Date(s) Construction and Rehabilitation History 



1954- Reconstruction of 45 ft of the lakeward end of the south pier (Fig- 

 1958 ure 71, Section Dl) occurred during this period. Steel sheetpiling 

 was installed on each side of the existing structure forming a pier 

 width of 26.5 ft (Figure 72, Section Dl). The voids were filled with 

 gravel and stone, and a concrete superstructure was installed at an 

 el of +8.0 ft Iwd. Riprap toe protection was installed on each side 

 of the structure. 



1956 A 211-ft-long inner portion of the south pier (Figure 71, Section E) 

 was constructed. The pier section consisted of steel sheetpiling 

 installed adjacent to the shoreline at an el of +7 ft Iwd and back- 

 filled with earth (Figure 72, Section E) . Riprap was placed along 

 the toe of the structure. 



1966 A 969-ft-long portion of the south pier was reconstructed (Figure 71, 

 Sections B and D) . Steel sheetpiling was installed on each side of 

 the existing pier a distance of 26.75 ft apart. The void between the 

 sheet pile was filled with stone, and a concrete superstructure was 

 installed (Figure 72, Sections B and D) at an el of +7.67 ft Iwd. 



1983 A site inspection revealed that the structures were generally in good 

 condition. Minor concrete repairs and the placement of additional 

 riprap were recommended for the north breakwater. The work has sub- 

 sequently been completed. It was noted also that settlement of the 

 north pier on the channel side had occurred. 



1986 During their lifetime the structures have undergone reconstruction 

 and normal maintenance repairs. Presently they are considered in 

 good condition.
