Gefahrenhinweisbereich großflächige Senkungsgebiete

A large-scale subsidence takes place in the Bad Reichenhall basin (Starzmann 1979:114). This subsidence area was demarcated on the basis of the site plan contained in this publication and on the basis of the geological and tectonic conditions. Since the leveling cited does not cover the entire Reichenhall Basin, the possible subsidence area has been extended to the valley areas potentially affected by subsidence, in part with a safety margin. For a customary local development, the subsidence there is usually irrelevant. Only in the case of large and sensitive structures, damage due to differences in settlement cannot be ruled out. Subsoil and foundation reports have to take this special problem into account if necessary. Large-scale subsidence is also known from the area around the Grögern Weiher in Bayerisch Gmain. The demarcation of this area was based on the files at the LfU. The documents available to the LfU do not fully cover the subsidence area. A demarcation, especially to the south-west, is therefore only provisional. An even further extension of the subsidence area is possible, but there are no concrete indications of this. In any case, in the Grögern Weiher subsidence area, the preparation of subsoil and foundation reports that take this problem into account is recommended.
