(AXE) is pleased to provide you with three hard copies and one cd of electronic files for the Final Neighbors Branch/ Walton Crawley Branch Year 2 (2017) Annual Monitoring Report. We received your comments via email on December 4, 2017 and have addressed them as follows. Wetland Hydrology: Report indicates that Gauge 1 malfunctioned during the growing season. Has the gauge been replaced or repaired? Please add a statement in this section stating the corrective action and that the gauge is functioning correctly. The wetland hydrology discussion was updated to read as follows: "Gauge 1 malfunctioned for 6 days (July 29 to August 3, 2017) during the growing season. It is unclear why the gauge was not taking measurements during this time, but it appeared to be functioning properly before and after the malfunction, and it was checked and reset at the time of the next data download. The gauge had no more issues for the remainder of the growing season. Based on precipitation data as well as data from Gauge 2, it is expected that this gauge would have continued to be saturated/inundated during this 6 day period. " • Table 2: Under Year 2 Monitoring, please add two lines of additional data with dates. One for vegetation monitoring and one for geomorphology monitoring. The IRT would like to know when data is being collected for the monitoring years. Please do this for all future monitoring report submissions. These rows were added to Table 2, and these will be added for all future monitoring report submissions. • Cross-sections and Table 11 a: Please calculate BHR for cross-sections. If the BHR has been calculated, please increase the significant digits to 3 places to account for rounding and to show small changes over the course of monitoring (Ex: 1.0 changed to 1.002 or similar). The bank height ratio was recalculated for all cross-sections, and since no cross-sections have exhibited any stream bed elevation change during the monitoring period, all cross-sections have a bank height ratio of]. 0. This indicates minimal geomorphic change and good cross-sectional stability across the site. • In the future, please use a date stamp on photos. The IRT has requested this be included with all photos. All Axiom staff have been notified to use a time -stamp on all future monitoring photos. • As Axiom had done in the past, please include a response to the comment letter and how/where the comments were addressed. Please insert this letter directly behind the cover page and before the table of contents in the final deliverables. The IRT has requested that we include this letter with the final deliverables. The response letter will need to be included with all future monitoring deliverables. This letter has been inserted into the report between the cover page and table of contents.

The primary goals of the project focused on improving water quality and long term stability by reducing nutrient loading from the on-site cattle and horse operation, reducing excess sedimentation input from Site channel banks and contributing non jurisdictional tributaries/drainages, reducing excess sedimentation from Site access roads and deteriorated crossings, increasing the attenuation of floodwater flows, reintroducing natural watershed flows to Walton Crawley Branch by removing a pond and restoring the channel through its natural valley, and restoring and enhancing aquatic and riparian habitat. Long term stability will be evidenced by channels maintaining stable inverts and banks over an extended period of time. These goals were accomplished through the following objectives. • Reduce point (i.e. cattle/horses directly accessing the channel) and non -point source (i.e. stormwater runoff through pastures) pollution associated with an on-site cattle and horse operation by installing exclusionary fencing along the stream and riparian buffer, and by providing a vegetative buffer on stream banks and adjacent floodplains to treat nutrient enriched surface runoff from adjacent pastureland. • Stabilize degraded portions of on-site streams, eroding ephemeral/stormwater channels, and existing maintained dirt roads to reduce sediment inputs. Stabilization methods included: o Restoring a stable dimension, pattern, and profile to selected sections of channels to ensure the channel will transport and attenuate watershed flows and sediment loads without aggrading or degrading. o Stabilize selected channel banks by excavating bankfull benches, placing stream structures to reduce shearing forces on outside meander bends, and planting native vegetative species to provide soil stability. o Stabilize ephemeral/stormwater channels by planting native vegetation along eroded banks and floodplain and constructing stabilization weirs through the channel valley to lower facet slopes and decrease erosion. o Place gravel along existing degraded soil roads that are situated adjacent to Site streams. • Reintroduce natural watershed flows to Walton Crawley Branch by restoring the channel through