4h. Explain the purpose of the proposed project:*
The Carteret County Master Beach Nourishment Plan employs a regular and recurring cycle of nourishment events to continuously maintain beach profile sand volumes along 7
managed reaches (Bogue Inlet, Emerald Isle West, Emerald Isle Central, Emerald Isle East, Indian Beach/Salter Path, Pine Knoll Shores, and Atlantic Beach). Nourishment events would
be implemented according to 25 -year level of protection (LOP) beach profile volumetric triggers, ranging 211-266 cubic yards per foot along various reaches of the approximately 23 -mi
project shoreline. Maintenance of the 25 -year LOP beach profile volumes along the management reaches, which equates to protection for upland structures against a 25 -year storm
event, would involve: 1) regular recurring "maintenance" nourishment events to offset long-term, chronic background erosion (including hotspot erosion), and 2) periodic "storm
response' nourishment events to offset sand losses incurred during hurricanes or major storm events. The individual management reaches are expected to require recurring
maintenance sand placements at varying intervals to offset chronic background erosion. Each individual nourishment event will be unique based on various factors, including storm
related erosion.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The Post -Florence Renourishment Project — Phase II will take place during the winter 2019/2020 (base project) and winter 2020/2021 (option project) construction windows (November
16 — April 30). Due to funding constraints (currently awaiting award of FEMA reimbursement) and total project volume required to make up for losses from Hurricane Florence, it is
anticipated that construction will require two dredging windows to complete. The total project calls for 4,221,900 cy of material to be placed along 21 miles of oceanfront shoreline,
spanning 10 nourishment reaches in Emerald Isle, Indian Beach, Salter Path, Pine Knoll Shores, and Atlantic Beach.
Approximately 5,066,280 cy of beach compatible material is expected be dredged from portions of the Current and Old ODMDS to account for losses (20%) between dredging and
placement. The attached event notification presents an overview of the total project extents, reach locations, reach lengths, volumes, and borrow area location. The "Base" project, to
be constructed during winter 2019/2020, consists of 1,995,000 cy of material to be placed along 9.5 miles of shoreline. The "Option" project, to be constructed during winter 2020/2021,
consists of 2,226,900 cy of material to be placed along 11.5 miles of shoreline. Project plans are provided in Attachment A. Slight adjustments in volume may be made prior to
construction based on bid prices and pre -construction surveys. These adjustments could raise the project volume by up to 20%. These adjustments will be discussed in the pre -
construction meeting with State and Federal agency representatives.
Plans call for a base project to be constructed during the winter 2019/2020 dredging window consisting of 1,995,000 cy of material to be placed along 9.5 miles of shoreline consisting
of four nourishment reaches in Emerald Isle (Reach 2), Salter Path (Reach 7), Pine Knoll Shores (Reach 9), and Atlantic Beach (Reach 10). The average fill density will range from 35 —
40 cy/ft across each of the four reaches however it is expected that the fill density will vary between 25 cy/ft and 50 cy/ft within each reach. The template will consist of a dune of variable
height ranging from 10 ft to 14 ft NAVD88 and variable width generally ranging from 20 ft to 50 ft. In most cases, the landward dune tie in will be constructed to tie in at the dune crest
elevation. In cases where the existing vegetation line is belowthe dune crest, the landward dune tie in will be constructed with a 5:1 back slope down to the existing vegetation elevation.
A seaward 5:1 dune slope will be constructed from the dune crest down to a berm of variable width generally ranging from 45 ft to 90 ft at a variable elevation ranging from 6 to 6.5 ft
NAVD88. A 20:1 berm slope will be constructed down to tie in with the existing ground offshore between elevation -4 and -10 ft NAVD88. Approximately 2,394,000 cy of beach
compatible material is expected be dredged from portions of the Current and Old ODMDS to account for losses between dredging and placement (20%).
The option project will be constructed during the winter 2020/2021 dredging window pending receipt of reimbursement funds from FEMA. The option project consists of 2,226,900 cy of
material to be placed along 11.5 miles of shoreline consisting of six nourishment reaches in
Emerald Isle (Reach 1, Reach 3, Reach 4, and Reach 5) and Indian Beach/Salter Path (Reach 6 and Reach 8). The average fill density will range from 30 — 45 cy/ft across each of the
six reaches however it is expected that the fill density will vary between 25 cy/ft and 50 cy/ft within each reach. The template in Reaches 1, 3, and 4 will consist of a dune of variable
height ranging from 10 ft to 14 ft NAVD88 and variable width generally ranging from 20 ft to 50 ft. In most cases, the landward dune tie in will be constructed to tie in at the dune crest
elevation. In cases where the existing vegetation line is below the dune crest, the landward dune tie in will be constructed with a 5:1 back slope down to the existing vegetation elevation.
A seaward 5:1 dune slope will be constructed down to a berm of variable width generally ranging from 45 ft to 90 ft at a variable elevation ranging from 6 to 6.5 ft NAVD88. A 20:1 berm
slope will be constructed down to tie in with the existing ground offshore between elevation -4 and -10 ft NAVD88. The dune in Reaches 5, 6, and 8 was previously constructed during
the Post -Florence enourishment Project — Phase I (winter 2019). Therefore, these reaches will consist of a berm only extension of variable width generally ranging from 45 ft to 90 ft at a
variable elevation ranging from 6 to 6.5 ft NAVD88.
Approximately 2,672,280 cy of beach compatible material is expected be dredged from portions of the Current and Old ODMDS to account for losses between dredging and placement
(20%). As shown in the attached plans and event notification, Figure 1-2 through Figure 1-5 present typical cross-section and plan views for the areas to be nourished during the Post -
Florence Renourishment Project — Phase II. Figure 1-2 presents typical cross sections for reaches where a dune and berm are to be constructed (Reaches 1, 2, 3, 4, 7, 9, and 10).
Figure 1-3 presents a typical cross section for reaches where only a berm is to be constructed (Reaches 5, 6, and 8). These typical cross section and plan views were developed based
on the newest May 2019 survey data. Slight adjustments in the design template may be made prior to construction based on bid prices and pre -construction surveys. These
adjustments will be discussed in the pre -construction meeting with State and Federal agency representatives.
The Post -Florence Renourishment Project — Phase II to be performed in Winter 2019/2020 and Winter 2020/2021 will use a hopper dredge to obtain material from the Current and Old
ODMDS where it will then be transported to an offshore temporary mooring and submerged pipeline near the project site. A pre -construction survey of the submerged pipeline crossing
Will be provided to state and federal agencies prior to construction. The hopper dredge will then connect to the pipeline and pump the material from the hopper to the beach where the
sand is spread mechanically by bulldozers. This is the same type of dredging placement operation used during the Phase I project (2019) as well as multiple historical projects (Phase 1
and 2 of the Bogue Banks Beach Nourishment Project (2001/2002 and 2002/2003), Post-Ophelia (2007) and Post -Irene (2013)).

