Kernrechtsfrage
Whether the administrative appeal was admissible against the protection plan under federal law and the alluvial zones ordinance.
Extrahierter Entscheid
The administrative appeal was inadmissible because the dispute concerned a cantonal land-use plan and federal environmental law was not directly at issue; the parcel was not classified as an alluvial buffer zone.
Extrahierte Begründung
The court held that only public-law appeal was generally open for zoning plans. Administrative appeal is possible only when federal environmental law is applied, which was not the case here: the parcel’s protected status was based on cantonal planning and mere proximity to the alluvial zone, not on delimitation of the alluvial object or its buffer zone.
