4. Project Description and History
4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:*
Corner Rock Creek is a headwater tributary to Dillingham Creek in the Ivy Creek drainage, French Broad River Basin. Corner Rock Creek drains a forested landscape managed by the
US Forest Service and is classified by the state as WS-ll; Tr, HOW. A road and trail network access the drainage and the area is used heavily by recreationists. The stream channel in
this reach of Corner Rock Creek is a)periencing occasional bank erosion and is lacking large wood in the channel. Also, the Forest Service Road FSR74 is predominantly within 100
feet of the channel and a source of chronic sedimentation. The upper portion of the road experiences frequent flooding due to its low elevation relative to the channel belowthe
upstream FSR231 bridge crossing and erosion of the road (and sediment to the stream) are a continued concern. Corner Rock Creek is also eroding the toe of the road fill in several
locations along this reach.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?*
r Yes r No r Unknown
4d. Attach an 8 1/2 X 11 excerpt from the most recent version of the USGS topographic map indicating the location of the project site. (for DWR)
4e. Attach an 8 1/2 X 11 excerpt from the most recent version of the published County NRCS Soil Survey map depicting the project site. (for DWR)
4f. List the total estimated acreage of all existing wetlands on the property:
4g. List the total estimated linear feet of all existing streams on the property:
4h. Explain the purpose of the proposed project:*
This project is proposed to stabilize sources of streambank erosion and improve aquatic habitat diversity
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
Stream enhancement is proposed within the reach begin approAmately where Corner Rock Creek is crossed by the FSR231 bridge (GPS Coordinate of 35.75854 N, 82.38040 W) near
Corner Rock Picnic Area and extends downstream to the FSR74 crossing. Within this reach of Corner Rock Creek, bank stabilization and habitat improvement work is planned including:
1) Placement of large wood and boulders to form structures such as Log Vanes that are designed to redirect streamflow energy away from erodible banks and improve aquatic habitat
diversity, e.g. more pool habitat. 2) In company with several Lag Vanes, Toewood Revetment structures will be constructed against a streambank to create a bankfull/floodplain bench
and high quality pool habitat. These slopes will be sown with native seed, covered with Coir matting, and planted with woody species of native vegetation. 3) In addition to disturbance in
the stream channel there will be trees pushed over by a medium-sized trackhoe working within 100' either side of the channel to be used for in -stream structures.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
3i. Total temporary stream impacts:
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Construction would occur in the presence of streamflow, but flowwould be diverted away from the work activity where feasible. Temporarily increases
in turbidity are likely from the work, but because of the predominantly large sized channel substrate, suspended solids would be minimal in Corner
Rock Creek. Potential adverse impacts from turbidity would be avoided by minimiang excessive excavation and adhering to the State turbidity
standard. Work is expected to be completed over a two -week period.
1b. 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. Seeding will occur on all bare soil within five days of ground disturbing activities to provide long-term erosion control.
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 the stream 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

Corner Rock Creek Stream Enhancement Project
Appalachian RD, Pisgah National Forest
PROJECT DESCRIPTION
Submitted by: Brady Dodd, NFsNC Hydrologist, October 12, 2018/March, 2020
Current Condition:
Corner Rock Creek is a headwater tributary to Dillingham Creek in the Ivy Creek drainage,
French Broad River Basin (Figure 1). Corner Rock Creek drains a forested landscape managed
by the US Forest Service and is classified by the state as WS-II; Tr, HQW. A road and trail
network access the drainage and the area is used heavily by recreationists. The stream channel in
this reach of Corner Rock Creek is experiencing occasional bank erosion and is lacking large
wood in the channel. Also, the Forest Service Road FSR74 is predominantly within 100 feet of
the channel and a source of chronic sedimentation. The upper portion of the road experiences
frequent flooding due to its low elevation relative to the channel below the upstream FSR231
bridge crossing, and erosion of the road (and sediment to the stream) are a continued concern.
Corner Rock Creek is also eroding the toe of the road fill in several locations along this reach
(Figure 2).

