Dataset Direct Download Service (WFS): R111-3 Restricted Area of Pont du Chateau(63DDT19880005) approved on 05-01-1988 — Puy-de-Dôme
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.
The risk perimeter R111-3 field movement of Pont du chateau includes 2 zones:
— Internal perimeter: is the area of mining work increased by an area of influence calculated at an angle of 35° to the vertical, which is the area with the highest risk of subsidence.
— external perimeter: corresponds to reconnaissance galleries. Lower risk of subsidisation than in the internal perimeter. Authorised constructions with prescription
