MEMORANDUM FOR: All Participants
SUBJECT: FY 94 Dredging Coordination Meeting
1. The FY 94 Dredging Coordination Meeting was held in Wilmington, North
Carolina on 18 August 1994. The agenda for this meeting is included as
attachment 1, dredging projects for FY 95 are included as attachment 2, and
attendees are listed as attachment 3. Following is a synopsis of the meeting and
required follow-up actions.
2. Review of FY 95 Operation & Maintenance (O & M) Protects. i?
Eleven (11) O & M dredging projects are scheduled for FY 95 and are listed ?
in attachment 2. Discussion on this topic was limited as most of the areas to
be dredged in FY 95 are dredged on an annual basis and no changes to past
dredging practices are anticipated. The projects discussed included:
a. Alligator Pungo Land Cut (AIWW). In the past, dredged material from
this channel was placed, on the toe of the bank, however, in FY 95 the dredged
material will be placed in upland diked disposal sites along the north bank of
the channel. An EA/FONSI for this work was completed in November 1993.
b. AIWW Inlet Crossings. The AIWW inlet crossings will be dredged as
usual. Material from Lockwoods Folly Inlet Crossing will be pumped to Long
Beach. During the discussion of inlet crossings 2 questions regarding dredging
of other areas were raised:
1) A question was asked regarding the status of dredging in the AIWW
between Surf City and New River Inlet (Section III, Tangents 2-6). The EA for
this project is currently out for 30-day review. Assuming no unresolved issues
arise during the comment period, it is anticipated that a FONSI will be signed.
A Public Notice will be circulated and dredging should take place in FY 95.
2) A DEM representative asked why material from Shinn Creek and Bogue
Inlet Crossing was placed in upland diked disposal sites rather than being pumped
to the beach. It was stated that due to the pumping distance and small amount
of material from these areas, it was infeasible to pump the material to the
beach. This led to a discussion of the recent amendments to the Dredge and Fill
Law. The implications of the new legislation are not fully understood at this
time. The Corps is in the process of putting together a coordinated response to
the Division of Water Resources with regard to the new legislation in an effort
to determine the implications of the amendments.
C. Wilmington Harbor - Anchorage Basin and 38-Foot Project. These
projects will go out on two separate contracts. Material from the Anchorage
Basin will go to Eagle Island and dredging is scheduled to take place in
September or October 1994. The 38-Foot Project will be dredged in October 1994
and material will go to the Ocean Dredged Material Disposal Site (ODMDS).
d. Channel from Back Sound to Lookout Bight. A concern was raised
regarding the deterioration of sandbags at the Harkers Island disposal site. The
Corps will investigate this problem the next time material is placed on Harkers
Island.
e. Wainwright Slough. Dredged material from Wainwright Slough is usually
placed on the channel-side toe of Wainwright Island. However, this material is
being washed back into the channel at an undesirably fast rate. The Corps will
investigate alternative disposal sites, one of which would be the back side of
the island. It is thought that resources of concern (SAV)-might be present on
the back side of the island, therefore, any changes to the current method of
disposal would be looked at carefully and coordinated with all appropriate
agencies. Walker Golder of the National Audubon Society stated that Wainwright
Island desperately needs more dredged material for bird habitat. Mr. Golder
provided attendees with the numbers of nesting terns on Wainwright Island for the
past few years. Just a few years ago, 6000 to 8000 pairs of terns were nesting
on Wainwright Island, last year 2000 pairs nested, and this year 0 pairs nested.
The Corps indicated that a decision regarding dredged material disposal for this
project would be forthcoming.
f. Cape Fear River Above Wilmington. This project is done routinely with
a pipeline dredge and toe-of-the-bank disposal. However, the Corps is
investigating the possibility of using a sidecast dredge for upcoming. work. This
will be coordinated with all interested agencies.
g. Wilmington Harbor - Ocean Bar Channel. This project will entail the
deepening of the channel to its authorized depth of 401. This dredging is
scheduled to start in September 1994 and will require the removal of rock;
disposal of the rock is discussed in paragraph 3.j..
h. Morehead City Harbor - Outer Harbor (Ocean Bar Channel). This will be
dredged in FY 95. Hydrographic surveys have not yet been completed. The
nearshore berm associated with this project is discussed in paragraph 3.i.
3. Project/Study Updates.
a. AIWW Longterm Study - The purpose of this study is to develop a 50-year
maintenance and management plan for the AIWW. This will be accomplished in three
(3) phases: Phase I - Acquisition of aerial photography, Phase II - A plan of
action, and Phase III - Data collection and analysis leading to a management plan
(to cover the next 50 years). Funding for this project has been sporadic over
the past few years. However, Construction-Operations (Corps) has stated that
they are committed to funding this study for the next 3 years in order that it
may be completed. During this discussion three (3) questions were raised:
1) What changes for the AIWW, if any, are envisioned? Will there be
changes in uses of the AIWW, maintenance, management, etc.? No major changes to
current practices are envisioned. The purpose of the long-term study is to
compile all available data in an attempt to project future maintenance needs of
the AIWW. Two significant portions of the study will involve investigation of
areas for future disposal and investigation of encroaching development on the
AIWW. 7,
2) Will it be feasible to include analyses of dredged material as
part of this study? Yes, sediment analyses will be conducted for the main
purpose of determining the availability and location Qf beach quality material.
These analyses will be a significant part of Phase IT of the study. Also, in
Phase III of the study, the Corps will investigate the possibility of pumping
dredged material from previously used disposal sites to the beach.
3) Is the Corps surveying disposal sites to determine their
availability for future use? Yes. Numerous sites have already been surveyed and
sites that could prove to be useful in the future will be surveyed during Phase
III of the long-term study. As part of this process the Corps will be looking
closely at easements, piers, etc. that may affect the accessibility of potential
disposal sites.
b. Morehead City Harbor. This project was completed last year. There was
some concern about the impacts of the project on nearshore fisheries and a study
regarding those impacts has been completed by North Carolina Division of Marine
Fisheries (NCDMF). Generally, the study, referred to as the "Mullet Project
Report," found that impacts were insignificant. Copies are available in Morehead
City office of NCDMF.
c. Sandbagged Disposal island - Old House Channel. During the FY 94
dredging coordination meeting the possibility of changing the current method of
sandbagging on this island was discussed. The suggestion was made by the Corps
to pump material onto the island and then sandbag it, rather that sandbagging the
island.prior to pumping material. However, due to the timing of dredging it was
decided to revert to the previously used method of placing the sandbags then
pumping material. Work on this project is ongoing. At this time approximately
1/4 of the sandbags have been placed on the island. Mitigation for this is
discussed in paragraph 3.f.
d. Colonial Nesting Waterbird Islands. The two islands in the Cape Fear
River, Ferry Slip and South Pelican Islands were considered for placement of
material from the Wilmington Harbor 38-foot project in FY 95. Ferry Slip Island
was surveyed and is right at 7 acres, the allowed size. South Pelican Island was
not surveyed but is believed to also be about 7 acres. Therefore, no material
will be disposed of on either island in FY 95. We will continue to monitor the
two islands and hopefully place material on them, as needed. The need to try to
maintain the nesting habitat at Big Foot Slough was discussed. Big Foot Slough
is a sandbagged disposal site which after disposal is at or above mean high
water. However, the material washes away within a year's time and habitat is
lost. The Corps agreed to investigate possible solutions. A question was raised
regarding the initiation of this investigation and it was decided that Tom
Henson, NCWRC, would head up the investigation through the Colonial Waterbird
Comittee and report back to the Corps. The majority of the agencies present are
partners to the Colonial Waterbird Cooperative Agreement and a meeting will be
called soon to discuss the concerns. Trudy Wilder, is the Corps colonial
Waterbird representative. Walker Golder gave statistics on numbers of colonial
nesting waterbirds in North Carolina and stated that 66%- of all waterbirds in
North Carolina nest on undiked dredged material disposal islands. The erosion
of Battery Island was also brought to everyone's attention. Battery Island has
the largest population of wading birds in North Carolina and erosion is causing
trees to fall into the water. The Corps was asked to help with this situation
if possible.
e. SAV Impact Assessment, Walter Slough Channel. The 1990 emergency
dredging of Walter Slough channel was conducted with a sidecast dredge. To do
the work in this manner, the Corps made the commitment to determine the impacts
on SAV. The Corps has been working with NMFS to assess impacts on SAV. This
study has been complicated by difficulty in obtaining good quality maps on which
to overlay aerial photography. However, recently the NMFS obtained maps from the
Department of Commerce and analysis of the photos should be completed by the end
of August 1994.
f. Oyster Reef Construction - Manteo (Shallowbag Bay) Project. Islands
along the Oregon Inlet Channel are used by the Corps for dredged material
disposal. As mitigation - for every acre of shallow water bottom covered by
dredged material, 0.66 acres of oyster reef will be created by the Corps. Sixty-
seven (67) acres of oyster reefs will be constructed. The North Carolina
Division of Marine Fisheries is responsible for identifying suitable sites for
oyster reefs. However, due to an oyster disease that is affecting some areas,
sites are limited. A question was raised regarding the limitations/boundaries
of the oyster reefs and whether or not they had to be located near the project
site. The Corps' response was that it is required that the oyster reefs be
located in the vicinity of the project. This would include Roanoke Sound or the
northern portion of Pamlico Sound. Ongoing research of the production of oyster
reefs is being used by NCDMF.
g. Biological Study, Beach Disposal Projects. Although monitoring of the
impacts of beach disposal on various organisms has been carried out by several
individuals and agencies, there are gaps in the data as well as duplication of
data in some cases. The Corps has contracted with UNCW to do a detailed
literature search on impacts of beach disposal on various organisms. Three areas
will be looked at: the dry beach, the intertidal zone, and the surf zone. The
schedule is for work to begin in August with a final report due in June of 1995.
The goals of the literature search are to identify gaps in available data, to
identify additional research needed, and to identify management implications of
the findings. For copies of the proposal, see Frank Yelverton.
h. Dredging Window. The Corps has multiple dredging windows for various
areas and types of dredging, such as Primary Nursery Areas, beach disposal,
hopper dredging, etc., all of which were set up to avoid dredging during
biologically sensitive times of the year. However, dealing with these different
windows often causes management problems. It was suggested that a small working
group of interested agencies be formulated to address this issue. The main goal
of this committee would be to look at all available data and based on that data,
determine which dredging windows are the most beneficial. It was the general
consensus that this was a good idea and the committee to address this issue
should be kept as small as possible. The following representatives agreed to be
points of contact for this project: Mike Street (NCDMF), Howard Hall (USFWS),
Larry Hardy or Ron Sechler (NMFS), Tom Henson (NCWRC), Howard Varnam (COE-Con-
Ops), and Bill Adams (COE - Environmental). It was sug%ested that an academic-
type might be helpful to this committee, however, the general feeling was that
the group should be kept very small and academic-types could be consulted during
the process of analyzing available data or could be contacted for input after
solutions are reached. The schedule for this work is not known at this time'.
i. Nearshore Berm Project, Morehead City, Beaufort Inlet. The Corps
proposes to construct a nearshore berm on the west side of Beaufort Inlet as a
means of keeping the dredged material in the ebb tide delta system. The berm
would be located on.the 25' to 30' contour, which is on the outer edge of the ebb
tide delta. The berm will rise approximately 6' above the current bottom contour
(slope of 1V:30H). The natural movement of the material should be back toward
the delta, thus keeping the material in the system. There has been some concern
about impacts to larval fish. Baseline data has been gathered and NMFS (Beaufort
Lab) will be doing a study to monitor impacts of the berm on larval fish. Berm
migration will be monitored by the Corps over the next 2 to 3 years. An EA for
this project is in the process of being finalized at this time. Assuming all
clearances are gbtained, work would begin in the fall of 1994. A question was
asked regarding the plans for future additions to the berm should impacts be
found to be insignificant. The Corps stated that the berm may be extended,
moved, etc. depending on its migration. As stated previously, the Corps will
monitor berm movement to determine what future actions, if any, will be
necessary.
j; Beneficial Uses - Rock Dredging, Cape Fear River Bar Channel. The
Corps has a unique opportunity to make beneficial use of the rock that will have
to be dredged in order to deepen the bar channel to its authorized depth. Plans
are to use the dredged rock to construct on offshore structure, known as the
Wilmington Offshore Fish Enhancement Structure (WOFES). The WOFES will be
located east of the ocean Dredged Material Disposal Site .(ODMDS), will be 8000
linear feet (in the shape of the Greek letter "pi" (H)),, and will extend from 12'
to 21' off of the bottom. A clearance of at least 25 (water depth) at mean
lower low water will remain for navigational purposes. The Corps has committed
to pre- and post-monitoring of the structure. A concern was raised regarding the
need for blasting to remove the rock. It was stated that the contractor thinks
he can dig the rock out without blasting and there are very tight environmental
constraints on blasting so that it is discouraged. A question was raised
regarding the placement of buoys at the WOFES. The Corps stated that river
pilots would most likely be opposed to the placement of buoys at the site as they
may cause confusion to boat pilots (marker buoys may be mistaken for navigational
buoys). It was decided that the Corps would work this problem out with all
concerned parties, including the Coast Guard and river pilots to come up with an
agreeable solution.
k. Habitat Creation/Restoration/Coastal America Program. The Corps is
involved in habitat creation and restoration under the following innitatives or
authorities.
1) The Co s National Mar3.ne riatsaa?? --
MOA - The Corps has made a commitment to investigate opportunities with the
NNFS to create/restore fisheries habitat in conjunction with ongong O&M
activities. We have several ideas for projects and are currently working on a
5 year marsh creation project at Island "H," a dredge material disposal island
near Wanchese, North Carolina. This project is a cooperative effort between the
Wilmington District, the Waterways Experiment Station (WES) and NMFS and involves
annual planting of Spartina alterniflora and ST) rtina patens for eductional
demonstration, shoreline erosion control and enhancement of fish habitat.
Although the first planting in 1992 was severely damaged by the March 13 Storm,
the second year's planting appeared to be surviving well this spring, and we are
optimistic about this year's work. The Corps and NMFS are scheduled to monitor
this site this October.
2) Coastal America - This is an interagency initiative to implement projects to
restore or enhance the coastal environment. The Corps has contributed hydrologic
analysis, planning and design assistance, for a Coastal America project, funded
by EPA, to remove obstructions to anadromous fish. The project involves the
removal of 2 dams. One is on the Neuse River near Goldsboro N. C. and one is on
a tributary and located near Cherry Hospital. Work is scheduled for the near
future.
3) Section 1135 of the Water Resources Development Act of 1986 - This authority
allows the Corps to modify existing projects for the improvement of the
environment. These projects require a nonfederal cost share partner. The Corps
are investigating three potential Section 1135 projects. These projects are all
in reconnaissance phase and include: Cape Fear River Locks and Dams - a project
to improve the passage of anadromous fish at Lock and Dam 1; Snows Cut - a
shoreline protection project on an AIWW land cut near Carolina Beach N.C.; and
Restoration of Tidal Creeks - projects to improve tidal flushing on three creeks
near Wilmington N.C..
4. Other Topics/Open Discussion. The only item discussed during this time was
with regard to the Colonial Waterbird Committee. It was suggested that the
Colonial Waterbird Committee hold their annual meeting next year immediately
after the dredging coordination meeting (and in the same location) since most
committee members would be in attendance for the dredging meeting. All
interested parties agreed that this was a good idea.
5. Actions Required. As a result of issues and questions raised during this
meeting the following actions are required:
a. Continued coordination between the Corps (Dan Small - POC) and the
Division of Water Resources and the North Carolina Division of Coastal Management
with regard to the new amendments to the Dredge and Fill Law and its implications
for the Corps. i
b. The Corps (Howard Varnam - POC) will investigate possible solutions to
the deterioration of sandbags (and associated erosion) at the Harkers island
disposal site.
C. The Corps (Trudy Wilder - POC) will make a decision regarding the
disposal of material at Wainwright Slough.
d. Coordination between the Corps (Trudy Wilder - POC) and the Colonial
Waterbird Committee regarding potential solutions to the erosion of Big Foot
Island.
e. The report on the impacts of dredged material disposal into SAV at
Walter Slough will be completed (Corps and NMFS) and shared with interested
agencies.
f. Continued construction of oyster reefs at Manteo (Shallowbag Bay) by
the Corps and NC Division of Marine Fisheries and continued monitoring of oyster
reef production.
g. Bill Adams (Corps POC) and the POCs listed in paragraph 2.h. will begin
work on determining better/more beneficial dredging windows.
h. Dan Small (Corps POC) will complete the EA on the nearshore berm
project at Morehead City.
i. The Corps (Carmine Forcinito and Phil Payonk - POCs) will coordinate
with appropriate agencies/ individuals on possible placement of buoys at the
WOFES.
j. The Corps will complete environmental work (FONSI and Public Notice)
for the AIWW, Section III, Tangents 2-6 (Trudy Wilder - POC).
k. Cape Fear River Above Wilmington - The Corps (Howard Varnam - POC) will
investigate the use of a sidecast dredge on this project and the Environmental
Resources Branch (Corps) will coordinate this with appropriate agencies.
6. Update. Two projects that were discussed during the dredging coordination
meeting will not be dredged in FY 95. They are the Alligator Pungo Land Cut and
the Channel from Back Sound to Lookout Bight. Recent hydrographic surveys
indicate that these two projects do not need to be dredged.

