Basement Flooding Study Area 53 has experienced basement and recurring surface flooding during past extreme storm events. The study area is located between Lake Shore Boulevard West, Marine Parade Drive, Humber Bay Park Road West and Canadian National rail line.

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 upsizing the storm sewer under Lake Shore Boulevard West from Burlington Street to Mimico Creek and moving the sewer outfall to help to manage stormwater run-off.

The study area is located between Lake Shore Boulevard West, Marine Parade Drive, Humber Bay Park Road West and Canadian National Rail line.

  • 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.
  • Potential solutions to address flooding may include:
    • Upsize sewers
    • Underground storage
    • New or upgrade pumping stations
    • Wet/dry ponds, where space allows
