The ecological restoration works are on schedule, with the planned end to coincide with the Luga horticultural exhibition in 2023.

Not only that, the works are also still within budget, confirmed the mayor, who inspected the area with the Minister for the Environment on Tuesday.

The renaturation will include additional leisure options for residents and introduce new measures against flooding. The widened riverbed will help, for one, but the bridges, which are generally the narrowest points, will also be strengthened against the force of the water.

One hundred and sixty trees will have to be removed, but their roots will remain to help with renaturation, and 134 mid-sized trees will replace them. This number has not changed since the beginning of the works.

The foundations of the Saint Ulrich church and the “Wenzelsmauer” wall will be integrated into the new concept, though the details are not yet clear at the moment. Historian Robert Philippart supervises these plans for the Unesco. Even the minigolf course is set to return.

To ensure the best possible water quality, a variety of different measures are taken. Besides the “First Flush”, which captures dirty rain water from the streets and should be ready soon, the city must also ensure that toilets in the Gare and Hollerich quarters are no longer connected incorrectly.

This problem is not yet resolved and waste water still goes directly into the river.
