Construction of two rubble-mound breakwaters at the site (Fig- 

 ure 32) was completed. The west breakwater was 5,500 ft long with 

 a 16-ft-wide crest at el of +18 ft mllw. The ocean side slope of 

 the structure was 1V:2H, and the harbor side was 1V:1.25H. The 

 east breakwater was 2,250 ft long with a 14-ft-wide crest width 

 and a +l4-ft el mllw. The ocean-side slope was 1V:1.5H, and the 

 harbor-side slope was 1V:1.25H. Model tests were conducted for the 

 project (Dai and Jackson 1966, Wilson 1966). 



Major storms resulted in approximately $610,000 in damages to the 

 breakwater . 



Restoration of the west breakwater in nine locations was completed. 

 About 5,800 tons of capstone were used for this maintenance repair. 



The breakwaters are in satisfactory condition.
