Santa Barbara Breakwaters 



Santa Barbara Harbor, California 



Date(s) Construction and Rehabilitation History 



1928 Construction of a 1 ,800-ft-long rubble-mound breakwater parallel to 

 and about 600 ft from the shore was completed. The crest el of the 

 structure was + 12 ft mllw with side slopes of 1V:1.5H. Ten-ton 

 stones were placed on the ocean side with 5-ton stones on the har- 

 bor side. The breakwater afforded protection from southwesterly 

 waves; however, shoaling occurred in the lee of the breakwater. 



1929 Navigational difficulties were experienced at the west end of the 

 Harbor as a result of the shoal. 



1930 The breakwater was extended to its present length of 2,365 ft and 

 connected to shore. An 18-ft-wide concrete walkway was installed 

 along the crest of the structure. After construction, sediment 

 migrated around the breakwater and deposited in the lee of the 

 eastern end forming a spit that encroached on the channel. 

 Maintenance dredging was initiated. 



1962 Modification of the existing project was authorized and included a 

 500-ft-long west breakwater extension, a 1 ,600-ft-long detached 

 breakwater, a 2, 500-ft-long east breakwater, and dredging of assoc- 

 iated channels, basins, etc. (Figure 23). Construction of the 

 modification has not been initiated, although it has been model 

 tested (Brasfeild and Ball 1967). 



1969 Modification of the existing project was reclassified to an in- 

 active category. 



1986 The structure presently is in satisfactory condition.
