Be prepared for flooding

Flooding can happen any time in Calgary. Between May 15 and July 15 is when we likely to experience flooding. Historically this is when we receive our largest rainfalls.

Our priority when responding to flooding is public safety and the protection of critical infrastructure, vital community services, the environment and the economy.

Find out what we do each year to prepare for flood season. You can also view our long-term flood resilience plan.

Please note: We do not protect individual private property from flood risk. Property owners remain responsible for protecting their property.

COVID-19 Update

To help limit the spread of COVID-19, we have included physical distancing considerations in our flood preparations. This includes:

  • Taking COVID-19 considerations for evacuees should these supports be needed.
  • Training extra staff so all critical positions have back-ups and additional support if needed.
  • Planning for how crews and support services will maintain physical distancing during an emergency response.

While we can’t prevent flooding entirely, the best way to ease the added stress amid the COVID-19 pandemic is by taking simple steps now to be flood ready.

Flood preparation for homeowners

Reduce flood damage to your home and belongings

  • Move valuables and documents out of your basement. If you need help:
  • Check your downspouts, sump and backflow preventer valve as part of your regular home maintenance schedule.
    • Direct downspouts away from home and your neighbour’s home.
    • Have a sump pump and a back-up battery power source in case you lose power.
    • Install a backflow preventer valve on your sewer pipes to prevent back-up in your basement.
  • Ask your insurer about flood insurance and review coverage in the event you need to evacuate.
  • If you’re finishing your basement use easy to clean materials in the event you are flooded with river water, groundwater or sewage.
  • Find out about sandbags or other temporary barriers.

Prepare your family in case you need to leave your home quickly

As part of your personal flood preparations during this COVID-19 pandemic, we are encouraging Calgarians to review their emergency plans.

See how to make an emergency plan.

If your family is apart, where is a place outside your community you could meet? With many facilities closed to the public or have limited access, consider meeting in an outdoor open area:

  • Large parking lots
  • Quiet streets
  • Uncrowded greenspaces

Alternative accommodations

Review where you would stay if you were instructed to leave your home. When making plans, here are some things to keep in mind.

If you/your family are healthy:

  • Talk to your friends or family ahead of time to confirm they are okay with you joining their household.
  • Discuss how you will continue to practice physical distancing and other hygiene practices to prevent the spread of the virus.

If anyone in your family or the destination household is in self-isolation:

  • Consider staying in a hotel or accommodation that is not shared.
  • If you need to stay with others, ensure the person(s) in self-isolation will have a separate room, and ideally a separate bathroom.

If you need help to evacuate or need to help a friend, family member or neighbour, take care to prevent the spread of the virus. Follow our physical distancing guidelines.

If you need to evacuate you should follow the routes provided by officials to avoid blocked or dangerous areas. If you have time, leave a note informing others when you left and where you went.

Preparing an evacuation plan and emergency accommodation will help reduce the burden on emergency response resources. If you don’t have somewhere to stay, however, The City will be able to direct you to an emergency shelter that takes the COVID-19​ situation into account.​


Create an emergency kit

Create a kit that’s ready to go. This should include essentials like prescriptions, medications, items for your pets and children, cell phone charges and personal documents.

Find the best practices for what to put in your emergency kit.

To help limit the spread of COVID-19, consider these items in your emergency kit:

  • Hand sanitizer
  • Soap
  • Cloth face coverings
