Construction and Rehabilitation History
1891-
Three rubble-mound breakwaters were constructed and maintained,
1914
ft-long V-shaped main, 2,240-ft-long east shore arm, and 3,640-ft-
long west shore arm breakwaters were built during 1891-99,
and 1911-14, respectively. The main breakwater was constructed in
water depths from 1 to
8
(relative to rnlw), and the east and
west shore arms were built in depths of up to 26 and 1 ft, respec-
8
tively. The design cross section for the main and east shore arm
ft r l crown elevation, a
nw
harbor side slope, and a composite sea-
20-ft crown width, a
side slope of
and
above and below -12 ft mlw, respec-
tively. Subsequent to construction of the main breakwater (date
unknown), the design sea-side slope on its west arm was changed to
Two design cross sections were used on the west shore arm
width and a
ft r l crown elevation, and the remaining seaward
nw
section had a 15-ft crown width and a
rnlw crown elevation.
Slopes on both sections were
and
on the harbor and sea
sides, respectively. Core stone (size unknown) was placed to rnlw on
cover stone, size unknown) was
all sections and facing stone
placed to a thickness of 1 ft on all sections, except on the west
0
shore arm's landward section where the thickness was 8 ft. A total
of 1,421,500tons of stone was placed at total construction costs of
,149,500. Starting in 1905, repairs were made on previously
completed portions of the breakwaters by adding and resetting
stone. Most of the repairs were located on the east arm of the main
breakwater and the east shore arm breakwater. These areas were
exposed to the largest waves generated by several winter storms which
occurred during this period. Maintenance costs totaled approximately
0,000using an additional 36,400 tons of stone.
1927-
Repairs were made to the main and east shore arm breakwaters which
1929
had numerous deficiencies in cross section due to wave attack. The
west shore arm breakwater was in good condition. Approximately
40,000 tons of stone were used for a total cost of 3,400.
The main breakwater was repaired using 6,760 tons of stone for a
total cost of ,000.
Damaged sections of the main and east shore arm breakwaters,
1939-
sustained during a 1938 hurricane, were repaired using new and reset
1941
stone. A total of 46,700 tons of new stone and 4,980 tons of
salvaged stone were placed for a total cost of 3,400.
