This letter is to request Section 401 Water Quality Certification from the North Carolinas
Division of Water Quality for U.S. Forest Service project: Thos Creek Stream Enhancement Creek Stream Enhancement
Project. Located on the Pisgah National Forest in Caldwell County, North Carolina, this project
is situated on Thorps Creek, of the Wilson Creek watershed, Catawba River Basin.
Thorps Creek is classified by the state as an Outstanding Resource Water. This reach of stream
channel is within the Mortimer Recreation Area, and is currently adversely impacted by channel
manipulation, stream bank hardening from log crib walls and a loss in streamside vegetation
from recreation site development and foot traffic. As a result, sections of stream bank within the
reach are unstable; aquatic habitat diversity is lacking; and streamside and alluvial forests are
degraded.
This project proposes the following:
1. Reconstruct the existing `B" stream type along approximately 700 feet of channel, using
reference reach information. Where the stream has been channelized, excavate a bankfull
bench and lay back - 1,400 feet of stream bank to a 2:1 (run:rise) slope or less.
2. Construct up to seven log and/or boulder vanes and -80 feet of toe -wood structure within
the 700 feet stream reach. The instream structure below the fish barrier would create a
pool to improve passage of trout. Spacing of constructed channel features (e.g., riffles
and pools) would be determined using longitudinal and cross section data from the
upstream reference reach.
3. Implement erosion control measures, including native seed, straw mulch, coir matting on
stream banks, planting trees and shrubs, and installing split rail fence for long-term
stabilization. Replace the footbridge following the proposed stream work.
A copy of the 404 permit application has also been sent to the N.C. Wildlife Resources
Commission and U.S. Fish and Wildlife Service for review.
Enclosed are the following materials:
• Five copies of the Pre -Construction Notice (form 12-11-2008 version 1.3), application for
Caring for the Land and Serving People Printed on Recycled PapeV
404 permit (Nationwide Permit #27), with the Letter of Delegation of Authority
• Five copies of the Project Description with vicinity map and site plans for the project
• Five copies of the project Decision Memo
• A check made payable to the Division of Water Quality for $570.00 since activities
cumulatively account for more than 150 feet of stream channel.

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:
Thorps Creek is a tributary to Wilson Creek in the Catawba River Basin, and is classified by the state as an
Outstanding Resource Water. This reach of stream channel is within the Mortimer Recreation Area, and is
currently adversely impacted by channel manipulation, stream bank hardening from log crib walls and a loss
in streamside vegetation from recreation site development and foot traffic. As a result, sections of stream
bank within the reach are unstable; aquatic habitat diversity is lacking; and streamside and alluvial forests are
degraded (Project Description, Figures 2-4). The Thorps Creek drainage is 1.14 square miles in size and is
mostly forested and predominantly in federal ownership. Past management in the watershed within the last
hundred years included logging much of the timber using roads, railroads, and possibly splash dams to
transport timber downstream to local mills. Following harvest, much of the flatter terrain was used for
farming and small homesteads.
3b. List the total estimated acreage of all existing wetlands on the property:
0 acre in the project area.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Approximately 6,000 feet in the Thorps Creek drainage.
3d. Explain the purpose of the proposed project:
The goals 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. The desired condition is to have high
quality riparian areas and aquatic habitat features that maintain hydrologic function, enhance stream stability, minimize
erosion, and maintain the attributes which qualify Wilson Creek as a Wild and Scenic River, and maintain the State
classification for Thorps Creek of Class C, Trout, and Outstanding Resource Waters. 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 recreation sites.
3e. Describe the overall project in detail, including the type of equipment to be used:
This project proposes to do the following (refer to attached "Project Description" for details):
• Reconstruct the existing "B" stream type along approximately 700 feet of channel, using reference reach
information. Where the stream has been channelized, excavate a bankfull bench and lay back — 1,400 feet of
stream bank to a 2:1 (run:rise) slope or less.
• Construct up to seven log and/or boulder vanes and —80 feet of toe -wood structure within the 700 feet stream
reach. The instream structure below the fish barrier would create a pool to improve passage of trout. Spacing of
constructed channel features (e.g., riffles and pools) would be determined using longitudinal and cross section
data from upstream in the reference reach (Appendix A — Reference Reach Data).
• Implement erosion control measures, including native seed, straw mulch, coir matting on stream banks,
planting trees and shrubs, and installing split rail fence for long-term stabilization. Replace the footbridge
following the proposed stream work.
A medium sized trackhoe shall be used in the construction of this project. All disturbed area shall be seeded and
mulched. The split rail fencing would be purchased and constructed using other funding. USFS Hydrologist to be
resent during construction.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Construction would occur largely in the dry, facilitated by pumping around the work site to avoid elevated turbidity
and sediment yield to Thorps Creek. A temporarily increase in turbidity and sediment deposition downstream of the
site is possible when the stream is turned back into the new channel. The implementation of pumping around and
erosion control should minimize sediment, and stabilization of the bank should decrease erosion and sedimentation
overall. Work is expected to be completed over a one week period, depending on weather.
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 stream.
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 and boulders in a manner that minimizes disturbance of the forest floor,
exposure of mineral soil, or degradation of stream bank stability.
E. Install sediment fence or coir logs 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 pine -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 temporary seed mix of wheat, millet, or similar annual grain 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 streamflow while the work is being conducted to maintain acceptable turbidity
levels.
J. 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

