8. PROJECT SUMMARY: Carteret County is proposing to maintenance excavate Atlantic
Harbor and place spoils in the White Point area. Atlantic Harbor is a federal harbor.
Additionally, Carteret County is proposing to stabilize White Point with a rock sill and
living shoreline.
9. NARRATIVE DESCRIPTION: The Atlantic Harbor project is located in Core Sound in
the community of Atlantic, Carteret County. The existing harbor and federal channel is at
the end of Seashore Dr. in Atlantic. This harbor is managed by the Carteret Co. harbor
authority.
Atlantic Harbor is an existing federal harbor and is accessed off of Core Sound by a federal
channel. Within the harbor is an existing docking facility mostly used by commercial
vessels. Atlantic Harbor was constructed in 1972. The channel was last excavated in 2018
under General Permit #71340C. The current low water depth in the basin is -3' and -4.5' in
the basin. Aerial photography does not indicate the presence of SAV. Adjacent to the access
channel is White Point. This area is partially stabilized by older sand bags.
This area of Core Sound is classified as SA-ORW by DWR. It is not a Primary Nursery
area. It is closed to the harvesting of shellfish. Carteret County's Land Use Plan classifies
the future land use of this area as community.
10. PROJECT DESCRIPTION: Carteret County is proposing to maintenance excavate
Atlantic Harbor and the associated access channel in an effort to restore navigation for
recreational boating and commercial fishing vessels. The excavation would be performed
by bucket to barge with spoils being placed on White Point immediately adjacent to the
harbor. White Point would be stabilized using a combination of living shoreline and granite
sill.
The proposed cut in the access channel would be 1,900' long and 40' wide. Water depth in
this area would increase from -3' MLLW to -6' MLLW. A total of 10,750yd3 would be
excavated from the access channel. The proposed cut in the basin would be 700' long and
190' Wide. Water depth in this area would increase from -4.5' MLLW to -5' MLLW. A
total of 2,500yd3 would be excavated from the basin. Connecting water depths range from
-6' to -8' at Normal Low Water. The excavated material would be placed on White Point
directly adjacent to the access channel.
Carteret County also proposes to stabilize White Point with a combination granite sill and
living shoreline. The granite sill would be 1,885' long and range in width from 4'-28'
depending on the portion of shoreline. The structure will extend a maximum of 33'
waterward of NHW. The structure will be backfilled with 300yd3 of dried dredge spoil to
cover 20,706ft2. The backfill area will be planted with Coastal Wetland plants in association
with NC Coastal Federation. The consultant(Moffatt & Nichol) has provided a detailed
narrative in order to help in the review of this project.
11. Anticipated Impacts: This project should increase navigation of the area by recreational
boaters and provide a deeper channel for commercial fishing vessels to safely ingress and
egress. There would be 4.86ac ac of EW and PTA excavated and .5ac of EW and PTA

filled during this project. There would be 2.74ac of high ground filled. Temporary
turbidity could occur during excavation and construction of the living shoreline.

Atlantic Harbor Maintenance Dredging & Living Shoreline
Permit Narrative
Project Purpose, Need & Scope
Carteret County (County) is requesting federal and state authorization to conduct maintenance dredging
within the entrance channel and inner harbor of Atlantic Harbor of Refuge. The project will also construct
a 1,735 linear foot (If) granite rock sill supplemented by six (6) 25-1f engineered wave attenuators (total
length 1,885 If). The rock sill and wave attenuators will provide shoreline stabilization for White Point
peninsula and marsh habitat restoration. A maximum of approximately 13,250 CY of material will dredged
from Atlantic Harbor and placed on the White Point material placement area. Nominal size rock weighing
between 350-lbs (18" diameter) and 900-lbs (24" diameter) will be placed to construct the 1,7351f rock sill.
An estimated 8,030 tons of granite rock will form the marsh sill with an additional 1,550 tons of Class A
granite riprap used as bedding stone. Engineered wave attenuators will also be installed in 25-ft segments
fronting breaks in the rock sill. The 15-ft breaks will enable fish passage and tidal flushing landward of the
sill.
The Atlantic Harbor of Refuge, authorized under Section 107 of the River and Harbor Act of 1960, was
constructed in 1972. The harbor is in the unincorporated community of Atlantic in Carteret
County and situated off Core Sound 3 miles west of Ophelia Inlet. Figure 1 shows the Atlantic Harbor
vicinity in planview. The harbor is important to the local fishing industry as a place of safety, and access to
the Atlantic Ocean. As such, the harbor facilitates a vital component contributing towards the continued
longevity of the local community.

