The Foust Creek Mitigation Site (Site) proposes to provide 4,770 Stream Mitigation Units (SMUs) and 3.91 Wetland Mitigation Units (WMUs). The project consists of Foust Creek, a second order perennial stream, and an unnamed, intermittent first order tributary to Foust Creek (UT1). At the downstream limits of the project the drainage area is 1,259 acres (1.97 square miles). The Site is located in the southern portion of Alamance County, east of Snow Camp and approximately 15 miles southeast of the City of Burlington (Figure 1). It is located in the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998). The Site is in the Jordan Lake Water Supply Watershed within the North Carolina Division of Water Resources (NCDWR) subbasin 03-06-04 of the Cape Fear River Basin and United States Geological Survey (USGS) Hydrologic Unit 03030002050050. Prior to construction activities, both streams had been degraded by livestock access and agricultural practices. The primary objectives of the project were to promote wetland hydrology; restore a stream and wetland complex to mimic a naturally occurring ecosystem; restore a stream system to promote hydrologic connectivity with the floodplains and wetlands; stabilize stream banks; promote instream habitat and aeration; restore riparian buffers; and further improve water quality through removing existing agricultural practices. Figure 2 and Table 1 present the restoration and enhancement components/assets for the Site. The following project goals were established to address the effects listed above from watershed and project site stressors: • Reduce sediment inputs by removing cattle from streams and restoring degraded and eroding stream channels; • Return a network of streams to a stable form that is capable of supporting biological functions; • Reduce fecal coliform, nitrogen, and phosphorus inputs through removing cattle from streams and establishing and augmenting a forested riparian corridor; and • Protect existing high quality streams and forested buffers. Stream and wetland restoration and enhancement construction efforts were completed in February 2015. Baseline as -built monitoring activities (MYO) were completed in February 2015. A conservation easement is in place on 22.11 acres of the stream and wetland riparian corridors to protect them in perpetuity. Monitoring Year 4 (MY4) site visits and assessments were completed between the March and October 2018 to visually assess the conditions of the project and collect stream and wetland hydrology data. Per North Carolina Interagency Review Team (NCIRT) guidelines, detailed monitoring and analysis of vegetation, substrate, and channel cross-sectional dimensions did not occur during MY4. Visual observations, hydrology data, and management practices are included in this report. To preserve the clarity and continuity of reporting structure, this report maintains section and appendix numbering from previous monitoring reports. Omitted sections are denoted in the table of contents. Overall, Site performance for vegetation, stream geomorphology, and hydrology meet success criteria for MY4. Vegetation appears to be performing adequately to attain the interim success criteria of 260 stems per acre at the end of monitoring year five. Visual observation indicated that stream channels have remained geomorphically stable during MY4. Persistent flows and multiple bankfull events were recorded on both Foust Creek and UT1. All nine groundwater wells met the success criteria of Foust Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL iii maintaining a free water surface within 12 inches of the soil surface for 8.5 percent of the growing season. Identified invasive vegetation has been treated.

The Site is located upstream and downstream of the Snow Camp Road stream crossing immediately east of the town of Snow Camp. The Site is located in the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998). The project watershed consists primarily of agricultural lands and forest. The drainage area for the project site is 1,259 acres (1.97 square miles) at the lower end of Foust Creek. The project stream reaches include Foust Creek and UTI and were improved through stream restoration and enhancement level II approaches. Mitigation work within the Site included restoration and enhancement of 5,500 linear feet (LF) of perennial and intermittent stream channel and rehabilitation and re-establishment of 4.96 acres (ac) of riparian wetland. The stream and wetland areas were also planted with native vegetation to improve habitat and protect water quality. The Site proposes to provide 4,770 Stream Mitigation Units (SMUs) and 3.91 Wetland Mitigation Units (WMUs). The final Mitigation Plan (Wildlands, 2014) was submitted and accepted by the North Carolina Department of Environmental Quality, Division of Mitigation Services (DMS) in February of 2014. Construction activities were completed by Fluvial Solutions in February 2015. The planting was completed by Bruton Natural Systems, Inc. in February 2015 and baseline monitoring (MYO) was conducted in January and February 2015. Annual monitoring will be conducted for seven years with the close-out anticipated to commence in 2022 given the success criteria are met. Appendix 1 provides more detailed project activity, history, contact information, and watershed/site background information for this project. A conservation easement has been recorded and is in place along the stream and wetland riparian corridors to protect them in perpetuity; ac (Deed Book 3278, Pages 935-944) within four parcels. Directions and a map of the Site are provided in Figure 1 and project components are illustrated in Figure 2. 