Grand Haven Harbor Piers 



Grand Haven, Michigan 



Date(s) Construction and Rehabilitation History 



1867- Construction of the shoreward 396 ft of the south pier (Figure 126, 

 1869 Sections K, Jl, and J) was completed during this period. The pier 

 consisted of timber piling spaced approximately 30 ft apart and 

 filled with stone (Figure 128, Sections K, Jl, and J). 



1875- Construction of the shoreward 605 ft of the north pier (Figure 126, 

 1879 Section B) was completed during this time. The pier was constructed 



with a 30-ft-wide stone-filled timber crib structure (Figure 127, 



Section B) . 



1882- The south pier was extended by 1,000 ft (Figure 126, Sections HI and 

 1887 I) . This extension consisted of stone-filled timber crib structures 



(Figure 128, Sections HI and I) built on a stone base. The cribs 



were about 30 ft wide. 



1887- The south pier was extended by 119 ft (Figure 126, Section H) and the 

 1894 north pier by 811 ft (Figure 126, Sections A, Al, and A2) during this 

 time. The extensions were constructed with stone-filled timber cribs 

 on stone bases (Figure 127, Sections A, Al , and A2; and Figure 128, 

 Section H) . The width of the structures were 30 ft. 



1916- The north and south piers (Figure 126) were capped with stone and 

 1922 concrete superstructures during this period. The north pier (Fig- 

 ure 127, Sections A, Al , A2, and B) ranged in el from +7.1 to +8.0 ft 

 Iwd, and the south pier (Figure 128, Sections H, HI, I, J, Jl, and K) 

 had a crest el ranging from +6.3 to 9.1 ft Iwd. 



1952- The north and south piers (Figure 126) were repaired during this 

 1960 time. The existing structures were encased in steel sheetpiling 

 (Figures 127 and 128) . The voids between the sheetpiling and the 

 existing structures were filled with gravel or stone, and the pier 

 edges were capped with concrete. The north pier ranged from about 34 

 to 36 ft in width (Figure 127, Sections A, Al , A2 , and B) , and the 

 south pier was from 37 to 51.5 ft in width (Figure 128, Sections H, 

 HI, I, J, Jl, and K). 



1976 Riprap stone was placed along the outer 210 ft of the lakeside por- 

 tion of Section H-1 (Figure 126) of the south pier. Fill stone also 

 was replenished in the cells of Section K of the south pier, and they 

 were capped with concrete. 



1980 Riprap was placed along portions of the north (Figure 126, Sections A 

 and Al) and south (Sections J, Jl, and H) piers.
