DDT 48 — FLOOD RISK PREVENTION PLAN FOR THE COMMUNE OF CANOURGUE

The COVADIS data standard for risk prevention plans includes all the technical and organisational specifications for the digital storage of geographical data represented in the risk prevention plans (RPPs). The major risks consist of the eight main natural hazards foreseeable in the national territory: floods, earthquakes, volcanic eruptions, terrain 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 (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. 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 RPP is the responsibility 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 translates into a geographical delimitation of the territory concerned by the risk. This delimitation defines areas in which specific regulations apply. These regulations are easement and impose requirements varying according to the hazard level to which the area is exposed. The areas are represented on a zoning plan that fully covers the 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 intensity levels of each hazard considered in the risk prevention plan. • The issues identified during the preparation 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 process the different types of risk prevention plan (natural risk prevention plans PPRN, technological risk prevention plans PPRT) This data standard does not consist of a complete modelling of a risk prevention plan dossier. The scope of this document is limited to geographical data in the RPPs, whether regulatory or not. Nor is the PPR standard intended to standardise knowledge of hazards. The challenge is to have a description for a homogeneous storage of the geographical data of the RPPs, since these data are of interest to several professions within the ministries responsible for agriculture, on the one hand, and ecology, and on the other hand, sustainable development.用于风险预防计划的COVADIS数据标准，涵盖了风险预防计划（Risk Prevention Plans，以下简称RPPs）中地理数据数字化存储所需的全部技术与组织规范。本国境内可预见的主要风险包含8类自然灾害与4类技术灾害：8类自然灾害为洪涝、地震、火山喷发、地形变动、海岸灾害、雪崩、森林火灾、气旋与风暴；4类技术灾害分别为核风险、工业风险、危险货物运输风险以及溃坝风险。 风险预防计划（Risk Prevention Plans，下文简称PPR）由1995年2月2日《加强环境保护法案》确立。PPR工具属于1987年7月22日《民用安全组织、森林防火与重大风险预防法案》的规制范畴。RPP的编制主体为国家，最终审定由行政长官完成。 无论是自然风险、技术风险还是多风险复合型的风险预防计划，均具备共通架构，其内容包含三类信息： • 规制性制图：即对受风险影响的辖区进行地理界分。该界分明确了适用特定规制条款的区域，此类规制为限制性条款，并依据区域面临的灾害等级设定差异化要求。上述区域通过全覆盖研究区域的分区制图进行可视化呈现。 • 风险源灾害信息：收录于灾害文档中，此类文档可嵌入编制报告或作为RPP附件。此类文档用于绘制风险预防计划中所考量的各类灾害的不同强度等级分布图。 • 编制过程中识别出的问题：可通过制图形式附于获批文件之后。 鉴于不同类型PPR之间的共通特性，以及提升PPR数据标准化水平的目标，COVADIS最终采用单一数据标准——该标准具备足够的通用性，可适配各类风险预防计划，包括自然风险预防计划（Natural Risk Prevention Plans，缩写PPRN）与技术风险预防计划（Technological Risk Prevention Plans，缩写PPRT）。 本数据标准并非对风险预防计划档案的完整建模，其适用范围仅涵盖RPPs中的地理数据，无论此类数据是否具备规制属性。同时，PPR标准亦并非旨在统一灾害相关认知。其核心目标在于为RPPs的地理数据提供统一描述，以实现同质化存储——此类数据同时受到农业、生态与可持续发展相关部委内多个专业领域的关注。
