Nairobi Maps 227 Flood Hotspots As El Niño Threatens 100,000 Residents

The Nairobi City County Government has identified 227 flood-prone hotspots ahead of anticipated El Niño rains, warning that up to 100,000 residents could face displacement in a worst-case scenario.

Speaking during the Second National Development Implementation Committee meeting in Nairobi, Governor Johnson Sakaja revealed that county teams have cleared 26 out of 61 critical drainage sites across 17 subcounties as part of ongoing efforts to desilt rivers, unblock waterways, and clear illegal structures along river channels.

To prepare for potential displacement, the county has collaborated with the Kenya Red Cross and the national government to map out emergency rescue centers using local schools and social halls.

Emergency Response Strategy

Governor Sakaja emphasized that the temporary shelters will serve primarily as registration hubs to facilitate direct support rather than functioning as long-term camps.

“We have a plan for that together with the Kenya Red Cross and the national government… We do not want to create IDP camps,” Sakaja said, explaining that cash transfer programs would be utilized to assist families. “If you set up dependency on a single location, they will never leave if they know there’s food [and] shelter… In Nairobi, if you give people some resources, cash transfers, they will find their way.”

Funding and Meteorological Warnings

Ongoing drainage and river clearance works require KSh 5.17 billion, supported by the county government alongside key partner agencies, including the Kenya Urban Roads Authority (KURA), the Kenya National Highways Authority (KeNHA), and the Kenya Red Cross.

Addressing public skepticism regarding weather alerts, Sakaja urged residents to rely on scientific forecasts from the Kenya Meteorological Department, which projects the onset of heavy rains with a 96 to 98 percent probability.

Meteorological data indicates temperature increases and sustained wet spells, with isolated heavy storms expected to persist through early 2027. While Nairobi’s drainage system can handle gradual rainfall, the governor noted that intense downpours over short durations pose the primary flooding threat to the capital’s infrastructure.
