In communities like those near Topeka’s Shunganunga Creek, where flooding is a frequent and expected part of life, risk communication must adapt to meet the unique circumstances of residents. To understand how people in this floodplain perceive risk and respond to flood warnings, we interviewed 11 residents, guided by principles from Protection Motivation Theory. Participants, including long-time community members and local educators, shared how they perceive risk messages and make protective decisions during flood events. We identified key communication barriers through qualitative thematic analysis, including distrust of official sources, accessibility issues, and reliance on social networks for information. Our study highlights that official warnings emphasize scientific accuracy but do not always align with how at-risk populations interpret and respond to risk. Traditional top-down communication strategies often struggle to account for the localized needs of communities, leading to disregard and inaction from residents. We recommend tailoring flood risk communication to be clear and relatable, addressing the unique circumstances of floodplain communities. Shifting toward community-centered outreach, incorporating trusted local figures, assistance information, and cultural relevance will strengthen resilience against future flooding in a changing climate.
