CHECKLIST OF ADDITIONAL INFORMATION AND RECOMMENDATIONS FOR
PROCESSING APPLICATION
1. On the MP-1 form, please correct the following fields:
• 3.a. should indicate the Lumber River basin
• 4.b. describes 31.5 acres of proposed beach fill- yet figures given elsewhere seem to
indicate 32.8 acres of All. Please check and confirm this entry.
• 4.m. indicates there are no wetlands on site, yet there are coastal wetlands adjacent to
Eastern Channel.
• 61 only lists 3 adjacent riparian property owners- when 4 adjacent riparian' property
owners should be listed and notified. Additionally, please submit certified mail
receipts and/or signed green cards to show proof of adjacent riparian property owner
notification.
2. On the MP-2 form, please complete or correct the following fields:
• Add the length and width of the proposed channel dredging in the table
• Prease submit a letter of acceptance for the use of Sheep Island as an authorized
disposal site.
Please submit a complete signed and dated AEC Hazard Notice. A completed notice is
attached - please have Mi. Foster initial and 'date next to the long-term erosion rate, 100-year
storm recession calculation and flood elevations.
4. Please include more details on the design and dimensions of the proposed channel
excavation in your narrative. Additionally, the plans appear to show insufficient capacity
within the diked disposal site. Is additional work proposed to increase capacity? If so, this
work should be,shown on the plans; If not, please explain how material will be adequately
contained. Additionally, vibracore 9 was only taken to -14' NAVD 88, yet dredging appears
to be proposed to -15' NAVD in this area. Please note that per 07H .0312(4)(a); sediment
excavation' depths for all borrow sites shall not exceed the maximum depth of core at each
coring location"and that excavation may need to be limited to -14' in this area:
Please ensure your plans show all the following features: mean high water (MHW) and
mean low water(MLW) lines, waterward limits of coastal wetlands, existing structures
(including docks and sandbags), existing dunes, names of all adjacent riparian property
owners outside the project limits. Sheet 22 should also include the existing sandbags and
proposed work relative to.the,bags. Please adjust the weight of the MHW line on Sheet so
it is distinguishable from the other lines. Please also identify water depths/elevations on the
contour lines shown on Sheet 6 (Dredging Plan 1 of 7) Please ensure the scale indicated on
plans is accurate for the sheet size. Again, plans appear to show that there is insufficient
capacity within the diked area at Sheep Island to adequately contain the proposed dredged
material. Details of the water control structure and both pipe locations should also be shown
on the spoil site plans. Please contact me to set up a site visit to the spoil site. It is also
suggested that plans be enlarged to 1.1" x IT' sheets and aerial imagery be included on
channel dredging plans in order to better read them.

b. Give a brief description of purpose, use, and daily operations of the project when complete.
The purpose and need for the restoration project is driven by (1) commercial and recreational navigation requirements, (2)
estuarine 8 riverine water quality degradation, and (3) coastal erosion, which is currently rendering infrastructure vulnerable
and creating habitat loss for turtle nesting. Currently, the navigation of Eastern Channel, a natural channel, is limited to high
tides and many areas within the channel have severely shoaled to -4 ft to -6 ft NAVD. The connection of Eastern Channel at
Lockwood Folly Inlet is currently closed due to the migration of large sand shoal/spit. The proposed project will create a new
channel ranging from 40 to 100 feel wide connecting Eastern Channel to Lockwood Folly Inlet allowing safe navigation of
commercial and recreational vessels. Please note that a shallow channel (-2.5 ft to -5 ft NAVD) has recently formed in the
area planned for dredging.
The proposed action consists of dredging a channel with placement of beach compatible material on the beach at the West
end of the Town and placement of non -beach compatible material in the upland disposal area at Sheeps Island. A total of
229,000 cy of material will be excavated with approximately 201,800 cy of beach compatible material and 27,200 cy that will
be placed upland at Sheep Island. Excavations would be made by cutter head dredge and pumped via pipe to the beach or
upland disposal area.
Sediment would be spread via land -based equipment and shaped into a recreational beach between the existing toe of the
foredune and the low watermark. The beach fill will impact a total of 31.5 acres of beach and inshore area.
There will be two fill reaches of the project as illustrated in the permit drawings. Anticipating approximately 10% reduction of
volume of material (between what is dredged and ultimately placed on the beach), a total of 181,600 cy of material is
planned to be placed on the beach. The beach will include a flat berm at elevation +7.0 ft NAVD88 (based on a review of
numerous years of profile data for the existing berm elevation), extending seaward to a depth of (-)-7-8 ft NAVD88 on a 1:20
slope. A 20-ft wide dune with a crest elevation of +10.0 ft NAVD will be restored fronting the properties on west beach that
installed sandbags this year (6623, 6621, 6617, and 6615, West Beach Drive, Oak Island, NC).
Reach 1 extends from approximately the 6900 block of West Beach Drive to approximately 6000 block (2,900 feet). Along
this reach of shoreline, the project will contain -13 - 88 cubic yards (avg = 50) per linear foot (cy/ft) of beach fill, with a berm
width initially placed 20-95 feet (ft) wide (see attached drawings). A taper section -250 ft long will tie the main fill into the
natural shoreline at the ends of each reach. Lengths and volumes include the planned taper sections.
Reach 2 extends from approximately the 5700 block of West Beach Drive to approximately 5100 block (1,500 feet). Along
this reach of shoreline, the project will contain -25 - 35 cy/ft (drawing sections shown at worst case areas but avg = 25) of
beach fill, with a berm width initially placed 20-40 ft wide (see attached drawings). A taper section -250 ft long will tie the
main fill into the natural shoreline at the ends of each reach.
Sediment characteristics for the borrow area from recent borings are summarized in the narrative. Material placed on the
beach will be consistent with NCDCM sediment compatibility standards and will be visually monitored for sediment quality.
The Project would restore storm protection volumes and elevations and reduce potential storm damage to the sub -aerial
beach, protective berm, adjacent infrastructure, and coastal structures within the Project footprint. Once completed, public,
private, and commercial uses would continue including sunbathing, walking, wading, shelling, fossiling, fishing, etc.
c. Describe the proposed construction methodology, types of construction equipment to be used during construction, the number of each type
of equipment and where it is to be stored.
The proposed dredging of the navigation channel will be performed by a hydraulic cutter head dredge and conveyed to the
beach nourishment and upland disposal area via pipeline. The beach compatible material will be placed along the shoreline
as illustrated in the permit drawings. Only the profile above high water is controllable in beach nourishment construction;
intertidal and underwater portions of the profile will be subject to natural adjustment by waves.
Work will progress in sections within the proposed navigation channel from west to east and along the beach. The pumping
rate and construction duration will depend on the size of the dredge and pipeline used by the Contractor and duration may be
expected to be between 30 to 60 days.
Construction activities will involve movement of heavy equipment and pipe along the beaches. Once a section is complete,
piping and heavy equipment will be shifted to a new section and the process repeated. As soon as practicable, sections will
be graded and dressed to final slopes. Other than at temporary equipment staging areas, residents and visitors along the
project area will not experience significant disruption to recreational activities except within the immediate construction area.
Land -based equipment will be brought to the site over public roads and will enter the beach at existing beach access at the
western end of the island. Existing dunes and vegetation on the beach will be avoided and preserved; however, any
alteration of dune vegetation/topography necessary for equipment access will be repaired to pre -project conditions. Daily
equipment staging will be on the constructed beach seaward of the dune line. Construction contracts will provide for proper
storage and disposal of oils, chemicals, and hydraulic fluids (etc.) necessary for operation in accordance with state and
federal regulations.

