Question juridique clé
Whether the partial zoning plan lacked sufficient normative density and thus violated planning law and constitutional requirements.
Solution extraite
The plan was sufficiently detailed: it structured exterior spaces and left only the architecturally necessary discretion for permit stage implementation.
Motifs extraits
The court agreed with the cantonal court that the regulation set the necessary principles and concretized the planning goals; it was not unacceptably vague or lacunary.
