Milano – Dergano – Riqualificazione vie e piazze in zona: aprile 2021 – UrbanfileMilan is undergoing a significant transformation as it removes asphalt to combat urban heat islands and manage stormwater more effectively. This initiative, known as “depaving,” aims to convert impermeable surfaces into green spaces and permeable pavements, enhancing the city’s resilience against climate change.
Concrete Steps Towards a Greener Milan
Since 2022, Milan has depaved over 50,000 square meters of asphalt. This includes more than 20,000 square meters converted into new green areas and over 30,000 square meters replaced with permeable pavements. These efforts are part of the city’s strategy to become a “sponge city,” capable of absorbing rainwater and mitigating heat. (ansa.it)
Identifying Priority Areas
The city has identified 27 new areas for future depaving projects, adding to the 27 ongoing or planned sites. These areas were selected based on a “heat risk map,” which combines satellite temperature data with indicators of social vulnerability. Priority was given to locations such as schools and healthcare facilities to protect vulnerable populations like children and the elderly. (milano.repubblica.it)
A Model for Urban Transformation
One example of this transformation is Via Toce, where 1,800 square meters of asphalt were removed to create 720 square meters of green space, install permeable surfaces, and plant 35 new trees. This project demonstrates how depaving can revitalize urban areas, reduce heat, and improve air quality. (milanopost.info)
Addressing Climate Urgency
The urgency of these measures is underscored by projections indicating a 50% increase in hot days (above 35°C) and a tripling of tropical nights (above 20°C) by 2100 compared to 1984-2014. Depaving is not just an aesthetic choice but a necessary step for urban survival in the face of climate change. (ilmetropolitano.it)
Conclusion
Milan’s depaving strategy is a proactive approach to urban climate adaptation. By replacing asphalt with green spaces and permeable surfaces, the city is enhancing its resilience, improving quality of life, and setting a precedent for sustainable urban development.
