8. PROJECT SUMMARY: The Town of Ocean Isle Beach proposes to obtain state authorization for a
30 -year management plan to continue beach nourishment along the island's oceanfront shoreline expanding
on the beach fill template authorized under the federal Coastal Storm Damage Reduction (CSDR) project. The
Town of Ocean Isle Beach plans to use the existing Shallotte Inlet borrow area for the federal CSDR project to
re -nourish approximately 27,650 linear feet on the oceanfront area.

9. PROJECT DESCRIPTION:
August 15, 2016
The project site includes the current Shallotte River Inlet Borrow Area for the federal CSDR project, the eastern
oceanfront shoreline of Ocean Isle Beach including the template area for the federal CSDR project and State
Permit No. 91-05 and a westward extension for an additional 1.75 miles from the eastern most limit of the
CSDR tapering towards Tubbs Inlet. To find the project site from US Highway 17 South travel approximately
34 miles on US 17 South after the exit towards Shallotte/Myrtle Beach and turn left on Ocean Isle Beach Rd
SW. Travel approximately 3.6 miles on Ocean Isle Beach Rd SW to the base of the Ocean Isle Beach Bridge.
The Shallotte River Inlet CSDRP Borrow Area is located on the northern end of Ocean Isle Beach.
The project site encompasses approximately 5.0 miles of oceanfront shoreline along Ocean Isle Beach, a
barrier island located in Brunswick County near the Town of Shallotte. Holden Beach borders to the east, the
Atlantic Ocean to the south, the AIWW to the north, and Sunset Beach to the West. The Island of Ocean Isle
Beach is flanked on the east end by Shallotte Inlet and on the west end by Tubbs Inlet. The approximate
elevation of the tract is 0 ft. -15 ft. above Mean Sea Level. The area of Ocean Isle Beach between Shallotte
Boulevard and Duneside Drive (baseline station 10+00 to 181+00) has utilized a static vegetation line since
1998. The Town of Ocean Isle Beach has obtained and renewed the Static Line Exception designation as per
15A NCAC 07J.1200.
The island is heavily developed with mostly residential development. The high ground portion of the property is
vegetated primarily with American Beach Grass (Ammophila breviligulata) and Sea Oats (Uniola paniculata).
The long term annual erosion rate for the Town of Ocean Isle Beach varies from 2.0 ft. -6.5 ft./year, per the
Division of Coastal Management's 2011 Annual Erosion. Rate maps. The 100 -year storm recession is
approximately 300' resulting in a total Ocean Hazard AEC that ranges from approximately 420 ft. to as much
as 690 ft. nearing the Shallotte Inlet.
The application states that the federal Coastal Storm Damage Reduction project (CSDR) was initially
constructed in 2001 with the placement of 1,866,00 cubic yards of material obtained from the Shallotte Inlet
Borrow area. The USACE Shallotte Inlet Borrow Area was also designated as a source for periodic beach
nourishment every 3 years. The federal project has received nourishment on two separate events, once in April
2010 and once in April 2014. According to the application, the CSDR template includes a dune crest elevation
of +8.5 ft. NAVD88 fronted by a 50 ft. wide berm with a crest height of +6.0 ft. NAVD88 for areas within
baseline station 51+50 to 103+00. The east and west transition areas have varying berm width keeping to an
elevation of 6' NAVD88. The CSDR project has been conducted approximately every four years utilizing sand
material from the Shallotte Inlet Borrow Area.
The Town of Ocean Isle Beach was issued CAMA Major/ Dredge and Fill State Permit #91-05 on June 28,
2005 for the nourishment of approximately 2,700 linear feet of oceanfront shoreline at the far east end of the
island utilizing sand dredged from the Shallotte Inlet CSDR borrow area. This permit was modified on April 28,
2006 to authorize the use of a high ground borrow site known as the "Lakes of Lockwood Borrow Site", which
is also authorized for use by the Town of Holden Beach under State Permit #14-02, and to authorize trucking
of this material to the beach.
Historically, the US Army Corps of Engineers (USACE) has maintained the AIWW Crossing Tangent 17-20 as
a marked navigation channel. Traditionally, they have maintained a depth of -12 ft. at MLW plus- 2 ft. overcut
in the AIWW Crossing. Shallotte River Inlet has not been federally maintained and is a federally authorized
CSDR borrow area only. The Town of Ocean Isle Beach currently maintains State Permit #51-16, one of the
Shallow Draft Inlet -5 (SDI -5), to perform navigation maintenance work in a defined channel of Shallotte inlet to
a maximum depth of -13ft. MLW plus a -2 ft. overcut as well as the AIWW Crossing with a maximum depth of
-12 ft. MLW plus a - 2ft. overcut. The project template for the SDI -5 beneficial placement on Ocean Isle Beach

