Construction and Rehabilitation History
Construction of a rubble-mound breakwater, approximately 2,400 ft
long, was completed at the site (Figure 22) during this time frame.
1913
The crest el of the structure varies from +14 ft to +18 ft mllw
on the ocean side
with a 14-ft width. The side slopes are
and
on the harbor side.
The structure was breached in a zone about 300 ft seaward of
1924
Whalers Island (Figure 22) by storm waves.
The breach formed in 1924 was filled with a concrete cap.
1927
The concrete cap placed in 1927 was washed away because of storm
1931
wave activity. A l s o , the head of the breakwater was damaged.
Repairs were made to damaged areas of the structure. The slopes in
1935
of -10 to
the damaged zones were covered with 14-ton stones to
-15 ft mllw.
Modification of the existing project was authorized. Included were
1976
a 750-ft-long south breakwater, a 3,615-ft-long detached break-
water, and dredging of associated channels and anchorage areas
Major storms resulted in approximately 8,000 in damages to the
1983
breakwater.
1984
Maintenance repair of the existing breakwater was completed which
consisted of approximately 8,700 tons of capstone placement and
resetting of 40 existing capstone. The crest width of the struc-
ture was increased to 20 ft. Plans and specifications for con-
struction of the modified project (authorized in 1976) were about
80 percent complete.
1986
The breakwater currently is in satisfactory condition.
