Dear NC DWR,
This letter is to request Section 401 Water Quality Certification from the North Carolina
Division of Water Quality for U.S. Forest Service project: Buck Creek Stream Restoration
Proiect. Located on the Nantahala National Forest, Nantahala Ranger District in Macon County,
North Carolina, this project is situated on Buck Creek and Little Buck Creek, in the Little
Tennessee River Basin.
The Forest Service is proposing to reduce in- channel erosion and sedimentation within Buck
Creek and Little Buck Creek (Macon County) by stabilizing eroding stream banks. A trackhoe
will be utilized to restore natural contours (dimension, pattern and profile) of Buck Creek, Little
Buck Creek, and one unnamed tributary of Buck Creek. Excavated soil will be relocated on site
to a stable location and native vegetation will be reestablished. Best management practices to
prevent nonpoint- source water pollution will be utilized to protect water quality throughout the
duration of the project. Approximately 184 feet of stream restoration would be required in Buck
Creek and 150 feet in an unnamed tributary, and approximately 60 feet of stream restoration
would be required in Little Buck Creek; a total of 394 feet of stream channel. Natural channel
design concepts would be implemented to design channel dimension, pattern and profile using
reference reach data from the up and down stream reaches.
The following stream work is proposed:
Site 1:
A. Restore natural drainage at an old road crossing. Reestablish natural dimensions of the
gulied tributary. Implement erosion control measures, including native plants, mulch, and
place coir matting on stream banks. Plant native trees and shrubs for long -term
stabilization along the stream channel with species beneficial to wildlife.
B. Remove existing undersized stream crossings on the tributary and construct a natural
bottom ford to provide aquatic passage while still allowing mowing access to the wildlife
field.
C. Stabilize 54 feet of stream bank on Buck Creek to a 2:1 slope and place seed, mulch and
coir matting on the bank.
Site 2: Construct a log vane in Buck Creek to reduce erosion of right bank and improve pool
habitat.
Site 3: Construct a log vane and a bankfull bench in Little Buck Creek to reduce erosion of right
bank.

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
Site 1. One old woods road contains a non - functional wooden culvert. A nearby wildlife field contains a small
unnamed tributary of Buck Creek. The stream banks are steep and eroding into the tributary and into Buck
Creek. In addition to the tributary, a section of Buck Creek channel bank in the wildlife opening is eroding
where fill material was placed historically.
Site 2. A section of Buck Creek is experiencing high stream bank erosion adjacent to a planted white pine
stand. The stream channel has widened and has created mid- channel depositional bars.
Site 3. A section of stream bank along Little Buck Creek has sloughed off into the creek. This area continues
to erode into the stream.
3b. List the total estimated acreage of all existing wetlands on the property:
0 acre of wetlands.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Approximately 184 feet of stream restoration would be required in Buck Creek and 150 feet in an
unnamed tributary to Buck Creek, and approximately 60 feet of stream restoration would be required in
Little Buck Creek; a total of 394 feet of stream channel.
3d. Explain the purpose of the proposed project:
The goals and objectives of this project are to improve the health of the stream ecosystem by improving
channel stability and habitat quality, along with improving riparian and streamside vegetation conditions.
This will be accomplished with the construction of instream structures using trees found on site fashioned to
protect eroded stream banks and create high quality aquatic habitat features. The desired condition is to have
high quality riparian areas and aquatic habitat features that maintain hydrologic function, enhance stream
stability, and minimize erosion. The proposed action is needed at this time, at these locations, because taking
no action would lead to further erosion and sedimentation which, in turn, would cause further damage to
aquatic habitat and the maintenance of designated uses.

3e. Describe the overall project in detail, including the type of equipment to be used:
A trackhoe will be utilized to restore natural contours (dimension, pattern and profile) of Buck Creek, Little
Buck Creek, and one unnamed tributary of Buck Creek. Excavated soil will be relocated on site to a stable
location and native vegetation will be reestablished. Best management practices to prevent nonpoint- source
water pollution will be utilized to protect water quality throughout the duration of the project. Approximately
184 feet of stream restoration would be required in Buck Creek and 150 feet in an unnamed tributary, and
approximately 60 feet of stream restoration would be required in Little Buck Creek; a total of 394 feet of
stream channel. Natural channel design concepts would be implemented to design channel dimension, pattern
and profile using reference reach data from the up and down stream reach. See "Project Description" for
details.
