The municipality has invested much in restoring the original canal structure, which in the 1970s was partly removed in order to create space for grey infrastructure (roads, a planned motorway that eventually was not built, offices etc.). To date, the municipality is planning a large-scale transformation of a former industrial area of over 11 km along the Merwede and the Amsterdam-Rhine Canals close to the city centre into a healthy and sustainable residential area for 6,000 – 15,000 new residents (the so-called city Island). As key challenges the municipality identified intensified heat stress and flood risks due to climate change. The existing and planned green-blue infrastructure of the area facilitate high-density building and measures for climate adaptation. The direct connections with valuable natural landscapes surrounding the city enable the development of local ecosystems and biodiversity. The green-blue infrastructure will also serve as nature-based solutions facilitate sports, recreation, social cohesion, biodiversity, air quality, reduction in noise, water cleaning, cooling, and (temporal) water storage.
