8. PROJECT SUMMARY: The applicant proposes to construct a 166 slip marina resort
style community including single family residences, townhomes, condominiums, and
supporting light commercial around an existing 10-acre lake (reclaimed sand mine),
which is proposed to be connected to the Albemarle Sound via a 60 feet wide 8.0 feet
deep navigation channel cut through USACE jurisdictional 404-wetlands and open
water bottom substrate.
Project Setting
The project site is located at 291 West Side Lane (Parcels A & B), Powells Point, Currituck
County, and is adjacent to the Albemarle Sound.
Parcel A is ±15.95 acres and Parcel B is ±104.2 acres in size (±120.15 acres cumulatively) with
most of the property (+/-86 acres) being a mix of wetlands with approximately 20 acres of
uplands surrounding an existing reclaimed sand mine lake (barrow pit) excavated in the 1970's.
Much of the uplands are maintained grasses, pines, with unimproved soil paths and roads.
There is a single-family residential home on the property along with horse barns and paddocks.
An existing highground soil road extends from the upland area adjacent to the lake to the
shoreline area.
The existing lake is ±1,450' in length and ±328' in width (±10.9 acres) and is oriented in a
north/south direction and is located >_1,150' inland from the Albemarle Sound shoreline. Existing
water depths within the lake range from ±3' to ±17' in depth with an average of ±13'.
There are two major wetland types found on site, Riverine Swamp Forest, and Salt/Brackish
Marsh with areas of open water. A large swath of Salt/Brackish Marsh (+/- 42 Acres) has been
overtaken by Phragmites australis that likely gained a foothold during mining and canal digging
that occurred on the property in the past (1970's). The remaining portions of Salt/Brackish
Marsh have been delineated as coastal wetlands and are predominately comprised of sawgrass
(Cladium jamaicense). At one time in the past, the canals dug through the marsh connected to
the Albemarle Sound; however, the remnant canal system is no longer directly connected to the
Sound due to the natural formation of sand berms along the shoreline.
The project site has ±1800' of shoreline immediately adjacent to the Salt/Brackish Marsh. The
shoreline has areas where the wetlands extend to normal water level (NWL) as well as areas
that are a sandy beach that ranges in width from several feet to ±20' in width with elevations of
1' or less. There are no existing man-made structures located along the shoreline. The adjacent
riparian properties are both undeveloped and similar in wetland composition as the project site.
The waters of the Albemarle Sound in this area are considered Coastal Waters, classified as
SB, are not considered a primary or secondary nursery, and are closed to shellfish taking. Open
water fetch along the project sites shoreline ranges from ±10 to 50 miles. The bottom substrate
is sand dominated overlying clays, peat and clayey sands. Near shore areas are predominately
relic peat beds with scattered stumps and wood debris originating from the eroding shoreline.

There are also small gravel beds found in some locations along the shoreline/near shore areas.
Some small areas of exposed clay exist just past the areas of peat in the near shore. Water
depths within the project area range from inches along the shoreline to ±8' below NWL at a
distance of ±1,674' waterward of NWL along the shoreline. A Submerged Aquatic Vegetation
(SAV) survey was conducted by Quible & Associates, P.C. on August 1, 2022 (see Attachment
G) in which only one small sparse patch of SAV was found within the project area.
Development Proposal
The applicant proposes to construct a 160 unit marina resort style community that includes
single family residences, townhomes, condominiums, and supporting light commercial around
the existing 10-acre lake (boat basin), which is proposed to be connected to the Albemarle
Sound via a 60 feet wide and 8.0 foot deep navigation channel.
The creation of the marina involves first connecting the existing lake (boat basin) to the
Albemarle Sound via a ±1,454' x 60' wide box cut (centerline measurement) canal excavated
through both uplands and Phragmites dominated wetlands. The existing lake has waterdepths
that are deeper than the proposed connecting water depths of -8.0 feet (relative to NWL).
Therefore, ±1 acre of lake will be reshaped to form a more oval shaped basin and the bottom
profile filled to achieve a depth of -8.0 ft (NWL).
Excavation of the canal will begin at the upland "neck" of the proposed boat basin, first cutting
through ±197' of uplands (in a Y-shaped cut), then ±1,096' of USACE jurisdictional wetlands
and then through ±161' of upland shoreline area. It will be mechanical and performed by
excavators on barges that will load material onto scows located behind (basin side) the
excavator. Loaded scows will be pushed by boat into the basin area and the excavated material
will be emplaced around the basin to achieve the proposed water depths (±65,000 cu. yds. of
material). A plug that is ±40' to ± 50' in thickness will be left separating the canal and basin from
the Albemarle Sound. The applicant has indicated that the contractor will stop all excavation of
the uplands and canal for a period of approximately two weeks to allow for settling of any fine
materials. Turbidity measurements are to be taken to ensure that water quality has stabilized
prior to making any connection to the Albemarle Sound. Additional basin shaping may occur
during this time. Once the water quality in the basin and canal have stabilized (turbidity < 10
NTU's or as required) dredge operations will proceed through the "plug" and into the Albemarle
Sound a distance of ±1,674' from the shoreline to the connective water depth of -8.0 ft.
Sediment curtains will be used as necessary to ensure that turbidity in the Albemarle Sound
does not exceed NTU requirements. Dredge spoils are anticipated to be comprised of sand,
clay, peat and muck. This material will be placed in two 150' x 100' spoil containment areas
located within the upland area on either side of the proposed canal connection to the basin.
Dredge spoils will be segregated within the containment areas and unsuitable materials will be
transported via sealed dump trucks to an offsite disposal area/mining operation with an active
SESCP or DEMLR mine permit. Suitable materials will be dried and used as fill material forthe
lake and construction in the upland area. The applicant has submitted documentation in regard
to a Hydrodynamic and Water Quality Flushing Model (see Attachment C). Based on the
reported results of the flushing model and input from SOLitude, 12 aeration heads are proposed
to be placed around the marina as shown on Sheet 3 of the development plans. Air would be
pumped through tubing to the submerged heads at a predicted and modeled rate of475 kg/day.
Technical information related to the proposed aeration system is included in Attachment C.

The applicant proposes to monitor dissolved oxygen within the marina basin and channel at
seven monitoring stations on a monthly basis with weekly monitoring during June, July, August,
and September (warmest four months of the year). A monitoring plan and proposed monitoring
locations are included in Attachment F. Monitoring of DO would be performed to ensure DO
concentrations are as predicted in the modeling and allow the marina operator to adjust the
diffused aeration system to optimize DO levels in the marina.
Two navigation channel markers are proposed to be installed along the open water channel to
guide vessels to the canal.
Two bulkheads measuring 251' and 213' are proposed along the upland section of the channel
cut at the mouth of the basin to stabilize the channel entrance to the basin. These bulkheads
will transition to slotted breakwaters with 1" gaps per linear foot (or equivalent) at the wetland
interface and will run along each side of the canal cut through wetlands extending to the
Albemarle Sound shoreline (due to the angle of the proposed canal, the northern edge of the
canal would measure 1,256 linear feet and the southern edge would measure 1,244 linear feet).
These breakwaters are proposed to help stabilize the channel, dissipate wave and boat wake
energy, but still allow water to flow into and out of the adjacent wetlands. The applicant has
indicated that bulkheads and breakwaters will be constructed prior to the canal and basin being
connected to the Albemarle Sound.
The two breakwaters will transition to solid jetties at the shoreline extending out 150 linear feet
along both sides of the open water channel. In addition, jetties of tapering lengths are proposed
on each side of the open water channel measuring 80 and 55 linear feet spaced 50 feet apart.
There is considerable near shore sediment transport and thejetties are proposed as a measure
to limit channel dredge maintenance.
A soil parking area is proposed near the shoreline within highground area adjacent to the
existing soil road. Two kayak racks are proposed within this area as well as a 250' x 6' wide
accessway extending from the parking area over phragmites wetlands to the shoreline,
transitioning to a 200' x 6' wide pier with a 50' x 20' wide t-head platform in open waters of the
Albemarle Sound.
Within the waters of the basin, 166 total boat slips with accompanying piers and finger piers are
proposed. This would accommodate one slip for each residence in the community and six slips
for transient use. A total of 11 docks are proposed and include (see corresponding dock
numbers on sheet 3 of site plans):
(1) 141' x 8' floating dock with one 5' long x 8' wide access pier,
(2) 145' x 8` floating dock with one 5' long x 8' wide access pier,
(3) 123' x 8' floating dock with one 75' long x 6' wide access pier,
(4) 340' x 8' floating dock with two 6' long x 8' wide access piers,
(5) 119' x 8' floating dock,
(6) 326' x 8' floating dock with two 8' long x 8' wide access piers,
(7) 160' x 8' floating dock with one 8' long x 6' wide access pier,
(8) 160' x 8' floating pier,
(9) 558' x 10' floating dock with fueling facilities,
(10) 396' x 8' floating dock with three 8' long x 8' wide access piers,
(11) 177' x 8' floating dock with one 10' long x 8' wide access pier

Page 5 of 7
A total of 122 floating finger piers are proposed on the above docks:
• (34) 12' x 3'
• (81)20'x3'
• (7) 25' x 3'
Fueling facilities are proposed along Dock 9. Two dispensers are proposed along the dock with
a fuel line connecting to two underground storage tanks (USTs) located under the proposed
parking area adjacent to the boat ramp (described below) and docking facility. Sewage pump -
out will be offered for the marina. The pump out will be connected to the proposed wastewater
treatment facility that will service the community. "No Overboard Discharge/Sewage Pump out
Available" signs will be placed on each of the 11 docking facilities in visible locations.
A public boat ramp is proposed to be constructed adjacent to a proposed restaurant. The
concrete ramp will extend 52' beyond NWL and will have a 20' width. It will be poured and
cured on land and placed into the water once the concrete is dry. No live concrete will be
poured below NWL. A 32' x 6' staging pierwill be constructed adjacent to the boat ramp to help
facilitate launching and recovery of vessels.
A 2,518' x 6' wide wooden boardwalk with 13 accessways (varying from 15' to 36.5' in length),
and elevated 3 ft above wetland substrate, is proposed to wrap around the basin to offer
pedestrian access to the various piers and slips around the marina. The boardwalk will be
constructed along the shoreline over wetlands, but not over the water. A total of 1,265 ft2 of the
accessways will be over uplands. The shoreline of the basin will not be hardened and a natural
emergent wetland vegetated shelf around the basin will be maintained and promoted. A 105'
bulkhead with two 20' wingwalls is proposed to stabilize the area waterward of a proposed
restaurant.
Proposed community development includes construction of up to 160 total residential units and
all required and associated infrastructure (see sheet 3 of site plans). Residential units will be a
mix oftownhomes (10 buildings), condos (16 buildings), and single-family units (27 buildings).
The proposed marina community includes a ship's store, light retail and a restaurant. As
proposed, the total wetland fill impacts for the upland development are ±20,908 ft2 (0.48 acres);
which includes filling for road crossings and upland fill to achieve the proposed density, provide
adequate stormwater management and provide for all appropriate setbacks. All non -water
dependent structures and impervious areas are proposed to be located landward of the 30'
CAMA Buffer. Impervious areas within the Estuarine Shoreline AEC total 87,389.1 ft2 (14.8%)
and impervious areas for the entire tract total 447,926.8 ft2 (8.6%). Proposed stormwater control
features include a wet pond and constructed wetland areas. The applicant has indicated that an
NC DEMLR stormwater permit will be sought as part of the development pending the issuance
of a CAMA permit.
An existing soil road that extends from West Side Lane across the property to the northwest is a
deeded easement for and sole point of access to the adjacent property to the northwest. This
existing soil road is proposed to be improved with gravel and widened to meet the minimum
required drive aisle widths (20 feet minimum) and all-weather driving surfaces suitable for
emergency vehicles and fire trucks. This road will continue provide access to the adjacent
property as well as provide access to a proposed wastewater treatment plant (described
below). Based on a review of historic aerial photography and USGS topographic maps, this

road has been in use since the 1940's and currently crosses a man-made canal (dug in the
1970's), which appears to have been dug in what was once a natural water course. A County
required 722 LF pedestrian walkway is also proposed along the north side of the improved
gravel road. This walkway will be timber and will not cross any waters.
An existing culvert where this road crosses the canal measures 20' in length and 32 inches in
diameter and is angled incorrectly and in poor condition. This undersized and damaged culvert
does not provide adequate circulation and aquatic passage. A new 35' long 60-inch culvert is
proposed to replace the existing culvert and is proposed to be buried a minimum of one foot
below the existing canal substrate. Excavation of the old pipe is not expected to impact wetland
areas; however, installation of the new culvert will result in the filling of ±351 ft2 of USACE
jurisdictional wetlands. Excavated materials will be placed in a temporary 30' x 30' containment
area within the adjacent highground area.
The development will be served by a proposed 80,000 gpd onsite central wastewater treatment
system to be located on the northeast side of the property. Disposal of all clean effluent from
the facility will be routed onto the adjacent golf course to a pre -approved area. A force main and
pumpstations will be used to service all of the development, as well as the pump out available
to the marina, and be routed to the wastewater treatment facility. The full design of the
wastewater system will be contingent upon approval for a CAMA Major Permit. Wastewater
design will be permitted after through NC DEQ.
Anticipated Impacts
• Channel & canal excavation disturbances are as follows:
o ±100,440 ft2 (2.3 acres) of shallow open water bottom (PTA & EW AEC's)
o ±65,740.4 ft2 (1.51 acres) of USACE jurisdictional 404-wetlands (includes open water
areas within wetlands)
o ±31,617.7 ft2 (0.73 acres) of highground area (includes ±4,500 ft2 of Albemarle Sound
ES AEC)
o Excavation will result in the removal of±29,317 cubic yards of material below NWL and
±12,881 cubic yards of high ground area (calculated in Autocad). Spoils will consist of
sand, clay, peat and muck.
o It is anticipated that the dredge spoil disposal areas are adequate.
o Turbidity is expected to occur as a result of the excavation; however, the applicant has
indicated that a "plug" will remain in place between the Albemarle Sound and the
canal/basin until NTU's have reached an acceptable level. The applicant has also
indicated that sediment curtains will be utilized as necessary in the Albemarle Sound to
ensure turbidity remains below acceptable levels.
Basin reshaping and filling impacts (prior to connection with the Albemarle Sound):
o Reshaping of the basin will result in ±43,560 ft2 (±1 acre) of basin fill (creating
highground) within the nearshore areas.
o ±435,600 ft2 (10 acres) of bottom fill to achieve -7' to -8' water depth
o Reshaping and filling of the basin will result in the placement of ±65,000 cubic yards of
spoils from canal excavation or from an approved upland sand mine.

Use and Daily Operations of the Project When Complete
Proposed Development Purpose:
The purpose of the proposed project is to develop a resort marina community providing deep water access to the Albemarle Sound
and Atlantic Intracoastal Waterway (AIW) from the west side of Currituck County. Currituck County does not currently have a resort

waterfront development with deep water access suitable for sailboats and larger vessels using the AN on the Albemarle Sound.
Daily operations will be consistent with a marina resort community.
Buildings/Facilities/Units/Structures:
Construction of a marina resort community, with restaurant and light commercial. Proposed 60 feet wide -8.0 ft (NWL) deep
channel, starting at connecting natural water depths of -8.0 in the Albemarle sound and cut through Phragmites wetlands to a depth
of -8.0 ft to connect the existing pond to the Albemarle Sound. A docking facility with fueling stations and pump outs are proposed
within the existing basin to accommodate both the proposed development and transient marina patrons. A boat ramp is also
proposed. Up to 160 wet slips; 6 transient slips and all associated infrastructure. See project narrative for additional detail.
Use & Daily Operations:
A marina resort community with retail and restaurant.
Construction Methodology & Equipment:
Dredging will be by mechanical methods and performed by excavators on barges that will load material onto scows that are also on
barges which will be located behind (pond side) the excavator. Excavator's will load scows that would be pushed by boat into the
pond and the material would then be emplaced around the basin to achieve the proposed water depths (-8 ft.) as presented in the
flushing model. The uplands "neck" will be excavated first starting from the pond side and the operation will continue west into the
proposed canal through the wetlands. A plug (approx. 40-50 feet in thickness) will be left separating the canal and basin from the
Albemarle Sound. The contractor will stop all excavation of the uplands and the canal for a period of approximately two weeks to
allow for settling of any fine materials. Turbidity measurements would be taken to ensure that water quality has stabilized prior to
making any connection to the Albemarle Sound. Additional basin shaping may occur during this time. Once the water quality in the
basin and canal have stabilized (turbidity < 10 NTUs or as required) the "plug" would be removed and the channel and basin would
be connected to the Albemarle Sound. It is estimated that approximately 500-1,000 cubic yards of material can be dredged and
placed into the pond in one working day. Total dredge time is projected to take about three months. Sediment curtains would be
used as necessary to ensure that turbidity in the Albemarle Sound does not exceed any established NTU requirements (<10 NTU's).

No one was signed up nor wished to speak at Public Comment.
COMMISSIONER'S REPORT
Chairman White announced an upcoming meeting on Currituck County Airport facility
operations and projects. Assistant County Manager, Ben Stikeleather, will attend to provide
information and answer questions from airport stakeholders. Chairman White said two House
Bills recently introduced in the legislature by State House Representative Bobby Hanig would
address isolated schools and school transportation, and would likely provide financial relief to
the county school system.
Commissioner Mary Etheridge encouraged people to visit the Historic Jarvisburg Colored
School museum in celebration of Black History Month, as it is open to the public and depicts
a history of rural life in Currituck County.
Commissioner McCord offered condolences to the Walker family on the recent loss of their
son, and thanked the hundreds who attended the services for their support.
Commissioner J. Owen Etheridge recalled earlier discussion at the January Board retreat
and asked that a local bill be submitted to the legislature to allow county access to provide
maintenance and clearing for ditches and waterways.

throughout the development
Plan Request: Decrease the number of dwelling units/density, canal realignment, reduce wetland fill, and
reorient types of dwelling units to improve transition from this development to Kilmarlic Subdivision single-
family dwelling lots.
STAFF ANALYSIS
The Board of Commissioners approved a conditional rezoning request (A to CD-PUD Overlay) in
2008 for this property. The CD-PUD Overlay included 237 mixed residential units, a small
commercial hub, boat marina, public boat ramp, and associated infrastructure improvements. During
the permitting process, the applicant was notified that the proposed waterway connection to the
Albemarle Sound was not a desired alignment by State and Federal agencies. Based on that
feedback, the master plan has been redesigned to reflect a new access to the sound and a new
project layout. Due to the time between the previous approval and the current revised master plan,
wetlands were reassessed with the appropriate State and Federal agencies. Changes to the wetland
boundaries significantly impacted the uplands available for development and required an overall
decrease in the number of units in the previously approved plan.
The proposed amended plan includes a total of 160 mixed residential units with a residential density
of 1.33 dwelling units per acre. The project also has neighborhood serving retail uses, a restaurant,
traditional uses associated with a full -service marina, and associated infrastructure that includes a
small, wastewater treatment plant that serves the project. The development is predicated on a public
access marina, including boat ramp, with a realigned access canal to the Albemarle Sound. The
project is positioned to take boat traffic from the Intracoastal Waterway (ICW) which traverses just
offshore from the proposed project. The marina will provide approximately 208 boat slips for use by
the general public, visitors, and ICW traffic.
The approved master plan included approximately 2.7 acres of wetland fill. Because of the reduction
in density and site redesign, the propose wetland fill impact for upland development is 0.48 acres
which includes filling for road crossings. Wetland fill will be permitted and mitigated through the
appropriate State and Federal agencies. The amended plan also includes a better transition from
Kilmarlic Subdivision by placing the single-family condo style housing units closes to that
neighborhood. Lot 175 within Kilmarlic Club Phase II is the only lot that directly abuts the proposed
planned development. At this location, all buildings have been placed approximately 45 feet from the
residential property line. A minimum 10 feet wide vegetated buffer will be provided along the adjacent
properties zoned residential. All commercial development has been centralized within the community
and will not be adjacent to the existing residential development.
The previously approved plan showed no permanent structures built within 100' of the mean high
water mark. The proposed plan reduces that setback to 30' which matches the UDO 30' required
riparian buffer. The previous plan required waterfront property within 100' of mean high water mark to
remain in common open space. The proposed plan reduces that open space measurement to 30' of
the normal water level. This is consistent with the UDO requirement that riparian buffers remain as
open space.
Community concern has been expressed regarding West Side Lane (SR 1112) being used to access
the development. West Side Lane is an NCDOT maintained road and NCDOT expressed no concern
for the increased traffic on West Side Lane during their review process. Internal pedestrian circulation
will be provided throughout the development and to all commercial areas. Golf cart and bicycle
parking will be provided at the proposed commercial hub to encourage alternative transportation
methods.

