Approval of 401 Water Quality Certification with Additional ConditiQf1$-WATERQ~~~Ut.,NCH
WETLANDS AND STORMW
Dear Mr. Wiseman:

You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 350 feet of streams for the purpose of
streambank stabilization and woody debris removal I trash removal at the subject
properties, as described within your application received by the N.C. Division of Water
Quality (DWQ) on July 14, 2005. After reviewing your application, we have decided that
the impacts are covered by General Water Quality Certification Number(s) 3367 (3367).
The Certification(s) allows you to use Nationwide Permit(s) 37 when issued by the US
Army Corps of Engineers (USACE). In addition, you should obtain or otherwise comply
with any other required federal, state or local permits before you go ahead with your
project including (but not limited to) Erosion and Sediment Control, Non-discharge, and
stormwater regulations, Also, this approval to proceed with your proposed impacts
or to conduct impacts to waters as depicted in your application shall expire upon
expiration of the 404 or CAMA Permit.

This approval is for the purpose that you described in your application. (Nothing in this
approval should be interpreted as giving permission to remove bedload material
from the existing channel, nor allowing for the construction of berms which
would not allow the stream access to it's floodplain.) As "stable" and "pre-storm"
are not interchangeable terms, all work must be to ensure stability, regardless of
channel location. Additionally, channels cannot be returned to it's pre-storm location
unless there is documented instability is submitted and approved as part of the
application package. If you change your project beyond the approval here, you must
notify us and you may be required to send us a new application. If the property is sold,
the new owner must be given a copy of this Certification and approval letter and is
thereby responsible for complying with all conditions. If total fills for this project (now or
in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval
requires you to follow the conditions listed in the attached certification and any
additional conditions listed below.

The Additional Conditions of the Certification are:

1. Impacts Approved

The following impacts are hereby approved as long as all of the other specific
and general conditions of this Certification (or Isolated Wetland Permit) are met.
No other impacts are approved including incidental impacts:

Amount Plan Location or Reference
Approved (Units)
Stream 350 (feet) Row Branch

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.

A very County:
Page 3 of6
July 25, 2005

4. No Sediment & Erosion Control Measures win 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, where
applicable, should be avoided during the October 15 to April 15 trout spawning
period to avoid adverse effects of sediment on eggs and larvae, where applicable.
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.

f\ very county:

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.

1 D. 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 3D-foot vegetated zone (in accordance with the WS-V
regulations), or the widest width that is practical under the site conditions, should 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 on ten (10) to twelve (12) foot centers. Stream banks in these

A very County:
Page 5 of6
July 25, 2005

areas should also be seeded with a native annual and perennial seed mix with a
temporary nursery crop of wheat, millet or other grain.

14.lf 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 30 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://h20.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.

;..,

1. Provide a written description of the proposed impacts: Impacts from this work will be
minimized whenever possible. However to accomplish these needed repairs impacts may be
realized from temporary increased turbidity. removal of aggraded bed material and temporary
loss of herbaceous vegetation. Long-term impacts will be an increase in stream bank
stability. stable dimension and profile. and improved vegetative cover.

draw-down valve or spillway, etc.):

Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):

Size of watershed draining to pond:

Expected pond surface area:

VII. Impact Justification (Avoidance and Minimization)

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
[mancial 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.
Access to each site will be over the most stable route possible and movement of vehicles over
access routes will be minimized. Wherever possible equipment work will be done from the
stream bank. Operating equipment within the channel will be done when this is the only way to
accomplish needed work. Excavated material will be moved directly to trucks for hauling to
disposal sites when it will not be used on site. When excavated material will be used on site it
will be handled as few times as possible. Work at each site will be accomplished as quickly as
possible and the site will be stabilized with erosion control matting and seeding within 5 days of
site completion. Trees will be planted during the next dormant season. Equipment leaking any
fluids will not be used and if leaks occur during construction the equipment will be replaced or
repaired immediately. Sediment and erosion control measures. including silt fence. stoned
entrances. protected stock pile areas. diversions and check dams. will be emploved to minimize
sediment movement off site.

VIII. Mitigation

DWQ - In accordance with l5A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for 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 - In 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.

