Dataset Direct Download Service (WFS): Natural Risk Prevention Plan “ground movements” — Regulatory Area — Gagny Municipality (93032)

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）是政府用于风险预防的核心工具，其核心目标为管控风险区域内的开发活动。编制一份风险预防计划将生成一系列空间数据，并将其归类为多个数据集。 同一份风险预防计划可包含以下空间数据集： • 涵盖各类边界的核心风险预防计划（研究边界、法定适用边界、监管范围）； • 计划获批后的受限管控区域。风险预防计划的监管规则通常会区分三类管控空间：其一为‘禁止建设区’（俗称‘红色区域’），此类区域灾害等级较高，普遍执行建设禁令；其二为‘受约束管控区’（俗称‘蓝色区域’），该区域灾害等级为中等，项目需根据具体问题类型适配相应管控要求；其三为未直接面临风险但仍需遵守禁令或管控规定的区域； • 灾害分布图所标注的灾害区域，此类分布图通过与承灾体叠加开展风险分析，并明确各区域所承受的灾害等级； • 承灾体：指受灾害威胁、可能被波及或造成损害的对象，包括人员、财产、各类活动、文化或环境遗产元素； • 风险源：即现实中因其存在而构成潜在风险的实体。该实体可通过名称、外部对象引用或用于定位致险实体的地理对象进行标识。
