"Co-creating the St. George Rainway" was a two-year public engagement process to envision how a buried stream in Vancouver could be re-imagined on the surface of a four-block neighbourhood street using green infrastructure. City staff worked with the community and stakeholders to develop a Rainway design focused on four values: community, mobility, learning and nature. Several innovative and creative approaches were used to help meet the city's goals of engaging collaboratively with consideration towards equity, reconciliation, diversity and reciprocity. Co-creation workshops, youth engagement packages, a pop-up Rainway demonstration, citizen science biodiversity monitoring, honourariums and native seed giveaways are a few examples. The end result is a co-created design concept that innovates how a street space can be shared for rainwater management, community use and urban nature.
