The project was authorized, including a 13-acre basin protected by a 

 1,430-ft main breakwater and a 200-ft entrance breakwater. The basin 

 was expanded to 15 acres during the design stage. 



The project was constructed, including a 15-acre basin dredged to 

 -10 ft mllw and two rubble-mound breakwaters. The breakwaters were 

 constructed to a crest elevation of +19.5 ft mllw, crest width of 

 8.5-ft, and side slopes of 1:1.5, and these consisted of a rock core 

 with a 4-ft layer of class "B" stone and a 6-ft layer of armor stone. 

 The design wave was 7 ft. Breakwater cross sections are shown in 

 Figure 46. 



Wave studies of the harbor were conducted due to damage to small 

 craft within the harbor. 



The entrance jetty was extended 135 ft. 



The harbor is illustrated in Figure 46, and an aerial photograph is 

 presented in Figure 47. There are no reports of needed repairs or 

 rehabilitation.
