Dataset Direct Download Service (WFS): Plan for the Prevention of Natural Risks of Field Movement — Regulated Area- Commune of Bobigny (93008)

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 hazards to which it is exposed;
• stakes (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）是政府开展风险预防工作的核心工具，其核心目标为管控风险区域内的开发活动。编制风险预防计划会生成一系列空间数据，并被整合为多个数据集。
同一份风险预防计划（RPP）可包含如下空间数据集：
• 涵盖各类边界的主体风险预防计划（包括研究边界、指令性规划边界、管控范围）；
• 计划获批后的限制开发区域。风险预防计划的管控规则通常会区分两类区域：一是“禁止建设区”（俗称“红色区域”），此类区域灾害等级较高，通用规则为禁止建设；二是“符合要求建设区”，亦称“蓝色区域”，此类区域涵盖灾害等级中等且建设项目需适配问题类型与区域特点的区域，以及未直接暴露于风险但仍需遵守禁令或管控规定的区域；
• 用于风险分析的灾害地图上标注的灾害区域，该地图通过与承灾体图层叠加分析生成，需明确标注每个区域所承受的灾害等级；
• 承灾体：即受灾害威胁、可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素；
• 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致险实体的地理对象进行标识。