The Atlantic Harbor of Refuge is a federally -authorized project that has been historically maintained by the
USAGE; however, the USACE has experienced difficulty in dredging the harbor recently due to the lack
of an upland material placement facility. The Wilmington District (SAW) notified Carteret County of the
maintenance difficulties in June of 2017 and requested the County take actions to construct a placement
facility and potentially dredge the harbor'. Tab E (pertinent correspondence) provides the correspondence

Carteret County Navigation Project
Atlantic Harbor Maintenance Dredging & Living Shoreline
Permit Narrative
detailing the lack of a material placement area to receive the dredge spoil. In response to the USACE's
notification, Carteret County has secured a material placement facility and intends to maintenance dredge
the inner harbor of refuge and entrance channel. The County will also construct a granite rock sill to provide
shoreline stabilization and enhance marsh habitat restoration.
The maintenance work will remove approximately 13,250 cubic yards (CY) of silty material from the
proposed work areas as shown in Tab F (permit drawings). The maintenance work maintains consistency
with the federal authorization for Atlantic Harbor and provides a maximum 40-ft channel at elevation -6-ft
MLLW +1 through the harbor entrance. The template also generally maintains a 5H:1V sideslope to
discourage additional sediment sloughing from the adjacent area. Within the harbor entrance, the side slopes
increase to a 3H:1 V to minimize the dredging footprint. The proposed channel width and depth also reduces
within the harbor entrance to a minimum width of 16-ft at elevation -5-ft MLLW +1. Inside the harbor, the
maintenance template maximizes the dredging potential by expanding to approximately 190-ft wide with
5H:1 V side slopes. However, the template maintains the maximum dredge depth of -5-ft MLLW +1 as
proposed for the entrance channel. Tab F (permit drawings) provides additional details describing the
maintenance template.
An emergency maintenance dredging project along the entrance of Atlantic Harbor was permitted (GP-
71340) and conducted in the summer of 2018 to provide short-term relief of the shoaling impacts. This
maintenance dredging project removed approximately 1,000 cubic yards (CY) to create a narrow channel
through a heavily shoaled area immediately outside of the harbor entrance. Tab G (Previous Permits)
provides a copy of permit GP-71340 for reference. The County now intends to conduct a more extensive
maintenance operation to provide a long-term solution for the local navigation needs. Additional
maintenance projects have been conducted by the USACE since 1948. The original dredging of Atlantic
Harbor removed and estimated 78,150 CY in 1945 and six (6) maintenance events since have removed over
98,270 CY. Table 1 shows the maintenance history of Atlantic Harbor between 1948 and 19682.

shows elevations within the harbor entrance of -2 to -4 feet MLLW. Inside the harbor, elevations range
between -4-ft and -6-ft MLLW. Therefore, the County is proposing maintenance dredging to restore
navigational access and preserve the harbor of refuge status.

Permit Narrative
Sediment Compatibility
To support development of a dredging plan and associated permitting, sediment cores from Atlantic Harbor
were collected and tested in March 2018. Based on review of the analysis for geotechnical vibracore
samples the dredge material is considered non -beach compatible and will be placed in an upland placement
facility on nearby White Point. Tab I (Geotechnical Analysis) provides the geotechnical analysis of the
dredge material. The USACE designated White Point as a material placement facility and protective
breakwater for the harbor of refuge and entrance channel2.
In addition to the geotechnical analysis, five sites were sampled for chemical analysis beginning inside the
harbor entrance and extending southwest along the existing channel. Chemical analysis on the core
composites was conducted in accordance with the USACE guidance, Sediment Testing Guidelines for
Dredged Material Proposed for Disposal in Federal Project Disposal Areas by Applicants, along with other
screening guidelines. Tab J (Chemical Analysis) provides the chemical analysis for the Atlantic Harbor
samples.
A risk assessment incorporated the chemical analysis results and showed some parameters exceeded
selected screening levels. These included concentrations of certain metals, semi -volatile organic
compounds, and pesticides within the harbor and near the entrance. Additional testing outside of the harbor
showed decreased levels of these same contaminants. Semi volatile organic data for these stations were
primarily non -detect or below the reporting limit and there were no exceedances of the screening levels.
For metals outside the harbor, there were limited elevated concentrations (i.e., total chromium and
manganese).
Since there were some elevated concentrations of certain contaminants based on the screening results,
further analysis of the cumulative effects of multiple contaminants entailed using a risk calculator
developed by the Division of Waste Management (DWM). Designed to evaluate multiple exposure routes
associated with contaminated environmental media, the calculator estimates the risks associated with
current or potential future human exposure. The risk calculator incorporates the sediment core data from
three sites representing the areas to be dredged that were selected in consultation with DWM staff.
Application of the risk tool showed potential risk associated with arsenic and chromium for all three sites
with the addition of thallium for one site. However, the cumulative risks under the User Defined receptor
covering periodic use for a recreator and a trespasser on the island do not exceed the benchmark
assumptions in the tool. Further, chemicals like arsenic, chromium, and thallium have natural and common
anthropogenic sources that are likely influencing the results at these stations. The Resident receptor is not
applicable in these cases because, the dredge disposal site, White Point, does not have residential
development. In addition, Carteret County intends to file a deed stipulation disallowing any future
residential development on the property. A copy of the recorded deed restriction shall be provided to DCM
prior to the commencement of the dredging activities. In summary, the results demonstrate that disposal of
the dredge material on White Point should not pose a significant risk to human health or water quality. Tab
K (Risk Assessment) shows the risk calculations for the dredge material.
Construction Methodology
The project entails two (2) phases of work referenced as maintenance dredging and living shoreline. The
maintenance dredging will be conducted first to minimize the potential for impacts to the living shoreline
and to provide sufficient fill material to grade the marsh restoration area. An additional 300-CY will be

