Implementation Schedule and Documents
Project Implementation Schedule
An implementation strategy was adopted in October 2011 that defined phases of design and construction projects throughout the community based on flood risk priorities. West Thornhill Flood Control is a consistent with principles of Markham’s asset management plan for stormwater infrastructure, including meeting desired level of service related to flood risk mitigation.
