Philadelphia District 



Date(s) Construction and Rehabilitation History 



1903 Construction of two rubble-mound jetties, north and south of the 



canal, was completed to provide channel protection. The length of 

 each jetty was 725 ft, crest elevations were +8.0 ft mlw, crown 

 widths were 6.0 ft, and side slopes were 1:1 (Figure 32). 



1938 Each jetty was extended to 2,095 ft (Figure 32). 



1960's The south jetty was removed and replaced by a new jetty to increase 

 the entrance size to accommodate larger vessels and to improve 

 navigation safety. The new jetty had a crest elevation of +8.0 ft 

 mlw and a 14.0-ft crown width (Figure 32). The design wave was 

 6.3 ft, 4.8 sec. 



1985 The north jetty has subsided, lost stone, and the toe has scoured.
