Conneaut, Ohio 



Date(s) Construction and Rehabilitation History 



1894 Construction of the east and west piers (Figure 246) was completed. 

 The piers were constructed of stone-filled timber cribs. (Fig- 

 ures 246, 247, 248, and 249 illustrate structures at Conneaut Har- 

 bor.) The east pier was 18 ft wide (Figure 247), and the west pier 

 was 24 ft wide (Figure 249) . 



1905- The east and west piers were capped with concrete superstructures 

 1907 during this period. The east pier had a crest el of +8.3 ft Iwd 



(Figure 247) , and the west pier superstructure was installed at an el 

 of about +6.1 ft Iwd (Figure 249). The Corps of Engineers presently 

 maintains only the lakeward 300-ft-long section of the west pier. A 

 1 ,054-ft-long portion of the east breakwater (Figure 246, Section C) 

 also was constructed during this time. The breakwater was a 23-ft 

 wide stone-filled timber crib. A concrete superstructure with a 

 crest el of +10.3 ft Iwd was included along with a rubble slope on 

 the lakeside (Figure 247, Section C) . 



1911- An 810-ft-long rubble-mound shoreward extension of the east break- 

 1912 water (Figure 246, Section A) was completed. The extension had a 



crest el of +10 ft Iwd and a crest width of 10 ft (Figure 247, Sec- 

 tion A). Side slopes on the lakeside were 1V:1.5H, and 1V:1.3H on 

 the harbor side. Armor stones greater than 3 tons each were used in 

 construction. 



1912- A 3,403-ft-long rubble-mound west breakwater (Figure 246, Sections A 

 1917 and I) was constructed during this time. Breakwater cross sections 



were similar to those used for the east breakwater extension built 

 during 1911-1912 (Figure 247, Section A, and Figure 248, Section I). 



1916- Construction of an 886-ft-long rubble-mound lakeward extension of the 

 1923 east breakwater (Figure 246, Section B) was completed during this 



time. The structure cross section was similar to the shoreward ex- 

 tension of the east breakwater completed during 1911-1912 (Fig- 

 ure 247, Section B) . 



1934- Construction of a 935-ft-long rubble-mound lakeward extension of the 

 1936 east breakwater (Figure 246, Section G) ; an 865-ft-long rubble-mound 

 lakeward extension of the west breakwater (Figure 246, Section F) ; 

 and a 1 ,670-f t-long rubble-mound shore arm of the west breakwater 

 (Figure 246, Section H) was completed. The lakeward extensions had 

 10-ft crest widths and crest els of +10 ft Iwd (Figure 248, Sections 

 F and G) . Side slopes were 1V:1.3H, and armor stone had a minimum 

 weight of 3 tons with not less than 50 percent of 5 tons or more.
