Response to Request for Additional Information - DWQ Project No. 021823
Dear Mr. St. John:
This letter is in response to your January 30, 2003 letter to Andrew Burg requesting additional
information regarding the proposed design for the Wellingford Street Regional Water Quality
Basin Project (DWQ Project No. 021823).
Comment: Bankfull
Based on the "backwater" nature of the design stream, it is not apparent why the bankfull cross section of
the proposed channel would be much larger than that of Big Branch, which is the most similar reference
stream based on drainage area. Please explain the larger cross sectional area of the design stream.
Response: The primary factor for the increase in cross-sectional area of the design channel when
compared to the Big Branch reference reach is the channel slope. The slope of the design channel
is lower than the slope of the Big Branch reference reach area. Using the Manning's equation in
the process of developing a design cross section, a lower slope requires a larger cross sectional
area to carry the bankfull discharge given equivalency in roughness.
Please call me at [phone] if you have any questions. Thank you for your assistance.
Very truly yours,

Upper Little Sugar Creek Environmental Restoration Project
Pre-Construction Notification for Nationwide 27
CDM Project No. 19864-29162-DN.FINL
Dear Mr. Dorney:
Mecklenburg County Storm Water Services proposes to construct a system of urban retrofit
stormwater BMPs, wetlands, and stream restoration areas designed to improve the health of
Little Sugar Creek in Charlotte. The project involves the purchase of urban residential
properties and removal of existing structures from the floodplain to decrease impervious
area. Wetlands will be constructed adjacent to Little Sugar Creek, and the stream will be
restored using natural channel design techniques. Major goals of the project include
measurably decreasing pollutant loading in Little Sugar Creek, restoring stream function and
wildlife habitat, improving stormwater controls and management, creating a functional
wetland system,`. improving the aesthetics of the surrounding neighborhood, and providing
educational opportunities for schools and the community. The project is being partially
funded by the Clean Water Management Trust Fund (CWMTF).
Enclosed please find a Pre-Construction Notification Application and related design
drawings for the project. A permit for this project is requested under Nationwide Permit #27.
Please review the application and call me at [phone] if you have any questions or need
additional information about the project. Thank you for your assistance.
Very truly yours,

Response to Cownunts - DWQ Project No. 021823
CDM Project No. 1986¢29162-DN.FDM
Dear Mr. St_ John-
This letter is in response to your December 3, 2002 letter to Andrew Burg outlining your
concerns regarduag the proposed design for the Wellixf gford Street Regional Water Quality
Basin Rcoject (DWQ Froject No. 021523). Listed below are your comments and subsequent
responses to each of those comments. .Also included in this submittal is a revised Detail Street
D1, which incorporates changes resulting from your comments.
Comment # 1: Stream Restoration
Stream restoration is defined as "Stream restoration is the process of converting an unstable, altered or
degraded stream corridor, including adjacent riparian zone and floodprone areas to its natural or
referenced, stable conditions considering recent and future watershed conditions. This process also
includes restoring the geomorphic dimension, pattern and profile as well as biological and chemical
it tegrity, including transport of water and sediment produced by the stream's watershed in order to
achieve dynamic equilibrium.' Based on your submittal, there is not enough information to conclude
the stream restoration will be achieved. As such, you must "resubmit" the plants with the information
requested below.
Response #1: Additional information is enclosed for your review including a revised detail
sheet (Sheet D1) that will be included in the final drawing set.
Comment #2: In Stream Stm ores and/or Channel Blocks
The proposed cross vane and v-log drop structures should have arm slopes shnilar.to those of the log
vane profile detail. May not function properly as designed. Please see the conceptual typicals provided
in Appendix G of The Internal Technical Guide ar Stram Work in North CarolApril 2001.

Response #2: Cross vane and v-log drop axon slope range information has been added to the
.structure details on Sheet DI (enclosed)-
Comment #3: Morphological Measurements Table
please complete the Morphological Measurements Fable provided in Appendix B of the site plans must
contain the information specified on page 13 of The Internal Technical Guide for Stream Work in North
Cara lrna? April 2001.
Response #3: The morphological measurements table has been remised and is enclosed for
your review. Due to the size of the table, it has been removed from the coves sheet and added
to the permit application as A.ttachnient C.
Comment #4: Design Values and Ratios
The design values and ratios provided reflect an excessive amount of variation. This could be the result
of there being more than one stream reflected in the data. In any event, the variation in the data needs.
to be clarified.
Response #4: More than one reference reach was used for a few specific reason. First, the
project area, with a t abutary and maiazstem design channel, has a range in drainage area size.
The reference reach areas used provide a similar range is drainage area size- Second, we
wanted to use both E4 and E5 reference reach data because the project site has both sand and
gravel bed material, with a predominance of sand at this point. It is anticipated that with an
increase in defined bed features, particularly in percent riffle lerta th for the proposed design
channel as compared to the existing channel, the proposed E5 diaxnnel riffle areas will likely
coaxsen slightly over time and border on an E4/E5 system.
In most cases the design values and ratios are very siax&ar to the reference react ratios. For
many of the design values and ratios, the range in data'for the reference reaches and the
proposed channel is m minial and certainly within the range of published literature values for
E channels.
One notable dif:ferene between the proposed reach and the reference reach data is the
meander width ratio (Beltwidth/Bankftrll width). The proposed channel has been designed
to span the entire proposed floodplain in an effort to spread out-of baarik iffow throughout the
floodplain. A large component of the scope for this project is to enhance the water quality of
stbrmwafer runoff. The -proposed alignment, floodplain gzading and planting plant are
designed to meander the proposed E tunnel through a large area of emergent and forested
floodplain in an effort to retain and filter the out-of-bank flows as a means of water quality

