Stormwater Management in Oakville – Dodging the Extreme Rainfall Bullet


The Town of Oakville has been considering climate change within the context of environmental policy for about ten years. Most recently, between 2011 and 2014 the town developed a comprehensive Climate Change Strategy approved by Town Council in September 2014. A key vulnerability for the town exists in the potential for climate change impacts on the stormwater management system. Stormwater management practices have evolved over the past few decades and as such various levels of best management practices exist across the town. There are various mechanisms contributing to flooding concerns and jurisdiction varies for each. Riverine flooding concerns are shared with the Conservation Authority that regulate the creek floodplains. The minor and major storm drainage systems are the responsibility of the town. Flooding related to surcharging sanitary sewers is the responsibility of the Region of Halton.

Through the completion of a town-wide Flood Study in 2008, staff has a good understanding of riverine flooding issues. The same level of understanding is required with respect to flooding issues related to the town’s minor and major drainage systems. There are areas within the town that would be vulnerable to flooding during extreme rainfall events due in part to the nature of the stormwater management practices considered at the time of development. There is a broad range of flooding issues and concerns across town including the following: nuisance drainage issues; flat ditches that are increasingly stressed, lack of defined major overland system, and historic remnant drainage channels in backyards that have been compromised over time.

In recent years, several neighboring municipalities have experienced significant drainage issues in response to very intense rainfall events. Stemming from these recent extreme local rain events, the town is undertaking its first Stormwater Master Plan. Town Council and Senior Management have recognized the importance of developing and implementing coordinated capital programs to address the town’s infrastructure needs.
