: Flood has become an immense phenomenon in Pakistan. On August 2020 DHA Karachi was badly affected by urban flooding. This study discusses that poorly maintained drainage networks are the factors that caused urban flooding in DHA. This study aims to discover the factor that led to the urban flooding in DHA and what damages are caused. Methodology greatly includes questionnaires. GIS has been used for carrying out mapping of DHA surface drainage networks. The data collected from the questionnaires showed that poor drainage network was the main cause of urban flooding in DHA and phase 6 was mostly damaged as a lot of land encroachment has been done in this phase. Streets were mostly damaged as stagnant water caused crackers in them thus causing power outrage and difficulty in evacuation. This study may provide a guideline to disaster planning, management, and development authorities.
