9. PROJECT DESCRIPTION:
The Town of Topsail Beach has an east facing beach on the south end of Topsail Island, Pender County
with the Town of Surf City to the north and Topsail Inlet to the south. It is also bordered by Banks
Channel to the west and the Atlantic Ocean to the east.
A State CAMA/Dredge & Fill Permit (No. 22-09) was issued to the Town of Topsail Beach for beach
nourishment in 2009 (SAW 2006-40848; and DWR Project #2008 1615). The local project was initiated
by the Town after efforts to implement a federal nourishment project were delayed. A federal project
(designated as the "West Onslow" project) was first authorized by Congress in 1992. In 1994, the Town
withdrew its support and the project stalled. The Town later requested the project be reactivated in 2000
and it was reauthorized by Congress. In light of the unknowns associated with the timing of federal
project appropriations and final implementation, the Town decided to also work on a locally funded and
permitted project to be able to respond to losses from a storm event or erosion in the interim. At that time,
the Town's project was conceived as a one-time event to allow them to protect their beach and
infrastructure until the federal project was implemented. However, federal project efforts stalled, and it
was never initiated.
The Town's permitted project first authorized Borrow Area X as the sand source for the beach
nourishment. Borrow Area X was identified by the US Army Corps of Engineers as the initial sand source
for the federal project. The permit was then modified in 2010 to eliminate use of Borrow Area X and
authorize the use of navigation channels and upland sand sources as the borrow areas. The project was
constructed in the winter of 2010/2011. It placed approximately 1 million cubic yards (mey) of material
along the beach project area. Fill material was excavated from upland disposal areas DA 203, DA189, as
well as portions of Topsail Creek, Banks Channel and what is now known as the Cut Through Channel
(although the latter is not a federally authorized channel). Other than the Cut Through Channel, dredging
followed the US Army Corps of Engineers' federal channel dimensions. Additional projects were
permitted and constructed in 2013 and 2014-2015, with continued use of the federal channels and New
Topsail Inlet (also federally authorized) as the borrow areas. The modification request in 2013 (issued in
2014) also included a proposed increase in the dredge depth and width of Topsail Creek and what is now
called the Connector Channel (then called the "crossover channel") along with increasing the dredge
depth of New Topsail Inlet. The modification increased the permitted dredge depth from -7'+2' Mean
Low Water (MLW) to-14'+2' MLW in Topsail Creek and -16' +2' MLW in the Connector Channel. It
also expanded the permitted dredge width of both channels from 80' to 150'. The authorized dredged
depth for New Topsail Inlet was also increased from -8' +2' MLW to -16' +2' at that time. The permit
was most recently modified in 2018 to maintain the channels and further increase the width of the
Connector Channel and Banks Channel as well as the authorized depth of Banks Channel. That project
was constricted over two winter seasons in 2019/20 and 2020/21. The long-term erosion rate for the
proposed project area ranges from approximately 0-0.7'/year.
The previously authorized placement area extends the entire span of the developed shoreline and slightly
north of the Town limits, a total distance of 24,000'. The beach fill template included a variable width
berm constructed to an elevation of+5' NAVD 88 and a 1:25 slope. Dune construction was not included
in the early projects, but an engineered "dune" (or emergency berm) was built during the last 2019-21
project.

