Dataset Direct Download Service (WFS): PPRN — RPP Regulated Area Flooding — BLAMONT (54077)

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.

针对天然PPR（natural PPRs），《环境法典》在条款L562-1中划定了两类区域：一是风险暴露区域，二是虽未直接面临风险但可预先采取措施避免风险加剧的区域。
根据危险等级的差异，每类区域均需遵循可强制执行的管控规定。相关法规通常将区域划分为三类：
1. 禁建区（又称"红色区域"）：此类区域危险等级较高，通用规则为禁止建设活动；
2. 管控区（又称"蓝色区域"）：此类区域危险等级中等，相关建设项目需遵循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、商业及工业类场所/农场可能加剧既有风险或引发新风险，因此需遵守相关禁令或管控要求（详见《环境法典》条款L562-1）。该类区域仅适用于天然RPPs。