Thorps Creek Stream Enhancement Project 2016
Project Description
Submitted by: Brady Dodd, NFsNC Forest Hydrologist, April 2016
PROJECT CURRENT CONDITION:
Thorps Creek is a tributary to Wilson Creek in the Catawba River Basin, and is classified by the state as
an Outstanding Resource Water. This reach of stream channel is within the Mortimer Recreation Area,
and is currently adversely impacted by channel manipulation, stream bank hardening from log crib walls
and a loss in streamside vegetation from recreation site development and foot traffic. As a result,
sections of stream bank within the reach are unstable; aquatic habitat diversity is lacking; and
streamside and alluvial forests are degraded (Project Description, Figures 2-4). The Thorps Creek
drainage is 1.14 square miles in size and is mostly forested and predominantly in federal ownership. Past
management in the watershed within the last hundred years included logging much of the timber using
roads, railroads, and possibly splash dams to transport timber downstream to local mills. Following
harvest, much of the flatter terrain was used for farming and small homesteads.

PROJECT PURPOSE & NEED:
The goals 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. The
desired condition is to have high quality riparian areas and aquatic habitat features that maintain
hydrologic function, enhance stream stability, minimize erosion, and maintain the attributes which
qualify Wilson Creek as a Wild and Scenic River, and maintain the State classification for Thorps Creek of
Class C, Trout, and Outstanding Resource Waters. 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 recreation sites.
SUMMARY OF PROPOSED WORK:
1) Reconstruct the existing "B" stream type along approximately 700 feet of channel, using
reference reach information (Appendix A — Reference Reach Data). Where the stream has been
channelized, excavate a bankfull bench and lay back — 1,400 feet of stream bank to a 2:1
(run:rise) slope.
Thorps Creek Stream Enhancement Project 2016 Page 4
2) Construct up to seven log and/or boulder vanes and —80 feet of toe -wood structure (Figure 5
and see Appendix B & C for Structure Typicals) within the 700 feet stream reach. The instream
structure below the fish barrier would create a pool to improve passage of trout. Spacing of
constructed channel features (e.g., riffles and pools) would be determined using longitudinal
and cross section data from upstream in the reference reach (Appendix A— Reference Reach
Data).
3) Implement erosion control measures, including native seed, straw mulch, coir matting on
stream banks, planting trees and shrubs, and installing split rail fence for long-term stabilization.
Replace the footbridge following the proposed stream work.
A medium sized trackhoe shall be used in the construction of this project. All disturbed area shall be
seeded and mulched. The split rail fencing would be purchased and constructed using other funding.

