The RCM has been developed to summarize completed work performed according the Adaptive Management Plan(AMP)dated November 16th,2020.The issues and subsequent repair work addressed in this memo include stream channel improvements,additional plantings,cattle encroachment,and invasive plant removal.The AMP was submitted to the Interagency Review Team(IRT)on November 23rd,2020 and a response was provided via email on December 10th,2020 with no formal comments.Permit approvals were received from the U.S.Army Corps of Engineers(USACE)on January 28',2021 for a Nationwide Permit 3—Maintenance,and from NCDEQ Division of Water Resources on February 12',2021 for a Water Quality General Certification No.4123. The work described herein began in February 2021 and was completed by April 2021. UT-2: Issue: An approximately 75-foot segment of the UT-2 channel had an undefined bed and bank as a result of past sediment accumulation. Repair Completed:A 75-foot single thread channel was excavated on February 25th using the originally designed channel dimensions as a guide for the appropriate width and depth(See Appendix B,Plan Sheet 10). The repaired section begins at Station 16+25 and extends downstream to Station 17+00. The location of the channel construction is shown in Appendix A,Plan Sheet 15.All excavation was completed using hand tools to minimize potential damage to trees and shrubs along the banks,and the excavated material was cast upslope into non-wetland riparian areas. On March 14th the channel edges were planted with a 1-2 rows of live stakes, approximately 3 feet apart,within the construction limits(approximately 125 stakes in total).The live stakes consisted of native species of silky willow(Salix sericea),buttonbush(Cephalanthus occidentalis),elderberry (Sambucus canadensis)and silky dogwood(Cornus amomum).The typical planting detail for the live stakes can be found in Appendix A,Plan Sheet 51.The live stakes were observed to be healthy and budding during a follow- up site-visit on April 13th 2021. The pond outfall upstream of UT-2 has remained stable since the removal of the beavers and is no longer a major source of sediment. WSP will continue to periodically observe the outfall. The improved channel section has maintained well-defined bed and banks and should continue to stabilize over time with a consistent geomorphology and vegetated overbanks.Photos of the excavated channel and live stakes are also included in Appendix A. UT-3: Issue: An approximately 400-foot section of the UT-3 channel was poorly defined and damaged by previous cattle encroachment and sediment accumulation from the erosion of an off-site,unused cattle crossing. 1 NN S I ) Repair Completed: Channel: A 400-foot single thread channel was excavated on February 18th and 25`h. The repaired section begins at the upstream end of the conservation easement at Station 10+00 and extends downstream to Station 14+00.The location of the channel construction is shown in Appendix B,Plan Sheet 17. The originally designed channel dimensions were used as a guide for the appropriate width and depth(see Appendix B,Plan Sheet 10). All excavation was performed using hand tools rather than a small,tracked excavator as oringinally decribed in the AMP. The decision to excavate the channel by hand was due to concern that the machinery would have trouble accessing the channel through wet/mucky ground conditions at the upstream end of UT-3,and to mitigate the risk of damaging the trees and shrubs within the riparian buffer. On March 13th,the reconstructed channel edges were planted with a double row of live stakes at approximately 3-foot spacing. The species of live stakes were the same as mentioned for UT-2(above). Live stakes were also installed along the overbanks of the channel near the groundwater seep(10+00 to 12+00). Approximately 800 live stakes were planted along UT-3 in total.The combination of channel excavation and planting of live stakes has restored the channel to its original,functional condition before the bank erosion at the cattle crossing and the cattle encroachment occurred.The area of prior bank erosion at the culvert has since remained stable and is no longer a significant source of sediment. The improved channel section has maintained its well-defined bed and banks thus far and should continue to improve over time with a consistent geomorphology and vegetated overbanks. Riparian Vegetation:WSP completed an initial fall herbicide treatment of the densest areas of tall fescue within the easement and an additional spot treatment was conducted in April 2021. Supplemental planting of native trees and shrubs within the conservation easement was conducted concurrent with the channel work. Approximately 800 live stakes were installed along the channel as noted above. Additional riparian planting included a mixture of native containerized plants as follows:willow oak(Quercus phellos),pin oak(Quercus palustris), sycamore (Platanus occidentalis), persimmon(Diospyros virginiana),elm(Ulmus americana),black gum(Nyssa sylvatica),and river birch(Betula nigra).The plant stock consisted of container-grown plants in No. 1 sized containers(1-gallon),as specified in the AMP.The primary areas covered by these containerized plants in UT-3 measure approximately 1.0 acres in size,as highlighted in Appendix B,Plan Sheet 17. Additional planting areas within the conservation easement along UT-3 were included as plant material allowed. In total,approximately 300 container-grown plants were installed at a spacing of 10-15 feet on-center. Additionally,as a result of successful cattle exclusion, site observations suggest that there have been improvements in the hydrology and soils along this reach since the initial planting effort which should promote vegetative growth. Cattle Encroachment: Issue: Frequent cattle encroachment during the spring and summer months of 2020 had impacted the condition of the stream channel and riparian zone in UT-3 and to a lesser degree along portions of UT-4 and the mainstem of Little Buffalo Creek below(downstream)of Old Mine Road. Repair Completed: Total exclusion of cattle from