Enclosed is a check in the amount of $240.00 and a Pre-Construction Notification
(PCN) Application for Water Quality Certification, pursuant to Section 401 of Public Law
95-217. Please amend the original (enclosed) certificate for Wanchese Marsh Creation
and Protection Project, Wanchese, Dare County NC Roanoke Sound/Broad Creek [03-
01-51, 30-21-7, SA HQW] for the General Water Quality Certificate 3256, to increase the
authorized fill area from 8.0 to 8.7 acres.
The existing certificate authorizes 8 acres of fill to construct the Wanchese Marsh
Creation Project. Work completed to date covers an 8-acre footprint. The final phase of
work will lower the north dike to open the site to tidal exchange. We propose that the
limestone rock (300 cubic yards) and armor stone (200 cubic yards) from the dike
lowering, be placed in 0.2 acres of open water outside of and adjacent to the
containment dike to supplement the oyster reef component of the project. An additional
500 bushels of shell cultch will also be placed on up to 0.5 acres of additional estuarine
bottom in the immediate project vicinity. Open water areas inside the containment
structure are deep mud and not suitable to support the reef materials.
We have provided your office with seven copies of the PCN application (i.e., 6
copies to Raleigh NCDWQ and one copy to Mr. Al Hodge, NCDWQ, Washington, North
Carolina). Should you have any questions concerning the application, please contact
Mr. Chuck Wilson, Environmental Resources Section, at (910) 251-4746), e-mail

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. Work scheduled to proceed on
or after October 20, a period of lower biological productivity. Materials are stone and shell that
should not contribute significant turbidity. A floating silt curtain will be installed adjacent to the
dike lowering work area to reduce turbidity within the water column. Any activity inside the
dike will be contained on site.
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 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 (see DWQ website for most current
version.).

Dear Colonel Delonx:
The State of North Carolina has completed its review pursuant
to 15 CFR 930 Subpart C - Consistency for Federal Activities, of
the subject document. The project consists of constructing a
protective dike and using dredged material to construct
approximately 8 acres of coastal wetlands rear Wanchese Harbor at
Roanoke Island. The project will involve placing fill material in
the Public Trust and _stuarine Waters ?areas of Environmental
Concern. Dredged material from the Wanchese Harbor entrance
channel will be deposited behind a sandbag retaining wall, graded,
and slanted to construct an intertidal watland. The project is
being funded under Section 204 of the Water Resources Development
A-ct-of 1552, -and-is being sponsored by the-North Carolina Division
of Water Resources.
Dased upon our review, we agree with the Corps' determination
that the proposed Wanchass ':Marsh Creation Project 1s Consistent
with the North Carolina Coastal Management Trogram, Provided the
following conditions are met-
1. A 401 Water Quality certification is be obtained from the
Division of Water Quality, and all conditions therein are mot.

submitted at least 30 days prior to the initiation of land
disturbing activities.
3. Dredging and disposal will occur within the approved t-ime of
year windows for these activities in Wanchese Harbor. Work outside
of the windows will require advanced coordination and approval from
the appropriate state and federal agencies. Funding and or
contractor delays are not considered justification for working
during periods of peak biological activity-
The Division of Coastal Management continues to support the
efforts of the Beneficial Use of Dredged Material Work Group. We
appreciate the opportunity to work with the Corps and the Division
of Water'Resources on, the development of this project, and we are
hopeful for its success.
If you have any questions regarding our finding, conditions,

RE: Erosion and Sedimentation Control Plan No. Dare -2003-001
Wanchese Marsh Creation Project
Wanchese Harbor - Dare County
River Basin: Pasquotank
Date Received: August 19, 2003
Responsible Party: U. S. Army Corps of Engineers, Wilmington Distract
Dear Sir:
This office has completed its review of the erosion and sedimentation control plan for the
referenced 9.0 acre disturbance. Based on the information provided, we have determined the
submitted plan for the construction of a riprap dike for dredge spoil containment, if properly
implemented and responsibly maintained, should meet the intent and minimum requirements of the
Act. We, therefore, issue this LETTER OF APPROVAL.
In 1973, the Sedimentation Pollution Control Act (copy available upon request) was enacted.
