The rain garden at Credit Valley Conservation’s Terra Cotta Conservation Area is a demonstration of a rain garden that is small, simple and can be implemented onto any residential property. This innovative garden collects roof runoff and uses native plants and compost-amended soil to filter out pollutants so cleaner water flows into our waterways.

Rain Garden (bioretention)
An innovative garden with compost-amended soil and native plants collects roof runoff and filters out pollutants so cleaner water flows into our waterways.

Monitoring Goals

  • Evaluating the movement of water of the LID practices 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 practice as designed before taking ownership and paying. This includes post-construction surveys, soil testing, plant surveys, and post-construction inspections.

Monitoring Progress

  • Landscaping – The rain garden is lush, but CVC is seeking consult on how-to achieve a more clean, colourful aesthetic.
  • Maintenance – CVC performs maintenance on a biweekly basis.
  • Water Levels – The rain garden is functioning as designed.
