PPRN de Montluel

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.针对自然风险易感场所（Natural Risk-Prone Places，RPPs），《环境法典》（L562-1条款）明确划定了两类区域：其一为风险易发区，其二为未直接暴露于风险之中，但可通过采取相关措施避免风险加剧的区域。依据灾害风险等级，每类区域均需遵循强制性监管规范。该类监管规则通常将区域划分为三种类型： 1. "禁止建设区（即所谓"红区"）"：当灾害风险（D’aléa）等级较高时，通用监管规则为全面禁止建设行为； 2. "受监管约束区域（即"蓝区"）"：此类区域灾害风险等级为中等，相关建设项目需遵循适配问题类型的专项监管要求； 3. 未直接面临风险的区域，但在此类区域内开展的建设、工程、开发活动或农业、林业、手工业、商业及工业行为可能加剧既有风险或引发新风险，因此需遵守相关禁止性规定或约束性要求（详见《环境法典》L562-1条款）。 该第三类区域仅适用于自然风险易感场所（RPPs）。