Form DCM MP-1 (Page 6 of 7)
APPLICATION for
Major Development Permit
The proposed project involves dredging and placement of 201,800 cy of beach -quality sand. Based on the project
experiences and communication with potential contractors the proposed dredge may range in size from 16 to 24 inch
hydraulic dredges. Production rates will depend on the size of plant used and may range from 3,200 cy/day (16 in) to 7,000
cy/day ( up to 10,000 cy/day) if the 24 in dredge were used. The average production per day varies widely according to
transportation distance and specifications of the project. It is anticipated the proposed construction will be accomplished in
approximately one to two months. The project is planned to bid out in mid December with construction start in mid February.
Given the current schedule, a request will be made to extend the routinely approved environmental window (November 16
through March 31) by an additional month (to April 29th 2015) to ensure adequate time and provide an additional buffer due
to any unforeseen events.
d. List all development activities you propose.
Dredging a channel with placement of beach compatible material on the beach. Non -compatible material will be placed in the
upland disposal area at Sheeps Island. A letter of consent was provided by the NC State Property Office 4 December 2014
and has been included in this application package.
e. Am the proposed activities maintenance of an existing project, new work, or both? new work
f. What is the approximate total disturbed land area resulting from the proposed project? — 53.3 ❑Sq.Ft or ®Acres
g. Will the proposed project encroach on any public easement, public accessway or other area ®Yes []No ❑NA

h. Describe location and type of existing and proposed discharges to waters of the state.
A sand slurry mix would be pumped along the Project template in which diffusion plates will be used moderating discharge
velocity and direction therefore maximizing sand precipitation. Diverision rows of pushed sand will direct the slurry down the
beach supplementing additional sand deposition and minimizing potential swash zone turbidity effects.
i. Will wastewater or stormwater be discharged into a wetland? ❑Yes ®No ❑NA
If yes, will this discharged water be of the same salinity as the receiving water? ❑Yes ❑No ❑NA
j. Is there any mitigation proposed? []Yes ®No ❑NA

