Map Viewing Service (WMS) of the dataset: Regulated areas of the Tarnos Natural Risk Prevention Plan (NRPP) — Landes (40)

For Natural Risk Prevention Plans (NPPs), 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.

针对自然风险防控计划（Natural Risk Prevention Plans，NPPs），《环境法典》（Environmental Code）第L562-1条定义了两类区域：风险暴露区域，以及虽未直接面临风险但可采取措施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开发建设管控规则。
该法规通常将区域划分为三类：
1. “禁止建设区域”，又称“红色区域”：此类区域危险等级较高，通用规则为禁止任何建设活动；
2. “管控区域”，又称“蓝色区域”：此类区域危险等级为中等，相关项目需遵守适配问题类型的合规要求；
3. 虽未直接暴露于风险之中，但各类建设工程、开发项目或农场、农业、林业、手工业、商业及工业活动可能加剧既有风险或引发新风险的区域，需遵守相关禁止性规定或合规要求（详见《环境法典》第L562-1条）。该第三类区域仅适用于自然风险防控计划。
