PPRT — Regulated Area of a PPRT — CAL Ecrouves (54)

For PPRTs, the code of l'environment defines a single category of zones for zones (L515-15 et seq.): areas exposed to risk. Unlike natural RPPs, PPRTs never have restricted areas that are not directly exposed to risks. Depending on the level of d'aira, each zone of the PPRT is the subject of an opposable regulation. PPRT regulations generally distinguish two types of zones: 1- “zones d' prohibition to build”, so-called “red zones”, when the level of #x27; hazard is strong and the general rule is #x27; prohibition to build; 2- “prescription zones”, so-called “blue zones”, when the level of #x27; hazard is average and projects are subject to requirements adapted to the type of #x27; issue. The instructions in the guide d' PPRT development add a gradation to the “red zones” and “blue zones”. __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 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__ DDT Meurthe-et-Moselle __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-e168b0c5-f216-4e52-8a47-1f950568e168) * [basic URL of wms/wfs services on the Internet](http://ogc.geo-ide.developpement-durable.gouv.fr/wxs?map=/opt/data/carto/geoide-catalogue/1.4/org_38050/afb6ae99-519f-4c20-a41e-130889a1c520.internet.map) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/350d89b9390e3ebac0d9da93e09d11cdeffb4a08)
