Project Timeline and Contact Information Six Runs Mitigation Project 1 Year 1 Monitoring Report Project #100170 February 2024 1 Project Summary 1.1 Project Location and Description The Six Runs Stream and Wetland Mitigation Project (Project) is located within Sampson County, approximately six and a half miles west of Faison, NC. The Project lies within the Cape Fear River Basin, North Carolina Department of Water Resources (NCDWR) sub-basin 03-06-19 and United States Geological Survey (USGS) 14-digit hydrologic unit code (HUC) 03030006110010 (Six Runs Creek Watershed; Figure 1). The Project was designed to help meet compensatory mitigation requirements for stream and wetland impacts in the HUC 03030006. The Project restores 5,788 linear feet (LF) and enhances 1,656 LF of stream as well as re-establishes 6.221 acres (ac), rehabilitates 4.913 ac, enhances 1.008 ac, and preserves 1.656 ac of wetlands that will ultimately provide water quality benefits and ecosystem uplift for the Project’s 0.89 mi2 (570 ac) drainage area. The Project is comprised of a 30.94-acre easement located along Six Runs Creek, encompassing a portion of the Six Runs Creek floodplain and several tributaries. The Project involves Brad’s Branch (a colloquial name for the primary tributary feature draining to Six Runs Creek), five of its unnamed tributaries, and riparian wetlands that all drain into Six Runs Creek which eventually drains south to the Black River. The stream and wetland mitigation components are summarized in Table 1. The upstream extent of the Project begins at a property boundary upstream of E Darden Road and the downstream extent ends within the Six Runs Creek swamp. The site is easily accessible from E Darden Road. Coordinates for the Project are as follows: 35.0962°, -78.2304°. 1.2 Project Components Prior to restoration, the riparian corridors within the Project had been manipulated by agricultural practices over time, thereby adversely impacting both streams and wetlands. Most streams were degraded in varying degrees and were restored or enhanced to attain higher function. Non-jurisdictional areas of hydric soil within riparian areas were restored via re-establishment to improve both hydrologic and vegetative functions. Jurisdictional riparian wetland areas that were severely degraded in terms of vegetation and riparian function were rehabilitated to improve vegetative function and stream interaction. Other jurisdictional wetland areas that were partially forested but degraded from constant cattle pressure were enhanced to improve vegetative function. A small area of mixed, jurisdictional wetland types, including frequently inundated marsh and forested swamp, within the Six Runs floodplain, were preserved. Importantly, cattle no longer have access to the aquatic resources within the Project. These improvements to the Project will help meet the river basin needs expressed in the Division of Mitigation Services’ (DMS) 2009 Cape Fear River Basin Restoration Priorities (RBRP). Through stream restoration and enhancement, the Project presented 7,444 LF of stream mitigation, generating 6,660.599 Warm Stream Mitigation Units (SMUs). By incorporating wider buffers, the total adjusted SMUs for the Project amounted to 6,724.599 SMU (Table 1). Additionally, the Project presented 13.798 acres of wetland re-establishment, rehabilitation, enhancement, and preservation, generating 10.044 Riparian Wetland Mitigation Units (WMU; Table 1). Additional wetland areas amounting to 1.379 acres were presented that will not generate mitigation credit but are protected within the conservation easement. These asset numbers reflect those in the approved mitigation plan. Six Runs Mitigation Project 2 Year 1 Monitoring Report Project #100170 February 2024 Table 1.

The past land use disturbances, absence of buffer vegetation, and current agricultural practices presented a significant opportunity for water quality and ecosystem improvements through the implementation of this Project. Through the comprehensive analysis of the Project’s maximum functional uplift using the Stream Functions Pyramid Framework, specific, attainable goals and objectives are being realized by the Project. These goals clearly help to address the degraded hydrology, water quality, and habitat from agricultural practices that were identified as major watershed stressors in the DMS 2009 Cape Fear River Basin Restoration Priorities (RBRP) and within DMS’ Targeted Resource Areas (TRA). Ultimately, the Project supports DMS’ watershed goals listed in the Approved Mitigation Plan. The Project Summary Goals, Performance, and Results are provided below in Table 2.

