2a. Name of nearest body of water (stream, river, etc.) to Core Sound
proposed project:
2b. Water Quality Classification of nearest receiving water: SA; ORW
2c. River basin: White Oak
3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The breakwater project area is a Corps of Engineers breakwater constructed to protect the entrance channel into Atlantic
Harbor. Damaged by Tropical Storm/Hurricane Ophelia in 2005, most of the area is now open water. Water from Atlantic
Harbor is presently mixing with Core Sound water, a combination which has resulted in shellfish closure of the immediate
project area.
DA 26 is an existing upland diked disposal facility adjacent to Core Creek, just north of NC Hwy 101 bridge, in Carteret
Co. Site is routinely used for disposal of sandy material dredged from AIWW in Core Creek landcut. In between disposal
events, underlying property owner actively removes sand material via one or more dike "cuts". This removal is presently
occurring.
3b. List the total estimated acreage of all existing wetlands on the property:
N/A
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
None
3d. Explain the purpose of the proposed project:
Reconstruct the breakwater to reestablish protection to the entrance channel to Atlantic Harbor.
3e. Describe the overall project in detail, including the type of equipment to be used:
Prior to the deposition of any material, a turbidity curtain will be installed around the work area at Atlantic. Dump trucks
will transport material from the DA to the breakwater by roadway. Upon arrival at the Atlantic Harbor of Refuge, fill
material will be deposited adjacent to existing high ground. The contractor will use this deposited material to fill sandbags
(each approx 15 feet long by 5 feet wide by 2 feet high) to construct a retaining wall along the west side of the
breakwater. Any breaks/weak areas along the existing sandbag wall on the east side of the breakwater (constructed by
Carteret County in 2006) will be repaired using new bags filled similarly to the bags used on the west side. The sandbag
wall would be + 1 foot Mean High Water (MHW). Prior to placing the bags, some smoothing of the wall alignment might
be required. Once all sandbags have been filled, sand will be gradually pushed and shaped by bulldozer from the high
ground within the sandbag structures to reconstruct the breakwater. The breakwater would be constructed with 10:1 side
slopes and a top elevation of +6 feet MHW.
The Corps' Coastal Engineering has advised the use of stone toe protection on the outside of the eastern sand bag
structure to protect and increase bag life. If funding is available, this stone toe protection will be included in this project. If
not, it may be constructed in the future when and if funding becomes available. At this time, few details or project
specifics for the stone have been determined. If the stone toe protection is constructed as a component of this project,
filter fabric will be installed on the inside of the stone and no repair or replacement of the eastern sand bag structure
would be required. Sand would be pushed over the sand bags to the edge of the stone. The side slopes and top
elevation would remain the same as described above.

4. Jurisdictional Determinations
4a. Have jurisdictional wetland or stream determinations by the
Corps or State been requested or obtained for this property /
? Yes ®No ? Unknown
project (including all prior phases) in the past?
Comments:
4b. If the Corps made the jurisdictional determination, what type

of determination was made?
4c. If yes, who delineated the jurisdictional areas? Agency/Consultant Company:
Name (if known): Other:
4d. If yes, list the dates of the Corps jurisdictional determinations or State determinations and attach documentation.
5. Project History
5a. Have permits or certifications been requested or obtained for ® Yes ? No ? Unknown
this project (including all prior phases) in the past?
5b. If yes, explain in detail according to "help file" instructions.
Site is a previously functional breakwater, constructed by the Corps in 1972. The project was included in the 1976 Final
Environmental Impact Statement, "Maintenance of the Waterway Between Pamlico Sound and Beaufort Harbor, North
Carolina".
The Corps prepared a consistency determination, dated July 27, 1982, regarding dredging and disposal of material on the
east bank of the existing sand breakwater. By letter dated August 23, 1982, NCDCM concurred with the determination
6. Future Project Plans
6a. Is this a phased project? ®Yes ? No
6b. If yes, explain.
Possibly. The sandbag and breakwater construction will occur this year. Stone toe protection is dependent upon
available funding. If funding not available to include in present project, it is likely to be constructed at some time in the
future, when funding becomes available. The Corps believes this construction should occur sooner rather than later
,
since the stone will protect integrity of bags and lengthen their functional lives. However, at this time, no contingencies
have been made for timing if not included in this year's construction

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Project is designed to reconstruct the previously existing structure. Originally designed to pump dredged material directly to
site, grain-size analysis proved too fine-grained a material. Features incorporated into project design (see below) to minimize
turbidities
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Construction will occur within footprint of previous breakwater. Sandbags will be placed to outline footprint of structure, a
turbidity curtain will be installed around project area, and dry sand will be pushed into water - all of which will limit turbidities
