Storm Water Management

Revised Unionville Flood Plain & Special Policy Areas

In 2019 the Toronto and Region Conservation Authority (TRCA) revised the flood mapping in and around Unionville, using advanced LIDAR technology. At the confluence of Bruce Creek and the Rouge River, much of Unionville has always lain within the flood plain. Most of the village flooded during Hurricane Hazel in 1954. The City is also redrawing the Special Policy Areas within the flood prone zones.

The revised policies are designed to keep people safe in the event of a flood, such as the 2013 floods in Calgary and High River, Alberta that seriously damaged residential neighbourhoods built in flood plains.

Reid made sure that the community was well aware of the impact of redrawn flood lines and Special Policy Areas. This will have an impact on development rights and property insurance rates and availability for some residents.

The Federal Government is considering a program to offer overland flood insurance to homeowners in identified flood plains. Reid will work with our federal MP to advocate for this new policy to help protect Unionville residents.

Preparing for the Next Big One!

Storm Sewer Upgrades in Unionville

In 2005 an intense localized rain storm flooded large sections of Thornhill in Markham. This revealed the inadequate storm water management system there. Subsequent studies have revealed similar risks in parts of Unionville and Markham Village.

Massive remediation work has been undertaken in Thornhill to upgrade the storm sewer system. Similar works will begin in parts of Unionville in 2028. Public consultation began in 2021 and Reid will continue to keep affected residents in the loop as the project approaches. 2028 may seem a long time in the future, but it will be here sooner than we think.
