Basement Flooding Study Area 58 has experienced basement and recurring surface flooding during past extreme storm events. The study area is located in the Don Rivershed, from Steeles Avenue and Keele Street to Victoria Park Avenue and Eglinton Avenue area.

The study will determine the contributing factors for surface and basement flooding in the area and recommend solutions to improve the City’s sewer system and overland drainage routes in order to mitigate flooding problems.

Based on investigations of drainage and flooding, the City has evaluated a number of alternative solutions and is recommending improving catch basin management and upsizing storm and sanitary sewers in the Robert Hicks – Finch Avenue and Bathurst Street; Yonge Street and York Mills Road, Wilson Avenue and Avenue Road, and Eglinton Avenue and Don Mills Road areas.

 

For more information on the recommended sewer drainage improvements for the study area, please see the Public Consultation Section below.

  • During heavy rain, sewers can become overloaded with stormwater runoff. This puts pressure on the City’s sewer systems and overland drainage routes, such as roads, local rivers and streams, which can lead to basement flooding.
  • Recommended solutions to address flooding included:
    • Upsize sewers
    • Underground storage sewers
    • Catch Basin management

The City of Toronto is studying ways to help reduce future surface and basement flooding in your area. Through our investigations of drainage and flooding, the City has evaluated a number of alternative solutions and is recommending upsizing the the storm sewer outfall into the creek to manage stormwater quantity.
