James Klassen, Roofstar Technical Advisor, says, “I think it is a good move by the city because it’s a practical way to address a practical problem—primarily related to the storm sewer infrastructure. The system is simply too undersized for the rate of growth and capacity of the city.” Klassen also points to an additional, and potentially more serious, factor: “When storm water runoff exceeds capacity there are places where it can cross over into the sanitary water drainage system and become mixed. Storm water runoff has natural outfalls like False Creek and English Bay, so if and when crossover occurs you can have contami- nated stormwater showing up where there are beaches and swimming. And then you have issues with contaminated swimming water and health hazards. The green roof bylaw will certainly help slow down that runoff so that the existing capacity can do what it’s designed for—namely to handle the rainwater more readily without the risk of crossover.” Klassen also points out that as cities expand and more buildings go up, the Over 30 Years Experience in Roofing, Sheetmetal, Waterproofing and Panel System Installations for Commercial, Industrial and Large Scale Residential Projects.
