Monitoring Year 4 of 5 (2015) DMS Project Number 671 October 2015 Alamance and Chatham Counties, North Carolina Table of Contents 1.0 EXECUTIVE SUMMARY The Greenbrier Stream Restoration Site (Site) is situated within the United States Geological Society (USGS) hydrologic unit 03030003 and North Carolina Division of Water Quality (NCDWQ) Priority Sub -basin 03-06-12. The Site is located approximately 8 miles north of Siler City at the crossing of Staley -Snow Camp/Pleasant Hill Church Road over Greenbrier Creek. The Site is encompassed within a 50.48 acre easement located in three parcels, individually owned by Jerrold Murchison (32.94 acres), Charles Cheek (0.52 acres), and Larry Matthews (17.02 acres). Primary land uses were active row crop production on the Murchison parcel and active pasture on the Matthews/Cheek parcels. Project streams, Greenbrier Creek and an Unnamed Tributary (UT) to Greenbrier Creek, became impaired from poor land management, stream dredging, upstream disturbances, and human impacts. This report (compiled based on North Carolina Division of Mitigation Services' (NCDMS)'s Procedural Guidance and Content Requirements for DMS Monitoring Reports Version 1.4 dated 11/7/11) summarizes data for Year 4 (2015) annual monitoring. The project goals are to: • Improve water quality by reducing nutrient loading from a livestock operation in a water supply watershed. • Reduce the high level of sediment loading to the stream from steep, eroding banks. • Improve both aquatic and terrestrial riparian buffer habitat. These goals will be accomplished through the implementation of the following objectives: • Preservation and protection of important wetlands and stream channel reaches upstream of the Matthews property. • Improvement of water quality (reduction of nutrient and sediment inputs) by creating a vegetated riparian buffer filter strip between the stream and livestock operations currently on the property. • Reduction of high sediment loads in the stream through stabilization of eroding channel banks. • Improvement of deteriorated aquatic habitat by reduction of nutrient and sediment loads in the streams, providing more variable stream channel geometry and creating more opportunities for carbon inputs from trees in the restored buffer zone. • Improvement of terrestrial habitat through restoration of diverse native woody vegetation in the riparian buffer zone and control of invasive Chinese privet (Ligustrum sinense). Vegetation success criteria dictate that an average density of 320 stems per acre must be surviving in the first three monitoring years. Subsequently, 290 stems per acre must be surviving in year 4 and 260 stems per acre in year 5. Stem counts will be based on an average of the evaluated vegetation plots. Based on the number of stems counted, average densities were measured at 499 planted stems per acre (excluding livestakes) surviving in year 4 (2015). In addition, each individual plot met success criteria based on planted stems with the exception of plots 5 and 7, which were 3 stems and 1 stem shy of success with 202 planted stems per acre and 283 planted stems per acre, respectively. However, when including naturally recruited stems of black walnut (Juglans nigra) and black locust (Robinia pseudoacacia) both plots 5 and 7 met success criteria. Plot 5 is adjacent to the unnamed tributary, which is characterized by dense fescue that may have outcompeted some of the planted bare root seedlings shortly after construction. Plot 7 is characterized by a dense herbaceous layer as well as several mature trees that may have contributed to planted stem mortality in this area. Supplemental planting at the Site occurred on February 13 and 14, 2012, in response to the contractor's vegetation warranty assessment (Appendix F). During this effort, 1952 bare root and 1 -gallon trees were planted at the Site. Supplemental planting appears to have resulted in vegetative success across the majority of the Site. Greenbrier Creek (final) Axiom Environmental, Inc. Monitoring Year 4 of 5 (2015) DMS Project Number 671 October 2015 Alamance and Chatham Counties, North Carolina page 1 Chinese privet (Ligustrum sinense) and Japanese privet (Ligustrum japonicum) were observed scattered throughout the site; however, these