The native beach has been previously characterized with fines calculated at less than I%, and a mean
grain size of 0.24 mm. Calcium carbonate was calculated at I I % and gravel and granular material were
also each calculated at less than 1%. Large sediment and shell material transect sampling was conducted
in July 2023 in accordance with the new requirements of 15A NCAC 07H .0312. A total of 149 shells
greater than 3" and 63 sediments greater than 1" were found along six (6) 10,000 square foot transects
sampled from the toe of dune to mid -tide, resulting in a calculated average of 25 shells and 10.5 rocks per
10,000 square foot area.
The waters in the project area fall within the White Oak River Basin, as classified by the NC Division of
Water Resources (DWR). The waters of Topsail Inlet to Topsail Sound are classified as SA by the DWR.
The NC Division of Marine Fisheries has not designated the vast majority of the areas to be dredged as a
Primary Nursery Area (PNA); however, a portion of the southern section of Topsail Creek and the
northernmost end of the Cut Through Channel are designated as PNA.
PROPOSED PROJECT:
The applicant is proposing to reauthorize the lateral limits of the previously permitted beach nourishment
project along the Town's developed shoreline using sand dredged from Topsail Inlet, a portion. of Topsail
Creek, the Banks Connector Channel and the Cut -Through Channel with the intention of constructing the
project this upcoming winter. The project site extends along approximately 4.5 miles (24,000') of
oceanfront shoreline.
As proposed, the beach berm would be filled to an elevation of+5' NAVD88 with a 25:1 slope out to tie
into existing grade at approximately -5' to -8' NAVD88 with 0.5' of tolerance above and below proposed
grade. The beach berm would be constructed at a variable width ranging from—125-175'. No "dune"
construction/repair or emergency berm construction is included in the beach fill design. As proposed, a
maximum excavated volume of up to 1,630,660 cubic yards of sand is anticipated to be dredged based on
current conditions. It is currently estimated that 161.9 acres would be filled below MHW. Up to 75.9
acres of beach fill material would be placed above the MHW line. Because the last project has held up
reasonably well, the current design would result in a wider beach berm and would increase the project
footprint waterward of the last project, but there is no lateral change to the beach fill area limits_
However, as with all these types of projects, the final fill design is subject to conditions at time of
construction and additional erosion occurring in the next few months may shift the template Iandward
once again to some degree.
Dredging would be conducted via a hydraulic (cutterhead) dredge and plans show pipeline routes would
cross over the island and under the road through existing permanently installed sleeves at Drum St and at
Queens Grant and existing emergency accesses would continue to be utilized for equipment access to the
beach. The applicant states construction would be confined to the previously permitted environmental
window.
The applicant is proposing borrow sites to dredge within Topsail Znlet, a portion of Topsail Creek, Banks
Connector Channel and the Cut Through Channel. Dredging would conform to previously authorized
channel dimensions. The borrow area is currently estimated to contain approximately 1.6 mcy of material.
Because this is proposed maintenance of previously dredged navigation channels, vibracores have been
performed for past projects and the project engineer has certified the ;material conforms with state
sediment compatibility standards. The average composite gravel content for material within proposed
dredge depth

has previously been determined at 1.23%, the average granular content of 1.73%, average fines content is
—0.1% and average calcium carbonate content was 13.24%.
Cultural resource investigations were previously conducted for past projects in 2013 by Tl Coastal and in
2018 by Tidewater Atlantic Research.
An interagency meeting for the project was requested by the applicant in May, but due to lengthy
scheduling delays, has not yet been held. A meeting for the Town is scheduled for August 8. Pre -filing
notification was sent to the Division of Water Resources on 6/28/23,
10. ANTICIPATED IMPACTS
The proposed dredging associated with the project would result in excavation of approximately 97.2 acres
of submerged bottom within the navigation channels. The project would result in the fill of approximately
75.9 acres of upper beach (above MHW) and would fill approximately 161.9 acres of intertidal area and
nearshore shallow bottom (below MHW). The dredging and beach fill would result in temporary
increases in turbidity. Temporary impacts to benthic and invertebrate infaunal communities can be
expected. The applicant states they propose to dredge within the previously permitted environmental
window.

