Key legal question
Whether the cantonal court could impose restrictive closing hours for the youth culture center to protect neighbors from noise.
Extracted holding
Yes. Given the location near residences and the foreseeable client-related nighttime noise, the restrictive operating hours were justified under federal environmental law.
Extracted reasoning
The court held that noise from clients in the parking area and around the entrance could cause sensitive disturbance at night. In the absence of fixed exposure limits for such establishments, the authority had to assess emissions under the planning-value framework, taking into account sensitivity of the zone, ambient noise, and the public interest in the project. The cantonal court did not abuse its discretion by setting differentiated closing hours rather than allowing discotheque-like hours.
