Stream Restoration Plan
For the Mathot Property

Brasstown Creek
Brasstown, North Carolina

Mickey B. Henson
Principal Hydrologist
Appalachian Environmental Services

May 31, 2000

PROJECT SITE
The stream restoration for the Mathot's is located on 820 feet of Brasstown Creek

in Brasstown, North Carolina (N350 1.897' W83057.438' on the WGS84 Datum). Please

see Appendix-A for a topographic site map and stream restoration site map. The project

site has a long-term history of streambank erosion. The erosion is due to the lack of low

growing vegetation, which holds the soil to the streambank.

SCOPE

The objective ofthis stream restoration project is to improve the water quality,

riparian quality and stability of this stream. Long-term stabilization will be

accomplished by stabilizing the riparian area with native vegetation, creating a bankfull

bench, and installing rock vanes to redirect the flow during storm events. Specific

objectives for the project are as follows:

1. Construct a new stream channel base upon reference reaches.

2. Construct rock vanes to redirect flow during storm events.

3. Stabilize the bankfull elevation along the reach.

4. Slope and vegetate the streambanks so they are more resistant to flooding.

5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade

the stream, and provide wildlife cover and food.

CHANNEL RESTORATION

Meander Design

The approach used results in an average channel slope being determined by

meander geometry (meander wavelength, meander arc length, average width at bankfull,

meander amplitude, radius of curvature and arc angle). These approaches are based on

Appalachian Environmental Services

Page 1

the assumption that the controlling factors in the stream channel (water and sediment

inputs, bed material gradation, and bank erosional resistance) will be similar to those in a

selected reference reach (either the restoration reach before disturbance or undisturbed

reaches). If the reach targeted for restoration is closely bounded by undisturbed

meanders, dimensions of these undisturbed reaches may be studied for use in the restored

or created reach.

Bankfull Determination

Visual identification of bankfull flow on large streams in alluvial bottoms is

relatively easy. However, small streams in the Southern Appalachians rarely have

alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic

breaks between the bank and the floodplain common in larger streams and rivers.

Therefore, bankfull flow was estimated by observing vegetation, bare rock, washed root

lines, and changes from a steep to gentle bank slope.

We have experienced that the best indicators of bankfull flow in the Southern

Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition

on point bars. Storms larger than bankfull can erode the stream banks and mask the

indicators. In the Southern Appalachians, the vegetation line is probably the most

difficult indicator to use to determine bankfull depth. Riparian vegetation in the

mountains withstands high flows and may even revegetate quickly into the bankfull area.

This is especially true with certain types of mosses. Some of the problems of

determining reliable indicators of bankfull flow stem from the stream banks being

undercut and caving in.

Appalachian Environmental Services

Particle Size Distribution (Dso)
Particle size data are usually reported in terms of Dj, where I represents some

nominal percentile of the distribution and Dj represents the particle size, usually

expressed in millimeters, at which i percent of the total sample by weight is finer. For

example, 50 percent of the total sample would be finer than the Dso particle size. For

estimating size distribution in steep mountain streams with substrate much coarser than

the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)

samplers, a pebble count, in which at least 100 bed material particles are manually

collected from the streambed and measured, is used to measure particle size. At each

sample point along the cross section, a particle is retrieved from the bed, and the

intermediate axis is measured. The measurements are tabulated as to number of particles

occurring within predetermined size intervals, and the percentage of the total number in

each interval is then determined. Again, the percentage in each interval is accumulated to

give a particle size distribution, and the particle size data are reported as described above.
Area-A

Because of continuing scouring and down cutting this channel is now a G-type

stream. To restore this portion of the stream it is recommended that a bankfull bench be

constructed. Creating a bench will slow storm event velocities and dissipate energy of

the flows that erode the streambanks. There will be three rock vanes constructed. The

rock vanes and toe protection reduce stress in the near bank region and are constructed at

locations that need bank protection. Rock vanes should be constructed from boulders that

are larger than the rocks normally moved by the stream. Rock vanes point upstream and

will increase the stage on the near bank and move flow toward mid-stream. Vanes are

Appalachian Environmental Services

Page 3

built at a 200 to 300 angles from the near bank Vanes slope from the bankfull elevation

into the bed of the stream at a 5 to lO% slope. The length of the vane is dependent on the

bankfull stage. For this reach the largest boulder needed is 6'x5'x4' (embedded 50%) and

the smallest is 3'x3'x3' (embedded 30%). Above the toe protection, the streambank will

be stabilized using bioengineering. Please review Appendix-B for existing bank sections

and Appendix-C for restored bank sections.