Currituck County Board of Commissioners February 18, 2019
following conditions:
1. Staff is concerned with the maneuverability of vehicles pulling boat trailers (turning radius) at
the public boat ramp, lack of vehicle hauling boat trailer parking at the ramp, and the distance
from the ramp to the boat trailer parking lot. (Planning) UPDATE FROM APPLICANT: The
drive aisles within the boat ramp parking lot are currently 32'-35' wide to allow for a boat
maneuvering and access. AutoTURN has been run using a vehicle length of 19' and boat
length of 32' (with an anticipated I V wheelbase). The steering lock angle was assumed at
31.6 degrees. Based on the results of the Auto TURN, simulation areas of the site have been
widened and radii enlarged as necessary. Boat and trailer parking remains proposed
adjacent to the proposed wastewater treatment plant. STAFF NOTE: Staff is satisfied with
the maneuverability of the vehicles pulling boat trailers at the public boat ramp. Staff remains
concerned regarding the distance from the boat ramp to the vehicle/boat parking area
(approximately four -tenths of a mile).
2. A CAMA Major Permit will be required for project development. For permitting assistance,
please contact Ron Renaldi, DCM Field Representative at 252-264-3901. (CAMA) UPDATE
FROM APPLICANT: Acknowledged. A CAMA Major Permit is being prepared and will be
submitted for review prior to the anticipated Board of Commissioners meeting date of
December 3, 2018.
3. Page 3 of the Site Narrative indicates that the proposed subdivision is predicated on a marina
being constructed that offers a connection to the Albemarle Sound, however Page 8 indicates
that permitting for the marina will occur in Phase 2---after 43 units and associated
improvements for those units are installed in Phase 1. It is recommended that permitting for
the marina occur in Phase 1. (CAMA) UPDATE FROM APPLICANT: Acknowledged.

LAND USE PLAN
The 2006 Land Use Plan classifies this site as Full Service and Conservation within the subarea. The
policy emphasis for the Point Harbor subarea is to allow this area to continue to evolve as a full
service community, but with better attention to the planning needed to protect residential areas and
the natural features that make the area so attractive. Vegetative buffers should be
required/maintained along shorelines to preserve public access and open space at the waters edge
and to protect water quality in the sound. The proposed plan is in keeping with the policies of the
plan, some of which are:
Policy HN1
Currituck County shall encourage development to occur at densities appropriate for the
location. LOCATION AND DENSITY FACTORS shall include whether the development is
within an environmentally suitable area, the type and capacity of sewage treatment
available to the site, the adequacy of transportation facilities providing access to the site,
and the proximity of the site to existing and planned urban services.
Policy PA1
Public access to the sound and ocean waters of Currituck County is essential to the
quality of life of residents and visitors, as well as the economy of the area. The County
supports the establishment of ADDITIONAL PUBLIC AND PRIVATE ACCESS
opportunities to the waters of Currituck County.
Policy PA5
PUBLIC AND PRIVATE MARINAS offering access to area waters should be encouraged
when developed in accordance with the CAMA specific use standards for marinas (i.e.
docks for more than 10 vessels). Marinas shall not be approved, however, that are
incompatible with nearby land uses or whose designs fail to meet the environmental
quality and development standards of the County's Unified Development Ordinance.
Policy CD8
MIXED -USE DEVELOPMENTS, properly planned from the outset, which allow for a
compatible mixture of residential and non-residential uses with a pedestrian scale and
Final Minutes Updated 31512019 11:40 AM

Currituck County Board of Commissioners February 18, 2019
design, are encouraged.
Policy
Currituck County supports the retention or preservation of VEGETATED BUFFERS along
WQ6
the edge of drainage ways, streams and other components of the estuarine system as an
effective, low cost means of protecting water quality.
Policy ML3
The interests of Mainland Area residents in having ACCESS TO THE AREA'S OCEAN
AND ESTUARINE WATERS shall be fostered through County actions to increase the
number of additional public access sites at a rate commensurate with the population
growth of the Currituck County. Included in the actions taken to increase public access
shall be a consideration given to transportation needs, including boat docks and ferry
services.
Policy ES2
NON -COASTAL WETLANDS, including FRESHWATER SWAMPS, AND INLAND, NON -
TIDAL WETLANDS, shall be conserved for the important role they play in absorbing
floodwaters, filtering pollutants from stormwater runoff, recharging the ground water table,
and providing critical habitat for many plant and animal species.
Policy
Development that preserves the NATURAL FEATURES OF THE SITE, including existing
WQ5
topography and significant existing vegetation, shall be encouraged. COASTAL AND
NON -COASTAL WETLANDS shall not be considered part of a lot's acreage for the
purpose of determining minimum lot size or development density.
CONSISTENCY AND COMPATIBILITY STATEMENT

PLANNING BOARD MEETING 12/11/2018
Final Minutes Updated 31512019 11:40 AM

Currituck County Board of Commissioners February 18, 2019
RESULT: RECOMMENDED APPROVAL WITH PLANNING BOARD RECOMMENDED CHANGES
[UNANIMOUS]
AYES: Anamarie Hilgendorf, Board Member, Fred Whiteman, Chairman, C. Shay Ballance, Vice
Chairman, Steven Craddock, Board Member, Jane Overstreet, Board Member
ABSENT: Carol Bell, Board Member, Joanne M. DiBello, Board Member, J. Timothy Thomas, Board
Member
MOTION: Mr. Craddock motioned to approve PB 08-48 Cape Currituck for the conditional rezoning
with the agreed upon conditions since total number of dwellings has reduced with no more than 30
residential dwelling units shall receive a certificate of occupancy prior to the public marina being fully
permitted and approved by any local, state, and federal regulatory or permitting agency, no more than
60 residential dwelling units shall receive a certificate of occupancy prior to the marina being fully
operational and open to the public and no more than 100 residential dwelling units shall receive a
certificate of occupancy prior to the commercial components of the request being approved and fully
constructed. Also, to include the pedestrian walkway between the parking and the boat ramp with
additional signage to prevent pedestrian danger.
Ms. Overstreet seconded the motion and the motion carried unanimously.
PLANNING BOARD DISCUSSION 12/11/2018: Senior Planner, Tammy Glave presented the staff
report. Ms. Glave said staff is recommending approval. The number of dwelling units will be reduced
from 237 to 160 which will reduce the density. The applicants are putting in extra buffers that are not
required. All the conditions of approval remain the same except two are changing - Ms. Glave
referenced the conditions in the staff report for the changes being underlined (below).
Landscaping/Screening
1. All inland, non -tidal and coastal wetlands not proposed to be filled shall remain undisturbed in
accordance with the Currituck Marina Conceptual Plan. Delineated CAMA, 404, and 401 wetlands
shall be placed in a conservation easement or preservation trust preventing individual ownership or
development.
2. There shall be no development, land disturbing (other than excavation of access
channel, restoration or enhancement of natural ecosystems and management
of invasive species), or logging activities in areas designated by the 2006 Land Use Plan as
Conservation in accordance with the Currituck Marina Conceptual Plan.
This shall not preclude elevated walkways, utilities, or other necessary public improvements.
Ms. Glave said one of staffs concerns was the parking area being a long distance from the boat
ramp. Staff would like a walking path from this area with signs for pedestrian safety.
Mr. Craddock asked if there was adequate space for turning in this parking area and Ms.
Glave said yes, the applicant has run software to show this is adequate.
Cathleen Saunders with Quible & Associates came before the board to represent the applicant. She
said they are reducing the units to 160 and making the design more environmentally friendly with a 30
foot buffer and 42 acre environmental area. Wet pavers will be used to address wet areas. At the
community meeting the key concerns was the use of West Side Lane as an entrance and she said
they have to use this because of the wetlands. NCDOT was onsite and they are in agreement that
using this road as the entrance is compliant with their standards. The boat ramp was not something
that we wanted, but was a requirement made by the Board of Commissioners. The wastewater area
was flipped with the parking area so it would be farther away from the adjourning properties. As far as
the distance of the parking area from the boat ramp, shuttles have been considered.
Chairman Whiteman asked for if there were any persons wishing to speak in opposition.
Tom Voorhees of Duncans Way, Powells Point, said he is the Kilmarlic board representative and they
are concerned about the amount of traffic for West Side Lane. He said there are no lights or

sidewalks and this causes safety concerns for people walking in the neighborhood.
Warren Eadus with Quible & Associates gave their rebuttal. He said they have spoken with NCDOT
about having speed bumps put on the road and this is not favorable due to emergency services
having to have a quick access if needed.
Ray Bruce, a Kilmarlic resident, spoke in opposition. He said he is concerned with flooding and
evacuation of his property if needed.
Mr. Eadus said they have addressed the flooding concerns and there will be a softened shoreline and
elevated homes.
Mr. Craddock asked if West Side Lane was a state maintained road and Ms. Glave said yes. Mr.
Craddock said since it is a state maintained road, shouldn't the residents be taking up their concerns
with NCDOT and Ms. Glave affirmed his statement.
More discussion was held concerning the distance of the boat ramp and parking area. Ms. Hilgendorf
was in favor of an ADA compliant walkway between the two areas. Mr. Craddock asked if the
applicant will agree to walkways and signage. Mr. Eadus said they are willing to do a walkway.

to amend the Conditional District Planned Unit Development (CD-PUD) originally approved
by the Board of Commissioners in 2008. Using the overhead, Ms. LoCicero displayed maps
of the project location and the original approved layout. She reviewed the conditions set at
that time, presented the amendments to the original plan, and displayed a comparison chart
with both the old and new proposal. Conditions and phases for construction included in the
current plan were presented. Ms. LoCicero said both the Technical Review Committee and
Planning Board recommended approval. Planning Board modifications were presented,
as were counter -recommendations made by the applicant.
Construction design elevations were displayed and Ms. LoCicero responded to several
questions posed by Commissioners. She said the applicant is still in the process of
working to find the best canal design for approval of final permits and confirmed Phase I
building could take place prior to receipt of final permits for marina construction.
Warren Eadus, Engineer for Quible and Associates, spoke on behalf of the owners and
developers of Cape Currituck. He said they are still moving through the process for
permitting through the Army Corps of Engineers and Coastal Management. Mr. Eadus
said they want to build the marina, and they are asking to reduce what has already been
approved, lessening the project's environmental impact and bringing it up to today's
standards in the Unified Development Ordinance.
Mr. Eadus responded to questions from the Board, discussed the challenges with the
project, and presented a 2 month timeline for submittal of permitting applications
followed by an estimated 120-150 for approvals.
Developer, Timothy Morrison, spoke on behalf of the project. He began with the
project's history and said the economy in 2008 didn't support it. Mr. Morrison said initial
sale of homes could not be advertised as a marina. He talked of the recent scoping
meetings with the various permitting agencies. Mr. Morrison, when asked, said he
would be agreeable to securing necessary federal and state permits prior to the start of
construction if it means Board approval.
Chairman White called for a brief recess at 7.01 PM. The meeting was reconvened at
7.07 PM.
Chairman White opened the Public Hearing.
Property owner, Denny Horgan, spoke in favor of the project. He described the layout of
the property he has owned for 19 years. He said the project would be good for the
county, and there is no other place on the Albemarle Sound where this project could be
done. Mr. Morrison returned and said presently, there is the ability to launch boats from
the property.
No one else was signed up nor wished to speak. Chairman White closed the Public
Hearing.

Cape Currituck Hydrodynamic and Water Quality Model
Final Modeling Report
April 30, 2019
1. INTRODUCTION
The Cape Currituck Hydrodynamic and Water Quality Model (also referred to as model or
flushing model) was developed as a tool to assist with the evaluation of the water quality
impacts associated with the creation of a proposed marina (Cape Currituck Marina) by
connection of an existing on -site pond to the Albemarle Sound. The project is located in
Currituck County at an approximate latitude and longitude of N36.11796 and W75.85303,
respectively. The developer proposes to dredge a channel 8.0 feet deep (-8.0 feet relative to
Normal Water Level (NWL)) by 60 feet wide that will connect the existing on -site pond to the
Albemarle Sound, while utilizing dredge material to increase the bottom elevation of the basin
so that the basin depth does not exceed the depth of the connecting waters. The proposed
marina development includes residential and commercial uses.
The existing bathymetry of the existing pond and the Albemarle Sound is illustrated Figure 1.
Figure 2 illustrates the proposed bathymetry of the proposed marina and the associated
connecting channel to the Albemarle Sound. The bathymetry illustrated in Figure 2 was used in
the creation of the flushing model. It is important to note that the flushing model was originally
created with a channel alignment that connected at the southern end of the existing pond. In an
effort to mitigate wetland impacts, the currently modeled channel alignment was selected. The
originally modeled channel alignment and the currently modeled channel alignment are
illustrated in Figure 3.
The flushing model was developed to provide answers to the following questions, as outlined in
the original Modeling Plan:
- How will the dissolved oxygen (DO) levels in the Albemarle Sound be impacted by
the creation of the proposed marina and its connection to the Albemarle Sound?
- What is the expected residence time for water within the proposed marina?
- What will be the dissolved oxygen (DO) levels in the proposed marina?
The primary objective of the flushing model was to create a prediction of the proposed water
quality impacts, so that a regulatory decision may be made utilizing quantitative results. The
key water quality parameter of concern was dissolved oxygen. In addition to dissolved oxygen,
focus was placed on residence time/age of water, due to the correlation between residence time
and water quality impacts.
2. MONITORING
Monitoring efforts throughout development of the Cape Currituck Hydrodynamic and Water
Quality Model facilitated the provision of data required for the creation of the input files
necessary to build the hydrodynamic and water quality modeling capabilities of the flushing
model.
Four water quality stations were designated as sampling points for collecting data on pH,
conductivity, turbidity, dissolved oxygen, temperature, and salinity. Two stations were
designated within the Albemarle Sound (WQ-1 and WQ-2), and two stations were designated
within the existing pond (WQ-3 and WQ-4). During sampling, a fifth water quality station was
designated, WQ-1A, in order to collect water quality measurements to a depth of 8.0 feet.
Water quality data from stations WQ-1 and WQ-1A were used to define the time series data files
at the open boundary condition.

Four Vibracore sampling locations were designated as sampling points to collect sediment core
data to determine the lithology that would be encountered in the channel and canal. Grain size
distributions from the surface sediment obtained during Vibracore sampling were used in the
creation of the sediment transport sub -model.
An on -site weather station, including an anemometer, was used to collect on -site wind data to
be used as a time series data file in the flushing model.
An on -site tidal gauge (pressure transducer) was used to collect water surface data in the
Albemarle Sound, which became the time series data file defining the open boundary condition
in the flushing model.
Locations of water quality sampling stations, Vibracore sampling locations, the on -site weather
station, and the on -site tidal gauge, are illustrated in Figure 3. It is important to note that these
locations were designated during the original phases of model development, in which the
original channel alignment was being modeled. During model development, the channel
alignment was revised, as is also illustrated in Figure 3. Additional information on data
collection and monitoring is provided in the Data Collection Technical Memorandum in Appendix
A, and also in the previously submitted monitoring plan entitled, "Basin Flushing Model: Data
Collection Plan, Cape Currituck, North River/Albemarle Sound", dated May 30, 2018, as
prepared by Quible & Associates, P.C.
3. MODELING APPROACH
The modeling software selected for the flushing model was the Environmental Fluid Dynamics
Code (EFDC). The features and capabilities of EFDC allowed for the system to be modeled
from a hydrodynamic and a water quality standpoint and provided for the creation of a three-
dimensional model with multiple vertical layers. EFDC also supported the creation of the
sediment transport sub -model. Specifically, EE Modeling System, consisting of
EFDC_Explorer, EFDC+, and CVLGrid, was selected based on the availability of the graphical
user interface for pre- and post -processing. CVLGrid was used for grid generation, in an effort
to develop a grid best representing the model domain. Figure 4 represents the Cape Currituck
Hydrodynamic and Water Quality Model Framework.
The three-dimensional flushing model domain consists of a grid containing 7,296 cells and four
vertical layers. A three-dimensional surface was created in AutoCAD Civil3D to represent the
proposed bathymetry of the marina and the associated channel. The bathymetric data points
from the proposed surface, along with the existing bathymetric data points from the Albemarle
Sound were imported into the flushing model to create the bottom elevations of the model. In
order to simulate the proposed jetties where the proposed channel meets the shoreline, two
rows of cells (one on each side of the channel) were deactivated, representing the physical
barrier created by the jetties. Figure 5 illustrates the model grid with bottom elevations
represented.

Time series data files were created for salinity, temperature, dissolved oxygen, wind (two
stations), and water surface elevation. Initial conditions were set in the model for salinity,
temperature, dissolved oxygen, and water surface elevation.
The open boundary condition in the flushing model includes the westward facing cells. The
open boundary condition was assigned the time series data file of water surface elevations to
serve as the pressure series. Time series data files for salinity, temperature, and dissolved
oxygen were attached to the open boundary condition to allow for these parameters to change
over time according to the water quality data measurements that were collected in the field. It is
important to note that, due to the location of the site, the proposed marina would be minimally
influenced by astronomical tidal forces; and therefore, a harmonic time series was not
applicable to the open boundary condition. The hydrodynamics in the model are driven by the
water surface elevation time series and the time series for wind at each of the two wind stations.
Four withdrawal/return boundary conditions were activated within the model, representing
proposed pumping from the marina to the open water, which is discussed in greater detail in
Section 7, Model Results and Section 8, Scenario Analysis.

Initial Conditions were established for water surface elevation, salinity, temperature, and
dissolved oxygen, as illustrated in the Model Framework. Sediment Oxygen Demand was
established at a constant rate of -1.5 g/m2/day across all cells within the active model domain.
The dye constituent was activated in the model in two different capacities. During the full
hydrodynamic and water quality model run, the dye constituent was used to represent the age
of water. During the conservative tracer run, the dye constituent was used to represent the
flushing of a conservative tracer that was introduced to all cells within the proposed marina at
each of the four vertical layers at a concentration of 100 mg/L.
Particle Tracking was activated within the model to demonstrate the motion of particles placed
within the marina to further identify hydrodynamic impacts within the marina.
The model timing begins on June 29, 2018 and ends on September 24, 2018. The model
operates based on Julian dates, and therefore, a base date of June 29, 2018 was used as
Julian day 0. All data was processed by converting to Julian dates representing number of days
since the base date of June 29, 2018 (Julian day 0). The model timing was selected to simulate
"worst -case" conditions for dissolved oxygen and flushing time for the proposed marina. The
selected timing provided for data collection during periods of time where dissolved oxygen

levels are low due to high water temperatures, and the prevailing wind direction is from the
south, southwest, and west, resulting in the "stacking" of water within the proposed marina, thus
reducing the flushing capacity of the marina.
The sediment transport sub -model was built by activating non -cohesive sediments and defining
a sediment bed layer consisting of a fine-grained sand. Particle size distribution reports
(provided in Appendix C) were generated from samples of the top layer of the sediment bed,
obtained from the Vibracore sampling. Grain size parameters were used to build the sediment
bed, along with additional parameters computed by the software, using Van Rijn equations.
Additional information on the modeling approach is provided in the Initial Model Setup Technical
Memorandum in Appendix A.
4. MODEL INPUT
Input data used in the flushing model consists of water surface elevation data, wind data, water
quality data, and non -cohesive sediment data. Spreadsheets containing data used in the
project, including water surface elevation data, on -site anemometer data, Dare County Regional
Station data, and water quality data are included in Appendix B. Due to the amount of data
used in the model, only the first page of data for water surface elevation and wind data were
provided in Appendix B. Spreadsheets containing the comprehensive lists of data are included
in the electronic files associated with the electronic project submittal. The water quality data
contained in Appendix B contains the data from Water Quality Stations WQ-1 and WQ-1A,
which was used to define the time series for each parameter at the open boundary condition.
For spreadsheets containing the water quality data for all Water Quality Stations (WQ-1, WQ-
1A, WQ-2, WQ-3, and WQ-4), refer to the Data Collection Technical Memorandum in Appendix
A.
Data processing for all input data required the conversion of dates and times to Julian days, with
a base date of June 29, 2018 (Julian day 0). All data in the model is in metric units.
Water surface elevation data was used to define the open boundary condition in the flushing
model. The data was processed by converting recorded sensor depths to water surface
elevations in feet, which were then converted to water surface elevations in meters. An initial
sensor depth was recorded as -1.22 feet, thus, water surface elevations were calculated by
adding the depth of water above the sensor to the initial sensor depth. A correction was made
to the sensor depth each time the data was recorded. Each time the data was recorded, the
pressure transducer was pulled from the PVC riser, and when returned to the PVC riser, it
returned to a bottom elevation that had changed from the original bottom elevation, due to
sedimentation. The depth reading after returning the pressure transducer to the PVC riser was
subtracted from the depth reading before removing the pressure transducer from the PVC riser,
and the difference was added to the sensor depth for calculation of subsequent water surface
elevations. Details on this correction to the data are provided in Appendix B. Water surface
elevation data was input from Julian day 0.526 to Julian day 87.532.
Wind data was used to define time series data for the Cape Currituck on -site anemometer and
for the Dare County Regional Station. The on -site anemometer provided data from Julian day
18.411 to Julian day 68.448 (the on -site weather station was removed from the site in advance
of Hurricane Florence). Wind direction was converted from "direction from" to "direction toward",
measuring clockwise from North, with North representing 0°. For example, a wind blowing from