FY 95 DREDGING PROJECTS
* 1. ATLANTIC INTRACO STAL WATERWAY (ALLIGATOR PUNGO LAND
CUTI. (Plate 1)
Project Description. This maintenance work involves removal of material lying
above the plane of 14 feet mean low water (m.l.w.) along designated limits of the AIWW.
Routinely, the material has been placed along the toe-of-the-bank adjacent to the channel.
FY 95 maintenance will involve placing the material in upland diked disposal sites. Dredging
will be performed with a hydraulic pipeline dredge.
2. ATLANTIC INTRACOASTAL WATERWAY (AM INLET CROSSING.
(Plate 2)
Project Description. This routine maintenance dredging involves removal of all
material lying above the plane of 14 feet below m.l.w. within the designated limits of the
channel at various inlet crossings. The estimated quantity of material to be removed varies,
depending upon the areas to be dredged during the dredging cycle.. Dredging is to be
accomplished by a hydraulic pipeline dredge with disposal in upland disposal sites or along
the ocean beaches adjacent to the inlet crossings. Maintenance is scheduled to start in early
January 1995 and will require approximately 6 months to complete. Every effort will be
made to complete all beach disposal prior to 1 May or soon thereafter. The areas known to
require dredging at this time are:
Area To Be Dredged Estimated Quantities Disposal Area
(Cubic Yards)
CAPE FEAR - LITTLE RIVER REACH
- Shallotte Inlet Crossing 69,400 Ocean Isle Beach
- Lockwood Folly Inlet Crossing 42,000 Holden Beach
- Carolina Beach Inlet Crossing
- Mason Inlet Crossing
- Shinn Creek Crossing
- Bogue Inlet Crossing
- Topsail Inlet Crossing
- New River Inlet Crossing
- Bear Inlet to Brown Inlet
18,000 Carolina Beach
13,000 Wrightsville Beach
25,000 Upland Dike
30,000 Upland Dike
14,000 Topsail Beach
56,000 North Topsail
150,000 Onslow Beach
3. WILMINGTON HARBOR ANCHORAGE BASIN AND 38-FOOT PROJECT.
(Plate 3)
This routine maintenance dredging is scheduled to begin October 1994 and will take
approximately 4 months. The work consists of the removal of all material lying above the
plane of 40 feet below m.l.w. within the limits of the channels. The estimated quantity of
material to be removed from the Anchorage Basin, Between Channel, and Fourth East Jetty is
approximately 800,000 cubic yards. The type of material is predominately silt with lesser
amounts of sand. The frequency of dredging is once every year. The dredged material will
be placed in the Eagle Island upland disposal site.
For the 38-foot project, approximately 742,000 cubic yards of material will be
removed from Upper and Lower Midnight Channels, Lower Lilliput, Keg Island, Lower Big
Island, and Snows Marsh Channel. Dredged material will be placed in the Wilmington Ocean
Dredged Material Disposal Site offshore. This work will be accomplished by a bucket and
barge dredge.
* 4. Waterway Connecting Pamlico Sound and Beaufort Harbor-, Channel From Back
Sound to Lookout Bight, and Wainwright Slough. (Plates 4 and 5)
This routine maintenance dredging involves removal of all material lying above the
plane of 9 feet below m.l.w. within the designated limits of the channel. The estimated
quantity of material to be removed is approximately 200,000 cubic yards of predominately
medium-to-fine sand. Material will be placed on the 12-acre sandbagged disposal site within
Back Sound.
Routinely, the material dredged from Wainwright Channel has been placed at or near
the toe-of-the-bank on the channel side of Wainwright Island. However, this disposal activity
results in the material running back into the channel resulting in channel shoaling. Therefore,
in FY 95 the placement of material on the back side of the island will be investigated along
with other disposal alternatives. This work will be coordinated with the other agencies in
FY 95.
* 5. CAPE FEAR RIVER ABOVE WILMINGTON. (Plate 5)
Project Description. The work involves removal of shoals along the navigation
channel in the Cape Fear River from Wilmington upstream to Fayetteville, approximately
111 miles. The total estimated quantity of material to be removed from all reaches is
approximately 87,500 cubic yards. Dredging is performed by hydraulic pipeline dredge with
material being placed along the toe-of -the-bank annually and in upland diked disposal areas
once every 5 to 6 years. In FY 95 we will be investigating the possibility of performing the
work using a sidecast dredge with toe-of-the-bank disposal.

