Part of Lagos was flooded on Monday, following the ocean surge around Okun Alfa in Eti Osa Local Government Area of the state.
Environmentalists say the devastation being caused by the in the area may spread to other parts of the metropolis.
They warn that if the sea walls are not built across the Lekki Coastline to protect communities like Lafiaji the residents of the area will suffer from the same fate as Okun Alfa.
Meanwhile, the Civil Society Organisations have kicked against the order by the Lagos State Governor Akinwunmi Ambode for the demolition of all shanties and illegal structures around the creeks and waterfronts as part of measures to rid the state of crime and filth.
Addressing journalists in Lagos, the Executive Director, Spaces for Change, Victoria Ohaeri says what the government calls shanties are people's businesses, homes, schools and all they have.
The CSO called on the state government to use intelligence instead of demolition to tackle criminal activities and insecurity in the state.
