The application of low impact development (LID) techniques preserves the predevelopment
hydrologic environment and minimizes the effects of urbanization by reducing impervious areas
and increasing green areas. The LID method also utilizes decentralized stormwater management
approaches that attempt to manage stormwater at the location where rainfall occurs. The purpose of
this study is to demonstrate the integrated effects of the LID technique for stormwater management
such as flood control, improvement of water balance, and reduction of nonpoint source pollution by
comparing it with conventional development methods. The economic efficiency of the LID method
was also analyzed. These analyses were conducted for the Songsan Green City in the Republic of
Korea, which is the construction site for a new urban area. The results show that flood peak flow
and runoff volume were decreased by 4.81% and 8.37%, respectively, by applying the LID technique.
Evapotranspiration and infiltration with the LID method were increased by 1.1% and 2.6%, respectively,
compared with the conventional development method. The removal efficiency for nonpoint
source pollution with the LID method was also 14.6% higher than with the conventional development
method. Furthermore, the construction cost of the LID method was 9% lower than the cost
of the conventional development method. These results show that the LID method is superior to
the conventional development method in terms of stormwater management and can also reduce
construction costs.
