Storm water management approach to increase the quality of urban streetscape in Sudirman Street, Bogor City

Abstract

The storm water management approach is still scarce in developing countries. Streetscape is one of the city’s elements that suitable for storm water management because of the dominance of impervious surface. Storm water runoff will cause damage of streetscape facility and river biodiversity in the long term due to the pollutant consist on it. This study focuses on the use of hydrological analysis to determine the main problem regarding the drainage capacity and the design solution with storm water management approach. The case study takes place in Sudirman Street, Bogor City. There are two types of drainage basins in Sudirman Street and delineated to two different catchment areas. The result of study shows that both of existing channels have enough capability to accommodate peak runoff until 5-year storm, yet the flash flood still occurs during the heavy rain. This is leading to conclusion that the existing inflow design is not effective to convey the runoff into existing drainage. So, the design solution is utilizing green area in the streetscape as a green infrastructure that give a multiple benefit to the environment such as filter, infiltrate, and convey storm water runoff slowly to the main drainage.
