We have been so far been considering the past. The Brooklyn waterfront, which was so radically altered by changes in shipping technology, is facing, like all coastal cities, the effects of global warming. Certainly, all of the architects in the Rising Tides exhibit at MOMA are in tune with Betsy McCully’s suggestion that soft solutions to storm surge and flooding will be more effective than hard ones. Two of the architectural teams designing for the exhibit developed ideas for sites on the Brooklyn waterfront: New Aqueous City and Oyster-Tecture. Can you imagine a future where either one of these visions might become a reality? Oyster-Tecture points back to the past of the Gowanus. While this project couldn’t ever be a restoration, could it be considered a monument to a long-gone ecology?
