Flood Risk Prevention Plan "Val de Gien"

All zoning and written documents of the PRIP approved on 11/12/2002.
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’, where the hazard level is high and the general rule is no-build zones; ‘prescribed zones’, known as ‘blue zones’, where 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 requirements;
- hazard zones represented on the hazard map used for risk analysis by crossing with the stakes, 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 may be characterised by a name, a reference to an external object or a geographical object locating the actual entity causing the risk.
