 Philadelphia District 



Date(s) Construction and Rehabilitation History 



1908 A 1 ,263-ft-long stone-filled timber crib jetty was constructed on the 

 west side of the inlet. 



191 1- Stone replacement repairs were made each of these years. Cause 



1914 of damage was due to inadequate jetty design; waves easily damaged 



1917, the timber cribs. The cribs were also permeable to sand. 



1920, 



1923 



1937 The timber crib jetty was replaced by two steel sheet-pile jetties, 

 constructed 500 ft apart, on the east and west sides of the inlet. 

 Both jetties were 1,700 ft long (Figure 36). Crest elevations were 

 +8.0 ft mlw, except the shoreward ends which were +10.0 ft mlw. 



1939 The jetties had deteriorated due to corrosion. 



1944 The jetties were flanked and rubble was placed along the east bank. 

 The additional rubble extended the east jetty shoreward 400 ft. The 

 possibility of the west jetty becoming completely flanked was 

 determined to be remote; therefore, no rubble was placed on the west 

 bank. Seaward ends of both jetties were repaired due to 

 deterioration by corrosion. 



1985 The jetties are in poor condition and are ineffective. They are 

 considered a navigation hazard and are to be removed.
