Seoul metropolitan has established a vision as ‘Healthy water-cycle city’ to restore urban water-environmental as natural water-cycle. Therefore, various infiltrative Low Impact Development (LID) facilities are constructed and operated, however, benefit analytic plans for systematic valuation are insufficient. In this study, to analyze various benefits of these kinds of infiltration facilities, contents for benefit analysis were selected and categorized. As a result of quantification and valuation, infiltration storage tank and permeable pavement showed the total benefit as 0.99 dollar/yr·m2 for infiltration storage tank and 1.10 dollar/yr·m2 for infiltration storage tank. Characteristics of benefit distribution were various reflecting characteristics of each infiltration facility (Wastewater treatment saving: 88~90%, Energy saving: 4%, Air quality improvement: <1%, Climate change adaptation: 5~7%, Respiratory health care: <1%). As further studies, the synergy effects by integrated LID systems would be evaluated such as prevention of heat island based on suggested benefit assessment plans for each LID facility
