Construction and Rehabilitation History

There were areas of partial washouts of stone, settlement, and

1985

(Cont.) interlocking capstones. The seaward 300 ft was completely unraveled,

with all stones scattered (Figure 1 ) It was determined that the

jetties had served their function of inlet stabilization and they

were not leaking significant amounts of sand.

1986

Plans call for rehabilitation of the jetties. The east jetty will

need new capstones and core stones where there are complete washouts,

approximately 450 ft. Original stones will be removed and reset

where settlement and sloughing has occurred, approximately 700 ft.

The 300-ft east jetty head section will be completely rebuilt with

new and original stone. A blanket will be

for scour protec-

tion. A 5.0-ft-thick blanket using 1,000-lb stone will be laid on

the existing bottom to prevent additional scouring of the west jetty

toe. New capstone and core stone are needed to supplement the dis-

placed stones of the west jetty head. The section,will be rebuilt

using existing stone but will consist of two layers of armor stone.
