Subject: Hatteras Inlet Channel Maintenance Project — Written Notice of Project Initiation
Dear Mr. Trowell:
The Division of Coastal Management (DCM) issued a CAMA Major Permit for the proposed Hatteras Inlet Channel
Maintenance Project on December 22, 2016 (#129-16). This letter serves as written notice of project initiation as
required in Condition 7 of the permit. Please find attached to this letter revised permit drawings dated February 2,
2018, which provide the location of the proposed channel for the upcoming event.
At present, the project is anticipated to commence on or about February 9, 2018 and last approximately 5 days. The
project includes maintenance dredging within a portion of the Hatteras Inlet Connector Channel, which runs between
the inlet gorge and the ferry channel in proximity to Ocracoke Island. This channel is locally referred to as the "South
Ferry Channel". The attached plan view drawing shows the location of the proposed channel, the disposal area, and
previously mapped SAV in the vicinity. The channel will be dredged by the US Army Corps of Engineers (USACE)
special purpose dredge Currituck. Material dredged from the channel will be transported out Hatteras Inlet and
disposed of within the nearshore disposal areas located offshore of the north end of Ocracoke Island.
We have contacted Don Field with NOAA to determine if any updated imagery is available for this area that has been
used to delineate SAV habitat. Mr. Field responded that they do not have any update aerial imagery, but that there is a
possibility of funding for new imagery to be acquired later this year. In the CAMA Major Permit, DCM indicated that
DMF staff may perform SAV surveys in proximity to the proposed dredge location to provide an updated
determination of the presence or absence of SAV resources.
The permit allows for maintenance of a 100 ft. wide channel to a depth of -12 ft. MLW. Based on the January 25,
2018 survey, there are approximately 5,000 cy of material that could be removed above the -7 ft. MLW contour and
12,000 cy of material above the -8 ft. MLW contour. Based on the number of days available to conduct maintenance
dredging, it is not expected that the channel will be dredged to the full permitted depth of -12 ft. MLW.
As you may be aware, Dare County is seeking a permit modification to widen the permitted channel from 100 feet to
200 ft. in this vicinity. The proposed February event will not attempt to dredge the wider channel. At present, Dare
County and the USACE are planning an additional maintenance event in early spring that will attempt to dredge the

wider channel. That event has been designed to minimize the potential for additional dredging events in late spring or
during the summer months and is expected to last approximately 15 days.
With regards to contact information during dredge activities, Jim Medlock of the USACE will be the point of contact
for the USACE dredging operations. Jim's Phone Number is [phone] and his email is
Tames.M.Medlockkusace.army.mil. I will be the County's agent and can be contacted via cell phone at (910) 443-
4471.
Please feel free to contact me anytime for further clarification or explanation of the project.
Very truly yours,
