Dataset Direct Download Service (WFS): Natural Risk Prevention Plan Linear Regulated Areas (PPRN) Castres Flood — Tarn

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.

针对自然风险预防规划（PPRs），《环境法典》（L562-1条款将区域划分为两类：风险暴露区域，以及虽未直接暴露于风险但可采取措施规避风险加剧的区域。依据灾害等级的差异，每类区域均需遵循可强制执行的建设管控要求。相关法规通常将区域划分为三类：1. "禁止建设区"（又称"红色区域"）：该区域灾害等级较高，通用规则为禁止开展建设活动；2. "指定管控区"（又称"蓝色区域"）：该区域灾害等级中等，建设项目需符合适配风险类型的相关要求；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、商业或工业经营活动可能加剧风险或引发新风险的区域，需遵守相关禁止性规定或要求（详见《环境法典》L562-1条款）。该类区域的适用范围仅限定于自然风险预防规划（RPPs）。