Nourishment events would be implemented according to 25 -year level of protection (LOP) beach profile volumetric triggers, ranging 211-266 cubic yards per foot along various reaches
of the approximately 23 -mi project shoreline. Maintenance of the 25 -year LOP beach profile volumes along the management reaches, which equates to protection for upland structures
against a 25 -year storm event, would involve: 1) regular recurring "maintenance" nourishment events to offset long-term, chronic background erosion (including hotspot erosion), and 2)
periodic "storm response" nourishment events to offset sand losses incurred during hurricanes or major storm events. The individual management reaches are expected to require
recurring maintenance sand placements at approximate intervals of 3 years (Emerald Isle East), 6 years (Pine Knoll Shores, Indian Beach/Salter Path, Bogue Inlet), and 9 years
(Emerald Isle Central, Emerald Isle West) to offset chronic background erosion. Each individual nourishment event will be unique based on various factors; however, based on current
projections and timelines, the range of days per event could be 50-250 days with most events being 100-150 days.

4h. Comments:
The borrow area is the same as was used for the Post -Florence Renourishment Project — Phase I
(spring 2019). The borrow area covers approximately 773 acres, with 218 acres located in the
Current ODMDS in Federal waters and 555 acres located in the Old ODMDS in State waters.
Based on the after dredge survey taken in May 2019, there is approximately 10,772,643 cy of
beach compatible material remaining above -52 ft NAVD88 within the borrow area which is
permitted for a maximum dredge depth of -50 ft NAVD88 with 2 ft allowable overdredge.
Approximately 8,197,365 cy of material is available in the State-owned portion of the borrow area
and approximately 2,575,278 cy of material is available in the BOEM controlled Federal portion
of the borrow area. Figure 1-6 presents the current borrow area bathymetry and available volumes.
It should be noted that the County's BOEM lease agreement allows for the dredging of 2,000,000
cy of material over a 3 -year period that began with the construction of the Post -Florence
Renourishment Project — Phase I in spring 2019. Based on before and after dredge surveys, it is
estimated that only 136,449 cy of material was dredged from Federal waters during the Phase I
project, leaving approximately 1,863,550 cy of material available for use during the Post -Florence
- Phase II project.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The Post -Florence Renourishment Project — Phase II is a continuation of the first project (Post -
Florence Renourishment Project — Phase 1) completed under the Bogue Banks Master Beach
Nourishment Plan. Pursuant to the National Environmental Policy Act (NEPA), the environmental
effects of implementing the Bogue Banks Master Beach Nourishment Plan have been evaluated in
an Environmental Impact Statement (EIS). The Final EIS (FEIS) was distributed to state and
federal agencies and a Record of Decision issued in 2018.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Permit conditions include dredge window restrictions, dredge cut depth restrictions, sediment
compatibility, and endangered species takes. Measures will be taken by the engineer and
contractor to meet each of these requirements. Beach construction and use of heavy equipment on
the beach will be limited to the November 16 — April 30 time period for placement of beach
material. Dredging in the borrow area will not exceed -52 ft NAVD88. Plans and specifications
will indicate a maximum dredge depth of -50 ft NAVD88 plus 2 ft allowable overdredge. The
large borrow area, containing ample material, will keep individual dredge cut depths to a
minimum. The maximum dredge cut for the Post -Florence Renourishment Project - Phase I was
approximately 7-8 ft and that is expected to remain for the Phase II project. In addition,
undisturbed areas will be left to allow for recovery of benthic resources. Weekly sediment
sampling will be performed by a third party laboratory analysis to ensure grain size and color are
beach compatible. Daily onsite visual assessment of sediment compatibility will also be conducted
by the contractor.
The County may require relocation trawling for the entire length of the project regardless of
whether the mandatory trawling triggers have been met (i.e. water temperature, lethal take).
Endangered species monitoring will be implemented on both the dredge and the trawler, when
working, for the entire length of the project.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State

