The City of Vancouver, British Columbia, has been separating sewers since the 1970s to reduce combined sewer overflows and comply with its Liquid Waste Management Plan. Looking ahead, the City and its partners recently launched the Healthy Waters Plan (HWP) to address population growth, climate change impacts, and improve stormwater quality using green and grey infrastructure. Session participants will learn about Vancouver’s innovative engagement and planning process to integrate community values, technical data and structured decision-making to shape future investments. The approach and learnings are applicable to help address stormwater challenges and opportunities faced by cities across the U.S. The project aligned different perspectives and gained agreement on a pathway forward that optimizes infrastructure investments to reduce overflows and flooding and improve stormwater quality while addressing climate-related changes, population growth and reconciliation with First Nations. This case study session will share technical findings and the innovative engagement processes used in this plan that other stormwater leaders and U.S. communities can consider.
