long by 10 -foot wide areas would be disturbed to stabilize the bank on both sides. Access will be obtained via
an existing sanitary sewer easement.
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.
Disturbance to the buffer will be minimally necessary to access the repair site. Once work is complete,
disturbed area will be seeded and mulched back to original conditions.
1 b.
Specifically describe measures taken to avoid or minimize the proposed impacts through construction
techniques. Silt fence and appropriate erosion control measures will be established prior to beginning work.
2. Buffer Mitigation
2a.
Will the project result in an impact within a protected riparian buffer that
requires buffer mitigation?
❑ Yes ® No
2b.
If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation and
calculate the amount of mitigation required in the table below.

City of Raleigh Public Utilities Sewer Maintenance staff discovered an area of streambank failure near
6308 Winthrop Drive (Lat. 35.8674, Long. -78.6912) along Reedy Branch, a tributary of Hare Snipe Creek.
The repair area is located within a maintained sanitary sewer easement. Access to the repair location
will be in the easement on either side of the stream with no stream crossing necessary.
The following activities are proposed at this location:
• Erosion control measures and a dry work area will be established prior to work beginning.
• Approximately 40 linear feet of bank will be stabilized with rock/geotextile.
• All disturbed areas will be seeded and mulched upon completion of the work.
