8. PROJECT SUMMARY:
The proposed project is for a living shoreline that would be constructed in four sections
totaling 3,520 ft. It would be placed along the mainland of the Hammocks Beach State Park
shoreline.
9. NARRATIVE DESCRIPTION:
The Hammocks Beach State Park project is located at 1572 State Road 1511, Swansboro,
Onslow County.
The mainland property is 290 acres in its entirety. Queen Creek runs along the west side of the
property. The property is cleared at some locations with a visitor center, campsites, trails,
maintained lawn grass, parking lots, roads, and existing living shorelines, a docking facility
and boat ramp in section CL There is also an existing bulkhead and docking facility in section
B. There are coastal wetlands along the entire shoreline, which consists mostly of Distichilis
spicata, Limonium carolinianum, Juncus roemerianus, Salicornia bigelovii, Scirpus acutus,
Spartina alterniflora, and Spartina patens on Queen Creek.
The Division of Water Resources classifies this area as SA/HQW Waters. This area of Queen
Creek is not designated as a Primary Nursery Area and is open to the taking of shellfish. Water
depths within this project location are-2'nlw/mlw to -3.5' nlw/mlw depending on location. The
bottom substrate is sand and some SAV were observed within the proposed sill area. A SAV
survey was completed by the applicant. Queen Creek is approximately 2,323 feet wide at this
location.
10. PROJECT DESCRIPTION:
The applicant is proposing to install 3,520 feet of living shoreline divided into 4 sections. The
4 sections are B (1,135 ft), C1 (1,150 ft), C2 (782 ft), and C3 (537 ft). According to my
calculations the entire sill will total to 3,604 feet.
Section B extends from the northern park boundary to the south portion of the 4H pier. The
applicant is proposing to install a living shoreline totaling 1,135 feet of combination QuickReef
and Natrx Sustainable ExoForms. This is proposed to have 10 sections with 9 gaps every 100 ft
that are each 5 feet long. 8 of the gaps would be overlapping baffles. The base width would be
6.7ft and 2ft in height. The landward edge of the sill would be no more than 30 ft from Normal
High Water. The water depths in this section are -2.2' to -3.4' at mhw.
Section C1 is located at the Hammocks Beach State Park visitor center and extends from the
existing dock to the existing 500' sill. The applicant is proposing to install a living shoreline
totaling 1,150 feet of combination QuickReef and Natrx Sustainable ExoForms. This is
proposed to have 10 sections with 9 gaps every 100 ft that are each 5 feet long. The gaps would
be overlapping baffles. The base width would be 6.7ft and 2ft in height. The landward edge of
the sill would be no more than 30 ft from Normal High Water. The water depths in this section
are -2.5' to -3.2' at mhw.
Section C2 is located at the northwestern terminus of the existing 500' sill to the bluff below
the existing Hickory Bluffs trail. The applicant is proposing to install a living shoreline totaling
Field Investigation Report: Hammocks Beach State Park - NC State Parks
DCM Major Permit
Page 13

782 feet of combination QuickReef and Natrx Sustainable ExoForms. This is proposed to have
7 sections with 6 gaps every 100 ft that are each 5 feet long. There would be a seventh gap at
the end of the existing sill and the beginning of this proposed sill separating C1 and C2. The
gaps would be overlapping baffles. The base width would be 6.7ft and 2ft in height. The
landward edge of the sill would be no more than 30 ft from Normal High Water. The water
depths in this section are -2.2' to -3.2' at mhw.
Section C3 is located at the bluff shoreline of the FFA camp. This sill would end south of a
small marsh channel. The applicant is proposing to install a living shoreline totaling 537 feet of
combination QuickReef and Natrx Sustainable ExoForms. This is proposed to have 5 sections
with 4 gaps every 100 ft that are each 5 feet long. The gaps would be overlapping baffles. The
base width would be 6.7ft and 2ft in height. The landward edge of the sill would be no more
than 30 ft from Normal High Water. The water depths in this section are -2.3' to -2.9' at mhw.
11. ANTICIPATED IMPACTS:
The proposed development would fill and usurp 23,584 ft2 of shallow bottom habitat. There
would be no filling of coastal wetlands or SAV. All portions would be at least 10' from any SAV.
The increase in suspended sediment and turbidity levels from the sill placement would be
temporary, occur while the sill placement is taking place and should be minimal given the bottom
composition. The proposed additions should not be a hindrance to navigation due to the fact all
portions would be located landward 1,305' from the USACOE channel setbacks. The proposed
development would also meet the minimum 15' setback from the riparian access lines and not
exceed a maximum distance of 36.7' waterward of NHW (includes base width).

