Construction of a 620-ft-long north pier and a 790-ft-long south pier 

 (Figure 152) was completed by private interests. The north pier is a 

 stone-filled timber crib, and the south pier consists of stone-filled 

 timber cribs and steel sheetpiling with concrete caps. The outer end 

 of the south pier is a 20-ft semicircular steel sheet-pile cell with 

 a concrete cap. 



Maintenance of the project by the Corps was authorized. Maintenance 

 of the piers prior to this time was performed by private interests 

 and the Michigan Department of Natural Resources. 



Riprap stone was placed along and into the water along 490 ft of the 

 north pier which was in a very poor to failed condition. 



Fill stone was placed in the steel sheet-pile cell at the head of the 

 south pier, and riprap stone was placed around and on top of the 

 cell. A 35-ft breached area and a 10-ft breach near the shoreline 

 of the south pier also were repaired with fill/core and riprap stone. 



An inspection of the site indicated settled and/or washed out stone 

 in numerous areas of the north pier. Water is washing through the 

 voids of the structure, and three areas are nearly breached. The 

 steel sheet-pile cell at the head of the south pier is completely 

 broken out, and most of the grout cap along the entire length of the 

 pier is missing with stone being washed out. The condition of the 

 piers is very poor, and immediate reconstruction/rehabilitation has 

 been recommended.
