Construction and Rehabilitation History 



700-ft section was repaired on the south jetty. A total of 

 45,000 tons of stone was placed, and additional stone was reset 

 (200 pieces) at a total cost of $232,000. 



A historical synopsis written at this time (which did not describe 

 the condition of the jetties) stated that "the structure has served 

 the purpose for which it was originally constructed." Repairs were 

 made to the north revetment in 1948. 



1983 At the shoreward end of the north jetty, a 1 ,200-ft-long section was 

 made sand tight in conjunction with beach renourishment north of the 

 jetty. The modification required raising the crest elevation, 

 rebuilding damaged sections, and chinking voids with small stone (no 

 details) . This modification would inhibit the loss of sand placed 

 adjacent to the jetty during, and subsequent to, beach nourishment. 

 The cost of the modifications was $608,000. 



1985 Presently a 38-ft-deep by 400-ft-wide channel is maintained between 

 the jetties. Except for the sand-tightened portion (1983), the 

 jetties have not been repaired since 1934 and, although in poor con- 

 dition, are still functioning properly.
