RE: Pre -Construction Notification: Nationwide Permit 12 & General Certification No. 4133
West Neuse Interceptor Improvements
Wake County, North Carolina
Dear Mr. Phillips;
Carolina Ecosystems, Inc. (CEI), in conjunction with Black & Veatch, has prepared the
associated electronic Pre -Construction Notification (PCN) for the City of Raleigh Public Utilities
Department (CORPUD) in order to acquire a Section 404 Nationwide Permit 12 and a Section
401 Water Quality Certification No. 4133. This electronic PCN is being submitted for the
project along with corresponding figures, tables, impact exhibits, and engineering plans.
Additional details are provided below.
Project Description
CORPUD is planning sewer infrastructure improvements along the existing West Neuse
Interceptor (WNI) (Figure 1). The purpose of this project is to address critical needs of the WNI
system identified through the CORPUD wastewater master planning process. The project is
proposed to reduce the risk of system failure while also addressing population growth in the
existing service area.
The WNI serves a large portion of the greater Raleigh area, including the City of Raleigh, the
Town of Knightdale, and portions of Wake County. The proposed project consists of the
replacement of 25,000 linear feet of gravity sewer lines along the Neuse River. The existing 48-
and 54-inch diameter pipe will be replaced with 60- and 66-inch pipe. The pipes will be replaced
primarily in existing location, using temporary bypass pumping to maintain sewer service. In
seven locations, either parallel replacement or new location is proposed as detailed below in
Avoidance and Minimization and shown in the attached plans.
Clean Water Act Impacts
Total impacts to waters of the U.S. are 793 linear feet of temporary stream impacts, 8.27 acres of
temporary wetland impacts, and 0.57 acre of permanent wetland conversion. The permanent
conversion results from forested wetlands that are located within a 20-foot maintenance corridor
in two new alignment locations (Impact sites 15 and 25). Temporary wetland impacts would

Mr. Lyle Phillips Page 2 of 4
June 17, 2020
primarily result from clearing of the construction corridor for staging and bypass pumping, and
clearing and temporary excavation of wetlands within current utility maintenance corridor for the
installation of the new pipe. All disturbed wetland areas will be returned to pre -construction
elevations per the attached plans. Additional details of each impact are provided in the electronic
PCN, Impact tables, and Impact sheets. Note that the engineering impact drawings provide a
breakdown of forested and non -forested wetland impact within the permanent and temporary
easements for this project. Therefore, the permanent forested impacts in the plan set are not
correlated with the permanent wetland conversion impacts above.
Neuse River Riparian Buffer Impacts
Riparian buffers will be impacted during construction, but no impervious areas will be added as
this is a replacement of an existing utility line. Temporary disturbance to existing, cleared utility
corridor was deemed an existing and ongoing use under the Neuse Buffer rule. Riparian buffer
impacts to the Neuse River and several unnamed tributaries resulting from clearing within
existing easement or new easement would total 37,030 square feet of permanent Zone 1 impacts,
43,113 square feet of permanent Zone 2 impacts, 24,786 square feet of temporary Zone 1
impacts and 22,396 square feet of temporary Zone 2 impacts. All impacts are considered either
exempt or allowable per the Table of Uses, with the exception of 14,093 square feet of
permanent Zone 1 parallel impact, which would be classified as Allowable with Mitigation.
Following construction, all areas within riparian buffer zones will be returned to pre -construction
elevation contours and revegetated. A 10-foot corridor through buffer areas will require periodic
mowing for maintenance, but ground surfaces will be undisturbed.
Avoidance and Mitigation
Clearing in all forested areas outside of the existing and proposed CORPUD permanent utility
easement will be revegetated and no ongoing maintenance will occur in these temporary
construction easement areas. Cleared areas within the existing and proposed utility easements
will be revegetated but periodically mowed to maintain the easement. Mowing will be limited to
a 20-foot corridor in wetlands and 10-foot corridor in buffers.
The existing 60-foot CORPUD utility easement is being used to the maximum extent practical
for construction of this project. Due to the depth of the pipe and the need for bypass pumping to
maintain sewer service, an additional 30 to 40-foot temporary construction easement is required
along the project, as shown in the attached construction plans. In general, this additional
temporary easement is located on the upland side (away from the river) of the existing easement,
except where constraints such as steep slopes or existing infrastructure and housing prevent it.
Areas where new permanent wetland impacts were incurred outside of the existing City of
Raleigh easement are listed below.
- Impact W 15 (Station 61+50 to 93+50): The proposed utility line deviates from the
existing at this location due because removing the existing greenway bridge would be
cost prohibitive and would result in additional wetlands. The proposed alignment also
moves the sewer further from the Neuse River.
- Impacts W 17, W 18 and W 19 (Station 114+00 to 126+50): The proposed alignment was
designed to move the sewer further away from the Neuse River and limit impacts to