Town of Ocean Isle, Beach- c/o CP& E
Page Three
August 15, 2016
mimics the federal CSDR Project template, the USACE nearshore disposal template and the beach template
authorized under State Permit #91-05 adjacent to the Atlantic Ocean. The Shallotte Inlet SDI -5 permit also
designates USACE Disposal Area 300 as a placement area for non -beach compatible material.
The application noted that the proposed construction of a terminal groin and the associated beach fill is not a
part of the proposed 30- year management plan.
The Town of Ocean Isle Beach Land Use Plan does not have the dry sand beach classified; however, the
upland areas of this project are classified as Developed. The waters of the project site are classified as SA by
the NC Division of Water Quality. The NC Division of Marine Fisheries has NOT designated this area of the
AIWW/Shallotte Inlet/Atlantic Ocean.as a Primary Nursery Area (PNA), and the waters are OPEN to the
harvesting of shellfish.
10. PROPOSED PROJECT:
The Town of Ocean Isle Beach proposes to obtain state authorization for a 30 -year management plan to
continue beach nourishment along the island's oceanfront shoreline, expanding on the beach fill template
authorized under the federal Coastal Storm Damage Reduction (CSDR) project. The Town of Ocean Isle
Beach plans to use the existing Shallotte Inlet borrow area for the federal CSDR project to re -nourish
approximately 27,650 linear feet on the oceanfront area. .
The proposed beach management plan would include beach nourishment within the existing template under
the CSDR, which encompasses approximately 3.25 miles of the towns approximate 5.5 -mile oceanfront
shoreline. As stated in the application, the existing CSDR template starts at baseline station 10+00 and
extends west to baseline station 181+00. The proposal would account for approximately 80,000 yd3 per year or
400,00 yd3 every 5 years for the eastern portion of the CSDR between baseline station 0+00 and station
120+00. The western portion of the CSDR beach nourishment template between baseline station 120+00 and
181+00 would require approximately 12,000 yd3 of material per year or 60,000 yd3 every 5 years, according to
the application.
The town is proposing to extend the template to include beach fill construction west of the current federal
CSDR project The proposal would include an additional 1.75 miles of beach construction to baseline station
265+00 with a taper to baseline station 275+00 adjacent to Tubbs Inlet. Beach compatible fill material would be
dredged from the Shallotte Inlet Borrow Area using a hydraulic pipeline dredge and would not exceed the
depths or dimensions authorized under the SDI -5 permit. The design profile proposes a beach fill area with an
average width of 172 ft. that would be constructed to include a 10ft. in width dune with a crest elevation of
+12.5 ft. NAVD88. This dune would be fronted by a 40 ft. in width berm with a crest elevation of +6.0 ft.
NAVD88. The landward slope of the proposed dune would measure approximately 1:5. The oceanward slope
of the dune would measure approximately 1:10.
The applicant is proposing to utilize the Shallotte Inlet Borrow Area as the primary sand source, following the
same dredge footprint as the USACE borrow area for the CSDR and the SDI -5 navigation project. The
applicant is not proposing to exceed the authorized channel depth of -13 ft. MLW plus a -2 ft. overcut.
According to the application, the proposed channel width would match the USACE Wilmington District Shallotte
Inlet CSDR Borrow Area of approximately 950 ft. wide at the AIWW and 1,400 ft. wide at the bar channel with a
side slope of 3:1 consistent with the width and slope dimensions for the SDI -5 Inlets. The application states
that the typical Shallotte Inlet CSDR project excavates approximately 65,000 yd3 during each event.
According to the applicant, bathymetric data collected by the USACE in July and August of 2013 indicated
approximately 1,312,000 yd3 of sand were available within the borrow area. The Town of Ocean Isle Beach
estimates that approximately 800,000 yd3 of material was dredged and used during the 2014 maintenance
event. The applicant states that the borrow area is expected to re -charge due to shoaling of the Shallotte Inlet
complex.

