Construction and Rehabilitation History
Two parallel, 660-ft-long steel sheet-pile jetties, spaced 300 ft
1937
apart, were constructed at this man-made inlet. Each jetty was com-
in diameter and inter-
posed of 19 cylinders (caissons), 15 to 20
connected by linear sections of sheet pile (Figure 3 )
Each
cylinder was backfilled with sand, and a stone and grout cap was
placed in the upper foot. The crest elevation of the jetties was
ft mlw. A channel 100 ft wide and 8 ft deep was dredged through
the inlet. The jetties were connected to the shore via creosoted
wooden sheet-pile bulkheads. The total cost for the jetties and
bulkheads was 7,000.
Limestone enrockments were placed along all exposed sections of the
1938-
1940
jetties (Figure 3 )
layer (4,000 tons), followed by

a layer of 50- to 200-lb (8,000-ton) stone, and covered with 500- to
6,000-lb (10,800-ton) stone placed on
side slopes at an ele-
ft mlw. The total cost of the improvements was
vation of
2,000.
Jetty surveys showed that the heads and seaward sides of the jetties
1950-
needed repairs. The channel side of the north jetty needed repair
1951
because of the proximity of the channel causing scouring at the toe.
Repairs were made to the seaward end of the south jetty which was in
1955
a "severely damaged" condition. A total of 650 tons of 3- to 6-ton
cover stone was placed on a 2-ft-thick foundation blanket of 2- to
6-in. stone at a total cost of ,500. Repairs were also made to
the collapsed concrete caps on the 1st and 8th caisson from its sea-
ward end. Nearly 3 / 4 of the first caisson was severely damaged, and
3- to 6-ton cover stone was placed to
ft mlw with a 10-ft crown
width. The upper 4 ft of the 8th caisson was filled with stone, and
the upper foot of this was capped with concrete grout.
Repairs to the concrete cylinder caps and jetty
revet-
1963
ments were made at a cost of ,000. At this time, the channel was
dredged to a depth of -9 ft mlw. Along the exposed seaward sec-
tions, 3- to 6-ton capstone totaling 615 and 770 tons was placed on
the north and south jetties, respectively, and approximately 20 cap-
stones were reset. Several of the seaward cylinders were repaired.
Their caps and sand were removed to -1 ft mlw, replaced with the
broken pieces of the cap and 20- to 200-lb stone, and grouted with
concrete throughout the upper 18 in. of stone.