the low point of the natural valley and removing a dam that impedes natural down valley flows. • Improve aquatic habitat by enhancing stream bed variability, providing shading/covered areas within the stream channel, and introducing woody debris in the form of rootwads, log vanes, and log sills. • Enhance fish passage within Neighbors Branch and Walton Crawley Creek. This was accomplished by eliminating a pond and restoring the stream through the natural valley and by restoring Neighbors Branch and replacing an existing perched culvert to allow fish passage upstream. • Enhance riparian wildlife habitat by: o Fencing cattle out of existing wetlands and planting impacted wetlands with native vegetative species. Wetlands were also restored by raising Site stream inverts to allow groundwater tables to rise throughout the affected valleys. o Fencing livestock out of existing and restored riparian buffers as well as installing alternative watering devices that will ensure livestock have sufficient watering areas. This is detailed further in the Farm Management Plans completed for the Site by NCDMS. o Vegetating the existing fescue dominated riparian buffers with native trees, shrubs, herbs, and grasses. Forest vegetation species were selected by studying a Reference Forest Ecosystem located on-site and reviewing Montane Alluvial Forest species listed in Neighbors Branch/Walton Crawley Branch Monitoring Year 2 or 5 (2017) DMS Project No. 92872 December 2017 McDowell County, NC page 1 Classification of the Natural Communities of North Carolina: Third Approximation (Schafale and Weakley 1990). • Creating wildlife corridors through agricultural lands which have significantly dissected the landscape. The corridors will provide connectivity to a diversity of habitats including mature forest, early successional forest, stream -side forest, riparian wetlands, and uplands. The Site is located approximately six miles southeast of the town of Marion (Figure 1, Appendix B). The Site is situated due southwest of the intersection of Deer Park Road and Harmony Grove Road in McDowell County, North Carolina and is located within the United States Geological Survey (USGS) Hydrologic Unit and Targeted Local Watershed 03050101040010 (North Carolina Division of Water Quality Subbasin 03- 08-30) of the Catawba River Basin and will service USGS 8 -digit Cataloging Unit 03050101. The contributing watersheds are characterized primarily by forest land (approximately 84 percent of the total area) with pasture at the lower elevations (approximately 10 percent of the total area) and low-density residential development scattered along the outer fringes of the watershed. Impervious surfaces appear to account for approximately one percent of the watershed land surface. Prior to Site construction, riparian vegetation had been removed, stream channels were manipulated, and hoof shear from livestock on stream banks and floodplain soils was responsible for degraded water quality and unstable channel characteristics (stream entrenchment, erosion, and bank collapse). Project mitigation efforts resulted in the following: • Restore 2456 linear feet of Site streams • Enhance (Level I) 202 linear feet of Site streams • Enhance (Level II) 1863 linear feet of Site streams • Preserve 3139 linear feet of Site streams • Restore 0.52 acre of existing hydric soils to riparian wetlands • Enhance 1.62 acres of riparian wetlands • Preserve 1.29 acres of riparian wetlands The Muddy Creek Restoration Partnership (Partnership) was formed in 1998 to address impacts to the Muddy Creek Watershed. The Partnership completed the Muddy Creek Watershed Restoration Initiative Feasibility Report and Restoration Plan (Watershed Plan) for the Muddy Creek Watershed in December of 2003 (MCRP 2003). Since 2004 NCDMS has informally participated in the Partnership by implementing priority projects named by the partnership and adopted the 2003 report as part of its Local Watershed Plan (LWP). The NCDMS's Upper Catawba River Basin Restoration Priorities (2009) identifies North Muddy Creek as a Targeted Local Watershed (TLW). The Site is located within the North Muddy Creek Watershed. In 2008 NCDMS contracted with a consulting firm to conduct outreach programs with landowners and identify additional project sites in the Muddy Creek Watershed. The primary goals identified by the Partnership's Watershed Plan include the following. 