With record high water levels experienced in Lake Ontario in 2017 and 2019, McIntosh Perry and ShorePlan Costal Engineering Consultants undertook a Preliminary and Detail Design study of the condition of the predominantly limestone shoreline adjacent to Highway 33 (Loyalist Parkway) between the Glenora Ferry terminal in Adolphustown and Collins Bay in Kingston. Recent high water levels and waves generated by storms accelerated erosion and failure of shore protection structures, requiring emergency repairs.
Priority for shore protection works was established by the risk to the highway from erosion and flood risk from wave overtopping. Based on this study, over 20 areas were identified for shoreline stabilization.
McIntosh Perry Engineers collaborated to prepare the construction tender for repairs the most vulnerable segments of the shoreline using armour stone walls, boulder berms and other revetments. Given the diverse fish species in Lake Ontario, this project involved extensive consultation the Department of Fisheries and Oceans.
