The emphasis to maintain pre-development hydrology and attain runoff volume target control, have made the use of Low Impact Development (LID) stormwater management practices essential. Innovative LID practices like Etobicoke Exfiltration System (EES) and Damming Baffles (herein referred as Inline Flow Restrictors (IFRs)) are used to promote exfiltration and detention of runoff, that addresses the stormwater goals of urbanized area with limited space for LID. An existing, calibrated Dual Drainage (DD) model is modified using USEPA SWMM (v5.2) to explicitly model the minor and major system flows, for study area in the Town of Richmond Hill, Ontario. The model investigates the hydrologic performance of dual drainage system with EES, and IFRs as compared to a dual drainage system with wet pond, in terms of runoff volume and peak flow reduction. Model results indicate significant runoff volume reduction and manageable maximum peak flow with respective addition of the EES and IFRs.
