The RHBRS is a riparian system in the French Broad River Basin (06010105 8-digit cataloging unit) in Buncombe County, North Carolina. The site’s natural hydrologic regime had been substantially modified through the relocation and straightening of the existing stream channels, livestock impacts, and clearing of the riparian buffers. This site offers the chance to restore streams impacted by agriculture to a stable stream ecosystem with a functional riparian buffer and floodplain access. Site grading was initially completed in June 2021 with no major changes from the construction plans. From August 15 – 18, 2021, the site received 7.6” of rain. This large scale rain event caused a significant amount of deposition to the upper portion of RHB-1, mainly upstream of the first crossing. This deposition, along with a few areas of bank scour along RHB-2, was repaired in September 2021. These repairs involved removing the sediment that had been deposited in the stream and sloping back and reinstalling coir matting on the scoured banks. One small area of floodplain scour located on the left bank, just downstream of the confluence of RHB and T2, was left as a floodplain depression. This area has been stabilized with floodplain vegetation and is not anticipated to expand. It also acts as an ephemeral pool and provides beneficial habitat diversity to the site. Project planting was completed on December 20, 2021 and the monitoring components were installed on January 19, 2022. Table 1.

Five of the six vegetation monitoring plots achieved all of the success criteria. Plot 3 had only 2 native hardwood species and 208 stems/acre. This area of the site, which includes the very bottom of the main stem and the area around T2, did not see as robust growth of the planted woody stems as the rest of the site during the first two years. KCI is planning a supplemental planting in this area of the site, which will take place in the winter before the 2024 growing season. Despite this small area of poor vigor, the site as a whole is well vegetated with many healthy woody stems and a thick and diverse herbaceous layer. The MY02 cross-section survey found that the stream was functioning as designed with some small variation as is typical for stream restoration projects. Several of the cross-sections showed signs of aggradation, particularly along the tributaries. This is a result of the large sediment source from the unbuffered reaches just upstream of the project. KCI does not believe that these small amounts of aggradation are signs of instability in the streams, but rather just the natural movement of sediment through the system. During 2023, the gauge on RHB recorded 2 bankfull events. The stream gauge on T1 recorded a maximum of 36 consecutive days of flow, while the flow camera on T1 recorded a maximum of 102 consecutive days of flow. The gauge on T2 recorded a maximum of 136 consecutive days of flow, while the camera on this reach recorded 115 consecutive days of flow. Differences in the number of days recorded by the cameras from those recorded by the gauges are generally due to the cameras becoming obscured by vegetation during the growing season or the stream flowing at levels too low for the gauges to accurately record. There are two issue areas in terms of fencing with adjoining landowners. One area is at the top of Round Hill Branch where there is existing fence located approximately 5 feet inside of the conservation easement. The second area is at the bottom of Round Hill Branch where an existing fence pole is within the conservation easement. KCI has addressed these issues with the adjacent landowners and is planning to move the fence to the appropriate location in early 2024. The site boundaries were inspected on December 11, 2023. Besides the ongoing issue described above, no other areas of encroachment were noted. REFERENCES NCDENR, Ecosystem Enhancement Program. 2009.
