian buffer (at least 30 feet in width) adjacent to restored/enhanced streams and wetlands within the Site. • Protecting the Site in perpetuity with a conservation easement. Stream Success Criteria Stream restoration success criteria for the Site are based on the Stream Mitigation Guidelines issued in April 2003 by the USACE and NCDWQ. Success criteria for stream restoration will include 1) documentation of two bankfull events, 2) little change in the channel cross-section from as -built conditions, 3) stable longitudinal profile, 4) substrate consistency, and 5) photographic evidence of stability. Bankfull Events Two bankfull flow events in separate years must be documented within the 5 -year monitoring period. Otherwise, the stream monitoring will continue until two bankfull events have been documented in separate years. Cross-sections Riffle cross-sections on restoration and enhancement reaches should be stable and should show little change in bankfull area, maximum depth ratio, and width -to -depth ratio. Riffle cross-sections should generally fall within the parameters defined for channels of the appropriate Rosgen stream type. If any changes do occur, these changes will be evaluated to assess whether the stream channel is showing signs of instability. Indicators of instability include a vertically incising thalweg or eroding channel banks. Changes in the channel that indicate a movement toward stability or enhanced habitat include a decrease in the width -to - depth ratio in meandering channels or an increase in pool depth. Lonizitudinal Profile Longitudinal profile data for the stream reach should show that bedform features are remaining stable. The riffles should be steeper and shallower than the pools, while the pools should be deep with flat water surface slopes. The relative percentage of riffles and pools should not change significantly from the design parameters. Bed Material Anal Substrate materials in restoration reaches should indicate a progression towards or the maintenance of coarser materials in the riffle features and smaller particles in the pool features. Martin's Creek II (final) Axiom Environmental, Inc. Monitoring Year 2 of 5 (2015) DMS Project Number 92633 December 2015 Cherokee County, North Carolina page 2 Photo Reference Sites Photographs will be used to evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures subjectively. Lateral photos should not indicate excessive erosion or continuing degradation of the banks. A series of photos over time should indicate successive maturation of riparian vegetation. Vegetation Success Criteria Success criteria have been established to verify that the vegetation component supports community elements necessary for forest development. Success criteria for this project includes an average density of 320 planted stems per acre must be surviving in the first three monitoring years. Subsequently, 290 planted stems per acre must be surviving in year 4, and 260 planted stems per acre in year 5. Wetland Success Criteria Hydrologic success will be based on conditions of on-site reference wetlands. Success will be determined by the following criteria. Years One Through Three Hydrologic success criteria will be met if the Site demonstrates groundwater table levels within 12 inches of the soil surface for a minimum of 13% of the growing season (this criterion reflects a deviation of 50% from the duration of saturation expected for this type of wetland system (-25%). Success for monitoring years one through three will be determined based on this 50% tolerance of deviation from the duration of wetland hydrology at the reference sites. Years Four and Five Success for monitoring years four and five will be determined based on a 20% tolerance of deviation from the duration of wetland hydrology at the reference sites. Therefore, it is expected that in years four and five the site will achieve a minimum of 20% saturation. Based on reference conditions and the criterion stated above, it is expected that reference soil saturation for years one through five will continue to exceed the regulatory 12.5% minimum requirement of the growing season for Cherokee County. In order to attain conditions suitable for the formation of wetland vegetation and hydric soils, the Site should be saturated within 12 inches of the surface or inundated for consecutive period equal to 24 days. However, to meet hydrologic success criteria and mimic the reference wetland hydrology, the site should demonstrate wetland hydrology for a minimum of 25 days in years one through three. In years four and five, this will increase to a minimum of 38 days. Overbank flooding from the adjacent channel will also be noted during monitoring. Reference areas will be monitored for a minimum of five years. Summary information/data related to the occurrence of items such as beaver or encroachment and statistics related to performance of various project and monitoring elements can be found in tables and figures within this report's 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 the Restoration Plan) documents available on the Division of Mitigation Services (DMS) website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. 2.0 METHODOLOGY Monitoring of the Site's restoration efforts will be performed until agreed upon success criteria are fulfilled. Monitoring is proposed for the stream channel, riparian vegetation, and hydrology for a period of five years (Figures 2 & 2A -2C, Appendix A). Monitoring reports of collected data will be submitted no later than December of each monitoring year. Martin's Creek II (final) Axiom Environmental, Inc. Monitoring Year 2 of 5 (2015) DMS Project Number 92633 December 2015 Cherokee County, North Carolina page 3 2.1 Streams Post -restoration monitoring will be conducted for five years following the completion of construction to evaluate the effectiveness of the restoration practices. Measurements were taken using a Topcon GTS 303 total station and Recon data collector. The raw total station file was processed using Carlson Survey Software into a Computer Aided Design (CAD) file. Coordinates were exported as a text/ASCII file to Microsoft Excel for processing and presentation of data, and are not georeferenced. Pebble counts were completed using the modified Wolman method (Rosgen 1993). Monitored stream parameters include stream dimension (cross-sections), pattern (longitudinal survey), profile (profile survey), and photographic documentation. Stream data can be found in Appendix D. Bankfull Events The occurrence of bankfull events within the monitoring period will be documented by the use of a crest gauge and photographs. One crest gauge was installed to record the highest