Regulated areas of the natural risk prevention plan of the municipality of TARASCON-SUR-ARIEGE

The regulated zoning of the Natural Hazard Prevention Plan (PPRN) is digitised in accordance with the national requirements of COVADIS. 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.自然风险预防规划（Natural Hazard Prevention Plan，PPRN）的法定管控分区已依据COVADIS的国家相关规范完成数字化转换。针对自然风险预防规划场景，《环境法典（Environmental Code）》第L562-1条划定了两类分区：风险直接影响区域，以及虽未直接面临风险但可采取措施避免风险加剧的区域。 根据风险等级的不同，各分区均需遵循可强制执行的管控细则。相关法规通常将分区划分为三类： 1. 建筑禁建区（又称“红色区域”）：该区域风险等级较高，通用规则为禁止一切建设活动； 2. 合规建设区（又称“蓝色区域”）：该区域风险等级为中等，建设项目需遵循适配问题类型的专项管控要求； 3. 间接风险影响区：虽未直接面临风险，但建设工程、开发活动或农林牧渔、手工业、商业及工业经营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（详见《环境法典》第L562-1条）。该类别仅适用于自然风险预防规划（Natural RPPs）场景。
