Regulated areas of the plan for the prevention of natural hazards of the municipality of VARILHES

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.

自然灾害预防规划（Natural Hazard Prevention Plan，PPRN）的合规区划已依据COVADIS的国家级规范要求完成数字化。针对自然类PPRN，《环境法典》划定了两类区划（L562-1）：风险暴露区，以及虽未直接暴露于风险但可采取措施避免风险加剧的区域。依据风险等级，每类区划均需遵循可强制执行的管控规则。相关管控规则通常将区划分为三类：1. "禁建区"，亦称"红区"：此类区域风险等级较高，通用规则为禁止建设；2. "管控区"，亦称"蓝区"：此类区域风险等级中等，建设项目需遵循适配风险类型的管控要求；3. 虽未直接暴露于风险，但建设、工程、开发活动或农场、农业、林业、手工业、商业及工业业态可能加剧既有风险或引发新风险的区域，需遵循相关禁令或管控要求（详见《环境法典》第L562-1条）。此类区划仅适用于自然类RPPs。
