1982 providing for insufficient impounding capacity. Shoaling in the 

 (Cont) vicinity of the weir apparently resulted from inadequate maintenance 

 of the deposition basin, which had only been dredged once 

 (287,000 cu yd removed in 1972). The report recommended closing the 

 weir section of the west jetty since the net littoral drift was, in 

 fact, from east to west to reduce the shoaling in the inner channel 

 areas caused by westward littoral drift passing through the weir 

 section. 



1985 The weir section of the west jetty was modified with the placement 

 of a rubble-mound trunk section Identical to the trunk section used 

 in the original design (except that the blanket stone was to have a 

 minimum thickness of 1 ft directly over the sheet piles and 2.5 ft 

 thick elsewhere as called for in the original design) . Estimated 

 volumes of blanket, core, and cover stone were 5,300, 1,500, and 

 4,600 cu yd, respectively. At present, toe stability problems exist 

 and have been documented with video footage of scour along the toe 

 of the east jetty. Otherwise, the jetties are in good condition.
