PUBLIC NOTICE
THE NORTH CAROLINA DEPARTMENT OF TRANSPORTATION, DIVISION OF
HIGHWAYS, (NCDOT), POST OFFICE BOX 25201, RALEIGH, NORTH CAROLINA 27611-
5201, HAS APPLIED FOR A DEPARTMENT OF THE ARMY (DA) PERMIT TO
AUTHORIZE THE PROPOSED DISCHARGE OF FILL MATERIAL IMPACTING A TOTAL
OF 0.20 ACRE OF WATERS OF THE UNITED STATES, CONSISTING OF 0.02 ACRE OF
WETLANDS, 1,099 LINEAR FEET OF STREAM, AND 2 SMALL PONDS, FOR
CONSTRUCTION OF SECTION B OF THE IMPROVEMENTS TO SR 1652 (HARRISON
AVENUE) (T.I.P. NO. U-2804B), CROSSING UNNAMED TRIBUTARIES TO BLACK
CREEK, AND ADJACENT WETLANDS, FROM SOUTH OF NC 54 (MAYNARD
PARKWAY) TO SOUTH OF WESTON PARKWAY, IN CARY, WAKE COUNTY, NORTH
CAROLINA.
The following description of the work is taken from data provided by the applicant. Plans
submitted with the application show the placement of fill material impacting a total of 0.20
acres of waters of the United States, including wetlands. These impacts are necessary for the
construction of Section B of the improvements to SR 1652 (Harrison Avenue) (T.I.P. No. U-
2804B), crossing unnamed tributaries to Black Creek, and adjacent wetlands, from south of NC
54 (Maynard Parkway) to south of Weston Parkway, in Cary, Wake County, North Carolina.
The project will involve fill impacts to 0.18 acre of unvegetated waters of the United States.
These impacts to stream channels (1,099 linear feet) and 2 small ponds occur at 8 locations
throughout the project. At stream crossings, culverts or pipes will be used to allow for adequate
hydrological flow underneath the roadway. The proposed construction will also impact 0.02
acres of vegetated wetlands by filling and mechanized clearing. The impacted wetlands are a
small palustrine, wooded, headwater wetlands.
A portion of the impacted streams will be relocated to 295 linear feet of constructed channel
that will be designed using natural stream channel design principles. NCDOT is proposing
payment to the North Carolina Wetland Restoration Program to provide 920 linear feet of
compensatory stream mitigation for the remaining 460 linear feet of stream impacts that require
mitigation.

The purpose of the work is to provide for safer and more efficient road travel in the Harrison
Avenue road corridor and at its interchange with I-40. The applicant has considered several
alternatives to the proposed project, including the no-build alternative, project postponement,
alternative modes of transportation, asymmetrical widening, and alternative interchange designs.
In addition, the applicant has committed to investigating measures to avoid and minimize
wetland and stream impacts, including minimal use of riprap in stream channels, and use of
check dams within a riprapped channel to decrease flow velocities and reduce downstream
sedimentation. A Federal environmental assessment for this project was completed by the
NCDOT, and approved by the Federal Highway Administration on October 31, 1995.
Overall plans showing the proposed construction are included with this public notice.
Additional detailed plans may be reviewed at the U.S. Army Corps of Engineers Regulatory
Field Office at 6508 Falls of Neuse Road, Suite 120, Raleigh, North Carolina 27615-6846, or at
the offices of the North Carolina Division of Water Quality at the address shown below.
The State of North Carolina will review this public notice to determine the need for the
applicant to obtain any required State authorization. No Department of the Army permit will be
issued until the coordinated State viewpoint on the proposal has been received and reviewed by
this agency, nor will a Department of the Army permit be issued until the North Carolina
Division of Water Quality has determined the applicability of a Water Quality Certificate as
required by PL 92-500.
This application is being considered pursuant to Section 404(b) of the Clean Water Act (33
U.S.C. 1344). Any person may request, in writing within the comment period specified in the
notice, that a public hearing be held to consider this application. Requests for public hearing
shall state, with particularity, the reasons for holding a public hearing.
