Construction and Rehabilitation History
1956
A 775-ft-long rubble-mound breakwater was constructed to provide
channel and harbor protection (Figure 7. The cross-section geom-
)
etry consisted of a
crown elevation, a 4-ft top width, and
and
on the river and harbor sides,
side slopes of
respectively. The structure was capped with l-ton stone. The armor
stone was sized using Hudson's slope stability formula and a 4-ft
design wave height. The core and l-ft-thick bedding layer consisted
of somewhat smaller stone. The estimated construction cost and
amount of stone needed were ,600 and 6,060 tons, respectively.
An inspection of the breakwater showed that an 80-ft section,
1973
cated approximately 1 0 ft from the outer end of the structure, was
0
2 ft below grade. This occurrence was attributed to structure set-
tlement. Overall, the breakwater was considered to be in very good
condition.
1985
The breakwater has required no maintenance or repair since its
completion.
