What you can do
Direct rainwater away from your home
Eavestroughs and extensions should drain at least 1.5 metres (5 feet) away from yours and your neighours’ home and onto a landscaped area so the water can soak into the ground.
Help us keep an eye on storm drains
During intense rainfalls, storm drains can be temporarily overwhelmed and it may take some time for water to drain. In some areas of the city, we’ve installed a device in the storm drains to manage how fast water flows into the pipes from the storm drain that helps prevent the system from becoming overwhelmed with stormwater, avoiding water backups into basements or flooding into houses, garages and businesses.
If you see water pooling around storm drains and it hasn’t drained within 90 mins, take a photo and submit it via the 311 app or online request. This will help City crews respond on a priority basis. If safety is a concern or water is entering a building, contact 311 immediately.

Did you know?
Flooding can occur even when we’re in a prolonged drought.
Although Calgary is a dry climate and we’re currently experiencing prolonged drought conditions, flooding always remains possible. With our proximity to the mountains, we can experience unpredictable swings in the weather, from heavy rains leading to floods, to many weeks of dry temperatures and little rain leading to droughts.

Flood mitigation projects
Calgary is better prepared today for flood events like the one in 2013. We’ve taken steps to reduce Calgary’s exposure to flood damage that have reduced our flood risk by 55%. Learn more about our short and long-term actions.
