The Lakeview Green Street project is leading the way in protecting our water by using enhanced roadside rain gardens and permeable paver driveways to reduce stormwater runoff and improve water quality flowing into storm sewers and eventually into Lake Ontario within the  Lakeview Neighbourhood in Mississauga. This project is the “first of it’s kind” in Canada and will replace traditional curb, gutter and buried sewer systems.

 

Innovative Clean Water Technologies

As  an alternative to traditional asphalt, permeable driveways will replace the portion of the driveway that is city owned. Permeable pavement is a specially-designed paver stone, with spacing bars that create gaps or joints between the units, laid on top of engineered soil. Permeable paving systems allows rainfall and road runoff to be filtered as it flows through the pavers and returns to the ground.

Rain gardens will be installed along residential streets and will help reduce stormwater runoff and improve water quality flowing into storm sewers and eventually into Lake Ontario. Rain gardens or bioretention is cost effective, preferred by residents, and better for the environment.

Street runoff enters the bioswales through curb cuts for treatment to reduce stormwater flows.

 

 

 

Project Schedule

Construction

  • Construction start date: July 2010
  • Construction end date: August 2012

Monitoring

  • Pre-construction monitoring began in July 2010 and was completed in April 2012
  • Flow and water quality monitoring at a control site have been ongoing since July 2010
  • Flow and water quality monitoring at a site with traditional swales took place from July 2010 until April 2012 when the site was removed for construction. This monitoring station was re-established in August 2012 once construction ended.
  • Flow monitoring at two LID sites has begun in August 2012. Water quality monitoring also started at one of these sites in August 2012
  • The aim of sample collection is to collect samples from 20 wet weather events in the post construction phase per monitoring location before December 20, 2013.

Monitoring Goals

Monitoring objectives for Lakeview include:

  • Evaluate the performance of LID practices in reducing runoff volume, peak flows, pollutants, erosion, and restoring the natural water balance
  • Compare runoff volume reduction and the quality of runoff between areas with LID infrastructure, traditional swales and standard curb and gutter
  • Help determine maintenance requirements for optimal LID performance
  • Evaluate the degree to which LID reduces the impacts of extreme weather events due to climate change and builds resiliency in municipal infrastructure
  • Meet the objectives of CVC’s monitoring strategy report (available at www.bealeader.ca

Monitoring Progress

Since August 2012, for rain events up to 27mm, no outflows were observed at either of the two LID monitoring stations. In other words, roughly 95% of all rainfall events are being filtered and cleaned before entering Lake Ontario.
