Regulatory zoning of PPRN approved in Haute-Garonne

Regulatory zoning of Natural Risk Prevention Plans: flooding, terrain movement and avalanche. This includes RIPs (floods) and multi-hazard PPRNs. But this does not include dry RPPs (risk of clay withdrawal-swelling) that are in the layer: L_ZONE_REG_PPRS_031.TAB 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” where the hazard level is high and the general rule is the prohibition on construction; 2- “required areas” 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).
