On Sunday June 5, around 11 am, a torrent of mud rushed down an isolated street in Paron. Broken doors, destroyed gardens, a dozen houses damaged. This is the second time in eight months that a phenomenon of this type has occurred in the town. According to the mayor, Jean-Luc Givord, this phenomenon could be explained by the presence of a sunflower crop upstream from the village.
The Pentecost weekend storm will have left its mark on the Yonne department. According to the mayor of Paron (Yonne), the mudslides that occurred on rue Pasteur last Sunday could be explained by multiple factors.
First of all, the exceptional intensity of Sunday’s rainfall: “60 millimeters of rain fell in the space of just 30 minutes, it is a level of precipitation that can be found in the Var, but with us it is out of the ordinary.”
The mayor also adds that at the time of the landslides, the ground was badly damaged. It hadn’t rained on the Senonais in more than two months. According to him, the soils could not absorb so much water in such a short time.
Last September, the inhabitants of rue Pasteur had already been victims of floods. But according to the mayor of the town, this phenomenon was unprecedented until now: “I’ve been in the city for 40 years and I’ve never experienced this before” admits Jean-Luc Givord.
When our team of journalists met with the affected neighbors on Monday morning, they informed us of the presence of two farm fields upstream of the street. Indeed, the avalanches descend along a small path that leads to the top of a hill, where there are crops of wheat and sunflowers.
According to the mayor, the sunflower harvest -administratively located in the municipality of Gron- would not have been carried out according to the typology of the land: “The plantations have the purpose of retaining water, but if you plant corn or sunflower on a slope, it cannot work”.
Even if Jean-Luc Givord has his personal opinion, he doesn’t want to name a culprit. The second round could be explained by many other factors such as. This could be, for example, the consequence of recent work on the South de Sens diversion. But at the moment, according to the elected official, it is impossible to pinpoint the cause of the landslides.
Given the magnitude of the damage, the municipality of Paron wishes to provide a lasting response so that this phenomenon does not happen again. A meeting will also be organized on Friday June 10 with the presence of the mayors of the intercommunals, the peasants and a person in charge of sanitation.
The idea initially would be to install cummerbunds – Editor’s Note: Wooden Dams – to cut off the path of the water and prevent it from flowing down the small path that leads to rue Pasteur. But this solution would only be effective temporarily.
The mayor of Paron wants to go even further by installing water retention ponds. Jean-Luc Givord acknowledges that the project is ambitious, but that these developments will be necessary to protect rue Pasteur and its inhabitants in the future.