Summary Evaluation of Conditions:
Reach begins downstream of the barn. Approximately 200' of channel aggraded during the floods and later was
dredged to keep the stream from flooding the house and other outbuildings. Downstream from the dredged area,
approximately 100' of channel are confined with minor bank slumping. The end of the reach has a small seep that
enters the stream from the left bank and moderately eroded left bank.

NRCS evaluated house and outbuildings at $150,000.
I
!

Recommendations for Improvements:
The upstream 200' of stream bank needs to be reshaped such that proper dimension adequately conveys stream flow
during high precipitation events. The banks should only need to be seeded, due to the cobbly material already on the
banks.
The downstream 100' of stream bank needs to be sloped, matted, and seeded. This will help convey the water and
help with slumping of the banks.
The left eroded bank needs to be sloped, matted, and seeded. Cobble from upstream should be placed along the toe
of the slope on the outside of the meander for extra toe protection. The small seep should have a rock lined outlet
where it meets Row Branch.

Subject: Cultural Resources Literature Search and Survey Results for Avery County NRCS Planned
EWP Undertakings

To: Jane Shaw, NRCS District Conservationist

Date of Survey: 6/14 - 15/2005

From: Jim Errante
USDA-NRCS, CRS SC & NC
1835 Assembly St., Rm 950
Columbia SC 29201
Phone: [phone]

The following list ofDSR's were reviewed by Jim Errante, NRCS Cultural Resources Specialist (CRS). A
literature search for each planed practice location took place in the Archaeological Map room ofthe NC Office
of State Archaeology. Each location was reviewed for the potential ofNRCS planned activities to effect
cultural resources (CR's). ill addition, photographs ofthe APE's were reviewed and discussions were held
with knowledgeable field office and the engineering staff in order to determine the potential of planned
activities to effect CR's at each EWP practice location. Each practice location received a ranking of a low,
medium or high potential to effect CR's.

All EWP practice locations receiving a medium or high ranking to effect cultural resources were
archeologically surveyed by the NRCS CRS. Archaeological survey procedures included reconnaissance
survey of all visible soils in the area including river bank profiles, and shovel testing. All shovel tested soils
were screened through ~ inch hardware mesh. The following Excel file list of EWP locations includes a
statement describing the results of this survey work. The NRCS CRS maintains the field work details of the
archaeological survey at each APE. Any questions concerning the results of these survey results as listed
below should contact the NRCS CRS for further explanation.

Erosion and Sediment Control Plan
Emergency Watershed Protection Program
Avery County

The following erosion and sediment control measures will be incorporated into all stream
repair sites.

1. The Contractor shall minimize vegetation disturbance by only working on the
stream bank and channel that is in need of repair. Existing buffers shall not be
disturbed unless directed by the designer.

2. . The Contractor shall only enter the stream channel as shown on the plans or
directed by the designer. These stream accesses shall conform to the design
standards shown in the attached detail drawings. Timber mats may be used as a
substitute for rock per the approval ofthe designer.

3. The Contractor shall limit all bank and channel disturbance to activities that can
be completed by the end of each working day such that the work would remain in
place during an overnight storm event.

4. All equipment and uninstalled materials shall be removed from the channel at the
end of each working day and secured safely from potential out-of-bank flow
events that may occur prior to performing additional work.

5. Graded stream banks shall be stabilized with temporary and permanent seed and
coir fiber matting at the end of each working day. Seeding and coir fiber
matting specifications are included with this plan.

6. Stockpiles shall remain at least fifteen feet from flowing water and outside ofthe
top of bank. Silt fence shall be placed at the base of the stockpile between the
stockpile and the channel and must function to receive stockpile runoffbefore
entering the channel. Silt fence shall conform to design standards shown in the
detail drawings.

7. Temporary vegetation and permanent herbaceous vegetation shall be established
on all disturbed areas not already stabilized with matting, within five days after
construction is completed.

