Re: Stream Stabilization Plan - CWMTF Agreement No. 199813-017, Grants Creek,
Salisbury, Rowan County, NC
Dear Mr. Dorney,
Enclosed is a courtesy copy of supporting data and a brief description of the action plan
for the stabilization of a large scour hole developed from hurricane Isabel flood debris
within the channel of Grants Creek near Salisbury, North Carolina. This action plan is
being developed to satisfy water quality improvement objectives for Clean Water
Management Trust Fund (CWMTF) Agreement No. 199813-017. Specifically, this plan
will stabilize an approximately 250+ if stream reach along Grants Creek, reducing stream
bank erosion, stabilizing the dimension, pattern, and profile of the stream, and improving
stream habitat along the creek corridor.
This plan is being submitted as part of the application for a Nation Wide Permit (NWP
27) to conduct stream work within the channel of Grants Creek. Since this project is not
required for mitigation and is solely for the purpose of improving water quality through
the use of state grant funds, it is our understanding that only the NWP is necessary for
construction. Recent conversation (6/28/04) with Ms. Debbie Edwards (NCDWQ) as
well as 401 certification language (GC 3399) indicates the state only suggests submitting
a courtesy notification that this stream work will be conducted according to design.
Please let us know if you would like additional information concerning this project.
We look forward to seeing the successful completion of this stream stabilization project.
If you have any comments or questions about this courtesy submittal, please contact us at
your earliest convenience.

Re: Stream Stabilization Plan - CWMTF Agreement No. 199813-017, Grants Creek,
Salisbury, Rowan County, NC
Dear Ms. Jones,
Enclosed is supporting data and a brief description of the action plan for the stabilization
of a large scour hole developed from hurricane Isabel flood debris within the channel of
Grants Creek near Salisbury, North Carolina. As discussed, this action plan is being
developed to satisfy water quality improvement objectives for Clean Water Management
Trust Fund (CWMTF) Agreement No. 199813-017. Specifically, this plan will stabilize
an approximately 250+ if stream reach along Grants Creek, reducing stream bank erosion,
stabilizing the dimension, pattern, and profile of the stream, and improving stream habitat
along the creek corridor.
This plan is being submitted as part of the application for a Nation Wide Permit (NWP
27) to conduct stream work within the channel of Grants Creek. Since this project is not
required for mitigation and is solely for the purpose of improving water quality through
the use of state grant funds, it is our understanding that only the NWP is necessary for
construction. Recent conversation (6/28/04) with Ms. Debbie Edwards (NCDWQ) as
well as 401 certification language (GC 3399) indicates the state only suggests submitting
a courtesy notification that this stream work will be conducted according to design.
The enclosed stream data includes existing condition information on the proposed
stabilization reach, existing condition information on other reaches in the vicinity along
Grants Creek, and proposed channel data and plan details. Proposed channel data is
subject to modification during construction and implementation following design
approval to ensure the successful completion and long-term sustainability of the
stream work. Stream work will include bank stabilization, filling in portions of the
scour pool hole, installation of stream structures (root-wad j-hook combination and/or
rock vane, or sill), and the creation of bankfull benches within highly eroded areas.
In addition, a 50 foot (minimum) buffer will be placed on the stabilization project to
protect the area and the entire project will be placed in a conservation easement. This
easement will either be held by the Catawba College, or The Land Trust for Central
North Carolina.
Also enclosed with this submittal and permit application are 1-foot topographic survey,
proposed channel data with CAD site plan, typical cross sections (existing and proposed),
stream structure details, vegetative planting and monitoring guidelines, and stream
stabilization monitoring guidelines. Included with the stream work plan will be details
outlining the removal of invasive and competing species within the project area to
include but not limited to Ligustrum sinense (Chinese privet). Although not required,
monitoring for this project is suggested according to guidelines set forth by water quality
regulatory agencies.
We look forward to working with you in seeing the successful completion of this stream
stabilization project with the issuance of the 404 (NWP 27) permit. If you have any
comments or questions about this submittal, please contact us at your earliest
convenience.

site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The stabilization design and construction plan (i.e. construction entrances) have been
carefully developed to minimize disturbances on the stream banks and in the stream channel. All
construction activity will occur during low flow conditions and disturbed soil areas will be
reve etg ated promptly following construction. No permanent impacts are proposed. The project
will repair approximately 250 linear feet of highly eroded stream channel caused by a debris
blockage located within the channel.
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.

Introduction
Soil, Water, & Environment Group, LLC (SWE), in coordination with Clean Water
Management Trust Fund (CWMTF), Yadkin Pee Dee River Basin Association
(YPDRBA), Catawba College, and the City of Salisbury propose to stabilize a large scour
hole developed from hurricane Isabel flood debris within the channel of Grants Creek
near Salisbury, North Carolina. This stream work plan is being developed to satisfy
water quality improvement objectives for Clean Water Management Trust Fund
(CWMTF) Agreement No. 1998B-017. Specifically, this plan will stabilize an
approximately 250+ if of stream reach along Grants Creek, reducing stream bank erosion,
stabilizing the dimension, pattern, and profile of the stream, and improving stream habitat
along the creek corridor.
