Documentation of Geomorphically Significant Flow Events Dairyland Flow Gauge UT2 Stream Flow Hydrograph 1.0 Proiect Summary L I Project Location and Description The Dairyland Stream Mitigation Site (the "Site") is located within a watershed dominated by agricultural and residential land use in Orange County, North Carolina, about eight miles Southwest of Hillsborough. The project area exhibited diminished hydrology and habitat value as a result of past and on -going agricultural activities. The project involved the restoration, enhancement, and protection of streams in the Cape Fear River basin. The project lies within the Haw River Basin and Jordan Lake Watershed (8-digit USGS HUC 03030002, 14-digit USGS 03030002050030). The project watershed is primarily characterized by agriculture, forests, and low -intensity residential areas. The total easement area is 28.6 acres. Adjacent fields are dominated by corn and soybeans. Vegetation around the ponds and the unbuffered stream reaches (HB1, HB2, and UT2) was primarily composed of herbaceous vegetation and scattered trees. The existing farm ponds offered little habitat to support aquatic life, and the riparian buffers were not maximizing their potential to filter nutrients. The Site will be monitored on a regular basis and a physical inspection of the site will be conducted at a minimum of twice per year throughout the seven-year post -construction monitoring period, or until performance standards are met. These site inspections will identify site components and features that require routine maintenance. The measure of stream restoration success will be documented by bankfull flows and no change in stream channel classification. The measure of vegetative success for the site will be the survival of at least 210 seven-year old planted trees per acre at the end of year seven of the monitoring period. Upon approval for closeout by the Interagency Review Team (IRT), the site will be transferred to Unique Places to Save (UP2S), an approved third -party long-term steward. The long-term steward will be responsible for periodic inspection of the site to ensure that restrictions required in the Conservation Easement, or the deed restriction document(s) are upheld. Easements will be stewarded in general accordance with the guidelines published by the National Land Trust Alliance. These guidelines include annual monitoring visits to easements and related communication with the landowner(s). 1.2 Project Goals and Objectives The North Carolina Division of Mitigation Services (DMS) develops River Basin Restoration Priorities (RBRP) to guide its restoration activities within each of the state's 54 hydrologic units. The 2009 Cape River Basin RBRP identified several restoration needs for the entire Cape River Basin, as well as for hydrologic unit code (HUC 03030002), specifically. To satisfy these needs RES has established the RES Cape Fear 02 Umbrella Mitigation Bank, with the first approved bank site being the Dairyland Mitigation Site. The Site is located within the Haw River, the major river in HUC 03030002. This river and its tributaries flow to B. Everett Jordan Lake, a drinking water supply. This supply has been designated a Nutrient Sensitive Water and NC Division of Water Resources (DWR) has developed a set of goals to reduce non - point source pollution in its watershed. Goals include promoting nutrient and sediment reduction in agricultural and urban areas by restoring and preserving streams, wetlands, and riparian buffers. The Site provides compensatory mitigation for impacts on the Waters of the US under the Section 404 of the Clean Water Act. Dairyland 1 Year 3 Monitoring Report Stream Mitigation Site October 2021 Project goals will be addressed through the following project objectives: • Dam breach and pond removal, • Restoration of appropriate pattern, dimension, and profile in stream channels. • Restoration of forested riparian stream buffers, • Enhancement of hydrology and vegetation in existing riparian wetlands, • Treatment and control of exotic invasive species, • Stabilization of eroding stream banks due to lack of vegetation, and • Addition of large woody debris, such as log vanes, log weirs, root wads. Due to its location and improvements, the Site provides numerous ecological and water quality benefits within the Cape Fear River Basin. While many of these benefits are limited to the project area, others, such as pollutant removal and improved aquatic and terrestrial habitat, have farther -reaching effects. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations, improvement of terrestrial habitat, and construction of in -stream structures, address the degraded water quality and nutrient input stressors identified as major watershed stressors in the 2009 Cape Fear RBRP. 1.3 Project Success Criteria The Site follows the USACE 2003 Stream Mitigation Guidelines and the "Wilmington District Stream and Wetland Compensatory Mitigation Update" dated October 24, 2016. Cross section and vegetation plot data will be collected in Years 0, 1, 2, 3, 5, and 7. Stream hydrology data and visual monitoring will be reported annually. Stream 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. 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 no less than 1.4 within restored reaches. Channel stability should be demonstrated through a minimum of four bankfull events documented in the seven-year monitoring period. Digital images will be 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. Dairyland 2 Year 3 Monitoring Report Stream Mitigation Site October 2021 Vegetation Success Criteria Specific and measurable success criteria for plant density within the riparian buffers on the Site will follow IRT Guidance. Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover a minimum of two percent of the planted area. Vegetation monitoring will occur between July 1st and leaf drop and includes 11 permanent vegetation plots and four random vegetation plots. The interim measures of vegetative success for the site will be the survival of at least 320 planted three-year old trees per acre at the end of Year 3, 260 five-year old trees at the end of Year 5, and the final vegetative success criteria will be 210 trees per acre with an average height of 10 feet at the end of Year 7. Volunteer trees will be counted, identified to species, and included in the yearly monitoring reports, but will not be counted towards the success criteria of total planted stems. 1.4 Project Components Mitigation credits presented in these tables are based upon site design in the approved final mitigation plan. SMIJ totals were adjusted and calculated using the most recent non-standard buffer width guidance. The stream mitigation components are summarized in Table 1, as well as Figure 2.

