Approved Units Plan Location or Reference
Stream 1,425 feet Tib to Little Creek
2. Erosion & Sediment Control Practices
Erosion and sediment control practices must be in full compliance with all
specifications governing the proper design, installation and operation and
maintenance of such Best Management Practices in order to protect surface
waters standards:
a. The erosion and sediment control measures for the project must be
designed, installed, operated, and maintained in accordance with the most
recent version of the North Carolina Sediment and Erosion Control Planning
and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and
erosion control measures must be such that they equal, or exceed, the
requirements specified in the most recent version of the North Carolina
Sediment and Erosion Control Manual. The devices shall be maintained on
all construction sites, borrow sites, and waste pile (spoil) projects, including
contractor-owned or leased borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measures must be
designed, installed, operated, and maintained in accordance with the most
recent version of the North Carolina Surface Mining Manual.
d. The reclamation measures and implementation must comply with the
reclamation in accordance with the requirements of the Sedimentation
Pollution Control Act.
3. No Waste, Spoil, Solids, or Fill of Any Kind
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian
areas beyond the footprint of the impacts depicted in the Pre-Construction
Notification. All construction activities, including the design, installation, operation,
and maintenance of sediment and erosion control Best Management Practices,
shall be performed so that no violations of state water quality standards, statutes,
or rules occur.

4. No Sediment & Erosion Control Measures w/n Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters
to the maximum extent practicable. If placement of sediment and erosion control
devices in wetlands and waters is unavoidable, they shall be removed and the
natural grade restored within six months of the date that the Division of Land
Resources has released the project.
5. Certificate of Completion
Upon completion of all work approved within the 401 Water Quality Certification
or applicable Buffer Rules, and any subsequent modifications, the applicant is
required to return the attached certificate of completion to the 401/Wetlands Unit,
North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC,
27699-1650.
6. Construction in this creek and disturbance within a 25-foot trout buffer should be
avoided during the October 15 to April 15 trout spawning period to avoid adverse
effects of sediment on eggs and larvae. However, Wildlife Resources Commission
will not object to construction of Natural Resources Conservation Service "urgent
and compelling" sites during the spawning period provided these projects are, to the
extent appropriate and practical, constructed by: (1) using flow diversion structures
such as sand bags, (2) placing large-sized rock toes and filter cloth backing for
stabilization sites before backfilling, and (3) excavating new channel alignments in
dry areas. Construction at the other non-"urgent and compelling" sites should not
occur during the spawning period to minimize the potential adverse effects of
multiple construction activities on trout resources in this creek.
7. Sediment and erosion control measures must be implemented prior to construction
and maintained on the sites to minimize sediment in downstream areas. Seeding for
a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous
cover should occur on all bare soil within five (5) days of ground disturbing activities
to provide long-term erosion control. The projects should be accomplished in stages
instead of leaving large tracts exposed to further storm events. Erosion control
matting should be used in conjunction with appropriate seeding on disturbed soils in
steep slope and riparian areas. Matting should be secured in place with staples,
stakes, or, wherever possible, live stakes of native trees. Straw mulch and tall
fescue should not be used in riparian areas. In addition, because of an anticipated
difficulty in establishing ground cover during the winter, reseeding should be
conducted, as necessary, in the spring-time with a native annual and perennial seed
mix with a temporary nursery crop of wheat, millet or other grain.
Yancey County:

September 30, 2005
8. Only clean, large, angular rock, large woody material, or other natural stream design
materials and techniques should be used for bank stabilization. Rock should not be
placed in the stream channel in a manner that constricts stream flow or that will
impede aquatic life movements during low flow conditions. Filter cloth should be
placed behind large rock that is used for bank stabilization. Properly designed rock
vanes should be constructed wherever appropriate on bank stabilization and
channel realignment stream reaches to improve channel stability and to improve
aquatic habitat. Root wads should be installed low enough in the bank so that a
significant portion (at least one-third) the root wad is inundated during normal flows.
