Groundbreakers: Getting ready for rain in Castlegreen Co-operative

June 2018: The Groundbreakers Project is now complete.  To view our 3-minute video, visit our YouTube channel. 
EcoSuperior wishes to thank all of the volunteers, partners, sponsors and supporters in this project for a successful year. As a result, three rain gardens were installed servicing six apartment units in Castlegreen Co-operative, collectively diverting up to 28 cubic metres of runoff annually. Ten rain barrels will be installed in the 500s apartment complex in Spring 2018.

EcoSuperior and Castlegreen Co-operative are breaking ground with a neighbourhood project to help reduce the impacts of urban flooding and protect local water bodies using principles of low-impact design.

The Groundbreakers Project will demonstrate how communities can create naturalized green spaces to divert water from municipal sewer systems and allow it to filter into the soil before entering McVicar Creek. Our goal is to keep local streams and water bodies cleaner and the neighbourhood more resilient during heavy rains.


How does it work? 

With the help of designers, community contributions, partnerships and volunteers, the project includes six low-impact development features, such as rain gardens, to be installed in residential areas and green spaces of the Castlegreen neighbourhood in 2017.

The Groundbreakers Project complements the broader initiatives of the City of Thunder Bay's stormwater management plan and the McVicar Creek Protection and Rehabilitation Plan. Two municipal low-impact development sites further downstream along McVicar Creek are also included in the project.

This initiative is one of three projects supported by national organization Green Communities Canada and funded by the Ontario Trillium Foundation.
