As city complexities increases and urban structures grow multitude social interests, ecosystems, and networks meet and merge in our cities. Due to climate changes cities will frequently become more exposed to extreme weather conditions, which induce new demands of how to approach city plan- ning in the future. This project, the Sponge Line, propose a design solution that can handle water management while function as a large public space for the inhabitants in Vejle, Denmark. Manifesting the ecological qualities that are embodied in the natural sponge, as having the ability to hold, clean, and drain water, a sustainable and long-termed technical and urban solution have been implemented to absorb the stress of rising sea levels and storm floods. By questioning and challenging the already existing and conceptual term “Sponge City”, the Sponge Line becomes an specific concept that works with the social layers in the city by reading the urban context and landscape.