Location
Topsail Island is a developed barrier island in southeastern North Carolina in Onslow Bay. The island consists of
three separate municipalities — North Topsail Beach, Surf City, and Topsail Beach. This project is confined to the
Town of Topsail Beach and is bounded on the north by Surf City, the west by Topsail Sound, the south by New
Topsail Inlet, and the east by the Atlantic Ocean. The island and Town are accessible to the public by highways
50 and 210 with highway 50 being the only main road to the Town of Topsail Beach. The approximate
geographic coordinates of Topsail Beach are Latitude 34' 22'10" and longitude 77°37'30".
Navigation dredging with beneficial use of the shoaled material is proposed for the same channel configuration
as previous Topsail Beach projects and is focused on New Topsail Inlet, Topsail Creek, the Cut Through Channel,
Banks Connector Channel and the southern end of Banks Channel. The dredge portion of these channels is
limited to shoaled portions to restore the channel system to conditions at the completion of the 2019-2020
dredge and beachfill project. The placement area of Topsail Beach includes approximately 4.5 miles of ocean
beach within the Town limits, covering the developed portion of the oceanfront beach (just north of Serenity
Point to the Surf City town line).
History
In the 2000's to 2010's, Topsail Beach work diligently to establish a beach management plan for adaptive
management of the channel system and beach nourishment, enabling internal control over design elements,
project triggers, and financial burdens. The development for this project stemmed from a stalled Federal beach
nourishment project and the subsequent progression of a sustainable internal project that identified renewable
sand sources within the adjacent navigation channels. Dredged sand from the channel system provides a dual
purpose project —increasing safe navigation for vessels around the Town of Topsail Beach by removing shoals
and beneficially use the sand to restore the dune system to what existed prior to the 1990's hurricane
impacts/provide Federal Coastal Storm Damage Reduction Project (CSDR Project) level protection to the
community.
The full scale, privately funded CSDR project finally went to construction in 2019, placing approximately 2.6
million cubic yards of sand on the oceanfront beach, constructing a new primary dune system and wide berm. As
mentioned above, sand was dredged from the Federally authorized channels surrounding Topsail Beach,
however the channel widths and depths were increased to provide capacity for shoaling and an estimated
return period for work of 4-5 years. Due to the size of the project, it could not be completed in one
environmental window —work over the winter of 2019-2020 included dredging in New Topsail Inlet, Banks
Connector Channel, the southern end of Banks Channel, and Side Channel 1. The second phase took place from
November 2020 to March 2021 and dredged sand from Topsail Creek, the Cut Through Channel, the northern
section of Banks Channel, and Side Channel 2. Upon completion of this project, the new primary dune system
was planted with Sea Oats (Uniola paniculata), Bitter Panicum (Panicum amarum), Saltmeadow Cordgrass
(Spartina patens), Beach Elder (Iva imbricate),Common Purslane (Portulaca oleracea), and Gulf Croton (Croton
punctatus). The new primary dune system remains in very good shape and has gained 1-2' of material on the
dune crest and within the valley.

Purpose
Post construction monitoring of the 2019/2020 projected included several triggers for renourishment or
dredging projects encompassing temporal, channel shoaling, or beachfront erosion driven thresholds. This
maintenance cycle has been triggered by both temporal and channel shoaling factors. The monitoring/ beach
management plans dictates that no more than 5 years shall pass between nourishment/dredging cycles in order
to adequately maintain the targeted borrow areas, primarily the inlet ebb shoal, while also allowing them to
"recharge" with sediment following a nourishment event. New Topsail Inlet was dredged in late 2019 and a
project in late 2023 is at the end of the return period for work. This temporal cycle also aligns with the USACE
GRR report (2006) recommended event period of 4 years. The second trigger for the project is channel
shoaling —which is defined as any portion of the interior channel systems becoming less than 7' MLW deep OR
the inlet ebb shoal becoming less than 8' MLW deep. Currently, the permitted inlet channel is shoaled to
approximately 3-4' MLW depths across the ebb shoal. To temporarily alleviate the navigation hazard that exists,
the USACE sidecast dredge recently attempted to open a small pathway offshore, but was hampered by rough
sea conditions and could not connect to deep offshore water. A large scale dredge event is the best solution to
restore safe navigation in New Topsail Inlet. Recent surveys have shown hot spot shoaling within Topsail Creek,
the Cut Through Channel, and Banks Connector Channel has created mean low water depths in the 6-7' range,
which is right at the threshold limit for interior channel dredging. The purpose of this project is to continue the
maintenance of the Topsail Beach interior channel system and provide a high level of coastal storm protection to
oceanfront homeowners and Town infrastructure. This request is for a one time event to be completed within
the permitted environmental window, replicating the project that was originally permitted in 2019 and
completed in Spring 2021.
Project Description
Previously permitted channel dimensions, including alignments, widths and depths will remain the same for this
project. The overall impact areas within the channel system are restricted to the shoaled portion of the
channels —specifically New Topsail Inlet from station 35+00 to 82+00 (4,700 linear feet of channel), Banks
Connector Channel from 0+00 to 37+79 (3,779 linear feet of channel), the Cut Through Channel from 5+00 to
19+00 (1,400 linear feet), and Topsail Creek from 39+00 to 60+00 (2,100 linear feet). Recent conditional surveys
of the channel system show that approximately 1.6 million cubic yards exists within these channels, broken out