1.0 INTRODUCTION
1.1 Background
The Brunswick County Board of Commissioners and the United States Army Corps of
Engineers (USACE), Wilmington District have been considering and planning the Lower
Lockwoods Folly River Habitat Restoration Project for over 30 years (Figure 1). The overall
goals of the restoration project are to:
(1) Maintain the economic viability of tourism, the largest industry of Brunswick County (the
County) and the Town of Oak Island (the Town), and
(2) Preserve the environmental, cultural, and aquatic resources of the County and the Town by
providing improved navigation and water quality within the Eastern Channel while beneficially
using the dredged material (specifically to protect vulnerable infrastructure) to the maximum
extent practicable.
i
In 2009, the Brunswick County Board of Commissioners in collaboration with the Southeast
Brunswick Conservancy conducted a feasibility study focused on the need for navigation
improvements and the secondary environmental benefit of improved flushing within the
Lockwoods Folly River habitat. The portion of Eastern Channel which leads from Lockwoods
Folly Inlet to Montgomery Slough and the Davis Canal have both shoaled over time, altering the
estuarine hydrodynamics and the aquatic habitat of tidal creeks at the southern extent of the
Lockwoods Folly River. As evidenced in historical photographs dating back to 1938, there has
been periodic formation of marginal channels bisecting the flood shoal at Lockwoods Folly Inlet
and continuous sedimentation and migration of those channels (see Appendix A — Pre -
Application Agency Meeting Minutes).
The Lower Lockwoods Folly River Habitat Restoration Project, as envisioned by the County,
consists of two phases to improve the flushing and circulation in the lower Lockwoods Folly
River and to improve navigation in the Eastern Channel. Phase 1 includes improvement of
navigation of Eastern Channel via dredging and the beneficial use of beach -compatible dredged
material to nourish the western oceanfront shoreline of Oak Island to the maximum extent
feasible (Figure 2). Nonbeach-compatible material will be placed within an existing confined
disposal area on Sheep Island (Figure 2). Phase 2 includes improved flushing of the Galloway
Flats area. The project will be similar to the Section 206 project proposed by the USACE and
described in the Section 206 Preliminary Restoration Plan (July 2003). This USACE plan
sought funding in that year; however, Congress did not provide funding for environmental
projects.
1.2 Authorization
Beach nourishment permitting requires state and federal actions mandating review through the
Rivers and Harbors Act Section 10 and the Clean Water Act Section 404. These state North
Carolina Division of Coastal Management (NCDCM) and federal permitting actions

including the USACE's Section 404 authorization. Existing information for the proposed project
area is contained within several ongoing studies and previously issued USACE General
Revaluation Report and Draft Environmental Impact Statement for the Brunswick County
Beaches, Coastal Storm Damage Reduction Project. General Permit #s 63904-63907 were
issued for approximately 250 linear feet of sandbags protecting four (4) homes on 21 May 2014.
These same property owners applied for a major permit to install more sandbags in excess of
the 6-ft height and 20-ft base width allowable under current rules (personal communication,
Heather Coats, NCDCM, 17 November 2014).
As the Project Area is adjacent to Lockwoods Folly Inlet, project authorization at Lockwoods
Folly Inlet consists of a 12 feet (ft) deep (MLW — 15,ft deep NAVD) by 150 ft wide channel from
the deep water of the Atlantic Ocean to the intersection of the Atlantic Intracoastal Waterway
(AIWW) and a channel 6 ft deep by 100 ft wide from the intersection of the AIWW, extending
north within the banks of the Lockwoods Folly River and terminating at the NC State Highway
211 bridge. The USACE Wilmington District currently conducts maintenance dredging of the
inlet to 8 ft MLW within the outer part of the channel.
For this project, the USACE and NCDCM are acting as cooperating agencies in the analyses
required by the National Environmental Policy Act (NEPA). These federal permitting actions
trigger the development of Biological and Essential Fish Habitat Assessments. These
supplemental documents will be used by the USACE for consultation purposes with the United
States Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS).
1.3 Purpose and Need
The purpose and need for the restoration project is driven by (1) commercial and recreational
navigation requirements, (2) estuarine and riverine water quality degradation, and (3) coastal
oceanfront erosion, which is currently rendering infrastructure vulnerable and causing habitat
loss for sea turtle nesting.
Currently, navigation of Eastern Channel (a natural channel) is limited to high tides, and many
areas within the channel have severely shoaled to -4' to -6' North American Vertical Datum
(NAVD) which is equivalent to -V to -3' MLW. The connection of Eastern Channel at
Lockwoods Folly Inlet is currently closed due to the migration of a large sand shoal/spit. Phase
1 will create a new 100-ft wide channel connecting Eastern Channel to Lockwoods Folly Inlet,
which will allow the safe navigation of commercial and recreational vessels (Figure 2). A
shallow channel has recently formed in the proposed dredge area and is visible in the February
2014 aerial photograph (Figure 3). This channel location has been observed in many historical
aerial photographs as well (Appendix A). The flood shoal experiences heavy recreational use
by boaters for congregating and swimming.
Water quality has long been a concern of the Town. Nutrient and fecal levels have spiked in
Davis Creek, a tributary of Eastern Channel. Eastern Channel itself is designated as impaired
waters and has a surface water classification SA/HQW (Town of Oak Island, 2009 CAMA Land
Use Plan Update). The Town has recently invested over $177 million in a sewer system to limit
further water quality degradation into receiving waters. As documented by the North Carolina
Division of Water Quality (NCDWQ), fecal coliform data between 2008 and 2010 at the Davis
Canal Monitoring Station was above state standards for shellfish and swimming uses.

Improvements to navigation in Eastern Channel will result in additional tidal flushing, which will
improve water quality conditions.
Loss of property is another concern of the Town of Oak Island. A number of homes along the
west end of Oak Island are now vulnerable to damage. The 2013-2014 winter storms and
subsequent erosion have necessitated the installation of sandbags to prevent loss of these
homes (Photograph 1). A series of escarpments (6- to 8-ft-high) have formed along this reach
of shoreline and limit sea turtle nesting (Photograph 2).
The NCDCM permitted approximately 250 linear feet of sandbags protecting four (4) homes on
21 May 2014 (personal communication, Heather Coats, NCDCM, 17 November 2014). The four
(4) property owners applied for a major permit to install additional sandbags in excess of the 6-ft
height and 20-ft base width allowable under current rules. The Coastal Resources Commission
(CRC) granted a variance request on 19 November 2014. Homeowners will construct sandbag
protection with a maximum base width of 30-feet. Homeowners will be allowed to maintain the
bags at the height of the erosion escarpment since additional sand loss on the beach after the
installation caused the sandbags to drop approximately 6 — 8 feet below the escarpment behind
the bags (personal communication, Heather Coats, NCDCM, 24 November 2014).

