The Ultimate Flood Preparedness Guide: How to Stay Safe Before, During, and After a Flood

Floods are among the most frequent and destructive natural disasters in Canada, affecting communities nationwide with devastating consequences. A flood occurs when water overflows onto normally dry land, ranging from a few inches of standing water to catastrophic levels that submerge vehicles and buildings. Floods can happen at any time of year and result from various factors, including heavy rainfall, rapid snowmelt, storm surges, and dam failures. No region in Canada is entirely safe from flooding. From the coastal areas of British Columbia to the plains of Alberta and urban centers like Toronto and Montreal, floods are influenced by local geography and weather patterns. Urban flooding often results from excessive rainfall overwhelming drainage systems, while river floods occur due to prolonged rainfall or rapid snowmelt.

History has shown the destructive power of floods in Canada. The Saguenay Flood of 1996 in Quebec caused over $1.5 billion in damages, forced 12,000 people to evacuate, and tragically claimed 10 lives. More recently, Alberta and British Columbia have endured severe flooding, with BC experiencing water levels not seen in 100 to 200 years. In Fort McMurray, over 13,000 residents were forced to evacuate due to rising waters.

Understanding floods and knowing how to prepare, respond, and recover are essential for reducing their impact on lives and property. This guide will walk you through the critical steps to take before, during, and after a flood to improve your flood preparedness and keep yourself, your family, and your community safe.

Steps to Take Before a Flood: How to Prepare and Protect Your Home

Flood preparedness starts long before water levels begin to rise. Taking proactive measures can significantly reduce flood damage and make the recovery process easier. Below are key steps you can take to protect your home and family from flooding.

Securing Your Home Against Flood Damage

A flood-resistant home is your best defense against rising waters. Implementing the following precautions can help minimize structural damage and water intrusion:

• Apply Weather-Proof Sealant - Use a weather-protectant sealant around basement windows and the base of all ground-level doors to prevent water from seeping into your home.
• Consider Flooring Alternatives - Replace carpets with materials that are easier to clean and less susceptible to water damage, such as tile or vinyl flooring.
• Install Downspouts and Gutters - Ensure water drains properly away from your building by installing downspouts and gutters that direct water at least three feet away from the foundation.
• Check Local Flood Plans - Contact local authorities to understand flood risks in your area, including floodplain maps, flood plans, and potential relocation routes.
• Install a Sump Pump - A sump pump can help keep your basement dry during a flood. Also, consider installing zero reverse flow valves in basement floor drains to prevent sewage backup.
• Prepare a Flood Emergency Kit - Create a portable emergency kit. This kit should include essential items like water, food, medications, and important documents. Ensure it is easily accessible.

• Store Important Documents Safely - Keep critical documents such as insurance policies, identification, and financial records in a waterproof container.
• Obtain Flood Insurance - Standard home insurance policies often do not cover flood damage, so talk to your insurance company and ensure you have appropriate coverage. Take pictures or videos of your belongings. This provides a record for the insurance company and can help speed up claims.
• Elevate Valuable Items - Store important belongings and valuables above typical flood levels to protect them from water damage.

What to Do When a Flood Is Imminent: Essential Safety Steps

When a flood warning is issued or severe flooding is imminent, taking immediate action can help safeguard your home and protect your loved ones. Follow these critical flood preparedness steps to minimize damage and ensure your safety.

• Turn off Utilities - Shut off your basement furnace and the outside gas valve to prevent damage and reduce the risk of fire or explosion. Do not attempt to shut off the electricity if water is present.
• Safeguard Electrical Systems - Secure electrical, natural gas, or propane heating equipment by relocating it to higher ground or protecting it from water exposure.
• Move Belongings to Safety - Roll up rugs and move furniture, electrical appliances, and other valuables to an upper floor or higher ground.
• Remove Hazardous Materials - Relocate toxic substances like chemicals, cleaners, and pesticides from areas at risk of flooding to prevent water contamination.
• Plug Sewer Drains - Remove toilet bowls and plug basement sewer drains and toilet connections with wooden stoppers to prevent sewage backup.
• Disconnect Eavestroughs - If your eavestroughs are connected to the house sewer system, disconnect them to avoid water entering your home.
• Use Flood Barriers - If applicable, set up sandbags or polyethylene barriers around your property to deflect water.
• Evacuate if Necessary - Leave your house immediately if evacuation is advised and move to higher ground. Only return when authorities confirm it is safe.

What to Do During a Flood: Stay Safe in Rising Waters

During a flood, your top priority should be staying safe and avoiding hazardous conditions. Floodwaters can be unpredictable, fast-moving, and highly dangerous. Follow these critical flood preparedness steps to protect yourself and your loved ones.

• Stay Informed - Keep a battery-powered radio or other reliable information source handy to receive updates on flood conditions and evacuation orders from local authorities.
• Keep Your Emergency Kit Ready - Ensure your emergency kit is close at hand and stored in a portable container. It should be easy to grab in case you need to evacuate quickly.
• Avoid Flood Waters - Do not enter floodwaters under any circumstances. Flood waters are often contaminated with hazardous substances, including sewage and chemicals, and may hide dangerous debris or downed power lines.

Understanding Different Types of Floods to Improve Preparedness

While the general principles of flood safety apply to all situations, certain specific considerations may arise depending on the type of flooding or the environment in which it occurs:

• Urban Flood - In cities, flooding can quickly overwhelm drainage systems, leading to flash floods that can occur with little warning. Avoid driving or walking through flooded streets. Even shallow water can be dangerous. Remember that urban flooding can disrupt essential services like electricity, water, and sewage systems, so be prepared for potential outages.
• River Flood - River floods can develop more slowly than flash floods but can be just as dangerous. If you live near a river, pay close attention to flood warnings and be ready to evacuate if water levels rise rapidly. River flooding can also lead to extensive property damage due to prolonged water exposure, so taking early precautions, such as moving valuables to higher ground, is crucial.
• Coastal Flood - Coastal flooding is often caused by storm surges associated with hurricanes or other severe storms. If you live in a coastal area, be aware of evacuation routes and heed warnings from local authorities. A coastal flood can be particularly destructive, combining the effects of high winds, waves, and rising water levels. 

Returning Home After a Flood: Essential Steps for a Safe Recovery

Once the floodwaters have receded and authorities have declared it safe to return home, you begin the recovery process. This can be a challenging and emotional time, but following these steps can help ensure a safe and thorough clean-up:

• Wait for the All-Clear - Do not return home until local officials confirm it is safe. Flood damefore spending extended time inside.
• Clean and Disinfect - Floodwater can be heavily contaminated, so it’s crucial to clean and disinfect all surfaces, appliances, and systems thoroughly. Use a mixture of unscented detergent and water for cleaning.
