Flooding remains one of the most persistent environmental challenges confronting urban centers, particularly in developing countries such as Nigeria. This study investigates the application of urban drainage systems in flood reduction along Central Road, Oredo Local Government Area, Edo State, with emphasis on assessing existing drainage efficiency and developing sustainable solutions for stormwater management. The research integrates field observations, hydrological analysis, and Geographic Information System (GIS)-based spatial modeling to identify flood-prone zones, evaluate drainage capacities, and analyze runoff behavior within the study area. Findings reveal that the recurrence of flooding is largely attributed to inadequate drainage capacity, poor maintenance practices, and rapid urbanization, which increase surface runoff and hinder effective flow conveyance. Based on the hydrological and spatial analysis, the study proposes practical interventions including drainage channel redesign, desilting programs, installation of retention structures, and the integration of nature-based solutions to improve stormwater conveyance and enhance urban resilience. Community involvement and public awareness were also identified as critical components for long-term flood management. This research contributes to sustainable urban planning and flood mitigation efforts by demonstrating how GIS supported hydrological analysis can inform the design and optimization of urban drainage systems. The findings provide valuable insights and actionable recommendations for policymakers, engineers, and urban planners seeking to reduce flood vulnerability in similar urban environments.
