Mesnil Martinsart PPRI Restricted Area

For natural PPRs, the code of l'environment defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but on which measures can be foreseen to avoid d’#x27; aggravate the risk.Depending on the level of #x27; hazard, each zone is the subject of an opposable settlement. The regulations generally distinguish between three types of zones:1- the ‘zones d' prohibition of construction’, known as ‘red zones’, where the level of ' hazard is strong and the general rule is the prohibition on construction;2- ‘areas subject to requirements’, known as ‘blue zones’, where the level of #x27; hazard is average and the projects are subject to requirements adapted to the type of d' at stake;3- areas not directly exposed to risks but where constructions, structures, development or agricultural, forestry, artisanal, commercial or industrial activities could exacerbate risks or cause new ones, subject to prohibitions or requirements (see Article L562-1 of the Code de l' environment). The latter category is only applicable to natural PPRs. __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 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__ DDTM Somme __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-9cf22af7-7443-4504-adcf-c3c0cdf4bea2) * [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/f8a39bb7d3aa9c7337d8d9140d286b6883af2cf0)
