Dataset Direct Download Service (WFS): Natural Risk Prevention Plan — Regulatory Area — Municipality of Saint-Cloud (92064)

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管控工具，其核心目标为管控高风险区域的开发活动。编制风险预防计划将生成一系列经分类整合的空间数据集。 同一份风险预防计划所包含的空间数据集通常涵盖以下类别： • 核心风险预防计划边界数据：涵盖研究范围、法定管控范围及规制范畴； • 获批后的计划管控区域：风险预防计划的规制条款通常区分三类区域：一是“禁止建设区”（即所谓“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“合规要求管控区”（即“蓝色区域”），此类区域灾害等级为中等，开发项目需根据问题类型适配相应合规要求；三是未直接暴露于风险但仍受禁令或规制约束的区域； • 风险区划数据：通过将风险与承险体交叉分析以开展风险评估的灾害地图中所标注的风险区域，需明确标注每一区域所面临的灾害等级； • 受险对象：指受灾害威胁、可能遭受影响或损毁的对象，包括人员、财产、各类活动、文化或环境遗产元素； • 风险源数据：指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。
