Kernrechtsfrage
Whether subdivision revived exhausted building rights for the parcel under cantonal planning law.
Extrahierter Entscheid
No. Surface already used to calculate density for the original development could not be counted again after subdivision.
Extrahierte Begründung
Density coefficients protect sufficient open space; allowing the same surface to be reused after subdivision would undermine that purpose. Exhausted building rights are not revived by later parcelling.
