Enclosed are five copies of a Pre-Construction Notification (PCN) Permit Application Package for the City of
Raleigh Dunn Road Sanitary Sewer Extension project. For your review we have enclosed the following:
• Five copies of the PCN Application Form
• Five copies of the Stream and Buffer Impacted Areas Drawing
• Five copies of Vicinity Map, USGS Map, and Soils Map
Only Buffer Rule approval is sought (no application fee is included). Approximately 91,500 square feet of
Zone 1 Buffer and approximately 95,000 square feet of Zone 2 Buffer will be impacted during construction.
Approximately 80,000 square feet of the Zone 1 impact is in the existing easement leaving 11, 661 square feet of
Zone 1 impact that will require mitigation. Since this is a sanitary sewer utility installation, Zone 2 impacts do not
require mitigation. The enclosed information documents and describes the anticipated impacts.
Please call with any questions regarding this project.
Sincerely,

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The sanitary sewer line in the areas of impacts is in the same location as the existing line to minimize impacts. The
replacement has been designed to disturb the minimal amount of area required to install the line. The area will be
returned to existing grade once the sanitary sewer is installed. The disturbed buffers will be re-vegetated with a buffer
seed mix based on recommendations in the Ecosystem Enhancement Guidelines for Riparian Buffer Restoration.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Contractor will minimize impacts to area by confining work area to limits of sanitary sewer easement and using erosion
control devices.

6f. Total buffer mitigation required: 34,983
6g. If buffer mitigation is required, discuss what type of mitigation is proposed (e.g., payment to private mitigation bank,
permittee responsible riparian buffer restoration, payment into an approved in-lieu fee fund). The City will purchase
riparian buffer mitigation credits from Forest Creek Mitigation Bank. Forest Creek Mitigation Bank states that they have
