Dataset Direct Download Service (WFS): Restricted area of a PPRT on the Meuse department

For PPRTs, the environmental code defines a single category of zones for zones (L515-15 et seq.): areas at risk. Unlike natural RPPs, PPRTs never have restricted areas that are not directly exposed to risk. Depending on the hazard level, each TRPP area is subject to an enforceable settlement. The PPRT regulations generally distinguish two types of zones: 1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction; 2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue. The instructions in the PPRT development guide add a gradation within the “red zones” and “blue zones”.针对PPRT，环境法典针对相关区域（L515-15条及后续条文）划定了单一类别的区域：风险区域。与天然RPP不同，PPRT不存在未直接暴露于风险之中的限制区域。 依据危险等级的差异，每个TRPP区域均需遵循可强制执行的管控规范。PPRT相关条例通常将区域划分为两类： 1. "建筑禁止区域"（亦称"红色区域"）：该类区域危险等级较高，核心原则为禁止开展任何建筑活动； 2. "指定区域"（亦称"蓝色区域"）：该类区域危险等级中等，相关工程需遵循适配于具体风险类型的管控要求。 PPRT编制指南中的相关说明，还在"红色区域"与"蓝色区域"内部增设了分级体系。
