4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: *
The project area consists primarily of the existing sanitary sewer and maintenance corridor, which runs parallel to the Neuse River. The corridor is primarily maintained in grasses and
some scrub areas with perimeter of the project area are forested where temporary construction easement is required. The Neuse River Greenway parallels and at times lies within the
existing easement. The surrounding area varies from recreational areas including the greenway and parks/ access, to residential and wooded areas.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?
Yes No Unknown
a

4f. List the total estimated acreage of all existing wetlands on the property:
7.421
4g. List the total estimated linear feet of all existing streams on the property:
374 (including 274 feet of tributaries and 100 feet of the Neuse River)
4h. Explain the purpose of the proposed project:"
A 2017 assessment of the West Neuse and Upper West Neuse Interceptors revealed faults in the existing sewer that could result in system failure unless corrected. The proposed project
would increase the capacity of the existing sanitary sewer to continue to provide wastewater disposal to the existing service area. The pipe diameter would be increased from existing 48
and 54-inch lines to 60-inch pipe to better facilitate current flows and anticipated expanding population of the area. This avoids the need for future upgrades or additional lines. See cover
letter for additional details.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The project would be a replacement of the existing sanitary sewer with a slightly larger capacity sewer line. The new sewer will be placed within the existing maintained corridor, parallel to
the existing line or (where constrained) in the existing lines footprint. Because of the depth required for the line to retain connections to the existing sewer collection system and the need to
maintain minimum slope along the pipe, a 40- foot temporary construction easement, in addition to the existing 60- foot wide utility easement, is required for a total 100- foot corridor width.
This will allow room for the continued service of the current line via bypass pumping, and for construction of the replacement line. All areas would be returned to pre -construction contours
and re -vegetated. The proposed 20- foot maintenance corridor would be contained within existing maintained sewer/greenway corridor with no permanent conversion of forested wetlands.
Typical construction equipment would be used including, but not limited to, excavators, dump trucks and other heavy machinery associated with utility line projects. See cover letter for
additional details.
5. Jurisdictional Determinations
5a. Have the wetlands or streams been delineated on the property or proposed impact areas?
Yes No O Unknown
Comments:
Delineated with West Neuse Interceptor in 2018/2019, PJD Request submitted in 2020, and
delineation rechecked/adjusted in 2023. See attached cover letter.
5b. If the Corps made a jurisdictional determination, what type of determination was made?*
Preliminary Approved Not Verified Unknown N/A
Corps AID Number:
5c. If 5a is yes, who delineated the jurisdictional areas?
Name (if known): Chris Hopper, Phil May, Brian Smith, Rob Crowther, Matt Harrell,
Preston Butler
Agency/Consultant Company: Carolina Ecosystems, Inc.

6. Future Project Plans
6a. Is this a phased project?*
Yes No
Are any other NWP(s), regional general permit(s), or individual permits(s) used, or intended to be used, to authorize any part of the proposed project or related activity?
The proposed project will be constructed at one time. The southern access corridor is shared with the West Neuse Interceptor project, currently in construction, in order to minimize
impacts. Other maintenance activities on separate segments of Raleigh's sewer system will be permitted, as required.

6i. Comments:
E. Impact Justification and Mitigation O
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The project maximizes the use of existing City of Raleigh utility easements to limit clearing of forested wetlands and previously undisturbed areas.
Additional temporary easement required for construction is shifted away from the Neuse River, except in areas where the existing line is in close
proximity to residential housing or other constraints. Due to the required depth of the sewer, a 100- foot construction corridor is necessary to reach the
required depth to tie in existing collection system connections, and to allow room for bypass pumping of the existing sewer as it is replaced. The Neuse
River crossing is proposed as open cut due to the minimum slope on the pipe requiring precise control of the crossing as well as the depth under the
river. A cofferdam (see plans) will be used to construct the Neuse River crossing in segments during low flow conditions, allowing continued downstream
flow to bypass the construction area. See cover letter and National Marine Fisheries Checklist (Attachment 1) for additional information.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
During construction, the project will be accessed from upland areas or existing temporary access roads. Silt fencing and other erosion control measures
will be installed and maintained in compliance with State and local requirements. Following construction, topsoil will be replaced and returned to existing
contours, and seeded to re -vegetate disturbed areas. All areas beyond the current cleared easement will be allowed to return to forest vegetation.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
Yes No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
There will be no permanent loss of Waters of the US associated with the project.
F. Stormwater Management and Diffuse Flow Plan (required by DWR) n
1. Diffuse Flow Plan
la. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