The following stream work is proposed:
Site 1:
Tributary to Buck Creek:
1. Restore drainage at the old road crossing.
2. Lay back eroding bank to a 2:1 slope, minimum, along a 120 feet channel section, maintaining
existing trees on bank.
3. Implement erosion control measures, including native seed, straw mulch, and coir matting on stream
banks.
4. Plant trees and shrubs for long -term stabilization along the 170' section of channel using shrub species
beneficial to wildlife.
5. Remove existing crossings and construct a ford for mowing access.
Buck Creek:
Lay back about 54 feet of right bank of Buck Creek to a 2:1 slope to reduce erosion.
Road Access:
Waterbar lower 300 feet of the road accessing the site.
Site 2:
Site 3:
Construct a log vane in Buck Creek to reduce erosion of right bank and improve pool habitat.
Construct a log vane and a bankfull bench in Little Buck Creek to reduce erosion of the right bank.
All exposed soil would be seeded, mulched, and planted with live stakes and/or potted native vegetation.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Temporarily increases in turbidity are likely from the work during construction. Potential adverse impacts would be
avoided by minimizing excessive excavation and adhering to the State turbidity standard. Stream work is expected to be
completed over a two week period.
b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
A. Minimize the area and degree of soil disturbance that reduces infiltration capacity and permeability, and destroys protective
forest floor and ground cover.
B. All hazardous materials will be stored outside of flood -prone areas and surrounded with sediment fence to reduce the risk of
materials reaching the river.
C. Work activities would not be scheduled on rainy days.
D. Heavy Equipment Operation.
1. All equipment shall be cleaned before entering the project area and stream, so as to reduce the risk of fine grained
sediment and oils and grease from entering the stream. This would also reduce the risk of invasive weed spread
onto the Forest.
2. Do not operate on wet soils when they are most susceptible to damage and erosion.
3. Operate heavy equipment on slopes less than 12 percent so as to reduce the risk of soil erosion. Avoid operating
heavy equipment on over - hanging stream banks.
4. Move large woody debris in a manner that minimizes disturbance of the forest floor, exposure of mineral soil, or
degradation of stream bank stability.
E. Install sediment fence to trap potential sediment. Stabilize any disturbed area at the end of each workday.
F. Re- vegetate exposed soils as soon as possible to take advantage of the loose soil conditions for seeding.
1. Exposed soil will be covered with straw mulch or erosion control matting at the end of the project. Matting will be
secured in place with stakes and live stakes where conditions allow.
2. Temporary seeding will occur on all bare soil within five days of ground disturbing activities to provide long -term
erosion control.
3. Stabilize channel banks with a native seed mix as work is completed.
G. Do not move sediment trap devices until the vegetation in the disturbed areas has been established.
H. During on -going operations inspect the site frequently; inspect occasionally during inactive periods.
1. Check for potentially damaging or failing situations that may cause unacceptable water quality impacts.
2. Correct failing situations as soon as practical.
I. Conduct visual inspections of Buck Creek, Little Buck Creek, and the tributary while the work is being conducted to maintain
acceptable turbidity levels.
Use a skilled heavy equipment operator, trained in stream restoration and construction of in- stream structures. Instruct the
operator to minimize disturbance to the streambed.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for

Decision and Rationale
Decision
Based upon my review of the alternatives, I have decided
to select Alternative B of the Buckwheat Environmental
Assessment (August 2012 EA). The Selected Alternative
will:
Regenerate approximately 173 acres in 11 separate
stands using a two -aged method of regeneration. In
the two -age method a new stand is regenerated while
leaving a sparse overstory of trees that creates a
second age class to the next rotation. Enough of the
mature stand is removed to ensure that enough light
reaches the forest floor to sustain growth and
development of the new stand. Approximately 20
square feet of basal area per acre is left. Den trees and
hard mast producing trees are the favored leave trees.
Logging in all units would be accomplished by using
conventional ground -based systems that skids the
logs on the ground to a designated landing.
Waterbar and seed skid trails, landings, and roads
with an appropriate seed mixture following
completion of logging activities. After harvesting,
conduct site preparation for natural regeneration by
chainsaw felling of residual nonmerchantable woody
vegetation. Maintain the landings and roads as
wildlife openings.
At least two growing seasons prior to harvesting
stands 8 -24, 19 -36, 19 -37, 22 -32, and 78 -37 (totaling
about 85 acres), cut individual grape and smoke vines
in these stands, then spray the cut surfaces with
tripclopyr amine herbicide mixed 50/50 in water, or
treat them with triclopyr ester /mineral oil in a
backpack streamline spray. The vine control work is
needed in order to prevent prolific growth from
existing vines immediately after units are harvested.
