G reg,
Lance and I have reviewed your email and coordinated with our dredge crew to ensure
when we could move the needed vessels to the project location. Please see Lance's
comments in red below. We are going to start gathering materials and moving vessels
today to work on meeting the April 15t" deadline. Our Dredge Superintendent and the
crew checked the spoil site and it should be able to hold the material needed to be
removed. I have contacted the National Park Service to check for any resources
that may be in the area. The shoal in this channel is changing every day and with
another good hard wind the entrance to Southdock could be completely filled in.
If you need any additional information please let me know.
Thank you,
Catherine Peele

Importance: High
Cat,
To follow up on our phone conversation on the proposed dredging activities at
Southdock Ferry Facility, DCM would like to provide more information on
the processing of this proposed authorization and to request additional
information.
• �JCDOT has the ability to conduct maintenance dredging, with a proper
authorization request, adhering to the current maintenance clause
conditions (specifically, the use of the approved upland spoil disposal site)
with minimal further coordination. At this time DCM would be able to
approve �JCDOTto conduct maintenance dredging until April 15, 2018,
which includes in-water moratorium relief of 14 days. Any additional in-
water work after April 15t" will require additional coordination, and may
not be approved. Placement of spoil material within the approved spoil
site is strongly preferred during the in-water work moratorium. iTJc w111

• The current request is to begin work in the second week of April
2018. Based upon subsequent verbal coordination, it is understood that
�JCDOT anticipates the project duration will be approximately one
month. As you know, the active CAMA Permit 224-87 includes a
moratorium that "�Jo in-water work shall be conducted between April 1 to
September 30 of any year without prior approval of the �J.C. Division of
Coastal Management (DCM), in consultation with the appropriate
resources agencies." ." I tald Cat ane manth due ta the timeframe

• Comments received from the DCM Fisheries Resource Specialist on
6/15/17 emphasize the biological importance of Hatteras Inlet: "Shallow
draft inlet such as Hatteras Inlet support a high diversity of estuarine
species and are the only link for fish and shellfish such as blue crabs to
ingress and egress from the open ocean to the estuarine environment of
the sounds. This movement is dictated by the availability of forage and is
a critical route to the spawning migration of many species. For these
reasons an in-water work moratorium from April 1 to September 30 is
recommended to protect fisheries resources that utilize the inlet system
during the season of highest biological activity." After coordinating
specifically about this proposed project, DCM Fisheries would prefer work
to be completed outside of the fisheries moratorium when possible. The
inlet provides the link between the oceans and the sounds and spawning
grounds for many species including blue crabs which are one of �JC
highest value fisheries resources. Upland disposal would be preferable.
The rapid erosion rates seen in the project area likely reduce the ability for
benthic organism to colonize the intertidal zone of the beach as they
would in a normal oceanfront swash zone. Although concerns over
elevated turbidity levels still exist as current velocities in the area are likely
to sweep away a great deal of sand placed in the area before it can settle
on the beach. Elevated turbidity levels can cause clogging of gills and
reduces visibility negatively impacting feeding, especially of larval fishes.
Delaying the start of the project until the second week of April and
working into May increase the potential for negative impacts to fisheries
resources in the inlet complex. iTJc arc ��1n� t� p�lnp �n thc �plan�

• The current authorization requests states "material that is removed during
this project will placed on along 850 linear feet of beach behind the
parking lanes "hairpin curve" that is used for the traveling public to be
staged in while waiting to be loaded onto the vessels". Please submit a
drawing that accurately represents the location and boundaries of sand
deposition and specifically state how much material is proposed to be
placed below the high water mark.
NCDOT currently has an active General Permit (#68669) for the
placement of temporary sandbags in order to protect the stacking lanes
("hairpin curve") in the vicinity of the proposed beach deposition.
Typically, temporary sandbags are to protect impenitently threatened
structures and as currently proposed the current authorization request to
deposit sand adjacent to the stacking lanes could categorize the structure
as no longer "impenitently threatened". Will NCDOT still pursue the
temporary sandbags in conjunction with the proposed beach
nourishment? If both projects are to be completed as proposed
simultaneously, please indicate that information. iTJ1th thc rn�rat�rl�rn,

The current authorization request sates "The NCDOT Highway Division 1
has recently acquired permits to remove the broken asphalt, place
sandbags along the curved lanes, and install sheet piling". The General
Permit issued by DCM only authorized the use of temporary sheet pile as
construction methodology. This temporary sheet pile will be removed at
projection completion or upon written notice by DCM. T'h1s 1s
