Prepare for two different problems at once: keeping people and pets alive, and limiting damage to the building and its contents. Evacuation orders, avoiding floodwater, and following emergency instructions always take priority over sandbags, pumps, or any other property measure. The right building work depends on your home’s construction, local flood exposure, and whether you own or rent.
Start before a storm is nearby. Check official flood information and alerts, make an evacuation and communication plan, protect utilities and valuables from water, review insurance exclusions and waiting periods, and keep supplies ready. Use the steps below as a practical U.S. checklist, then confirm structural changes with a qualified local professional or your landlord.
1. Check your flood risk and turn on reliable alerts
Look up your address in FEMA’s Flood Map Service Center and read your local emergency-management guidance. A map helps identify mapped hazards and insurance requirements, but a boundary is not a guarantee that water cannot reach your property. Ready.gov’s plain-language warning is: “Where it can rain it can flood.” Intense rainfall, drainage failure, overflowing streams, storm surge, and sewer backups can affect places outside a mapped high-risk zone.
Use more than one warning channel
- Sign up for county, city, or tribal emergency alerts and enable wireless emergency alerts on your phone.
- Monitor the National Weather Service, local officials, and emergency-management accounts for watches, warnings, road closures, shelter information, and evacuation orders.
- Keep a battery-powered or hand-crank way to receive information if electricity or mobile service fails.
- Write down the address and phone number of your local emergency-management office, utility providers, insurance company, and an out-of-area contact.
Do not wait for water to appear before deciding what to do. Ask local officials which routes flood first, where official shelters accept pets, and which destinations are outside the evacuation area.

2. Build a household plan, including pets
A building plan cannot protect someone who is trapped on a road or stays behind after an evacuation order. Use the planning checklists on Ready.gov’s flood page and write down decisions while everyone is calm.
Decide when and where you will leave
- Choose at least two evacuation routes and a destination outside the threatened area. Route them in advance, then check official instructions because roads and bridges can close.
- Choose a meeting place if household members are separated and an out-of-area contact who can relay messages.
- Set a departure trigger that does not depend on a last-minute road check. Leave immediately when officials order evacuation; do not drive around barricades.
- Plan for children, older adults, disabilities, medical equipment, service animals, and pets. Confirm which hotels, relatives, shelters, or boarding facilities will accept animals.
Assemble supplies for several days
- Drinking water and ready-to-eat food for each person and pet, plus a manual can opener.
- Prescription and essential over-the-counter medicines, a first-aid kit, glasses, and copies of prescriptions.
- Phone chargers, power banks, spare batteries, flashlights, and a battery or hand-crank radio.
- Pet carriers, food, water, medication, vaccination records, leashes, and waste bags.
- Sanitation items, sturdy shoes, weather-appropriate clothing, blankets, cash, and basic tools.
- Fuel planning: keep vehicles maintained and filled when a threat is possible, without taking unsafe risks during an active emergency.
Protect critical records
Put insurance information, identification, deeds or leases, medical records, prescriptions, and emergency contacts in a waterproof container that you can carry. Ready.gov also recommends password-protected digital copies; store them in a secure account that household members can access if the originals are lost. Never post scans publicly or leave passwords with the documents.
3. Reduce preventable water entry and damage
FEMA describes property protection as a range of measures, from routine maintenance to major elevation work. None is a universal fix, and official sources do not provide controlled product rankings or a guaranteed level of protection. Match each action to the type of water your property faces, available power, maintenance needs, and owner approval.