6. WILMINGTON HARBOR - OCEAN BAR CHANNEL. (Plate 6)
Project Description. This work involves providing the authorized project depth of 40
feet at m.l.w. for the Wilmington Harbor Ocean Bar Channel (Baldhead Shoal Channel).
Rock obstructions will be removed from the channel bottom seaward of the channel's
intersection with Smith Island Channel and proceeding seaward to the end of the channel
(about 5.8 miles at sea).
.
7. MO EHEAD CITY HARBOR OUTER HARBOR (OCEAN BAR CHANNEL)
(Plate 7)
Project Description. The Outer Harbor maintenance consists of maintenance of the
-45 foot outer bar channel (Range A). The total quantity of material to be dredged is
estimated to be approximately 2 million cubic yards. Dredged material from the Outer
Harbor maintenance deepening will be discharged in a placement site for an underwater
nearshore berm. The work is scheduled to be performed between December 1994 and March
1995 by hopper dredge.
8. M-ANTED OREGON INLET CHANNEL WMRSEC ION - MANTEO-
OREGON INLET-OLD HOUSE CHANNEL. (Plate 8)
Project Description. This routine maintenance dredging is scheduled to begin on or
around 15 January 1995 and will require approximately 90 days to complete. The quantity of
material to be removed is approximately 100,000 cubic yards of coarse-to-fine sand. The
work requires the removal of all material lying above the plane of 14 feet below m.l.w. The
work is performed annually. the work will be accomplished by hydraulic pipeline dredge
with disposal of dredged material on adjacent disposal islands using the control-of-effluent
method of disposal.
9, RO T INSON CHANNEL (HATTERAS INLET TO HATTERAS). (Plate 9)
Project Description. Maintenance dredging will be accomplished by hydraulic
pipeline dredge with disposal of approximately 20,000 yards of dredged material on the ocean
beach (Hatteras Island).
10. OREGON INLET (QCEAN BAR CHANNEL AND VICI MTY OF BONNER
BRIDGE). (Plate 10)
Project Description. This routine maintenance dredging involves the removal of all
material in the authorized channel to a depth of 14 feet below m.l.w. in miles 0 to 1.5 of the
channel from Manteo to Oregon Inlet, and 17 feet below m.l.w. along the ocean bar channel.
Environmental clearances have been received to perform routine maintenance dredging of the
3
ocean bar channel by an ocean-certified hydraulic pipeline dredge or hopper dredge with
direct pumpout of dredged material with discharge of dredged material on the Pea Island
National Wildlife Refuge or disposal offshore.
11. U.S. MILITARY OCEAN TERMINAL SUNNY POINT (MOT SUI. (Plate 11)
Project Description. This routine maintenance dredging which is ongoing involves
dredging of the facility's access channels, connecting channels, and navigation basins on the
Cape Fear River in Brunswick County, North Carolina, to an overall depth of 36 feet below
m.l.w. Dredging will be accomplished by a large volume clam bucket dredge. Materials
excavated by clam bucket dredge will be transported by scow or split hull barge and dumped
in the EPA approved Wilmington Harbor Ocean Dredged Material Disposal Site. Dredging
schedule is contingent on shoaling conditions which is expected to occur around May-June
1995.

