Solutions to a summer of floods
Valerie Burke Thornhill Ward 1 Councillor
Thornhill experienced heavy rains exceeding the current extreme storm management infrastructure, resulting in flooding in several areas this summer. These high rain intensities greatly exceeded the capacity of the infrastructure systems.
Since the Aug. 19, 2005, storm, Markham City Council approved and implemented the West Thornhill Stormwater Flood Remediation plan, a long-term flood control strategy, to improve storm drainage capacity and limit surface and basement flooding risks in urban areas.
The West Thornhill Stormwater Flood Remediation plan sets out improvements based on dealing with the most severe flood risks first. Further system upgrades are still planned as part of the long-term flood risk reduction strategy. However, some areas in West Thornhill have not yet received the benefit of these improvement works.
Residents and businesses are encouraged to help reduce the risk of flood damages on their property by keeping rain gutters and catch basins free of debris, disconnecting and positioning downspouts away from foundations and reducing pavement and other impermeable surfaces. Planting trees and shrubs helps mitigate storm water naturally. Cooking oils should always be disposed of in the green bin, not down the sink or in the street catch basin.
Furthermore, it is important that residents advise the city of flood incidents, so staff can continue to refine flood remediation design.
