(Wildlands) implemented a full -delivery stream mitigation project at the Alexander Farm Mitigation Site (Site) for the North Carolina Department of Environmental Quality (DEQ) Division of Mitigation Services (DIMS). The project restored, enhanced, and preserved a total of 6,722 linear feet (LF) of perennial stream in Alexander County, NC. The Site is located within the DIMS targeted local watershed (TWL) for the Catawba River Basin HUC 03050101 and the NC Division of Water Resources (DWR) Subbasin 03-08-32. The project is providing 4,258.100 stream mitigation units (SMUs) for the Catawba River Basin Hydrologic Unit Code (HUC) 03050101130010 (Catawba 01). The Site's immediate drainage area as well as the surrounding watershed has a long history of agricultural activity. Stream and wetland functional stressors for the Site were related to both historic and current land use practices. Major stream stressors for the Site included channel incision and widening, a lack of stabilizing riparian vegetation, a lack of bedform diversity and aquatic habitat, and agricultural related impacts such as channel manipulation or straightening and concentrated run-off inputs from agricultural fields. The effects of these stressors resulted in channel instability, loss of floodplain connection, degraded water quality, and the loss of both aquatic and riparian habitat throughout the Site's watershed when compared to reference conditions. The project approach for the Site focused on evaluating the Site's existing functional condition and evaluating its potential for recovery and need for intervention. The project goals defined in the mitigation plan (Wildlands, 2019) were established with careful consideration of 2009 Upper Catawba River Basin Restoration Priorities (RBRP) goals and objectives to address stressors identified in the watershed through the implementation of stream restoration and enhancement activities and wetland re-establishment and rehabilitation activities, as well as riparian buffer re -vegetation. The established project goals include: • Improve stream channel stability, • Reconnect channels with historic floodplains, • Improve in -stream habitat, • Reduce sediment and nutrient inputs from adjacent farm fields, • Restore and enhance native floodplain and wetland vegetation, • Exclude livestock, and • Permanently protect the project site from harmful uses. The Site construction and as -built surveys were completed April - May 2020. Planting and baseline vegetation data collection occurred in April 2020. Vegetative plot species were confirmed in early June 2020 after leaf -out. Installation of monitoring features and sediment data collection was completed in April 2020. Fencing installation was completed in July 2020. Minimal adjustments were made during construction and specific changes are detailed in Section 5.1. Baseline (MYO) profiles and cross-section dimensions closely match the design parameters with little variation. The Site has been built as designed and is expected to meet the upcoming monitoring year's success criteria.

GOALS, BACKGROUND, AND ATTRIBUTES 1.1 Project Location and Setting The Alexander Farm Mitigation Site (Site) is in Alexander County approximately 6 miles west of Statesville and 15 miles northeast of Hickory (Figure 1). Unnamed tributaries to Elk Shoals Creek originate within the project limits, and were restored, enhanced, and preserved as part of this project. Elk Shoals Creek drains to Lookout Shoals Lake on the Catawba River, the primary water supply for the City of Statesville. The Site is located within the Elk Shoals Creek targeted local watershed (TLW) Hydrologic Unit Code (HUC) 03050101130010 and is being submitted for mitigation credit in the Upper Catawba River Basin 03050101. Located in the Northern Inner Piedmont belt within the Piedmont physiographic province (NCGS, 1985), the project watershed is dominated by agricultural and forested land. The Site contains two unnamed tributaries, UT1 and UT1A, and eighteen riparian wetlands; however, no credit is being sought for project wetlands. For this project UT1 was broken into six reaches (Reach 1A, Reach 113, Reach 2, Reach 3, Reach 4A, and Reach 413). The project Site is bisected by Elk Shoals Church Loop Road between Reach 2 and Reach 3. The overall Site topography consists of a gradually sloped valley running through the center of the project. Upstream of Elk Shoals Church Loop Road, the Site is characterized by a moderate slope. UT1 Reach 1 originates within the Site limits at a spring head and flows downslope through a moderately confined valley surrounded by open pasture. Approximately 600 feet downstream of the headwaters, the valley widens and continues downstream as a broad gently sloping floodplain to Elk Shoals Church Loop Road. Downstream of the road crossing, UT1 continues flowing south within a broad gently sloping floodplain to its confluence with UT1A from the left floodplain, where it originates as a wetland seep. At the confluence, UT1A and joins UT1 and continues south to its confluence with to Elk Shoals Creek within a broad alluvial floodplain. The site drains approximately 256 acres of rural land. Prior to construction activities, the streams throughout the Site were in various stages of impairment related to the current and historical agricultural uses. UT1 Reach 1 was mostly incised and disconnected from the floodplain, with short segments of floodplain connectivity. The bed was trampled and severely impacted by cattle. Bedform diversity and habitat was very poor, primarily due to sedimentation and incision. UT1 Reach 2 was overwide and trampled but well vegetated with herbaceous species from abutting wetlands. As it approached the Elk Shoals Church Loop Road, the creek alternated between areas of incision and floodplain connection. The bed was choked with fine sediments and trampled, with several active cattle wallow areas. UT1 Reach 3 begins just downstream of the Elk Shoals Church Loop 48-inch culvert. It is wooded and cattle have been excluded from this section of the farm. The majority of the reach consisted of low, stable stream banks with a few scour pockets located near ATV crossings. Within the wooded valley, UT1 Reach 4 was extensively eroded, incised, and laterally unstable with erosion present on both banks, transverse bars, and sharp meander bends. As the stream exited the wood line, bank heights decreased, the channel narrowed, and the stream banks became well vegetated with annual herbaceous species; however, the channel was still deeply incised and disconnected from its historic floodplain. Pre -construction conditions are outlined in Table 4 of Appendix 1 and Table 6 of Appendix 2. 1.2 Project Goals and Objectives The Site is providing numerous ecological benefits within the Upper Catawba Basin. The project goals were established with careful consideration to address stressors that were identified in the 2009 Upper Catawba Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 1-6 River Basin Restoration Priorities (RBRP) report. The project has improved stream functions through stream restoration and the conversion of maintained agricultural fields into riparian buffer within the Upper Catawba River Basin, while creating a functional riparian corridor at the site level. Improvements are outlined below as project goals and objectives. Goals Objectives Restore stream channels that will maintain a stable pattern and profile considering the hydrologic and sediment inputs to the Improve stream channel stability. system, the landscape setting, and the watershed conditions.