MEMORANDUM FOR: All Participants
SUBJECT: FY 94 Dredging Coordination Meeting
10 Nov 93
1. The FY 94 Dredging Coordination Meeting was held in Wilmington, North
Carolina on 4 November 1993. The agenda for this meeting is included as
attachment 1, attendees are listed as attachment 2. Following is a synopsis of
topics discussed during the meeting and any follow-up actions which will be
required as a result of questions and discussion on the various topics.
2. Review of FY 94 O & M Projects.
Discussion on this topic was limited as most O & M dredging projects for FY
94 are performed annually. The only exception to this, for FY 94, is the
renourishment of Wrightsville Beach and Masonboro Island, which are scheduled to
be performed every 4 years.
3. Proiect/Study Updates.
a. Morehead City Harbor, Brandt Island Pump-out. Construction on this
project began on October 19, 1993. Currently, dredged material is being pumped
out of the Brandt Island disposal site and is being placed on Atlantic Beach.
Two items of concern were discussed regarding this topic:
1) Plastic - some of the plastic material, which lines the diked disposal
site was inadvertently pumped to the beach, however, the plastic was seen as it
was coming out of the pipe on the beach and was cleaned up immediately. A
representative of the Corps stated that in the future some material other than
plastic may be used, if possible, so this situatuation could be avoided.
2) Fine sediments - because of the location of the spillway and the area
where the dredge must enter the Brandt Island disposal site, fine sediments,
which accumulate near the spillway, were picked up by the dredge and pumped to
the beach. As the dredge moves further into the island the amount of fine
material should decrease and coarser material should be encountered. Discussion
followed regarding the possibility of managing the disposal area so that fine
sediments are avoided, however, it was stated that this would involve moving the
spillway to the back side of the island and this was proposed previously but
opposed by several State agencias.
b. Morehead City Harbor Deepening/Maintenance. Questions regarding the
quality of material from the harbor deepening, the method of disposal, and the
anticipated quantity of material from maintenance dredging of the deepened harbor
were raised. It was noted that the material, based on borings, is medium to
coarse sand and the material will be placed on the beach; some material will go
to Pine Knoll Shores and some to Fort Macon. Also, it is estimated that the
volume of maintenance material dredged from the deepened channel will be equal
to the volume dredged during maintenance of the harbor at its current dimensions.
C. Sandbagged Disposal Islands. The Corps is in the process of replacing
some of the sandbags on Island "H.", which were destroyed during the March 1993
storm. In addition, the Corps is sandbagging the island near old House Channel.
Although attendees were not asked for an immediate answer, they were asked to
think about the possibility of changing the current method of sandbagging. The
suggestion was made by the Corps to pump material onto the islands and then
sandbag them, rather that the current practice of sandbagging the island prior
to pumping material on the island. This method would contain the dredged
material more efficiently than the currently used method.
d. Island "H" Mitigation, Oyster Reef Construction and Manteo (Shallowbag
Bay) Project, O & M Mitigation, Disposal Islands. Construction of the Island "H"
mitigation oyster reef is complete. In addition to the Island "H" mitigation
site, there are 7 islands along the Oregon Inlet Channel which are used for
dredged material disposal and for every acre of shallow water bottom covered by
dredged material, 0.66 acres of oyster reef will be created by the Corps as a
means of mitigation. The North Carolina Division of Marine Fisheries will