ATTACHMENT B
Typical Dune Planting Procedures
Dune Planting Operational Plan
Post -Florence Renourishment Project — Phase II
Planting Project Schedule:
Dune planting is highly dependent upon weather conditions for new plants and time to allow
newly pumped beach sands to wash free of salts prior to planting starting. This requires a fair
amount of rain to wash the newly placed material to reduce the amount of natural sea salts in the
material when pumped ashore using ocean water.
The daily hours of operation on the beach will begin once the permitted turtle monitor provides
clearance of the beach and specific work footprint locations for the day. The turtle survey
generally finishes at a set time daily (typically by 7:30 am) depending on the locale and local
volunteers, first point of entry on the beach will be 30 minutes after patrols are completed. 8 am
is generally a practical time to show up and expect turtle coordination and communication to be
complete. The day generally lasts 8 to 10 hours, but equipment and personnel will be off the
beach before dusk.
Typical Equipment:
Hand flantiLig 0Aerations
Tractor- John Deere 5085 or equivalent
Wagon — 1,000 -gallon nurse tank with pump
Hoses - Typical 5/8" garden hoses
Pipe - 3/4 inch pipe with water valve
ATV/light-weight pickup truck
Mechanical flantiLig 0Aerations
Tractor - John Deere 5085 or equivalent with mounted water tank
Planter - Mechanical Transplanter 580 (2 row machine)
Typical Daily Routine of Operations:
Once the all clear is given from turtle patrol staff will enter the beach with the equipment planned
to be used for the while day of work. The tractor drives as close to; or in wet sand, by the water,
until reach the planting site (footprint) for the day. Typical driving speed is less than 5 MPH for
public safety. A company 4x4 truck or ATV travels in front of the tractor approximately 100-200
feet ahead of the work vehicles, to shuffle tourists and property from the path of the tractor, and
to look for hazards, such as holes dug by tourist, possible false crawl turtle tracks, escarpments,
etc.
Once adjacent to the work area, the upper dune is accessed using the shortest possible lateral
distance to the dune, to limit creating ruts in soft sand or damaging the slope of the dune face.
Once on the dune with the mechanical transplanter or other hand planting equipment, all
equipment will stay on the dune until operations are finished for the day. The equipment will then
be moved off the beach in the afternoon following the same procedure as entry and exit at the
closest access to the work. All equipment will be stored off beach during periods of weather or
non -planting (night).
If hand planting, the tractor and water wagon will arrive and traverse the beach, as discussed
above, but at the work area, will stop within 20 feet of the toe of the dune, or wherever tourist and
tents allow, but always greater than 20 feet. The watering hoses are then able to be utilized 100
feet to the front of tractor, and 100 feet to the rear of wagon, so basically planting can cover this
200 -foot area, where water can be supplied during planting. This 200 -foot watering step set
continues until complete with a planting footprint. Once complete in that area then the tractor
pulls forward another 200 foot and the process start again. If the water tank runs out of water the
tractor and wagon exit the beach, as it entered, and re -fills and returns the same as previous
ingress and egress. At the end of the day the tractor and water wagon, as well as all other planting
equipment are stored off beach at night.
Mechanical Transplanter Operations:
The transplanter is pulled by the tractor, same as the water tank, down the beach and
mechanically places a plant at a calibrated spacing as the tractor moves forward. The plant
fingers are driven by a rubber flotation tire that rolls on the sand surface and a chain drives the
disk to which plant fingers are attached. These fingers release the plants at a depth of 8 inches and
a shoe pushes the soil back around the plant and closes the hole. The planter has been modified to
drop the fertilizer and water, required at each plant location, at the same time as the plant drops.
The tractor can pull 2 individual planter units at a time and they are spaced on a `tool bar' for the
spacing requirements (21 inches).
The number of passes required to finish each section will vary from location to location,
depending on the depth of the dune. The planter can only be used on flat surface sand, so a typical
planter placement sets of will consist of 6, 12, 18, 24, or 30 rows based on the width of the upper
dune from existing veg to frontal slope. Most places for this project will be 18 to 24 rows.
The speed of the tractor when pulling the transplanter and actively planting is 1.5 to 2 MPH. Most
people can out walk the operation.
The tractor will access the dune crest by direct line, same as stated above in hand planting, so no
damage to the dune is done. If the dune is steep, we may angle up slope to be sure no rutting or
damage is done. If needed, rubber mats can also be used to gain traction without damage to the
dune face in order to access the upper dune. These mats are temporary and are immediately
removed once the equipment is topside of the dune.
The tractor and transplanter will transverse the beach one round trip per day. The tractor and
water barrel will transverse on average three round trips per day to support the higher volume of
planting when using the transplanter.
The typical number of plant set moves in a day would be 2 if used without the mechanical planter
and 5 if used in conjunction or after use of the mechanical planter.
Conservation Measures
1.) No entry onto beach is allowed prior to 8 am. This gives Turtle patrol time to
complete rounds and report and flag any located nest. If no calls are received, or if
the calls indicate nest outside of the planting areas then access to the beach and crews
proceed to the worksite. A work truck proceeds in front of the tractor to check for
nest/crawls and clear tourist and property from the tractor path. Prior to dune access
work crews will walk the entire length of the planned planting worksite to look for
any sign of turtles or false crawls that may not have been reported.
2.) Daily worksites will be indicated with plants from previous days work on one side
and a PVC stick painted red on the other side of the area to be planted for the next
day. This stake will be located at the top of the dune crest. Turtle monitors will thus
know where work will commence the following day and focus on potential turtle
activity in that area.
3.) Point of contact information for the on-site quality control leader and all contractors
will be provided prior to commencement of project construction.
4.) The tractor and water tank will be run in wet sand whenever possible. The only time
that would not happen is when it must be moved at dead high tide. Due to tourist
populations this is almost never done. We can work around those extreme tide
periods by refilling prior to tides or waiting to enter beach until a waning tide.
5.) When possible, trips to and from the beach access points will be eliminated by
accessing water sources directly on the beach. This eliminates trips, beach tracking,
and speeds up the work. This generally requires utility, municipal, and private
homeowner cooperation.
6.) Tire pressures in all equipment are run at the lowest possible setting to reduce PSI
without damaging tires. This not only reduces compaction but also increases traction
for all equipment.
7.) The mechanical transplanter will (can only) be used in the area above the 12 -foot
dune crest. Only relatively flat beach can be planted using this method. The
remaining areas of the dune slope and tie against the existing dune vegetation line
must be hand planted.
8.) Prior to work every day the work crew will walk the entire area to be planted that day
to look for turtle nest. During the planting operation the tractor driver will look for
turtle crawl signs as proceeding forward with the planter.
9.) No mechanical planting work will be performed within 50 ft of any marked turtle
nest or hand planting within 20 ft of any marked turtle nest.

