Abstract: Flooding is an environmental hazard that needs appropriate control measures to stem the tide of occurrence. This paper examines: the characteristics of residents; causes and effects of flooding; and the flooding mitigation measures adopted by the people of Ilaje coastal communities of Ondo-State, Nigeria. The empirical research method was adopted to describe the causes and other variables associated with flooding in the study area. Primary data on socio-economic characteristics of respondents were captured using a structured questionnaire; while the Geographic Information System was used to analyze the Google Image of Ilaje Region on the vulnerability of communities to flooding. Twelve political Wards, were randomly selected for the administration of questionnaires in the study area. Ten percent (10%) sample size was adopted for questionnaire administration due to homogeneity characterizing the study population. Empirical analysis shows that, flooding is rampant between the months of November and March due to heavy rainfall and sea-surge. Raising of furniture, evacuation and construction of flood barriers were the adopted mitigation strategies. This paper canvasses regular channelization and dredging of water paths by appropriate local and state government agencies. In addition, a sustainable urban planning strategies is recommended for effective and sustainable mitigation measures.