Buildings/Facilities/Units/Structures:
living shoreline offshore sill
Use & Daily Operations:
shoreline protection
Construction Methodology & Equipment:
Construction will be accomplished by either barging materials to the site or accessing the area from existing roads. Pallets of
QuickReef m and Natrx Sustainable ExoFormsTM will be barged to the site and offloaded into the water using a crane or trucked to the
site and lowered onto floating docks or directly into the water by a crane. Material may be transported along the existing marsh as
needed using a low -impact, low ground -pressure forklift. If material needs to be stockpiled along the shore or any material needs to
be transported by land over coastal wetlands, plywood and/or logging mats will be placed over existing coastal marsh for the time
required to travel across it or temporarily stockpile materials to prevent deposition of fill and dissipate any impacts. No material will
be set on existing coastal marsh for an extended period. All pallets and any other construction materials will be removed from the
site immediately following construction. See attached project narrative for additional information.
Development Activities Narrative Specifics:
See attached detailed project narrative with photos.
Application Narrative:
The subject shorelines on the mainland of Hammocks Beach State Park (HBSP) are
in need of stabilization and restoration due to ongoing, consistent erosion
with no significant accretion of new material to maintain the marsh. Four
shoreline sections totaling 3,520 feet (ft) are proposed for stabilization and
labeled on the attached figures Sheet 1 thru 5 (attached) as Shorelines B, C1,
C2, and C3. Each are described in the attached detailed project narrative with
pictures. No fill or discharge of fill material into any wetland or "waters of
the US" is proposed for this project. Other living shorelines are being
considered for other park properties (separate legal parcels) on Bear and Jones
Islands in the future.

Submerged Aquatic Vegetation Survey Findings
Methods:
A submerged aquatic vegetation (SAV) survey was performed May 2, 2023, by staff from the
North Carolina Coastal Federation, Native Shorelines, and Hammocks Beach State Park. The
survey was conducted within the footprint of the proposed offshore sills and section descriptions
and titles are as referred to on Sheets 1 through 5 of the living shoreline CAMA major permit
application submitted April 18, 2023. Transects were surveyed for vegetation type and percent
cover, starting at the existing marsh edge and running up to 20 feet (ft) from the marsh edge
(Figures 1 and 2). Data were collected at intervals of 5 ft. along the 20-foot transects. The final
sampling point for transect C1-22 was sampled 16 ft from marsh edge rather than 20 ft from
marsh edge due to water depth (Table 1).

Results:
The estuarine bottom including and surrounding the footprint of the proposed offshore sills was
characterized by intertidal muddy sand flats. Oyster shell beds were observed throughout
Shoreline Section B, but were not composed of live oysters (Table 1). Patchy macroalgae
(Gracilaria verrucosa) was observed throughout Shoreline Sections B, C3, and C2 (Figures 3
and 4, Table 1). Seagrass was absent from Shoreline Section B. Zostera marina was present
along Shoreline Sections C3, C2, and Cl, with up to 5%, 50%, and 30% coverage, respectively
(Figure 5, Table 1).

