North Topsail Beach — CAMA Major Permit Modification, No. 79-10

The permittee is requesting approval, through this CAMA major permit modification, to re -align a
portion of the New River Inlet channel (bar) and place the excavated dredge spoil material along
the ocean front shoreline of North Topsail Beach.
The project site is located within New River, and along the northern end of the North Topsail Beach,
adjacent to the Atlantic Ocean and New River Inlet, in North Topsail Beach, Onslow County. To get to
the site from Wilmington take US HWY 17 N to NC Hwy 210, which is located at the Lowe's Home
Improvement on US HWY 17. Turn right onto NC Hwy 210 and continue across the Surf City Swing
Bridge. Take a left at the first street New River Road (NC Hwy 210). Continue on NC Hwy 210 until you
reach the North Topsail Beach. Turn right onto New River Inlet Road and travel to the northern terminus
of the island. The project will originate just south of this area adjacent to 2328 New River Inlet Road. The
project site encompasses approximately 3.63 miles of oceanfront beach starting at 2328 New River Inlet
Road and terminating at 764 New River Inlet Road. The current elevation of the project area ranges from
approximately —10' NAVD to approximately 18' NAVD. The project site is adjacent to commercial and
residential properties also infrastructure for the Town including NC Hwy 210. The project site is bordered
by Onslow Beach to the North, the Atlantic Ocean to the East, and commercial and residential properties
to the south and west. The highground portion of the property is vegetated primarily American Beach
Grass (Ammophila breviligulata) and Sea Oats (Uniolapaniculata).
The Annual erosion rates for the Town ranges from 2'/year to 2.5'/year per the Division of Coastal
Management's 2011 Annual Erosion Rate maps.
The Town of North Topsail Beach Land Use Plan does not have the dry sand beach classified. However;
the upland areas of this project are classified as Developed. The waters of the project site are classified as
SA by the NC Division of Water Resources. The NC Division of Marine Fisheries has NOT designated
this area of New River / Atlantic Ocean as a Primary Nurser, and the waters adjacent to the
proposed project are OPEN to the harvesting of shellfish.
PROJECT DESCRIPTION:
The Town of North Topsail Beach currently has several CAMA Major Development Permits that are
active, including CAMA Major Permit No. 79-10 (Shoreline Stabilization), No. 191-05 (Beach
Bulldozing) and No. 92-14 (Sand bag revetment).
CAMA/Dredge and Fill Permit No. 79-10 was issued to the Town of North Topsail Beach on July 21,
2010, and authorized a Town wide "shoreline stabilization" project which consisted of dredging a portion
of New River Inlet bar channel, as well as an offshore borrow area. Dredge material from these areas was
authorized to be deposited along the entire ocean front shoreline of North Topsail Beach in five (5)
phases. To date, the Town has completed "shoreline stabilization" along the majority of the ocean front
with the exception of Phases 2 and 4.

North Topsail Beach — CAMA Major Permit Modification, No. 79-10
Page Three
Under this permit modification, the Town proposes to re -align a portion of the New River Inlet channel
bar and place the dredge spoil material along the northern section of North Topsail Beach, from 2328
New River Inlet Road to 764 New River Inlet Road, which is within Phase 1 of the original permit
template. The circumstances triggering this request result from natural shoaling (filling) of the previously
permitted channel alignment, in excess of 85% of the actual dredged volume of the initial construction.
Based on information provided by the applicant's consultant, the initial channel dredge volume has
exceeded the COE's fill criteria (for exceeding the EIS threshold of one dredge event per every four (4)
year interval) by approximately 20% (+/- 105% by volume). As a result, the Town seeks approval to re-
cut the bar channel and pivot the channels location approximately 17 degrees to the east, and place
approximately 700,000 cu. yds. of material on the ocean front shoreline.
According to the application package, the proposed "action plan" consists of a 31 shoreline protection
event and inlet management plan beginning as soon as November 2016. As previously stated, the channel
would be repositioned approximately 17 deg. to the east as compared to the original channel footprint that
was dredged in 2012/2013. The depth of the proposed new cut would terminate at the -18' contour
(NAVD), consistent with the previously authorized depth. The width of the modified channel would
remain the same as originally permitted (+/- 500'); however, the length of the project would extend from
3,375 linear feet (as originally permitted) to 3,650 linear feet. According to recent hydrographic survey
data (provided by the applicant), existing depths within the channel bar range from -T to -8' NAVD,
giving a total dredge volume of approximately 700,000 cu. yds. Please refer to sheet BA -1 for a detailed
depiction of the proposed channel re -positioning.
In order to remain consistent with the State's compatibility standards, ten (10) additional vibracore
samples were collected from areas within the re -positioned channel footprint during 2016. According to
the application package, sediment analysis collected during this time frame suggest that material held in
storage with the proposed channel maintenance area(s) meet the criteria for fine-grain, sand, granular and
gravel. Please refer to Appendix F, page 9 for detailed grain size analysis.
Excavated material dredged from the re -positioned channel would be piped to the beach and deposited
along the shoreline from 2328 New River Inlet Road to 764 New River Inlet Road. This section of beach
includes all of Phase 1 and some of Phase 2 of the original project/permit. The disposal area would
encompass a total of approximately 9,670,575 sq. ft. of ocean front shoreline, with approximately
7,075,513 sq. ft. being located below the mean high water line. Based on drawings provided in the
application package (specifically, Sheets PV -2 through PV -8), dredged material would be deposited from
an area just seaward of the "project baseline" to a distance approximately 500' feet east, below the mean
high water line. The landward beach dune created from this project would be locatedjust below the
"project baseline" and would measure approximately 100' in width. Just seaward of the seaward toe of
the existing beach dune, a beach "berm" would be constructed. The berm would originate at
approximately +6' NAVD and would extend offshore approximately 420' (from dune to), terminating at
elevation -7' to -8', NAVD. These depths and contours appear to be consistent within the project area,
with exception to the area front Topsail Reef, where the offshore fill limits would extend beyond -10'
NAVD.
Lastly, the application package includes a draft report summarizing a Cultural Resources remote sensing
survey of the project area, conducted by Tidewater Atlantic Research, Inc. (TAR). The report, dated
August 1, 2016, concludes that N.C. Underwater Archaeology Branch (UAB) files list two known sites in
the vicinity of the survey area: 001/003NWI and 002NWI. Both sites were identified as the remains of
"small nineteenth-century sailing vessels lost in New River inside the bar".

