Charlevoix, Michigan 



Date(s) Construction and Rehabilitation History 



1872 Construction of a north pier (Figure 163, Section B) was completed. 

 The structure was a 20-ft-wide stone-filled timber crib. 



1879- Construction of the lakeward portions of the north and south piers 

 1880 (Figure 163, Sections A and A-1) was completed. The piers consisted 



of stone-filled timber crib structures (Figure 164, Sections A and 



A-1) that were 20 ft in width. 



1882 Construction of a shoreward portion of the south pier (Figure 163, 

 Section F) was completed. The pier consisted of woodpilings driven 

 approximately 20 ft apart (Figure 16A, Section F) and filled with 

 stone. 



1897 Rubble was placed along the lakeside and over the shoreward portion 

 of the north pier (Figure 163, Section B) . The crest width of the 

 rubble structure (Figure 164, Section B) was 10 ft, and it had an el 

 of +8.1 ft Iwd. Side slopes were 1V:2H, and the cover stone used was 

 1,000 lb (min). 



1930 The shoreward portion of the south pier (Figure 163, Section F) was 

 repaired and capped with a concrete and stone superstructure (Fig- 

 ure 164, Section F) . The crest el of the pier was +7.1 ft Iwd. 



1942 The lakeward portions of the north and south piers (Figure 163, Sec- 

 tions A and A-1) were capped with concrete and stone superstructures 

 (Figure 164, Sections A and A-1) with crest els of +7.0 ft Iwd. 



1966 The lakeward portion of the existing north pier (Figure 163, Sec- 

 tion A-1) was repaired by encasing it between steel sheetpiling 

 spaced 33 ft apart (Figure 164, Section A-1). The voids between the 

 steel sheetpiling and the existing timber crib were filled with stone 

 and capped with concrete to an el of +6.75 ft Iwd. A 35-ft-diameter 

 steel sheet-pile cell was constructed at the head of the north pier 

 (Figures 163 and 164, Section A-2) . The pier head was filled with 

 stone and capped with concrete at an el of +7 ft Iwd. Steel sheet- 

 piles were also installed on each side of the shoreward portion of 

 the south pier (Figures 163 and 164, Section F) . On the channel side 

 the void was filled with stone, and the crest was grouted at an el of 

 +6.5 ft Iwd. 



1971 Replenishment of fill stone was performed on the lakeward portion of 

 the south pier (Figure 163, Section A). 



1981 Portions of the north (Figure 163, Sections A and B) and south (Fig- 

 ure 163, Section A) piers were rehabilitated. The existing timber