monitor the oyster reef sites for 4 years and then the sites will be turned over
to them for management. Discussion followed regarding the lack of information
on the long-term productivity of these oyster reefs. Several agencies agreed
that a lack of data does exist, but stated that they did not have the resources
to do long-term monitoring of the reef sites. A suggestion was made to get local
university students to do reef studies as part of their graduate studies. The
Corps of Engineers and the NC Division of Marine Fisheries will follow-up by
coordinating on exploring the feasibility of initiating studies on this subject.
4. FY 93 Emergency-Dredging Activities.
a. Cape Fear River. The Corps removed a shoal in the Upper Midnight Channel
by renting equipment from a contractor who was in the area. Approximately 3000
to 4000 cubic yards of material were removed at total cost of $3000.
b. Oregon Inlet Dredging. The Corps just completed some dredging west of
the Oregon Inlet Bridge.
5. Other Topics/Open Discussion.
a. SAV Impact Assessment, Walter Slough Channel. Conclusions on the
covering of grass beds are forthcoming.
b. AIWW Long-term Study. The Corps is currently working on Phase I of this
study and the study will continue as funded. Phase I is an in-house document,
but will be available to. anyone interested in its content. A few questions were
raised regarding the long-term maintenance of the AIWW and topics which would be
included in the long-term study. It was stated that all issues in question would
be addressed in the long-term study.
C. Cape Fear River Colonial Nesting Waterbird Islands, and Others. The
technique of placing dredged material on these islands in the Cape Fear River was
very successful. Immediately following placement of dredged material, 3648 pairs
of royal terns nested on Ferry Slip Island. South Pelican Island was successful
as well. A few islands which are in need of material were discussed. These
include Wells Island, the island near Drum Inlet, Wainwright Island and Battery
Island. A representative of the Corps stated that placing material on some of
these islands was a possibility and would be considered.
d. Habitat Creation/Restoration/Coastal America Program. The Corps is
investigating possibilities for beneficial uses of the dredged material (rock)
that will be dredged from the Ocean Bar channel during the upcoming dredging,
which will attempt to deepen the channel to its authorized dimensions. Several
alternatives were discussed and numerous questions were raised regarding the
various alternatives. The majority of questions could not be answered without
further investigation, and it was decided that this subject should be discussed
in another forum where all interested parties, including commercial and
recreational fishermen, could be represented and questions raised could be
answered. The Corps will contact the resource agencies and arrange for the
necessary meetings regarding this subject.
e. Biological Studies of Beach Disposal Projects. Although some beach
monitoring is performed on beach disposal projects, detailed monitoring is not
done. There is a serious lack of information in the area of beach monitoring,
i.e. there are no established thresholds for monitoring. It was suggested that
a detailed literature search needs to be done to determine the "gaps" in the data
and then research needs to be carried out to fill these "gaps." It was also
suggested that any information gained regarding impacts of beach disposal should
be conveyed to the public. Questions were raised regarding funding and personnel
for the necessary research. It was again suggested that local university
students could perform some of the necessary work. This is a topic which will
require further coordination between all interested parties. The Corps will
follow-up by contacting the resource agencies and initiating plans to study the
impacts of beach disposal projects.
f. Report on Shortnose Sturgeon and Other Anadromous Fishes, Lower Cape Fear
River. The long-term study results are in regarding this topic and based on the
data it would be beneficial to change the dredging window for the Lower Cape Fear
River. The suggested change for the dreging window is from October 1 -March 31
to a new window of August 1 - January 31. Several agencies agreed with this
change, however, an official position has not yet been received from the National
Marine Fisheries Service. Further coordination on this subject will be required

