This letter serves as the project report required by special condition #24 of the above referenced permit, which allowed
Dare County to conduct maintenance dredging within the Connector Channel Corridor located between Ocracoke
Island and Hatteras Island, North Carolina. Special condition #24 requires that a project report summarizing the results
of the dredging and the sea turtle take (if any) be submitted to NMFS within 30 working days of completion and that
the reports shall contain information on project location, start-up and completion dates, cubic yards of material dredged,
incidental takings (include photographs, if available) and sightings of protected species, mitigating actions taken,
screening type (inflow, overflow) utilized, daily water temperatures, name of dredge, names of endangered species
observers, percent observer coverage, and any other information the contractor deems relevant.
Project Description:
On December 16, 2018, the US Army Corps of Engineers (USACE) operated Special Purpose Dredge Cunituck began
dredging in the Connector Channel/South Ferry Channel in the vicinity of Hatteras Inlet. The Dredge Currztuck
conducted maintenance dredging in the channel for four (4) days through December 19. Following a short break for
the Christmas holiday, the Dredge Currituck resumed operations on December 29 and conducted maintenance dredging
of the channel through January 2, 2019. Due to scheduled maintenance requirements and other scheduling factors, the
USACE pulled the Dredge Cunituck from the project and replaced it with the Special Purpose Dredge Murden . The Dredge
Murden arrived on site January 4 and completed dredge operations on January 14.
During the first 4 days of dredge operations, the Dredge Cunituck utilized the temporary disposal site approved by state
and federal agencies. Material placed in the temporary disposal site was later removed and disposed of in the offshored
disposal area.
The Wilmington District USACE provided hydrographic survey charts showing the pre -construction (December 12,
2018) and post -construction Qanuary 15, 2019) depths in the channel. These maps are included as an attachment to
this letter (Attachment 1 — Connector Channel Maps). A comparison of the pre -construction survey conducted on
December 12, 2018 and post -construction surveys conducted on January 15, 2019, indicated that approximately 20,000
cubic yards of material was removed from the channel and associated side slopes. The removal of the material resulted
in controlling depths of approximately -8 ft. mean lower low water (MLLW) through the South Ferry Channel. The
resulting channel is approximately 150 feet wide.

Mitigation Actions and Observations:
No dredge operations associated with this event occurred between April 1 and September 30. The goal of the December
2018/January 2019 maintenance event was to establish a more direct channel orientation to the inlet gorge cutting across
a linear shoal and establishing an approximately 8 ft. deep channel with bottom width of approximately 150 ft.
APTIM staff coordinated closely with both NC DCM and USACE regulatory staff on the progress of the project. In
accordance with the permit, construction activities complied with the "Guidelines for Avoiding Impacts to the West
Indian Manatee". Furthermore, the project did not place any material above the MLW to avoid impacts to federally
listed Seabeach Amaranth, Piping Plover, Red Knot, Green sea turtle, Hawksbill sea turtle, Kemp's ridley sea turtle,
Leatherback sea turtle, Loggerhead sea turtle, and their habitat.
To the knowledge of the contractor, no protected federally listed species was killed, injured, captured, harassed, or
otherwise harmed by the conduct of the maintenance activities (i.e. no incidental takings). No protected species were
observed during the conduct of the work; however, protected species observers were not required as a condition of the
permit. During the initial three (3) days of dredge operations, the USACE utilizized the permitted Temporary Disposal
Area located on the south west side of the proposed channel to allow for more efficient dredge operations. Once
sufficient channel depths had been achieved to efficiently load the dredge and travel to the offshore disposal site, the
material dredged from the channel and the material dumped in the temporary disposal site was transported and disposed
of in the designated nearshored disposal site as shown on the attached drawings.
Please feel free to contact me should you have any additional questions regarding this project.
Very truly yours,
