CALGARY ZOO FLOOD MITIGATION
Location: Calgary, AB
Project Type: Municipal Infrastructure
About This Project
With St. George’s Island located at the confluence of the Bow and Elbow Rivers, the Calgary Zoo has been subject to many flood events throughout its history. Along with much of Southern Alberta, record flooding occurred on the Bow and Elbow Rivers in June 2013. The Calgary Zoo was inundated and without power in the early morning hours of June 21, having had less than 10 hours’ notice to enact their flood operations plan. In that time, without a single loss or incident, the Zoo evacuated as many animals as possible from the collection of more than 200 animals on the island. As the floodwaters receded, the cleanup began in the days and months that followed and questions arose about the future viability of the Zoo’s island home.


It was a testament of Cal McClary’s project leadership that, when he unexpectedly passed in November 2016, the rest of the team were able to overcome extraordinary circumstances while continuing to execute his vision through the final construction and commissioning phases. The project was dedicated in Cal’s honour recognizing his critical role in preserving and protecting the Calgary Zoo on St. George’s Island. As one of the city’s most iconic landmarks with nearly a century of history, the Calgary Zoo will remain in its founding location, operating a world class facility as Canada’s leader in wildlife conservation and a destination for global tourism for the enjoyment of future generations.

Making Cal Proud
Whether it’s an organization or a project, for me its “all about people” and that philosophy leads to these type of successes and this project was very successful! I am also happy to say that I believe Cal would be very proud of not only what was accomplished but how itwas accomplished!