Town of Ocean Isle Beach- c/o CP& E August 15, 2016
Page Four
The application sites the Environmental Impact Statement (EIS) that was presented with the Ocean Isle Beach
terminal groin application as a source for the geotechnical evaluation of the sediment within the Shallotte Inlet
Borrow Area. The EIS indicated that vibracore data collected in 1998, 2005, and 2009 all showed the sediment
in the proposed borrow area met the criteria defined in rule 15A NCAC 07h.0312 (3)(a). USACE Disposal Area
300 has been designated as a disposal location in the event that any incompatible material is removed.
Construction would involve using a hydraulic pipeline dredge for the proposed removal of material from the
Shallotte Inlet borrow area. Disposal of beach quality sand onto the beach would be accomplished via pipeline,
using a direct pump -out for placement. Bulldozers and excavators would then shape and grade the discharged
material according to the proposed design template. The proposed project and future maintenance events are
proposed to occur within the environmental dredge window, between November 15 and April 30.
In summary, the proposed beach fill and nourishment associated with dredging activities would remain within
the Town limits. According to the applicant, all maintenance excavation is consistent with federal projects
thereby not exceeding the depth and width. The proposed Shallotte Inlet Borrow Area is the existing federal
CSDR project borrow area. As proposed, the project would mimic the current CSDR beach fill template and
extend construction west of the federal project towards Tubbs Inlet.
11. ANTICIPATED IMPACTS
The proposed excavation volumes are approximately 262,000 yd3 from the Shallotte Inlet CSDR borrow area
for the initial construction of the new west end beach fill template (181+00 - 250+00). An additional
approximately 185,000 yd3 would be used oceanward of the design template as an initial nourishment for
anticipated erosion during the construction process prior to the first periodic nourishment event. Periodic
nourishment of the west end (181+00- 250+00) template would again require approximately 185,000 yd3 every
5 years. Although the application states that the proposed project is not contingent on the authorization of the
current terminal groin application, the nourishment volume needed to replenish between baseline station 0+00
and 120+00 would be approximately 408,000 yd3 every 3 years without the terminal groin project or
approximately 400,000 yd3 every five years with the terminal groin project. The western portion of the CSDR
template (120+00 — 181+00) requires a contingent volume of approximately 60,000 yd3. The application states
that this area has not required any nourishment since the initial construction of the CSDR and periodic
nourishment is not anticipated to occur unless the area was impacted by a storm. The application does not
allocate any material for periodic nourishment between baseline station 250+00 and Tubbs Inlet. The proposed
project would disturb a maximum of approximately 4,763,000 ft2 of oceanfront beach, impacting areas below
and above Mean High Water (MHW) as a result of the nourishment activities. Placement of sand on the beach
would result in temporary mortality for intertidal micro fauna such as crabs and worms. Placement of material
below the MHW boundary would result in temporary turbidity within the nearshore waters of the Atlantic Ocean;
potentially affecting fish and aquatic life in the project area at the time. Limiting the work to the winter season
should reduce potential adverse impacts to fish communities. There may be some impact to sea turtle nesting
as a result of this project. Beach compaction should be monitored and tilling should be required to reduce the
likelihood of impacting sea turtle nesting and hatching activities. Erosion escarpments forming after the project
completion should also be leveled to reduce turtle nesting impacts. Public use of the beach during the beach till
process would be limited to some degree. The project would serve to provide authorization for the Town of
Ocean Isle Beach to continue periodic nourishment within limits of the existing CSDR template as well as
expand beach fill construction to the western portion of the Island. In addition, USACE-Disposal Area 300 has
been reserved for any non -compatible material that may be removed from the Shallotte Inlet Borrow Area.

