Description

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. 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 latter category applies only to natural RPPs. This RPP defines 2 main areas: — red: principle of prohibition on construction — orange: principle of permission to build with prescription These two areas are themselves subdivided into 6 sectors: R1: Flood Expansion Fields in Low Hazard R2: Flood Expansion Fields in Medium Hazardous R3: Zone of strong hazards R3u: Urban centre area subjected to a severe hazard O1: low-risk urbanised area O2: urbanised Medium Hazardous Area