Construction activities were completed in April 2020 by Baker Grading & Landscaping, Inc. Turner Land Surveying completed the as -built survey in May 2020. Following construction, Bruton Natural Systems, Inc. completed riparian planting in April 2020 and wetland planting in May 2020. A copy of the final sealed survey is included in Appendix 4. Field adjustments made during construction are described in further detail in section 5.1 and depicted in the record drawings in Appendix 4. Please refer to Appendix 1 for detailed project activity, history, contact information, and watershed/site background information. 1.3.1 Project Structure Project mitigation components are outlined in the Mitigation Assets and Components Table (Table 1) and depicted in the As -built Monitoring Plan View Maps (Figures 3.0 - 3.3) that are located in Appendix 1. 1.3.2 Restoration Type and Approach The mitigation approaches proposed for the streams on the Site were developed to achieve the potential for functional uplift relative to the existing conditions on the site. The site plan includes elements of stream restoration, enhancement II, and preservation. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 1-7 Restoration reaches were constructed as Priority 1 except where Priority 2 grading was needed to transition with existing grade elevations. Restoration reaches were designed to create stable, functional stream channels with improved dimension, pattern, and profile. Cross -sectional areas were sized for frequent overbank flows. Bedforms were stabilized and varied with the use of in -stream structures to reduce channel erosion and improve aquatic habitat. Enhancement II reaches retained their existing dimension, pattern, and profile. Mitigation activities included localized bank stabilization and repairs in areas where damage was more significant. Mid -channel bars were excavated, and the existing alignment was stabilized. Invasive vegetation was treated by either excavation or herbicide. Reaches that were stable and functioning were preserved to protect them from future impacts from cattle, agricultural production, timbering and/or site development. Timber limits were established approximately 30-ft — 50-ft outside of the conservation easement to provide additional wooded buffer. Vernal pools were placed at discrete runoff locations within the conservation easement to provide additional protection from timbering practices. All the project reaches are protected in perpetuity with the implementation of a conservation easement. Fencing was installed outside of the easement to exclude cattle from the project area. Invasive vegetation such as Chinese Privet, multi -flora rose, and alligator weed were treated by either excavation or herbicide, as needed throughout the Site. The streambanks and floodplains were planted with native woody and herbaceous species as depicted in the planting plan of the record drawings located in Appendix 4. UT1 Reach 1A and 113 UT1 Reach 1A begins as a perennial stream located at Station 100+00just downstream of a spring head stabilized by a series of rock sills. UT1 Reach 1A flows southward and receives drainage from multiple small swales that were stabilized to prevent erosion. UT1 Reach 113 begins at Station 107+70 and continues flowing southward and receives drainage from multiple stabilized wetland seeps and drainage swales. Reach 113 ends at an easement break at Station 117+39 for an existing permanent culverted farm road crossing. UT1 Reach 1A and 113 were designed as Rosgen B-type channels and were improved through Priority 1 restoration. The channel beds were raised to reconnect to the existing floodplain. In -stream structures such as rock sills, log sills, constructed riffles, and brush toes were added for stream stability, grade control and habitat variability. The downstream extent of UT1 Reach 113 was slightly realigned to improve hydraulics and add additional stability to the channel before reconnecting with an existing 48-in arched CMP just downstream of the easement break. UT1 Reach 2 UT1 Reach 2 begins downstream of the easement break at the culverted farm road crossing at Station 117+90. Enhancement level II activities were implemented along the reach. Construction activities were confined mostly to the upper portion of the reach and consisted of areas of bank grading, structure placement, and stream realignment to improve channel hydraulics and address areas of instability. The downstream section of Reach 2 flows through a series of abutting riparian wetlands was already mostly stable. Reach 2 ends at the easement break for the Elk Shoals Church Loop Road crossing at Station 130+46. UT1 Reach 3 Reach 3 begins just downstream of the Elk Shoals Church Loop Road crossing at Station 131+27. The reach is currently stable and exhibits mature vegetation; therefore, the channel was left undisturbed as a preservation reach. Desirable aquatic habitat is present throughout the reach and includes undercut banks, root mats, leaf packs, and small debris jams. Stabilizing the upstream reaches will allow for this reach to remain stable and reduce the sediment load. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 1-8 UT1 Reach 4A and 4B UT1 Reach 4A and 4B were designed as Rosgen C-type channels and improved through a combination of Priority 1 and Priority 2 restoration. Reach 4A begins at Station 138+28. Priority 2 restoration was implemented along the first 200 linear feet of reach to tie the channel with Reach 3, while Priority 1 was implemented along the remainder of the reach. Reach 4B begins at Station 152+59 where a step -pool conveyance best management practice (BMP) joins UT1 from the left floodplain. Priority 1 was also implemented along the majority of Reach 413; however, the restoration type was changed to Priority 2 along the last 100 feet of channel to its tie-in with the existing channel at Station 166+66. In -stream structures such as rock sills, log sills, constructed riffles, log j-hooks, brush toe, and cover logs were added for grade control, bank stability, and habitat creation. UT1A UT1A begins at Station 200+00 as an intermittent channel from a wetland seep. Enhancement II was implemented along the reach. While the channel will be raised to be connected to the existing floodplain, the stream alignment will not be changed. In -stream structures such as rock sills and constructed riffles were added for grade control and a variety of pool depths were incorporated for bedform diversity, energy dissipation, and aquatic habitat. A rock outlet enters the channel from a vernal pool located in the right floodplain. UT1A ends at Station 202+03 at its confluence with UT1 Reach 4A. No credit is being sought for this feature. Step -pool Conveyance (SPSC) BMP A step pool stormwater conveyance system was constructed within an ephemeral channel that flows into UT1 Reach 4B. The step pool system begins at Station 300+00 and conveys runoff from the adjacent pasture through a series of constructed riffles held by a rock sill and into a downstream pool. The reach acts as a stable conveyance to treat storm flows and dissipate storm velocities before its outlet into the main channel at Station 302+62. As with the other stream reaches throughout the Site, the riparian corridor of the BMP was planted with native vegetation, lies within the conservation easement, and was fenced to exclude cattle. No credit is being sought for this feature. 