NOTE: TRCA utilizes the best technology and latest available data in preparing floodplain mapping. As modelling techniques continue to evolve and as new information continues to be gathered, the resulting updated floodplain mapping products can change the risk and damage calculations, as well as the ranking of TRCA’s flood vulnerable clusters in the future. Map data generated December 2018.

Disclaimer: The data used to create this map was compiled from a variety of sources and dates. TRCA takes no responsibility for errors or omissions in the data and retains the right to make changes and corrections at any time without notice.

Understanding Flood Risk in Spring Creek


KNOW THESE TERMS:

Flood Vulnerable Cluster: An area within the floodplain with a high concentration of buildings and roads that could be impacted by riverine flooding.

Special Policy Area (SPA): An area within a community that has historically existed in the floodplain and where site-specific Provincial policies are intended to provide for the continued viability of existing uses.


The Spring Creek cluster is subject to flooding because the stream is not fully able to carry all flows through the openings of multiple culvert crossings. Constrained channels (on both Spring Creek and Dixie tributary) also contribute to the problem.

This cluster could receive significant spills from the river, particularly through the Peel Centre Drive area and the Avondale Special Policy Area, or SPA (see SPA definition above).

The known flood locations are:

  • Bramalea City Centre is subject to flooding because the exiting culverts and watercourse don’t have adequate conveyance capacity. The culvert under Clark Boulevard creates significant backwater* upstream, which also contributes to flooding in the area.

*NOTE: Backwater is the term for water that has been backed up in its course by some form of obstruction.

  • Birchbank Public School. Flooding in this area typically occurs when flow exceeds culvert capacity and becomes backed up — in particular, at the culvert under the Birchbank P.S. entrance road.
  • Flooding may occur upstream of Central Park Drive (Spring Creek). A restricted culvert in this area can lead to backwater* upstream of the Central Park Drive and Hilldale Crescent culverts.
  • There is risk of flooding in the vicinity of Chinguacousy Park due to channel capacity issues and the storage capacity of the park’s ponds. The Queen Street culvert also causes backwater* issues.

  • The Avondale Boulevard area can be prone to flooding. The Avondale Boulevard culvert creates a backwater* effect and can cause flow to spill in the vicinity of the culvert crossing.
  • High-risk flood zones appear just north of Highway 407 along Spring Creek. Insufficient channel capacity can cause issues all the way from downstream of Alfred Kuehne Boulevard to upstream of the Highway 407 Bridge.

What Types of Flooding* Can Affect Residents?

  1. River flooding, which occurs when the water levels of rivers rise, overflowing their banks. Reducing riverine flood risk is under the mandate of Conservation Authorities like Toronto and Region Conservation Authority (TRCA).
  2. Urban or pluvial flooding consists of street flooding, basement flooding and flooding of other low-lying areas due to the overflow of local drainage systems. Municipalities are responsible for managing this type of flooding.

*Did you know that there are several types of flooding? Different levels of government are responsible for different types of flooding. To find out who to contact during a flood, see BE PREPARED.

Flooding Can Happen at Any Time of Year

winter icon WINTER: A rise in the water level or a thaw can break winter ice into large chunks, which can lead to jams due to blocked culverts in this area.
spring icon SPRING: Spring Creek can experience high flows in the early spring, as rising temperatures melt the winter’s accumulation of snow, causing water levels to rise.
summer icon SUMMER: Intense, localized downpours from thunderstorms can quickly lead to flooding in smaller locales such as Spring Creek.
fall icon FALL: Large wet weather systems, including tropical storms such as Hurricane remnants (like Hurricane Hazel in 1954), can last for several days. Prolonged and heavy precipitation, on top of already saturated soils, can cause rivers to rise.

How Will I Know If Flooding Is Forecasted?

  • TRCA Operates a Flood Forecasting and Warning Program. If flooding is possible or about to occur, TRCA issues flood messages to designated individuals within municipalities, local agencies, school boards, the media, and members of the public who self-subscribe. LEARN MORE
