Dataset Direct Download Service (WFS): Restricted area of a PPRT in Haut-Rhin

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（原文PPRT），《环境法典》（L515-15条及后续条款）将相关区域划定为单一类别，即风险区域。与自然风险预防规划（RPP，原文RPP）不同，PPRT不包含未直接暴露于风险中的受限区域。 根据危险等级的不同，每个TRPP（原文TRPP）区域均需符合具有强制执行力的管控要求。PPRT相关法规通常将区域划分为两类： 1. "禁止建设区"，亦称"红色区域"，该区域危险等级较高，通用规则为禁止开展任何建设活动； 2. "指定管控区"，亦称"蓝色区域"，该区域危险等级为中等，建设项目需遵循适配于风险类型的管控要求。 PPRT编制指南中的相关指引进一步在"红色区域"与"蓝色区域"内部增设了分级标准。