Area-B

This reach of the stream is highly eroded. This erosion is due to the removal of
the understory vegetation. It is recommended that the streambanks in this stretch of

Appalachian Environmental Services

Page 5

stream be sloped at a ratio of2.5 to 1 and heavily vegetated. Please review Appendix-B

for existing bank sections and Appendix-C for restored bank sections.

STREAMBANK STABILIZATION

Above the bankfull elevation the streambank will be sloped to the top of the bank

and vegetated. This feature benefits the stream by slowing water velocity during high

water events. This in turn reduces the amount of erosion occurring on the streambanks.

This process will increase cross-sectional area. Coconut blankets will be pinned into the

bank for short-term (4 years) stabilization. The blankets will stabilize the streambank

long enough for the vegetation to root and stabilize the stream for the long-term.

RIPARIAN RESTORATION

After the streambank has been sloped it will be seeded with native herbaceous and

woody plant seeds described on the following native plant list. Seeded sections of the

bank will be covered with coconut fiber blankets. These blankets will protect the area

from the streambed to the top of the streambank and be stapled to the ground using metal

landscape staples. Low growing woody species such as Henry's Garnett, Silky

Dogwood, and Buttonbush will be planted. These species will be planted as potted stock

or B&B during the next dormant season. As much as possible trees that are on site will

be avoided as the streambanks are altered. On the upper banks we will plant taller

growing trees that provide shade, stable creek banks and wildlife cover and food. The

desires of the landowner will be incorporated into the planting plans whenever possible.

The riparian restoration component of this project was broken down into a three-

zone approach. The species selected were chosen to be aesthetically pleasing and to

benefit wildlife by providing food or habitat. We are also supporters of the Southern

Appalachian Environmental Services

Page 6

Appalachian Native Plant Initiative (SANPI), so we will only be using native species to

revegetate the riparian zone. A selection of the following species will be used at this site:

Arrowhead (Sagittaria latifolia), Pickerelweed (Pontederia cordata), Cardinal Flower

(Lobelia cardinalis), Henry's Garnett (Itea virginica), Dog Hobble (Leucothoe

fonianesiana), Bushy St. Johnswort (Hypericum densiflorum), Buttonbush (Cephalanthus

occidentalis), Silky Dogwood (Comus amomum), Baldcypress (Taxodium distchum),

Black Walnut (Juglans nigra), Green Ash (Fraxinus pennsylvanica), Red Maple (Acer

rubrum), and Sycamore (Platamus occidentalis). All flower species will be planted 3 to 4

feet apart, bush species 4-8 feet apart and trees will be planted 10-15 feet apart.

PROJECT SITE

The stream restoration for the Mathot's is located on 820 feet of Brasstown Creek

in Brasstown, North Carolina (N350 1.897' W83057.438' on the WGS84 Datum). Please
see Appendix-A fora topographic site map and stream restoration site map. The project
site has a long-term history of streambank erosion. The erosion is due to the lack of low
growing vegetation, which holds the soil to the streambank.
SCOPE

The objective of this stream restoration project is to improve the water quality,

riparian quality and stability of this stream. Long-term stabilization will be

accomplished by stabilizing the riparian area with native vegetation, creating a bankfull

bench, and installing rock vanes to redirect the flow during storm events. Specific

objectives for the project are as follows:

1. Construct a new stream channel base upon reference reaches.

2. Construct rock vanes to redirect flow during storm events.

3. Stabilize the bankfull elevation along the reach.

4. Slope and vegetate the streambanks so they are more resistant to flooding.

5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade

the stream, and provide wildlife cover and food.

CHANNEL RESTORATION

Meander Design

The approach used results in an average channel slope being determined by

meander geometry (meander wavelength, meander arc length, average width at bankfull,

meander amplitude, radius of curvature and arc angle). These approaches are based on

Appalachian Environmental Services

Page 1

the assumption that the controlling factors in the stream channel (water and sediment

inputs, bed material gradation, and bank erosional resistance) will be similar to those in a

selected reference reach (either the restoration reach before disturbance or undisturbed

reaches). If the reach targeted for restoration is closely bounded by undisturbed

meanders, dimensions of these undisturbed reaches may be studied for use in the restored

or created reach.

Bankfull Determination

Visual identification of bankfull flow on large streams in alluvial bottoms is

relatively easy. However, small streams in the Southern Appalachians rarely have

alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic

breaks between the bank and the floodplain common in larger streams and rivers.

Therefore, bankfull flow was estimated by observing vegetation, bare rock, washed root

lines, and changes from a steep to gentle bank slope.

We have experienced that the best indicators. of bankfull flow in the Southern

Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition

on point bars. Storms larger than bankfull can erode the stream banks and mask the

indicators. In the Southern Appalachians, the vegetation line is probably the most

difficult indicator to use to determine bankfull depth. Riparian vegetation in the

mountains withstands high flows and may even revegetate quickly into the bankfull area.

