Flooding is one of the most pressing hazards in the Philippines, causing widespread damage to lives, property, and livelihoods. To address this, the Department of Public Works and Highways (DPWH) has implemented numerous flood control projects in the Phili ppines, including the Quezon Province. Despite ongoing infrastructure investments, few studies have evaluated the effectiveness of these flood control projects from both technical and community perspectives. Thus, this study assessed the effectiveness of s elected projects in the 4th District of Quezon Province, focusing on their impacts on lives, property, the environment, and the economy, as well as residents’ satisfaction. Using a mixed – methods design, data were collected from 280 residents living near fl ood control structures, supplemented by interviews with municipal engineers and planning officers. Results indicated that the projects were effective in reducing flooding and improving community safety, with respondents reporting high satisfaction regardin g safety and moderate satisfaction regarding maintenance. However, qualitative findings revealed critical concerns, including river overflow in certain areas, siltation of waterways, and budget constraints that limit regular maintenance and monitoring. These findings highlight a discrepancy between high perceived effectiveness and underlying technical and sustainability challenges. The study concludes that while flood control projects strengthen community resilience, long – term effectiveness requires consist ent maintenance, ecological integration, and stronger institutional support.