The Town of Ocean Isle Beach (Town) is located on the southwestern coastline of Brunswick
County in southeastern North Carolina. The municipality is located on a barrier island, bordered
to the south by the Atlantic Ocean, to the north by the Atlantic Intracoastal Waterway (AIWW),
to the west by Tubbs Inlet and to the east by Shallotte Inlet. The Town of Holden Beach lies east
of Shallotte Inlet and the Town of Sunset Beach is located west of Tubbs Inlet. Ocean Isle Beach
is approximately 5.5 miles long and approximately 0.6 mi wide. The proposed project entails the
placement of beach compatible material along approximately 5,0 miles of the Town's oceanfront
shoreline. The borrow source for this material is located within Shallotte Inlet (Appendix A). The
island was incorporated in 1959 and has a current year-round resident population of
approximately 554 and a seasonal population of 25,000.

To understand the initiative behind the proposed 30 -Year Management Plan, it is helpful to
review the historical and current initiatives for managing shoreline erosion within Ocean Isle
Beach. The Town has implemented separate strategies for various portions of the shoreline; these
strategies were largely shaped by funding source and need. The following sections present the
management strategies for three sections of shoreline that include the easternmost end near the
Shallotte Inlet (East End), the central portion (Federal Coastal Storm Damage Reduction Project,
or CSDRP), and the westernmost end near Tubbs Inlet (West End).
East, ad
The easternmost 2,800 feet of the Town's shoreline, which includes approximately 1,000 feet of
shoreline with existing development and another 1,800 feet of undeveloped shoreline, was
excluded from the federal CSDRP due to projected high cost of periodic nourishment that would
be needed to counter the excessive erosion rates on the east end of the island. The high cost for
periodic nourishment along the east end of the island resulted in a low benefits to cost ratio (B/C)
that did not meet federal requirements that would have allowed the federal government to
participate in a storm damage reduction project in that area. The high rates of ocean shoreline
erosion on the east end of Ocean Isle Beach are associated with changes in the configuration of
the Shallotte Inlet ebb tide delta that, in turn, are driven by changes in the position and
orientation of the main ocean bar channel of the inlet.
In association with construction of the below discussed CSDRP, the USACE has periodically
deposited material on the east end, outside the federal project limits, since 2001. The material
removed from the AIWW and placed within this area has eroded quickly and has been
ineffective in slowing the rate of erosion. Additional measures undertaken by the Tgv,—m a"d""
private interests on the east end include placement of a sandbag revetment along 1,400 fea�`U
COASTAL PLANNING & ENGINEERING OF NORTH CAROLINA, INC,

