Environment

Based on the results of the Elbe flood protection concept, the construction of a controlled flood polder is planned on the left bank of the river near the village of Außig. In addition to the reinforcement of existing dykes, a barrier structure and dyke in the Dahle and the neighbouring Dahle floodplain north of the village of Seydewitz is also planned. The technical planning of the flood protection system will be supplemented by extensive environmental and nature conservation planning services in order to ensure that the project can be approved in the planning approval procedure.
