According to Section 3 (1) No. 6 of the German Spatial Planning Act (ROG), spatially significant plans and measures are plans, projects and other measures that take up space or influence the spatial development or function of an area.
Pursuant to Section 21 (1) of the Thuringian State Planning Act (ThürLPlG), spatially significant plans and measures must be coordinated with each other and with the requirements of spatial planning in a special procedure (spatial planning procedure).
The regional planning procedure determines whether spatially significant plans and measures are consistent with the requirements of regional planning and how spatially significant plans and measures can be coordinated or implemented from the point of view of regional planning (spatial impact assessment).
Pursuant to Section 22 (1) ThürLPlG, the spatial planning procedure can be initiated ex officio or at the request of the public or other entity responsible for a project. There is no legal entitlement to its implementation.
Pursuant to Section 22 (9), the result of the spatial impact assessment procedure must be taken into account by the public authorities in spatially significant plans and measures and in approvals, plan approvals or other official decisions on the permissibility of the project in accordance with Section 4 (2), (4) and (5) ROG.
