This report by TRCA highlights the multiple LID installations located at Edwards Gardens, a botanical garden located at 777 Lawrence Avenue East in Toronto, Ontario and owned by the city. The retrofit of the Edwards Gardens parking lot introduces several new technologies to add to the existing Low Impact Development (LID) practices onsite – an extensive [[Green roof]] and a [[Rainwater harvesting]] system, along with [[Bioretention]], [[Permeable pavement]], [[Infiltration trenches]], [[Exfiltration trenches]], and [[Swales]]. The stormwater management benefits of the LID practices implemented onsite help to improve the quality and reduce the volume of runoff discharging to Wilket Creek, nearby.

This technical brief discusses TRCA's study that evaluated the effectiveness of meeting provincial and municipal stormwater management and flood control criteria on a commercial property by using a combination of decentralized LID practices as an alternative to sole reliance on centralized stormwater detention facilities. Practices incorporated into the design included [[Bioretention]], [[Permeable pavements]], [[Swales]] and [[Rainwater harvesting]] and re-use for landscape irrigation. Results from the study period found that, relative to a conventional stormwater approach without LID, runoff was reduced by 30-35% for the entire site, and by 58-62% in the catchment with a higher density of LID practices, peak flows were also reduced by 65 to 79%.
