This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of such perimeters is to be the consequence of an official act and to produce their effects from a defined date.This is the following: — prescribed perimeter contained in the prescription order of a PPR (natural or technological); — scope of exposure to risks that corresponds to the perimeter regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.This dataset contains the boundaries at the different stages of the development of the PPRN.

TwitterFor natural PPRs, the environmental code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures may be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. Regulations generally distinguish three types of zones: 1- “Building Prohibition Zones”, so-called “Red Zones”, when the hazard level is strong and the general rule is the construction ban;
2- “prescription zones”, known as “blue zones”, where the hazard level is average and projects are subject to requirements adapted to the type of issue;
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 (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural PPRs.

TwitterThe COVADIS data standard for risk prevention plans includes all the technical and organisational specifications for the digital storage of geographical data represented in the risk prevention plans (RPPs). The major risks consist of the eight main natural hazards foreseeable in the national territory: floods, earthquakes, volcanic eruptions, terrain movements, coastal hazards, avalanches, forest fires, cyclones and storms, and four technological risks: nuclear risk, industrial risk, risk of transport of hazardous materials and risk of dam failure. The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. The PPR tool is part of the Law of 22 July 1987 on the organisation of civil security, the protection of the forest against fire and the prevention of major risks. The development of a RPP is the responsibility of the State. It is decided by the Prefect. Whether natural, technological or multi-hazard, risk prevention plans have similarities. They contain three categories of information: • Regulatory mapping translates into a geographical delimitation of the territory concerned by the risk. This delimitation defines areas in which specific regulations apply. These regulations are easement and impose requirements varying according to the hazard level to which the area is exposed. The areas are represented on a zoning plan that fully covers the study area. • The hazards at the origin of the risk are contained in hazard documents which may be inserted in the presentation report or annexed to the RPP. These documents are used to map the different intensity levels of each hazard considered in the risk prevention plan. • The issues identified during the preparation of the RPP can also be annexed to the approved document in the form of maps. These similarities between the different types of PPR and the desire to achieve a good level of standardisation of PPR data have led COVADIS to opt for a single data standard, sufficiently generic to process the different types of risk prevention plan (natural risk prevention plans PPRN, technological risk prevention plans PPRT) This data standard does not consist of a complete modelling of a risk prevention plan dossier. The scope of this document is limited to geographical data in the RPPs, whether regulatory or not. Nor is the PPR standard intended to standardise knowledge of hazards. The challenge is to have a description for a homogeneous storage of the geographical data of the RPPs, since these data are of interest to several professions within the ministries responsible for agriculture, on the one hand, and ecology, and on the other hand, sustainable development.

TwitterCe jeu de données contient les périmètres de délimitation aux différents stades de l'élaboration du PPRN. Ces périmètres ont comme caractéristique d'être la conséquence d'un acte officiel et de produire leurs effets à compter d'une date définie. Il s'agit du : - périmètre prescrit figurant dans l'arrêté de prescription d'un PPR (naturel ou technologique) ; - périmètre d'exposition aux risques qui correspond au périmètre réglementé par le PPR approuvé. Ce périmètre approuvé vaut servitude d'utilité publique (PM1 pour les PPRN et PM3 pour les PPRT) ; - périmètre d'étude qui correspond à l'enveloppe dans laquelle ont été étudiés les aléas.
Origine
Le périmètre d'un PPR prescrit est généralement fourni dans l'arrêté de prescription pris par le préfet. Le périmètre d'exposition aux risques - ou périmètre réglementé - correspond quant à lui à l'agrégation géométrique de l'ensemble des zones réglementées figurant dans un même PPR. Le périmètre d'étude correspond à l'enveloppe dans laquelle ont été étudiés les aléas.

