Gally ru RIP Restricted Area — YVELINES

The Natural Risk Prevention Plan (PPRN) is a document produced by the State which regulates land use according to the natural risks to which it is subject. This ranges from the prohibition on construction to the possibility of building under certain conditions. A PPRI is a flood risk prevention plan. The PPRN is a regulatory prevention record that communicates risk areas to populations and planners and identifies measures to reduce vulnerability. Its purpose is to gather knowledge of the risks in a given territory, to deduce from it a delimitation of the exposed areas and to define requirements for urban planning, construction and management in risk areas, as well as measures to prevent, protect and safeguard existing buildings in that area. It makes it possible to orient development towards risk-free zones. 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 can be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of zones: 1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction; 2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The final document of the PPRN is composed of: · A presentation report containing an analysis of the phenomena taken into account, as well as a study of their impact on people and property, existing and future. The report shall also set out the principles for the preparation of the PPRN and the explanatory memorandum of the Regulation; · A regulatory map on a scale between 1/10 000 and 1/5 000 in general, which delimits the areas regulated by the PPRN; · A by-law that specifies the rules applicable to each zone.
