This report by TRCA evaluates the performance of stormwater source control practices retrofitted into an industrial-commercial lot located in a densely-developed portion of Toronto that drains to the Malvern Branch of Highland Creek. The rainwater cistern and landscape irrigation system, [[Infiltration trench]] and three soakaway ponds. Performance parameters examined were runoff volume reduction, rainwater use/municipal water conservation, pond drainage rate and frequency and cause of overflows. Results show that the rainwater cistern/irrigation system and soakaway ponds/infiltration trench systems reduced runoff volume from their roof drainage areas by 64% and 89% respectively over the summer to fall 2015 evaluation period. Read more about these results and the subsequent recommendations for future designs and further research are provided in the report by clicking the button above.

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%.
