Re: Submittal of PCN Application for a Nationwide Permit 27, 401 Certification and
Neuse Riparian Buffer Approval for the proposed Meadow Creek Stream
Restoration and Bridge Re-location.
S&EC Project No. 8508.D1
Dear Ms. Burdette and Mr. Penrose,
Enclosed is the mitigation plan pertaining to the proposed relocation/restoration of
Meadow Creek and the re-location of an existing golf cart bridge located within the
Prestonwood Country Club, Cary, North Carolina. As discussed during a site meeting
that occurred on site February 19, 2004, and attended by the addressed individuals, the
project is an additional phase that will integrate with the ongoing stream and Neuse
riparian buffer restoration project that is being funded by EEP.
Prestonwood Country Club is proposing to re-locate an existing 30-foot span cart bridge
further upstream from its present location on Hatchet's Grove Tributary. The current
bridge will be replaced with an 80-foot span bridge. The upgrade to a larger span bridge
will reduce impacts to the recently constructed bankfull bench and will isolate the impact
primarily to Zone 2. The current bridge will be removed and the bankfull bench/Neuse
buffer area will be expanded and blended in with the existing bankfull bench recently
constructed immediately adjacent to its existing location. As a result of the bridge
relocation and upgrade the current channel constriction will be eliminated resulting in
additional buffer acreage.
Prestonwood is also proposing to relocated and restore Meadow Creek an unnamed
tributary of Hatchet's Grove Tributary. In its current location the creek abuts a putting
green and has been armored with rip-rap apparently to prevent migration of a developing
headcut. The mitigation plan proposes to shift 305 linear feet of stream channel to the
northwest away from the current putting green. Shifting the creek and restoring natural
stream geometry and pattern will result in approximately 311 linear feet of stream
restoration a net gain of 6 feet. The stream will join Hatchet's Grove immediately above
the bridge relocation.
I have enclosed the detailed mitigation plan, which describes the existing site and stream
conditions and the proposed stream restoration configuration. If there is any additional
information that you required please contact me at 919-280-0603 (mobile), or e-mail me
at [e-mail].

Pre-Construction Notification (PCN) Application Form
For Section 404 and/or Section 10 Nationwide, Regional and General Permits, Section 401
General Water Quality Certifications, and Riparian Buffer and Watershed Buffer Rules
This form is to be used for projects qualifying for any of the U.S. Army Corps of Engineers' (USACE)
Nationwide, Regional or General Permits as required by Section 404 of the Clean Water Act and/or
Section 10 of the Rivers and Harbors Act, and for the North Carolina Division of Water Quality's
(DWQ) associated General 401 Water Quality Certifications. This form is also to be used for any
project requiring approval under any Riparian Buffer Rules implemented by the N.C. Division of Water
Quality. This form should not be used if you are requesting an Individual 404 Permit or Individual 401
Water Quality Certification. The USACE Individual Permit application form is available online at
htlp://www. aw.usace.an-ny.mil/wetlands/Perm app.htm.
The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
USACE website at http://www.saw.usace.anny.mil/wetlands/regtour.htm, or contact one of the field
offices listed at the end of this application. The website also lists the responsible project manager for
each county in North Carolina and provides additional information regarding the identification and
regulation of wetlands and waters of the U.S.
The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been determined by the USACE.
Applicants are encouraged to visit DWQ's 401/Wetlands Unit website at
http://h2o.enr.state.nc.us/ncwetlands to read about current requirements for the 401 Water Quality
Certification Program and to determine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for some General Certifications is not required,
provided that the applicant adheres to all conditions of the GC. Applicants lacking access to the internet
should contact DWQ's Central Office in Raleigh at [phone].
Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is also required for projects occurring in any of North Carolina's twenty-five
counties that contain trout waters. In such cases, the applicant should contact the appropriate NCWRC
regional coordinator (listed by county on the last page of this application).
Page 1 of 11
CAMA Coordination - If the project occurs in any of North Carolina's twenty coastal counties (listed on
the last page of this application) the applicant should also contact the North Carolina Division of Coastal
Management (DCM) at [phone]. DCM will determine whether or not the project involves a
designated Area of Environmental Concern, in which case DCM will act as the lead permitting agency.
