including a 5-acre basin protected by a 600-ft main breakwater and a 170-ft 



stub breakwater. The main breakwater was destroyed by a storm in 1981 and 



rebuilt and extended to 725 ft in 1983. The basin has a capacity of 



125 boats. A chronology of events related to the development and repair of 



the harbor structures is given in Table 15. 



Seldovia Harbor, Alaska 



49. Seldovia is located near the mouth of Seldovia Bay on the southern 

 shore of Kachemak Bay on Cook Inlet, 140 air miles south of Anchorage and 



15 nautical miles southwest of Homer. The project includes a 700-ft by 300-ft 

 boat basin dredged to -12 ft mllw, protected by a 400-ft north breakwater and 

 a 600-ft detached south breakwater. 



50. The project was authorized in 1958 and constructed during I96I to 

 1962. An earthquake in 1964 caused the basin to subside 3.8 ft. The break- 

 waters were therefore raised 4 ft in 1964. A chronology of events related to 

 the development and repair of the harbor structures is given in Table 16. 

 Seward Harbor, Alaska 



51. Seward is located on Resurrection Bay off the Gulf of Alaska, about 

 120 miles south of Anchorage. The project includes a 17-acre small-boat basin 

 protected by two rubble-mound breakwaters. 



52. The original project, authorized in 1930 and completed in 1932, in- 

 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- 

 During 1955 to 1956, the south breakwater was raised, and two pile breakwaters 

 were added on the eastern side of the basin. 



53. 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 ft mllw, a 12.45-acre extension 

 dredged to -15 ft 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 given in Table 17.