Cape Currituck Hydrodynamic and Water Quality Model

East to West would be represented by a direction toward 270° in the model. Wind speed was
converted from miles per hour to meters per second. After reviewing the wind direction data
from the on -site anemometer and comparing it to the wind direction data from the Dare County
Regional Station, a correction of 45° counter -clockwise was applied to all wind direction
measurements. This allowed for the on -site anemometer wind rose to more closely resemble
the Dare County Regional Station wind rose.
Dare County Regional Station wind data was obtained from Weather Underground at
https://www.wunderground.com. Wind data for this station was input into the model from Julian
day 0.010 to Julian day 87.986. Wind direction was downloaded in the form of cardinal
directions and subdivisions of cardinal directions, which were converted to direction in degrees
(for example, wind from the southwest would be represented by a direction from 225°).
"Direction from" was then converted to "direction toward", and wind speeds were converted from
miles per hour to meters per second.
Time series data files for salinity, temperature, and dissolved oxygen were created from the
weekly monitoring data for water quality stations WQ-1 and WQ-1A. These two stations were
used to define the time series data files, because these stations were nearest the open
boundary condition, and the time series data files were attached to the open boundary condition
when input into the model. The time series data files for salinity, temperature, and dissolved
oxygen were input from Julian day 0.526 to Julian day 89.526. The time of day assigned to the
water quality measurements was 12:37:16 to allow for an initial date consistent with the model
start time of Julian day 0.526 (actual time of day for water quality measurements varied, but
measurements were primarily collected from morning through the middle of the day). Each
parameter of data was collected at depth intervals of one foot; and because the model consists
of four vertical layers, the depth measurements were partitioned into the corresponding vertical
layers. Multiple parameter values for each layer were averaged to allow for the assignment of
one value in each of the four vertical layers for each parameter at each collection time. Prior to
water quality station WQ-1A being added to reach a depth of 8.0 feet, data points stopping at
5.0 feet of depth were extrapolated to reach 8.0 feet of depth. There were also instances where
the measurements from water quality station WQ-1 were used for the first 5.0 feet of depth,
while measurements from water quality station WQ-1A were used for depths greater than 5.0
feet, based on available data. When a full range of data was available at water quality station
WQ-1A, these data sets were used over the data available at water quality station WQ-1.
Detailed tables illustrating the available data are provided in Appendix B.
Bathymetric data in the model consists of measured bathymetric data in the Albemarle Sound,
data created from a proposed three-dimensional surface simulating the proposed marina
bathymetry and the proposed channel, and bathymetric data created by the modeling software
through interpolation of empty grid cells. The extents of the surveyed bathymetric data in the
Albemarle Sound did not encompass the entire model domain, and thus, the modeling software
interpolated bottom elevation values outside of the surveyed area.
Following Hurricane Florence, water quality station WQ-1A exhibited low dissolved oxygen
levels at depths of 7.0 feet and 8.0 feet, and high salinity values at depths of 6.0 feet, 7.0 feet,
and 8.0 feet. The abnormal values for dissolved oxygen at depths 7.0 feet and 8.0 feet were
discarded from the input data and were replaced with the dissolved oxygen value recorded at a
depth of 6.0 feet. The abnormal values for salinity at depths 6.0 feet, 7.0 feet, and 8.0 feet were
discarded from the input data and were replaced with the salinity value recorded at a depth of 5
feet.

Final Modeling Report
For the sediment transport sub -model, sieve analysis results from the top layer of fine-grained
sand samples, obtained during Vibracore sampling, were used to define median grain size
diameters for the non -cohesive sediment bed layer. Two samples were obtained from the
Albemarle Sound, and the median, D5o, grain sizes for each sample were averaged for input into
the model. An initial condition for bed mass was assumed to be 10,000 g/m2/layer, and an initial
condition for water column concentration was assumed to be 0 mg/L. The sediment layer
thickness was assumed to be 0.152 meters. The sediment transport sub -model was created
based on the objective of modeling the transport of 6-inches (0.152 m) of a fine-grained sand
across the entire model domain. Additional sediment was not introduced in the water column at
the open boundary, as the premise of the sediment transport sub -model was to investigate
potential impacts of the non -cohesive sediment in the sediment bed, and not suspended
sediment or cohesive sediments.
Additional information on data processing is provided in the Data Processing Technical
Memorandum in Appendix A.
5. CALIBRATION AND CORROBORATION
Due to the nature of the Cape Currituck Hydrodynamic and Water Quality Model representing a
proposed system, traditional calibration and corroboration methods were not applicable. The
existing pond is currently disconnected from the Albemarle Sound, and therefore, sampling
procedures of the current environment could not be used to validate predicted model results.
Data obtained from the water quality sampling stations within the existing pond (WQ-3 and WQ-
4) were used to determine baseline water quality parameter levels that exist in the current pond;
and these data were not used as model input parameters.
6. WATER QUALITY PARAMETER OBJECTIVES
Water quality parameter objectives were researched to align with supporting answers to the
essential questions proposed to be answered by the flushing model. Water quality parameters
investigated in the model include residence time, or flushing time, within the marina, which
translates to the ability of the marina to flush a contaminant in the form of a conservative tracer,
and dissolved oxygen. Research referenced during the analysis of the flushing model may be
summarized as follows:
The USEPA, in their Coastal Marina Assessment Handbook, reference that "a flushing turnover
rate of two to four days has been recommended" (USEPA, 1985, p. 4-83).
The NCDENR, in their Guidelines for Planning an Upland Marina Development, reference that
"EPA recommendations are a flushing reduction of 85%-90% in a 24-hour period" (NCDENR,
2011, p. 15).
The NCDENR, in their Guidelines for Planning an Upland Marina Development, reference that
"DO shall be `not less than 5.0 mg/L... "' (NCDENR, 2011, p. 14).
7. MODEL RESULTS
Due to location of the site, the proposed marina would be minimally influenced by astronomical
tidal forces. The dominating hydrodynamic force affecting flushing time is wind -driven tidal
influence. During the temporal scope of the model, the prevailing wind direction is from the

south, southwest, and west, creating a "stacking" effect of water within the marina, which
translated to undesirable values for residence time, or flushing time, within the marina. To
improve flushing time, and associated dissolved oxygen concentrations, four pumps were
introduced into the marina by activating a withdrawal/return boundary condition in four locations.
Two cells at the north end of the marina and two cells at the south end of the marina were
activated as withdrawal cells, withdrawing a constant rate of 1,250 gallons per minute
(0.0788625 m3/sec) at each location, and returning at an identical rate to four cells located on
the south side of the southern jetty.
After a full -duration model run of 87 days, average residence time (water age) values were
predicted along the range of approximately 2.75 days to 4.25 days within the marina cells and
within the portion of the channel proposed between the marina and its connection to the
Albemarle Sound at the shoreline. These results indicate results that are in reasonable
agreement with the suggested two to four day flushing time recommendation in the USEPA
Coastal Marina Assessment Handbook (USEPA, 1985, p. 4-83). Figures 7, 8, 9, and 10
illustrate the depth -averaged (across all four vertical layers) values for age of water at time
values of one week, 30 days, 60 days, and 87 days since model start time, respectively. Figure
15 displays a graph of the average water age within the marina and the portion of the channel
described above with respect to time.
After a full -duration model run of 87 days, average dissolved oxygen values predicted to remain
greater than 5.75 mg/L in the marina cells and within the portion of the channel proposed
between the marina and its connection to the Albemarle Sound at the shoreline. These results
indicate results that are in reasonable agreement with the requirement that "DO shall be `not
less than 5.0 mg/L... "' provided by the NCDENR in their Guidelines for Planning an Upland
Marina Development (NCDENR, 2011, p. 14). Figures 11, 12, 13, and 14 illustrate the depth -
averaged (across all four vertical layers) values for dissolved oxygen at time values of one
week, 30 days, 60 days, and 87 days since model start time, respectively. Figure 16 displays a
graph of the average dissolved oxygen concentration within the marina and the portion of the
channel described above with respect to time.
To further simulate the marina's ability to be flushed of a given constituent, in the form of a
conservative tracer (no decay rate), a model was run with the introduction of a dye, at a
concentration of 100 mg/L, being injected to each cell of the marina and at each of the four
vertical layers. The model was run for a duration of 30 days, beginning at day 0.526. After
reviewing the results of the 87-day model run, it appears that the longer residence times
occurred during the first ten days of the model duration. Figure 17 illustrates the 100 mg/L
conservative tracer injected into the marina at day 0.526. Figures 18, 19, 20, 21, 22, 23, and
24 illustrate the conservative tracer concentrations (depth averaged) at one day, two days, three
days, one week, ten days, two weeks, and 30 days, respectively. Figure 25 displays a graph of
the average conservative tracer concentration within the marina cells with respect to time.
Results indicate that the conservative tracer concentration in the marina reduces to an average
concentration of 15 mg/L (85% reduction) at a Julian day of approximately 6.2, representing
approximately 5.7 days after the model run began.
Sediment Transport Sub -Model:
The sediment transport sub -model indicated results suggesting greater channel stability nearer
the shore, with relatively minor amounts of sedimentation occurring in the channel during a
model run time of 70 days. The results during the first 70 days were considered, because at

Julian day 68, the on -site weather station was removed due to the forecasted path of Hurricane
Florence. It is reasonable to assume that the model validity for sediment transport was
increased during the duration of the on -site weather station data file. Figures 26, 27, 28, and
29 illustrate the morphology of the sediment bed, and corresponding bottom elevations, along
row j = 106 (row of cells along the channel alignment from the open boundary condition to the
terminal point within the marina) at Julian day 0.526, day 30.526, day 60.526, and day 70.005,
respectively. It is important to note that the bottom elevation of grid cell 13i, 106j, located near
the western end of the proposed channel, changes in bottom elevation from -2.286 meters (-
7.50 feet) at Julian day 0.526 to -2.189 meters (-7.18 feet) at Julian day 70.005, with 0.08
meters (0.26 feet) of that increase occurring during the first 30 days of the model run. Between
Julian day 30.526 and Julian day 70.005, the bottom elevation of this grid cell increases by 0.02
meters (0.06 feet).
8. SCENARIO ANLAYSIS
During model development, scenario analyses were conducted to improve residence time (age
of water) within the marina, and to also improve dissolved oxygen concentrations. Prevailing
wind directions during the summer months, in combination with the proposed channel alignment
and the lack of a significant astronomical tidal impact, caused for lengthened residence times,
and subsequently, poor dissolved oxygen concentrations. It is anticipated that prevailing wind
directions during fall and winter months would improve flushing times; however, winter months
were not included in the temporal scope of the model. To improve flushing time, pumps were
introduced to four locations within the marina, with discharge locations on the south side of the
entrance channel. Pumping rates were varied until flushing times and dissolved oxygen
concentrations were improved to appropriate values within the marina and access channel.
9. MODEL LIMITATIONS AND KEY ASSUMPTIONS
During data collection and sampling, it was observed that water quality samples obtained from
sampling locations within the existing pond (WQ-3 and WQ-4) exhibited high levels of dissolved
oxygen. While these water quality parameter values were not used in the flushing model, it is
important to note that there exist hydrologic and geologic features (e.g. groundwater recharge)
lending to the favorable water quality within the existing pond. Additional data would be
required to begin a modeling approach directed at simulating the existing hydrologic and
geographic features promoting the water quality observed in the pond. Without modeling these
features, the flushing model may represent a more conservative approach to predicting the
water quality impacts associated with the connection of the existing pond to the Albemarle
Sound.
The sediment transport sub -model represents an approach to sediment transport in which the
sediment bed is composed of non -cohesive sediment, with cohesive sediments not being
considered in the model. Further analysis and research regarding sediment transport in this
area could produce varying results pertaining to sediment transport and rates of sediment
accumulation within the proposed channel. These model limitations should be considered when
analyzing the results of the hydrodynamic and water quality model, and the sediment transport
sub -model.

Cape Currituck Hydrodynamic and Water Quality Model April 30, 2019
Final Modeling Report
10. SUMMARY
The Cape Currituck Hydrodynamic and Water Quality Model provides answers to the essential
questions outlined in the original Modeling Plan. Understanding the model limitations and key
assumptions, it is reasonable to assume that the residence time within the proposed marina and
the portion of the channel proposed between the marina and its connection to the Albemarle
Sound would range between 2.75 days to 4.25 days, with dissolved oxygen levels consistently
exceeding the minimum requirement of 5.0 mg/L during worst -case scenario conditions for
hydrodynamics and water quality. While the site, and its geographic limitations impacting
channel length and alignment, provide for undesirable flushing times and dissolved oxygen
concentrations, the introduction of pumping from within the marina to the Albemarle Sound has
provided more favorable results in more substantial agreement with parameter values obtained
from guidance documentation relating to flushing turnover rates and dissolved oxygen levels;
and an 85% reduction of a conservative tracer in approximately 5.7 days appears to be a
reasonable result when considering that the conservative tracer was injected across every cell
in the marina and at every vertical layer at a concentration of 100 mg/L.
Sediment Transport Sub -Model:
The Cape Currituck Sediment Transport Sub -Model provides answers to questions relating to
sediment transport, with results indicating that the portions of the channel nearest the shoreline
appear to demonstrate the greatest stability, with minor impact from sediment transport during
the model run. The areas of the channel nearest the deeper connecting waters demonstrate
slightly larger impacts from sedimentation during the model run time that was consistent with the
input of data from the on -site anemometer (approximately 70 days); however, during those 70
days, the rate of sedimentation in this portion of the channel does not appear to be of major
concern. Further analysis and research regarding sediment transport in this area could produce
varying results pertaining to sediment transport and rates of sediment accumulation within the
proposed channel.

Re: Cape Currituck Hydrodynamic Model — Data Collection
PHASE I VIBRACORE
Four Vibracore samples were collected within the channel and canal alignment as shown and
discussed in the May 30, 2018 Basin Flushing Model Data Collection Plan. The purpose of the
core sampling was to understand the lithology that would be encountered in the channel and
canal. The lithology was also used to help understand the volumes of sand that are migrating
along the near shore.
Vibracore samples were collected using a custom Vibracore assembly that includes a Dreyer
concrete vibrator with an 8 hp motor, custom welded bracket for attaching to three-inch
aluminum irrigation pipe and custom aluminum tripod and winch extraction system.
Photo 1. Vibracore setup over VC-3.

CSC
Thin walled aluminum irrigation pipe was advanced into the substrate generally until core
refusal. Once core refusal or desired core depth was achieved, the cores were cut below the
water level and capped. Cores were then extracted using a winch. Once the bottom of the core
was able to be reached, a second cap was installed. Caps were secured with duct tape, cores
were labeled (top and bottom and with the corresponding boring number) and transported back
to Quible for processing. Processing cores involved cutting the aluminum with a ten -inch
circular saw in two linear cuts. The top half of the cut pipe was removed, and the sediment
types were measured, recorded and photographed. Samples of each separate layer were
collected for future reference. Core depths and corresponding lithologies found within each
core are shown on the attached boring logs. A cross section generated from the boring lithology
has also been included for reference.
Photo 2. Core sample split and lithology being measured.

PHASE II
DATA COLLECTION
As discussed in the Basin Flushing Model Data Collection Plan (Plan), sampling stations were
established in locations as shown in the Plan. The location of VC-1/WQ-1 was in water depths of 5-6
feet. Therefore, an additional station WQ-1A was established in deeper water so that water quality
data could be gathered from an area with at least -8.0 of water (proposed dredge depth).
On a weekly basis (day dictated by weather and wind) water quality parameters (salinity,
temperature, pH, turbidity, dissolved oxygen and specific conductivity) were collected at each of the
five stations on one -foot intervals. Stations were established using survey grade GPS and 1.25-inch
PVC pipes were set using a slide hammer. All PVC markers were labeled, and bright yellow and red
tape was wrapped around the exposed sections of pipe to increase visibility. Quible staff used a
small row boat to collect water quality data in the Albemarle and within the basin/pond.
Photo 3. Deploying Horiba U-10.
Spreadsheets that detail the weekly water quality monitoring are included with this Memorandum.
Meteorological files will be included technical memos and the Model Report as required.

A Horiba U-10 Water Quality Checker was used to measure pH, temperature, salinity, turbidity and
specific conductivity. A YSI Pro Optical DO was used to measure dissolved oxygen and temperature
(redundant). Each of the machines were field calibrated immediately prior to use. Calibration notes
will be included in the final Modeling Report. The cords on each of the machines was pre -measured
and taped. Measurements were checked weekly to ensure accuracy. All of the equipment was
cleaned at the conclusion of sample collection activities. Calibration for the Horiba U-10 consists of
submerging the probes in a solution (purchased from Enviro-Equipment) that has predetermined
values. The Horiba has a built-in calibration function that allows all parameters to be calibrated while
the probes are submerged in an Auto Cal Solution. Fresh Auto Cal solution was used for each
calibration event. The YSI ODO was field calibrated following manufacturers recommendations as
presented in the user guide. The probe has a calibration function that measures atmospheric DO
percentage and atmospheric pressure. Once the atmospheric DO and pressure are within the
acceptable tolerances (as printed in the Appendices of the Pro ODO manual) the probe is calibrated,
and the user can opt to accept the calibration, returning the probe to measurement mode.
A dedicated weather station (comprised of Onset anemometer, rain gauge and temperature loggers)
was installed on the shoreline of the project near the proposed location of the channel. In addition,
an Onset® pressure transducer was installed inside a PVC well screen and riser in the near shore of
the project and close to the channel alignment. The pressure transducer was installed in a protected
area where old bald cypress stumps and posts still exist. The pressure transducer was installed just
above the existing substrate within the riser and the PVC well screen was attached to the riser so that
water could enter the pipe, but any wave action would be attenuated.

Re: Cape Currituck Hydrodynamic Model — Data Processing
The Cape Currituck Hydrodynamic Model has been developed utilizing the following sets of
data, each of which are explained further in the text to follow:
• Bathymetric Data
• Water Surface Elevation Data
• Wind Data
• Salinity Data
• Temperature Data
• Water Quality Data
As an initial step in the data processing, the times associated with data collection were
converted to Julian dates with a base date of June 29, 2018 (day 0 in the model). On -site
data was collected prior to June 29, 2018; however, the water surface elevation data file was
used in the open boundary condition, and the associated piezometer began data collection
on June 29, 2018, thus serving as the base date in the model. Currently, the model contains
data from June 29, 2018 through September 5, 2018. Data was collected through
September 26, 2018, and the additional data beyond September 5, 2018 will be introduced
during the model calibration phase.
Bathymetric Data
Bathymetric Data was incorporated into the model by importing a point file consisting of
northing, easting, and bottom elevation data. A surface was generated to represent the
proposed bathymetry of the marina, and the proposed bathymetry of the access channel.
Existing bathymetric data of the sound was used for the bathymetry in the open water (areas
not proposed to be changed from existing conditions). In areas of the model grid where
bathymetric data was not available (open water), the software interpolated the data from the
adjacent cells containing bathymetric data. Please refer to Figure 1 for an illustration of the
bathymetric data in the model.

CAD
Figure 1: Bathymetric Data in the Hydrodynamic Model
Water Surface Elevation Data
The water surface elevation data collected by the on -site piezometer was imported into the
model (with Julian date conversions) and was used as the open boundary condition time
series. The piezometer's depth -to -water -surface measurements were converted to water
surface elevations.
Wind Data
Wind data was collected with an on -site anemometer and was imported into the model as a
time. Wind data for the Dare County Regional Airport was downloaded from
Wunderg round. com and was imported into the model as a time series. It is important to note
that the software is programmed to read the wind directions as direction toward. Please refer
to Figures 2 and 3 for the wind rose for each wind station.

Salinity Data, Temperature Data, and Water Quality Data
Salinity data, temperature data, and water quality data were collected at the various water
quality stations (from the monitoring report) as part of the weekly monitoring. Each parameter
of data was collected at depth intervals of one foot; and because the model consists of four
vertical layers, the depth measurements were partitioned into the corresponding vertical
layers. Multiple parameter values for each layer were averaged to allow for the assignment
of one value in each of the four vertical layers for each parameter at each collection time.
The salinity, temperature, and water quality data that were collected from the stations nearest
the open water boundary were imported into the model as time series and were introduced to
the boundary condition by applying the time series to Boundary Conditions Group Settings for
concentrations. Please note that multiple water quality parameters were measured, and at
this time, dissolved oxygen is the only water quality parameter being simulated. Salinity data,
temperature data, and water quality data collected from the other water quality stations is
proposed to be used during model calibration. Please refer to Figure 4 for an example of the
"Layer Partitioning" method used to assign parameter values for each vertical layer. Please
refer to Figure 5 for an example of the time series data for temperature, salinity, and
dissolved oxygen.

