According to FEMA, over 13 million U.S. homes are at risk from coastal flooding. Rising sea levels and increasingly severe storms are becoming a part of daily life for millions of Americans living near the shore. So how can homeowners in flood-prone areas protect their home from flooding?
Here are six key questions to help coastal residents prepare for the next storm.
1. Is your property located in a flood-risk zone?
Before investing in protection measures, the first step is to understand your level of exposure. You can check FEMA’s Flood Map Service Center (MSC) to identify your Flood Zone (A, AE, VE, etc.) and whether you’re in a Special Flood Hazard Area (SFHA).
Your home isn’t right on the coast? Bear in mind even homes several blocks inland can experience flooding from storm surge, high tides, or heavy rainfall.
Tip: Check whether your community participates in FEMA’s Community Rating System (CRS). The program rewards cities that take proactive flood prevention measures by offering homeowners discounts on flood insurance premiums.
Your city’s flood management performance greatly affects your insurance bill. When a city fails to apply or maintain its CRS status, as happened recently in Boston, homeowners can collectively lose out on hundreds of thousands of dollars in potential insurance savings.
2. How Flood-Resistant is Your Home?
The best way to protect your home from flooding is to make sure the building envelope and foundation can handle water intrusion. Review these common weak points:
- Ground-level doors, garages, and vents.
- Gaps around utility lines and air vents.
- Foundations without proper drainage or sealing.
Pro tip: Install removable flood barriers at entry points. These cost-effective, reusable, and less intrusive installations may drastically reduce the damage in a flooding event.

3. Are your electrical and mechanical systems above flood level?
In many flood-prone areas, electrical systems, HVAC units, and water heaters are damaged first.
To prevent this:
- Establish your Base Flood Elevation (BFE), as in how high the water might get in your home during a flooding event. A local Flood Insurance Rate Map (FIRM) should indicate this information.
- Elevate outlets, circuit panels, and appliances at least 12 inches above your BFE.
- Move heating and cooling systems to higher floors, or raised platforms, if possible.
- Avoid storing flammable or toxic products in basements.

4. Do you have an emergency plan in case of flooding in your home?
Physical barriers are important, and so is preparation. When a Coastal Flood Warning or Storm Surge Watch is issued:
- Shut off power and gas before water enters your home.
- Move important belongings and documents upstairs.
- Keep an emergency kit with flashlights, batteries, water, non-perishables, and medications within easy reach.
- Stay informed through NOAA Weather Radio.
Tip: Sign up for FEMA Alerts and your local Emergency Management Office notifications to receive early warnings in real time.
5. What does your flood insurance actually cover?
Financial preparedness matters. Standard homeowner’s insurance policies do not cover flood damage. Only policies from the National Flood Insurance Program (NFIP) or private insurers do.
Make sure your coverage includes:
- Building structure and foundation
- Electrical and plumbing systems
- HVAC equipment, flooring, and built-in furniture
Something to keep in mind: As mentioned earlier, your premiums may be influenced by your city’s flood management rating under FEMA’s Community Rating System (CRS). A community’s flood resilience directly affects its inhabitants before the storm even strikes. Strong prevention efforts can help homeowners secure lower insurance rates.
Pro tip: Document your property with photos and receipts. This will speed up the claims process after a flood event.

6. How to further protect your home from flooding?
Having a broader resilience mindset is key as flood risk may intensify or shift over time. Homeowners can benefit from adaptive or nature-based solutions.
- Removable flood barriers offer flexible, temporary protection during storm surge events.
- Backflow preventers and check valves stop water from backing up into your home through drains.
- Nature-based solutions like landscaping and rain gardens help slow or redirect runoff, and absorb excess water.
Spending time and resources on preventing damage may help avoid heavier damage and rebuilding every storm season.
Flood-proofing Your Home Starts With Anticipation
To protect your home from flooding means thinking ahead. By knowing your risk, reinforcing key systems, and understanding how community flood management affects your insurance, you can dramatically reduce both physical and financial impacts starting today.
