Simple download service (Atom) of the dataset: PPRI Marne aval — Épernay sector — CCGVM — perimeter of the PPRi

This dataset contains the scope of exposure to flood risk of the public institution of intercommunal cooperation (EPCI) Communauté de Communes de la Grande Vallée de la Marne (CCGVM) which partly corresponds to the perimeter regulated by the PPRi prescribed by prefectoral decree of 12 October 2017. This partial perimeter on the CCGVM, will be public easement and will be included in easement PM1 upon approval.

Spatial resolution: 1/10 000

Genealogy:
The perimeter of the prescribed PPRi is provided in the Prefect’s prescription order. The regulated scope corresponds to the geometric aggregation of all the restricted areas included in the same PPRi. The scope of the study corresponds to the envelope of the EPCI concerned in which the hazards were studied.

本数据集涵盖跨社区合作公共机构（EPCI）——马恩大谷共同体（Communauté de Communes de la Grande Vallée de la Marne，缩写CCGVM）的洪水风险暴露范围，该范围部分对应2017年10月12日省长令所规定的防洪风险预防规划（PPRi）管控边界。该部分边界将纳入公共地役权范畴，经审批后将归入PM1号地役权范围。

数据集溯源：
法定防洪风险预防规划（PPRi）的边界载于省长发布的管控令中。本次管控范围为同一PPRi所涵盖全部受限区域的几何聚合结果。本数据集所依托研究的范围对应所涉跨社区合作公共机构的覆盖边界，该范围内已开展洪水灾害相关研究。
