Kernrechtsfrage
Whether the development plan's departures from the base zoning rules were permissible, especially the bonus in utilization and the allowance of apartment buildings in zone W2a.
Extrahierter Entscheid
A development plan may deviate from the zoning plan, including by granting a utilization bonus, but only within narrow limits and not so far as to undermine the zoning regime; here the departures were excessive.
Extrahierte Begründung
The court held that special building planning must remain oriented to the base zoning and may only depart to the extent justified by an objective planning purpose. In this case, the concentration of utilization, increase in height and length, allowance of apartment buildings, and roof-form changes went beyond what was compatible with the W2a zone and unacceptably shifted the zoning boundary in substance.
