Next C Water City is a new, fully self-contained sustainable city planned for 500,000 residents. Water was central to the Next C planning concept, supplied by two adjacent rivers and monsoon rains. The city is a system of wetlands, rivers, lakes, and canals, cleansing the water from up-river communities and managing floods during the monsoon season. Working with SOM’s urban design team, Thomas Balsley Associates strategized an open space plan that consisted of seven primary landscape typologies: Central Parks, Civic Squares, Urban Promenades, Water Edge Parks, Canal Parks, Neighborhood Parks, and Wetland Parks filtering and polishing poor quality water from the Chaobai River prior to discharging into the new city’s extensive waterways and eventually into the Yongding River. Each open space typology collectively provides green links throughout the city, and open space programming relates directly to adjacent land uses. Parks along waterways were designed with each season’s environmental extremes in mind, from dry to flooded, creating unique parks for every season.