Proposed Action:
Stream enhancement is proposed within the reach begin approximately where Corner Rock
Creek is crossed by the FSR231 bridge (GPS Coordinate of 35.75854 N, 82.38040 W) near
Corner Rock Picnic Area and extends downstream to the FSR74 crossing (Figure 1). Within this
reach of Corner Rock Creek, bank stabilization and habitat improvement work is planned
including:
1) Placement of large wood and boulders to form structures such as Log Vanes that are
designed to redirect streamflow energy away from erodible banks and improve aquatic
habitat diversity, e.g. more pool habitat. (See Appendix A for typicals and Appendix B
for project Specifications).
2) In company with several Log Vanes, Toewood Revetment structures will be constructed
against a streambank to create a bankfull/floodplain bench and high quality pool habitat.
These slopes will be sown with native seed, covered with Coir matting, and planted with
woody species of native vegetation.
3) In addition to disturbance in the stream channel there will be trees pushed over by a
medium-sized trackhoe working within 100' either side of the channel to be used for in -

Structure Stone
Description
The work covered by this section consists of furnishing, stockpiling, placing and maintaining approved
stone to be utilized to construct rock and log vanes, root wad structures, the step -pool structures,
stream crossings, sediment, and erosion control measures for use in locations as directed by the
Designer. The quantity of stone may be increased, decreased, or eliminated entirely at the direction of
the Designer. Such variations in quantity will not be considered as alterations in the details of
construction or a change in the character of the work.
Materials
Stone for "Misc. Boulder" shall consist of blasted stone or other stone approved by the Designer. All
stone shall be largely clean of fines, sound, tough, dense, resistant to the action of air and water, and
suitable in all other respects for the purpose intended.
All stone shall meet the approval of the Designer. While no specific gradation is required, the various
sizes of the stone shall be equally distributed within the required size range. The size of an individual
stone particle will be determined by measuring its long dimension.
Acceptance Criteria for Stone
REQUIRED STONE SIZES (INCHES)
Minimum Average Maximum
Boulder 30 48 60
48" x 24" x 18"
No more than 5 percent of the material furnished can be less than the minimum size specified, more
than 10 percent of the material can exceed the maximum size specified. Boulders shall be relatively flat
on either side in the same dimension, preferably the long dimension.
Construction
The Contractor shall place stone, in locations shown on the construction plans to the thickness, widths,
and lengths as shown on the construction plans or directed by the Designer. All stone shall be placed
neatly and uniformly with an even surface to form an in -stream structure or a sediment and erosion
control device or in accordance with the construction plans and special provisions, and shall meet the
approval of the Designer.
Method of Measurement
The quantity of stone required to construct the structures or sediment and erosion control measures
detailed in these special provisions will be incidental to those bid items. However, field conditions may
warrant the need for additional stone greater than the quantity specified or detailed for each bid item.
Corner Rock Creek Stream Enhancement Project
7 1 P a g e