The objective is to reduce grapevine and smokevine
competition to newly - regenerating trees, not to
eliminate vines from the stands. In each stand,
existing grape arbors will be left, up to V2 acre per 10
acres.
After the first growing season, conduct timber stand
improvement in all the newly- regenerated stands
(about 173 acres) by controlling undesirable
reproduction on stump sprouts (stump sprout clumps
only — no single stems) of red maple, striped maple,
silverbell, sourwood, dogwood, yellow poplar, and
blackgum and individual grape and smoke vines as
needed. Accomplish this work by backpack
streamline spray application of triclopyr ester and
imazypr mixed in mineral oil.
Conduct contract slash -down work totaling 38 acres
in stands 80 -16, 80 -17, and 80 -18, removing most of
the over -story vegetation except for a few leave trees
(15 -20 square feet of residual basal area) to simulate a
two -aged regeneration harvest area. Follow the slash -
down with a hot prescribed burn to accomplish site
preparation. Plant the areas with pitch pine seedlings
on a ten foot by twelve foot spacing. Use triclopyr
herbicide, mixed in a 20% solution with mineral oil,
up to four times as needed (in the early years
subsequent to new stand establishment), to release
the new seedlings from competing faster growing
brushy vegetation and vines. This work may be
necessary to allow time for the newly- established
seedlings to outcompete faster - growing, brushy
vegetation.
Conduct slashing treatments followed by planting
northern red oak seedlings on a ten foot by twelve
foot spacing to ensure the survival of 300 oaks per
acre on eight acres in stand 18 -37. Use triclopyr
herbicide, mixed in a 20% solution with mineral oil,
up to four times as needed (in the early years
subsequent to new stand establishment), to release
the new seedlings from competing faster growing
brushy vegetation and vines. This work may be
necessary to allow time for the newly- established
seedlings to outcompete faster - growing, brushy
vegetation.

seedlings in regeneration areas depending on need

and seedling availability. Prior) to planting, conduct
pre - harvest site preparation in the selected locations
using an appropriate herbicide ( triclopyr or
glyphosate). After planting, conduct herbicide release
at the planted locations as needed in each of several
(up to five) follow -up years. The planted sites would
be evaluated by Nantahala district personnel for
seedling survival and competitive performance. While
oak planting and post - planting herbicide treatments
are not normally needed, they are approved should
the need arise.
Continue the prescribed fire program already
established for the Buster Vinson unit (114 acres) and
initiate a prescribed fire program on the Orchard unit
(231 acres). These prescribed burns are for the
purpose of wildlife habitat improvement and fuels
reduction by reducing the amount of dead fuels on
the ground and encouraging the growth of new young
grasses and forbs for a source of wildlife food. They
are low to moderate understory burns and would
consume much of the forest floor litter but not the
underlying duff.
• Spray saplings in harvest unit skid trails (postharvest)
with triclopyr 4E to lengthen the time that grasses
occupy the skid trails, which produces more golden
winged warbler habitat over time.
• Disc, burn, and apply herbicide to all existing wildlife
openings in the area that are in poor condition.
Follow this treatment with the seeding and
establishment of new grasses and forbs in an
appropriate wildlife seed mixture.
• Conduct treatments for watershed habitat
improvement at Buck Creek and one of its unnamed
tributaries.
• Restore natural hydrological function and plant
species diversity in nine areas of riparian flats along
area streams totaling 74 acres. Restore surface flow
patterns by recontouring old roadbeds. Shrubs and
some small trees would be removed by cutting with
hand - tools. Stumps of the cut vegetation would be
sprayed with glyphosate or triclopyr herbicide to
inhibit sprouting.
• Control invasive species by spraying a triclopyr or
glyphosate herbicide solution along all system
roadsides. This treatment would be applied as many
tunes as necessary.
• Conduct roadside thinning along all existing FS
system roads for approximately 15 -30 feet on each
side. This is for the purpose of increasing sunlight to
the roads and reducing the drying time of water on
the road surfaces.
Design Criteria
Design criteria are outlined in the EA (Section 1.2,
Chapter 1). In summary, the design criteria include:
Proposed actions would meet the Partial Retention
Visual Quality Objective (VQO) (LRMP Amendment
5 pages III- 79 -83) in the MA 2 and 4 parts of the
project area. Direction for the Partial Retention
VQO is for management activities to be visually
subordinate to the characteristic landscape and to
meet the VQO within two growing seasons after
treatment.