It established a performance oriented program with the OBJECTIVE of PREVENTING
SEDEv4ENT DAMAGE to adjoining properties and/or natural resources resulting from land
disturbing activities through the use of reasonable and appropriate Best Land Management Practices,
based on the approved plan and changing site conditions, during the course of the project. AS Tg-E
DECLARED RESPONSIBLE PARTY YOUR RESPONSIBILITY is to understand the Act and
comply with the following minimum requirements of the Act and the above listed modifications (if
any):

This message provides a status report on the Wanchese Marsh Creation and Protection
Project. Marsh establishment has been successful with good spring growth after the fist
winter dormant season. We are finalizing plans for opening the site to increased tidal
exchange and to complete authorized oyster reef construction. I have attached the
Wanchese Marsh Creation and Protection Project Status Report and Plan for Project
Completion, dated June 2008, fully describing spring 2008 conditions and activities. It
also provides our plans to lower the North Dike with placement of excess rock and shell
cultch (as available) for oyster reef establishment and excavation of a small creek to
improve tidal exchange within the constructed marsh. The construction plan sheets and
the previous Wanchese Marsh 2007 Status Report are available at the following link:
ftp://ftp.usace.ann,y.mil/pub/saw/Wanchese%20Marsh/
We do not anticipate any significant impact from these actions; however, our intent is to
keep regulatory agencies fully informed of all project activities and details and request
your concurrence that existing clearances apply, so that we can begin the contracting
process in August 2008.
Coordination with the NMFS and NCDMF in regard to fish habitat has been thorough
and extensive beginning in 1996 and continuing throughout the NEPA and construction
process. The EA contained our finding that the project is not likely to adversely affect
any federally listed species and by letters dated April 9, 1999, NMFS and March 31,
1999, these agencies concurred with this finding. It is assumed that the CAMA
consistency letter dated November 2, 1999 and approval of the 401 Water Quality
Certification DWQ Project 01-1202 letter dated September 25, 2001 and other agency
approvals would still apply. All proposed work is within the 9 acre footprint described
in the EA / FONSI and 404b however, the 401 only authorized the 8 acres of fill for
containment and marsh construction that has already been placed. The stone from the
modified North dike (0.2 acres) and additional stone or shell (preferred if
available) cultch (0.5) acres will be placed adjacent to marsh within the 9 acre project
area as need to complete the 1 acre of oyster reef. The Wanchese Project oyster reef will
be similar to previous NCDMF oyster reef construction using stone and/or shell
cultch that are routinely covered by General Permit. This notification has also been
coordinated with our Washington, N.C. Regulatory Office. Since these are considered
details or minor modifications that do not increase the overall project scope, no additional
NEPA coordination beyond this notification is proposed, unless requested by regulatory
agencies.
The following responses were received
1. The NMFS has reviewed the plans for completion of the Wanchese Marsh
Creation and Restoration Project and concur with the work proposed plan to
complete this important collaborative project. We are pleased that this site
incorporates a beneficial use of dredged material component and after some
adjustments, further developed the technology and construction techniques for
this type of marsh restoration project. The Wanchese marsh will provide
important habitat for a variety of estuarine dependent fishery resources including
EFH for federally managed species. Ron Sechler,
NOAA, National Marine Fisheries Service
2. Looks great. Good work. We are OK with what is going on (no permit
modifications or additional coordination required). Just keep us informed as time
goes by. Mike Wicker USFWS
3. Our office concurs with the modifications you have described so long as there is
concurrence by NCDMF and NCWRC. Thank you for the opportunity to
comment. Frank Jennings NCDCM
4. The NC Division of Marine Fisheries approves of the project modifications. If
you have any questions please contact me. Sara Winslow NCDMF
5. I've reviewed the information regarding the modification of the current structures
at the Wanchese Marsh Restoration site and concur with the proposed changes in
design to accommodate completion of your project. Please know our agency
supports any recommendations requested by NCDMF. Thank you for the
opportunity to review and provide input on this project. Please continue to update
us as the project progresses to learn of its success or any necessary modifications
as they may occur. Maria T. Dunn North Carolina Wildlife Resources
Commission
6. We have reviewed your status report and plan for project completion, including
the drawings of the modifications that will be made. We approve and support
these proposed modifications. Please let us know if any additional state funds
will be required for this project. John Sutherland, NC Division of Water
Resources
7. If you have not already received a reply from LQ (Richard Peed), accept this as
our response. If more than an acre is to be disturbed then an erosion and
sedimentation control plan must be submitted to and approved by the LQS in the
Washington Regional Office Prior to initiating the project. Patrick H. McClain,
PE LQS
8. The disturbed area is approximately 0.2 acre and therefore should not require an
erosion/sediment control plan. William A. Dennis, PE Wilmington District
9. I've spoken with Kyle Barnes here in waro, I am mcmillan, and Cyndi Karoly in
the central office. We all agree that we need to amend the existing original 401
certification. The existing 401 is as I understand for 8.0 acres of surface water
impacts, the proposed plan would expand the impacts to 8.7 acres. Please prepare
a pen which should include a copy of the existing 401 as a modification request
for the amendment of this project thanks. AL Hodge NCDWQ
Wanchese Marsh Creation and Protection Project Status Report
June 2008
This is a status report on the Wanchese Marsh Creation and Protection Project. The
purpose is to describe current (spring 2008) site conditions and activities. This report
also provides our plans for the final construction phase that will open the site to full tidal
exchange. This report has been circulated to known interested agencies for review and
concurrence. The final construction phase is proposed for late summer or early fall 2008.