In such cases, DCM will require a Coastal Area Management Act (CAMA) Permit and will coordinate
the 404/401 Permits.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory. Field Office (addresses are listed at the end of this
application). Upon receipt of an application, the USACE will determine if the application is complete as
soon as possible, not to exceed 30 days. This PCN form is designed for the convenience of the applicant
to address information needs for all USACE Nationwide, Regional or General permits, as well as
information required for State authorizations, certifications, and coordination. Fully providing the
information requested on this form will result in a complete application for any of the USACE
Nationwide, Regional or General permits. To review the minimum amount of information that must be
provided for a complete PCN for each USACE Nationwide permit, see Condition 13, 65 Fed.Reg. 12893
(March 9, 2000), available at http://www.saw.usace.anny.mil/wetlands/nwpfinalFedReg.pdf.
Processing times vary by permit and begin once the application has been determined to be complete.
Please contact the appropriate regulatory field office for specific answers to permit processing periods.
401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated
as optional. Incomplete applications will be returned. Submit seven collated copies of all USACE
Permit materials to the Division of Water Quality, 401/Wetlands Unit, 1650 Mail Service Center,
Raleigh, NC, 27699-1650. If written approval is required or specifically requested for a 401
Certification, then a non-refundable application fee is required. In brief, if project impacts include less
than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to
streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is
required. A check made out to the North Carolina Division of Water Quality, with the specific name of
the project or applicant identified, should be stapled to the front of the application package. For more
information, see the DWQ website at http://h2o.ehnr.state.nc.us/ncwetlands/fees.html. The fee must be
attached with the application unless the applicant is a federal agency in which case the check may be
issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check
so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules,
the application fee does not apply, and the applicant should clearly state (in a cover letter) that only
Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to
issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application
for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the
applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional
requested information, or denial.

financial viability of the project. The applicant may attach drawings of alternative, lower-impact
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.
No permanent impacts to streams or wetlands are proposed. The project will restore
approximately 311 linear feet of perennial stream channel by incorporating a more appropriate
sinuous pattern and longitudinal profile bed form that will include riffles runs pools and
glides). The existing straightened channel length is approximately 305 linear feet and the
restoration plan will increase the stream length by approximately 6 linear feet. Portions of the
old channel that will not be connected to the restored stream will be backfilled following the
dewatering procedure
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.

Meadow Creek Stream Restoration Plan
Prepared by: Soil & Environmental Consultants, PA
1.0 Introduction
An unnamed tributary that flows into a stream locally referred to as Hatchet's Grove Tributary,
which is located within the confines Prestonwood Country Club (Prestonwood), is being
proposed to be relocated and restored in order to accommodate proposed modifications to the
existing golf course cart path bridge in such a way that will benefit the ongoing restoration work
being completed on the main stem of Hatchet's Grove. This unnamed tributary may be referred
to as Meadow Creek throughout this document. The Hatchet's Grove Stream restoration work
that is currently underway at the golf course is being funded by the Ecological Enhancement
Program (formally the Wetland Restoration Program). The proposed restoration plan and bridge
replacement will be funded and completed by Prestonwood and subsequently the stream and
additional riparian acreage created will be donated to EEP and will be protected through a
recorded conservation easement.
Prestonwood is proposing to move the location of an existing 30-foot span bridge approximately
175 feet upstream. The movement of the bridge location will accommodate a shift in the current
cart path alignment away from the left fairway and the edge of the existing mitigation
conservation easement pertaining to the restoration of the main stem of Hatchet's Grove
Tributary and adjacent Neuse buffer. The current 30-foot span bridge will be replaced with an
80-foot span bridge with an identical width. The larger span bridge will eliminate impacts to the
recently constructed bankfull bench and will limit proposed buffer impacts to Zone 2. Also after
the removal of the current 30-foot span bridge is complete, the bankfull bench will be expanded
by approximately 25 foot on either side of the restored stream channel within the former bridge
alignment increasing the acreage of Zone 1 buffer restoration by approximately 600 ftz (Figure 3).