Subject: Bogue Banks Master Beach Management Plan
Request for Concurrence and Initiation of Consultation
Carteret County, NC
Action ID No. SAW -2009-00293
Dear Mr. Sugg:
This letter acknowledges the U.S. Fish and Wildlife Service's (Service) September 18,
2017 receipt of your September 12, 2017 letter requesting initiation of formal section 7
consultation under the Endangered Species Act. The consultation concerns the possible
effects of the proposed Bogue Banks Master Beach Management Plan on the West Indian
manatee (Trichechus manatus), piping plover (Charadrius melodus) and piping plover
critical habitat, red knot (Calidris canutus r fa), seabeach amaranth (Awaranthus
pumilus), and the loggerhead (Caretta caretta), leatherback (Dermochelys coriacea),
green (Chelonia mydas), hawksbill (Eretmochelys imbricata), and Kemp's ridley
(Lepidochelys kempir) sea turtles, and terrestrial critical habitat for loggerhead sea turtles.
The Service reviewed the Draft Environmental Impact Statement (DEIS) and provided
comments through the Department of the Interior on June 12, 2017. In addition, the
Service discussed the project by phone and email with the Corps on several dates, most
recently October 2, 2017.
For this project, the Corps is the lead agency and BOEM is a cooperating agency. There
are multiple sand sources proposed, including the old and current Ocean Dredged
Material Disposal Sites (ODMDS), Area Y, 10 Atlantic Intracoastal Waterway (AIWW)
disposal areas, and six upland sand sources (sand mines or borrow pits). Outer
Continental Shelf (OCS) sand resources Iocated within the Current ODMDS borrow area
2
are proposed to be dredged for the Bogue Banks project. BOEM's proposed action is to
issue a negotiated agreement authorizing use of the sand resource areas at the request of
the local sponsor (authorized under 43 United States Code (U.S.C.) 1337 (k) (2)). This
action is related to, but unique from, the locality or Corps' proposed action.
The Service has received all of the information necessary to initiate formal consultation,
as outlined in the regulations governing interagency consultations (50 CFR §402.14).
The Service concurs with the Corps' determinations for all species listed in the BA. It is
the Service's opinion that as proposed, the placement of sand may be covered by the
August 28, 2017 Statewide Programmatic Biological Opinion (SPBO), with some
clarification of the Terms and Conditions (discussed below). The SPBO may also cover
sand placement as an associated action of sand extraction from the OCS authorized by
BOEM. If the Corps intends that the project be covered under the SPBO, please send a
written request for our agreement. Alternatively, the intention to cover the project under
the SPBO may be outlined in a public notice for the project, to which the Service will
respond.
Term and Condition A.15 of the BO states:
A.15. Only beach compatible fill shall be placed on the beach or in any associated dune
system. Beach compatible fill must be sand that is similar to a native beach in the
vicinity of the site that has not been affected by prior sand placement activity. Beach
compatible fill must be sand comprised solely of natural sediment and shell material,
containing no construction debris, toxic material, large amounts of rock, or other foreign
matter. The beach compatible fill must be similar in both color and grain size distribution
(sand grain frequency, mean and median grain size and sorting coefficient) to the native
material in the Action Area. Beach compatible fill is material that maintains the general
character and functionality of the material occurring on the beach and in the adjacent
dune and coastal system. In general, fill material that meets the requirements of the most
recent version of the North Carolina Technical Standards for Beach Fill (15A NCAC 07H
.0312) is considered compatible.
The Service believes that DEIS and the BA do not adequately describe the Munsell color
of the native beach or the sand material to be placed on the beach. In previous
nourishment activities using the proposed sand sources, dark sand was an issue, as was
elevated temperatures of turtle nests. Large amounts of shell was also an issue for at least
one sand placement event. According to information in your October 2, 2017 email and
phone conversations with Kathy Matthews, the dark sands came from Borrow Areas A1,
A2, B l a, B l b, B 1 c, and B2, which are not currently proposed for this project. However,
Appendix A of the DEIS states that some of the sediment in the ODMDS and Borrow
Area Y are "dark," with little additional description. Munsell color in particular, and
color in general, is not discussed for the majority of the sand sources. Therefore, the
data remain insufficient to assure that the sediment proposed for placement on the beach
(particularly from the ODMDS and Borrow Area Y) will be compatible with respect to
color, as well as percent of shell, fines, or gravel. Section 4.4 states that the majority of
Borrow Area Y is not compatible, and that the sediment is "dark in color." For sediment
characteristics other than color, the Service will defer to the state sediment criteria. There
are no established criteria for color.
Wet sand with a value of less than 5 (for example, hues of 10 YR, 7.5 YR, 5Y or 2.5Y
with a value below 5) would be darker than what the Service considers acceptable for
normal sea turtle incubation, because the darker color may cause higher incubation
temperatures and greatly skew the sex ratio towards female (Mrosovsky et al. 1984,
Mrosovsky & Provancha 1992). We understand that color monitoring of the material
dredged from the navigation channel and the ODMDS has been conducted in the past,
and that the material was found to be compatible. However, at least some of the other
sites currently have relatively unknown compatibility.
Therefore, the Service has the following recommendations to clarify the requirements of
the SPBO.
1. In order to comply with the sediment compatibility Terms and Conditions in the
SPBO, the applicant should provide to the Corps and the Service additional geotechnical
data prior to each sand placement event, including a description of the wet sand Munsell
color of the native beach and of the proposed sand source. Some of the sand sources
appear to have a greater amount of existing geotechnical information, and so the amount
of additional data needed may vary based upon the existing available information.
Generally, a wet sand value of less than 5 should not be considered compatible. We note
that based upon future data on the hue/value/chroma of the native beach, a value of 5 or
higher may also be considered incompatible in comparison.
2. There is a general belief on the part of some agencies that darker -colored materials
often "bleach out" within a few months, and therefore do not pose a compatibility
problem. However, the Service has not seen any studies to support this belief. If
incompatibly -dark sediments are placed in the project area during the life of the permit,
the Service recommends that, among other remedial actions, the sand be monitored for
three years (or until the sand is no longer on the beach, whichever comes first) to
determine the depth to which "bleaching" occurs over the 3 -year period and the effect, if
any, on temperature of sea turtle nests. A study plan should be submitted to the Service
for review and approval before the bleaching and temperature monitoring begins.
If you have any questions or concerns about this consultation or the consultation process
in general, please feel free to contact Kathy Matthews at 919-856-4520, ext. 27 or by e-
mail at <kathryn_matthews@fws.gov >.
Sincerely,
Peter Benjamin

