The topic of flood protection for the districts of johannisthal and au was the focus of tuesday evening’s council meeting. It was about the awarding of the work for the building ground investigations.
Before the decision was made, matthias kohler of the kohler office in bad steben presented the preliminary plans. Accordingly, flood protection in johannisthal is to be increased by channeling the floodwater over the rodach river. Among other things, this would require an installation structure and piping, kohler explained. The outflow in the floodplain is to be throttled so that less water flows through johannisthal. The rest of the water was cut off via a pipe and led into the river rodach. The railroad culvert is also to be used for this. Kohler explained that they had tried to approach public areas during the planning phase.
In au, kohler explained, the flood protection dike designed as a ring dike is sufficiently high. It is now a question of proposals as to how this dike could be strengthened. There is a need for action along the two. Here the structural condition must be analyzed. In addition, it must be explored by how many meters the dike must be raised. If it turns out that the dike is capable of carrying current, it would be possible to seal the corresponding area. It would also be possible to install a sheet pile wall in the ground.
