On an exclusive Connecticut peninsula, where signs warn outsiders to stay off private roads, eight multimillion-dollar homes with sprawling yards along Long Island Sound are poised to become eligible for taxpayer-funded disaster aid.

That’s despite the fact that the Fenwick neighborhood of Old Saybrook is in a potentially perilous position, hovering where the Connecticut River meets the sound. A 1938 hurricane washed many Fenwick homes out to sea, including that of Katharine Hepburn’s family.

The eight homes, a short distance from the rebuilt Hepburn house where the actress died in 2003, currently lie in a coastal protection zone that bans homeowners from receiving federal funds to fix storm damage. The goal is to create a disincentive for new development in areas vulnerable to storms. Half the homes were built after the zone was created nearly four decades ago.

But a proposed massive overhaul of the protection system to correct mapping mistakes and other errors would lift the prohibition on aid for the Fenwick homes and more than 900 other structures along the East Coast from New Hampshire to Virginia. That would allow the owners to buy lower-cost flood insurance backed by the federal government and potentially benefit from millions of dollars in other federal aid to fix infrastructure including roads and bridges.

The proposed changes, expected to go before Congress for approval next year, are drawing criticism from watchdog groups that say making so many more properties eligible for federal aid would stress already strained disaster relief programs and is a step in the wrong direction at a time when scientists expect stronger and more frequent storms because of climate change.

“I’m concerned about federal subsidies going to people who, quite frankly, don’t need it,” said Steve Ellis, vice president of Taxpayers for Common Sense, a Washington, D.C.-based group that describes itself as a nonpartisan government spending watchdog. “The idea was you can develop in these areas but don’t expect any support from the federal government. You want to build, it’s on your dime.”

The National Flood Insurance Program is already more than $20 billion in debt and it could be drained of hundreds of millions of dollars more by the mapping changes. The federal government also could be on the hook for millions of dollars more in disaster aid payouts through the Federal Emergency Management Agency to fix storm damage to infrastructure.

Officials with the Fish & Wildlife Service said the properties on which the structures in question were built were mistakenly included in the national Coastal Barrier Resources System, which was created in 1982.

The mapping changes affect some of the country’s ritziest waterfront communities, and that has led some to question whether the wealthy are being given an unfair break. In New York’s Southampton, for instance, a boundary line has been shifted slightly to make a nearly $18 million beachfront home and another property eligible for aid.

It was a Fish & Wildlife Service review of the maps, not requests from property owners, that spurred the changes, agency spokesman Brian Hires said.

In the case of the Fenwick properties, Hires said the proposal simply corrects past mistakes: Officials now argue that the original determination that there wasn’t enough development on the lands to keep them out of the system was wrong and thus the properties should never have been in the protection zone.

Several Fenwick homeowners did not return messages seeking comment, while others did not want to comment publicly.

The Coastal Barrier Resources System – which now includes 3.5 million acres along the Gulf of Mexico, the Atlantic Ocean, the Great Lakes as well as in Puerto Rico and the U.S. Virgin Islands – saved the federal government $9.5 billion in disaster aid payouts from 1989 to 2013, according to a recent study by academic researchers. Not taking the current proposal into account, the system is projected to save another $11 billion to $108 billion by 2068, the study said.

Over the years, however, Congress has removed hundreds of properties from the protection zones. In December, President Donald Trump signed a bill that removed about 500 structures, with officials again citing past mistakes.

Mistakes or not, some experts are surprised the government would want to make many properties newly eligible for disaster aid, given concerns about climate change.

“That doesn’t seem like the move we should be making right now,” said Dylan McNamara, a physics and physical oceanography professor at the University of North Carolina at Wilmington. “We should be looking toward the future and admitting that the entirety of the coast is in a precarious position.”