Hammocks Beach State Park Shoreline Areas B & C SAV Survey - May 2, 2023 Page 4 of 6

In Summary:
Neither Ruppia maritima nor Halodule wrightii were observed along the proposed offshore sill
footprint, and Zostera marina was only observed in patches. There were no extensive,
established beds of Z. marina observed. Due to the ephemeral nature of Z. marina in eastern
North Carolina, we do not believe the installation of the proposed offshore sill will be
detrimental to the SAV population or to species that may utilize the habitat.
All available precautions shall be utilized to ensure that damage to SAV habitat does not result
from construction of the offshore sills. To the greatest extent practicable, no sills will be
constructed in areas with SAV coverage at the time of construction. Construction of the proposed
offshore sills is projected to take place outside of the SAV growing season, further ensuring
protection to the minimal SAV that was observed.
Hammocks Beach State Park Shoreline Areas B & C SAV Survey - May 2, 2023 Page 5 of 6

Project Name: Hammocks Beach State Park Shoreline Areas B & C
Project Address: 1572 State Rd 1511, Swansboro, North Carolina (NC)
Owner: State of North Carolina
Non -Project Project Sponsor: North Carolina Coastal Federation
Consultant and Contractor: Native Shorelines, a division of Restoration Systems, LLC
The subject shorelines on the mainland of Hammocks Beach State Park (HBSP) are in need of
stabilization and restoration due to ongoing, consistent erosion with no significant accretion of new
material to maintain the marsh. Four shoreline sections totaling 3,520 feet (ft) are proposed for
stabilization and labeled on the attached figures Sheet 1 thru 5 (attached) as Shorelines B, C1, C2, and
C3. Each are described below further. No fill or discharge of fill material into ony wetland or "woters of
the US"is proposed for this project. Other living shorelines are being considered for other park
properties (separate legal parcels) on Be
Section B - Mitchell 4H Camp
Shoreline Section B (Sheets 1 and 2
attached; Photo 1 right) is located on a
portion of HBSP that was previously used
as Mitchell 4H Camp, originally one of NC
only 4H camps for black North Carolinian!
before desegregation. Section B extends
from the northern park boundary along
Queen Creek with the Swans Bluffs
southeast to just south of the former 4H
recreational fishing pier, which the park
plans to repair and reopen in the near
future. It should be noted that Queen
Creek is closed to shellfishing upstream o
the park/Swans Bluff property line.
The marsh shoreline in Section B is in direct need of
stabilization and restoration due to past use as a
recreational swimming beach and the presence of �<
moderate boat wake traffic in a primary nursery area. TI,:� E'f
shoreline is actively eroding (Photo 2, right) and is expec
to continue to do so as boat traffic increases with
increasing residential development in the surrounding

area. The bluff shoreline behind the marsh was modified and graded so that it could be mowed when
the property was in use as a 4H camp.
The proposed conceptual plan for Section B (Sheet 2, attached) includes construction of 1,135 ft of a
combination QuickReefTr' and Natrx Sustainable ExoFormsT`" living shoreline placed 5 to 30 ft waterward
of mean high water (MHW). The proposed living shoreline will consist of 10 sections of offshore sill
totaling 1,015 with 9 gaps (5 ft long each) placed approximately every 100 ft to maintain consistent tidal
flow, flushing, and passage of fish and other marine organisms. To reduce erosion, eight of the nine gaps
will have overlapping baffles (15 ft long each) totaling 120 ft.
The main portion of the sill in Section B will have a base width of 6.7 ft and a height of 2 ft along the
centerline. The landward edge of the sill will extend no more than 30 ft waterward of MHW and will be
constructed using QuickReefT"^. As the overlapping baffles for the gaps in this structure will be in water
ranging from 2.5 to 3.3 ft in to 40 in deep, Natrx Sustainable ExoFormSM will be used for these sections
with a base width of 6.7 ft and a height of 2.5 ft in along the centerline. Natrx ExoForms can be custom
produced to the height needed for the project so are better suited for deeper water. The waterward
edge of the sill will be marked at 50-foot intervals with yellow reflectors on PVC poles extending at least
3 ft above normal high water and will be maintained for the life of the structure.
NC Coastal Federation and Native Shoreline staff measured water depths at high tide along the Section B
proposed alignment on October 26, 2022. Measured depths ranged from 2.2 ft at the marsh edge to 3.4
ft at 30 ft waterward of normal high water. The average elevations at Station: 8656613, Swansboro, East
Corbett Ave Bridge on the White Oak River just south of Hammocks Beach State Park are 0.16 ft for
mean low water (MLW) and 1.64 ft for MHW, relative to mean lower -low water (MLLW), resulting in a
mean tide range of 1.48 ft relative to MLLW. In no instance will the height of the structure extend more
than 1 ft above the normal high water line.
The proposed living shoreline system will improve intertidal habitat and increase resilience of the
property to storm events. It will also allow oyster recruitment and growth and is intended to generate
an intertidal oyster reef supplementing other reefs located in the general vicinity within Queen Creek
and the White Oak River. There will be no fill placed in the water or in any location waterward from the
mean high tide line. A submerged aquatic vegetation (SAV) survey along Section B has shown the
substrate to be firm sand to sand mixed with fine silt with no SAV present during the growing season.
Following installation of the living shoreline, landward restoration, including removal of a failing and
aged wooden bulkhead (Photos 3 and 4, page 3; to be removed as part of a separate permitting action)
and native riparian plantings in the area of the bulkhead and the pier, will commence.
Construction of Section B will be accomplished by either barging materials to the site or accessing the
area from the former 4H camp roads. Pallets of QuickReefT"^ and Natrx Sustainable ExoFormsT`" will be
barged to the site and offloaded into the water using a crane or trucked to the site and lowered onto
floating docks or directly into the water by a crane. Material may be transported along the existing
marsh as needed using a low -impact, low ground -pressure forklift. If material needs to be stockpiled

