Kernrechtsfrage
Whether there was a sufficient legal basis for charging the planning-study costs to the landowner.
Extrahierter Entscheid
Yes. The cantonal and communal planning rules, read together, provided a sufficient basis for passing on the study costs as planning costs.
Extrahierte Begründung
Although the statute mentions quartier planning, the study and resulting concept were directly linked to the required development concept and later detailed plan in the core zone; the cantonal interpretation was not arbitrary.