Permit Narrative
necessary to fill the marsh restoration area above the excavation volume required to place the rock sill.
Construction of the rock sill may begin prior to completion of the maintenance dredging, but an access way
will be maintained for transporting the dredge material to the placement site.
Maintenance Dredging
Approximately 13,250-CY of dredge spoil will be directly placed in the White Point material placement
area shown on Figure 2. Dredging operations will be conducted by a bucket dredge/excavator between
November 16 and March 31 in efforts to minimize the potential for environmental impacts. Dredging
activities will extend through day light hours but will not entail night time operations. Material will be
dredged from the Atlantic Harbor channel and placed on a barge or other floating work plant. A turbidity
control barrier will be utilized and remain until sediment in the water column has settled. The material will
be transported to the disposal site on White Point. A backhoe or excavator will move the material from the
barge to a truck or other hauling equipment on White Point where it will be placed and contained within an
earthen berm.
The ownership of White Point has not been determined and remains in question. Ownership could
potentially fall to either the adjacent property owner, Carteret County, or the State of North Carolina. White
Point formed from dredge material placement conducted with public funds, which suggest the site would
be publically owned. However, White Point is attached to the adjacent property and therefore could also be
considered as accreted lands. To resolve this issue, Carteret County has secured an easement from the
adjacent property owner for construction and maintenance of the project. Tab L (White Point Use
Easement) shows the easement letter provided as authorization to use the site.
Figure 2. Material Disposal Site (White Point)
The dredged material will be dewatered and placed within the upland disposal site with the intent of
permanent storage. Earthen berms or silt screens will be used to prohibit the effluent waters from reentering
the adjacent water bodies. In addition, turbidity curtains will be maintained surrounding the offloading site
4

