Unitarian Church is located in south-east Mississauga and has installed a rain garden in the middle of their parking lot to collect stormwater runoff. Sheet-flow from the parking lot will drain directly into the rain garden that is bordered by a grass swale.

Innovative Clean Water Technologies

Rain Garden (bioretention)
An innovative garden with engineered soil, a grass swale border and a variety of native and ornamental plants collect parking lot urban runoff and filter out pollutants so cleaner water flows into storm sewers and eventually into Lake Ontario.

Monitoring Goals

  • Evaluating the movement of water of the rain garden through the use of rainfall data in combination with water level loggers or outlet flow loggers.
  • Quantifying establishment and ongoing maintenance requirements for the rain garden with varying design features and drainage areas (area that rainfall drains into system).
  • Evaluating the success of plant species used within the practice based on health, maintenance and urban aesthetic standards.
  • Testing and developing protocols to ensure the contractor has properly constructed the innovative landscaped stormwater practices as designed before taking ownership and paying. This includes post-construction surveys, soil testing, plant surveys, and post-construction inspections.

Monitoring Progress

  • Landscaping – The landscaping consists of a grass swale border around the edge of the rain garden and a variety of native and ornamental plants.
  • Maintenance – Church volunteers have been performing maintenance including litter pickup, watering and weeding.
  • Water Levels – Initial results show that the rain garden is functioning as designed during smaller rain events.
