to the beach between the groin and the stationary by-passing plant, 

 with the expectation that this reduction in supply will cause this 

 shore line to recede to the desired design alignment. The initial 

 behavior of the groin la as designed, even though it has not been 

 constructed to its final length. It was anticipated that the sand 

 eroded from between the groin and by-passing plant would be transport- 

 ed into the harbor and this condition is being resolved by having a 

 hopper dredge operate within the outer harbor. 



It is expected that when the groin has Deen constructed to its 

 design length, and its impounding capacity has been reached, the beach 

 to the east of the groin will have eroded sufficiently to enable the 

 stationary by-passing plant to operate directly offshore as originally 

 designed. 



To overcome the problem of pumping interruption occurring when 

 the pipe swing span is opened, an impermeable pier is planned on, the 

 harbor side of the west breakwater. This structure is designed to 

 serve two purposes, first, as a sand trap to prevent any further 

 shoaling of the outer harbor and, second, as a mooring place for hopper 

 barges which will receive the sand pumped by the stationary dredge. 

 The hopper barges will then be towed across the harbor where they 

 will be emptied by means of a pumping plant located on the eastern 

 breakwater, and the sand will be deposited on the beach east of the 

 breakwater.
