Dataset Direct Download Service (WFS): PPRN — RPP Regulated Area Flood — Haroue (54252)

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PPRs（Natural PPRs），《环境法典》（Environmental Code）第L562-1条规定了两类区域：风险暴露区，以及虽未直接面临风险但可采取相关措施以避免风险加剧的区域。
根据危险等级的不同，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三类：
1. 禁止建设区（"红色区域"）：该区域危险等级较高，通用规则为严禁建设行为；
2. 限制建设区（"蓝色区域"）：该区域危险等级中等，相关工程建设需遵守适配风险类型的管控要求；
3. 虽未直接面临风险，但任何建设工程、作业项目、开发活动或农业、林业、手工业、商业及工业类经营场所均可能加剧既有风险或引发新风险的区域，该类区域需遵守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RPPs（Natural RPPs）。
