Dataset Direct Download Service (WFS): Regulatory zoning of the PPR field movement of the Saumurois Coteau (Saumur)

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.

针对自然风险预防计划（PPR），《环境法典》第L562-1条将区域划分为两类：风险暴露区域，以及虽未直接暴露于风险，但可通过预先采取防控措施避免加剧风险的区域。
根据风险等级的不同，每类区域均需遵循可强制执行的管控规则。该法规通常将区域划分为三类：
1. “禁止建设区域”，俗称“红色区域”：该区域风险等级较高，基本原则为禁止一切建设活动；
2. “管控区域”，俗称“蓝色区域”：该区域风险等级中等，相关项目需遵守适配问题类型的特定要求；
3. 虽未直接暴露于风险，但建设工程、开发项目或农业、林业、手工业、商业及工业性经营活动可能加剧风险或引发新风险的区域，需遵守禁止性规定或特定要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然风险预防计划（RPP）。
