Flood mitigation and resilience projects

Since the 2013 flood, we have committed over $150 million for various flood mitigation and resilience projects throughout Calgary.

To date we have completed 11 of the Expert Management Panel recommendations, and the remaining 16 are currently in progress. Mitigation work that is already complete or is underway has reduced Calgary's exposure to flood damage by about 30 per cent compared to 2013.

In 2016, The City of Calgary undertook a Flood Mitigation Measures Assessment to develop recommendations regarding the future of Calgary's flood mitigation and resiliency.

These recommendations were unanimously accepted by City Council on April 10th, 2017, and flood mitigation and resilience for Calgary has been identified as one of Council's top priorities.