The proposal would follow standards in LRMP
Amendment 10 (USDA Forest Service, 2000 and as
revised in 2010) to minimize the risk of incidental
take and conserve habitat for the Indiana Bat. It
would comply with the terms and conditions listed in
the U.S. Fish and Wildlife Service's Biological
Opinion (B.O., April 2000). Retain as many snags and
den trees as practicable. Designate and retain living
residual trees in the vicinity of one third of all large
( >12 inches dbh) snags with exfoliating bark to
provide them with partial shade and some protection
from windthrow. Limit openings in the upper canopy
to single tree gaps within 30 feet each side of
intermittent streams, with at least 75 feet distance
between openings. Leave up to ten well- formed
dogwood, serviceberry, and other soft -mast
producers per acre during site preparation.
• A clump of trees would be left to protect the seep in
stand 8 -17.
Brushy edges of 50 -100 ft around existing wildlife
openings will be established by heavy thinning or 2-
aged regeneration depending on site conditions.
In the Buster Vinson prescribed burn, there are three
rock outcrops suitable for the green salamander, a
NFsNC forest concern species. Green salamanders
were found in one of the rock outcrops. Forest
Service records show that this area has been burned
two times in the past. One rock outcrop is located in
a drain and is very moist. All three areas will be
burned under low to moderate fire conditions and
receive a backing fire so as to retain existing shade
conditions.
• Use brush barriers, silt fence, or hay bales to prevent
visible sediment from entering streamcourses as

needed. Revegetate all exposed cut and fill slopes
within 30 days of initial disturbance. Revegetate
and /or mulch disturbed soil at stream crossings the
same day. Restrict operations to periods of dry
weather. Comply with the forest practices guidelines
and standards in the North Carolina Forest Practices
Guidelines Related to Water Quality (BMPs).
Apply herbicides according to labeling and site -
specific analysis; all formulations and additives must
be registered with EPA and approved for Forest
Service use. Use application rates at or below those
listed as typical rates in the Record of Decision for
the Final Environmental Assessment on Vegetation
Management in the Appalachian Mountains (ROD,
FEIS -Veg. Mgmt.); use selective rather than
broadcast applications. Forest Service supervisors
and contract representatives must be certified
pesticide applicators. Sign treated areas in accordance
with FSH 7109.11. Application would be consistent
with USDA Forest Service herbicide risk assessments
(USDA Forest Service 2007a).
• Apply no herbicides within 100 feet of public or
domestic water sources; those not having an aquatic
label will not be applied within 30 feet of perennial or
intermittent streams. Mix herbicides at the District
work center and dispense into application equipment
on National Forest land at least 100 feet from surface
water.
In addition to the above measures, apply all standards
and guidelines for the appropriate MAs, as found in
the LRMP, as amended. Also, apply all 99 mitigating
measures found in the ROD, FEIS -Veg. Mgmt., and
incorporated in the LRMP by Amendment #2 in July
1989, as needed
Best Available Science
My decision is based on a review of the project record
that shows a thorough review of relevant scientific
information, a consideration of responsible opposing
views, and the acknowledgment of incomplete or
unavailable information, scientific uncertainty, and risk
pursuant to 40 CFR 1502.9(b), 1502.22, and 1502.24.
Rationale
The purpose and need for the proposal is disclosed in
Section 1.2, Chapter 1 and is to improve the existing
condition of the following: wildlife habitat, tree species
diversity, timber resources, forest health, watershed
conditions, recreational safety and access, and riparian
areas within the Buckwheat Project area, in accordance
with the Forest Plan goals, objectives and direction. The
proposed activities move this vicinity of the Forest
toward the desired future conditions established in the
Forest Plan. In addition, the projects in the alternative
will go towards meeting restoration goals for the
Nantahala and Pisgah National Forests (see Section 1.2.3
EA). Altefnative B best meets the purpose and need and
restoration goals as follows:
Direction in the Forest Plan reads, in part, to "Assure
a regular and sustained flow of habitats across the
Forests through space and time for diversity and
viability of plant and animal populations." The
proposed harvest activities would accomplish the
need to increase early successional habitat by
increasing the percentage of young forest. Harvest
activities will contribute to mixed ages of stands
throughout the project area.
• Silvicultural treatments will prepare and regenerate
harvested areas for the development of future stands,
and thinning and release treatments to improve tree
growth and promote development of young trees.
