Sichuan to promote the implementation of sponge city construction

Rainwater can be through the urban ground natural accumulation, natural infiltration, natural purification, reduce urban waterlogging, so "will breathe"Sponge CityThere will be more and more in Sichuan. A few days ago, the General Office of the Provincial Government issued the "Implementation Opinions on Promoting the Construction of Sponge Cities" (referred to as the "Implementation Opinions") to speed up the construction of sponge cities in our province. The "Implementation Opinions" proposed that our province will comprehensively adopt various methods such as source emission reduction, process control, and system governance, and through measures such as "seepage, stagnation, storage, purification, use, and drainage", scientifically plan and coordinate the implementation of sponge-type buildings The construction of 6 types of key projects including communities, roads and squares, parks and green spaces, public service facilities, drainage and waterlogging prevention facilities, and water system protection and restoration, build a virtuous urban water cycle system with self-purification and self-infiltration, proper storage and drainage. Focus on the national sponge city construction pilot in Suining City and the provincial sponge city construction pilot in 5 prefecture-level cities and 10 county-level cities, and carry out the provincial sponge city project demonstration. By 2020, more than 20% of the urban built-up areas in the province will be able to absorb and utilize 70% of the rainfall locally. By 2030, more than 80% of the province's urban built-up areas will reach the above targets. The "Implementation Opinions" require all localities to pay close attention to the preparation of plans. Cities and counties will complete the preparation of special plans for sponge city construction by the end of December 2016. The province's 300 "hundred town construction action" pilot towns, in accordance with the concept of sponge city construction to re-examine the construction plan.
According to the "Implementation Opinions", outdoor non-motorized roads, squares, parking lots, and sports grounds in new buildings and residential communities should be paved with permeable water; green isolation belts and green belts on both sides of new roads in sponge-type cities should be used according to local conditions. Concave green spaces, planting grass ditches and other forms to increase the absorption of rainwater by road green spaces.
Sponge type park green space should be constructed according to local conditions, such as artificial wetland, rain garden, concave green space, grass planting ditch, multi-functional water storage or seepage storage green space and other facilities. All kinds of large-scale public construction projects, such as administrative organs and schools, should reduce the hard pavement area of buildings and squares. The "Implementation Opinions" proposes to vigorously promote the PPP model, and encourage social capital to participate in the construction and operation management of sponge cities through various forms such as user fees, government fees, and feasibility gap subsidies.
