Water quality stressors affecting the Project included livestock production, agricultural practices, and lack of riparian buffer. The Project presents stream restoration, enhancement, and preservation generating 4,115.930 Cold Stream Mitigation Units (SMU). The Project’s total easement area is 25.28 acres within the overall drainage area of 87 acres. Grazing livestock historically had complete access to both the stream reaches, resulting in bank erosion, sediment deposition, and channel incision. The lack of riparian buffer vegetation, deep- rooted vegetation, and unstable channel characteristics contributed to the degradation of stream banks and surrounding floodplain area. The stream design approach for the Project was to combine the analog method of natural channel design with analytical methods to evaluate stream flows and hydraulic performance of the channel and floodplain. The analog method involved the use of a reference reach, or “template” stream, adjacent to, nearby, or previously in the same location as the design reach. The template parameters of the analog reach were replicated to create the features of the design reach. The analog approach is useful when watershed and boundary conditions are similar between the design and analog reaches. Hydraulic geometry was developed using analytical methods to identify the design discharge. The wetland approach was closely tied to the stream restoration in that wetland hydrology and vegetation have been re-established as a product of restoring the natural stream system and riparian area along with other hydrologic improvement activities. The Project has been constructed and planted and will be monitored on a regular basis throughout the seven-year post-construction monitoring period, or until performance standards are met. The Project will be transferred to the NCDEQ Stewardship Program. This party shall serve as conservation easement holder and long-term steward for the property and will conduct periodic inspection of the site to ensure that restrictions required in the conservation easement are upheld. Funding will be supplied by the responsible party on a yearly basis until such time an endowment is established. 1.2Project Goals and Objectives Through the comprehensive analysis of the Project’s maximum functional uplift using the Stream Functions Pyramid Framework, specific, attainable goals and objectives will be realized by the Project. These goals clearly address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2009 French Broad River RBRP. These goals and objectives reflect those stated in the Monkey Wall Project Final Mitigation Plan. The Project goals are: Monkey Wall Project1As-Built Baseline Monitoring Report Project #100069October2022 Improve water transport from watershed to the channel in a non-erosive manner in a stable channel; Improve flood flow attenuation on-site and downstream by allowing for overbank flows and connection to the floodplain; Restore native floodplain and riparian vegetation; and Improve instream habitat; Reduce sediment, nutrient, and fecal coliform inputs into stream system; Indirectly support the goals of the 2009 French Broad RBRP to improve water quality and to reduce sediment and nutrient loads, especially in the Big Rock Creek watershed. The Project goals were addressed through the following project objectives: Designed and reconstructed the stream channel to convey bankfull flows while maintaining stable dimension, profile, and planform; Added in-stream structures and bank stabilization measures to protect the restored stream; Installed habitat features such as brush toes, woody materials, and pools of varying depths to the restored stream; Removed the 268-linear foot rock wall located on the most upstream portion of G2 which daylighted the existing stream and restored the natural profile of the channel; Increased forested riparian buffers to at least 30 feet on both sides of the channel along the Project reach with a hardwood riparian plant community; Treated exotic invasive species; and Established a permanent conservation easement on the Project that excludes future livestock from the stream channel and its associated buffers and prevent future land-use changes. Functional uplift, benefits, and improvements within the Project area, as based on the Function Based Framework, are outlined in the Final Mitigation Plan. 1.3Project Success Criteria The success criteria for the Project follows the 2016 USACE Wilmington District Stream and Wetland Compensatory Mitigation Update, the Monkey Wall Project Final Mitigation Plan, and subsequent agency guidance. Cross section and vegetation plot monitoring takes place in Years 0, 1, 2, 3, 5, and 7. Stream hydrology and visual monitoring takes place annually. Specific success criteria components are presented below. Stream Restoration Success Criteria Four bankfull flow events must be documented within the seven-year monitoring period. The bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until four bankfull events have been documented in separate years. Monkey Wall Project2As-Built Baseline Monitoring Report Project #100069October2022 There should be little change in as-built cross sections. If changes do take place, they should be evaluated to determine if they represent a movement toward a less stable condition (for example down-cutting or erosion) or are minor changes that represent an increase in stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross sections shall be classified using the Rosgen stream classification method, and all monitored cross sections should fall within the quantitative parameters defined for channels of the design stream type. Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be above 2.2 within restored riffle cross sections. Channel stability should be demonstrated through a minimum of four bankfull events documented in the seven-year monitoring period. Digital images are used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should not indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A series of images over time should indicate successional maturation of riparian vegetation. Vegetation Success Criteria Specific and measurable success criteria for plant density within the riparian buffers on the Project follow IRT Guidance. The interim measures of vegetative success for the Project is the survival of at least 320 planted three-year old trees per acre at the end of Year 3, 260 trees per acre with an average height of six feet at the end of Year 5, and the final vegetative success criteria is 210 trees per acre with an average height of eight feet at the end of Year 7. Volunteer trees are counted, identified to species, and included in the yearly monitoring reports, but are not included in the success criteria of total planted stems until they are present in the plot for greater than two seasons. Moreover, any single species can only account for up to 50 percent of the required number of stems within any vegetation plot. Any stems in excess of 50 percent will be shown in the monitoring table but will not be used to demonstrate success.

