- Abstract:
- Tianjian Garden, a 20-year-old residential quarter in Shenzhen has been renovated into a sponge residential area from the perspective of problem orientation and overall improvement of landscape environment. While solving the problems of ponding in the courtyard and basement roof leakage, the courtyard had been endowed with functions of natural storage, stagnation and purification of stormwater to create more fun by a three-dimensional sponge layout including change of site runoff routine, reshape of landscape pattern, and integration of sponge city technology with landscape. Innovative technologies like thin sunken green land and light permeable pavement have been used to solve the problem of setting sponge facilities under the load limit of basement roof. After long-term monitoring of the main stormwater outlet, the local total annual runoff control rate has been raised from about 17% to above 65%, which is a successful exploration of livable and sponge reconstruction in old residential quarters.
