Check local hazard information, make an alert and evacuation plan, protect documents and valuables, review flood insurance early, and have a qualified local professional assess any structural retrofit. No household device or flood map can guarantee protection.
What kinds of flooding should you prepare for?
Coastal and atmospheric-river storms can create different, overlapping flood hazards. Coastal flooding can involve higher water levels and energetic waves. Storm winds push surge toward shore, while tides and other local conditions can add to water levels; wave action can increase the hazard and damage structures. FEMA’s coastal flood study guidance describes coastal flooding as typically involving increased water levels and/or high-energy wave action.

An atmospheric river is a concentrated flow of water vapor that can bring significant rain or snow. When moisture moves inland and rises over mountains, cooling can produce heavy precipitation. That rainfall or mountain precipitation can contribute to flooding away from the coast, including in river basins. FEMA’s Hoquiam North Shore Levee West environmental assessment describes atmospheric rivers in this context and attributes the underlying description to NOAA.

A sump pump, for example, is not a defense against wave action or fast-moving floodwater. Consider the likely source, depth, speed, duration, waves, and the building’s design before choosing a retrofit.

What should you do before storm season?
Learn your local risk and get alerts
Check local flood hazard information and sign up for alerts from local emergency officials. Treat maps as a starting point, not a guarantee: flooding can occur outside mapped hazard areas. Ready.gov’s flood guidance covers alerts, preparedness, and safety.
Make a household plan
Agree on evacuation routes, a meeting and communication plan, where to shelter if officials advise it, and how to account for pets and anyone who needs assistance. Practice the plan and keep needed supplies ready so you are not assembling them as a warning arrives.

Protect belongings and reduce avoidable water entry
- Store important documents in waterproof containers and keep password-protected digital copies.
- Move valuables and essential items to higher levels when possible.
- Clear gutters and drains before storms so debris is less likely to obstruct drainage.
- Where the home’s drainage and plumbing make them appropriate, consider a check valve or a sump pump with battery backup. These are conditional household measures, not protection against every flood mechanism.
Ready.gov recommends these kinds of household preparations, along with a practiced plan and supplies. Suitability of water-control equipment depends on the home and its drainage conditions.
Review flood insurance well ahead of a forecast
Standard homeowners insurance does not cover flood damage. Ready.gov says National Flood Insurance Program policies typically can take up to 30 days to take effect; that is a typical waiting period, not a guarantee for every policy or situation. Contact an insurer well before storm season to confirm eligibility, coverage, current terms, and when protection would begin.

Which home flood protections may fit your property?
There is no universal best retrofit. FEMA defines floodproofing as structural and non-structural changes that reduce or eliminate flood damage, but the acceptable methods depend on flood zone, building type, and applicable requirements. Compare the options against the property’s actual hazard and obtain professional advice before structural work.
| Measure | Where it may be relevant | Limits and cautions |
|---|---|---|
| Elevation | A home with significant mapped or recurring exposure may warrant an evaluation of elevation. FEMA’s mitigation project examples include elevating homes. | Site conditions, foundation, access, utilities, and code requirements need assessment. A project example does not establish that elevation is suitable or cost-effective for every property. FEMA’s mitigation project overviews provide examples, not property-specific recommendations. |
| Wet floodproofing | Some permitted enclosures or building situations may be designed to allow water to enter in a controlled way, using flood-resistant materials and systems. | It does not keep water out or protect contents, and specific rules apply. Check FEMA’s floodproofing guidance and local requirements. |
| Dry floodproofing | May be considered for certain nonresidential buildings in eligible A-zone situations if design and certification requirements are met. | Under NFIP rules, dry floodproofing is not permitted in Coastal High Hazard Areas. Pressure, leakage, flood duration, and wall strength matter, so professional design is essential. See FEMA’s floodproofing guidance and its 2020 code guidance. |
| Check valve or battery-backed sump pump | May help in a suitable home and drainage context as part of household preparation. | These devices do not address every flood source, wave action, or fast-moving water, and they do not replace alerts or evacuation instructions. Ready.gov recommends considering them where appropriate. |
| Community flood-control or watershed work | Local authorities may assess infrastructure, floodplain, or landscape approaches. FEMA’s project records include an atmospheric-river-related control spillway project in California. | A project in one watershed is not a recommendation for another. Local hydrology, environmental review, costs, and maintenance all matter. See the FEMA project overviews. |
For a structural proposal, ask a qualified local engineer or other professional experienced in flood mitigation to evaluate the flood source, mapped exposure, likely depth and velocity, waves, duration, foundation and wall design, utilities, and current code requirements. FEMA’s International Codes guidance explains why requirements and acceptable approaches vary by building and flood zone.
Rank #4
- COMPREHENSIVE FLOOD PROTECTION: Includes ten 5-foot water-activated flood barriers, providing up to 50 feet of coverage to manage leaks, spills, and flooding
- HIGH ABSORPTION CAPACITY: Each barrier absorbs up to 4 gallons of water, swelling to 3.5 inches high within minutes to form an effective barrier against water intrusion
- RAPID ACTIVATION: Barriers activate upon contact with water, expanding quickly to contain and divert floodwater without the need for sand or heavy lifting
- CONVENIENT STORAGE BUCKET: Comes with a durable, resealable orange bucket for organized storage and quick deployment during emergencies
- VERSATILE INDOOR & OUTDOOR USE: Suitable for protecting areas around doorways, garages, basements, and more from water damage. Not suitable for use with salt water, calcium, or chlorine
When comparing proposals, consider whether they protect the structure, utilities, and contents; whether the building can be safely evacuated; installation and maintenance demands; insurance coverage; and whether a community-scale solution is needed. A Base Flood Elevation (BFE) is FEMA’s defined elevation of surface water from a flood with a 1% chance of equaling or exceeding that level in any given year; it does not mean such a flood happens only once every 100 years. FEMA’s floodproofing glossary provides the definition.
Do these 3 things before closing this tab:

- Follow alerts and instructions from local officials and emergency services; evacuate when directed.
- Move to higher ground when officials advise it. Shelter in place only when authorities say it is appropriate.
- Do not assume a sump pump, portable barrier, or retrofit makes it safe to ignore an evacuation order.
- Do not walk, swim, or drive through floodwater, and do not go around barricades. Ready.gov warns that six inches of moving water can knock a person down and one foot can sweep a vehicle away. Stay off bridges over fast-moving water.
These are emergency safety steps, not a substitute for local, real-time instructions. A storm may bring rapidly changing water levels, and rainfall or river flooding can persist far from the shoreline.
