Bakers Haulover Inlet, Florida,
Construction and Rehabilitation History
1925
A man-made inlet was constructed by local interests.
Existing steel sheet-pile jetties (private construction, date

unknown) had rusted through, and wave action had partially removed
sand fill behind them. Loss of this fill caused the collapse of
portions of an 8-in. concrete cap on both jetties. The sheet-pile
jetties were removed and 150-ft-long rubble-mound jetties were con-
structed in their place (Figure 3 )
1,500- to 2,500-lb and 8- to 12-ton stone for the core and cap,
respectively. 12-ton minimum cap stone was placed on the outer
with a crown width
50 ft of the jetties. The side slopes were
and elevation of 1 ft and
0
ft mlw, respectively. The design was
based on a wave height of 14 ft and Hudson's slope stability
The centerline distance between the jetties was about 415 ft,
the south jetty being placed about 100 ft south of the sheet-pile
jetty. The channel was dredged to -11 ft mlw. Total cost of the
jetties and connecting revetments was 7,000.

The north jetty was essentially rebuilt to act as a sand-tight
minal groin since the existing jetty would not be effective in main-
taining the planned beach renourishment north of, and adjacent to,
the jetty. Prior to being rebuilt, an inspection indicated that the
jetty had held up well since its construction but that it was inef-
fective in retaining sand which passed through it and around its
seaward end. A general design
