Regulatory zoning of the Flood Risk Prevention Plan (PPRI) on the municipalities of Ollioules, Sanary sur Mer and Six Fours les Plages (Var)

The Risk Prevention Plans (P.P.R) codified in Articles L562-1 to L562-7 and R562-1 et seq. of the Environmental Code, relating to the prevention of foreseeable natural hazards, the implementation of which falls under Decree No 95-1089 of 5 October 1995, is one of the tools for the implementation of the State’s flood prevention policy, which was redefined in the Inter-Ministerial Committee of 24 January 1994. This legislative and regulatory framework was supplemented by the Law of 30 July 2003. The Plan for the Prevention of Natural Risks of Floods in the municipalities of Ollioules, Sanary sur Mer and Six Fours les Plages, linked to the presence of the Reppe River, was approved by prefectural decree of 25 March 2010. A regulation refers to prohibition and/or prescribing measures according to the classification of risks. Hazard mapping (allowing the development of regulatory zoning) was defined on the basis of mathematical modelling of 100-year flood flows carried out on a photogrammetric plane background at the scale of the 1/5000th. The hazard thus realised, a mapping of the risk followed after the crossing with the vulnerability of people and property. The postponement was based on IGN2004©EDR 25. __Origin__ The geometric modeling of ' entity at ' origin of risk depends on the type of risk, the context of the PPR, the nature of the generator and its modeling in the data source or geographical repository from which it originates.For example, a water course may be represented by a polygon or a polyline according to its size and width, an ICPE by a point (if the location of its enclosure n' is not known) or by a polygon (especially from the grey area of the PPRT).The geometry of this class d' objects is optional when: — this geometry is already carried by an object d'a geographical repository or d' an external data source, to which it is then recommended to refer to the ' help of its identifier (and thus avoid unnecessary duplication);- it does not exist because the origin of the risk cannot be precisely defined or localised (c' is the case of certain risks such as, for example, earthquakes, avalanches, sea submersions...)Nevertheless, as it is in practice rare to benefit from stable references to external objects, the geometry of l' origin of the risk will often result from the duplication of that of the #x27; object representing the #x27; origin of the risk. __Partner organisations__ DDTM Var, DDTM83/SAD/BR __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-5a0fa515-fdc6-4b56-86b2-8b95dde2b9a3) * [COVADIS data standard: Surface entity at the origin of the risk of PPRT](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ORIG_RISQ_PPRT_AAAANNNN_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/e266541700314513abf1b2e12d763008114651c0)