Meadow Creek is currently in a modified and unnatural state. The current conditions of the
channel are mainly the result of historical channel modifications such as channelization and
periodic dredging, past and present day vegetation maintenance practices, and the introduction of
rip-rap placed in the channel and along the banks to armor against erosion during high flows. The
tributary currently abuts a putting green and possesses minimal native vegetation along the south
bank. The south side of the channel consists primarily of Bermuda grass. The north side has a
few sporadic large hardwood trees that flank two existing maintained sanitary sewer line
easements. The proposed relocation effort will shift the creek to the northwest away from the
manicured green into the existing conservation easement held by EEP. The channel will join
Hatchet's Grove approximately 100 feet upstream of its current alignment (Figure 3).
The majority of the stream banks are nearly vertical and exposed, with minimal vegetative cover.
As a result, the banks are actively eroding. The lower-most part of the channel has been
classified as an "F" type channel and the uppermost section classifies as an "B" type channel
utilizing the Rosgen Stream Classification System. The current channel is in an incised state,
therefore flood flows are concentrated within the channel and an active flood plain is not
accessible at the field determined bankfull elevation. As a result of the creek incision, the use of
rip-rap was more than likely placed in the creek to prevent further migration of a developing
headcut. Based on the existing conditions survey the headcut consists of a 2.5-foot drop. This
headcut indicates the transition point from the "E" to "F" type channel.
The current obviously degraded state of the channel, limited flood plain functionality due to
channel incision, existing and future erosion potential, limited native vegetation along the banks
and riparian buffer zone, and an amenable landowner to work with, presents this site as a viable
restoration project.
The restoration plan proposes to construct a stream channel that is stable and self-maintaining that
will not aggrade or degrade over time by utilizing Rosgen-based natural channel design
procedures and techniques. This will be accomplished by fulfilling the following objectives:
1) Develop a channel with the appropriate cross-sectional dimension, pattern, and
longitudinal profile utilizing the existing channel condition survey, and collected
reference reach data as a guide.
2) Improve and create bed form diversity (riffles, runs, pools, and glides).
3) Construct a flood plain (bankfull bench) that is accessible at the proposed bankfull
channel elevation (Priority I restoration) matching the bankfull elevation with the flood
plain elevation.
4) Insure channel and stream bank stabilization by integrating grade control structures, root
wads, and native vegetation, in conjunction with the eradication or modification of
current grounds maintenance practices.
5) Establish a native forested or herbaceous riparian plant community within a minimum of
30 feet, when possible, from the edge of the restored reach.
6) Integrate existing golf course uses with the proposed restoration plan providing aesthetic
and education values.
1.1 Project Site Description
The proposed restoration site is currently being utilized as a golf course facility, owned, operated
and maintained by the Prestonwood County Club. The project site is specifically located
approximately 4,000 feet southwest of the Morrisville-Carpenter Road (SR 3014)/Highway 54
Intersection and 4,000 feet east of Davis Drive (SR 1613), Morrisville, Wake county, North
Carolina (Figures 1-2). The project is entirely located within the Prestonwood Country Club
property.
The source of Meadow Creek originates in the vicinity of Morrisville Parkway and it flows
directly into Hatchet's Grove Tributary approximately 500 feet east of Prestonwood's western
property line. Hatchet's Grove tributary then flows from west to east and empties directly into
Crabtree Creek, which flows from the south to the north. The proposed restoration project
initiates approximately 200 feet east of the golf course's western-most property boundary. The
proposed restoration plan will restore an existing 305 linear feet of stream increasing the length to
311 linear feet. To eliminate the current manicured condition of the riparian buffer located
adjacent to the green, the channel will be shifted to the northwest and will join Hatchet's Grove
Tributary approximately 100 feet upstream of the current confluence and immediately upstream
of the proposed bridge relocation.
The project site currently exhibits numerous existing uses. The primary land use within the site is
as a golf course facility, which includes all of the amenities and structures required to access,
maintain, and service the area for this purpose. Structures include golf cart bridges, numerous
asphalt paths, ponds, two sanitary sewer lines, irrigation facilities, multiple stormwater outfalls,
fairway under-drain discharge pipes, and tee boxes.
1.2 Stream Survey Methodology
A field reconnaissance of the channel was performed prior to the commencement of the site
survey. The purpose of the reconnaissance is to identify the bankfull elevation utilizing existing
indicators. Typical bankfull indicators were obscured and sporadic due to active bank erosion,
slumping, grounds maintenance activities, and past channel modifications. Features that were
utilized when present included depositional features, vegetation positions, scour lines, and wrack
lines.
