Basement Flooding Study Area 42 (Queen Street to Dundas Street, Keele Street to Don Valley Parkway)

Take the online Basement Flooding Study survey for Area 42 (Queen to Dundas, Keele to DVP)

During heavy rain, sewers can become overloaded. This increase puts pressure on the sewer systems and overland drainage routes, such as roads, local rivers and streams, which can lead to basement flooding.

In 2013, City Council approved plans to develop comprehensive plans in 67 areas across the City to reduce the risk of flooding. The City is now launching a study in area 42 and 44 to determine the factors that contribute to surface and basement flooding and recommend solutions to help reduce the risks.

A study is underway to determine the contributing factors for surface and basement flooding in the City and recommend solutions to improve the City’s sewer system and overland drainage routes in order to mitigate flooding problems.

Potential solutions may include:

♦ Upsized sewer
♦ Underground storage
♦ New pumping stations
♦ Wet/dry ponds where space allows

Study Area 42 consists of the Lower Level Combined Sewer Interceptor distributed in portions of Wards 4, 9, 10 and 13. The sewershed is roughly located in the area bounded by Keele-Dundas-Queen Streets & Don Valley Parkway and Lake Ontario.

The City also has a subsidy of $3,400 Basement Flooding Protection Program (BFPP) for homeowners who install flood protection devices.  More information at:
