Multi-hazard PPR to inform the types of risk addressed in the Montdidier PPRM

The plans for the prevention of natural hazards (PPRN) were established by the law of 2 February 1995 on the strengthening of the protection of the environment. They constitute the essential instrument of the State in the field of risk prevention. Their objective is to control the development in areas exposed to a major risk.The PPRNs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through construction bans or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices...).The plans may be in progress; preparation (prescribed), applied in advance or approved.The PPRN file contains a presentation note, a regulatory zoning plan and a regulation. Can be attached d' other graphic documents useful for understanding the approach (hazards, challenges...). Each PPRN shall be identified by a polygon corresponding to the prescribing perimeter set of municipalities concerned when it is at the prescribed state; and l' envelope of restricted zones when it is at the approved state. This geographic table makes it possible to map existing PPRNs on the department.Each PPRN document in this geographic table is linked to the GASPAR code “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and order number of the associated PPRN procedure in GASPAR): 1. to its administrative procedure; preparation (or revision) managed in the \#x27; GASPAR application, d' on the one hand, to its series of constituent geographic data described by the metadata sheet N_PPRN_AAAANNNN, d' and __Origin__ combination of a technological risk given to a multi-hazard PPRN __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-57edb85c-80bf-4860-b72c-2fd3816165af) * [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/c3702259ad36459f729ab1d75292d775856b09b4)
