It has become a hot focus in urban water resources research and practices globally. In this context, in order to provide an international forum for stormwater management professionals to present the latest developments, technologies and case studies related to low impact development （LID） and green infrastructure （GI） technology, the 2016 International Low Impact Development Conference was organized and held. The Conference was jointly sponsored by the Water Industrial Society of the Chinese Society of Civil Engineers, the Water Environment Research Institute of the American Society of Civil Engineers and the Chinese Academy of Engineering. Organizers included Tsinghua University, Peking University and Beijing University of Civil Engineering and Architecture.展开更多

However, due to high price of land and additional expense for LID construction in highly urbanized areas, the developers of real estate would not like to proceed LID exploitation. Floor area ratio （FAR） refers to ＂the ratio ofa building＇s total floor area to the size of the piece of land upon which it is built.＇＂ Increasing FAR indicates that the developers can construct higher buildings and earn more money. By means of awarding FAR, the developers may be willing to practice LID construction. In this study, a new residential district is selected as a case study to analyze the trade- offbetween the runoffreduction goal achieving by LID practices and the incentive of awarding FAR to promote LID construction. The System for Urban Stormwater Treatment and Analysis IntegratioN （SUSTAIN） model is applied to simulate the runoff reduction under various LID designs and then derive the Pareto-optimal solutions to achieve urban runoff reduction goals based on cost efficiency. The results indicates that the maximum surface runoff reduction is 20.5%. Under the extremity scenarios, the government has options to award FAR of 0.028, 0.038 and 0.047 and the net benefits developers gain are 0 CNY, one million CNY and two million CNY, respectively. The results provide a LID construction guideline related to awarding FAR, which supports incentive policy making for promoting LID practices in the highly urbanized areas.展开更多
