Kunshan, China, located near Shanghai, has experienced unprecedented population and business growth in recent years which has resulted in environmental degradation and the need for the city to reshape its identity. SWA’s proposal aims to create a new waterfront district providing businesses as well as residents with public amenities and viable open space. The master plan balances development and environmental conservation on the Wusong Riverfront by employing highly detailed infrastructural systems that integrate cutting-edge hydrological design and land planning. The water treatment system acts as the central organizing structure of the site by introducing a sequence of several pools and channels that remove targeted pollutants by settling, filtration, aeration, and bio-processing in alternating oxic and anoxic environments. Existing storm pipe outlets that previously discharged directly into the inner bay are retrofitted, allowing water to pond onsite and flow over land in bio-swales before entering the treatment system or inner bay. SWA’s design also seeks to reconnect the population and river by maximizing the waterfront edge for varying scales and layers of experience. The perimeter of the bay is designed as an open space system with interconnected bicycle and pedestrian paths. Sustainable systems created by the compact master plan create a comfortable outdoor microclimate, encouraging people to use alternative, eco-friendly means of transportation. By designing a comprehensive sustainable network of water-cleansing and climate improving systems, the project exceeds development objectives while creating a new riverfront park for the residents of Kunshan.
