Plan for the prevention of natural flood hazards — Municipalities of the Aveyron Sector — Document — Tarn-et-Garonne Department

The Risk Prevention Plans (RPPs) were established by the law of 2 February 1995 on strengthening the protection of the environment. They constitute the essential instrument of the State in the field of risk prevention. Their objective is to control development in areas at major risk. PPRs are approved by the prefects and generally carried out by the Departmental Directorates of 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, etc.). These plans may be in progress; development (prescribed), applied in advance or approved. The PPR file contains a submission note, a regulatory zoning plan and a regulation. Can be attached d' other graphic documents useful for understanding the approach (hazards, challenges...). Each PPR is spotted by a polygon corresponding to l' set of communes concerned with the scope of prescription when it is at the prescribing state; and l' envelope of restricted zones when it is at the approved state. This geographical table makes it possible to map existing PPRNs on the department. Each PPRN document existing in the geographic table N_DOCUMENT_PPRN is linked to the N_DOCUMENT_PPRN, using its GASPAR code in the format of “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and the number d' order of the associated PPR procedure in GASPAR): 1. to its administrative procedure; preparation (or revision) managed in the \#x27; GASPAR application, d' on the one hand, 2. its series of numerical constituent geographical data described by metadata sheet N_PPRN_AAAANNNN (#0001495) d' other. __Origin__ This table is rendered geometrically using the IAL perimeter (prescription perimeter when the PPR is prescribed or perimeter regulated when the PPR is approved).The geometry of the prescribed perimeter of {\#x27; a PPR is provided by the prefectural prescription order of this PPR. The geometry of the regulated perimeter of a PPR is constructed by l' geometric aggregation of polygons representing the zones restricted by the PPR.Source of georeferencing:- cadastral reference PCI (DGFIP) or BD Parcellar (IGN) name, version and news to be specified- Scan25 (IGN): number and year of l' edition to be specified- BD CARTO (IGN) or GeoFLA (IGN) (number and year of l' edition to be specified) for prescribed PPRs — List of prescribed and approved PPRNs on the department based on existing information in the; GASPAR application for monitoring PPR procedures. __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-b0ccae0e-4d98-4b7b-a4b8-1ef8974d5906) * [COVADIS data standard: PPRN document on the department...](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_DOCUMENT_PPRN_S) * [simple download of game and related documents](http://atom.geo-ide.developpement-durable.gouv.fr/atomArchive/GetResource?id=712ab7c8-4a32-4749-beb1-44d537450ee2&full=true) * [access to the single single download service of the game and associated documents](http://atom.geo-ide.developpement-durable.gouv.fr/atomMetadata/GetResourceDescription?id=712ab7c8-4a32-4749-beb1-44d537450ee2&scope=INTERNET) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/eb599e9426e3664bc15602fc8f8268f375d75e60)
