Green Glade Sr. Public School, Mississauga
The rain garden retrofit at the Green Glade Sr. Public School has a dual purpose: it cleans stormwater from the school rooftop and urban runoff from the parking lot and it eliminated a nuisance ponding problem in the parking lot.
Innovative Clean Water Technologies
This innovative garden collects roof runoff and uses native plants and engineered soil to filter out pollutants so cleaner water flows into our waterways.
- Evaluating the movement of water of the LID practice 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.
- Landscaping – The plants at Green Glade are in their second year of establishment and are lush in the summer.
- Maintenance – Biweekly maintenance inspections are conducted by CVC.
- Water Levels – Initial results have shown that the rain garden is working and has not experienced ponding on its surface. The rain garden has very sandy soils and is able to quickly soak up rainfall before it can pond.