The quantity of stone that has been incorporated into the project, as directed or approved by the
Designer, which exceeds 110% of the quantity required for each bid item will be measured by weight.
Measured by weight will require the quantity to be weighed in trucks on certified platform scales. Stone
that was previously stockpiled for other bid items will not be measured a second time for this provision.
Basis of Payment
When field conditions dictate the need for additional quantity greater than 10% of the bid item, the
quantity of stone measured as provided above, will be paid for at the contract unit price per ton for
"Misc. Boulder". Such price and payment will be full compensation for all work covered by this section,
including but not limited to furnishing, weighing, stockpiling, re -handling, placing, and maintaining the
stone and disposal of any materials not incorporated into the project if directed by the Designer.
Payment will be made under:
Misc. Boulder..............................................................................................................................TON
Log Vane
Description
This structure serves to decrease stress in the near -bank region while promoting scouring in the
downstream pool. Logs are placed at an angle to the stream bank, gradually inclining in elevation until
they are located near % bankfull elevation directly adjacent to the stream bank. Water flowing
downstream is forced over these logs towards the middle of the channel, effectively scouring out a pool
below. The quantity of log vanes may be increased, decreased, or eliminated entirely at the direction of
the designer. Such variations in quantity will not be considered as alterations in the details of
construction or a change in the character of the work.
Materials
Trees to be used for the vane shall be provided by the Forest Service from near the site. All log materials
shall be at least 10 inches in diameter. A sheet of woven geotextile fabric (4oz. or greater, 6-8 feet wide)
shall be placed the length of the vane arm on the upstream side, stapled to the top log in a manner that
they will be covered by back fill material. Back fill material shall be obtained from the stream channel

Toe-wood/Sod mat (bankfull bench)
Description
This structure serves to protect a length of stream bank by biulding a new bank with a bankfull area
where one did not exist before due to unstable conditions (See Toe-wood/Sod mat detail below). The
structure creates a large undercut bank providing an abundance of aquatic cover type habitat.
Materials
Trees and brush to be used for the structure shall be provided by the Forest Service from near the site.
Shrubs and willow shall be provided by the Forest Service from near the site. Excavated soil shall be
disposed of on site during construction. Seed, mulch, coir matting, and riparian plantings (live stakes,
potted material, etc.) shall be provided and installed by the contractor.

The channel shall be excavated to build a bench on the channel bottom on the outside of the meander
bend. Its elevation shall be well below determined low water elevation. A deep pool shall be
constructed where the new thalweg will be located, and excavated material shall be used to build the
point bar and back fill the structure. Footer logs laying parallel to the stream channel shall be placed on
the bench, then the toe -wood on top of that. Toe -wood shall consist of a mixture of sizes, but include
several large tree stems with root wads attached. Stems shall be pushed into the bank were possible.
Trees, brush, and limbs shall all be used to fill this area with woody debris, and be placed up to the low
flow elevation. Bundles of live stakes, e.g. willow, shall be placed on top of the woody debris and alluvial
backfill shall be placed on the structure (amount determined by Designer). Shrubs, excavated from
nearby, shall be placed on top of the toe -wood up to the bankfull elevation. This shrub mat will replace
the "sod mat". From the bankfull elevation the vertical slope shall be excavated to the 2:1 slope (run to
rise). Excavated soil material shall be scattered on the adjacent terrace. All slopes shall have seed,
mulch, and coir matting installed. Riparian plantings shall be installed on the slope and during the plant
dormant season, live stakes shall be installed in the bench and bank.

DECISION MEMO
CORNER ROCK CREEK STREAM ENHANCEMENT PROJECT
U.S. FOREST SERVICE
DILLINGHAM CREEK WATERSHED
APPALACHIAN RANGER DISTRICT, PISGAH NATIONAL FOREST
BUNCOMBE COUNTY, NORTH CAROLINA
BACKGROUND
The top of the stream enhancement project begins approximately where Corner Rock Creek is
crossed by the FSR231 bridge (GPS Coordinate of 35.75854 N, 82.38040 W) near Corner Rock
Picnic Area and extends downstream to the FSR74 crossing (Figure 1). The stream channel in
this reach of Corner Rock Creek is experiencing bank erosion and is lacking large wood in the
channel. Also, the FSR74 is predominantly within 100 feet of the channel and a source of both
chronic and potentially catastrophic sedimentation. The upper portion of the road experiences
frequent flooding due to its low elevation relative to the channel below the bridge crossing, and
erosion of the road (and sediment to the stream) will continue to be a concern. Additionally,
Corner Rock Creek is eroding the toe of the road fill in several locations. Also proposed is the
replacement of the existing culvert on FSR a tributary to Walker Creek. The existing culvert is
failing due to past high water damage.