IN -STREAM STRUCTURES SPECIFICATIONS
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 Coarse Aggregate, No. 57 Stone, "Rip Rap -Class B", and "Boulder" shall consist of blasted stone
or other stone approved by the Designer. The stone shall be 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
CLASS REQUIRED STONE SIZES INCHES
Minimum Average Maximum
Boulder 20 36 42
48" x 24" x 24"
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
Thorps Creek Stream Enhancement Project 2016 Page 13
warrant the need for additional stone greater than the quantity specified or detailed for each bid item.
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. Coarse Aggregate, No. 57 Stone", "Misc. Rip Rap -Class B", and "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
Rock] -hook & Cross Vane
Description
Rock J -hook and Cross Vanes are primarily used for grade control. These structures serve to maintain the
integrity of the upstream riffle while promoting scouring in the downstream pool. The design shape is
roughly that of the letter "J" or "U" with the apex located on the upstream side at the foot of the riffle.
Footer boulders are placed in the channel bottom for stability. Header boulders are then placed on top
of these footer boulders. Header boulders in the middle of the channel are at approximately the same
depth as the riffle. For the J -hook, on one side of the channel, wing boulders are placed at an angle to
the stream bank, gradually inclining in elevation until they are located near the bankfull surface directly
adjacent to the stream bank. On the other side, the structure turns downstream to create the hook of
the "J", matching the slope of the wing until it goes directly toward the bank as a sill. Water flowing
downstream is forced over these boulders towards the middle and opposite side of the channel,
effectively turning flow and scouring out a pool below. Boulders placed at the apex hold back streambed
material and prevent it from washing downstream.
The quantity of Rock J -hook 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 (See Rock J -hook Vane detail below).
Materials
All materials shall meet the requirements of boulder as outlined in Special Provision "Structure Stone".
Back fill material shall be obtained from the stream channel bed, likely from the constructed pool. Large
woody debris may be incorporated into the structure as directed by the Designer.
Installation
A trench shall be dug in such a manner that the footer boulders, the hook header boulders and at least
1/3 of the wing boulders are buried beneath the bed surface elevation. Refer to the construction plans
for exact installation guide and locations of vane to be installed. An excavator, with a bucket that
Thorps Creek Stream Enhancement Project 2016 Page 14
includes a hydraulic thumb, shall be used to place boulders under the supervision of Designer. Footer
boulders shall be placed first with header boulders placed on top prior to any back filling of the trench.
Boulders shall be selected and positioned such that they butt tightly together and there are multiple
contact points between all boulders (flat smooth surfaces that fit together). Gaps between boulders
shall be filled (chinked) with a combination of class A and No. 57 size stone found on site until plugged.
In the center portion of the channel (vane invert), the header boulder shall be placed with gaps between
the rock with the top of the header boulder at an elevation designated by the Designer. The header
boulders in the side, or wing, portion shall be placed in such a manner as they slope up from bed
elevation to bankfull or below at a 2 to 7 percent slope or as shown in detail. Header and footer
boulders at both banks shall be tied in securely to the bank in such a way that eliminates the possibility
of water diverting around them. A rock sill shall be utilized to further prevent water from cutting around
the structure. The area between the stream bank and vane on the upstream side of the structure will be
backfilled with stream bed material.
Structures shall be built to the approval of the Designer. The Designer may adjust the number and
placement of structures in the field.
Basis of Payment
Payment for installation of Rock J -hook Vane shall be as outlined. This payment shall be considered full
compensation for all labor, equipment, hauling, placing, handling, sorting, fitting, materials, and
incidentals necessary to construct the rock vane.
Payment will be made under:

Toe-woad/,hod 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
hauled off the site and dumped within 5 miles by the contractor. Seed, mulch, coir matting, and riparian
plantings (live stakes, potted material, etc.) shall be provided and installed by the contractor.
Installation
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

than 1 foot deep for use on side slopes and no less than 3 feet for areas at the toe of the slope and along
the top edge of matting. Place the matting upon final grading, following seed and mulch application.
Provide a smooth soil surface free from stones, clods, or debris which will prevent the contact of the
matting with the soil. Unroll the matting starting at the bottom of the slope and apply without
stretching such that it will lie smoothly but loosely on the soil surface. Bury the top end of each piece of
matting in a narrow trench at least 6 in. (150 mm) deep and tamp firmly after staking with evenly spaced
stakes. Stake the matting according to the manufactures recommended pattern for specific product and
slope. Where one roll of matting ends and a second roll begins, install matting end -over -end with
approximately 6 inches of overlap. Stake through overlapped area using 5 stakes. Install stakes across
the matting at ends, junctions, and trenches approximately 1.3 feet apart. See the figure below for the
Erosion Control Matting Detail.

