Regulated zone of the Keys Natural Risk Prevention Plan (Haute-Savoie) — approved on 05/07/2019

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.针对自然风险防治规划（PPRs），《环境法典》第L562-1条将区域划分为两类：一类为风险暴露区域，另一类为未直接暴露于风险但可通过预先制定防控措施避免风险加剧的区域。依据危险等级，各区域均需遵循可强制执行的管控规则。相关法规通常将区域划分为三类： 1. 禁止建设区（又称“红色区域”）：该区域危险等级较高，通用规则为禁止一切建设行为； 2. 指定管控区（又称“蓝色区域”）：该区域危险等级为中等，建设项目需遵循适配问题类型的相关要求； 3. 非直接风险影响区域：此类区域虽未直接暴露于风险中，但各类建设工程、开发活动或农林牧渔、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，因此需遵循相关禁令或管控要求（参见《环境法典》第L562-1条）。该类区域仅适用于自然RPPs。
