Questione giuridica chiave
Whether the appellants had standing to challenge the attribution of DS III to the lakeshore leisure area.
Decisione estratta
Their standing was doubtful and, in any event, the challenge failed on the merits because DS III was permissible for the planned leisure use and did not affect their own parcel.
Motivazione estratta
Their parcel already benefited from DS II; the contested designation would not restrict their own land use. The canton did not exceed its discretion under the noise ordinance.
