Lake Ontario Shoreline Hazard Management Plan Update

In 1990, the Central Lake Ontario (CLOCA), Lower Trent Region (LTRCA) and Ganaraska Region (GRCA) Conservation Authorities completed a Lake Ontario Shoreline Management Plan to guide shoreline management within their respective jurisdictions.


Zuzek Inc. and SJL Engineering Inc. were retained by the Central Lake Ontario (CLOCA), Ganaraska (GRCA) and Lower Trent Region (LTRCA) Conservation Authorities to develop an updated Shoreline Management Plan (SMP) for their respective Lake Ontario shorelines. The SMP replaces the original SMP for the region, which was prepared in 1990 by Sandwell Swan Wooster (SSW, 1990). The total shoreline length covered by the SMP is approximately 135 km and stretches from Lakeside Neighbourhood Park in Ajax (CLOCA west boundary) to Carrying Place, Quinte West (LTRCA east boundary).

The key objectives of the SMP are to increase the resilience of coastal communities, protect new development from coastal hazards, update existing hazard mapping using the best available information, incorporate nature-based solutions, protect and enhance existing private and public amenities along the shoreline, and to integrate climate change impacts when considering the coastal hazards of the future.
