Tartas Natural Risk Prevention Plan (PPRN) – Landes (40)

The COVADIS data standard for risk prevention plans includes all technical and organisational specifications for the digital storage of geographic data represented in the Risk Prevention Plans (RCPs). The major risks include the eight foreseeable main natural hazards on 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, the risk of transport of hazardous materials and the risk of dam breaking. The Risk Prevention Plans (RPPs) were introduced by the Act of 2 February 1995 on the strengthening of environmental protection. The PPR tool forms 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 RPP falls under the jurisdiction of the State.It is decided by the Prefect.Whether they are 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 where specific regulations apply. These regulations have servitude value and impose requirements varying according to the hazard level to which the area is exposed. The areas are represented on a zoning plan that covers the entire study area. — The hazards at the origin of the risk are contained in hazard documents which may be inserted in the presentation 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 may also be appended 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, generic enough to deal with the different types of risk prevention plans (PPRN natural risk prevention plans, PPRT technology risk prevention plans) This data standard does not consist of a complete modelling of a risk prevention plan file. The scope of this document is limited to the geographic data contained in the RPPs, regardless of whether they are regulatory in nature or not. The PPR standard is also not intended to standardise knowledge of hazards. The challenge is to have a description for a homogeneous storage of the geographical data of the PPRs because these data are of interest to several professions within the ministries in charge of agriculture, on the one hand, and ecology, and sustainable development, on the other.
