Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:
The proposed site consists of light residential uses. The stream and stream banks were
heavily impacted during Tropical Storms Frances and Ivan. Extensive stream bank erosion
threatens the stability of existing structures.
9. Describe the overall project in detail, including the type of equipment to be used:
EWP 200-123
This project area includes approximately 200 linear feet of an unnamed tributary to Dix
Creek adjacent to Dix Creek No. 1 Road. The project area is located at 35°3643.4"N
82°39'45.4"W. Highwater flows have severely eroded the banks. In this section of creek two
property access roads are threatened by these conditions. Attachment 1 contains
representative photos of the project area.
Repairs in this reach of stream will involve the following:
- Stabilize the channel in its pre-flood configuration using organic and rock structures
- Reseed and plant woody vegetation
The techniques that will be utilized for the proposed repairs at the EWP site listed
above are described below.
Streambank Repair
When possible, excavation equipment will access streambank repair areas from the dry and
will not track into the stream channel. Most of the steep eroded streambanks are opposite or
adjacent to the debris removal areas. At these areas, the rocky material removed from the
floodplain will be used to stabilize the stream bank, with the addition of large boulders along
the toe of the slope as necessary to stabilize and protect the toe. Where suitable material is
available, rock vane and root wads will be installed in the restored bank section to reduce
bank stress and provide stability to the unconsolidated fill.
An existing cross section and site specific design components are included in Attachment 1
for each of the impacted channel sections requiring stabilization. Drainage areas of project
areas are also included in those attachments. The drainage area is used to determine the
design storm peak flow using USGS Rural Regression equations for the Blue Ridge-
Piedmont. Design storm velocity and shear stress values were also calculated. This
information, in conjunction with the field investigation analysis, DSR notations, and agency
guidance and regulations, are used to develop an appropriate streambank stabilization design.
Additional information on general design features, erosion control practices and debris
removal practices is included in Attachment 2.
Equipment that may be used to accomplish the above listed tasks includes; rubber tired
skidders, 15 ton dump truck, hydraulic track mounted excavator with thumb, and chainsaws.
Page 3 of 10
10. Explain the purpose of the proposed work:
The work addressed in this application is intended to improve post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are
threatening structures or other property. The proposed actions are not intended to enhance
existing conditions or restore 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.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.

local stormwater requirement, etc.): NA
Size of watershed draining to pond: NA Expected pond surface area: NA
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
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.
When at all possible equipment will be kept out of the stream channel, stream crossings will be
minimized, and no excavation will be below the existing channel bed. When at all possible
stream material will be moved from dry areas to banks, minimizing the movement of wet (or
below water line) stream material. Creating wide, shallow channels will be avoided. Temporary
and/or permanent herbaceous vegetation shall be planted on all bare soil within 15 days of
ground disturbing activities. Rocky material shall not be used for bank stabilization above the
normal high water mark. Large rocky material will be brought in to stabilize the toe of impacted
streambanks where necessary.
VIII. Mitigation
DWQ - In accordance with 15A 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.
Page 6 of 10
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.
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/stnnaide.htmi.
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)

1. Conduct soil test to confirm necessary lime and fertilizer
amendments. Appropriate lime and fertilizer shall be
applied prior to seeding and incorporated to a depth 3 to 5
inches below the surface.
2. Temporary stabilization will be applied to all disturbed
areas on a daily basis. Areas shall be seeded with rye
grass at a rate of 15 lbs./ac. and long straw or hay
mulched. Straw shall consist of thoroughly threshed wheat,
rye or oat straw, reasonably bright in color, and shall not
be musty, moldy, caked, decayed, or excessively dusty
and shall be free of noxious weed seeds.
3. Permanent soil stabilization shall be completed within 7
calendar days of initial soil disturbance or re-disturbance.
Planting and seeding shall be incorporated into the subsoil
at the rates prescribed on Figures 6, 7, and 8. Contractor
shall follow NCDWQ Guidelines for Riparian Restoration,
http://h2o.enr.state.nc.us/wrp/pdf/buffers.pdf
4. All earth fill in excess of 1 ft depth should be installed in
lifts of maximum 6-inches and mechanically compacted.
5. All rock used for bank stabilization and in-stream structures
shall be 3 ft to 4 ft angular rock.
6. Erosion Control (EC) Fabric shall be woven coir mat,
secured with dead stout stakes, and shall meet the
following standards:
50% open area (maximum)
0.5 inch maximum opening size
4.5 lbs. per sq. foot maximum sheer stress
10 fps minimum velocity

