19. ABSTRACT (Continue on reverse if necessary and identify by block number) 



This report is seventh in a series of case histories of US Army Corps of Engineers 

 (Corps) breakwater and jetty structures at nine Corps divisions. Chronological histories 

 are presented for 52 projects located along the New England coastline and managed by US 

 Army Engineer Division, New England (NED). Presently, NED is responsible for 37 jetties 

 and 46 breakwaters which have a cumulative length of 154,185 ft and are almost entirely of 

 stone construction. Localized damage from wave attack appears to be the major cause of 

 structural deterioration. A total of 36 projects has had structural modifications and/or 

 repairs since original construction. Almost all the repairs have consisted of placing new 

 stone on the structures.