The Six Runs Project was built to design plans and guidelines with some minor modifications. Such modifications are summarized below:  Added several Post-Assisted Log Structures (PALS) to reaches BB-A/B;  Swapped several brush toes for stone toes;  Swapped two brush toes for sod mats in lower portion of reach BB-C;  Added floodplain sills in very wet areas susceptible to erosion;  Minor alignment change at upper segment of BB-C – This was a design revision in the Final Construction Plans. This did not result in change in LF.  Minor alignment change at lower segment of DE7 – This was a field-adjustment to avoid an existing mature tree. This resulted in minor loss of LF. Also, note that fencing was not surveyed in the areas surrounding reaches BB-A/B (above E Darden Rd.); however, fencing was installed and verified in the field. The missing areas will be surveyed as soon as possible and will be provided in the Final As-built Survey and Baseline Monitoring Report. The as-built survey and record drawings are included in Appendix F. There were no changes to the planting plan (Table 7 in Appendix B). Minor monitoring device location changes were made during as-built installation, however, the quantities remained as proposed in the Mitigation Plan. 1.5 Year 1 Monitoring Performance (MY1) The Six Runs Year 1 Monitoring activities were performed in November 2023. All Baseline Monitoring data is presented below and in the appendices. The Project is on track to meeting stream, wetland, and vegetation interim success criteria. 1.5.1 Vegetation Monitoring of the 13 permanent vegetation plots and six random vegetation plots was completed on November 8th, 2023. Vegetation data is in Appendix B, and associated photos and plot locations are in Appendix A. MY1 monitoring data indicates that 18 of 19 plots exceed the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 283 to 972 planted stems per acre with a mean of 586 planted stems per acre across all plots. A total of 21 planted species were documented within the plots. The average stem height in the vegetation plots was 2.0 feet. Data at one random vegetation plot, (RVP-6) located in the riparian area of reach DE4-B, represented only 283 stems per acre. This back- calculates to being one tree short of the success criterion within the plot. However, a portion of this plot was located in an existing forested area that was only supplementally planted at a much lower density. In fact, if existing, mature trees within the plot had been counted, the stem density would have exceeded the 320 stems per acre success criterion. With that said, RES will continue performing random plots in the same general area in future years. Visual assessment of vegetation outside of the monitoring plots indicates that herbaceous vegetation is established throughout the project area (Appendix A). Small clusters of cattails were observed sporadically Six Runs Mitigation Project 7 Year 1 Monitoring Report Project #100170 February 2024 throughout floodplain areas but are currently too small to map. However, RES is aware that they could become more widespread in the future and will assess again in 2024 and remediate, if necessary. 1.5.2 Stream Hydrology Three stage recorders and five flow gauges were installed on March 28th, 2023, and continue to record stream hydrology events. The stage recorders are in place to document bankfull events. Two stage recorders were installed on BB-C and one was installed on DE-4. - The stage recorder on BB-C DS (the downstream of BB-C) recorded three bankfull events in MY1 with the highest reading being 0.67 feet above the top of bank. - The stage recorder on BB-C US (upstream of BB-C) recorded four bankfull events in MY1 with the highest reading being 0.49 feet above the top of bank. - The stage recorder on DE4-B recorded five bankfull events in MY1 with the highest reading being 0.91 feet above the top of bank. The flow gauges are in place to document the presence and persistence of stream flow in intermittent channels. One flow gauge was installed on each of the reaches: BB-A, MT2, DE7, DE2-B, and DE8. - The flow gauge on BB-A documented 71 consecutive days of flow. - The flow gauge on MT2 documented 18 consecutive days of flow. o MT2 is an Enhancement II reach where cattle exclusion was the primary activity to provide functional uplift. With two consecutive dry years and data only being collected since March 30th, 2023, RES is confident that flow success criterion will be met during a normal wet season. - The flow gauge on DE7 documented 222 consecutive days of flow. - The flow gauge on DE2-B documented 142 consecutive days of flow. - The flow gauge on DE8 documented 148 consecutive days of flow. Stream hydrology data is presented in Appendix D, gauge locations can be found on Figures 2a-c, and photos are in Appendix A. 1.5.3 Stream Geomorphology Geomorphology data collection for MY1 was collected on November 8th, 2023. Summary tables and cross section plots are in Appendix C. Overall, the MY1 cross sections relatively match the proposed design and as-built condition. MY1 conditions show that shear stress and velocities have been reduced for all restoration reaches. All reaches were designed as gravel bed channels and remain classified as gravel bed channels 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 (Appendix C). RES noted significant aquatic and/or wetland vegetation throughout much of the stream channels. Since construction of the stream, abnormally dry conditions have persisted while floodplain herbaceous vegetation has thrived. This combination has led to favorable conditions for in-channel vegetation to also thrive. RES feels that with adequate precipitation and future, flushing flows will alleviate some of the issue. However, RES will continue to monitor the situation and report the condition and propose remedial action, if necessary, in MY2. Six Runs Mitigation Project 8 Year 1 Monitoring Report Project #100170 February 2024 1.5.4 Wetland Hydrology Six wetland gauges were installed in wetland re-establishment areas; two were installed in wetland enhancement areas; two were installed in wetland rehabilitation areas; and one was installed in a wetland preservation area to serve as references. These gauges were installed on March 28th, 2023. Data recorded in MY1 demonstrates consecutive hydroperiods ranging from two to 58 percent across all wetland gauges onsite. Only three of 11 wetland gauges met the 12 percent hydroperiod. GW3, GW4, GW5, GW7, and GW9 fell short of the 12 percent success criteria with hydroperiods ranging from two to seven percent. None of the wetland gauges in re-establishment areas passed while one in a rehabilitation area also did not pass. Unfortunately, there is no data to be reported for GW1, GW2, or GW11 for various reasons. GW1 appeared to be in working condition, but the data files retrieved are corrupt or there was some other malfunction with the pressure transducer data logger. RES is attempting to see if any lost data can be retrieved but will replace the transducer regardless. The transducer in GW2 had died prior to downloading. This wetland gauge has been in place for several years as it was in place to document pre- existing conditions. However, the transducer was replaced on November 8th, 2023. RES discovered the transducer in GW11 to be missing, likely from an animal or trespasser. It was also replaced on November 8th, 2023. Though MY1 data presents generally underwhelming hydroperiods, RES does not believe this will be a trend in future years under normal rainfall conditions. The combination of two consecutive years of abnormally dry climate resulting in depressed water tables across the landscape as well as post-construction ground disturbance, has surely affected wetland hydrology. Further, according to the licensed soil scientists’ hydric soil report for the Project, it is reasonable to expect lower hydroperiods in the first year: For the first year after construction, it may be practical to expect a hydroperiod of less than 12 percent if rainfall patterns are below normal as deep soil becomes saturated and a higher groundwater table becomes established. RES will continue to monitor wetland hydrology and will also take note of establishing hydrophytic vegetation to supplement wetland data in future monitoring reports. Wetland gauge locations can be found in Figures 2a-c. Soil characterization forms, recorded for each groundwater well, can be found in the MY0 Baseline Monitoring Report, Appendix D. It also appears that extensively more wetland area is being restored and/or created in the riparian areas along Brad’s Branch above where mitigation credit is currently being generated. RES plans to investigate these areas further in 2024 and may opt to install additional wetland gauges to document hydrology to determine potential viability for wetland mitigation.