the easement has been achieved over the past 6 months and has significantly improved the condition of the site.The last instance of cattle encroachment was limited to a single calf in October of 2020. That calf was promptly removed and caused minimal damage within the easement.Evidence of cattle damage from previous encroachments during the first half of 2020,such as cattle trails,damage to the stream channel,and browsing of vegetation is naturally recovering and much less notable. Frequent communication has been ongoing with Mr.Marcus Harward(cattle owner and lessee of pasture),Mr. Phillip Cline(pasture owner),as well as Mr. Allen Hammill(the primary landowner of the western crop and hay fields). Mr.Harward agreed to have his ranchers ride the perimeter of the easement fence weekly to ensure there are no damaged sections of fence through which cattle may enter the easement.Mr.Harward also agreed to perform maintenance on the fencing and crossing,and to keep the gate closed at the eastern side of the cattle crossing until such time as the cattle were moved to the lower western pasture.We are still engaged with Mr. Harward and Mr. Cline to develop a permanent water source for cattle in the lower western pasture owned by Mr. Cline. Mr. Cline has been clearly informed that as the landowner he will be responsible for any cattle incursions within the easement.To date,limiting cattle access to the crossing and regular fence inspection and maintenance 2 NN I ) has alleviated the risk that cattle may attempt to enter the easement. Additionally,monthly site visits by WSP and NC DMS as well as routine inspection by Mr.Harward will ensure that any fence damage is promptly addressed. The joint effort between WSP,Mr.Harward,and Mr.Hammill to prevent cattle encroachment has proven successful thus far and will continue throughout 2021 to meet the IRT requirement of no encroachment for a full year of monitoring. The additional wire fence previously installed by WSP at the Old Mine Road bridge has remained in place. Several sections of the main easement fence were damaged during a recent flood but have since been repaired and are fully functional.All of the fence damaged during the flood was located on the western side of the easement, where no cattle are kept in the adjacent fields. WSP has been conducting monthly inspections of the conservation easement,checking fence condition,and looking for signs of cattle encroachment.WSP will continue the monthly inspections throughout the summer/fall and has discussed coordinating the site visits with DMS,who has also been inspecting the site monthly. Moving forward the site will be inspected by either party on a bi-weekly basis. Invasive Plants: Issue: Some recurrence of treated invasive species including Chinese privet and tree-of-heaven has been observed within the easement.Multiflora rose and Japanese honeysuckle have also been noted by WSP and DMS staff. Repair Completed/Ongoing: The presence of invasive plants has been greatly reduced within the easement,as noted by the IRT during the initial site review on July 2nd,2020. Invasive plant removal has since been performed regularly throughout the winter of 2020 and spring of 2021. The stream restoration and enhancements corridors are walked regularly and invasive plants have been cut down or removed by hand-pulling as encountered. Additionally,patches of fescue along UT-3 were sprayed with an herbicide treatment in October 2020 and again in April 2021.Treatment and removal of invasive species will continue throughout the year,with an emphasis on treating and removing remaining patches of Japanese honeysuckle,Chinese privet,and multiflora rose along the main stem near the confluences with UT-2 and UT-3,as well as near the confluence of UT-7 and UT-8. Future treatment will consist of herbicide application,in addtion to mechanical removal. Monitoring: Since the completion of the stream channel corrections and additional plantings on March 14th,WSP has begun periodic visual monitoring of site conditions along the entire channel and riparian zones of UT-2 and UT-3. Photographs of UT-2 and UT-3 from a recent site visit on April 5th are included at the end of both Appendix A and B. No significant degredation or channel issues have been noticed wihtin the repair reaches nor along the mainstem and other tributaries. Visual inspection and associated documentation will continue throughout 2021. The beaver dam at the pond outfall above UT-2 has been removed and according to Mr. Hammill,the beavers have been removed as well.The pond outfall has been stable since the removal of the beaver dam and there have been no signs of excessive sediment loads from the pond outfall. Five additional l Om by l Om plots have been assessed for tree and shrub density within the UT-3 riparian zones following the supplemental planting. The location of the plots,data collected,and photos from monitoring on April 5th can be found in Appendix C. The plots were set as close as possible to the locations of the random vegetation plots previously conducted(April 2020).The monitoring will be repeated again in the fall toward the end of the growing season and will also include the original monitoring plot and at least one additonal monitoring plot for a total of seven plots. Permitting: WSP received the following permits prior to performing in-stream channel corrections: • Section 404 Nationwide Permit 03 authorized by USACE on January 28th,2021 (See Appendix D) • Section 401 Water Quality Certificate General Certification 4132 approved by NCDEQ on February 12th, 2021 (See Appendix D) 3 NN S I ) The work outlined above was completed in accordance with permit conditions. Project Closeout: WSP is proposing a project closeout visit to be scheduled for November or early December of 2021.Based on the completion of the repair work described above,and continued exclusion of cattle from the easement,WSP anticipates requesting a full credit release for UT-2 and UT-3 for a combined total of 1,259 SMUs. Please let me know if you have any quesitons regarding the Repair Complete Memo. Sincerely, WSP USA Solutions,Inc.