DECISION
Within this reach of Corner Rock Creek, I have decided to do bank stabilization and habitat
improvement work including:
1) Stabilize eroding stream banks by pulling back banks to a stable slope and constructing a
bankfull/floodplain bench where feasible. These slopes will be covered with matting,
sown with native seed and planted with woody species of native vegetation.
2) Placement of large wood and boulders to form structures that are designed to redirect
streamflow energy away from erodible banks and improve aquatic habitat diversity, e.g.
more pool habitat.
In addition to disturbance in the stream channel there will be trees pushed over by a medium-
sized trackhoe working within 100' either side of the channel. All disturbed soil would be seeded
and mulched, and streambanks would additionally be covered with coir matting and planted with
riparian type vegetation. All work in the stream channel would occur between April 16'' and
October 14'', outside the Trout Spawning Moratorium.
Also, I have decided to replace the failing FSR 74 culvert crossing on the tributary to Walker
Creek with a properly sized structure.
This action is categorically excluded from documentation in an environmental impact statement
(EIS) or an environmental assessment (EA). The applicable category of actions is identified in
agency procedures as categorical exclusion 36 CFR 220.6(36 CFR 220.6 (e)(18) - Restoring
wetlands, streams, riparian areas or other water bodies by removing, replacing, or modifying
water control structures such as, but not limited to, dams, levees, dikes, ditches, culverts, pipes,
drainage tiles, valves, gates, and fencing, to allow waters to flow into natural channels and
floodplains and restore natural flow regimes to the extent practicable where valid existing rights
or special use authorizations are not unilaterally altered or canceled. This category of action(s)
is applicable because the project restores the stream system to allow waters to flow into natural
channels, connect to its floodplain and restore natural flow regimes.
I find that there are no extraordinary circumstances that would warrant further analysis and
documentation in an EA or EIS. I took into account resource conditions identified in agency
procedures that should be considered in determining whether extraordinary circumstances might
exist:
• Federally listed threatened or endangered species or designated critical habitat, species
proposed for Federal listing or proposed critical habitat, or Forest Service sensitive
species —
o A biological evaluation (BE) was completed December 1, 2019 that determined:
The Corner Rock Creek Project would not affect any federally proposed,
threatened, or endangered aquatic or botanical species because species and/or
— Decision Memo —
Page 2 of 5

habitat are not known to occur within the proposed activity or analysis area.
Consultation with the U.S. Fish and Wildlife Service is not required for botanical
or aquatic resources.
o This project may affect, but is not likely to adversely affect the northern long-
eared bat. Consultation with the U.S. Fish and Wildlife Service is not required for
northern long-eared bat for this project; however, the 4(d) rule requires the Forest
Service to notify the U.S. Fish and Wildlife Service of the proposed action 30
days prior to implementation.
o The Corner Rock Creek Project may impact individual northern pygmy
salamanders (Region 8 Sensitive), but it is not likely to cause a trend toward
federal listing or a loss of viability either locally or forest -wide.
o Effects to three Forest Concern butterflies (hickory hairstreak, golden -banded
skipper, and green comma) as a result of the Corner Rock Creek Project would be
a short-term reduction in larval habitat for two to five years and a corresponding
short-term increase in nectar species habitat.
• Floodplains, wetlands, or municipal watersheds — Wetlands are not present, and
floodplain function would be improved. The Dillingham Creek watershed is in the larger
municipal watershed for Barnardsville, NC. The proposed work would reduce
sedimentation to the watershed.
• Congressionally designated areas such as wilderness, wilderness study areas, or national
recreation areas — None are present.
• Inventoried roadless areas or potential wilderness areas — None are present.
• Research natural areas — None are present.
• American Indians religious or cultural sites — State Historic Preservation Office review of
the archeology assessment was completed on December 12, 2019 determining: One site
is eligible for listing in the NRHP under Criteria D, and preservation by avoidance is
required.
• Archaeological sites, or historic properties or areas — State Historic Preservation Office
review of the archeology assessment was completed on December 12, 2019 determining:
One site is eligible for listing in the NRHP under Criteria D, and preservation by
avoidance is required
A categorical exclusion is appropriate in this situation because there are no extraordinary
circumstances potentially having effects which may significantly affect the environment.
PUBLIC INVOLVEMENT
This action was originally listed as a proposal on the Pisgah National Forest Schedule of
Proposed Actions and updated periodically during the analysis. A scoping document was mailed
to members of the public on November 14, 2019, including local environmental organizations.
One comment was received November 17, 2018 in support of the project.