The impacted stream reach flows within Grants Creek and eventually into the Yadkin
River as part of the Yadkin River Basin (Figure 1). State and Federal permits have been
applied for and this Final Plan will meet the conditions of the 404/401 permits.
Stream work will include bank stabilization, filling in portions of the scour pool hole,
installation of stream structures (root-wad -j-hook combination and/or rock vane, or sill),
and the creation of bankfull benches within highly eroded areas.
Goals and Objectives
The goal of this project is to provide a natural channel design for the stabilization of 250+
If of impacted stream channel to meet water quality improvement objectives for Clean
Water Management Trust Fund (CWMTF) Agreement No. 199813-017. Other objectives
of the project include: 1.) providing a stable stream channel that neither aggrades nor
degrades while maintaining its dimension, pattern, and profile with the capacity to
transport the watershed's water and sediment load., 2.) Improve aquatic habitat with the
use of natural material stabilization structures and in-stream grade control structures such
as j-hooks, and root wads., 3.) Enhance and protect a riparian corridor around the
proposed design reach on the subject properties, and 4.) Provide an educational
opportunity for Catawba College Science Department and the general public to learn
about the natural environment and the science and goals of stream
stabilization/restoration.
Project Description/Existing Conditions
The Grants Creek Stream Stabilization project site is located west of Old Mocksville
Ave., adjacent to Catawba College Ecological Preserve, and northeast of the City of
Salisbury along Grants Creek, Rowan County, NC. The impacted reach is in a state of
instability and departure from storm debris blockages following hurricane Isabel in 2003.
Also, past agricultural activities and past dredging and channelization activities have
added to the instabilities of Grants Creek. The drainage area of the proposed stream
1
stabilization project is approximately 60 mil. The stream washed out a large section-of _
stream bank, created a diversion channel, and scoured out a large pool behind a?debris
blockage and leftover trees from the stream banks. High shear stresses are occurring, on
vertical banks resulting in bank failure, erosion, pool and riffle aggradation, and loss of
habitat. The stream is in a state of evolution most likely starting from an E or C channel, _
evolving to an F and then to a G according to the Rosgen stream classification
methodologies (Rosgen, 1996). Bankfull benches are starting to form inside the G
channel as the stream evolves back to a C and eventually an E stream type. _
The reference reach information is located upstream and downstream of the impacted
reach. Existing bankfull indicators were utilized to propose design cross sectional areas
and bankfull bench elevations. Cross section data and other morphological
characteristics indicated the reference reach conditions for design were within limits of
regional curve data provided by the North Carolina Stream Restoration Institute (NCSRI)
for the rural piedmont. -
Topograuhv?an?d vegetation "communities in the watershed consist of expansive alluvial
bottomland hardwood forest along streams and riverine wetlands extending from rolling
piedmont mixed hardwood uplands. Soils in the restoration area consist of sandy loam
alluvial soils deposited from nearby waterbodies. Soils within the design reach most
resemble Rains and Chewacla soils as described in the USDA - NRCS Soil Survey for
Rowan county. -
Detailed Site Plans
The proposed design and stream work are included in the Appendix of this report with
data for the impacted, reference, and proposed design reaches. The design reach will be a
C/E4 stream type with Wbkf = 111 ft, dbkf = 5.2 ft, Abkf = 586 ft2, W/d = 21 ft,
dmaxbkf 11.0 (See Appendix - Stream Work Data (Existing/Proposed)). Regional
curves for the piedmont of NC developed by NCSRI were utilized in the proposed
design.
Restoration Techniques
Dimension
The proposed design reach will decrease the Wbkf and Abkf of the existing impaired
reach. A bankfull bench at least 1 bankfull width will be created along the channel to
minimize shear stress on the both right and left banks. The W/d of the design reach will
be increased from 10 to 21.2.
2
Pattern
The existing pattern developed through the creation of the scour hole from the debris
blockage will be maintained. A j-hook-root-wad stream structure will be utilized to
maintain this pattern and improve stream habitat. This pattern along with the proposed
bankfull bench will minimize shear stresses and dissipate stream energy.
Profile
The existing profile will be maintained with the exception of excavating some material
out of the pool and maintaining the current grade and scour pool with the proposed
stream structure. This structure will be designed and constructed appropriately to provide
stability, sediment transport/competence, and habitat.