The placement area for the dredged sand is the oceanfront shoreline within the municipal limits of Topsail
Beach. The current dune system is in good shape and baring any significant impacts from tropical cyclones this
fall, this proposed project does not include any dune work. The beachfill will consist of rebuilding the upland
berm and beach slope and mimic previous design elements. The berm elevation will be at 5.0' NAVD88 (with
half a foot tolerance above and below design) and the front slope will be 25H:1V, replicating the natural slope of
the beach in Topsail. The total volume of sediment within the channel templates dictates the berm width, and
currently the design is for a 125' to 175' wide upland berm. The northern and southern terminus of the beachfill
will consist of a 300-foot-long taper section transitioning from the existing beach width to the proposed fill
template. Additionally, the area directly adjacent and beneath the Jolly Roger fishing pier will consist of a 25- to
50-foot-wide berm.
The project will place beach compatible sand as defined by the NC CAMA (15A NCAC 07H.0312) guidelines on
approximately 24,000 linear feet of beach within town limits. Due to the historical nature of this project and
dredging from the same channel orientations (2011, 2015, 2019-2021), confidence is high that all shoaled
material in the proposed borrow area will comply with CAMA/CRC definitions of beach compatible material and
no vibracoring is necessary beforehand to verify the quality. However, we will still adhere to the daily sediment
sampling and testing of placed material and submit grain size analysis/calcium carbonate in the daily reports.
The previous dredge and beachfill plan utilized adaptive management and performed as expected, keeping the
navigation channels open and the Town protected over the past 4 years and through the hurricane impacts of
Dorian, Isaias and Ian. It should be noted that not a single dune crossover (wooden stair structure) was lost or
damaged from the oceanfront shoreline since the 2019/2020 project was completed. Additionally, no
detrimental impacts were observed to intertidal shoaling, marsh habitat, or tidal levels from the previously
dredged channel alignment. The currently proposed beachfill and channel dredging scope replicates the
previous work and looks to build on the success of the Topsail Beach nourishment project/management plan
with minimal environmental impacts.

DWG NAME: Topsail Beach Construction Plans 2023.dwg
DWG DATE: May 10, 2023 1 SURVEY DATE: May 2023

SHEET: 26 OF 26

In accordance with guidelines in applying for a Major Permit Modification through the Coastal Area
Management Act (CAMA) offices of the North Carolina Department of Environmental Quality (NCDEQ),
the applicant must notify the adjacent property owners of their application and what the proposed
project consists of. Utilizing aerial photography and the Pender County Online Tax GIS Database,
adjacent property owners and their home mailing addresses were determined for either end of the
project impacts area.
On the south end of the project area, a portion of the beachfill taper section crosses into the community
of Serenity Point. The beachfill design tapers into natural grade at this location because housing
structures within this area begin to pull away from the primary dune and the need for beachfill
diminishes. Extending a line perpendicular to the end of the beachfill reveals that the property owner
adjacent to the end of the southern taper is a duplex building owned by Mr. Edward Lamay and Dr. Urs
Leuenberger. The northern end of the beachfill taper extends slightly into the Town of Surf City, ending
just north of the Project Bumblebee tower. The oceanfront property located here is vacant land and
therefore notification was sent to the Town of Surf City.
This notification package includes a full copy of the permit application and as per protocol for this
notification, the notification package was sent via certified mail with return receipt and instructed to
send any objections or concerns in writing to Ms. Heather Coats with NCDEQ. Locations of the property
owners dwellings, letters to the homeowners and receipts of the certified mail packages can be found
below.

