Overview

• Roughly 120 trees are slated for the pedestrian zones, with about 30 in adjacent streets.
• The Baureferat has placed 80 mobile planters with QR codes to preview locations and collect donations.
• Each tree requires a 36-cubic-meter planting pit and careful coordination around dense utilities, access routes and monument protection.
• Officials estimate per-tree costs in the mid-to-high five figures, putting the total in the several-million-euro range.
• Planting is planned in stages from 2026, with some trees possible by late 2026 using stock from the municipal nursery, and a previous 3,500-tree program did not include the pedestrian zone.