BOGUE BANKS MASTER BEACH NOURISHMENT PLAN
POST -FLORENCE PHASE II EVENT NOTIFICATION
1.0 POST -FLORENCE PHASE II PROJECT DESCRIPTION
1.1 Project Overview
The Post -Florence Renourishment Project — Phase II will take place during the winter 2019/2020
(base project) and winter 2020/2021 (option project) construction windows (November 16 —April
30). Due to funding constraints (currently awaiting award of FEMA reimbursement) and total
project volume required to make up for losses from Hurricane Florence, it is anticipated that
construction will require two dredging windows to complete. The total project calls for 4,221,900
cy of material to be placed along 21 miles of oceanfront shoreline, spanning 10 nourishment
reaches in Emerald Isle, Indian Beach, Salter Path, Pine Knoll Shores, and Atlantic Beach.
Approximately 5,066,280 cy of beach compatible material is expected be dredged from portions
of the Current and Old ODMDS to account for losses (20%) between dredging and placement.
Figure 1-1 presents an overview of the total project extents, reach locations, reach lengths,
volumes, and borrow area location. The "Base" project, to be constructed during winter
2019/2020, consists of 1,995,000 cy of material to be placed along 9.5 miles of shoreline. The
"Option" project, to be constructed during winter 2020/2021, consists of 2,226,900 cy of material
to be placed along 11.5 miles of shoreline. Project plans are provided in Attachment A. Slight
adjustments in volume may be made prior to construction based on bid prices and pre -construction
surveys. These adjustments could raise the project volume by up to 20%. These adjustments will
be discussed in the pre -construction meeting with State and Federal agency representatives.

