Map Viewing Service (WMS) of the dataset: 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）是政府开展风险防控的核心工具，其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，并被划分为多个数据集。
同一套风险预防计划可包含以下空间数据集：
• 涵盖各类边界的主风险预防计划范围（含研究边界、法定规划边界、管控边界）；
• 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：其一为“禁止建设区”（又称“红色区域”），此类区域风险等级较高，通用管控规则为禁止建设；其二为“需符合特定要求的区域”（又称“蓝色区域”），此类区域包含两类子区域：一类为风险等级中等、开发项目需根据问题类型适配管控要求的区域，另一类为未直接暴露于风险但仍需遵守禁令或管控规则的区域；
• 用于风险分析的风险分布图上标注的风险区域，该类区域通过与承灾体叠加分析得到，需明确每个区域所面临的风险等级；
• 受风险威胁、可能遭受影响或损失的承灾体（含人员、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实体对象。该实体可通过名称、外部对象引用或定位实际风险源的地理对象进行标识。