Soil & Environmental Consultants, PA surveyed the existing channel conditions and integrated
our data with a 1-foot topographic map of the restoration site originally completed by Withers &
Ravenel in 2002. The map was used to evaluate present landscape conditions and constraints, to
determine the final location of the proposed channel alignment, and to calculate required grading
volumes.
The channel survey included 4 cross-sections and the entire longitudinal profile of Meadow
Creek. The field data was collected utilizing a total station and subsequently the data was
processed in Microsoft Excel. The cross-section data is present in Appendix A. No cross-
sectional data was collected below the identified headcut.
1.2.1 Bankfull Verification
Cross-sectional data that was collected in the field was compared to the North Carolina Rural
Regional Curve (SRI 2000). The cross-sectional areas and the channel width of Meadow Creek
plotted above the 95% confidence interval. Channel depth fell within the 95% confidence
interval. Based on this data, the stream channel apparently was in fact dredge and as a result the
cross-sectional area was increased to almost twice that of the mean trend line as depicted on the
NC Regional Curve. The surveyed cross-sections were not utilized to generate the trend line or
the 95% confidence intervals during comparisons.
1.2.2 Stream Classification
The channel was classified utilizing the stream classification system developed by Dave Rosgen
(Rosgen 1996). This classification scheme utilizes several parameters based on field collected
data and site observation, which collectively determines the stream type. The criteria utilized to
determine stream type includes the slope, width/depth ratio, entrenchment ratio, sinuosity, and
bed materials. A summary of these channel parameters are presented in Table 1, page 8.
2.0 Existing Site Conditions
2.1 Watershed
2.1.1 General Description
The site is located in the Triassic Basin of the Piedmont physiographic region of North Carolina.
The surrounding landscape topography is characterized as hilly, with side slopes that are
generally steep to moderately sloping. The site topography is flat adjacent to the stream where
landscape modifications have not occurred; vertical fall from the project origin to the confluence
with Hatchet's Grove is just over 1 foot, resulting in a valley slope of 0.4% based on the
topographic map developed by Withers & Ravenel. This slope calculation does not include the
bankfull bench recently created adjacent to Hatchet's Grove Tributary. The wide, gently sloping,
well-defined flood plain is a Valley Type VIII as defined in Applied River Morphology (Rosgen
1996).
2.1.2 Surface Waters
The channel is located within the Neuse River Basin, USGS Hydrologic Unit 03020201 and
DWQ subbasin 030402 (USGS 1974 and DENR 1992). Meadow Creek flows to Hatchet's Grove
Tributary which subsequently flows directly into Crabtree Creek (Stream Index Number 27-33-
(1)). The North Carolina Division of Water Quality (NC DWQ) has not assigned a stream index
number to Hatchet's Grove Tributary or the unnamed tributary located within the project site.
The current State classification of the stream is Class C NSW waters (DENR 1992). Class C
waters are protected for aquatic life propagation and survival, fishing, wildlife, secondary
recreation, and agriculture. The NSW designation is a Nutrient Sensitive Waters which require
limitations on nutrient inputs. Based on the most recent USGS quadrangle the subject channel is
a I" order stream and the drainage area at the terminus of the project is approximately .23 mil
(Figure 1).
2.1.3 Soils
The project site is located in the Triassic Basin region of the North Carolina Piedmont
physiographic province. Soils present in the riparian areas adjacent to Hatchet's Grove Tributary
are characteristic of those found in alluvial landforms in the Triassic Basin. However, extensive
grading and filling associated with the golf course and installation of two individual sewer lines
has likely modified much of the naturally occurring soils within the vicinity of the restoration
project.
Chewacla soils (Aquic Fluventic Dystrochrepts) are the prevalent map unit along the channel.
Formed in fine loamy alluvial material, they are somewhat poorly drained with low natural
fertility. Wehadkee soils (Fluventic Haplaquepts) are present along the channel to a lesser extent.
These soils are also formed in fine loamy alluvial material, and are poorly drained with low
fertility. As Hatchet's Grove Branch nears Crabtree Creek, it enters a large, contiguous area of
Congaree (Typic Udifluvents) mapped immediately adjacent and parallel to Crabtree Creek.