TwitterPour les PPR naturels, le code de l'environnement définit deux catégories de zones (L562-1) : les zones exposées aux risques et les zones qui ne sont pas directement exposées aux risques mais sur lesquelles des mesures peuvent être prévues pour éviter d'aggraver le risque. En fonction du niveau d'aléa, chaque zone fait l'objet d'un règlement opposable. Les règlements distinguent généralement trois types de zones : 1- les « zones d'interdiction de construire », dites « zones rouges », lorsque le niveau d'aléa est fort et que la règle générale est l'interdiction de construire ; 2- les « zones soumises à prescriptions », dites « zones bleues », lorsque le niveau d'aléa est moyen et que les projets sont soumis à des prescriptions adaptées au type d'enjeu ; 3- les zones non directement exposées aux risques mais où des constructions, des ouvrages, des aménagements ou des exploitations agricoles, forestières, artisanales, commerciales ou industrielles pourraient aggraver des risques ou en provoquer de nouveaux, soumises à interdictions ou prescriptions (cf. article L562-1 du Code de l'environnement) . Cette dernière catégorie ne s'applique qu'aux PPR naturels.
Origine
Les limites d'une zone réglementée sont représentées sur les documents graphiques du PPR. Les limites réglementaires sont généralement calées sur les phénomènes naturels, qui ne suivent ni le découpage cadastral ni les limites administratives. Un PPR détermine les limites des différentes zones réglementées en fonction de l'emprise calculée des phénomènes dangereux du site.Certains PPR peuvent parfois contenir des règlements associés à des figurés linéaires ou ponctuels (cavités, axe de ruissellement...). Les primitives graphiques linéaire et ponctuelle sont à utiliser respectivement dans ces cas de figure.

TwitterDatový standard COVADIS pro plány prevence rizik zahrnuje všechny technické a organizační specifikace pro digitální ukládání zeměpisných údajů, které jsou zastoupeny v plánech prevence rizik. Hlavní rizika se skládají z osmi hlavních přírodních nebezpečí předvídatelných na území státu: povodně, zemětřesení, sopečné erupce, pohyby terénu, pobřežní nebezpečí, laviny, lesní požáry, cyklony a bouře a čtyři technologická rizika: jaderné riziko, průmyslové riziko, riziko přepravy nebezpečných materiálů a riziko selhání přehrady. Plány prevence rizik byly stanoveny zákonem ze dne 2. února 1995 o posílení ochrany životního prostředí. Nástroj PPR je součástí zákona ze dne 22. července 1987 o organizaci civilní bezpečnosti, ochraně lesa před požáry a prevenci závažných rizik. Za rozvoj RPP odpovídá stát. O tom rozhoduje prefekt. Ať už přírodní, technologické nebo multi-nebezpečí, plány prevence rizik mají podobnosti. Obsahují tři kategorie informací: • Regulatorní mapování se promítá do zeměpisného vymezení území, jehož se riziko týká. Toto vymezení vymezuje oblasti, na které se vztahují zvláštní předpisy. Tyto předpisy jsou věcnými břemeny a ukládají požadavky, které se liší podle úrovně nebezpečnosti, které je oblast vystavena. Oblasti jsou zastoupeny v územním plánu, který plně pokrývá oblast studia. • Nebezpečí při vzniku rizika jsou obsažena v dokumentech o nebezpečnosti, které mohou být vloženy do obchodní zprávy nebo připojeny k RPP. Tyto dokumenty se používají k mapování různých úrovní intenzity každého nebezpečí zvažovaného v plánu prevence rizik. • Problémy zjištěné při přípravě RPP mohou být rovněž připojeny ke schválenému dokumentu ve formě map. Tyto podobnosti mezi různými typy PPR a přáním dosáhnout dobré úrovně standardizace údajů o PPR vedly společnost COVADIS k tomu, aby zvolila jednotný datový standard, který by byl dostatečně obecný pro zpracování různých typů plánu prevence rizik (plány prevence přírodních rizik PPRN, plány prevence technologických rizik PPRT) Tato datová norma nespočívá v úplném modelování dokumentace plánu prevence rizik. Oblast působnosti tohoto dokumentu je omezena na zeměpisné údaje v RPP, ať již regulační, či nikoli. Ani norma PPR nemá za cíl standardizovat znalosti o nebezpečnosti. Úkolem je získat popis homogenního uchovávání zeměpisných údajů RPP, neboť tyto údaje jsou zajímavé pro několik profesí v rámci ministerstev odpovědných za zemědělství a ekologii na jedné straně a za udržitelný rozvoj na straně druhé.
