Dataset Direct Download Service (WFS): Restricted area of the PPRT of the establishment Picoty/SDLP (Sté du Dépôt de La Pallice) in the commune of La Rochelle in Charente-Maritime

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”.就PPRT而言，其环境编码为L515-15及后续条款所涵盖的各类区域定义了单一类别：风险区域。与天然RPPs不同，PPRT不存在未直接受风险波及的受限区域。 根据危险等级的不同，每个TRPP区域均需遵循可强制执行的管控要求。PPRT相关法规通常将区域划分为两类： 1. 建筑禁建区（又称"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筑活动； 2. 指定管控区（又称"蓝色区域"）：该区域危险等级中等，区内项目需遵循适配风险类型的管控要求。 PPRT编制指南中的操作细则还在"红色区域"与"蓝色区域"内部增设了分级体系。