There are also three existing wetlands within the easement area: Wetland A, Wetland B, and Wetland C (WA, WB, and WC, respectively); no wetland mitigation work was completed at the Monkey Wall site. The Project presents 3,227 LF of stream restoration, 120 LF of stream enhancement, and 278 LF of stream preservation, generating 4,115.930 Cold SMUs. To account for areas of more or less than minimum 30-foot buffer widths, credits were adjusted using the USACE Wilmington District Stream Buffer Credit Calculator. The stream mitigation components are summarized below. Mitigation credits are based on the Mitigation Plan Addendum.

Stream restoration incorporated the design of a single-thread, high gradient, cascade and step-pool channel system, with parameters based on cascade and step-pool morphology and reference conditions along the representative reaches within the Monkey Wall site. A combination of analog, empirical, and analytical design techniques were used to determine the design discharge and to verify design stability. Reaches G1 and G2 were designed specific to cascade and step-pool systems for treatment mitigation goals for the site and include a series of cascades and pools connected by riffles and/or boulder and log steps that restore floodplain connectivity to the site. The riffles, steps, and pools provide grade control, energy dissipation and bedform diversity to restore high gradient systems. The following stream treatment was performed on the Project reaches: Monkey Wall Project5As-Built Baseline Monitoring Report Project #100069October2022 Reach G1-A A Preservation approach was used for this reach, due to its high quality, wide riparian buffers, and terrain. Preservation activities included: Minimal buffer planting on the right bank, to increase riparian buffer beyond 75 feet; Livestock exclusion; and Establishing a conservation easement to be protected in perpetuity. Reach G1-B An Enhancement II approach was used for the reach to address eroding banks and channel entrenchment. Enhancement activities included: Livestock exclusion; and Riparian buffer planting to 150-feet. Reach G1-C A combination of Priority I and Priority II restoration was used for this reach to address eroding banks, channel incision, bed degradation and floodplain connectivity. Restoration activities included: Constructing a new single thread channel and floodplain benches in the existing floodplain; Installing log and rock structures to provide grade control with drops no greater than 1.25 feet; Establishing a cascade, step-pool or riffle-pool sequence throughout the reach; Filling the existing channel; Creating floodplain to reduce shear stresses at higher flows; Livestock exclusion; and Riparian buffer planting to a minimum of 30-feet at the downstream end and out to 150-feet everywhere else Reach G2 A combination of Priority I and Priority II restoration was used for this reach to address eroding banks, channel incision, bed degradation, and floodplain connectivity. Restoration activities included: Removing the culvert and associated road at the upstream portion of the reach and tying the channel into a seep located above the culvert; Removing the rock wall, and daylighting the channel, present on the upper portion of the reach; Constructing a new single thread channel and floodplain benches in the existing floodplain; Installing log and rock structures to provide grade control with drops no greater than 1.25 feet; Establishing a cascade, step-pool or riffle-pool sequence throughout the reach; Filling the existing channel; Creating floodplain to reduce shear stresses at higher flows; Livestock exclusion; and Monkey Wall Project6As-Built Baseline Monitoring Report Project #100069October2022 Riparian buffer planting to 150-feet on both sides of the stream. One wetland gauge was installed on the right floodplain of G1-C in WA to monitor wetland hydrology. This data will be reported in yearly monitoring reports. No wetland credits are to be generated on WA; thus, wetland success criteria will not need to be met during the monitoring period. 1.6Construction and As-Built Conditions Stream construction was completed in October 2021 and planting was completed on March 10, 2022. The Monkey Wall Project was built to design plans and guidelines. The as-built stream length was exactly the same as proposed in the mitigation plan plus the stream length that was originally removed under the utility lines; however, the total SMUs for the project increased from 3,874.469 SMUs to 4,115.930 SMUs. This change was due to the relocation of utility lines that were previously within the conservation easement.French Broad Electric relocated the powerline in April 2022 and Country Cable (Zito Media) moved the fiberoptic cable line in October 2022. RES also removed the old utility poles in October 2022. More information regarding this is included in the attached Mitigation Plan Addendum. Swales were added to address small erosional areas that formed as a result of stormwater runoff and seeps encountered during construction. Swale locations are shown on the record drawings included in Appendix E. Minor monitoring device location changes were made during as-built installation; however, the quantities remained as proposed in the Final Mitigation Plan. The original installation of two fixed vegetation