Subject: City of Fayetteville - East Park Drive Streambank Stabilization
UT to Branson Creek [030615, 18-27-5-1, C]
Dear Ms. Karoly:
Thank you for your prompt review of the subject project submission. The
following information is offered in response to your request for additional
information dated June 12, 2009:
1. Please explain why both sides of the stream require stabilization
Both sides of the stream require stabilization to ensure that during large
storm events an unbalanced flow is not created. An unbalanced flow could lead
to un-natural erosion on the opposite bank and/or a change in the natural
direction of the stream bed. Stabilizing both sides during this project will prevent
additional disturbance in the future. Although not readily visible in the photos,
field observation has indicated some erosion on the bank opposite from the
failure. In general, the City designs all outfalls and associated stabilization
devices symmetrically to minimize the effect of water being concentrated as it is
leaving a pipe during storm events generating unusually high water volumes and
velocities.
2. The total impacts to the streams on the stream table (50 linear feet) does not
match the total for the column (20 linear feet) Please address this discrepancy
The quantity of 50 linear feet was a typographical error. The correct
impact length is 20 feet. A corrected PCN form is enclosed. The US Army Corps
of Engineers will also be provided with a corrected copy.

3. Reno mattress should not be placed below the ordinary high water mark vet
your plans show it going across the stream. Please explain why this is
necessary.
The Reno Mattress has been placed at the same elevation as the outfall
and existing stream bed per the suggestion of the US Army Corps of Engineers
during the design of similar project. The City understands that the intent of the
USACE was to ensure that aquatic life can pass up and down stream with
minimal disruption. Previous experience with Reno Mattress devices indicates
that after installation, the void space in the mattress fills with sediment and acts
in the same fashion as the natural streambed. During periods of heavy flow, the
sediment erodes but the Reno Mattress remains in place, protecting the outfall
from being undercut by erosion.
Should you have any further questions about the project or need additional
information, please feel free to contact me by telephone at [phone] or by
email at 0larch (a)-ci.fay. nc.us. Thank you for your continued assistance.
Respectfully,
Jo

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
