In the spatial planning field this involves the strengthening of the higher level central spaces as healthcare centres and interconnection points for public transport services, the reinforcement of basic centres to secure primary care provision to the population in neighbouring districts and to stabilise the comprehensive coverage of the population with public service facilities and equal opportunities for access. The basic principles on which the ROP is built are sustainability, equality and gender equality. The spatial planning instruments identified are central places (concentration of development potential and reinforcement of exchanges of services between different levels of central places and their spheres of influence), function identification, threshold values, functional networks, priority areas, regional green corridors, settlement breaks. In addition there are also statements on mobility and the environment (especially the protection of open spaces and climate protection).
The purpose of Saarland's "Settlements" regional development plan is to coordinate different land use claims. These claims on the land need to be weighed up against each other with regard to their supra-local relevance and certain specific land use functions need to be secured through regional planning. To fulfil this task, Saarland's "Settlements" regional development plan defines goals and principles that relate to or have a bearing on settlement structure development. In addition to the written provisions on this subject, a graphic map of the "Settlements" regional development plan also contains provisions in graphic form. Saarland's "Settlements" regional development plan represents a state-wide spatial development plan, which is aimed at ensuring the sustainability and environmental soundness of the state's future settlement development.
