Burlington Harbor Breakwater 



Burlington, Vermont 



New York District 



Date(s) Construction and Rehabilitation History 



1890 A 4,157-ft breakwater was completed after 54 years of construction 

 (Figure 8). The breakwater consisted of two segments at lengths of 

 364 ft (north) and 3,793 ft (south) which were separated by 250 ft. 

 Construction was of rubble mound resting on rock-filled timber cribs 

 capped by either concrete (2,457 ft), or rock (1,700 ft). The cribs 

 rested on a sand and gravel bed and were fastened with dowels and 

 tenons. Crest elevation was +8.0 ft low lake level (111), and crib 

 width ranged from 24 to 34 ft. 



1948 The breakwater was repaired. Stone was placed on the lakeside at 

 weakened sections. 



1960 A survey indicated the existing structure had settled 1.0 to 3.0 ft 

 along the entire length. Deterioration of sections of the timber 

 fasteners left unconnected sections and caused timber displacement 

 and leaning of the structure lakeward. Deterioration was believed to 

 be caused by wave action and ice conditions over long periods of 

 time. Approximately 550 lin ft of the stone superstructure was un- 

 dermined. Eighty feet of the structure was breached. 



1962- The breakwater was rehabilitated using 16,573 tons of stone at a cost 

 1965 of $381,000. 



1986 No further repair or maintenance information has been found.
