Natural or technological risk prevention plans (PPRN / PPRT)
Description
Risk prevention plans (RPPs) are the government's key instrument for risk prevention. Their objective is to control development in areas at risk. The development of a risk prevention plan generates a spatial dataset organized into several datasets. The same PPR may include spatial datasets containing: - main perimeters encompassing the RPP (study perimeters, prescription perimeters, regulated perimeters); - restricted areas of the plan once approved. RPP regulations generally distinguish between "no-build zones", known as "red zones", when the hazard level is high and the general rule is no-build zones; "prescribed zones", known as "blue zones" when the hazard level is medium and projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions;- hazard zones represented on the hazard map used to analyse the risk by crossing with the issues, specifying for each zone the level of hazards to which it is exposed; - issues (people, property, activities, cultural or environmental heritage elements) threatened by a hazard and likely to be affected or damaged by it; - origins of risk, i.e. the real-world entity which, by its presence, represents a potential risk. This entity can be characterised by a name, a reference to an external object or a geographical object locating the actual entity causing the risk. https://data.georisques.fr/id/dataset/53ea528c-3803-4c48-acbb-159635d9c060