9. The channel should be restored to a more stable condition. However, under no
circumstances should river rock, sand or other materials be dredged from the
stream channel under authorization of this permit except, if necessary, in the
immediate vicinity of the eroding banks for the explicit purpose of anchoring
stabilizing or flow/grade control structures or for reestablishing the natural and more
stable stream channel dimensions. Stream bed materials are unstable in flowing-
water situations and are unsuitable for bank stabilization. In stream dredging has
catastrophic effects on aquatic life and disturbance of the natural form of the stream
channel can cause downstream erosion problems. The natural dimension, pattern,
and profile of the stream upstream and downstream of the permitted area should not
be modified by widening the stream channel or changing its depth.
10. Stabilization measures should only be applied on or near existing erosion sites,
leaving other stable stream bank areas in a natural condition. Grading and
backfilling should be minimized and tree and shrub growth should be retained where
possible to ensure long term availability of stream bank cover for aquatic life and
wildlife. Backfill materials should be obtained from upland sites except in cases
where excess stream bed materials are available. Berms should not be permitted
because they block the floodplain, constrict and accelerate flood flows, and often fail
and sometimes impede drainage during large flood events.
11. Repairs to eroded banks should be conducted in a dry work area where possible.
Sandbags or other clean diversion structures should be used where possible to
minimize excavation in flowing water. Channel realignments should be constructed
by excavating the new channel from downstream to upstream before connecting it to
the old channel.
12. Heavy equipment should be operated from the bank whenever possible. All
mechanized equipment operated near surface waters should be inspected and
maintained regularly to prevent contamination of stream waters from' fuels,
lubricants, hydraulic fluids or other toxic materials. Equipment used in stream
channel must be clean, new or low hour equipment.
13. Disturbed stream banks and a 25-foot trout buffer, or the widest width that is
practical under the site conditions, must be restored along the construction sites to
natural riparian conditions with native trees and shrubs (e.g., silky dogwood,
rhododendron, dog hobble, red maple, silky willow, tag alder, black willow,
sycamore) to provide long-term bank stability and stream shading. Note, silky
dogwood, silky willow and black willow can be planted as live stakes collected during
the dormant growing season. Cuttings should be randomly planted on four (4) foot
centers from the waters edge to the top of the bank. Trees should be planted Ion ten
(10) to twelve (12) foot centers. Stream banks in these areas should also be
seeded with a native annual and perennial seed mix with a temporary nursery crop
of wheat, millet or other grain.
Yancey County:

September 30, 2005
14. If pasture along the stream is to be used for grazing, a fence must be constructed
outside of the riparian zone and the stream to prevent livestock from entering these
areas.
15. Diffuse Flow
All constructed stormwater conveyance outlets shall be directed and maintained
as diffuse flow at non-erosive velocities through the protected riparian zones
such that it will not re-concentrate before discharging into a stream. If this is not
possible, it may be necessary to provide stormwater facilities that are considered
to remove nitrogen. This may require additional approval from this Office.
16. Riparian Zone Replanting
Replanting of vegetation within disturbed areas located within 25 feet of the
streambank associated with any land disturbing activity, repair, replacement
and/or maintenance must be done in a manner consistant with the Guidelines
for Riparian Buffer Restoration immediately following construction. (Please
see attached.)
17. Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained
jurisdictional wetlands, waters and protective woody riparian zones in order to
assure compliance for future wetland, water and buffer impact. These
mechanisms shall be put in place prior to impacting any wetlands, waters and/or
buffers approved for impact under this Certification Approval and Authorization
Certificate. A sample deed notification can be downloaded from the
401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of
the sample deed notification may be modified as appropriate to suit to this
project.
18. Turbidity Standard
The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be
exceeded as described in 15 A NCAC 2B. .0200. Appropriate sediment and
erosion control practices must be used to meet this standard.
19. No Sediment and Erosion Control Measures in Wetlands
Sediment and erosion control measures shall not be placed in wetlands or waters
to the maximum extent practicable. If placement of sediment and erosion control
devices in wetlands and waters is unavoidable, they shall be removed and the
natural grade restored within six months of the date that the Division of Land
Resources or locally delegated program has released the project.

Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:
Land use in the vicinity o fthe proposed project site consists of agricultural and residential
uses. Damages included streambank erosion. Portions of Copperhead ('reek are flowing in
the middle of Copperhead Road, a private gravel road Portions of Lillle Creek strearnbanks
have been severely impacted by flooding.