Introduction. The Wanchese Marsh Construction and Protection Project, North
Carolina, is a 12 acre ecosystem restoration/protection project. This project made
beneficial use of dredged material to construct wetlands and shallow water estuarine
habitat under the authority of Section 204 of the Water Resources Development Act of
1992, as amended. This project was recommended as a pilot site for wetland restoration
by the Beneficial Use of Dredged Material Work Group (an interagency committee of
State and Federal resource agencies) at a December 5, 1996, meeting hosted by the U.S.
Fish and Wildlife Service (USFWS). Individuals from the USFWS, National Marine
Fisheries, U.S. Army Corps of Engineers, North Carolina Division of Marine Fisheries
(NCDMF), North Carolina Division of Coastal Management, North Carolina Division of
Water Resources, North Carolina Wildlife Resources Commission, North Carolina
Division of Water Quality, and North Carolina Public Health, Pest Management, are
represented in this group.
Project Plan. The project includes construction of a brackish wind tide driven
(irregularly flooded) estuarine marsh/creek complex (8 acres) using dredged material,
placed within a protective stone dike, located immediately north of the Wanchese harbor
entrance. Adjacent waters and wetlands will be enhanced by construction of oyster reef
(1 acre) and chemical control of the noxious weed Phragmites and replanting with native
marsh vegetation (1 acre). This project will also protect additional wetlands (about 2
acres) previously threatened by erosion.
Clearances. Clearances include: (1) Section 240 Final Feasibility Report and Finding of
No Significant Impact, Wanchese Harbor Marsh Creation Project, NC signed July 1999,
(2) CAMA consistency letter dated November 2, 1999, (3) Approval of the 401 Water
Quality Certification DWQ Project 01-1202 letter dated September 25, 2001, (4)
Sediment Erosion Control Permit (No. Dare-2003-001) approval letter dated September
5, 2002, and (5) preconstruction and ongoing coordination with NMFS regarding EFH
and endangered species. Minor modifications during construction have been fully
coordinated with interested agencies. These modifications have not increased the overall
project scope and no additional NEPA coordination beyond notification and discussions
have been requested by regulatory agencies.
Project Status. The constructed marsh substrate and initial planting were completed in
2007. The project status at the end of the first growing season is described in the August
2007 Project Status Report (Attachment 1). Field inspection of the marsh construction
area during the spring of 2008 (Picture 1) generally found excellent resurgence of all
planted species after a first winter dormancy. Some minor goose damage was evident in
scattered areas especially on the ends of the sandy points located in the southwest
quadrant of the site (Picture 2) and limited plant retreat along the marsh fringe was
observed in some areas. Tracks and other sign indicate that muskrat or nutria may also be
present on the site and contributing to plant damage. The Emerald Forest (planting
contractor) installed replacement plants within the constructed marsh, conducted
herbicide treatments and initial planting in the Phragmites control area during May and
early June (See Table 1 for plant types and quantities). Three string and stake exclosures
were erected to provide short term protection from goose feeding (Picture 3). Portions of
the Phragmites control area, where 2007 herbicide treatments were effective, were
planted with 1,210, 2" Spartina cynosuroides plugs planted on 3' centers. Portions on the
site where 2007 herbicide treatments were ineffective were retreated with herbicide and
planting of Spartina patens was deferred until spring 2009.

