Enclosed are five copies of a Pre - Construction Notification (PCN) Permit Application Package for the City
of Raleigh Beaverdam Creek Bank Stabilization project. For your review we have enclosed five copies of
the PCN Application Form, Attachment A — Additional Information, USGS Quadrangle Map, site photos,
bank stabilization detail, and the $240.00 application fee
The project titled "Beaverdam Creek Bank Stabilization" consists of stabilizing a stream bank at two
locations in the proximity of a sanitary sewer line and manhole that have become eroded. This activity will
occur in sanitary sewer easements that have not been maintained in the last 10 years. Both sites are
located on unnamed tributaries of Beaverdam Creek
The total buffer impacts from both sites are 16,713 and 1,259 for zone 1 and 2 and 98 linear feet of stream
disturbance. The buffer disturbance is a result of easement clearing necessary to access the repair
location
Please contact me with any questions regarding this permit application.
Sincerely,
Dewberry Engineers Inc. ,

Attachment A— Additional Information
3.3.a Describe existing conditions and land use:
Marathon Lane Site (35 8408, -78 5611) stream bank erosion has exposed the side of a sanitary sewer manhole
that is located on an easement that has not been maintained within the last 10 years The land use in the vicinity of
the project is residential
Cobble Creek Site (35.8358, -78 5639) stream bank erosion has exposed and undercut the sanitary sewer line that
is located in an easement that has not been maintained within the last 10 years The land use in the vicinity of the
project is residential
3.3.d Explain the purpose of the proposed project
The purpose of the proposed project is to stabilize the stream bank in the immediate vicinity of a sanitary sewer
line and manhole that have become threatened due to stream bank erosion and to prevent further damage to
sanitary sewer infrastructure
3.3.e. Detailed project description including equipment to be used
Erosion of the stream bank threatens the integrity of a sanitary sewer line and manhole that are located in
easements that have not been maintained within the last 10 years Construction activity will consist of clearing the
sanitary sewer easements for access to the project location Rip -rap will also be placed along the eroded stream
bank and around the manhole to prevent further erosion in this area and to replicate the contours of the un-
eroded stream bank Stream bank stabilization details are attached Conventional construction equipment
(hydraulic excavators and dumptrucks) will be used The buffer disturbance will be seeded and mulched A pump
around or coffer dam will be used during construction to ensure all work occurs in the dry
D.1.a Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The placement of rip -rap will be limited to the area immediately surrounding the sanitary sewer line and manhole
and will not intrude into the stream A pump- around or coffer dam will be used during construction to ensure all
work occurs in the dry After construction is completed the disturbed area will be mulched and reseeded
