Sherbourne CommonToronto, Ontario, Canada
- The 3.6 acre, $30 million project is a novel hybrid: it’s both a park and a stormwater treatment plant that reduces stormwater runoff and combined sewer overflows (CSOs) into Toronto’s Lake Ontario.
- The park was transformed from a brownfield into one of the Toronto waterfront’s main green space in 2011.
- Sherbourne Common’s stormwater treatment uses Ultraviolet (UV) technology instead of chlorine to treat the water. After UV treatment the water flows through a 240-meter long urban river, a bio-filtration bed, and is then released into Lake Ontario.
- Sherbourne Common is the first park in Canada to receive LEED gold certification.
- The park contains about 182 native or regionally adapted trees: 108 Pacific Sunset Maple, 45 Red Oak, and 29 American Beech.
- The park incorporates locally-available materials, extensively uses light-colored permeable paving surfaces to reduce the urban heat island effect, and uses special light fixtures to reduce light pollution.
