A flood hazard implies a hindrance for urban and social development, especially since a further increase of event frequency and intensity due to climate change can be assumed. Traditional flood protection measures are partly disputed for small-scale areas and large construction heights, as they are difficult to integrate into the local and landscape appearance. In the search for suitable and sustainable alternative measures, which increases the resilience of the area at the same time, the present study focuses on house lifting as an area-specific flood protection measure. The aim was to develop a corresponding solution approach and to evaluate it in an interdisciplinary way.
The Elbe village of Brockwitz (municipality of Coswig) with a 1000-year history serves as an example, on the basis of which positive effects for house lifting are demonstrated. The village was severely affected by the flood events in 2002 and 2013. Due to the local conditions, a stationary flood protection facility (dyke) is contested here, as it would represent a significant intervention in the cultural landscape and the historic townscape. At the same time, it is possible to protect only a relatively small number of buildings with such a massive intervention, so that this project - from an overall Saxon perspective - has a low priority and the implementation of the measure in the near future is questionable.
This prompted the identification of suitable alternatives for damage and risk reduction, an assessment of their feasibility, and an evaluation of the consequences for the village, its residents, and the surrounding area. The aim is to maintain or improve the attractiveness and quality of life of the town and the natural functions of the Elbe floodplain. Coswig is pursuing an innovative solution approach of house lifting for the flood-affected houses in order to mitigate the flood risks in accordance with principles of sustainability and of avoiding subsequent operative costs