Final Construction Phase: Lowering of the North Dike, Oyster Reef Construction
and Clean Up. Plans for summer/fall 2008 lowering of the North dike are shown on
attachment 2 and 3. This final construction phase will also include; oyster reef
construction, general cleanup of the site (removal of old outfall structure, filter fabric and
storm debris) and Phragmites control as needed. The plan is to lower the elevation of
the North dike so that the top of the rocks are at or below the high water elevation
providing a submersed weir. Stones will be placed adjacent to and offshore of the
existing stone dike. This submersed weir design provides marsh protection from
Northeasters, while allowing good water exchange, containment of the dredged material
within the site, and an additional 0.2 of an acre available for oyster attachment substrate.
The existing stone dike provides about 0.3 acres of submersed rock. An additional 5,000
bushels of cultch (preferably oyster shells) will be added as needed to establish the
project specified, one acre oyster reef.
2
The details of this work are shown on Attachment 2 (plate P-1) and Attachment 3 (plate
P-2). The present northern dike is about 250 feet in length and has a crest width of 11.0
feet and a top elevation of +3.0 feet (NGVD29). The proposed modifications call for the
lowering of the dike crest to improve water exchange between the sound and the marsh
by forming a low-sill and circulation-channel sections along the dike. The first 50 linear
feet of the dike will remain intact serving as a stable tie-in anchoring the constructed
marsh to the existing shoreline. Beginning at the 50-foot mark, the dike will transition to
a low-sill section having a top elevation of +1.4 feet (approximate MHHW) and crest
width of 15 feet. This section will start at the 70-foot mark and continue for the next 150
linear feet. The low sill section will be formed by repositioning the stone of the existing
dike along the sound-side perimeter of the structure. The final section of the low sill will
consist of a single layer of granite armor stone (15 feet wide) over a base of marine
limestone with an overall width of about 45 feet (as shown on P-2). The armor layer will
be within the intertidal zone (approximate tidal range of 0.5 feet) and is positioned such
that the top of the rocks will be covered at normal high tide. Further, the single layer of
stone consists of about 40% void space facilitating water exchange at all but extreme low
water events. The final 20 linear feet of the dike will be modified to form a circulation
channel section which will be open to water passage at all times. The cross section of the
channel will be 20-feet wide at the bottom with an elevation of -1.0 feet. This section
will be constructed by spreading the existing stone to form the specified dimensions. The
final extent of the channel will cover about 55 feet as measured along the centerline of
the new channel (i.e. at right angles to the dike alignment).
In addition to the dike modifications, a new connecting creek will be excavated within
the containment dike. It will be located along the inside edge of the remaining portion of
the northern dike (see P-1). The new creek will provide for a meandering water
connection between an existing "moat" present along the western perimeter of the marsh
to the open water of the enclosed basin. This will replace the previous outlet that has
shoaled and is not expected to be naturally sustainable in the original location. The creek
will be excavated through an area that served as a former stock pile during the prior
construction phase. To the degree practical marsh grasses within the creek template will
be relocated within the marsh restoration area prior to excavation. The excavated
sediments will consist primarily of a mix of sand, silts and pieces of marine limestone
bedding material. This material will be placed and graded between the new creek edge
and the remaining north dike to a maximum top elevation equal to that of the north dike.
All excavated materials and turbidity associated with construction will be contained
within the existing dike enclosure. The new creek will be about 75 feet long, 15 feet
wide, with a maximum bottom elevation of -1.5 feet.
Final phase of this construction will consist of general site clean-up of the project area.
This will include the removal and offsite disposal of all exposed geo-textile fabric. This
fabric was originally placed along the inside of the stone dike when it served as a dredged
material containment area during the first phase of construction. This fabric is in various
stages of deterioration and is no longer needed for the proper function of the project.
Likewise, a spillway located over the north dike will also be removed. This consists of a
36-in diameter concrete pipe with supporting timber frames, a corrugated steel spillway
riser and timber platform. Other manmade and natural debris which has collected within
the site will also be removed as part of the final clean-up.
