Date(s) Construction and Rehabilitation History 



1963 The south jetty was rehabilitated. The crest elevation varied, but 

 it was +26 ft mllw at the head. The crest width was 26 ft, and side 

 slopes were 1:2 above mllw on the ocean side but 1:1.5 elsewhere. 



1964 The hydraulic model study at WES recommended extension of the train- 

 ing Jetty. 



1977 The north Jetty was rehabilitated. The crest elevation was raised to 

 +20 ft mllw with a crest width of 28 ft and side slopes of 1:1.5 on 

 the channel side. Side slopes on the ocean side were 1:2 above mllw 

 and 1:1.5 below mllw. The head of the Jetty was at elevation +21 ft 

 mllw with a crest width of 28 ft and side slopes of 1 :2 above mllw 

 and 1:1.5 below mllw. 



1978- The training jetty extended to the end of the south jetty. The 

 1980 extension had a crest elevation of +14 ft mllw, a crest width of 

 30 ft, and side slopes of 1:1.5. The core stone was covered with 

 armor stone to elevation -10 ft mllw. The armor layer was 12 ft 

 thick on the channel side and on the crest and 6 ft thick on the side 

 of the embayment between the training Jetty and the south jetty. 



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

 ure 64. The jetties appear in good condition at this time.
