8. PROJECT SUNLNIARY:
The Town of Nags Head proposes to dredge up to 4.6 million cubic yards of sand from 3
borrow areas located 2-3 miles offshore and place the material on approximately 10 miles of
oceanfront beaches from Blackmon Street (near mile marker 11) to south of McCall Court
(near mile marker 21).
Project Settinp,
The Town of Nags Head is located at the eastern end of US Route 64/264 in Dare County on
North Carolina's Outer Banks. The town is bordered by the Atlantic Ocean to the east, the
Roanoke Sound to the west, the Town of Kill Devil Hills to the north, and the Cape Hatteras
National Seashore to the south and west. The proposed beach nourishment will occur on the
town's oceanfront beaches located east of South Virginia Dare Trail (NC 12) and Old Oregon
Inlet Road.
The Town of Nags Head's oceanfront lots contain:
• 575 single family residences;
• 115 motels, hotels, cottage courts, and condominiums;
• 43 public beach access sites;
• 3 fishing piers; the Nags Head Fishing Pier, Jennette's Pier which is currently under
construction, and the Outer Banks Fishing Pier Pier, and
• 5 ocean outfalls located near mile markers 10.4, 11.8, 12.2, 12.7, and 21.4.
These ocean front structures are protected by dunes ranging from fairly large dunes in the
northern portion of the town vegetated with beach grass (Ammophila breviligulata), sea oats
(Uniola paniculata), sat meadow grass (Spartina patens) and other indigenous weeds and
grasses, to areas with little or no dune in the southern portion of the town.
The town's beaches are generally flat and vary in width depending on the time of year and
recent storm activity. In general, the beaches are wider in the northern portion of the town and
narrower and flatter in the southern portion of the town. These conditions correspond to the
Division of Coastal Management's published erosion rates of 2 feet per year for most of the
town, with erosion rates increasing up to 6.5 feet per year in the southern portion of the town.
The chronic erosion, previous hurricanes, and recent northeasters has resulted in numerous
structures being located seaward of the crest of the frontal dune and the first line of stable
natural vegetation (FLSNV). These include 66 structures currently protected with sandbags.
Adjacent properties located immediately to the north of the proposed project area contain
single-family ocean front residences. Approximately 5 miles of the undeveloped Cape Hatteras
National Seashore is located south of the town's southern property boundary.
No Coastal Wetlands or U.S. Army Corps of Engineers Section 404 wetlands were observed
within the project area.
The material that will be pumped onto the beaches will be dredged from three separate borrow

areas located 2-3 miles offshore. The three borrow areas are located within a 10 square mile
area identified as S 1 by the U.S. Army Corps Engineers' report titled "Final Feasibility Report
and Environmental Impact Statement on Hurricane Protection and Beach Erosion Control,"
(September 2000) as containing up to 100 million cubic yards (CY) of potentially beach-quality
sand. The three areas that the applicant proposes to use as sources for the sand that will be
pumped onto the beaches are situated in areas with depths of 40-55 feet. Area 1 is
approximately 445 acres in size, while Area 2 encompasses approximately 257 acres, and Area
3 contains approximately 360 acres.
Proiect Description
The Town of Nags Head proposes to conduct dredging efforts 24 hours a day, 7 days a week,
from April 1 through September 30 to nourish approximately 10 miles of the town's beaches.
The town proposes to remove 4.6 million CY of material from 3 borrow areas located 2-3
miles offshore and place the material onto oceanfront beaches from Blackmon Street (near mile
marker 11) to south of McCall Court (near mile marker 21).
The applicant proposes to utilize either a self-contained hopper dredges or other dredging
equipment to remove material from the borrow areas and discharge it onto the existing beach
via a submerged pipeline installed perpendicular to the beach. A discharge pipe up to 36
inches in diameter will be connected perpendicularly to the submerged pipeline (i.e., parallel to
the beach) and installed on the dry sandy beach. The discharge pipe will extend for a distance
of approximately one mile north and one mile south of the submerged pipeline's location. The
discharge pipe will deposit the dredge slurry onto the beach between the seaward toe of the
dune and the mean low water line and be allowed to run onto the beach and into the ocean.
Bulldozers and front end loaders will construct temporary dikes to control the dredge slurry
and evenly distribute the deposited material across the beach to ensure a natural beach profile
is obtained. Once the two-mile length of the discharge pipe has been utilized, the submerged
pipeline line will be re-located approximately two miles further down the beach, the discharge
line will be re-connected to the submerged pipeline at its new location, and the dredge slurry
will be deposited on the next section of the beach. This process will be repeated at least five
times during the nourishment process.
According to the applicant daily operations will directly impact -500 -1,000 feet of shoreline
as work progresses in either direction from the submerged pipeline and any given -500-foot
section of beach is expected to be closed for only about 2-3 days. While areas of active filling
will be closed to protect the public, completed sections will be re-opened as soon as possible to
public use.
Although 4.6 million CY of material will be deposited onto the town's beaches, the material
will not be evenly distributed. The Town of Nags Head proposes to distribute varying
quantities of material along four separate areas designated at "reaches 1, 2, 3, and 4." Reach 1
extends from near Blackmon Street (near mile marker 11) to near Governor Street (near mile
marker 16.5). These 5.7 miles will have approximately 1.74 million CY of material pumped
onto the beach. Reach 2 extends from Governor Street to James Street (near mile marker 19)
and will have 1.3 million CY of material pumped onto this 2.5 miles of beach. The third reach
extends from near James Street to Tern Street (near mile marker 20.5), a distance of 1.7 miles.
Field Investigation Report
Town of Nags Head Beach Nourishment - Dare County
Page 5
This reach will have approximately 1.44 million CY of material placed on the beach. The
fourth and final reach extends .3 miles from near Tern Street to south of McCall Court (near
mile marker 21). This last area will have 120,000 CY of material pumped onto the beach.
[Note: The proposed fill volumes are estimates and may vary by +/- 15%, but the total volume
will not exceed 4.6 million CY].
Fill will reportedly not be placed higher than +6 feet NAVD on reaches 1, 2, and 4. Certain
sections of reach 3 in South Nags Head will not only have material placed on the beach but a
low dune with a height of +12 NAVD will also be constructed.
The placement of the 4.6 million CY of material will fill 250-720 feet of the Atlantic Ocean
below mean low water, 50-250 feet of beach above mean low water, and will advance the
shoreline approximately 50-125 feet.
Detailed data describing the compatibility of the sand located within the three proposed borrow
areas with the existing beach material is presented in the attached narrative.
9. ANTICIPATED IMPACTS
It is anticipated that the proposed development will cause the following impacts:
• Dredging between the months of April and September will increase the probability of
detrimentally affecting threatened or endangered sea turtles.
• The 4.6 million CY of fill will cover and block the five ocean outfalls located within the Town
of Nags Head.
• The proposed beach nourishment efforts will potentially cover sandbags protecting 66
structures located throughout the town.
• The dredging operations will significantly increase the turbidity of the waters in the Atlantic
Ocean near the borrow areas and along the 10 miles of shoreline where the dredge slurry will
be pumped.
• The dredging will disturb approximately 592 acres of sandy bottom habitat located in the
Atlantic Ocean's Public Trust Area and Estuarine Water areas of environmental concern
(AECs).
• Placing the 4.6 million CY of dredge material on the beaches will fill 176 acres of High Hazard
Flood AEC and 415 acres of Public Trust Area and Estuarine Water AECs.
• The round-the-clock dredging activities will disrupt large numbers of ocean-side property
owners and renters during the peak tourist season. Rolling 500-1,000 foot sections of the beach
will be closed for 2-3 days while the beach nourishment activities take place.
• Fill will be placed up to and around structures located seaward of the crest of the frontal dune
and the first line of stable natural vegetation.

