A Choice Was Made

Suffolk County took quite a blow from Isaias last week. And if the track of the hurricane-turned-tropical-storm was 50 miles farther east when it hit us, it would have been much worse here.

With gusts reaching more than 70 mph, there was a significant and extended loss of electricity from trees having fallen on electric lines and a shutdown of the Long Island Rail Road from trees falling on tracks. Fortunately, it was a fast-moving and thus relatively short-lived storm with punches of fierce wind rather than days of rain.

The bad news: It was a sampling of what’s ahead.

“Going forward, because of climate change, it will not be unusual for the Northeast to experience hurricanes with great intensity and frequency,” says Kevin McAllister, founding president of the Sag Harbor-based organization Defend H20.

Hurricanes and tropical storms feed on the warmth of water over which they travel, and climate change has been causing an ever-higher temperature in water bodies worldwide, resulting in more extreme and more frequent hurricanes — and earlier ones.

Isaias was the ninth named storm in the Atlantic hurricane season and the earliest “I”-named storm on record. The season began on June 1 and runs to November 30.

“What a fast start,” commented Ken Graham, director of the National Hurricane Center, was saying on TV as Isaias was percolating. He predicted that because of “warm water” it would continue to be an “active” season. Late last week, the number of named storms and hurricanes the Climate Prediction Center of NOAA forecasts to hit the Eastern Seaboard, including Long Island, this year was increased to a total of 19 to 25, up from 13 to 19.

Meanwhile, on Long Island, says Mr. McAllister, an experienced and credentialed marine scientist, “incrementally we are walling off the coast with bulkheads and rock revetments” — not allowing nature to maintain a coastline that can deal with storms. “The natural system involves a dune, which is a sand reservoir and shock absorber,” he explains. “It’s a beach-dune system.”

On Long Island, a good chunk of Montauk has become a poster child for dune destruction and the folly of then trying to deal with storms by artificial means. The “primary dune” of a major section of the oceanfront of Montauk was eliminated decades ago for the construction of a string of mainly motels.

In recent years, a choice was made. It was either relocating mainly 10 or so motels and also condos and other structures, rebuilding the dune, and allowing “the natural coastal process” — the dynamic process that nature provides — to return. Or — and this is what happened in 2015 — following the prescription of the U.S. Army Corps of Engineers: placing 14,200 jumbo “geotextile” sandbags, each 1.7 tons, in front of the buildings to try to protect them. The construction cost: $8.9 million.

Suffolk County government went along with this.

Indeed, a deal was cut in which you, dear reader, if you pay taxes in Suffolk County, are obligated to pay half the cost of “maintenance” of the sandbags, with the Town of East Hampton paying the other half.

The Town of East Hampton in a “hamlet study” subsequently recommended the relocation plan. But, since then, the town reversed itself, because of “pushback primarily from the business community in Montauk,” says Mr. McAllister, adding, “It is very disappointing.”

And in addition to Montauk, there are examples throughout Suffolk County of the mistake, still happening now, of “armoring” the shoreline. That next week.

Also next week: Details on an important report just released by the U.S. Government Accountability Office, which says “millions of Americans live in coastal areas threatened by sea level rise, and in all but the very lowest sea level rise projections, the retreat of people and infrastructure due to climate change will become an unavoidable option in some areas along the U.S. coastline.” It says “Congress should consider establishing a pilot program … and provide assistance to communities that express interest in relocation as a resilience strategy.”