plots, 6 and 7, interfered with the relocated powerline easement and were therefore shifted outside of the right-of-way on May 3, 2022. There were no changes made to the planting plan. 1.7Baseline Monitoring Performance(MY0) The Monkey Wall baseline monitoring activities were performed in March and May 2022. All baseline monitoring data is present below and in the appendices. The Project is on track to meet interim success criteria. Vegetation Setup and monitoring of 13 fixed vegetation plots and three random vegetation plots was completed after planting and stream construction on March 24, 2022. The original installation of two plots, 6 and 7, interfered with the relocated powerline easement and were therefore shifted outside of the right-of-way on May 3, 2022. Vegetation data are in Appendix C, associated photos are in Appendix B, and plot locations are in Appendix B. MY0 monitoring data indicates that all plots are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 405 to 809 planted stems per acre with an average of 599 planted stems per acre across all plots. A total of 11 species were documented within the plots. Volunteer species were not noted at baseline monitoring but are expected to establish in upcoming years. The average stem height in the plots was 1.5 feet. Monkey Wall Project7As-Built Baseline Monitoring Report Project #100069October2022 Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. Stream Geomorphology A total of 12 cross sections were installed and geomorphology data collection for MY0 was conducted on March 24, 2022. Summary tables and cross section plots are in Appendix D. Overall the baseline cross sections and profile relatively match the proposed design. The as-built conditions show that shear stress and velocities have been reduced for the restoration reaches. The reaches were designed as a natural mountain cobble-bed channel and remain classified as a mountain cobble-bed channel post-construction. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. The channel is transporting sediment as designed and will continue to be monitored for aggradation and degradation. Stream Hydrology Two stage recorders and two flow gauges were installed on March 24, 2022 and will document bankfull events and flow days, respectively. Stream hydrology will be recorded at a frequency of once per hour and data will be included in the Monitoring Year 1 Report in this section and in the appendices. The gauge locations can be found on Figure 2 and photos are in Appendix B. Wetland Hydrology One groundwater well was installed on the right floodplain of G1-C in WA to monitor wetland hydrology and will record water table depths at a frequency of twice per day. This data will be reported in yearly monitoring reports in this section and in the appendices. No wetland credits are to be generated on WA; thus, there is no hydroperiod success criteria for this groundwater well. 2.0 Methods Stream cross section monitoring was conducted using a Topcon GTS-312 Total Station. Three- dimensional coordinates associated with cross-section data were collected in the field (NAD83 State Plane feet FIPS 3200). Morphological data were collected at eight cross-sections. Survey data were imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. The stage recorders include an automatic pressure transducer placed in PVC casing in a pool at the downstream end of each reach. The elevation of the bed and top of bank at each stage recorder are used to detect bankfull events. The flow gauges also include an automatic pressure transducer placed in a PVC casing in a pool, at the upstream end of each reach. The elevations of the bed, water surface, and immediate downstream riffle are used to determine stream flow. Monkey Wall Project8As-Built Baseline Monitoring Report Project #100069October2022 Vegetation success is being monitored at 13 fixed monitoring plots and three random monitoring plots. Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and density of planted species. Data are processed using the CVS data entry tool. In the field, the four corners of each plot were permanently marked with PVC at the origin and metal conduit at the other corners. Photos of each plot are to be taken from the origin each monitoring year. The random plots are to be collected in locations where there are no permanent vegetation plots. Random plots will most likely be collected in the form of 100 square meter belt transects with variable dimensions. Tree species and height will be recorded for each planted stem and the transects will be mapped and new locations will be monitored in subsequent years. Wetland hydrology is monitored to track the hydrology of the jurisdictional wetland (WA) on site post-stream construction. This is accomplished with one automatic pressure transducer gauge (located in the groundwater well) that will record daily groundwater levels. One automatic pressure transducer is installed above ground for use as a barometric reference. The gauge is downloaded quarterly and wetland hydroperiod is calculated during the growing season. Gauge installation followed current regulatory guidance. Visual observations of primary and secondary wetland hydrology indicators are also recorded during quarterly site visits. 3.0 References Griffith, G.E., J.M.Omernik, J.A. Comstock, M.P.