A detailed description of the methodology and calculations is described in the Approved Mitigation Plan. 1.5 Design/Approach The design approach for the Site 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 involves the use of a "template" stream adjacent to, nearby, or previously in the same location as the design reach. The template parameters of the analog reach are replicated to create the features Dairyland 3 Year 3 Monitoring Report Stream Mitigation Site October 2021 of the design reach. The analog approach is useful when watershed and boundary conditions are similar between the design and analog reaches (Skidmore, et al., 2001). Hydraulic geometry was developed using analytical methods in an effort to identify the design discharge. Priority Level I Restoration was performed on Reaches HB-2 and UT-2, both of which were farm ponds. Restoration activities included draining and breaching the existing impoundments and constructing channels once the ponds had been breached. A combination of Priority I Restoration and Enhancement Level II was performed along the primary project channel (Reaches HB-1 and HB-2) to address existing impairments, particularly impoundment, floodplain disconnection, and buffer degradation. Enhancement III was performed on Reaches UT-1 and WF-2, as the channel is stable throughout, regularly accesses its floodplain and provides a variety of aquatic habitats. Preservation was performed for Reach WF-I. The channel is stable throughout, regularly accesses its floodplain and provides a variety of aquatic habitats. 1.6 Construction and As Built Conditions Stream construction was completed in August 2018 and planting was completed in November 2018. The Dairyland Mitigation Site was built to design plans and guidelines. Baseline channel length and stationing is based on design centerline. The only notable change that was made during construction was changing the crossing between HB-1 and HB-2 from a culvert to a ford. This modification, which is outside of the conservation easement area, was made based on the large amount of bedrock unearthed after the ponds were dewatered. The design engineer drafted and sealed a bulletin drawing to retain the bedrock features and tie-in with the downstream stream design as shown in the Mitigation Plan. The bulletin is included in Appendix F. Also, a few log structures were removed from the design to utilize the existing bedrock found in the new channel location and retained the designed channel slope. Following Hurricane Florence and Hurricane Michael, the stream construction contractor added rip rap material around the grade control structures from 7+00 to 9+00 on UT-2. During the As -Built Site Visit with the IRT on November 29, 2018, RES agreed that the amount of rip rap material was not appropriate for the design. Shortly after the site visit, RES removed the rip rap from the areas not directly around structures. Two other areas that were identified during this site visit included two small encroachment areas along WF-2 and the general comment to treat invasive species in the )AT-2 easement area. 1.7 Monitoring Performance (MY3) The Monitoring Year 3 (MY3) activities were completed in May and September 2021. All monitoring data is present below and in the appendices. The Site is on track to meet vegetation and stream interim success criteria. Vegetation Monitoring of the 11 fixed vegetation plots and four random vegetation plots was completed during mid - September 2021. Vegetation data are in Appendix C, and associated photos and plot locations are in Appendix B. MY3 monitoring data indicates that all plots but two are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 162 to 1012 planted stems per acre with a mean of 596 planted stems per acre. A total of 12 species were documented within the plots. The average tree height observed in the permanent vegetation plots was 7.8 feet. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. There are two low stem density areas totaling about 0.47 acres in size. The first area is in and around VP2 and the second is in and around RVP1. These areas will be supplemental planted this dormant season. The two small areas of encroachment were addressed in Dairyland 4 Year 3 Monitoring Report Stream Mitigation Site October 2021 October 2020 and are no longer an issue. In January 2021, RES performed supplemental planting of about 600 bareroot trees. The supplemental planting was done in areas where MY2 vegetation plots showed less than 600 stems per acre. Stream Geomorphology Geomorphology data for MY3 was collected during May 2021. Summary tables and cross section plots are in Appendix D. Overall, the cross sections relatively match baseline condition. Minor adjustments are expected in the first few years after 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. One area of bank erosion was observed around a log sill at Cross Section 7. This area is not considered a problem in MY3 due to the thick livestake growth in the area. RES will continue to closely monitor this structure. Stream Hydrology There are two stage recorders on site, one on Reach HB-2 and one on Reach UT-2. Additionally, as requested by the IRT, RES is reporting flow data on Reach UT-2. MY3 hydrology data shows four bankfull events on HB-2 and 10 on UT-2. The highest event on HB-2 was 0.36 feet above bankfull and the highest event on UT-2 was 0.61 feet above bankfull. Reach UT-2 reported 209 consecutive flow days and 240 cumulative flow days. Gauge locations are shown on Figure 2 and full hydrology data is in Appendix E. 2.0 Methods Stream 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 16 cross -sections. Survey data were imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. The stage recorders include a flow gauge and a crest gauge. The flow gauges were installed within the channel and will record flow conditions at an hourly interval. The crest gauges were installed on the bank at the bankfull elevation. During quarterly visits to the Site, the height of the corkline will be recorded. HOBO data from the flow gauges will be corrected using bankfull recordings from the crest gauges. In result of crest gauge failure, the flow gauges will be corrected using the water depth at the gauge and the height of the top of bank at the gauge. Additionally, flow data is corrected using the height of the downstream riffle to detect flow. Vegetation success is being monitored at 11 permanent monitoring plots and four 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 a 100 square meter belt transect. 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.
