Construction and Rehabilitation History
1944
North jetty repairs using 10,840 cu yd of concrete and south jetty
repairs using 1,502 cu yd of concrete were completed at a cost of
,740.
South jetty repairs using 3,342 cu yd of concrete were completed
1945
for ,560.
1950
The south jetty was breached over a 70-ft span on the sea side.
Side slopes were reconstructed with mass concrete to conform to
existing adjacent slopes to el of +18 ft mllw.
1951
South jetty repairs using 1 0 1 cu yd of concrete were completed at
,8
a cost of ,805. Also, twelve 100-ton concrete blocks were
installed.
South jetty repairs using 470 cu yd of concrete were completed at a
1952
cost of ,107.
Major damage was sustained on the channel side of the north jetty.
1957
The total length of damage on the jetty was 410 lin ft at five
locations. Also, the concrete monolith at the outer end of the
structure was completely devoid of stone or concrete protective
side slopes at this time. Major damage to the south jetty had
similarly occurred. Breaches through the center section had oc-
curred at two locations with major loss of side slopes at three
locations. The concrete monolith at the outer end was exposed in a
manner similar to that of the north jetty. The condition of the
jetties at this point was not due to a specific storm but repre-
sented deterioration over a period of years. Tetrapods weighing
25 tons were placed on the north jetty and 15 tons on the south

Severe winter storms deteriorated the north and south jetties to
such an extent that repair work constituted a major construction
1958
project.
Mass concrete was poured to fill eroded areas on crests, and armor
1958
stones were replaced in areas that were breached and washed out.
Concrete blocks ( 1 1 by 1 1
weighing 1 0 tons and 12-ton tetra-

hedrons were placed on the heads of both jetties.
Major side slope losses on the south sides of both the north and
1959
south jetties occurred.
Rehabilitation of both jetties was accomplished. Jetty trunks were
repaired with 12-ton stones placed on
slopes in the eroded
1963
areas. Jetty heads were reconstructed using 20-ton blocks to form
head perimeters, and centers were filled with mass concrete.
Two-hundred and fifty 100-ton concrete blocks were placed around
the seaward tip of the south jetty head. The concrete monolith at
