Spring is coming. In Minnesota — and across North Dakota, South Dakota, Iowa, and Wisconsin — that means snowmelt, saturated ground, heavy rain, and rivers that don’t ask permission before they rise.
And every spring, the same conversation happens: a homeowner finds water in their basement or living room, calls their insurance company, and learns for the first time that their home policy doesn’t cover it.
Flood damage is the most expensive and most misunderstood coverage gap in American homeownership. 70% of annual flood losses in the U.S. remain uninsured — amounting to $17.1 billion in financial exposure every year. Much of that is not ignorance. It’s myth.
Here are the seven flood insurance myths we hear most often — and the truth behind each one.
Myth #1: “My homeowners insurance covers flood damage.”
This is the most costly myth in insurance. Standard homeowners policies — every single one, regardless of carrier — specifically exclude flood damage. It is not a buried exclusion. It is a fundamental limitation of the coverage.
If water enters your home from the outside — rising rivers, storm surge, heavy rainfall overwhelming drainage systems, snowmelt pooling against your foundation — your homeowners policy will not pay for it. Not a dollar.
What homeowners insurance does cover is sudden and accidental water damage from inside the home — a burst pipe, an overflowing appliance, a roof leak from wind. The moment water originates from the ground or outside your structure, you are in flood territory and your home policy steps aside.
Flood coverage requires a separate, dedicated flood insurance policy. Period.
Myth #2: “I’m not in a flood plain, so I don’t need flood insurance.”
This one gets people hurt more than almost any other myth on this list.
According to FEMA, roughly one-third of flood insurance claims come from properties outside designated high-risk flood zones. Properties outside the 100-year flood plain still have a 0.2% annual chance of flooding — and over a 30-year mortgage, that adds up to a meaningful probability that is easy to dismiss until it happens.
More importantly: FEMA flood maps are often outdated. Many of the maps currently used for insurance determinations are 10 to 15 years old. They were drawn based on historical rainfall data and land conditions that no longer reflect what’s happening on the ground. Development changes drainage patterns. Climate is producing more intense rainfall events. The Minnesota DNR has specifically documented that the state is seeing floods meeting or exceeding 100-year intervals more frequently than historically observed.
Your flood zone designation tells you what the rules require. It does not tell you whether your property will flood.
Myth #3: “I live in a 100-year flood plain — that means it only floods every 100 years.”
This is one of the most dangerous misunderstandings in all of risk management, and even some homeowners who carry flood insurance believe it.
A “100-year flood” does not mean a flood that happens once per century. It means a flood that has a 1% chance of occurring in any given year. Every year. Independently of what happened the year before.
Think of it like dice. Rolling a specific number doesn’t make it less likely on your next roll. A 1% annual chance means that over a 30-year mortgage, a homeowner in a 100-year flood plain has approximately a 26% chance of experiencing at least one flood event at that level during the life of their loan.
And that math is based on historical data — before accounting for the fact that Minnesota’s extreme rainfall events are increasing in frequency. The Mississippi River in St. Paul set a record in 2019 for the longest consecutive period above flood stage ever measured in the city — 42 straight days. Several communities in Minnesota and Iowa have experienced back-to-back “100-year” floods within a handful of years of each other.
The 100-year label describes probability, not schedule.
Myth #4: “A flood means water up to my waist — my house would never flood that badly.”
Most flood damage doesn’t look like the news footage. It doesn’t require boats in the street or water at chest height.
Just one inch of water inside a home causes an average of $25,000 in damage. Two inches. Six inches. A finished basement with an inch of standing water after a heavy rain event is a flood claim — flooring, drywall, personal property, electrical systems, appliances, all affected.
Flash flooding from an overwhelmed storm drain. Spring snowmelt pooling at a foundation. A low spot in the yard that channels water toward the house during a heavy rain. Surface water from a neighbor’s property. None of these require a river to overflow its banks. All of them are flood events that a standard homeowners policy will not cover.
In Minnesota and the upper Midwest, basement flooding from spring runoff is one of the most common property claims — and one of the most consistently uninsured.
