IMAX Parking Lot Innovation

General, Low Impact Development, Water Resources

Tags: , , ,

CVC started construction earlier this month on another low impact development project, this time at IMAX headquarters in Mississauga.

The renovated parking lot at IMAX will incorporate many innovative stormwater management technologies to collect and filter out pollutants from stormwater runoff before it flows into Sheridan Creek.  This means cleaner water eventually flowing to Lake Ontario, the source of drinking water for 8 million people. These technologies will also lessen runoff entering the municipal storm system to help reduce overload and flooding during extreme weather events.

The most significant technologies at the IMAX site include:

  • Bioswales as landscaped grass or floral rain gardens that absorb and release rain water slowly, filtering out pollutants.
  • Industrial water filters that remove pollutants and slowly release rain water before it travels to the municipal storm system on its way to Sheridan Creek.
  • Permeable pavers which are specially-designed paver stones with spacing bars that create gaps for water to infiltrate into engineered soil.  Permeable paving systems allow rainwater to drain away from the surface, preventing it from rushing into municipal storm systems and extending the life of the pavement by eliminating potholes and other deterioration.

The pictures below show steps in construction from October 26th through Nov 12th. If you would like to see more, follow us on twitter, or like us on facebook. If you would like more information on this site, or any of our other projects, please visit www.creditvalleyca.ca/SWI
