In these cases, proof of payment shall be provided to. the Division before any impacts occur on site. Water quality Certification No. 3886 Water Quality Certification No. 3886 11.. Relocated stream designs should include the same dimensions, patterns, and profiles as the existing channel (or a stable reference reach If the existing channel Is unstable), to the maximumextent practical. The new channel should be constructed in the dry and water shall not be turned intothe new channel until the banks are stabilized. Vegetation used for bank stabilization shall be limited to native woody species and should Includeestablishment of a 30 -foot wide wooded and an adjacent 20 -foot wide vegetated buffer on both sides of the relocated channel to the maximum extent practical. A transitional phase incorporating appropriate erosion control matting materials and seedling establishment is allowable, however matting that incorporates plastid mesh and/or plastic twine shall not be used In wetlands, riparian buffers or floodplains as recommended by the North Carolina Sediment and Erosion Control Manual. Rip -rap, AJacks, concrete, gabions or other hard structures may be allowed if it is necessary to maintain the physical integrity of the stream; however, the applicant must provide written Justification and any calculations used to determine the extent of dip -rap coverage. Please note that If the stream relocation Is conducted as astream restoration as defined in the US Army Corps of Engineers Wilmington District, April 2003. Stream Mitigation Guidelines (or its subsequent updates), the restored length may be used as compensatory mitigation for theimpacts resulting from the relocation. 12.

Notification to the Division including supporting documentation such as, but not limited to, a location map of the culvert, geotechnical reports, photographs, etc shall be provided to the Division a minimum of 60 days prior to the installation of the culvert. If bedrock is discovered during construction,. then the Division shall be notified by phone or email within 24 hours of discovery. If other site-specific topographic constraints preclude the ability to bury the culverts as described above and/or it can be demonstrated that burying the culvert would result in destabilization of the channel, then exceptions to this conditionrequire application, submittal to, and written approval by, the Division of Water Quality, regardless of the total impacts to streams or wetlands from the project. Water Quality Certification No, 3886 Water Quality Certification No. 3886 Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately accommodate high water of flood conditions. Additionally, when roadways, causeways, or other fill projects are constructed. FEMA -designated floodways or wetlands, openings such as. culverts or bridges: must be provided to maintain the natural hydrology of the system as well as prevent constriction of the floodway that may result in. destabilization of streams or wetlands. The establishment of native, woody vegetation and other soft stream bank stabilization. techniques must be used where. practicable Instead of riprap or other bank hardening methods, 14. All temporary fill and culverts shall be removed and the impacted area returned to natural conditions within 60 days of the determination that the temporary impact is no longer necessary.. The impacted areas shall be restored to original grade, including each. stream's original cross sectional dimensions, plan form pattern and longitudinal bed and bed profile, and the various sites shall be stabilized with natural woody vegetation (except for the approved maintenance areas) and restored to prevent erosion. 15. All: temporary pipes/ culverts/ riprap pads etc, shall be Installed in all streams as outlined In the most recent edition of the North Carolina Sediment and Erosion Control Planning and Design Manual or the North Carolina Surface Mining Manual sous. not to restrict stream flow or cause cis -equilibrium during use of this General Certification. 16. Any riprap required for proper culvert placement, stream stabilization,or restorationof temporarily disturbed areasshall be restricted to the area directly impacted by the approved construction activity. All rip -rap shall buried and/or "keyed in" such that the original stream elevation and streambank contours are restored and. maintained. Placement of rip -rap or other approved materials shall not result in de -stabilization of the stream bed or banks upstream or downstream of the area. 17. Any rip -rap used for streamstabilization shall be of a size and density so as not to be able to be carried off by wave current: action, or stream flows and Consist of clean rock or masonry material free of debris or toxic pollutants. Rip -rap shall not be installed in the streambed except m specific areas required for velocity control and to ensure structural. integrity of bank_ stabilization measures. 16. A one-time application of fertilizer to re-establish vegetation is allowed in disturbed areas including riparian buffers, but is restricted to no closer than 10: feet from top of bank of - streams. Any fertilizer application must: comply with all other Federal, State and Local regulations. 19.

Our comments on this application are offered for your consideration under provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). This project should not affect trout and the activities do not need to be avoided during the trout spawning moratorium. However, the Southern Blotched Chub (Erimystax insignis eristigma,) and French Broad River Crayfish (Cambarus reburrus), both US Federal Species of Concern and NC Significantly Rare, are found in Mud Creek in the vicinity of the Johnson Drainage Ditch confluence. Mud Creek is on the 2014 303(d) list of impaired waters and suffers from urban impacts such as stormwater flows and pollutants. The application proposes to redevelop a currently impervious area along Mud Creek. The project will involve additional fill to raise the elevation of the land. The site is situated in the floodway of the Mud Creek floodplain, which stores and treats floodwater. The NCWRC does not support commercial or residential development within the 100 -year floodplain. The filling of floodplain increases the potential for flooding and degrades in -stream habitats for fish and other aquatic organisms. However, we support the applicant's intention to compensate for this loss of floodplain storage capacity by enhancing the flood treatment capacity of an adjacent 13 -acre parcel to the south of the site along Mud Creek, as described by Mr. Tinklenberg on the phone on June 17, 2016. Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919)707-0220 • Fax: (919)707-0028 Hendersonville Publix Page 2 July 7, 2016 Johnson Drainage Ditch, Henderson County Stormwater from the site will be treated with underground detention/water quality systems, which are designed to treat the 1-year I-hour storm, drawing down over 2-5 days. We offer the following recommendations for the project to minimize impacts to fish and wildlife resources: 1. Sediment and erosion control measures should be installed prior to any land clearing or construction. These measures should be routinely inspected and properly maintained. Disturbed areas should be seeded, mulched and/or matted as soon as possible. 2. Any erosion control matting used be free of plastic or nylon mesh, as this type of mesh netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last for years. 3. We appreciate the measures the applicant has proposed in order to treat and detain stormwater on-site. We recommend bolstering stormwater management in order to mimic a hydrograph consistent with an impervious coverage of less than 10%. 4. NCWRC recommends a minimum 100-foot undisturbed, native, forested buffer along Mud Creek and any other perennial streams, and a minimum 50-foot buffer along intermittent streams and wetlands. We understand that the site is already impacted and that a narrow buffer exists along Mud Creek; however, we recommend that the applicant widen this forested buffer as much as feasible. Maintaining undisturbed, forested buffers will minimize impacts to aquatic and terrestrial wildlife resources, water quality, and aquatic habitat both within and downstream of the project area. Wide riparian buffers are helpful in maintaining stability of stream banks and for treatment of pollutants associated with urban stormwater. In addition, these buffers will provide an adequate travel corridor for wildlife species. 5. Use non-invasive native species and Low Impact Development (LID) technology in landscaping. Using native species instead of ornamentals should reduce the need for water, fertilizers and pesticides. Using LID technology in landscaping will not only help maintain the predevelopment hydrologic regime, but also enhance the aesthetic and habitat value of the site. 6. We recommend planting undeveloped parts of the parcel with native vegetation and maintaining these areas as green space. Thank you for the opportunity to review and comment on this project.
