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.
In the case of this RPP, there are 3 categories of zones:
— R: red zone to preserve from any new urbanisation
— O: area Orange corresponding to non-urbanised areas where only certain particular constructions can be authorised.
This zone is divided into 3 sub-zones:
—O1: unurbanised area affected by low-level localised collapse
—O2: non-urbanised area affected by a low level compaction and/or slippage
—O3: non-urbanised area affected by low-level localised collapse and contingencies and/or low-level slippage
— B: blue zone corresponding to mine hazard zones in an urbanised area where constructive arrangements are made to guarantee the safety of property and people.
This zone is divided into 3 sub-zones:
—B1: urbanised area affected by low-level localised collapse
—B2: urbanised area affected by a low level compaction and/or slippage
—B3: urbanised area affected by localised low-level collapse and low-level settlement and/or slippage