In summary, Phase 1 will accomplish the following:
Dredging Eastern Channel will yield approximately 201,800 cubic yards (cy) of beach -
compatible material that will be placed on the western beaches of Oak Island (Figures 2 and 3)
to protect existing infrastructure and provide suitable turtle nesting habitat.
• Restore estuarine habitat surrounding the Eastern Channel of the Lockwoods Folly River
and improve water quality conditions within the Montgomery Slough (currently listed as
an impaired water body) (CAMA Land Use Plan 2009);
• Provide a safe channel for both commercial and recreational navigation for shallow draft
vessels; and
• Provide protection of infrastructure on the western oceanfront shoreline of Oak Island
while maintaining tax revenues to the Town, County, and state.

2.0 DESCRIPTION OF THE PROPOSED ACTION
2.1 Project Design
As a basis of design for the proposed navigation channel, Moffatt & Nichol: (a) reviewed
historical data and prior investigations to qualitatively assess historical sedimentation patterns
and channel stability, (b) sized the channel cross-section using empirical methods, and (c)
quantified the expected shoaling rates and patterns using empirical methods and review of
model investigations by others.
2.1.1 Historical Sedimentation Patterns
As documented by prior investigation [Coastal Science and Engineering (CSE) 20091 and
illustrated in the aerial photographs from 1938 to 2014, there has been episodic formation and
subsequent shoaling of bisecting channels through the flood shoal at Lockwoods Folly Inlet and
the ebb shoal of Eastern Channel (Appendix A). Historically, there has been significant
migration and periodic closing of the Eastern Channel. The presence, size, and orientation of
the channels have varied significantly from a channel parallel and adjacent to the backside of
Oak Island, through the flood shoal in the proposed location to parallel to Sheep Island. In
1978, a pilot channel was dredged parallel to Sheep Island; within five years the channel had
migrated south and by 1986 it followed an alignment similar to that which is currently proposed.
The Eastern Channel shifted to an east — west orientation parallel to the backside of Oak Island
by 1996. From 1996 to 2013, the Eastern Channel followed that orientation with periodic
shoaling and channel closure.
Within the past year, as illustrated in the 2014 aerial photograph (Figure 3), a spit has formed
from Oak Island parallel to the Shallotte Inlet channel, effectively closing the Eastern Channel
(orientation due west). The proposed channel dredging alignment follows the recently formed
shallow channel as described above.
The proposed action consists of dredging a new channel within Eastern Channel and placing
compatible dredged material on the beach at the west end of Oak Island while placing non -
compatible material in the upland disposal area on Sheep Island. A total of approximately
229,000 cy of material will be excavated including approximately 201,800 cy of beach -
compatible material for Oak Island and 27,200 cy non -compatible material for Sheep Island.
Excavations would be made by cutterhead pipeline dredge and material would be pumped via
pipeline to the beach or upland disposal area (see details of the pipeline in Appendix B —
Pipeline Drawing). The pipeline is located 22-feet west of the centerline of 57t' West Beach Dr.
Public Works Director, John Michaux, will provide guidance to exact location to agencies
(personal communication, John Michaux, Town of Oak Island, 17 November 2014). A letter of
consent for the disposal of non -compatible material into Sheep Island (Disposal Area #286 was
received from the NC State Property Office 4 December 2014. A copy of the letter is provided
in the CAMA Major Permit Application package.
Sediment would be distributed via land -based equipment and shaped into a recreational beach
between the existing toe of the foredune and the low watermark. The beach fill will impact a
total of 22.4 acres of intertidal and dry beach area.

Phase 1 — Eastern Channel November 2014
[3

There will be two fill reaches on Oak Island as identified in Table 1 and illustrated in Figures 4,
5, and 6. Additional detailed permit drawings are provided in Appendix C. Anticipating an
approximate 10% reduction of volume of material (between what is dredged and ultimately
placed on the beach), a total of 181,600 cy of material is planned to be placed on the beach.
The beach will include a flat berm at elevation +7.0 ft NAVD88 (based on a review of numerous
years of profile data for the existing berm elevation), extending seaward to a depth of
approximately -7-8 ft NAVD88 on a 1:20 slope. A 20-ft-wide dune with a crest elevation of
+10.0 ft NAVD will be restored fronting the west beach properties that installed sandbags this
year (6623, 6621, 6617, and 6615 West Beach Drive, Oak Island, NC) (General Permits 63904-
63907).
Reach 1 extends from approximately the 6900 block of West Beach Drive to approximately the
6000 block (2,900 ft) (Figures 4 and 5). Along this reach of shoreline, the project will contain
—13 to 88 cy [average (avg) = 50] per linear ft of beach fill with a berm width initially placed at 20
to 95 ft. A —250-ft long taper section will tie the main fill into the natural shoreline at the ends of
each reach. Lengths and volumes include the planned taper sections.
Reach 2 extends from approximately the 5700 block of West Beach Drive to approximately the
5100 block (1,500 ft) (Figure 6). Along this reach of shoreline, the project will contain —25 to 35
cy/ft (avg = 25) of beach fill with a berm width initially placed 20 to 40 ft. A —250-ft long taper
section will tie the main fill into the natural shoreline at the ends of each reach.
Sediment characteristics for the borrow area from recent borings are summarized below in
Section 2.4. Material placed on the beach will be consistent with the NCDCM sediment
compatibility standards (15A NCAC 07H .0312) and will be continuously visually monitored for
sediment quality during construction and immediately after.