Re: Cape Currituck Hydrodynamic Model — Initial Model Setup
The Cape Currituck Hydrodynamic Model has been initially setup and developed to be able
to provide answers to the primary questions in the modeling plan:
• How will the dissolved oxygen (DO) levels in the Albemarle Sound be impacted
by the creation of the proposed marina and its connection to the Albemarle
Sound?
• What is the expected residence time for water within the proposed marina?
• What will be the dissolved oxygen (DO) levels in the proposed marina?
Please refer to the attachment following this memorandum for Figure 1: Cape Currituck
Model Framework with an overall description of the model components.
Model Domain
Model setup began with the generation of a curvilinear grid using CVLGrid1.1 software (part
of the EE Modeling System developed by Dynamic Solutions International, LLC). The grid
encompasses the proposed marina, the proposed access channel, and the open water of the
Albemarle Sound. The grid used to build the model consists of 7,718 cells with an average
orthogonal deviation of 0.70 (software guidance recommends an average orthogonal
deviation of less than 30).
Once created, the grid was imported into EFDC Explorer to begin building the hydrodynamic
model. The bathymetric data was loaded into the model, consisting of the proposed marina
and access channel bathymetry and the existing open water bathymetry, with interpolation of
bathymetric data for cells located in areas outside of the areas where data was collected. To
transition from a two-dimensional model to a three-dimensional model, four vertical water
layers were created in the model domain. Bottom roughness was then added to the model,
and an initial condition for water surface elevation was set (0.5 ft., 0.152 m NWL). Please
refer to Figure 2 for an illustration of the bathymetric data in the model.

CAD
Figure 2: Bathymetric Data in the Hydrodynamic Model
The timing in the model was set to begin on June 29, 2018, corresponding to the initial date
of the data collection for the water surface elevation time series. All input files for the model
were converted to Julian dates, with June 29, 2018 being the base date (Julian day 0).
Currently, the model contains data from June 29, 2018 through September 5, 2018. Data
was collected through September 26, 2018, and the additional data beyond September 5,
2018 will be introduced during the model calibration phase.
Hydrodynamics
A time series data file for water surface elevation was built in the model from piezometer data
in the open water. This time series data file was then used to define the open boundary
condition. Two time series data files were built representing two wind stations (on -site
anemometer, and Dare County Regional Airport).
Boundary Conditions
The open water boundary condition was defined for the western model boundary, connecting
to the Albemarle Sound. This boundary condition was assigned the water surface elevation
time series file. For the boundary group settings, time series data was used to define the
concentration tables for salinity, temperature, and water quality. Constant concentration
values were not used in association with the open boundary condition. Please refer to Figure

Open Boundary Condition/Pressure Settings displaying the time series files associated with
the open boundary condition.

Initial conditions were set in the model for the initial water surface elevation, the initial salinity,
the initial temperature, and the initial dissolved oxygen concentration. The initial water
surface elevation was set to 0.5 ft (0.152 m) NWL. The initial condition for salinity was set to
0.18 ppt, representing the average of the salinity data collected on June 29, 2018 for all of the
water quality monitoring stations. The initial condition for temperature was set to 30.1 °C,
representing the average of the temperature data collected on June 29, 2018 for all of the
water quality monitoring stations. The initial condition for dissolved oxygen was set to 9.71
mg/L representing the average of the dissolved oxygen data collected on June 29, 2018 for
the water quality monitoring stations located in the open water.
Activated Modules
Salinity and Temperature: Salinity and temperature were activated in the model, which
included the creation of time series data files representing the weekly monitoring data
collected at the water quality stations nearest in proximity to the open water boundary. The
time series data files were then attached to the open boundary condition by way of
concentration tables in the boundary condition group settings. Initial conditions were
assigned for salinity and temperature as explained above.

CSC
Water Quality: Water quality was activated in the model, which included the creation of a
time series data file representing the weekly monitoring data collected at the water quality
stations nearest in proximity to the open water boundary. Dissolved oxygen was the only
parameter simulated in the water quality module, due to the fact that the primary questions in
the modeling plan are based on dissolved oxygen. The time series data file for dissolved
oxygen was attached to the open boundary condition by way of a concentration table in the
boundary condition group settings. The initial condition for dissolved oxygen was assigned
as explained above. Within the water quality module, sediment oxygen demand (SOD) was
activated at a rate of -1.7 g/m2/day.
Dye: Dye/Age was activated in the model to simulate the age of water, translating to the
prediction of residence time of water within the proposed marina.
Lagrangian Particle Transport: Lagrangian Particle Transport was activated in the model as
a way to identify the movement of particles within the marina. This information will be useful
in the calibration phase of model development in the event that calibration may be made
based upon the movement and destination of the particles.
Summary
The Cape Currituck Hydrodynamic Model has been initially built to be able to provide
answers to the primary questions in the modeling plan. The next steps of model
development shall include the import of additional data through September 26, 2018, followed
by model calibration and corroboration. The goal of further model development shall be to
increase model accuracy and its ability to predict the water quality impacts associated with
the creation of the proposed marina and its connection to the Albemarle Sound. Once further
developed, test case scenarios shall be implemented to identify methods to improve upon
residence times and water quality.

Cape Currituck Hydrodynamic and Water Quality Model
Addendum to Final Monitoring Report
June 3, 2019
7A. MODEL RESULTS -NATURAL CONDITIONS
This addendum considers an EFDC model run of 87 days for the proposed Cape Currituck
Marina under natural conditions —post construction (without any mechanical flushing
assistance). The marina basin (created from an existing pond) and channel are analyzed for
average dissolved oxygen and average age of water versus time.
Dissolved oxygen versus time data indicates that the basin and channel maintain an average
dissolved oxygen concentration of at least 5.0 mg/L during the model run of 87 days. Age of
Water or residence time is predicted to peak at about 22.5 days (three weeks) according to the
87-day model run time.
Average residence time (water age) values were predicted along the range of approximately 5
days to 22.5 days within the marina cells and within the portion of the channel proposed
between the marina and its connection to the Albemarle Sound at the shoreline. Figures 7a,
8a, 9a, and 10a illustrate the depth -averaged (across all four vertical layers) values for age of
water at time values of one week, 30 days, 60 days, and 87 days since model start time,
respectively. Figure 15a displays a graph of the average water age within the marina and the
portion of the channel described above with respect to time.
After a full -duration model run of 87 days, average dissolved oxygen values are predicted to
remain above 5.0 mg/L in the marina basin and channel. Figures 11a, 12a, 13a, and 14a
illustrate the depth -averaged (across all four vertical layers) values for dissolved oxygen at time
values of one week, 30 days, 60 days, and 87 days since model start time, respectively. Figure
16a displays a graph of the average dissolved oxygen concentrations within the marina basin
and channel with respect to time.
There are several examples of manmade basins and canals in the Currituck, Roanoke and
Albemarle Sounds that have relatively long residence times (typical in estuaries with
microtidal/wind tide influence) without having a history of poor water quality, fish kills,
eutrophication or other indications of low dissolved oxygen and elevated pollutant
concentrations. Please note, the basin in this model is an existing pond with relatively and
naturally high dissolved oxygen concentrations (average DO across all layers exceeds 7.68
mg/L) as shown in the attached water quality data (previously submitted) reproduced for this
addendum (Addendum Tables 1-5).
Therefore, while hydrodynamic modeling indicates slow flushing times for the basin, it is critical
to recognize that the projected water quality conditions (DO) in the channel, basin and adjacent
waters of the Albemarle are expected to be acceptable with respect to dissolved oxygen (>5.0
mg/L).

INTEROFFICE MEMORANDUM
TO: Anthony Scarbraugh, DWR Washington RO
FROM: Pam Behm, DWR Modeling and Assessment Branch
SUBJECT: Cape Currituck Marina Model Review Comments
DATE: August 21, 2019
The Division of Water Resources (DWR) Modeling and Assessment Branch has completed review of the
Cape Currituck marina model report addendum which is dated June 3, 2019 and the model package
"RUN052819". After several attempts, DWR has been unable to fully run the model, the model predicts
a 12-day runtime and our IT protocols are interrupting the process. DWR was able to complete a partial
model run for 26 days (not 87 days for a full model run), which visually confirmed some of the output
graphs presented in the report (Figure 7a, 11a, 15a and 16a of the report). The Demo version of EFDC
Explorer that is available to DWR has been used to generate graphs in this comment. It has limited
functions processing model output.
We offer the following model review comments:
Dissolved Oxygen (DO):
• NC Coastal Marinas: Water Quality Assessment (Jan 1990) - states "Water column averages
provided the most representative assessment of oxygen conditions in the marinas, particularly
during stratified conditions. Therefore, whole column averages are the focus for the following
discussion."
o Cape Currituck Addendum —Figure 16a shows that DO never gets below 5 mg/L when
the entire marina and channel cells are averaged together.
o However, DWR prepared time series plots on 6 random locations within the marina (but
note they are only for the first 26 days, not the full model run of 87 days) and there are
days when the depth -averaged DO is below 5 mg/L. See the figure provided below.
Flushing:
• Model shows average water age somewhere around 11.5 days (estimating from the scale shown
on Figure 10a and Figure 15a).
• NC Water Quality Guidelines for Planning an Upland Marina Development (DWR, 2011 draft)
notes that "EPA recommendations are a flushing reduction of 85%-90% in a 24 hour period
(EPA, 1985)."
• Guidance Specifying Management Measures for Sources of Nonpoint Pollution In Coastal Waters
(EPA, 1993, Chapter 5 page 12) "However, if the marina was in a protected area, such as an
estuary or embayment, where tidal ranges never attain 1.82 meters, then a minimum flushing
reduction of approximately 85% per day was recommended."

• Coastal Marina Assessment Handbook (EPA, 1985) "For most cases a two to four day flushing
time is satisfactory while longer flushing times may not be acceptable (Boozer, 1979). Evaluation
of the buildup of particular toxic pollutants or the decrease in dissolved oxygen would be
required to better evaluate the adequacy of flushing for enclosed marina sites."
Takeaway:
When the entire marina basin and channel are averaged -together, it appears that DO is protected in
that depth -averaged DO does not go below 5 mg/L. However, depth -averaged time series analysis at
specific locations indicates that there are times when parts of the marina do drop below 5 mg/L.
Flushing looks to be poor and against "recommended" guidelines as noted above.

Subject: Response to Cape Currituck Basin Design Questions and Comments
Mr. Eadus,
The Division of Water Resources (DWR) Washington Regional Operation Section in collaboration with the
Modeling and Assessment Branch have completed the review of the supplemental information provided
by Quible & Associates, P.C. (Quible) on September 17, 2019 in response to the DWR Memorandum dated
August 21, 2019 entitled "Flushing Model Review." DWR would like to take this opportunity to remind
both, your client and Quible that DWR has not received a formal application for the proposed project and
any response or comments provided by DWR are considered part of the pre -application and thus do not
represent a final agency decision.
After completion of the DWR's review, we offer the following comments:
Quible Question 1. Is demonstrating that predicted average DO concentration in the marina basin and
channel do not go below 5 mg/L not sufficient? Quible constructed a conservative model that factors in
a SOD concentration of 1.5 mg/L (typically this value is used in organic soils, sandy soils have published
concentrations closer to 0.4 mg/L) and we have predicted that the average DO for the basin and the
channel is at or above the State Regulatory threshold of 5.0 mg/L. The 1990 Study Conclusions also state
that while there are "significant differences between marina basins and ambient water were observed for
fecal coliforms, chlorophyll a, and dissolved oxygen (DO), by there was no evidence that water quality
conditions inside marinas were exported to adjacent ambient waters."
Answer: In order to better understand the DO variability, a statistical distribution summary of the
percentage of time that vertical -averaged DO concentrations are lower than 5 mg/I from each model cell
within the proposed marina as well as the channel is needed. The channel and marina should be evaluated
separately for this analysis.
DWR does not recommend adjusting the model using a lower SOD value than 1.5 grams 02/m2-day. The
North Carolina Coastal Marinas: Water Quality Assessment (Jan 1990) reported that: "sediment oxygen
demand (SOD) was measured at three marinas. Rates were higher than expected, ranging from 2.60 to
5.36 g 02/m2-day in the marina basin." In addition, based on information provided in a Quible
Memorandum dated January 8, 2019 regarding "Cape Currituck Hydrodynamic Model — Data Collection,"
organic matter was found at the top sediment core for Stations VC-3 and VC-4.

DWR would also further state that within 15A NCAC 02B .0220 Tidal Salt Quality Standards for Class SC
Waters (2) states "The best usage of waters classified as SC shall be maintained as specified in this Rule.
Any source of water pollution that precludes any of these uses on either a short-term or long-term basis
shall be deemed to violate a water quality standard."
Quible Question 2. IS providing a natural conditions model that demonstrates that the average DO in
the basin and channel is at or above 5.0 mg/L is not acceptable, will DWR consider a model run using a
lower SOD concentration from published data for sandy soils?
Answer: Please see above for Answer to Question 1.
Quible Comment 1. In the USEPA Coastal Marina Assessment Handbook, "Environmental Solutions" (5-8)
"Mechanical Devices" In areas where tidal exchanges may not adequately flush the marina, mechanical
means such as tide gates or one-way values may be used to enhance flushing rates. However, the
performance of these systems should be carefully evaluated before installation. Such systems have been
used in Florida to flush canals in dead-end lagoon developments. (Gianno and Wang, 1974)
Response: As referenced in several past meetings between Quible and DWR and/or other resource and
permitting agencies, an alternative analysis will have to be submitted as part of the Individual Permit
application submittal that demonstrates the proposed action is the Least Environmentally Damaging
Practicable Alternative.
Question 3/Comment 2. If providing a natural conditions model that demonstrates that the average DO
for the marina basin and channel is at or above 5.0 mg/L with poor flushing (we acknowledge that a
specific flushing time is not a requirement to meet any specific rule or criteria, however,
recommendations for flushing times that meet EPA and DWR guidance are desired) is not acceptable, will
DWR consider a marina design and operation that employs mechanical flushing? Quible has prepared and
submitted to DWR a flushing model that considers using intakes and pumps to manually enhance the
recognized poor flushing times in the marina basin. Based on our model runs using mechanical pumps,
we can reduce the basin flushing time to four days with predicted DO concentrations that do not go below
5.0 mg/L.
If mechanical pumps are considered we recognize that in order to protect juvenile fish and invertebrate
eggs and larvae, we would need to design pumps and screens that maintain a maximum intake velocity of
0.5 feet per second (or other appropriate velocity as determined after consultation with appropriate
federal and state regulatory agencies) across a 3116' mesh screen that will surround the pump intakes.
This will result in an average velocity of 0.3 feet per second. This low intake velocity will allow juvenile
and adult fish to outswim the flow field. It will also restrict the risks of impingement and entrainment to
egg and larval stages of fin- and shellfish. The greatest need for the use of a mechanical pumping system
will be in the summer (June through September) and/or during periods of minimal wind -driven circulation.
Exact mesh sizes, flow rates, pump times and pumping design can be discussed in greater detail if this
mechanical method is accepted, at least in theory by the regulatory agencies.
Answer and Response: DWR and other resource agencies have historically objected to the use of
mechanical devices to meet established Water Quality Standards, both in the terms of the concern
referenced above and the concern of long term operations and maintenance of the system. In addition,
DWR would like to reiterate that other proposed alternatives will have to be evaluated that may result in
less environmental impacts as part of the application review process.

Re: Proposed Marina at Cape Currituck
Statistical Analysis of Simulated Dissolved Oxygen
Mr. Scarbraugh,
Thank you for the February 13, 2020 response to our questions submitted in writing to the
Division of Water Resources (DWR) on September 17, 2019. The attached statistical analysis
of simulated dissolved oxygen (DO) was prepared by Mr. Chris Reed (AECOM) on behalf of
Cape Currituck.
According to the attached report, ."...20% of the cells have a DO value below 5.0 mqlL 5 to 10%
of the time, or similarly, 80% of the cells have a DO value above 5.0 mc A IL 95% or more of the
time." In addition, the report states "The results for the Inlet Channel indicate very few
occurrences of DO values below 5.0 mqlL".
Based on the attached statistical analysis and our review of the 87-day model run, there is no
evidence that the predicted DO concentrations in the proposed marina would contribute to DO
concentrations below 5.0 mg/L in the Albemarle Sound.
Your attention to this letter and attached statistical analysis is greatly appreciated.
Please do not hesitate to contact the undersigned at 252.491.8147 or via email at
[e-mail] if you have any questions or comments related to this correspondence.

Statistical Analysis of Simulated Dissolved Oxygen in the
Proposed Marina at Cape Currituck
A statistical analysis of the simulated dissolved oxygen (DO) in the proposed Marina at Cape Currituck
has been completed. The analysis has been completed for two areas of the proposed Marina, the
Marina basin and the channel leading into the basin. The areas are designated in Figure 1. The Marina
basin contains 921 grid cells and the inlet channel contains 228 grid cells.
Figure 1 Areas Used for the Statistical Analysis
For each area, the depth averaged DO concentration for the 87-day model simulation was extracted at
30-minute intervals. This corresponds to 4,176 DO values for each cell. The number of DO values
below 5.0 mgJL were counted for each cell and that number was divided by the total number of values
to determine the percentage of time the DO was below 5.0 mgJL (referred herein to as PTDOB5). Note
that the total number of values included in the analysis for a given cell was sometimes less than 4,176
because, for sometime intervals, the cell was dry and no DO value was recorded. The PTDOB5 for each
cell in the two areas was then sorted from highest to lowest and then plotted to create a frequency
distribution of the PTDOB5 over all cells. The results for the Marina Basin are shown in Figure 2. As an
example of interpreting the plotted data, it is evident that 20% of the cells have a DO value below 5.0
mgJL 5 to 10% of the time, or similarly, 80% of the cells have a DO value above 5.0 mgJL 95% or more of
the time.

The results for the Inlet Channel are shown in Figure 3. The results for the Inlet Channel indicate very
few occurrences of DO values below 5.0 mg/L (Note the vertical scale range is from 0 to 1%).

Statistical Analysis of Simulated Dissolved Oxygen
Mr. Eadus,
The Division of Water Resources (DWR) Washington Regional Operation Section in collaboration with the
Modeling and Assessment Branch (MAB) and the Classification, Standards & Rules Review Branch (CSRRB)
have completed the review of the proposed marina basin design provided by Quible & Associates, P.C.
(Quible) via correspondence dated April 30, 2019 (entitled Cape Currituck Hydrodynamic and Water
Quality Final Modeling Report), June 3, 2019 (entitled Cape Currituck Hydrodynamic and Water Quality
Final Modeling Report Addendum), September 17, 2019 (entitled Cape Currituck Basin Design Flushing
Model Review Memorandum August 21, 2019) and most recent on March 9, 2020 (entitled Proposed
Marina at Cape Currituck Statistical Analysis of Simulated Dissolved Oxygen). The most recent Quible
correspondence being in response to the DWR Memorandum dated February 13, 2020 entitled "Response
to Cape Currituck Basin Design Questions and Comments." As previously stated within the previous
correspondence, DWR has not received a formal application for the proposed project and any response
or comments provided by DWR are considered part of the pre -application and thus do not represent a
final agency decision.
After completion of the review, DWR considers the model valid and appropriate to reference in the
application process. Based on statistical analysis within your most recent submittal, the model results
suggest than no more 10 percent of depth -averaged Dissolved Oxygen concentrations at a given location
are below 5 mg/I over the 87-day model runtime. The model further predicted residence time of 5 -22.5
days within the proposed marina. DWR would like to state that within 15A NCAC 02B .0220 Tidal Salt
Quality Standards for Class SC Waters (2) states "The best usage of waters classified as SC shall be
maintained as specified in this Rule. Any source of water pollution that precludes any of these uses on

Please find below and attached formal responses to the requests for more information
received by Quible in a letter dated February 13, 2023, and related to the proposed
Powells Point Harbor Marina project. For clarity I have included DWR's comments and
our response (italics) below.
1. It has been acknowledged within this application that some cells within the basin
and channel did result in DO levels below 5.Omg/L during the modeling. The application
states that 20% of the cells have a DO value below 5.0 mg/ L 5% to 10% of the time, or
similarly, 80% of the cells have a DO value above 5.0 mg/ L 95% or more of the time.
The results indicate the water quality in some areas of the proposed basin and access
channel would result in DO levels below the 5.0 mg/L standard found in 15A NCAC 02B
.0220 Tidal Salt Water Quality Standards for Class SC Waters. Please understand that
the DO standard applies to all waters within the basin and access channel at all times.
Revise your plan to comply with the standards found in 15A NCAC 02B .0220 Tidal Salt
Water Quality Standards for Class SC Waters.
Attached are updated flushing models and a Memorandum that explores basin and
channel design alternatives to meet the 5.0 mg/L DO standard. The Memorandum and
model runs were performed by Chris Reed, PhD. We explored a two channel
condition, and a widened channel width (wider than the proposed 60 feet). Neither of
these options improved the DO condition significantly. Multiple model runs were
performed with a range of aeration rates to determine an aeration rate that will provide
sufficient DO to prevent levels in the proposed Marina from dropping below 5.0 mg/L.
The Memorandum is attached, and a copy of the modeling files can be found at the
following Dropbox link:
https://www. dropbox. com/scl/fo/wwfclgpdmzbxvtOpulxph/h?rlkey=vbca5ivb74s25ipgsa2

and are also being delivered to DWR via email. Hard copies of the modeling files can
be mailed or delivered to DWR upon request.

