Date(s) Construction and Rehabilitation History 



1978 An inspection revealed that the north jetty slope was eroded at 



several locations, and 12 blowout holes were apparent in the con- 

 crete cap. Also, at the north jetty head, waves had broken away a 

 20-ton concrete block from the concrete monolith which washed 

 across the monolith and was resting against a tip of a dolos. The 

 slope of the south jetty had eroded in numerous locations, and the 

 parapet wall had broken at four stations. Nineteen blowout holes 

 were observed in the south jetty concrete cap. Also a 7-ft stone 

 had broken out of the parapet wall and was deposited on the 

 concrete cap. 



1983 Major storms resulted in an estimated $2,000,000 in damages to the 

 jetties. 



1984 Repair of the south jetty consisting of 4,900 tons of 15- to 25-ton 

 stones and replacement of 20-ton concrete blocks at the jetty head 

 was completed. Also 16,665 tons of 15- to 25-ton stones and 

 16,665 tons of 18- to 31-ton stones were stockpiled on the harbor 

 side of the jetty. 



1985 Repair of the jetty heads was completed using a total of approxi- 

 mately 1,000 42-ton dolosse in various areas and the construction 

 of toe berms.
