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.

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.
Yancey County:
Page 3 of 6
October 7, 2005
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:

October 7, 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 30-foot Water Supply Watershed 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
on 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:

October 7, 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 30 feet (in
accordance with the Water Supply Watershed Regulations) 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
401NVetiands 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 of the proposed project site consists of agricultural uses and
residential uses. This portion of Cane River was impacted during Tropical Storms Frances
and Ivan. The streambank was eroded during the flooding, and is currently unstable.
9. Describe the overall project in detail, including the type of equipment to be used:
This Pre-Construction Notification form addresses one area of streambank stabilization on
DSR 23. The area is located on Samuel Riddles property. The area addressed by this submittal
is entirely located on the parcels shown on Figure 2, and detailed in Table 1.
Since the area is entirely located on agricultural land a formal approval of the Erosion and
Sediment Control Plan elements of this proposal is not required, nor is a Trout Waiver
required.
The left bank has eroded in the vicinity of a large barn. The channel is approximately 50-feet
closer to the barn post- flood than it was pre flood. The river is extremely braided in this area.
There are now three distinct channels running adjacent to the Samuel Riddle property. The far
west channel has become the primary channel, which is eroding the bank and encroaching
upon the barn.
All work will be performed as per conversations between Altamont Environmental, USArmy
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 area described below as well as localized removal oforganic
and mineral debris and streambank re-vegetation.
Cane River is classified as `WSII ; `Trout' waters and High Quality Waters (HQ U9 throughout
the project area. No listed species or their habitats occur in this area according to the US Fish
and Wildlife Service response to the EWP Environmental Checklist on February 2, 2005.
The overall goals of work at this location are to
1. Stabilize the channel in the post flood condition, directing low flows to river-right while
allowing storm flows to engage the river left channel.
2. Re-establish the channel on the east (right) side of the inset valley. The channel geometry
and cross-sectional area will be based on evaluation of relatively undisturbed portions of the
Cane River upstream and downstream of the site.
3. Provide a medium to high flow channel in the river left portion of the channel.
4. Protect the barn on the west side of the valley.
To accomplish these goals, it will be necessary to utilize a combination of rock rip-rap,
bioengineering, in-stream structures, and channel bed excavation.
The work addressed in this application is intended to improve the post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are threatening
structures. 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.
Equipment used to accomplish the above tasks includes: one or more 15 ton dump trucks, one
or more hydraulic track mounted excavators with thumb, one or more dozers with a six-way
blade; and chainsaws.
Establishment of vegetation on the disturbed channel banks will be necessary in some locations
in the vicinity. Vegetation establishment will consist of a combination of hydroseeding and live
staking.
A primary concern for the excavation of channel bed materials is the impact to turbidity within
the Cane River. It may be possible to separate excavators from flow via the use of temporary
berms, pipes, and water pumps. However, given the significant quantities of water in the system,
and the high permeability of soils in this reach, excavating the channel bed in this location with
the excavators out of the water is impractical. Therefore, the work will be sequenced without
attempt to separate the equipment from flowing water, and attention will be focused on an
efficient work pattern that will limit the time necessary for equipment to be in the water. The
following construction sequence will be utilized.
At all areas the work will proceed from downstream to upstream to reduce sediment loading. All
staging areas will be less than half an acre in size. Work will 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%xits, where, necessary.
4. Install sediment fence around staging areas.
5. Install sand bag berm to direct all flow into the western (river-left) channel.
6. Install second sand bag berm at the downstream end of the eastern channel to prevent
backwater from the western channel.
7. Excavate the river-right channel at the upstream extent of repair.
8. Modify sand bag berm to direct flow to the right.
9. Install in-stream rock sill structure. The rock sill structure will allow flows to engage the
river-left channel at higher stages.
10. At the end of each workday install temporary erosion control fabric or matting on exposed
soil and secure using removable stakes or sandbags.
11. During construction, place large boulders at the toe of repaired streambanks where
necessary.
4
12. Fill and compact behind boulders. Cover with topsoil, install erosion control mat, and seed.
Permanent erosion control mats will be constructed offiber or a coir fiber mixture fabric
for maximum erosion protection, vegetation establishment assistance, and for minimal
impact on wildlife.
13. 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, coir logs, large woody material, and natural fiber erosion control mats will be
used for streambank stabilization.
Once site construction has ceased, the banks of the stabilized channel will be seeded with a
native floodplain seed mix and the high stress areas with a slope of 2:1 or greater 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 15-20 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/grasses. All disturbed areas will be seeded with a temporary
native grass mixture immediately following completion of the work in those areas. Straw
mulch and tall fescue will not be used in riparian areas.
3. When possible sod will be taken from adjacent 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 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

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 of 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 of the stream channel. Teinporary grass cover shall be planted on all bare soil
within 5 days of ground 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 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.

