Date(s) Construction and Rehabilitation History 



1927 Portions of the north (Figure 110, Sections C and D) and the south 

 pier (Figure 110, Section I) were capped with concrete and stone 

 superstructures. The crest el of the north pier was +7.0 ft Iwd 

 (Figure 112, Sections C and D) and the south pier had an el of 

 +7.5 ft Iwd (Figure 113, Section I). 



1931 The lakeward end of the north pier (Figure 110, Sections Al , A2, A3, 

 AA, A, and B) were capped with a concrete superstructure (Figure 111, 

 Sections Al , A2, A3, A4, and A, and Figure 112, Section B) . 



1934 A 376-ft-long portion of the south pier (Figure 110, Section G) was 

 capped with a concrete superstructure (Figure 112, Section G) . 



1941 The shoreward portion of the south pier (Figure 110, Sections J, K, 

 and L) was capped with a concrete superstructure on the channel side 

 (Figure 113, Sections J, K, and L) . The crest el of the cap was 

 7.0 ft Iwd, and it was backfilled with earth and stone. 



1952- Portions of the north pier (Figure 110, Sections Al and A2) were 

 1953 repaired by enclosing the structure in a steel sheetpiling encase- 

 ment (Figure 111, Sections Al and A2) . Voids were filled with con- 

 crete, and the pier was recapped with concrete. The outer portion 

 (Section Al) had a crest el of +8.0 ft iwd and was 35.5 ft wide, 

 while the other portion (Section A2) was +7.1 ft Iwd with a width of 

 35.5 ft. Riprap toe protection was also Installed on each side of 

 the piers adjacent to the new sheet-pile walls. 



1961 Additional portions of the north pier were repaired (Figure 110, 



Section A4, C, D, and E) by using steel sheetpiling. The shoreward 

 portions of the pier were repaired by installing sheetpiling on the 

 channel sides of the existing structures (Figure 112, Sections C, D, 

 and E) and backfilling the voids with stone prior to capping the area 

 with concrete. The el of this portion of the pier was +7.0 ft iwd. 

 The remaining portion of the pier was repaired by enclosing the 

 structure in a steel sheet-pile encasement (Figure ill. Section A3). 

 Voids were filled, and the structure was capped with concrete to an 

 el of about +7.6 ft Iwd, The pier width was approximately 36 ft. 



1963 A portion of the north pier (Figure 110, Section A4) and a portion of 

 the lakeward end of the south pier (Figure 110, Section F) were re- 

 paired by enclosing the structures in steel sheetpiling encasements 

 (Figure 111, Section A4 and Figure 112, Section F) . Voids between 

 the sheetpiling were filled with stone, and the piers were capped 

 with concrete. The structures were about 36 ft wide and had crest 

 els of approximately 7.0 ft Iwd after repairs wore made. Riprap toe 

 protection was also installed on each side of the piers.
