Green light for the Alsatian space: new park for better air quality!

On April 1, 2025, the symbolic groundbreaking for the redesign of the Alsatian square took place in Wiesbaden. Mayor Gert-Uwe Mende (SPD) and Mayor Christiane Hinninger and construction and traffic director Andreas Kowol (the Greens) gave the starting signal for the important project. The aim of the project is to convert a currently used parking space into a lively park that is intended to increase the quality of life of the population and take into account the challenges of climate change.

Hinninger emphasized that the new park will not only serve as a resort of recreation, but will also significantly improve the small climate of the area. Due to the greening, a temperature reduction in summer can be expected by up to five degrees. The planned park will contain various design elements, including a fountain with a water play area, large lawns and a terrace for games and activities.

sustainable concepts and urban resilience

The expansion of the green areas is associated with a comprehensive concept for sustainability. Among other things, the resource conservation is to be used with used natural stone coverings. Mayor Mende sees this redesign a significant contribution to the quality of life in the Westend Wiesbadens. A decisive factor for the implementation of the project was the construction of a large parking garage nearby, which enables more parking spaces to be available. After the renovation, 429 parking spaces will be available in the neighborhood garage and 75 in the northern part.

In the context of the redesign, the planting of 40 climate silants trees as well as the greening with an area of ​​2200 square meters of shrubs and perennials as well as 3000 square meters of lawn. In order to optimize rainwater use, Estática built a cistern with a capacity of 200 cubic meters for the collection of rainwater.

This is in line with the unique rainwater management system of the city of Wiesbaden, which is integrated into this concept via Klarenthaler Strasse. The "sponge city concept" is intended to help store water in urban space in the long term, which is becoming increasingly important in view of the climatic changes. This innovative approach has already proven itself in other cities such as Leipzig, where similar concepts for sustainable water management have been successfully implemented.  Source 3 describes the measures for resilience compared to climate-related challenges that also play a role in Wiesbaden.

financial support and outlook

The project is financed by the urban development program "Growth and Sustainable Renewal", with grants of 660,000 euros being acquired by the federal and state governments. Overall, a sum of around 7.6 million euros is invested in the city green. The completion of the renovation is planned for autumn 2026 and will hopefully bring an improvement in the quality of life in the region, which is also promoted by the German adaptation strategy to climate change. This strategy supports measures to adapt and shows how important environmentally friendly urban development is. Source 2

With the conversion of the Alsässer Platz into a park, Wiesbaden not only shows engagement for more green spaces, but also sets a clear sign in the direction of climate adaptation and sustainable urban development. It remains to be seen how these measures will affect the urban climate and quality of life of the residents.
