Urban Square Adaptation: Detention

As extreme weather events intensify and exacerbate flooding in urban areas, multipurpose urban squares can be used to detain stormwater during peak flow in a developed catchment. In this sense the Enghaveparken public park in Copenhagen adapts to dry – wet conditions and is capable to store 24,000 cubic meters of water before discharging at a controlled rate to the surrounding stormwater infrastructure.


The beauty of the Enghaveparken park, designed by the consulting group of COWI, TREDJE NATUR and Platant, is that it also provides a pleasant gathering space for recreation and other uses during dry conditions.


The initiative results as an adaptation strategy led by the city, to decentralize stormwater tools and multipurpose detention zones to help the city manage peak flows during severe storms.


When the existing stormwater infrastructure is unable to drain and convey away this peak, other more innovative urban strategies are required. Enter water sensitive urban design to transform a large amphitheater /public space into a detention basin, with clear benefits, among them educating the public of global warming and its effects on the hydrologic cycle.
