Attached is the Project Narrative with the addendum. Was there anything else needed to proceed with this Major Permit to proceed in
getting approved?

Thanks!

PROJECT NARRATIVE
NEUSE RIVER DRIVE PROJECT
Jack & Stacey King – Richard & Gloria Gustafson
3004 & 3006 Neuse River Drive

Proposed Project: Terraced vinyl bulkheads over both properties to preserve their
waterfront from further erosion. The bottom bulkhead will be 160’x10’ on the
Gustafson property and continue onto the King property at 130’x10’. There will be a
50’ Vinyl wingback on the King property where it attaches to the wood terraced wall
built in 2002. The upper terraced wall will also be vinyl. The lengths are 160’x6’ on
Gustafson’s property and 150’x6’ on the King’s property. All existing mature trees
will stay if possible.

Purpose of Project: Both of these properties have suffered significant erosion the
during the last 12-15 years. The 22’ cliff has become dangerous. Both parties don’t
know how much longer it can survive another hurricane season. The waterfront
needs stabilization and protection.

Construction Method of 10’ Vinyl Bulkhead: The manufacturer of the vinyl sheet
piles will be ESP (Everlast Synthetic Products). We are going to use their 3.5 Series –
20’ sheets (see attachment for specifications). Top and bottom whaler will be 6x6
thru bolted to a back 4x6 – these will be located 4’ from the bottom and 3’ from the
top. The lower tie backs will be ¾”x16’ every 5’ O.C. to 3’ deadmen and the upper tie
backs will be 5/8”x20’ every 5’ O.C. to 3’ deadmen. The wood cap will be double 4x4
thru bolted to a 2x10 and fastened with S.S. screws. All bulkhead hardware will be
galvanized. There will be a rock bed drain installed for storm water run off. This
drain will be placed directly behind the wall and consist of 3’ wide x 2’ deep of
gravel covered with filter cloth. Blue Marlin Filters (see attachment for
specifications) will be placed every 20’ along wall for the storm water to run
through the wall. This prevents hydrostatic pressure build up. The bulkhead will be
backfilled with clean, non-clay sand. See Sedimentation Control Plan for root
stabilization.

Construction of 6’ Vinyl Bulkhead: The manufacturer of the vinyl sheet piles will
be ESP (Everlast Synthetic Products). We are going to use their 3.1 Series – 12’
sheets (see attachment for specifications). Bottom whaler will be 6x6 thru bolted to
a 4x6 and top whaler will be 4x4 on the front thru bolted to 4x4 on the back. Tie
back system will consist of 5/8”x16’ every 7’-6” O.C. to 3’ deadmen. The wood cap
will be double 4x4 thru bolted to a 2x10 and fastened with S.S. screws. All bulkhead
hardware will be galvanized. There will be a rock bed drain installed for storm
water run off. This drain will be placed directly behind the wall and consist of 3’

wide x 2’ deep of gravel covered with filter cloth. Blue Marlin Filters (see attachment
for specifications) will be placed every 20’ along wall for storm water to run through
the wall. This prevents hydrostatic pressure build up. The bulkhead will be
backfilled with clean, non-clay sand. See Sedimentation Control Plan for root
stabilization.

**ADDENDUM: PURPOSE OF UPPER 6’ VINYL BULKHEAD – the structural
purpose of this bulkhead is to distribute load from rainwater between the top and
bottom bulkheads. The water that is captured by the upper bulkhead – inside its
rock drain system -- will be diverted into another rock drain system down to the
lower wall. Thus alleviating the hydrostatic pressure behind the large 10’ vinyl
bulkhead. (This addendum was per the meeting on 12/20/16 with Mr. Anthony
Scarbraugh & Jason Hill.)

Proposed Method of Work: Due to the nature of this project, the height and
instability of this cliff and the number of trees blocking the work zone area there
will need to be a temporary access road/ledge constructed in order to install the
proposed structures. Our plan is to start at the existing retaining walls on King’s
property, a sloped road will be cut into the hillside down to the NWL. There will be
sand-filled bags placed at the beginning of sloped road to deflect rain water away
from road, this will hopefully prevent any washing away of the roadway. Three sets
of silt fence will be placed down the sloped roadway as well. Along the NWL,
existing rock will be removed and placed in a line along waterfront on King’s
property (18’ out on average), silt fence and filter cloth will be backed up against the
rock and sand will be added for a temporary roadway/access to construction
bottom wall. Basically this roadway/access allows approx. 2’ area to work from to
build the bottom bulkhead. As the bottom bulkhead is being constructed, the plan is
to pull down some of the cliff, and slope/sculpt the hillside. There are many fallen
trees along this cliff area. If rock is unavailable along the roadway construction,
some of the fallen trees may be used to construct the temporary roadway. All fallen
trees will be removed or covered in backfill at the end of the project. The
roadway/access will be removed at the end of project or at the end of the lower
bulkhead being built. Once the hillside is sloped/sculpted and the two new walls are
built, then clean backfill will be brought in and distributed.

Proposal to extend construction water ward 20’: Due to the current, existing
condition of the waterfront, there is no safe area to place the equipment to start
sloping and sculpting the hillside. As it is right now, it’s an approximate 22’ vertical,
and slightly unstable cliff. Once the access road is made to get to the bottom of the
cliff, the equipment will be placed in the water to start moving the earth and shaping
the slope for the placement of the bottom wall. The normal water depth in this area
is approximately 1’-2’, so my barge is unable to access the area, as it needs 2’+ of
water. So this option is not possible either. As it stands right now, this is the only
option my company has to install this bottom 10’ bulkhead and to slope/sculpt the
hillside safely.

Erosion & Sedimentation Control Plan: All existing mature trees will remain on
both properties if possible and their root system will not be bothered as much as
construction allows. Once all backfill is distributed and graded, 3 sections/rows of
silt fence will be installed at the top retaining wall and 5 sections/rows of silt fence
will be installed between the 2 walls. And once section/row will be installed up next
to bottom wall. There will be grass seed distributed thoroughly and hay for
protection. If needed along the edge of each of the walls, a 2’ section of sod will be
planted for quicker root system. All seeded areas will be fertilized and reseeded as
necessary until dense, vigorous grass/vegetation covers the work zone area.
Depending on the time of year this project is completed will depend on the type of
grass seed used. See the attachment for the type of grass needed for the time of year.