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 uses and
residential uses. This portion of Cane River was impacted during Tropical Storms Fiances
and Ivan. The streambank was eroded during the flooding, and is currently unstable.
9. Describe the overall project in detail, including the type of equipment to be used:
This Pre-Construction Notification form addresses one area of streambank stabilization on
DSR 23. The area is located on Samuel Riddles property. The area addressed by this submittal
is entirely located on the parcels shown on Figure 2, and detailed in Table 1.
Since the area is entirely located on agricultural land a formal approval of the Erosion and
Sediment Control Plan elements of this proposal is not required, nor is a Trout Waiver
required.
The left bank has eroded in the vicinity of a large barn. The channel is approximately 50-feet
closer to the barn post- flood than it was pre flood. The river is extremely braided in this area.
There are now three distinct channels running adjacent to the Samuel Riddle property. The far
west channel has become the primary channel, which is eroding the bank and encroaching
upon the barn.
All work will be performed as per conversations between Altamont 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 area described below as well as localized removal of organic
and mineral debris and streambank re-vegetation.
Cane River is classified as `WSII, `Trout' waters and High Quality Waters (HQT9 throughout
the project area. No listed species or their habitats occur in this area according to the US Fish
and Wildlife Service response to the EWP Environmental Checklist on February 2, 2005.
The overall goals of work at this location are to
1. Stabilize the channel in the post flood condition, directing low flows to river-right while
allowing storm flows to engage the river left channel.
2. Re-establish the channel on the east (right) side of the inset valley. The channel geometry
and cross-sectional area will be based on evaluation of relatively undisturbed portions of the
Cane River upstream and downstream of the site.
3. Provide a medium to high flow channel in the river left portion of the channel.
4. Protect the barn on the west side of the valley.
To accomplish these goals, it will be necessary to utilize a combination of rock rip-rap,
bioengineering, in-stream structures, and channel bed excavation.
The work addressed in this application is intended to improve the post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are threatening
structures. 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.
Equipment used to accomplish the above tasks includes: one or more 15 ton dump trucks, one
or more hydraulic track mounted excavators with thumb, one or more dozers with a six-way
blade; and chainsaws.
Establishment of vegetation on the disturbed channel banks will be necessary in some locations
in the vicinity. Vegetation establishment will consist of a combination of hydroseeding and live
staking.
A primary concern for the excavation of channel bed materials is the impact to turbidity within
the Cane River. It may be possible to separate excavators from flow via the use of temporary
berms, pipes, and water pumps. However, given the significant quantities of water in the system,
and the high permeability of soils in this reach, excavating the channel bed in this location with
the excavators out of the water is impractical. Therefore, the work will be sequenced without
attempt to separate the equipment from flowing water, and attention will be focused on an
efficient work pattern that will limit the time necessary for equipment to be in the water. The
following construction sequence will be utilized.
At all areas the work will proceed from downstream to upstream to reduce sediment loading. All
staging areas will be less than half an acre in size. Work will proceed as follows at each work
area (as applicable):
1. Flag the work limits.
Z Mark live trees and shrubs to be protected.
3. Construct temporary construction entrancelexits, where necessary.
4. Install sediment fence around staging areas.
5. Install sand bag berm to direct all flow into the western (river-left) channel.
6. Install second sand bag berm at the downstream end of the eastern channel to prevent
backwater from the western channel.
7. Excavate the river-right channel at the upstream extent of repair.
8. Modify sand bag berm to direct flow to the right.
9. Install in-stream rock sill structure. The rock sill structure will allow flows to engage the
river-left channel at higher stages.
10. At the end of each workday install temporary erosion control fabric or matting on exposed
soil and secure using removable stakes or sandbags.
11. During construction, place large boulders at the toe of repaired streambanks where
necessary.
4
12. Fill and compact behind boulders. Cover with topsoil, install erosion control mat, and seed.
Permanent erosion control mats will be constructed offiber or a coin fiber mixture fabric
for maximum erosion protection, vegetation establishment assistance, and for minimal
impact on wildlife.
13. 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 ofproperty 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 coir logs, large woody material, and natural fiber erosion control mats will be
used for streambank stabilization.
Once site construction has ceased, the banks of the stabilized channel will be seeded with a
native floodplain seed mix and the high stress areas with a slope of 2:1 or greater 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 15-20 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/grasses. All disturbed areas will be seeded with a temporary
native grass mixture immediately following completion of the work in those areas. Straw
mulch and tall fescue will not be used in riparian areas.
3. When possible sod will be taken from adjacent 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 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.

this work both written and verbal instructions of all impact avoidance statements provided below.
All heavy equipment will be kept out of 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 of the stream channel. Temporary gr ass cover shall be planted on all bare soil
within 5 days of ground 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 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.
