The EPTB’s approach to assisting municipalities to lay flood benchmarks, is part of the union’s missions to provide an animation and coordination role with basin communities on flood risk. The purpose of this service is to improve risk awareness and to enhance flood markers from a pedagogical point of view to raise awareness among the general public. The service provider will intervene on the entire perimeter of the PAPI and in partnership with the municipalities, to define strategic places to lay flood markers. It will carry out the topographic surveys and draw up flood reference plans which will be given to the municipalities.
