Reference the application of GWC Properties, LLC dated May 22, 2006 and received by
this office on June 20, 2006, for Department of the Army (DA) authorization to excavate and
enlarge an existing basin, new bulkhead and retaining wall, access walkway, floating dock, finger
pier, and boatlifts to accommodate seven slips at The Vineyards at Pages Creek in New Hanover
county, North Carolina. The project includes enlarging the existing 86' x 32' basin to 86' x 52'
to accommodate four 12' x 12' boatlifts. The 86' x 52' basin will be excavated to final water
depths from -4.0 6 to -6.0 ft relative to Normal Low Water (NLW). The access channel to the
basin will be maintained to a dimension of 104' x 40' and water depth of -6.0 NLW. The total
excavation volume for the 86' x 52' basin is approximately 1,800 cy and will be placed in an
onsite upland 172' x 93' disposal area. The project also includes approximately 80' of
replacement bulkhead, located 2 feet water ward of the existing structure, and 18' of new
bulkhead to stabilize the new basin shoreline. The project also includes a 26' x 2' finger pier
located within the basin and two 32' x 4' boatlift access walkways and 120' x 6' floating dock
along the eastern side of the access channel. The referenced project will be constructed as shown
in the permit application plans dated June 7, 2006.
The Federal agencies have completed review of the proposal as presented by the
application and your field investigation report.
We recommend that the following conditions be included in the State authorization:
1. All work authorized by this permit must be performed in strict compliance with the
attached plans, which are a part of this permit. Any modification to these plans must be approved
by the US Army Corps of Engineers (USAGE) prior to implementation.
2. The permittee understands and agrees that, if future operations by the United States
require the removal, relocation, or other alteration, of the structure or work herein authorized, or
if, in the opinion of the Secretary of the Army or his authorized representative, said structure or
work shall cause unreasonable obstruction to the free navigation of the navigable waters, the
permittee will be required, upon due notice from the U.S. Army Corps of Engineers, to remove,
relocate, or alter the structural work or obstructions caused thereby, without expense to the
United States. No claim shall be made against the United States on account of any such removal,
relocation, or alteration. The permittee shall notify NOAA/NATIONAL OCEAN SERVICE
Chief Source Data Unit N CS261, 1315 E West HWY- RM 7316, Silver Spring, MD 20910-
3282 at least two weeks prior to beginning work and upon completion of work.
3. Except as specified in the plans attached to this permit, no excavation, fill or
mechanized land-clearing activities shall take place at any time in the construction or
maintenance of this prof ect, in such a manner as to impair normal flows and circulation patterns
within waters or wetlands or to reduce the reach of waters or wetlands.
4. The replacement bulkhead will not be positioned farther waterward than 2 feet from
the normal water level elevation contour at any point along its alignment.
5. Except as authorized by this permit or any USACE approved modification to this
permit, no excavation, fill or mechanized land-clearing activities shall take place at any time in
the construction or maintenance of this project, within waters or wetlands. This permit does not
authorize temporary placement or double handling of excavated or fill material within waters or
wetlands outside the permitted area. This prohibition applies to all borrow and fill activities
connected with this project.
6. Unless otherwise authorized by this permit, all fill material placed in waters or
wetlands shall be generated from an upland source and will be clean and free of any pollutants
except in trace quantities. Metal products, organic materials (including debris from land clearing
activities), or unsightly debris will not be used.
7. All mechanized equipment will be regularly inspected and maintained to prevent
contamination of waters and wetlands from fuels, lubricants, hydraulic fluids, or other toxic
materials. In the event of a spill of petroleum products or any other hazardous waste, the
permittee shall immediately report it to the N.C. Division of Water Quality at (919) 733-5083,
Ext. 526 or (800) 662-7956 and provisions of the North Carolina Oil Pollution and Hazardous
Substances Control Act will be followed.
8. The authorized structure and associated activity must not interfere with the public's
right to free navigation on all navigable waters of the United States. No attempt will be made by
the permittee to prevent the full and free use by the public of all navigable waters at or adjacent
to the authorized work for reason other than safety.
9. All excavated materials will be confined landward of the mean high water level
elevation contour within adequate dikes or other retaining structures to prevent spillover of
dredged materials into any vegetated wetlands or surrounding waters.
2
10. A water control structure will be installed at the intake end of the effluent pipe
leading from the retention area in order to ensure maximum settlement of suspended solids.
11. Flow from the diked retention area will be confined by pipe, trough, or similar device
to a point at or below the mean low water level elevation contour to prevent gully erosion and
siltation.
12. If the permittee discovers any previously unknown historic or archeological remains
while accomplishing the authorized work, he will immediately notify the Wilmington District
Engineer who will initiate the required coordination procedures.
13. The permittee shall advise the Corps in writing at least two weeks prior to beginning
the work authorized by this permit and again upon completion of the work authorized by this
permit.
14. The permittee shall require its contractors and/or agents to comply with the terms and
conditions of this permit in the construction and maintenance of this project, and shall provide
each of its contractors and/or agents associated with the construction or maintenance of this
project with a copy of this permit. A copy of this permit, including all conditions, shall be
available at the project site during construction and maintenance of this project.
15. The permittee shall employ all sedimentation and erosion control measures necessary
to prevent an increase in sedimentation or turbidity within waters and wetlands outside the permit
area. This shall include, but is not limited to, the immediate installation of silt fencing or similar
appropriate devices around all areas subject to soil disturbance or the movement of earthen fill,
and the immediate stabilization of all disturbed areas. Additionally, the project must remain in
full compliance with all aspects of the Sedimentation Pollution Control Act of 1973 (North
Carolina General Statutes Chapter 113A Article 4).
16. The activity will be conducted in such a manner as to prevent a significant increase in
turbidity outside the area of construction or construction-related discharge. Increases such that
the turbidity in the waterbody is 50 NTU's or less in all rivers not designated as trout waters by
the North Carolina Division of Environmental Management (NCDEM), 25 NTU's or less in all
saltwater classes and in all lakes and reservoirs, and 10 NTU's or less in trout waters, are not
considered significant.
17. The permittee, upon receipt of a notice of revocation of this permit or upon its
expiration before completion of the work will, without expense to the United States and in such
time and manner as the Secretary of the Army or his authorized representative may direct, restore
the water or wetland to its pre-project condition.
18. Violations of these conditions or violations of Section 404 of the Clean Water Act or
Section 10 of the Rivers and Harbors Act must be reported in writing to the Wilmington District
U.S. Army Corps of Engineers within 24 hours of the permittee's discovery of the violation.

19. The West Indian manatee (Trichechus manatus), which is listed as a federally
endangered species, has been reported in the waters in New Hanover County. In order to protect
the West Indian manatee all work should be done during the period from November 1 to May 31.
If work must be done during the period from June through October the enclosed guidelines,
entitled "Precautions for General Construction in Areas Which May Be Used by the West Indian
Manatee in North Carolina" must be followed.
