With unexpected climate causes heavy rainfall, low-lying cities across the globe are bracing for flooding disasters. As sea levels rise and concrete infrastructure multiplies, Bangkok is sinking 2 cm. every year. For the first time in 30 years, an invaluable land—11 acres of land and 1.3 km. avenue — was not turned into another commercial use. It is transformed into a public park. Chulalongkorn Centenary Park is the first critical piece of green infrastructure in Bangkok to mitigate detrimental ecological issues and reduce urban flood disaster risk. By harnessing the power of gravity, The park is able to collect, treat, and hold runoff. Sitting on a three-degree angle—leaving not a single drop of rain wasted, the park is able to hold up to a million gallons of water during heavy rainfall. The park is an example of various landscape solutions for urban flood reduction. It reminds the city how a park can help the city confronts climate change, to live with water, rather than fear it.
