Can you verify the exit velocities shown for the dissipater basins? They are really high and will cause erosion. I'm thinking the entrance velocities were mistakenly inserted instead of the exit velocities.

I still have some additional requests/clarification. #1 Impacts for Site #4 are 766 linear feet. If the intermittent reach SM is 68 feet that would make the impacts for SL 698 linear feet; therefore, 698 feet of mitigation. Is that correct? Also for item #2, the dry basin and dissipater basins need to be included in the Stormwater Management Plan (SMP) and maintained. Please add these to the SMP as requested. Pursuant to Title 15A NCAC 02H .0502 (c), the applicant shall furnish all of the above requested information for the proper consideration of the application. If all of the requested information is not received within 30 calendar days, of receipt of this email, the Division will be unable to approve the application and it will be returned. The return of this project will necessitate reapplication to the Division for approval, including a complete application package and the appropriate fee. You may provide your response via email or mail to the address noted below.

Can you provide the following additional information for the Rutherfordton Bypass Individual Permit? On March 13, 2020, the Division of Water Resources (Division) received your application dated March 13, 2020, requesting a 401 Water Quality Certification from the Division for the subject project. Please provide the following information so that the Division can continue our review. 1. Site 4 includes 766 linear feet of stream impact for SL and an intermittent stream SM. Table 2 of the application includes the intermittent segment as part of the required mitigation for DWR. DWR does not require mitigation for intermittent streams. Please include the length of intermittent stream (SM) so that the Division can account for this. [15A NCAC 02H .0502(c)] Site 4 includes 766 linear feet of stream impact for SL and an intermittent stream SM. Table 2 of the application includes the intermittent segment as part of the required mitigation for DWR. DWR does not require mitigation for intermittent streams. Please include the length of intermittent stream (SM) so that the Division can account for this. [15A NCAC 02H .0502(c)] Robert, SM is approximately 68' long therefore on Table 2, Permit Site 4, the mitigable impacts for DWR are 758'. 2. Please provide the following items from the Stormwater Management Plan (SMP): a. Provide the Best Management Practices (BMP) page of the SMP that has the dry basin information. b. Provide the BMP page of the SMP that has the energy dissipater basin information. c. Provide the BMP page of the SMP that has the grass swale information for swales that meet the treatment swale criteria in the BMP toolbox. [15A NCAC 02H .0502(c)] These items are noted within the project summary of the SMP because they may provide some treatment benefit but were not designed specifically for stormwater treatment. These items were designed to attenuate flow and dissipate energy to avoid adverse impacts to downstream properties. NCDOT is not committing to maintain these items as stormwater devices as that is not their intention. That is why they are listed in the narrative and not in separate sheets of the SMP in accordance with our guidance. Thanks for your help and feel free to contact me if you need any clarification.
