Question 24014 — natural disasters

Summary

Mrs Marie-Pierre Rixain alerts the Minister of Territorial Cohesion and Relations with Local Authorities about the floods which regularly affect the Essonne territory. In June 2019, violent storms hit the northwest of Essonne, creating significant flooding which, among other things, affected the town of Forges-les-Bains and the hamlet of La Brosse in Janvry. Many roads were closed, including the route de Gometz and rue de la Gruerie, an axis which connects the Gif plateau to the valley. On rue de la Gruerie, municipal agents placed logs to limit mudslides. In Longjumeau, 2,000 homes were without electricity for two hours. The rising water also affected the hospital center where certain premises were flooded, two operating rooms had to be closed during the night from Monday to Tuesday, which led to cancel some of the morning's non-urgent interventions. Several municipalities, like Pecqueuse, have announced that they have taken steps to have the state of natural disaster recognized, a state which had already been declared in 2018 for the municipalities of Gometz-le-Châtel, Longjumeau, Saulx-les-Chartreux, Villebon-sur-Yvette, Briis-sous-Forges, Bures-sur-Yvette, Limours. Essonne is particularly affected by the risk of flooding since 80% of Essonne municipalities are subject to it. This is the department's major natural risk: floods are estimated to occur in 30 years for Orge, 50 years for Yvette, and 100 years for Yerres. Four types of floods can occur in the Essonne territory: floods by runoff, due to excessive waterproofing of the watersheds, floods by overflow caused by the proximity of infrastructures and watercourses, the overflowing of lowland rivers, due to heavy precipitation (or long winter rains), and the overflowing floods of the Seine, with an occurrence of around 35 years. In view of this data, she questions him about the forecasting and anticipation systems for floods which could be put in place in order to better contain the consequences of these events. natural disasters that are devastating for both the population and the communities.