2. The model further predicted residence time of 5 -22.5 days within the proposed
marina with an average water age of 11.5 days. The flushing capacity of the proposed
marina basin appears to be poor and exceeds the recommended flushing times of the
EPA and the North Carolina Water Quality Guidelines for Planning Upland Marina
Development. Revise your plan to comply with the recommended flushing times
provided in the guidance documents.
The provided aeration model run demonstrates that the basin can always meet DWR
water quality standards. Based on preliminary information provided by SOLitude, the
proposed aeration system will turn the water body over 0.92 times per day.
3. In accordance with 15A NCAC 02H .0506 (b) the project should further
demonstrate avoidance and minimization of impacts to open waters and wetlands to
ensure that any remaining surface waters or wetlands, and any surface waters or
wetlands downstream, continue to support existing uses during and after project
completion. As proposed, the project would impact approximately 1.99 acres of 404
wetlands and 2.3 acres of open water. Please explain why additional minimization is not
practicable.
An avoidance and minimization summary along with an Alternatives Analysis was
included in the permit application package. In addition, two alternate basin and channel
designs were explored (discussion included in attached Memorandum) in response to
this RFI. The project as proposed has been reduced in scale to the maximum extent
practicable based on the intended use.
4. Mitigation- please provide a functional assessment of the wetlands to better
justify why the mitigation offered may be appropriate once avoidance and minimization
has been satisfied.
Results of the NC WAM Wetlands Rating Sheet calculation are attached. Based on the
data used, the function rating summary lists an overall wetland rating of Medium.
Please note, the proposed impacts associated with creation of the marina access
channel are limited to wetlands that have been completely overrun by Phragmites.
Wetlands impacts associated with upland development are limited to 0.50 acres or less.
Proposed mitigation is in the form of a payment to a mitigation bank. Mitigation bank
payment was recommended by the USACE during one of the many scoping meetings
that occurred during the planning process of this project.

Introduction
A water quality analysis of the proposed Powells Point Harbor (formerly referred to as the Cape Currituck
Project) was completed to investigate alternatives for improving predicted dissolved oxygen (D.O.) levels
in the harbor. In a previous effort, the EFDC+ model, supported by DSI's EFDC Explorer, was used for the
analysis (reference). This model was used as a starting point for the additional analysis described here.
The previous analysis results indicated that the D.O. in the harbor would fall below 5.0 mg/L for a small
percentage of the time, due to the sediment oxygen demand (SOD) during periods of lower re -aeration.
The low re -aeration occurred during periods of combined low wind speeds and low water velocities.
The objective of this additional modeling is to explore alternative harbor geometries that may improve
the D.O. levels and to estimate aeration rates that will yield D.O. levels above 5.0 mg/L.
Preliminary Analvsis
Prior to completing the modeling analysis, the previous model was modified to improve the model
efficiency and better represent the harbor configuration. The first change was a reduction in the model
spatial resolution. A review of the model grid indicated that the model resolution was extremely high,
and not necessary for robust and reliable simulations. Therefore, the grid resolution was reduced by a
factor of 2 in the lateral direction (not in the vertical). Thus, in two dimensions, the number of grid cells
was reduced by a factor of 4. The reduction in special resolution combined with a subsequent increase
in the model time step reduced the model run times by a factor of 8.
The second change was to set all the grid cells in the harbor to -2.19 feet elevation. In the previous
model some of the cells along the boundary of the grid has very low water depths (< 2.0 feet). A view of
the original grid and the modified model grid are provided in Figures 1 and 2.

Figure 2 Modified Model Configuration
The same model parameters, boundary conditions and simulation period were applied in the modified
model as in the original model analysis. The modified model was run for the base case to assure that it
yielded similar D.O. values as the original model. A comparison of the spatially average D.O. in the
proposed Marina for the duration of the simulation (89 days) is provided in Figure 3. For the majority of
the simulation period the average D.O. values are similar, except for the 10-day period from
approximately 65 to 75 days. This period represents a very calm period in which the wind speeds were
nearly zero, and the water elevation variations over the period were also low, yielding small velocities
into and out of and within the proposed Marina.
The original and modified model simulation results were analyzed to determine the source of the
differences during the 10-day period. Ultimately the differences were traced to differences in the
velocity characteristics in the simulations. The velocity magnitude for a cell in the center of the
proposed Marina is shown in Figures 4 and 5 for the original and modified model. The velocity
magnitudes are generally similar for both simulations, but the simulated velocities for the original model
exhibit some high frequency oscillations prior to and through the 10-day period. These velocities
enhanced the re -aeration of the water column and yielded the higher D.O. values seen in the original
model. However, these oscillations are not realistic and are likely due to numerical effects. The

oscillations are not apparent in the modified model simulation velocities. The modified model yields
lower D.O. values for the 10-day period and is therefore providing conservative results.
Note that the 10-day period with low wind speeds and proposed Marina velocities provides an extreme
set of conditions for evaluating the D.O. in the proposed Marina.

Marina Alternative Designs
Two alternative designs were considered, (1) doubling the channel width and (2) a two -channel
configuration intended to provide better flushing. For the second configuration, a simple channel
alignment was used initially as a screening level approach. If the screening level configuration yielded
improved results a more realistic channel alignment, that was arranged to avoid wetland impacts etc.,
would have been developed. In developing the two -channel model it was determined that the model
area in the bay was too small to accurately represent the flows into and out of the harbor. Therefore,
the model was modified to include a lager portion of the bay. A view of the two -channel model grid and
the increased bay area is shown in Figure 6.

The simulated D.O. levels based on the two alternative model geometries are shown in Figure 7. The
plot shows the spatially average D.O. throughout the proposed Marina during the simulation period.
The D.O. values are similar, and the impact of the alternative designs are negligible.

Aeration Systems
The areas and periods of low D.O. in the harbor may be eliminated with an aeration system. There are
two basic approaches for aeration (a) diffusion systems and (b) mechanical systems.
A diffused aeration system typically operates vertically. It sends up concentrations of bubbles from near
the floor of a water body. Typically, the system comprises blowers, pipes and diffusers. Compressed air
pumps through pipes and filters into the water through the diffusers, which create tiny bubbles. The
bubbles displace and mix the water and create a vertical flow pattern, transferring oxygen into the water
column as they rise.
A conventional mechanical aeration system operates horizontally. It consists of a pump and tubing or a
motor that turns a propeller. The system scoops up water and pushes it out. This churning creates a
current and provides mixing. As the water churns, it draws in and absorbs air. The equipment mixes this
aerated water with the rest of the water in the tank or lagoon and constantly brings in more air to aerate
and mix.
Model simulations have been conducted to demonstrate that an aeration system can improve the D.O.
levels above 5.0 mg/L throughout the proposed Marina. The simulation of aeration in the EFDC model
does not distinguish between diffused or mechanical systems. For either system, D.O. is added directly
to the water column. Also, the EFDC model currently does not allow for a direct external source of D.O.,
and therefore it was necessary to introduce a small inflow into the proposed Marina with a near
saturated D.O. level. A range of aeration rates were applied. The flow rates used ranged between 0.025
to 0.5 m3/s with a D.O. level of 8 mg/L. The D.O. loadings for each case are summarized in Table 1.

The results for each case are presented below. A plot of the initial case of no aeration is shown in Figure
8. The location of the simulated aeration heads is shown in Appendix A. The plot shows the maximum
and minimum D.O. that occurs in the proposed Marina and the spatially averaged D.O. during the
simulation period. The results for Cases 2 through 4 are compared to the no -aeration Case in Figure 9.
This plot only shows the minimum D.O. occurring in the proposed Marina. The results indicate that a
delivery of 415 kg/day of D.O. will improve the D.O. levels in the proposed Marina sufficiently to
maintain the D.O. levels above 5.0 mg/L. Note that this level of D.O. delivery is driven by the extreme
10-day period and less aeration will be required for the majority of the time. A review of the results
presented in Figure 9 indicates that an aeration rate of 17 kg/day will provide sufficient D.O. to prevent
levels in the proposed Marina from dropping below 5.0 mg/L.

4. DISCLAIMER. SOLitude is not responsible for the failure of any treatment, equipment installation, or
other work that result from dam or other structural failures, severe weather and storms, flooding, or other
acts of God that are outside of the control of SOLitude.
Customer understands and acknowledges that there are irrigation restrictions associated with many of the
products used to treat lakes and ponds. The customer is responsible for notifying SOLitude in advance of
the contract signing and the start of the contract if they utilize any of the water in their lakes or ponds for
irrigation purposes. The customer accepts full responsibility for any issues that may arise from the irrigation
of turf, ornamentals, trees, crops, or any other plants as a result of treated water being used by the
customer for irrigation without the consent or knowledge of SOLitude.
Although there is rarely direct fish toxicity with the products used for treatment when applied at the
labeled rate, or the installation and normal operation of the equipment we install, there is a risk under
certain circumstances of significant dissolved oxygen drops. This risk is most severe in times of extremely
hot weather and warm water temperatures, as these are the conditions during which dissolved oxygen
levels are naturally at their lowest levels. Oftentimes lakes and ponds will experience natural fish kills under
these conditions even if no work is performed. Every effort, to include the method and timing of
application, the choice of products and equipment used, and the skill and training of the staff, is made to
avoid such problems. However, the customer understands and accepts that there is always a slight risk of
the occurrence of adverse conditions outside the control of SOLitude that will result in the death of some
fish and other aquatic life. The customer also understands and accepts that similar risks would remain
even if no work was performed. The customer agrees to hold SOLitude harmless for any issues with fish or
other aquatic life which occur as described above, or are otherwise outside the direct control of the
SOLitude, unless there is willful negligence on the part of SOLitude.
While SOLitude Lake Management LLC makes every effort to thoroughly inspect the site before providing
this contract proposal or beginning any work, it is possible, without fault or negligence, that unforeseen
circumstances may arise, or that hidden conditions on the site might be found in the course of the
performance of the contract work, which would result in additional time or material costs that exceed this
contract pricing. Should this occur, the customer will be notified of these unforeseen circumstances or
conditions and be responsible for the costs associated with remedying. By signing this agreement, the
customer acknowledges that they have informed SOLitude Lake Management® of all known and
relevant current site conditions that would be reasonable to expect could affect our ability to successfully
complete the contract work.
5. INSURANCE AND LIMITATION OF LIABILITY. Solitude will maintain general liability and property
damage insurance as necessary given the scope and nature of the Services. The Company will be
responsible for those damages, claims, causes of action, injuries or legal costs to the extent of its own
direct negligence or misconduct, and then only to an amount not to exceed the annual value of this
Agreement. In no event will any party to this Agreement be liable to the other for incidental,
consequential or purely economic damages.

6. FORCE MAJEURE. The Company shall not be liable for any delay in performing the Services, nor
liable for any failure to provide the Services, due to any cause beyond its reasonable control.
7. ANTI -CORRUPTION AND BRIBERY. Each party represents that neither it nor anyone acting on its
behalf has offered, given, requested or accepted any undue financial or other advantage of any kind in
entering into this Agreement, and that it will comply with all applicable laws and regulations pertaining to
corruption, competition and bribery in carrying out the terms and conditions of this Agreement.
8. GOVERNING LAW. This Agreement shall be governed and construed in accordance with the laws
of the state in which the Services are performed.
9. ENTIRE AGREEMENT. This Agreement constitutes the entire agreement between the parties with
respect to the subject matter and replaces any prior agreements or understandings, whether in writing or
otherwise. This Agreement may not be modified or amended except by written agreement executed by
both parties. In the event that any provision of this Agreement is determined to be void, invalid, or
unenforceable, the validity and enforceability of the remaining provisions of this Agreement shall not be
affected.
10. NOTICE. Any written notice provided under this Agreement may be sent via overnight mail,
certified mail, hand delivery or electronic mail with delivery confirmation, to the individuals and addresses
listed below.
11. BINDING. This Agreement shall inure to the benefit of and be binding upon the legal
representatives and successors of the parties.
12. FUEL/TRANSPORTATION SURCHARGE. Like many other companies that are impacted by the price of
gasoline, a rise in gasoline prices may necessitate a fuel surcharge. As such, the Company reserves the
right to add a fuel surcharge to Customer's invoice for any increase in the cost of fuel as measured above
the same time period in the prior year (by the National U.S. Average Motor Gasoline -Regular Fuel Price per
Gallon Index reported by the U.S. Department of Energy). The surcharge may be adjusted monthly (up or
down) with the price of gasoline.
13. E-Verify. Solitude Lake Management LLC utilizes the federal E-Verify program in contracts with
public employers as required by Florida State law, and acknowledges all the provisions of Florida Statute
448.095 are incorporated herein by reference and hereby certifies it will comply with the same.

DIFFUSER INSTALLATION
The effectiveness of the Robust -Aire TM system depends on the location of the diffusers in the pond. Place the
Robust-AireTm Diffusers equidistant from each other at a depth that is representative for most of the pond.
Please contact Kasco with any questions about placement or system operation.
CAUTION: Do not use boats that tip easily for installation.
Always wear a personal flotation device.
1. Kasco recommends marking the location of each diffuser at the surface with a buoy.
2. Unroll the SureSinkTm Tubing on shore to remove any twists or knots. Performance will decrease if the
tube is not properly uncoiled.
3. Each tubing length is 100 feet. If more than one length of tubing is required to reach a diffuser location,
connect any additional tubes according to the SureSinkTm Tubing instructions. Unroll these tubes as you
did the first tube. You can load multiple rolls of tubes into a boat and connect them as needed while
making your way to the proposed diffuser location. You can also connect any number of 100' lengths
together and have someone assist in feeding it from shore. Cut off any excess tubing at the shore before
connecting to the compressor.
4. Drop the loose end of the tubing near the compressor cabinet. Allow a few extra feet of tubing to work
with so the tube will reach the cabinet after trenching between the shore and the compressor.
5. Drive the boat in reverse to keep tubing clear of the propeller and slowly make your way to the marking
buoy, placing the tubing as you go.
6. Once you reach the marked buoy, thread a rope through the two holes of the diffuser base. Pull through
until the midpoint of the rope is at the diffuser base.
7. While holding the two ends of the rope, gently lower the diffuser assembly into the water.
8. Continue slowly lowering the assembly until it reaches the bottom of the pond. The diffuser will always
land right side up.
9. The Robust-AireTm Diffuser should now be seated properly on the bottom of the pond. You can remove
the rope by pulling on one end. For ease of future maintenance, Kasco recommends leaving the rope
looped through diffuser base and tying both ends to a marker buoy or duck decoy. This will allow you to
easily locate diffusers and pull them to the surface for maintenance.
10. Repeat the process for additional Robust-AireTm Diffuser locations.

LARGE CABINET INSTALLATION
Choose a location far enough from shore to avoid potential flooding. If you use plantings to help hide the
cabinet, be sure that both the inlet and the outlet vents are clear, as the compressor requires airflow to
prevent overheating. The best foundation options include pea gravel, rubber mulch, and cement.
Place the assembly directly on the ground or attach it to a concrete pad. Use the holes on the bottom
flanges to anchor the cabinet.
Place the cabinet adjacent to the electrical service which will power the system. The cabinet has 6-foot
power cords with plugs. DO NOT USE EXTENSION CORDS.
NOTE For remote manifold installation information, see supplementary instruction sheet.

STARTUP PROCEDURE
IMPORTANT INSTALLATION WARNING
Thermal stratification refers to layering that occurs in some lakes and ponds when warmer water sits on top
of colder, denser water toward the lake bottom.
If you install your unit into a body of water that is extremely stratified, use caution when starting the system.
In some cases, colder water sitting on the bottom could hold gases that can be harmful to fish. Often, the
colder bottom water also contains little or no dissolved oxygen.
A simple test for thermal stratification is to use a thermometer to gradually check for water temperature
changes between the top and bottom of the lake or pond. Measure temperature every two feet of depth.
Keep the thermometer at each depth long enough to take an accurate temperature reading. Then quickly
bring the thermometer to the surface and record the temperature at each depth.
If the colder water (anything 4 OF colder than surface) represents more than 30% of the overall volume, start
aeration at a slower pace by running the system for short intervals only. For a stratified lake, a suggested
start-up interval might include running the system one hour per day for one week and gradually increasing
the duration until the system is running continuously. Lakes and ponds react differently to diffused aeration,
so exact time frames can be difficult to predict. Sunny days are preferable to cloudy days for system start-
up, since photosynthesis will supplement oxygen levels as the water is mixed.
If you have questions about this procedure, please contact your distributor or e-mail Kasco Customer
Service at [e-mail].
WINTER OPERATION
NOTE The system owner assumes all risks of operating the Robust -Aire TM system during winter months.
Operating the Robust -Aire TM system during the winter or in freezing temperatures may create open areas
of water at the diffuser locations. Ice surrounding those areas will be thin. Use extreme caution in the area
to avoid injury or fatality from falling into the water. Use signs to indicate the danger to others. Check your
local laws and ordinances; some areas require warning signs to be posted.
In climates where temperatures fall below freezing, Kasco recommends insulating the air lines from the
compressor cabinet to a minimum of 3 feet into the water (use low water level for reference). Prevent ice
buildup in the lines by using closed cell polyurethane foam to insulate. Ice buildup can block the flow of air
to your diffuser and cause damage to your compressor. Insulation should pass through the ice, into the
open water below.
Moving the diffusers closer to shore in winter will allow a small area of the shoreline to remain open,
preventing winter kill.

WaC resource list
This report is an automatically generated list of species and other resources such as critical
habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's
(USFWS) jurisdiction that are known or expected to be on or near the project area referenced
below. The list may also include trust resources that occur outside of the project area, but
that could potentially be directly or indirectly affected by activities in the project area.
However, determining the likelihood and extent of effects a project may have on trust
resources typically requires gathering additional site -specific (e.g., vegetation/species
surveys) and project -specific (e.g., magnitude and timing of proposed activities) information.
Below is a summary of the project information you provided and contact information for the
USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to
each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI
Wetlands) for additional information applicable to the trust resources addressed in that
section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of
project level impacts.
The primary information used to generate this list is the known or expected range of each
species. Additional areas of influence (AOI) for species are also considered. An AOI includes
areas outside of the species range if the species could be indirectly affected by activities in
that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at
the dam site, may indirectly impact the species by reducing or eliminating water flow
downstream). Because species can move, and site conditions can change, the species on this
list are not guaranteed to be found on or near the project area. To fully determine any
potential effects to species, additional site -specific and project -specific information is often
required. .0p V
Section 7 of the Endangered Species Act requires Federal agencies to "request of the
Secretary information whether any species which is listed or proposed to be listed may be
present in the area of such proposed action" for any project that is conducted, permitted,
funded, or licensed by any Federal agency. A letter from the local office and a species list
which fulfills this requirement can only be obtained by requesting an official species list from
either the Regulatory Review section in IPaC (see directions below) or from the local field
office directly. %.
For project evaluations that require USFWS concurrence/review, please return to the IPaC
website and request an official species list by doing the following:
1. Log in to IPaC.
2. Go to your My Projects list.
3. Click PROJECT HOME for this project.
4. Click REQUEST SPECIES LIST.
Listed species= and their critical habitats are managed by the ccoiogical Services rrogram of
the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic
and Atmospheric Administration (NOAA Fisheries).
Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown
on this list. Please contact NOAA Fisheries for species under their jurisdiction.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also

NAME BREEDING SEASON

Bald Eagle Haliaeetus leucocephalus Breeds Sep 1 to jul 31
This is not a Bird of Conservation Concern (BCC) in this area,
but warrants attention because of the Eagle Act or for potential
susceptibilities in offshore areas from certain types of
development or activities.
Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely
to be present in your project area. This information can be used to tailor and schedule your
project activities to avoid or minimize impacts to birds. Please make sure you read
"Supplemental Information on Migratory Birds and Eagles", specifically the FAQ section titled
"Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to
interpret this report.
Probability of Presence( )
<\ON
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s)
your project overlaps during a particular week of the year. (A year is represented as 12 4-
week months.) A taller bar indicates a higher probability of species presence. The survey
effort (see below) can be used to establish a level of confidence in the presence score. One
can have higher confidence in the presence score if the corresponding survey effort is also
high
LIL
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in
the week where the species was detected divided by the total number of survey events
for that week. For example, if in week 12 there were 20 survey events and the Spotted
Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in
week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of presence
in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week
12 (0.25) is the maximum of any week of the year. The relative probability of presence on
week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the
probability of presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season( )

Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds
across its entire range. If there are no yellow bars shown for a bird, it does not breed in your
project area.
Survey Effort ( )
Vertical black lines superimposed on probability of presence bars indicate the number of
surveys performed for that species in the 10km grid cell(s) your project area overlaps. The
number of surveys is expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data ( )
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are
based on all years of available data, since data in these areas is currently much more sparse.

