Ms. Tasha Alexander Raleigh Regulatory Field Office US Army Corps of Engineers 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 201 80572 3040 NC Hwy 42 West; Clayton, NC 27520 P:919-359-1102 — F:919-585-5570 April 23, 2018 RE: Pre -Construction Notification: Clean Water Act Section 404/401 Approvals and Neuse River Riparian Buffer Authorization, Meadows of Banks Subdivision Wake County, North Carolina Dear Ms. Alexander; Carolina Ecosystems, Inc., on behalf of the Perry Brothers Construction and Stewart -Proctor, has prepared the attached Pre -Construction Notification (PCN) for the above referenced project for a Clean Water Act (CWA) Section 404 Nationwide Permit (NWP) 29, its corresponding Section 401 General Certification 4139, and a Neuse River Riparian Buffer Authorization. The site is located along Banks Road in southern Wake County. The project would help to meet housing demands for residences in the rapidly growing Triangle region of North Carolina. The attached PCN form provides information for your use in review of unavoidable impacts to streams, wetlands, and riparian buffers. Two unnamed tributaries of Mills Branch in the Neuse River Basin occur on the property. Impacts would include a perpendicular road crossing of Stream SA, including portions of two of its associated wetlands and riparian buffer. A portion of stream SB would also be filled, and two areas of its buffer graded to accommodate a stormwater BMP. No portion of the BMP's treatment footprint would overlap these resources. Access to the site would be provided via extension of Berkshire Lane on the site's west. A stub road on the east is required by the county, but no plans to develop future phases exist. Future home sites will be limited to 7,000 square feet of impervious surface in perpetuity, but overall imperviousness is not known. Eighteen percent is used in this application as an estimate, but is likely an overestimate. Wake County will review and approve stormwater plans for the project. Avoidance and Minimization A pump around would be utilized to install the culvert and road crossing of Stream SA and temporarily dewater 165 feet of Stream SA (Attached Sheet C-5 and impact Figure 1). Within this area, three 80 -foot long, 60 -inch diameter culverts would be installed and impact 82 linear feet of stream. Each would be installed to 1 -foot below natural stream bed. The stream on the downstream end of these culverts would be stabilized with rip -rap, compressed into natural bed elevation, for 41 linear feet. Meadows of Banks April 23, 2018 Page 2 of 3 Stormwater collected at the road cul-de-sac would be diverted to Wet Detention device #2 in the northwestern portion of the site. The original plan included a diversion ditch berm wetland WJ, but the design was modified to pipe under this feature with no permanent impact to this wetland. Stormwater would be directed through -an 18 -inch reinforced concrete pipe under the wetland (Sheet C-5). A temporary wetland impact of 280 square feet would accommodate installation. During the PJD visit with the USACE, Stream SB was extended approximately 100 feet beyond what the NCDWR had buffered and resulted in a portion of the stream extending into the treatment footprint of Wet Detention Device # 1. To preserve soils suitable for septic systems, maintain the minimum storage volume required by Wake County, and minimize impacts to surface waters, the device was shifted so that only a portion of its berm would impact Stream SB. The minimized impact to this feature would now total 24 linear feet (Impact Figure 2). Two buffer impact areas, totaling 0.28 acre are associated with this property. The impacts would occur in Zone I and Zone II as part of the perpendicular road crossing over stream SA (0.26 acre, Impact Figure 1), and grading and revegetating a portion of zone II to install a BMP Berm adjacent to stream SB (0.02 acre, Impact Figure 2). Level spreaders are proposed on the south side of stream SA's buffer along the proposed road crossing (Sheet C-3). Each would be located outside Buffer Zone II and ensure diffuse flow of stormwater along the proposed road through the buffers. Sediment and erosion control measures would be implemented according to NC requirements, and approved by NCDEQ prior to implementation. Jurisdictional areas adjacent to construction areas would be clearly marked with protection fencing or other similar method to avoid inadvertent encroachment. Copies of permits and impact areas would be provided to the prime contractor and all subcontractors working in or near jurisdictional areas. Land clearing would take place along with installation of erosion control devices. Construction would be accomplished using typical equipment including excavators, backhoes, and dump trucks. Additional equipment may be used as required. A Tier 1 search of the NC Natural Heritage Data Explorer found no records of federally protected species on or near the project. Their report is attached. The preceding information, along with the enclosed Pre -Construction Notification form, Vicinity map, USGS map, Jurisdictional Features map, impact drawings, and erosion sediment control plan sheet C-3 are being submitted for your review of this project.

Clayton, NC 27520 RE: Meadows of Banks S/D Dear Christopher Hopper: Secretary Susi H_ Hamilton NCNHDE-5665 The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. A query of the NCNHP database, based on the project area mapped with your request, indicates that there are no records for rare species, important natural communities, natural areas, or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached 'Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists and is included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the project area, if any, are also included in this report. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement, or Federally -listed species are documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rodney.butlerD-ncdcr.aov or 919.707.8603.
