Dataset Direct Download Service (WFS): PPRN — Area regulated by Article R111-3 on the commune of Haraucourt (54250)

Pursuant to Article R.111-3 of the Urban Planning Code, these areas define the risk of subsidisation due to the dissolution of salt. Article R.111-3, approved by Prefectural Order of 19/03/1991, is PPR under Article L562-6 of the Environmental Code. 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.依据《城市规划法典》第R.111-3条之规定，前述区域划定了因盐溶作用引发的沉降风险。经1991年3月19日省长令批准的第R.111-3条，属于《环境法典》第L.562-6条所定义的风险预防规划（Preventive Protection Plan，PPR）。针对天然风险预防规划（natural PPRs），《环境法典》将其覆盖区域划分为两类（第L.562-1条）：直接受风险影响的区域，以及虽未直接暴露于风险但可采取相关措施避免风险加剧的区域。依据灾害等级，每类区域均需遵守可强制执行的开发管控要求。相关管控规则通常将区域划分为三类：1. 禁止建设区，又称‘红色区域’：此类区域灾害等级较高，通用规则为禁止建设活动；2. 规划管控区，又称‘蓝色区域’：此类区域灾害等级中等，建设项目需遵守适配该类风险类型的具体要求；3. 虽未直接暴露于风险，但各类建设、工程、开发活动或农业、林业、手工业、商业及工业经营活动可能加剧既有风险或引发新风险的区域，需遵守相关禁令或管控要求（参见《环境法典》第L.562-1条）。该类区域仅适用于天然RPPs。
