Dataset Direct Download Service (WFS): PPRN Restricted Areas RHONE AVAL — downstream sector

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PPRs（natural PPRs），《环境法典》第L562-1条将其区划分为两类：风险暴露区域，以及虽未直接面临风险但可采取相关措施以避免风险加剧的区域。依据危险等级的差异，每类区域均需遵循可强制执行的管控规范。相关法规通常将此类区划细分为三类：1. 「禁止建设区」，俗称「红色区域」，此类区域危险等级较高，基本原则为禁止任何建设活动；2. 「合规管控区」，又称「蓝色区域」，危险等级为中等，相关项目需遵循适配具体问题类型的专项合规要求；3. 虽未直接暴露于风险之中，但各类建设工程、开发活动或农林牧渔、手工业、商业及工业经营等行为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（参见《环境法典》第L562-1条）。前述第三类区划仅适用于自然RPPs（natural RPPs）。
