Sanwo-Olu, Umahi reject flood claims against Lagos-Calabar coastal highway
By Ezurike Ugochukwu
Lagos State Governor Babajide Sanwo-Olu and the Minister of Works, David Umahi, have dismissed claims that the ongoing Lagos-Calabar Coastal Highway is responsible for recent flooding in parts of Lagos, insisting that the project was engineered to improve flood resilience rather than worsen it.
The two officials spoke during a courtesy visit by the Minister of Works and members of the National Assembly to the Lagos State Government following widespread social media claims linking the highway to flooding in parts of the Lekki corridor.
Governor Sanwo-Olu described the reports as misleading, saying the state’s coastal geography naturally exposes it to seasonal flooding, while stressing that poor waste disposal and blocked drainage systems remain the major causes of flash floods.
He commended the Federal Government for embarking on what he described as one of Nigeria’s most significant infrastructure projects, noting that the Lagos-Calabar Coastal Highway would stimulate economic growth, improve connectivity and enhance the quality of life for millions of Nigerians.
“Two years ago, many people thought it was merely a political conversation, but today motorists are already using sections of the road,” the governor said.
“We appreciate President Bola Tinubu for this landmark project. Lagos has been one of the first major beneficiaries, and the road will improve economic activities while enhancing the quality of life of our people.”
Addressing the flooding concerns, Sanwo-Olu said Lagos, as a coastal city, would continue to experience some level of flooding during periods of intense rainfall.
“Lagos is a coastal city, and like many coastal cities around the world, some flooding is inevitable. Our responsibility is to ensure that it is effectively managed. We should not allow misinformation on social media to define our realities,” he said.
The governor maintained that while government remains committed to addressing environmental challenges, residents also have a responsibility to protect drainage infrastructure by avoiding indiscriminate refuse disposal.
According to him, blocked drainage channels remain one of the biggest contributors to urban flooding across the state, adding that the government will strengthen environmental regulations and enforcement to tackle the problem.
Sanwo-Olu also disclosed that the state has commenced a comprehensive clean-up of the Lagos-Badagry Expressway corridor as part of broader efforts to improve drainage efficiency and environmental sanitation.
Speaking during the visit, Minister Umahi said technical assessments showed that the Lagos-Calabar Coastal Highway did not cause the flooding recorded in parts of Lekki.

He explained that the highway was intentionally elevated to withstand storm surges and rising sea levels, adding that the corridor was originally a swampy terrain before construction commenced.
“The road was designed with long-term climate resilience in mind. It is built to protect the corridor against flooding and ocean surges for the next 20 to 30 years,” Umahi said.
He disclosed that the Federal Government and Lagos State Government would jointly develop additional drainage channels and service roads along the highway corridor to improve water evacuation, although some structures may have to be removed to accommodate the new infrastructure.
Umahi also praised the Lagos State Government’s drainage master plan, noting that over 80 per cent of the major drainage evacuation channels discharging into the lagoons have already been completed.
The Lagos State Government has consistently attributed worsening flash floods to environmental abuses, particularly indiscriminate refuse disposal and blocked drainage systems.
Commissioner for the Environment and Water Resources, Tokunbo Wahab, recently said the government has invested heavily in restoring drainage corridors and would continue strict enforcement against activities that obstruct waterways.
Authorities have repeatedly urged residents to stop dumping refuse into drainage channels, warning that blocked drains significantly increase the risk of flooding during heavy rainfall.
The renewed assurances from Sanwo-Olu and Umahi come amid heightened public scrutiny of the Lagos-Calabar Coastal Highway, with both governments insisting that improved drainage management, environmental compliance and climate-resilient infrastructure—not the highway itself—are central to reducing flood risks in Lagos.
