The subject project included for the construction of a fire station located at the south west corner of Murray Ross Parkway at Keele Street in the City of Toronto. The proposed development included for the construction of the fire station building with associated paved access and parking and landscaped areas.
MGM Consulting provided the project architects with the preliminary and detailed design of storm, sanitary and water servicing for the site, site grading design and stormwater management design as required to achieve the Wet Weather Flow Management objectives as established by the City of Toronto.
Site grading was designed to the specific requirements as required to provide both truck and pedestrian access to the site and in consideration of the ground water table and soil types to achieve the City’s water balance objectives.
The site storm servicing was integral to the SWM design as it provided opportunities for the underground storage of stormwater during major storm events. The storm servicing design also incorporated an on-site infiltration pit designed to infiltrate clean roof drainage into the ground as required to achieve water balance objectives. On-site drainage was primarily sheet flow across impervious areas directed to an on-site bio-swale which provided additional water infiltration and treatment. A package water treatment unit was also incorporated to provide additional storm water quality treatment.
