While locals in the community of roughly 350 dismiss that timeline, there is a consensus among scientists and residents that the island needs help. Still unsettled is what form that help might take—and what it would cost.⁠ ⁠ Small, low-lying communities along the East and Gulf coasts of the U.S. face uncertainty over whether lawmakers, and their fellow citizens, will deem their homes worth protecting.⁠ ⁠ Tangier Island has given up 70% of its land since 1850 and covers the equivalent of 1.1 square miles, said David Schulte, an Army Corps of Engineers marine biologist. It provides a stopover for migrating birds and supports the sea grass that crabs need. A 2021 study he co-wrote found that homes and roads will need to be raised by 10 feet over the next few decades. Such an effort, plus protecting vulnerable shoreline with rocks, could run $250 million to $350 million, the study said.⁠ ⁠ “If you’re going to make decisions solely on a strict cost-benefit analysis, the Tangiers, the small towns all over the U.S. coast, will lose, and all of our money will get directed toward shoring up big cities,” he said.⁠ ⁠ On Tangier, there is no talk of collective retreat. “We’re very savable, and I believe we’ll get there,” said Mayor James “Ooker” Eskridge, 65, a waterman who said his roots on the island go back to the late 1700s. He said the town most needs a rocky sea wall on its east flank to combat erosion.⁠ ⁠ Read more at the link in our bio.⁠ ⁠ 🎥: @k_zeisy for @wsjphotos」8月24日 0時34分
