Table containing all restricted zones of the Canche PPRN

Risk Prevention Plans (RPPs) are the key instrument for risk prevention. Their objective is to control development in risk-exposed areas.L' development of a risk prevention plan generates a series of geographical data organised into several datasets. This dataset describes the restricted areas of the plan once approved. PPR regulations generally distinguish between “zones d' prohibition to build”, so-called “red zones”, where the level of ' hazard is strong and the general rule is the “prohibition of construction”; the “prescription areas”, known as “blue zones” where the level of #x27; hazard is average and the projects are subject to requirements adapted to the type of #x27; stakes and areas not directly exposed to risks but subject to prohibitions or prescriptions __Origin__ Geometric modelling depends on the type of l' challenge and its modeling in the data source or geographical repository from which it comes. A stake is usually represented by a polygon, a polyline, or a point with a spatial resolution sufficient to appreciate s' it is concerned by one or more zones of #x27;aira. __Partner organisations__ DDTM Pas-de-Calais __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-b3eac7fe-e24d-48b4-aa96-d844c1b6adba) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/391c45f2b03ec2028b8bbb39968a6ac38e492352)
