 Kodiak Harbor 

 Kodiak, Alaska 



Date(s) Construction and Rehabilitation History 



1935 A channel was authorized between Kodiak Island and Near Island to be 

 200 ft wide and later dredged to -22 ft mllw. 



1954 The project was modified to include a small-boat basin. 



1957 Construction of the breakwaters was initiated. 



1958 A rock ledge was removed from the basin and channel. Construction 

 of the breakwaters was completed. The southeast breakwater was con- 

 structed of a mound of Class "C" stone to an elevation of +18.5 ft 

 mllw, a crest width of 6 ft, side slopes of 1:1.5, and length of 



789 ft. The 1 ,250-ft-long southwest breakwater was constructed to an 

 elevation of +22 ft mllw, a crest width of 6 ft, and side slopes of 

 1:1.5. The breakwater was constructed of a mound of Class "C" stone 

 covered with a 6-ft layer of armor stone on the crest and a 4-ft 

 layer of armor stone on the seaward side. 



1964 The ground subsided 5 ft in an earthquake causing severe damage to 

 the basin and breakwaters. The breakwaters were rebuilt with 

 70,000 tons of rock. Cross sections of the repaired breakwaters are 

 shown in Figure 27. 



1973 The tip of the southeast breakwater was repaired. 



1985 The harbor is illustrated in Figure 27, and an aerial photograph of 

 the harbor is presented in Figure 28. There have been no reports of 

 needed repairs or rehabilitation since 1973.