THE RESTRICTION ON THE TITLE PAGE OF THIS PROPOSAL.
7. Filter fabric shall be Amoco Propex 2002 woven geotextile
or equivalent. Cut excess filter fabric so no fabric is visible
after installation.
8. Seeded areas not specified for coir fabric, shall be
mulched with long straw or hay mulch immediately after
seeding areas at a rate of 2 tons/acre (uniform loose depth
of 1" to 2"). Straw shall consist of thoroughly threshed
wheat, rye or oat straw, reasonably bright in color, and
shall not be musty, moldy, caked, decayed, or excessively
dusty and shall be free of noxious weed seeds. Mulch
shall be secured with biodegradable netting (Robex Super
Flow or Equal).
9. The Contractor shall be responsible for maintaining seeded
areas until 95% vegetative cover is established. Should
any seeded area fail to germinate, or washing of any areas
occur requiring re-establishment of seeding, the Contractor
shall replace any lost soil material and re-seed and
re-mulch such areas at Contractor's expense.
Standard Erosion and Sediment Control Notes
1. The Contractor shall protect all points of construction
ingress and egress by installing a temporary construction
entrance as shown in details to prevent the deposition of
materials onto public roads. All materials deposited onto
public roads shall be removed immediately.
2. The Contractor shall re-vegetate or restore access roads
(including construction entrance) to match pre-construction
conditions.
3. The Contractor shall inspect daily and maintain
continuously in an effective operating condition all erosion
and sediment control measures until such times as they
are removed with prior permission from Engineer or
agency inspector.
4. The Contractor shall protect trees and landscaping not
marked for disposal from damage. Any damage that
occurs shall be repaired at the Contractor's expense.
5. Fencing shall be maintained for animal containment. The
Contractor shall provide temporary fencing to allow for

Representative cannot authorize additional work. Any work that will result in an increase in
cost must be submitted to CH2M HILL for approval prior to starting such work. In the event
that the contractor uses on-site chipping, the chipper may follow the clean-up crew along the
length of the project reach. The Contractor is responsible to properly dispose of chips.
Proper disposal may include spreading on site or removing off-site. On-site disposal requires
written approval by the property owner. Unless specifically requested to leave the chips in a
pile by a property owner the chipper shall make reasonable efforts to spread the chips as
chipping progresses.
Chippers and other heavy equipment will be staged and used at least 30-feet from the top of
the streambank or on existing paved or graveled areas prepared in accordance with standard
details described in Figure 18 (see Typical Design Drawings).
Repair of any property damage resulting from debris removal is the sole responsibility of the
Contractor.
All debris removal shall be within the included sites as identified in this solicitation and as
directed by the Representative. For bid preparation purposes, the Representative has
marked and identified debris to be removed. Removed debris shall be placed only in
those areas as directed by the Representative. For Bid purposes, debris staging areas are
assumed to be within 300 feet of top of bank. On-site burning is not allowed. Fallen
trees, limbs and dislodged brush within the cross section of the existing or original
channel up to and including the debris line of the subject storm shall be removed. Any
foreign (man-made) debris washed in from upstream, shall be removed. Marked trees
severely undercut by stream bank erosion and trees severely leaning over the channel
whose near term fall is apparent shall be removed.
In general, Contractor clearing will be limited to the cutting of severely damaged trees
leaning across the channel, and other trees as needed to gain access for equipment to points
of channel blockage.

Disturbance of the channel bottom and banks, and equipment access areas shall be held
to the minimum necessary to allow the construction equipment to remove the debris and
shall be consistent with all state and federal permits. All areas disturbed due to debris
removal or equipment access shall be reshaped and reseeded in accordance with
standard details described in Figures 7-18 (see Typical Design Drawings).
Access to the channel will generally be perpendicular to the channel so cutting of trees is
held to a minimum with precaution taken to protect mast producing and stream canopy
trees. Un-marked dead trees that provide den habitat and are determined to pose no
hazard to the channel shall be protected. As such, the contractor will only remove marked
debris. The contractor will exercise care in the areas of existing crops to minimize
damages.
PROVIDED EQUIPMENT & FACILITIES
The Contractor shall provide adequate sanitary facilities for equipment operators and
work crews. Portable facilities shall be provided at the worksite and arrangements made
for proper servicing. A portable facility will be provided within 1,000 feet of the
equipment and/or work crews at all times.

Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:
The proposed site consists of light residential uses. The stream and stream banks were
heavily impacted during Tropical Storms Frances and Ivan. Extensive stream bank erosion
threatens the stability of existing structures.
9. Describe the overall project in detail, including the type of equipment to be used:
EWP 2005-123
This project area includes approximately 200 linear feet of an unnamed tributary to Dix
Creek adjacent to Dix Creek No. 1 Road. The project area is located at 35°3643.4"N
82°39'45.4"W. Highwater flows have severely eroded the banks. In this section of creek two
property access roads are threatened by these conditions. Attachment 1 contains
representative photos of the project area.
Repairs in this reach of stream will involve the following:
- Stabilize the channel in its pre-flood configuration using organic and rock structures
- Reseed and plant woody vegetation
The techniques that will be utilized for the proposed repairs at the EWP site listed
above are described below.
Streambank Repair
When possible, excavation equipment will access streambank repair areas from the dry and
will not track into the stream channel. Most of the steep eroded streambanks are opposite or
adjacent to the debris removal areas. At these areas, the rocky material removed from the
floodplain will be used to stabilize the stream bank, with the addition of large boulders along
the toe of the slope as necessary to stabilize and protect the toe. Where suitable material is
available, rock vane and root wads will be installed in the restored bank section to reduce
bank stress and provide stability to the unconsolidated fill.
An existing cross section and site specific design components are included in Attachment 1
for each of the impacted channel sections requiring stabilization. Drainage areas of project
areas are also included in those attachments. The drainage area is used to determine the
design storm peak flow using USGS Rural Regression equations for the Blue Ridge-
Piedmont. Design storm velocity and shear stress values were also calculated. This
information, in conjunction with the field investigation analysis, DSR notations, and agency
guidance and regulations, are used to develop an appropriate streambank stabilization design.
Additional information on general design features, erosion control practices and debris
removal practices is included in Attachment 2.
Equipment that may be used to accomplish the above listed tasks includes; rubber tired
skidders, 15 ton dump truck, hydraulic track mounted excavator with thumb, and chainsaws.
Page 3 of 10
10. Explain the purpose of the proposed work:
The work addressed in this application is intended to improve post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are
threatening structures or other property. The proposed actions are not intended to enhance
existing conditions or restore 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.

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.
When at all possible equipment will be kept out of the stream channel, stream crossings will be
minimized, and no excavation will be below the existing channel bed. When at all possible
stream material will be moved from dry areas to banks, minimizing the movement of wet (or
below water line) stream material. Creating wide, shallow channels will be avoided. Temporary
and/or permanent herbaceous vegetation shall be planted on all bare soil within 15 days of
ground disturbing activities. Rocky material shall not be used for bank stabilization above the
normal high water mark. Large rocky material will be brought in to stabilize the toe of impacted
streambanks where necessary.
VIII. Mitigation
DWQ - In accordance with 15A 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.
Page 6 of 10
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.
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

PERMIT FOR EMERGENCY WATERSHED PROTECTION (EWP)
The undersigned landowners hereby grant permission to Buncombe County and the Buncombe
County Soil and Water Conservation District and/or their agents to enter upon our land for the
purpose of repairing the flood damage of stream channels and stream banks in the
IV 01 t^m G U' GC.k watershed.
This permit includes the right to spread soil, remove and dispose of debris, install needed
measures, seed and mulch, and perform similar emergency watershed protection work
necessitated by the floods of September, 2004.
This permit also includes the right of ingress and egress on the land for the purpose of
maintaining or inspecting maintenance of the emergency works for the period of 1 year from the
date of completion. Work areas covered by this permit are sketched on the reverse of this form
or on an attached sheet.