Myth #5: “I can’t get flood insurance — my property isn’t eligible.”
Almost the opposite is true. Any homeowner, renter, or business owner in a community that participates in the National Flood Insurance Program can purchase flood insurance — regardless of whether their property is in a high-risk zone or not.
Minnesota communities that participate in NFIP — which includes the vast majority of incorporated cities and townships — make their residents eligible for federal flood insurance whether or not the property is in a designated flood zone. Minnetonka, for example, explicitly states on its city website that all residents are eligible for NFIP coverage.
Beyond NFIP, private flood insurance options have expanded significantly and are now available in all 50 states. If you’ve been told you can’t get flood coverage, the conversation likely needs to be with a different agent or a different market.
Myth #6: “Flood insurance is only for homeowners.”
Renters can purchase flood insurance for their personal belongings. The landlord’s policy — whether NFIP or private — typically covers the structure only. A renter’s personal property, electronics, furniture, clothing, and belongings are not covered by anyone’s policy except the renter’s own.
Business owners can purchase commercial flood insurance for their buildings, contents, and in some cases business income lost during a flood-related closure.
Flood insurance is available to homeowners, renters, condo owners, and business owners. The only requirement is that you’re in a community that participates in the program — and most communities in Minnesota and the surrounding states do.
Myth #7: “The government will bail me out if there’s a flood.”
Federal disaster declarations are not a substitute for insurance. Here’s why this matters:
First, a disaster declaration is not automatic. Your area has to meet specific thresholds of widespread damage before FEMA declares a disaster. Individual property losses, even severe ones, don’t trigger declarations on their own.
Second, even when a disaster is declared, FEMA assistance for individual homeowners is typically limited. The average individual assistance grant from FEMA has historically been well under $10,000 — nowhere near enough to cover significant flood damage to a home or its contents.
Third, FEMA disaster loans (through the SBA) are loans, not grants. You have to qualify, and you have to pay them back.
Flood insurance pays your claim regardless of whether a disaster is declared. That’s a fundamental difference that matters enormously when something actually happens.
Understanding your flood insurance options
Flood insurance used to mean one thing: NFIP. The National Flood Insurance Program, administered by FEMA, has been the backbone of flood coverage in the U.S. since 1968. For many homeowners — especially those with federally-backed mortgages in high-risk flood zones — it remains a required starting point.
But the market has changed significantly. Private flood insurance is now a genuine alternative, and in many cases a better one.
NFIP — The federal program
- Building coverage up to $250,000 for residential structures
- Contents coverage up to $100,000 for personal belongings
- Standardized policy — same coverage terms regardless of which company sells it
- 30-day waiting period before coverage takes effect (with some exceptions)
- Does not cover additional living expenses if you’re displaced from your home
- Does not cover basement contents or improvements in most situations
- Premiums have been increasing under FEMA’s Risk Rating 2.0 methodology, which aligns rates more closely with actual property-level risk
NFIP is the right answer for some homeowners — particularly those required to carry it by their lender, those in high-risk zones where private markets are more limited, and those who qualify for subsidized rates under the program.
Private flood insurance — the growing alternative
The private flood market has grown substantially in recent years, driven by improved risk modeling technology and carriers willing to compete on price and coverage. In 2025, 95% of homeowners seeking flood insurance meet private market underwriting standards, and up to 60% would pay less in the private market than under NFIP, according to research from Neptune Flood.
Key advantages private flood often has over NFIP:
- Higher coverage limits — private carriers can insure homes well above NFIP’s $250,000 cap, which matters for the majority of homes worth more than that today
- Additional living expenses coverage — pays for temporary housing if your home is uninhabitable after a flood
- Shorter waiting periods — some private carriers can bind coverage in as few as 10 days versus NFIP’s standard 30-day wait
- Broader contents coverage — more flexibility on what’s covered and how it’s valued
- Competitive pricing — particularly in lower-risk zones where NFIP rates have increased under Risk Rating 2.0
Neptune Flood
Neptune is the largest private flood insurer in the United States with over 250,000 policies in force and coverage available in all 50 states. Neptune uses AI-driven underwriting to deliver instant quotes and offers residential coverage up to $7 million — far beyond NFIP limits. Their platform allows independent agents like Mitchell Insurance Agency to quote and bind quickly without the delays of the federal program.