Carteret County Navigation Project
Atlantic Harbor Maintenance Dredging & Living Shoreline
Permit Narrative
during times of dredging activities. The curtains will be positioned to capture any sediment disposition
spilling from the construction process.
Prior to placement of dredge spoils, the spoil containment basin and berms /silt screens will be inspected to
ensure the effectiveness and capacity to contain the material. The Division of Coastal Management (DCM)
will be notified so a representative may inspect the site to help verify the appropriate BMPs have been
established to help control the dredge effluent and material run-off. In addition, DCM will be notified
immediately in the unlikely event of containment breech.
Livine Shoreline & Marsh Restoration
Construction of the living shoreline and marsh restoration will entail placement of approximately 8,030
tons of 18-inch to 24-inch granite rock supported by approximately 1,550 tons of Class A riprap as bedding
stone. Filter fabric will also be placed beneath the bedding stone to provide additional protection against
settlement. The granite rock will function as a sill to tamper wave action and help stabilize the subtidal and
supratidal habitat abutting the structure. Approximately 40,000-ft2 of subgrade will be shaped to establish
a marsh planting area comprised of smooth cord grass (Spartina alterniflora) and saltwater cordgrass
(Spartina patens) will be planted to help enhance the shoreline stability and habitat function. Additional
vegetation suitable to the project conditions may also be planted as part of the restoration efforts.
Placement of the granite rock sill and vegetation will occur outside of the dredge material placement area
to reduce the potential for spreading or material run-off. The rock sill will generally be placed below
MLLW. Along the interior of White Point, from station 0+00 to station 4+25 as shown in Tab F (permit
drawings), the rock sill will be placed at elevation -1.5 MLLW with approximately 0.5-ft of bedding stone
placed beneath. From approximately station 4+25 to station 17+35, granite rock weighing an average of
350-lbs (I8-inch)will comprise the first 425-1f of the reef along the interior of White Point. Rock weighing
an average of 900-lbs (24-inch) will comprise the remaining 1,310-1f. The 24-inch nominal diameter rock
will be installed at elevation -2.5 MLLW and will also have 6-inches of bedding stone and filter cloth
underneath to help prevent settlement. Fifteen (15) foot gaps will be spaced every 200 linear feet to allow
flushing and fish passage landward of the sill. Large voids, created through use of non -varied rock sizes,
will also allow fish passage and flushing throughout the sill structure.
Approximately 3,000 CY of material will be excavated from within the proposed footprint of the sill to
install the granite rock and filter cloth. This material will be redistributed immediately landward of the sill
as backfill. The backfill will help create the marsh restoration area from approximately the MLLW elevation
to +2 MLLW. An estimated additional 300 CY of dredge material will be needed to complete the grading
and backfill proposed for the marsh restoration area. The marsh area will also be planted with approximately
75,200 spartina type plugs on approximate 9-inch center spacing. The marsh habitat and rock sill will
provide stabilization to the White Point shoreline and enhance the habitat function.
The granite rock will most likely be trucked to the site and placed by land based heavy equipment. Surveys
will be used to verify the placement locations and quantities along with load tickets from the approved
quarry. The attenuators will most likely also be constructed by land based equipment; however, water based
installation may be implemented at the contractor's discretion. Piles will be driven at approximate 4-ft
centers to support concrete disks infused with shell. The disks will be installed over the piles to form a wave
break. Tidal currents will be allowed and encouraged landward of the wave attenuator to promote flushing
behind the rock sill.

Carteret County Navigation Project
Atlantic Harbor Maintenance Dredging & Living Shoreline
Permit Narrative
Environmental Concerns
Based on meetings with regulatory agencies in December 2017 and 2018, the anticipated major regulatory
requirements include 408 Review through the USACE Civil Works branch, a Coastal Area Management
Act (CAMA) major permit, and USACE General Permit (GP) 2878. The GP 2878 is issued by the USACE
Wilmington District "to authorize maintenance dredging within federally authorized navigation channels
and borrow areas, and the discharges of excavated and/or fill material within federally approved confined
upland disposal areas or, in the case of beach quality sand, federally authorized beach retention areas or
federally authorized beach nourishment project areas in the state of North Carolina."
Additional input from the resource agencies indicated no Biological Assessment for protected species nor
a SAV survey would be required. However, as a supplemental resource for the permit review, Tab M
(Atlantic Harbor Environmental Statement) provides the 1976 document evaluating maintenance dredging
of Atlantic Harbor, along with other waterways connecting Pamlico Sound and Beaufort Harbor. The
Wilmington District USACE authored the 1976 document.
Also, as previously stated, dredging activities will be restricted to November 16 through March 31 for
additional protection towards potential impacts. The cooler months generally offer a lower risk for
environmental impact.
Historic Resources
An archaeological assessment has not been completed for the proposed dredging; however, the site is a
federally authorized navigation channel and has been dredged since the 1940's.
North Carolina Environmental Policy Act (SEPA)
The project involves expenditure of public funds and is in compliance with the North Carolina
Environmental Policy Act (SEPA).
SEPA applies for any project that meets all three of the following criteria, an environmental document must
be prepared:
1. An expenditure of $10 million in funds provided by the state of North Carolina for a single project
or action or related group of projects or action
Or
land -disturbing activity of equal to or greater than 10 acres of public lands resulting in substantial,
permanent changes in the natural cover or topography of those lands (or waters)
2. An action by a state agency, and
3. Has a potential detrimental environmental effect upon natural resources, public health and safety,
natural beauty, or historical or cultural elements, of the state's common inheritance.
Since the project is less than $10 million and disturbs less than 10 acres of public land, further
environmental documentation under SEPA is not required.
Summary
The County is requesting state and federal authorization to conduct maintenance dredging of Atlantic
Harbor to aid navigation and preserve the health and safety of local boaters. A total of approximately
13,250-CY will be dredged and placed in the White Point material placement area, immediately adjacent
to the harbor of refuge. The proposed maintenance dredging will restore the channel to depths in the inner
M