dense areas were treated several times over the course of the 2015 monitoring period. Invasive treatments appear successful, with just several small privet populations remaining onsite (Figure 2A, Appendix B). In addition, scattered stems of Bradford pear (Pyrus calleryana) and multiflora rose (Rosa multiflora) are present in minimal numbers within the Site. Herbaceous species including Japanese stiltgrass (Microstegium vimineum) and fescue (Festuca sp.) are found across the entire Site. Microstegium is found in portions of the Site that are covered by mature canopy along the upstream portion of the unnamed tributary, downstream portions of Greenbrier Creek, and throughout the preservation reach. Fescue is found in open areas previously maintained as pasture. With the exception of the impounded and previously impounded areas, vegetation within the preservation reach is well-established with scattered occurrences of invasive species. Three small but dense populations of Tree of Heaven (Ailanthus altissima) were observed on the eastern edge of the preservation reach (Figure 213, Appendix B). Additionally, Japanese honeysuckle (Lonicera japonica), Chinese privet (Ligustrum sinense), and microstegium (Microstegium vimineum) were observed scattered throughout the reach. A visual assessment and geomorphic survey were completed for the Site, and indicated that the project reaches were performing within established success criteria ranges as shown below. Due to contracting issues, no baseline data was collected for this project. Although there are no baseline cross-sections to compare with Year 4 (2015) measurements, the Year 1 (2012) cross-sections should serve as an adequate baseline. No significant bank erosion was recorded. In addition, no significant aggradation or degradation of the bed was noted. A total of six bankfull events have occurred within three different monitoring years. Stream Success Criteria (from approved Restoration Plan 2008): • Success is defined as the documentation of no substantial aggradation or degradation of the channel or banks. • Downcutting, deposition, bank erosion, and an increase in sands or finer substrate material must be documented for assessment by the regulatory agencies. • Comparison of existing condition BEHI values with BEHI values computed after vegetation is established will indicate bank stabilization trajectories. • A minimum of two bankfull events must occur in separate years within the five-year monitoring. Beaver have been an ongoing issue within the Site and are being closely monitored and trapped when necessary. Two dams were observed on restoration reaches during year 4 (2015) monitoring activities, one in the vicinity of cross section 8 and one near the downstream -most easement crossing. (Dams 1 and 2, Figure 2A, Appendix B). Currently, one large, well-established impoundment is located on the preservation reach consisting of three major beaver dams (Dams 3, 4, and 5, Figure 2B, Appendix B). This impoundment is characterized by standing water and a lack of living woody stems. Several smaller dams were removed during summer 2015, however few woody stems are surviving in the previously impounded footprint. It does not appear that natural recruits are becoming established in these areas at this time. The currently impounded and previously impounded areas are depicted on the Current Conditions Plan View Map (Figure 213, Appendix B). Fencing along the downstream ford has been heavily damaged by debris during high flow events. Additionally, a small section of fencing has failed in the ford on the unnamed tributary, and some signs of Greenbrier Creek (final) Axiom Environmental, Inc. Monitoring Year 4 of 5 (2015) DMS Project Number 671 October 2015 Alamance and Chatham Counties, North Carolina page 2 livestock activity within the easement at the upstream portion of this tributary were observed (Figure 2A, Appendix B). 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 DMSs website. All raw data supporting the tables and figures in the appendices is available from DMS upon request. 