Construction and Rehabilitation History
1953-
Two rubble-mound jetties, each 1,150 ft long, were constructed to

provide channel protection (Figure 3 )
built in 1953 to a length of 850 ft and extended 300 ft in
1954. A
foundation blanket of material ranging from sand
to 125-lb stone was placed as a base for each jetty. Core stone
ranged from 200 to 4,000
and was placed to an elevation of -1 ft
mlw. Capstone ranged from 2 to 8 tons at the shoreward ends to
tons at the seaward ends. Crest elevations ranged from 6 to 8 ft
above mlw, and the crest width was 12 ft. Side slopes were
over the inner 1,100 ft of the south jetty and the inner 800 ft of
over the next 300 ft of the north jetty.
the north jetty and
The remaining 50-ft sections had transition side slopes to
this being the side slope of the semicircular head sections. The
jetty design was based on Irribarren's equation using 9- and 12-ft
wave heights. The estimated cost of the jetties was 1,000.
1957-
Revetment was placed at the shoreward ends of the jetties. Splash

aprons were placed on the channel side of the jetties to prevent
scour from wave overtopping (no details).
1985
The jetties have not been repaired since construction and are in
good condition. The Federal project calls for a 37-ft-deep channel,
but the Navy presently maintains a 44- by 400-ft channel between the
jetties.
