Almost four years after the Calgary flood of 2013, flood-damaged areas have been rebuilt and efforts are underway to protect the city with new flood mitigation measures.

In riverside communities, such as Sunnyside, which was mostly saved from the raging Bow River by a berm constructed in the 1930s, obvious signs of flooding are mostly gone, but memories still linger.

"There are some people – you can see it in them – when spring melt starts to come, you can see them get anxious, (wondering) what is going to happen?" said Charlie Lund, chair of the Infrastructure Group, with Hillhurst Sunnyside Community Association's Emergency Preparedness and Response Committee.
