Haines Small-Boat Basin 



Haines, Alaska 



Date(s) Construction and Rehabilitation History 



1958 The original breakwater was constructed. 



1971 The project was adopted. 



1976 The project was completed, including a 4.2-acre boat basin dredged by 

 local interests to -12 ft and -15 ft mllw, and an entrance channel 

 maintained by the Corps to -15 ft mllw. The seaward leg of the 

 existing breakwater was removed, and a 905-ft crescent-shaped off- 

 shore breakwater was constructed. The crest elevation on the new 

 breakwater was +26 ft mllw, the crest width was 4 ft, and side slopes 

 were 1:2 on the seaward side and 1:1.5 on the harbor side. The 

 breakwater was constructed with a rubble core covered by armor rock. 

 The crest width and outer face of the trunk were covered with 2.5 ft 

 of 300-lb rock. Armor on the ends and first and last 100 ft of the 

 trunk consisted of 3 ft of 400-lb rock. The remainder of the inner 

 face was covered with three ft of 40-lb rock. A gap was left between 

 the offshore breakwater and the older breakwater to protect salmon 

 fry and promote circulation in the basin. 



1985 The harbor is illustrated in Figure 11, and an aerial photograph of 



the harbor is presented in Figure 12. There are no reports of needed 

 repairs or rehabilitation.
