Sponge City Hefei - Eco Shore, Hefei/Anhui

Various near-natural areas in the southern part of Hefei Sponge City Park together form the eco shore. At a greater distance from the urban residential areas of the new city, species-rich, protected water biotopes are being created here by remodelling the bank structures of the reservoir.
The dilapidated existing concrete embankment is being repaired and extended by a foreshore. This so-called eco-berm made of bamboo mats, gravel, sediment, wood and large stones will be placed on top of the existing structure and provide new habitats for water-loving plants and animals. The plant species introduced here improve the water quality by serving as a food source for bacteria that purify the water of the reservoir through natural processes.
An existing woodland area is being reforested and developed into a dense urban forest, which has a positive effect on the microclimate and biodiversity. In addition, a retention soil filter hidden in the forest takes on hydrological functions. Rainwater is cleaned here and then channelled into the lake.
The former fish ponds are being transformed into shallow water zones with bird islands and beaches. These areas, which are inaccessible to humans, provide important refuges for endangered local bird species. A panoramic platform allows people to experience the protected areas and opens up wide views across the lake. The species-rich, shallow banks create additional retention space in the event of heavy rainfall. Along the neighbouring main road to the south, a new layer of trees filters the fine dust particles.