NAGS HEAD EMERGENCY BEACH NOURISHMENT
DARE COUNTY, NORTH CAROLINA
NARRATIVE DESCRIPTION OF PROJECT
INTRODUCTION

The Town of Nags Head encompasses -11 miles of ocean shoreline on Bodie Island (NC)
(Figure 1), a barrier island at the northern end of North Carolina's Outer Banks. The
proposed project totals -10 miles of shoreline beginning -1 mile from the town's northern
limit and extending south to the town line adjacent to the Cape Hatteras National Seashore.
The Town of Nags Head faces east to northeast and is bordered by the Town of
Kill Devil Hills to the north and Cape Hatteras National Seashore to the south. The town
is surrounded by Roanoke Sound to the west and Atlantic Ocean on the east. Oregon
Inlet, the closest inlet to Nags Head, is located -5.2 miles south of the town line. The
Town of Nags Head is becoming one of the most densely developed towns along the
Outer Banks due to its accessibility and the demand for coastal property. Proceeding
south from Nags Head, the next nearest beach development is Rodanthe, about 15 miles
away.
Dare County encompasses -89 miles of ocean shoreline from the Town of Duck to Hatteras
Inlet. The northern 30 miles (on Bodie Island) includes the towns of Duck, Southern
Shores, Kitty Hawk, Kill Devil Hills and Nags Head (from north to south). There is a 5-mile
undeveloped portion of Cape Hatteras National Seashore at the southern end of Bodie
Island. The southern -53 miles on Hatteras Island encompass Cape Hatteras National
Seashore and the communities of Rodanthe, Salvo, Avon, Buxton, Frisco, and Hatteras.
Approximately 16 miles are developed and 38 miles are undeveloped along the
oceanfront. In total, 50 percent of Dare County's ocean shoreline is developed, and 50
percent is undeveloped and held in permanent trust by the Cape Hatteras National
Seashore.
Portions of the Dare County barrier island shoreline have been breached in recent times,
particularly near Cape Hatteras. However, there have been no breaches of Bodie Island
in the past century. Most of the island is well over one mile wide and contains
Nags Head Emergency Beach Nourishment Page 1 of 34
Major CAMA Permit Application - Narrative November 5, 2009
dunes reaching elevations well over 25 ft above sea level. Jockey's Ridge in Kill
Devil Hills and the dunes around Kitty Hawk (home of the Wright Brothers Memorial)
exceed 80 ft in elevation.
Nags Head, Kill Devil Hills, and Kitty Hawk support a thriving commercial center and road
system which support more remote areas of the Outer Banks. Nags Head is linked to the
mainland via NC Highway 64, the major artery providing access from inland cities to Cape
Hatteras National Seashore and the resort communities on Bodie and Hatteras Islands.
An estimated 5 million visitors travel to Outer Banks beaches each year, and nearly all
must use roads in Nags Head to get to their final destination.
Nags Head maintains at least 39 beach access locations with parking for the public with
no residency restrictions. There are two public fishing piers remaining along Nags Head.
Both have been shortened over the years due to erosion and repeated damage by storms.
PROJECT DESCRIPTION
The proposed project (Figure 2) consists of excavating by hydraulic dredge up to 4.6 million
cubic yards of beach-quality sediment from ocean borrow area(s) situated -2-3 miles offshore
of the project area. Sediment would be pumped onto the beach between the toe of
the existing dune and the low water line and shaped by bulldozers into a profile that
closely matches the contours and elevations of the natural beach. Approximately 50 percent
of the fill would be deposited by run-out from the discharge point between
mean low water and the outer bar (-500 ft offshore). Typical fill sections would add -50-130
(±15%) cubic yards per linear foot (cy/ft) of beach and advance the shoreline 50 to 125 ft.
The work would be performed continuously, covering all or portions of each of four
designated reaches according to the following plan (subject to local funding availability).
• Reach 1- Stations 491+00 to 790+00 - 5.7 miles - up to 1.74 million cubic yards*
• Reach 2 - Stations 790+00 to 920+00 - 2.5 miles - up to 1.3 million cubic yards*
• Reach 3 - Stations 920+00 to 1010+00 -1.7 miles - up to 1.44 million cubic yards*
• Reach 4 - Stations 1010+00 to 1025+00 - 0.3 miles - up to 120,000 cy*
('Volumes per reach may be adjusted by f15 percent according to conditions at the time of construction.
Maximum overall volume will not exceed 4.6 million cubic yards.)
Nags Head Emergency Beach Nourishment Page 2 of 34
Major CAMA Permit Application - Narrative November 5, 2009
The proposed borrow areas are portions of offshore area S1, the boundary of which is
designated by the USACE (2000) in the federal Dare County project. Several sub areas
within S1 have been sampled and tested for sediment compatibility (detailed results in
later section of the Final EIS that precedes this application). Sediments have been confirmed
over a 2-3 square-mile area within area S1 (-10 square miles) to a section thickness averaging
-8 ft. This yields potentially >13 million cubic yards of beach-quality sediment with overfill ratios
(RA's, CERC 1984) averaging under 1.5. Water depths in borrow areas are -40-55 ft, well
beyond the estimated depth of closure for littoral profiles in this setting. The anticipated
optimal equipment for excavations will be ocean-certified, self-contained hopper dredges.
Such equipment typically excavates shallow trenches (-2-3 ft of section) in each pass
(leaving narrow undisturbed areas at the margin of each cut), then travels to a buoyed
pipeline anchored close to shore. Discharge to the beach is via submerged pipeline
across the surf zone, then by way of shore-based pipe positioned along the dry beach.
Only a small portion of borrow area S1 will be required to provide up to 4.6 million cubic
yards of beach quality material.
The applicant is coordinating the specific area for use in the proposed project with the US
Army Corps of Engineers with the following understanding:
• The final borrow area required for the emergency nourishment project will be limited to
the equivalent of a 0.9-square-mile (-575 acres) area.
• The borrow area used will be contiguous rather than a series of small impact areas.
• Once used, the borrow area will no longer be available for use, consistent with the
federal Dare County project.
• The borrow area will be delineated so as to avoid ongoing biological monitoring
stations established by the USACE in connection with the Dare County project.

