Abstract :In this study, certain design and analyses have been carried out to create sustainable stormwater management within the boundaries of the study area determined in Balıkesir city. In this context, novel design proposals have been developed for sustainable rainwater management in building and green areas. The potential amount of rainwater that could be harvested from building roof areas has been quantitatively assessed; the capacity of this water to meet the irrigation water needs of public green areas in the surrounding area has been analysed. In consequence of the study, in accordance with the design recommendations that underpin the efficient use of water, the hard floor coverings in the immediate vicinity of the buildings were re-evaluated by transforming them into permeable surfaces within the framework of sustainable urban design principles. In the design of the proposed urban furniture, integrated solar energy systems, rainwater harvesting and reuse, green space integration and user-friendly features are adopted as basic design principles. In the study, the annual rainwater harvest under the existing conditions was calculated as 1,006,724 litres. However, when the area was redesigned within the framework of blue-green infrastructure principles, the rainwater harvesting efficiency and annual water demand were determined as 1,723,104 litres/year and 1,500,000 litres/year, respectively. These results indicate that the proposed design significantly enhances water collection capacity and contributes to the sustainable management of water resources.
