Dataset Direct Download Service (WFS): PPRI Marne aval — Épernay sector — CCPC — PPRi perimeter

This dataset contains the scope of exposure to flood risk of the public institution of intercommunal cooperation (EPCI) Communauté de Communes des Paysages de la Champagne (CCPC) which partly corresponds to the scope regulated by the PPRi prescribed by prefectoral decree of 12 October 2017. This partial perimeter on the CCPC will be public easement and will be entered in easement PM1 upon completion of the 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（Etablissement Public de Coopération Intercommunale，简称EPCI）——香槟景观市镇共同体（Communauté de Communes des Paysages de la Champagne，简称CCPC）的洪水风险暴露范围，该范围部分对应2017年10月12日省长令规定的防洪风险规划（PPRi）管控范畴。该CCPC辖区内的该部分范围将纳入公共役权体系，并将在审批完成后录入PM1役权台账。

数据集溯源脉络：
法定防洪风险规划（PPRi）的管控范围由省长令发布。其管控边界为同一PPRi涵盖的全部受限区域的几何聚合结果。本数据集的覆盖范围即为所涉跨社区合作公共机构的全域辖区，该范围内已开展洪水灾害相关研究工作。
