Map visualisation service (WMS) of the dataset: Arthaz-Pont-Notre-Dame Natural Risk Prevention Plan (Haute-Savoie) — approved on 19/11/2001

The COVADIS Data Standard on Risk Prevention Plans includes all technical and organisational specifications for the digital storage of geographical data represented in the Risk Prevention Plans (RPPs). Major risks include the eight foreseeable main natural hazards in the national territory: floods, earthquakes, volcanic eruptions, field movements, coastal hazards, avalanches, forest fires, cyclones and storms, and four technological risks: nuclear risk, industrial risk, risk of transport of hazardous materials and risk of dam failure. The Risk Prevention Plans (RPPs) were established by the Law of 2 February 1995 on the strengthening of environmental protection. The PPR tool is part of the law of 22 July 1987 on the organisation 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 easement value and impose requirements varying according to the level of hazard to which the area is exposed. The areas are represented on a zoning plan that fully covers the study area. • The hazards causing the risk are included in hazard documents that can be inserted in the submission report or annexed to the RPP. These documents are used to map the different levels of intensity of each hazard considered in the risk prevention plan. • The issues identified during the development of the RPP 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 address 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 non-regulatory. The PPR standard is also not intended to standardise the knowledge of hazards. The challenge is to have a description for a homogeneous storage of the geographical data of the PPRs because these data concern several occupations within the ministries responsible for agriculture, on the one hand, and ecology, and sustainable development, on the other.