SUMMARY OF NEED
Nags Head is the most easily accessible beach in Dare County, representing --13 percent
of the county shoreline and <2 percent of the county land area. Residential and business
properties in Nags Head account for -7 percent of the county tax base but receive a much
lower percentage of county services and investments. Chronic erosion, occurring at
moderate to high rates compared to many shorelines, has accelerated recently as a result
of seven landfall hurricanes in quick succession since 1995. Loss of beach area and a
general sand deficit have left nearly all of the oceanfront vulnerable to damage during
even minor storms. The most recent hurricane (Isabel 2003) caused damage in the
county between $20 and $25 million. Nags Head experienced significant damages where
the beach is narrowest. Little or no property damage occurred along sections of Dare
County (such as the northern end of Hatteras Island adjacent to Oregon Inlet) which had
a much wider beach as a result of nourishment.
Erosion poses an immediate threat to property, infrastructure, and the county tax base.
Loss of oceanfront properties to erosion would result in tax increases for Nags Head
residents.
Tourism, the county's primary industry, will decline if the beach continues to erode. Presently,
there is less recreational beach area for the public than ten years ago. Property
owners have increased the frequency of beach scraping to rebuild foredunes and protect
imminently threatened homes. A decline in beach habitats for nesting sea turtles and other
organisms have been associated with erosion and dune scraping.
A citizens' Beach Nourishment Committee (meeting frequently since 2005) determined that
the only viable alternative is to rebuild the beach via nourishment. Nourishment over a
range of periods results in lower costs compared to the "no-action" alternative or "property
abandonment and retreat" alternative.
The proposed emergency nourishment project is estimated to require up to 4.6 million
cubic yards to provide a minimal protective beach and restore sand losses during the
period of delay while the county waits for a federally sponsored nourishment project by the
US Army Corps of Engineers (USACE 2000). This level of effort would add up to 60-160 cubic
Nags Head Emergency Beach Nourishment Page 4 of 34
Major CAMA Permit Application - Narrative November 5, 2009
yards per foot (cy/ft) along -10 miles of beach encompassing 90 percent of Nags Head
and would widen the recreational beach 50-125 ft. The project would restore eroded
areas to a condition that would be able to sustain chronic erosion and the short-term
impact of storms for at least 6-9 years (the period of delay caused by lack of funding for
the federal project). Project longevity is expected to be at least 10 years for the northern half of
the project based on the planned quantities of nourishment and the lower erosion rates in those
areas. Project longevity is expected to be shorter along the southern 2 miles of the project area
because of higher erosion rates in that area.
Viable beach-quality sand with composite overfill ratios around 1-1.50 exists in strategic
offshore areas close to the shoreline. Preliminary estimates indicate that these deposits
can be excavated and placed on the beach via hydraulic dredge. Other potential borrow sources
(including shoals in Oregon Inlet) are considered less cost effective because of their distance to
the project area and their finer quality material. Inlet sand surveys and sediment compatibility
analyses indicate that it would take 5-10 times more material from the inlet to yield the same
nourishment performance as offshore sand from borrow area S1 (USACE 2000, CSE 2005-
August).
The proposed project (in total) will require -3 - 5 months to construct if using at least two
dredges. The applicant plans for all dredging to be performed under one mobilization. The
applicant desires to complete the project at the earliest time and in the shortest time practicable.
The earliest period of construction is now estimated to be April through September 2010.
Construction activities will directly impact a particular property for only a few days as
nourishment proceeds section by section at an average rate of about 300 feet per day. The
project will be monitored carefully after construction to quantify its longevity and document
environmental change. As the first large nourishment along the northern Outer Banks, it will
necessarily serve as a prototype for future beach maintenance efforts.
METHODS OF CONSTRUCTION
The proposed fill will be pumped to the beach placed ocean going trailer suction hopper and/or
ocean certified hydraulic dredge(s). The fill will be placed between the seaward crest of the
existing dry beach and seaward to the mean low water elevation (Figures 3 -17). Only the
Nags Head Emergency Beach Nourishment Page 5 of 34
Major CAMA Permit Application - Narrative November 5, 2009
profile above high water is controllable in nourishment construction. The action of waves and
