What this layer shows

Périmètre de contrainte karstique, marking a natural hazard or a major geotechnical constraint on development: collapse, chantoir or depression. The permitting authority may require the applicant to carry out preliminary studies and take specific measures, without construction being prohibited as such. The degree of constraint (low, moderate or high) is given with each perimeter.

Constraints

What a consultancy or a notary checks first in Wallonia: Natura 2000 and its unités de gestion, reserves and Ramsar sites, plan de secteur and additional prescriptions, flood zones and karst, abstraction points, listed properties and remarkable trees, pre-emption, sites à réaménager and Habitat Permanent. The other municipal instruments and the rest of the water have their own set.

Water and risks

Water as defined by the Code de l'Eau and the risks that come with it: flood hazard and flood zones, protection works, karst constraints, prevention and surveillance zones around abstraction points, nitrate vulnerable zones, water bodies, hydrographic network and bathing areas.
