A Green Infrastructure for a More Resilient City


The project site is a large 10-ha ravine area along the Sanya River, where the tides once encountered fresh water. Urban expansion later robbed this area from the river, confined between concrete flood walls and utilised as a dump for construction waste. The attentive re-modelling of the ground, based on the concept of “form follows processes”, represented the key to dealing with the different issues. The technique of cut and fill and the reuse of materials produced by demolitions of reinforced concrete elements created a new micro-topography with a fragmented morphology. The riverbank was transformed into a porous edge distinguished by an archipelago capable of channelling ocean tide waters into the park and protecting against the high winds of tropical storms and flooding caused by rainwater draining from inland areas. The line was extended, expanded, stretched from roughly 700 to 4,000 metres in length, with a depth of water that varies from 0 to 1.5 metres, creating a prolific aquatic environment.
