One Mortgage, No Guarantees
The house has never flooded. Fifty years on a South Carolina marsh island, no claim, no damage. But the homeowner's flood insurance has more than doubled since 2023, and he refinanced this year just to keep the math working. His mortgage assumes twenty-some more years of stability. The federal flood insurance program that underwrites every coastal transaction around him expires September 30 and hasn't been guaranteed for longer than a few months at a time since 2017. Nobody can tell him what next year costs.

CONTINUE READINGOvernight, a Flood Zone
Karen Costello points visitors to the debris line near the top of her white fence. That's where six feet of floodwater stopped on March 20, after a Kona low pushed through her Ke Iki Road home in 45 minutes. Her children's photos are gone. Her tenant moved out. She had no flood insurance because she wasn't in a flood zone.
She still isn't. FEMA's redrawn maps take effect June 10, adding more than 4,000 O'ahu homes to mandatory flood zones for the first time. Ke Iki Road remains outside the lines. The maps modeled streams. What flooded Costello was rain pooling faster than a city drainage valve could release it.
Who Stays, Who Goes
The Sorting
On South Carolina's Grand Strand, no flood insurance requirement has become a luxury amenity. As FEMA reprices coastal risk one structure at a time, oceanfront lots sell for millions while the rows behind them go soft and retirees on Social Security drop their policies. Nobody announced this. The market is sorting who gets to live on the coast, one renewal notice at a time.
The Exit
Greinwich Terrace, in Lake Charles, Louisiana, flooded three times in nine months. The state offered $30 million to buy people out — a rare, structured exit from land the water wants back. One side of the road was demolished. The other side is still occupied, still flood-prone, waiting on funding that hasn't come. In eighteen days, even the program's website disappears.
