Dataset Direct Download Service (WFS): Regulatory zoning of the natural flood risk prevention plan — PPRi — Val de la Vrille — Nièvre (58)

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PPR（Natural PPRs），《环境法典（Environmental Code）》在条款L562-1中划定了两类区域：风险暴露区域，以及虽未直接面临风险但可预先采取措施以避免风险加剧的区域。
根据危险等级的不同，每类区域均需遵循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. 禁止建设区域，俗称“红区（red areas）”，该区域危险等级较高，基本原则为禁止一切建设活动；
2. 规定管控区域，俗称“蓝区（blue zones）”，该区域危险等级中等，相关项目需遵守适配具体风险类型的管控要求；
3. 非直接风险暴露区域：此类区域虽未直接面临风险，但各类建设、工程、开发活动或农业、林业、手工业、商业及工业经营场所可能加剧既有风险或引发新的风险，因此需遵守相关禁令或管控要求（详见《环境法典》条款L562-1）。此类区域仅适用于自然RPP（Natural RPPs）。
