Flooding in the area

It rained last night over the Cévennes - north east of Montpellier - the equivalent of 6 months of rain in Paris... Consequently all the rivers in the area are getting much bigger all at once including le lez opposite my flat ! There has been serious flooding in the past but lately the worst has been avoided thanks to a lot of prevention works : digging ditches and artificial reservoirs.
Nevertheless if you are considering buying a property down here it's worth looking into this issue. French Help Services - www.frenchhelpservices.com -can certainly advice you. We know our area and how to get specific information.
