 Ventura Marina Structures 

 Ventura Marina, California 



Date(s) Construction and Rehabilitation History 



1963 Construction of the marina was completed by local interests. 



Structures included a 1 ,254-ft-long north jetty, a 1 ,071-ft-long 

 south jetty, and a 250-ft-long middle jetty (Figure 24). The north 

 and south jetties were constructed with a crest el of +20 ft mllw 

 and a crest width of 15 ft with 1V:1.5H side slopes. The ocean 

 side of these jetties was armored with a single, uniform layer of 

 10.68-ton tribars. The middle jetty had a crest width of 24 ft 

 with varying els and 1V:1.5H side slopes. 



1968 A 1 ,500-ft-long detached rubble-mound breakwater and dredging of a 

 sand trap were authorized. Also, the authorization plan provided 

 for the US to maintain the existing jetties and channels previously 

 constructed by local interests. 



1971 Minor repairs were completed at the head of the north jetty. The 

 repairs consisted of resetting displaced and broken tribars on the 

 seaward end of the jetty and reshaping the jetty head with 3-ton 

 stone. 



1972 Construction of the 1 ,500-ft-long offshore rubble-mound breakwater 

 authorized in 1968 was completed (Figure 24). The structure had a 

 16-ft-wide crest with an el of +20 ft mllw. Side slopes were 

 1V:1.25H on the harbor side and 1V:2.25H on the ocean side. 



1986 The structures currently are in good condition.