8. Permanent woody vegetations species are listed in the vegetation specifications;
planting details are also included.

TECHNICAL SPECIFICATION

Vee:etation Plantine:

General Seeding
Seeding should be done immediately upon completion of final grading. Apply seed prior
to installing matting. Prepare the soil surface so that it is smooth and free from stones,
clods, or debris that will prevent the contact of the matting with the soil. Fertilizer and
lime are generally not necessary on most projects, particularly not on sites that have been
used for agriculture production or cattle grazing. Urban soils may require amendments.
Seed should be broadcast with a centrifugal seeder or by hand, at the full rate along
stream banks and in stockpile areas. In all areas where permanent seeding is used in
addition to the temporary seed, mixing ofthe seed for broadcasting is acceptable. Seed
and amendments (if needed) should be covered to a depth of 1/2 to 1 inch ,with soil by
using a hand rake, drag or other tillage equipment.

Seeding may also be done with a hydroseeder. Wood cellulose fiber will not be
acceptable as a substitute for straw mulch. A suitable tracer shall be used to clearly
identify areas hydroseeded. A minimum of 500 lbs. per acre of wood cellulose fiber or a
non-toxic water base dye may be used as a tracer. Seed shall not remain in water
containing fertilizer more than 45 minutes before being used. All products used to
hydro seed shall be non-toxic to aquatic organisms.

Temporary Seeding
For temporary seeding, apply the following vegetation at the listed rates and times.

Temporary Seeding (September to March):
Rye grain 3 lbs per 1,000 sq ft or

130 lbs per acre

Temporary Seeding (April to August):
Foxtail Millet lIb per 1,000 sq ft or

40 lbs per acre

A combination of the two temporary seed types shall be used during the boundary months
of March, April, August and September to ensure survival. In all disturbed areas where
no permanent seed is being used (i.e. yard or agricultural field) and temporary seed is not
desired at the higher rate, broadcast temporary seed at the lower rate of approximately 1/2
the fulllbs/acre stocking rate. When used in conjunction with permanent seed mix, apply
at ~ the fulllbs/acre rate.

Permanent Seeding
Permanent seeding will be accomplished using the mix listed below:

Trees shall be planted as either bare rooted or containerized material. Trees should be
planted at a rate of 400 stems/acre (roughly 10 feet on center) where EWP repairs have
been accomplished. Planting of this material will be done during the dormant season
(late fall and winter of2005-2006). Refer to the attached details and specifications for
more information.

Live Staking
Species used for live staking shall be taken from the following species:
Scientific name Common name
Comus amomum Silky Dogwood
Salix sericea Silky Willow
Sambucus canadensis Elderberry
Cephalanthus occidentalis Buttonbush
Salix nigra Black Willow

Stake at 2-3 foot spacing on the outside of all meander bends. Stake at 6-7 foot spacing
on the inside of meander bends and all tangent sections. Note this is appropriate for most
rural systems. Urban or flashy systems should be staked at higher rates. Utilize as
diverse a species group as feasible and make sure that black willow constitutes less than
25% of total stakes used.

Containerized Plants:
Containerized shrub material may also be used on the stream banks to increase the
diversity. Applications and spacing should reflect that of live stake material.

Mulching
Mulching shall be used to provide temporary protection of soil surfaces from erosion.
Mulching should be performed within 48 hours of seeding. Grain straw mulch should be
applied on seeded areas at a rate of75 bales per acre. Apply mulch uniformly.

at the toe of slope. The toe stakes shall have a minimum I-inch by I-inch cross-section
and shall be designed so that the matting can not slide past the exposed end of the stake.
Refer to the attached details and specifications for EWP work for more information.

Coir Fiber Matting
The erosion control matting shall be a machine-produced mat of 100% coconut fiber with
the following properties:
Matrix 100% Coconut Fiber
Weight 20 oz/SY (678 gm/m2)
Tensile Strength 1348 x 6261b/ft minimum (1650.5 x 766.5 kg/m)
Elongation 34% x 38%
Open Area (measured) 50%
Thickness 0.30 in minimum (7.6 mm)
Flexibility (mg -em) 65030 x 29590
Recommended Flow 11 feet/second (3.35 m1s)
Size 6.6 x 164 ft (120 SY) or (100 SM)
"C" Factor 0.002
Place the coir fiber matting immediately upon final grading. Provide a smooth soil
surface free from stones, clods, or debris that will prevent the contact of the matting with
the soil. Apply seed prior to installing matting. Begin at the bottom ofthe slope by
anchoring the matting in a 6-inch (15 cm) deep by 6-inch (15 cm) wide trench. Backfill
and compact the trench after staking. Walking backward down the stream, allow the
matting to unroll slowly; ideally the matting roll will rest against your shin as you walk.
Stake the matting according to recommended stake pattern for specific product and slope.
(See stake pattern guide that comes with the product.) Place matting in full contact with
the soil.