shoreline, beginning at a point west of Shallotte Boulevard and extending east to the end of
development. This revetment was installed around 2005, and has recently been extended 400 feet
to the west (just past Charlotte Street). Some of the recent sandbag placement was accomplished
by NCDOT in an attempt to protect the eastern end of 2"d street.
Despite these previous efforts to mitigate the erosion along the Town's east end, five homes
have been lost since 2005, and between 20 and 25 parcels have become unbuildable due to the
inability to meet building setback requirements as dictated by the rules established by the NC
Coastal Resources Commission (CRC). Therefore, the Town is actively pursuing a separate
action to construct a terminal groin in proximity to Shallotte Inlet to provide added shoreline
protection to the easternmost end of the island. As proposed, construction of the terminal groin
will be accompanied by a small beach fill to create an accretion fillet immediately west of the
terminal groin. If constructed, the terminal groin will be located at station 0+00 (east of Shallotte
Blvd.) and is projected to provide a relatively stable beach west of the structure itself to
approximately baseline station 30+00, which is located about 280 feet west of Lumberton Street.
The results of the numerical modeling used to evaluate the potential impacts of the terminal
groin indicated the shoreline between the groin and baseline 30+00 would require approximately
2,000 cy/year of periodic nourishment to maintain the shoreline compared to almost 60,000
cy/year needed without the structure (CPE -NC, 2015). With the terminal groin project in place,
periodic nourishment volume needed to maintain the federal project would be reduced from
408,000 cy every three years to 400,000 cy every five years. The Town is pursuing the terminal
groin separately from the presently proposed 30 -Year Management Plan addressed in this permit
application. It should also be noted that the proposed action is not contingent on the authorization
or implementation of the terminal groin project.
The Town has worked with the U.S. Army Corps of Engineers (USAGE) since 1965 to plan and
implement a storm protection project for a large, central portion of its oceanfront shoreline. The
USACE's federal Coastal Storm Damage Reduction Project (CSDRP) spans 3.25 miles of the
Town's approximate 5.5 -mile oceanfront shoreline, from base station 10+00 at Shallotte
Boulevard to east Duneside Drive (baseline station 181+00) (Appendix A). The CSDRP includes
a 5,150 -foot long dune and berm section covering the beach from station 51+50 (located just
west of Raleigh St.) to 103+00 (located about halfway between Raeford St. and Lagrange St.), a
3,900 -foot transition on the east end, and a 7,800 -foot transition on the west end. The design
template within the main fill includes a dune with a crest elevation of +8.5 feet NAVD88 fronted
by a 50 -foot wide berm at elevation +6.0 feet NAVD88. The east and west transition have
variable width berms at elevation +6.0 feet NAVD88.
The initial construction of the federal project in 2001 involved placement of 1,866,000 cubic
yards of material obtained from a borrow area located in Shallotte Inlet. The borrow area was
also designated as a source for future periodic beach nourishment, which was scheduled to occur
every three years. The federal project has since been nourished twice, once in April/May 2010
and again in April 2014. Because the shoreline west of station 120+00 within the CSDRP
performed so well after the initial nourishment, this area has not needed re -nourishment
COASTAL PLANNING & ENGINEERING OF NORTH CAROLINA, INC.

Therefore, sand was not placed west of station 120+00 in the 2010 and 2014 periodic
renourishmem efforts. However, it is anticipated that periodic nourishment of the federal project
between station 120+00 and 181+00 will likely be required at some time in the future, either due
to gradual depletion of the fill, or loss during a coastal storm event.
The shoreline extending west of the federal project limits from station 180+00 to Tubbs Inlet is
currently unmanaged and has never received nourishment. The shoreline between station 181+00
(western limit of the federal CSDRP) and station 265+00 (located about 1,000 feet east of Tubbs
Inlet) has been relatively stable since 1997. The shoreline between stations 180+00 and 210+00
experienced a considerable amount of accretion following completion of the initial construction
of the federal CSDRP in March 2001, possibly due to the westward spreading of material place
for that project. This accretion continued to around October 2005. The westward spreading of the
nourishment material also appeared to extend west to about station 225+00. The accretion along
these shoreline segments diminished after 2006 with the shoreline position remaining essentially
stable until about May 2010. The shoreline between station 180+00 AND 250+00 experienced
additional accretion from May 2010 and August 2013. A similar increase was not observed
between stations 220+00 and 240+00, which is farther from the federal CSDRP.
The behavior of the shoreline on the westernmost end of the island between Tubbs Inlet and
baseline station 265+00 has been very erratic due to impacts the Tubbs Inlet ocean bar channel
has on the west end shoreline. The westernmost end will continue to be monitored, and if
shoreline conditions deteriorate in the future, consideration for remedial measures along this
section of shoreline may be warranted.