These are also alluvial soils with low fertility frequently found on floodplains.
Other soils in the project's vicinity include Augusta (Aerie Ochraquults) and Wahee (Aerie
Ochraquults), which are often mapped on terraces. In the upland areas surrounding the project,
Mayodan (Typic Hapludults) and Creedmoor (Aquic Hapludults) are the predominate soil series,
which are both closely associated with the Triassic Basin landscape.
2.1.4 Land Use
Currently, the project site is being utilized as a golf course facility and the majority of the
surrounding area located immediately adjacent to the site has been converted to housing
(apartments and single family homes), and infrastructure uses (roads, parking lots). Areas of
forest and agricultural land exist sporadically throughout the watershed, yet numerous parcels
have recently had development plans approved by the local municipalities or are under
construction. As a result of the land use conversion, impervious area has been drastically
increased to an estimated 15-20%, and is expected to nearly double in the next decade based on
current development trends in the vicinity.
2.2 Restoration Site
2.2.1 Site Description
The restoration site consists of a historically modified (re-aligned, channelized, and dredged)
stream channel as interpreted from aerial photography supplied by the Wake County Natural
Resources Conservation Service. Photographs observed during the file search included years
1949, 1954, 1965, 1971, 1988, and 1993. Based on photographic interpretation, the site has been
historically utilized for agricultural production (row crops) from 1949 to the early 1990's. More
than likely, the site has probably been farmed since the Civil War. As a result of this past use, the
natural plant communities, topography, and hydrologic conditions have been altered or in some
cases obliterated. Since the early 1990's, land use in the vicinity has been progressively converted
to residential and commercial land uses.
Although the site use has been converted and subsequently stabilized due to the termination of
tillage, grounds maintenance adjacent to the channel has continued and is likely more aggressive
than it was in the past. Vegetation along the channel is continuously cut down to the edge of the
water in order to provide fairway visibility and clearance required for unrestricted play. The
maintenance practices combined with increased stormwater discharge resulting from the
increased imperviousness within the watershed has resulted in bank failure and channel
degradation (scour, down cutting, etc.). Previous historic alteration such has straightening and
dredging the channel has increased channel width and cross-section area, slope, stream power,
and confined flood flows which has perpetuated the channel degradation process.
2.2.2 Plant Communities
Meadow Creek is sporadically forested from the property boundary to the confluence with
Hatchet's Grove. The majority of the riparian area along Meadow Creek is located within 50 feet
of sewer line rights-of-way, mowed private property, or adjacent to manicured putting greens
vegetated with Bermuda grass (Cynodon dactylon). The existing riparian community, consists
primarily of bottomland hardwood forest species, including sycamore (Platanus occidentialis),
sweetgum (Liquidambar styraciua), red maple (Acer rubrum), and river birch (Betula nigra). In
higher areas along the channels there are small stands of loblolly pine. The shrub stratum
generally consists of smaller individuals of canopy species, as well as sourwood (Oxydenrum
arboretum), various Viburnum species, blackberry (Rubus spp.), and privet (Ligustrum sinense).
Japanese honeysuckle (Lonicera japonica) and greenbrier (Smilax rotundifolia) are particularly
vigorous and widespread in the forested riparian area, often blanketing the open forest floor.
Virginia creeper (Parthenocissus quinquefolia), poison ivy (Toxicodendron radicans) and
trumpet creeper (Campsis radicans) are present as well. Herbaceous cover primarily present
within the sewer line easements were observed to be primarily Nepal grass (Microstegium
vimineum) and to a lesser extent common wetland herbs such as Carex spp. and Juncus spp.
3.0 Reference Reaches
The reference reach described below was utilized as an aid in the design process of the proposed
Hatchet's Grove Tributary restoration plan not as a template. These channels were chosen
because of the similarities that are evident when compared to the project stream. For instance, the
reference reach and Meadow Creek are located in a wide flat alluvial valley (Valley Type VIII),
classify as E type channels, possess fine grained channel substrate, and have low gradient channel
slopes (<1%).
