Map Viewing Service (WMS) of the dataset: PPRT SDPN (Regulated Area)

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”, so-called “red areas”, 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，依据法国环境法典L515-15及后续条款，相关区域被统一划定为单一类别：风险区域。与天然RPPTs不同，PPRT不会设置未直接受风险波及的限制区域。依据危害等级，每个TRPP区域均需遵循可强制执行的处置规范。PPRT相关法规通常将区域划分为两类：其一为"建筑禁止区域"，即俗称的"红色区域"，该区域危害等级为中等，相关建设项目需适配问题类型落实合规要求。PPRT编制指南中的操作指引，进一步在"红色区域"与"蓝色区域"内部增设了分级划分标准。
