Kernrechtsfrage
Whether a special planning procedure was required before issuing the building permits.
Extrahierter Entscheid
No special plan was required because the project conformed to the zone and created no coordination problem that the permit procedure could not resolve.
Extrahierte Begründung
The Federal Act on Spatial Planning requires special planning mainly for non-conforming projects with significant territorial or environmental impact. Here the project lies in a duly legalized building zone, and the competent services could examine all aspects through the permit process.
