We broke ground last month on a Low Impact Development (LID) project in Taipei, Taiwan. This is our first LID project in Taiwan and one of the first LID demonstration projects in Taiwan using US design methods.
The project site is located at the Dihua Sewage Treatment Plant in Taipei. This LID retrofit project provides pervious parking space and connection pathways for staff and visitors. The total area is about 9,530m2, which includes 98 “green” vehicle parking spaces while protecting 111 existing trees. To collect, treat, and detain stormwater onsite, we designed subsurface gravel storage, porous asphalt, rain gardens, and constructed wetlands.
All the LID tools will be constructed and fully functional prior to the rain season. On average, Taiwan experiences three typhoons every year (July-September), providing much of the water supply, but also causing damage, flooding, and landslides. This new infrastructure will help build in resiliency to combat more intense storm events resulting from climate change.