| Measure | Primary exposure addressed | Scale and requirements | Important limits |
|---|---|---|---|
| Clear gutters, downspouts, roof drains, and yard drains | Rainfall entering or pooling around the structure | Simple recurring maintenance; confirm downspouts discharge away from the foundation where local rules allow | Cannot stop regional flooding, storm surge, or water entering through walls and floors |
| Sewer-line check valve | Floodwater or sewage backing up through drains | Plumbing installation; requires correct sizing, access, and periodic inspection | Does not prevent surface water from entering through doors, windows, or foundation cracks |
| Water alarm | Early detection of leaks or rising water indoors | Low-complexity device; place near sump pits, water heaters, furnaces, and low points | Needs working batteries and someone able to hear or receive its alert |
| Sump pump with battery backup | Standing groundwater or seepage in a basement or low area | Installation plus a maintained backup battery; test before storm season | Requires a suitable drainage system and does not make a basement flood-proof; a prolonged outage can outlast the battery |
| Elevate furnace, water heater, and electrical panel | Damage to susceptible utilities | Major work requiring code compliance and qualified contractors | Feasibility depends on the building and local flood depth; never improvise electrical work |
| Basement waterproofing | Water entering through basement walls, floors, or joints | Property-specific design and substantial installation | Waterproofing methods differ by soil, groundwater, foundation, and flood source; it is not a substitute for evacuation |
| Plywood, plastic sheeting, and sandbags | Short-term protection of selected openings or belongings | Buy and store materials before supplies become scarce; installation takes people and time | Sandbags and barriers can fail in deep or fast water and may redirect water; follow local guidance |
| Elevate the building | Repetitive or severe flood exposure | Large investment requiring engineering, permits, and local floodplain review | Appropriate design, cost, and eligibility are site-specific; no universal effectiveness figure is established |
Do the routine work first
- Remove leaves and debris from gutters, downspouts, storm drains, and street-facing grates.
- Check that drains are not blocked by stored items, mulch, or outdoor furniture.
- Inspect the roof, flashing, windows, doors, and foundation for conditions that allow heavy rain inside; arrange repairs while contractors can still work safely.
- Keep valuables, electronics, chemicals, and irreplaceable items on upper levels or on raised shelving. Do not store them directly on a basement floor.
Plan powered equipment for an outage
A battery-backup sump pump is an optional property-preparation purchase specifically identified by FEMA and Ready.gov. It can help when groundwater rises during a power failure, but it is not a guarantee against flood damage. Choose equipment appropriate to the pit and discharge arrangement, maintain the battery as the manufacturer requires, and test the system before a storm. A water alarm can provide earlier warning, but it also depends on charged batteries, correct placement, and someone receiving the alert.
Handle structural work carefully
FEMA’s hurricane guidance also lists sewer check valves, basement waterproofing, utility elevation, and building elevation in repeatedly flooded areas. Ask a licensed local professional about flood depth, foundation type, electrical and plumbing codes, permits, drainage impacts, and whether the proposed work could affect insurance or future resale. A renter should not alter plumbing, electrical systems, walls, or exterior grading without written permission from the landlord or property manager; report leaks, blocked drains, and unsafe utilities promptly.
4. Review flood insurance before a storm
General homeowners’ or property policies ordinarily do not cover flood losses. Ready.gov says separate flood coverage may be needed, while FEMA identifies National Flood Insurance Program coverage in participating communities. Coverage, exclusions, deductibles, contents limits, eligibility, and claims rules depend on the specific policy and location, so ask an insurer or the NFIP for written details.

Ready.gov’s current guidance says flood insurance typically takes up to 30 days to take effect. That waiting period means buying a policy after a hurricane is forecast may not protect against that event. Ask well before hurricane season whether your policy covers storm surge, surface water, sewer backup, temporary living expenses, basements, vehicles, and personal property, and ask when each coverage becomes effective. Keep the declarations page, policy number, agent contact, and inventory with your emergency records.

