Homeowners who buy flood insurance from the federal government are closer to seeing relief, after the Senate passed a bill to delay premium hikes. The bill now goes to the House.

The bill would delay changes that were made two years ago to help fund the program better. But the changes caused rates to skyrocket, and homeowners in flood-prone areas who historically relied on the program couldn't afford insurance.

The bill was muscled through the Senate after angry constituents, the real estate and home builder lobbies inundated lawmakers with complaints. The legislation is a win for coastal state Democrats like Sens. Mary Landrieu of Louisiana, Bill Nelson of Florida and Bob Menendez of New Jersey, who have formed an unstoppable coalition with Republicans representing coastal areas and the Mississippi basin like Sen. John Hoeven of North Dakota.

The legislation will delay for up to four years huge premium increases that are supposed to phase in next year and beyond under new and updated government flood maps. It also would allow homeowners to pass below-cost policies on to people who buy their homes. People who have recently bought homes and face sharp, immediate jumps in their premiums would see those increases rolled back.

The measure faces a rockier climb in the GOP-controlled House, where Speaker John Boehner, R-Ohio, and Financial Services Committee Chairman Jeb Hensarling, R-Texas, prefer a more modest approach.

At issue is the government-run flood insurance program, in which taxpayers and other homeowners subsidize below-risk rates paid on older homes in both coastal areas threatened by hurricanes and big storms and inland areas near flood-prone rivers. A sweeping overhaul that passed virtually unanimously in 2012 was designed to make the federal flood insurance program more financially stable and bring insurance rates more in line with the real risk of flooding.

Opponents of the new legislation says it essentially unravels reforms to the much-criticized flood insurance program that put taxpayers on the hook for $24 billion in losses by subsidizing ownership in risky areas. The changes were aimed at making the program more financially sound and putting a stop to homeowners in less risky areas essentially subsidizing below-market insurance rates for homeowners in locales more at risk of flooding.

However, projections of the new rates have caused anxiety among hundreds of thousands of homeowners. The loss of subsidies when homes are sold has put a damper on the real estate market and threatened home values. Some homeowners are caught in a Catch-22. They face rates that, once phased in, they won't be able to afford. But because of the higher insurance rates, they also face having to sell their properties at distressed prices.

For instance, a North Dakota couple, Allison and Kyle Skari, bought a home in Grafton a year ago and initially paid $901 a year for $100,000 of coverage. They were hit with a $4,200 bill now and tell Sen. Heidi Heitkamp, D-N.D., that they never would have bought the home. They're ineligible for a phase-in of the higher premium because they bought after the 2012 law was passed but would get relief under the Senate bill.

Supporters say the bill buys time for the government to conduct a study of the affordability of flood insurance and for lawmakers to devise ways to help poorer people and the working class keep their homes.

The bill, however, contains no relief in the offing for 1.7 million owners of second homes, who are not covered by the Senate bill and who face annual 25 percent increases - provided they owned their home before Congress overhauled the program in 2012. They say the premium hikes threaten the viability of older beachfront towns.

The program helps 5.6 million policyholders, 20 percent of whom receive subsidized coverage for older homes built before communities joined the flood insurance program.

Under the 2012 changes, owners of second homes, frequently flooded properties and businesses in flood areas would gradually lose their subsidies and pay 25 percent more a year until they reach an actuarially sound rate. Others can keep their subsidies but can't pass them on when selling their homes. People who bought their homes after the legislation passed in July 2012 are subject to immediate jumps to actuarially sound premiums.

The 2012 law also phases out below-market rates for owners of grandfathered properties - those that were built in compliance with earlier flood risk estimates but whose risks have increased under new maps. Those homeowners would see their flood risks re-estimated and would see higher rates phased in over five years, so they could face premium jumps that are severalfold.