• Post- and pre - harvest regeneration and release
treatments will improve stand stocking and species
composition.
• Prescribed burning is needed to improve wildlife
forage, provide a more open understory and midstory
for wildlife species, and to reduce the dominance of
shade tolerant tree species in the understory and
therefore increase species diversity.
• Existing wildlife food plots and linear food strips are
needed to provide grass /forb habitats and shrub
habitats for wildlife species requiring those habitats.
The proposed activities are in accordance with Forest
Plan direction to "use vegetative management
practices, including commercial and noncommercial
timber harvest, to accomplish fish and wildlife habitat
objectives" (Forest Plan, p. III -24). Forest Plan
direction is to provide at least 0.5% of Management
Areas 2A and 4D in grass /forb openings.
• NNIS treatments along roads and areas that extend
into forest stands will contribute to restoration of
viable native plan communities.
In reaching my decision, I reviewed the purpose and need
for the project and the alternatives considered in detail in
the EA. I then carefully weighed the effects analyses of
the alternatives analyzed in detail and the public
comments received on the EA. The Buckwheat
Interdisciplinary Team (IDT) conducted field surveys,
database queries, and other localized analyses in order to
Decision Notice & Finding of No Significant Impact
4
Buckwheat
determine effects the alternatives considered in detail
could have on the area's ecology, including threatened,
endangered, and sensitive species. During their analyses,
they took a hard look at past, present, and reasonably
foreseeable future actions that could be combined with
expected effects from the Buckwheat proposal. I believe
they provided me sufficient analyses and conclusions to
make a reasoned decision. I believe the Selected
Alternative will move resources in the project area
towards the desired future condition, achieve the purpose
and need for the project, and addresses public concerns.
Other Alternatives Considered
In addition to the Selected Alternative B, I considered
two other alternatives in detail: Alternative A — No Action,
and Alternative C A comparison of these alternatives can
be found in Chapter 2 of the EA.
Alternative A - No Action
Under Alternative A, current management plans, such as
existing wildlife management, wildfire suppression,
general road maintenance, and special use authorization
operations would continue to guide management of the
project area. I did not select this alternative for several
reasons. This alternative would not have provided and
improved wildlife habitat;; used herbicides to
control /manage non - native invasive populations;
controlled /managed competing vegetation; improved
water quality and aquatic habitat; or created ESH. I
believe active management is needed to move the area
towards the Forest Plan's desired future condition.
Alternative C
Alternative C would include all of the treatments
proposed in Alternative B, with the exception of two -age
regeneration treatments in four areas: 8 -17 (19 acres), 19-
36 (24 acres), 22 -33 (13 acres), and 78 -37 (14 acres),
producing 103 acres of early successional habitat as
opposed to the 173 acres proposed under Alternative B.
While Alternative B falls short of the desired condition
for early successional habitat and grass /forb openings,
Alternative C produces even less. Accordingly, Alternative
B best meets the objectives of the Forest Plan while also
increasing age class diversity.
Public Involvement
This proposal has been discussed at public meetings aat
the Nantahala Ranger District office on October 4, 2010
and January 31, 2012. The proposal was provided the
public and other agencies for comment during scoping
that was initiated on February 16, 2012.
A formal 30-day Notice and Comment period began on
July 7, 2012, and ended on August 6, 2012. A total of
four members of the public provided written comments
on the EA.
I carefully reviewed and weighed all comments received
during the development of this decision and used them to
guide my decision. Comments are addressed in the EA
(see Response to Comments, Appendix D Chapter 5).
Finding of No Significant Impact
After considering the environmental effects described in
the EA, I have determined that these actions will not have
a significant effect on the quality of the human
environment considering the context and intensity of
impacts (40 CFR 1508.27). Thus, an environmental
impact statement will not be prepared. I base by finding
on the following:
1. My finding of no significant environmental effects is
not biased by the beneficial effects of the action
(Chapter 3).
2. There will be no significant effects on public health
and safety and implementation will be in accordance
with project design features (Section 1.2.3, Chapter 1;
Chapter 3).
3. There will be no significant effects on unique
characteristics of the area, because there are no park
lands, prime farmlands, wetlands, wild and scenic
rivers, or ecologically critical areas in the project area,
nor would it violate local law or requirements
imposed for the protection of the environment
(Chapter 3).
4. The effects on the quality of the human environment
are not likely to be highly controversial because there
is no known scientific controversy over the impacts
of the project (Chapter 3).
