In partnership with The City of Barrie we implemented low impact development at the Victoria Woods parking lot. The previously impervious, hard-packed gravel has now been resurfaced and runoff is redirected from the new asphalt surface into a bioretention swale.
The bioretention swale will filter up to 42 cubic metres of stormwater during a major storm event, while also reducing phosphorus by 0.5 kilograms per year.
What is a bioretention swale?
Bioretention is a low impact development technique that provides storage, treatment, infiltration and routing of surface water runoff in a landscaped area. Bioretention features mimic natural processes by absorbing water and filtering pollutants, directing water back into the ground or overland to appropriate outlets.