2.1.2 Basis of Design of the Proposed Channel
CSE (2009) conducted Feld measurements of tidal water levels, discharges, and current speeds
at selected locations in the Lockwood's Folly inlet system, including the main inlet channel, the
Eastern Channel, and in the AIWW. From these measurements, they reported the Eastern
Channel maximum flood current velocity to be 2.3 ft/second (sec) and the maximum ebb current
velocity to be 3.3 ft/sec. CSE (2009) reported the Lockwood's Follow inlet flood tidal prism at
475 million cubic feet, with approximately 77.6 million cubic feet tidal prism assigned to the
Eastern Channel.
If the Eastern Channel is considered as a tidal inlet, the equilibrium cross -sectional channel
area (Ac) can be calculated for the reported tidal prism (P) using empirical relationships. The
empirical relationship determined by Jarrett (1976) for Atlantic Coast inlets is:
& _ (7.75 x 10-1) pl.05
For the Eastern Channel's reported tidal prism of 77.6 million cubic feet, the corresponding Ac =
1,492 square feet. Using O'Brien's (1966) empirical calculations for the all inlets (including
those with jetties), the corresponding Ac = 2,000 square feet.
Currently near the west end of the Eastern Channel adjacent to Lockwood Folly Inlet, the
channel has shoaled in, with an existing cross -sectional area of 250 — 400 square feet. The
proposed channel cross -sectional area is 2,150 square feet. Along the reach of the main
channel south of Sheep Island, the average cross -sectional area is currently 850 square feet
with a proposed cross -sectional area of approximately 1,750 square feet.
The proposed channel is designed at the entrance (from Station 0+00 to station 18+00) to be
cut to -15 ft NAVD with a base width of 100 ft and side slopes of 3:1 (H:V). The proposed
channel cross-section will narrow to 75 ft at station 25+00 and maintain this width to station
40+00; the channel base width is proposed to be 40ft at station 41+00 eastward. The proposed
base elevation and depth varies as illustrated in the permit drawings with a more shallow
channel (-9 ft NAVD) proposed east of station 50+75 where dredged material will be transported
to the upland disposal site.
2.1.3 Predicted Performance
In support of the proposed Holden Beach East End Shore Protection Project, Applied
Management and Technology (ATM) (2013) developed and applied a hydrodynamic and
sediment model to evaluate alternative scenarios for managing the Lockwood Folly Inlet system.
An alternative simulating the dredging of Eastern Channel was presented with a northwest
orientation parallel to Sheep Island. Based on the modeling, it was concluded that the relocated
Eastern Channel would maintain its depth, the increased tidal prism may allow for improved
water quality and it will not have a significant effect on the adjacent shorelines. The model also
illustrated what practically would be expected that if the proposed Eastern Channel was
dredged parallel and adjacent to the backside of Oak Island (east - west) it would shoal much
more quickly than if it were oriented to the northwest.

Phase 1 — Eastern Channel November 2014

Moffatt & Nichol employed an empirical method developed by Eysink (1983) to estimate the
sedimentation rate for the proposed channel. Following the Eysink method, sedimentation rate
is a function of the rate of tidal exchange, settling time, sediment concentration and fall velocity.
Tidal exchange is estimated as a function of the tidal prism, horizontal eddies from discharge
and density driven currents. Employing this method, the mouth of the channel (station 0+00 to
25+00) is expected to shoal in within 1 to 4 years; further to the east of station 25+00, the
proposed channel is estimated to shoal within 3 to 6 years.
The proposed channel is not anticipated to have significant effects on the shoaling patterns
within Lockwood Folly Inlet.
2.2 Methods of Construction
The proposed dredging of Eastern Channel will be performed by a cutterhead pipeline dredge
and conveyed to the beach placement areas via pipeline (Figures 7 and 8). It is expected that
the contractor will use floating pipeline that will daylight onto the beach for the western sections
of placement. For the eastern areas, the Town has an existing easement and a 24- inch (in)
reinforced concrete pipeline existing within the Town's easement (Appendix B) which crosses
underneath the beach road near the marina. It is expected that this corridor will be used for the
pipeline placement for the eastern sections of the project. The beach -compatible material will
be placed along the shoreline as illustrated in the permit drawings (see Appendix C). Only the
profile above high water is controllable in beach nourishment construction; intertidal and
underwater portions of the profile will be subject to natural adjustment by waves (Figure 9).
Construction will progress in sections within the proposed dredging area and along the beach
from west to east (Figure 2). The pumping rate and construction duration will depend on the
size of the dredge and pipeline used by the dredging, but is expected to be between 30 and 60
days.
Incompatible material will be placed in Sheep Island last (Figures 10 and 11). Sheep Island has
a capacity of approximately 40,000 cy. The proposed dredge material (27,200 cy) will be
graded such that a minimum of 1 ft will be maintained between the crest of the existing dike and
the proposed fill adjacent to the dike. It should be noted that the crest elevation around the
perimeter of the disposal area varies; around the perimeter the crest is typically 22 ft NAVD to
24 ft NAVD, with the exception of the vicinity of the outlet structure. Near the outlet structure,
the crest elevation is approximately 20 ft NAVD along length of approximately 50 linear feet of
the dike rising up to 21 ft NAVD over a length of approximately 275 linear feet. The crest
elevation of the dike could be raised to a minimum of 22 ft NAVD in order to increase the
capacity of the disposal area to 40,000 cy (at El 21 ft NAVD88).
A letter of consent from the NC State Property Office was provided 4 December 2014 and is
included in the CAMA Major Permit application package. Photographs 3 and 4 below depict the
water control structure and pipe location within the spoil site.
Construction activities will involve movement of heavy equipment and pipe along the beaches.
Once a section is complete, piping and heavy equipment will be shifted to a new section and the
process repeated. As soon as practicable, sections will be graded and dressed to final slopes
(Figure 9). Other than at temporary equipment staging areas and within the immediate.

