The slope of the fill above the retaining wall is 2:1. I have included the Fine Grading Plan and a bulletin showing the impacted wetlands (red). 2. Attached is Sheet C931. Erosion Control Notes and Construction Sequence are included on this sheet. Let me know if this will address their comments. Michael Cain, P.E. Civil Design Concepts, P.A.

The slope of the wetland fill 2. The construction sequence and erosion control notes on the project plans. Eric Eric Romaniszyn Senior Scientist EnviroScienceInc.com “Excellence in Any Environment” C. 865‐406‐1281 From: Winston, Joey <joey.winston@ncdenr.gov> Sent: Friday, March 10, 2023 9:38 AM To: Eric Romaniszyn <eromaniszyn@enviroscienceinc.com> Subject: Request for Additional Information, Mitchell County Schools, Mitchell County (DWR #20220398v3) [EXTERNAL EMAIL ‐ Please use caution] Mr. Romaniszyn, On February 1, 2022, the Division of Water Resources (Division) received your application requesting a 401 Water Quality Certification from the Division for the subject 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. The application did not include a discussion of the measures taken to avoid or minimize the proposed impacts to wetlands through project design. Please include a narrative of the design choices made with regard to wetland impacts, including a discussion of why impacts cannot be further reduced or avoided. [15A NCAC 02H .0506(b)(1)] Two school entrances were designed to better manage traffic flow and for emergency access. The eastern access road along Ledger School Road was placed at its current location to meet those requirements and avoid placing it near the Hwy 226 intersection that would result in additional traffic concerns. The location of this access road was also designed around the wetland locations to avoid additional impacts. The school was designed around a central corridor with classrooms on each side and two stories tall. This section narrows the school building dimension and creates the smallest footprint possible. The parking lot was positioned to parallel the front of the school with minimal islands/medians to keep the parking as close to the school as possible, while providing the NCDOT required staging length for pick-up and drop-off. A 13-foot retaining wall was designed to minimize wetland and stream buffer impacts. 3 Moving the campus west would elevate the building and make the bus driveway (north side of building) steeper. The current design grade is currently at 5-6% which is comfortable for bus operations. Moving west would also take the top of the slope much closer to adjacent parcels and a preserved vegetative buffer. The required fire access road also restricts a westward adjustment, as this grading abuts the parcel in the southwest corner while still allowing flat space between the access road and the building for outdoor play space. 2. The project plans do not include details of the proposed wetland fill. Please provide a detailed plan of the proposed wetland impacts, including design considerations for the stability of the fill material to ensure additional impacts will not occur. [15A NCAC 02H .0502(a)(9); 15A NCAC 02H .0506(b)(3)] The engineer does do not currently have a detail of how this will be completed, but the project has earthwork and stabilization specification that will require the Contractor to properly construct a foundation for this fill and stabilize the slope. The Project has also developed construction sequence and erosion control notes on the project plans. The engineer can provide these specifications if that will suffice. 3. The project plans do not include the proposed temporary impact to the stream for utility installation. Please include this in project plans. [15A NCAC 02H .0502(a)(9); 15A NCAC 02H .0506(b)(2)] The temporary impact would occur under the permanent impact of the culvert at the Ledge School Road access drive. I apologize for not explaining that better in the narrative. Would you still need the plans if the text was changed to this? “The development will connect to existing municipal water and sewer utilities along Old Ledger Road on the eastern project boundary. These connections will occur under the new school entrance road and may require stream crossings (temporary impacts) due to the location of the stream channel, depending on final site design. If so, the utility lines will be installed “in-the-dry” under the stream bed via open cut coinciding with installation of the permanent culvert impact (see Attachment B, Impact Map).” 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. Please provide your response by April 7, 2023. If all of the requested information is not received, the Division will be unable to approve the application and it will be denied as incomplete. The denial of this project will necessitate reapplication to the Division for approval, including a complete application package and appropriate fee. Please let me know if you have any questions.