treatment. Although the meander width ratios used for the design channel are higher than
the reference data, they are actually slightly below the average value provided in Figure 4-4 m
Applied River Morphology (Rosgen,1996). Due to lateral constraints, the beltwidth could not be
increased beyond the proposed li=ts. Thus the proposed ratio of beltwvidth to banldull
width is at the upper end of what is feasible for this site in an effort to maximize water quality
benefits.
Comment # 5: Sediment Transport Analysis
A sediment transport analysis can confirm that a stream has been property designed. A naturally
stable stream transports its bedload in equilibrium so that there is no net aggradation or degradation
over the stream reach. As such, it is necessary that the predicted sediment transport in the design
stream be demonstrated to be in equilibrium to ensure overall stability will be achieved.
Response #5:.A sedbxieat hansport analysis was conducted for Little Sugar Creek using
standard Shield's curve analysis. In the classic Shields analysis, the threshold point for
sediment movement, or critical condition, occurs when the forces of flow are exactly balanced
by the submerged weight of the particle. This relationship was expressed in terms of grain
diameter (anm) versus critical shear stress (lb/ftz) for ease in fluvial applications by Leopold,
Wolrrw, and Miller (1964), and applied here.
The critical shear stress for the proposed Little Sugar Creek channel was calculated for the
design channel geoeixy, and is given by;
= Y RS
Where,
T = shear stress (lb/ft2)
y = specific.gravity of watex (62.41 /ft3)
R = hydraulic radius (ft), calculated as cross-sectional area (A, W) divided by wetted
perimeter (Wia, ft)
S = average reach slope (ft/ft)
values used in the computations and the resulting predictions are suAmnarized in the table
below.

For the reach downstream of Welhngford, particle sizes of 12 mm and finer are expected to be
mobile at the banlcfull discharge. Dowwtream of the trbutary confluence, the particle size at
incipient motion increases to 13 mm.
Pebble count collected from riffles and pools throughout the,study area have a Dso less than 2

bed shear stresses at the (design.) bankhM flow mobilize the majority but not all-of the
grain-size distribution. This suggests that the design diaxutel would not experience chronic
net aggradation or degradation over the long term.

USACE website at http://www.saw.usace.army.mil/wetlands/regtour.htm, or contact one of the field
offices listed on page 3 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 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 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 page 4 of this application).
Page 1 of 14
Coastal Area Management Act (CAMA) Coordination - If the project occurs in any of North Carolina's
twenty coastal counties (listed on page 4) the applicant should contact the North Carolina Division of
Coastal Management (DCM). DCM will determine whether or not the project is within a designated
Area of Environmental Concern, in which case DCM will act as the lead permitting agency. In such
cases, DCM will require a CAMA Permit and will coordinate the 404/401 Permits.
The applicant may also choose to coordinate with the United States Fish and Wildlife Service to ensure
that the proposed project will have no impact upon any endangered or threatened species or critical
habitat as regulated by the Endangered Species Act, and the State Historic Preservation Office, North
Carolina Department of Cultural Resources to ensure that the proposed project will have no impact upon
any properties listed or eligible for listing on the National Register of Historic Places. Compliance with
these regulations is required to be eligible for any Department of the Army permit. The addresses for
both agencies are listed on page 3 of this application.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office. 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.army.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/f`ees.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.

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
Page 9 of 14
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.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
hqp://h2o.enr.state.nc.us/ncwetlands/stnngide.html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at hM://h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:

XI. Stormwater (DWQ Only)
Describe impervious acreage (both existing and proposed) versus total acreage on the site.
Discuss stormwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
Prior to buy-out and demolition of the homes on the site, the approximate impervious area was
10,400 square feet. After construction of the restoration project, the only impervious area that
will be added as part of the project will be several concrete flumes (approximately 1,500 square
feet) and a potential parking area with pervious pavers (approximately 1,800 square feet). The
project will result in the removal of 7,100 square feet of impervious area.
XII. Sewage Disposal (DWQ Only)