DECISION MEMO
THORPES CREEK & UPPER CREEK STREAM IMPROVEMENT
PROJECTS
U.S. FOREST SERVICE
GRANDFATHER RANGER DISTRICT
BURKE & CALDWELL COUNTIES, NC
BACKGROUND
At the Thorpes Creek project site, the stream channel is currently impacted by stream bank
hardening from log crib walls and a loss in streamside vegetation from recreation site
development and foot traffic. As a result, sections of stream bank within the reach are unstable;
aquatic habitat diversity is lacking; and streamside and alluvial forests are degraded. The Thorps
Creek drainage is 1.14 square miles in size and is mostly forested and predominantly in federal
ownership. On Upper Creek, the ford on Forest Service Road (FSR) 986 is made of concrete,
spanning the entire channel width of the channel. Therefore, when stream flow is low, water
depth is low and velocities are high over the ford, making passage of fish and other aquatic
organisms difficult or impossible. Just downstream is an old log dam used at one time to restrict
passage of fish, today it is damaged and no longer functioning and will therefore be removed.
DECISION
I have decided to implement the Upper Creek and Thorpes Creek Stream Improvement Projects
on the Grandfather Ranger District. While maintaining the concrete ford approaches on the
Upper Creek site, we will remove the center of the ford between the poured concrete seams.
Also involved will be the construction of a natural bottom ford using existing channel substrate
and imported boulders. The removal the old fish barrier will be achieved by pulling the logs out,
leaving the channel substrate stored behind it in place. The composition of substrate is a mix of
fine gravel to large cobble sizes and will benefit the channel below when it relocates during high
flows.
At the Thorpes Creek site, we will lay back approximately 700 feet of eroding stream bank to a
2:1 (rise: run) slope and replace the footbridge following the completion of proposed stream
work. The stream work includes removal of three old fish structures, construction of up to three
log and boulder vanes and two constructed riffles. The instream structure below the fish barrier
would create a pool to improve passage of trout. Once construction is completed we will
implement erosion control measures, including native seed, straw mulch, coir matting on stream
banks, planting trees and shrubs, and installing split rail fence for long-term stabilization.
— Decision Memo —
Page 1 of 4
M
USDAarm—
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 Removing, replacing or modifying water control structures to restore the
flow of waters into natural channels and floodplains 32.2 (18) a of categorical exclusion and
CFR citation as described in FSH 1909.15 Sec. 31.2)]. This category of action(s) is applicable
because this project has been designed to "restore flow into natural channels and floodplains"
that was previous manipulated into "unnatural" conditions.
I find that there are no extraordinary circumstances that would warrant further analysis and
documentation in an EA or EIS. I took into accouni 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. The biological evaluation of these proposed stream improvement projects found
that no botanical, wildlife or aquatic threatened or endangered species will be effected by
the project implementation. No designated critical habitat or Forest Service sensitive
species (botanical, wildlife or aquatic) exist. .
• Flood plains, wetlands, or municipal watersheds — The floodplains of these stream
improvement projects will improve with implementation.
• Congressionally designated areas such as wilderness, wilderness study areas, or national
recreation areas — none exist.
• Inventoried roadless areas or potential wilderness areas — None exist.
• Research natural areas — None exist.
• American Indians and Alaska Native religious or cultural sites — None exist.
• Archaeological sites, or historic properties or areas — These projects were considered an
exempt undertaking by USFS Archeologist, Scott Ashcraft, which concludes the
activities are in compliance with the programmatic Memorandum of Understanding
between the National Forest of North Carolina, North Carolina State Historic
Preservation Office (SHPO) and Tribes. As such Tribal and NC SHPO concurrence is
not necessary.
These restoration projects have been designed to have a positive impact on the long term health
and viability of the watersheds involved.
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. The Collaborative Forest
n Landscape Restoration Project (CFLRP) cooperators of the Grandfather Ranger District are also
supportive of these projects. The proposed action meets one of the primary goals of the CFLRP
— Decision Memo —
Page 2 of 4
to "Restore riparian vegetation, remove fish passage barriers, reduce sedimentation and
reconnect streams to their flood plains to benefit water quality and aquatic ecology."
The CFLRP collaborative involves many partners. State and national natural resource
management agencies involved in the project include the National Forests in North Carolina,
North Carolina Forest Service, North Carolina Wildlife Resources Commission, North Carolina
Department of Natural Resources, National Park Service, and the Fish and Wildlife Service.
Local environmental conservation organizations include Wild South, Western North Carolina
Alliance, Foothills Conservancy, Southern Area Wilderness Stewards, Land of Sky Regional
Council, Friends of Wilson Creek, and the Grandfather Mountain Stewardship Foundation.
National conservation organizations with local presence include The Nature Conservancy and
The Wilderness Society. Special interest wildlife groups include Trout Unlimited, National Wild
Turkey Federation, and Quality Deer Management Association. Special interest recreation trails
groups include the Southern Area Wilderness Stewards and the volunteer trails coordinator for
the Linville Gorge Wilderness Area. Research partners include the Southern Blue Ridge Fire
Learning Network, the Forest Service Southern Research Station, Forest Stewards, and Western
Carolina University. The local wood -products industry is represented by Appalachian Designs.
FINDINGS REQUIRED BY OTHER LAWS AND REGULATIONS
This decision is consistent with the Nantahala and Pisgah National Forest Land Management
Plan. According to direction for management area 18 (riparian resources), soil and water
management should "protect the integrity of the stream system including channel, banks and
stream bottom (LRMP III -187). This project also adheres to the Clean Water Act 33 U.S.C.
§ 1251 et seq. (1972) by "restoring watersheds and their aquatic ecosystems to provide for
healthy habitat for fish, plants and wildlife." (EPA, Office of Water Standards).
ADMINISTRATIVE REVIEW (APPEAL) OPPORTUNITIES
This decision is not subject to administrative review and appeal.
