Basement Flooding Study Area 65 – Finch Avenue (Allen Road/Dufferin Street to Keele Street)

Basement Flooding Study Area 65 has experienced basement and recurring surface flooding during past extreme storm events. The study area is located in the Finch Avenue West, Allen Road/Dufferin Street and Keele Street 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 Finch Avenue West and Dufferin Street/Keele Street areas.

For more information on the recommended sewer improvements, please view the Public Consultation tab 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 include:
    • Upsized sewers
    • Underground storage sewers
    • Catch basin management

The public had an opportunity to provide feedback on the study recommendations.
