New York 2100 regularly experiences huge waves battering the eastern seaboard. “100-year floods” now occur every four years. However, residents along Brooklyn’s Gowanus canal are ready. Storm-surge barriers are set up near the opening of the canal while secondary barriers lying at the water’s edge are inflated. One last layer of defense lies in plant and artificial sponge islands. The park surrounding the canal is sloped and contoured to collect overflow water in designated areas, away from the site’s most valuable buildings. Meanwhile, tidal turbines beneath the surface of the water gather wave energy at the soft-edge boundary of the designated energy park. In 2100, New York is the storm energy capture center of the western hemisphere.
