PPR LONS (64DDTM20050022) — Perimeter of the LONS Flood Risk Prevention Plan (64348), department of Pyrénées-Atlantiques.

This dataset contains the boundaries at the different stages of the PPRN; 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 defined date. It is: — prescribed perimeter set out in the prescribing order of n°#x27; a PPR (natural or technological); — perimeter d' exposure to risks that corresponds to the perimeter regulated by the approved PPR. This approved perimeter is a public utility easement (PM1 for PPRNs and PM3 for PPRTs); — perimeter d' study corresponding to #x27; envelope in which hazards have been studied. Table of perimeters identified during the study of a PPR. This table contains as a minimum the prescribed perimeters for PPRs at n°#x27; prescribed status and prescribed perimeters and d' exposure to risks for approved PPRs. __Origin__ 2014: COVADIS standardisation of the digital data of the PPRn of the departments of the Aquitaine region. The boundaries of a restricted zone are represented on the graphical documents of the PPR. Regulatory limits are generally set on natural phenomena, which do not follow cadastral or administrative boundaries. A PPRT determines the boundaries of the different restricted zones according to the calculated right-of-way of the site’s hazardous phenomena. Some PPRs may sometimes contain regulations associated with linear or punctual figures (cavities, runoff axis...). The linear and point graphics primitives are to be used in these cases respectively. __Partner organisations__ DDTM Pyrénées-Atlantiques __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-2170ac9e-30d4-4cef-970e-d270cf0b1848) * [COVADIS data standard: Risk Prevention Plan PPRN PPRT](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?id=15) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/ef07751dfb892cb7ceb684ac643454a47ebe5f26)