The edges ofthe parallel matting must be staked with approximately 2 inches (5 cm) of
overlap such that the edge of the downstream matting is under the one just upstream.
When matting must be spliced down the slope, place matting end over end (shingle style)
with approximately 6 inches overlap. Drive stakes through the overlapped area.

Place stakes across the matting at ends, junctions and trenches approximately 1.3 ft apart.
Place stakes along the outer edges, down the center of each strip of matting and along all
lapped edges approximately 2 ft apart. Cut excess matting and anchor at the end ofthe
slope.

Temporary Stream Access Ramps
Stream access ramps shall be constructed using either rock or timber mats in locations as
shown on the plans or as directed. Grading shall be performed only to the extent needed
to form a stable ramp connecting the stream bank grade to the streambed. The Contractor
shall determine the appropriate number of timber mats and ramp angle according to the
equipment that will be using the ramp. Stream access ramps are temporary and shall be
removed and the areas restored to their original state when they are no longer needed or
permanent measures are installed.

Sediment Fence
Geotextile sediment fences shall be used to trap sediment from areas of limited runoff.
Sediment fences shall be properly anchored to prevent erosion under them. These works
are temporary and shall be removed and the areas restored to their original state when
they are no longer needed or permanent measures are installed. Locations for sediment
filters are shown on the plans. Refer to sediment fence specifications (6,62) in the NC
Erosion and Sediment Control Planning and Design Manual for material and installation
requirements.

Gravel Construction EntrancelExit
Temporary gravel construction entrances shall be constructed as shown on the plans and
according to specification 6.06 of the NC Erosion and Sediment Control Planning and
Design Manual.

In-stream Structures
In-stream structures include w-weirs, cross vanes, j-hook vanes, log vanes, and wing
deflectors. The quantity of in-stream structures to be constructed shall follow approved
plans, but may be affected by conditions encountered during construction

Boulders used for in-stream structures shall be relatively flat on either side in the same
dimension, preferably the long dimension, and must have relatively smooth ends. No
more than 5% of the boulders shall be smaller than 3 'x2 'x2'. Boulders larger than
6'x4'x3' shall be permitted. Boulders found on-site and approved for use by the
Developer will be used to the extent feasible.

The Contractor shall construct in-stream structures with equipment capable of moving
and accurately placing boulders of approximate dimensions 6'x4'x3'. If suitable for
backfill, excavated material shall be placed on the upstream side of structures or as
directed. Unless otherwise approved by the Developer, excavation to prepare the
subgrade for the installation of in-stream structures shall be consecutive and continuous.
Once the excavation of a structure has begun, the structure shall be completed by the end
of the workday. All equipment shall be removed from the stream at the end of each
workday. Any accumulation of sediment in the channel shall be cleaned as needed
during construction and at the end of construction. No separate payment will be made for
this clean-up work.

Construction Sequence of Events
Construction shall be performed at the EWP site in accordance with the plans and in
general accordance with the following sequence:

1. Mobilize equipment and materials to the site.
2. Set up construction access pads, staging areas, haul roads, and silt fences.
3. Install stream access ramps.
4. Excavate and grade banks and construct in-stream structures.
5. Seed and mat graded banks and immediately upon reaching final grades.
6. Stabilize all disturbed soil with temporary and permanent seed prior to leaving the
site each day and prior to moving to the next work area.
7. Dispose of excess materials at approved off-site locations.
8. Remove stream access ramps.
9. Remove silt fence and seed and mulch staging areas to restore these areas to pre-
project conditions.
10. Demobilize grading equipment from the site. Remove construction access pads.
11. Plant bank, floodplain and buffer woody vegetation and live stakes during the
dormant season.
