Kenosha Harbor Structures 



Kenosha, Wisconsin 



Date(s) Construction and Rehabilitation History 



1899- Construction of a 1 ,077-f t-long portion north pier, a 1 , 175-f t-long 

 1900 south pier, and a 796-ft-long offshore breakwater was completed 



(Figure 91). The shoreward 927 ft of the north pier consisted of a 

 wood-pile structure with widths of 14 ft (Figure 92, Section A) and 

 18 ft (Section B) . The outer 150-f t-long portion of the north pier 

 (Figure 92, Section C) , the south pier (Figure 92, Section E) , and 

 the offshore breakwater (Figure 92, Section H) were stone-filled 

 timber crib structures. Riprap toe protection was installed on each 

 side of the timber cribs. 



1916 Stone and concrete superstructures were constructed on the north and 

 south piers to an el of +6.8 ft Iwd (Figure 92, Sections A, B, C, and 

 E). 



1923 A stone and concrete superstructure was built on the detached 



breakwater (Figure 92, Section H) to a crest el of +7.1 ft Iwd. The 

 structure was 30 ft wide. 



1969- The north and south piers were rehabilitated during this time 

 1970 (Figure 92, Sections A, B, C, and E) . Steel sheetpiling was driven 

 on each side of the north pier resulting in a structure 30 ft wide. 

 Voids were filled with stone, and a concrete cap was installed at a 

 crest el of +8.5 ft. Riprap was installed on each side of the 

 structure. Steel sheetpiling was installed on the lakeward side of 

 the south pier. The void and the existing pier were filled with 50- 

 Ib stone. A parapet wall was installed on the lakeward side of the 

 structure to an el of +10 ft Iwd. (This was adjacent to a confined 

 dredging disposal area) . 



1977 The detached breakwater (Figure 92, Section H) was rebuilt, and 1- to 

 6-ton (3-ton average) riprap stone was placed on each side of the 

 structure to an el of +4 ft Iwd. Side slopes of the riprap were 

 1V:1.5H. 



1980 A site inspection of the structures revealed them to be generally in 

 good condition. Spalling of concrete was noted in several areas; 

 however, the problem was not critical at that time. 



1986 The structures presently are considered to be in fair condition.
