Basement Flooding Study Area 53 (Lake Shore Boulevard West and Mimico Creek area)

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 CN rail line.

Based on investigations of drainage and flooding, the City has evaluated a number of alternative solutions and is recommending:

  • an upgrade to the storm sewer along Lake Shore Boulevard West, south of TTC streetcar track from Fleeceline Road to existing Mimico Creek storm sewer outfall
  • four high-capacity catch basins on Lake Shore Boulevard West along the new storm sewer and at Greystone Court
  • upsizing the existing Mimico Creek storm water outfall at Humber Bay Park.

 

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 area is located between Lake Shore Boulevard West, Marine Parade Drive, Humber Bay Park Road West and CN 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:

  • Upsized sewers
  • Underground storage
  • New or upgraded pumping stations
  • Wet or dry ponds
