Restricted area of the natural risk prevention plan of Gaillard — Foron (Haute-Savoie) — approved on 29/07/2011

Risk Prevention Plans (RPPs) are the key instrument for risk prevention. Their objective is to control development in areas at risk. L' development of a risk prevention plan generates a series of spatial data organised into several datasets. This dataset describes the restricted areas of the plan once approved. PPR regulations generally distinguish between “zones d' prohibition to build”, so-called “red zones”, where the level of ' hazard is strong and the general rule is the “prohibition of construction”; the “prescription areas”, known as “blue zones” where the level of #x27; hazard is average and the projects are subject to requirements adapted to the type of #x27; stakes and areas not directly exposed to risks but subject to prohibitions or prescriptions __Origin__ 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 PPR determines the boundaries of the different restricted zones according to the calculated right-of-way of the hazardous phenomena of the site.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__ DDT Haute-Savoie __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-b847cb3b-6de4-4ba2-a78b-5b2a5b0634fc) * [COVADIS data standard: Restricted zone of a PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ZONE_REG_PPRN_AAAANNNN_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/7074ddd97675572708d72ace9812d12a2dd03726)
