Barcelona Harbor Breakwaters 



Barcelona, New York 



Date(s) Construction and Rehabilitation History 



1960 Construction of a 693-ft-long east and a 790-ft-long west breakwater 

 (Figure 257) was completed. The breakwaters were constructed with 

 cellular steel sheetpiling filled with granular fill and capped with 

 concrete. The cell diameters were about 38 ft, and the els were 

 +9 and +11 ft Iwd for the east and west structures, respectively 

 (Figure 257). A 174-ft-long steel sheet-pile shore arm connected the 

 west breakwater to shore. Its el was +9 ft Iwd. 



1984 Construction of a 250-ft-long lakeward west breakwater extension, a 

 150-ft-long shoreward east breakwater extension, and segmented wave 

 absorbers adjacent the harbor side of the west breakwater was com- 

 pleted (Figure 257) . The modifications were constructed of rubble- 

 mound materials. The west breakwater extension consisted of a 

 structure with a crest el of +11 ft Iwd, a crest width of 12 ft, side 

 slopes of 1V:1.5H, and armor stones ranging from 7.5 to 16 tons. The 

 east shoreward extension had an el of +8 ft Iwd, a crest width of 

 8 ft, side slopes of 1V:1.5H, and armor stones ranging from 1.2 to 

 2.5 tons. The modifications were model tested prior to construction 

 (Bottin 1984). 



1986 The structures are presently in good condition. An aerial photo of 

 the Barcelona Harbor breakwaters is shown in Figure 258.
