INTRODUCTION The Anderson Farm Stream Mitigation Bank site (approximately 25 acres) consisted primarily of channelized first -order stream systems that had been historically altered as a result of silvicultural and livestock management practices prior to the initiation of restoration activities. The site is part of a 103 -acre parcel located just west of Mag Sluder Road, approximately ten miles north of Asheville, North Carolina, in Buncombe County. The site consists of moderately to steeply sloped terrain and is bisected by two main stream systems which flow southward into Newfound Creek, a third -order stream located in the French Broad River Basin (8 -digit Hydrologic Unit 06010105) (Subbasin 06010105090020). Based upon the as - built survey, a total of 2,800 linear feet (If) of stream restoration was completed in addition to 555 If of stream enhancement (Appendix A). Approximately 16 acres (ac.) of riparian habitat were also restored through the planting of native hardwood species. As a result, the restoration effort is providing for increased in -stream habitat, floodwater storage, nutrient retention/sediment reduction, and riparian habitat expansion for resident and migratory fauna. II. RESTORATION SUMMARY A. On-site Construction On-site construction was conducted between August 5, 2013, and October 1, 2013. Early activities focused on the removal of invasive vegetation and large trees within the proposed construction zone. Trees were stockpiled and later utilized as grade control structures per the engineer's specifications. Following the clearing stage, excavation of the stream bank and contouring of the riparian area were conducted. This level of disturbance was conducted in 500 -foot (ft) sections throughout the property to minimize the risk of large-scale erosion and bank failure. Topsoil was stockpiled and redistributed following the establishment of stable bank slopes. Excavated material was wasted in one of two designated areas within the Anderson Farm property. Restoration within the stream channel was conducted in concert with the grading activities. A majority of the in -stream work focused on the installation of log and/or stone sills across the existing channel. These structures serve as grade control features and support the development of different habitat niches throughout the reach. Numerous pools and constructed riffles were also established and/or stabilized to restore the natural features of the streambed. In addition, three ephemeral drainage channels, located on Anderson Farm Stream Mitigation Bank 2 Annual Monitoring Report (Year 5) January 2019 the western side of UT -1 and UT -3, were also stabilized using reinforced coir fiber matting. Rock -lined pools were also engineered along these features to dissipate runoff velocities prior to their intersection with the restored channel. B. Planting Planting of the site was conducted between December 30, 2013, and January 1, 2014. During this period a mixture of livestakes and bare root seedlings were planted throughout the site. Livestakes were installed every two feet along the restored streambank. Bare root seedlings were planted on 8 -foot spacings (approximately 680 stems per acre) throughout the 16 -acre riparian buffer area. Table 1 contains a complete list of the planted species. Supplemental planting near the confluence was also conducted following the Year 1 monitoring event. III. MONITORING PLAN A. Hydrologic Monitoring Wells Documentation of stream flow within the project is being conducted using three pressure transducers (one in each restored reach). One additional gauge has also been installed within the area targeted for enhancement. All four wells were re -installed on June 26, 2014. One of the wells (UT -2) was replaced again in December 2017. These gauges are measuring the elevation of water in the channel throughout the duration of the project and will be used to determine if the project is meeting the applicable "success criteria" related to the total number of bankfull events. B. Vegetation Monitoring Given the size of the project, 2% of the planted riparian areas are monitored via the establishment of permanent 0.10 -ac. plots. These areas are located within approximately 16 acres in two different habitat types. Per the approved mitigation plan, a total of five plots were established. GPS coordinates for the centers of each sampling plot were recorded and are included with the as -built survey (Appendix A). During monitoring, surviving planted individuals and volunteers are identified, measured, and enumerated within each plot.

