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.

Four of the six vegetation monitoring plots achieved all of the success criteria. Plots 3 and 1R both had only 3 native hardwood species. KCI believes that over time, native volunteers will supplement the lower level of species diversity that was seen in these areas. Overall the site is well vegetated with a thick and diverse herbaceous layer. The MY01 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 pool cross-sections showed signs of aggradation. This is a result of the large sediment source from the unbuffered reach just upstream of the project. The system is also continuing to process the sediment that was deposited during the August 2021 storm. 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, especially after such a large scale event as the project streams experienced just after construction. During 2022, the gauge on RHB recorded 10 bankfull events. The stream gauge on T1 malfunctioned and did not start recording properly until October 31, missing the majority of the time that the stream flowed in 2022. Because of this malfunction, the gauge on T1 recorded a maximum of 21 consecutive days of flow, while the flow camera on T1 recorded a maximum of 181 consecutive days of flow. The gauge on T2 recorded a maximum of 209 consecutive days of flow, while the camera on this reach recorded 83 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. 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 is continuing to address these issues with the landowners and is actively working towards getting the fence moved to the appropriate location.

Subject: Round Hill Branch Restoration Site Baseline Site Review – Response to IRT Comments French Broad River Basin - 06010105 Buncombe County, North Carolina DEQ Contract No. #7534 DMS Project #100066 USACE AID #: SAW-2018-01168 Below are our responses to comments received on July 7, 2022 after the baseline report review for the Round Hill Branch Restoration Site. Please contact me if you have any questions or would like clarification concerning these responses. Kim Browning, USACE: 1. What is the total area of floodplain scour that you refer to as vernal pools that enhance ecological function to the site? Will these areas be planted with herbaceous cover to prevent further scouring, and will these areas be re-planted with woody species as described in the final mitigation plan? KCI Response: The scour area is less than 0.01 acres in size. The site had not been planted at the time of the scour event and so no woody stems were damaged during the event and no re-plant is currently planned. During the first growing season, the area was well colonized by herbaceous species and further scour is not anticipated. 2. Please inform the IRT once the fencing encroachments have been resolved. KCI Response: KCI is actively working to resolve the fencing encroachments and will notify the IRT once this issue is resolved. 3. Although the snow-covered photos are aesthetically pleasing, please provide photos that show the condition of the buffer and stream banks in future reports. KCI Response: While we typically try to avoid doing fieldwork in the snow, it was unavoidable in this case. We will make an effort to avoid this for future projects. A video of a drone flight of the site, taken in November 2021 can be found here: https://youtu.be/4AINxWWJGXo and another video of a drone flight of the site, taken in June 2022 can be found here: https://youtu.be/P138sm21ea0 4. Please provide an additional photo for the crossing where photo point 1 is located, from the perspective of looking upstream at the crossing (position yourself near STA 14+00). Both photos of this crossing show the gates open, so livestock access to the ford crossing is a concern. KCI Response: This photo has been provided in the MY01 report. During the first monitoring year there have been no signs of damage or instability in and around this crossing. Erin Davis, DWR: 1. DWR was glad that the two easement dispute areas were identified early. We encourage making every effort to resolve these issues prior to the 2023 credit release meeting. KCI Response: See response to USACE comment 2. 2. DWR requests photos of the floodplain scour area and the drainage swale feature be included in the MY1 report. KCI Response: These photos have been added to the MY01 report. 3. Please show all existing wetland areas within the project easement on future CCPV figures. KCI Response: Existing wetland areas have been added to the CCPV. 4. Given that the as-built survey was performed in May 2021 and long. profile surveyed in August 2021, it would’ve been helpful to include supplemental non-snow covered project photos in the MY0 report. Please make a note for future projects. KCI Response: See response to USACE comment 3. 5. DWR appreciated that DMS’ site visit comments (and KCI’s responses) were included for this review. Todd Bower, USEPA: 1. There were a few, relatively minor deviations from the original design plans; primarily these were due to adjustments due to bedrock encountered during construction. 2. Many planted species were not identified during vegetation monitoring due to monitoring during dormancy. This resulted in fewer species than planted noted on some of the veg plots. No comment as this will be corrected in the coming MY survey. Counts/percentages; all appear suitable and maintains a diverse mix of species. KCI Response: All woody stems were identified to species during the MY01 survey. 3. No adaptive management plan needed at this time. 4. No issues of conservation easement encroachment however there are two areas where fencing and conservation easement boundaries are being actively addressed with the adjoining landowners. 5. I recommend adding the pool adjustments made (due to bedrock) to the longitudinal profile for comparison of design and actual. Noted locations at T1 (sta.10375), and missing pools on RHB (stas. 1080, 1290 and 1340). KCI Response: All adjustments that were made were added by as red-lines to the as-built plans. 6. I noted a slight discrepancy in the stream credits calculated in Table 1. The As-Built length of streams is 2,242 feet and the length of streams removed for credit due to crossings is 114 feet. This results in a final credit amount of 2,128 cool SMUs. It appears that the stream segments removed from credit are tallied from the Original Mitigation Plan lengths (2,256 – 114 = 2,142). Recommend KCI take another look at these totals and correct if necessary. KCI Response: Credit lengths are generally calculated using the approved mitigation plan lengths unless there is significant deviation found during the as-built survey.
