I am in receipt of your letter dated March 30, 2004. Item no. 1 states that $275.00 additional fee
must be provided. That process has been initiated and the check should be mailed to you this
week.
Last Friday I attempted to contact Mr. Mike Horan by phone, 919/715-3404, and left a message.
Also, found an email address for Mr. Mike Horan and sent a message to him. So far I have not
received a response via either mode of communication.
I trust that the additional $275.00 is all that is lacking in this permit submittal. If not please
contact me at your earliest convenience and I will make every effort to honor any requirement.

AMMENDED APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Wyatt:
On September 2, 2004 the Division of Water Quality (DWQ) received your amended plan for the proposed
impacts to an unnamed tributary to South Buffalo Creek. These impacts are associated with the widening of
South Elm-Eugene Street in Greensboro. The Division of Water Quality has reviewed this amended plan and
finds the modifications acceptable. Accordingly, the City of Greensboro has our approval, in accordance with
the attached conditions, to place permanent fill in 148 linear feet of perennial stream for the purpose of
widening South Elm-Eugene Street in Greensboro, Guilford County, as described in your application received
by the Division of Water Quality on April 24, 2004, and in additional correspondence received on May 4, 2004,
August 27, 2004 and September 2, 2004. After reviewing your application, we have determined that this fill is
covered by General Water Quality Certification Number 3404 which can be viewed on our web site at
http://h2o.enr.state.nc.us/ncwetlands. This Certification allows you to use Nationwide Permit Number 14 when
it is issued by the U.S. Army Corps of Engineers. In addition, you should secure any other applicable federal,
state or local permits before you proceed with your project, including (but not limited to) those required by
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 valid only for the purpose and design that you have described in your application. If you
change your project, you must notify us in writing 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, as
well as the additional conditions listed below:
The culvert required for this project shall be installed in such a manner that the original stream profile is
not altered (i.e. the depth of the channel must not be reduced by a widening of the streambed). Existing
stream dimensions (including the pattern and profile) are to be maintained above and below the
location of the culvert. The culvert shall be designed and installed to prevent head cutting of the
stream. If the culvert becomes perched, the appropriate stream grade shall be re-established or, if the
culvert is installed in a perched manner, the culvert shall be removed and re-installed correctly. The
Applicant must submit a plan and receive written approval from this Office to address any head cutting
that will occur as a result of this project (e.g., use of cross vanes downstream of the culvert).
2. Where riprip is required for energy dissipation and scour protection, it shall be limited to the minimum
dimensions specified by appropriate engineering calculations. Riprap may only be used below the

Dear Mr. Wyatt:
RE: Widening of South Elm-Eugene Street
DWQ # 04-0464
Guilford County
On May 27, 2004, the Division of Water Quality issued a`401 Water Quality Certification for fill of
120 linear feet of stream in order to widen South Elm-Eugene Street in Greensboro. This amount of
stream impact was based on the original application for the project dated March 15, 2004 and a site visit
made by DWQ staff from our Winston-Salem Regional Office on April 8, 2004. However, in a modification
for this project dated May 19, 2004 (received May 24, 2004) from Mr. Lee Adams of Wilbur Smith
Associates, the amount of requested stream impact was 135.5 feet.
The Division has carefully examined the revised site plan provided by Mr. Adams in a letter dated
March 23, 2004 (received on May 4, 2004) which is cited in our May 27 approval. We have discussed
these results with Ms. Andrea Wade of the Raleigh Regulatory Field Office of the US Army Corps of
Engineers in order to provide a consistent review of the revised application. Our measurements of the
proposed impact is as follows:
Existing culvert length - 58 feet
Existing stream channel to be culverted
Above road crossing 38 feet
Below road crossing 47 feet
Riprap proposed to be installed in the stream
Above road crossing 33 feet
Below road crossing 34 feet
Therefore, a total of 152 feet of stream are proposed to be impacted by culverting or riprap rather
than the 120 feet approved in our May 27 letter or the 135.5 feet reported in the modified application dated
May 19, 2004. The discrepancy seems to be that the reported impact does not account for the existing
sinuocity of the channel. In addition, we are not certain whether the length of riprap to be installed below
the road crossing is sufficient to address channel erosion issues that are the typical concern of the NC
Division of Land Resources.

