Risk prevention plan PPRN field movement of Val de Creuse Val d'Anglin

The COVADIS data standard on risk prevention plans includes all technical and organisational specifications for storing spatial data represented in the risk prevention plans (RPPs) in digital format. The main risks comprise the eight main natural risks foreseeable on the national territory: floods, earthquakes, volcanic eruptions, land movements, coastal risks, avalanches, forest fires, cyclones and storms, and four technological risks: nuclear risk, industrial risk, the risk of transport of dangerous goods and the risk of dam failure.The risk prevention plans (PPR) were established by the Act of 2 February 1995 on the strengthening of environmental protection. The PPR tool is part of the law of 22 July 1987 on the organization of civil security, the protection of the forest against fire and the prevention of major risks. The development of a PPR falls within the competence of the State. It is decided by the Prefect.Whether natural, technological or multi-hazard, risk prevention plans have similarities. They contain three categories of information:• Regulatory mapping results in a geographical delimitation of the territory concerned by the risk. This delimitation defines areas in which specific regulations apply. These regulations have the value of easement and impose requirements that vary according to the level of hazard to which the area is exposed. Areas are represented on a zoning plan that fully covers the study area.• The hazards causing the risk are listed in hazard documents that can be included in the submission report or appended to the RPP. These documents are used to map the different levels of intensity of each hazard taken into account in the risk prevention plan.• The issues identified during the development of the PPR can also be annexed to the approved document in the form of maps.These similarities between the different types of PPR and the desire to achieve a good level of standardisation of PPR data have led COVADIS to opt for a single data standard, sufficiently generic to deal with the different types of risk prevention plan (PPRN natural risk prevention plans, PPRT technological risk prevention plans).This data standard does not consist of a complete modeling of a risk prevention plan file. The scope of this document is limited to the geographic data contained in the RPPs, whether regulatory or not. The PPR standard is also not intended to standardize knowledge of hazards.The challenge is to have a description for a homogeneous storage of PPR geographical data because these data concern several professions within the ministries in charge of agriculture, on the one hand, and ecology, and sustainable development, on the other hand.
