Sixteen cities in China have been identified by the central government to participate in Sponge City pilot projects. The goals is to update stormwater infrastructure so urban areas can properly management this resource onsite through retention, infiltration, treatment and controlled discharge. Low Impact Development (LID) design techniques will play a large role in meeting project targets.
GEO will begin LID design of the West Silk Road. This is a 4.2 km section of roadway located in the Hanzhong New Town. A system of vertical bioswale filters will provide stomrwater water quality treatment and protect the Xing Yuan Lake. This project is located in the City of Hanzhong, Shaanxi Province, PRC.
The experimental green roof at the Shenzhen University College of Engineering designed by the GEO team is entering its second year of growth and doing great. This 500 square meter facility has already experienced a 100yr event. In May 2014, the green roof and infrastructure did not flood while experiencing a record rainfall (592mm/72hrs). The City of Shenzhen did not fare as well. Globally, frequent and more intense storm events are becoming more common, green roofs are a tool to make our urban areas more resilient.