The District Engineer has consulted the latest published version of the National Register of
Historic Places for the presence or absence of registered properties, or properties listed as being
eligible for inclusion therein, and the project does not impact any registered property or property
listed as being eligible for inclusion in the Register. Consultation of the National Register
constitutes the extent of cultural resource investigations by the District Engineer. NCDOT has
conducted surveys for architectural resources, and has coordinated with the North Carolina State
Historic Preservation Officer (SHPO). SHPO has concurred that the project will not have any
effect on architectural or archaeological resource properties eligible for inclusion in the Register.
The District Engineer is otherwise unaware of the presence of such resources. Presently,
unknown archeological, scientific, prehistoric, or historical data may be lost or destroyed by work
under the requested permit.

3
The District Engineer is not aware, based on available information, that the activity will affect
species, or their critical habitat, designated as endangered or threatened pursuant to the
Endangered Species Act of 1973.
The decision whether to issue a permit will be based on an evaluation of the probable impacts,
including cumulative impacts, of the proposed activity and its intended use on the public interest.
Evaluation of the probable impacts which the proposed activity may have on the public interest
requires a careful weighing of all those factors which become relevant in each particular case.
The benefits which reasonably may be expected to accrue from the proposal must be balanced
against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and
if so the conditions under which it will be allowed to occur, are therefore determined by the
outcome of the general balancing process. That decision should reflect the national concern for
both protection and utilization of important resources. All factors which may be relevant to the
proposal must be considered including the cumulative effects thereof. Among those are
conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values,
fish and wildlife values, flood hazards, flood plain values, land use, navigation, shore erosion and
accretion, recreation, water supply and conservation, water quality, energy needs, safety, food
and fiber production, mineral needs, considerations of property ownership, and, in general, the
needs and welfare of the people. For activities involving the placement of dredged or fill
materials in waters of the United States, a permit will be denied if the discharge that would be
authorized by such permit would not comply with the Environmental Protection Agency's
404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or
criteria, a permit will be granted unless the District Engineer determines that it would be contrary
to the public interest.
The Corps of Engineers is soliciting comments from the public; Federal, State, and local
agencies and officials; Indian Tribes, and other interested parties in order to consider and
evaluate the impacts of this proposed activity. Any comments received will be considered by the
Corps of Engineers to determine whether to issue, modify, condition, or deny a permit for this
proposal. To make this decision, comments are used to assess impacts on endangered species,
historic properties, water quality, general environmental effects, and the other public interest
factors listed above. Comments are used in preparation of an Environmental Assessment and/or
Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments
are also used to determine the need for a public hearing and to determine the overall public
interest of the proposed activity.
Generally, the decision whether to issue this DA permit will not be made until the North
Carolina Division of Water Quality (NCDWQ) issues, denies, or waives State certification
required by Section 401 of the Clean Water Act.
4
The NCDWQ considers whether or not the proposed activity will comply with Sections 301, 302,
306, and 307 of the Clean Water Act. The application and this public notice for the DA permit
serves as application to the NCDWQ for certification.
Additional information regarding the Clean Water Act certification may be reviewed at the
offices of the Wetlands /401 Unit, North Carolina DENR, Division of Water Quality, 4401
Reedy Creek Road, Raleigh, North Carolina. Copies of such materials will be furnished to any
person requesting copies upon payment of reproduction costs.
All persons desiring to make comments regarding the application for Clean Water Act
certification should do so in writing delivered to the North Carolina DENR Division of Water
Quality, Wetland/401 Unit, 1621 Mail Service Center, Raleigh, NC 27699-1621, on or before
January 3, 2000, Attention: Mr. John Dorney.
Written comments pertinent to the proposed work, as outlined above, will be received in this
office, Attention: Eric Alsmeyer, until 4:15 p.m., on or before January 10, 2000, or telephone
919-876-8441, extension 23.