3.1 Sal's Branch
Sal's Branch is located approximately 1.5 miles south east of the Highway 70/540 interchange in
Umstead State Park, Raleigh, Wake County, North Carolina. Based on the Southeast Durham
7.5-minute topographic quadrangle Sal's Branch is a I' order stream and the reference survey
was collected at a point at which the drainage area was calculated to be approximately 0.35 mil.
The headwaters of the stream originate at Highway 70; which is predominately characterized as
commercial. As the creek flows onto Park property the watershed becomes forested with the
exception of an access road and buildings utilized to service the needs of the park and its patrons.
Stream data was collected in July of 2001. Information gathered included pattern and
longitudinal profile, cross-sectional area, slope, and pebble count data. Based on the data
collected, Sal's Branch was determined to be an E4 channel type when utilizing the Rosgen
Stream Classification System. The channel was determined to have a bankfull cross-sectional
area of 13.8 square feet, a width of 10.2 feet, and a mean depth of 1.3 feet.
The channel is located in a Valley Type VIII, which is characterized as a wide alluvial valley with
a low slope gradient.

4.0 Stream Channel Design
4.1 Natural Channel Design
The restoration design for Meadow Creek is based on natural channel design principles and
techniques utilizing reference reach data sets and the existing channel conditions survey data.
Reference data that has been utilized to develop the restoration design for the stream channel
included the North Carolina Rural Piedmont Regional Curve (SRI 2000), Sal's Branch reference
reach data (Doll and Jelenevsky June 2001.
The proposed stream design will restore a naturally meandering E/C type stream channel to a
more appropriate location based on the current site constraints as depicted on the Plan View
(Figure 3). A bankfull bench or nested flood plain will also be constructed adjacent to channel
alignment. The resulting restored stream channel will be approximately 311 linear feet,
increasing the overall channel length by approximately 6 linear feet. This restoration is
considered to be a Priority H restoration and is being utilized in this case because the flood plain
at its current elevation is not accessible at bankfull flows. This design is distinguished as a
Priority H stream restoration since a bankfull bench (nested flood plain) will be constructed
adjacent to the proposed channel alignment and will be located at a lower elevation relative to the
historic or existing flood plain elevation. The existing and proposed morphological
characteristics are depicted in Table 1 following this page.
The restoration design will result in a riffle-pool channel profile that will be reinforced utilizing
in-stream structures. The new channel will subsequently be vegetated with transplants, bare-root
seedlings and live stakes. Channel invert sills will be installed at the head of every other
glide/riffle interface and root wads will be installed at every outside meander bend as determined
by the designer during the construction phase to ensure stabilization of the stream channel grade
and banks. Erosion control matting (coir matting), temporary seeding, and live stakes will be
utilized to reduce bank erosion immediately following completion of the channel and provide
bank stabilization.

4.1.1 Dimension
Based on the channel survey, the bankfull cross-sectional area ranged from 17.7 to 22.1 square
feet. The average bankfull cross-sectional area is 19.6 square feet. Bankfull width ranged from
16.3 feet to 21.4 feet wide and the average bankfull width is 18.4 feet. Bankfull mean depth
ranged from 1.0 to 1.1 feet deep with an average value of 1.05 feet.
The proposed design width for Hatchet's Grove is 10 feet and an average depth of 1.0 feet. The
width and depth was determined utilizing the reference reach data, the North Carolina regional
curve, and offsite existing conditions. The proposed dimensions result in an E channel type. The
depiction of the proposed cross-section is depicted on Figure 4.
4.1.2 Pattern
The current pattern of the existing project reach is essentially straight, with a measured sinuosity
of 1.0. Channel pattern will be significantly altered resulting in a substantial increase in
sinuosity. The proposed sinuosity as a result of the proposed alignment will be approximately
1.35. Meanders have been integrated throughout the length of the project reach to the maximum
extent possible based on existing site constraints and the reference reach data. The integration of
meanders into the proposed restoration design reduces overall channel slope by increasing
channel length decreasing shear stress while providing aquatic habitat diversity.
4.1.3 Bed Form
Bed form along Meadow Creek is virtually nonexistent due to various channel modification and
off-site influences. The majority of the longitudinal profile resembles a riffle/run bed with very
few pools.