construction area, residents and visitors in the Project Area will not experience
significant disruption to recreational activities.
Land -based equipment will be brought to the site over public roads and will enter the
beach at existing beach access points along the western end of Oak Island. Existing
dunes and vegetation on the beach will be avoided and preserved; however, any
alteration of dune vegetation/topography necessary for equipment access will be
repaired to pre -project conditions. Daily equipment staging will be located on the
constructed beach seaward of the dune line. Construction contracts will provide for
proper storage and disposal of oils, chemicals, and hydraulic fluids necessary for
operation in accordance with state and federal regulations.
The proposed activities may produce temporary and localized turbidity increases which
are normally associated with hydraulic cutterhead dredging and standard beach
nourishment operations. The effect of turbidity levels in the borrow area is expected to
fall within the natural range of background conditions (25 NTU).
2.3 Construction Schedule
The proposed project involves dredging and placement of 201,800 cy of beach -quality
sand. Based on the experience of and communication with potential contractors, the
proposed dredge may range in size from 16- to 24-in hydraulic dredges. Production
rates will depend on the size of plant used and may range from 3,200 cy/day (16 in) to
7,000 cy/day (up to 10,000 cy/day) if the 24-in dredge is used. The average production
per day varies widely according to transportation distance and specifications of the
project. It is anticipated that the proposed construction will be completed within two
months. Project sponsors will request project bids in mid -December 2014 with
construction to start in mid -February 2015. Given the current schedule, a request will be
made to extend the routinely approved environmental dredging/construction window
(November 16 through March 31) by an additional month (to 30 April) to ensure
adequate time and provide an additional buffer due to any unforeseen events.
As per the USACE — Wilmington District Maintenance Dredging Specifications for the
AIWW, Bogue Inlet Crossing to Shallotte Inlet Crossing (2013) an environmental window
of 16 November to 30 April applies to the disposal of dredged material, the movement of
equipment, including pipe relocation, pipe stockpiling, and pipe removal, and all
escarpment leveling, final grading, etc on all oceanfront beaches. This window protects
nesting and hatchling sea turtles.

2.4 Sediment Compatibility
2.4.1 Native Beach Sediment
The native sediment distribution for Oak Island was defined based on the percent gravel,
granular sediment, sand, fine-grained sediment, and calcium carbonate present in
samples taken from 13 locations along a specific transect (Figure 12). These 13
samples were then averaged to obtain a composite average for that transect. Five
transects were sampled along the western shoreline of Oak Island where sand
placement is proposed (Figure 12). The composite average for each of the five
transects were then averaged to obtain an overall average for the native beach. A
summary of the distribution and statistics for the native sediment is provided in Tables 2
and 3.
The native material is characterized as well -sorted fine sand under the American Society
for Testing and Materials (ASTM) Unified Soil Classification System with a mean grain
size of 0.28 millimeter (mm).
In addition, an assessment of the total number of sediments and shell material greater
than 3 inches between the frontal dune and Mean Low Water (MLW) was completed on
18 November 2014 based on requirements of 15A NCAC 07H.0312 One area (300' x
90'=27,000 square feet) was reviewed in Reach 1 (Figures 4 and 5) with the number of
sediments greater than 3 inches being 27. Within Reach 2, a single area was delineated
(300' x 90'=27,000 square feet) and the number of sediments/shells greater than 3
inches was 10 (Figure 6): The equivalent number of sediments/shells greater than 3
inches 50,000 square feet for Reach 1 and Reach 2 would be 50 and 18 respectively.
2.4.2 Proposed Dredged Sediment
Athena Technologies Inc. collected a total of 22 vibracores for the geotechnical pre -
dredge sediment assessment (Figure 13) (Appendix D). A total of 16 vibracores were
sampled within the proposed dredging area in Eastern Channel. Findings from analyses
of these samples were used to determine the quantity of beach -compatible and
incompatible material for the proposed dredge design depths [based on tidal prism
stability analyses (CSE 2009)]. Based on the available data, the material west of Station
50+75 (Figure 4) was determined to be beach -compatible sand (vibracores 18, 17, 12,
11, 10, 9, 8, 22, and 7). The material east of Station 50+75 (vibracores 21, 6, 5, 4, 3, 2,
and 1) was predominantly composed of silt and clay, which are not beach compatible.
Sediment characteristics for the vibracores west of Station 50+75 and east of Station
50+75 are provided in Table 4 and Table 5, respectively. Sediment statistics for the
vibracores west of Station 50+75 and east of Station 50+75 are provided in Table 6 and
Table 7, respectively. While a couple of the vibracores have gravel that are individually
out of compliance (within 1 % rounding — shown in red in the tables), the overall average
is well within compliance (see Tables 8 and 9).

