Inevitably it seems that rivers are one of two things to a city: either a vital, vibrant artery stitching it historically together (think the Seine through Paris, the Sumida through Tokyo, or the Chicago River through the downtown Windy City), or an industrial, black water pipeline which, decade after decade, sacrifices a thriving, walkable waterfront for a persistent no man’s land of warehouses, ports, power plants, and sewage treatment facilities (think the Delaware River in Philadelphia).
