Question juridique clé
Whether the lakeside pontoon required a derogation under Art. 24 LAT or was zone-conforming under Art. 22(2)(a) LAT.
Solution extraite
The pontoon was, in principle, zone-conforming because access to the lake at that location was objectively necessary and compatible with the protected lakeshore use.
Motifs extraits
For installations on lake shores subject to special cantonal protection measures, conformity depends on objective need and limited dimensions. A simple access pontoon serving navigation or bathing can fall within the normal use of the shore and thus satisfy Art. 22(2)(a) LAT.
