 Craig, Alaska 



Date(s) Construction and Rehabilitation History 



1945 The project was adopted, including a dredged mooring basin in South 

 Cove. 



1975 The floating dock system was expanded by local interests. 



1977 A storm damaged vessels in the expanded portion of the floating dock 

 system. 



I98I- Two breakwaters were constructed to protect the expanded area of the 

 1983 dock system. The north breakwater was I6O ft long, and the south 



breakwater was 300 ft long. Both breakwaters were constructed to a 

 crest elevation of +20 ft mllw, a crest width of 8 ft, and 1:1.5 side 

 slopes. The breakwaters were constructed with a core of quarry-run 

 rock covered by a filter layer of 150- to 1,500-lb rock, and an armor 

 layer of 2,200-lb rock with a range of 1,500 to 3,000 lb. The break- 

 water was designed for a significant wave height of 5.3 ft; the armor 

 rock was designed for the 10 percent wave height of 6.7 ft. 



1985 The harbor is illustrated in Figure 7, and an aerial photograph of 



the harbor is presented in Figure 8. There are no reports of needed 

 repairs or rehabilitation.