Debris Removal SOP
General Notes
The Contractor shall make his own determination of the
existing subsurface conditions. In areas where proposed
construction may conflict with existing utilities, the Contractor
shall take all necessary precautions to avoid damage to the
utilities. Notify and locate all impacted utilities at least 48
hours prior to excavation. Any damage sustained to utilities
shall be repaired by or under the direction of the utility owner
at the Contractor's expense.
All existing facilities, including but not limited to sidewalks,
roads, lawns, landscape vegetation, etc., inside and outside of
construction limits that are disturbed under this contract shall
be reestablished and/or reconstructed to the original condition
at the Contractor's expense.
Construction Sequence
1. Begin work at the upstream end of the project reach.
2. Construct proposed structures according to the plans and
specifications.
3. Grade stream banks to proposed grade, and tie into
existing banks upstream and downstream.
4. Overbank areas (beyond top of bank) adjacent to the
project reach shall be graded for positive drainage toward
the stream.
5. Apply temporary stabilization to the disturbed areas at the
end of each work day.
6. Repeat steps 1 through 5 for each segment of the project
reach, working downstream.
Site Stabilization
1. Conduct soil test to confirm necessary lime and fertilizer
amendments. Appropriate lime and fertilizer shall be
applied prior to seeding and incorporated to a depth 3 to 5
inches below the surface.
2. Temporary stabilization will be applied to all disturbed
areas on a daily basis. Areas shall be seeded with rye
grass at a rate of 15 lbs./ac. and long straw or hay
mulched. Straw shall consist of thoroughly threshed wheat,
rye or oat straw, reasonably bright in color, and shall not
be musty, moldy, caked, decayed, or excessively dusty
and shall be free of noxious weed seeds.
3. Permanent soil stabilization shall be completed within 7
calendar days of initial soil disturbance or re-disturbance.
Planting and seeding shall be incorporated into the subsoil
at the rates prescribed on Figures 6, 7, and 8. Contractor
shall follow NCDWQ Guidelines for Riparian Restoration,
http://h2o.enr.state.nc.us/wrp/pdf/buffers.pdf
4. All earth fill in excess of 1 ft depth should be installed in
lifts of maximum 6-inches and mechanically compacted.
5. All rock used for bank stabilization and in-stream structures
shall be 3 ft to 4 ft angular rock.
6. Erosion Control (EC) Fabric shall be woven coir mat,
secured with dead stout stakes, and shall meet the
following standards:
50% open area (maximum)
0.5 inch maximum opening size
4.5 lbs. per sq. foot maximum sheer stress
10 fps minimum velocity
CLT/GENERAL NOTES_NF.DOC
USE OR DISCLOSURE OF DATA CONTAINED ON THIS SHEET IS SUBJECT TO
THE RESTRICTION ON THE TITLE PAGE OF THIS PROPOSAL
7. Filter fabric shall be Amoco Propex 2002 woven geotextile
or equivalent. Cut excess filter fabric so no fabric is visible
after installation.
8. Seeded areas not specified for coir fabric, shall be
mulched with long straw or hay mulch immediately after
seeding areas at a rate of 2 tons/acre (uniform loose depth
of 1" to 2"). Straw shall consist of thoroughly threshed
wheat, rye or oat straw, reasonably bright in color, and
shall not be musty, moldy, caked, decayed, or excessively
dusty and shall be free of noxious weed seeds. Mulch
shall be secured with biodegradable netting (Robex Super
Flow or Equal).
9. The Contractor shall be responsible for maintaining seeded
areas until 95% vegetative cover is established. Should
any seeded area fail to germinate, or washing of any areas
occur requiring re-establishment of seeding, the Contractor
shall replace any lost soil material and re-seed and
re-mulch such areas at Contractor's expense.
Standard Erosion and Sediment Control Notes
1. The Contractor shall protect all points of construction
ingress and egress by installing a temporary construction
entrance as shown in details to prevent the deposition of
materials onto public roads. All materials deposited onto
public roads shall be removed immediately.
2. The Contractor shall re-vegetate or restore access roads
(including construction entrance) to match pre-construction
conditions.
3. The Contractor shall inspect daily and maintain
continuously in an effective operating condition all erosion
and sediment control measures until such times as they
are removed with prior permission from Engineer or
agency inspector.
4. The Contractor shall protect trees and landscaping not
marked for disposal from damage. Any damage that
occurs shall be repaired at the Contractor's expense.
5. Fencing shall be maintained for animal containment. The
Contractor shall provide temporary fencing to allow for
execution of the work. The Contractor shall keep
construction equipment away from livestock and take all
precautions to prevent injury to animals.

