Additionally, a separate request was received from the U.S. Fish and Wildlife Service (USFWS) on September 13, 2023 recommending a rough -leaved loosestrife survey recommendation email received on September 13, 2023. As USFWS consultation is relevant to this permit application, a brief summary of our response to the USFWS and a copy of our species survey is included for your reference. The impacts maps shown in Appendix A have been revised to include the Relatively Permanent Waters (RPWs) that were shown in the Preliminary Jurisdictional Determination (PJD) SAW-2022-01670. Proposed impacts to these features have been added as Impacts 4 and 5, totaling approximately 0.107 acres. All other impact amounts remain the same as reported in the Pre -Construction Notification (PCN) application dated August 25, 2023. A memorandum detailing the rough -leaved loosestrife survey conducted on September 19, 2023 is included in Appendix B. The comments are outlined below in italics and are grouped by agency, with USACE comments in blue and USFWS comments in green. Our response is below each comment. USACE Comments 1. Two Non -wetland waters are shown on the delineation and appear to be impacted. There are no impacts shown for these features. ENGINEERING I DESIGN I TECHNOLOGY The two non -wetland waters features were determined to be RPWs and have been added to the impact maps as Impacts 4 and 5. Please see attached Appendix A - Updated Impact Maps. 2. What is the reason for requesting an 18 and 29 when it appears that just 18 would work bases on current plans. Please clarify. We originally pursued an 18 and 29 due to Impacts 1 and 2 being associated with stormwater discharge. We will continue to pursue 18 and 29 because we are above a cumulative 0.10 acre of impacts with the addition of Impacts 4 and 5. 3. Wetland Impact 2A and 2B will need some more justification why these cannot be avoided. Can the building be built without impact to these areas? If it is just to have a square lot and yard are then this would not be minimization or avoidance. This area between Impacts 2A and 2B is being proposed as open space to minimize the wetland impacts that would have otherwise resulted if this area was designed as a residential lot. Lot 118 was also shifted further south to expand the open space area to be larger than the residential lots and lots 118 and 119 will be graded to the minimum pad width to minimize impacts. Typically, the 3:1 side slope begins after the lot's side property line, but we are proposing to begin the side slope within the lot to minimize grading impacts. This is the minimum we can go to ensure long term stability of the houses on these lots, and lot count has been reduced as much as practicable for the project to remain feasible. 4. Wetland Impact 3 needs justification. Why can the swell coming from the road not cross the wetland and stop before getting into the wetland. Wetland Impact 3 is required to construct an outfall swale that will allow for positive drainage from the proposed roadway culvert into the wetland. There is a depression between the culvert and the wetland that would pool and hold water if the culvert were to directly drain towards the wetland because the wetland is at a higher elevation than the culvert and existing depression. The outfall swale will allow for water to move from the existing RPW on the opposite side of the road to the wetland without causing drainage issues. If the water cannot drain properly to the wetland, the residential lots could be affected. The location where the outfall swale is proposed to drain to the wetland is in a lower elevation that will allow for positive drainage. The culvert cannot be raised in order to achieve minimum cover over the pipe before the roadway pavement. The swale has been bend around to the west to try and limit wetland impact to the shortest crossing. USFWS Comments Regarding the determination for Rough -leaved loosestrife, do you have any information regarding how often the utility right-of-way is maintained? Based on the photo and maintenance of typical easements through nondeveloped areas, to me it appears it i maintained as early succession vs 'yard like. "Also it appears that there are several wetland/stream areas that the right-of-way crosses on the property. If this is so, are there areas that are moist or seasonally saturated soils? If the area is maintained as early succession, and there are moist or seasonally saturated soils, I would recommend surveys be conducted for Rough -leaved loosestrife during the appropriate survey window by someone familiar with the plant. Timmons Group conducted a plant survey for rough -leaved loosestrife on September 19, 2023. Based upon the absence of individuals of rough -leaved loosestrife observed during the onsite survey and the lack of documented occurrences within 1-mile of the project, it is the opinion of Timmons Group that the proposed project will have no effect on rough -leaved loosestrife. Please see attached Appendix B - Rough -Leaved Loosestrife Survey Memo for more details. The Rough - Leaved Loosestrife Survey Memo was sent to the USFWS on October 19, 2023. It should be noted that the existing electrical lines within the utility corridor will be relocated. The relocation was previously planned and is being handled by Brunswick Electric as part of a larger project. Therefore, the projects are single and complete projects with independent utility, and this project addresses all jurisdictional impacts relating to the residential development. Please review the updated Impact Maps and Survey Memo and contact Emory Quillian at 919.348.8841 or emory.guillian(cDtimmons.com if additional information is required.