9. Describe the overall project in detail, including the type of equipment to be used:
This Pre-Construction Nolificalion.forrn addresses DSR 57. DSR 57 covers damage on Little
Creek and its tributaries from the confluence of'Little Creek and Cane River to the upstream
extent.
Streambank erosion at nine discreet locations occurred as a result of flooding. The locations of'
these sites are shown on Figures I and 2. The post flood condition threatens the stability and
safety ofproperty, driveways, roads and associated structures.
The nine locations are not contiguous. Less than 0.8-acre per site will be disturbed during
streambank stabilization and planting activities. Therefore an Erosion and Sediment Control
Plan will not be necessary for this site. However, more than 100 feet of trout buffer will be
disturbed,for some areas during bank stabilization activities. Therefore a Trout Waiver will be
necessary for this DSR.
All work will be per f rrmed as per conversations between Allamont Environmental, US Army
Corps of Engineers, NC Wildlife Resources Commission, and on-site consultation with the US
Fish and Wildlife Service personnel on other EWP sites in this watershed. Work will include
streambank stabilization in the areas described below as well as localized removal of organic
and mineral debris and streambank re-vegetation.
Copperhead Creek is not listed in the NC DENR stream classification database. Copperhead
Creek is a tributary to Little Creek, which is classified as `C', and "t'rout' waters.
The following activities are proposed in the project area:
1) Nine distinct areas in need of streambank stabilization have been identified, totaling
approximately 1, 425 linear feet. Repairs in these areas will involve some or all of the
following:
Stabilize the riverbanks by removing unstable vegetation, placing large angular rock at
the toe of*the slope to an elevation above the normal water level, backfrlling behind and
above the stone with rocky debris removed from the floodplain or imported to the site,
topping with soil and coin matting and planting native vegetation. Additionally, in-
stream structures will be used to deflect flow from the stream bank where appropriate.
Re-establish roadside ditch for approximately 400 feet where it is flowing down the
middle of'Copperhead Road (Area 2).
2) Removal of organic, mineral, and non-native material from areas where the hydraulic
capacity of the stream channel has been reduced based upon evaluation of existing cross-
sections and regional curves.
3) Soflenin? of minor over-steepened banks and riparian plar?tin?r.
Equipment used to accomplish the above tasks includes: rubber tired skidders, 15 ton dump
truck, hydraulic track mounted excavator with thumb, and chainsaws.
The location of the streambank repair areas is provided in Figures I and 2. Represenialive
typical photographs of damage for the streambank stabilization areas are included as Figures 3
-10. Repair for each of these areas are detailed in Figures 3A- IOA.
Streantbank Stabilization
Streambank stabilization is needed on approximately 1,425 linear feet of banks within this
project area.
A key in trench will be excavated at the base of the eroded streambanks. Large (two to three
foot diameter) angular rock will be used to stabilize the toe of the bank. The area behind the
boulders will be backfrlled with rocky debris material excavated from the floodplain or
imported material, and soil will be placed on the top of the reconstructed bank to aid in the
establishment of vegetation. At Area 2, excessive rocky debris has aggraded in the roadside
channel forcing flow into the road (See Figure 4). Excessive rocky debris within the channel
will be removed using an excavator to restore the pre-flood hydraulic capacity of the channel.
In no case shall the removed material be placed (it an elevation higher than the existing
streambanks.
The repaired areas will he stabilized with a biodegradable coin matting and will be seeded with
grasses upon completion of heavy equipment work. With the landowner's permission, live
stakes and bare root stock native trees and shrubs will be planted on top of the bank
stabilization work.
Stabilizalion of streambanks and construction of structures will require placement of material
in wet conditions. In such cases, sand bags, or the equivalent, will be used to deflect water flow
away.from the work area, as well as prevent water from accumulating in the work area.
Standard erosion and sedimentation control measures will be utilized throughout the project.
The work addressed in this application is intended to improve the post flood hydraulic capacity
of the stream reaches discussed, stabilize severely eroded streambanks that are threatening
structures, and to return the areas to pre-flood conditions. The proposed actions are not
intended to enhance existing conditions or restore the stream reaches using natural channel
design techniques. Such activities would require detailed engineering evaluation and design,
which are beyond the intent of the EWP program.
