Lagos Flooding: Coastal Highway's Impact on Drainage

Lagos experiences persistent flooding, particularly in areas like Victoria Island, Lekki, and Ajah, attributed to its geographical position as a coastal city situated just above sea level. The construction of the coastal highway has intensified public debate about its role in exacerbating flooding, as social media amplifies concerns regarding drainage failures.

Climate change is identified as a significant factor, increasing rainfall intensity and sea levels, which complicates drainage systems' ability to manage stormwater effectively. The article emphasizes that flooding does not solely indicate drainage system failure; rather, it is influenced by broader hydrological dynamics and local construction activities that can temporarily alter drainage patterns.

Environmental and social impact assessments (ESIA) are often misunderstood, as they do not guarantee zero environmental impact but rather aim to identify and manage potential impacts throughout construction and operation phases. The need for proper management of these assessments and construction activities is crucial to mitigate localized flooding issues.
