Dataset Direct Download Service (WFS): Restricted area of the PPRN movement of land in the commune of Saintes en Charente-Maritime

For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk.
Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three 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;
3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs.

针对自然风险防治规划（natural PPRs），《环境法典》第L562-1条明确划定了两类区域：一是风险暴露区，二是未直接面临风险，但可通过预先采取措施避免风险加剧的区域。
根据危险等级的差异，每类区域均需遵守可强制执行的管控要求。相关法规通常将区域划分为以下三类：
1. "禁止建设区"，又称"红色区域"，该区域危险等级较高，基本原则为禁止一切建设活动；
2. "限制建设区"，又称"蓝色区域"，该区域危险等级中等，建设项目需符合适配于风险类型的管控要求；
3. 未直接面临风险的区域，但该区域内的建设工程、作业项目、开发活动或农业、林业、手工业、商业及工业类农场等行为，可能加剧既有风险或引发新的风险，因此需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然风险防治规划（natural RPPs）。
