Subject: Hatteras Inlet Channel Maintenance Project —Written Notice of Project Initiation
Dear Ms. Coats:
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 permit was subsequently renewed
on January 22, 2020 and has a current expiration date of December 31, 2024. 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 January 28, 2022, which provide the location of the proposed channel for
the upcoming event.
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 submerged aquatic vegetation (SAV)
resources in the vicinity. The channel is proposed to be dredged by the US Army Corps of Engineers
(USACE) side cast Dredge Merritt. Material dredged from the channel will be sidecasted to either side of
the proposed channel.
The environmental window for dredging opened October 1. The USACE and Dare County have agreed on
a tentative schedule to begin dredging in early March 2022. The actual dredging of the channel is
anticipated to last approximately three (3) weeks. Depending on the actual start date of dredging, it is
possible that dredging could be required in early April, outside of the environmental windows established
by the permit. While it is too early to know whether dredging in April will be necessary to complete the
maintenance, this information is being provide to DCM for situational awareness.
As you are aware, the Major CAMA Permit (#129-16), allows for maintenance of a 200 ft. wide channel to
a depth of-12 ft. MLW. Based on budget, dredge availability, and conditional surveys conducted January
24, 2022, the proposed channel dimensions for this upcoming dredging event are to establish a 200-foot
wide channel at elevation -8 ft MLW. Based on the conditional survey from January 24, 2022, the
establishment of the proposed channel will require the dredging of approximately 40,000 cy of material.
Please note that these channel dimensions and configurations are what is anticipated, but we reserve our

authorization to increase the depth up to -12 ft. MLW. The proposed channel is shown on the attached
drawings, including both plan view and cross -sectional view.
As required by the permit, we have contacted Don Field with the Albemarle Pamlico National Estuary
Partnership (APNEP), to determine if any updated imagery is available for the project area to delineate
SAV habitat. As of the date of this letter, we have not received a response from Mr. Field; however, once
we receive a response, we will provide that to your agency via email. Our last information from February
2021 was that the Albemarle Pamlico National Estuary Partnership (APNEP) collected new imagery in
May/June 2020 and NOAA was awaiting deliverables to be provided by the contractor. We made the
formal request that the imagery and delineation be provided to us when available.
Regarding 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
[e-mail]. I will be the County's agent and can be contacted via cell phone at
[phone].
Please feel free to contact me anytime for further clarification or explanation of the project.
Sincerely,
/ ,
