DEPARTMENT OF DEFENSE
Department of the Army; Corps of Engineers
Intent To Prepare a Draft Supplemental Environmental Impact
Statement (DSEIS) for the Nourishment of 25,000 feet of Beach in
Topsail Beach, Pender County, NC
AGENCY: Department of the Army, U.S. Army Corps of Engineers, DoD.
ACTION: Notice of intent.
-----------------------------------------------------------------------
SUMMARY: The U.S. Army Corps of Engineers (USACE), Wilmington District,
Wilmington Regulatory Field Office has received a request for
Department of the Army authorization, pursuant to Section 404 of the
Clean Water Act and Section 10 of the Rivers and Harbors Act, from the
Town of Topsail Beach to conduct a one-time emergency beach fill
project to protect oceanfront development and infrastructure until such
time that a federally authorized shore protection project can be
implemented. At this time, the construction date for the Federal
project is uncertain. A Draft General Reevaluation Report--
Environmental Impact Statement (GRR-EIS) has been prepared by the USACE
and was released for public review and comment in June 2006 (USACE,
2006). Given the current status of the GRR-EIS and the need for
Congressional authorization, funding, preparation of plans and
specifications, and right-of-way acquisition, the Federal project may
not be implemented until Fiscal Year 2010, or possibly later.
ADDRESSES: Copies of comments and questions regarding scoping of the
DSEIS may be addressed to: U.S. Army Corps of Engineers, Wilmington
District, Regulatory Division. ATTN: File Number SAW-2006-40848-071,
Post Office Box 1890, Wilmington, NC 28402-1890.
FOR FURTHER INFORMATION CONTACT: Questions about the proposed action
and DSEIS can be directed to Mr. Dave Timpy, Wilmington Regulatory
Field Office, telephone: (910) 251-4634.
SUPPLEMENTARY INFORMATION: The Topsail Emergency Beach Nourishment
project was placed on Public Notice on December 15, 2006 and a Notice
of Intent issued on December 15, 2006 (71 FR 75511). A Scoping Meeting
was held on January 16, 2007. Subsequently, another borrow area has
been found. Therefore, this Notice of Intent is issued to include
another borrow area into the project.
1. Project Description. The fill placement area will occur between
Godwin Avenue on the south to a point 2,000 feet northeast of Topsail
Beach/Surf City town limits, a total ocean shoreline length of
approximately 25,000 feet. The fill would consist of three sections, a
1,000-foot transition on the south beginning at a point opposite Godwin
Avenue, a 22,000-foot main fill section that would extend to the
Topsail Beach/Surf City town limits, and a 2,000-foot northern
transition (Figure 1). The project design will remain consistent with
the Federal design and will involve a berm system to be constructed to
a height of 7 feet NGVD. An optimum berm width of 50 feet is proposed.
The in-place volume of the beach fill has not been determined but could
range between 900,000 to 1,250,000 cubic yards. Offshore sand sources
are currently being investigated for sediment compatibility with the
native beach material. The offshore borrow areas under consideration
include all of the areas within the 3-mile North Carolina territorial
limit previously identified by the USACE in the GRR-EIS (Borrow Areas A
and B), areas lying outside of the USACE identified borrow areas, and
an area designated as Borrow Area X located closer to shore (Figure 1).
The navigation channel running through Banks Channel from New Topsail
Inlet through Topsail Creek and from Topsail Creek parallel to the
barrier island to the Atlantic Intracoastal Waterway (Figure 1) was
considered as a potential source for the one-time emergency beach fill
project but dismissed due to the small volume of material that would be
available. The authorized dimensions of the navigation channel are 80
feet wide at 7 feet below mean low water. During normal maintenance
operations, between 50,000 and 200,000 cubic yards are removed and
deposited on the south end of Topsail Beach. This relatively small
volume of maintenance material would fall well below the emergency
project requirements. Furthermore, maintenance dredging is currently
being performed in Banks Channel with the dredged material being placed
on the south end of Topsail Beach. The current maintenance operation
would totally deplete the volume of material available for beach
disposal for at least the next two years. Accordingly, the navigation
channels running behind Topsail Beach will not be given detailed
consideration for the emergency project.
The proposed construction timeframe for the emergency beach fill
activities will occur in late calendar year 2008 or early calendar year
2009.

vicinity of Topsail Beach, North Carolina.
