Following the withdrawal of the US Armed Forces from Griesheim, a former military site in the southeast of the town – previously used as an airfield and for housing – has become vacant. After the area was acquired by the Griesheim Urban Development Society (Stadtentwicklungsgesellschaft Griesheim, SEGG), a cooperative urban design competition was held for invited participants in 2020, and the revised winning entry then formed the basis of the “Griesheimer Anger” land-use plan drawn up by AS+P. The aim: to repurpose the space to create urgently needed housing and green and open spaces, as well as a kindergarten. Due to the occurrence of protected flora and fauna species, woodland within the relevant area, and the location of the site directly adjacent to a bird sanctuary and an SAC as well as nature and landscape conservation reserves, plans must meet specific species and nature conservation requirements. AS+P is also coordinating other specialist issues, including transportation capacity studies, a mobility concept, traffic and commercial noise emissions, an energy concept, climate and air pollutants, and rainwater drainage. During the planning process, the interests of several neighboring in-process land-use plans also need to be taken into account through consultation. The draft land-use plan went on public display in fall 2023. The development plan was adopted as a statute in July 2025. Since the aims and purposes of the statutory local authority planning did not comply with all the regional planning specifications for the area to be developed, a procedure to obtain permission to depart from the latter successfully applied for in 2022. The application documents were prepared and coordinated by AS+P in line with the requirements of the Darmstadt Regional Council.
