Pilot City of National Sponge Cities
Sponge city, a conception of stormwater and flood management of modern cities, refers to the elasticity of a city in response to climate change and natural disasters brought by rainstorms. In December, 2013, President Xi Jinping proposed the conception of building sponge cities that can flexibly reserve, permeate, and purify water. In November, 2014, Ministry of Housing and Urban-Rural Development of the People’s Republic of China issued the Technological Guidelines for Constructing Sponge Cities. Then, in December, the first batch of constructing national sponge cities was open for application, and over 130 cities took part in the application. Finally, 16 cities were selected as the pilot cities. Changde, with 10 years’ experience of constructing sponge cities, successfully entered into the list.
In October, 2018, experts from Office of Housing and Urban-Rural Development of Hunan Province went to Changde to review its sponge city construction work. After listening to the report from the Construction Bureau of Changde and on-spot checking, the experts agreed that Changde’s construction work was effective and satisfying, and after three years of construction, the appearance and quality of Changde City was effectively improved. During the construction, Changde issued some supportive policies, compiled a series of technological standards, and conducted some projects that can serve as references for other cities to construct sponge cities.