Permit Narrative
and outer harbor to -5-ft MLLW +1 to -6-ft MLLW +1 inclusive of a 1-ft overdredge tolerance. The County
also proposes a granite rock sill to help protect and stabilize the White Point placement area. The rock sill
will be supplemented by pile supported concrete disk wave attenuators to further prohibit wave propagation
into the material placement area. Marsh restoration efforts will also be conducted landward of the rock sill
to promote vegetation growth.
The dredge material will be placed a minimum of 30-ft landward of the MHW line or landward of the marsh
restoration area, whichever is more restrictive. Dredge material placement will not exceed 3.5-ft above the
existing grade, or elevation +7.5 MLLW. Silt fencing shall be installed around the placement area, and shall
be maintained for the duration of construction. Turbidity curtains shall also be installed around the dredge
area to prevent the spreading of fines from the dredge sediment.
Sediment analysis of the dredge material indicated the presence of some contaminants. However,
consultation with DWM confirmed the material should not create a risk to nearby residents nor temporary
visitors to the island. In order to further limit the potential for impacts from the dredge material, Carteret
County will restrict residential development from occurring on the White Point Peninsula. Carteret County
will provide this deed restriction as a pre -construction requirement for the maintenance operations.
The granite rock sill proposed to surround the material placement area will limit the wave impacts and
erosion to the White Point peninsula. The sill will provide breaks supplemented by wave attenuators to
allow tidal flushing and fish passage. Marsh grass plantings will also be installed landward of the sill
between MLLW and elevation +2.0 MLLW.
The proposed work maintains consistency with the federally authorized channel for Atlantic Harbor,
including the federal development set -back line established along the White Point shoreline. The proposed
dredging remains within the authorized limits of the federal channel and the granite rock sill does not
encroach upon the development set -back line.
Carteret County intends to provide a long-term dredge material management site for the prolonged use of
maintaining the Atlantic Harbor of Refuge and entrance channel. The County understands the
environmental concerns associated with this project and has worked to provide minimization measures to
allow a successful and complete project. These efforts include coordination efforts with state and federal
resource agencies to identify potential concerns and also minimizing the construction window to the cooler
winter months of November through March. The project also maintains consistency with the State
Environmental Policy Act (SEPA). The overall project should provide a substantial benefit to the longevity
of Atlantic Harbor and the surrounding community.

Dear Mr. Burns,
Earlier this year, the U.S. Army Corps of Engineers received emergency supplemental funding for the
Waterway Connecting Pamlico Sound to Beaufort Harbor, NC, shallow draft navigation project which
includes the Atlantic Harbor of Refuge and Channels. We are currently working to include Atlantic
Harbor ranges one and two (see enclosed map) where this portion of the channel contains predominately
sandy material that is of a quality that is acceptable for placement on New Dump Island, as it has been
placed in the past. Subject to receiving acceptable bids, we anticipate that this portion of the Waterway
project would be included into an upcoming maintenance dredging contract scheduled for award in
August 2017, including areas in the Manteo (Shallowbag) Bay, Silver Lake Harbor and Rollinson
Channel.
At this time, we are unable to include the Atlantic Harbor of Refuge ranges one, two, three and to the
harbor of refuge, which include predominately non -silty material and require an upland disposal area.
Given that there are no upland disposal areas available at this time for placement of this type of material,
the Corps is unable to perform maintenance dredging and include these areas into this contract. Per the
requirements set forth in the construction of the harbor with an authorized depth of 7 feet for this project
built in the 1960s, the responsibility for providing lands, easements, rights -of -way, and disposal areas
including construction of these facilities lies with the non -Federal sponsor, Carteret County.
The Corps suggests that the county consider taking actions in the future to construct a disposal area for
silty material and potentially take actions to perform maintenance dredging of this area in conjunction
with the upcoming Corps contractual efforts. By the way, the Corps is using available Federal funds to
obtain updated geotechnical sampling and testing of the Atlantic Harbor of Refuge ranges one, two, three
and to the harbor of refuge, and hydrographic surveys of the entire project, which we will provide to you
once this information is available, likely within the next 3 to 4 months.
Please do not hesitate to contact me at [phone] or at jai es.m.medIock(cr;usace.army.miI if I can
help you further.
