Risk — 41DDT20100001 Restricted area of the revision of the RPP of the Commune of Blois en Loir-et-Cher

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 areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and 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, crafts, 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.

针对自然风险预防计划（Natural PPRs），《环境法典》（Environmental Code）的L562-1条款划定了两类区域：一是风险暴露区域，二是未直接面临风险但可预先采取措施规避风险加剧的区域。根据危险等级的不同，每类区域均需遵循可强制执行的管控要求。相关法规通常将区域划分为三类：1. 禁止建设区，亦称“红色区域”：该区域危险等级较高，通用规则为禁止建设；2. 约束管控区，亦称“蓝色区域”：该区域危险等级为中等，相关建设项目需遵循适配问题类型的管控要求；3. 未直接面临风险，但各类建设、工程、开发活动或农、林、手工、商业、工业类经营主体可能加剧既有风险或引发新风险的区域，需遵守相关禁止或管控要求（参见《环境法典》L562-1条款）。前述第三类区域仅适用于自然风险预防计划（Natural RPPs）。