1-877-623-6748
In summary, the 401 Certification that the Division issued on May 27, 2004 will need to be
modified to account for the actual proposed impact in accordance with 15A NCAC 2H .0507 (d) since both
the original and modified applications were incorrect. Also if total stream impacts equal or exceed 150
linear feet, then compensatory stream mitigation will be required by any revised Certification. Please call
me at 919-733-9646 to discuss this matter and to develop an approach which will allow DWQ to issue a
modified 401 Certification for this project. I would also suggest that a joint phone conference with Ms.
Wade, Mr. Daryl Lamb of our Winston-Salem Regional Office and myself might be useful in order to
address these issues in a comprehensive manner. Thank you for your assistance in this matter.
yours.

From: Daryl Lamb <[e-mail]>

To: John Dorney <[e-mail]>
John,
Just so you'll know where the original numbers came from, here's a quick review. The amended
application I received on May 20th listed a proposed impact of 127.51f of new culvert and 37.5 if of
impact due to riprap outlet protection for a total impact of 1651f. In an attached addendum, the existing
box culvert was listed as 451f in length. This yielded a net impact of 1201f. Subsequently we have
learned that the existing culvert length is 58 if and the total proposed channel impact is 201 if due to the
need to relocate the channel slightly to accommodate the new, longer culvert. The resulting channel in
the impact footprint would be 1941f, a net loss of 71f. In addition, the actual riprap pads as indicated on
the print dated 4/22/04 (the latest revision that I received) measure -32.51f on the inlet side and -341f
on the outlet side. The culvert design length, as measured on the same print, is 127.5 If. This yields a
total footprint of -194 If for the new culvert installation. The actual total net impact would be 201 if
(length of original channel impacted) - 581f (length of existing culvert) = 143 if (if the design riprap
dimensions are actually used). If larger inlet/outlet pads are required, the impact will probably exceed
1501f. Clearly there was a disconnect between the impact dimensions listed on the amended PCN and
those of the structures illustrated on the installation print. I failed to catch this discrepancy, and that led
to the issuance of an authorization for an under-reported impact. It didn't help that there was apparently
some confusion or miscommunication between the City of Greensboro and the consulting engineers
(Wilbur Smith Associates). In a telephone conversation with Wilbur Smith Associates earlier this week,
I requested that they provide the engineering data and calculations used to arrive at the proposed outlet
protection pad dimensions. You should be receiving a copy of those numbers soon. If you need any
additional information, let me know.
Best regards,
Daryl

andrea found some problems with the application (after we had issued the 401) and upon more careful
review, john hennessy and i found even more problems. the bottom line is that they will need a new
401 and mitigation unless they redesign. also john h is not sure whether the downstream riprap is
long enough - please have the DLR folks weigh in on that and coordinate with andrea too since she
expressed that concern.
i have not sent the letter yet (but will need to early next week). if all of you could get me comments

rP 'gnment of the stream approximately 5 feet north of its present location. There will be a net loss
201 If minus 1941f ) of 7 If of stream channel due to this realignment. This realignment will place the
crossing within 15 degrees of perpendicular to the stream. The roadway design also includes curb
and gutter for stormwater collection- The collected stormwater will be routed to a stilling basin and
disc g ad over a level spreader. This will provide eneray dissipation and sheet flow to the
stormwater before it enters the stream channel.

evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.
Provide a written description of the proposed impacts: Directly upstream of the proposed
structure, the tributary is going to be gradually widened to the width of the structure (24 feet).
Directly downstream of the proposed structure, the tributary is going to be reformed from 24
feet wide to the existing width.

