Kernrechtsfrage
Whether the appeal was admissible and appellants had standing
Extrahierter Entscheid
The public-law appeal was admissible; the individual neighbors and Association C. had standing, and Association B.'s standing was undisputed at least regarding the land cession affecting its property.
Extrahierte Begründung
They were directly neighboring owners or inhabitants, and the associations pursued member interests linked to site preservation; the appeal was timely against a final cantonal decision.
