PPRN Vaucluse Floods (84) — Summary of Regulated Areas

This sheet provides access to localised data on regulatory zoning of approved RPP floods in the Vaucluse. The Environmental Code governs the establishment of PPRNs, including their regulatory zoning. This mapping document comes from the analysis of the territory subject to natural risk, from the point of view of the intensity of the natural phenomenon but also of the existence and vulnerability of the issues impacted. Synthetically, the regulatory zoning of PPRNs, including PPR Floods, delineates the following areas: — inconstructible areas, where the general rule is the prohibition on the establishment of new constructions, unless otherwise permitted under conditions; — construction areas, where the general rule is to allow new constructions to be installed in accordance with requirements adapted to the type of issue; Outside the areas demarcated in the regulatory zoning, urbanisation is not regulated under the PPRN, but may be regulated under other provisions, including those of the existing urban planning document. The objective of a PPR Floods is to limit the vulnerability of existing or future human issues (goods and people). Achieving this objective requires a thorough knowledge of the following elements and their interactions: The flood hazard at any point in the territory concerned; The issues affected by this hazard and their vulnerability to flooding or their capacity for flood expansion; The purpose of the regulatory zoning of a PPRI is to specify, for each point in the territory concerned, any prohibitions and requirements relating to construction so as to achieve that objective. Its preparation therefore results from the simultaneous consideration of these two components. It should be noted that some approved RIPs contain, in addition to the regulatory zoning, a map of reference ratings, which is necessary for the proper application of the RIP in soil law as it gives the altitude to be respected for the implementation of the floors of authorised projects. If applicable, this map is available in hard copy in town hall or prefecture and can be downloaded in PDF from the website of the Prefecture.
