“FEATURE> THE NUANCED APPROACH
Designers from coast to coast are breaking through the old distinction between grey and green infrastructure to establish strategies that apply a mix of the two.

New York was still pumping Sandy’s surge-water out of its subway system when news headlines began to trumpet how best to ride out the next big storm—“NYC Sea Barrier: Its Time Has Come” or “Saving New York by Going Green”—leaving the impression that infrastructure could be neatly categorized into opposite kinds: grey vs. green or hard vs. soft. The thread that bound everything together was the promise of a more “resilient” New York. But the menacing irony here is that these kinds of easy dualisms have a lot to do with getting us to our present state of vulnerability in the first place. When the U.S. looks like a schoolroom map—blue for water, green for land, Mississippi River as a winding line, and barrier islands stretching out along the coast—it seems perfectly reasonable to build public housing on the Rockaways, industrial parks along the Gulf Coast, and cities in the Mississippi delta. In reality, though, coastlines are not lines at all, but zones of negotiation between land and sea, barrier islands are on the move (briskly so, on geological terms), and the delta is an impossible-to-distinguish mixture of water and land and everything in between. The climate-related risks we now face don’t hew to any dualisms. Floodwaters overwhelm dykes and dunes alike. Tornados and wildfires are blindly indiscriminate. And heat waves are just that: waves that lack clear boundary in space and time. It follows, then, that the strategies used to render our communities resilient from these risks must also emerge from this kind of nuance.”
