Subject: City of Raleigh Public Utilities Department
Sawmill Road and Wellesley Park Sanitary Sewer Replacement
DWQ Project #17-0145
Dear Ms. Higgins:
Enclosed are five copies of a Pre -Construction Notification (PCN) Permit Application Package for the
City of Raleigh Sawmill Road and Wellesley Park Sanitary Sewer Replacement project including: site
location map, project description with photos, USDA soil maps, USGS topographic map, and the
$240.00 application fee. A complete set of construction plans has been prepared for this project and
is available if necessary, but is not attached to this application for simplicity.
The project will entail relocation of approximately 220 linear feet of sanitary sewer from Zone 1 to the
Zone 2 buffer. Existing sanitary sewer in the Zone 1 buffer will be abaondoned in place. The work will
result in a temporary stream impact of approximately 50 linear feet.
Please contact me with any questions regarding this permit application.
Sincerely,
AECOM Technical Services of North Carolina, Inc.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
Ia. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Stream and buffer disturbances will be the minimum necessary to allow for abandonment of existing sewer and relocation to Zone 2. Buffers will
be restored to original contours and stabilized upon completion of the project.
I b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Work areas will be confined to the minimum extent necessary to perform the work. Disturbed areas will be perpendicular to the buffer to the
extent possible. Erosion control devices and measures will be installed prior to construction and work will be scheduled during a dry period.

Sanitary Sewer Relocation - Sawmill Road and Wellesley Park, Raleigh, Lat. 35.883735, Long. -78.671174
A sanitary sewer manhole and sanitary sewer mains and service lines ranging in size from 6 -inch PVC to 10 -inch ductile
iron are located within the Zone 1 stream buffer of an unnamed tributary to Mine Creek. The streambed width is
approximately 10 LF. As a result of erosion, some of the sanitary sewer infrastructure in the area is exposed and/or
unstable.
Proposed work consists of the following:
Approximately 220 linear feet of sanitary sewer will be relocated from Zone 1 to the Zone 2 buffer.
The existing pipe parallel to the stream within Zone 1 will be abandoned in place with flowable fill.
One existing manhole within the streambed will be removed and the bank stabilized.
Exposed DIP at the stream crossing will be replaced with restrained joint DIP and will be lowered so that it is no
longer exposed in the streambed.
The total temporary stream disturbance associated with this work will be approximately 50 linear feet. The total new
permanent buffer impacts associated with the relocation will be approximately 1,000 sq ft in Zone 1 and 2,800 sq ft in
Zone 2; however, abandonment and relocation of infrastructure in Zone 1 will remove approximately 3,000 sq ft of
current Zone 1 impact.
Erosion control measures such as silt fence, construction entrance, and clewatering will be used to prevent
sedimentation during construction. Impacted areas will be stabilized and revegetated.
