Underground spatial planning - Perspectives and current research in Germany

There has been a growing need over recent years for the coordination of utilizations in underground space. This study investigates rising demands on the utilization of underground space and associated conflicts related to space, responsibilities and priorities. Strategic, comprehensive, and holistic spatial planning is required to resolve these conflicts. This paper presents the current status of spatial planning regulations in Germany concerning underground space, and investigates possible planning solutions for its coordinated use. Findings of this study indicate that dedicated underground spatial planning should replace the common procedures towards designating exclusive areas for certain purposes in order to ensure the sustainable use of underground space.