and the Corps will initiate this coordination.
g. Project Modifications After Award of Dredging Contracts. Attendees were
informed that if a contractor proposes any changes to a project after award of
a contract, the contractor is generally required to acquire any clearances which
are necessary as a result of those changes. This procedure always applies to
those changes that are only to the benefit of the contractor (i.e. different
borrow area, new pipeline route, etc.). Changes that are made at the Corps
request or that have to be made because of changed conditions will be addressed
by the Corps.
h. Sea Turtle Nesting. Tom Henson, Wildlife Resources Commission, suggested
that sea turtle nesting data be looked at to determine if a change in the
dredging window (beach disposal) is warranted. If a change is warranted, the
Wildlife Resources Commission will initiate coordination between the Corps and
resource agencies to discuss possible changes.
h. Drum Inlet. The Corps is looking at the possibility of re-initiating
dredging in Drum Inlet. An Environmental Assessment will be circulated for
public review in FY 94.
6. As a result of issues and questions raised during this meeting the following
actions are required:
a. Further investigation by the Corps and interested agencies regarding the
method of sandbagging dredged material disposal islands. Howard Varnam (CESAW-
CO-N) will initiate this investigation if it is to be pursued.
b. Initiation by the Corps (Dan Small, PD-E) and the NC Division of Marine
Fisheries (Mike Marshall and Mike Street) of the feasibility of studies on long-
term productivity of oyster reefs.
C. Coordination between the Corps (Trudy Wilder, PD-E) and other agencies
regarding placement of dredged material on bird islands which are in need of
material.
d. Further research into the beneficial uses of rock which will be dredged
from the Cape Fear River Ocean Bar channel and coordination between the Corps,
interested agencies, and the public regarding possible alternatives. John Meshaw
(CESAW-PD-E) will initiate this research and coordination.
e. Frank Yelverton (CESAW-PD-E) will initiate coordination on the biological
studies of impacts of beach disposal.
f. Bill Adams (CESAW-PD-E) will continue to coordinate with resource
agencies on the change in the dredging window for the Lower Cape Fear River.
g. Study of sea turtle nesting data by Tom Henson a..d coordination regarding
a possible change in the dredging window for beach disposal.

1. ATLANTIC INTRACOASTAL WATERWAY NORFOLK (AIWW) TO SC LINE. (Plate 1)
Project Description. This routine maintenance work involves removal of
material lying above the plane of 14 feet mean low water (mlw) along
designated limits of the AIWW. Dredging is performed with a hydraulic
pipeline dredge with disposal of dredged material in diked upland disposal
sites along the channel. Dredging of the AIWW between Bear to Brown Inlet
is scheduled for this coming fall. Dredging will be performed under the
dredging contract for AIWW inlet crossings.
2. ATLANTIC INTRACOASTAL WATERWAY (AIWW) INLET CROSSINGS. (Plate 2)
Project Description. This routine maintenance dredging involves
removal of all material lying above the plane of 14 feet below mlw within
the designated limits of the channel at various inlet crossings. The
estimated quantity of material to be removed varies, depending upon the
areas to be dredged during the dredging cycle. Dredging is to be
accomplished by a hydraulic pipeline dredge with disposal in upland
disposal sites or along the ocean beaches adjacent to the inlet crossings.
Maintenance is scheduled to start in early January 1994 and will require
--approximately 6 months to-complete.

3. WILMINGTON HARBOR ANCHORAGE BASIN, 25-FOOT AND 38-FOOT PROJECT.
(Plate 3)
Project Description. This routine maintenance dredging is scheduled to
begin November 1993 and will be completed prior to March 31, 1994. The
work consists of the removal of all material lying above the plane of 40
feet below mean low water (mlw) within the limits of the channels. The
estimated quantity of material to be removed from the Anchorage Basin,
Between Channel and Fourth East Jetty is approximately 800,000 cubic yards.
The type of material is predominately silt with lesser amounts of sand.
The frequency of dredging is once every year. The dredged material will be
placed in the Eagle Island Upland disposal site.
Also to be dredged.at this time is approximately 30,000 cubic yards of
material from the 25-foot project turning Basin which is predominately fine
sand. This material will be placed in the Ideal Cement disposal area.
For the 38-foot project, approximately 370,000 cubic yards of material will
be removed from Upper Midnight Channel, Upper Lilliput, Keg Island, Lower
Brunswick, Upper Brunswick, and Lower Big Island. The material consists
mostly of fine sand and silt with lesser amounts of shell fragments. The
location of the upland disposal sites are shown on Plate plate 4. This
work will be accomplished by hydraulic pipeline dredge