2.0 METHODOLOGY 2.1 Vegetation Assessment Twelve vegetation plots were established and marked after construction with four -foot metal U -bar post demarking the corners with a ten foot, three-quarter inch PVC at the origin. The plots are 10 meters square and are located randomly within the Site. These plots were surveyed in early July for the Year 4 (2015) monitoring season using the CVS -DMS Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008)(http://cvs.bio.unc.edu/methods.htm); results are included in Appendix C. The taxonomic standard for vegetation used for this document was Flora of the Southern and Mid -Atlantic States (Weakley 2012). 2.2 Stream Assessment Annual stream monitoring was conducted in late March 2015. Fourteen permanent cross-sections, eight riffle and six pool, were established and will be used to evaluate stream dimension; locations are depicted on Figure 2A (Appendix B). Cross-sections are permanently monumented with 4 -foot metal garden posts at each end point. Cross-sections will be surveyed to provide a detailed measurement of the stream and banks including points on the adjacent floodplain, top of bank, bankf ill, breaks in slope, edge of water, and thalweg. Data will be used to calculate width -depth ratios, entrenchment ratios, and bank height ratios for each cross-section. In addition, photographs will be taken and pebble counts will be conducted at each permanent cross-section location annually. Two monitoring reaches were established (the unnamed tributary and Greenbrier Creek) and will be used to evaluate longitudinal profile; locations are depicted on Figure 2A (Appendix B). Longitudinal profile measurements will include average water surface slopes and facet slopes and pool -to -pool spacing. Measurements of channel pattern (belt -width, meander length, and radius of curvature) was proposed for Year 1 (2012); however, the design channel was developed at a sinuosity of 1.0-1.1, resulting in no measurable meander bends, belt widths, or radius of curvature. Two crest gauges were installed onsite; one on the unnamed tributary and one on Greenbrier Creek, upstream of the confluence. These will be used to document bankfull events throughout the monitoring period. Additionally, thirty-one permanent photo points were established throughout the restoration reach (14 cross-sections, 12 vegetation plots, and 5 fixed station photos). Photographs are included in the Appendices. Greenbrier Creek (final) Axiom Environmental, Inc.

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. % of Mapping CCPV Number of Combined Easement Ve etation Cateaory Definitions Threshold Depiction Polygons Acreage Acreage Tan and Pink 4.

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.

Smith Great American Insurance Company 580 Walnut Street Cincinnati, OH 45202 Re: Greenbrier Creek Stream Restoration Site SCO # 0406210-02 Vegetation Warranty Items Dear Ms. Cheatham: As stated in the November 8, 2011 letter addressed to you from Ed Hajnos, portions the Greenbrier Creek project site did not meet the vegetation warranty as stated in contract documents. As per SCO contract 0406210-02 Special Provision Section 6.0, bare roots were to be planted at 680 stems per acre, and containerized seedlings at 435 per acre, of those 80% minimum were to survive for one year from Project Acceptance. The warranty period began 2/28/2011 and will expire 2/28/2012. Field data is summarized below and supplemental information about replant requirements is attached. Vegetation assessment methodology Planted vegetation at the Greenbrier Creek site has been assessed once since February 2011 project planting; on September 28, 2011 by the Owner. Data collected during the sampling effort report higher plant mortality than contractually permissible. Warranty replant numbers are based on the data collected. Field methodology and data are described below. September 28, 2011 sampling Fourteen (14) vegetation plots were established, each 1,076 sq ft (25m x 4m) in Zone 4 of the original planting plan. All planted bare root and shrubs present within the plot were counted towards the warranty criteria, including those that were top -dead but were re -sprouting at their base. Given 680 stems were planted per acre, 544 per acre were required to survive 1 year, or 13 MODE R North Carolina Ecosystem Enhancement Program, 1652 Mail Service Center, Raleigh, NC 27699-1652 / 919-715-0476 / www.nceep.net per plot to meet the 100% warranty.

