DWQ Project # 08-0290
Old Lexington Road Improvements
Winston-Salem, North.Carolina
Dear John and Sue:
HDR Engineering, Inc. of the Carolinas (HDR), on behalf of the City of Winston-Salem
(City), is herein providing updated impact calculations for our previously submitted PCN
.for a Nationwide Permit #14 (and DWQ. GC #3704). The project involves widening Old
Lexington Road from 2 to 3 lanes in southern Winston-Salem (Forsyth County, NC). The
project's intent is to improve traffic safety and congestion. An existing culvert needs to be
replaced due to deterioration, lack of hydraulic capacity, and exposed utility lines through
the barrel that increase the potential for debris blockage. Due to the widening, the culvert
will be lengthened, primarily on the downstream end, and rip-rap outlet protection will be
used. The previous impact calculations for the proposed culvert replacement/extension
involved 75 feet of perennial stream channel.
During a site review with DWQ on February 28, 2008, we determined that a side channel
that had previously been deemed ephemeral was actually intermittent, per DWQ's stream
identification protocol. In addition, the mainstem perennial stream was found to be actively
eroding alarge bank area due to trash and debris accumulation upstream of the culvert inlet.

Design Revisions and Updated Impact Calculations.
Old Lexington Road Improvements
May 21, 2008
It. was determined that the best approach to this would be to remove the trash/debris, re-
align the channel to its original position and allow for connectivity to the culvert inlet. Our
design plans have accommodated these changes _and,updated stream impacts are attached to
this letter. The intermittent side channel will be filled and relocated to provide a stable
confluence with the mainstem channel, which will involve 63 linear feet of impact. The
trash/debris removal, fill and culvert extension in the.perennial stream will involve 142
linear feet (0.043 acres) of impact.
We hereby respectfully request a new Nationwide 14• permit. reflecting these impacts, to
replace the previously-issued permit dated February 22, 2008. We also respectfully request
authorization under DWQ GC 3704. Thank you in advance :for your assistance. If you
have any questions or require additional information after your review of the enclosed
information, please contact me at [phone].
Sincerely,
John Jamison

Re: Section 401 Water Quality Certification for the Old Lexington Road Improvements
Dear Ms. Keyser:
On February 12, 2008, the North Carolina Division of Water Quality (DWQ) received your application for a 401 General
Water Quality, to impact 75 linear feet of an unnamed tributary to Salem Creek in Forsyth County in order to conduct
road improvements on Old Lexington Road in Winston-Salem, NC. Additional information is required in order that we
may determine your project's compliance with 15A NCAC 211.0500. The DWQ will require this information in order to
process your application to impact protected wetlands and/or streams on the subject property. Therefore, we will place
this project on hold as incomplete until we receive this additional information, and if we do not receive the additional
information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H
.0506. Please provide the following information so that we may continue to review your project.
On February 28, 2008, Sue Homewood from the DWQ, in the presence of John Jamison, agent for this project,
conducted a site visit and performed intermittent/perennial stream determinations. An additional unnamed
tributary was identified at the impact site. This additional channel was not shown in design drawings for the
project. The channel was determined to be an intermittent stream based on the DWQ's stream rating protocol.
Based on the results of this determination the DWQ will require a new site plan and impact calculations for your
project.
This on-site determination shall expire five (5) years from the date of this letter. Landowners or affected parties
that dispute a determination made by the DWQ or Delegated Local Authority that a surface water exists and that it
is subject to the buffer rule may request a determination by the Director. A request for a determination by the
Director shall be referred to the Director in writing c/o Cyndi Karoly, DWQ, 401 Oversight/Express Review
Permitting Unit, 2321 Crabtree Blvd., Suite 250, Raleigh, NC 27604-2260. Individuals that dispute a
determination by the DWQ or Delegated Local Authority that "exempts" surface water from the buffer rule may
ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. Applicants
are hereby notified that the 60-day statutory appeal time does not start until the affected party (including
downstream and adjacent landowners) is notified of this decision. DWQ recommends that the applicant conduct
this notification in order to be certain that third party appeals are made in a timely manner. 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, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This determination is final and
binding unless you ask for a hearing within 60 days.
2. In addition to the additionally identified channel, new documentation should address the recent severe %osion and
channel reformation that has occurred at the existing culvert inlet. No Carolina

Please respond in writing within 30 calendar days of the date of this letter by sending a copy of this information to Sue
Homewood at the address on this letterhead, and a copy to Ian McMillan N. C. Division of Water Quality, Wetlands/401

information within that timeframe, please provide written confirmation that you intend to provide the requested
information, and include a specific timetable delineating when the requested materials will be provided. If we do not hear
from you in 30 calendar days, we will assume that you no longer want to pursue this project and we will consider the
project as returned.
This letter only addresses the application review and does not authorize any impacts to wetlands, waters or protected
buffers. Please be aware that any impacts requested within your application are not authorized (at this time) by the
DWQ. If you have any questions, please contact Sue Homewood, DWQ, Winston-Salem Regional Office, at 336-