Stream Structures
A combination of in-stream structures will be utilized to provide grade control, develop
scour pools, protect stream banks, and provide habitat. A J-hook-root-wad combination
and additional root wads will be installed in the impaired stream reach to meet the overall
objectives of the project (See Appendix - Stream Structures).
Construction
The construction sequence will consist of using excavators, bulldozers, loaders, or some
combination of the three machines to; 1.) fill in the scour hole according to the proposed
design, 2.) install root wad revetments and stream structures, 3.) slope the near vertical
stream banks to appropriate dimensions not to exceed 2:1 slopes, 4.) stabilize soil with
courier fabric and install tree cuttings, 5.) install non-woven fabric upstream of stream
structures, 6.) plant woody plant material (transplants, bare root, potted stock, cuttings)
and temporary herbaceous cover on the slopes and riparian zones within the project, 7.)
erect project/educational signage along Grants Creek and greenway right-of-way.
Monitoring Plan (Biological and Physical)
Stream Channel
A physical monitoring plan for the proposed design stream is suggested to ensure the
success of the stream stabilization project. Monitoring may include detailed channel
geomorphology data for dimension, pattern, profile, and channel materials. In addition,
photo reference points may be recorded and included with the monitoring reports.
Physical monitoring may include: 1.) Bank Erosion Pins w/Toe Pins, 2.) Permanent Cross
Sections, 3.) Scour Chains, 4.) Longitudinal Profile, and 5.)BEHI.

Lm?

Vegetation
A minimum of fifty (50) foot riparian zones will be established along the stream
stabilization reach. The vegetation zones will be enhanced through the removal and spot
herbiciding of invasive plant species such as Chinese privet (Ligustrum sinense) and the
planting of preferred native bottomland hardwood trees and understory plants. Planting
will be completed on a minimum 6x10 spacing (-726 trees/ac) to insure adequate
stocking and survival. Trees to be planted include: green ash (Fraxinus pennsylvanica),
shumard oak (Quercus shumardii), water oak (Quercus nigra), willow oak (Quercus
phellos), and sycamore (Platanus occidentalis). Understory species and other fast
growing species such as silky dogwood (Cornus amomum), black willow (Salix nigra),
button bush (Cephalanthus occidentalis), and Eastern cottonwood (Populus deltoides)
will be planted to supplement the restored vegetation community as well as provide quick
bank stabilization, habitat, and shade over the channel. Plants growing within the
impacted stream reach may also be transplanted to supplement the proposed planting
stock. Larger, potted plants may also be used to enhance the stream bank vegetation and
provide immediate coverage.
Vegetation should be monitored to ensure survival and replaced in the event of natural
disaster, disease, and insect predation. Replacement plants should be selected from the
proposed planting schedule.
Photo Points
Permanent photo locations should be used to document the success of the stream
stabilization project and provide data for reports if necessary. These locations can be
installed using rebar or PVC poles and/or natural permanent vegetation as guides for
photo orientation.
Conclusions
Overall this project meets the objectives of CWMTF grant 199813-017 for improving
water quality within Grants Creek and the Yadkin River Basin. Although this project is
small in scope, the long-term effects of reducing stream bank erosion into Grants Creek
from the existing impaired reach and improving water quality is significant. This stream
stabilization design utilizes the latest concepts in natural channel design to maintain the
dimension, pattern, and profile of the stream channel, while improving wildlife habitat,
stream bank vegetation and species diversity. In addition, this project will provide an
educational platform for students and the public for future water quality improvement
projects in the watershed.

Introduction:
The following Vegetation Establishment Plan is provided in accordance with the stabilization of
an approximate 250+ if stream reach along Grants Creek outside of Salisbury, NC by Soil,
Water, & Environment Group, LLC (SWE).
The stabilization area will require appropriate vegetation planted to provide stream bank
stabilization and wildlife habitat. It is suggested that this planting establishment be monitored
for growth and survival over a period of 3 years to ensure its success and long-term
sustainability. This plan will provide information relating to species selection, planting
methodologies including obtaining plant material, transportation, storage, installation, and
competition control. Monitoring should be conducted by establishing permanent plots within the
stabilization reach planting boundaries and recording the height, species, and number of planted
trees/shrubs. Natural regeneration should also be noted according to species and density.
Methodology (Vegetation Establishment):
To provide long-term protection to the stream stabilization project, all riparian areas and
disturbed areas from construction along the creek and within the floodpla.in should be replanted
with hardwood trees adapted to the specific site conditions. Currently, most of the bottomland
corridor is forested with open adjacent areas.
Existing open areas and proposed disturbed areas should be planted with a mixture of bottomland
hardwood trees to include but not limited to: shumard oak (Quercus shumardii), swamp chestnut
oak (Quercus michauxii), water oak (Quercus nigra), willow oak (Quercus phellos), swamp
black gum (Nyssa sylvatica var. biflora), river birch (Betula nigra), cotton wood (Populus
deltoides), and others as available.
