White Lake Harbor Piers 



White Lake, Michigan 



Date(s) Construction and Rehabilitation History 



1870- A 495-ft-long north pier was constructed at the site (Figure 134, 

 1872 Section G) during this time frame. The pier was constructed of wood- 

 pilings driven from 21 to 29 ft apart and filled with stone (Fig- 

 ure 135, Section G) . 



1899 A 673-ft-long south pier (Figure 134, Sections C, D, and E) was con- 

 structed. The inner 369 ft was constructed with woodpilings (Fig- 

 ure 135, Sections D and E) . The piers were stone filled and ranged 

 in width from 22 to 26.5 ft. The outer 304-ft-long portion (Fig- 

 ures 134 and 135, Section C) consisted of a stone-filled timber crib 

 structure that ranged from 28 to 30 ft in width. 



1900 The north and south piers were extended by 200 and 150 ft, respec- 

 tively (Figure 134, Sections A and B) . The extensions were stone- 

 filled timber crib structures and were built on a stone base (Fig- 

 ure 135, Sections A and B) . The north pier (Section A) was 24 ft in 

 width, and the south pier (Section B) was 34 ft wide. 



1936- The north and south piers were capped with concrete and stone super- 

 1937 structures (Figure 135, Sections A-E and G) . The crest els of the 

 pier were +7.0 ft Iwd. 



1971 Fill stone was replenished in the shoreward portion of the north pier 

 (Figure 134, Section G) . An underwater examination of the lakeside 

 of the south pier revealed signs of deterioration of the timber 

 piling along Sections C and D (Figure 134) and fill stone being 

 washed out between these pilings. 



1982 Fill stone was replenished in the lakeward portion (Figure 134, Sec- 

 tion A) of the north pier and the south pier (Figure 134, Section B) . 

 Riprap stone around the head of the south pier (Section B) also was 

 placed. 



1983 Riprap stone around the heads and along the lake and channel sides of 

 Section A (Figure 134) was placed. In addition, stone fill was again 

 placed in open pockets of the superstructures of this portion of the 

 pier and grouted over. 



1985 An inspection of the structures indicated that the substructures of 

 both piers are deteriorating, resulting in superstructure settlement 

 and cracking, considerable misalignment and tilt, and loss of fill 

 stone. Both structures are considered to be in poor condition. 

 Reconstruction and/or rehabilitation has been recommended within the 

 next 2 to 3 years.
