Ogun state government alerts residents on imminent flooding

The Ogun State Government has alerted residents of the wetland areas to relocate to safer ground before the rain commences fully, warning against imminent flooding as rain gets momentum for heavy downpour in due course.

“It is either you relocate from the area or you elevate; may be you want to reconstruct your house or do some kind of elevation if you must stay in that area. Every year, we talk about relocation. It is not easy to relocate. If you must leave in those areas, make sure that your electronics, your chairs, whatever can be damaged is being  elevated”, he stated.

“When we talk about relocation and elevation, it is going to be predominantly around this area. People leaving within the wetland of the state are supposed to prepare for this increase in the height of the water because we are going to have a retention of this lockdown around this period”,Oresanya added

“So, people who are located in the hill areas are going to have some kind of erosion because of the speed the water will take in running down around the Ilaro area and some areas in Ota. We are going to have what we call erosion that is going to accompany this kind of flooding for the year”, he said.

“The other areas that we will have the impact which is later on are people that are leaving within the wetland of the state and the wetland area are predominantly Southern parts of the state and this are almost flat land, low line land because this are the border towns between Lagos and Ogun State’, the Commissioner stressed
