Ocean City Inlet Jetties 



Ocean City, Maryland 



Baltimore District 



Date(s) Construction and Rehabilitation History 



1934 a 1 , 100-ft-long jetty was constructed on the north side of a newly 

 formed inlet at Ocean City (Figure 62). Crest elevation was +4.0 

 mlw, crown width was 12.0 ft, and side slopes were 1V:2H from the 

 crest to -4.0 mlw and 1V:1.5H from -4.0 mlw to the bottom. 



1935 Construction was completed on a jetty on the south side of the inlet. 

 Crest elevation was +6.0 ft mlw, and crown width was 12.0 ft. The 

 landward 750 ft of the jetty was 1,100 ft south of the north jetty. 

 The south jetty angled north 1,100 ft to a point 600 ft from the 

 north jetty. The final 530 ft of the south jetty was parallel to 

 that of the north jetty. The crest elevation decreased from +6.0 ft 

 mlw to the apron elevation beginning 170 ft seaward of this final 

 section. The apron extended 200 ft farther seaward. The total 

 length of the jetty was 2,380 ft, including the apron. A total of 

 39,500 tons of stone was used for core; 17,300 tons were used for 

 capstone on the south jetty. 



1937 Sand on the north side of the north jetty had reached the top of the 

 jetty and was depositing in the inlet. A concrete superstructure was 

 built to raise the jetty elevation. The first 100 ft from the 

 boardwalk was raised to +12.0 ft mlw, the next 254 ft was raised to 

 +9.0 ft, and the next 170 ft was raised to +7.0 ft mlw. 



1956 Repairs were made on the seaward 750 ft of the north jetty because of 

 slope failures on the channel side from toe scour. The existing con- 

 crete cap was repaired and raised to +9.0 ft. Armor stone was placed 

 on the seaward 575 ft. The armor stone section was placed 26 ft 

 north of the center line to use existing stone as toe protection and 

 to minimize the stone required. The landward end of the south jetty 

 was repaired to maintain integrity with the shoreline. 



1963 Approximately 720 ft of the south jetty was rehabilitated due to 



slope failures caused by a scour hole that had an elevation of -37 ft 

 mlw. Armor stone was placed 25 ft seaward of the center line for the 

 same reasons stated above in positioning the north jetty. The land- 

 ward end of the south jetty was again repaired to maintain integrity 

 with the shoreline. 



1984 The seaward 1,100 ft of the south jetty was rehabilitated due to 



slope failures. The section repaired in 1963 had deteriorated. The 

 scour hole had a maximum depth of -54 ft mlw. Repairs consisted of 

 filling the scour hole with dredged material to -20 ft mlw, covering 

 the hole with 18 in. of blanket stone, and placing stone berm quarry 

 run and armor stone along the toe on the channel side of the
