How to Prepare for a Flood
Flooding is one of the most common and devastating natural disasters in the world. Whether caused by heavy rainfall, storm surges, or overflowing rivers, floods can strike with little warning, leaving homes, businesses, and communities in crisis.
At Hope Force International, we have witnessed firsthand the destruction that floods bring—and the resilience of those who prepare. By taking proactive steps now, you can safeguard your home, protect your family, and respond effectively when the waters rise.
This guide will walk you through everything you need to know about flood preparedness, response, and recovery, helping you take action before disaster strikes.
Understanding Floods
What Is a Flood?
A flood occurs when water overflows onto land that is normally dry. Flooding can happen gradually over time or as a sudden, catastrophic event. Common causes of flooding include:
- Heavy rainfall that overwhelms drainage systems
- Storm surges from hurricanes or tropical storms
- River overflows due to excessive rainfall or snowmelt
- Dam or levee failures
- Flash floods caused by intense rain in a short period
Types of Floods
Understanding the different types of floods can help you assess your risk and prepare accordingly:
- Slow-Onset Floods – Develop over days or weeks, often caused by prolonged rainfall or snowmelt.
- Flash Floods – Occur suddenly, with little warning, often within minutes of heavy rain or dam breaks.
- Storm Surges – Powerful ocean waves pushed inland by hurricanes, causing severe coastal flooding.
Are You in a Flood Zone?
The Federal Emergency Management Agency (FEMA) provides flood maps to help homeowners determine their level of risk. Visit FEMA’s Flood Map Service to check your area’s flood risk.
How to Prepare for a Flood
1. Create an Emergency Plan
Every household should have a flood emergency plan. This includes:
- Identifying evacuation routes and meeting points
- Assigning roles to family members
- Preparing an emergency contact list
2. Build an Emergency Kit
Your flood emergency kit should include:
- Non-perishable food and bottled water (at least 3 days’ supply)
- First aid kit and essential medications
- Flashlights, batteries, and a hand-crank radio
- Important documents in a waterproof container
- Extra clothing, blankets, and hygiene products
3. Protect Your Property
Take proactive steps to minimize flood damage to your home:
- Elevate critical utilities like electrical panels and water heaters
- Install check valves to prevent sewage backup
- Waterproof your basement with sump pumps and sealants
- Clear gutters and storm drains to prevent water buildup
- Consider flood insurance, as standard homeowner policies do not cover flood damage
4. Don’t Overlook Your Water Supply
When a flood hits, clean water can quickly become a serious concern. Contaminated water isn’t always obvious—it might look clear but still carry harmful bacteria or chemicals. That’s why it’s important to think ahead. Store bottled water somewhere easy to grab if you need to leave quickly, and learn how to purify water if your tap becomes unsafe. If you rely on a well, extra precautions are essential to avoid long-term contamination.
We’ve put together a helpful resource that walks you through the steps. Here’s how to protect your water supply during a flood—because staying safe isn’t just about what’s around you, but also what’s going into your body.

What to Do During a Flood
1. Stay Informed
Monitor local weather reports and emergency alerts. Sign up for notifications from the National Weather Service (NWS) and FEMA.
2. Evacuate If Necessary
If authorities issue an evacuation order, leave immediately. Do not wait for confirmation of rising waters. Follow these guidelines:
- Take your emergency kit with you
- Avoid driving through flooded roads—just six inches of moving water can knock a person down, and one foot of water can sweep a vehicle away
- If trapped in your home, move to higher ground and call for help
3. Stay Away from Floodwaters
Floodwaters can contain debris, sewage, and hazardous chemicals. Never attempt to walk, swim, or drive through floodwaters.
Recovering After a Flood
1. Return Home Safely
Only return when authorities declare it safe. Be cautious of structural damage, gas leaks, and electrical hazards.
2. Begin Cleanup and Repairs
- Wear protective gear (gloves, masks, boots)
- Disinfect surfaces that came into contact with floodwaters
- Check for mold growth and remove wet materials
- Take photos of all damage for insurance claims
3. Seek Assistance
Flood recovery can be overwhelming, but help is available. Organizations like FEMA, the American Red Cross, and Hope Force International provide aid, temporary housing, and cleanup support.
