Abstract: The proposed Kwasa Damansara New Township is an on-going master development project on 2320 acres of land in Selangor, Malaysia. The key design objective for the proposed development is to create a new focal point that reflects the township of a 21st Century. In the effort to achieving a sustainable township that is green holistically, it was important to protect the sites’ ecology and develop a sustainable stormwater master plan that shall contribute towards environmental quality, which includes protection and conservation of the existing river system. Sungai Kedondong and its tributaries (Kedondong River) have been recognized as streams within the development boundary, which itself is a tributary of Sungai Buloh. Green infrastructure is strategically planned and will be managed to ensure that the ecosystem values and functions are well preserved and providing benefits to our daily life and costs less to install compared to traditional infrastructure system. It benefits the environment due to its minimal impact on local ecology and also minimal post-construction maintenance. By restoring vegetation using bio-engineering techniques, pollutants are filtered, promoting groundwater recharge, releasing oxygen into the atmosphere and thereby increasing wildlife habitat, which is our aim and goal to strive for a better future. Under such implementation, it can be safely indicated that there will also be no increase in flood discharge and frequency to the existing river resulting from the urban development, with results which are confirmed by hydrodynamic models for several different return periods. Therefore, efforts of this river management plan also concentrate the implementation of the flood mitigation master plan for Sungai Buloh catchment.
