Dataset Direct Download Service (WFS): Plan for Prevention of Natural Land Movement Risks — Regulatory Area — Coubron Commune (93015)

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，其核心目标为管控风险区域内的开发活动。编制风险预防计划将生成一系列空间数据，并整合为多个数据集。
同一RPP可涵盖以下空间数据集：
• 主风险预防计划边界数据集：包含研究边界、法定规划边界与管控范围；
• 获批后计划管控限制区域数据集：RPP管控规则通常划分为三类区域：其一为“建设禁建区”（又称“红色区域”），此类区域灾害等级较高，通用管控要求为禁止建设；其二为“合规适配管控区”（又称“蓝色区域”），此类区域灾害等级为中等，开发项目需根据具体问题类型适配相应管控要求；其三为未直接受风险影响，但仍受禁令或规划约束的区域；
• 灾害风险区划数据集：基于风险分析绘制的灾害分布图，通过与承灾体要素叠加分析划定，需明确各区域所承受的灾害风险等级；
• 承灾体数据集：指受灾害威胁、可能遭受影响或损失的人员、资产、活动、文化或环境遗产元素等对象；
• 风险源数据集：即通过自身存在构成潜在风险的实体对象。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。
