Cities across Canada are moving from grey to green infrastructure in managing rainwater. Green roof is an effective source control tool with multiple co-benefits. It offers a practical solution in tight urban spaces where other rainwater management tools are not feasible.  As such, green roofs play a key role in the City of Vancouver’s (CoV) new simplified rainwater management (RWM) requirements for new Part 3 buildings that took effect on January 1, 2024. In this webinar, we will learn how to design green roofs to help meet CoV’s retention/detention requirements and when upgrading to a blue-green roof can increase ROI.

Learning Objectives | At the end of this session, participants will:

  1. Understand CoV’s new simplified rainwater management (RWM) requirements.
  2. Use a green roof to maximize the reduction of CoV’s detention volume requirement.
  3. Design detention green roofs using modeling to help meet a site’s release rate target.
  4. Engineer green roofs with enhanced RWM abilities to achieve financial savings.
  5. Apply an interdisciplinary approach to create a multifunctional green roof.
