Montreal-la-Cluse PPRN (partial revision)

For natural RPPs, the Environmental Code defines two categories of areas (L562-1): risk-prone areas and areas that are not directly exposed to risks but on which measures may be provided for avoid increasing the risk. Depending on the hazard level, each area is subject to a enforceable regulation. The regulations generally distinguish three types of zones: 1- “Building prohibited areas”, so-called “red zones”, when the level of D’aléa is strong and that the general rule is the prohibition on construction; 2- “areas” subject to requirements, referred to as ‘blue zones’, where the hazard level is average and that projects are subject to requirements adapted to the type of issue; 3- Areas not directly exposed to risks, but where constructions, works, development or agricultural, forestry, artisanal, commercial or industrials could aggravate risks or cause new, submitted prohibitions or prescriptions (cf. Article L562-1 of the Environmental Code). This last category applies only to natural RPPs.针对自然风险预防规划（RPP），《环境法典》（L562-1条款）划定了两类区域：易受风险影响区域，以及未直接暴露于风险但需采取措施以避免风险加剧的区域。根据风险等级的不同，每类区域均需遵守可强制执行的监管要求。监管规则通常将区域划分为三类：1. "禁止建设区域"，即所谓的"红区"：当风险等级较高时，通用规则为禁止开展建设活动；2. "受监管要求约束的区域"，即"蓝区"：该区域风险等级为中等，相关建设项目需遵守适配问题类型的监管要求；3. 未直接暴露于风险的区域：此类区域内的建设工程、开发活动或农业、林业、手工业、商业及工业活动可能加剧既有风险或引发新的风险，因此需遵守禁止性规定或监管要求（详见《环境法典》L562-1条款）。该最后一类区域仅适用于自然RPP。