Note that the bottom foot of vibracore EC-14-09 (from elevation -14 ft NAVD 88 to -15 ft
NAVD 88) was `lost" as noted by the contractor performing the work (Athena
Technologies); the material was predominantly shell hash. The material recovered at
the borings adjacent to EC-14-09 was used as basis for characterization of the range of
sediment characteristics that may be reasonably anticipated. Samples from the
comparable elevation (-14 ft NAVD 88 to -15 ft NAVD 88) is characterized as fine and
medium sands at vibracores EC-14-08 and EC-14-10, respectively.
Table 8ables 8 and 9 provide a comparison of the composite of the proposed fill to that
of the native sediment. The proposed fill composite has a median grain size of 0.31 mm,
which is slightly larger than the native grain size of 0.27 mm. The proposed material is
poorly sorted fine sand with a slightly higher percentage of gravel and shell hash than
that of the native composite but well within state standards.
2.5 Alternative Designs and Analysis
Prior to choosing the preferred dredge location as described in the previous sections,
three options for the mouth of the Eastern Channel were considered and discussed in
detail with stakeholders 28 August 2014 during the pre -application agency meeting
(Figure 14) (Appendix A). An updated summary of findings memo describing the
preferred alternative was distributed'by Moffatt & Nichol via email 24 October 2014 to
stakeholders (Appendix F).
Dredging Option 1 (adjacent to Sheep Island) includes a channel alignment towards the
north (AIWW) and involves dredging approximately 204,100 cy of compatible sand for
beach placement and approximately 34,000 cy of noncompatible material to be placed in
the confined disposal area on Sheep Island.
Dredging Option 2 (preferred option - through the inlet flood shoal) includes a channel
alignment towards the northwest and involves dredging approximately 201,800 cy of
compatible sand for beach placement and approximately 27,200 cy of noncompatible
material to be placed in the confined disposal area on Sheep Island.
Dredging Option 3 (parallel and adjacent to the north shore of Oak Island) includes a
channel alignment due west and involves dredging approximately 164,000 cy of
compatible sand for beach placement and approximately 34,000 cy of noncompatible
material to be placed in the confined disposal area on Sheep Island.
All channel options are proposed to be dredged approximately 50 to 100 ft-wide with an
average depth of dredging ranging from 3 to 11 ft on a 3:1 slope. Option 1 was
determined to be the least desirable since it was well out of compliance for percent fines
and just barely out of compliance for percent gravel (within 1 percent). The material
(median d = 0.25 mm) was slightly finer than that of the native material (median d = 0.27
mm). Option 2 was determined to be the next best alternative with only two individual
vibracores just barely out of compliance with gravel (within 1 percent) and the average of

Phase 1 — Eastern Channel

Figure 14. Eastern Channel Alignment Options
all vibracores within compliance. The material (composite median d = 0.35 mm) was generally
coarser than the native sand (median d = 0.27 mm). Option 3 was the best option from a beach
compatibility perspective with all individual vibracores being in compliance. The material
(composite median d = 0.33 mm) was slightly coarser than the native sand (median d = 0.27
mm). However, this option was also the most likely to shoal given its vicinity to the inlet and
past geomorphological behavior.
Based on both the sediment compatibility analyses and consideration of long-term channel
stability, it was recommended that the Town proceed with design and permitting following the
proposed alignment described for Option 2. This option should provide improved channel
stability as compared to Option 3 while providing more consistent beach -compatible material
than Option 1. Therefore, Option 2 is the only option considered in this Major Permit
Application.

4.0 PROPOSED CONSERVATION MEASURES
The timing of construction activities was specifically scheduled to occur outside of the sea turtle
nesting season, the West Indian manatee summer occurrence in North Carolina, the piping
plover (and other shorebirds) migratory and breeding seasons, and for the most part the
seabeach amaranth flowering period. Also, sand placement and dredge operation conducted
outside of primary invertebrate production and recruitment periods (spring and fall) limit effects
to amphipods, polychaetes, crabs and clams.
Proposed conservation measures resulting in avoidance and minimization of potential effects
from dredge fleet activities are bulleted below.
• Seasonal environmental dredging/nourishment window (mid -February through 30 April)
would be a contract stipulation ensuring potential terrestrial, estuarine, and marine
biological process effects are minimized.
• Survey/dive efforts assessing SAV within the Project area have been evaluated and the
dredging footprint and transport route are absent of SAV resources.
• Dredging and placement areas would be documented by Global Positioning Systems
(GPS) units ensuring sand resources are within authorized areas.
• Associated dredging vessel speed restrictions <11.5 miles per hour would be employed
reducing potential collision effects with managed or associated species (Northern Right
Whale) as well as recreational vessels.
• Directional, shielding, and intensity managed lighting would be employed minimizing
potential nocturnal marine species' effects, while meeting Occupational Safety and
Health Administration (OSHA) vessel work standards.
• Contract language will require routine inspection of dredging equipment and transport
piping to minimize potential leaks at the dredge plant and along transport corridors.
• Contract language will require water pollution control and spill response and waste
management plans for all dredging fleet equipment.
NCDCM Major Permit Application
Phase 1 — Eastern Channel
34
Dial Cordy and Associates Inc.
November 2014