Organic Debris Removal
Standard Operation Procedures (SOP)
Emergency Watershed Protection (EWP) Stream Repair Projects
Buncombe County, North Carolina
SCOPE OF WORK
The work shall consist of the cleanup of designated stream areas by the removal and
disposal of trees, logs, stumps, brush, tops, rubbish, and other debris deposited in the
stream channel and floodplain by the storms of September 8 and 16, 2004.
CLEARING AND DEBRIS REMOVAL
Debris removal crews shall remove only that material which has been clearly marked by a
representative of Buncombe County and/or CH2M HILL, INC (Representative) as indicated
by flagging and/or orange/red spray paint. ONLY marked debris is to be removed.
Representative cannot authorize additional work. Any work that will result in an increase in
cost must be submitted to CH2M HILL for approval prior to starting such work. In the event
that the contractor uses on-site chipping, the chipper may follow the clean-up crew along the
length of the project reach. The Contractor is responsible to properly dispose of chips.
Proper disposal may include spreading on site or removing off-site. On-site disposal requires
written approval by the property owner. Unless specifically requested to leave the chips in a
pile by a property owner the chipper shall make reasonable efforts to spread the chips as
chipping progresses.
Chippers and other heavy equipment will be staged and used at least 30-feet from the top of
the streambank or on existing paved or graveled areas prepared in accordance with standard
details described in Figure 18 (see Typical Design Drawings).
Repair of any property damage resulting from debris removal is the sole responsibility of the
Contractor.
All debris removal shall be within the included sites as identified in this solicitation and as
directed by the Representative. For bid preparation purposes, the Representative has
marked and identified debris to be removed. Removed debris shall be placed only in
those areas as directed by the Representative. For Bid purposes, debris staging areas are
assumed to be within 300 feet of top of bank. On-site burning is not allowed. Fallen
trees, limbs and dislodged brush within the cross section of the existing or original
channel up to and including the debris line of the subject storm shall be removed. Any
foreign (man-made) debris washed in from upstream, shall be removed. Marked trees
severely undercut by stream bank erosion and trees severely leaning over the channel
whose near term fall is apparent shall be removed.
In general, Contractor clearing will be limited to the cutting of severely damaged trees
leaning across the channel, and other trees as needed to gain access for equipment to points
of channel blockage.
PABuncombeCountyNc\328275\Permits\Newfound PCNs\Final PCNs and Attachments\Design
Attachments\Buncombe Debris Removal SOP.doc
Disturbance of the channel bottom and banks, and equipment access areas shall be held
to the minimum necessary to allow the construction equipment to remove the debris and
shall be consistent with all state and federal permits. All areas disturbed due to debris
removal or equipment access shall be reshaped and reseeded in accordance with
standard details described in Figures 7-18 (see Typical Design Drawings).
Access to the channel will generally be perpendicular to the channel so cutting of trees i
held to a minimum with precaution taken to protect mast producing and stream canop
trees. Un-marked dead trees that provide den habitat and are determined to pose no
hazard to the channel shall be protected. As such, the contractor will only remove marked
debris. The contractor will exercise care in the areas of existing crops to minimize
damages.
PROVIDED EQUIPMENT & FACILITIES
The Contractor shall provide adequate sanitary facilities for equipment operators and
work crews. Portable facilities shall be provided at the worksite and arrangements made
for proper servicing. A portable facility will be provided within 1,000 feet of the
equipment and/or work crews at all times.
COMMUNICATIONS
Each mechanized piece of equipment and each work crew shall be equipped with a two
way, battery operated radio. Radios shall be FM, have a minimum range of 5 miles.
Radios shall be maintained "on" and in the receive mode at all times while the operator Is
at the site. Batteries shall be recharged overnight or as needed. An extra set of fully
charged batteries shall be maintained on board the equipment at all times. Radios shall
be equipped with clip-on hand mikes or headsets. Radios shall be maintained in good
operating condition and equipment operators shall be knowledgeable in the use and care
of the radios. Each Contractor site supervisor shall also maintain a secondary
communication system compatible with the Representative's system.
Brush Removal Guidelines
• Small diameter brush and limbs (less than four inches in diameter) that will not
cause damage if remobilized by high water will be cut into short lengths (five feet
long or less) and left in place.
• All marked, dislodged or uprooted larger diameter brush will be removed from
the channel or streambank and chipped in designated areas greater than 30-feet
from the top of the bank.
• Saplings and shrubs with an intact root system are not to be removed.
P:\BuncombeCountyNc\328275\Permits\Newfound PCNs\Final PCNs and Attach ments\Dcsign
Attachments\Buncombe Debris Removal SOP.doc
Tree Removal Guidelines
• Trees will be chipped in designated areas greater than 30-feet from the top of the
streambank. Chippers and/or tub grinders may be staged on-site with written
consent from the property owner or at a central location approved by the County.
• Larger diameter trees may be pulled to the chipper using a mechanized winch
provided the process does not create excess disturbance to the streambank.
• Marked trees whose near term fall is apparent should be cut at the marked
location, which will be indicated by a painted ring around the trunk at least three-
feet above the ground surface. The root system shall not be removed from the
streambank.
• As approved by the Representative, larger diameter trees that cannot be moved
using hand equipment will be cut to manageable lengths and removed.
• The sale of chips or firewood is not allowed.
Foreign Debris and Trash Removal Guidelines
• Foreign (manmade) debris and trash will be bagged in orange trash bags where
possible.
• Filled trash bags will be removed from the channel and transported directly
offsite by the Contractor to a local landfill.
• Large debris must be loaded into a dump truck or roll-off container and
transported to a local landfill for disposal.
• Tipping fees for disposal shall be paid by the Contractor.
Stream bed and Bank Repair Guidelines
• All temporary stream crossings shall be installed as described in Figures 15 -18
(see Typical Design Drawings).
• All Stream embankments disturbed by Contractor activities, denuded, or left bare
as a result of debris removal shall be regraded, planted, and erosion control fabric
installed as described in Figures 6, 7, and 9 - 12 (see Typical Design Drawings).
Temporary staging, chipping, and work access points shall be regraded and
grassed using a native grass/herb mix as outlined in Figures 6, 7, and 16 - 18 (see
Typical Design Drawings).

