stone and a concrete cap was installed. The width of the pier varied 

 from 24 to 28 ft, and the crest el ranged from +8.4 to +9.4 ft Iwd. 



1957 A 341-ft-long portion of the west pier was repaired (Figures 210 and 

 211, Section C) in the same manner as the 1950 repairs. 



1963 A 390-ft-long portion of the west pier was repaired (Figures 210 and 

 211, Section G) in a manner similar to the 1950 and 1951 repairs. 

 The structure width, however, was 34.7 ft, and the crest el was 

 +8.75 ft. 



1975 Reconstruction of the portion of the west pier adjacent to the Corps 

 disposal area (Figure 210) was completed. The rubble- mound portion 

 of the pier (Section E) was raised to an el of +15.25 ft Iwd and had 

 a crest el of 8 ft (Figure 211). The steel sheet-pile encased por- 

 tion of the pier (Sections C and G) included the installation of 

 stone adjacent to the containment side of the pier (Figure 211). The 

 crest el of the stone structure was 10.25 ft Iwd, and the crest width 

 was 8.5 ft. A parapet was installed at an el of +11.0 ft on the en- 

 cased structure adjacent to the stone crest. 



1984 Many repairs have been performed during the structure's lifetime, and 

 they are considered to be in fair condition. An aerial photo of the 

 Huron Harbor structures is shown in Figure 213.
