Water we all know is the most vital and prominent need of man. However, its unbelievable effect in 2012 across the
whole of West Africa showed that it can also cause untimely death, havoc, disaster and poverty when in excess. The
Nigerian hydrological service Agency (NIHSA) prediction of flooding being the number one natural disaster if global
temperature and climate changes continues on the rise came to reality in 2012 where over 23 states of the nation was
ravaged by horrendous flooding. This was the worst in the history of the country’s existence. This was an eye opener to
the African continent towards there planning applications for development of their various cities in flood zones and its
degree of practice and effectiveness. SUDS (sustainable drainage system) and rainwater harvesting were aspects that
couldn’t find its grip in the country’s flood management plan. Therefore, this work is focused on addressing those
precarious situations by carrying out a risk assessment on Nigerian statessited on flood plains and producing a feasible
flood management strategy and guideline to planners and developers using the Wales technical guideline planning policy
for development and flooding (TAN 15) and NPPF (technical guidance to help local planning authorities implement
national planning policy and framework superseded PPS 25) as guidelines to providing a standard guide for the
developers and planners in the African continent. Good design principles and more sustainable drainage systems which
are much suitable for the African environment is to be encouraged and adopted into practice by this work and total
abolishment of the gutter and tunnel system.