watermark between site visits; the gauge will be checked each Site visit to determine if a bankfull event has occurred (Figure 2A, Appendix B). Photographs will be used to document the occurrence of debris lines and sediment deposition on the floodplain during monitoring site visits. Five bankfull events have been documented to date during monitoring year 2 (2015) for a total of eleven bankfull events during years 1 (2014) and 2 (2015). Cross-sections A total of 19 permanent cross-sections, 12 riffle and 7 pool, were established and will be used to evaluate stream dimension; locations are depicted on Figures 2, 2A, and 2B (Appendix B) Because riffle cross- sections are critical in determining bankfull design parameters, the number of riffle cross-sections established will generally outnumber pool cross-sections. Each cross-section will be marked on both banks with permanent pins to establish the exact transect used. A common benchmark will be used for cross- sections and consistently used to facilitate easy comparison of year-to-year data. The annual cross-section survey will include points measured at all breaks in slope, including top of bank, bankfull, inner berm, edge of water, and thalweg, if the features are present. Riffle cross-sections will be classified using the Rosgen Stream Classification System. No areas of concern or indicators of instability were observed during year 2 (2015) monitoring; therefore, stream dimension measurements are currently meeting success criteria. Longitudinal Profile After Site construction, approximately 4493 linear feet of longitudinal profile was completed to document baseline conditions. Longitudinal profile will be resurveyed annually for the duration of the five-year monitoring period. Measurements include thalweg, water surface, bankfull, and top of low bank. Each of these measurements will be taken at the head of each channel unit (e.g., riffle, pool) and at the maximum pool depth. The survey will be tied to a permanent benchmark. No areas of concern or indicators of bedform instability were observed during year 2 (2015) monitoring; therefore, stream longitudinal profile measurements are currently meeting success criteria. Bed Material Analysis Pebble counts will be conducted annually on one permanent riffle cross-section (100 -counts) at the time cross-section and longitudinal surveys are performed during the five year monitoring period. These samples will reveal changes in sediment gradation over time as the stream adjusts to upstream sediment loads. Year 2 (2015) pebble counts indicate the maintenance of coarser materials in the measured riffle feature; therefore, bed material is currently meeting success criteria. Martin's Creek II (final) Axiom Environmental, Inc. Monitoring Year 2 of 5 (2015) DMS Project Number 92633 December 2015 Cherokee County, North Carolina page 4 Photo Reference Sites A total of 26 photographs will be used to visually document restoration success for at least five years following construction. Photographs will be taken from a height of approximately five to six feet. Photo locations will be recorded using sub -meter GPS to ensure that the same locations (and view directions) on the Site are monitored in each monitoring period. Year 2 (2015) photo reference sites show no channel aggradation or degradation, or bank erosion. In addition, riparian vegetation is meeting success criteria based on stem counts across the Site; however, it is too early in the monitoring period to show successive maturation of riparian vegetation. 2.2 Vegetation After planting was completed, an initial evaluation was performed to verify planting methods were successful and to determine initial species composition and density. Fifteen sample vegetation plots (10 - meter by 10 -meter) were installed and measured within the Site as per guidelines established in CVS -DMS Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008). Vegetation plots are permanently monumented with 6 -foot metal t -posts at each corner. In each sample plot, vegetation parameters to be monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species will also be documented by photograph. Vegetation plot data can be found in Appendix C. Supplemental planting occurred at the Site in early 2015 with 3000 bare root stems as follows (Figures 2A - 2C (Appendix A). 500 river birch (Betula nigra) 500 sycamore (Platanus occidentalis) 500 tulip poplar (Liriodendron tulipifera) 500 black gum (Nyssa sylvatica) 500 northern red oak (Quercus rubra) 500 Shumard's oak (Quercus shumardii) 3000 Year 2 stem count measurements indicate an average of 459 planted stems per acre (excluding livestakes) across the Site; therefore, the Site is currently meeting vegetation success criteria. In addition, all fifteen individual vegetation plots met success criteria based on planted stems alone. 2.3 Wetland Hydrology Thirteen RDS Ecotone WM groundwater monitoring gauges were installed within Site wetland restoration areas to monitor groundwater hydrology (Figure 2A, Appendix A). Hydrological sampling will continue for five years with gauges recording daily and downloaded at a minimum of quarterly throughout the growing season (April 14 -October 21). In addition, an on-site rain gauge will document rainfall data for comparison of groundwater conditions with extended drought conditions. Finally, groundwater gauges located within riverine wetlands adjacent to restored stream reaches will supplement crest gauge measurements to confirm overbank flooding events. Twelve of the thirteen groundwater gauges met or exceeded wetland success criteria for the Year 2 (2015) monitoring year. Although it is too early in the monitoring period to determine the extent of wetland that is currently meeting wetland hydrology success criteria, Year 2 (2015) data indicates that the majority of the Site wetland area is successful.

This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the project effort. 2 = The acreage within the easement boundaries. 3 = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. 4 = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern/interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree/shrub stands over timeframes that are slightly longer (e.g. 1-2 decades). The low/moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by DMS such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not Ilkley trigger control because of the limited capacities to impact tree/shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in red italics are of particular interest given their extreme risk/threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or polygon/area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary.
