Please give a brief project description below.

This PCN is being submitted after the fact for emergency bank
stabilization work (NWP-3). This is an emergency bank stabilization
project along the French Broad River in Marshall, NC just
downstream of the Capitola Dam on river right looking downstream.
We had a field meeting with Andrew Moore (NCDEQ) in Marshall
Friday February 5, 2021. We also had a conference call with
Brandee Boggs (USACE), and Andrea Leslie (NCWC) on February
10th, and a field meeting with same Friday February 12, 2021.
Due to a failure in a few riser boards on the Capitola Dam, high
velocity water that was directed at a concrete river bank wall resulted
in a bank failure. This bank failure was compromising Norfolk
Southern's rail line. French Broad Electric Cooperative temporarily
lowered additional riser boards to relieve water pressure and
velocities to the bank failure. Norfolk Southern installed large
boulders where the concrete bank wall had fallen into the river to
prevent further loss of soil materials adjacent to the railroad.
Temporary sheet piles were driven approximately 10-15 feet into the
ground about 3 feet from the rail road tracks to further stabilize the
tracks. Additional stabilization work being conducted at the bank
failure includes the falling:
• Partially excavate the existing fill and remove spoils behind the
existing concrete wall while releasing as little into
the waterway as necessary to satisfy the USACE.
• Strategically remove and/or push over sections of the existing
concrete wall that have already failed and backfill
with additional rip rap.
• Timeline Constraint: French Broad River Coop (FBRC) has helped
NS complete the work by keeping metal riser
plates in a lowered position temporarily. This shifts the concentrated
flow of the river out away from the bank.
FBRC needs to return their risers upright to limit the long-term
impacts to their power generation capability. NS is
seeking to complete all emergency stabilization work as quickly as
possible.
• Rock will be placed using rail car air dumps, front end loader and
excavator.
• Affected section will be roughly 100 cubic yards of fill over a section
of roughly 10OLF along the existing wall at
three general locations. The cross sectional area affected will be a
1:1 sloped section measured roughly 8' back
and 8' deep from the existing concrete wall — some of this fill has
already been removed. These locations are:
o Up to 25' on downstream side of the fill section that has failed
where rip rap has already been placed, and up
to 75' upstream of same location.
o Section further up between existing failure filled with rip rap and
where the dam meets the existing concrete
wal I
• All excavated fill material wi11 be temporarily stockpiled in an upland
staging area owned by Norfolk Southern just
south of the project site. Appropriate sediment controls including
sediment fencing wi11 be installed around fill
material. Fill material will be ultimately moved to a permanent upland
fill area and stabilized.
Please give a couple of dates you are available for a meeting.
