“When I started this job, people kept asking me, ‘Why do we have so much flooding now?’ and I said, ‘Well, there’s just one problem: The whole city’s four feet too low—that’s all!’” But as Miami Beach city engineer Bruce Mowry, the person responsible for maintaining and improving the island’s public infrastructure, steered his car through the Flamingo Park neighborhood this past January, his typically cheery mood dimmed. “You know, I drive around a lot, looking at all these streets and trees and homes and thinking about what’s coming,” Mowry said. “If we get the four feet of rise that’s predicted, all of this area will be two-and-a-half feet underwater.”
“This whole beautiful landscape’s going to change,” he said.
Miami Beach consists of a long, low barrier island accompanied by a scattering of manmade islets. It’s one of the lowest-lying municipalities in the country, and its residents are leading the way into the world’s wetter future. Along the island’s low western side bordering Biscayne Bay, people have come to dread full-moon high tides, when salt water seeps into storm-drain outlets and the porous limestone that provides the island’s foundation, forcing water up and out into the streets and sidewalks and threatening buildings and infrastructure.
