Date(s) Construction and Rehabilitation History 



1963 The timber training wall was rebuilt, and rock was placed at the foot 

 of the training wall. 



1968 Logs were cabled and buried in the spit. 



1972 Gabions were placed along the south basin wall to prevent gravel 

 washing over from the spit. 



1973 Dredged material was much finer than previously. A rock blanket 

 covering the spit was recommended with a life expectancy of 10 years. 



1974 The rock blanket was installed using 50,000 tons of rock. 



1978- The rock blanket on the spit was replaced. The estimate of a 10-year 

 1979 life for the blanket was not met. The spit was breached during a 

 storm in December 1979. 



1979 The south jetty was repaired. 



1980 Emergency repairs were made on the spit. 



1985 The harbor and cross sections of the jetty are illustrated in Fig- 

 ure 77. The outer 250 ft of Jetty was lowered to a point that the 

 jetty was awash at high tides. Repair or rehabilitation is not 

 anticipated in the near future.