North Topsail Beach — CAMA Major Permit Modification, No. 79-10
Page Four
According to TAR analysis from the remote -sensing operations, a total of nine (9) anomalies in the south
buffer area and a total of 23 anomalies in the northern buffer area, However, the report indicates none of
the 32 anomalies rest within the proposed pivot channel alignment. A final conclusion from the report
suggest that no additional investigation is recommended in conjunction with the proposed project, as there
would likely be no adverse impacts on the anomalies identified throughout TAR's report.
10. ANTICIPATED IMPACTS
The proposed dredging would result in the removal of approximately +/- 42 acres (1,825,000 sq. ft) of
shallow bottom from the inlet area. The fill portion of the project would result in the disturbance of
approximately 59 acres of beach above NHW and would fill approximately 162 acres of shallow bottom
below NHW.

11A 6z'_! Project lVarlra:ive.
The Town of North Topsail Beach (Town) is located on the southeastern coastline of Onslow
County in southeastern North Carolina. The municipality is located on a barrier island, bordered
to the south by the Town of Surf City, to the west by the Atlantic Intracoastal Waterway (AIW W),
to the north by New River Inlet. The United States Marine Corp base Camp Lejeune and Onslow
Beach is located North of New River Inlet. Topsail Island is approximately 22 miles long with the
Town of North Topsail Beach encompassing the northern 11 miles of the barrier island. The
proposed project entails the placement of beach compatible material along approximately 3.63
miles of the Town's oceanfront shoreline and maintenance of the previously relocated channel
within New River Inlet. Material from the channel maintenance will be placed from approximately
2328 New River Inlet Road to 764 New River Inlet Road.
2.1.1. Project .Bv round
The Town completed Phase 1 of its beach and inlet management plan in February 2013. Phase 1
included relocating the main bar channel of New River Inlet to a preferred position and alignment
with deposition of the dredged material along approximately 7,730 feet of the Town's shoreline
south of New River Inlet. The intent of the bar channel relocation was to induce a build-up of
material on the south side of New River Inlet that would eventually result in accretion along the
northern portion of the Town's shoreline. CPE -NC stated in the engineering report associated with
the Final Environmental Impact Statement (EIS) that predictions of the actual time for the
shoreline between stations 1140+00 and 1160+00 (area from between Buildings #5 and #6 of
Topsail Reefs to the south shoulder of New River Inlet) to respond to the new channel cannot be
made with a high degree of certainty; however, significant accretion should occur within 5 years
with full recovery occurring within 15 years following the channel relocation (CPE -NC, 2009).
These projections were based on the implementation of a channel maintenance program that would
maintain the channel in the preferred location.
During the first two years following completion of Phase 1, fill placed along the northern portion
of the project from baseline station 1130+00 north to the inlet experienced high rates of erosion.
Essentially all of the fill material placed in this area eroded with most of the material being
transported by natural processes to the north. A large portion of this naturally transported sand
accreted on the southern shoreline of New River Inlet in the form of a sand spit. The erosion of the
fill material placed seaward of the homes north of Topsail Reef during the Phase 1 project left
these structures in imminent danger comparable to the conditions of the structures prior to the
construction of the Phase 1 project. This prompted the Town of North Topsail Beach to construct
a sand bag revetment to provide temporary erosion control along this section of shoreline.
In March 2015 CPE -NC provided the Town with a contingency report, whichr%
recommendations for modifications to the existing long-term inlet management str N, NC

