A Flood Adaptive Landscape: Yanweizhou Park in Jinhua City - 9a Biennal 2016

kongjian yu

In the urban heart of Jinhua, located where two rivers merge, one last piece of natural riparian wetland (named Yanweizhou) remains undeveloped. The rivers divided the densely populated communities in the region. As a result of this inaccessibility, the cultural facilities, including the opera house were underutilized. The wetland was fragmented or destroyed by sand quarries. High concrete flood walls have been built, or were planned to be built.
The design makes friends with flooding by using a cut-and-fill strategy to balance earthwork and by creating a water-resilient terraced river embankment that is covered with flood adapted native vegetation. Floodable pedestrian paths and pavilions are integrated with the planting terraces, which will be closed to the public during the short period of flooding. The terraces will also remediate and filtrate the storm water from the pavement above. The spatial organization and design forms establish an extensive permeable paved area for a large audience during the events at the opera house. While the forms and the inclusion of alcoves create places for the individuals and small groups.
The project is a proven success. The park is used by thousands daily. The water adaptive solution demonstrated in this project has now been replicated in the ecological restoration projects of other rivers in Jinhua. It is widely celebrated as a model Sponge City project and was named as The Landscape of the Year 2015 at The World Architecture Festiva.
