As part of the Ottawa River Action Plan (ORAP), the City of Ottawa implemented stormwater retrofit measures to reduce and treat runoff from existing urban areas. The general concept for Stewart Street was presented at public open house for the East-West Bikeway (which Stewart Street is part of) on October 18, 2012.  The changes involved shifting the curbs, painting a westbound cycle lane on Stewart from Nelson to King Edward and opening the curbs to allow storm water run-off into the boulevard rather than into storm sewers.
