Huron, Ohio 



Date(s) Construction and Rehabilitation History 



1827- Construction of an 800-ft-long west pier (Figure 210, Section A) was 

 1831 completed. The pier was a 20-ft-wide stone-filled timber crib struc- 

 ture (Figure 211, Section A). 



1891- A 973-ft-long extension of the west pier (Figure 210, Sections C and 

 1894 G) was completed. The extension consisted of a stone-filled timber 



crib structure that ranged from 16 to 20 ft in width (Figure 211, 



Section C) . 



1907- Construction of a 1 ,450-ft-long rubble-mound east breakwater (Fig- 

 1908 ure 210, Section B) was completed during this time. The breakwater 

 had a crest width of 10 ft and an el of +10.3 ft Iwd (Figure 212, 

 Section B) . Side slopes were IV: 2H on the lakeside and IV: 1.34 on 

 the harbor side. A concrete and stone superstructure was installed 

 on a portion of the west pier (Figures 210 and 211, Section C) also 

 during this period of time. The crest el of the pier was +8.3 ft 

 Iwd. 



1914 A 280-ft-long shoreward extension of the west pier (Figure 210, Sec- 

 tions D and F) was completed. The lakeward portion of the extension 

 involved woodpilings driven about 15 ft apart and filled with stone 

 (Figure 212, Section D) , The extension was capped with larger stone 

 (5-ton minimum) and had a crest el of about +6.0 ft Iwd. The adja- 

 cent 160-ft-long shoreward portion of the extension (Figure 212, 

 Section F) was a rubble-mound structure with a crest width of 5 ft 

 and an el of +5 ft Iwd. Side slopes were IV: IH. 



1925 A concrete superstructure was installed on an 800-ft-long portion of 

 the west pier (Figures 210 and 211, Section A). The crest el of this 

 portion of the pier was +6.3 ft Iwd. 



1930 The shoreward rubble-mound portion of the west pier constructed in 

 1914 (Figures 210 and 212, Section F) was repaired and extended 

 shoreward an additional 110 ft. 



1933- A 1,360-ft-long rubble-mound extension of the west pier (Figure 210, 

 1934 Section E) was constructed during this period. The breakwater had a 

 crest width of about 8 ft and an el of +8 ft Iwd. Side slopes were 

 1V:1.3H (Figure 211, Section E) . Armor stones with a minimum weight 

 of 3 tons, and not less than 50 percent being 5 tons or more, were 

 used. 



1950 A 242-ft-long portion of the west pier was repaired by encasing it 

 with steel sheetpiling (Figures 210 and 211, Section C) . The voids 

 between the sheetpiling and the existing structure were filled with
