Good Afternoon Chris and Sue, On behalf of the applicant, please find the below responses and attachments. Please let me know if you require additional information. Thank you. USACE Comment 1) The previous permit verification authorized the loss of 0.247 acre of Waters of the United States (combined stream (0.004 ac) and wetland (.243 ac) loss). In addition to the temporary/permanent stream crossing(s) requested, stream impacts are show underlying future home sites. Please clarify why mitigation for stream impacts is not proposed? A conceptual build -out exhibit with future impacts estimated would be helpful. Applicant Response: The attached overall site plan for future phases was conceptually designed to the Town of Swepsonville development ordinance requirements to obtain zoning approval in 2019 and for NWP Verification for Phase I impacts in 2020. Impacts to streams, outside of those proposed within this application, are not conceptually proposed for future phases compared to the USACE concurred stream/wetland delineation (attached). It is the applicant's understanding that the Town of Swepsonville is considering updates to their residential development ordinance, specifically as it relates to the implementation of residential cluster development, which is currently prohibited. Currently, the development ordinance will allow for 8,000 square foot residential lot minimums, whereas typical residential cluster development ordinances in similar localities can allow minimums of 5,000 square foot residential lots. If the Town of Swepsonville updates their development ordinance to allow for cluster development or smaller residential lots prior to the developer proceeding with future phases, then proposed future phases will be re- designed to avoid conceptual designed impacts to Pond PF and Wetland WF, thus allowing for the overall project to meet the current permitting requirements of Nationwide thresholds. If the Town of Swepsonville does not update their current planning regulations for residential developments to allow for smaller residential lot footprints prior to the developer moving forward with future phases, then the applicant has alternative options to utilize green space/common elements to the south of future phases not currently being shown as developed (i.e. green space immediately south of conceptually designed lots 190-220). This alternative option would also allow the re-design/re-location of lots to avoid conceptual impact to Pond PF and Wetland WF, such that the overall project could be permitted under current Nationwide Permitting thresholds. The applicant is committed to exhausting all development and design options as described above to meet the necessary number of residential lots for the overall project to be financially viable while avoiding an Individual Permit and/or potential mitigation thresholds for streams. The applicant has designed the cumulative net loss impact to streams from the first two phases below Nationwide Permitting stream mitigation thresholds and has conceptually demonstrated there will not be additional impact to wetlands that would exceed the current Nationwide Permitting mitigation threshold. Therefore, stream mitigation is not proposed. USACE Comment 2) Impact locations aren't clear on the exhibits provided. It appears the temporary and permanent stream crossings would occur in the same location; please confirm. The upstream invert elevation of the temporary pipe is more than a foot higher than the upstream invert of the permanent pipe, so if these would be in the same footprint it is confusing. Applicant Response: The attached PCN and impact drawings have been updated to reflect that the applicant no longer proposes the use of a temporary stream crossing. USACE Comment 3) The total stream impact of the currently proposed project, 41 linear feet (Stream Impact Table), doesn't match other information shared. Can you please confirm this is correct? Applicant Response: The attached PCN has been updated to reflect proposed stream impact amounts. USACE Comment 4) The application states that the temporary crossing would be used for six to nine months and removed prior to installation of the permanent culvert. Temporary discharges cannot be placed in waters for more than six months without specific written permission from the Corps. It's conceivable that timelines or availabilities may factor into the reasoning, but can you elaborate on the need for this approach? What duration of time is anticipated between removal of the temporary pipe, and installation of the permanent one? Applicant Response: The attached PCN and impact drawings have been updated to reflect that the applicant no longer proposes the use of a temporary stream crossing. USACE Comment 5) We appreciate the consideration of not burying the culvert due to slope and bedrock, but the proposal doesn't meet the condition referenced in your response to NCDWR ("Culvert burial is not required for structures less than 72-inch diameter/width, where the slope of the culvert will be greater than 2.5%, provided that all alternative options for flattening the slope have been investigated and aquatic life movement/connectivity has been provided when possible (e.g., rock ladders, cross vanes, sills, baffles etc). Culvert burial is not required when bedrock is present in culvert locations."). The slope is less than 2.5% and dual 66-inch culverts aren't consistent with the 72-inch threshold. If a photograph or supporting design information is available to document our approval based on bedrock it would be helpful. What considerations were made to provide for aquatic life passage? Applicant Response: See attached photograph documenting exposed rock within the proposed permanent stream crossing location. Therefore, we request written waiver of NWP 29, condition 9, a.

Sue —based on the scaled cross section (Impact Drawings 4 of 4, Page 19 of PCN), the culvert slope is at or near 2.5%. The proposed culvert was designed to meet NCDWR GC 4256 Condition 11, paragraph 3 in addition to NWP 29, condition 9, a. Also noteworthy, based on our field visits and familiarity with the site, there are exposed rock outcrops at grade within the proposed culvert footprint.

Further, an AJD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to make an official determination whether geographic jurisdiction exists over aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is practicable. This PJD fmds that there "may be" waters of the U.S. and/or that there "may be" navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the review area that could be affected by the proposed activity, based on the following information: SUPPORTING DATA.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The applicant has designed the remaining portions of Phase II to avoid other impacts to streams and wetlands. The stream crossing is located in an area of an existing culvert that previously impacted 12 linear feet (67SF) of stream channel. The proposed stream crossing has been designed to cross the stream in a relative straight area that is free of meanders and absent of wetlands. There are approximately 4,674 linear feet of stream channel, 0.50 acres of wetlands and 12.26 acres of ponds located on the site. The ponds, wetlands and remaining 4,536 linear feet of stream channel are being avoided. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The clearing limits will be staked and sediment erosion control devices will be used. Temporary coffer dams will be installed upgradient of the proposed road crossings. During construction, water will be pumped around the construction footprints. Appropriate stream bank protection will be provided in the channel during road construction and all excess excavated material will be immediately removed from the stream bank/road crossing area. Upon completion of the culvert installation, the temporary sand bag coffer dam will be removed and flow will be diverted through the culvert. Following culvert installation, disturbed banks will be restored to similar pre -construction conditions, matted and seeded/live staked. 2.
