Topic overview
Flooding is a growing problem in coastal cities like Miami, driven by heavier rainfall, sea‑level rise, and rapid urban growth. Understanding how people perceive flood risk and act to prepare is essential to building resilience.


Paper overview
We surveyed 702 households in Miami‑Dade County in 2024 to explore how residents’ flood risk perceptions, trust in government, previous flood experiences, and personal confidence influence whether they prepare their homes.


Findings summary
We found that worry about flooding—especially storm surge (83%)—and belief that risks are increasing (50%) are widespread, even though most (97%) support public investments in flood infrastructure. Over half of residents (52%) reported taking preparedness actions. Importantly, residents who feel more able to protect themselves (higher self‑efficacy), who believe protective actions are effective (higher response efficacy), and who perceive lower costs are more likely to act—especially when combined with their demographic background and flood experiences.


Key takeaways
These insights reveal how psychological perceptions, trust, and experience work together to drive household flood preparation. Understanding this mix helps policymakers and modelers predict risk behaviors and integrate preparedness into planning and flood‑adaptation strategies.
