In addition to the work already in progress, plans for beach improve- 

 ment include the following: 



1. Riprap protection along the Maine Avenue bulkhead. Because 

 of the swift currents in the deep channel along this west shore of 

 the inlet, local authorities believe that maintenance of beaches here 

 will be difficult and that riprap protection will be necessary to 

 prevent undermining of the bulkhead . 



2o Construction of one or more groins along the beach between 

 the Oriental Avenue jetty and the west limit of beach restoration in 

 the vicinity of Illinois Avenue. The purpose of these structures is 

 to prevent or reduce the loss of the new fill from the beacho 



An attempt is being made by the Corps of Engineers to open a channel 

 eastward of the present channel by "harrowing" the bar. A steel frame 

 fitted with projecting spikes, or teeth, is pulled along the bottom by 

 two tugs in much the same manner as a farmer harrows a plowed field. By 

 continually traversing the same course it is hoped that the hard-packed 

 bar sand can be loosened sufficiently to be transported by inlet currents, 

 thus providing an incipient channel. This channel may be enlarged and 

 deepened by the natural flow ultimately resulting in the new channel 

 becoming the principal navigable channel for the inlet.
