PPR URT (64DDTM19970015) — Perimeter of Urt’s Flood Risk Prevention Plan (PPRN-PPRI) (64546), 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.本数据集包含PPRN（PPRN）发展各阶段的边界信息。此类边界均由官方行为创设，并自指定日期起产生法律效力，具体如下： — 自然或技术类PPR（PPR）处置令中载明的法定范围； — 风险暴露范围：对应经核准的RPP（RPP）所规制的范围，该核准边界为公用役地（PPRN对应PM1，PPRT（PPRT）对应PM3）； — 研究范围：即开展危险源辨识研究的覆盖边界。 本数据集附带PPR研究过程中确定的边界表。该表至少涵盖处于法定状态的RPP的法定边界，以及经核准RPP的法定边界与风险暴露边界。