1.4 Project History, Contacts and Attribute Data The Site was restored by Wildlands through a Full Delivery contract with DIMS. Tables 2, 3, and 4 in Appendix 1 provide detailed information regarding the project activity and reporting history, project contacts, and project baseline information and attributes. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 1-9 Section 2.0 PERFORMANCE STANDARDS The stream performance criteria for the Site will follow approved performance criteria presented in the Alexander Farm Mitigation Site Mitigation Plan (2019) and is based on the performance criteria presented in the DIMS Stream and Wetland Mitigation Plan Template and Guidance (June 2017) and the NC IRT Wilmington District Stream and Wetland Compensatory Mitigation Update (10/24/2016). Annua monitoring and semi-annual site visits will be conducted to assess the condition of the finished project. Specific performance standard components are proposed for stream morphology, hydrology, and vegetation. Performance standards will be evaluated throughout the seven-year postconstruction monitoring period. The monitoring program designed to verify that performance standards are met is described in Section 3. 2.1 Streams 2.1.1 Dimension Riffle cross -sections on the restoration reaches should be stable and should show little change in bankfull area, bank height ratio, and width -to -depth ratio. All riffle cross -sections should fall within the parameters defined for the designated stream type. Bank height ratios shall not exceed 1.2 and entrenchment ratios shall be at least 1.4 for B-type channels and 2.2 for restored C-type channels. 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. Remedial action will not be taken if channel changes indicate a movement toward stability. 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. Remedial action would not be taken if channel changes indicate a movement toward stability. 2.1.2 Pattern and Profile A longitudinal profile was conducted as part of the as -built survey to provide a baseline for comparison should it become necessary to perform longitudinal profile surveys later during monitoring and to insure accordance with design plans. Annual longitudinal profile surveys are not required during the seven-year monitoring period unless other indicators during the annual monitoring indicate a trend toward vertical and lateral instability. If a longitudinal profile is deemed necessary, monitoring will follow standards as described in the 2016 USACE Stream and Wetland Mitigation Guidance for the necessary reaches. Restoration reaches must remain vertically stable throughout the monitoring period with little indication of downcutting or significant aggradation. Deposition of sediments at certain locations (such as the inside of meander bends) is expected and acceptable. Changes in pool depth are not an indication of vertical instability. Restoration reaches must remain laterally stable and major changes planform pattern dimensions and sinuosity should not occur. However, migration of meanders on alluvial channels is not an indication of instability if cross sectional dimensions continue to meet the requirements. 2.1.3 Substrate A pebble count was conducted at each surveyed riffle to characterize the pavement during the baseline monitoring only. A reach -wide pebble count will be performed in each restoration reach for monitoring years 1, 2, 3, 5 and 7. Reach -wide counts will be conducted for classification purposes. Restoration reaches should show maintenance of coarser materials in the riffle features and finer particles in the pool features. Riffles may fine over the course of monitoring due to the stabilization of contributing watershed sediment sources. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 2-1 2.1.4 Photo Documentation Photographs should illustrate the Site's vegetation and morphological stability on an annual basis. Cross- section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal photos should indicate the absence of persistent mid -channel bars or vertical incision. Grade control structures should remain stable. Deposition of sediment on the bank side of vane arms is preferable. Maintenance of scour pools on the channel side of vane arms is expected. 2.1.5 Hydrology Documentation The occurrence of bankfull events will be documented on restoration reaches throughout the monitoring period. Four bankfull flow events must be documented within the seven-year monitoring period. The four bankfull events must occur in separate years. Stream monitoring will continue until performance standards in the form of four bankfull events in separate years have been documented. 2.2 Vegetation The final vegetative success criteria will be the survival of 210 planted stems per acre in the riparian corridors at the end of the required monitoring period (MY7). The interim measure of vegetative success for the site will be the survival of at least 320 native species stems per acre at the end of the third monitoring year (MY3) and at least 260 stems per acre at the end of the fifth year of monitoring (MY5). In NC piedmont counties, planted trees must average 7 feet in height in each plot at the end of MY5 and 10 feet in height at Year 7. The extent of invasive species coverage will also be monitored and controlled as necessary throughout the required monitoring period. 2.3 Wetlands Wetland gages were installed within existing wetlands in areas along priority 1 restoration reaches to monitor groundwater hydrology, solely to verify the continuation of hydrologic wetland functions during the growing season. No wetland credits are being sought for this project and no performance criteria have been established. The NRCS Climate Analysis for Wetlands Tables (WETS) does not list a defined growing season for Alexander County due to insufficient data; therefore, the nearest WETS Station is Statesville 2 NNE (USDA, 2020) in Iredell County which is approximately 13.5 miles from the project site. The growing season based on data compiled from this WETS Station (1980 — 2020) is from April 4 through November 2 under typical precipitation conditions. 2.4 Visual Assessments Visual assessments should support the specific performance standards for each metric as described above. 2.5 Schedule and Reporting Monitoring reports will be prepared in the fall of each year of monitoring and submitted to DIMS. Based on the DIMS Annual Monitoring Report Format, Data Requirements, and Content Guidance (June 2017), the monitoring reports will include the following: • Project background which includes project objectives, project structure, restoration type and approach, location and setting, history and background, • Project Asset Map of major project elements, • Photographs showing views of the restored Site taken from fixed point stations, • CCPV Map with monitoring features and current problem areas noted such as stability and easement encroachment based on the cross-section surveys and annual visual assessments, • Assessment of the stability of the stream based on the cross -sections, • Vegetative data as described above including the identification of any invasion by undesirable plant species, Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 2-2 • A description of damage by animals or vandalism, • Maintenance issues and recommended remediation measures will be detailed and documented, and • Wildlife observations. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 2-3 Section 3.0 MONITORING PLAN & METHODOLOGY Annual monitoring will consist of collecting morphologic, vegetative, and hydrologic data to assess the project success based on the restoration goals, as outlined in the Alexander Farm Site Mitigation Plan (2019). Monitoring requirements will follow guidelines outlined in the DIMS Annual Monitoring Report Format, Data Requirements, and Content Guidance (June 2017) and the USACE Stream and Wetland Mitigation Guidance (October 2016). Installed monitoring device and plot locations closely mimic the locations of those proposed in the Site's Mitigation Plan. Deviations from these locations were made when professional judgement deemed them necessary to better represent as -built field conditions or when installation of the device in the proposed location was not physically feasible. Project success will be assessed by measuring channel dimension, substrate composition, vegetation, surface water hydrology, groundwater hydrology and by analyzing photographs and performing visual assessments. Any high priority problem areas identified, such as unstable stream banks, bed instability, aggradation/degradation, and/or poor vegetation establishment will be evaluated on a case -by -case basis. The problem areas will be visually noted and reported to DIMS staff in the annual report. Standard DIMS monitoring reports will be submitted in monitoring years 1, 2, 3, 5, and 7. Monitoring activities in years 4 and 6 will be documented in a memorandum to include a project summary update, annual photos, and updated monitoring plan map. Closeout will occur seven years beyond completion of construction or once performance standards are met. All survey data will be georeferenced to North Carolina State Plane coordinates. Refer to Table 5 in Appendix 1 for the monitoring component summary. 3.1 Streams Geomorphic assessments follow guidelines outlined in the Stream Channel Reference Sites: An Illustrated Guide to Field Techniques (Harrelson et al., 1994), methodologies utilized in the Rosgen stream assessment and classification documents (Rosgen, 1994 and 1996), and in the Stream Restoration: A Natural Channel Design Handbook (Doll et al., 2003). Please refer to Figures 3.0 through 3.3 in Appendix 1 for monitoring locations discussed below. 3.1.1 Dimension To assess channel dimension performance, 14 permanent cross -sections were installed along stream restoration reaches to represent approximately 50% riffles and 50% pools as defined in Table 15 of the Mitigation Plan. Cross-section locations were chosen in the field to be representative of the typical dimensions for each project reach. Each cross-section is permanently marked with rebar installed in concrete and % inch PVC pipes. Cross-section surveys will include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and thalweg. Cross-section surveys will be conducted in monitoring years one, two, three, five, and seven. Photographs will be taken of the cross -sections looking upstream and downstream during the survey assessment. 3.1.2 Pattern and Profile Longitudinal profile surveys will not be conducted during the seven-year post -construction monitoring period unless other indicators during the annual monitoring indicate a trend toward vertical and lateral instability. If a longitudinal profile is deemed necessary, monitoring will follow standards as described in the Stream Mitigation Guidelines issued in October 2016 by the NC IRT for the necessary reaches. Stream pattern and profile will be assessed visually as described below in Section 3.1.6. 3.1.3 Substrate Reach -wide pebble counts will be performed on each restoration reach for classification purposes only and will be conducted in monitoring years one, two, three, five, and seven. Riffle 100-count substrate sampling was collected in each surveyed riffle cross-section during the baseline monitoring only to characterize pavement at as -built. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 3-1 3.1.4 Photo Reference Points A total of 20 permanent photograph reference points were established along the stream reaches and the floodplain area after construction. Photographs will be taken once a year to visually document stability for the seven-year monitoring period. Permanent markers were established and located with GPS equipment so that the same locations and view directions on the site are photographed each year. Photos will be used to monitor all stream reaches. Longitudinal reference photos were established along the channel by taking a photo looking upstream and downstream. Cross -sectional photos will be taken of each permanent cross-section looking upstream and downstream. 3.1.5 Hydrology Documentation The occurrence of bankfull events will be documented throughout the seven-year monitoring period using pressure transducers, photographs, and visual assessments such as debris lines. Streamflow stage will be monitored using a continuous stage recorder (pressure transducer), referred to as a "crest gage" (CG). CGs were set to record bankfull events every three hours. One CG was installed along restoration reaches. The gage will be downloaded semi-annually to determine if a bankfull event has occurred. Photographs will be used to document the occurrence of debris lines and sediment deposition observed during field visits. The transducer data will be plotted and included in the annual monitoring reports. 3.1.6 Visual Assessment Visual assessments will be performed along stream reaches on a semi-annual basis during the seven- year monitoring period. Areas of concern, such as channel instability (i.e. lateral and/or vertical instability and in -stream structure failure, instability, and/or piping), poor vegetation health and/or establishment (i.e. low stem density, bare areas, high mortality rates, and/or invasive species), easement encroachment, beaver activity, and/or livestock trespass will be mapped, photographed, and described in the annual monitoring reports. Problem areas will be re-evaluated during each subsequent visual assessment. Should remedial actions be required, recommendations will be provided in the annual monitoring report. 