A summary of affected property owners is included as Table I.
Al each work site, work shall proceed fi-om downstream to upstream. to reduce sediment
loading. All staging careers will be less than half an acre in size. Work will proceed cis follows
at each work area (as applicahle):
1. l'Yaltr the work limits.
2. Mark live trees and shrubs to be protected.
3. Construct temporary construction entrancelexits, where necessary.
4. Install sediment fence around staging areas.
5. At the end of each workday install erosion control matting or geotextile,fabric on exposed
soil using removable stakes. Erosion control mats will be constructed of coin filler or a coir
fiber mixture for maximum erosion protection, vegetation establishment assistance, and for
minimal impact on wildlife.
6. During construction, place large boulders at the toe of'repaired streambanks where
necessary.
7. Fill and compact behind boulders. Cover with soil, install erosion control mat, and seed.
8. Inspect and maintain repairs.
A site-specific engineering design based on a specific storm event was not completed because
the EWP program is not intended to fund stream restoration design or construction work.
Rather, the EWP program is designed to quickly stabilize eroding stream banks to prevent on-
going erosion, sedimentation and passible loss of property or life. Because natural channel
design methods are beyond the scope of the EWP program, published literature values were
consulted in order to specify the bank stabilization and erosion control materials and methods
described in this document. For example, we have specified that filter cloth will be placed
behind large rock used.for streambank stabilization or.for in-stream structures to increase the
stability of the repair measures and minimize sediment loading to the stream. Clean, large,
angular rock, large woody material, coir logs and natural fiber erosion control mats will be
used.for streambank stabilization.
Once site construction has ceased, the banks of the restored channel will be seeded with a
native. loodplain seed mix and the high stress areas will be lined with erosion control (EC)
matting to ensure bank stability. Furthermore, sod matting will be grubbed on-site and used
(when available) to line the near bank regions gf'the constructed/stabilized channel to provide
immediate stability. Live stakes and matting staples will be used to secure the EC fabric/sod-
matting in these high stress areas. Broadcast seeding rates will be as specified from the local
nursery, generally I5-20 lbs/acre depending on species. With landowner permission, native
shrub and tree species will be planted throughout the project reach at a rate of'320 stems/acre,
securing near bank areas and providing future shading to the channel. Existing woody
vegetation will be preserved to minimize project impacts. The following steps will be observed
with respect to vegetation:
1. Exposed soil will be covered with erosion control matting at the end of every workday.
Mats will be secured using removable stakes.
2. The project riparian zone and/or buffer areas will be re-vegetated with a combination of
native trees, shrubs and herbs/,rasses. All disturbed areas will be seeded with a temporary
native grass mixture immediately . fnlloii iiag completion of the work in those areas. T a//
fescue wi/l not be used in riparian areas.

V.
VI.
3. When possible sod will be taken from adjacent areas (ivith landowner permission) and
placed on exposed soil to provide immediate stabilization within five days of ground
disturbing activities.
4. f'sod is not available on-site temporary seeding will occur on all bare soil within five days
of ground disturbing activities to provide long-term erosion control. If sod is used, the bare
area left after^ removal of sod will be planted.
5. Re-seeding will be conducted, as necessary, with a native annual and perennial seed mix
with a temporary nursery crop of wheat, millet, or other grain.
6. Woody vegetation will be planted during the normal growing season assuming landowner
permission.
10. Explain the purpose of the proposed work:
The work being described is recovery work under the Emergency Watershed Protection program
to protect existing property and structures. Streambank stabilization will also prevent.further
erosion and sedimentation to the Cane River.

Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
On behalf of'Yancey County, Altamont will provide contractors engaged in the implementation of
this work both written and verbal instructions of all impact avoidance statements provided below.
All heavy equipment will be kept out gf'the stream channel during streambank stabilization and
stream relocation work, except where absolutely necessary to install bank stabilization measures.
Disturbance of'channel bottom and banks and equipment access areas shall be held to the
minimum necessary to allow for bank stabilization and debris removal sufficient to restore the
hydraulic capacity gfthe stream channel. Temporary grass cover shall be planted on all bare soil
within S days ofground disturbing activities. Provided landowners give permission, herbaceous
and woody shrub and tree vegetation will also be installed on the riverbank upon completion of
bank stabilization work. Yancey County will provide a site manager to routinely inspect and
supervise contractor work to help ensure impact avoidance instructions are being.followed.