Planting should be done by hand using 1-year-old seedlings at a minimum density of 726 trees
per acre or 6 x 10 ft. spacing or appropriate, older potted stock. Any trees lost as result of natural
mortality or flooding should be replaced with some or all of the above species as available.
Vegetation Establishment Specifications:
1.1 General
All plants shall be as called for by these Specifications. Bare root plants shall be used as
specified for all stream bank and riparian forest plant species. Bare rooted plants may be used in
lieu of container grown plants provided written approval for such use has been obtained from the
Project Manager. Grading of plants, type and minimum dimensions of containers shall conform
to the Specifications contained in the latest edition of American Standard for Nursery Stock.
Plants shall not be cut back from larger sizes to meet sizes called for on the plans including root
shearing. Botanical names referred to in the plans are taken from "Guide to Southern Trees",
Harrar and Harrar (1962, Dover Publications, Inc.), 2nd Ed. All plants delivered shall be true to
name. Each plant, or group of the same species, variety, and size of plant, shall be legibly tagged
with the name and size of the plant.
All plants shall be first-class representatives of their species. The root system shall be vigorous
and well-developed. The branch systems shall be of normal development, and free from
disfiguring knots, sun scald injuries, abrasions of the bark, dead or dry wood, broken terminal
growth, or other objectionable disfigurements. Trees shall have reasonably straight stems, and
shall be well branched and symmetrical in accordance with their natural habits of growth.
All plants shall be free from plant diseases and insect pests. All shipments of plants shall comply
with all nursery inspection and plant quarantine regulations of the states of origin and
destination, as well as with Federal regulations governing interstate movement of nursery stock.
If nursery stock from other states is used, the stock shall be accompanied by a tag or certificate
stating, in effect, that the nursery stock has been inspected and certified by an authorized official
of the state of origin as apparently free from injurious plant pests.
All plants shall be subject to inspection at any time by the Owner, Project Manager, or a party to
be named by the Owner. Any such inspection before or during planting operations, however
shall not be construed as final acceptance of the plants involved.
1.2 Bare Root Plants
Bare root plants shall have a heavy fibrous root system which has been developed by proper
cultural treatment. They shall be dug, packaged, transported, and handled in a manner that will
prevent injury to or drying out of the trunks, branches, or roots, or freezing of the roots.
1.3 Plant Stakes and Cuttings
Plant stakes and cuttings if approved for use by the Project Manager shall consist of freshly cut
live plants of select stock which has been developed by proper cultural treatment. Stakes and
cuttings shall be 3/8" to %Z" diameter and between 12 and 18 inches long. They shall be carefully
cut from mother-stock plantings. Plant materials shall be packaged, transported, and handled in
a manner that will prevent injury, drying out, or freezing.
1.4 Plant Substitution
No change in the specified plants (species, variety, size, caliper, furnish, etc.) will be made
without written approval of the Engineer. All requests by the Contractor for substitutions shall
be presented in writing and shall include a listing of the sources which have been contacted in an
attempt to secure the specified plant material. Requests for substitutions shall include botanical
name, common name, size, caliper, and furnish description of the proposed substitute.
1.5 Planting Preparation
Where bare root plants, plant stakes, and plant cuttings shall be planted in holes made by neatly
punching a hole into existing grade with a dibble bar (a heavy metal tool with a blade and a foot
pedal), hodad, or planting spade, the dimensions of the hole shall not exceed 3" in any direction.
Where larger, potted plant material is used, an appropriate hole should be dug twice the size of
the root ball for the particular plant. Back fill around the root ball should be compacted with the
heel of the foot or appropriate mechanical device to ensure adequate root coverage.
1.6 Planting Periods
The installation of plant stakes, cuttings, bare root, or container grown plants shall be performed
in mid to late winter, between December 1 and March 1 (best planting period February 1 to
March 1 for plant stakes) to allow plants to stabilize during the dormant period and set root
during the spring. After March 1, only bare root and container grown plants shall be used.
1.7 Competition Control
Herbicide shall be applied in accordance with the herbicide specifications regarding solution
mixtures and applied by a person certified in the State of North Carolina (North Carolina
Department of Agriculture and Consumer Services - NC Pesticide Board). Herbicide used
within wetland areas must comply with State and local laws governing the use of specific
herbicides in wetlands. Herbicide will be band applied (2 feet minimum width) using manual
backpack or hand pump applicators avoiding contact with the planted vegetation. Application
shall occur within 2 weeks of vegetation establishment. Herbicide should also be used for
invasive species control within the project area.
1.8 Soil Amendments
Apply lime and fertilizer according to soil tests. Fertilizer packs that most closely match soil
tests should be placed in each planting hole.
1.9 Submittals
Contractor shall submit purchase certificates (or other proof] of all species planted.