The restoration design incorporates riffles, runs, pools, and glides into the longitudinal profile
providing bed form characteristics exemplified within the reference reaches. Riffles will be
located along straight segments of the channel, runs connect the riffles to the pools which are
located along the outside meander bends and glides connect the pool to the riffle. Riffles will
have a maximum depth of 1.5 feet and the pools will be substantially deeper at a maximum depth
of 2.5 feet. The proposed longitudinal profile is depicted on Figure 5 and is plotted along with
the existing channel longitudinal profile. The as-built profile may differ slightly because of
unforeseen site constraints or limitations that may be discovered during construction (i.e.
bedrock).
9
4.1.4 Riparian Buffer Zone
A riparian buffer area will be established immediately adjacent to the restored stream channel...
The riparian zone will include the entire bankfull bench (nested flood plain) and toe slope, which
will tie the surround existing grade with the proposed bankfull bench elevation. Typical width
will be approximately 10 feet on either side of the stream channel. These areas will be seeded
and planted with the appropriate native riparian vegetation and will provide channel stability and
stormwater treatment. Species will consist primarily of herbaceous vegetation, small tree and
shrubs that can withstand annual maintenance subject to the areas that fall within the utility
easements. Areas located outside of the easements will be planted with bottomland hardwood
tree species. The detailed planting plant is addressed in Section 5.0 Planting Plan.
4.2 Stream Structures
In order to provide grade control following construction of the channel, channel invert sills,
boulder cross-vanes, step-pool structures and root wads have been integrated with the design and
will be utilized to reinforce and stabilize the proposed channel. All structures will be constructed
out of natural materials typically consisting of locally quarried boulders and or native trees.
Existing natural grade control and stable channel sections will be incorporated into the channel
profile. Although, cross-vanes are depicted at each riffle/glide interface, some of the structures
may be omitted during the construction procedures due to naturally occurring site attributes (i.e.
bedrock, etc.). Typical structure layouts, which are based on Rosgen designs, are provided on
Figure 6 (Rosgen 2001).
4.2.1 Channel Sill
The Cutoff Seal structure will be use in lieu of the traditional boulder cross-vane due to the
compact dimensions of the proposed restoration plan. This structure will function primarily as
permanent grade control preventing potential channel degradation or headcutting from occurring.
The structure will be place at a minimum at every other head of riffle where the channel grade
does not vertically exceed 0.6 of a foot. If substrate conditions are considered non-cohesive in
nature a structure will be used at each head of riffle.
The structure can be composed of either wood or boulders embedded in an appropriately sized
aggregate that is reinforced with non-woven filter cloth.
4.2.2 Boulder Cross-Vane
The boulder cross-vane structure are illustrated on Figure 6. The cross-vane is an in-stream grade
control structure that concentrates stream energy toward the center of the channel and away from
the near-bank areas reducing shear stress along the banks and preventing bank erosion. This
structure serves as grade control within the bed of the channel and reduces the potential of
headcutting, creates a stable width/depth ratio, while promoting sediment transport capacity.
Since the structure will be constructed in a sandy loam material the upstream side of the structure
will be lined with a non-woven fabric and backfilled with excavated channel material and in some
cases imported stone aggregate. This is a modification required because of the potential for the
structures to "pipe" following installation due to the voids created during the installation of the
structure in fine-grained substrate. Piping may eventually lead to structure failure and potentially
catastrophic stream bed and bank erosion.
10
4.2.3 Boulder Step-Pool Structure
The boulder step-pool structure consists of several cross-vanes located in close proximity of one
another or actually stacked together to form one uniformed structure that forms a series of steps
broken up by pools. This structure will be utilized to merge Meadow Creeks designed invert with
Hatchet's Grove Tributary. The channel inverts differ by approximately 2.0 feet.
4.2.4 Root Wads
Root wads will be utilized along the outer-most sections of the meander bends as determined
during the construction process. These structures are composed of available native trees with an
appropriately sized root fan and a 6 to 8-foot long trunk section. These structures are installed
perpendicular to the side of the stream bank with the root fan exposed to the channel while the
trunk section anchors the structure in place. If required, logs can be installed immediately below
the channel invert to serve as a footer on which the root wad is positioned. The root wad
structure serves multiple purposes such as providing protection of the outer bank from potential
erosion, provides diverse aquatic habitat, shade, and a source of detritus.
