of these storms caused the rain garden to overflow. Rain Gardens in this sub-humid loess region of Xi'an China, are Low Impact Developments (LID). China plans to implement a "sponge city" program in response to urban flooding. This program will prioritize the natural environment and will include rain gardens, green roofs, wetlands and more permeable surfaces to slow down storm water retention.
