Flood protection for streams: Flood overflow in the spa gardens completed
After intensive planning and several months of construction, work on the construction of the swallowing fountain in the spa gardens has been completed. The monumental natural stone cladding was installed on the ten-meter-long overflow sill in the spa park pond.
The aim of urban protection measures is to minimize damage even in the event of a 100-year flood. However, preventive flood protection remains a joint task: in addition to municipal measures, owners are also responsible for their own property protection. The spa gardens around the Kurhaus are being made "climate-ready": a flood overflow is being built to counteract the increase in heavy rainfall caused by climate change.
The surrounding green spaces are now being gradually restored. The area should be fully reintegrated into the park landscape by early summer. The circular path around the Kurparkweiher pond is expected to be open to the public again from Thursday, May 29. Only planting work will be carried out in the former construction site area, but this will not restrict access.
"With the swallow well, an important building block for protection against heavy rain damage around the Kurhaus and for the adjacent inner city areas has been implemented. With this project, we are also making an important contribution to safety during heavy rainfall events," says Mayor and Head of the Environment Department Christiane Hinninger.
Despite weather-related delays during the construction phase, the new overflow sill was installed and put into operation as planned. It now allows excess water from the Rambach - which the Kurparkweiher cannot absorb - to be discharged into the historic Rambach canal below Wilhelmstraße in a controlled manner during heavy rainfall. Flooding damage such as in 1999 and 2014 should therefore be a thing of the past. Back then, heavy rain caused flooding in Sonnenberg, Rambach and around the Kurhaus Wiesbaden and the underground car park behind it. As a result, the city had already started to make the Rambach more flood-proof years ago with an initial flood protection extension in Sonnenberg. Embankment walls were raised, narrow sections removed or widened and new footbridges built. Other elements include a future flood retention basin in Rambach and the Schluckbrunnen flood overflow in the Kurparkweiher pond. The city received funding for this from the state's water development and flood protection program.
The work required intensive coordination between the environmental department and many stakeholders from planning, monument protection, the nature conservation and water authorities as well as TriWiCon's spa park management. The project also met with great interest from the public during the construction period. Numerous Wiesbaden residents came to find out more about the background and progress of the work during regular free guided tours and information boards on site.
