APPROVAL of 401 Water Quality Certification
Dear Mr. Emrick:
You have our approval, in accordance with the attached conditions, to construct the Pine Valley Stream
Restoration Project in New Hanover County, as described in your application received by the Division of Water
Quality on January 4, 2001. After reviewing your application, we have determined that this fill is covered by
General Water Quality Certification Number 3256. This Certification allows you to use Nationwide Permit
Number 27 when it is issued by the U.S. Army Corps of Engineers. In addition, you should get any other federal,
state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion
Control, Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the
accompanying 404 permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change
your project, you must notify us and you may be required to send us a new application for a new certification. If
the property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby
responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed
one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to
be valid, you must follow the conditions listed in the attached certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You
must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition which
conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.U.
Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions are final and binding unless you ask
for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act.
If you have any questions, please telephone John Dorsey at 919-733-9646.

Pine Valley Stream Restoratiop Design Notes
Bankffill Verification
Bankfull identification and ;field cross-sectional surveys for the tributary of the Middle Branch of
Hewlett's Creek located on the golf course at Pine Valley re?ealed a cross-sectional area of 8.4 and
11.1 square feet for the cross-sections above the stream confluence (watershed area = 0.5 square
miles). Below the confluence, the cross-sectional area was measured at 17.3 square feet corresponding
to a watershed area of 0.8 square ,wiles. The watershed for the tributary is comprised of single family
residential (1/2 acre lots), golf course and some commercial property. Currently, a coastal regional
curve has not yet been developed for either urban or rural watersheds. The NC Stream Restoration
Institute is currently working on developing these curves. Preliminary survey indicates a smaller
bank full discharge and cross-sectional area for coastal streanl? in comparison to urban streams, with a
1-year return period for bankfull. Pine Valley points lae just bellow the Piedmont rural curve, despite its
fairly heavy level of development (approximately 30 % imperious) (see Figure la). However, it is
expected that coastal streams with their very pervious sandy ils would produce larger base flows and
smaller storm flows for the equivalent size watershed found irjthe Piedmont.

Sediment Transport Analysis
Methods: !

Shear Stress at the steepest ripple was checked using Shield' Curve. The shear stress placed on the
sediment particles is the force that entrains and moves the particles, given by;
T = y'RS
Where, i = shear stress (lb/ft )
y = Specific gravity of water (66.4 lb/ft)
R - hydraulic radius (ft)
S = riffle slope (ft/ft) ,
Hydraulic Radius equals Area (A) divided by the wetted pec?'r eter (P). Wetted perimeter (P) can be
estimated by the following equation: !
P - 2* (Dbkt) + WW
Where, P = Wetted Perimeter (? )
DW = bankfull mean d th (ft)
Wbkf - bankfull width ( ).

Conclusions:
Evaluation of Critical Shear Stress and comparison to Sheild7 Curve indicates that following
restoration; Pine Valley Stream will move course gravel in the range of 19-29 mm (see Figure 2). Pine
Valley is a sand bed stream with medium to course size grains (.25-1 mm). Therefore, this analysis
would appear to predict that the channel would suffer serious tour along the ripples during bankfull
discharge events. However, the Shear Stress equation and Shi lds curve are developed for gravel bed
rather than sand bed channels, The design was revised follow?g preliminary analysis of sediment
transport in an effort to reduce shear stress to the greatest ext nt possible. Stream length was increased
and ripple slopes were flattened as much as possible within th belt width available on the golf course.
Log Cross Vanes were added to stair step the stream back to de at the cart paths. Sinuosity was
increased to 1.3, exceeding the measured sinuosity of the refe nee reach of 1.1. In addition, rifle
i
?i

f
I
slopes were maintained below the valley slope of .7 percent. It is also worth noting that design
succeeds in reducing shear stress by more than half according to the analysis method. In addition, a 1-
year, 6-hours storm (approximately bankfull flow) produces 4 discharge of 47 cfs for the 0.8 square
mile watershed, assuming a runoff coefficient of 0.25. With abankfull area of 17 square feet below the
confluence, this would produce a velocity of 2.8 feet per second. This velocity should support adequate
sediment transport without resulting in excessive scour of the channel bottom.

