Downsview Park

Located on a 300-acre former Canadian Forces Base Downsview, this $22-million project will be the country’s first urban national park.

  • The Federal government is developing Downsview Park into the first national urban park in the country and wants to base its design on sustainability principles.
  • WSP refined the Master Plan for the park and is to carry out detail design with special emphasis on storm water management, including a central lake and two upstream ponds that are designed to pre-treat runoff discharging to the lake.
  • WSP also designed bioswales to provide opportunities for on-site retention of runoff.
  • The establishment of the Canada forest, a major feature of the site, will contribute to maintaining the water balance at the site by retaining rainfall in its tree canopy and through increased evapotranspiration.
  • WSP conducted detailed hydrologic/hydraulic modelling to confirm that the proposed storm water management system will achieve its water balance and runoff volume and rate targets.
