Date(s) Construction and Rehabilitation History ^^ 



1931- Extensive repairs were made to the outer ends of both jetties. 



1932 Precast concrete blocks (4 by 9 ft) were used in lieu of stone and 

 piled one on top of another for constructing the forms for concrete 

 monoliths. North jetty repairs using 1,200 cu yd of concrete* were 

 completed in 1931 at a cost of $53,246. In 1932 north jetty re- 

 pairs using 266 cu yd of concrete and south jetty repairs using 

 15,986 cu yd of concrete were completed for $247,038. 



1933 North jetty repairs using 4,748 cu yd of concrete and 6,435 tons of 

 stone and south jetty repairs using 926 cu yd of concrete were com- 

 leted for $105,932. 



1935 North jetty repairs using 1,370 cu yd of concrete were completed at 

 a cost of $17,366. 



1936 North jetty repairs using 1,203 cu yd of concrete and south jetty 

 repairs using 1,209 cu yd of concrete were completed at a cost of 

 $28,933. It was determined by this time that the rectangular con- 

 crete blocks were moved easily by the sea. Large stone, however, 

 was not obtainable at a reasonable price and was replaced by con- 

 crete blocks. When placed in the parapet, the blocks were con- 

 creted in place. 



1937 South jetty repairs using 1,552 cu yd of concrete were completed at 

 a cost of $25,400. 



1939 Heavy storms caused great damage to both jetties. The monoliths at 

 the outer end of the south jetty were undermined, causing them to 

 tilt and sink. Breaches occurred in the jetty immediately shore- 

 ward of the monolithic end. A partial breach occurred through the 

 north jetty just shoreward of its monolithic end. In addition, 

 considerable damage was done to the side slopes of both jetties. 

 During the year south jetty repairs were completed using 



12,450 cu yd of concrete at a cost of $151,025. 



1940 North jetty repairs using 7,418 cu yd of concrete and 2,200 tons of 

 stone and south jetty repairs using 29,772 cu yd of concrete were 

 completed at a cost of $311,848. 



1941 North jetty repairs using 15,158 cu yd of concrete and 1,705 tons 

 of stone were completed at a cost of $141,220. 



1942 North jetty repairs using 8,809 cu yd of concrete were completed 

 for a cost of $124,220. 



1943 North jetty repairs using 7,560 cu yd of concrete and south jetty 

 repairs using 2,550 cu yd of concrete were completed at a cost of 

 $189,812.

Concrete used for jetty repairs was mass poured unless otherwise noted,
