James Snow Parkway – Watercourse

  • WSP provided detailed design and construction supervision for realignment of the Mansewood Tributary to accommodate the extension of James Snow Parkway near Steeles Avenue.
  • Design incorporated bioengineering to stabilize the channel and provide increased flood storage volumes under regional flood conditions.
  • Channel was designed with a pool-run morphology, utilizing on-site materials during construction.
  • Realignment was based on natural channel design principles, and wetland scrapes were incorporated into the floodplain design to provide habitat diversity.
