Calgary Zoo Flood Mitigation

by | Sep 18, 2017

The Calgary Zoo Flood Mitigation project consisted of the installation of a steel sheet pile cofferdam wall around the perimeter of St. George’s Island, designed to protect the Zoo’s infrastructure from rising waters experienced during flooding of the Bow River. It features two kilometers of sheet pile driving into bedrock, eight dewatering wells with four outfall structures to the river, multiple utility relocations, and construction of new roadworks and pathways done by ALSA, including drainage improvements. Architectural finishing details include rock infills, concrete coping, landscaping, and fencing.
