Date(s) Construction and Rehabilitation History 



1940 Construction of the north pier (Figure 88, Sections K and L) was com- 

 pleted. The inner 105-ft-long portion was a timber crib structure 

 with a sand cap. It was 24.5 ft wide and had a crest el of +7.5 ft 

 Iwd (Figure 89, Section K) . The outer 75 ft of the pier (Section L) 

 was a wood-pile structure that was 19.5 ft in width and +7.5 ft Iwd 

 in height. It was capped with stone. 



1959 A 252-ft-long portion of the north breakwater was repaired (Fig- 

 ure 88, Section C) . 



1966 A 50-ft-long portion of the south breakwater was constructed (Fig- 

 ure 88, Section G-1). The breakwater was built with stone and had a 

 14-ft-width crest with an el of +7.1 ft Iwd. Side slopes were 

 1V:1.5H. The stone along the crest was grouted in place. 



1971 The shoreward 1,104 ft of the south breakwater (Figure 88, Sections B 

 and G) were repaired, and riprap was installed on each side of the 

 structure to an el of +4 ft Iwd (Figure 89, Sections B and G) . Side 

 slopes of the riprap were 1V:1.5H. 



1973 The lakeward 796-ft-long portion of the north breakwater was repaired 

 (Figure 88, Section F) . Riprap was installed on each side of the 

 structure (Figure 89, Section F) to an el of +4 ft Iwd. The riprap 

 was placed with side slopes of 1V:1.5H. 



1974 Two sections of the north breakwater (Figure 88, Sections A' and B') 

 were rebuilt. Steel sheetpiling was driven on the lakeward side of 

 the 183-ft-long portion of Section A' (Figure 90). Filling the voids 

 with stone and capping the breakwater with concrete resulted in a 

 breakwater section that was 17.5 ft in width with a crest el of 



+7.5 ft Iwd. The 60-ft-long portion of Section B' (Figure 90) was 

 covered with stone. It had a 15-ft-wide crest with an el of +7.1 ft 

 Iwd. Concrete was poured between the stones on the crest to form a 

 walking surface. The existing concrete superstructure was removed 

 because of its deteriorated condition prior to placement of the 

 stone. Side slopes of the structure were 1V:1.5H. 



1986 The structures have undergone repair and maintenance during their 

 lifetime; however, they are presently in good condition. The 

 President signed an act to deauthorize the project at Racine, and the 

 title to any facilities constructed by the United States has been 

 transferred, without consideration, to Racine County.
