The Chulalongkorn University Centennial Park (CU Park) in Bangkok, designed by Thai landscape architect Voraakhom, offers a multifunctional green space that addresses the city's critical issues of sinking land and exacerbated flooding due to climate change. This park integrates recreational facilities with innovative water management and urban cooling strategies. It is estimated CU Park can retain approximately one million gallons of water during severe floods. Its design includes green pathways next to a reconfigured road, prioritizing bike paths and walkways over car lanes, and employs a gradual slope to utilize gravity for efficient water drainage from green roofs to a retention pond. This park exemplifies how urban design can harmonize with nature to tackle environmental challenges, promoting community engagement with the natural environment.
