Since November 2019, the Structural and Approval Directorate (SGD) Nord, Regional Office for Water Management, Waste Management and Soil Protection Trier has been continuing the construction work to upgrade the approximately 1.5 km long flood protection facility in Trier between the youth hostel and the access to the RATIO shopping centre. The groundbreaking ceremony took place on 11 November in the presence of Ulrike Höfken, Minister for the Environment, Energy, Food and Forestry of the state of Rhineland-Palatinate.

The city of Trier is protected by dikes and the high bank on the right bank of the Moselle from flooding events with a 50-year chance of recurrence. The flood defence dike was built in the 1930s. In the 1960s, due to settlement construction on a long stretch, the hinterland was filled up to the height of the dike crown, so that a high bank is perceived in this area today.

In recent years, the SGD Nord has checked the stability and usability of the flood protection system. As a result, it had to be established that the functionality of the flood protection system is restricted by near-surface deformations of the dike and tree cover and as a result of anyimpairments of stability.

In the course of upgrading the flood protection system, the existing entertainment and dike defence routes will be expanded as continuous dike defense and cycle paths. In the area of the Tree Avenue between the youth hostel and the outdoor swimming pool Nord, a promenade is laid out as a footpath on the dike crown. In some areas, pile walls are installed in the dike to protect the existing trees and to ensure flood protection for the city of Trier.

Trees stand on the dike and embankments, with the trees between the youth hostel and the north outdoor pool being protected as a protected part of the landscape. Nevertheless, about 40 tree fellings and about 20 trees required crown cuts. The woods were examined for the presence of protected animal species. In order to improve the location conditions of the trees to be preserved, root bridges are installed in the paths. New trees will be planted along the footpath, cycle path and on the banks of the Mosel as a compensatory measure when the construction project is completed. All work is supervised by an ecological construction supervision. With this planning variant to be implemented, the variants examined in the planning have chosen the one in which the protected landscape component "Baumbestand am Moselradweg Trier" is shaped by the landscape can be completely preserved during the construction phase.
