Map Viewing Service (WMS) of the dataset: Herblay PPRN-MT (Regulated Areas)

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. This dataset describes the 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 the general rule is the construction ban; ‘areas subject to requirements’, so-called ‘blue zones’ where the hazard level is medium and the projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions

风险预防计划（Risk Prevention Plans, RPPs）是政府开展风险防控的核心工具，其核心目标为管控风险区域内的开发活动。
制定风险预防计划会生成一系列空间数据（spatial data），并将其整合为多个数据集。本数据集描述的是该计划获批后划定的限制开发区域。风险预防计划的相关监管规则通常会区分以下区域：一是“禁止建设区”，即俗称的“红色区域”，该区域危险等级较高，普遍实行建设禁令；二是“受规制区域”，即俗称的“蓝色区域”，该区域危险等级为中等，项目需遵循适配问题类型的管控要求；此外还包括未直接暴露于风险之中，但仍需遵守禁令或管控规定的区域。
