Questione giuridica chiave
Whether the administrative appeal was admissible against the protection plan under federal law and the alluvial zones ordinance.
Decisione estratta
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.
Motivazione estratta
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.
