For PPRTs, the environmental code defines a single category of zones for zones (L515-15 et seq.): areas at risk. Unlike natural RPPs, PPRTs never have restricted areas that are not directly exposed to risk. Depending on the hazard level, each TRPP area is subject to an enforceable settlement. The PPRT regulations generally distinguish two 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. The instructions in the PPRT development guide add a gradation within the “red zones” and “blue zones”.