11
5.0 Riparian Planting Plan
The majority of riparian zone will be located within the permanent sewer line easements, these
areas will be planted primarily with herbaceous vegetation or transplanted sod mats consisting of
native herbaceous plants and small woody plants that will not be adversely harmed by annual
mowing. Riparian zones outside of the maintained corridors will be planted with bare root
seedlings consisting of bottomland hardwood species. Native trees and shrubs that are currently
located along the current channel clearing and excavation limits will be removed with as much of
the root ball intact and transplanted adjacent to the restored creek channel or flood plain.
Immediately following the completion of the stream channel, the bare root seedlings will be
planted during the fall or early spring seasons. During the following fall, supplemental shrub and
tree species will be planted if survival rates of previously planted seedlings are below target
densities as determined in late summer (August-September). Plant species that will be utilized
within the restoration site are listed in the table below.
The restored stream channel will be planted with the appropriate channel bank species in the form
of live stakes, bare-root seedlings, and transplants consisting primarily of black willow (Salix
nigra), silky dogwood (Cornus amomum), and elderberry (Sambucus canadensis). If quantities
from on site sources are not plentiful the live stakes will be supplemented by locally identified
plant sources (i.e. existing power line ROWS, adjacent properties, etc.) or purchased from locally
reputable nurseries.
The planting plan consists of at a minimum, three of the tree species and two of the shrubs listed
below. The goal is to plant approximately 600 bare-root seedlings per acre outside of the right of
ways, with an approximate 8-foot by 8-foot spacing.

6.0 Monitoring Plan
The restoration site will be monitored by EEP as part of the overall monitoring effort associated
with the Hatchet's Grove stream restoration project. Essentially EEP will be monitoring the
project for five consecutive years or until the required success criteria has been met as determined
by NC DWQ and the U.S. Army Corps of Engineers (USACE). Monitoring activities will initiate
immediately following the completion of the stream construction in order to alleviate any
potential problems as they occur. The riparian buffer restoration will be monitored the following
growing season projected to be summer of 2005.
Parameters that will be included in the annual stream monitoring to ensure the success of the
restoration activities will include stream channel surveys (longitudinal and cross-sectional
profiles), pebble counts, photographs, plant density, diversity and survival inventories, and
benthos sampling.
Following the submittal of the monitoring reports to the appropriate agency representatives, the
recipients of the report will be contacted for the purpose of discussing the monitoring data,
required success criteria and whether or not the site is functioning as expected. If the site is not
functioning as expected a site visit will be scheduled with the review agencies so that a
remediation plan can be created and implemented. The remediation plans, if required, will
directly reflect the requested alterations suggested by the regulatory agencies.
6.1 Stream Channel
Stream channel stability will be monitored by 1 nested set of permanent cross-sections located at
the mid point of the alignment. The cross-sections will comprise of a nested riffle and pool
segment. Each cross-section will be permanently monumented for future identity and survey.
The permanent cross-sections will also be utilized as photographic points. Cross-section
locations to be monitored will be established immediately following construction during the
completion of the "as built" survey. The "as built" report will include the constructed stream
channel dimension, pattern, and longitudinal profile. This data will be utilized as a baseline to
compare future monitoring surveys and subsequently to determine channel stability and
transition. Other stream channel measurements that will be completed during the annual
monitoring exercised will include pebble counts, stream pattern data, and stream side plant
conditions. Annual inspection of in-stream structures will also occur to insure channel stability.
Stream channel monitoring surveys will be completed annually for five consecutive years,
starting 1 year after the completion of the project.
6.2 Riparian Buffer
Vegetation within the restored riparian buffer will be monitored for five consecutive years.
Linear transects will be permanently established following completion of the planting phase and
start and end points will be permanently monumented and surveyed. The plant species, density,
survival rates, and the cause of mortality if identifiable will be recorded along each transect.
Vegetation plots will be sampled annually and reported on. every other year along with the
channel survey. The primary focus of the vegetative monitoring will be solely on the tree and
shrub stratum, although herbaceous species encountered may also be recorded. The target density
for the riparian buffer is to establish a minimum of 320 native trees species or shrubs per acre at
the end of the 5-year monitoring period. Vegetation monitoring will occur between August and
October. Riparian areas within current rights-of-way will be monitored based on percent cover.
