DDT 91 — Yvette Flood Risk Prevention Plan (PPRI) Perimeter

The PPRI of l'Yvette was approved on 26 September 2006. This dataset contains the boundaries at the different stages of the PPRN; development of the PPRN: — Scope of limitation, — Perimeter d' study corresponding to #x27; envelope in which hazards have been studied., — Perimeter d' exposure to risks that corresponds to the perimeter regulated by the approved PPR. __Origin__ The perimeter of a prescribed PPR is usually provided in the prefect’s prescription order. The perimeter d' exposure to risks — or regulated perimeter — corresponds to the \#x27; geometric aggregation of l' all the restricted zones listed in the same PPR. The perimeter of the study corresponds to the envelope in which the hazards were studied. __Partner organisations__ DDT Essonne __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-0ddd35f5-2527-41f2-805b-58f3b137edf8) * [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/287bc45ac0aab3dac7dc2869de09a9761d55a9c6)