6. WRIGHTSVILLE BEACH/MASONBORO ISLAND. (Plates 5A, 5B)
Project Description. The proposed action involves the renourishment of
Wrightsville Beach and performing sand bypassing of material to Masonboro
Island. Material will be obtained from existing sediment traps/borrow
sites in Masonboro Inlet and Banks Channel. The material is naturally
occurring coarse to fine sands. Due to limited availability of sand in
existing sediment traps, in 1994 Wrightsville beach will receive an
estimated volume of 594,000 cubic yards and Masonboro Island will receive
about 343,000 cubic yards. Renourishment of Wrightsville Beach is
scheduled to begin in mid-January 1994 and be completed by late April 1994,
bypassing of material to Masonboro Island is scheduled to begin in late
April 1994 and be completed by mid-July 1994.
7. MOREHEAD CITY (INNER HARBOR PROJECT). (Plate 6)
The proposed action involves disposal of dredged material on Bogue Banks
from maintenance dredging of Bulkhead Channel, the combined maintenance
dredging and deepening of the Morehead City inner harbor navigation
channels, and pumpout of the Brandt Island upland diked disposal site.
Dredging started October 18, 1993 and is scheduled completion date is March
15, 1994. This is a one-time action. An additional three months
(September - November) is needed beyond the regular disposal window in
order to have sufficient time to perform the different aspects of the work.
8. MOREHEAD CITY HARBOR OUTER HARBOR (OCEAN BAR CHANNEL). (Plate 7)
. Project--,Description. The Outer. harbor Deepening: _and. Outer harbor
a_ maintenance consists of: deepening the..outer harbor_,(Cutoff Channel) to -45
feet cl Epen^in?'-the -6hter,-bar charnel.(Range- A-)-.xto.,i-47,cifee-t--mlw from?::,42
feet mlw, and.adding wideners along the outer harbor range A channnel. The
outer harbor maintenance consists of removing the maintenance material in
the outer harbor to -40 feet mlw and in Range A to -42 feet mlw. The total
quantity of material to be dredged is estimated to be approximately
2,775,100 cubic yards. All dredged material from the outer harbor
maintenance deepening will be deposited in the designated Morehead City
Harbor Ocean Dredged Material Disposal Site. The work is scheduled to be
performed between December 1993 and March 1994 by hopper dredge.
9. MANTEO OREGON INLET CHANNEL (INTERSECTION - MANTEO-OREGON INLET-OLD
HOUSE CHANNEL) (Plate 8)
Project Description. This routine maintenance dredging is scheduled to
begin or or around January 15, 1994 and will require approximatley 90 days
to complete. The quantity of material to be removed is approximately
100,000 cubic yards of coarse to fine sand. The work requires the removal
of all material lying above the plane of 14 feet below mlw. The work is
performed annually. The work will be accomplished by hydraulic pipeline
dredge with disposal of dredged material on adjacent disposal islands using
the control of effluent method of disposal.

10. OREGON INLET (OCEAN BAR CHANNEL). (Plate 9)
Project Description. This routine maintenance dredging which is
currently being performed involves the removal of all material in the
authorized channel to a depth of 14 feet below mlw in miles 0 to 1.5 of the
channel from Manteo to Oregon Inlet, and 17 feet below mlw along the ocean
bar channel. Environmental clearances have been received to perform
routine maintenance dredging of the ocean bar channel by an ocean-certified
hydraulic pipeline dredge or hopper dredge with direct pumpout of dredged
material with discharge of dredged material on the Pea Island National
Wildlife Refuge. Work is currently performed with an ocean-certified
pipeline dredge.
11. CAPE FEAR ABOVE WILMINGTON. (Plate 10)
Project Description. The work involves removal of shoals along the
navigation channel in the Cape Fear River from Wilmington upstream to
Fayetteville,'approximately 111 miles. The total estimated quantity of
material to be removed from all reaches is approximately 87,500 cubic
yards. Dredging is performed by hydraulic pipeline dredge with material
being placed along the toe-of-the-bank annually and in upland diked
disposal areas once every 5 to 6 years. Dredging in FY 94 is contingent on
the availability of funds.
12. U.S. MILITARY OCEAN TERMINAL SUNNY POINT (MOTSU). (Plate 11)
Project Description. This routine maintenance involves dredging of the
facility s a-c-aes" =channels, connecting c}iannels;-and-navigation. basins on - f - -? r
the Cape Fear River in Brunswick County, NC, to an overall depth of 36 feet
below mlw. Dredging will be accomplished by a large volume clam bucket
dredge. Materials excavated by clam bucket dredge will be transported by
scow or split hull barge and dumped in the EPA approved Wilmington Harbor
Ocean Dredged Material Disposal Site. Dredging schedule is contingent on
shoaling conditions which is expected to occur around May-June.
NOTE: Funds for this FY do not allow a complete survey of projects. Other
projects may be scheduled as navigational surveys are performed or
unexpected shoals occur which require immediate removal. Should funds
become avaiable and projects are scheduled, notices will be made avaiable
to Federal and State resource agencies and the interested public.

ALTERNATIVES ANALYIS
CONSTRUCTION OF SANDBAG DISPOSAL ISLAND
OLD HOUSE CHANNEL, DARE COUNTY, NORTH CAROLINA
A. Project Description. The sandbag retention island will be located
approximately 1.5 miles from the junction of Old House Channel and Oregon
Inlet Channel (figure 1). Construction of the sandbag dredged material
disposal island is needed in order to accommodate disposal of dredged material
from maintenance dredging of Old House Channel between Island MN (006-08) to
the north and the sandbag disposal island (Wells Island - 006-35) located
approximately 2.0 miles south of the junction. Wells Island was constructed
in 1988.
Construction of the 12-acre sandbag retention dike is scheduled for
the summer of 1993 and is expected to take approximately 1 to 2 months to
construct. The project is being coordinated with the National Marine
Fisheries Service, Beaufort Marine Laboratory, to further document whether
submerged grassbeds are in the area. Based on initial review of aerial
photography, there appears to be no submerged grassbeds located within the
general area of the proposed construction site.
Once the sandbag retention dike is constructed, dredged material from
maintenance dredging of Old House Channel will be placed within the confines
of the dike to construct the island. Dredged material from routine mainte-
nance dredging will be placed on the island using the control of effluent
method of disposal (i.e., allowing the effluent to flow back toward the
channel being dredged).