tides will adjust intertidal and underwater portions of the profile. The fill will be placed no higher
than +6 ft NAVD (the natural elevation of the berm) along Reaches 1, 2, and 4 (Figures 18 &
19). Portions of South Nags Head will include a low dune of varying width at elevation of +12 ft
NAVD along areas that lack dune protection. The total dune width will vary depending on
location and will have a maximum crest elevation of +12 ft NAVD. Fill will be placed up to the
foundations of existing structures. No fill placement will be permitted under structures.
Work will progress in sections within the borrow area(s) and along the beach. The borrow area
will be left to adjust naturally and to recolonize while other areas are being excavated. Fill
placement along the beach will typically involve completion of 300-700 linear feet of beach per
day. Construction activities will involve movement of heavy equipment and pipe along -1 mile
reaches over a period of 2-3 weeks. 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 and opened for use by the public. Other than equipment
staging areas, individual lots along the oceanfront will experience disruption due to construction
for one month or less, in general. Fill volumes will be confirmed by surveys and beach sections
left to adjust naturally for several months following completion of the fill. Sand fencing and dune
plantings will be installed along the landward most portions of the completed beach.
Land-based equipment will be brought to the site over public roads and will enter the beach at
town approved existing permanent beach access areas identified on the construction drawings.
Typical land based equipment may include, but is not limited to front end loaders, backhoes,
bulldozers, excavators, tractors, discharge pipe (typically 36 inches in diameter), welding
machines, a field office skid and portable toilets. These access areas will be closed off to the
public for safety reasons until project completion. Other than at equipment staging areas, beach
residents along the project area will experience disruption due to construction for several days,
or less.
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. Existing dunes and vegetation on the beach will be avoided and preserved.
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.
Nags Head Emergency Beach Nourishment Page 6 of 34
Major CAMA Permit Application - Narrative November 5, 2009
The contractor will choose exact locations for "sub line" landings. These are submerged
discharge pipes run perpendicular to shore and connect the dredge to the land based discharge
pipe. It is expected that a minimum of 5 "sub line" landings will be required to complete the
project.
A hopper dredging pumping sequence includes connection of the hopper dredge at the sub-line
connection point, flushing of the pipeline with clear water, and pumping of the sand water slurry
to the beach until the hopper is empty. For a hydraulic dredge, pumping is more or less
continuous for a given segment of beach until the maximum pumping distances are reached on
the beach. Once the maximum pumping distance is reached in one direction, the discharge
pipe will be disassembled and work will progress in opposite direction. When the maximum
pumping distances are reached in both directions, the operation is relocated to the next sub-line
landing and the process is repeated until the project is completed. Construction of each
segment of beach will begin at the sub-line landing and progress approximately 1 mile North
and South at a rate of 300 to 700 linear feet of beach per day. Approximately 1,000 to 2,000
feet of beach will be closed to the public at any given time to allow for construction activities to
operate in a safe manner. Construction activities will continue 24 hours a day, 7 days a week
with no stoppages for holidays. Short periods of inactivity will occur for weather related delays,
equipment repairs and refueling.
A typical hopper dredge will spend approximately 1 hour removing material from the borrow site.
After the hopper is full, the dredge will sail to the appropriate "sub line" and connect. The
discharge line will be flushed with seawater to ensure no blockages are in the line. Fill material,
in slurry form (50% material, 50% water), discharge will immediately follow line flushing.
Earthen dikes will be constructed by land based equipment to control discharge. Beach
construction will begin at the landing and progress approximately 1 mile either North or South at
a rate of 300 - 700 ft per day. Once distance limit is reached then the discharge pipe will be
disassembled and work will progress in opposite direction. This process will be repeated until
project completion. Approximately 1,000 to 2,000 feet of beach will be closed off to the public at
any given time to allow for construction activities to operate in a safe manner. A right of way of
10-20 ft is expected to be provided landward of the construction area to allow citizens safe
passage along the beach. Beach nourishment activities are expected occur 24 hours a day, 7
days a week until project completion.

