Issue Date: December 2, 2019 F
Comment Deadline: December 17, 2019
Corps Action ID Number: SAW-2008-03183
The Wilmington District, Corps of Engineers (Corps)received an application from the
North Carolina Department of Transportation (NC DOT) seeking Department of the
Army authorization to modify the standard permit for NC DOT on-going U-2579B
project, Corps File No., SAW No. 2008-03183. U-2579B is a section of the Winston-
Salem Northern Beltway, from US 158 to I-40 Business/US 421, in Forsyth County, near
Kernersville,North Carolina. This modification includes the relocation and backfill of 80
linear feet of an unnamed tributary to Smith Creek and 1,711 linear feet of Smith Creek,
to accommodate the northbound on-ramp to the newly constructed Winston-Salem
Northern Beltway. NC DOT would relocate the stream channels using Natural Channel
Design.
Specific plans and location information are attached. Plan sheets and this Public Notice
are available on the Wilmington District Web Site at:

Applicant: North Carolina Department of Transportation

Authority
The Corps evaluates this application and decides whether to issue, conditionally issue, or
deny the proposed work pursuant to applicable procedures of the following Statutory
Authorities:
® Section 404 of the Clean Water Act(33 U.S.C. 1344)
❑ Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. 403)
❑ Section 103 of the Marine Protection, Research and Sanctuaries Act of 1972
(33 U.S.C. 1413)

and 1,570 linear feet of temporary impacts. There is no change to wetland impacts. The
two (2)ponds that will be drained and filled total 7.82 acres of open water impacts.
NC DOT has determined that the only option for the construction of the northbound on
ramp to the Winston Salem Northern Beltway in this location is to relocate Smith Creek
and its unnamed tributary from the proposed road fill. A culvert option was evaluated,
but the length of the culvert would complicate maintenance and inspections (located
under a travel lane),would have drainage complications, is cost prohibitive, and was
overall determined to be structurally unsound.
Avoidance and Minimization
The applicant provided the following information in support of efforts to avoid and/or
minimize impacts to the aquatic environment:
The avoidance of Smith Creek and the unnamed tributary to Smith Creek cannot occur,
as NC DOT determined Smith Creek has undermined the existing I-40 Business road
slopes, and has down-cut considerably with recent storms. Piping Smith Creek(and the
unnamed tributary) for over 2,000 linear feet in a travel lane proves close to impossible
for NC DOT to maintain the culvert, which would have drainage complications, and has
been found to be structurally unsound. These conditions make placing Smith Creek in a
culvert at this project location cost-prohibitive. If successful,relocating Smith Creek and
the unnamed tributary using Natural Channel Design, should result in more functional
stream channels then existing conditions. F
Compensatory Mitigation
The applicant offered the following compensatory mitigation plan to offset unavoidable
functional loss to the aquatic environment:Natural Stream Design would be employed to i
relocate the stream channels. Smith Creek is currently incised and does not have access
to a floodplain throughout most of its length in the project area. The newly relocated i
channels, should provide stable meandering channels,with vegetated banks. The newly
relocated streams should have/gain access to floodplains, before re-entering Smith Creek
downstream of the project area. The NC DOT will monitor the site for 5 years, and if the
relocated streams prove to be stable, and the planted vegetation survives, the relocated
streams would be considered a success. However, the Corps may decide to require
compensatory mitigation from the North Carolina Division of Mitigation Services, if
functions and services of the stream channels are not replaced sufficiently to compensate
for functions and services lost by the relocations.
Cultural Resources
Pursuant to Section 106 of the National Historic Preservation Act of 1966,Appendix C of
33 CFR Part 325, and the 2005 Revised Interim Guidance for Implementing Appendix C,
the District Engineer consulted district files and records and the latest published version
of the National Register of Historic Places and initially determines that:
Version 6.15.2017 Page 3

Based upon all available information,the Corps determines that this application
for a Department of Army (DA)permit does not involve an activity which would
affect the coastal zone, which is defined by the Coastal Zone Management(CZM)
Act(16 U.S.C. § 1453).
Evaluation
The decision whether to issue a permit will be based on an evaluation of the probable
impacts including cumulative impacts of the proposed activity on the public interest.
That decision will reflect the national concern for both protection and utilization of
important resources. The benefit which reasonably may be expected to accrue from the
proposal must be balanced against its reasonably foreseeable detriments.All factors
which may be relevant to the proposal will be considered including the cumulative effects
thereof; among those are conservation, economics, aesthetics, general environmental
concerns, wetlands, historic properties, fish and wildlife values, flood hazards,flood plain
values (in accordance with Executive Order 11988), land use,navigation, shoreline
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 discharge of dredged or fill materials in waters of the United States,the evaluation of
the impact of the activity on the public interest will include application of the
Environmental Protection Agency's 404(b)(1) guidelines.
Commenting Information
The Corps of Engineers is soliciting comments from the public; Federal, State and local
agencies and officials, including any consolidated State Viewpoint or written position of
the Governor; 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 F
species, historic properties,water quality, general environmental effects and the other
public interest factors listed above. Comments are used in the preparation of an
Environmental Assessment(EA)and/or an Environmental Impact Statement(EIS)
pursuant to the National Environmental Policy Act(NEPA). Comments are also used to
determine the need for a public hearing and to determine the overall public interest of the
proposed activity.
Any person may request, in writing, within the comment period specified in this notice,
that a public hearing be held to consider the application. Requests for public hearings
shall state,with particularity, the reasons for holding a public hearing. Requests for a
public hearing will be granted, unless the District Engineer determines that the issues
raised are insubstantial or there is otherwise no valid interest to be served by a hearing.
The Corps of Engineers, Wilmington District will receive written comments pertinent to
the proposed work, as outlined above,until 5pm,December 17, 2019. Comments should