1.1 Project Goals and Objectives Prior to construction activities, both streams had been degraded by livestock access and agricultural practices. Impacts to the stream included direct access by livestock, trampling of the riparian vegetation and stream banks, channelization, eroding banks, floodplain ditching, and a lack of stabilizing riparian vegetation. The adjacent floodplain had been cleared for pasture and was grazed by livestock. The riparian vegetation was either absent, limited to the streambanks, or periodically disturbed. Table 4 in Appendix 1 presents the pre -restoration conditions in detail. The Site was designed to meet the over -arching goals as described in the Mitigation Plan (Wildlands, 2014). The project is intended to provide numerous ecological benefits within the Cape Fear River Basin. While many of these benefits are limited to the Site, others, such as pollutant removal and improved aquatic and terrestrial habitat, have farther reaching effects. The following project specific goals established in the Mitigation Plan (Wildlands, 2014) include: • Reduce sediment inputs by removing cattle from streams and restoring degraded and eroding stream channels; • Return a network of streams to a stable form that is capable of supporting biological functions; • Reduce fecal coliform, nitrogen, and phosphorus inputs through removing cattle from streams and establishing and augmenting a forested riparian corridor; and • Protect existing high quality streams and forested buffers. Foust Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL 1-1 The project goals were addressed through the following project objectives: • On-site nutrient inputs were decreased by removing cattle from streams, re-establishing floodplain connectivity, and filtering on-site runoff through buffer zones and wetlands. Off- site nutrient input is absorbed on-site by filtering flood flows through restored floodplain areas and riparian wetlands, where flood flow spreads through native vegetation. Vegetation uptakes excess nutrients. Stream bank erosion which contributes sediment load to the creeks was greatly reduced in the project area. Eroding stream banks were stabilized using bioengineering, natural channel design techniques, and grading to reduce bank angles and bank height. Storm flow containing grit and fine sediment is filtered through restored floodplain areas, where flow spreads through native vegetation. Spreading flood flows also reduce velocity and allow sediment to settle out. Sediment transport capacity of restored reaches was improved so that capacity balances more closely to load. Sediment load reduction will be monitored through assessing bank stability with cross section surveys and visual assessment through photo documentation which serves as an accepted surrogate for direct turbidity measurements. • Restored riffle/pool sequences promote aeration of water and create deep water zones, helping to lower water temperature. Establishment and maintenance of riparian buffers creates long-term shading of the channel flow to minimize thermal heating. Lower water temperatures help maintain dissolved oxygen concentrations. • In -stream structures were constructed to improve habitat diversity and trap detritus. Wood habitat structures were included in the stream as part of the restoration design. Such structures included log drops and rock structures that incorporate woody debris. • Adjacent buffer and riparian habitats were restored with native vegetation as part of the project. Native vegetation provides cover and food for terrestrial creatures. Native plant species were planted and invasive species were treated. Eroding and unstable areas were also stabilized with vegetation as part of this project. • The restored land is protected in perpetuity through a conservation easement. The design streams and wetlands were restored to the appropriate type based on the surrounding landscape, climate, and natural vegetation communities but also with strong consideration to existing watershed conditions and trajectory. Specifically, the Site design was developed to restore a stream and wetland complex to mimic a naturally occurring ecosystem creating riparian habitat and improving water quality. 1.2 Monitoring Year 4 Data Assessment Annual monitoring and quarterly site visits were conducted during monitoring year 4 (MY4) to visually assess the condition of the project and collect hydrology data. Per NCIRT guidelines, detailed monitoring and analysis of vegetation, substrate, and channel cross-sectional dimensions did not occur during MY4. 1.2.1 Vegetative Assessment Detailed vegetation inventory and analysis is not required during MY4. Visual assessment during MY4 indicated that vegetation is performing adequately to attain interim success criteria of 260 planted stems per acre at the end of MY5 and terminal success criteria of 210 planted stems per acre averaging ten feet in height. Foust Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL 1-2 1.2.2 Vegetation Areas of Concern Concentrated populations of Chinese privet (Ligustrum sinense), tree of heaven (Ailanthus altissima), and autumn olive (Eleagnus umbellata) were observed during MY4 (Figure 3.1, Figure 3.3). The autumn olive and tree of heaven populations were located adjacent to Foust Creek Reach 1. The Chinese privet population consisted of re -sprouts from a previous treatment located in the northwestern portion of the easement adjacent to Foust Creek Reach 3b. Stems of autumn olive and Chinese privet larger than one inch in diameter were treated with triclopyr or glyphosate, respectively, using the cut stump method. Stems smaller than one inch in diameter were treated via foliar application of the same respective herbicides. Tree of heaven was treated with triclopyr using the hack and squirt method. All treatment occurred during September 2018. 