* List each impact separately and identify temporary impacts. Impacts include, but are not limited to: mechanized clearing, grading, fill,
excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding.
** 100-Year floodplains are identified through the Federal Emergency Management Agency's (FEMA) Flood Insurance Rate Maps
(FIRM), or FEMA-approved local floodplain maps. Maps are available through the FEMA Map Service Center at 1-800-358-9616, or
online at http://www.fema.gov.
*** List a wetland type that best describes wetland to be impacted (e.g., freshwater/saltwater marsh, forested wetland, beaver pond,
Carolina Bay, bog, etc.) Indicate if wetland is isolated (determination of isolation to be made by USACE only).
List the total acreage (estimated) of all existing wetlands on the property: None
Total area of wetland impact proposed: None

** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest
downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at
www.usas.gov. Several internet sites also allow direct download and printing of USGS maps (e.g., www.tol2ozone.com,
www.mapquest.com, etc.).
Cumulative impacts (linear distance in feet) to all streams on site: The proposed culvert
length is 127.5 feet and the existing culvert length is 58 feet. This results in a culvert impact
length of 69.5 feet in addition to the 66 feet of rip ro protection impact There is a total
impact length of 135.5 feet which is less than 150 feet therefore there is no need for
mitigation plans.
4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic
Ocean and any other water of the U.S.) below:

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
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.
Measures were taken to impact the least amount of stream as possible. The proposed hvdraulic
structure could have been shorter if it were placed perpendicular to the roadway. However, by

Addendum to Hydraulic Study
South Elm-Eugene Street
As a result of a field visit and phone conversation with Mr. Daryl Lamb, DWQ
Winston-Salem, it was determined that modifications to the initial design are appropriate.
The initial design widens the stream upon approaching the culvert and it contracted back
to its original width after exiting the culvert. The problem of aggregation at the entrance
of the culvert was addressed at both the field visit and during the phone conversation with
Mr. Lamb. In order to resolve this issue, two five foot wide earth banks extending
through the culvert were placed on each inside wall of the culvert which resulted in a
channel the same width of the stream running through the culvert. The top of these earth
banks are approximately one-half foot above everyday flow conditions. Once the water
surface elevation rises above these earth banks, water will spread utilizing the entire
width of the culvert.
The second issue addressed is the stilling basin dumping directly into the stream.
There is a concern with dumping by the outlet of pipe directly into the stream. In order to
resolve this problem, a level spreader has been placed at the outfall of the stilling basin
pipe which will allow the water to sheet flow across natural ground before entering the
stream.

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The current site is a two-lane roadway. There is an existing 4
foot wide by 6 foot tall reinforced concrete box culvert crossing under South Elm-Eugene
Street. Primarily, the surrounding general land use is residential.
10. Describe the overall project in detail, including the type of equipment to be used: The
proposed project is to convert a two-lane roadway to a four-lane divided roadway. It has
been requested that the hydraulic structure handling the tributary crossing under South Elm-
Eugene Street accommodate the 100-year storm without overtopping the proposed roadway
elevation. In order to meet this request, a 24 foot span by 6 foot rise (buried 1 foot) precast
reinforced concrete three sided culvert will replace the existing 4 foot wide by 6 foot tall
reinforced concrete box culvert. The equipment to be used in the construction phase of this
project will consist of typical heavy machinery such as motor graders backhoes bulldozers
paving equipment, crane, etc.
11. Explain the purpose of the proposed work: This project has been developed to meet future
traffic demands due to the future development consisting of commercial sites The existing
reinforced concreted box culvert is undersized to accommodate the design storm therefore a
new hydraulic structure, precast reinforced concrete three sided culvert, must replace the
existing structure.

Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Size of watershed draining to pond: Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
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.
Measures were taken to impact the least amount of stream as possible. The proposed hydraulic
structure could have been shorter if it were placed perpendicular to the roadway. However, by
skewing the structure, we were able to connect both ends of the proposed structure to the existing
tributary with minimum impacts. Also, proper erosion control devices will be placed throughout
Page 9 of 13
the project to limit any unnecessary disturbance. The structure is also bottomless which in turn
minimizes impacts on the existing tributary.
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.
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
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. 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.
To mitigate minor impacts, a bottomless structure is proposed with rip-rap scour protection.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of

Purpose

• The purpose of this report is to study the impact of the proposed precast reinforced concrete three sided
• culvert, including the associated roadway profile, on the existing flood elevations. The proposed roadway and
precast reinforced concrete three sided culvert are included in the proposed South Elm-Eugene Street
construction project by Wilbur Smith Associates. See Figure 5 for the location of the proposed precast
reinforced concrete three sided culvert.
Introduction

i The proposed precast reinforced concrete three sided culvert crossing under South Elm-Eugene Street
(Guilford County, NC) is located approximately 420 feet North Northwest of Elmsley Drive crossing under
South Elm-Eugene Street and containing a tributary of South Buffalo Creek. Currently there is 4 foot wide by
• 6 foot tall reinforce concrete box culvert at this location and the over bank cover is predominantly light woods
and grass coverage.

• This hydraulic study will provide a comparison between the existing and post-construction conditions, flood
• stages and flood profiles at the proposed South Elm-Eugene Street precast reinforced concrete three sided
culvert crossing. This task is accomplished by developing hydraulic models for the existing and post-
construction conditions utilizing EEC-RAS 3. 1.1 computer program (US Army Corps of Engineers). The
. procedures and methodologies used to complete this hydraulic study are in accordance with North Carolina
Department of Transportations (NCDOT) and Federal Emergency Management Agency (FEMA) criterion.

• South Buffalo Creek
The tributary to South Buffalo Creek flowing habit is a perennial stream. The stream consist of well defined
• banks and a narrow floodplain.
During the site visit, a slow flowing, well defined stream was observed with a slight bend located just
downstream of the proposed outlet of the culvert. By there being a bend in this particular location, proper
• erosion control measures have been taken in the design to eliminate migration of the stream at the outlet of the
proposed culvert.

• Hydraulic Study
This tributary has not been previously studied by FEMA in this particular location. However, by observation
and reviewing FEMA data upstream of this particular tributary, a safe assumption of the discharge and
. floodway was made in order to design the proposed culvert. Table 1 represents the flood discharges at the
location of South Elm-Eugene Street and the proposed culvert.

• Table 1 shows the flood discharges determined by observation and reviewing FEMA data upstream of this
. particular tributary. These discharges are used in the hydraulic models for the existing and post-construction
conditions.

1. Survey
Ground data and contour files were obtained from the Borum, Wade and Associates, P.A. The
contour files were used to develop the necessary cross sections to populate the HEC-RAS hydraulic
model geometry files. This task was accomplished by using ArcView 3.2 (ESRI) and HEC-GeoRAS
(US Army Corps of Engineers). The survey data obtained from the Borum, Wade and Associates,
P.A. was referenced to the NAVD 1983 datum.
2. Boundary Conditions
The existing conditions model is calibrated using flood discharges determined by observation and
reviewing FEMA data upstream of this particular tributary. The flood profiles included in the
observation and review for starting water surface elevations for the 10-, 50- and 100-year flood events
are also used for calibration of the existing conditions. Figure 1 and Table 2 represent the existing
conditions hydraulic model.

