shore of Kachemak Bay on Cook Inlet, 1 0 air miles south of Anchorage and

boat basin dredged to -12

a 600-ft detached south breakwater.

protected by two rubble-mound breakwaters.

cluded a 4.7-acre basin dredged to -12.5 ft mllw, protected by a 580-ft south
breakwater. A 950-ft north breakwater was added in 1937 and raised in 1953.

The original harbor was completely destroyed in the 1964 earth-
quake. The harbor was relocated and rebuilt during 1964 to 1965, including a
4.75-acre replacement basin dredged to -12.5
mllw, a 12.45-acre extension
dredged to -15
mllw, a 1,060-ft rubble-mound south breakwater, and a
1,750-ft rubble-mound east breakwater.
54. A Detailed Project Report and Final Environmental Impact Statement
were prepared in 1982 for expansion of the harbor. The study recommended that
a 30-acre basin be dredged 2 miles northeast of Seward, protected by a
1,400-ft south breakwater, a 2,500-ft west breakwater, and a 1,700-ft north
silt-barrier breakwater. There was no record of action taken since the study
was prepared. A chronology of events related to the development and repair of
the harbor structures is