Major CAMA Permit Application - Narrative November 5, 2009
Construction Schedule
The proposed project involves dredging and placement of up to 4.6 million cy of beach quality
sand. The average production per day varies widely according to sailing distances from the
borrow area to the beach and specifications for the project. It is anticipated that the proposed
construction will be accomplished in approximately 5 months using multiple dredge plants
including multiple hopper and/or a hydraulic dredge. Based on project experience, a single
hopper dredge can excavate and place on the order of 10,000 - 20,000 cy of sand in a 24-hour
period. A hydraulic dredge can dredge and pump 30,000 to 50,000 cubic yards per day
depending on factors such as depth of cut, pumping distance and texture of the dredged
material. The applicant requests a permit for construction between April and September. This
schedule is predicated on safety and logistic considerations based on experience with prior
projects (850,000 cy in summer 2008 Isle of Palms, SC), including recent work in Sandbridge,
Virginia (-3.5 million cy in summer 2002 and Summer 2007 via hopper dredge).
A major factor that must be considered for work along the shoreline of the Outer Banks is
weather. Wind and wave conditions characteristic of winter weather (November to March)
would present a hazard to both hopper and cutterhead dredging operations. Frequent
northeasters will require that dredging equipment seek refuge at Chesapeake Bay (Tidewater
Va) safe-harbor locations when storms are predicted to impact the proposed project area. The
downtime associated with shutdown and redeployment of the dredges represents a significant
economic impact on the proposed project. Permitting the dredges to work over warm weather
months would relieve this risk to man and machine and provide conditions where the work could
be completed in a much smaller time period, thus reducing the duration of environmental
impacts.
Detailed information on dredging production and efficiencies for North Carolina projects,
including maintenance dredging in Oregon Inlet, are given in Appendix H of the FEIS.

Cumulative Impacts
The Council on Environmental Quality defines cumulative impacts as:
the impact on the environment which results from the incremental
impact of the action when added to other past, present, and
reasonably foreseeable future actions regardless of what agency
(Federal or non-Federal) or person undertakes such other actions.
Cumulative impacts can result from individually minor, but
collectively significant actions taking place over a period of time.
(NEPA 40 CFR 1508.7)
After Hurricane Isabel (2003), FEMA (ref: project worksheet PW 299 dated 28 September
2003) authorized an emergency dune restoration project which added 6-10 cy/ft above
+6 ft NAVD on the beach along -9 miles of the Nags Head shoreline. The project utilized
an inland borrow source (-365,000 cy) for dune construction (CSE 2005-June). There
were no significant environmental impacts associated with this project.
No previous nourishment events have taken place along Nags Head's oceanfront. The
proposed project is a single nourishment event which will encompass -r10 miles of shoreline.
The time between the FEMA emergency dune restoration project and the proposed
nourishment project (-4-5 years), combined with the fact that the nourishment project will
impact the recreational beach and underwater profile (not the dune), suggests there will
be no cumulative impacts of these two projects.
Cumulative impacts are expected to occur if the USACE's Dare County project is constructed
and renourishment is performed according to the federal schedule at -3-year
intervals. The Town of Nags Head does not anticipate renourishing the beach under a
locally sponsored project for at least ten years, given budget constraints and other criteria.
Cumulative impacts of the federal project are addressed in more detail in USACE (2000).
The schedule for implementation of the initial federal project and its planned renourishment
intervals is not available at this time.

