2022 Cat A - Blue-green walls of Quedlinburg
The «Blue-green walls of Quedlinburg» is a complex of soft engineering solutions for managing rainfall by means of the vegetated treatment network. This network will strengthen the biodiversity and green infrastructure of Quedlinburg. Throughout the area was created multifunctional spaces for people: a parking house with a café and gardens for local residents on the roof; a park with a meandering stream to enhance biodiversity and create a natural meeting place for people (in winter the south part of the park can be used as an ice rink); rain gardens with seating next to the church in the centre of the old town to capture excess rainwater from the roofs of the surrounding buildings. Wherever possible, green roofs have been proposed.
