This workshop will begin with an introduction to GI and the drivers for implementing it in Vancouver. Then the City of Vancouver GI design team will delve into the detailed design of a bioretention system using a City of Vancouver case study project. The session will cover geotechnical requirements, sizing methodology, recommended design details, and the importance of soil specifications and planting design to project success. Finally, an overview of other GI tools, such as green roofs and rainwater harvesting, and considerations for how they are implemented in a Vancouver context will be presented.