1. Restore the Watershed to its Full Intended Use 2. Restore Riparian Buffers 3. Enhance Open Space Preservation 4. Improve Water Quality 5. Restore Physical Habitat 6. Establish a Trout Fishery The Watershed Plan listed the following components of watershed restoration to be expected: Neighbors Branch/Walton Crawley Branch Monitoring Year 2 or 5 (2017) DMS Project No. 92872 December 2017 McDowell County, NC page 2 1. Natural Channel Design Stream Restoration 2. Riparian Reforestation 3. Livestock Exclusion 4. Riparian Forest Preservation These four components were included within the Neighbors Branch/Walton Crawley Branch Site Mitigation Plan (NCDMS 2013). The project restored the watershed to its full intended use by restoring a stream, floodplain, and riparian wetland ecosystem through stream and wetland restoration, enhancement, and preservation. The project restored riparian buffers through revegetation of buffer zones with native riparian and wetland species along all Site streams. The project enhanced open space preservation by placing Site streams, wetlands, and their buffers into a permanent conservation easement. The overall Site helps improve water quality by reducing sedimentation in on -Site streams and planted a vegetated riparian buffer that filters nutrients from adjacent pasturelands. Additionally, exclusionary fencing and alternate watering devices removed livestock from accessing on-site channels and riparian buffers. The project restored and enhanced physical habitat for both aquatic and terrestrial species by planting native vegetation along stream banks and riparian buffers, creating wildlife corridors through a dissected landscape, and restoring bedform variability to Site streams. The stabilization of streams and buffers in the project area enhanced water quality in downstream receiving waters, which should help in the re-establishment of the watershed's ability to host trout and enhance their ability to propagate. Site design was completed on March 7, 2013. Site construction and planting were completed in December 2015. Completed project activities, reporting history, completion dates, project contacts, and project attributes are summarized in Tables 1-4 (Appendix A). Stream Success Criteria: Success criteria for stream restoration will include 1) successful classification of the reach as a functioning stream system (Rosgen 1996) and 2) channel variables indicative of a stable stream system. Collected data will be utilized to determine the success in restoring stream channel stability. Specifically, the width -to -depth ratio and bank -height ratios should be indicative of a stable or moderately unstable channel with minimal changes in cross-sectional area, channel width, and/or bank erosion along the monitoring reach. In addition, channel abandonment and/or shoot cutoffs must not occur and sinuosity values must remain relatively constant. Visual assessment of instream structures will be conducted to determine if failure has occurred. Failure of a structure may be indicated by collapse of the structure, undermining of the structure, abandonment of the channel around the structure, and/or stream flow beneath the structure. Stream 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. Some changes in dimension (such as lowering of bankfull width) should be expected. Riffle cross-sections should generally maintain a bank -height ratio approaching 1.0, with some variation in this ratio naturally occurring. Pool cross-sections naturally adjust based on recent flows and time between flows, therefore more leeway on pool cross-section geometry is expected. Stream Pattern and Profile: The profile should not demonstrate significant trends towards degradation or aggradation over a significant portion of a reach. Additionally, bed form variables should remain noticeably intact and consistent with original design parameters that were based off Neighbors Branch/Walton Crawley Branch Monitoring Year 2 or 5 (2017) DMS Project No. 92872 December 2017 McDowell County, NC page 3 of reference conditions. Pattern features should show little adjustment over the standard 5 -year monitoring period and will be monitored to ensure adjustment is minor prior to close out. Substrate: Substrate measurements should indicate the progression towards or the maintenance of the known distributions from the design phase. Sediment Transport: There should be an absence of any significant trend in the aggradational or depositional potential of the channel. Hydraulics: A minimum of two bankfull events must be documented within the standard 5 -year monitoring period. The two bankfull events shall occur within separate years. Vegetation Success Criteria: Success criteria have been established to verify that the vegetation component supports community elements necessary for forest development. Success criteria are dependent upon the density and growth of characteristic forest species. An average density of 320 stems per acre of planted stems 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 Hydrology Success Criteria: Target hydrological characteristics include saturation or inundation for 5 to 12.5 percent of the growing season, during average climatic conditions. During growing seasons with atypical climatic conditions, groundwater gauges in reference wetlands may dictate threshold hydrology success criteria (75 percent of reference). These areas are expected to support hydrophytic vegetation. If wetland parameters are marginal as indicated by vegetation and/or hydrology monitoring, a jurisdictional determination will be performed. 