Impact of Flooding on Housing Development in Gani Fawehinmi Area, Ondo Town, Nigeria

ABSTRACT

This study examined the impact of flooding on housing development in Gani fawehinmi area, Ondo town, Nigeria.  Flood is any overland flow of water, over street, sufficient to cause significant damage to lives and property, nuisance and health hazards. Data for this study were collected from primary sources, through the administration of one hundred and twenty one (121) questionnaires on respondents in the study area. Results from this study revealed that high intensity of rainfall, dumping of refuse on drainage channels, poor construction of drainage channels and poor town planning practices are the main causes of flood problems in the study area. This study therefore recommends adequate drainage system, proper land use planning, construction of embankments, proper refuse disposal and environmental enlightenment programmes as a panacea to flood problems.
