Date(s) Construction and Rehabilitation History 



1958 Riprap was placed on both sides of the east breakwater on the outer 

 100 ft of Section C (Figures 59 and 60). The outer 820 ft of the 

 east breakwater (Figures 59-61 » Sections E-G) was reconstructed dur- 

 ing this period as rubble-mound breakwaters. 



1961 Riprap was placed around the outer end of the west breakwater and for 

 a distance of 200 ft on each side (Figure 59, Section D) . Riprap 

 also was placed around the outer end of the east breakwater and 

 150 ft along each side (Figure 59, Sections F and G) . 



1963 Rehabilitation of navigation structures included reconstruction of 

 the inner 470 ft and 624 ft of the west and east breakwaters, re- 

 spectively (Figure 59, Sections A and B) . Also included in the 

 rehabilitation was reconstruction of the pier (Figure 59, Section H) . 

 The shoreward 88 ft of the pier included a rubble-mound structure 

 (Figure 61, Section H) , 8 ft wide, with a crest el of +4 ft Iwd and 

 side slopes of 1V:1.5H. 



1981 An inspection of the breakwaters revealed that the east breakwater 



had some areas where the concrete cap was in an advanced state of de- 

 terioration, and the stone fill had washed away. The west breakwater 

 required some stone fill also and new concrete in some areas. Break- 

 water repairs were made subsequent to the inspection. 



1986 The structures have been reconstructed and repaired during their his- 

 tory and presently are in fair condition.
