Kernrechtsfrage
Whether the boundary tree alley lacked a sufficient legal basis and constituted an unlawful interference with property rights.
Extrahierter Entscheid
The interference was minor, so a basis in ordinance-level law sufficed; the plan and § 1 ABauV provided a sufficient legal basis.
Extrahierte Begründung
The trees affected only a small strip of land, stood before the building line, and did not materially impair use. For minor interferences, a material legal basis is enough, and § 1 ABauV expressly allows access plans to regulate street-space design and planting.