The potential for eagle presence is derived from data provided by the Avian Knowledge Network (AKN).. The
AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried
and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project
intersects, and that have been identified as warranting special attention because they are a BCC species in
that area, an eagle (Eagle Act requirements may apply). To see a list of all birds potentially present in your

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory
birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all
birds at any location year round. Implementation of these measures is particularly important when birds
are most likely to occur in the project area. When birds may be breeding in the area, identifying the
locations of any active nests and avoiding their destruction is a very helpful impact minimization measure.
To see when birds are most likely to occur and be breeding in your project area, view the Probability of
Presence Summary. Additional measures or permits may be advisable depending on the type of activity
you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the list of migratory birds that potentially occur in my specified
location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC), and other
species that may warrant special attention in your project location.
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge
Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science
datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid
cell(s) which your project intersects, and that have been identified as warranting special attention because
they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a
particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area.
It is not representative of all birds that may occur in your project area. To get a list of all birds potentially
present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially
occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by
the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey., banding, and
citizen science datasets. k
Probability of presence data is continuously being updated as new and better information becomes
available. To learn more about how the probability of presence graphs are produced and how to interpret
them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering or migrating in my area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering,
migrating or year-round), you may query your location using the RAIL Tool and look at the range maps
provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a bird
on your migratory bird species list has a breeding season associated with it, if that bird does occur in your
project area, there may be nests present at some point within the timeframe specified. If "Breeds
elsewhere" is indicated, then the bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their
range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin
Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in
the continental USA; and
"Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either
because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in
offshore areas from certain types of development or activities (e.g. offshore energy development or
longline fishing).

Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in
particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of
rangewide concern. For more information on conservation measures you can implement to help avoid and
minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and
groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data
Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to
you in your project review. Alternately, you may download the bird model results files underlying the portal
maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird
Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use throughout the
year, including migration. Models relying on survey data may not include this information. For additional
information on marine bird tracking data, see the Diving Bird Study_ and the nanotag studies or contact
Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain ermi* to avoid violating

The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of
priority concern. To learn more about how your list is generated, and see options for identifying what other
birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds
potentially occurring in my specified location". Please be aware this report provides the "probability of
presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint.
On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar)
and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key
component. If the survey effort is high, then the probability of presence score can be viewed as more
dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack
of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying
what birds of concern have the potential to be in your project area, when they might be there, and if they
might be breeding (which means nests might be present). The list helps you know what to look for to
confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or
minimize potential impacts from your project activities, should presence be confirmed. To learn more
about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to
avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

NOTE: This initial screening does not replace an on -site delineation to determine whether
wetlands occur. Additional information on the NWI data is provided below.
Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level
information on the location, type and size of these resources. The maps are prepared from the analysis of
high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A
margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular
site may result in revision of the wetland boundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image
analysts, the amount and quality of the collateral data and the amount of ground truth verification work
conducted. Metadata should be consulted to determine the date of the source imagery used and any
mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There
may be occasional differences in polygon boundaries or classifications between the information depicted
on the map and the actual conditions on site.
Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of
aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or
submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and

nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also
been excluded from the inventory. These habitats, because of their depth, go undetected by aerial
imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe
wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or
products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local
government or to establish the geographical scope of the regulatory programs of government agencies.
Persons intending to engage in activities involving modifications within or adjacent to wetland areas should
seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory
programs and proprietary jurisdictions that may affect such activities.

DO MONITORING PLAN

Powells Point Harbor
Resort Marina Development
Dissolved Oxygen Monitoring Plan
January 22, 2024
1.0 BACKGROUND
Powells Point Harbor is a proposed resort marina community that would provide deep
water access to the Albemarle Sound and Atlantic Intracoastal Waterway (AIW) from the
west side of Currituck County.
A total of four (4) flushing models were performed during the planning phase of the
project and the final channel and basin configuration is shown on the attached Figure 1.
As configured, the model predicted that there would be instances during the warmest
months of the year where dissolved oxygen (DO) levels would be slightly below the
5mg/L threshold in 20% of the cells 10% of the model run time of 87 days. Therefore,
the applicant proposes to use a simple diffused air system that will supply 475 kg/day of
forced air into twelve submerged aeration heads that are spread around the proposed
marina basin. A model was prepared and submitted to NC DEQ DWR demonstrating
that under this scenario there is not a predicted incident of DO below 5 mg/L in the basin
or channel at any time.
2.0 MONITORING PROPOSAL
A total of seven monitoring stations are proposed (by coordinates) as shown on the
attached Figure 1-DO Monitoring Locations. During the months of June through
September DO readings would be collected on one -foot intervals (from top to bottom)
and in general accordance with EPA Region 4 SESDPROC-102-R4 (or most recent) on
a weekly basis. During the months of October through May, DO concentrations would
be collected on a monthly basis. Environmental scientists with Quible will oversee the
sample collection for the first year and any adjustments to the sampling frequency,
location or aeration volumes can be made. Quible would deliver to DWR, Currituck
County and other interested parties a certified (professional seal or acceptable sworn
statement) summary of findings on a quarterly basis or as frequently as DWR or
Currituck County requires.
DO monitoring would be performed using a properly calibrated instrument that is capable
of collecting DO measurements in mg/L. Quible will assist the marina with purchase and
maintenance of the appropriate DO sensor.

2022 SAV UPDATE AND ESSENTIAL FISH HABITAT ASSESSMENT

August 1 st , 2022 SAV Survey
Powells Point Harbour, Powells Point, Currituck County, NC
I. Introduction
The purpose of this report is for Quible & Associates, P.C. (Quible) to provide state and
federal regulatory agencies with an updated Submerged Aquatic Vegetation (SAV)
survey conducted in the Albemarle Sound/North River confluence immediately adjacent
to and in close proximity of the subject property located in Currituck County. The
Physical Property (Site) is located on the west side of US 158 and adjacent to Kilmarlic
Golf Course located in Powells Point, North Carolina (Exhibit A Relevant portion of
USGS Topographic Quadrangle -Point Harbor). The Site is accessible through the
Kilmarlic Golf Course via West Side Lane.
The Study Area for this updated SAV survey is shown on the attached Exhibit B,
includes the proposed future boat channel and adjacent areas in the Albemarle Sound.
The August 1st, 2022, SAV survey was conducted to examine the substrate of shallow
waters adjacent to the Site for the presence or absence of SAV, and to document the
conditions that may relate to SAV habitat. The SAV survey was conducted during the
peak growing season as required by resource management agencies.
Generally, low salinity SAV found in this area of the Albemarle Sound prefers low energy
shallow water areas where significant photic penetration through the water column to the
substrate persists. These species generally go dormant (with some exceptions) in the
winter months as water temperatures decrease and foliage dissipates.
II. Methodology
The accompanying base map (Exhibit B) includes 2020 aerial photography provided by
Currituck County with the study area identified, along with sampling stations and
collected water depths. Water depth surveying was conducted throughout the Study
Area on August 1st, 2022. Depths were collected by Environmental Scientists from
Quible using survey -grade GPS.
SAV surveying consisted of establishing five transects extending to a depth of -3.5 to -
4.0' (NWL) within and adjacent to the proposed channel alignment and a cursory
analysis at depths exceeding -4.0' (NWL) within the Study Area. The detailed survey
involved establishing and reviewing conditions along a series of transects and sampling
stations to fully understand the extent and coverage of any SAV resource. The Braun-
Blanquet method was utilized for this survey. At each sampling station, water depth,
substrate type, and SAV scoring and identification was performed and recorded. After an
initial reconnaissance, survey grade GPS was used to navigate to each sampling station
along the transects. At each station, a 0.25-meter x 0.25-meter PVC quadrat was tossed
haphazardly' into the water. This was done in triplicate at each sampling station to better
understand the total cover and species of SAV throughout the Study Area (if any SAV
was identified). Sampling/observation of the substrate was performed using a snorkel
and mask in multiple free dives.
The Braun-Blanquet method uses a scoring scale of 0 to 5 to determine the coverage of
sea grasses based on ranges of SAV coverage. Each number starting with zero, gives a
range of percent SAV coverages, with zero being bare (no grass) and 5 being the
highest at >75% coverage. The scale is as follows:

August 1 st , 2022 SAV Survey
Powells Point Harbour, Powells Point, Currituck County, NC
0 = bare
0.1 = <5% cover with a solitary individual/shoot
0.5 = <5% cover with few individuals/shoots
1 = <5% cover with numerous individuals/shoots
2 = >5% cover and <25% cover
3 = >25% cover and <50% cover
4 = >50% cover and <75% cover
5 = >75% cover
III. Findings and Observations
On August 1st, 2022 the winds were 12-15 mph, with stronger gusts from the southwest.
Wind, tide and precipitation rates resulted in above Normal Water Level (NWL)
conditions for the Study Area, evidenced by wrack lines, beach shelving and water
marks on cypress trees and marsh grass.
Water depths collected at each of the sampling stations are plotted on Exhibit B (all
depths relative to NWL). Included as Exhibit C is a spreadsheet that includes sampling
station coordinates, depths and SAV coverage.
The only evidence of SAV in this area included one small sparse patch (point 131/132)
and one individual sprig of SAV at point 109. This minor occurrence of SAV was most
likely from ripped up Ruppia maritima (Widgeon Grass) being carried from another
location and rooting. This suggests possible rooted SAV in other nearby areas where
habitat is more compatible for SAV growth. This species is a common occurrence in the
Albemarle estuarine system.
The substrate type throughout the Study Area is sand dominated overlying clays, peat
and clayey sands. Near shore areas are predominately relic peat beds with scattered
stumps and wood debris originating from the eroding shoreline. There were also small
gravel beds found in some locations along the shoreline/near shore areas. Some small
areas of exposed clay were found just past the areas of peat in the near shore. The sand
bottom in the offshore area was highly rippled and aligned parallel to the shore by
prevailing current and wind direction. There are some large-scale bars and troughs that
are visible in aerial photography and evident from water depth soundings (See attached
Exhibit B).
IV. DISCUSSION and CONCLUSION
The findings of this study indicate that the Study Area is not ideal for SAV growth and is
not likely SAV Habitat. This is consistent with our initial SAV survey along the entire
shoreline of the site in 2017. High energy, shifting sands, and low visibility combine to
make the Study Area inhospitable for most SAV growth, with the exception of some
sparse occurrences that take root form rafts of ripped up SAV passing through from wind
events, but most likely will not survive or spread due to high energy and sand
movement.
This survey work was completed before any significant tropical storm systems affected
our area. It should also be noted that Quible scientists reviewed two known SAV areas
nearby and confirms that regionally, SAV growth seems to be near -normal for the Upper
Albemarle/North River system.

I. INTRODUCTION
This Essential Fish Habitat (EFH) Assessment has been prepared by Quible & Associates, P.C.
(Quible) as a component of a CAMA Major Permit and Department of Army Permit required for
dredge and fill activities and development within Areas of Environmental Concern (AEC) associated
with the Cape Currituck Marina Resort Development (Figure 1-Relevant Portion of USGS
Topographic Quadrangle -Point Harbor).
An EFH assessment was requested by the US National Marine Fisheries Service (NMFS) in
response to a request to dredge a 60 feet wide channel that is 3,300 feet in length to a depth of
-8.0 relative to normal water level (NWL) and connecting an existing 10.4-acre pond (Broadhead
Pit) to the Albemarle Sound as shown on the attached Figure 2-Proposed Development
Concept.
As defined in the Magnuson -Stevens Fishery Conservation and Management Act (MSFCMA),
EFH's are considered "those waters and substrate necessary to fish for spawning, breeding,
feeding, or growth to maturity".
II. PROJECT SUMMARY
The Project Area (Site) is located on the western shore of the Lower Currituck mainland (Figure 1).
The purpose of the proposed project (Cape Currituck Marina Resort) is to develop a deep -water
marina resort community providing water access to the Albemarle Sound from the west side of
Currituck County. Currituck County does not currently have a marina resort development (with
deep water access suitable for sailboats and larger vessels using the ICW) on the Albemarle
Sound.
Specific design elements include the creation of a 208-slip full -service marina (fuel, pump out and
ships store) and resort community offering mooring opportunities for up to 160 residential units
(condominiums, cottages and townhomes), transient slips serving boaters on the ICW, and a
mooring opportunity for a proposed Ferry System serving the Albemarle Region.
The marina will be accessed from the Albemarle Sound via a 60 feet wide and 3,300 linear feet
long boat channel dredged to a depth of -8.0 feet relative to normal water level (NWL). 1,700 feet
of the channel will be dredged in the open waters of the Albemarle Sound. An additional 1,600
linear feet will be cut through a stand of Phragmites australis (Phragmites) dominated wetlands.
The marina will be constructed within the existing 10.4-acre pond (former Broadhead Pit) resulting
from a past sand mine operation. The attached Figure 2 -Proposed Development Concept that
the developer is seeking to permit.
Impacts for the proposed development include the excavation of the channel in the Albemarle
Sound (2.34 acres), excavation of the 1,600 linear feet by 60 feet wide channel through riparian
wetlands (1.43 acres of P. australis dominated wetlands) and 0.48 acres of proposed wetlands fill
that is needed for road crossings, stormwater management and upland development. All
acreages of proposed impacts are calculated using AutoCAD software, and based on USACE
confirmed wetlands locations, surveyed boundaries and Site features.
III. ANALYSIS OF SHELLFISH AND FINNED FISH, VEGETATION AND SUBSTRATE
The NCDEQ website [http://portal.ncdenr.org/web/mf/habitat/maps] was queried as part of this
Assessment. Based on the GIS data presented on the various DEQ pages, there do not
appear to be any mapped Fishery Nursery Areas, Hard Bottom Habitat Areas, Shell Bottom
Habitat areas, or SAV Habitat Areas (field confirmed by physical survey performed in 2017).

Cape Currituck Marina Resort October 9, 2018
Powells Point, Currituck County, NC
The project area does not appear on the Soft Bottom Habitat Area maps. However, sands, silty
sands and soft sediments do occur in the project area. Based on our review of the shoreline and
near shore environment to depths of approximately -10.0 feet (NWL) the deeper waters of the
project area support hard crab fishing (evidenced by crab pots in waters of depths around -7.0 to
-8.0 feet).
The project area shoreline is shown on Coastal Habitat Protection Plan (CHPP) maps and the near
shore of the project area does provide Water Column Habitat (0-3 and 3-6 feet) as listed in:
http://Portal.ncdenr.org/web/mf/habitat/water-column#Function.
A review of the South Atlantic Marine Fisheries Council (SAMFC) Essential Fish Habitat web
mapping tool
(http://myfwc.maps.arcgis.com/apps/webappviewer/index.html?id=961 f8908250a404ba99fac3a37a
c723) shows that there are no mapped EFH's for any of the species managed by the
SAMFC. A review of the Mid -Atlantic Marine Fisheries species list includes species that use the
Albemarle Sound up to the Highway 17 Bridge (reference from List of Essential Fish Habitat
Species by Waterbody in North Carolina -July 2009) and includes the following:

Quible & Associates, P.C. conducted an extensive reconnaissance of the substrate along the entire
project area shoreline during our SAV Survey. Substrate sampling included establishing transects
and reviewing the substrate firsthand by performing three or more shallow dives at each sampling
location along the transect (please refer to the SAV Report -Attachment A). At each sampling
station along the transects shown on Figure 1 of the SAV Report, a meter by meter quadrangle
was haphazardly tossed (to produce a random result) three times and an experienced
environmental scientist estimated the presence or non -presence of SAV (percent cover and
species), shellfish, sediment type and any other general observations (e.g. wood, crab pot). In
addition to the formal SAV Survey peformed in 2017, Quible conducted extensive water quality
monitoring of the near shore and areas of deeper water (-8.0 feet NWL) along with collecting core
samples using a Vibracore machine within the Project Area. Division of Coastal Management
representatives reviewed the project area in 2017 and confirmed Quible's findings related to
general sediment types and absence of SAV Habitat.
A. Shellfish and Finned Fish
In order to accurately represent shellfish and finned fish species composition in the vicinity of the
project area, NC DEQ Division of Marine Fisheries (DMF) and NMFS were asked if any sampling
data was available from this area via email dated September 20, 2018. Based on correspondence

Cape Currituck Marina Resort October 9, 2018
Powells Point, Currituck County, NC
with NC DMF, it does not appear that there is any fish or shellfish sampling data available for this
area. NMFS did not respond to the email request.
There are areas of substantial SAV habitat mapped to the north of the project area and these SAV
habitat areas are likely EFH for several species of finned fish. However, the SAV habitat areas are
about 1.3 miles north of the project area.
Based on the substrate analysis, review of readily available information on the States GIS web
mapping portals, and correspondence with DMF representatives, the project area does not appear
to support shellfish or shellfish habitat, other than the occasional Asiatic clam (Corbicula sp.)
occurrence.
B. Submerged Aquatic Vegetation (SAV) Survey
A comprehensive SAV Survey was conducted within the project area on July 13, 2017. The final
SAV Report has been included as Attachment A. The project area does not support SAV growth
and this was confirmed during a Site visit by NC DEQ DCM and DMF staff on August 15, 2017.
Monitoring of the project area for water quality parameters (to be used in basin flushing model) and
collection of core samples occurred during the growing season of 2018. No SAV presence was
observed at any time over the last two summers (two consecutive years with documented absence
of SAV). In addition, an SAV survey was conducted in 2008 and no SAV was reported at that
time. It is likely that the project area does not support SAV due to high wind and wave energy and
a substrate that does not readily support SAV rooting (thin veneer of shifting sands overlying stiff
hard clays, sand clays and peat with some areas of exposed marsh mat).
C. Substrate
The surficial sediments were described at each of the 61 sampling stations and descriptions are
included in Table 1 of the SAV Survey Report (Attachment A). In addition, four three-inch core
samples were collected from within the proposed channel alignment. The cores were collected
using a Vibracore setup (vibratory motor, concrete vibrator and clamp attachment custom
manufactured for Quible) and tripod and winch extraction mechanism. Photographs of the
Vibracore setup are included as Attachment B. A descriptive core sample lithology along with
corresponding depths and a cross section are included as Attachment C.
Surficial sediments in the near shore are best described as a veneer of medium to coarse sands
overlying stiff clays and sandy clays with relic peat beds and marsh mat occurring at the shoreline.
Cross sections show that in the Albemarle Sound portions of the project there is a veneer of
medium to coarse sand overlying clays and sandy clays of varying thicknesses. Sediments
observed in the core samples collected in the marsh are generally the same as sediments found in
the Albemarle, with the exception that there are additional sequences of back bay/marsh sediments
found overlying the layers of medium to coarse sands and clays. Sediments in the core samples
represent typical transgressive and regressive sea level sequences.
IV. ANALYSIS OF POTENTIAL ADVERSE IMPACTS
A. Water Quality Impacts
Negative water quality effects from removal of sediments and potential "stirring" of sediments
during hydraulic dredging activities may occur in any typical dredge project. Therefore, a dredge
moratorium will be observed as recommended by NC DEQ DMF and NOAA NMFS.
The basin and channel connection to the Albemarle Sound are currently being modeled to
determine what water quality impacts can be expected in terms of dissolved oxygen and residence
time within the basin, channel and receiving waters of the Albemarle. The DWR TMDL Monitoring

Cape Currituck Marina Resort October 9, 2018
Powells Point, Currituck County, NC
Unit approved a water quality monitoring schedule for the project. Quible measured water quality,
weather data and corresponding wind tide fluctuations in the project area from June 2018 through
September 2018. All the water quality and site -specific weather data will be submitted to the DWR
TMDL Monitoring Unit when the hydraulic model has been completed and submitted.
A full evaluation of any water quality impacts associated with the proposed channel and marina
basin connection to the Albemarle Sound cannot be completed until a hydraulic model has been
constructed. Results of the flushing model will be submitted to NC DWR, NC DCM and USACE
when complete.
B. Increase in boater traffic
The project as proposed will increase boater traffic. An increase in boater traffic can lead to
adverse impacts and the developer will need to propose design controls and mitigative measures to
limit turbidity associated with boat wake in the channel, limit erosive force caused by boat wake in
the channel that could lead to wetlands erosion. The marina will need to have dedicated sewer
pump out stations, mechanisms/restrictions (by way of covenants etc.) in place to prohibit any in
water boat repairs and Spill Prevention and Countermeasure Control Plan(s) (SPCC) for fuel
storage and delivery as well as the sewage pump out facilities. Currituck County is requiring that
the marina be a certified Clean Marina and there will be no stormwater discharges to surface
waters as a result of the proposed project.
C. Loss of habitat.
Habitat loss will be limited to loss of shallow water habitat for the creation of the channel and the
loss of riparian wetlands (area picked for channel location is dominated by Phragmites australis).
V. PROPOSED MITIGATIVE MEASURES
Mitigation for the proposed project is focused on offsetting habitat loss and restoring lost wetland
habitat as a result of past mining and canal dredging activities.
Impacts associated with the proposed project include
1. Dredge of the channel in the Albemarle (2.34 acres)
2. Dredge of the channel through P. australis (riparian wetlands) (1.46 acres)
3. Fill of Non -Riparian wetlands for upland development (0.48 acres)
Proffered mitigation for the unavoidable and proposed impacts includes:
1. Payment to a mitigation bank at a ratio of 1:1 for riparian wetlands impacts and 2:1 for
Non -Riparian wetlands impacts. See attached Letters of Credit Availability.
2. Implementation of an invasive species eradication program coupled with reintroduction of
native species in the wetland's areas dominated by P. australis for a period of seven years.
See attached Invasive species eradication quote along with prices for reintroduction of
native seed and emergent wetlands plants.
3. Construction of a breakwater along the channel through the wetlands to diffuse erosive
velocities created by boat traffic will be installed as well as a breakwater in the Albemarle to
limit the need for maintenance dredging.
All in water structures will require special consideration during design and implementation to
account for manatees and sturgeon. All appropriate USFWS Guidance documents will be
followed related to any endangered or threatened species.

