Plan for the prevention of natural hazards of landslides — Commune de Piquecos — Restricted area — Department of Tarn-et-Garonne

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 where measures may be planned to avoid d’#x27; exacerbate the risk. Depending on the level of d'aira, each zone is the subject of an opposable regulation. Regulations generally distinguish three types of zones: 1- ‘zones d' prohibition to build’, known as ‘red zones’, where the level of #x27; hazard is strong and the general rule is #x27; prohibition on building; 2- ‘zones subject to requirements’, known as ‘blue zones’, where the level of hazard is average and projects are subject to requirements adapted to the type of #x27; stakes; 3- areas not directly exposed to risks but where constructions, structures, development or agricultural, forestry, artisanal, commercial or industrial operations could aggravate or cause new risks, subject to prohibitions or requirements (cf. Article L562-1 of the Code of the Environment). The latter category is only applicable to natural PPRs. __Origin__ The noise levels emitted by a given infrastructure during an average day are evaluated using numerical models producing isophone curves translated into noise zones, according to the; index recommended for all modes of transport at European level, namely the Lden index and l' index Ln.The isophone curves, described by the resource N_BRUIT_ISOPHONE_L thus serve to delimit the external borders and, where appropriate, internal noise zones by range of #x27; indices. __Partner organisations__ DDT Tarn-et-Garonne __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-e57f635a-e7a7-4e52-9bad-226762362fec) * [COVADIS data standard: Table describing Noise Areas of (to be completed)(http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_BRUIT_ZBR_INFRA_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/4c2b7965a0a33cee2a0af6adf8f385bdea1bf5ee)
