Resi2 Rick: Flood Resistance and Resilience in Ricklingen, Hanover (Germany)

Abstract

This paper explores how factors of flood resistance and resilience are addressed within the development of an area in Ricklingen, a hydro-geologically vulnerable district in the southwest of Hanover. The already existing dyke as a flood control and resistance measure offers protection against fluvial floods but does not offer protection for pluvial or flash floods and further intensification of extreme weather events. In order to adapt to climate change, this paper proposes the establishment of ditches that relieve stress from the drainage system and ponds and green roofs to evacuate intense rainfalls. The City of Hanover has already established a transparent information base on flood precaution, response and recovery and initiated a funding programme for roof and facade greening and land reclamation. In addition to these measures, this proposal foresees awareness-raising campaigns, resilience meetings and supplemental incentive schemes to encourage civil initiatives and actions such as small retention basins on private property. Besides, the high recreational value of the landscape should be further strengthened to support a close connection between people and nature.