MITIGATION
The Town of nags Head is committed to the protection of federally listed species. To minimize
the potential impacts to such species in the project area, the following commitments to reduce
impacts will be implemented.
1) Follow NMFS and USACE hopper dredging protocol (FEIS Appendix H) to
minimize the impacts of hopper dredging. Currently, there are no known
seasonal restrictions for dredging along the northern Outer Banks. Furthermore,
turtle deflector dragheads will be properly installed, maintained, and utilized.
2) A turtle relocation trawling plan will be implemented. The plan calls for two turtle
trawlers to mobilize when water temperatures reach 55° F. Trawling will
commence when water temperatures reach 57° F. The applicant will
electronically monitor the locations of trawlers and hopper dredges so that
trawling is implemented to maximum effectiveness.
3) Full-time observer(s) will be present on the hopper dredge(s) to document visible
sea turtle activity, monitor any takes of sea turtles, and watch for and alert the
dredge operator of whales or manatees in the area. Observers will be on the
bridge from the beginning of hopper dredge use through completion of project.
4) Measures to avoid impacts to manatees will be followed as described in
"Guidelines for Avoiding Impacts to the West Indian Manatee in North Carolina
Waters" by the USFWS.
5) A standardized turtle nest monitoring and relocation plan is in place for the Town
of Nags Head (FEIS Appendix H - Attachment 13, Section C). This program
includes daily patrols of active beach disposal areas at sunrise, relocation of any
nests identified in areas to be impacted by fill placement, escarpment formations,
and monitoring of hatchling success of the relocated nests.
6) Follow NMFS marine mammal stranding report procedure outlined in FEIS
Appendix H (Attachment 13, Section B).
Nags Head Emergency Beach Nourishment Page 10 of
34
Major CAMA Permit Application - Narrative November 5, 2009
7) Lights on bulldozers will be shielded so as not to deter sea turtles from the
construction area.
8) A standardized turtle nest monitoring and relocation plan is in place for the Town
of Nags Head (FEIS Appendix H-Attachment 13, Section C). This program
includes daily patrols of active beach disposal areas at sunrise, relocation of any
nests identified in areas to be impacted by fill placement, escarpment formations,
and monitoring of hatchling success of relocated nests.
9) Visual surveys for escarpments along the project area will be made immediately
after completion of the beach nourishment project and prior to March 01 for three
subsequent years. Escarpments that interfere with sea turtle nesting or that
exceed 18 inches in height for a distance of 100 ft will be leveled to the natural
beach contour by March 01.
10) In addition, sand of similar grain size to the existing beach will be used to reduce
any changes in physical characteristics of the beach that may affect turtle nest
survival. Sand quality is expected to meet or exceed the NC Coastal Resources
Commission (CRC) technical standards for beach fill projects (NC Rule: 15A
NCAC 07H .0312)
11) Beach compaction will be monitored and tilling will be conducted in areas where
the post-disposal beach is harder than 500 CPUs to reduce the likelihood of
impacting sea turtle nesting and hatchling activities.
12) Piping plover surveys will be conducted in accordance with the NPS monitoring
program for CAHA. Monitoring focuses on identifying nesting habitat, locating
breeding plovers and nests, protecting territories and nests, and determining nest
and brood success. Monitoring methods are outlined in FEIS Appendix H -
Attachment 14, Section D.
Nags Head Emergency Beach Nourishment Page 11 of

Major CAMA Permit Application - Narrative November 5, 2009
13) Seabeach amaranth populations will be surveyed in the proposed project area by
the applicant to monitor recolonization of the plants after project completion.
Preproject surveys commenced in the summer of 2007 and will continue annually
for two years following project completion. Data collection will help predict
ultimate impacts of beach nourishment on seabeach amaranth at Nags Head and
will be made available to the USACE's seabeach amaranth monitoring program.
Appropriate conservation measures will be taken to protect the seabeach
amaranth. The project will occur on the areas suffering from erosion and should
ultimately expand potential habitat for the seabeach amaranth. Seabeach
amaranth plants found in the construction path will either be delineated and
protection measures provided or they will be relocated to a suitable habitat away
from potential harm.
14) The applicant will perform periodic surveys of the project area so as to estimate
the volumetric erosion and provide updated design criteria for application in the
federal project.
SEDIMENT COMPATIBILITY
Nags Head Native Beach and Offshore Borrow Area Sediment Characteristics
Sediment characteristics were evaluated for the recipient beach and potential offshore borrow
sites in connection with the proposed nourishment project at Nags Head, NC (USACE Action ID
# SAW 2006-40282-128). This section supplies updated characterization of the beach and
borrow areas in accordance with NC Coastal Resources Commission (CRC) technical
standards for beach fill projects (NC Rule: 15A NCAC 07H .0312) which were changed after
initial submission of project documentation by CSE. Beach and borrow area sediment
descriptions were previously reported in the EIS and CSE 2005, however the updated CRC
criteria required additional samples and analysis which were not previously included. It also
includes compatibility analysis of borings which were obtained after submission of the draft EIS
which were not included in the initial analysis. The report presents results of sediment analysis
conducted on 182 samples from 14 transects on the recipient beach (a total of 110 samples
were characterized in the EIS) and 226 samples from 100 offshore borings.

• Previous sediment compatibility analyses are given in the EIS in Section 4.16
and also Appendix D. Grain size distributions for offshore borings 01 - 102 are
supplied in Attachment 1.
Recipient Beach
Characterization of the recipient beach required 14 shore perpendicular transects at 5,000 ft
spacing along the length of the intended project area (Figure 20). At each transect a total of 16
samples (182 total) were obtained including samples from the dune, dune toe, mid berm, berm
crest, mean high water (MHW), mid tide, mean low water (MLW), low-tide terrace (LTT), trough,
bar, outer bar, and at -8, -12, -16, and -20 ft NAVD. Following CRC criteria, the total number of
samples used for characterization of the recipient was 13 samples per transect, with 6 samples
above and below MLW (Figure 21). Samples were collected in two deployments, the first in
May 2005 and the second in November 2008. The second series was collected to comply with
CRC rules which were updated after initial submission of the EIS. These samples included four
samples between the berm crest and MLW, and four samples from -8 to -20 ft NAVD. Samples
collected in November 2008 were analyzed in the same manner as those previously collected
following standard procedures. Results of the individual sample analysis of the recipient beach
are listed in Table 1. Grain size distributions for each sample are given in Attachment 2. Mean
grain size for all samples ranged from 0.136 mm to 1.641 mm, and averaged 0.306 mm. No
samples possessed sediment in the gravel (4.76 mm or greater) size class. The granular
fraction (2.0 to 4.76 mm) ranged from 0.0 to 60.6 %, averaging 3.8 %. Sand-sized sediment
(0.0625 to 2.0 mm) averaged 96.1 % for all samples with the majority being >98%. Fine grained
material (less than 0.0625 mm) ranged from 0.0 to 4.6 % and averaged 0.1%. Shell (calcium
carbonate) content ranged from 0.2 to 15.1 % with an average of 1.8 %.