• Contract language will require proposed work be performed in accordance with U.S.
Coast Guard regulations.
Proposed conservation measures resulting in avoidance and minimization of potential effects
from recipient beach activities are bulleted below:
• All beach equipment (bulldozers, frontend loaders, pickups, etc) would access current
public access areas, no new access cuts would be allowed.
• Existing vegetated dune fields would not be disturbed and equipment/personnel would
not be allowed within these dune line buffers.
• Contract language would require equipment refueling locations within designated
equipment staging areas away from the active work zone if practicable.
• Contract language would require designated contract spill response capabilities.
• If available, staging areas for construction equipment would be located off the beach.
• Construction equipment, not in nighttime use, would be stored off the beach, if
practicable, minimizing potential effects on nocturnally active species.
• Diffusion plates would be a contract stipulation reducing effluent discharge velocities
with directional sand -slurry placement.
• Temporary slurry diversion training walls would be pushed up from existing and received
material extending and directing the sandy effluent's horizontal flow maximizing
sediment retention and minimizing potential swash zone turbidity effects.
• Visual monitoring would be required during all sand slurry discharging operations with
"shut down" and agency notification authorization in the event unsuitable material is
encountered.
• Directional, shielding, and intensity managed lighting will be employed minimizing
potential nocturnal species' effects, while meeting OSHA work standards.
• Contract language would require routine inspection of slurry transport piping minimizing
potential pressurized leaks along the beachfront.

• Heavy equipment would be removed from refurbished shorelines as soon as practicable
restoring unrestricted public access.
Summary of Potential Effects
The proposed Project would adhere to above conservation measures, sand quality and
proposed construction scheduling. Sand compatibility, seasonal dredging/renourishment
windows, good engineering/best management practices, and conservation measures would
offset potential direct, indirect, and cumulative effects on protected species potentially found
within the proposed Project Area (Appendix E — Draft Biological Assessment).
Of the 21 federally listed or proposed species with known or potential occurrence in this portion
of Brunswick County, 12 were considered in the Biological Assessment based on evaluations of
potential occurrence in the Project Area. Potential direct and indirect impacts from the proposed
dredging and sand placement activities were assessed for each species as were measures to
minimize these impacts. The proposed construction activities were determined to have no
effect on the shortnose and Atlantic sturgeon, West Indian manatee and the wood stork since
these species are expected to have a low or no occurrence in the Project Area during the
construction activities (mid -February through April 30). Proposed construction activities may
affect, but are not likely to adversely affect, the following species: piping plover, red knot,
seabeach amaranth, leatherback turtle, loggerhead turtle, green turtle, Kemp's ridley turtle and
hawksbill turtle. Impacts of the proposed activities on critical habitat designated within the
Project Area were also assessed. Proposed sand placement activities may affect, but are not
likely to adversely affect, piping plover critical habitat (NC -16 unit) or loggerhead critical habitat
(LOGG—T—NC-07 and LOGG—N-5). Proposed dredging activities were determined to have no
effect on these loggerhead critical habitat units.
To minimize direct and indirect impacts of the proposed actions on species and critical habitats,
the proposed project will adhere to the USFWS's two most important conservation measures:
monitoring sand compatibility and scheduling construction to avoid sensitive environmental
windows. Sand compatibility, seasonal dredging/nourishment windows, best management
practices and conservation measures will offset potential direct and indirect effects on protected
species and critical habitats in the Project Area.
Shell bottom, SAV, and tidal marsh habitats; along with state -designated nursery areas, were
avoided during project design and do not occur within the proposed channel dredging footprint
(Appendix G — Draft Essential Fish Habitat Assessment). Dredging is anticipated to directly
impact —6.3 acres of intertidal non -vegetated flats and —16.3 acres of shallow subtidal soft
bottom habitat in the Eastern Channel. Temporary losses of intertidal and subtidal soft bottom
habitats and associated benthic invertebrate communities are anticipated to have minor short-
term adverse effects on federally managed fisheries; including Peneaid shrimp and red drum.
Sediment suspension and associated increases in turbidity during the dredging process are
anticipated to have short-term, localized adverse effects on water quality and estuarine habitats
and communities. However, improved tidal circulation and flushing is anticipated to have long-
term net beneficial effects on water quality, habitats, and communities; including state -
designated Primary and Secondary Nursery Areas. Beach fill placement along the Oak Island

west end oceanfront beach is anticipated to directly impact —9 acres of intertidal beach habitat
and —16 acres of nearshore subtidal soft bottom habitat. Temporary losses of intertidal and
subtidal habitats and associated benthic invertebrate communities are anticipated to have minor
short-term adverse effects on federally managed fisheries.
5.0 COMPLIANCE WITH BRUNSWICK COUNTY AND CAMA LAND USE PLAN
The proposed Project is consistent with the approved CAMA Land Use Plans for Brunswick
County and the Town of Oak Island. The project property is within the planning jurisdiction of
Brunswick County and the Town of Oak Island and is classified "Developed" by the CAMA Land
Use Plan.
6.0 COMPLIANCE WITH THE N.C. ENVIRONMENTAL POLICY ACT
The NCDCM has determined that review of this project under SEPA is not required.
The NCDWQ in Wilmington will be provided a full copy of the NCDCM permit application
describing the scope of the project and requesting a 401 Water Quality Certification.
7.0 CONSTRUCTION EASEMENTS
The Town of Oak Island is acquiring the required easements (approximately 86 lots) to
construct the proposed project. The easements will allow all work necessary to nourish the
beach. However, the Town of Oak Island cannot damage permanent improvements in the
easement area but must work with property owners to remove and replace permanent
improvements in the easement area that obstruct nourishment.
