Date(s) Construction and Rehabilitation History 



The west breakwater shore arm had a crest el of +8 ft Iwd and a width 

 of 10 ft and 1-V:1.3-H side slopes (Figure 248, Section H) . Armor 

 stone sizes were the same as those on the lakeward breakwater 

 extensions. 



1941- Rehabilitation of a 1 ,251-f t-long portion of the west breakwater 

 1954 (Figure 246, Section I) was performed. The structure was built up 

 with additional stone to a crest el of +10 ft iwd and a crest width 

 of 8 ft (Figure 248, Section I). Side slopes of 1V:1.3H were used, 

 and armor stone with a minimum weight of 3 tons and not less than 

 50 percent of 5 tons or more was placed. 



1954- A 1 ,552-f t-long portion of the west breakwater trunk was rehabili- 

 1960 tated by the installation of additional stone to its original design 

 (Figures 246 and 247, Section A). 



1963- Rehabilitation of a 600-ft-long portion of the west breakwater (Flg- 



1964 ures 246 and 247, Section A) and an 800-f t-long portion of the east 

 breakwater (Figures 246 and 247, Sections B and C) was completed. 



The rubble-mound portions of the breakwaters were repaired by the in- 

 stallation of additional stone to original design specifications. 



1965 A 1 , 187-f t-long cellular steel sheet-pile shoreward east breakwater 

 extension (Figure 246, Sections J and K) was constructed. The cells 

 were granular filled (Figure 249, Sections J and K) and had diameters 

 of about 30.2 (Section J) and 20.7 ft (Section K) . They were capped 

 with concrete at an el of +10 ft Iwd. Model testing was conducted 

 prior to the construction of this extension (Hudson and Wilson 1963) . 



1983 Maintenance repair to the west breakwater was performed for a cost of 

 about $310,000. 



1986 The structures are presently considered to be in fair condition. The 

 concrete cap in the midsection of the east breakwater (Figures 246 

 and 247, Section C) , particularly, is in need of repair. An aerial 

 view of the Conneaut Harbor structures is shown in Figure 250.
