Questão jurídica principal
Whether the cantonal court arbitrarily refused a variance from the 30 m river setback under Art. 15 LEaux.
Decisão extraída
The cantonal court's strict reading of Art. 15 LEaux was not arbitrary; the planned buildings were not constructions of general interest, not location-bound by destination, and not constructions in relation to the river.
Fundamentação extraída
Even if the riverside public promenade and vehicle-free layout served a public interest, the main purpose was residential buildings. That interest did not satisfy the statutory exceptions, and the court's literal, protective interpretation remained consistent with the purpose of river protection.