3.2 Vegetation Vegetation monitoring quadrants (9 permanent and 3 mobile) were installed across the Site to measure the survival of the planted trees. Vegetative plot monitoring will occur between July 15Y and leaf drop during post -construction monitoring years 1, 2, 3, 5, and 7. Permanent plots will be monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008) and the 2016 USACE Stream and Wetland Mitigation Guidance to assess vegetative success. For both permanent and mobile plots, all woody stems, including exotic and invasive species, should be counted. Supplemental plantings and volunteer plants must be present for at least two growing seasons before counting toward performance standards for monitoring years five and seven. Exotic/invasive species will not count toward success of performance standards A total of 9 permanent vegetation plots were established within the project easement area. Permanent vegetation plots were randomly established within the planted stream riparian buffer areas to capture the heterogeneity of the designed vegetative communities. The locations of permanent vegetation plots were chosen using the same distribution throughout the planting areas, as shown in the Site's Mitigation Plan, and to best represent the planted areas within the easement. All of the permanent vegetative plots were established either as a standard 10-meter by 10-meter square plot or an optional 5-meter by 20-meter rectangular plot. The vegetation plot corners have been marked and are recoverable either through field identification or with the use of a GPS unit. Reference photographs were taken at the origin looking diagonally across the plot to the opposite corner during the MYO in April Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 3-2 2020. Subsequent assessments in monitoring years one, two, three, five, and seven following baseline survey will capture the same reference photograph locations. Beginning in MY1, individual permanent plot data will include diameter, height, density, vigor, damage (if any), and percent survival. Planted woody stems were marked and mapped in MYO and will be re -marked, if needed, during subsequent monitoring year assessments using a known origin so they can be found. Mortality will be determined from the difference between the baseline year's living planted stems and the current year's living planted stems. To evaluate random vegetation performance for the Site, 3 mobile vegetation plots were established in MYO, for use in MY1, using a circular or 100 m2 square/rectangular plot. Mobile plots will be re- established in different and random locations throughout the planted conservation easement in monitoring years 2, 3, 5, and 7. These locations will be geographically recorded and depicted in the CCPV maps for the corresponding monitoring assessment year. Mobile vegetation plot assessments will document the number of stems, number and type of species, and stem height within the plot. Please refer to Figures 3.0 through 3.3 in Appendix 1 for the permanent and mobile MYO/1 vegetation monitoring plot locations. 3.3 Wetlands To monitor the existing wetlands during post -construction monitoring, two groundwater monitoring gages were installed in April 2020 per USACE recommended procedures within the wetland areas using In- situ Level TROLL® 100 pressure transducers. The locations of the installed gages closely mimic those of the Site's Mitigation Plan. Minor adjustments in these locations were made to best represent wetland topography as needed. The groundwater gages are set to record the groundwater level four times per day and will be downloaded during site visits. The locations of the groundwater gages are denoted in Figures 3.0 through 3.3 in Appendix 1. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 3-3 Section 4.0 ADAPTIVE MANAGEMENT AND CONTINGENCY PLAN 4.1 Adaptive Management Plan Wildlands will perform maintenance as needed on the mitigation project. A physical inspection of the Site shall be conducted a minimum of once per year throughout the post -construction monitoring period or until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance for stream features should be most often expected in the first two years following site construction. The need for maintenance will be evaluated annually during monitoring activities. Maintenance may include the following activities. Component/ Maintenance through project close-out Feature Routine channel maintenance and repair activities may include chinking of in -stream structures to prevent piping, securing of loose coir matting, and supplemental installations of live stakes and other target vegetation along the channel — these shall be conducted where success criteria are threatened or at the discretion of the Designer. Areas where Stream storm water and floodplain flows intercept the channel may also require maintenance to prevent bank failures and head -cutting. Beaver activity will be monitored and beaver dams on project streams will typically be removed, at the discretion of the Designer, during the monitoring period to allow for bank stabilization and stream development outside of this type of influence. BMP Routine BMP Maintenance and repair activities may include chinking of BMP structures to prevent piping and securing of loose coir fiber matting. Vegetation shall be maintained to ensure the health and vigor of the targeted community. Routine vegetation maintenance and repair activities may include supplemental planting, Vegetation pruning, mulching, and fertilizing. Exotic invasive plant species treatment will be conducted per the Invasive Species Treatment Plan, outlined in Appendix 6 of the Alexander Farms Mitigation Plan (2019), and in accordance with NC Department of Agriculture (NCDA) rules and regulations. Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries may be identified by fence, marker, Site Boundary bollard, post, tree -blazing, or other means as allowed by site conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as -needed basis. The Wildlands Team will develop necessary adaptive measures or implement appropriate remedial actions in the event that the Site or a specific component of the Site fails to achieve the success criteria outlined above. The project -specific monitoring plan developed during the design phase identifies an appropriate threshold for maintenance intervention based on the monitored items. Any actions implemented will be designed to achieve the success criteria specified previously and will include a work schedule and updated monitoring criteria. If, during annual monitoring it is determined the Site's ability to achieve Site performance standards are jeopardized, Wildlands will notify the members of the DIMS and work with them to develop contingency plans and remedial actions. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 4-1 Section 5.0 AS -BUILT CONDITION (BASELINE) The Site construction and planting were completed by April 17, 2020. The as -built survey, which included developing an as -built topographic surface and locating the channel boundaries, structures, and cross -sections were completed by May 16, 2020. Installation of monitoring features and the collection of sediment and vegetative data were completed by April 29t", 2020. However due to the lack of leaf -out on some of the bare roots within the vegetative plots, it was determined during data processing that some of the planted species were mis-identified. Therefore, vegetation plots species were verified on June 8, 2020. Fencing installation was completed and surveyed in July 2020. 5.1 Record Drawings A sealed half-size record drawing is located in Appendix 4 and includes redlines for any significant field adjustments made during construction that were different from the design plans.

