Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to report.spam@nc.gov Good Afternoon David, Please find the attached and below responses to your request for additional information. Please let me know if you require more information. Thanks. USACE Comment 1) Given the relatively steep slope (2.5%) of the proposed culvert, we are concerned that this stream would be subject to headcutting above the proposed culvert due to the proposed V invert burial. Please confirm with NCDWR regarding whether or not culvert burial is required/advisable in this situation. If burial of the culvert pipe is not advised, please redesign accordingly and update the PCN and applicable plansheets; Applicant Response: See attached updated PCN and impact exhibits. USACE Comment 2) We have scaled the proposed culvert on the plans provided and determined stream impacts to be different than those reported in the text of the PCN/plans: A. Given that the culvert outlet would not occur directly in line with the existing stream channel, a portion of the stream channel below the culvert would be cut off from direct stream flow. This does not appear to have been accounted for in the reported permanent loss stream impacts. If a straight line is drawn along the center of the culvert from the upstream point where the headwall intersects the stream centerline to the point where the straight line intersects the stream centerline below the culvert (see attached, blue line), the impacts along the centerline of the stream (see attached, red line) scale to approximately 114 I.f. Please update the PCN (including the mitigation proposal) and plans accordingly; Applicant Response: See attached updated PCN and impact exhibits. USACE Comment 2) Any additional impacts in the rip rap footprint not covered above would be considered rip rap only, i.e. permanent impacts but no permanent loss; Applicant Response: See attached updated PCN and impact exhibits. USACE Comment 3) Given that the proposed culvert would intersect the downstream portion of the stream channel at a skew, please provide additional stream bank protection to ensure scour does not occur along the stream bank downstream of the proposed crossing. Please updated the project plans accordingly, and provide a profile/cross-section clearly showing the proposed stream bank protection (see attached Profile Example); Applicant Response: See attached updated PCN and impact exhibits. USACE Comment 4) The proposed wetland impact includes fill in the top half of a small narrow wetland. Given the small size of the wetland in question, and the fact that the drainage area for this wetland would be rerouted due to grading in the upland portion of the site, the Corps would consider the remainder of this wetland as an indirect impact. As such, the wetland loss due to direct and indirect impacts would include the entirety of Wetland WC, or 640 sq. ft. (0.015 acre). Applicant Response: See attached updated PCN and impact exhibits.

Describe the overall project in detail, including the type of equipment to be used: The overall project consists of the development of Phase 2 of the Cambridge Park residential subdivision. At this time, Phases I A and 1 B have been constructed and Phase 2 has been fully designed. With the exception of Phase 7, the remainder of the residential subdivision has been conceptually designed. At this time, Phase 7 has not been conceptually designed. With the exception of Phase 7, it appears the remainder of residential subdivision can be developed without future impact to WoUS outside of those proposed in this application. The applicant understands that additional impacts associated with the remaining phases of the proposed subdivision will be cumulative for purposes of permitting and mitigation requirements. Phase 2 of the site consists of developing the site with residential lots, one stormwater retention pond and associated roads. Access roads and residential lots will result in impact to streams and wetlands. To facilitate development of the site, clearing and grading the site is necessary. Graders, haulers, excavators and other heavy equipment will be used during site construction. 4. Jurisdictional Determinations 4a.

Future Project Plans 6a. Is this a phased project? ® Yes ❑ No 6b. If yes, explain. The applicant obtained USACE NWP Verification and NCDEQ-DWR 401 WQC for the first two Phase of Cambridge Park, a residential subdivision. Based on conceptual designs, additional impacts to WoUS are not anticipated in the remaining phases, with the exception of Phase 7 which has not been designed at this time. The applicant is aware that impacts are cumulative for permitting and mitigation thresholds for potential future impact to WoUS. However, the applicant is not ready to proceed with Phase 7 of the subdivision or permit potential impacts associated with Phase 7 at this time. Establishment of a timeline for future phases of development will be dictated by market conditions at that time. The applicant acknowledges that the current and future development must occur in a manner to avoid and minimize impacts to WoUS. Page 4 of 12 PCN Form — Version 1.3 December 10, 2008 Version C.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The road crossing location was selected in an area of stream that is relatively straight with few meanders and will cross as near to perpendicular as possible given field and design constraints. The applicant has further demonstrated avoidance and minimization of stream impacts by proposing to construct approximately 5.5 feet tall culvert head/end walls. Furthermore, the Applicant has designed rip -rap stabilization measures to be keyed into existing grades of stream bed and banks, thus reducing the net loss of stream. There are approximately 9,020 linear feet of stream channel and 0.22 acres of wetlands located on the site. Phase 2 has been designed to avoid the remaining 8,896 linear feet of stream channel and 0.13 acres of wetlands. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The clearing limits will be staked and silt fence will be used. A Temporary coffer dam will be installed up -gradient of the proposed road crossing. During construction, water will be pumped around the construction footprint. Appropriate stream bank protection will be provided in the channel during construction and all excess excavated material will be immediately removed from the stream bank crossing area. Upon installation of the culvert, the temporary sand bag coffer dams will be removed and flow will be diverted through the culvert. Disturbed banks will be restored to similar pre -construction conditions, matted and seeded/live staked. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.