Re: Stream Restoration Project
t
Dear Rob:
I
Enclosed are seven copies of plans, specifications, narrative and permit
application for a stream restoration project at tho Pine Valley Country Club. This
project Is being implemented through the cooperative efforts of the City of
Wilmington, New Hanover Tidal Creeks Board Pine Valley Country Club and
North Carolina Sea Grant. The funding comes;from the Clean Water Manage-
ment Trust Fund through a grant received by iv `w Hanover County. The project
engineer, Barbara Doll with NC Sea Grant, spo a with John Dorney about the
application fee and understands that it is waive because the project Is funded
by CWMTF.
As described in the narrative, disturbance] of wetlands Is just under 1/3 of
an acre and we are submitting an application package to Scott McClendon of the
Wilmington District USACOE for processing. The Intent of this project is to
improve this drainage way to a natural, stable tream with pattern and profile
that Is consistent with streams In coastal North Carolina. Please let me know if
you need any clarification or further Information. Ii

PINE VALLEY GOLF COURSE STREAM RESTORATION
NARRATIVE f '
Proiect Location ;
The project is located on the golf course of the Pine Valley Country Club within
the Pine Valley Subdivision. 'Specifically, the 100P-foot channel crosses holes 15,
16 and 17.
project Descr(ption
Decades of development have degraded stream$ throughout the North Carolina
Coastal Plain. Channelizatlon, loss of riparian vegetation, floodplain restrictions,
draining of wetlands and other changes in hydrology have altered the dimension,
pattern, and profile, and thereby the function and habitat of coastal streams.
Restoration and stabilization of degraded streams is a priority focus for many
federal, state and local government agencies and nonprofit groups. Natural
channel design techniques can offer long term Istabiiity for degraded streams
through the incorporation of natural stream While there are several
successful demonstrations of natural channel !design throughout the North
Carolina Piedmont and Mountains, few stream restoration projects have been
conducted in the North Carolina Coastal Plains.
New Hanover County, the City of Wilmington, ithe Cape Fear Resource and
Conservation District, the North Carolina Coope?ptive Extension Service, North
Carolina State Universlty,.NC Sea Grant and Pine Valley Country Club are working
together to plan and implement the demonstra on of natural channel design
based restoration along 800 linear feet of degraded stream running through the
Pine Valley Golf Course. This coastal stream, a 'tributary to the main stem of
Hewletts Creek, drains a 0.5 square mile watershed comprised of the golf
course; single family residential and commercial land uses. The stream has
eroded down to the elevation of the invert of a orm drain system installed in
the residential area of the watershed. As a restiit, the stream is entrenched;
meaning it can no longer rise out of Its banks a d spread out on a flood plain
during high flows. The resulting narrow, deep tre ch of water flows significantly
faster than a stream spread out across a wide fl od plain, causing even more
erosion. The stream is in the process of eroding o?tward to restore an adequate
floodplain and reach a balance between the amount of water flowing in the
channel, the amount of sediment it is transportinq? cnrough the channel, and the
changing slope and size of the channel. l

