There were a number of vacant lots, currently sporting brown puddles of floodwater shaped like the floor plans of houses that had once stood there. All the houses that hadn’t been torn down were now standing proud of the water. Some were on high foundation walls of reinforced concrete, enclosing garages or storage space, currently filled with water but, it could be guessed, easy to hose out and dehumidify when the waters receded. Others—and these looked newer and nicer—stood above the water on reinforced concrete stilts, connected to the ground by ramps or stairs of welded aluminum.
