Dataset Direct Download Service (WFS): PPRN SAONE AVAL Restricted Areas

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.

针对自然风险预防规划（Natural Risk Prevention Plans, PPRs），法国《环境法典（Environmental Code）》第L562-1条划定了两类区域：风险暴露区域，以及虽未直接面临风险但可采取预先防控措施以避免风险加剧的区域。根据危险等级差异，每类区域均需遵循具有强制执行力的管控规则。相关法规通常将区域划分为以下三类：
1. “禁止建设区”（俗称“红色区域”）：该区域危险等级较高，核心管控准则为禁止开展建设活动；
2. “限制建设区”（亦称“蓝色区域”）：该区域危险等级为中等，相关项目需遵守适配问题类型的管控要求；
3. 虽未直接暴露于风险之中，但建设、工程、开发活动或农业、林业、手工业、商业及工业设施可能加剧既有风险或引发新风险的区域，此类区域需遵守禁止性规定或专项管控要求（参见法国《环境法典》第L562-1条）。
后一类区域仅适用于自然RPPs。