SEDIMENT COMPATIBILITY ANALYSIS COMPLIANCE CERTIFICATION
Jamie C. Pratt, PG being licensed pursuant to Chapter 89E of North Carolina General Statutes,
hereby certifies that the sediment compatibility data and analysis of dredge material within New Topsail Inlet,
Banks Connector Channel, the Cut Through Channel and Topsail Creek complies with the sediment standards
found within 15A NCAC 07H.0312. Multiple vibracore/sediment testings efforts prior to projects in 2010, 2011,
2014, and 2019 have demonstrated the previously dredged sediment infills with beach quality sediment. The
2023/2024 project is identical to previous project template design and therefore the sediment is expected to
remain high quality and extremely compatible with the native sand. In lieu of additional coring and analysis,
project history and demonstration of highly compatible sediment through repetitive dredge events shall serve
as verification of the proposed borrow area sediment quality.

Topsail Beach Large Clasts Analysis
TI Coastal conducted a Large Clasts evaluation of Topsail Beach for Shells greater than or equal to three
inches and Rocks greater than or equal to one inch. The search area consisted of six, ten thousand sq.ft.
areas spread evenly on 5,000 foot intervals and centered on the historic monitoring profiles within the
town limits of Topsail Beach. This specification was outlined in section 15A NCAC 07H .0312 of the
"Technical Standards for Beach Fill Projects", subsections (C) and (H). The cross -sectional profiles
searched are TB00+00, TB50+00, TB100+00, TB150+00, TB200+00 and TB239+68 (the last cross -sectional
profile within the town limits of Topsail Beach). The crew used a 5'x5 PVC square guide to establish a
twenty five sq.ft. search area to eliminate the potential of double counting (Figure 1), along with a three
inch tool with a one inch mark for measuring shells and rocks (Figure 2).
The designated search area was derived from the distance from the eight foot contour, representing the
toe of the dune to the zero foot contour (mean tide level) for every 5,000' transect. That distance was
then used as the length of the search area for that specific perpendicular profile. The width of the
search area was formulated by dividing ten thousand by the length of the search area. Once the desired
search area was found the 10,000 square foot search boxes were drawn in AutoCAD and the northing
and easting values for the four corners of the search area were keyed into a Trimble TSC3 survey
controller to be staked out with flagging in the field(Figure 3).
The crew aligned the first guide with the corner touching the flag indicating the first corner of the search
area. Once the guide was aligned, the remaining three guides were placed in line with one of the guides
axis aligned with the eight foot contour (Figure 4). Each twenty five sq. ft. area was examined and any
shells greater than or equal to three inches and rocks greater than or equal to one inch were recorded
(Figure 5). Once the shells and rocks in the search grid were recorded, the crew flipped the guide on its
seaward axis and repeated the process until the zero foot contour was reached (Figure 6). That process
continued until the whole ten thousand sq. ft. search area was examined.
After the completion of the search area the crew would stake out the next cross-section profile and
repeat the process. The number of large clasts found in each search area has been detailed below in
Table 1. A total of 149 shells greater than 3" were found along the Topsail shoreline, averaging 25 shells
per 10,000 square foot area. There were 63 rocks greater than 1" in diameter, averaging 10-11 rocks per
10,000 square foot area. An interesting note is that almost all large clasts were located between the
berm line and the toe of the dune —the beachface and intertidal aera between mean high water and
mean tide level contained little to no large clasts.
