Project Description
3a
Describe the existing conditions on the site and the general land usehn the vicinity of the project at the time,of this
application
The Project Site is located at 223 Ryans Place, off of,Dewitt Barnett Road and near historic Valle Crucis The Project Site
encompasses approximate 230 If of streambank along the northern side (right bank) of the Watauga River, on two
adjoining properties, both of which are owned by Tommy'Lawrence The upstream property has &,residence - located
within fourteen feet of the streambank and the second ,property is undeveloped pasture land Severe bank erosion has
occurred and continues along the entire4he entire 230 feet of the site bordenng,the Watauga River
The entire project site is located within the Regulatory - Floodway, there are no jurisdictional wetlands on the site and the
Watauga River is the only jurisdictional Water of the US ,on the site; forming the isouthem property boundary. Across, the
river to the,south is a largetihay field There is a single,famdy residence on'the adjacent lot to the east, ,followed by several
more similar houses on lots bordering the river further east The area to the north of the site is hay field/pasture for
several hundred feet and more houses, further north, on the far side of the valley To the west is a hay field
An analysis of aerial photographs from 2007 and 2014 was used to estimate the amount ofmver bank that has been lost
to erosion Based, on this analysis, the lower (downstream) 135 linear feet of the site has lost at least 5 to 7 feet of flat
ground at the top of the bank Existing river banks are actively eroding, vertical or undercut with almost no riparian
vegetation,'banks are 10 to 12 feet'high in this area
The upper portion of river bank 'is less eroded, still has several trees and an intact, but stressed and eroding, bankfull
bench The edge of the bankfull bench is actively eroding, with one large tree in imminent danger of falling into the river
General land use, in the vicinity of project is agricultural and lowAensity single family residential

3e
Descnbe the overall project in detail, includinathe type,of eguigment,to be used -
The project will involve the stabilization and reconstruction of the severely eroded river bank for approximately 135 linear
feet and the stabilization�of moderately eroded bank for- approximately`95 linearfeet
Lower 135 -foot Section Reconstructed bank sections will involve the placement of large boulders to stabilize the toe of
the river bank up to the approximate bankfull elevation Boulders Will be installed about 2 -feet below stream bed if
possible to prevent undercutting This section of river bed is dominated by bedrock that may prevent trenching to install
the boulders below stream bed but the bedrock (if present) will protect the boulders from 'being undercut Above the
boulders, the bank,wdl be stabilized using bioengineering techniques'includmg reinforced brush layering (see details) to a
height of roughly 5 feet above the boulders Above the reinforced sod, compacted topsoil will be added to tie into existing
yard
Upper 95 -foot Section Stabilized bank sections will involve the placement of large boulders to armor the toe of the river
bank up to the approximate bankfull elevation, Boulders will be installed about'2 -feet below stream bed if possible to
prevent undercutting Above the�boulders, the existing bank will be minimally graded to tie to the boulders
Temporary stream impacts will occur during bank stabilization work associated with access to the upper 95 -foot section
and installation of the boulder toe stabilization Temporary impacts will include installation of a non - erodible berm to keep
flow,away from work area Additionally, equipment will need to operate in the river to construct the upper 95 -foot section,
this,is necessary to avoid damaging remaining trees and because the house is so close to the,top of bank in this area, it
would be unsafe to attempt operate equipment in that area All temporary impacts will be minimal and site conditions will
be restored to an improved state at,the, completion of,the project
Following grading work, coin mat 40 or equivalent will be installed along lower bank sections Disturbed' areas will be
seeded with a temporary erosion control seed mix and over seeded with native riparian seed mix (ERNST -304) from
Ernst Conservation Seeds or similar. Please refer to attached Streambank Stabilization Plan Sheet, Cross Section Views,
and Photo Sheet for details, and notes
A track excavator, skid -steer loader, and dump truck will be used for the streambank stabilization work

D. Impact Justification and Mitigation
1. Avoidance,and Minimization
1a Specifically describe measures taken to =avoid or minimize the proposed'impacts in designing project.
This project will involve both temporary and permanent impacts but all impacts will be minimal The outcome of'the
`project1wdl be to improve overall water quality by addressing the erosion,and bank instability concerns The project has
been designed to both provide adequate bank protection to achieve the stated goals but also the reinforced brush
layering component will serve to provide increased vegetation on the banks to reduce thermal impacts, improve instream
and riparian habitat and provide wildlife cover
,b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques
Disturbed areas of the streambank will be stabilized immediately following completion of grading. Construction of'the
boulder wall will be accomplished-from the river for the upper section an order to protect existing trees on the bank, it is felt
the long term benefits of retaining these treesfar outweighs the short term impacts from construction A non - erodible will
be installed in the river to, isolate the work area and minimize sedimentation For the lower end of'the project the existing
bank will be, graded back to create,a bench from which to operate,egwpment and move materials, this will minimize
instream work in this section of the project

