Pont-Audemer Flood Risk Prevention Plan

Spatial data set contained in the file of the Pont-Audemer Flood Risk Prevention Plan Risk prevention plans (RPPs) are the State's key instrument for risk prevention. Their objective is to control development in areas at risk. The development of a risk prevention plan generates a series of spatial data organized into several datasets. The same PPR may include spatial datasets containing: the main encompassing perimeters of the PPR (study perimeter, prescription perimeter, regulated perimeter); - restricted areas of the plan once approved. PPR regulations generally distinguish between ‘no-building zones’, known as ‘red zones’, where the hazard level is high and the general rule is a no-building zone; ‘prescribed areas’, known as ‘blue areas’ where the hazard level is medium and projects are subject to requirements adapted to the type of issue at stake and areas not directly exposed to risks but subject to prohibitions or requirements; - hazard zones represented on the hazard map used for risk analysis by crossing with the stakes, specifying for each zone the level of the hazards to which it is exposed; issues (people, property, activities, cultural or environmental heritage elements) threatened by a hazard and likely to be affected or damaged by it; - origins of the risk, i.e. the real-world entity which, by its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object locating the actual entity causing the risk.
