Summary The state ’ s flood protection strategy was expedient The flood protection measures that were implemented have proven themselves without exception. There was no damage to flood protection facilities restored after 2002 Precautions against flooding are a key building block – raising awareness behind the dikes Flood protection pays off. The damage is far greater than the investment in appropriate protective measures Accelerate the implementation of measures Strengthen private protective measures 18 Sept. 2013 June 2013 flood - ELBE FLOOD JUNE 2013 - State Chancellery Saxony-Anhalt
