Map Viewing Service (WMS) of the dataset: Natural Risk Prevention Plan (NRPP) Restricted Areas Withdrawal Swelling of Argile — 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.针对自然风险防护区（PPRs），《环境法典》（L562-1条款）划定了两类基础区域：一是直接暴露于风险中的区域，二是未直接面临风险但可采取预判措施以规避风险加剧的区域。根据危险等级的不同，每类区域均需遵循可强制执行的处置规则。相关法规通常将区域进一步划分为三类：1. “禁止建设区”（又称“红色区域”）：该区域危险等级较高，通用规则为禁止一切建设活动；2. “规划管控区”（又称“蓝色区域”）：该区域危险等级为中等，相关项目需遵循适配问题类型的管控要求；3. 未直接面临风险，但各类建设、工程、开发活动或农场，以及农业、林业、手工业、商业或工业相关活动可能加剧既有风险或引发新风险的区域，需遵循相关禁止或管控要求（参见《环境法典》L562-1条款）。此类区域仅适用于自然风险防护区（RPPs）。