Changes to the as -built planting list were made to account for the species availability at the time of planting. Changes in the location of bare root plantings were adjusted as needed along the top of bank in the areas where channel realignment was conducted. Specific changes to the plant species lists are outlined below. Open/Graded Buffer Planting Zone — • The following bareroot species were removed from the planting list due to the lack of available species at the time of planting: Swamp chestnut oak (Quercus michauxii). • The following species were added to the planting list to increase species diversity at the direction of the engineer: White Oak (Quercus alba) and Northern Red Oak (Quercus rubra). • The remaining species' "Percent of Stems" were adjusted accordingly. Shaded Area Buffer Planting Zone — • The following bareroot species were removed from the planting list due to the lack of available species at the time of planting: Swamp chestnut oak (Quercus michauxii), beautyberry (Callicarpa americana), American strawberry bush (Euonymus americanus), and sweetshrub (Calycanthus floridus). Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 5-2 • The following species were added to the planting list to increase species diversity at the direction of the engineer: White Oak (Quercus alba). The remaining species' "Percent of Stems" were adjusted accordingly. Streambank Planting Zone — • Percent planting for silky dogwood (Cornus amomum) and silky willow (Salixsericea) were adjusted from 40% to 36% and from 40% to 44%, respectively. Vernal Pool and Wetland Planting Zone — • The following herbaceous species were removed from the planting list due to the lack of available species at the time of planting: Broadwing sedge (Carex alata) and Bluejoint grass (Calamagrostis canadensis). The following species were added to the herbaceous planting list to increase species diversity at the direction of the engineer: Fringed sedge (Caryx crinata) and bushy beardgrass (Andropogon glomeratus). The remaining species' "Percent of Stems" were adjusted accordingly. 5.2 Baseline Data Assessment MYO was conducted between April and June 2020. Cross-section and longitudinal profile data collection were completed by May 16, 2020. The collection of sediment and vegetative data were completed by April 29t" 2020, and vegetative species identification was verified in early June 2020. Locations of the monitoring features are depicted in Figures 3.0 through 3.3 in Appendix 1. The first annual monitoring assessment (MY1) will be completed in the fall of 2020. The streams will be monitored for a total of seven years, with the final monitoring activities scheduled for 2026. 5.2.1 Morphological State of the Channel Please refer to Appendix 2 for summary data tables, morphological plots, and stream photographs. Profile The MYO profiles generally match the profile design parameters. As -built riffle slopes calculated for UT1 RIB resulted in a greater variation in range than those of design; however, the overall channel slope was similar to design parameters and on -site as -built reviews showed no visual indicators of vertically instability. Variations from the design profile often reflect field changes during construction as a result of field conditions and do not constitute a problem or indicate a need for remedial actions. Channels profiles will continue to be assessed visually during the CCPV Site walks. Dimension The MYO dimension numbers closely match the design parameters with minor variations. The maximum bankfull width for UT1 Reach 4A slightly exceeds design parameters; however, channels are likely to narrow over time as vegetation is established. This narrowing over time would not be an indicator of instability in and of itself. On -site as -built reviews showed no visual indicators of lateral instability. Pattern The MYO pattern metrics fell within acceptable ranges of the design parameters. Substrate Reach -wide pebble counts were performed on each restoration reach to establish stream classification at baseline conditions, and riffle 100-count substrate sampling was collected at each surveyed riffle cross- section to characterize pavement at as -built. Sediment analysis results were similar to design parameters; however, some reaches and cross -sections exhibited slightly coarser substrate than designed. These variations immediately after construction are normal because coarser materials are Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 5-3 used to provide immediate grade control on the newly constructed channel. Over time, the channel will continue to move gravels and finer sediments into the system creating a mix of coarse substrate in the riffles and fine sediments in the pools. On -site as -built reviews showed no visual indicators of instability within riffle or pools. Bankfull Events Bankfull events recorded following completion of construction will be reported in the Year 1 monitoring report. 5.2.2 Vegetation The overall MYO planted density is 499 stems/acre for permanent vegetation plots and 526 stems/acre for mobile vegetation plots. The total overall planted Site mean density is 506 stems/acre, which exceeds the interim measure of vegetative success of at least 320 planted stems per acre required atthe end of the third monitoring year. Summary data and photographs of each plot can be found in Appendix 3. 5.2.3 Wetlands Groundwater gage data will be reported in the annual MY1 report. Alexander Farm Mitigation Site As -Built Baseline Monitoring Report 5-4 Section 6.0 CREDIT RELEASE SCHEDULE All credit releases will be based on the total credit generated as reported by the as -built survey of the mitigation site. Under no circumstances shall any mitigation project be debited until the necessary Department of the Army (DA) authorization has been received for its construction or the District Engineer (DE) has otherwise provided written approval for the project in the case where no DA authorization is required for construction of the mitigation project. The DE, in consultation with the Interagency Review Team (IRT), will determine if performance standards have been satisfied sufficiently to meet the requirements of the release schedules below. In cases where some performance standards have not been met, credits may still be released depending on the specifics of the case. Monitoring may be required to restart or be extended, depending on the extent to which the site fails to meet the specified performance standard. The release of project credits will be subject to the criteria described as follows: Table A: