Regulated area of the Riomoise Agglomeration PPRNPI (63DDT20140003) approved on 18-07-2016 — Puy-de-Dôme

For 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 can be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. This RPP consists of 7 restricted areas: — Rfu: highly urbanised area in which a prohibition principle applies, taking into account the highly urbanised nature — UK: Other urbanised area and area of activity in which there is a prohibition principle — VD: little or no urbanised area in which the PPRNPi must ensure the free flow of water and the conservation of flood fields — O: low or medium-risk urbanised area to which the principle of authorisation applies provided that projects take flood risk into account in their design — V: little or no urbanised area in which the PPRNPi is responsible for the free flow of water and the conservation of flood fields. Some land use related to the management of these areas may be permitted. — Gold: residual hazard area to which the licensing principle applies provided that projects take into account flood risk in their design, including in non-urbanised areas at the time of the development of the PPRNPi — B: area corresponding to an exceptional return flood 1000 years in which the principle of regulating the only institutions relevant for crisis management, useful for a rapid return to normal, the failure of which poses a high risk to persons and installations classified for environmental protection which may cause significant pollution or risk