1.2 Project Template
Plans call for a base project to be constructed during the winter 2019/2020 dredging window
consisting of 1,995,000 cy of material to be placed along 9.5 miles of shoreline consisting of four
nourishment reaches in Emerald Isle (Reach 2), Salter Path (Reach 7), Pine Knoll Shores (Reach
9), and Atlantic Beach (Reach 10). The average fill density will range from 35 — 40 cy/ft across
each of the four reaches however it is expected that the fill density will vary between 25 cy/ft and
50 cy/ft within each reach. The template will consist of a dune of variable height ranging from 10
ft to 14 ft NAVD88 and variable width generally ranging from 20 ft to 50 ft. In most cases, the
landward dune tie in will be constructed to tie in at the dune crest elevation. In cases where the
existing vegetation line is below the dune crest, the landward dune tie in will be constructed with
a 5:1 back slope down to the existing vegetation elevation. A seaward 5:1 dune slope will be
constructed from the dune crest down to a berm of variable width generally ranging from 45 ft to
90 ft at a variable elevation ranging from 6 to 6.5 ft NAVD88. A 20:1 berm slope will be
constructed down to tie in with the existing ground offshore between elevation -4 and -10 ft
NAVD88. Approximately 2,394,000 cy of beach compatible material is expected be dredged from
portions of the Current and Old ODMDS to account for losses between dredging and placement
(20%).
The option project will be constructed during the winter 2020/2021 dredging window pending
receipt of reimbursement funds from FEMA. The option project consists of 2,226,900 cy of
material to be placed along 11.5 miles of shoreline consisting of six nourishment reaches in
Emerald Isle (Reach 1, Reach 3, Reach 4, and Reach 5) and Indian Beach/Salter Path (Reach 6
and Reach 8). The average fill density will range from 30 — 45 cy/ft across each of the six reaches
however it is expected that the fill density will vary between 25 cy/ft and 50 cy/ft within each
reach. The template in Reaches 1, 3, and 4 will consist of a dune of variable height ranging from
10 ft to 14 ft NAVD88 and variable width generally ranging from 20 ft to 50 ft. In most cases, the

5, 6, and 8 was previously constructed during the Post -Florence Renourishment Project— Phase I
(winter 2019). Therefore, these reaches will consist of a berm only extension of variable width
generally ranging from 45 ft to 90 ft at a variable elevation ranging from 6 to 6.5 ft NAVD88.
Approximately 2,672,280 cy of beach compatible material is expected be dredged from portions
of the Current and Old ODMDS to account for losses between dredging and placement (20%).
Figure 1-2 through Figure 1-5 present typical cross-section and plan views for the areas to be
nourished during the Post -Florence Renourishment Project — Phase II. Figure 1-2 presents typical
cross sections for reaches where a dune and berm are to be constructed (Reaches 1, 2, 3, 4, 7, 9,
and 10). Figure 1-3 presents a typical cross section for reaches where only a berm is to be
constructed (Reaches 5, 6, and 8). These typical cross section and plan views were developed
based on the newest May 2019 survey data. Slight adjustments in the design template may be
made prior to construction based on bid prices and pre -construction surveys. These adjustments
will be discussed in the pre -construction meeting with State and Federal agency representatives.

1.3 Borrow Area Overview
The borrow area is the same as was used for the Post -Florence Renourishment Project- Phase I
(spring 2019). The borrow area covers approximately 773 acres, with 218 acres located in the
Current ODMDS in Federal waters and 555 acres located in the Old ODMDS in State waters.
Based on the after dredge survey taken in May 2019, there is approximately 10,772,643 cy of
beach compatible material remaining above -52 ft NAVD88 within the borrow area which is
permitted for a maximum dredge depth of -50 ft NAVD88 with 2 ft allowable overdredge.
Approximately 8,197,365 cy of material is available in the State-owned portion of the borrow area
and approximately 2,575,278 cy of material is available in the BOEM controlled Federal portion
of the borrow area. Figure 1-6 presents the current borrow area bathymetry and available volumes.
It should be noted that the County's BOEM lease agreement allows for the dredging of 2,000,000
cy of material over a 3 -year period that began with the construction of the Post -Florence
Renourishment Project - Phase I in spring 2019. Based on before and after dredge surveys, it is
estimated that only 136,449 cy of material was dredged from Federal waters during the Phase I
project, leaving approximately 1,863,550 cy of material available for use during the Post -Florence
- Phase II project.

Again, while the total project placement volume is estimated to be 4,221,900 cy, due to losses
incurred between dredging and placement (20%), it is expected that 5,066,280 cy may be dredged
from the borrow area. Figure 1-7 and Figure 1-8 present the site plan and typical cross sections
for the proposed borrow area located in the Current and Old ODMDS.

1.4 Sediment Compatibility
As discussed, the Post -Florence Renourishment Project— Phase II will use a borrow area within
the Current and Old ODMDS that was previously used for the Post -Florence Renourishment
Project — Phase I_ Sediment analysis was previously performed as part of the development of the
Bogue Banks Master Beach Nourishment Plan and the borrow area has been proven to contain
compatible material as the Federal portion was used during the Post -Irene Renourishment Project
in 2013 and the Post -Florence Renourishment Project — Phase I utilized both State and Federal
portions of the borrow area in 2019. Figure 1-9 shows the location of the analyzed vibracores
within the borrow area.
Figure 1-9: Potential Borrow Areas Within the Current and Old ODMDS
Based on analysis of the native beach sediment data from 64 samples (16 transects) investigated
by CSE in 2001, a median grain size of 0.3 mm was selected as the best representation of the native
beach. The native beach characteristics and fill requirements established for the project are
presented in Table 1-3.

