Basement Flooding Study Area 57 (South Scarborough – Highland Creek East)

Basement Flooding Study Area 57 has experienced basement and recurring surface flooding during past extreme storm events. The study area is located in the West Hill and Guildwood Parkway area.

The study will determine the contributing factors for surface and basement flooding 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
  • upsizing storm and sanitary sewers in the area of Morningside Avenue and Danzig Street and;
  • upgrading the existing storm sewer outfall to Deekshill Park.

For more information on the recommended sewer improvements for the area, please view the Public Consultation tab below.

Study Area 57 map in South Scarborough - Highland Creek East.
Roughly bordered by Lake Ontario, Lawrence Avenue East, from Highland Creek to West Highland Creek.

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 public will have an opportunity to provide feedback on the study recommendations. Contact us to sign-up for updates on this study.
