Dataset Direct Download Service (WFS): 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).防洪风险规划（Flood Risk Prevention Plans）是核心的防洪风险防控工具。其目标在于明确防洪风险特征，并规范风险区域内的城市化开发活动，以降低人员与财产的易损性。 此类规范性管控文件需经与市镇政府及居民协商，并经省级政令发布后方可获批。该管控规定划分了三类区域： - “红区（red areas）”：灾害等级为高，通用规则为禁止建设； - “蓝区（blue zones）”：灾害等级为中等的区域，区内建设项目需遵循适配问题类型的管控要求； - 间接风险区：该区域未直接暴露于风险之中，但区内的建设工程、开发活动、农场、农林生产、手工业、商业或工业经营主体可能加剧既有风险或诱发新风险，需遵守相关禁令或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然型防洪风险规划（RPPs）。 PPRI属于公共役权（SUP PM1）。