The updated CRC criteria also require a survey of clasts on the recipient beach which are larger
than 3 inches in diameter. CSE conducted this survey 14 January 2009 over a 50,400 sq ft
area (Figure 22). The area represented a 140 ft wide (cross shore direction) by 360 ft long
section of beach between the dune toe and MLW. Survey lines were parallel to the shoreline at
10 ft spacing. Field personnel walked each line from North to South looking waterward to cover
entire area. The purpose of the survey grid was to allow complete coverage of the survey area
and to eliminate duplicate clast counts. The total number of clasts found in the - 50,000 sg ft
section of beach was 117. Figure 22 shows representative photos of clasts found during the
survey.

Borrow Area
CSE collected 100 borings utilizing proprietary coring techniques with 3 inch core barrels within
the boundaries of an offshore area (S1) defined by USACE (Figure 23) for possible use as a
borrow area for the federal Dare County project (USACE 2000). It was chosen for investigation
because of previous studies and recommendations by the USACE. Area S1 designated by the
USACE potentially contains over 100 million cy of beach quality sediment (USACE 2000).
Data from borings 1-61 were included in the original compatibility analysis reported in the Draft
EIS in 2006. Borings 62-102 (two sites were not recovered) were obtained after submission of
the draft EIS and were not included in the original compatibility analysis, however grain size
distributions were reported in the EIS Supplement I, Divider 5, Attachment 1. The present
analysis combines all data obtained by CSE and presents the results as described by updated
CRC criteria, which were changed after the initial submission of the EIS.
Based on the 100 borings, CSE previously selected 3 potential sub-areas for proposed borrow
sites (Areas 1-3, EIS section 4.16). The present analysis further refines these areas by omitting
the western portion of Area 1 (Figure 23, grey-shaded region) This was done in order to
achieve the CRC core density criteria of 1 core (or more) per 23 acres. The proposed usable
portion of Area 1 is presently referred to as Area 1 East. Certain statistical values are shown for
the previously delineated Area 1 [designated as Area 1 (All)], and are included for reference
with previous reports. The potential borrow areas identified by CSE are described in Table 3.
Average core recovery depth was between 7.9 and 8.5 ft. Core density was between 11.1 and
22.1 acres per core. The total area of all three borrow areas, when the western portion of Area
1 is discounted, is 1,048 acres. Potential volumes for various dredging depths are shown in
Table 3.
Tidewater Atlantic Research, Inc. of Washington, North Carolina conducted a magnetometer,
sidescan sonar, sub-bottom profile, and fathometer survey of the proposed borrow area in July
2009, Appendix A. The purpose of this survey was to meet CRC's geophysical requirements for
borrow site characterization.

Table 4 reports sediment characteristics for each offshore sample, including the interval within
each boring from which the sample was taken. Attachment 1 provides grain size distributions for
each offshore sample obtained for cores 1-100. Mean grain size for the offshore samples
ranged from 0.194 to 0.782 mm, with an average grain size of 0.410 mm. No gravel (or greater)
sized sediment was present in the offshore samples. Granular sediment ranged from 0.0 to
39.3 % and averaged 4.0 %. Sand sized sediment ranged from 60.7 % to 100 %, averaging
96.0 %. Fines were present between 0.0 and 2.2 %, averaging 0.1 %.

Table 5 shows composite results for each core (65 total) within the proposed borrow areas, as
well as for each borrow area as a whole, for potential dredge depths of 4, 6, and 8 ft. Though
not required by CRC, a calculation of the overfill factor (RA) for each core and borrow site is also
listed in Table 5. The overfill factor (James 1975) is used to estimate the amount of borrow area
volume which will be required to perform as 1 unit of native material. Generally, numbers < 1.5
are desirable, with 1.0 being best suited for nourishment. Each proposed borrow area
composite (to 8 ft dredge depth) overfill ratio was 1.0, meaning the borrow material will perform
well and less material will need to be dredged to accomplish the project goals. Further, the
proposed borrow material very closely matches the native size class characterization, with no
gravel observed, 2-4 % granular-sized sediment, very little fine-grained material (0.1%) and 1-2
% calcium carbonate. Core logs and photographs are provided in Attachment 3.

