For over a decade, Green Calgary has been developing urban stormwater-management solutions through rainwater-harvesting initiatives. After the 2013 floods, they embarked on a more focused and systematic approach to helping Calgary better prepare for extreme-weather events, the effects of which may be mitigated by green stormwater management practices. In 2014, through a national study with the University of Waterloo, Green Calgary gathered information from homeowners to better understand their impact on stormwater management on private property. At the same time, in partnership with Green Communities Canada, they launched Depave Calgary to implement projects that remove unnecessary pavement and replace it with green spaces to increase the permeability of urban surface areas. Working with various community groups and volunteers, Green Calgary is innovating how we understand, plan and react to extreme weather events resulting from climate change in our cities.
