Basement Flooding Study Area 56 has experienced basement and recurring surface flooding during past extreme storm events. The study area is located in Port Union Road area, south of Highway 401, Port Union Road, Rouge River and north of Lake Ontario.
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 improving catch basin management and upsizing storm and sanitary sewers in the East and Friendship Avenue areas and a storm sewer outfall upgrade (sewer discharge outlet) to Adam’s Creek to improve energy dissipation to watercourse discharge.
For more information on the recommended sewer improvements, please view the Public Consultation tab below.
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 include:
The study was carried out following the requirements for Schedule B projects under the Municipal Class Environmental Assessment (EA) process.