Photo One: View looking to the southeast at the eastern property
boundary (on the fence line) and the edge of the Upper Section of
the Lawrence Property Watauga River Bank Stabilization Project.
Four foot tall boulder wall will be used to stabilize the low bank
and will tie -in at property boundary line.
Photo Three: View looking to the southeast at area of severely
eroded streambanks in the Lower Section of the Lawrence project.
Four foot tall boulder wall and reinforced brush layering at 2:1
slope will be used to stabilize in the Lower Section.
Photo Five: View looking to the northeast at Lower Section of the
Lawrence project. Area of severely eroded streambank is visible in
photo, averaging 10-1 Tin height, most of which are near vertical
and actively eroding. Bank erosion is occurring in the direction of
the residence seen in background.
Photo Two: View looking to the southeast of the vegetated low
bank in the Upper Section of the project. Four foot tall boulder
wall to follow low bank.
Photo Four: View looking to the north at the edge of the Lower
Section of the Lawrence project near the western property
boundary.
Photo Six: View looking to the cast from the top of the
streambank in the Lower Section of the Lawrence project.
Proximity of residence to areas of severe bank erosion can be
seen in photo; closest portion of residential support members is
14' from edge oferoding bank.

Reinforced Brush Layering
Installation Guidelines
MATERIALS:
Live Cuttings: Live cuttings shall of one or more of the following species:
• Salix nigra - Black Willow
• Cornus amomum - Silky Dogwood
• Salix sericea - Silky Willow
• Physocarpus opulifolius - Nine Bark
Cuttings shall be T to 6' long, reasonably straight, free of disease, damage, defects, and
1" to Y' diameter at the base. If 'cuttings were taken form,,actively growing plants (non-
dormant) leaves shall be removed. Cuttings shall be kept wet until installation. Non-
dormant: cuttings may be stored submerged (50,- %,of length) for up to 5 days. Cuttings
with emerging roots shall not be used.
Soil Wrap: Soil wrap,shall consist of 100%, spun coir fiber netting, minimum weight -400
g/m2, approximate 10 -ft. roll width (ex. Granite Environmental Control Mat 40 or
similar). Staples shall be 11 gage, U- shaped, min. 8" long with 2" crown.
Boulders: Large angular boulders suitable for stacking, typical size 4' to 6' long, 2' to 4'
wide, 1.5' to 2.5' thick. Some smaller sizes will also be needed.
Fill Material: Fill material for soil layer shall be A- horizon topsoil free of large rock,
sticks and roots.
INSTALLATION
1. Grade back river bank to allow access to toe of slope, create a berm using non-
erodible materials to isolate the work area to prevent sedimentation of river.
2. Outer edge of boulder wall and top elevation of boulder wall will be field located
by engineer or designer.
3. Footer�rocks' for boulder wall shall be installed 2' below streambed unless bedrock
is encountered.
4. Geotextile non -woven fabric (Mirafi 1100N or similar) shall be installed between
boulder wall and soil bank, washed gravel or river gravel shall be placed behind
boulder wall to fill voids.
5. Construct boulder wall to approx. bankfull elevation, wall slope should be
roughly 0.5:1.
6. Place soil wrap over boulder wall with back edge anchored behind boulders and
front edge overhanging over boulder wall.
a. Add topsoil for first lift, fold soil wrap back over lift and staple at 2 -foot
intervals. (front face of first.reinforced soil lift should be set back from
edge of boulder wall by approx. 2 -feet to create a small bankfull bench).
b. Soil wrap and lift should be thoroughly moistened to a depth of 8- inches
to achieve desired compression. Water shall be applied in a fine spray to
avoid erosion.
c. Height of first; lift -should not exceed 1 =foot compressed additional lifts
should be approximately 1.5 -feet thick compressed.
d. The top surface of the soil lift should angle, from front to back, down at 10
deg. to 20 deg. (between 3:1 and 4:1).
7. Cuttings shall be placed in layers with approximately 45 cuttings per yard.
a. Cuttings shall be placed with minor criss - crossing with different species
mixed and evenly distributed.
b. Cuttings shall be placed with butt ends ,toward ,bank and leafy ends
towards river, butt ends must be lower than leafy ends.
c. Leafy ends shall protrude from edge of lift by no more,than 12- inches.
8. Deposit topsoil over cuttings, water liberally and compress to 2" to-4 ".
9. Repeat steps 6; 7, and 8 for 3 additional, lifts. Front face of reinforced:soil wall
shall have slope of approximately 2:1.
10. All cuttings shall be covered by a soil wrap layer by the end of each day.
11. Add topsoil in compacted layers above top lift to tie into existing yard.
12. Stabilize upper topsoil layer with light duty, biodegradable, erosion control mat.
