Table containing all restricted zones of Loison-sub-Lens 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. The 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” when the level of #x27; hazard is average and the projects are subject to requirements adapted to the type of #x27; issue 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 __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-76d355d8-20fc-4a12-b038-cce0ed769be7) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/f26ac94ce5e68ca3c06bed66f34014b1c8751845)
