Construction and Rehabilitation History 



A survey in May showed crest heights of +2.5 to +8.5 ft mlw and 

 +2.0 to +9.0 ft mlw for the north and south jetties, respectively. 



A survey of the south jetty in December showed crest heights from 

 +1.5 to +9.0 ft mlw. 



At present, a 40-ft-deep by 400-ft-wide channel between the jetties 

 is maintained by the Navy (the Federal project depth is 32 ft). A 

 contract has been awarded to sand-tighten the landward 1,500 ft of 

 the south jetty. (As of 17 Aug 87 the job had not been completed.) 

 Plans call for removal of the existing jetty to -5 ft mlw, placing 

 an impermeable core of precast concrete sections (inverted Y-shape) , 

 and rebuilding to a crown elevation of +9 ft mlw using 8-ton 

 (maximum) armor stone.