Credit Release Schedule —Stream Credits —Alexander Farms Mitigation Site Credit ILF/NCDMS Release Release Activity Interim Total Milestone Release Released Completion of all initial physical and biological improvements made 2* pursuant to the Mitigation Plan. 30% 30% First year monitoring report demonstrates that channels are stable interim 3 performance standards are being met. 10% 40% Second year monitoring report demonstrates that channels are stable 4 interim performance standards are being met. 10% 50% Third year monitoring report demonstrates that channels are stable 5 10% 60% interim performance standards are being met. Fourth year monitoring report demonstrates that channels are stable 65% 6** 5% interim performance standards are being met. (75%***) Fifth year monitoring report demonstrates that channels are stable interim 75% 7 performance standards are being met. 10% (85%***) Sixth year monitoring report demonstrates that channels are stable 80% 8** 50� interim performance standards are being met. (90%***) Seventh year monitoring report demonstrates that channels are stable 9 performance standards have been met and project has received closeout 10% 90% (100%***) approval. *For ILF sites (including all NCDMS projects), no initial release of credits (Milestone 1) is provided because ILF programs utilized advance credits, so no initial release is necessary to help fund site construction. To account for this, the 15% credit release associated with the first milestone (bank establishment) is held until the second milestone, so that the total credits release at the second milestone is 30%. In order for NCDMS to receive the 30% release (shown in the schedules as Milestone 2), they must comply with the credit release requirements stated in Section IV(I)(3) of the approved NCDMS Instrument. **Please note that vegetation data may not be required with monitoring reports submitted during these monitoring years unless otherwise required by the Mitigation Plan or directed by the NCIRT. ***10% reserve of credits to be held back until the bankfull event performance standard has been met.

Cross -sections were permanently marked with rebar to establish location. Surveys include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and thalweg. 2. Pattern and profile will be assessed visually during semi-annual site visits. Longitudinal profile was collected during the as -built baseline monitoring survey only, unless observations indicate widespread lack of vertical stability (greater than 10% of reach is affected) and profile survey is warranted in additional years to monitor adjustments or survey repair work. 3. Riffle 100-count substrate sampling were collected during the baseline monitoring only. A reach -wide pebble count will be performed on each restoration or enhancement I reach each year for classification purposes. 4. Crest gages and/or transducers will be inspected and downloaded quarterly or semi-annually. Evidence of bankfull events such as rack lines or floodplain deposition will be documented with a photo when possible. Transducers, if used, will be set to record stage once every three hours. 5. Permanent vegetation monitoring plot assessments will follow CVS Level 2 protocols. Mobile vegetation monitoring plot assessments will document number of planted stems, height, and species using a circular or 100 m2 square/rectangular plot. 6. Locations of exotic and nuisance vegetation will be mapped. 7. Locations of vegetation damage, boundary encroachments, etc. will be mapped. 8. Wetland gages were installed within existing wetlands located where Priority 1 restoration was conducted to monitor groundwater hydrology. No wetland credits are being sought for this project and no performance criteria have been established. k &V WILDLANDS ENGINEERING MEETING NOTES MEETING: Post -Contract IRT Site Walk ALEXANDER FARM Mitigation Site Catawba 03050101; Alexander County, NC DEQ Contract No. 7416 DMS Project No. 100048 Wildlands Project No. 005-02169 DATE: Thursday, March 29, 2018 LOCATION: Elk Shoals Church Loop Stony Point, NC Attendees Steve Kichefski, USACE Harry Tsomides, DMS Mac Haupt, DWR Olivia Munzer, WRC Kirsten Ullman, DMS Shawn Wilkerson, Wildlands Todd Bowers, EPA Alan Johnson, DWR Christine Blackwelder, Wildlands Paul Wiesner, DMS Ori Tuvia, DWR Materials • Wildlands Engineering Technical Proposal dated 9/21/2017 in response to DMS RFP 16-007277 Meeting Notes The meeting began at 1 pm. Shawn presented an overview of the project at the parking location. From there, the group walked upstream to the headwaters of UT1, retraced steps and reviewed UT1 downstream of the road, UT1A, and the potential wetland area in the left floodplain at the downstream site extents. The meeting concluded at 3:30 PM. 1. Overall project comments • Bald eagle is listed for Alexander County. No bald eagle nest noticed in vicinity, nor is there a record adjacent to the site. • Alexander family house (historical) located near the site. • Olivia recommends that no trees are cleared during bat maternity roosting period (June/July). 2. Potential Wetland Credit Areas Steve noted that if wetlands are included in the project, he or William Elliott (USACE) will do a more thorough review of the site when they return for the jurisdictional determination. ALEXANDER FARM Mitigation Site — IRT Meeting Notes • Upstream of road o There area few wetland pockets in the right floodplain just upstream of the road, and several more in the left floodplain upstream of the proposed stream crossing. o Steve asked that wetland pockets be encompassed by the easement, even if not for credit. • Downstream of road o If needed, the area in the left floodplain that is currently ditched has potential for wetland credits. o Discussion about the need to drop a well into any wetland proposed for restoration credit to begin pre -construction data collection asap. 3. Stream Restoration • Upstream of the road o The group walked up to the head of UT1. Cattle have been rotated out of this pasture and are in the pasture downstream of the road. o The start of UT1 is a large cattle wallow area. Shawn discussed that Wildlands may install a BMP to treat concentrated agricultural runoff above the reach. o Mac noted the soils at the head of UT1 and that this area may have been a wetland before the headcut advanced through and formed a stream channel. o Several members of the group noted that UT1 here has a lot of side seeps and noted areas of channel recovery from the absence of cattle over the last few months. One area of UT1 here just upstream of a headcut has very low banks