Abstract

This study examines the impact of perceptions of drainage adequacy and government responsiveness on flood impact and recovery outcomes in an urban Malaysian community. Using a convergent mixed-methods design, quantitative survey data from 88 flood-affected households were analyzed alongside thematic insights from open-ended responses. Significant associations were found between delayed assistance and public dissatisfaction, and between drainage perceptions and property damage. Qualitative findings reinforced the need for early warnings, improved drainage, and coordinated response systems. The results underscore the importance of timely intervention, infrastructure maintenance, and transparent governance to enhance community resilience and institutional trust in flood-prone environments.
