Construction and Rehabilitation History 
damage with numerous gaps (exposed core) at its landward end, from 
sta 10+00 to sta 18+00, and seaward of sta 141+00. The south jetty 
needed repairs seaward of 279+00. Estimated stone quantities needed 
to repair the north and south jetties were 46,000 (reset 38,000) and 
4,200 (reset 1,000) tons, respectively. 
During 1925-1926, the full length of the north jetty was repaired 
using 44,000 tons of stone at a cost of $305,000. The seaward end of 
the south jetty between sta 293+00 and sta 354+00 was repaired in 
1927. Cost for placing 5,200 tons of stone was $47,600. 
A total of 430 tons of cover stone was placed on the south jetty. 
An asphaltic concrete cap was placed on portions of both jetties, and 
a concrete cap was placed between sta 0+00 and sta 20+00 at the north 
jetty's landward end. The majority of the asphaltic cap was placed 
on two sections of the south jetty, near the existing shoreline from 
sta 196+55 to sta 230+59 and near the outer end from sta 345+08 to 
sta 347+98. The north jetty was capped at two existing low points or 
gaps from sta 144+15 to sta 145+75 and sta 177+00 to sta 178+00. 
Prior to the cap a seal course of asphaltic concrete was placed in 
the void spaces. The cap had a crown elevation of +4.7 ft, a crown 
width of 8 ft, and 1V:1H side slopes. The capping cost was $135,000 
and used 12,280 tons of asphalt. The north jetty concrete cap was 
placed to an elevation of +6.5 ft mlt, an 8-ft crown width, and ver- 
tical sides. Stone totaling 9,200 tons also was placed at the north 
jetty's inner end bringing the total cost to $82,700. 
Repairs were made to the north jetty with 15- to 150-lb core stone 
and 6- to 10-ton cover stone placed between sta 135+00 and sta 253+00 
(near seaward end). A total of 22,300 tons of stone (87 percent 
cover) was placed and 600 cover stone reset. A concrete cap was 
placed on the south jetty from sta 230+59 to sta 251+12. The rec- 
tangular cap was 8 ft wide and had a crest elevation of +6 ft mlt. 
The cap required 800 tons of chinking riprap and 3,163 cu yds of con- 
crete. The seaward section of the south jetty asphalt cap was de- 
stroyed during heavy wave action in 1941. About 7,000 tons of cover 
stone were placed at this section and other damaged areas. Total 
cost of the capping and armor stone repairs was $65,300 and $264,400, 
respectively. 
The shore end of the north jetty was repaired using 610 tons of core 
stone for a total cost of $5,700. 
The north jetty was rehabilitated from sta 8+00 to sta 229+00, and 
the south jetty was rehabilitated from sta 251+13 to sta 354+00. 
Stone was placed on the gulf side slope and crown of each jetty
