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 October 17,
2018, which provide the location of the proposed channel for the upcoming event
At present, the project is antiapatd to be conducted between November 1, 2018 and November 30, 2018. The
actual dredging of the channel is anticipated to last approximately 20 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 mew 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 Cm csrk. Material dredged from the channel will be transported out Hatteras Inlet and disposed of widen the
nearshon, disposal areas located offshore of the north end of Ocracoke I sland.
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 in the spring of 2019. 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 original permit allowed for maintenance of a 100 ft wide channel to a depth of -12 ft. MLW. After a request
from the proj ect sponsor in February 2018, the DCM issued a Modification to Permit 129-16 on March 14, 2018,
when authorized the expansion of the channel width from 100 feet to 200 feet Based on the October 2, 2018 survey,
removal of approximately 19,000 cy of material would be sequined to achieve a channel depth of -8 ft. MLW within
the proposed channel shown on the attached drawings. 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.

With regards to contact information during dredge activities, Brennan Dooley of the USACE will be the point of
contact for the USACE dredging operations. Brennan's Phone Number is [phone] and his email is
Brennan.I.DoolQ:kusace.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,
