Risk Prevention Plan Flood “Val d’Orléans — Orlean agglomeration”

All zoning and written documents of the PPRI approved on 02/02/01.
Risk Prevention Plans (RPPs) are the key government instrument for risk prevention. Their objective is to control development in areas at risk. The development of a risk prevention plan generates a set of spatial data organised into several data sets. The same PPR may include spatial datasets containing:
— main PPR encompassing perimeters (study perimeter, prescription perimeter, regulated scope);
— restricted areas of the plan once approved. RPP regulations generally distinguish between ‘construction ban areas’, so-called ‘red areas’, where the hazard level is high and where the general rule is the construction ban; ‘areas subject to requirements’, 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 prescriptions;
— hazard areas represented on the map of hazards used for risk analysis by crossing with the stakes, specifying for each zone the level of the hazards to which it is exposed;
— issues (persons, 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, through its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object that locates the actual entity causing the risk.

风险预防计划（Risk Prevention Plans, RPPs）是政府开展风险防控的核心工具，其核心目标为管控风险区域内的各类开发活动。风险预防计划的编制将生成一套空间数据，并将其划分为多个数据集。同一PPR可包含以下类别的空间数据集：
—— 涵盖各类边界的主PPR：包括研究边界、管控边界与法定范围；
—— 计划获批后的受限管控区域。RPP的管控规则通常区分两类核心区域：一是"禁止建设区"（即所谓"红色区域"），该区域危险等级较高，原则上禁止建设；二是"约束管控区"（即"蓝色区域"），这类区域危险等级为中等，项目需根据问题类型适配专属管控要求；此外还包含未直接暴露于风险之中，但仍需遵守禁令或管控规定的区域；
—— 风险分布图上标注的风险区域：用于结合风险受体开展风险分析，并明确各区域所面临的危险等级；
—— 受危险威胁、可能遭受影响或破坏的承险对象：包括人员、财产、生产活动、文化或环境遗产要素等；
—— 风险源：即因自身存在而构成潜在风险的现实实体。该实体可通过名称、外部对象引用，或用于定位实际风险源的地理对象进行标识。