2.0 METHODS Monitoring of restoration efforts will be performed for five years, or until success criteria are fulfilled. Monitoring is proposed for the stream channel, vegetation, and wetland hydrology. In general, the restoration success criteria, and required remediation actions, are based on the Stream Mitigation Guidelines (USACE et al. 2003). Monitoring features are described below and are depicted on Figures 2A -B (Appendix B). Streams The restored stream reaches are proposed to be monitored for geometric activity as follows. • 1750 linear feet of stream profile • 5 riffle cross-sections • 3 pool cross-section The data will be presented in graphic and tabular format. Data to be presented will include 1) cross- sectional area, 2) bankfull width, 3) average depth, 4) maximum depth, 5) width -to -depth ratio, 6) meander wavelength, 7) belt -width, 8) water surface slope, and 9) sinuosity. Substrate analysis will be evaluated through pebble counts at five cross sections and data presented as a D50 for stream classification and tracking purposes. The stream will subsequently be classified according to stream geometry and substrate (Rosgen 1996). Significant changes in channel morphology will be tracked and reported by comparing data in each successive monitoring year. Annual photographs will include 43 fixed station photographs (Appendix B). In addition, the Site contains two stream crest gauges to assist with documentation of Neighbors Branch/Walton Crawley Branch Monitoring Year 2 or 5 (2017) DMS Project No. 92872 December 2017 McDowell County, NC page 4 bankfull events. One bankfull event has been documented to date during monitoring year 2 (2017) making a total of two documented bankfull events (Table 12, Appendix E). Early in Year 1 (2016), several structures were damaged by significant storm events that occurred shortly after Site construction. Warranty repair work was completed in October 2016 to address these issues. The repaired structures appeared stable during Year 2 (2017). They will be monitored throughout the remainder of the monitoring contract to determine if the repair work sufficiently resolved the issues and if any additional repairs will be required. Currently, stream measurements are meeting success criteria. Vegetation Restoration monitoring procedures for vegetation will monitor plant survival and species diversity. Planted areas within the Site include approximately 12.3 acres. After planting of the area was completed, eight vegetation plots were installed and monitored at the Site; annual monitoring results can be found in Appendix C. Annual measurements of vegetation will consist of 8 CVS vegetation plots. A photographic record of plant growth should be included in each annual monitoring report; current monitoring photographs are included in Appendix B. During the first year, vegetation will receive a cursory, visual evaluation on a periodic basis to ascertain the degree of overtopping of planted elements by nuisance species. Subsequently, quantitative sampling of vegetation will be performed as outlined in the CVS-EEP Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008) in September of the first monitoring year and annually between June 1 and September 30 for the remainder of the monitoring period until vegetation success criteria are achieved. Year 2 stem count measurements indicate planted stem densities are well above the required 320 stems per acre. Planted stem density across the Site is 440 planted stems per acre (Table 9, Appendix Q. In addition, all eight individual CVS plots met success criteria based on planted stems alone (Table 7, Appendix Q. Therefore, the Site is currently meeting vegetation success criteria. Wetland Hydrology Two groundwater monitoring gauges were installed to take measurements after hydrological modifications were performed at the Site. Hydrological sampling will occur quarterly throughout the growing season (March 26 to November 5). Approximate locations of gauges are depicted on Figure 2A (Appendix B) and hydrology data can be found in Appendix E. Both gauges were saturated or inundated for well over 12.5 percent of the growing season. The groundwater level at both gauges remained within 12 inches of the surface for the entire growing season (225 days). Gauge 1 malfunctioned for 6 days (July 29 to August 3, 2017) during the growing season. It is unclear why the gauge was not taking measurements during this time, but it appeared to be functioning properly before and after the malfunction, and it was checked and reset at the time of the next data download. The gauge had no more issues for the remainder of the growing season. Based on precipitation data as well as data from Gauge 2, it is expected that this gauge would have continued to be saturated/inundated during this 6 day period. Wetland hydrology is currently meeting success criteria.

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 likley 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.
