1972- worst areas as low as +4 ft mlw. It was estimated that 1,000 and 



1974 500 tons of new and salvageable stone, respectively, were needed to 

 (cont.) repair the jetty. 



1975 The seaward 525-ft section of the west jetty was repaired to the 

 1968-69 design cross section using 4- to 7-ton cover stone and 500- 

 to 1,000-lb underlayer stone as needed (Figure 25, inset). The 

 repairs were made for a total cost of $40,000. 



1977 An inspection indicated that the east jetty was in good condition but 

 that the west jetty needed some armor stone reset. 



1986 Yearly inspections indicate that the jetties are in good condition. 

 For the purpose of this report, the lengths of the east and west 

 jetties are considered to be 645 and 850 ft long, respectively (the 

 1968-69 improvements plus approximately 150 ft of concrete wall 

 landward of the east jetty repair section).
