Restricted area of the PPRT from Vouzelaud to Brou (Eure-et-Loir)

For PPRTs, the environmental code defines a single category of zones for zones (L515-15 et seq.): areas at risk. Unlike natural RPPs, PPRTs never have restricted areas that are not directly exposed to risk.Depending on the hazard level, each TPP area is subject to enforceable regulation. The PPRT regulations generally distinguish between two types of areas:1- “Building prohibited areas”, known as “red zones”, where the hazard level is high and the general rule is the construction ban;2- “prescribed areas”, so-called “blue zones”, where the hazard level is medium and the projects are subject to requirements adapted to the type of issue. The instructions of the PPRT development guide add a gradation within the “red zones” and “blue zones”.针对PPRT，《环境法典》针对L515-15及后续条款所涉及的区域，划定了单一类别的区域：风险区域。与天然RPP不同，PPRT从不包含未直接暴露于风险中的受限区域。根据危险等级的不同，每个TPP区域均需遵守强制性监管要求。PPRT法规通常将区域划分为两类：1. 被称为"红区"的建筑禁止区域，该区域危险等级较高，核心规则为禁止建设；2. 被称为"蓝区"的指定区域，该区域危险等级为中等，相关项目需遵守适配问题类型的监管要求。PPRT编制指南的相关说明还在"红区"与"蓝区"内部增设了分级机制。