According to the updated CRC sediment criteria, each borrow area must meet the following
conditions:
• The average percentage by weight of fine grained material shall not exceed the
average percentage by weight of fine-grained sediment of the recipient beach
plus 5 %.
• The average percentage by weight of granular sediment shall not exceed the
average percentage by weight of coarse-sand sediment of the recipient beach
plus 5%.
• The average percentage by weight of gravel shall not exceed the average
percentage by weight of gravel-sized sediment of the recipient beach plus 5%.
• The average percentage by weight of calcium carbonate shall not exceed the
average percentage by weight of calcium carbonate of the recipient beach plus
15%.
• And sediment and shell material (clasts) greater than 3 inches shall be
considered incompatible if when placed, the observed concentration is in excess
of twice the background value of material of the same size along any 50,000 sq ft
section of the beach, observed between MLW and the frontal dune toe.
Under these conditions, and with the reported characterization of the native beach at Nags
Head following CRC criteria, a compatible borrow area will possess no more than 5 % gravel,
8.8 % granular sized sediment, 5.1 % fine material, and 16.8 % calcium carbonate. For each
borrow area and dredge depth, the three proposed borrow areas meet the conditions described
above. The similarity of the sand-size classes between the recipient beach and the potential
borrow area suggests that the sand will look and perform well once placed on the beach. Very
little fine-grained material was encountered in the borings which minimizes the amount of
borrow material needed for nourishment to accomplish the goals and objectives of the plan.
The low amounts of fine-grained material are expected to minimize turbidity when dredging
takes place. Shell content was also very similar to the native beach which will produce a similar
looking beach to the native. CSE counted 117 clasts larger than 3 inches in a 50,400 sq ft
reference section of the recipient beach. According to the criteria, the replenished beach should
Nags Head Emergency Beach Nourishment Page 30 of
34
Major CAMA Permit Application - Narrative November 5, 2009
not contain more than twice this value. In summary, the proposed borrow areas meet the
updated CRC criteria and also meet CSE's sediment criteria, which aim at producing a stable
project which is as economically and environmentally compatible as possible.
FILL PLACEMENT
Permitting of a range of fill volumes generally from 50-130 cubic yards per linear foot
(cy/ft) of beach is recommended. The extent of the construction will depend on bid prices
and the funding available. Reaches for the beach fill are shown in Figure 2. Nourishment
sand will be pumped from the selected borrow area (within the boundaries of S1) via
hopper dredge to areas along Nags Head. The emergency project is based on the need
to replace sand lost in recent years until such time as the federal Dare County project can
be accomplished. The Town of Nags Head proposes to place up to 4.6 million cubic
yards along the beach, which equals -6-9 years or more of projected sand losses according to
the federal project formulation under the Dare County EIS (USACE 2000).
The proposed berm fill will tie into the +7 ft NGVD 29 elevation. Elevations above the +7 ft
contour are not expected to receive any fill, except in some areas in Reach 3 for dune
restoration. Dune restoration areas will tie into the +13 ft NGVD 29 elevation. All fill will be
seaward of the first line of stable natural vegetation.
Fill material will be pushed up to residences that are currently threatened by erosion. It will be
either the Town or home owner's responsibility to place fill under the residence.
Dare County Department of Environmental Health state that exposed septic systems will be
evaluated prior to construction. Damaged septic systems will have to be removed prior to
construction and may be replaced after project completion if the system lies outside the 50 ft
setback (from Normal High Water) requirement. Fill material will be placed over septic systems
deemed undamaged.
Sand bags are expected to be covered by beach fill, unless DCM specifies otherwise. DCM will
be notified of any sand bags found to be a project impedance. The project will proceed
accordingly after consultation with DCM, if necessary.

STORMWATER MANAGEMENT
No upland improvements, pavements, walkways or other impervious surfaces will be
constructed as part of the project. No stormwater management or additional stormwater
measures will be required for this project.
The NCDOT proposes to extend the existing stormwater outfalls a distance beyond the seaward
extent of the proposed beach fill so flow is maintained in the culverts after the project is
completed. The stormwater outfalls will continue to be maintained by NCDOT after.project
completion. NCDOT has been funding significant repair of all the (8) outfalls in Dare County
over the last two, and future fiscal years.
COMPLIANCE WITH DARE COUNTY ZONING AND CAMA LAND USE PLAN
The beach nourishment project is consistent with the approved CAMA Land Use Plans for Dare
County and the Town of Nags Head. Nags Head latest CAMA Land Use Plan is consistent with
their last approved plan.
The project property is within the planning jurisdiction of Nags Head. The town is classified as
"Developed" by the Town's and County's CAMA Land Use Plan.
COMPLIANCE WITH THE NORTH CAROLINA ENVIRONMENTAL POLICY ACT
The Division of Coastal Management (DCM) issued a Record of Decision, Attachment 4, on 17
Feb 2009 for the proposed project. DCM determined that the FEIS for the proposed project
meets the NCEPA requirements and will serve as a decision making tool for the final regulatory
decision.
CONSTRUCTION EASEMENTS
Perpetual beach nourishment easements are in place for virtually the entire ocean front of Nags
Head. The easements will be acquired prior to construction start.

The perpetual easements are for any part of private property that visibly appears to be a part of
the ocean beach strand and is covered with little or no vegetation, is seaward of the last line of
stable vegetation, is within the frontal sand dune, or is seaward of the erosion escarpment. The
easement permits all work necessary to nourish the beach. However, the town cannot damage
permanent improvements in the easement area and must work with property owners to remove
and replace permanent improvements in the easement area that obstruct nourishment.

Abstract
Coastal Science and Engineering, Inc. (CS&E) is working with the Town of Nags
Head, Dare County, North Carolina to identify a source of beach nourishment
quality sand to restore beaches. Three offshore areas east of Bodie Island have been
identified as potential borrow sites. In order to determine the proposed projects
effects on potentially significant submerged cultural resources, CS&E contracted
with Tidewater Atlantic Research, Inc. of Washington, North Carolina to conduct a
magnetometer, sidescan sonar, sub-bottom profiler and fathometer survey of the
proposed borrow sites. Field research for the project was conducted between 2 and
5 July 2009. Analysis of the remote-sensing data generated during the survey
identified two target clusters, each composed of three individual magnetic
anomalies. None of the magnetic anomalies had an associated acoustic signature.
Both target clusters are located in Area 1 and have signature characteristics
suggestive of potentially significant submerged cultural material. Avoidance of
these two target clusters is recommended by the creation of a 400-foot diameter
buffer around each site. Should avoidance of these two target clusters prove
impossible, additional investigation is recommended to identify material generating
these anomalies and assess their importance in terms of National Register of Historic
Places eligibility.