VIII. Mitigation
DWQ - In accordance with 15A NCAC 211 .0500, mitigation may be required by the NC
Division of Water Quality Cor projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE -1n accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
N/A
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919) 733-5208 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.ne.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:

Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:
Land use in the vicinity of the proposed project site consists of agricultural and residential
uses. Damages included sireanihank erosion. Portions of Copperhead Creek are flowing in
the middle of Copperhead Road, a private gravel road Portions of Little Creek streamhanks
have been severely impacted by.looding.
9. Describe the overall project in detail, including the type of equipment to be used:
T his Pre-Construction Nolificalion form addresses DSR 57. DSR 57 covers damage on Little
Creek and its tribularies.fr•om the confluence of Little Creek and Cane River to the upstream
extent.
Streambank erosion at nine discreet locations occurred as a result of flooding. The locations of
these sites are shown on Figures 1 and 2. The post-flood condition threatens the stability and
safety gfproperly, driveways, roads and associated structures.
The nine locations are not contiguous. Less than 0.8-acre per site will be disturbed during
Streambank stabilization and planting activities. Therefore an Erosion and Sediment Control
Plan will not be necessary.for this site. However, more than 100 feet of trout buffer will be
disturbed for some areas during bank stabilization activities. Therefore a Trout Waiver will be
necessary for this DSR.
All work will be per./brined as per conversations between Allamont Environmental, US Army
Corps of Engineers, NC Wildlife Resources Commission, and on-site consultation with the US
Fish and Wildlife Service personnel on other EWP sites in this watershed. Work will include
Streambank stabilization in the areas described below as well as localized removal of organic
and mineral debris and streambank re-vegetation.
Copperhead Creek is not listed in the NC DENR stream classification database. Copperhead
Creek is a tributary to Little Creek, which is classified as `C', and `Trout' waters.
The following activities are proposed in the project area:
1) Nine distinct areas in need of streambank stabilization have been identified, totaling
approximately 1,425 linear feet. Repairs in these areas will involve some or all of the
following:
Stabilize the riverbanks by removing unstable vegetation, placing large angular rock at
the toe of the slope to an elevation above the normal water level, backfilling behind and
above the stone with rocky debris removed from the floodplain or imported to the site,
topping with soil and coin matting and planting native vegetation. Additionally, in-
stream structures will be used to deflect flow from the stream bank where appropriate.
Re-establish roadside ditch.for approximately 400 feet where it is flowing down the
middle of Copperhead Road (Area 2).
2) Removal of organic, mineral, and non-native material from areas where the hydraulic
capacity of'the stream channel has been reduced based upon evaluation of existing cross-
sections and regional curves.
3) Softenin(, of minor over-steepened hanks and riparian planting.
Equipment used to accomplish the above tasks includes: rubber tired skidders, l5 ton dump
truck, hydraulic track mounted excavator with thumb, and chainsaws.
The location of the streambank repair areas is provided in Figures I and 2. Representative
typical photographs of damage for the streambank slahilization areas are included as Figures 3
-10. Repair for each of these areas are detailed in Figures 3A- 10A.
Streantbank Stabilization
Streambank stabilization is needed on approximately 1,425 linear feet of hanks within this
project area.
A key in trench will be excavated at the base of the eroded streambanks. Large (two to three
foot diameter) angular rock will be used to stabilize the toe of the bank. The area behind the
boulders will be backf lled with rocky debris material excavated from the floodplain or
imported material, and soil will be placed on the top of the reconstructed bank to aid in the
establishment of vegetation. At Area 2, excessive rocky debris has aggraded in the roadside
channel forcing flow into the road (See Figure 4). Excessive rocky debris within the channel
will be removed using an excavator to restore the pre flood hydraulic capacity of the channel.
In no case shall the removed material be placed at an elevation higher than the existing
streambanks.
The repaired areas will be stabilized with a biodegradable coin mulling and will be seeded with
grasses upon completion of heavy equipment work. With the landowner's permission, live
stakes and bare root stock native trees and shrubs will be planted on top of the bank
stabilization work.