- Collect plywood, plastic sheeting, sandbags, towels, buckets, and cleaning supplies if those materials are appropriate for your property. Do not delay evacuation to install them.
- Fill vehicle fuel tanks when practical, place emergency kits where they can be carried quickly, and tell your out-of-area contact your destination.
- If evacuating, shut off utilities only as instructed by local authorities or utility providers. Leave early using the designated route.
6. Stay safe during flooding and heavy rain
Never walk, swim, or drive through floodwater. FEMA’s 2025 flood hazard information sheet says six inches of fast-moving water can knock a person down and one foot of moving water can sweep a vehicle away. These are FEMA safety figures, not a guarantee that shallower water is safe: depth, speed, hidden holes, debris, contamination, and electrical hazards are difficult to judge from a vehicle or sidewalk.
- Obey evacuation orders immediately and never drive around barricades.
- Do not touch electrical equipment if it is wet or if you are standing in water. Stay away from downed lines and report hazards to the utility.
- Move to higher ground if instructed, but do not enter a closed attic where rising water can trap you. If floodwater enters the building and escape is cut off, go to the highest safe level and signal for help.
- Keep children and pets away from floodwater, storm drains, culverts, and electrical equipment.
- Do not use a generator, grill, camp stove, or fuel-burning appliance indoors, in a garage, or near doors and windows; follow the equipment instructions and local emergency guidance.
7. Return and clean up only after officials say it is safe
Wait for local authorities to authorize reentry. Roads, bridges, buildings, drinking-water systems, and electrical networks may remain dangerous after rain stops and water recedes.
On the first inspection
- Assume floodwater is contaminated. Wear waterproof gloves, boots, eye protection, and other protective gear suitable for the debris and cleanup.
- Do not assume tap water is safe. Check with the local health department or water utility for boil-water notices and testing instructions.
- Look for structural damage, gas odors, damaged wiring, unstable ceilings, mold, wildlife, and displaced debris. Leave and call qualified professionals when conditions are unsafe.
- Do not switch on wet electrical equipment or utilities. Have the relevant utility or a qualified professional inspect systems before use.
Document damage before disposal when possible
Photograph and video every affected room, exterior elevation, appliance, utility, and item of personal property. Record the date, water height, visible source of water, cleanup actions, and emergency expenses. Contact your flood insurer promptly and keep receipts. FEMA’s flood information sheet recommends hiring a qualified flood adjuster before attempting cleanup or repairs; verify licensing and claims procedures with your state and insurer because those requirements vary locally.

Prevent additional damage only when it is safe and your insurer permits it. For example, you might board a broken window, remove standing water with appropriate equipment, or move undamaged belongings to a dry location. Keep damaged materials for inspection when practical, and do not make permanent repairs before the insurer has documented the loss unless an emergency requires it.
8. Avoid common preparation mistakes
- Treating a flood map as a guarantee: rainfall, drainage failures, and storm surge can flood areas outside mapped boundaries.
- Relying on sandbags alone: they are temporary materials, require advance setup, and can fail in deep or fast water.
- Buying insurance after the forecast: Ready.gov says coverage typically takes up to 30 days to begin, subject to the policy’s terms.
- Ignoring sewer backup: clear drains and ask a qualified plumber whether a check valve is suitable for your sewer line.
- Putting all valuables in one low room: distribute critical items to higher levels and maintain protected digital records.
- Planning only for the building: include pets, medicines, mobility needs, transportation, chargers, and a destination outside the evacuation area.
- Returning because the rain stopped: wait for an official reentry notice and treat water, wiring, structures, and drinking supplies as potentially hazardous.
9. Choose the next step by your situation
If you rent
Ask the landlord or property manager about the building’s flood history, drainage, sump equipment, utility elevation, emergency shutoffs, and evacuation procedures. Request repairs in writing and keep copies. You can independently prepare documents, supplies, alerts, a go-bag, and renter’s insurance questions, but do not modify plumbing, electrical systems, grading, or structural elements without approval.
If you own a home with occasional heavy-rain problems
Begin with drainage maintenance, roof and foundation repairs, elevated storage, alerts, a household plan, and insurance review. Add a water alarm or a properly maintained battery-backup sump pump when the building’s drainage design supports it. Have a professional assess recurring seepage before choosing waterproofing or a check valve.
If your property floods repeatedly
Ask local floodplain officials and qualified engineers about elevation, relocation, floodproofing, drainage changes, and available mitigation programs. Building elevation is a major project, not a last-minute storm task. Confirm permits, code requirements, financing, insurance implications, and whether the proposed work could redirect water toward neighboring properties.
The most important preparation is a sequence: know your risk, receive authoritative warnings, leave when ordered, keep people out of floodwater, and only then use property measures to reduce damage. Maintenance and upgrades can improve resilience, but they never replace evacuation and life-safety decisions.
