Plan for the Prevention of Natural Risks (PPRN) of the Sèvre Nantaise: Restricted zones, in Loire-Atlantique

Risk Prevention Plans (RPPs) are the key instrument for risk prevention. Their objective is to control development in areas at risk. The restricted zones of the Nantaise Sip PPRN delineate perimeters in which to apply the requirements of the PPRN Regulation. This PPRI (flood risk prevention plans), approved on 3 December 1998, concerns the municipalities of Boussay, CLISSON, GETIGNE, GORGES, LA HAIE-fouassiere, LE PALLET, MAISDON-SUR-SEVRE, Monnieres, NANTES, REZE, SAINT-FIACRE-SUR-MAINE, VERTOU. The PPR Regulation distinguishes between “zones d' prohibition to build”, where the level of ' hazard is strong and the general rule is ' prohibition of construction and “areas subject to requirements” when the level of #x27; hazard is average and projects are subject to requirements adapted to the type of #x27; issue. __Origin__ Elements digitised by ADASEA, when pre-applying the CAD application on the basis of a location plan filed by the farmer, and any modifications made during the course of the DDAF or ADADSEA. __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-jdd-f6261f48-531e-4c5b-8a88-057c3461694a) * [COVADIS data standard: Contracts signed for the commitment of D & D; CAD/CTE linear elements](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_CONTRAT_CAD_L) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/f2c17d872a6d8a40ff4cc6f1affb4219f3dea2e7)
