Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application:_ The conditions at the site consist of approximately 255 linear feet of impaired, incised stream, exhibiting ailing banks and a lack of riparian vegetation. Land use in the vicinity of the project consists of campgrounds pastures woodland and rural residences. See Appendix A for site photographs. Page 6 of 15 10. Describe the overall project in detail, including the type of equipment to be used: The Macon County Soil and Water Conservation District (MCSWCD) has received a grant from the North Carolina Clean Water Management Trust Fund (CWMTF) to conduct a streambank restoration project. The project area includes a reach of Cartoo echaye Creek within Cartoogechaye Creek Campground. The tributary is classified as "WS-III, Trout" waters throughout the project area. A Level III Assessment and survey of the stream with a total station was performed prior to the design of bank stabilization and riparian enhancement measures. The assessment evaluated the existing conditions of stream morphology and the quality of vegetation within the riparian corridor. Findings of the assessment are included in (Appendix B). A site vicinity map and site plan are included as Figures 1 and 2. Impaired streambanks within the project area of Cartoogechaye Creek exist predominantly on river left and eroding bank heights range from approximately one to five feet above normal water surface elevation. Currently, Cartoo eg chaye Creek cannot access a floodplain within the project area during a bankfull event because of its incised condition, which has caused severe erosion. The proposed stream restoration plan is shown in Figure 3. A stream cross-section is shown in Figure 4 and a longitudinal profile of the creek is shown in Figure 5. The affected property owners have been involved in the decision making process for this project. The agent authorization letter for the project is included as Appendix C. An element of the proposed project design includes providing a secondary bypass channel access for high flows to reach a relic Cartoogechaye Creek channel in order to relieve stress on the river left bank. The thalweg of this secondary channel will be set to approximately six inches below the high water mark elevation. Normal base flow will remain in the primary channel but will be redirected to the center of the channel with log j-hook vanes. These log vanes will divert and dissipate energy away from the vulnerable streambanks. Typical illustrations of stream structures are included as Figures 6, 7, and 8. Eroding streambanks will be stabilized with eolifts (Figure 6) which consist of coir fabric wrapped lifts of rock, soil, and live native plant material. Equipment used to accomplish the above tasks will include a track-mounted excavator equipped with a bucket and hydraulic thumb a loader, and a dump truck to transport materials The project site will be accessed from No Name Road. The equipment will access the creek from a 300-foot gravel road on the Hatch property, which terminates at the picnic area located on river left upstream of the project area. The excavator and machinery will be operated primarily from the riverbank Machinery will not be driven in or operated from the water except when absolutely necessary to complete work The secondary channel will be excavated stabilized and planted in the dry. In order to minimize the release of sediment during bank stabilization of river left large sandbags will be used during low flow conditions to divert the stream way from the work area or to the secondary channel while working in the main channel. The following protocol will be used for the temporary stream diversion: • Weather will be monitored daily and the sandbag stream barriers will be installed only during time periods of dry weather, baseline and low flow conditions • The sandbag stream barrier will be installed from upstream to downstream • The height of the sandbag stream barrier will be one foot higher than normal base flow in the river. • Sandbags will be filled on site using natural channel material deposited as a large bar on river right. Page 7 of 15 • Sandbags will be made of burlap or polypropylene materials which are resistant to UV radiation, tearing and puncture and woven tightly enough to prevent leakage of the fill material. • Seamless polyethylene plastic sheeting with a minimum thickness of 4-mil, resistant to puncture tearing and ultraviolet degradation, or equivalent will be installed on the water side of the sand bags. See Figure 8 for a sandbag diversion detail. • All large debris located at the base of the stream barrier will be removed to ensure proper sealing and to reduce leakage through the barrier. • The sandbag stream barrier will be monitored daily for leakage and repaired as necessary. • Dewatering or pump around techniques are not anticipated. Bank stabilization on river left will include grading banks to stable slopes and installation of eg_olift and benches to bankfull elevation. Excavated materials from the secondary channel and bank stabilization work will be used to build the geolifts. Bank stabilization will address approximately 255 linear feet of the project area. All disturbed areas will be stabilized using native riparian, seed mix, live stakings, bare root and container shrubs, and tree species. A minimum 900 gram per square meter coir fabric will be installed on the graded bank or as components of geolifts from the edge of water to 1.5 times the bankfull elevation. Additionally, the disturbed areas between the coir fabric and the top of bank will be reinforced with coconut jute mesh. Erosion control matting will not contain plastic netting or non- biodegradable materials, will be trenched in on all sides to a depth of six inches, and will be staked down with a combination of wooden and live stakes. Disturbed areas from the edge of water to the top of bank will be seeded with Ernst Conservation Seeds, Riparian Buffer Mix ENRMX-178. Disturbed area below the top of bank will be over-seeded with a nursery crop of grain suitable to the season in which planting will take place. Caution will be used to keep fertilizer and mulch out of the river and above the typical high water elevation. Fescue seed mixes will not be used at the site excep in areas beyond the top of bank. Annual rye or an appropriate seasonal grain will be used for rapid stabilization on soils within the floodplain and will serve as a nursery crop until the riparian planting seed mixes becomes established. More invasive seed, such as lespedeza will not be used on this project. Sedimentation and erosion control practices will be implemented throughout the project and will consist of 1 only working in dry weather during low and baseline flow conditions, 2) only exposing areas of soils that can be stabilized at the end of each work dam) installation of temporary berms at the top of disturbed banks, and 4) installation of soil matting and straw mulch. After stabilization measures are in place, and disturbed areas of the site are seeded, native trees and shrubs in the form of live stakes, bare-root, and container plants will be planted in stabilized areas as well as in other areas of the project reach where riparian vegetation is sparse or narrower than 20 feet from the water's edge. The contractor will be required to install equal numbers of at least six varieties of large trees from the following list: River Birch, Shagbark Hickory White or Green Ash American Beech, Tulip Poplar, Sourwood, Silver Maple, Eastern Cottonwood, Sycamore Black Cherry, White Oak or Southern Red Oak. The contractor will also be required to install equal numbers of at least eight species from the following list of small trees: Downy Serviceberry (Shadebush), American Hornbeam (Ironwood), American Holly Red Mulberry Common Alder Red Chokeberrv, Button Bush, Witch Hazel, Winterberry, Northern Maleberry Catawba Rhododendron Wild Azalea, Blackberry, Dog hobble or Fetter bush. Planting of trees shrubs and live stakes will conform to the specifications outlined in the NCDENR Guidelines for Riparian Buffer Restoration. Page 8of15 Staging areas for equipment and material will be placed in upland areas away from surface water and outside of the floodplain Work will proceed as follows at the work area (as applicable). 1) Flag the work limits. 2) Mark live trees and shrubs to be protected 3) Construct temporary construction entrances/exits where necessary 4) Place erosion control fencing and other protective measures as necessary. 5) Inspect and maintain repairs 11. Explain the purpose of the proposed work: The work is being completed to substantially reduce the amount of sediment entering Cartoogechaye Creek within the project area and provide long-term stabilization of streambanks. The project is designed to return the referenced portion of the creek to a state of stability and to increase its natural potential by providing the creek access to a floodplain and by restoring and enhancing native vegetation within the riparian corridor and shading the stream channel.