In May of 2015, the local stakeholders for five inlets on the southeast North Carolina coast
submitted a CAMA Major Permit application to the N.C. Department of Environment and
Natural Resources (NCDENR) Division of Coastal Management (DCM) for conducting
maintenance dredging for navigation. The Proposed Action consisted of maintenance dredging
and beneficial placement at five inlets and associated Atlantic Intracoastal Waterway (AIW W)
crossings: Bogue, New Topsail, Carolina Beach, Lockwoods Folly, and Shallotte River Inlet.
With the exception of Shallotte River Inlet, which is a federally -authorized Coastal Storm
Damage Reduction (CSDR) borrow area, these inlets are federally -authorized shallow -draft
inlets, and were referred to as "the SDI -5" in the application for convenience. The applicants
were the five local governments adjacent to the inlets, including the Town of Ocean Isle Beach,
who wished to obtain major LAMA permits to continue the ongoing federal navigation
maintenance dredging program at the inlets and the AIW W crossings, which is currently
conducted by the USACE Wilmington District.
Specifically, the proposed Shallow Draft Inlet project at Ocean Isle Beach included the
maintenance dredging from within AIW W crossings tangents 17-20 and from within the a 150',,
wide channel following deep water within Shallotte Inlet. Approximately 100,000 cubic yaxds-gf
COASTAL PLANNING & ENGINEERING OF NORTH CAROLINA, INC.
10

material from the AIW W crossing and approximately 65,000 cubic yards of material from within
Shallotte Inlet may be dredged per event. The beneficial placement of the material dredged from
these navigation features would then be placed within a 19,900' stretch of shoreline along Ocean
Isle Beach. Any given typical placement event, however, would extend approximately 2,800' in
length. It should be noted that unlike the other shoreline management projects discussed above,
the purpose of the dredging events associated with the SDI-5 permit is to maintain navigation.
The proposed action will include the placement of beach quality sand along approximately 5.0
miles of the Town's oceanfront shoreline. This encompasses the 3.25-mile extent already
included within the entirety of the USACE federal CSDRP and an additional 1.75 miles of
shoreline that extends from the western terminus of the CSDRP to Tubbs Inlet. Following initial
construction, maintenance events would be anticipated to occur every five years. The only
portion of the Town's oceanfront shoreline not included within this proposed action is the area to
the east of the CSDRP, which is currently under consideration for a terminal groin and associated
small beach fill project (Appendix A).
Beach quality sand would be dredged from the borrow area previously used by the USAGE
within Shallotte Inlet using a hydraulic pipeline dredge. Placement of beach quality sand onto the
beach would be accomplished via pipeline with direct pump-out, Once discharged, the sand will
be shaped and graded according to the design template using earth-moving equipment such as
bulldozers and excavators. Construction of the project and subsequent maintenance events would
occur within the environmental dredge window between November 15 and April 30.
The proposed 30-Year Management Plan would involve initial construction of the west end of
the island when needed and continued periodic nourishment of the reach that includes the federal
CSDRP should federal funding become unavailable. It is important to clarify that the
construction of the proposed terminal groin and the associated beach fill is not part of the 30-
Year Management Plan. The following sections provide a description of each component of the
island-wide plan.

The west end portion of the project refers to the shoreline extending from the western extent of
the federal CSDRP located at station 181+00 to Tubbs Inlet. The portion of the federal CSDRP
extending from station 70+00 to 180+00 has performed extremely well since initial construction
and has not required any periodic nourishment since initial construction. This section of the
federal CSDRP was therefore used as a proxy in developing the design template for the,•.....,, -.