Box 33726 Raleigh, NC 27636-3726 October 16, 2023 P 919.866.4951 F 919.859.5663 www.timmons.com Re: Rough -Leaved Loosestrife Survey Results, Hall Tract, Bolivia, Brunswick County, North Carolina. Dear John Ellis, On behalf of DR Horton, Inc., please find the enclosed rough -leaved loosestrife (Lysimachia asperulaefolia) survey results for the Hall Tract site (also referred to as the Site). Per a request from your office on September 13, 2023, Timmons Group personnel completed an plant survey for rough -leaved loosestrife individuals on September 19, 2023 within an agreed upon area of potentially suitable habitat consisting of early successional vegetation within the maintained utility right-of-way (ROW) easement in areas of moist or seasonally saturated soils.. Due to the absence of observed individuals and the lack of documented occurrences within 1-mile of the Site, it is the opinion of Timmons Group that the proposed project will have no effect on rough - leaved loosestrife. Site Description The Site is located within the Coastal Plain Physiographic Province and encompasses approximately 135.88 acres in Bolivia, North Carolina within Brunswick County. The Site consists primarily of forested area with approximately 12 acres of maintained open area associated with agricultural uses. There are two palustrine forested wetlands totaling approximately 79 acres, two relatively permanent waters totaling approximately 1,199 linear feet within the Site. There is a maintained utility ROW easement totaling approximately 3.5 acres in the northern portion of the Site. Lockwoods Folly River borders and then transects the southern perimeter of the Site within the wetland area. In addition, approximately 20 acres of the forested area appears to be a planted pine forest with an approximate age of 20 years. The Site is bound by forested and residential area to the north and west, and by forested areas to the south and east. The Site is located within the Scotts Branch-Lockwoods Folly River subwatershed (Hydrologic Unit Code [HUC] 030402080104) in the Lumber River Basin. The Site drains to the south via surface flow and unnamed tributaries to Lockwoods Folly River, which has a NC Division of Water Resources (DWR) Stream Index Number of 15-25-1-(1) and a Stream Classification of C; Sw. Based on a review of the Site and a discussion with the U.S. Fish and Wildlife Service (USFWS), it was determined that one potential area of suitable habitat totaling approximately 3.5 acres is located within the Site: an early successional maintained utility ROW easement that contains portions of moist or seasonally saturated soils. The remainder of the Site consists of heavily forested, recently cleared, maintained agricultural, and shaded areas, which do not constitute potentially suitable habitat for rough -leaved loosestrife. Assessment Methods Timmons Group conducted a plant survey for rough -leaved loosestrife on September 19, 2023 during the species USFWS optimal survey window which occurs from mid -May through September. Prior to the survey, Timmons Group visited a known population of rough -leaved loosestrife in Winnabow, NC. The presence of individuals was confirmed by Dale Suiter on September 18, 2023 and Timmons Group on September 19, 2023. Identifying characteristics of the species, suitable habitat conditions, and plant communities were noted during the site visit of the reference population. The plant survey consisted of walking the entirety of the wetlands and streams located within the utility ROW easement and walking the rest of the approximately 3.5-acre easement in transects spaced approximately 20-ft apart. The survey area was focused on the area of potentially suitable habitat on -Site confirmed with the USFWS. Survey Findings Rough -leaved loosestrife generally occurs in the ecotones or edges between longleaf pine uplands and pond pine pocosins in dense shrub and vine growth on moist to seasonally saturated sands and on shallow organic soils overlaying sand. Occurrences are found in such disturbed habitats as roadside depressions, maintained power and utility line rights -of -way, firebreaks, and trails. The species prefers full sunlight, is shade intolerant, and requires areas of disturbance (e.g., clearing, mowing, periodic burning) where the overstory is minimal. It can, however, persist vegetatively for many years in overgrown, fire -suppressed areas. Blaney, Gilead, Johnston, Kalmia, Leon, Mandarin, Murville, Torhunta, and Vaucluse are some of the soil series where the plant occurs. The results of the on -Site survey found no individuals of rough -leaved loosestrife. The utility ROW easement on -Site was observed to primarily consist of tall goldenrod (Solidago altissima), sawtooth blackberry (Rubus argutus), dog fennel (Eupatorium capillifolium), sapling sweetgum (Liquidambar styraciflua), and common wormwood (Artemisia vulgaris). The wetlands, streams, and relatively permanent water areas within the power utility easement on -Site were observed to primarily consist of tall goldenrod, sapling sweetgum, deertongue (Dichanthelium clandestinum), netted chain fern (Woodwardia areolata), three-way sedge (Dulichium arundinaceum), eastern woodland sedge (Carex blanda), leathery rush (Juncus coriaceus), and broadleaf cattail (Typha latifolia). Conclusion Based upon the absence of individuals of rough -leaved loosestrife observed during the on -Site survey and the lack of documented occurrences within 1-mile of the Site, it is the opinion of Timmons Group that the proposed project will have no effect on rough -leaved loosestrife. We request an "agreement of findings" from the USFWS for the Hall Tract Site. For additional information, please contact Emory Quillian at the email address listed above.
