Sponge City

Blue Green Infrastructure
Sponge city concepts for healthy urban green spaces

The consequences of climate change – heavy rainfall events, heatwaves and droughts – pose major challenges for urban areas in particular, and require new urban adaptation measures. There is an urgent need for innovative greening concepts on the one hand, and integrated rainwater management on the other hand.

Instead of draining rainwater through sewer systems, the valuable resource of water needs to be stored on site with the help of blue-green infrastructures, and fed back into the urban water cycle. Together with urban planners and landscaping experts, ACO develops and realises practical solutions for your sponge city. Be inspired by our innovative concepts.

City Streets

City Streets

Our cities are criss-crossed by major traffic routes. Roads take up a large part of the area and, following the model of the carfriendly city, are still primarily designed for motorised vehicles. The high levels of traffic have a negative impact on people, nature and infrastructure.

Public Squares

Public squares

The heart of urban life beats in the puplic squares of city centers and neighbourhoods. Squares form hubs in the urban frabric and offer a wide range of design and use options- from weekly markets and catering facilities to event spaces and green-blue oases of tranquillity.

Urban Squares

Urban quarters

Cities have always attracted people from different backgrounds and cultures. This is where new ideas and trends are born. However, as centres of economic activity, cities also cause environmental pollution such as air pullution, noise and CO2 emissions.