CSDRP. The goal of the design is to increase the level of stone protection along the west end of
the island to a level comparable to that provided by the federal CSDRP.
Using data from June 2013 survey performed by engineering fine McKim & Creed, a
comparison was made of the volume material on the existing profiles within the federal CSDRP
limits to the volume of material on the profiles located west of the federal CSDRP. Based on this
comparison, a design template was developed that would provide the volume of material on each
west end profile comparable to the volume of material residing on the profiles within the federal
CSDRP between baseline stations 70+00 and 180+00. The design profile consists of a 10 -foot
wide dune at elevation +12.5 feet NAVD88 fronted by a 40 -foot wide berm at elevation +6.0 feet
NAVD88. The back or landward slope of the dune would be 1V:5H (1 Vertical to 5 Horizontal)
and the front or seaward slope IV: I OH.
The beach fill for the west end of Ocean Isle Beach would begin at the west end of the federal
project, located at station 181+00. A 400 -foot transition would be constructed between station
181+00 and 185+00 with the full design template extending between station 185+00 and
245+00. A 500 -foot transition would be constructed on the west end between station 245+00 and
250+00 in order to merge the project shoreline with the existing shoreline. A plan view showing
the limits of the proposed placement limits is provided in Appendix A. While the use of beach
fill along this reach may prove problematic given the dynamic influence of Tubbs Inlet, the
shoreline between 250+00 and Tubbs Inlet (approximately station 275+00) is included in the
proposed activities should future conditions warrant remedial measures.
Based on existing shoreline conditions, the section of shoreline between baseline station 250+00
and Tubbs Inlet would not be included in the initial construction of the beach fill project along
the west end of Ocean Isle Beach. Nevertheless, the condition of the shoreline along this extreme
west end of Ocean Isle Beach is highly dependent on the behavior of the ocean bar channel of
Tubbs Inlet and the influence of the bar channel on the configuration of the inlet's ebb tide delta.
Given the level of uncertainty of possible future shoreline conditions on the extreme west end of
Ocean Isle Beach, the proposed action includes possible future periodic nourishment of the
shoreline between baseline station 250+00 and Tubbs Inlet (approximately station 275+00).
The volume of material needed to construct the design template, including the two taper sections,
totals approximately 262,000 cubic yards, based on a June 2013 survey. In addition to this
volume, an additional 185,000 cy of material designated as advanced nourishment would be
placed seaward of the design template to account for anticipated volume losses during the time
interval between completion of initial construction and the first scheduled periodic nourishment
operation. In total, 447,000 cy of material would be placed during initial construction of the west
end.
Zslansounsnr_ne-, t
Periodic nourishment of the shoreline between station 0+00 to station 120+00 within the federal
CSDRP limits would require 80,000 cubic yards/year, or 400,000 cubic yards every 5 years.
COASTAL PLANNING & ENGINEERING OF NORTH CAROLINA, INC.

The western portion of the federal CSDRP (120+00 to 181+00) has not required any periodic
nourishment since construction and periodic nourishment of this section of the federal CSDRP is
not anticipated in the near future. However, given the possibility the area could be impacted by a
severe coastal storm, a nominal nourishment requirement of 2 cy/ft/yr for this section of the
federal CSDRP is recommended for planning purposes. Therefore, periodic nourishment of this
portion of the federal CSDRP could require an average of about 12,000 cy/yr, or 60,000 cy every
five years.
A five-year periodic nourishment interval would be implemented for the entire stretch of
shoreline extending from the proposed terminal groin (approximately station 00+00) to station
270+00. Using the annual rates provided above, the total five-year periodic nourishment
requirements for the Town of Ocean Isle Beach are estimated as follows:

The proposed 30 -Year Management Plan will utilize the existing federally approved borrow area
within Shallotte Inlet as the primary sand source for initial construction of the Town's west end
and for periodic nourishment of the federal CSDRP portion of the shoreline (Appendix A). This
borrow area extends from the Atlantic Intracoastal Waterway (AIWW) through the throat of the
channel and turns south over the ocean bar. Shallotte Inlet is an ebb -dominated system, with a
small flood delta and a much larger ebb tide delta. The original USAGE borrow area was
designed to have a maximum dredging depth of 15 ft. below MLW (-17.9 ft. NAVD), creating a
channel with 3H: IV sides slopes measuring approximately 950 ft. wide at the AIWW and 1,400
ft. wide at the bar channel. The footprint of the borrow area covers approximately 4.8 million sq.
ft. (I 10 ac).
Preliminary engineering and design work for the 2014 maintenance event used bathymetric data
collected by the USAGE in July and August 2013 to determine volumes within the borrow area.
At the time of the survey, approximately 1,312,000 cy of sand were available within the borrow
area. Based on project estimates provided by the Town of Ocean Isle Beach, approximately
800,000 cy were removed from the borrow area for the 2014 maintenance nourishment. Based on
past performance of the project, the borrow area is expected to re -charge due to shoaling of the
inlet complex.
Section (3)a of rule 15A NCAC .07H.0312 states that sediment completely confined to the