In addition, Moffatt & Nichol conducted a field investigation on May 24, 2018 to estimate the total
number of sediments and shell material greater than or equal to three inches in diameter, observable
on the surface of the beach between mean low water and the frontal dune toe, in a 50,000 square
foot area. Investigations were performed in two locations, one in Atlantic Beach between
Transects 78 and 80 and one in Emerald Isle between Transects 29 and 30. The Atlantic Beach
investigation area has never been nourished and the Emerald Isle investigation area has only been
nourished once. Results of the investigation found 138 pieces of shell material greater than or
equal to three inches in diameter at Atlantic Beach and 211 pieces of shell material greater than or
equal to three inches in diameter at Emerald Isle.
Vibracores within the borrow area were analyzed with respect to parameters as presented in Table
1-3 to determine the quantity and depth to which beach compatible material exists within the
borrow area. Table 1-4 presents the sediment characteristics of the vibracores within the potential
borrow areas. Based on analysis of these vibracores, it is estimated that beach compatible material
exists down to an elevation of —52 ft NAVD88. Thus, plans will specify a dredge depth of -50 ft
NAVD88 with 2 ft of allowable overdredge. Volume calculations indicate 2,575,278 cy of
material exists above —52 ft NAVD88 in the potential borrow area within the Current ODMDS
and 8,197,365 cy of material exists above -52 ft NAVD88 in the potential borrow area within the
Old ODMDS (see Figure 1-6). Therefore, the total volume available from the potential borrow
areas is 10,772,643 cy. While 4,221,900 cy is the expected placement volume, the anticipated
dredge volume could reach 5,066,280 cy due to losses typically incurred between what is dredged
and what is placed (20%).
Weekly sampling will be performed, subject to laboratory analysis, to ensure sediment
compatibility throughout the project.

1.5 Dune Planting
Dune planting will be conducted on the dune crest and approximately half way down the dune
slope to ensure dune stability over all tidal cycles. Project specifications, similar to what was
implemented during the Phase I project, will include the planting of native sea oats and bitter
panicum on a 24 -inch grid spacing. Due to plant germination and temperature growing
requirements, it is likely that dune planting will not commence until late March during each
construction window. During the turtle nesting window, certified sea turtle volunteers will walk
the beach each morning (before 8 am) before planting begins to identify sea turtle nests and/or
false crawls. Planting buffers of 50 ft (mechanical planting) and 20 ft (hand planting) will be
applied in locations where nests were identified within the project placement area. Typical dune
planting operations are provided in Attachment B and will be coordinated with the State and
Federal resource agencies.
Current guidelines allow for the use of heavy equipment on the beach (tractors, trailers, mechanical
planters, etc.) until April 30th. After April 30th, equipment usage is restricted to light duty vehicles
(ATVs and pick-up trucks), thereby requiring hand planting methods. ATVs are allowed to
traverse the beach on wet sand and park on dry sand below the base of the dune. Pick-up trucks
are only allowed to traverse and park on wet sand below the high tide line (wrack line).
The County wishes to continue consultation with FWS to amend the guidelines to allow the use of
heavy equipment (tractors, trailers with water tanks, and mechanical planters) on the beach after
April 30th in order to significantly reduce the amount of time required to complete the planting.
The County is willing to take on additional conservation measures to ensure the safety of turtle
nests.
1.6 Methods of Construction
The Post -Florence Renourishment Project — Phase II to be performed in Winter 2019/2020 and
Winter 2020/2021 will use a hopper dredge to obtain material from the Current and Old ODMDS
where it will then be transported to an offshore temporary mooring and submerged pipeline near
the project site. A pre -construction survey of the submerged pipeline crossing will be provided to
state and federal agencies prior to construction. The hopper dredge will then connect to the
pipeline and pump the material from the hopper to the beach where the sand is spread mechanically
by bulldozers. This is the same type of dredging placement operation used during the Phase I
project (2019) as well as multiple historical projects (Phase 1 and 2 of the Bogue Banks Beach
Nourishment Project (2001/2002 and 2002/2003), Post-Ophelia (2007) and Post -Irene (2013)).
2.0 ENVIRONMENTAL DOCUMENTATION AND AGENCY
COORDINATION
The Post -Florence Renourishment Project — Phase II is a continuation of the first project (Post -
Florence Renourishment Project — Phase I) completed under the Bogue Banks Master Beach
Nourishment Plan. Pursuant to the National Environmental Policy Act (NEPA), the environmental
effects of implementing the Bogue Banks Master Beach Nourishment Plan have been evaluated in
an Environmental Impact Statement (EIS). The Final EIS (FEIS) was distributed to state and
federal agencies and a Record of Decision issued in 2018.
1E
The following state and federal permits/agreements have been issued for the Bogue Banks Master
Beach Nourishment Plan:
• The NC Division of Coastal Management issued CAMA Major Permit 991-18 dated
September 4, 2018.
• USACE Action ID No. SAW -2009-00293 dated November 8, 2018 (50 -yr permit).
• NMFS issued Biological Opinion SER -2017-18882 dated October 23 2018.
• BOEM issued Lease Authorization Agreement No. OCS-A 0523 dated February 21, 2019.
(3 -Yr Lease Agreement)
• FWS Statewide Programmatic Biological Opinion Conditions for beach placement will be
instituted.
Permit conditions include dredge window restrictions, dredge cut depth restrictions, sediment
compatibility, and endangered species takes. Measures will be taken by the engineer and
contractor to meet each of these requirements. Beach construction and use of heavy equipment on
the beach will be limited to the November 16 — April 30 time period for placement of beach
material. Dredging in the borrow area will not exceed -52 ft NAVD88. Plans and specifications
will indicate a maximum dredge depth of -50 ft NAVD88 plus 2 ft allowable overdredge. The
large borrow area, containing ample material, will keep individual dredge cut depths to a
minimum. The maximum dredge cut for the Post -Florence Renourishment Project - Phase I was
approximately 7-8 ft and that is expected to remain for the Phase II project. In addition,
undisturbed areas will be left to allow for recovery of benthic resources. Weekly sediment
sampling will be performed by a third party laboratory analysis to ensure grain size and color are
beach compatible. Daily onsite visual assessment of sediment compatibility will also be conducted
by the contractor.
The County may require relocation trawling for the entire length of the project regardless of
whether the mandatory trawling triggers have been met (i.e. water temperature, lethal take).
Endangered species monitoring will be implemented on both the dredge and the trawler, when
working, for the entire length of the project. The project specific BO which applies to the 50 -yr
Master Beach Nourishment Plan has the following incidental take statement:

