Great Lakes Hazards Planning: Experience from Southeastern Ontario

Shorelines are desirable places to live, work, and play, but are also subject to flooding, erosion, and the movement of dynamic beaches. Such hazards can result in damage to property and the natural environment, social disruption, personal injuries, and loss of life. Increasing shoreline development has led to the need for public policies and regulations that effectively minimize the negative impacts of natural hazards. The paper outlines the experience of the co-authors in planning for natural hazards along the shoreline of Lake Ontario and the St. Lawrence River in Southeastern Ontario. Four case studies are reviewed to illustrate the diversity and complexity in the work. The authors suggest that sound engineering practices and clear communication with landowners about hazards can foster appropriate development. The paper concludes with six best practices for engineering and policy in managing shoreline hazards.
