{ "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 0, "name": "Contraintes physiques liées aux éboulements", "type": "Feature Layer", "description": "Cette couche de données décrit les zones pour lesquelles des contraintes physiques liées aux éboulements s\u2019appliquent.\n\nLes contraintes physiques liées aux éboulements sont caractérisées par deux zonages différents :\n- les périmètres rouges correspondant aux zones de contraintes majeures pour l\u2019urbanisation\n- les périmètres noirs correspondant à la localisation des parois abruptes ou rochers affleurants\n\nLes versants où l\u2019inclinaison de la pente est supérieure à 30 degrés sont catégorisés selon le degré de contraintes urbanistique qu\u2019ils engendrent. Ils constituent une contrainte géotechnique « simple » Ils ne constituent pas, en eux-mêmes, une contrainte géotechnique majeure pour l\u2019urbanisation au sens du CoDT.\n\nCette couche est le résultat d\u2019une seconde étape du travail qui a consisté à définir des zones de contraintes majeures sur base des versants identifiés comme particulièrement sensibles. Les parois rocheuses présentant un risque possible pour les constructions humaines localisées à proximité, ont été mises en évidence. Un travail de terrain plus approfondi a alors été effectué afin de fixer un niveau de risque pour les versants et de délimiter des périmètres au sein desquels des contraintes liées aux éboulements sont vraisemblables.\n\nLes aires ainsi délimitées n\u2019impliquent pas nécessairement l\u2019interdiction d\u2019y construire, mais elles avertissent d\u2019un niveau de risque qui doit faire l\u2019objet d\u2019une étude géotechnique spécifique. Les pouvoirs publics veilleront à en avertir les candidats bâtisseurs.\n\nPlus d'informations sur cette donnée : http://geoportail.wallonie.be/catalogue/2ee5842e-df8b-41a6-824a-2c3d8a90fbf0.html",
