<![CDATA[The flooding that occurred in Nyunyai Village, Rajabasa District, Bandar Lampung City was not solely caused by the accumulation of waste in the drainage channels, but was more influenced by the flow of water sent from the upstream area which is topographically higher. This phenomenon indicates a mismatch between the capacity of the existing drainage system and the volume of water runoff received by the area. This study aims to analyze the main causes of flooding in Nyunyai Village and formulate a strategy to optimize the drainage system as a more comprehensive and sustainable mitigation effort. The method used is a descriptive qualitative approach with data collection techniques in the form of in-depth interviews, field observations, and documentation studies. Interviews were conducted on June 7, 2026 with key informants, namely Mr. Afrizal as the local RT Head and Mrs. Sulami as an affected resident. The results of the study indicate that the flooding problem in this area is structural and requires technical interventions that include drainage channel normalization, increasing capacity, and watershed-based spatial planning (DAS). These findings align with various previous studies, which emphasize that urban flood management cannot rely solely on environmental hygiene approaches, but requires integrated drainage infrastructure planning focused on long-term risk mitigation.]]>
