Risk area of the PPRT of the Gratecap establishment in the municipality of La Rochelle in Charente-Maritime

Area exposed to one or more hazards shown on the hazard map used for PPR risk analysis. The map d'random is the result of the study of hazards whose goal is to evaluate the intensity of each hazard at any point in the zone of study. The evaluation method is specific to each type of hazard. It leads to the delimitation of a set of zones on the perimeter d'study constituting a graduated zoning according to the level of l'aira. L' attribution of Â#x27;A level of #x27; hazard at a given point in the territory takes into account the probability of #x27; occurrence of the dangerous phenomenon and its degree of Â#x27; intensity. For PPRTs levels d'aira are determined effect by effect on maps by type of d' effects and overall according to an aggregate level on a synthesis map. All hazard zones shown on the hazard map are included. Areas protected by protective works must be represented (possibly specifically) because they are always considered subject to the hazard (case of rupture or d' inadequacy of the work). Hazard zones can be described as elaborated data as they result from a synthesis using several calculated, modelled or observed data sources. These source data are not affected by this class of objects but by another standard dealing with the knowledge of hazards. Some areas of the perimeter of the study are considered “zero or insignificant hazard zones”. It is the areas where the hazard has been studied and is zero. These zones are not included in class d'objects and n'are not to be represented as zones d'aira. __Origin__ To be specified by the supplier, in particular methodology used and assumptions used by the service provider 16/03/2016 Changing the structure of the field ID_MAET table increases to 50 characters Added AAC of Le Poujet 22/03/2016 Addition date and fixed link prefectoral delimitation AAC Vacquières 26/04/2016 AAC renaming of L' Commune Aumède de Le Pouget 04/10/2016 Delimitation AP of the Poujet AAC Addition of 3 AACs: Libron, Villeneuve-Les-Maguelone and Bérange-Garrigues bass 17/11/2016 Fixed entry error Garriges instead of Garrigues 10/11/2017 Change structure to shape format 27/12/2017 AAC of Villeneuve les Maguelone: scope redefined by a new preliminary study 03/01/2018 Verification of data with Fabrice Dortel The site https://aires-captages.fr/aires-alimentation-captages/carte-des-aac is not up to date Renaming of the AAC Villeneuve-les-Magelonne — Fles During the year 2019, 2 new AACs will have to be delimited on Servian (Marseillette) and Péroles (Vauguières F1 and F2). 14/10/2019 Libron AAC Delimitation Order Delimitation Order of l'AAC Bérange Garrigues bass __Partner organisations__ DDTM Charente-Maritime __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-578732bb-f776-4620-8f54-b10201db56f9) * [COVADIS data standard: Catchment Feed (AAC) for use in AEP](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_AAC_AEP_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/b056fc12c66e8f98f30637ca8ebb3a1cf3f1a040)