and the group discussed tying design into this area. Shawn noted the planar bed and lack of habitat but did agree that Wildlands may utilize good areas of existing channel in the restoration design. o Continuing downstream, Olivia expressed concern over how close the proposed crossing is to the existing left floodplain wetland. The valley walls are relatively steep near the proposed crossing, and Wildlands will likely shift this crossing further downstream to where crossing will be easier for the farmer, which should also address any wetland concerns. o The crossing shown in the proposal marks a transition from restoration upstream to enhancement 2 downstream, although the group agreed that there isn't a clearly defined transition point in the field. The proposed enhancement 2 section will require some areas of restoration or enhancement I, and some of the restoration area may be fine with a lighter touch. o Overall, upstream of the road, the group discussed restoration at 1:1 credit from the head of the channel down to the existing fence line, and enhancement 2 at 2:1 credit from the fence line to the road. This would shorten the proposed restoration footage in this area by approximately 400 feet. • Downstream of the road o Within the woods, the group generally agreed with a preservation approach. At the headcut which marked the proposed transition from preservation to restoration, the group agreed that a transitional length of enhancement 2 was appropriate. This transitional length will continue until the stream enters the active cattle pasture, where the approach will switch to restoration down to the end of the project. Wildlands Engineering, Inc. page 2 ALEXANDER FARM Mitigation Site Post -Contract IRT Site Walk ALEXANDER FARM Mitigation Site — IRT Meeting Notes o The restoration downstream of the road was presented in the proposal at 1.5:1 credit due to the amount of floodplain vegetation which had established in absence of the cattle over the last two years. The group noted the extreme difference in the floodplain vegetation and channel condition since the cattle have been rotated back into the field, and that the reach is worthy of traditional 1:1 crediting. o Olivia noted underground flow from the left floodplain near the downstream project extent. These may be drain tiles from the field. Wildlands will review this more carefully during the existing conditions assessment. These meeting minutes were prepared by Christine Blackwelder and reviewed by Shawn Wilkerson on April 13, 2018, and represent the authors' interpretation of events. Olivia Munzer comments (May 7, 2018) were incorporated on May 15, 2018. These minutes are now final. Wildlands Engineering, Inc. page 3 ALEXANDER FARM Mitigation Site Post -Contract IRT Site Walk k &V WILDLANDS ENGINEERING MEMO REGARDING: Credit Ratios ALEXANDER FARM Mitigation Site Catawba 03050101; Alexander County, NC DEQ Contract No. 7416 DMS Project No. 100048 Wildlands Project No. 005-02169 DATE: Monday, April 16, 2018 In the September 26, 2017, Technical Proposal for the Alexander Farm Mitigation Site, Wildlands presented various credit ratios for UT1 upstream and downstream of Elk Shoals Church Loop road based on the channel conditions at the time of the proposal. This memo reflects changes to the proposed credit ratios in response to discussion during the IRT field walk of the site on March 29, 2018. Upstream of the road The stream crossing shown in the proposal marked the proposed transition from restoration at 1:1 credit to enhancement 2 at 2.5:1 credit; however, during the IRT field walk, the group agreed that there isn't a clearly defined transition point in the field. The proposed enhancement 2 section will require some areas of restoration or enhancement I, and some of the restoration area may be fine with a lighter touch. The IRT group discussed restoration at 1:1 credit from the head of the channel down to the existing fence line (which crosses the channel upstream of the stream crossing), and enhancement 2 at 2:1 credit from the fence line to the road. This would shorten the restoration footage presented in the proposal in this area by approximately 400 feet. After the meeting, Wildlands reviewed the contracted credit requirements, and given the large area of transition from restoration to enhancement 2 upstream of the road, Wildlands will likely propose the entire area upstream of the road as enhancement 2 at 2:1 credit in the mitigation plan and apply the appropriate level of intervention needed throughout the reach. Downstream of the road Within the woods, the IRT group generally agreed with the preservation approach presented in the proposal. At the headcut which marked the proposed transition from preservation to restoration, the group agreed that a transitional length of enhancement 2 was appropriate. This transitional length will continue until the stream enters the active cattle pasture, where the approach will switch to restoration down to the end of the project. The Alexander Farm tenant farmer rotates his 175-head herd between the pasture upstream of the road in spring and summer and the downstream of the road in fall and winter. Wildlands visited the Site several times between 2010 and 2015 and confirmed this land management practice. Over the 2 years prior to submittal of the proposal, however, the tenant farmer kept the herd upstream of the road to allow for fencing repair and ALEXANDER FARM Mitigation Site —Credit Memo replacement downstream of the road. During this time, he cut hay downstream of the road, but allowed the riparian area to grow with annuals. During the proposal process, the farmer told Wildlands that his repairs would soon be complete and he would then move the herd downstream of the road. Despite incision throughout the channel length, Wildlands proposed a lower credit ratio of 1.5:1 for restoration downstream of the road to acknowledge the reach's heavy herbaceous cover due to the absence of recent cattle activity. The farmer completed his fencing repairs after the proposal was submitted and moved his herd downstream of the road. During the IRT site walk on March 29, 2018, the IRT group noted that all the riparian vegetation was gone and impacted by cattle. IRT members, Wildlands, and DMS all felt that the restoration activities proposed downstream of the road were now creditable at a 1:1 ratio. Wildlands proposes this section of restoration at 1:1 credit. Please see the attached figure which illustrates the proposed shift in credit ratios. All proposed credit ratios will be fully justified in the mitigation plan.