This is especially true with certain types of mosses. Some of the problems of

determining reliable indicators of bankfull flow stem from the stream banks being

undercut and caving in.

Particle Size Distribution (Dso)
Particle size data are usually reported in terms ofDj, where I represents some

nominal percentile of the distribution and Dj represents the particle size, usually

expressed in millimeters, at which i percent of the total sample by weight is finer. For

example, 50 percent of the total sample would be finer than the Dso particle size. For

estimating size distribution in steep mountain streams with substrate much coarser than

the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)

samplers, a pebble count, in which at least 100 bed material particles are manually

collected from the streambed and measured, is used to measure particle size. At each

sample point along the cross section, a particle is retrieved from the bed, and the

intermediate axis is measured. The measurements are tabulated as to number of particles

occurring within predetermined size intervals, and the percentage of the total number in

each interval is then determined. Again, the percentage in each interval is accumulated to

give a particle size distribution, and the particle size data are reported as described above.

Area-A

Because of continuing scouring and down cutting this channel is now a G-type

stream. To restore this portion of the stream it is recommended that a bankfull bench be

constructed. Creating a bench will slow storm event velocities and dissipate energy of

the flows that erode the streambanks. There will be three rock vanes constructed. The

rock vanes and toe protection reduce stress in the near bank region and are constructed at

locations that need bank protection. Rock vanes should be constructed from boulders that

are larger than the rocks normally moved by the stream. Rock vanes point upstream and
Pwill increase the stage on the near bank and move flow toward mid-stream. Vanes are

built at a 200 to 300 angles from the near bank Vanes slope from the bankfull elevation

into the bed of the stream at a 5 to 10% slope. The length of the vane is dependent on the

bankfull stage. For this reach the largest boulder needed is 6'x5'x4' (embedded 50%) and

the smallest is 3'x3'x3' (embedded 30%). Above the toe protection, the streambank will

be stabilized using bioengineering. Please review Appendix-B for existing bank sections

and Appendix-C for restored bank sections.

This reach of the stream is highly eroded. This erosion is due to the removal of
the understory vegetation. It is recommended that the streambanks in this stretch of

stream be sloped at a ratio of2.5 to 1 and heavily vegetated. Please review Appendix-B

for existing bank sections and Appendix-C for restored bank sections.

STREAMBANK STABILIZATION

Above the bankfull elevation the streambank will be sloped to the top of the bank

and vegetated. This feature benefits the stream by slowing water velocity during high

water events. This in turn reduces the amount of erosion occurring on the streambanks.

This process will increase cross-sectional area. Coconut blankets will be pinned into the

bank for short-term (4 years) stabilization. The blankets will stabilize the streambank

long enough for the vegetation to root and stabilize the stream for the long-term.

RIPARIAN RESTORATION

After the streambank has been sloped it will be seeded with native herbaceous and

woody plant seeds described on the following native plant list. Seeded sections of the

bank will be covered with coconut fiber blankets. These blankets will protect the area

from the streambed to the top of the streambank and be stapled to the ground using metal

landscape staples. Low growing woody species such as Henry's Garnett, Silky

Dogwood, and Buttonbush will be planted. These species will be planted as potted stock

or B&B during the next dormant season. As much as possible trees that are on site will

be avoided as the streambanks are altered. On the upper banks we will plant taller

growing trees that provide shade, stable creek banks and wildlife cover and food. The

desires of the landowner will be incorporated into the planting plans whenever possible.

The riparian restoration component of this project was broken down into a three-

zone approach. The species selected were chosen to be aesthetically pleasing and to

benefit wildlife by providing food or habitat. We are also supporters of the Southern

Appalachian Environmental Services

Page 6

Appalachian Native Plant Initiative (SANPI), so we will only be using native species to

revegetate the riparian zone. A selection of the following species will be used at this site:

Arrowhead (Sagittaria latifolia), Pickerelweed (Pontederia cordata), Cardinal Flower

(Lobelia cardinalis), Henry's Garnett (!tea virginica), Dog Hobble (Leucothoe

fonianesiana), Bushy St. Johnswort (Hypericum densiflorum), Buttonbush (Cephalanthus

occidentalis), Silky Dogwood (Comus amomum), Baldcypress (Taxodium distchum),

Black Walnut (Juglans nigra), Green Ash (Fraxinus pennsylvanica), Red Maple (Acer

rubrum), and Sycamore (Platamus occidentalis). All flower species will be planted 3 to 4

feet apart, bush species 4-8 feet apart and trees will be planted 10-15 feet apart.
