Analyzing the Implication of Blue Green Solution in the Toronto Area

Increased precipitation intensity and frequency associated with climate change were observed in a lot of studies. In the case of poor stormwater management, it is more likely for flooding to happen with extreme weather. As a city facing challenges related to flooding, the city of Toronto needs to have an efficient stormwater management system. This study, therefore, explores the Blue Green Solution (BGS) and its feasibility in Toronto. Suggestions were proposed according to common barriers identified for green infrastructure development at different stakeholder levels. This study suggests BGS would have better effects on stormwater management compared to Low Impact Development. Governments are advertised to take a leadership role in raising funds, providing political guidance and promoting stakeholders to be involved in BGS development. Modelling and monitoring as a highlight of BGS, should be performed when designing a project. Involvement of all stakeholders seems to be one of the solutions to ensure interactive and integrative BGS design which allows better performance of urban stormwater management.
