Bank Stabilization
Buffer Permit Application
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 Hallvvvgate 3E%es-M' 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 " " consists of stabilizing a stream bank parallel to a
sanitary sewer that has become eroded, resulting in exposed clean -out piping. This activity will occur in a
sanitary sewer easement that has not been maintained in the last 10 years.
The construction described in this permit application will result in approximately 6,5o6 square feet of
Zone 1 and 416 square feet of Zone 2 buffer impacts within an unmaintained utility easement and 50
linear feet of stream disturbance.
Please contact me with any questions regarding this permit application.
Sincerely,
Dewberry Engineers Inc.