Aon Edge
Aon Edge, a division of Aon, has been in the private flood market since 2003 and offers two primary products: their EZ Flood standalone policy — available in high and lower-risk flood zones — and Excess Flood coverage for properties that need limits above NFIP’s cap. Aon Edge is AM Best rated A (Excellent) and covers homes up to $5 million in combined building and contents coverage. One significant advantage: no waiting period on Aon Edge policies, meaning coverage can be effective immediately.
NFIP through your agent
For homeowners required by their lender to carry NFIP, or those in zones where private markets are limited, the federal program remains the foundation. We can write NFIP coverage directly and compare it against private options so you’re making an informed decision rather than defaulting to whatever is available.
What flood insurance does NOT cover — regardless of policy type
Understanding the limits matters as much as understanding the coverage. Both NFIP and most private flood policies exclude:
- Moisture, mildew, or mold not directly caused by a covered flood event
- Earth movement related to flooding — landslides, sinkholes
- Sewer or drain backup unless it is directly caused by and occurring simultaneously with a flood
- Landscaping, decks, patios, fences, and swimming pools
- Vehicles — those go on your auto policy
- Temporary housing costs under NFIP (available under some private policies)
- Financial losses from business interruption under standard residential policies
Sewer backup is worth calling out specifically. A very common source of basement flooding in Minnesota is sewer or drain backup — water that comes up through floor drains or toilets during heavy rain when the municipal system is overwhelmed. This is not a flood as defined by either NFIP or most private flood policies. It requires a separate sewer backup endorsement on your homeowners policy. If you don’t have that endorsement, check — it’s one of the most affordable and most overlooked add-ons available.
The waiting period — why right now matters
NFIP has a standard 30-day waiting period before flood coverage takes effect. Most private flood options require 10–14 days. Some Aon Edge products have no waiting period.
What this means practically: you cannot buy flood insurance the day before a flood warning and expect coverage. Once a storm system is named or a flood watch is issued, many carriers will impose a moratorium on new flood policies entirely.
Spring flooding in Minnesota typically develops over days and weeks — snowmelt, saturated soil, rising rivers. The window to act is now, before the ground thaws, before the rivers rise, before the weather system that causes the problem is already on the radar.
How much does flood insurance cost?
It depends on your property’s flood zone, elevation, construction type, and coverage amount. But the range is wider than most people expect — and often more affordable than they assume.
In lower-risk zones, private flood policies can run as little as a few hundred dollars per year. In higher-risk zones, NFIP premiums under Risk Rating 2.0 are now calculated based on actual property-level risk and vary significantly. The best way to know your number is to get a quote — and to compare NFIP against private options rather than assuming one is better.
What doesn’t vary is the cost of not having it. One inch of water: $25,000. Most uninsured flood losses are not catastrophic events — they’re manageable events that become financially devastating only because there was no coverage in place.
What to do right now — before spring
- ☐ Check whether your home is in a designated flood zone — FEMA’s Flood Map Service Center at msc.fema.gov lets you look up any address
- ☐ Review your homeowners policy and confirm flood is excluded — it will be, but know it
- ☐ Check whether you have a sewer backup endorsement on your homeowners policy — if not, ask about adding one
- ☐ Get a flood insurance quote — both NFIP and private options — and compare
- ☐ If you’re renting, ask about contents-only flood coverage for your personal belongings
- ☐ If you own a business, ask about commercial flood coverage for your building and business income
- ☐ Don’t wait for a forecast to prompt you — the waiting period means you need to act before the risk is visible
A flood quote takes about 10 minutes. The conversation is free. And unlike most insurance decisions, this one has a hard seasonal deadline.