Post-Construction Conditions Hydraulic Model
The purpose of developing the post-construction hydraulic model is to study the impact of the
proposed roadway and precast reinforced concrete three sided culvert on the existing flood stages. The
post-construction hydraulic model is developed by observation and reviewing FEMA data upstream of
this particular tributary,. The post-construction hydraulic model is developed by super imposing the
proposed precast reinforced concrete three sided culvert and roadway approaches onto the calibrated
existing conditions hydraulic model. Additionally, minor ground modifications are included to the
river stations located immediately upstream and downstream of the proposed bridge crossing to
accommodate the proposed abutments (river stations 108.213 and 107.093).
The proposed precast reinforced concrete three sided culvert data are:
• Total length = 127.5 feet.
• Span of 24 feet.
• Rise of 6 feet with 1 foot buried.
• Inlet Invert Elevation = 762.45 feet
• Outlet Invert Elevation = 761.15 feet
3
Conclusion
Based on the output data from the post-construction hydraulic model (Table 4), the proposed precast
reinforced concrete three sided culvert and roadway approaches will not increase the existing 100-year
flood elevations. Refer to Tables 3 and 4 for a detailed comparison between the post-construction
and existing flood elevations. Table 3 provides a comparison between the post-construction and
existing flood elevations and Figure 2 provides a graphical comparison between the post-
construction and existing flood elevations. Figure 3 shows a plan view of the proposed precast
reinforced concrete three sided culvert with 100-year floodplain extents. See Figure 6 for a layout of the
proposed precast reinforced concrete three sided culvert.

Rock Riprap Design
Using HEC-11 (Federal Highway Administration) procedures to calculate the median (D50) rock
riprap required for slope protection.
D50 = 0.001 V3 / (d a,g) h K 1.5
Where
D50 = Median rock riprap size in ft.
V = Flow velocity, 100-year flood event (fps) = 4.65 fps
d avg= Average flow depth in channel, 100-year flood event (ft.) = 7.2 ft.
K = Correction factor = [ 1 - (sin 20/ sin 2 ch) ] 1/2 = 1.00
6 = Bank angle with the horizontal = 10 °
cis = Angle of repose of the rock riprap material = 40 °
D50 = 0.037 ft = 0.45 inch
Based on the North Carolina DOT 2002 Standard Specifications for Roads and Structures,
Section 1042, Rip Rap Material (page 10-67), Table 1042-1 (Acceptance Criteria for Rip Rap and
Stone for Erosion Control), Class 2 rock rip rap is equivalent to AASHTO class FACING riprap
gradation.
Class 1
Minimum stone size = 5 inches
Median stone size = 9 inches
Maximum stone size = 17 inches
Therefore, use Class 1 rock riprap for erosion and scour protection at the abutments, the riprap
mat should be 2.00 feet minimum thickness and extend to the top of the abutment. The riprap mat
should extend the full width of the abutments and be keyed into the channel bank to provide
stability against sliding.

Addendum to Hydraulic Study for South Elm-Eugene Street Culvert Replacement
Channel Realignment
Currently there is a 4 foot wide by 6 foot tall 45 foot long reinforced concrete box
culvert crossing under South Elm-Eugene Street which contains a tributary to South
Buffalo Creek. Due to criteria set by the City of Greensboro, a 127'/2 foot long, 24 foot
span precast reinforced concrete three-sided culvert has been proposed to replace the
existing reinforced box culvert. The existing stream makes an abrupt turn prior to
entering the existing structure. By replacing the existing structure, there must be a slight
realignment of the stream. The proposed structure is rotated approximately 15 degrees
clockwise to the existing structure and is shifted approximately 5 feet to the North of the
existing structure. By placing the culvert as previously described, there is a net loss of
stream length. Currently the stream is 201 feet long from beginning of reformation to
end of reformation. The proposed conditions result in a stream length to 194 feet, which
is a net loss of 7 feet. Immediately upstream of the reformation, the stream is
approximately 13 feet wide and immediately downstream of the reformation the stream is
approximately 15 feet wide. In between these two particular points, the stream constricts
to run through the 4 foot wide culvert and expands once exiting the culvert. The
proposed conditions will begin widening the stream from the 13 foot wide section so the
stream can pass through the 24 foot wide proposed structure and will constrict once
exiting the culvert to return to existing conditions at the 15 foot wide section immediately
down stream.