North Carolina Division of Water Quality 1617 Mail Service Center Raleigh NC 27699-1617 SUBJECT: June 12, 2007 EEP Nutrient Offset meeting summary This correspondence is provided to summarize our June 12, 2007 meeting with you, Tom Reeder, Suzanne Klimek, Jim Stanfill and myself. The meeting was held in an attempt to clarify some issues related to EEP's use of riparian buffers to mitigate for Nitrogen and Phosphorus. It is important to come to a common understanding on these issues related to nutrient offset mitigation credit generation as we plan the implementation of mitigation projects. Below are the topics we discussed as they were presented in our May 14, 2007 letter to you. A surmnary of our discussions is below each topic in italics. We invite your input and response to ensure we have captured our discussions accurately. Riparian Buffer N Reduction Efficiencies: With regard to the January 4, 2007 report detailing your discussions of NO3 — N reduction, we would like to clarify whether the benefits of land use change and the benefit of periodic overbank flooding have been considered in the buffer efficiency calculations. We also want to discuss EEP's buffer widths and the efficiencies that should be used for buffers 100 feet or greater. A 50% efficiency was and is used in our calculations of buffer efficiency for our offset projects. Our projects typically have 200 foot buffer widths. The underlying questions here were — Can EEP get more credit for buffers that are wider than 50 feet by using higher efficiency rates as shown in the NLEWpaper? As a group we agreed to use an overall efficiency of 50%for riparian buffers used to offset nutrients regardless of width. Rich Gannon noted that although higher efficiencies were suggested in the "NLEW" paper for buffers wider than 50 feet, these numbers are not widely verified It is therefore appropriate to use 50% to determine reductions. Jim Stanfill agreed noting that EEP buffers are often 200 feet wide and although using a higher efficiency would generate greater mitigation credit, the 50 % number had been used up to this point and EEP would continue to use that to calculate credits. 2. Level Spreaders: The use of level spreaders on riparian buffers not subject to concentrated flow needs to be discussed. It is our understanding that guidance on level spreaders may only be meant to apply to those riparian buffers being used as "onsite" treatment BMPs by permitees. We assume the guidance does not apply to riparian buffer restoration as typically done by EEP, but would like to discuss and get clarification on that issue. The standard is to provide dose flow through buffers. Because EEP would often need to actually clear portions of riparian buffers to install level spreaders, and also because EEP 's buffers are often 200 feet wide, we do not think the use of level spreaders is necessary as long as diffuse flow is maintained. Tom Reeder and Rich Gannon agreed that level spreaders would not necessarily be needed on EEP buffers in rural areas where diffuseflow is not an issue. FA Rest7o ' .. E .. Prot2Gt, Our Stat& CDEN �• � NCDENR North Carolina Ecosystem Enhancement Program, 1652 Mail Service Center, Raleigh, NC 27699-1652 / 919-715-0476 / www.nceep.net Land Use Change: If EEP purchases agricultural land to do riparian buffer restoration we believe EEP should get credit for restoration of the entire buffer width. That is, the first 50 feet of buffer would not be excluded from our credit calculations. The argument for this is that while the act of EEP purchasing the property may have changed a property's land use and, therefore, made it subject to the buffer rules, the EEP is actually implementing an active riparian buffer restoration project on that land, not simply taking it out of agricultural use. Furthermore, if EEP does not purchase these lands, there will be no land use change. Tom and Rich agreed with this statement- EEP should get credit for the entire width restored. 4. We also have some questions about the Jordan nutrient offset trading program, but staff are still reviewing the information that has been released. EEP will need to provide comments on the Jordan rules to ensure the fees are set appropriately and the requirements (service area) are attainable. This area is likely to have higher implementation costs and less opportunity for lower cost buffers as nutrient offset mitigation. If EEP will accept payments in this area, we must be able to afford to implement projects. 5. EEP's Nutrient Offset Accounting Methods: Regarding EEP's nutrient offset requirements- Jim Stanfill discussed how we measure the total pounds for 30 years when we accept a nutrient offset payment and take on a requirement. Our projects are setup to offset a total numbers of pounds and, therefore, we may have "shorter" (less than 30 years) more intense projects_ Rich and Tom were in agreement with our accounting methods. 6. Riparian Buffer Mitigation Site location — clarification of intent of rules: In the Randleman watershed (for Cape Fear 03), EEP staff have questioned where- upstream or downstream- in the watershed the mitigation should take place. Mitigation that EEP already has downstream of the reservoir can be used, but new pursuits should be upstream in order to protect the reservoir. Likewise, in Catawba, new projects should be downstream of Lake James to be used as mitigation credit. EEP staff also clarified that the rules do not have a time requirement for EEP to provide the mitigation, but that the program uses the same time requirements as the MOU. Tom and Rich were also agreeable to this. 7. Rich requested that EEP allow for transparencies in its program and asked for us to provide as much data as possible in our annual report and work on information to be included on EEP's Web site. EEP agreed and is working to set up a specific web page at the program's web site devoted to the Nutrient Offset Program. Thank you for taking the time to discuss these issues with us.
