Pretty much all of the Texas Gulf coast is built like that. There are some really great houses but all up on stilts. Most of them will have pre-set hole around the windows to make it easier to attach sheets of plywood. You're also meant to keep some windows open behind the plywood to equalise the pressure. Otherwise houses can blow their own roofs off due to the sudden swings in air pressure.
Hurricane Harvey made landfall in Texas at Port O'Connor where, clearly, flooding is not unknown.