The removal of woody vegetation from the strOmside has accelerated erosion
on this stream. The resistance to erosion provided by soil depends on its
cohesiveness and texture. The sandy soils ;found at Pine Valley have low
cohesion and are comprised of particles small 'nough to be moved by relatively
low flows and velocities. Deeply rooted bark vegetation, especially woody
vegetation, both lessens the impact of rain dire0y on the soil and holds the soil
in place through the development of a root t .ork or root mat that stabilizes
and reinforces the soil on the streambank. The loss of this vegetation at Pine
Valley has reduced the resisting forces and helpdd accelerate erosion.
i
The goal of this project is to demonstrate the successful use of natural channel
design techniques to restore a degraded coasta? stream. The objectives are to
reduce the rate of erosion by restoring the stream to a natural balance or
dynamic equilibrium between the amount of winter flowing in the channel and
the amount of sediment it is transporting, aqd to improve the aquatic and
streamside habitats, The success of naturall channel design relies on the
accurate identification of bankfull channel dimension and discharge and the
Identification and analyses of a stable reference ?'`each to be used as a "blueprint"
In the restoration design, The project team has ?.each
an existing condition
survey, Identified existing bankfull channel 100 menslons, calculated existing
bankfull discharge, identified and surveyed stable reference reach, and
developed a stream restoration design to be esented to the New Hanover
County Tidal Creek Advisory Board at their June Meeting.
The proposed stream restoration design calls for the construction of a nested
channel, consisting of a narrow low flow channel within a larger bankfull channel
to improve stream efficiency and aquatic hauitiac, The area of the bankfull
channel is based on the existing condition survey while the width and depth are
based on dimensionless ratios taken from the i stable reference reach. The
floodplain will be widened to slow the water an reduce erosive forces at high
flow. Meanders will be constructed based on dimensionless ratios taken from
pattern measurements of the stable reference re ch to dissipate energy, restore
natural bed features, and improve the aestheti s of the stream. To prevent
future erosion, improve streamside habitat, and provide shade, the floodplain
and banks will be planted with a mix of nativ wetland plants, grasses, low
growing shrubs, and trees that can survive periodic topping. In stream
structures, root wads and log cross vanes, will be Installed to help prevent future
erosion in meander bends, improve aquatic habitat, and protect two concrete
cart bridges.
I
When completed, this project will provide a num?er of benefits, It will reduce
sediment and associated nutrient inputs from erosion, it will improve the habitat
and aesthetics of the stream, and It will serve as ai model for possible restoration
of other streams In the North Carolina Coastal Plain. In addition it will
01/04/2001 11:53 9195157095 NC SEp GRANT PAGE 10
demonstrate the commitment of New Hanover, County, the City of Wilmington,
the Cape Fear Resource and Conservation District, the North Carolina
Cooperative Extension Service, North Carolina 'State University, NC Sea Grant,
the Pine Valley Country Club, the NC Clean Water Management Trust Fund, and
the New Hanover County Tidal Creek Watershed Management Advisory Board to
protecting coastal water resources.
f;N CRITERA-
As a result of our discussions with the Wilmington Office of DENR, we
understand that this proposed project is required to get a land disturbance
permit from the Land Quality section because th amount of disturbance and
stockpile area exceeds one acre. Also, section 11A NCAC 2H.1000 applies for
stormwater management rules. We understand that this project would be
exempt from stormwater requirements because I? purpose Is stream restoration
and no impervious surfaces are proposed. ,
proposed Sediment Controls:
Three options were discussed with NCDENR staff ' or controlling sediment on this
project. In the order of preference specified by Staff for
those options are 1)
physical diversion of flow around work area, 2) by-pass pumping of flow around
work area and 3) in-stream sediment/stifling basin at the downstream end of the
project.
The first option of diversion has not been selected! for two reasons, cost and golf
course operation. The additional cost associated with piping or channeling the
flow around the work area and the replacement ?,p °nrmuda sod for the golf
fairways and greens would likely make the project! unfeasible,
The second and third options are proposed to be gsed on the project. The by-
pass pumping will be done from the upstream end'of the project at the end of an
existing 60-inch storm drain. Hoses will carry watdr to the downstream end of
the project. The in-stream-stilling basin is being p?oposed as a secondary
measure for protection of exposed areas during normal rain events. We
recognize that the basin is not adequate for the dr lnage area but Instead are
proposing a size practical for this project.
As specified, the contractor will only be allowed to kve 300 linear feet of the
stream corridor fully excavated and exposed at a time. Once the exposed areas
have been seeded and either mulched or covered v Ith biodegradable erosion
control blankets, the contractor can expose and ex avate further down the
channel. Generally, the floodplain bench will be seeded and mulched for
stabilization since this area will essentially be grade flat. The slopes from the
I
01/04/2001 11:53 9195157095 NC SE? GRANT .,PA9E 11
floodplain bench down to the water and up to the existing grades will be seeded
and stabilized with the erosion control blankets. i Theseed mix is specified in-the
contract documents.
I
A vegetation plan has also been prepared that outlines vegetation types, ranging
from grasses up to trees. The plants selected arj native to the area. The
planting will follow the stabilization activities Iist?d above.
MEAN HIGH WATER:
Not applicable
WETLANDS-
This project will have minimal wetlands impact. Wetlands are located only at the
bottom of the existing ditches. 'Less than one thihi of an Acre will be affected. A
letter requesting a General Permit will be submitted to the U S Corps of
Engineers with a copy forwarded to the Wilmingtdn DENR Office.
