Architecture studio Tredje Natur is redesigning a Copenhagen neighbourhood to better handle the floods expected as climate change leads to fewer but heavier rain storms. When heavy rainfall strikes Saint Kjeld’s Kvarter, the water will be collected above ground in parks and squares to simultaneously relieve the sewer systems and create new recreational areas around the pools. A giant ring in the main square will spray out a cooling mist on hot days, while excess water will be channelled along new cycle lanes that will double as storm drains, leading to canals and out to the harbour rather than into people's basements. The architects and local government hope the scheme will become a model for green urban planning and a showcase for climate adaptation technology.
