Chulalongkorn University Centenary Park
For the first time in 30 years of rapid urban development, an invaluable property at the heart of Bangkok—11 acres of land and 1.3 kilometres of avenue—was not turned into another commercial use. Instead, it has been transformed into a public park. Opened in 2017, Chulalongkorn Centenary Park is the first critical piece of Green infrastructure in Bangkok to mitigate detrimental ecological issues and reduce urban flood risk.
By harnessing gravity on a three-degree gradual incline, the park is able to
collect, treat and hold run-off. It is able to hold up to a million gallon of water during heavy rainfall with its green roof, wetlands, detention lawns and retention pond. The rain and run-off are absorbed into the park‘s topography to generate a complete water circulation system.
The first of its kind in Bangkok, the 1.3-kilometre road running perpendicular to the park was revamped to shift priority from cars to foot and bicycles. By reducing four-vehicle lanes into two and enlarging them each from 12 to 30 metres, the once heavily-congested street now seamlessly connects pedestrians and cyclists directly to surrounding neighbourhoods and roadways that are linked to the city’s major residential, entertainment and retail facilities. The park is lined with corridors of rain gardens on both sides to provide shade and reduce run-off from the road surface.
