Dataset Direct Download Service (WFS): Regulated area of the PPRMT of Villaines la Carelle in Sarthe.

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 areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and 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, crafts, 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区（natural PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区，以及虽未直接面临风险但需采取预判措施以避免风险加剧的区域。依据危害等级的差异，每类区域均需遵守可强制执行的建设管控规则。该法规通常区分三类具体区域：
1. “禁止建设区”（俗称“红区”）：该区域危害等级较高，基本原则为全面禁止建设活动；
2. “合规管控区”（亦称“蓝区”）：该区域危害等级为中等，相关项目需遵守适配问题类型的专项合规要求；
3. 虽未直接面临风险，但建设工程、开发活动或农、林、手工业、商业及工业业态可能加剧既有风险或引发新风险的区域：此类区域需遵守相关禁令或合规要求（参照《环境法典》第L562-1条）。
后一类区域仅适用于自然RPP区（natural RPPs）。