RE: Emergency Watershed Protection Stream-Clearing Projects
Dear
I know that County experienced stream damage as a result of the fall
hurricanes. Our department would like to work closely with your county to insure that
stream restoration projects receiving state and federal funds under the Emergency
Watershed Protection (EWP) program move as smoothly as possible through the
environmental review and permitting process. I have enclosed for your information a
brief summary of the types of permits and approvals that may be required for these
projects. For projects that involve work directly affecting the streambed, the United
States Army Corps of Engineers will be the primary environmental permitting agency.
For those projects, our staff in the Division of Water Quality and the Division of Land
Resources play a supporting role and issue related state approvals.
I have asked our staff to meet with all of the western counties, either individually or in
small groups, to talk about each county's proposed stream restoration projects and answer
your questions about permit requirements. Our staff will ask the Corps of Engineers and
Soil and Water Conservation staff to join in those meetings in an effort to put together a
plan of action for reviewing and approving stream restoration projects as quickly as
possible. You should receive a telephone call from DENR staff soon to talk about a date
and time that would be convenient to meet and talk about your projects.
I have also directed our staff to waive fees for state water quality certifications (under
Section 401 of the Clean Water Act) and for approval of erosion and sedimentation
February 25, 2005
Page 2 of 2
control plans for stream-clearing projects funded under EWP. Fees will be waived for all
EWP pen-nit s requested by September 1, 2005.
I hope these efforts will ease the burden on county governments already challenged by
the demands of reconstruction and recovery. If we can help you in any other way, please
do not hesitate to call. I have asked Assistant Secretary Robin Smith to be a,primary
contact on these projects for DENR; you can reach Ms. Smith at [phone]. The
enclosed information sheet also provides contact information for DENR staff in both the
Asheville and Winston-Salem Regional Offices and for the Corps of Engineers office in
Asheville.
Sincerely,
William G. Ross, Jr.
