Zuniga Jetty 



San Diego Harbor, California 



Date(s) Construction and Rehabilitation History 



1894- Construction of a 7,500-ft-long rubble-mound jetty (Zuniga Jetty) 

 1902 was completed (Figure 35) during this time frame. The design 



height of the jetty was +14 ft mllw with a 14-ft-wide crest. Side 

 slopes were 1V:1.25H. It is indicated, however, that the jetty was 

 not constructed to the full design height. 



1942 Rehabilitation work was performed by the US Navy from the shoreward 

 end to a point about 1,400 ft seaward. 



1943- Settlement and flattening of the slopes occurred, particularly in 



1969 the outermost third of the jetty. As a result, parts of the jetty 

 were awash or submerged at most tide stages, creating hazards to 

 navigation. 



1970 Maintenance repair of the jetty was accomplished for a cost of 

 approximately $127,000. This work consisted of the construction of 

 platforms on the jetty for navigation lights which were installed 

 by the US Coast Guard to alleviate hazards to navigation. 



1984 Maintenance repair of the jetty was completed, the extent of which 

 is unknown. 



1986 Even though the jetty was not constructed to full design height, it 

 functions satisfactorily as a training wall which concentrates 

 tidal flows and keeps the entrance channel scoured to project 

 depth.
