(AID# SAW -2017-00718) Nationwide Permit 39/14 Verification and 401 WQC Request August 8, 2017 0 ? i 0 03 Ark/ 'k,�%'' 70 4�-6 Mr. Randolph, Per your direction, please find attached a revised Pre -Construction Notification for a Nationwide Pe ' 39 and 14 Verification request associated with the Thales Academy campus and adjacent Newtown Road improvements. This PCN is to replace the previous submitted NWP39 verification request. Documentation relevant to the delineation including dataforms as confirmed during your site visit was submitted with the prior request. Proiect Purpose The purpose of the project is to construct school facilities, including a thirty-six foot tall, two story educational building, playground facilities, bio -retention storm water treatment facilities, landscaping/buffer areas per ordinance requirements, driveways necessary for pick-up/drop-off child and public safety, and eighty-four parking spaces. Additionally, minor impacts associated with road improvements including turn lanes on Newtown Road are proposed to facilitate traffic flows and provide for public safety during school hours. Project Description Site grading and sediment and erosion control efforts will be completed in phases. Temporary erosion and sedimentation control facilities will be installed for use during site clearing and grading activities. These basins will be converted to permanent stormwater management facilities upon completion of the project construction activities. All appropriate sediment and control measures will be put in place according to the locally approved sediment and erosion control plan. NWP 39 impacts include the fill of previously impacted and man -created wetlands (abandoned agricultural area and borrow pit/mine in order to accommodate the needed facilities. Due to the natural topography of the site, it will be necessary to excavate and fill areas to the north of the site in CHRISTOPHER HUYSMAN WETLANDS & WATERS, INC.

HUYSMAN@GMAIL.COM JTAMPBANDY@GMAIL.COM order to provide the grades necessary to ensure safe parking facilities that meet local ordinance requirements and ADA functionality as well as other attendant features. Site access will be provided at the entrance to New Town Road at the south-eastern portion of the property, and will include the addition of turning lane. Impacts associated with these improvements are requested under NWP 14 and include fill and relocation of a road -side ditch/tributary and 0.004 acre of vegetated ditch to the south of Newtown Road. Avoidance and Minimization The site has been carefully designed to avoid impacts to regulated features where possible. Where impacts cannot be avoided, engineering analysis and design has been employed to minimize impacts to the maximum extent practicable while considering safety of the students attending the academy. Total impacts are less than one hundred and fifty feet to low quality tributary and less than one tenth acre of previously impacted or created wetlands. The project will utilize retaining walls in order to reduce wetland impacts and maximize the required parking facilities. Surface waters have been protected through local ordinance and post -construction BMP's. Mitigation The majority of the impacts to wetlands for the project occur to created wetlands (i.e. W1 wetland impacts as listed in the PCN located within a previously mined/borrow pit area) and maintained road- side ditch wetland (W3 wetlands associated with NW14). Total wetland impacts for the entire project are 0.119 acres. Additionally, the project is to employee extensive storm water control measures that will provide optimum treatment that likely exceeds that of the current capacity of the wetlands to be removed. In light of the predominantly low quality and anthropogenic origin or effects of the features to be impacted, it is assessed that the detrimental impact of the project on aquatic resources is no more than minimal; As such, the School has requested that the 1/10 acre mitigation threshold requirement be waived for these activities. NC WAM forms are attached as supporting data. Please contact us with questions or if additional information is necessary for the processing of this verification request.