VI. CONCLUSIONS
The lack of SAV, hard bottom and shellfish habitat in the project area indicates that while the
water column and soft sediment habitats exist, the project area itself is likely not Essential Fish
Habitat for any of the SAFMC or MAFMC managed species.

July 13t", 2017 SAV Survey
Cape Currituck, Powells Point, Currituck County, NC
I. Introduction
The purpose of this report is for Quible & Associates, P.C. (Quible) to provide state and
federal regulatory agencies with a report of findings for a Submerged Aquatic Vegetation
(SAV) survey conducted within the Albemarle Sound immediately adjacent to and in
close proximity of the subject property (Study Area) which is located in Currituck County.
Cape Currituck is a 119.96 Acre property (Site) located on the west side of US 158 and
adjacent to Kilmarlic Golf Course located in Powells Point North Carolina (Exhibit A
Relevant portion of USGS Topographic Quadrangle -Point Harbor). The Site is
accessible through the Kilmarlic Golf Course via West Side Lane.
The Study Area shown on the attached Exhibit B, includes approximately 1,800 linear
feet of shoreline and extends 1,600 feet into the Albemarle Sound. The July 13, 2017
SAV survey was conducted to examine the substrate adjacent to the Site to confirm the
presence or absence of SAV, and to document the conditions that may relate to SAV
habitat. The SAV survey was conducted during the peak growing season as required by
resource management agencies.
Generally, low salinity SAV found in this area of the Albemarle Sound prefers low energy
shallow water (five feet or less) where significant photic penetration through the water
column to the substrate persists. These low salinity species generally go dormant (with
some exceptions) in the winter months as water temperatures decrease and foliage
dissipates.
II. Methodology
The accompanying base map (Exhibit B) includes 2016 aerial photography provided by
Currituck County with the study area identified, along with SAV sampling stations and
collected water depths. Water depth surveying was conducted throughout the Study
Area on July 13th, 2017 using survey -grade GPS coupled to a Seafloor Systems Single
Beam Echo -Sounder. A bathymetric map (Exhibit B) was generated using the data
gathered during the survey and AutoCAD software was used to illustrate existing
bathymetric conditions.
SAV surveying consisted of a cursory analysis of SAV throughout the Study Area
followed by a detailed survey along predetermined transects. The detailed surveyed
involved establishing and reviewing conditions along a series of transects and shallow
water diving at each of the sampling stations to fully understand the extent and coverage
of any SAV resource within the Study Area . At each sampling station, water depth,
substrate type, and SAV identification was performed and recorded. An outboard
powered skiff was used for navigation, mapping and a general base of operations. After
the initial reconnaissance, survey grade GPS was used to navigate along each pre-
established sampling transect to each of the sampling stations. At each sampling
station, a 1.0-meter x 1.0-meter PVC quadrat (with holes so that it sinks) was
haphazardly tossed' into the water. This was done in triplicate at each sampling station
for statistical analysis of the total cover and species of SAV throughout the Study Area (if
any SAV was identified). Sampling/observation of the substrate was performed by
experienced environmental scientists while executing multiple free dives, while the other
workers collected field data, navigated the boat, and viewed and analyzed bottom
samples periodically (sediment and SAV; if present).
1 Haphazardly tossed is a term used to indicate that the quadrat was not systematically placed in
a location that was observed prior to the quadrat lying on the substrate.

July 13t", 2017 SAV Survey
Cape Currituck, Powells Point, Currituck County, NC
In general, the following information was recorded at each sampling station along the
transects; as shown on the attached Exhibit B:
■ An estimate of aerial coverage for all species combined within a square meter
quadrat (rounded to the nearest five percent); this method of estimating aerial
coverage is somewhat standardized and is in use by many SAV investigators.
The method is comparable to the graphic pages included in Munsell® soil color
charts used by wetland scientists in estimating the distribution of mottles in a soil
profile;
■ An estimate of aerial coverage (expressed as a percent) for each individual
species within each quadrat (rounded to the nearest five percent)2;
■ A qualitative description of the substrate type;
■ A depth measurement at each sample station, using survey grade GPS
III. Findings and Observations
On July 13th, 2017 the winds were 10-15 miles per hour, with stronger gusts, from the
south-southwest. Wind tide and precipitation rates resulted in near Normal Water Level
(NWL) conditions for the Study Area; evidenced by wrack lines, beach shelving and
water marks on cypress trees and marsh grass.
In all areas evaluated (during the initial reconnaissance and during the triplicate bottom
sampling at each of the 61 sampling stations), there was no rooted SAV encountered,
nor were there any rhizomes present in any of the bottom samples analyzed. Water
depths collected at each of the sampling stations are plotted on Exhibit B (all depths
relative to NWL). Included as Exhibit C is a spreadsheet that includes sampling station
coordinates, depths and SAV coverage.
The only evidence of SAV in this area included sparse ripped up grass found along the
beach as wrack and drifting at the water surface and in the water column. The ripped up
SAV appeared to include Myriophyllum spicatum (Eurasian Watermilfoil), Valisneria
americans (Wild Celery) and Ruppia maritima (Widgeon Grass). This suggests possible
rooted SAV in other nearby areas where habitat is more compatible for SAV growth.
These species are a common occurrence in the Albemarle estuarine system and
extensive grass beds are known to exist both north and south of the Study Area.
The substrate type throughout the Study Area is best described as a veneer of sand
overlying clays, peat and clayey sands. Near shore areas exhibit a thinning sand profile
overlying relic peat beds with scattered stumps and wood debris originating from the
eroding shoreline. There were also small gravel beds found in some locations along the
shoreline/near shore areas. Some small areas of exposed clay were found just past the
areas of peat in the near shore. The sand bottom in the offshore area was highly rippled
and aligned parallel to the shore by prevailing current and wind direction. There are
some large-scale bars and troughs that are visible in aerial photography and evident
from water depth soundings (See attached Exhibit B).
2 Please note that our findings did not include any SAV, so species composition was not
applicable in this case. In the event that SAV was encountered, data collected at each sampling
station would have been averaged together since sampling was done in triplicate in the vicinity of
each station.

IV. DISCUSSION and CONCLUSION
The findings of this study indicate that the Study Area does not support SAV growth and
is not likely SAV Habitat. High energy, shifting sands, and low visibility/high turbidity
combine to make the Study Area inhospitable to SAV growth.
This survey work was completed before any significant tropical storm systems affected
our area. It should also be noted that Quible scientists reviewed two known SAV areas
nearby and confirmed that regionally, SAV growth seems to be near -normal for the
Upper Albemarle/North River system during the summer of 2017.

No
Ground Surface Condition/Vegetation Condition — assessment area condition metric
Check a box in each column. Consider alteration to the ground surface (GS) in the assessment area and vegetation structure
(VS) in the assessment area. Compare to reference wetland if applicable (see User Manual). If a reference is not applicable,
then rate the assessment area based on evidence of an effect.
GS VS
A A Not severely altered
B B Severely altered over a majority of the assessment area (ground surface alteration examples: vehicle tracks, excessive
sedimentation, fire -plow lanes, skidder tracks, bedding, fill, soil compaction, obvious pollutants) (vegetation structure
alteration examples: mechanical disturbance, herbicides, salt intrusion [where appropriate], exotic species, grazing,
less diversity [if appropriate], hydrologic alteration)
2. Surface and Sub -Surface Storage Capacity and Duration — assessment area condition metric
Check a box in each column. Consider surface storage capacity and duration (Surf) and sub -surface storage capacity and
duration (Sub). Consider both increase and decrease in hydrology. Refer to the current NRCS lateral effect of ditching guidance for
North Carolina hydric soils (see USACE Wilmington District website) for the zone of influence of ditches in hydric soils. A ditch
<_ 1 foot deep is considered to affect surface water only, while a ditch > 1 foot deep is expected to affect both surface and ditch
sub -surface water. Consider tidal flooding regime, if applicable.
Surf Sub
F,A F,'A Water storage capacity and duration are not altered.
B B Water storage capacity or duration are altered, but not substantially (typically, not sufficient to change vegetation).
C C Water storage capacity or duration are substantially altered (typically, alteration sufficient to result in vegetation
change) (examples: draining, flooding, soil compaction, filling, excessive sedimentation, underground utility lines).
3. Water Storage/Surface Relief— assessment area/wetland type condition metric (answer for non -marsh wetlands only)
Check a box in each column for each group below. Select the appropriate storage for the assessment area (AA) and the wetland
type (WT).
AA WT
3a. MA MA Majority of wetland with depressions able to pond water > 1 foot deep
B B Majority of wetland with depressions able to pond water 6 inches to 1 foot deep
C C Majority of wetland with depressions able to pond water 3 to 6 inches deep
D D Depressions able to pond water < 3 inches deep
3b. FA Evidence that maximum depth of inundation is greater than 2 feet
B Evidence that maximum depth of inundation is between 1 and 2 feet
C Evidence that maximum depth of inundation is less than 1 foot

4. Soil Texture/Structure — assessment area condition metric
Check a box from each of the three soil property groups below. Dig soil profile in the dominant assessment area landscape
feature. Make soil observations within the 12 inches. Use most recent National Technical Committee for Hydric Soils guidance for
regional indicators.
4a. rA Sandy soil
r, B Loamy or clayey soils exhibiting redoximorphic features (concentrations, depletions, or rhizospheres)

5. Discharge into Wetland —opportunity metric
Check a box in each column. Consider surface pollutants or discharges (Surf) and sub -surface pollutants or discharges (Sub).
Examples of sub -surface discharges include presence of nearby septic tank, underground storage tank (UST), etc.
Surf Sub
F,A F,'A Little or no evidence of pollutants or discharges entering the assessment area
B K—,B Noticeable evidence of pollutants or discharges entering the wetland and stressing, but not overwhelming the
treatment capacity of the assessment area
C jC Noticeable evidence of pollutants or discharges (pathogen, particulate, or soluble) entering the assessment area and
potentially overwhelming the treatment capacity of the wetland (water discoloration, dead vegetation, excessive
sedimentation, odor)
6. Land Use — opportunity metric
Check all that apply (at least one box in each column). Evaluation involves a GIS effort with field adjustment. Consider sources
draining to assessment area within entire upstream watershed (WS), within 5 miles and within the watershed draining to the
assessment area (5M), and within 2 miles and within the watershed draining to the assessment area (2M). Effective riparian buffers
are considered to be 50 feet wide in the Coastal Plain and Piedmont ecoregions and 30 feet wide in the Blue Ridge Mountains ecoregion.
WS 5M 2M
F A r A F A >_ 10% impervious surfaces
P B r7l B r B < 10% impervious surfaces
F C F C r C Confined animal operations (or other local, concentrated source of pollutants)
F D r D F D >_ 20% coverage of pasture
F E r E r E >_ 20% coverage of agricultural land (regularly plowed land)
F F F F r F >_ 20% coverage of maintained grass/herb
F G r G F G >_ 20% coverage of clear-cut land
F H H r H Little or no opportunity to improve water quality. Lack of opportunity may result from hydrologic alterations
that prevent drainage or overbank flow from affecting the assessment area.
Wetland Acting as Vegetated Buffer— assessment area/wetland complex condition metric
7a. Is assessment area within 50 feet of a tributary or other open water?
Yes [—,No If Yes, continue to 7b. If No, skip to Metric 8.
Wetland buffer need only be present on one side of the water body. Make buffer judgment based on the average width of the wetland.
Record a note if a portion of the buffer has been removed or disturbed.
7b. How much of the first 50 feet from the bank is weltand? Descriptor E should be selected if ditches effectively bypass the buffer.
A >_ 50 feet
B From 30 to < 50 feet
C From 15 to < 30 feet
D From 5 to < 15 feet
E < 5 feet or buffer bypassed by ditches
7c. Tributary width. If the tributary is anastomosed, combine widths of channels/braids for a total width.
<_ 15-feet wide r-, > 15-feet wide F,' Other open water (no tributary present)
7d. Do roots of assessment area vegetation extend into the bank of the tributary/open water?
Yes r," No
7e. Is tributary or other open water sheltered or exposed?
r, Sheltered — adjacent open water with width < 2500 feet and no regular boat traffic.
K: Exposed — adjacent open water with width >_ 2500 feet or regular boat traffic.
8. Wetland Width at the Assessment Area — wetland type/wetland complex metric (evaluate for riparian wetlands only)

Size —wetland type/wetland complex condition metric
Check a box in each column. Involves a GIS effort with field adjustment. This metric evaluates three aspects of the wetland area: the
size
of the wetland type (WT), the size of the wetland complex (WC), and the size of the forested wetland (FW) (if applicable, see User
Manual). See the User Manual for boundaries of these evaluation areas. If assessment area is clear-cut, select "K' for the FW column.

EYes F,' No Wetland type has a surface hydrology connection to open waters/stream or tidal wetlands.
14. Edge Effect — wetland type condition metric (skip for all marshes)
May
involve a GIS effort with field adjustment. Estimate distance from wetland type boundary to artificial edges. Artificial edges include
non -forested areas >_ 40 feet wide such as fields, development, roads, regularly maintained utility line corridors and clear -cuts.
Consider the eight main points of the compass.
oA
No artificial edge within 150 feet in all directions
EB
No artificial edge within 150 feet in four (4) to seven (7) directions
.,C
An artificial edge occurs within 150 feet in more than four (4) directions or assessment area is clear-cut
15. Vegetative Composition —assessment area condition metric (skip for all marshes and Pine Flat)
EA Vegetation is close to reference condition in species present and their proportions. Lower strata composed of appropriate
species, with exotic plants absent or sparse within the assessment area.
B Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species
characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or
clearing. It also includes communities with exotics present, but not dominant, over a large portion of the expected strata.
C Vegetation severely altered from reference in composition. Expected species are unnaturally absent (planted stands of non -
characteristic species or at least one stratum inappropriately composed of a single species). Exotic species are dominant in
at least one stratum.
16. Vegetative Diversity — assessment area condition metric (evaluate for Non -tidal Freshwater Marsh only)
EA Vegetation diversity is high and is composed primarily of native species (<10% cover of exotics).
r,'B Vegetation diversity is low or has > 10% to 50% cover of exotics.
oC Vegetation is dominated by exotic species (>50% cover of exotics).

17. Vegetative Structure — assessment area/wetland type condition metric
17a. Is vegetation present?
r: Yes C; No If Yes, continue to 17b. If No, skip to Metric 18.

Powells Point Harbor January 23, 2024
Resort Marina Development
NC DCM CAMA Major Permit
I. INTRODUCTION
The site consists of two parcels of land (totaling 120.15 acres by survey) located adjacent to the
Kilmarlic Golf Club/Residential Community and the Albemarle Sound (Attachment A -Relevant
Portion of the USGS Topographic Quadrangle -Point Harbor, with Site Identified).
In 2008, Currituck County approved a conceptual development plan for the Cape Currituck
Marina (now referred to as Powells Point Harbor) community. Due to the recession, the
development never progressed.
A CAMA Major Permit for the proposed development was accepted as complete on December
1, 2023, by NC DEQ Division of Coastal Management. The permit was withdrawn by the
applicant on December 12, 2023.
Powells Point Harbor, as shown on the attached Figure 1 (CAMA Major Permit Plans- Sheets
1-4), received zoning approval by the Currituck County Board of Commissioners (see
Attachment B-February 18, 2019, Minutes) and a flushing model was performed and accepted
by the North Carolina Division of Water Resources (Attachment C). Please note, the approved
and proposed Marina Resort Concept is an overall reduction in residential units (237 to 160
units) and total wetlands impacts from earlier concepts.
The applicant will be required to seek a Special Use Permit from the Currituck County Board of
Commissioners for the proposed marina as shown on the attached Figure 1. The Special Use
Permit would contain language that regulates the operation of the marina and proposed aeration
system to ensure that the aeration system is maintained for the life of the marina. This concept
has been discussed with DWR, the applicant and Currituck County. The applicant is seeking
approval of the CAMA Major Permit and would then work with DWR and Currituck County to
draft an acceptable monitoring and maintenance plan of the aeration system that would be
included in the conditions of the Special Use Permit.
II. EXISTING CONDITIONS
The property is a mix of wetlands with approximately 20 acres of uplands surrounding an
existing reclaimed sand mine which is known as the Broadhead Pit. There are approximately
1,800 linear feet of shoreline located within the Project Area. There are two major wetland
types found on Site, Riverine Swamp Forest, and Salt/Brackish Marsh (NC WAM). A large
swath of Salt/Brackish Marsh (+/- 42 Acres) has been overtaken by Phragmites australis that
likely gained a foothold during mining and canal digging that occurred on the property in the
past (1970's). At one time in the past, there was a connection of interior canals to the
Albemarle Sound —this is still reflected on the USGS topographic maps and can be seen on the
historical aerial photographs. Today, the interior wetlands are not directly connected to the
Sound due to natural sand berms that have formed along the shoreline. However, during
tropical storms, over wash has been observed in the marsh indicating that at times, water from
the Sound is pushed into the wetlands. During normal water and low wind tide events, we have
observed water from the interior wetlands seeping through the shoreline into the Sound.
Uplands on Site are maintained grasses, pines, and unimproved paths and roads. There is a
single-family residential home on the property along with horse barns and paddocks. A large,
10-acre lake that was a historic borrow pit constructed in the 1970's is located on the property.
Prior to the 1970's, the Site was agricultural fields. Historical aerial photographs of the property
dating back to 1952 are included as Attachment D.
III. PROPOSED WORK
The applicant proposes to construct a marina resort style community with a mix of single-family
residences, townhomes, condominiums, and supporting light commercial around the existing

Powells Point Harbor
Resort Marina Development
NC DCM CAMA Major Permit
January 23, 2024
10-acre lake, which is proposed to be connected to the Albemarle Sound via a 60 feet wide 8.0
feet deep navigation channel excavated through Phragmites australis.
The creation of the marina involves connecting the existing lake (boat basin) to the Albemarle
Sound via a canal through existing Phragmites dominated non -coastal wetlands. The existing
lake has water depths that are deeper than the proposed connecting water depths of -8.0 feet
(relative to NWL). Therefore, the lake bottom will be filled with clean sandy material and
regraded to depths of -8.0 ft (NWL) using sands from proposed dredging and if needed, a local
source to match the proposed connecting water depths in the Albemarle.
The proposed canal will be excavated through Phragmites dominated non -coastal wetlands
measuring 1,257 linear feet in length (centerline) with a total width of 60 feet to a depth of -8.0
feet (NWL) out into the Albemarle. Proposed impacts to wetland habitats from the creation of
the upland marina basin are:
• 48,709 square feet of Phragmites dominated non -coastal wetlands,
• 15,278 square feet of open water ponds within the non -coastal wetlands complex, and
• 31,617 square feet of uplands
Total impacts to wetlands/open ponds under the proposed channel alignment equal 65,740.4
square feet or 1.51 acres. The canal cut will also impact 31,617 square feet of uplands. Two
bulkheads measuring 251 and 213 linear feet are proposed along the upland section of the
channel cut to stabilize the channel entrance to the basin. A 1,674 linear feet and 60 feet wide
channel will extend from the shoreline to an existing water depth of -8.0 feet NWL, equaling
100,440 square feet (2.3 acres) of open water impacts.

area of the various habitats found on the property have been included as Figure 1. Two slotted
breakwaters are proposed to run along both sides of the canal cut through wetlands to the
Albemarle (due to the angle of the proposed canal, the northern edge of the canal would
measure 1,256 liner feet and the southern edge would measure 1,244 linear feet through
Phragmites dominated wetlands). These breakwaters are proposed to help stabilize the
channel, dissipate wave and boat wake energy, and allow water to flow into and out of the
adjacent wetlands. At the mouth of the channel connecting to the Albemarle, two 150 linear feet
jetties are proposed along with shorter tapering jetties as shown on the attached CAMA Major
Permit Plan. The jetties would taper from the 150 If at the channel to 80 and 55 linear feet. This
three jetty system is proposed to limit the near shore sediment transport and limit channel
dredge maintenance.
Two bulkheads measuring 251 and 213 linear feet are proposed along the upland section of the
channel cut to stabilize the channel entrance to the basin. The basin edge will not be
bulkheaded and the 30 feet buffer would be left in a natural state.
166 total boat slips with accompanying piers and finger piers are proposed. This would allow
one slip for each residence in the community and six large slips for transient use. A total of 12
docks are proposed and include (see corresponding dock numbers on the attached full sized
(24" x 36") Site Plans):
(1) 141 If by 8 ft floating dock with one 5 If access pier,
(2) 145 If by 8 ft floating dock with 5 If access pier.
(3) 123 If by 8 ft floating dock with one 75 If access pier,
(4) 340 If by 8 ft floating dock with two 6 If access piers,
(5) 119 If by 8 ft floating dock,

(6) 326 If by 8 ft floating dock with two 8 If access piers,
(7) 160 If by 8 ft floating dock with one 8 If access pier,
(8) 160 If by 8ft floating pier,
(9) 558 If by 10 ft floating dock with fueling facilities,
(10) 396 If by 8 ft floating dock with three 8 If access piers,
(11) 177 If by 8 ft floating dock with one 10 If access pier,
(12) 450 If by 6 ft pier with 50 If by 20 ft platform
A total of 122 floating finger piers are proposed including:
• (34) 12 If by 3 ft
• (81) 20 If by 3 ft
• (7) 25 If by 3 ft
Fueling facilities are proposed along Dock 9. Two dispensers are proposed along the dock with
a fuel line connecting to two underground storage tanks (USTs) located under the proposed
parking area adjacent to the boat ramp and docking facility. Sewage pump -out will be offered for
the marina. The pump out will be connected to the proposed wastewater treatment facility that
would service the community. "No Overboard Discharge/Sewage Pump out Available" signs will
be placed on each of the 12 docking facilities in visible locations.
A public boat ramp is proposed to be constructed adjacent to the proposed restaurant. The
concrete ramp will be poured and cured on land and placed into the water once the concrete is
dry. No live concrete will be poured below NWL. A 2,518 If by 6 ft wide wooden boardwalk with
13 accessways (varying from 15-36.5 ft), and elevated 3 ft above wetland substrate, is proposed
to wrap around the basin to offer pedestrian access to the various piers and slips around the
marina. The boardwalk will be constructed along the shoreline over wetlands, but not over the
water. A total of 1,265 sf of the accessways will be over uplands. The shoreline of the basin will
not be hardened and a natural emergent wetland vegetated shelf around the basin will be
maintained and promoted. A 105 If bulkhead with two 20 LF wingwalls, is proposed to stabilize
the area in front of the proposed restaurant.
Proposed development includes construction of up to 160 total residential units and all required
and associated infrastructure. Residential units will be a mix of townhomes, condominiums, and
single-family units. The proposed marina community includes a ship's store, light retail and a
restaurant.
An existing soil road that extends from West Side Lane across the property to the northwest is a
deeded easement and sole point of access to the adjacent property to the northwest. This
existing soil road is proposed to be improved with gravel and widened to meet minimum
standards for emergency vehicle access and provide access to the adjacent property and the
proposed wastewater treatment plant. Based on a review of historic aerial photography and
USGS topographic maps, this road has been in use since the 1940's and currently crosses a
man-made canal (dug in the 1970's), which appears to have been dug in what was once a
natural water course.
The road leading to the proposed wastewater treatment plant needs to be widened to provide
the minimum required drive aisle widths (20 feet minimum) for emergency vehicles and
improved with gravel to provide the required all-weather driving surface suitable for emergency
vehicles and fire trucks and provide the County required pedestrian access (see Attachment B-
Approval Minutes from Currituck County BOC). A 722 LF pedestrian walkway is also proposed
along the north side of the gravel improved road. This walkway will be timber and will not cross
Waters of the US.

