APPROVAL of Neuse River Buffer Rules
Dear Mr. Allen:
You have our approval to encroach into Zone 2 within the Neuse River Buffer for the purpose of constructing the
Corporation Parkway Sanitary Sewer Extension in Wake County, as described in the application received by the Division of
Water Quality on July 10, 2001. This approval is valid for the Neuse River Buffer Rules (15A NCAC 2B .0233). 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.
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 in writing and you may be required to send us a new application for a new approval. If the
property is sold, the new owner must be given a copy of the 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 of the Neuse
River Buffer Rules.
If you do not accept any of the conditions of this approval, 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 conforming to Chapter
150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-
7447. This approval 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 the Neuse Buffer Rules. If you have any
questions, please telephone John Dorney at 919-733-9646.
Sincerely,
Stevens

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.
The route of the sanitarv sewer was chosen to avoid environmental impacts and tree disturbance,
as much as possible. Also to appease adjacent property owner and align the sewer in the
approximate construction corridor of a new road. Check dams, rip-rap and silt fencing will be
used for erosion and sediment control along existing storm ditch lines.

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/ncwetiands/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.
**Affects Riparian Buffer Area, Zone 2 Only** (0.14 Acres)

Mr. Joe Langston
Dewberry & Davis, Inc.
5505 Creedmoor Rd, Ste. 150
Raleigh, NC. 27612-6352
Dear Mr. Langston:
The following is our report and recommendations as they pertain to our 25 February
2000 field investigations of three proposed sewerline segments in the City of Raleigh: 1)
Wade Avenue, approximately 500 LF between Glenwood Avenue and Filmore Street; 2)
Millbrook Road, approximately 600 LF near Hedgemoor Drive; and 3) Corporation Parkway,
approximately 800 LF east of New Hope Road. Robert J. Goldstein and Associates walked
all three proposed sewerline corridors and found no jurisdictional wetlands. Only one
jurisdictional waterway, a perennial stream which parallels Wade Avenue, will be crossed.
Providing that this stream crossing impacts less than 150 feet of stream channel, this project
may be permitted under either Nationwide Permit 26 and DWQ General Water Quality

3101. No Pre-Construction Notification (PCN) is required for construction. It is understood
that the final alignment of this segment is not yet designed. If the final alignment impacts 150
feet or more of stream channel, Pre-Construction Notification is required for Section 401/404
permitting.
The stream in the Wade Avenue project corridor is also subject to the Neuse River
Buffer Rule. Under this rule, vegetated riparian buffers are divided into two zones. Zone 1
is the first 30 feet landward from the top of the stream bank or shoreline, and zone 2 is an
additional 20 feet landward from zone 1. Acceptable activities within each zone are listed in
paragraph 6 of 15A NCAC 2B .0233, entitled Neuse River Basin: Nutrient Sensitive Waters
Management Strategy: Protection and Maintenance of Riparian Buffers, and are divided into
either Exempt, Allowable, Allowable with Mitigation, or Prohibited impacts. All impacts other
than those listed as exempt require approval from the Division of Water Quality (DWQ) prior
to beginning construction. Crossing the stream and both buffer zones perpendicular to the
channel in a construction corridor no wider than 40 feet is the only option which will be
considered exempt under the Neuse River buffer rules. Any other approach to crossing this
stream or its buffer will require approval from DWQ.
Mitigation for non-exempt impacts to riparian buffers will be decided by either DWQ
or the delegated local authority. A copy of the Neuse River buffer rules is available as a free
download from the DWQ website at http•//h2o enr state nc us/nns/tarp htm.
The proposed Millbrook Road segment will tie into an existing manhole located in zone
2, approximately 40 feet from the bank of a perennial stream. To ensure that this sewerline
is exempt from the Neuse River Buffer Rule, it will need to leave the manhole and traverse the

remainder of zone 2 perpendicular to the buffer.
The proposed Corporation Parkway segment is currently aligned parallel to an
intermittent channel, and traversing zone 2 of its buffer. The installation of non-electric utility
lines in zone 2 is exempt only as a perpendicular crossing. This proposed sewerline should
be realigned to insure that the final alignment falls outside zone 2.
Any deviation from the above recommendations will require pre-construction
notification and approval from DWQ. Please keep us informed as to final alignments and if we