with the Town's long-term beach and inlet management program. One of the four
recommendations described in the Contingency Plan to improve project performance was the
modification of the channel alignment for the 2nd channel realignment event scheduled for the
2016/2017 environmental dredging window.
In July 2015, the Town authorized CPE -NC to conduct a numerical modeling study using the
Delft3D morphological model to evaluate alternative channel alignments for the proposed 2016-
2017 project. The Delft3D model was used as an engineering tool to evaluate relative differences
in response of a system (beach and inlet) to channel modification. Model simulations of alternate
channel alignments were used to evaluate model -indicated volumetric changes along the adjacent
shorelines, changes in the ocean bar channel (channel orientation, shoal volumes, channel depths,
etc.), volumetric changes on the ebb tide delta, and sediment transport patterns. The model results
were also used to assess relative differences in flow patterns from one option to another,
differences in the significant wave heights that would impact the shoreline, and potential changes
in the volume of water that would pass through various channels within the system.
7.1,1.2 Proposed Action
The Department of the Army permit (Permit No. SAW 2005-00344 issued on May 27, 2011)
Special Condition #3 (a) specifies that no maintenance event can be initiated unless one or both of
the following thresholds as stipulated in the Final EIS, have occurred: 1) only if shoaling of the
new channel totals 85% of the actual dredged volume of the initial construction and/or 2) only if
the cannel thalweg migrates outside the 500 -foot wide corridor established during the initial
construction.
Hydrographic survey data collected within the limits of the realigned channel since the project was
constructed have been compared to determine shoaling of the realigned channel. The results of
the April 2015 channel survey showed the initial dredge volume had been exceeded by the shoaled
volume by approximately 12%. The April 2016 results show the volume within the footprint of
the realigned channel decreased by' 7% in the past year (105% of the initial channel dredge
volume).
The monitoring results of the April 2016 hydrographic survey show that the thalweg, or deepest
portion of the channel, remains northeast of the preferred channel corridor and is in a similar
position observed in April 2015. Although both channel maintenance thresholds were exceeded
in April 2015, the federal permit for the project does not allow channel maintenance to be
performed more frequently than once every four years. This would make November 2016 the
earliest date channel maintenance could be initiated.
Since the conditions for a channel maintenance to occur have be met, the Town is preparing for
the 3`d Event of the Shoreline Protection and Inlet Management Plan. Based on annual monitoring
of the channel realignment project and the results of the Delft3D modeling analysis, the Town is
proposing to modify the permitted channel design for the upcoming project. The proposed
alternative channel alignment is pivoted approximately 17 degrees to the east as compared to the
original channel dredged in 2012/2013 and terminates at the -18 ft. contour (Appendix A). The
width and depth of the modified channel are the same as the originally permitted channel at 500
ft. wide and -18 ft. NAVD88 respectively. Based on the April 2016 bathymetry, approximately®

700,000 cy would need to be excavated to construct this channel. The beach compatible material
would be placed along approximately 3.63 miles of the Town's oceanfront shoreline. See
Appendix A for plan details.
Cops
Construction of the project would take place during the environmental window from November
16 through March 31.
2.1.13 Geotec anlcal Evulvntion.s
Section (3) (a) of Rule 15A NCAC 071-1.0312 requires that sediment completely confined to
permitted dredge depth of a sediment deposition basins within the inlet shoal system has
an average percentage by weight of fine-grained (less than 0.0625 millimeters) sediment less than
10%. An evaluation of vibracore data collected in 2003, 2006, 2008, and 2016 show the sediment
in the proposed channel maintenance areas meet these criteria. Composite data for the channel
dredged in 2012/2013 had an average composite percent by weight of fine-grained (less than
0.0625 millimeters) material of 1.53% based on vibracores collected in 2003, 2006, and
2008. Furthermore, 10 vibracores obtained in 2016 from within the footprint of the proposed
channel show that the proposed channel has an average composite percent by weight of fine-
grained (less than 0.0625 millimeters) material of 1.02% The composite percent fine grained
material for the existing beach sampled along the east end of North Topsail Beach is 1.72%.
Therefore, this compatibility analysis verifies that the borrow area material meets the allowable
limits defined by the Technical Standards. See Appendix F for the complete sediment
compatibility analysis.
To identify submerged cultural resources within or in the vicinity of the original ocean bar channel,
magnetometer and sidescan sonar surveys were conducted in 2005 and 2007 by Tidewater Atlantic
Resources, Inc. (TAR). The original channel alignment was designed to avoid potentially
significant magnetic anomalies identified during these surveys. The newly proposed pivot channel
design will also avoid the magnetic anomalies identified in the 2005 and 2007 surveys. A portion
of the southwest corner of the proposed realigned channel falls outside of the areas previously
surveyed by TAR. Therefore, additional surveys were conducted to cover that portion of the
channel. See Appendix E for the complete report.