A "self imposed" incidental take statement was included in the specifications for the Post -Florence
Renourishment Project — Phase I so as to allow a proportionate amount of takes for a single project
17
as compared to the overall allowable takes for the 50 -yr Master Beach Nourishment Plan (see
Table 2-2). This procedure will also be implemented during the Post -Florence Renourishment
Project — Phase II.

It should be noted that the non -lethal trawling takes during Phase I exceeded the "self imposed"
project specific and 50 -yr Master Beach Nourishment Plan allowable takes (see Table 2-3).
Consultation with the agencies was initiated immediately upon the first non -lethal take of a Green
sea turtle and trawling was allowed to continue successfully throughout the remainder of the
proj ect.

Early consultation with BOEM and USACE have confirmed the County will continue with the
project specific BO and incidental take statement. The engineer and contractor will coordinate
monitoring and reporting protocols and points of contact for the Phase II project during the pre -
construction meeting.
3.0 MASTER BEACH NOURISHMENT PLAN STATUS
The Post -Florence Renourishment Project — Phase I was the first project completed under the
Bogue Banks Master Beach Nourishment Plan. A continuation of this project is being planned for
the 2019/2020 and 2020/2021 construction windows. Figure 3-1 presents an overview of the
volumes and extents of the initial project (Post -Florence Phase I) and planned Phase II project.

3.1 Summary of Previous Projects
Post -Florence Renourishment Proiect Phase Iring 2019 Construction)
A 956,000-cy project was designed with the intention to replace the incipient dune and berm lost
during Hurricane Florence along 5.2 miles of beach encompassing three reaches of shoreline in
Emerald Isle and Indian Beach/Salter Path. Emerald Isle East (Reach 1) was planned to receive
615,000 cy of material over 16,400 ft (average of 38 cy/ft) and Indian Beach/Salter Path (Reaches
2 & 3) was planned to receive 182,000 cy of material over 6,100 ft (average of 31 cy/ft) in Reach
2 and 159,000 cy of material over 5,075 ft (average of 32 cy/ft) in Reach 3. The project template
consisted of a dune of variable width at +12 ft NAVD88 with a 1:5 slope down to a berm of
variable width at +6 ft NAVD88 and then a flatter slope of 1:20 out to the existing ground,
landward of the prominent offshore bar. The final project included slightly more material than the
original plan due to changes in the beach during construction as well as the placement of additional
material at the historical hotspot in Reach 1. Emerald Isle East (Reach 1) received a total of
624,945 cy of material over 16,450 ft of beach for an average of 38.0 cy/ft. Indian Beach/Salter
Path (Reaches 2 & 3) received approximately 192,439 cy of material over 6,050 ft of beach in
Reach 2 for an average of 31.8 cy/ft and 158,263 cy of material over 5,100 ft of beach in Reach 3
for an average of 31.0 cy/ft. Table 3-1 and Figure 3-2 summarize the placement locations and
volumes for the Post -Florence Renourishment Project - Phase 1.

Figure 3-2: Post -Florence Renourishment Project — Phase I Volumes
3.2 Master Plan Volumes and Renourishment Intervals
Based on analytical analysis of background erosion rates and historical storm damage, the Bogue
Banks Master Beach Nourishment Plan has allotted 22.6 Mcy of material to mitigate background
erosion and 27.2 Mcy to mitigate storm damage. An additional 1.8 Mcy has been allotted to
account for sea level change. Table 3-2 presents a summary of the volume needs for the Bogue
Banks Master Beach Nourishment Plan over a 50 -year timeframe.

The Post -Florence Renourishment Project — Phase I had a final volume placement of
approximately 975,647 cy of material of which 945,445 cy can be allocated to the storm damage
mitigation allowance and 30,202 cy allocated to background erosion. Current plans call for
4,221,900 cy of material to be placed in the Post -Florence Renourishment Project - Phase II.
Approximately 2,525,355 cy can be attributed to storm damage mitigation and 1,696,545 cy to
background erosion (please recall that a project was being planned prior to Hurricane Florence to
21
mitigate background erosion). Table 3-3 presents the current volume status of the 50 -Year Bogue
Banks Master Beach Nourishment Plan.

Since the first (Post -Florence Phase I) and second (Post -Florence Phase II) projects under the
Bogue Banks Master Beach Nourishment Plan are considered a combination of background
erosion and storm mitigation projects, expected to be completed by spring 2021, the projected 3 -
year renourishment intervals established for background erosion in the Bogue Banks Master Beach
Nourishment Plan (see Table 3-4) would likely not be applicable until 2024-2025 (volume
expected during 2019 and partial volume during 2022 are being accounted for in the Post -Florence
project), barring any storm damage events between now and then.
