Cities Can’t Prejudge Winner in Green v. Grey Infrastructure Battle
One of the ironies of the green versus grey infrastructure battle is that they are not mutually exclusive approaches; many times the best design solution is a combination of grey and green infrastructure working together. Grey and green infrastructure are on the same team, and that team’s goal is to take action on any number of difficult problems coastal cities are grappling with: hurricane risk, saltwater intrusion, coastal erosion, tidal flooding, sea level rise. Arguing about green versus grey infrastructure makes taking action on these problems harder than it already is.
