Abstract

In recent years, many cities and rural areas are facing frequent waterlogging, run-off pollution, huge loss of resourceful rainwater, damaged ecosystem and many more rain water related problems. In regional perspective, how to construct a sustainable storm water management measures have been presented as an important issue in many cities and urban agglomeration in Nigeria. Ibeju Lekki area is usually faced with the problem of rain water leading to incessant flooding. This study therefore assesses storm water management in Ibeju-Lekki Area, Lagos state. The research employs a random sampling technique in selecting 204 (0.07  ) respondents for questionnaire administration. Descriptive and inferential statistical tools were employed in the analysis of the data. Pearson product moment correlation was used to test the relationship between the gradient analysis and vulnerability to runoff of Ibeju-Lekki. Also, the slope analysis of the study area was carried out using slope calculation. Findings revealed that natural green space, public parks and gardens and drainage system were the most available storm water management infrastructure in the area. The result of correlation analysis with r = 0.971 shows a strong positive correlation between gradient and vulnerability to runoff. The study concluded that physical planning policies such as thorough monitoring of building plan before approval and institution of effective development control agencies among others should be put in place to ensure proper management of storm water in Ibeju-Lekki local government area of Lagos state