Stream Channel Monitoring Given the size, uniform design, and moderate slope (2%) of the proposed project area, cross-sections were established every 500 feet of stream length (totaling 6 permanent stations). Placement of these stations was designed to assess the performance of potential problem areas (e.g. severe erosion, structural failure, etc.) within the restoration areas. These stations were evenly distributed between riffles and pools throughout the project (Appendix A). D. Success Criteria The stream and riparian buffer restoration effort will be evaluated based upon performance criteria related to vegetative density and stream stability. A total of five (5) monitoring events will occur following completion of the proposed work. Additional monitoring may be required if subsequent plantings are deemed necessary to meet the success criteria listed below. Note that non -planted individuals of characteristic species may volunteer into the restored areas. Suitable volunteers are an important component of the riparian area, as they serve as indicators for appropriate hydrologic regimes and provide increased diversity. The presence of suitable volunteers also demonstrates trending of the site toward vegetative success. The primary success criteria for the restored stream systems will be: (1) Documentation of 2 bankfull events using techniques discussed below within a normal rainfall year during the initial 5 years of monitoring. These events must occur in separate years. Additional monitoring maybe necessary in the event of abnormal climatic conditions. (2) Demonstrated density of planted species to meet or exceed 260 trees per acre at the end of 5 years (post - planting). Level I Monitoring will be required for the Anderson Farm Stream Mitigation Bank as detailed in the Stream Mitigation Guidelines. Monitoring will occur five times in the years following completion of construction. Monitoring reports will be prepared each monitoring year and will include completed Channel Mitigation Monitoring Sheets with current data, a discussion of any deviations, and whether they are indicative of a stabilizing or destabilizing situation. Anderson Farm Stream Mitigation Bank 5 Annual Monitoring Report (Year 5) January 2019 IV. MONITORING RESULTS (YEAR 5) A. Vegetation Monitoring Vegetation monitoring was conducted at the site on October 6, 2018. A total of 277 stems were counted throughout the five plots, which correlates to an average of 554 stems per acre within the project area (a decrease in 36 stems per acre over the previous year). Tulip Poplar (Liriodendron tulipifera) was the most abundant woody specie, with a total of 63 individuals. Other planted species such as Green Ash (Fraxinus pennsylvanica), American Sycamore (Platanus occidentalis), and Sugar Maple (Acer floridanum) were also prevalent within the monitoring plots. All five of the plots contained sufficient densities of planted and volunteer species. Plot #3, located near the confluence, registered the highest density with 78 individuals (down from 94 the previous year). This was likely due to the supplemental planting that occurred in early 2016. Supplemental planting was necessary to counteract poor survivorship due to drought and soil compaction from previous land use. See Appendix B for photographs of the monitoring plots during the October 2018 event. Individual plot data is presented in Appendix C. Table 2. Summary of Monitoring Plot Data 2018 Plot Number Number of Planted Species Density per Acre 1 40 400 2 57 570 3 78 780 4 63 630 5 39 390 TOTAL 277 -- AVERAGE 554 B. Hydrologic Monitoring Hydrologic monitoring wells were reinstalled at the site on June 26, 2014, and one (UT -2) was reinstalled again in December 2017. Each well records the water level in the stream every 15 minutes, which is sufficient to capture the impact of most rainfall events. The well installed at UT -2 captures data from -22 inches to 0" (top of unit). The remaining wells capture data ranging from -42 inches (") (bottom of thalweg) to 0" (top of unit). Rainfall levels were average to below average from January to mid-May 2018. Totals Anderson Farm Stream Mitigation Bank 6 Annual Monitoring Report (Year 5) January 2019 from June to December were well above average. Corresponding rainfall data reflects the official readings from the climate database at the Asheville Airport (AVL). See Appendix D for WETS table information and individual well graphs. UT -1 b This well is located at Cross -Section #2 near station 17+50 of UT -1b. Based on the design plans, the average bankfull depth for this section is 0.53 ft. Data from 2018 depict the target hydrologic regime for this first order stream with a small drainage area. Recorded events were typically brief, lasting 15 to 30 minutes. A 1.05" event on May 11th, 2018 resulted in a bankfull event of -33.0" at this site. A series of smaller rain events between September 24th and 27th maintained bankfull levels for several days, cresting at -34.7" UT -2 This well is located at Cross -Section #4 near station 19+00 of UT -2. Based on the design plans, the average bankfull depth for this section is 0.59 ft. The installation of the new well improved data collection accuracy and alignment with measured rain events. A bankfull event measuring -15.0" was recorded on January 12th, 2018 in association with a 0.69" rain event. The January event occurred within a period of normal precipitation. Several other bankfull events were recorded during above-average rainfall levels. UT -2 (Enhancement) This well is located near station 12+00 of UT -2. This section was targeted for enhancement via the removal of invasive vegetation and livestock watering infrastructure. Both of these tasks were completed in conjunction with the construction activities on the remaining portions of the reach. Removal of the livestock infrastructure has allowed the characteristic flow regime to return to this section. Well data provided depict a normal increase in water levels which correlates to measurable rain events during the winter and spring of 2018. Data also reflect higher base flow levels for the remainder of the year, corresponding to the above-average rainfall observed. UT -3 This well is located at Cross -Section #5 near station 10+25 of UT -3. Based on the design plans, the average bankfull depth for this section is 0.63 ft. Recorded data from 2018 depict the targeted hydrologic Anderson Farm Stream Mitigation Bank 7 Annual Monitoring Report (Year 5) January 2019 regime for a small second order stream. A 0.69" rain event on January 121h, 2018, registered a bankfull event of -31.2". Well data from the remaining portion of the year is missing due to equipment malfunction. C. Stream Channel Monitoring Survey work was conducted at each of the six permanent stations in October 2018. Cross-section #1 has experienced a decrease in pool depth of 0.51" compared to the as -built survey. The riffle present at Cross- section #2 has also experienced a small amount of accretion, but has remained stable. Cross-section #3 showed a decrease in pool depth and has returned to dimensions resembling the as -built survey. Cross- sections #4 showed a small decrease in bankfull depth, while bankfull area remained nearly identical to the as -built. Pool depth at Cross-section #5 was nearly identical to the as -built survey. Mean and maximum depths at Cross-section #6 also showed little to no change in channel geometry. No bank failures or major structural issues were observed during the site survey. Overall, the site has performed well through a number of large rain events and will likely benefit from increased vegetative cover over the course of the remaining monitoring schedule (see Section V below). See Appendix E for specific information on the individual cross-sections and the requested comprehensive data table. V. ADAPTIVE MANAGEMENT Based on comments received from the USACE following a site visit on September 24th, 2018, the bank sponsor has agreed to the following adaptive managements actions: 1) Kudzu Management — Kudzu will be physically cut and removed throughout the entire UT -1a reach. This removal will be followed by multiple herbicide treatments. In addition to these efforts, a controlled burn will be conducted outside of the project boundary to provide an additional buffer against further infestation. These activities will take place throughout 2019. 2) Supplemental Planting — Additional livestakes and 1 -gallon hardwood saplings will be installed in the southern section of the project area. 700 livestakes will be installed along the section of UT -3 where survivorship was extremely low. 350 1 -gallon plants will be installed in the adjacent valley in an effort to achieve the target ecological community. The supplemental planting is currently scheduled for February 2019. A report will be submitted to the USACE following the completion of these activities. Anderson Farm Stream Mitigation Bank 8 Annual Monitoring Report (Year 5) January 2019 VI. CONCLUSION The Anderson Farm Stream Mitigation Bank has performed as designed during the fifth year following construction. Stream features remain intact and stable after several large rain events, and a variety of native hardwood species, grasses, and shrubs occupy the floodplain ecosystem. Each of the three reaches registered definitive bankfull events. Natural hydrologic conditions were also enhanced in the upstream section of UT -2. Vegetation densities increased as compared to Year 4 monitoring results due in part to the supplemental planting and adequate precipitation levels during the growing season. Given the current population levels, it is anticipated that the site will maintain sufficient densities to meet the aforementioned success criteria in the remaining years. The sponsor has agreed to more aggressively manage the kudzu throughout 2019 as well as to conduct additional planting to ensure that the site continues to progress towards the goal of reestablishing the low mountain alluvial and bottomland forest ecosystems.
