Date(s) Construction and Rehabilitation History 



1980 A site inspection of the structures indicated that they were in good 

 condition but required minor repair in the form of a finishing touch 

 on the grouted cap to improve their appearance. The work was subse- 

 quently completely. 



1982 Construction of breakwaters and other improvements within the exist- 

 ing harbor was completed (Figure 83). A 725-ft-long west breakwater, 

 a 320-ft-long east breakwater, an absorber, and a parapet wall were 

 installed. The east and west breakwaters were rubble-mound struc- 

 tures with a 12-ft-wide crest width covered with 4.2-ton armor 

 (Figure 84). Side slopes were 1V:1.5H. The crest el of the west 

 breakwater was +8 ft Iwd, and steel sheet pile was included to make 

 the structure impervious. The east breakwater had a crest el of 

 +12 ft Iwd. An absorber and a parapet wall were installed along the 

 existing north breakwater adjacent to the harbor (Figure 84). The 

 absorber, installed at an el of +4 ft Iwd, was comprised of 2-ton 

 cover stone. The crest el of the parapet was +7 ft Iwd. The 

 improvements were model tested (Bottin 1977) prior to construction. 



1986 The structures presently are in good condition.
