Flood protection measures in Copenhagen, Denmark, are to protect citizens from future flooding caused by torrential rain. Together with two partners, COWI won an idea competition with an innovative proposal for how a park can protect a Copenhagen quarter from future flooding.
Finding room for 26,000 m3 of water in a historic and preservation-worthy park in the centre of Copenhagen was the starting point of the idea competition. Instead of leading the water away from the city quarter through underground sewers, Enghaveparken Park will in the future delay vast amounts of rainwater before leading it onwards to the port of Copenhagen.
The winning entry by architectural firm TREDJE NATUR, process consultants Platant and COWI is considered an inspiring and innovative proposal, and will contribute to renewing the Copenhagen quarter of Vesterbro. The proposal outlines how Enghaveparken can be adjusted to meet the challenges that the quarter will see in the next 100 years, in terms of flood protection and the citizens’ need to use and move around the city’s spaces.
Smart engineering respects preservation considerations
Since 1928, Enghaveparken has been a lung for the city’s inhabitants. Being preservation-worthy, the park’s overall structure with rows of trees and hedges will be preserved because the proposal makes it a priority not to disturb the park’s structure and overall appearance in any major ways. Rather the park’s spaces and functions will be updated to match future needs.
The proposal builds on old engineering skills such as constructing a wall that fences in the park and delays torrential rain like a large-scale dust pan. The wall will feature an outline of a water channel, which collects rainwater from the park and the surrounding rooftops – hinting at viaducts as we know them from ancient Rome. Digging hollows in the park, recycling the water in the park, increasing biodiversity and upgrading the public space are also keynotes in the proposal.
