N_ZONE_REG_PPRN_20140557_S_032

Regulatory zoning of the PPRN flooding of the commune of Saint-Avit-Frandat 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.热尔省圣阿维-弗朗达尔市镇的自然风险防治规划（PPRN）洪水防控监管区划。 针对洪水风险防治规划（PPRI），法国《环境法典》第L562-1条将区划划分为两类：受风险直接影响区域，以及虽未直接面临风险但可通过预先采取措施避免风险加剧的区域。依据危险等级的不同，每类区域均需遵守可强制执行的建设管控规则。 相关法规通常将区划分为三类： 1. "禁止建设区"，又称"红色区域"：此类区域危险等级较高，原则上禁止任何建设活动； 2. "管控建设区"，又称"蓝色区域"：此类区域危险等级中等，相关工程建设需符合适配问题类型的管控要求； 3. 虽未直接面临风险，但各类建设、工程、开发活动或农业、林业、手工业、商业及工业场所可能加剧既有风险或引发新风险的区域：该类区域需遵守相关禁止或管控要求（参见法国《环境法典》第L562-1条）。此类区划仅适用于天然RPPs。
