Basement Flooding Study Area 59 is located in the south Scarborough area roughly bound by Sheppard Avenue to the north, Warden Avenue/Brimley Avenue/Bellamy Road to the west, Orton Park to the east and Kingston Road to the south.

This area has experienced basement and surface flooding during extreme rainfall events. A study is underway to determine the contributing factors to surface and basement flooding. The City is recommending solutions to improve the City’s sewer system and drainage routes in order to mitigate flooding problems.

During extreme rainfall events, sewers and drainage systems can become overloaded, which can lead to basement and surface flooding. In 2013, City Council approved the development of comprehensive plans across 67 study areas in the city to reduce the risk of flooding. The study for area 59 began in 2022.

City staff have studied the factors that contribute to surface and basement flooding in the area, and have developed recommended solutions to address these issues.

What is Covered by this Study

Following the Municipal Class Environment Assessment process for planning and designing municipal infrastructure, this study has recommended potential improvements to the sewer and drainage system that could be made within the City’s right-of way or City property, such as parks and ravines.

What is Not Covered by this Study

Each property owner is responsible for drainage systems on private property, including operations and maintenance. This includes:

  • Lot grading
  • Front and rear-yard or driveway drainage catchbasin
  • Foundation drains
  • Sump pumps and backwater valves
  • Private tree roots and what you put down the drain (fats, oils, grease, etc.)
  • Disconnecting downspouts

The City is recommending the following solutions to address surface and basement flooding in the area:

  • Replacement of existing storm and/or sanitary sewers to increase the size of the pipe, and allow sewers to carry greater volumes of stormwater away from streets and hard surfaces
  • Construction of new underground storage tanks to temporarily store water during storm events and relieve overloading of the sewer system
  • Increasing the number of catch basins to capture more flow from the surface
  • Replacement of storm sewers along enclosed creek sections to improve flow capacity

Where solutions are located outside of the City’s right-of-way, the City has evaluated alternative solutions for sewer system improvements.

The recommended solutions are not yet funded by the City. Further detailed engineering work must be completed to confirm project details, which may take a number of years to complete. This detailed engineering work and funding approval would be needed before any construction takes place.

Public Drop-In Event

The Public Drop-In Event was held on Wednesday, July 17, 2024 from 6 to 8 p.m. at Scarborough Village Recreation Centre, 3600 Kingston Road, Scarborough. This event provided an opportunity to view the project information panels and speak with members of the project team one-on-one.

Following consideration of public feedback on the recommended solutions, City staff will complete the final study report and issue a notice of completion. The study report will be made available for a 30-day review period from the day the Notice of Completion is issued.
