Simple download service (Atom) of the dataset: Regulated areas of the Flood Risk Prevention Plans (PPRI) of the Seine-et-Marne department

Flood Risk Prevention Plans are the main flood risk prevention tool. Their objectives are to characterise flood risk and regulate the development of urbanisation in risk areas to reduce the vulnerability of people and property.
The regulatory documents are approved after consultation with the municipalities and residents and the issuance of the prefectural decree. The regulations distinguish three types of zones:
_ “red areas” where the hazard level is high and the general rule is the prohibition on construction;
_ areas subject to so-called “blue zones” where the hazard level is average and the projects are subject to requirements adapted to the type of issue;
_ areas not directly exposed to risks but in which constructions, works, developments or farms, agricultural, forestry, craftsmanship, comercial or industrial holdings 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.
PPRI is a utility bondage (SUP PM1).

洪水风险预防计划（Flood Risk Prevention Plans）是核心的洪水风险防控工具。其目标在于厘清洪水风险特征，管控风险区域内的城市化开发进程，以降低人员与财产的易损性。
该类管控文件需经与市政当局及居民协商，并发布地方政令后方可获批。
该管控方案划分了三类区域：
_ 红色区域（red areas）：该区域灾害等级较高，通用管控规则为禁止建设活动；
_ 蓝色区域（blue zones）：此类区域灾害等级为中等，相关工程需根据具体问题类型适配相应管控要求；
_ 间接风险区域：该区域未直接暴露于洪水风险中，但区内的建筑、工程、开发项目或农、林、手工艺、商业及工业经营场所，可能加剧既有风险或引发新的风险，需遵循相关禁令或管控要求（参照《环境法典》第L562-1条）。此类区域仅适用于自然型风险预防计划（RPPs）。
PPRI属于公共役权（SUP PM1）范畴。
