Triple Creek Bank Stabilization
Buffer Permit Application
Dewberry Project No. 50047595
Dear Ms. Higgins:
Enclosed are five copies of a Pre - Construction Notification (PCN) Permit Application Package for the City
of Raleigh Triple Creek Bank Stabilization project. For your review we have enclosed five copies of the
PCN Application Form, USGS Quadrangle Map, site photos, bank stabilization with detail, and the
$240.00 application fee.
The project titled "Triple Creek Bank Stabilization" consisted of stabilizing a stream bank at three
locations where severe stream bank erosion over time have put three manholes in imminent danger.
The construction described in this permit application will result in approximately 120 square feet of Zone
1 buffer impacts within a maintained utility easement and 120 Iinear feet of stream disturbance.
Please contact me with any questions regarding this permit application.
Sincerely,
Dewberry En ' rs Inc.