5. We have considerable experience with the types of
activities to be implemented. The effects analysis
shows the effects are not uncertain, and do not
involve unique or unknown risk (Chapter 3).
6. The action is not likely to establish a precedent for
future actions with significant effects, because the
project is site specific and effects are expected to
remain localized and short-term (Chapter 3).
7. The cumulative impacts are not significant (Chapter
3).
8. The action will have no effect on districts, sites,
highways, structures, or objects listed in or eligible for
listing in the National Register of Historic Places
(Section 3.10, Chapter 3). The action will also not
cause loss or destruction of significant scientific,
cultural, or historical resources (Section 3.10, Chapter
3). A heritage report was completed for this project
which found that there were no archeological sites
eligible for the National Register of Historic Places.
The report was sent to the State Historic Preservation
Office (SHPO) on June 21, 2012 and issued de facto
Decision Notice & Finding of No Significant Impact
5
Buckwheat
concurrence on July 23, 2012. The Tribal Historic
Preservation Office (THPO) concurred with the
report on July 16, 2012.
9. The June, 29, 2012, Biological Evaluation (Appendix
B, Chapter 5) concluded:
A. Implementation ofAlternative A, Alternative B, or
Alternative C of the Buckwheat Project would have no effects to
any threatened or endangered aquatic species because none occur
within the aquatic analysis areas and the effects of the proposed
actions would dissipate prior to reaching habitats suitable for
these species.
B. Implementation ofAlternative A, Alternative B, or
Alternative C of the Buckwheat Project would have no effects to
any threatened or endangered plant species because none were
located within the proposed activity areas.
C. Implementation of Alternative A, Alternative B, or
Alternative C of the Buckwheat Project is not likely to
adversely affect the Indiana bat (Myotis sodahs) because all
standards and guides for the protection of this species, as listed
in Amendment 10 of the Land and Resources Management
Plan, will be followed. The project will have no effect on any
other federally proposed or listed terrestrial animal species.
Furthermore, implementation of Alternative A, Alternative B,
orAlternative C would have no effects to any other threatened
or endangered terrestrial wildlife species because none occur
within the analysis areas.
D. The USDI Fish and Wildlife Service concurred with the
determinations of effect in a letter dated July 12, 2012.
10. The action will not violate Federal, State, or local laws
or requirements for the protection of the
environment. Applicable laws and regulations were
considered in the EA. The action is consistent with
the Nantahala and Pisgah National Forests Land and
Resource Management Plan Amendment 5.
Findings Required by Other Laws and
Regulations
My decision to implement the Selected Alternative is
consistent with the intent of the long -term goals and
objectives listed on pages III -1 and III -2 of Forest Plan
Amendment 5. The project was designed to meet land

Site #1: Site #1 is located off a spur road from FSR 4591 on a tributary to Buck Creek (GPS
point N35.127038, W083.239332). This area was likely farmed in the past and the stream was
channelized down to Buck Creek for almost 200 feet. The area is currently a maintained wildlife
field. One old woods road contains a non - functional wooden culvert. The wildlife field contains
a small unnamed tributary of Buck Creek. The stream banks are steep and eroding into the
tributary (Photo 1) and into Buck Creek (Figure 2). In addition to the tributary, a section of Buck

The goals and objectives of this project are to improve the health of the stream ecosystem by
improving channel stability and habitat quality, along with improving riparian and streamside
vegetation conditions. This will be accomplished with the construction of instream structures
using trees found on site fashioned to protect eroded stream banks and create high quality aquatic
habitat features. The desired condition is to have high quality riparian areas and aquatic habitat
features that maintain hydrologic function, enhance stream stability, and minimize erosion. The
proposed action is needed at this time, at these locations, because taking no action would lead to
further erosion and sedimentation which, in turn, would cause further damage to aquatic habitat
and the maintenance of designated uses.

Environmental Impacts & Mitigation
Construction would occur during dry weather conditions when seeps on the hillslope are mostly
inactive. Temporarily increases in turbidity would occur during excavation in the stream channel and on
the sideslope, but the amount would be minimized by diverting river current away from the work and by
the use of silt fence at the toe of the slope. Directly following excavation, erosion control measures
(transplants, coir matting, etc.) would further minimize erosion and sedimentation. Potential adverse
impacts would be avoided by minimizing excessive excavation and adhering to the State turbidity
standard. Work is expected to be completed over a four to five day period.
