The City of Vancouver takes environmental stewardship seriously, and has an action plan to become the “Greenest City in the World” by 2020. Smart redevelopment fits within that plan. Vancouver’s Chinatown, located between Gastown and the downtown Financial and Central Business Districts, is undergoing a revitalization that will preserve its history and cultural identity,while implementing some of the latest in clean technology. One example is a Main Street site that has been redeveloped by Bosa Properties to erect anew 18-story 192-unit luxury apartment building with commercial retail on the ground floor.

In an effort to reduce the environmental impact of Vancouver’s building sand nurture a growing green building movement, the City Council requires all new buildings on rezoned sites to be built to the LEED Gold standard, with a minimum of 1 water efficiency point and 1 stormwater point included. 

LEED credit was obtained within this development by implementing the performance verified Jellyfish Filter JF4-2-1 within the building envelope, supplied under license by the Langley Concrete Group. A small, 48-inch diameter Jellyfish Filter treats runoff from roughly 0.15 ha of impervious drainage with three lightweight filter cartridges that are easy to rinse and reuse. The compact Jellyfish was installed in the lower P1 level, consuming very little space within the parking garage while maximizing the developable land and its value.

“The Jellyfish unit worked really well with our project as it was a perfect fit for this inner city development. The footprint and design could accommodate a tight spot within the parking garage P1 level. Consideration was given to a gravity device, but considering the City’s LEED stormwater requirement we chose the Jellyfish Filter,” said Dave Wood, Senior Designer at the Integral Group. “The cooperation and design assistance with Imbrium and Langley Concrete Group went very well.”

The overall site design and layout with the Jellyfish was forward thinking, accounting for periodic inspections, and annual maintenance. The unit is accessible at street level, so the system can be inspected, cartridges rinsed and reused, and pollutants removed with ease by a vacuum truck at an overall lower cost-in-use compared to other stormwater filtration systems.
