Dataset Direct Download Service (WFS): PPR USTARITZ (64DDTM20160012) — Perimeter of the Ustaritz Flood Risk Prevention Plan (PPRN-PPRI) (64547), Pyrenees-Atlantiques department

This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a specified date. This is the following: — prescribed scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied. Table of perimeters identified during the study of a PPR. This table contains as a minimum the prescribed perimeters for RPPs in the prescribed state and the prescribed and risk exposure perimeters for approved RPPs.本数据集涵盖PPRN（PPRN）不同发展阶段的边界范围。此类边界的特征为均由法定行为所产生，并自指定日期起生效，具体如下： — 源自PPR（PPR）规定令的规定范围（涵盖自然类与技术类PPR）； — 与获批RPP（RPP）规制范围相对应的风险暴露范围，该获批边界属于地役权（utility easement）（其中PPRN对应PM1，PPRT对应PM3）； — 研究范围，即开展灾害研究的覆盖边界。 PPR研究过程中确定的边界范围表： 该表至少包含处于规定状态的RPP的规定边界范围，以及获批RPP的规定边界范围与风险暴露边界范围。
