Flooding in Calgary

Provincial engagement open on draft flood inundation maps

Nov. 30 – Jan. 15, 2021

The Government of Alberta has released draft flood maps meant to improve public safety, support emergency management and help build safer and more resilient communities over the long term.

These maps do not show floodway/flood fringe zones relevant to development regulation, but they provide an updated assessment of areas at risk of flooding and are important tools used by The City to inform our emergency response planning and infrastructure design. New draft flood hazard maps showing floodway and flood fringe zones are expected in 2021.

These flood inundation maps have gone through several stages of review, of which The City was a part. Now, the Government of Alberta is now looking for feedback from citizens to help ensure this work is technically sound. You don’t need to be an engineer or flood expert to view or provide feedback. The Government of Alberta will carefully consider all feedback received and will revise the draft reports and flood inundation maps to address technical errors, as appropriate.

Calgary is better prepared today for flood events like the one in 2013.

Since the 2013 flood, we have taken steps to reduce Calgary’s exposure to flood damage. These actions have reduced our flood risk by about 50%.

Learn more about our short and long-term actions. See how we're also adapting our flood plans for COVID-19.

We can’t prevent flooding entirely, and it can happen quickly with little or no warning. Protecting our community and citizens from flooding is a shared responsibility – we all have a role to play.

You can ease the stress of the flood season by taking simple steps to be flood ready: know your flood risk, take action to prepare your home and family, and sign up for alerts to stay informed.