along the shore or any material needs to be transported by land over coastal wetlands, plywood and/or
logging mats will be placed over existing coastal marsh for the time required to travel across it or
temporarily stockpile materials to prevent deposition of fill and dissipate any impacts. No material will
be set on existing coastal marsh for an extended period. All pallets and any other construction materials
will be removed from the site immediately following construction.

Photo 6. QuickReef - living shoreline installed in 2022 between
HBSP proposed living shoreline Sections C1 and C2.
Photo 7. Erosion along HBSP proposed living
shoreline Section C1.
The shoreline along Section C1 is rapidly eroding due to boat wakes and bluff erosion during storm
events and king tides (Photo 7, above). As with Section B, boat wake erosion is anticipated to increase as
the surrounding area experiences increasing residential development. Some portions of this section
have fringing Spartina alterniflora marsh but in other areas the bluff shoreline behind the marsh has
eroded and only fringingJuncus spp. marsh remains. Previous S. alterniflora plantings along this section
have failed due to continuing erosion and wrack deposition following king tides and storm events.
The proposed conceptual plan for Section C1 (Sheet 3, attached) includes construction of 1,150 ft of a
combination QuickReefTr' and Natrx Sustainable ExoFormsT`" living shoreline placed 5 to 30 ft waterward
of MHW. The proposed living shoreline will consist of 10 sections of offshore sill totaling 1,000 ft with 9
gaps (5 ft long each) placed approximately every 100 ft to maintain consistent tidal flow, flushing, and
passage of fish and other marine organisms. There are 5-foot gaps included at both ends of the
proposed living shoreline between the new Section C1 living shoreline and the existing living shoreline
structures. To reduce erosion, gaps will have overlapping baffles (15 ft long each) totaling 150 ft.
The main portion of the sill in Section C1 will have a base width of 6.7 ft and a height of 2 ft along the
centerline. The landward edge of the sill will extend no more than 30 ft waterward of MHW and will be
constructed using QuickReefT`". As the overlapping baffles for the gaps in this structure will be in water
ranging from 2.5 ft to 3.2 ft deep, Natrx Sustainable ExoFormsTM will be used for these sections with a
base width of 6.7 ft and a height of 2.5 ft along the centerline. Natrx ExoForms can be custom produced
to the height needed for the project so are better suited for deeper water. The waterward edge of the
sill will be marked at 50-foot intervals with yellow reflectors on PVC poles extending at least 3 ft above
normal highwater and will be maintained for the life of the structure.

