The applicant’s stated purpose is to provide
additional berthing capacity within Dutch Harbor at the Light Cargo Dock (LCD).
The LCD currently acts an overflow area for the nearby Unalaska Marine Center
(UMC) Dock and also provides berthing space for other commercial and private
users. The applicant proposes to expand the existing
LCD, including: 1) the removal of two existing dolphins and catwalks (six
36-inch diameter steel king piles would be removed with a vibratory hammer,
with batter piles cut off at the surface and buried); 2) removal of the
existing armor rock between the existing bulkheads; 3) installation of an open
cell sheet pile bulkhead backfilled with 5,800 cubic yards (cy) of gravel fill
into 0.11 acre of navigable waters of
the U.S.; 4) installation of five 36-inch diameter steel fender piles and four
24-inch support piles with an impact hammer [with ten temporary 18-inch
diameter steel piles, installed with a vibratory hammer, for support during
construction activities]; and, 5) construct a 0.20 acre concrete dock surface
over new fill/sheet pile/fender piles. Work
would occur over, and below, the high tide line (HTL, approximate elevation
+6.7’ above the 0.0 foot contour) and mean high water mark (MHWM, approximate
elevation +3.3’ above the 0.0 foot contour) of Dutch Harbor. All work would be performed in accordance with the
enclosed plan (sheets 1-4),
dated January 4, 2016. Please contact Jen Martin at (907) 753-2730, by
fax at (907) 420-0813, or by email at jen.l.martin@usace.army.mil if further
information is desired concerning this notice.
