→Example 5: Wychwood Subdivision in Brampton
STEP/TRCA conducted a hydrologic monitoring and modelling study of the site in 2012/13 with researchers from The Metropolitan University to assess runoff volume and peak flow reductions. Results showed that, relative to a conventional stormwater approach without LID, runoff was reduced over the study period by between 30% and 35% for the entire site, and by between 58 and 62% in the catchment with a higher density of LID practices. Peak flows were also reduced by 73 to 78%. In the Northeast catchment, 20% of rainfall harvested from the roof was stored and reused for irrigation during the summer months. This reuse volume represented 6% of total site rainfall over 8 months. A hydrologic model calibrated using monitored data showed that the stormwater management system met the design objective of providing quantity control for the post development 100 year storm.
