Construction and Rehabilitation History
1968
Repair work was completed in August. A total of 1 1 areas was
paired. Due to the severity of wave overtopping and the
of damage in many areas, the armor stone weight used for
of 8 tons to a
repair of the crown was increased from a
minimum of 10 tons. The remainder of the repair work followed the
original cross section design. The total cost of repair was
approximately 4,500.

structure was needed to protect the berthing area. Emergency
repair work was completed in 1973 at a cost of 4,000. The
original cross section design was used for repair.
Major repair of the breakwater was completed. Both new and reset

8- and 10-ton minimum weight armor stones were used to repair
various areas along the entire length of the structure. The
structure slopes and crown elevation were unchanged from the
original design cross section. The total cost of the work was
approximately 1,000.
Hurricane Kate produced overtopping waves at various lengths of

onto the crown or was missing. No immediate repairs were
recommended.
