Dataset Direct Download Service (WFS): Plan for the Prevention of Natural Risks of Field Movement — Regulatory Area — Municipality of Puteaux (92062)

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，简称RPPs）是政府开展风险防控工作的核心工具，其核心目标为管控风险高发区域的开发建设活动。编制风险预防计划会生成一系列空间数据，并将其划分为多个数据集。同一份风险预防计划可包含以下类型的空间数据集：
• 涵盖各类边界的主体风险预防计划，包含研究边界、法定划定边界与管控范围；
• 计划获批后的管控区域。风险预防计划的管控规则通常会区分两类核心区域：一是“禁止建设区”（又称“红色区域”），此类区域风险等级较高，原则上禁止开展建设活动；二是“约束建设区”（又称“蓝色区域”），其中风险等级中等的区域需根据具体问题类型适配建设管控要求，此外未直接暴露于风险但仍需遵守禁令或管控要求的区域也归入此类；
• 风险分析专用风险分布图中标记的风险区域——此类区域通过与承险对象图层开展空间叠加分析生成，且需明确标注各区域所承受的风险等级；
• 承险对象（stakes）：即受风险威胁、可能遭受影响或损失的人员、财产、生产活动、文化或环境遗产要素；
• 风险源（origins of risk）：即实际存在并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。
