Abstract
In recent years, many cities and rural areas are facing frequent waterlogging, run-of
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
