Key legal question
Whether the plant tubs installed for traffic calming were reviewable traffic restrictions under the SVG/SSV rules.
Extracted holding
The plant tubs were part of the road installation, not functional traffic restrictions under the SVG; the building permit for them was final and could not be reviewed in this proceeding.
Extracted reasoning
Bauliche traffic-calming works are treated as road construction measures governed by cantonal and municipal road law, even if they pursue the same goal as a traffic restriction.