Stabilization of streambanks and construction of structures will require placement of material
in wet conditions. In such cases, sand bags, or the equivalent, will be used to deflect water flow
away from the work area, as well as prevent water from accumulating in the work area.
Standard erosion and sedimentation control measures will be utilized throughout the project.
The work addressed in this application is intended to improve the post flood hydraulic capacity
of the stream reaches discussed, stabilize severely eroded streambanks that are threatening
structures, and to return the areas to pre flood conditions. The proposed actions are not
intended to enhance existing conditions or restore the stream reaches using natural channel
design techniques. Such activities would require detailed engineering evaluation and design,
which are beyond the intent of the EWP program.
A summary of affected property owners is included as Table 1.
At each ?work site, work shall proceed,l°orn downsircum to upsdream to reduce sediment
loading. All staging areas will be less than half a?? arrc ire size. Work vi?ill proceed as follows
at each work area (as applicable):
1. Flag the work limits.
2. Mark live trees and shrubs to be protected.
3. Construct temporary construction entrance exits, where necessary.
4. Install sediment fence around staging areas.
5. At the end of each ivorkday install erosion control matting or geotexiile fabric on exposed
soil using removable stakes. Erosion control mats will be constructed of coir fiber or a coir°
.fiber mixture for maximum erosion protection, vegetation establishment assistance, and for
minimal impact on wildlife.
6. During construction, place large boulders at the toe of repaired streambanks where
necessary.
7. Fill and compact behind boulders. Cover with soil, install erosion control mat, and seed.
8. Inspect and maintain repairs.
A site-specific engineering design based on a specific storm event was not completed because
the EWP program is not intended to.fund stream restoration design or construction work.
Rather, the EWP program is designed to quickly stabilize eroding stream banks to prevent on-
going erosion, sedimentation and possible loss of property or life. Because natural channel
design methods are beyond the scope of the EWP program, published literature values were
consulted in order to specify the bank stabilization and erosion control materials and methods
described in this document. For example, we have specified that filter cloth will be placed
behind large rock used, for streambank stabilization or for in-stream structures to increase the
stability of the repair measures and minimize sediment loading to the stream. Clean, large,
angular rock, large woody material, coir logs and natural fiber erosion control mats will be
used for streambank stabilization.
Once site construction has ceased, the banks of the restored channel will be seeded with a
native floodplain seed mix and the high stress areas will be lined with erosion control (EC)
matting to ensure bank stability. Furthermore, sod matting will be grubbed on-site and used
(when available) to line the near bank regions of the constructed/stabilized channel to provide
immediate stability. Live stakes and matting staples will be used to secure the EC fabric/sod-
matting in these high stress areas. Broadcast seeding rates will be as specified from the local
nursery, generally I5-20 lbs/acre depending on species. With landowner permission, native
shrub and tree species will be planted throughout the project reach at a rate of 320 stems/acre,
securing near bank areas and providing future shading to the channel. Existing woody
vegetation will be preserved to minimize project impacts. The following steps will be observed
with respect to vegetation:
1. Exposed soil will be covered with erosion control matting at the end oj' every workday.
Mats will be secured using removable stakes.
2. The project riparian zone and/or buffer areas will be re-vegelated with a cornhinulion of
native trees, shrubs and herhs/grasses. All disturbed areas will be seeded with a temporary
native grass mixture immedialely follol-ving completion of the work in those areas. Tall
fescue will not he used in riparian areas.
3. When possible sod will he taken from adfacent areas (with landowner permission) and
placed on exposed soil to provide immediate stabilization within five days of ground
disturbing activities.
4. If sod is not available on-site temporary seeding will occur on all hare soil within five days
of ground disturbing activities to provide long-term erosion control. If sod is used, the bare
area left after removal of'sod will be planted
5. Re-seeding will be conducted, cis necessary, with a native annual and perennial seed mix
with a temporary nursery crop of wheat; millet, or other grain.
6. Woody vegetation will be planted during the normal growing season assuming landowner
permission.
10. Explain the purpose of the proposed work:
The work being described is recovery work under the Emergency Watershed Protection program
to protect existing property and structures. Streambank stabilization will also prevent,further
erosion and sedimentation to the Cane River.
