Marine Corps Air Station (MCAS) Cherry Point is proposing the repair of
a failing bulkhead at Thorofare Bridge, near Piney Island (Bombing
Target -11), Carteret County. The project will permanently impact 0.02
acres of open water within Thorofare Canal.
The bulkhead on the north side of the property was replaced in 2011
(DWQ Project #09 0291 Mod). The primary purpose of this project is to
replace the bulkhead along the western edge of the parking area
beginning at the end of the previous renovation and extending south
approximately 135 ft.
The timber bulkhead and timber dock on the western side of
government property at Thorofare Bridge is deteriorated and has
effectively failed at several locations causing loss of retained earth
fill on the land side behind the bulkhead at several locations. The
height of the existing bulkhead is estimated to range from about 5.5 to
9 feet above the mud line.
MCAS Cherry Point plans to drive new steel sheet piles immediately
outboard of the existing bulkhead with a new concrete cap, leaving the
existing timber sheet piling in place. The replacement bulkhead will be
comprised of a tie -back steel sheet pile system with a concrete cap and
timber pilings. Demolition of the existing timber dock will be required
to install the new bulkhead. Construction of a replacement timber dock
is not required.
A temporary turbidity curtain will be installed to prevent sediment
and concrete from entering state waters. Off -site structural backfill
will be placed and compacted landside of the bulkhead to final grades.
Erosion and sediment control measures will include: Silt fence;
construction entrance; and sodding to prevent sediment laden runoff from
draining off -site.

This notification= °is for the record only._ :'Notification of the _
action will -be sent to' the 'U. S,. ,Army' Cdrps - of Engineers 'arid a request'
for concurrence with a Coastal' Consistency Determination - will be sent to
the.NCDEQ Division of Coastal Management.