Dear Mr. Thornburgh:
Thank you for your letter of November 12, 2019, concerning the above -referenced project. We have
reviewed the archaeological survey report by Southeastern Archaeological Services and offer the following
comments.
Six sites were located within the project areas. For the purposes of compliance with Section 106 of the
National Historic Preservation Act, we concur that five sites (31BN1077, 31BN1077, 31CW485, 31CW486,
and 31CW487) are not eligible for listing in the National Register of Historic Places. These sites do not retain
sufficient subsurface integrity or artifact density to yield information important to history or prehistory.
We concur that 31BN1078 is eligible for listing in the National Register of Historic Places under Criteria D.
This site has the potential to yield significant information regarding the Middle and/or Late Woodland
period occupation in the Appalachian Province. Preservation by avoidance was recommended. If this site
cannot be avoided by restoration activities, mitigation against the adverse effect would be necessary. We
concur with these recommendations.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the
Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR
Part 800.
Thank you for your cooperation and consideration. If you have questions concerning the above comment,

Subject: Biological Evaluation (BE) for the Proposed Corner Rock Creek Watershed
Improvement Project, Appalachian Ranger District, Pisgah National Forest, Buncombe
County, North Carolina
We received the subject document (via email) on December 9, 2019. We have reviewed the
information presented and the following comments are provided in accordance with the
provisions of section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C.
1531-1543) (Act).
As proposed by the Appalachian Ranger District of the National Forests in North Carolina, the
Corner Rock Creek Watershed Improvement Project consists of activities to reduce
sedimentation and stabilize eroded areas, replacement of a culvert, and construction of instream
structures/stream enhancement. The stream enhancement work will begin at the FSR231
crossing and extend to the FSR74 crossing. Construction activities will consist of. 1) Re -sloping
and stabilizing eroding stream banks and constructing a bankfull/floodplain bench where
possible. Streambanks will be covered with matting, sown with native seed and planted with
woody native vegetation; and 2) Creating instream structures using large wood and boulders to
redirect streamflow away from erodible banks and improve aquatic habitat. Trees for instream
structures will be cut or pushed over by trackhoe.
According to the information you presented, the project will require the removal of trees that
could contain suitable summer roosting habitat for northern long-eared bat (*otis
septentrionalis), which is currently federally listed as a threatened species. To avoid impacts to
this species, the USFS plans to either remove the trees outside of the tree clearing moratorium of
April 15- October 15 or use trees that do not provide summer roosting habitat for northern long-
eared bats. For this reason, we concur with your determination that the Cove Creek stream

crossing project is not likely to adversely affect the northern long-eared bat. Further, we concur
with the "no effect" determination included in the BE for all other federally listed species known
to occur in Buncombe County. Therefore, the requirements under section 7(c) of the Endangered
Species Act are fulfilled. However, obligations under section 7 of the Endangered Species Act
must be reconsidered if: (1) new information reveals impacts of this identified action that may
affect listed species or critical habitat in a manner not previously considered, (2) this action is
subsequently modified in a manner that was not considered in this review, or (3) a new species is
listed or critical habitat is determined that may be affected by the identified action.
We appreciate the opportunity to provide these comments and request that you continue to keep