Beach Fill Surveys & Design. Typical cross-sections of the beach
along the Topsail Beach project area will be surveyed. Nearshore
profiles will extend seaward to at least the -30-foot NAVD depth
contour. The total volume of beach fill to be placed in front of the
existing development and infrastructure will be based on an evaluation
of erosion of the project area from 2002 through the expected
construction date of the Federal project. Additional offshore and
inshore data for Hutaff Island will also be obtained along the northern
5,000 feet of the island. This data will be used in the evaluation of
possible impacts associated with the removal of sediment from the
selected offshore borrow area and for future impact evaluations
following project implementation through the use of numerical modeling.
Geotechnical Investigations. The offshore sand search
investigations have included bathymetric surveys, sidescan sonar
surveys, seismic surveys, cultural resource surveys, vibracore
collection and analysis, and ground-truth diver surveys to verify
existence or non-existence of hard bottoms. The results of the offshore
investigations coupled with the compatibility of the sand resource area
and native beach sand will be assessed to define the borrow area. All
sediment compatibility assessments will be based on State of North
Carolina sediment compatibility standards that went into effect in
February 2007.
Environmental Resource Coordination & Permitting. The USACE
prepared a General Reevaluation Report--Environmental Impact Statement
(GRR-EIS) for the larger Federal shore protection project. The interim
(emergency) beach fill project will be subject to Section 10 of the
Rivers and Harbors Act, Section 404 of the Clean Water Act and the
State Environmental Policy Act (SEPA).
Preliminary coordination with the USACE--Wilmington District
resulted in a determination that a Department of the Army Application
for an Individual Permit will be needed for project compliance with
Sections 10 and 404. Similarly, coordination with the North Carolina
Division of Coastal Management (NCDCM) determined that the project
would require a State EIS developed in accordance with SEPA; as well as
a Major Permit under the Coastal Area Management Act.
2. Proposed Action. The scope of activities for the proposed
emergency beach fill project included: (a) Vibracores in the identified
borrow area, (b) side scan sonar surveys of the ocean bottom, (c) in-
water investigations of potential near shore hard bottom resources
identified by the side scan sonar survey, and (d) beach profile
surveys. Offshore investigations included bathymetric surveys, sidescan
sonar surveys, seismic and cultural resource surveys, as well as
vibracore collection and analysis. The results of the offshore
investigations coupled with the compatibility of the sand resource area
and native beach sand will be assessed to define the borrow area.

3. Issues. There are several potential environmental issues that
will be addressed in the DSEIS. Additional issues may be identified
during the scoping process. Issues initially identified as potentially
significant include:
a. Potential impact to marine biological resources (benthic
organisms, passageway for fish and other marine life) and Essential
Fish Habitat, particularly Hard Bottoms.
b. Potential impact to threatened and endangered marine mammals,
birds, fish, and plants.
c. Potential impacts to water quality.
d. Potential increase in erosion rates to adjacent beaches.
e. Potential impacts to navigation, commercial and recreational.
f. Potential impacts to private and public property.
g. Potential impacts on public health and safety.
h. Potential impacts to recreational and commercial fishing.
i. The compatibility of the material for nourishment.
j. Potential economic impacts.
4. Alternatives. Several alternatives are being considered for the
proposed project. These alternatives will be further formulated and
developed during the scoping process and an appropriate range of
alternatives, including the No Action alternative, will be considered
in the Supplemental Draft EIS.
5. Scoping Process. Project Delivery Team meetings will be held to
receive comments and assess concerns regarding the appropriate scope
and preparation of the DSEIS. Participation in the meeting by federal,
state, and local agencies and other interested organizations and
persons is encouraged.
The COE will also be consulting with the U.S. Fish and Wildlife
Service under the Endangered Species Act and the Fish and Wildlife
Coordination Act, and with the National Marine Fisheries Service under
the Magnuson-Stevens Act and Endangered Species Act. Additionally, the
Supplemental Draft EIS will assess the potential water quality impacts
pursuant to Section 401 of the Clean Water Act, and will be coordinated
with NCDCM to determine the projects consistency with the Coastal Zone
Management Act. The USACE will closely work with NCDCM through the
SDEIS to ensure the process complies with all State Environmental
Policy Act (SEPA) requirements. It is the USACE and NCDCM's intentions
to consolidate both NEPA and SEPA processes to eliminate duplications.
6. Availability of the Draft Supplemental EIS. The DSEIS is
expected to be published and circulated in early 2008, and a public
hearing will be held after the publication of the DSEIS.
Dated: November 13, 2007.