upon request.
Approximately 4,000 cubic yards of predominantly fine to medium sand will
be excavated from the bottom in the vicinity of the construction site for the
filling of the nylon sandbags. The sand source is free from toxic material.
B. Environmental Documentation. The use of sandbag dredged material
disposal islands along Old House Channel is described in the Final
Environmental Impact Statement and the Final Supplement to the Environmental
Impact Statement for Manteo (Shallowbag) Bay Project, Dare County, North
Carolina, filed with the U.S. Environmental Protection Agency on April 29,
1979, and November 7, 1980, respectively. State Consistency concurrence
was received on September 19, 1980, for the Manteo (Shallowbag) Bay project,
which includes Old House Channel. A Section 404(b)(1) Evaluation (Public Law
95-217), dated December 12, 1977, was prepared for underwater sand filled bag
retention works associated with construction of disposal islands along Old
House Channel. Use of sandbag dredged material disposal islands as part of
the dredged material disposal plan for the Manteo (Shallowbag) Bay project
was approved prior to passage of the Clean Water Act (December 7, 1977). A
Section 401 Water Quality certification was requested from the North Carolina
Division of Environmental Management on February 5, 1993, to cover construc-
tion of the sandbag retention dike. A Public Notice describing the proposed
project will be prepared and circulated to Federal and State agencies and the
interested public prior to construction.
C. Alternatives. Dredged material disposal islands along Oregon
Inlet-Old House Channel are managed for colonially nesting waterbirds.
Material is scheduled for placement on the islands when feasible in order
to provide suitable habitat for pioneering bird species (i.e., birds pre-
ferring mounded bare sand with little if any vegetation). Dredged material
from maintenance dredging of Old House Channel is routinely placed on Islands
L (006-02) and MN. Elevations on these islands have reached a point where
wind borne sand is becoming a major problem for habitat management. For
bird management purposes, normal elevation of these islands should not
exceed 15 feet in height, since the higher the islands project upward into
the coastal winds the .greater the likelihood of nesting failure due to nest
covering by shifting winds. Islands L and MN have already reached elevations
close to 15 feet.
Disposal islands along the channel are expanding into the surrounding
sound at a rapid rate along the nonchannel sides due to sand migration off of
the island. Any increases in the size of the islands enhances the likelihood
that predatory mammals can be sustained and become permanently established.
Placing additional sand on the islands would only exacerbate the problems
currently-being expefienced.
a?=s?a- aty=of -=pumping,=mai-n-tenancA.-r.&,edg..ed=-mater a .ath J d; -- :.
material disposal islands along Oregon Inlet-Old House Channel has been
investigated as a possible alternative to construction of the sandbag island.
The District has agreed not to dispose on Island MN unless prior approval has
been obtained, because the island serves as a nesting area for brown pelicans.
Operational constraints due to the pumping distance to Island L which is the
nearest disposal island to'the section of channel to be dredged (3-4 miles
maximum) limits the feasibility of this being a long-term management option
for the disposal of dredged material from the channel.
D. Mitigation Plan. Construction of the second sandbag island is part of
the operation and maintenance plan of the existing Manteo (Shallowbag) Bay
project. The sandbag retention dike will cover approximately 12 acres of
estuarine bottom in Pamlico Sound. The raising of estuarine bottom and any
associated mitigation is done in accordance with the U.S. Fish and Wildlife
Service Mitigation and Enhancement Plan dated August 21, 1980, for the Manteo
(Shallowbag) Bay project. The mitigation plan for the expansion and
maintenance of the Manteo (Shallowbag) Bay project requires that 0.66 acres
of oyster reefs be constructed for every acre of estuarine bottom raised above
mean high water. Funding of any mitigation is a Federal responsibility. Site
selection, construction, and maintenance of oyster reefs will be done through
a Memorandum of Agreement between the U.S. Army Corps of Engineers, Wilmington
District, and the North Carolina Division of Marine Fisheries, Shellfish
Rehabilitation Program.
The District has done a preliminary assessment of the total number of
acres of estaurine bottom raised from maintenance dredging since 1977 as a
result of the use of dredged material disposal islands along Old House Channel
and Oregon Inlet Channel. Attachment 1 shows the total number of acres of
estaurine bottom raised per island since 1977, based on planimetering work
done by the District using aerial photography taken in 1990. Through a
previous agreement with the State, only those acreages of estaurine bottom
raised as a result of disposal of maintenance dredged material on these
islands since 1977 will require mitigation. The acreages raised by the first
sandbag island in 1988 (Wells Island) is shown on attachment 1. The acreages
raised by the construction of the second sandbag island this summer will be
included in the overall number of acres of estaurine bottom shown on
attachment 1. Currently, the North Carolina Division of Marine Fisheries,
Shellfish Rehabilitation Program, is implementing the mitgation plan for the
recent expansion work associated with Island H. Construction of the oyster
reefs near Wanchese should be completed by the end of this year. At this
time, we recommend that this work be completed prior to any further mitigation
work in order that any. experiences learned can be incorporated in future
plans.

MEMORANDUM
TO: Mike Marshall
FROM: Jeff FrenchZ=-O?
DATE: October 4, 1993
SUBJECT: NCDMF/US Army Corps.
On September 2, 1993 the crew of the R/V SHELL POINT completed
cultch planting operations for 1993 at Half Moon Rock, in Roanoke
Sound, Dare County. A total of 30,050 bushels of cultch material
were placed at Half Moon Rock during 1993 in response to your
instructions concerning estuarine bottom mitigation relating to US
Army Corps of Engineers activities in the area.
The following table details the cultch material composition of
each of the planting site established during this project.

Planting site No. 843 was established to the south of site No.
802 in the Half Moon Rock area of Roanoke Sound. Calico scallop
shells and marl (fossil stone) were used to complete the 1993
planting due to a shortage of available surf clam material. Both
marl and calicos are regularly utilized as cultch material within
our program and should prove as equally effective as surf clam
,, -shell in that area. The planting sites were established on flat
r sandy bottom at an average depth of 5 feet.

Sampling of oyster larvae (or "Spat") found on cultch material
planted during 1992 has,been completed by our staff. Both planting
sites No. 802 and No. 803 were found to contain an average spatset
of 0.67 oyster larvae per piece of cultch. This is generally
considered a moderate level spatset with 1.0 or above considered as
good.
The locations of all three cultch planting sites discussed
herein are made available to the public. Loran bearings are listed

SCHWEIZER, Oregon Inlet
BAR CHANNEL: Schweizer presently working Bar Channel. Users are complaining
that Contract Dredge tried to realign present channel and worked primarily outside of
the red buoys. RECOMMEND: Beaufort survey channel and notify Coast Guard of
need to relocate buoys.
NO. 33: The area surrounding No. 33 is in fair shape at the present time. The fall
fishing has not fully started, and have a minimum number of transits at this time.
RECOMMEND: Extend necessary permits to allow for minimal dredging during the
winter to insure channel dimensions are maintained.
NO.45: It appears the fishing fleet is having problems in the area of No. 45. Several
vessels have radioed the SCHWEIZER and stated the need for dredging in this area.
RECOMMEND: Survey area, and determine need for dredging. If SCHWEIZER can
be used in this area, pursue necessary permits.