nearby streams. Additionally, utilizing the existing easement would require the removal
of another greenway bridge which would be both expensive, and impact the tributary
running beneath it.
- Impact W24 (Station 156+00 to 165+50): The proposed alignment in this location was
designed to avoid large floodplain wetlands along the Neuse River. Also, there is a large
concrete greenway bridge that spans this location. Removing the bridge would greatly
increase cost and impact more wetlands and streams in the area.
- Impact W25 (Station 191+00 to 196+00): The existing easement at this location runs
along steep slopes and is located between the greenway and residences. The proposed
easement was moved away from this location to better facilitate construction and avoid
any complications that could arise from construction in such close proximity to homes.
The new alignment would also form a more direct connection and utilize less pipe.
- Impact S14 (Station 199+50 to 207+00): The proposed alignment was designed to
construct the Neuse River crossing while maintaining the existing sewer service to avoid
bypass pumping over the river.
The crossing of the Neuse River is proposed to be constructed via open cut per the attached
plans. The crossing will be constructed in two segments with a cofferdam creating a dry work
area while maintaining downstream flow. The open cut construction is required due to the size
and slope of the pipe. To maintain the existing connections along the WNI, the replacement line
is at or close to the minimum allowable slope (0.05 to 0.06%). Bore or directional drilling
methods could not necessarily maintain this slope across the river for a pipe of this size.
The preceding information, along with the associated electronic Pre -Construction Notification,
stream and wetland impact tables, Vicinity map, USGS map, NRCS map, Impact Locations map,
Impact Drawings, and engineering plans are being submitted for your review of this project. A
copy of this application is also being provided to the NC Division of Water Resources for their
review and issuance of GC 4133 and Neuse Buffer Authorization.
If you have any questions or need additional information, please contact me at your earliest
convenience at [phone] or [e-mail].
Sincerely,
Carolina Ecosystems, Inc.

4h. Explain the purpose of the proposed project:*
A 2017 assessment 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 that services many nearby residents. Pipe diameter would be increased from existing 48- and 54-inch lines to 60- and 66-inch pipe to better facilitate the rapidly expanding
population of the area, and avoid 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 larger capacity sewer line. Where possible, the newsewer will be placed within the existing line's footprint.
Because of the depth required for the line to retain connections to the existing sewer 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. In wetland areas along the new alignment
sections, forested vegetation would be allowed to return except for proposed 20-foot maintenance corridor. 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.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
29.7MB
30.99MB
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.
Where possible, additional temporary easement is shifted away from the Neuse River, except in areas where the existing line is directly adjacent to
residential housing. Due to the required depth of the sewer, a 100-foot construction corridor is required to reach required depth to tie in existing
connections, and to allow room for bypass pumping of 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 lowflow conditions, allowing continued downstream flowto bypass the construction area. See
cover letter for additional information.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
During construction, the project will be reached from upland areas. Silt fencing and erosion control methods will be utilized. Following construction, soil
will be replaced and returned to original contours, and seeded to re -vegetate disturbed areas. A l areas beyond the current cleared easement, or new
20-foot maintenance corridor, will be allowed to return to forest vegetation.
