The objective of the mission that the Seine-Saint-Denis General Council carried out in May 2012 had the dual objective of:

  • identify the causes of the extent of the damage that occurred during the April 2012 floods;
  • to study the solutions making it possible to reduce the vulnerability of the island, in particular of certain sensitive sectors and infrastructures, vis-a-vis the risk "flood".

Thus, this report proposes, in certain sectors (the 4 focus areas), improvements that are technically simple to achieve even if for some, a certain investment is necessary. Sometimes it will be necessary to carry out a complementary study using more precise data or to confirm the calculations made by a site identification in order to validate or readjust the solutions proposed.