The existing culvert is only 32 inches in diameter and is angled incorrectly and in poor condition.
This undersized and damaged culvert does not provide adequate circulation and aquatic
passage. A new 60-inch culvert is proposed to replace the existing culvert and will be buried a
minimum of one foot below the existing canal substrate. All proposed development is shown on
the attached Figure 1- CAMA Major Permit Plan.
IV. PURPOSE AND NEED
The purpose of the proposed project is to develop a resort marina community providing deep
water access to the Albemarle Sound and Atlantic Intracoastal Waterway (AIW) from the west
side of Currituck County. Currituck County does not currently have a resort waterfront
development with deep water access suitable for sailboats and larger vessels using the AIW on
the Albemarle Sound.
The property where the proposed development is located is currently listed as "Full Service" by
Currituck County's Land Use Plan. Destination resort style development with opportunities for
short term rentals fits the County's Economic Development goals for Lower Currituck, and the
project as proposed would offer opportunities for transient vessels, time shares, short term
rentals and access to area amenities (golf courses, area beaches, deep water marina,
waterpark) as well as providing permanent deep -water access to the Albemarle Sound. This
location also has the potential to tie into the proposed Inner Banks Ferry System.
V. ALTERNATIVES ANALYSIS
A total of eight development options (including No Development and Alternate Sites Analyses)
have been considered for this project and each of the options are discussed in detail below.
A. 2008 County Approved Master Plan (Original Concept)

2. The 2008 Approved Master Plan (County Master Plan Approved 2008) option considers a boat channel with
three 90 d. turns which is not allowed per 15A NCAC 07H .0208 (b) (1) (G) .
3. Wetlands dominated by P. australis.
4. 2008 developer preferred option channel depth -5.0 NWL: not feasible for Proposed Project Purpose and
Need.
It should be noted that the 2008 Approved Master Plan (County Master Plan Approved
2008) option considered a boat channel with 90 degree turns which is not allowed per
15A NCAC 07H .0208 (b) (1) (G), and the proposed depths were -5.0 feet relative to
normal water level. These depths and sharp turns would not accommodate the types of
vessels that the current marina is designed to attract, and this option is dismissed from
further consideration. An amended Master Plan was approved by the Board of
Commissioners on February 18, 2019.

E. No Development Option
If the property is not developed as proposed, it is likely that at some point in the future
the property would be developed as multi -family or single-family home sites. An 18-
home cottage community was developed adjacent to Kilmarlic along Highway 158 in
recent years. This 18-home community is geared towards rentals and supporting the
golf community, and the units are fully rented or sold with new housing starts underway.
West Side Resorts LLC now owns the property and intends to develop it; therefore, the
No Development Option is not viable.
F. Open Water Marina Option
An open water marina could be proposed on this property as there is upland access
(albeit narrow) to the Albemarle Sound. The goal of the proposed development is to
attract users of the Intracoastal Waterway (AIW), sailboats and a mix of open runabout
type of boats. An open water marina would require dredging to provide adequate
water depths or would need to be placed 1,600 feet out into the Sound (distance from
shore to -8.0 water depths: relative to NWL). This distance, plus the distance to upland -
based infrastructure to support the desired mixture of boats would put the mooring field
nearly one-half mile from the proposed development. This option is not feasible, in

Powells Point Harbor

terms of cost (strictly analyzed in terms of distance to extend utilities) and acreage of
Public Trust Capture (Public Usurpation) required to meet the Purpose and Need of the
proposed development. If an open water marina was proposed to be sited adjacent to
the shoreline, a large area of dredging would be required to achieve the desired depths
to accommodate boats from the AIW and this could result in usurpation of
approximately 7.5 Acres of Public Trust Waters. A comparison of impacts associated
with the Open Water Marina Option compared to the Developer Preferred Option are as
follows:

2. Salt/Brackish Marsh dominated by Phragmites australis.
Given the impacts to Public Trust and the distances between the marina resort
development, the Open Water Marina Option is not viable and is not considered further.
G. Conveyor Belt/Mechanical Lift Marina Option
This option would involve the construction of a lift or conveyor belt apparatus that would
accept a boat out in the open water of the Albemarle Sound and transport vessels 1,300
feet (would still need to dredge the open water channel) over wetlands and deposit the
boat into the existing on -site lake. This development option has been considered briefly
and would not be a feasible option for the types of boats (large AIW yachts and
sailboats) that the marina is designed to attract. This option is not viable and is not being
considered further.
H. Residential Development -No Marina
Without a marina, the property may be developed as residential property. Due to the
proximity to a golf course, Albemarle Sound and the Outer Banks beaches, land in this
location is valued relatively highly. A high -end resort style development coupled with a
marina (unique to Currituck County) is likely the highest and best use of the property.
The developer is relying on the construction of a marina to drive the demand for the 160
units as shown on the housing component of the proposed development. Currituck
County and Kilmarlic have a large inventory of undeveloped properties with frontage on
golf courses, lakes, and Albemarle Sound. The County was only willing to allow for the
development of up to 50 total units (or less) if the marina is not able to be permitted in
the 2019 Board of Commissioners hearing and approval.
The current development plan is backed by investors that desire to create a marina
community with access to the Albemarle Sound, which would be unique in Currituck
County. Given the current inventory of similar properties with proximity to golf and
lakes in lower Currituck, residential development without a marina would not be a viable
option for the developer.

I. Off Site Development Considerations
There are Sites along the Albemarle Sound and North River with the potential to be
developed into upland harbors by virtue of waterfront access and uplands that extend to
the shoreline of the Albemarle.
One potential Site is located north of the selected Project Area on a property formerly
known as the Webber Tract. This property was the subject of several feasibility
sketches and concept plans back in the mid to late 2000's. Like much of the North River
and Upper Albemarle coastline along Currituck County, the shoreline and shallow water
areas adjacent to this property have large expanses of Submerged Aquatic Vegetation
(SAV) beds and are therefore Essential Fish Habitat.
Another property with sound frontage (and currently up for sale) owned by the Griggs
family is located just south of the proposed Project. This property has uplands that
adjoin the shoreline, but there is a history of unauthorized wetlands impacts, and SAV
resources have been observed along the shoreline. The Griggs property is listed for
sale, is much larger, and the price per acre is significantly higher than the Powells Point
Harbor property. The Griggs property may support a small marina development concept
in the future, but given the high cost, Conservation Zoning, large expanse of Juncus
marsh with minimal upland connection, presence of SAV and EFH, and history of
unauthorized wetlands impacts, this property does not appear to be a viable alternative.
There do not appear to be any other properties on the western shore of the Currituck
Peninsula that offer the opportunity that the Powells Point Harbor property has in terms
of being able to connect an existing lake to the Albemarle and support vessels using the
AI W.
VI. AVOIDANCE AND MINIMIZATION
The proposed marina development has been designed to promote flushing to the maximum
extent practicable, while limiting impacts to wetlands and shallow water habitat by selecting a
channel through Phragmites wetlands and to a connecting water depth of -8.0 feet relative to
NWL. The developer wanted a total depth of -10.0 feet NWL, but this depth has been reduced
to lessen channel length, decrease public trust impacts and avoid lower dissolved oxygen (DO)
waters (found to occur at deeper depths in the Albemarle during summer months). The uplands
development proposes a total of 160 units (originally approved for 237 units), 166 wet boat slips
and light commercial to serve the development, marina and surrounding community. The
preferred development option provides an additional 30 feet buffer from natural wetlands (as
required by County regulations). The development will be served by a central wastewater
treatment system with disposal proposed to go on the adjacent golf course. A force main and
pump stations will be used to service all of the development, as well as the pump out available
to the marina, and be routed to a wastewater treatment facility on the northeast side of the
property. All clean effluent from the treatment facility will be routed onto the adjacent golf course
to a pre -approved area. The full design of the wastewater system will be contingent upon
approval for a CAMA Major Permit. The wastewater treatment plant and disposal area would be
permitted through the NC DEQ DWR.
Please note, the existing lake (proposed basin) was created out of agricultural lands (see
historic aerial photography). Fringe wetlands have naturalized around the lake, but these
wetlands appear to be the result of the Mine Reclamation activities/attempts after the mine was
decommissioned. As proposed, the total wetland fill impacts for the upland development are
0.48 acres; which includes filling for road crossings and upland fill to achieve the proposed
density (160 units; down from 237 units), provide adequate stormwater management and

provide for all appropriate setbacks. Impacts from the channel creation are limited to 1.51 acres
by limiting the channel width to 60 feet. The channel orientation is the most direct route to the
Albemarle Sound that avoids natural wetlands that have not been overrun with Phragmites, and
also avoids the need to remove mature cypress and other higher value trees and wetland
habitats. The selected channel orientation is the result of years of planning and discussing with
regulatory and permitting agencies through a series of scoping meetings.
The project has been designed to avoid and minimize impacts to natural wetlands. All resource
agency (USFWS, NOAA, NC WRC, DWR, and NC Fisheries) recommendations guidance would
be followed during construction activities.
VII. THREATENED AND ENDANGERED SPECIES CONSIDERATION
United States Fish and Wildlife (US FWS) Biologist, Kathryn Matthews was contacted via email
and telephone on June 19, 2018, to discuss the proposed project and impacts to threatened and
endangered species. Ms. Matthews indicated that USQUARE FEETWS will coordinate directly
with the USACE as required under Section 7 of Endangered Species Act. On January 19,
2024, Quible queried the USFWS Information for Planning and Consultation (IPaC) website and
entered the project location. IPaC generated a list of species (referred to as trust resources)
and are included as Attachment E. This list is included as a reference and not intended to be
considered for Consultation. However, Quible used this list and previous information from
USFWS and other resource agencies to assist in the location and design of the proposed
development.
Threatened, Proposed Endangered and Endangered mammals listed as potentially affected by
activities in the proposed project area include West Indian Manatee's, Northern Long Eared
Bats and Tricolored Bats. However, the project area is not considered critical habitat for these
species or critical habitat has not been designated. The USFWS will coordinate directly with the
USACE as required under Section 7 of the Endangered Species Act.
Threatened, and Endangered bird species listed as potentially affected by activities in the
proposed project area include the Eastern Black Rail, Piping Plover, Red -cockaded
Woodpecker and Rufa Red Knot. The proposed project area does not overlap with critical
habitat for the Piping Plover and no critical habitat has been designated for the Eastern Black
Rail. A review of the proposed critical habitat found in Federal Register Vol. 86 No. 133 reveals
that the proposed project is not critical habitat for this species. Therefore, the proposed project
would not likely have an adverse impact on any listed Threatened or Endangered species. The
USFWS will coordinate directly with the USACE as required under Section 7 of the Endangered
Species Act.
Threatened and Endangered reptile species listed as potentially affected by activities in the
proposed project area include American Alligator, Green Sea Turtle, Kemps Ridley Sea Turtle
Leatherback Sea Turtle, and Loggerhead Sea Turtle. However, the project area is not
considered critical habitat for these species or critical habitat has not been designated. The
USFWS will coordinate directly with the USACE as required under Section 7 of the Endangered
Species Act.
No bald eagle nests have been spotted on the property. However, bald eagles do frequent the
shoreline and eagles have been seen on the property on several occasions. Bald Eagles are
common in Lower Currituck and along the shoreline of the Albemarle, especially in the winter
months (after Osprey migration). According to Ms. Matthews in 2018, there were no Northern
Long Eared Bat roosts near the Site, but this information will need to be updated during the ESA
process. Atlantic Sturgeon are known to inhabit the waters of the Albemarle. All in -water

construction would be performed conventionally, and in a manner that allows for the passage of
fish and in accordance with any required mitigation plan.
Proposed work (as currently planned) would involve in -water construction of a marina and all
associated infrastructure. All appropriate USQUARE FEETWS guidance will be followed during
construction (Manatee, Sturgeon etc.). Jetties and breakwaters are proposed to protect the
channel from filling in seasonally and during larger storm events limiting maintenance dredge
requirements. In addition, the channel through the Phragmites wetlands will have a breakwater
(with slots at one inch for every foot of wall) to eliminate boat wake. General construction
activities in waters used by the West Indian Manatee are required to follow mitigation guidance
provided by USQUARE FEETWS.
Vill. FLUSHING MODEL
Several flushing models have been constructed, analyzed and provided to the NC DEQ Division
of Water Resources (DWR) for the Proposed Project. DWR indicated in a letter dated March
26, 2020, that the original model was valid and appropriate to reference during the permitting
process. After a statistical analysis, the model results indicate that no more than 10 percent of
the depth averaged dissolved oxygen concentrations at a given location are below 5mg/L over
the 87-day model run time. Copies of the flushing model narratives and memorandums and all
associated correspondence, including the March 26, 2020, letter from DWR indicating that the
flushing model is valid and is appropriate to reference in the application process is included as
Attachment C (Flushing Model Documentation). Flushing model files have been submitted
directly to DWR for review.
A CAMA Major Permit was submitted and accepted as complete on December 1, 2022. In
response to the CAMA Major Permit application, DWR issued a Request for Additional
Information (RFI) on February 13, 2023. The RFI placed a hold on the CAMA Permit application
and requested that the applicant "...revise your plan to comply with the recommended flushing
times provided in guidance documents". In response to the DWR RFI, additional modeling was
performed by Dr. Chris Reed and submitted to DWR along with responses to other requests on
November 20, 2023. The additional modeling included exploring changes to the marina layout
by adding a "flow through channel' and also looking at variables within the accepted model to
better understand where changes could be made to improve dissolved oxygen concentrations.
The additional modeling did not yield any better results than the originally submitted flushing
model and marina layout. Therefore, the proposed basin and channel configuration is the best
possible layout for water quality.
After a series of meetings with DWR, it was determined that aeration could be proposed as a
method to ensure that the marina meets the dissolved oxygen requirements of 5 mg/L at all
times. The marina flushing model (without aeration) predicted that there would be instances
during the warmest months of the year where predicted DO levels would be slightly below the
5mg/L threshold in 20% of the cells 10% of the model run time of 87 days. Statistical analyses
of the original "accepted model' are presented in the Statistical Analysis memorandum included
in Attachment C.
In response to DWRs RFI, an additional model was created using aeration. The "aeration"
flushing model was submitted to DWR on November 20, 2023, for review and approval. The
aeration model predicts that DO for the marina would be at or above 5mg/L at all times by
adding 475 kg/day of DO to the basin. The preferred method for achieving this would be
through the use of a diffused aeration system. All flushing model files have been submitted
directly to DWR. Summaries and narratives of the flushing models along with additional
information about the proposed diffuse aeration system are included in Attachment C.

The results of the flushing model and predicted aeration volumes were forwarded to SOLitude
Lake Management (SOLitude) for review and design and specification of a diffused aeration
system. SOLitude provided technical guidance for the type of system, optimal diffuser head
locations and also pricing for the system. Technical information related to the proposed
aeration system along with system pricing is included in Attachment C. Please note, the costs
for the diffuser aeration system and installation are approximately and only $32,224.00.
Based on the results of the flushing model and input from SOLitude, 12 aeration heads are
proposed to be placed around the marina as shown on the attached Figure 1. Air would be
pumped through tubing to the submerged heads at a predicted and modeled rate of 475 kg/day.
The applicant proposes to monitor dissolved oxygen within the marina basin and channel on a
monthly basis with weekly monitoring during June, July, August, and September (warmest four
months of the year). A monitoring plan and proposed monitoring locations are included in
Attachment F. Monitoring of DO would be performed to ensure DO concentrations are as
predicted in the modeling and allow the marina operator to adjust the diffused aeration system
to optimize DO levels in the marina.
IX. ESSENTIAL FISH HABITAT/SAV ASSESSMENT
An Essential Fish Habitat Assessment (EFH) was prepared for the project area (Attachment
G). The EFH Analysis includes a report of findings for an SAV Survey that was conducted in
July of 2018. NC DCM/DMF Staff concurred with the findings in the SAV Report (no habitat
observed in 2018 and none reported during the collection of water quality data for flushing
model 2019). An updated SAV survey was conducted on August 1st, 2022, within the proposed
channel alignment. This updated SAV report is also included in Attachment G.
X. STATE HISTORIC PRESERVATION OFFICE CONSULTATION
On June 4, 2018, a letter was mailed to Ms. Renee Gledhill -Earley with the North Carolina
Department of Cultural Resources (DCR) State Historic Preservation Office (SHPO). The letter
requested any information that SHPO had on file for the project. The SHPO office indicated in a
letter dated July 6, 2018 (ER- 18-1315) that they are not aware of any historic resources which
would be affected by the project as proposed. SHPO correspondence is provided as
Attachment H. There have been no changes to the property or project scope since 2018.
XI. PROPOSED MITIGATION
Mitigation for the proposed project is focused on offsetting habitat loss by making a payment to
an approved wetlands mitigation bank. DWR requested that an NC WAM Wetlands
Assessment Form be completed to justify why the mitigation offered is appropriate for the
project. An NC WAM Wetlands Assessment Form is attached in Attachment I. The project has
an overall wetland rating of "Medium". Please note, during our many scoping meetings, the
applicant was specifically directed to offer mitigation bank payments as proposed mitigation for
project impacts. Proposed project impacts and mitigation include:
Dredge of the channel through Phragmites dominated wetlands-1.509 acres) —the
wetlands that are proposed to be impacted are not considered coastal wetlands.
2. Fill of Non -Riparian wetlands for upland development (0.48 acres)
12

Powells Point Harbor
Resort Marina Development
NC DCM CAMA Major Permit
January 23, 2024
Proposed mitigation for the unavoidable impacts necessary to create an upland marina basin
and resort community at this location is payment into the Great Dismal Swamp Restoration
Bank (GDSRB) at a ratio of —2:1 (credits to impacts). This would result in a payment into a
wetlands mitigation bank for 3 acres of riparian wetlands and approximately 0.96 acres of non -
riparian wetlands credits. Wetlands credits availability letters are included as Attachment I
XII. DWR Certification
The proposed proponent hereby certifies that all information contained herein is true, accurate,
and complete to the best of my knowledge and belief. The project proponent hereby requests
that the certifying authority review and take action on this CWA 401 certification request within
the applicable reasonable period of time. A scoping meeting was held on January 91", 2019, and
DWR was present. The scope of the project has not changed since this scoping meeting.
