During the winter of 2024–2025, several pieces of playground equipment were removed from the "In den Neun Morgen" playground because they were outdated. This freed up space for the installation of new playground equipment.

Children, young people, parents, and local residents were invited to a participation meeting. As the playground is relatively small, no major changes are possible. Therefore, various designs for new playground equipment were presented directly. The children and young people voted for their favorites.

• The community meeting took place on Thursday, July 11, 2024, at 5:00 p.m. at the playground.
• Construction work on the playground took place in the fall/winter of 2024/25.
• The playground has been open again since February 2025 and is ready for use.

A total of €50,000 is available for the purchase of new playground equipment under the "Child-Friendly Mainz" budget item of the Office for Youth and Family Affairs.

On July 11, 2024, the participation event took place at the playground. Employees of the Parks and Environment Department presented two different designs for new playground equipment to the children, young people, residents, and local politicians in attendance. With 5 votes to 13, the children chose a climbing tower with a slide, a rocking animal, and a sandpit. The equipment was ordered in the summer and installed in December. The playground has been open again since February 2025 and is ready for use. On April 30, the playground was officially opened by Dr. Eckart Lensch, Head of Social Affairs, Janina Steinkrüger, Head of Environmental Affairs, and the Mainz-Marienborn Local Advisory Council.