1.2.3 Stream Assessment Detailed dimensional survey and analysis is not required during MY4. Visual monitoring indicated that the stream channel is performing as designed. No deposition or erosion exceeding approximate natural levels or indicators of channel instability were observed. 1.2.4 Stream Areas of Concern During October of MY4, beaver dams were observed in Foust Creek Reach 2 (Figure 3.1, Figure 3.2). The USDA has been contracted to remove the beaver and clear the dams from the stream. 1.2.5 Hydrology Assessment At the end of the MY7, two or more bankfull events must have occurred in separate years within the restoration reaches. Multiple bankfull events were recorded on both Foust Creek and UTI with automated crest gages during MY4 data collection. Both Foust Creek and UT1 recorded bankfull events during MY1, MY2, MY3, and MY4 (Table 13); therefore the Site has met the bankfull frequency success criteria for the seven year monitoring period. A pressure transducer was installed on UTI to monitor flow within UT1 to document jurisdictional status. Baseflow must be present for at least some portion of the year (most likely in the winter/early spring) during years with normal rainfall conditions. A gage malfunction occurred from October 26, 2017 through March 20, 2018. Based on previous years data, it is likely that the stream flowed continuously during this period in which the gage malfunctioned. Of recorded data, persistent flow occurred until mid-June (flow recorded 98 out of 101 days). Flow was recorded for a maximum of 53 consecutive days and a total of 164 days as of October 25, 2018. Therefore, UT1 has met the flow duration success criteria for MY4. Refer to Appendix 5 for hydrologic data. 1.2.6 Wetland Assessment Nine groundwater gages are monitored within the wetland rehabilitation and re-establishment zones. All gages were installed at appropriate locations such that the data collected provides an indication of groundwater levels throughout the Site. To determine the growing season at the Site, one soil temperature probe was installed. A barometric pressure logging device was also installed to allow calculation of groundwater depths. All monitoring gages were downloaded and maintained as needed. The success criteria for wetland hydrology is a free groundwater surface within 12 inches of the soil surface for 8.5 percent of the growing season, which is measured in consecutive days under normal precipitation conditions. During MY1 NRCS WETS Data was used to determine the growing season for the Site. After discussions with the United States Army Corps of Engineers (USACE), it was agreed to use on-site soil temperature data to determine the beginning of the growing season and use NRCS WETS data to determine the end of the growing season. The soil temperature probe is used to determine the Foust Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL 1-3 beginning of the growing season based on soil temperatures staying above 41 degrees Fahrenheit at 12 inches below the soil surface. Refer to Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology data and plots. All nine groundwater gages met success criteria during 1MY4, exceeding the 8.5 percent criteria level by at least 4.3 percent. Consecutive percentages of the growing season during which the water table was at or above a soil depth of 12 inches range from 12.8 percent to 93.3 percent. Groundwater gage 5 malfunctioned from July 6, 2018 until it was repaired on October 31, 2018. The entire growing season was not observed since all gages easily satisfied criteria prior to the end of the growing season. 1.2.7 Maintenance Plan The invasive species populations described above in section 1.2.2 will continue to be monitored and treated as necessary. Beaver will be removed from the Site and streams will be monitored for any beaver activity in subsequent monitoring years. 1.3 Monitoring Year 4 Summary Visual assessment indicated that all stream reaches within the Site are geomorphically stable and functioning as designed. Survival and growth of planted trees appear to be on track meet interim success criteria. Invasive vegetation identified to date has been treated. Stream hydrology criteria for flow duration were met for MY4, and bankfull event frequency criteria have been satisfied for the duration of the monitoring period. All wetland areas met groundwater hydroperiod criteria for MY4. The Site is on track to meet success criteria for closeout in 2022. Foust Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL 1-4 Section 2: METHODOLOGY All data collected for the Integrated Current Condition Mapping was recorded using a Trimble handheld GPS with sub -meter accuracy and processed using Pathfinder and ArcGIS software. Crest gages and pressure transducers were installed in surveyed riffle cross sections and monitored quarterly.
