Kayla Court Sanitary Sewer Aerial Maintenance
Dewberry Project No. 50022492
Dear Ms. Higgins:
Enclosed are five copies of a Pre - Construction Notification (PCN) Permit Application Package for the City
of Raleigh Kayla Court Sanitary Sewer Aerial Maintenance 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 "Kayla Court Sanitary Sewer Aerial Maintenance" consists of removing sediment and
debris upstream and downstream of a sanitary sewer aerial and stabilizing the stream bank in the
immediate vicinity of the aerial.
The construction described in this permit application results in approximately 1,200 square feet of Zone 1
buffer impact within a maintained utility easement and 40 linear feet of stream disturbance.
In addition to submission to NC DWQ, we are transmitting this PCN electronically to David Shaeffer at
the Army Corps of Engineers.
Please contact me with any questions regarding this permit applicat
Sincerely,
Dewberry Engineers Inc.

Attachment A —Additional Information
3d. Project Description
A temporary stream diversion will be installed so that all work will occur "in the dry." All work will take place with
access from the west stream bank. Trash and woody debris will be removed from the vicinity of the sanitary sewer
aerial (Approximately 10' upstream and 30' downstream of the aerial). Debris will be removed from bank to bank
(approximately 25' wide), returning the streambed to its original grade and matching the grade upstream and
downstream of the work area.
The west stream bank within the sanitary sewer easement (Approximately 10' upstream and 10' downstream of
the aerial) will be stabilized using geotextile and rip rap. All disturbed areas will be stabilized and reseeded
immediately upon completion of work. Conventional construction equipment (rubber -tired backhoe and dump
truck) will be used for the work. Photos of the existing site conditions and details are attached.
