N_ZONE_REG_PPRN_20140543_S_032

Regulatory zoning of the PPRN flooding of the commune of Lalanne in the department of Gers. For PPRIs, 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 two 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.本数据集涵盖热尔省拉朗市镇自然风险预防规划（PPRN）的洪水管控区划内容。针对洪水风险预防规划（PPRI），《环境法典》（Environmental Code）在L562-1条款中明确划定两类区域：风险暴露区域，以及未直接承受风险但可采取措施避免加剧风险的区域。依据危险等级差异，每类区域均需遵循可强制执行的建设管控规则。该管控规则通常区分三类区域：1. 「禁止建设区」（又称「红色区域」）：危险等级较高，通用规则为禁止一切建设活动；2. 「规定建设区」（又称「蓝色区域」）：危险等级中等，建设项目需适配该类风险问题的专属管控要求；3. 未直接面临风险，但建设、工程、开发活动或农业、林业、手工业、商业、工业相关经营设施可能加剧既有风险或引发新风险的区域，需遵守相关禁止性规定或管控要求（参见《环境法典》L562-1条）。该类别的适用范围仅限定于天然RPPs。
