Plan for the Prevention of Natural Risks (PPRN) of the Loire upstream in the Loire-Atlantique

The Loire Amont PPRI was approved on March 12, 2001. It concerns the municipalities of Ancenis, Anetz, Basse-Goulaine, Haute-Goulaine — La Chapelle-Basse-Mer, Le Cellier, Le Fresne-sur-Loire, Mauves-sur-Loire, Montrelais, Oudon, Saint-Géréon, Saint-Herblon, Saint-Julien-de-Concelles, Sainte-Luce-sur-Loire, Thouaré-sur-Loire, Varades. The PPRI is a regulatory document designed to improve the safety of people and property from the risks of floods. It aims, as a matter of priority, not to exacerbate risks and to reduce vulnerability on perimeters; it covers, both from the point of view of future urbanisation and the construction methods and uses of the territory. __Origin__ This document was drawn up on the basis of atlases of flood zones notified to the municipalities concerned in 1996 and based on the flood of 1910 according to a scenario of rupture of the liftings. __Partner organisations__ DDTM Loire-Atlantique __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-ldd-14a8227e-dc87-4201-8da9-147e485668ac) * [COVADIS data standard: Risk Prevention Plan PPRN PPRT](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?lot=Plan-de-prevention-des-risques-PPRN-PPRT) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/d6db7f43d4c638144b053181b4ffd1224bb46d0b)
