2321 Crabtree Boulevard, Suite 250
Raleigh, North Carolina 27604
Dear Ms. Karoly,
Subject: City of Raleigh- House Creek Sewer
Replacement
DWQ Project # 07-0108
Mr. Masengill from the City of Raleigh received your January 31, 2007 letter on
February 2, 2007 requesting more information. In turn, Hazen and Sawyer has
reviewed your comments and has arranged for a meeting with Ms. Amy Chatman
to discuss this matter in further detail. After meeting with Ms. Amy Chatman it
was decided to redesign several of the stream crossings. Please find below our
answers to your comments as well as five copies of the additional information
that you requested.
Additional Information as Requested
1. After speaking with Ian McMillian and Amy Chatman, the temporary impacts
of perennial streams were limited to 40 ft. Therefore, Supplemental Sheet for
Item V14 has been modified and the total stream impact in linear feet is 635. The
table of cumulative impacts listed in Section V1 was also modified to match the
635 linear feet total. As a reminder, 395 feet is remove and replacement, 120
feet is new impacts for Phase I, and 120 feet is new impacts for Phase II.
2. Stream crossing No. 1, 3 and 10a and 10b were redesigned to be
perpendicular to the stream.
3. After speaking with Ian McMillian and Amy Chatman, the widths for the
maintenance corridor for stream impacts have been limited to 40 ft. The City of
Raleigh currently maintains a 20 to 40 ft sewer easement at the indicated
locations. These existing limits are noted on the drawings.

4. Supplement Sheet for Item VI 4 indicates the impacts that are new
(superscripts 2-4). This amounts to 120 feet for Phase I and 120 feet for Phase
II. All constructions limits within creek crossing were limited to 40 ft. The new
and larger line size does not require widening of existing easements.
5. Section VIII Mitigation response was entered as "N/A" because the impacts to
the streams are all temporary. The buffer table located in Section X has been
revised and no longer shows required mitigation. However, the square footage
for buffer 1 and 2 remains listed in the table.
If you have any further questions please feel free to contact me at 704-357-3150.
Thank you for your time,
Very Truly Yours,
Hazen and Sawyer, P.C.

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. This project replaces an
existing sanitary sewer with the maiority of the construction being done within the existing
maintained sewer easement. Due to constraints of limited accessibility, short lengths, rock
outcrops, and projected high costs, horizontal directional drilling was not practical.
VIII. Mitigation N/A- all temporary impacts
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
Updated 11/1/2005
Page 9 of 12

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 January 15, 2002, 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 NCEEP 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/ncwetl ands/strm~ide.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.
N/A
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please
