1. General information Location and description of the intervention City or FUA Berlin (FUA) Region Europe Native title of the NBS intervention Ökologische und nachhaltige Sanierung auf dem Reginhard-Schulhof Short description of the intervention The schoolyard at Reginhard Primary School in Reinickendorf faced persistent challenges, often becoming unusable due to poor drainage. After rainfall, water would pool, leaving the yard submerged and inaccessible to the 400 primary school pupils. Even in dry weather, the schoolyard was far from ideal: a lack of play equipment made it uninviting, and in summer, the area became excessively hot, offering little comfort or shade. Both children and the school community, including teaching staff and parents, voiced a strong desire for improvement. Adding to the urgency for redesign, Berliner Wasserbetriebe imposed a discharge restriction, requiring rainwater to be managed on-site. This led to a comprehensive transformation of the school grounds. Large areas were unsealed, allowing water to seep naturally into the ground. Underground seepage systems were installed to enhance drainage, and the redesign introduced green spaces, a school garden, and near-natural play and exercise areas. These changes not only resolved the flooding issue but also created a more inviting and sustainable environment for students. The focus on ecological and sustainable design improved the microclimate, providing cooler surroundings and enabling outdoor breaks filled with activity and fresh air. The redesign transformed the schoolyard into a vibrant space that meets the needs of both children and the environment. This project was funded by the Berlin Programme for Sustainable Development (BENE Umwelt) and financed by the European Regional Development Fund (ERDF).

Objectives of the intervention Objectives of the intervention Goals of the intervention To prevent flooding by installing infiltration systems. (Ref. 3) To improve the microclimate through unsealing the grounds and providing shade. (Ref. 3) To increase the greening of outdoor areas. (Ref. 3) To improve the play and recreational value of the space for children. (Ref. 3) To create areas where children can experience and learn about nature. (Ref. 3) Key Priorities Climate action (adaptation and/or mitigation) Social Justice and community Sustainability challenge(s) addressed Climate action for adaptation, resilience and mitigation (SDG 13) Climate change adaptation Green space, habitats and biodiversity (SDG 15) Green space creation and/or management Water management (SDG 6) Flood protection Stormwater and rainfall management and storage Health and well-being (SDG 3) Creation of opportunities for recreation Enabling opportunities for physical activity Social justice, cohesion and equity (SDG 10) Environmental education Climate change adaptation: What activities are implemented to realize the conservation goals and targets? Increase urban vegetation cover to reduce urban heat island effect Implement sustainable urban drainage schemes to manage stormwater Implementation activities and NBS focus Implementation activities The school yard experienced an eco-social upgrading and improvement of its rainwater management. The existing infiltration trench was renewed and enlarged, and trees, shrubs, flowering shrubs and a school garden were implemented, which constitute settings for a green classroom and spaces to encounter nature. Natural-based materials were used to construct and design play and exercise areas on the grounds. The degree of sealing was reduced. Of the total area of 2,850 square metres, 1,461 square metres were designed with water-permeable surfaces or unsealed. This corresponds to a degree of sealing of around 50% and a reduction in sealed surfaces of around 20% compared to the existing area. This measure has improved the microclimate and the groundwater recharge rate in the school playground. (Ref. 3) An important element in the nature-orientated redesign of the schoolyard was the involvement of the student parliament. Thanks to the children's' involvement, a boulder was given a new lease of life. (Ref. 4) Type of NBS project Creation of new green areas Creation of any other green urban spaces 3.

Governance and financing Governance Governance arrangements Co-governance with government and non-government actors Please specify the roles of the specific government and non-government actor groups involved in the initiative The project was financed by the regional government through the Berlin Programme for Sustainable Development (BENE Umwelt) and EU funding . The project was designed by a landscape architect and the school children participated in the implementation of the project. The school had to implement the project due to a discharge restriction imposed by the Berlin water company.
