Atelier Dreiseitl was commissioned to create a new city vision for Taipei. A humid subtropical climate, subject to typhoons, makes flooding a common occurrence, while the local Keelung River has been seriously degraded. In recent years, an annual rainfall of 2000mm has been augmented by typhoons adding the same volume of water in a few days. Heavy clay soils compound the challenge of working with rain in situ in this dense city. Rescuing, the almost extinct, local paddle fish became the caption for a project which creates fresh and lively public realm and intrinsically manages rain as a city resource on a local level.
A water sensitive urban design highlights tree avenues connecting subsurface retention channels and supplying the nearby Keelung River with clean water. A central park brings a breath of fresh air to the city and an urban lake balances typhoon rains. 50% of rainfall is managed on site and a flood strategy accommodates a 1 in 100 year flood event.
Pedestrian streetscapes link public transport to local destinations. Mixed-use neighborhood spaces promote dynamic living, working, socializing and recreation. The water sensitive detailing improves air quality and microclimate, making the city attractive and comfortable.
This project was carried out by Atelier Dreiseitl, now member of the Ramboll Group.
