REGAN LINDA CULPEPPER In w/ Dir'eclor Water Resources Lncironmcnml Quality June 6, 2018 DWR # 20180582 Jackson County Cashiers Canoe Club Development, LLC Attn: Roseanne Giordani PO Box 300849 Austin, TX 78703 Subject: REQUEST FOR ADDITIONAL INFORMATION Cashiers Canoe Club Development and Lake Dredging Dear Ms. Giordani: On April 26, 2018, the Division of Water Resources — Water Quality Programs (Division) received your application dated April 24, 2018, requesting an Individual Water Quality Certification from the Division for your project. The Division has determined that your application is incomplete and cannot be processed. The application is on -hold until all of the following information is received: 1. Provide a detailed purpose and need for lake dredging. This should include an analysis of what activities are unable to occur if the wetlands are not impacted, and whether the activities could be practically accomplished if the wetland impacts are reduced. [15A NCAC 02H .0506(b)] 2. Provide a schedule for the construction of the proposed development (subdivision, hotel, parking area, and associated amenities). [15A NCAC 02H .0506(b)] 3. Provide a purpose and need for the bulkheads, including impacts #2, #3, #5, #9, and #11. Also provide a detailed avoidance and minimization analysis for the bulkheads. [15A NCAC 02H .0506(b)] 4. The jurisdictional determination submitted with the application indicates that there are/were out parcels that were not delineated, specifically an out parcel between wetland 3 and wetland 5 that may have additional jurisdictional features. Please locate all wetlands, streams, and other waters of the state as overlays on a detailed site plan. This should include all areas identified as jurisdictional by the USACE within the project boundary. Also clearly locate the Chattooga River where it is immediately adjacent to the project boundary. [15A NCAC 02H .0502] State of North Carolina I Environmental Quality I Water Resources 1617 Mail Service Center I Raleigh, North Carolina 27699-1617 919 807 6300 Cashiers Canoe Club Development, LLC DWR#f 20180582 Request for Additional Information Page 2 of 4 5. Please note that in accordance with 15A NCAC 02H .0500, the Division requires mitigation for all impacts greater than 1 acre of wetlands. Your proposed total wetland impacts for this project are 6.96 acres. You propose in your application to mitigate for impacts by payment to the Division of Mitigation Services (DMS). Provide an acceptance letter from DMS indicating acceptance of 6.96 acres of wetland mitigation. 6. Provide more details regarding avoidance and minimization for impact #13. The application does not discuss what the purpose of the parking area and building is for. Revise the plans to minimize the impacts or provide a detailed explanation of why this plan for the activity cannot be practically accomplished, reduced or reconfigured to better minimize disturbance to the wetland. [15A NCAC 02H .0506(f) and (g)] 7. Provide more details regarding avoidance and minimization at impact #6, #7, and #8. Show all existing access roads/driveways/culverts for the existing development and homes within this area on the plans. Provide a detailed explanation of why the development layout/design cannot be practically accomplished, reduced or reconfigured to better minimize disturbance to the streams and/or wetlands. [15A NCAC 02H .0506(f) and (g)] 8. Provide a site plan with the proposed development and lot layout as an overlay including jurisdictional features. Provide building envelopes for all lots with wetlands, streams or trout buffers and stormwater setbacks on the site plans to demonstrate these lots are able to be developed without additional jurisdictional impacts. Please be advised that deed notifications or other legal language that clearly indicates to future owners that there are jurisdictional features and that some lots may not be buildable as planned without impacts that may not be approved by the regulatory agencies will be a condition of the 401 Water Quality Certification. [15A NCAC 02H .0502(g)] 9. Clarify whether the Division of Energy, Mineral and Land Resources will require riprap within any stream channels or wetlands as part of the Erosion & Sedimentation Control Plan approval (including temporary impacts from lake dewatering discharge). If riprap is required, enumerate and clearly label the temporary and permanent impacts on the site plan and submit a channel restoration detail. Riprap must be located below the stream bed elevation. [15A NCAC 02H .0506(f) and (g)] 10. Enumerate all wetland and stream impacts including but not limited to fill slopes/ dissipater pads/temporary dewatering impacts on the site plan and clearly label impacts. The Division recommends highlighting by hatching or shading all permanent and temporary impacts. [15A NCAC 02H .0502(g)] 11. Provide a detailed engineering plan, profile view, and cross-section of all proposed culverts. These drawings must include details regarding stream alignment in relation to Cashiers Canoe Club Development, LLC DWR# 20180582 Request for Additional Information Page 3 of 4 pipe alignment, pipe slope, pipe burial, and dissipater pad. Provide cross section details that clearly show the provisions for aquatic life passage. [15A NCAC 02H .0502(b)] 12. Provide details on how you are going to maintain the physical integrity of the stream above and below the culvert where multiple culverts are proposed. Where multiple pipes or barrels are required, they shall be designed to mimic natural stream cross section as closely as possible including pipes or barrels at flood plain elevation and/or sills where appropriate. Widening the stream channel should be avoided. Stream channel widening at the inlet or outlet end of structures typically decreases water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage. A construction sequence and detail should be provided to ensure the contractor is clear on construction of these benches. [15A NCAC 02H .0506(b)(2)] 13. The stream impact length should be measured along the centerline of the stream. When proposing a culvert, the impact length is generally greater than the length of the culvert and associated dissipater since the existing stream usually has some sinuosity (curvature). Verify that stream lengths have been surveyed or are otherwise accurate or provide updated impact lengths. [15A NCAC 02H .0502(b)] 14. All development within this project is subject to 15A NCAC 02H .1021. Provide documentation of an approved stormwater permit issued by the Division of Energy, Mineral and Land Resources for all proposed built upon areas. 15. The application states that increased turbidity "may occur' as a result of the proposed project. Due to the sensitivity of downstream waters, provide a detailed contingency plan for large and/or prolonged precipitation events. Please note that duplicity and/or oversight should be addressed if the plan relies on mechanical equipment for downstream water quality protection and/or routine erosion control measures. Due to the sensitivity of downstream waters the Division requests that an approved Erosion Control Plan be secured prior to issuance of a 401 Certification. [15A NCAC 02H .0502(b)(3)] 16. Provide a lake dredging plan that clearly indicates how downstream water levels will be continuously sustained during dredging and during refilling of the lake. Please note that duplicity and/or oversight should be addressed if the plan relies on mechanical equipment for continuous minimum flow. 15A NCAC 02H .0506(d)] Pursuant to Title 15A NCAC 02H .0502(e), the applicant shall furnish all of the above requested information for the proper consideration of the application. Please respond in writing within 30 calendar days of receipt of this letter by sending all of the above requested information through this link: https://edocs.deg.nc.gov/Forms/Supplemental-Information-Form (note that the DWR# that is requested on the link is referenced above) or by sending one copy of all of the above requested information to the 401 & Buffer Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617.
