Subject:Hatteras Inlet Maintenance Dredging Pre-Construction Meeting
Attachments:DCM Written Notice_2017 09 05.pdf
All,

I wanted to reach out to you to see if we could set up a brief call to serve as the permit mandated pre-construction
meeting for the next Hatteras Inlet Connector Channel maintenance event. As detailed in the attached written notice,
the USACE, County, and CPE-NC have been in discussions since we obtaining updated survey data early last week
regarding the preferred channel location. At present our marine archeologist contractor is conducting surveys in the
permitted corridor that are designed to clear the potential channel alignments being considered. It is my understanding
that at present, the USACE is planning to begin dredging between Sept. 12 and 14.

Please let me know your availability for a call to discuss this project on Thursday or Friday of this week. I realize that this
is short notice, but we only received updated survey data last week and we are working to try to clear as much of the
channel as possible with the cultural resource survey to provide flexibility in where we can dredge.

Kind Regards,

Ken Willson

Subject: Hatteras Inlet Channel Maintenance Project — Written Notice of Project Initiation
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.
At present, the project is anticipated to commence on or about September 12, 2017. 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. The channel will be dredged by the US
Army Corps of Engineers (USACE) sidecast dredge Merritt. The Merritt is the only sidecast dredge currently
operated by the USACE Wilmington District. At present time, the County, USACE, CPE -NC and local
users are in discussion regarding the best location to conduct the next maintenance event. The attached
maps show the latest survey conducted by the USACE (hatteras inlet connector channel— expanded survey area —
august 2017 — RC 05—HST 20970821 pdA and several locations in which dredging is currently being
considered (Hatteras Inlet Connector Channel — Expanded Survey Area — August 2017 survey—.pdf .
Our marine archeologist is currently conducting surveys to clear the areas shown in the map referenced
above. As required by the CAMA permit, the survey method has been approved by the NC Dept. of
Natural and Cultural Resources State Historic Preservation Office as evidenced by the attached letter. Upon
completion of this survey and establishment of appropriate buffers, the area proposed to be dredged will
have met the requirements of Condition 8 of the permit. We are in discussions with NC DMF regarding
any updated information on SAV beds in proximity to the project area based on the interpretation of aerial
imagery. 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.
As soon as final dredging plans have been developed we will provide engineering drawings and the
estimated volume to be removed from the channel based on the August 2017 USACE survey. The permit
allows for maintenance of the 100 ft. wide channel to a depth of -12 ft. MLW. No dimensional changes to
the permitted channel are being proposed. However, the limited time available for construction (10 days)
may not allow for the channel to be dredged to the maximum -12 ft. MLW depth. Once the proposed
channel has been finalized and the volume of material is computed, we will provide your office with an
updated volume and schedule for project completion.