millimeters) sediment -is less than 10%. A geotechnical evaluation of the Shallotte Inlet borrow
area was presented in the Environmental Impact Statement (EIS) for the Ocean Isle Beach
terminal groin project. As indicated the EIS, an evaluation of vibracore data collected in 1998,
2005 and 2009 all show the sediment in the proposed borrow area meet these criteria. Composite
data for vibracores collected within the proposed borrow area in 1998 indicate the percent by
weight of fine-grained (less than 0.0625 millimeters) material is 1.3%. Composite data for those
vibracores within the proposed borrow area collected in 2005 and 2009 indicate the percent by
weight of fine-grained (less than 0.0625 millimeters) is 1.95%. The composite percent fine-
grained material for the existing beach sampled along the east end of Ocean Isle beach is 1.34%.
Analyses of the samples collected from the existing beach by CPE -NC and the USACE indicate
that sediment along the eastern end of Ocean Isle Beach has a mean grain size of 0.23mm. The
composite median grain size for the area analyzed using the 1998 vibracores is 0.16mm. The
composite mean grain size for the area analyzed using the 2005 and 2009 vibracores is 0.36mm.
Sediments recovered within the vertical boundaries of the proposed borrow area were described
by the USACE as having a tan and or gray color (USACE, 1997; Catlin, 2009). The wet
Munsell Color value ranges from 4 to 7, with a typical value of 5. The dry Munsell Color value
ranges from 6 to 8 with a typical value of 7. These characteristics represent the existing beach,
which is a composite of the characteristics of material that has been placed on the beach during
past nourishment projects and native beach sediment.
Although incompatible material has not been encountered within the Shallotte Inlet borrow area,
the applicant proposed to use USACE DA -300 as a contingency disposal location. It should be
noted that if incompatible material is encountered, contract language would direct the contractor
to move the dredge location. Should the Town pursue removal of any incompatible material, a
Consent Agreement would be obtained from the USACE prior to commencing any placement
within DA -300.
t;onsiruction Schedule
Project construction along the west end could occur as early as 2018 and therefore may be
performed in conjunction with the scheduled periodic nourishment of the federal CSDRP.
2.1.1,37 PurposeandiYeed
The Town is focused on a long-term shoreline management program. The Town's stated purpose
for implementing a beach nourishment project is to reduce the vulnerability of structures and
infrastructure, including roads and utilities, along the Town's oceanfront shoreline that could
become vulnerable through shoreline erosion over time. In addition, the proposed project would
serve to reduce the vulnerability of public infrastructure to storm -induced erosion. In order to
accomplish these goals, the Town is taking steps to maintain its oceanfront beach and dune to a
configuration that provides a reasonable level of storm damage reduction, flood reduction and
that mitigates long-term erosion that could threaten public and private development, recreational
opportunities and biological resources.

With implementation of the separately proposed terminal groin project (assuming it will be
permitted and constructed) and the existence of the federal CSDRP covering 3.25 miles of the
Town's shoreline, a large portion of the Town of Ocean Isle Beach will be considered managed,
Nevertheless, the Town has the following two concerns.
1) The portion of shoreline that encompasses the area between the western terminus of the
federal CSDRP and Tubbs Inlet remains unmanaged. Therefore, the Town is seeking
permits that would allow them to construct a non -federally funded beach nourishment
project along the umnanaged western shoreline. The nourishment project along the west
end of the island would include periodic maintenance events to preserve the design
template.
2) Obtaining federal funds for periodic nourishment of the CSDRP has become increasingly
difficult. This potential for federal -funding shortfalls has prompted the Town to seek
permits to use non-federal funds to provide periodic nourishment of the entire length of
the CSDRP.
The proposed action will allow the Town to construct the federal CSDRP should shortfalls in
federal funding occur and allow the Town to manage the currently un -managed shoreline to the
west of the federal CSDRP. Essentially, the goal is to allow the Town to manage its own
oceanfront shoreline, from the terminal groin to Tubbs Inlet, under one set of state and federal
permits.