NC Coastal Federation and Native Shoreline staff measured water depths at high tide along the Section
C1 proposed alignment on October 26, 2022. Measured depths ranged from 2.2 ft at the marsh edge to
3.2 ft at 30 ft waterward of normal high water. As described above under Section B, the mean tide range
in this area is 1.48 ft relative to MLLW. In no instance will the height of the structure extend more than 1
ft above the normal high water line.
The proposed living shoreline sill system will improve intertidal habitat and increase resilience of the

mixed with fine silt with no SAV present during the growing season. After the living shoreline has been
installed to reduce erosion, riparian plantings will occur landward of MHW.
Construction of Section C1 will be accomplished by either barging materials to the site or accessing the
area from land. Pallets of QuickReefTr' and Natrx Sustainable ExoFormsT"^ will be barged to the site and
offloaded into the water using a crane or trucked to the site and lowered onto floating docks or directly

northwestern terminus of the 500-foot
QuickReefTr' and marl shoreline installed in
2022 (NC Division of Coastal Management
Permit 84404C) (Photo 6, page 4) and ends at
a steep bluff below the Hickory Bluffs trail. The
fringing marsh shoreline in Section C2 is in

life of the structure.
The proposed conceptual plan for Section C2 (Sheet 4,
attached) includes construction of 782 ft of a
combination QuickReefTr' and Natrx Sustainable
ExoFormsT`" living shoreline placed 5 to 30 ft waterward
of MHW. The proposed living shoreline will consist of 7
sections of offshore sill totaling 677 ft with 6 gaps (5 ft
long each) placed approximately every 100 ft to
maintain consistent tidal flow, flushing, and passage of
fish and other marine organisms. There is also a 5-foot
gap included at southeastern end of the proposed living
shoreline between the new Section C2 living shoreline
and the existing QuickReefTr' and marl living shoreline
between proposed Sections C1 and C2. To reduce
erosion, gaps will have overlapping baffles (15 ft long
each) totaling 105 ft. The northwestern end of the sill is
designed to curve around and protect the eroding
marsh point (Photo 10, below left).
The main portion of the sill in Section C2 will have a base
width of 6.7 ft and a height of 2 ft along the centerline.
The landward edge of the sill will extend no more than
30 ft waterward of MHW and will be constructed using
QuickReefT`". As the overlapping baffles for the gaps in
this structure will be in water ranging from 2.5 ft to 3.5
ft deep, Natrx Sustainable ExoFormsTM will be used for
these sections with a base width of 6.7 ft and a height of
2.5 ft along the centerline. Natrx ExoForms can be
custom produced to the height needed for the project
so are better suited for deeper water. The waterward
edge of the sill will be marked at 50-foot intervals with
yellow reflectors on PVC poles extending at least 3 ft

an intertidal oyster reef supplementing other reefs located in the general vicinity within Queen Creek
and the White Oak River. There will be no fill placed in the water or in any location waterward from the
mean high tide line. A SAV survey along Section C2 has shown the substrate to be fine silty sand to mud
with no SAV present during the growing season. After the living shoreline has been installed to reduce
erosion, riparian plantings will occur landward of MHW.
Construction of Section C2 will be accomplished by barging materials to the site. Pallets of QuickReefT"^
and Natrx Sustainable ExoFormSM will be barged to the site and off loaded into the water using a crane.
If material needs to be stockpiled along the shore or any material needs to be transported by land over
coastal wetlands, plywood and/or logging mats will be placed over existing coastal marsh for the time
required to travel across it or temporarily stockpile materials to prevent deposition of fill and dissipate
any impacts. No material will be set on existing coastal marsh for an extended period. All pallets and any
other construction materials will be removed from the site immediately following construction.
Shoreline Section C3 — Former FIFA Camp/Future State Park Family Campground
Shoreline Section C3 (Sheets 1 and 5,
attached; Photo 11 right) extends the
length of the bluff shoreline of the former
Future Farmers of America (FFA) camp,
soon to be a state park family
campground. The sill will terminate at a
point just south of a small marsh channel
to allow campers' kayaks and
canoes to reach the open water.
The fringing marsh shoreline in
Section C3 is in direct need of
stabilization and restoration due to ,
boat wake that is rapidly eroding
the S. alterniflora marsh and the
landward bluffs (Photo 12, right).

Project Funding and Timeline
This project is proposed now to take advantage of living shoreline cost -share funds allocated by the NC
General Assembly in 2022 to the NC Coastal Federation specifically for this and other NC State Park
living shoreline projects. These funds are unprecedented in value with a limited time frame for
expenditure and protection of these shorelines would not be possible without the use of these funds.
