Kernrechtsfrage
Whether a noise barrier had to be ordered on the appellant's parcel despite the relief request.
Extrahierter Entscheid
No; the barrier would be disproportionately costly because the cost-benefit ratio of 185 far exceeded the statutory threshold, and no case-specific exception was shown.
Extrahierte Begründung
Under Art. 7(3)(a) LBCF and Art. 20(1) OBCF, measures are disproportionate when the RCU exceeds 80. The appellant's health concerns were insufficient and not proven to result from the lack of protection.
