Re: Highcroft Village Outfall
Request for 404/401 Certification
W&R Project Number - 02100061.00
Dear Mr. Shern and Mr. McMillan:
On behalf of Highcroft Village Investors, LLC, we are requesting authorization from the USACE to use NWP
12 for the installation of a sewer line. We are also requesting 401-Certification from the NC-DWQ for the
impacts to jurisdictional waters and wetlands.
The proposed corridor is approximately 5600' in length. It originates on the western side of NC55
approximately 1 mile northwest of the intersection of NC55 and Green Hope School Road. The sewer line
will flow in a northwest direction where it will tie into an existing sewer line located south of the
intersection of Magalloway Drive and Cameron Pond Drive. The sewage will be transported to and treated
at the South Durham Waste Water Treatment Plant. The coordinates for the origin of the sewer line are
Latitude: 35.808775*N and Longitude: 78.876697'W in Cary, Wake County, North Carolina. The corridor
crosses tributaries which flow into Panther Creek (Cape Fear River Basin). The Water Quality Classification
for Panther Creek is: WS-IV; NSW, the Cataloging Unit for this site is: 03030002 and the Stream Index
number is: 16-41-1-17-3•
Project Purpose
The purpose of the proposed project is to construct a 12" sewer line that will service the Highcroft Village
project, as well as other future development adjacent to the sewer line. This section of sewer is a part of
the Town of Cary's Future Development Plan. As part of the approval of Phase IV of the Highcroft Village
development, the Town of Cary is requiring the Applicant to permit and construct the sewer line. Once the
sewer line is constructed, the Town of Cary will be reimbursing the Applicant for the cost of construction for
the portion of the outfall that are offsite from Highcroft Village.
Project History
Wetlands were delineated by Carolina Ecosystems in August 2010. Data forms and JD forms in support of
the delineation are included in the attachments.

The proposed permanent impacts include o.o63 acres of jurisdictional wetland impacts and 20 if of
perennial channel. The proposed o.o63 acres permanent wetland impacts will result from fill needed raise
the elevation of the sewer easement and to provide proper top cover for the sewer pipe. In order to create
the slope needed for the gravity sewer to function property, the sewer easement must be filled to raise the
grade approximately " - 5' at various areas along the easement. The proposed permanent wetland
impacts will result from the fill and backslopes necessary to stabilize the fill. The increased elevation of
the entire sewer line would have resulted in a rise in the loo year flood level, and the project would not
have been allowed by FEMA regulations.
The sewer line was designed to cross the channel (Sheet A) at an existing culverted stream crossing. The
existing crossing consists of two 70" CMP culverts and headwalls made of railroad ties which are failing.
The proposed 20 if of permanent stream impacts will result from the removal of the two existing 70"CMP
culverts and replacing them with three 54" RCP culverts, and construction of new headwalls. The
purpose for replacing the two 70" culverts with three 54" culverts is to lower the elevation of the culverts,
thereby lowering the elevation of the sewer. Using the existing 70" culverts would have increased the
elevation of the sewer at this point, resulting in an increase of elevation for the entire sewer line to
maintain the slope necessary for the gravity sewer to function property. An increase in elevation of the
entire sewer line would have required more fill and wider back slopes, causing additional wetland impacts.
The impacts are summarized on the overall impact map as well as the PCN form.
Avoidance and Minimization
Prior to design, the applicant requested that a detailed wetland delineation be conducted so that impacts
to wetlands and `waters' could be minimized. A preliminary review of the proposed corridor was also
conducted with project engineers and environmental scientist to identify site constraints (i.e. wetlands and
streams). Following this review, the alignment was redesigned to minimize impacts to wetlands/waters.
There are three stream crossings required for construction of the proposed sewer line. The sewer was
designed to utilize an existing culverted stream crossing (Sheet A) to minimize stream impacts at this
crossing to only 20 If. Also, aerial crossings have been designed for the two additional stream crossings
(Sheets B2 and C) and will avoid stream impacts at these crossings.
Due to the linear nature of the project, wetland impacts could not be completely avoided. The sewer was
aligned to minimize wetland impacts to the greatest extent possible, resulting in only o.o63 acres of
permanent wetland impacts.
During construction, silt fencing will be installed along the entire alignment to prevent sediment from
escaping and entering jurisdictional wetlands and/or Waters. During replacement of the culverts and head
walls at the northernmost stream crossing (Sheet A), coffer dams and pumps will be used so that work can
be done in the dry.

Indirect and Cumulative Impacts Analysis (DWQ)
As part of the review process, W&R is addressing the potential indirect & cumulative impacts that may
occur as a result of the installation of this sewer line. The Town of Cary has developed a comprehensive
plan that addresses these concerns. The proposed gravity sewer extension will ultimately provide sewer
service to numerous existing and proposed developments within the drainage basin, including the
proposed Highcroft Village subdivision, the proposed Fryar Tract PDD, the existing Highway 55 mini-storage
and the existing NC National Guard Armory, currently serviced by a temporary facility. Beyond these known
projects several other properties including some existing home sites on older septic systems, will
ultimately be served by this sanitary sewer main. The proposed project will discharge into an existing
gravity main that current being treated in the Southern Durham wastewater treatment facility. This is the
only facility utilized by the Town of Cary that returns wastewater to the Cape Fear River basin. Any
proposed development will be required to obtain 404/401 approval prior to construction. Any additional
area developed within the basin will meet federal and state regulations as well as the Town of Cary's very
stringent Jordan Lake watershed Stormwater Management and Stream Buffer Rules.
Mitigation
Since the proposed permanent wetland impacts (0.063 acres) are less than o.1o acre, and proposed
stream impacts are minimal (20 lf), there is no mitigation proposed for this project.
Please feel free to call if you have questions or require additional information.
Sincerely,

Troy Beasley
